Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to an automatic polishing device for ball-shaped parts. Background Technology

[0002] A ball joint is a common mechanical structure consisting of a spherical head and a mating seat. The ball head can rotate freely within the seat, enabling rotation at multiple angles and in multiple directions. To reduce the friction between the ball head and the ball head seat, the processing of ball head parts usually includes a polishing process. Currently, polishing is generally done manually by clamping the parts and operating the equipment, which is inefficient for batch processing needs. Utility Model Content

[0003] The purpose of this invention is to provide an automatic polishing device for ball-head parts to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic polishing device for ball-shaped parts, comprising a machine base, a material rack a, and a material rack b. A drive motor is fixedly installed on the upper side of the machine base, and a polishing wheel is fixedly installed on the output shaft of the drive motor. The material racks a and b are respectively located on the left and right sides of the machine base. Two parallel support frames are fixedly installed on the upper side of the machine base. A two-dimensional linear module is installed between the lower sides of the two support frames. A crossbeam is installed at the lower end of the two-dimensional linear module. Clamping cylinders are respectively installed at the lower ends of the crossbeam. A horizontally movable support is installed on the upper side of the machine base via a slide rail. A polishing auxiliary wheel is installed in the support. The polishing auxiliary wheel and the polishing wheel are arranged opposite each other. A spring a is installed on the outer side of the support. A stop seat is installed on the upper side of the machine base. The outer end of the spring a is fixedly connected to the stop seat. The spring a pushes the polishing auxiliary wheel towards the polishing wheel. The two-dimensional linear module is located above the polishing auxiliary wheel and the polishing wheel.

[0005] Preferably, the polishing wheel and the polishing auxiliary wheel have the same diameter and multiple sets of annular grooves are provided on the outer side along the circumference.

[0006] Preferably, a guide groove is fixedly installed on the upper side of the machine tool, a polishing wax block is provided in the guide groove, and a spring b is provided in the guide groove. The spring b applies a pushing force to the polishing wax block to keep it in contact with the polishing wheel.

[0007] Compared with the prior art, the beneficial effects of this utility model are: this device uses a clamping cylinder installed on a two-dimensional linear module to grab the ball head workpiece onto the polishing wheel for grinding and polishing. After polishing, it is then grabbed to the other side for unloading. This device is conducive to improving the polishing efficiency of ball head parts and reducing labor costs.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0011] Please see Figure 1 This utility model provides a technical solution: an automatic polishing device for ball head parts, including a machine base 1, a material rack a12 and a material rack b13. A drive motor 2 is fixedly installed on the upper side of the machine base 1, and a polishing wheel 3 is fixedly installed on the output shaft of the drive motor 2. A guide groove 7 is fixedly installed on the upper side of the machine base 1, and a polishing wax block 9 is provided in the guide groove 7. A spring b8 is provided in the guide groove 7, and the spring b8 applies a pushing force to the polishing wax block 9 to keep it in contact with the polishing wheel 3, so that the polishing wax block 9 is gradually applied to the polishing wheel 3. The material rack a12 is used to place the ball head workpiece to be polished, and the material rack b13 is used to place the processed ball head parts (the tail of the ball head part is provided with a rod, which is also used to clamp the rod when gripping).

[0012] Material racks a12 and b13 are respectively set on the left and right sides of machine base 1. Two parallel support frames 14 are fixedly installed on the upper side of machine base 1. A two-dimensional linear module 10 (commercially available mature product) is installed between the lower sides of the two support frames 14. A crossbeam is installed at the lower end of the two-dimensional linear module 10. Clamping cylinders 11 are respectively installed at the lower ends of the crossbeam. The two-dimensional linear module 10 is used to drive the clamping cylinders 11 to move laterally and lift. The clamping cylinders 11 are used to grab and transfer workpieces. The two clamping cylinders 11 are used for loading and unloading, which helps to reduce the lateral movement. The clamping claws of the clamping cylinders 11 are provided with arc-shaped grooves. The arc-shaped grooves are used to engage with the rod of the ball head when clamping. The rod of the ball head can rotate around the axis after being clamped.

[0013] A horizontally movable support 4 is mounted on the upper side of the machine base 1 via a slide rail. A polishing auxiliary wheel 5 is installed in the support 4. The polishing auxiliary wheel 5 and the polishing wheel 3 are arranged opposite each other. The polishing wheel 3 and the polishing auxiliary wheel 5 have the same diameter and multiple sets of annular grooves along their outer circumference. The annular grooves can form more contact surfaces with the ball head, improving polishing efficiency. A spring a6 is installed on the outer side of the support 4. A stop seat is installed on the upper side of the machine base 1. The outer end of the spring a6 is fixedly connected to the stop seat. The spring a6 pushes the polishing auxiliary wheel 5 towards the polishing wheel 3. The two-dimensional linear module 10 is located above the polishing auxiliary wheel 5 and the polishing wheel 3. The ball head is polished between the polishing wheel 3 and the polishing auxiliary wheel 5.

[0014] Working principle: During use, the drive motor 2 drives the polishing wheel 3 to rotate. The two-dimensional linear module 10 drives the clamping cylinder 11 at the end to move and grab the workpiece to be polished between the polishing wheel 3 and the polishing auxiliary wheel 5. The annular grooves of the two wheels contact the spherical surface of the ball head for grinding and polishing. After polishing, the workpiece is grabbed to the material rack b13 on the other side for unloading. When the ball head is being polished, it is stuck on the upper part of the polishing auxiliary wheel 5 and the polishing wheel 3. The polishing wheel 3 drives the ball head to rotate, and the ball head then drives the polishing auxiliary wheel 5 to rotate. However, their rotations are not synchronized (i.e., there is a difference in linear velocity), thus enabling the polishing to cover the spherical surface.

[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
