Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
The embodiment discloses a bolt sieving mechanism. As shown in fig. 1, the bolt screening device comprises a contact detection assembly, a display structure 2, a height adjustment structure 3 and a displacement structure 4, wherein the contact detection assembly can be contacted with a bolt 5 to be detected, and the contact detection assembly sends out a qualified signal when the length of the bolt 5 to be detected is equal to a set value; the display structure 2 can receive the qualified signal and display the length detection result of the bolt 5 to be detected, namely, whether the bolt is qualified or unqualified is displayed in a lighting mode; the height adjusting structure 3 is used for adjusting a set value, and the set value is equal to the length of the bolt 5 to be detected or accords with a certain corresponding relation with the length of the bolt 5 to be detected; the displacement structure 4 is used for driving the contact detection assembly to reciprocate, so that the contact detection assembly can contact the bolt 5 to be detected.
The contact detecting assembly preferably includes a detecting lever 11 and a signal generating structure, the detecting lever 11 being adapted to be brought into contact with the bolt 5 to be detected, thereby judging whether the length of the bolt 5 to be detected is equal to a set value. When the length of the bolt 5 to be detected is equal to the set value, the signal generating structure can generate a signal read by the display structure 2.
The detection rod 11 is used for being in contact with the bolt 5 to be detected to detect whether the length of the bolt 5 to be detected is equal to a set value, three-dimensional scanning, a distance sensor and other structures are omitted, the product cost is lower, the recognition speed is faster, and the problem that the installation of the electric appliance bolt is easy to make mistakes is solved.
The specific composition of the signal generating structure is not limited, and a signal can be generated when the length of the bolt 5 to be detected is equal to a set value. Preferably, the signal generating structure includes two conductive blocks 12 and wires 16 connected to the conductive blocks 12, respectively, the two conductive blocks 12 being disposed opposite to each other with a distance therebetween equal to the length of the detection bar 11. The height of the conductive block 12 is 1mm, the tolerance of the height of the bolt 5 to be detected is +/-0.5 mm, and the detection within the tolerance range can be met.
When not in use, the two conductive blocks 12 are respectively positioned above the two sides of the detection rod 11; when the detection rod 11 is used, the detection rod is contacted with the bolt 5 to be detected and is jacked up by the bolt 5 to be detected for a certain distance, when the two ends of the detection rod 11 are simultaneously contacted with the two conductive blocks 12, the circuit of the electric wire 16 is conducted, the indicator lamp 21 on the display structure 2 is shiny, the length of the bolt 5 to be detected is equal to a set value, and the selected bolt 5 to be detected is correct; if the indicator lamp 21 on the display structure 2 is not on, it indicates that the length of the bolt 5 to be detected is not equal to the set value, and the selected bolt 5 to be detected is wrong.
Based on the above structure, the detection rod 11 is preferably a hollow tubular structure, in which the detection spring 13 is disposed, and two balls 14 are respectively disposed at two ends of the detection spring 13. When the detection rod 11 is not in contact with the conductive block 12, the detection spring 13 pushes the two balls 14 to slightly move outward; when the detection lever 11 is just abutted against the conductive block 12, the two balls 14 approach each other under the pushing of the respective corresponding conductive block 12, thereby pressing the detection spring 13 to slightly deform. The detecting spring 13 applies pressure to the ball 14, so that the ball 14 is abutted with the conductive block 12 more tightly, and accidental disconnection of the circuit of the electric wire 16 is avoided.
In view of the fact that the length of the bolt 5 to be detected has three states equal to, greater than or less than the set value, there are three possibilities that the position of the detecting rod 11 is in abutment with the bolt 5 to be detected, the contact detecting assembly further comprises a height spring 15, one end of the height spring 15 is connected to the detecting rod 11, and the other end is fixedly connected to the housing 17 of the contact detecting assembly. The height spring 15 allows the detection rod 11 to be located at a corresponding position regardless of the length of the bolt 5 to be detected compared with the set value, avoiding damage to at least one of the detection rods 11 due to excessively strong abutment with the bolt 5 to be detected.
The height adjusting structure 3 is provided with a graduated scale so as to intuitively display the height value of the required selection bolt. The displacement structure 4 is preferably a rod-shaped structure, the rod-shaped structure is movably mounted on the height adjusting structure 3 through the knob 41, and when the height of a bolt to be selected is changed, the knob 41 is only required to be loosened, the displacement structure 4 is adjusted to the corresponding scale, and then the knob 41 is locked again. The bolt screening device preferably uses the feed belt 7 to continuously convey the bolts 5 to be detected, thereby improving the detection efficiency.
