technical field

The utility model relates to a mechanical device, namely a reciprocating ultrasonic vibration finishing device.

Background technique

Finishing is one of the important processes in mechanical processing. Its content is to improve the smoothness of the surface of the part by removing the excess part of the surface of the part, and it can also be said to reduce the roughness of the surface of the part. We know that all kinds of mechanical processing, whether it is cutting processing, or casting, forging, stamping, etc., almost inevitably leave certain defects on the surface of parts, such as uneven surface, obvious convex ribs, knife marks ripples, flashes, Burrs, microscopic cracks, etc. These defects directly affect the appearance quality and performance of the parts, and seriously cause the quality and performance indicators of the whole machine to decline. The appearance and performance of the product can only be guaranteed by finishing the parts to achieve an appropriate finish. With the advancement of science and technology, industrial products have higher and higher requirements for performance and service life. This puts forward higher requirements on the machining accuracy and surface quality of machined parts. The size, geometry, and surface position of parts are required to have high precision and low surface roughness. Therefore, new requirements are put forward for the level of finishing processing technology and equipment. The finishing and finishing of many mechanical parts has become a necessary technical requirement for drawings, and a large number of technical standards have been formed. The current finishing processing methods mainly include grinding processing, abrasive processing, electrochemical processing, superfinishing processing, etc. The equipment is relatively complicated and the processing cost is relatively high. For simple parts processing, such as deburring, sharp corners, etc., it is usually carried out by manual or semi-manual methods such as files, cloth wheels, emery cloth, abrasive belts, etc., which is difficult to meet the needs of the rapid development of the mechanical processing industry.

Detailed ways

The first embodiment: as shown in Figures 1, 2, and 3, the main body of this reciprocating ultrasonic vibration finishing device is a cubic frame, and a transmission mechanism is installed at the bottom of the frame. There are many ways for the transmission mechanism. The mechanism is a crank rocker mechanism. That is, the power output shaft of the motor drives the driving gear 2, the driving gear 2 drives the driven gear 3, and the gear shaft 9 of the driven gear 3 drives a crank 10, one end of the crank 10 is hinged to the connecting rod 11, and the other end of the connecting rod 11 is connected to the The middle part of rocking bar 12 is hinged, and the lower end of rocking bar 12 is hinged with frame 1, and the upper end is hinged with pull bar 8, and the other end of pull bar 8 is hinged with tackle 5. When working, put the granular abrasives and the workpiece to be processed into the carriage 6 together, start the motor, and the turnover motion of the motor will be converted into the planar reciprocating motion of the pulley 5, and the abrasive in the carriage 6 and the workpiece will produce relative violent motion. So as to achieve the purpose of finishing the workpiece.

The crank rocker mechanism here has a small extreme angle (about 5°), and the stroke speed ratio coefficient K of a pulley can be obtained from the formula K=(180+θ)/(180-θ), so in the extreme position , The stop time of the pulley is very short, which is conducive to processing. When the crank angle a of the crank slider mechanism is not equal to zero, the relationship between the slider stroke S and the crank angle a, that is, the transmission characteristics, is nonlinear. From this, it can be seen that the motion characteristics of the pulley are nonlinear, and the relative motion between the abrasive and the workpiece is relatively severe. Conducive to processing.

The second embodiment: as shown in Figure 4, the mode of this example is that the power output shaft of the motor drives the driving gear 2, the driving gear 2 drives the driven gear 3, and the gear shaft 9 of the driven gear 3 drives a crank 10, and the crank 10 Drive connecting rod 11, and connecting rod 11 directly drives a tackle 5. This example illustrates that, in addition to the transmission mode of the first embodiment, other transmission mechanisms can also be adopted. As long as the mechanism that can make the high-speed reciprocating motion of the tackle 5 all should belong to the equivalent technical scheme.

The third embodiment: as shown in Figure 5, the base plate 14 of the carriage 6 of the tackle 5 is a curved plate with high front and rear and low middle, this shape is conducive to the mutual collision of materials in the case, and improves the friction efficiency.

In addition, the carriage 6 is also provided with a case cover 13, which can be closed after charging. Especially below the carriage 6, an ultrasonic vibrator 15 is installed, which can cause the carriage 6 to generate high-frequency vibration, so that the carriage 6 has reciprocating motion and high-frequency vibration at the same time, which can significantly enhance the intensity of the vibration, and aggravate the wear and tear of the abrasive particles. The collision impact of the workpiece produces a better surface finishing effect. According to experiments, this device has the following advantages:

1. Reliably remove machining burrs of parts, round sharp edges and sharp corners;

2. Effectively remove residues, impurities and oxide scales on the surface of castings, forgings and heat treatment parts;

3. On the original basis, refine the surface roughness of parts processing to grade 1-2;

4. Improve the stress state of the surface layer of the part and form a uniform compressive stress value that is resistant to fatigue damage;

5. Improve the metallographic structure of the surface layer of the part, increase the surface microhardness, and form a dense metal layer that is wear-resistant and fatigue-resistant;

6. Improve the cleanliness of parts, complete the initial wear of transmission parts, improve some performance indicators of the whole machine, and shorten the running-in period of the whole machine by more than 40%;

7. Reduce process costs, reduce labor intensity of workers, improve production efficiency, no pollution, and facilitate mechanized and automated production.
