Thereby, when the piston rod of the present invention is in the retracted position, the magnetic member can attract the magnetic end of the moving assembly to form a locking effect, which can prevent the piston rod from sliding out when the air pressure of the pressure cylinder is insufficient or pressure loss Pressing the cylinder causes the tool sleeve to sag, which affects the tool change operation of the tool change arm.

Furthermore, the present invention has simple structure, low cost, fast installation and industrial competitiveness.

The exemplary embodiments of the present invention are described in detail below with reference to the drawings, and are not intended to limit the technical principles of the present invention to specific disclosed embodiments, and the scope of the present invention is only limited by the scope of the patent application, covering alternatives, modifications and Equivalent.

Please refer to FIGS. 1 to 5, the present invention is a tool magazine rewinding device with magnetic lock, which includes a cylinder 10, a connecting piece 20, a moving assembly 30 and a magnetic piece 40. The tool magazine rewinding device with magnetic lock of the present invention is arranged in the tool magazine 1 to cooperate with the tool change operation.

The pressure cylinder 10 is an air cylinder or a hydraulic cylinder. In the embodiment of the present invention, the air cylinder is used for description. The pressure cylinder 10 has a first end 11 and a second end 12, and a telescopic piston rod 13 extends from the second end 12. Wherein, one side of the pressure cylinder 10 is provided with a fixing seat 50 for fixing the pressure cylinder 10 to the tool magazine 1; the second end 12 of the pressure cylinder 10 is provided with two guide holes 14.

The connecting piece 20 is in the shape of a rectangular plate. The connecting piece 20 is connected to the end of the piston rod 13 and is connected to the knife holder 2 through an inverted knife block 21. The knife holder 2 has a pivot 2a and is pivoted. In the tool magazine 1, the tool holder 2 also has a roller 2b and is clamped on the inverted tool block 21. When the piston rod 13 of the cylinder 10 is in the retracted position, the tool holder 2 is generally horizontal as shown in FIG. At this time, the knife sleeve 2 is in a higher position, and as shown in FIG. 4, when the piston rod 13 of the pressure cylinder 10 is in the extended position, the knife sleeve 2 is vertical and in a lower position.

The moving assembly 30 is slidably disposed on the periphery of the pressure cylinder 10 in parallel with the moving direction of the piston rod 13, and the moving assembly 30 has a connecting end 31 and a magnetic end 32. The connecting end 31 and the piston rod 13 are jointly connected to the connection 20, so that when the piston rod 13 is actuated, the moving assembly 30 produces a sliding movement relative to the pressure cylinder 10. In the embodiment of the present invention, the moving assembly 30 is two guide rods 33 extending through the guide hole 14, and the connecting end 31 and the magnetic end 32 are respectively provided at both ends of the guide rod 33.

The magnetic member 40 is a powerful magnet and is provided at the first end 11. The magnetic member 40 can be magnetically attracted to the magnetic end 32 to lock the piston rod 13 to prevent the knife sleeve 2 from falling. In the embodiment of the present invention, the magnetic attraction force of the magnetic member 40 is greater than the weight of the knife holder 2 and the tool, so that when the piston rod 13 is in the retracted position relative to the cylinder 10, the magnetic member 40 is used to attract the magnetic force of the moving assembly 30. End 32, so as to prevent the pressure cylinder 10 from losing pressure (such as insufficient air pressure), the knife sleeve 2 or the knife sleeve 2 equipped with the tool will not slide the piston rod 13 out of the pressure cylinder 10 due to the gravity of the knife sleeve 2 and cause the knife sleeve 2 The problem of sagging occurs.

Wherein, the present invention further includes a second magnetic plate 41 coupled to the first end 11, and the magnetic end 32 is a first magnetic plate. The second magnetic plate 41 carries the strong magnet so that the magnetic element 40 and the first magnetic The plates attract each other. In other embodiments, the magnetic member 40 and the first magnetic plate may be a combination of two magnetically attracted magnets or a combination of a magnet and a magnetic metal, which can achieve the same magnetic attraction effect.

In the embodiment of the present invention, the first magnetic plate is U-shaped, and its concave portion corresponds to the periphery of the pressure cylinder 10. One end of the aforementioned guide rod 33 is locked to the connecting member 20, and the other end is locked to the first magnetic plate; The second magnetic plate 41 is U-shaped, which is roughly similar to the first magnetic plate. There are four strong magnets and each is disc-shaped. The strong magnet further includes two large strong magnets 42 and two small strong magnets 43. They are arranged on both sides of the second magnetic plate 41 in groups of one large and one small.

As shown in FIG. 5, when the piston rod 13 is in the retracted position relative to the cylinder 10, the magnetic end 32 (ie, the first magnetic plate) of the moving assembly 30 is attracted by the strong magnet 42 and the small strong magnet 43 of the magnetic member 40 ), the locking effect is formed in this way, and the piston rod 13 can be prevented from sliding out due to the weight of a single tool holder 2 or the weight and influence of a single tool holder 2 and a single tool when the air pressure of the cylinder 10 is insufficient or depressurized Pressing the cylinder 10 causes the tool sleeve 2 to sag, which affects the tool change operation of the tool change arm and avoids related risks.

Furthermore, the present invention has a simple structure and a lower cost than the conventional self-locking cylinder. At the same time, the movable assembly 30 and the magnetic member 40 are attracted to form a lock, and the movable assembly 30 can also be used as a guide for the telescopic action of the piston rod 13. Guide, make the knife action more stable and reliable.