Each structure of this bolt sieving mechanism is spare part (for example have conductive function's iron plate, cylinder and spring etc.) commonly used, and the theory of operation that adopts is simple conductive circuit break-make, convenient to use, and it is accurate and efficient to measure, and later maintenance is also comparatively simple.
The using method of the bolt screening device comprises the following steps:
The knob 41 is released, the displacement structure 4 is adjusted to the scale corresponding to the height value of the required selection bolt, and then the knob 41 is locked again. The opening drive drives the displacement structure 4 downwards or manually presses down the displacement structure 4 until the displacement structure 4 moves to the lowest end of the stroke. When the distance between the top end of the bolt 5 to be detected and the detection rod 11 is smaller than the total stroke value of the downward movement of the displacement structure 4, the detection rod 11 is abutted against the bolt 5 to be detected in the downward movement process of the displacement structure 4.
As shown in fig. 2, if the length of the bolt 5 to be detected is equal to the set value, the detecting rod 11 is moved up between the two conductive blocks 12, the electric wire 16 is electrified, and the indicator lamp 21 on the display structure 2 flashes to indicate that the bolt 5 to be detected is a qualified product. The displacement structure 4 is reset, the feeding belt 7 moves forward, and the next bolt 5 to be detected is detected.
As shown in fig. 3, if the length of the bolt 5 to be detected is smaller than the set value, the detecting rod 11 cannot reach the height of the two conductive blocks 12 after being moved up, the circuit of the electric wire 16 cannot be conducted, the indicator lamp 21 on the display structure 2 does not flash, the bolt 5 to be detected is prompted to be a defective product, and the next detection of the bolt 5 to be detected is performed again after waiting for confirmation processing. When the distance between the top end of the bolt 5 to be detected and the detecting rod 11 is greater than the total stroke value of the downward movement of the displacement structure 4, the displacement structure 4 cannot make the bolt 5 to be detected and the detecting rod 11 abut against each other even if the distance is smaller than the total stroke value, and the bolt 5 to be detected is not qualified.
Similarly, as shown in fig. 4, if the length of the bolt 5 to be detected is greater than the set value, the circuit of the electric wire 16 cannot be conducted at the position of the height of the two conductive blocks 12 after the detection rod 11 moves upwards, the indicator lamp 21 on the display structure 2 does not flash, the bolt 5 to be detected is prompted to be a defective product, and the detection of the next bolt 5 to be detected is performed again after waiting for the confirmation processing.
Example two
The embodiment discloses a bolt screening device, and the structure and the working principle of the bolt screening device are basically the same as those of the first embodiment. The difference is that, as shown in fig. 5, a first conductive contact piece 61 is provided on the end of the contact detection assembly, a second conductive contact piece 62 is provided on the displacement structure 4, a third conductive contact piece 63 is provided on the slide rail of the displacement structure 4, and the first conductive contact piece 61, the second conductive contact piece 62 and the third conductive contact piece 63 can be electrically connected when the displacement structure 4 moves to the set position.
After the height spring is removed, the detection rod 11 can only rigidly contact the bolt 5 to be detected. When in use, the displacement structure 4 is adjusted to the scale corresponding to the height value of the required selected bolt, and then the displacement structure 4 is moved downwards. The difference is that an electrode 8 needs to be clamped on the bolt 5 to be detected. When the length of the bolt 5 to be detected is equal to a set value, the first conductive contact piece 61 is abutted against the top end of the bolt 5 to be detected, the second conductive contact piece 62 is abutted against the third conductive contact piece 63, the third conductive contact piece 63 is connected with another electrode, the whole electric reflux is conducted, the indicator lamp 21 on the display structure 2 shines, and the bolt 5 to be detected is indicated to be qualified; when the length of the bolt 5 to be detected is smaller than the set value, the displacement structure 4 moves downwards to the lowest point, the second conductive contact piece 62 is abutted against the third conductive contact piece 63, but the first conductive contact piece 61 is not abutted against the top end of the bolt 5 to be detected, so that the whole electric reflux cannot be conducted, and the indicator lamp 21 on the display structure 2 does not flash; when the length of the bolt 5 to be detected is greater than the set value, the first conductive contact piece 61 is already abutted against the top end of the bolt 5 to be detected when the displacement structure 4 moves down to the lowest point, and at this time, the displacement structure 4 cannot be continuously pressed down, so that the second conductive contact piece 62 cannot be contacted with the third conductive contact piece 63, the whole electric reflux cannot be conducted, and the indicator lamp 21 on the display structure 2 does not flash.
