[0017] Beneficial effects

[0018] This utility model provides a tooling for polishing hardware parts. Compared with the prior art, it has the following advantages:

[0019] 1. This hardware polishing fixture, when it is necessary to polish the pipe, first start the second servo motor to drive the second lead screw to rotate. The rotation of the second lead screw will cause the second mounting bracket to move backward. Then, the pipe to be polished is placed in the three-jaw chuck in the second mounting bracket for clamping and fixing. Then, reverse the output shaft of the second servo motor to drive the second lead screw to reverse, thereby causing the second mounting bracket to move closer to the first mounting bracket. Finally, the three-jaw chuck in the first mounting bracket clamps the other end of the pipe. Then, start the first servo motor to drive the three-jaw chuck to rotate, so that the pipe can rotate accordingly.

[0020] 2. This hardware polishing fixture, by starting the second drive motor, drives the first slide rod to rotate. Under the restriction of the transmission bar, it can drive the polishing wheel to rotate, thereby polishing the outer wall of the pipe. Starting the first drive motor, it drives the first lead screw to rotate. The rotation of the first lead screw will cause the nut block to move back and forth in a linear motion. The nut block will drag the polishing wheel back and forth while rotating through the protruding ring. In this way, the entire outer wall of the pipe can be polished. By starting the cylinder, the assembly plate and docking block are pushed to move on the guide rail groove, thereby precisely controlling the distance between the polishing wheel and the pipe, preventing the thickness of the pipe side wall from being polished unevenly.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4 This application provides a tooling for polishing hardware parts, including a base 1, a polishing assembly 2 on the top of the base 1, and a clamping assembly 3 on the top of the base 1. The polishing assembly 2 includes an assembly plate 21, an auxiliary block 22 fixedly connected to the top of the assembly plate 21, a first lead screw 23 rotatably connected between one set of auxiliary blocks 22, a first slide rod 25 rotatably connected between another set of auxiliary blocks 22, a transmission bar 27 fixedly connected to the outer wall of the first slide rod 25, a polishing wheel 28 slidably connected to the outer wall of the first slide rod 25 and the transmission bar 27, protruding rings 29 fixedly connected to both sides of the polishing wheel 28, a nut block 26 threadedly connected to the outer wall of the first lead screw 23, and a rotatably connected protruding ring 29 to the inner side wall of one side of the nut block 26. A first drive motor 212 and a second drive motor 213 are fixedly mounted on one side of the assembly plate 21. The output shaft of the first drive motor 212 is fixedly connected to one end of the first lead screw 23, and the output shaft of the second drive motor 213 is fixedly connected to one end of the first slide rod 25. A mating block 210 is fixedly connected to the bottom of the assembly plate 21, and a guide rail groove 211 is fixedly connected to the top of the base 1. The mating block 210 is slidably connected to the outer wall of the guide rail groove 211. A cylinder 24 is fixedly installed on the top of the base 1, and the movable end of the cylinder 24 is fixedly connected to one side of the assembly plate 21.

[0030] In specific implementation: by starting the second drive motor 213 to drive the first slide bar 25 to rotate, and under the restriction of the transmission bar 27, the polishing wheel 28 can be driven to rotate to polish the outer wall of the pipe. Starting the first drive motor 212 will drive the first lead screw 23 to rotate. The rotation of the first lead screw 23 will cause the nut block 26 to move back and forth in a straight line. The nut block 26 will drag the polishing wheel 28 to move back and forth while rotating through the protruding ring 29. In this way, the entire outer wall of the pipe can be polished. By starting the cylinder 24, the assembly plate 21 and the docking block 210 are pushed to move on the guide rail groove 211, thereby precisely controlling the distance of the polishing wheel 28 from the pipe and preventing the thickness of the pipe side wall from being polished unevenly.

[0031] Reference Figures 1 to 4 In one aspect of this embodiment, the clamping assembly 3 includes a first mounting bracket 31, which is fixedly connected to the top of the base 1. A three-jaw chuck 32 is rotatably mounted inside the first mounting bracket 31. A first servo motor 33 is fixedly mounted on the top of the base 1, and the output shaft of the first servo motor 33 is fixedly connected to one side of the three-jaw chuck 32. A guard plate 35 is fixedly connected to the top of the base 1. A second slide rod 36 is fixedly connected between the two guard plates 35. A second mounting bracket 34 is slidably connected to the outer walls of the two second slide rods 36. The second mounting bracket 34 is slidably connected to the top of the base 1. A second lead screw 37 is also rotatably connected between the two guard plates 35. The outer wall of the second lead screw 37 is threadedly connected to the inside of the second mounting bracket 34. A second servo motor 38 is fixedly mounted on one side of the base 1, and the output shaft of the second servo motor 38 is fixedly connected to one end of the second lead screw 37.

[0032] In practice: When the pipe needs to be polished, the second servo motor 38 is started to drive the second lead screw 37 to rotate. The rotation of the second lead screw 37 will cause the second mounting bracket 34 to move backward. Then, the pipe to be polished is placed in the three-jaw chuck 32 inside the second mounting bracket 34 for clamping and fixing. Then, the output shaft of the second servo motor 38 is reversed to drive the second lead screw 37 to reverse, thereby causing the second mounting bracket 34 to move closer to the first mounting bracket 31. Finally, the three-jaw chuck 32 inside the first mounting bracket 31 clamps the other end of the pipe. Then, the first servo motor 33 is started to drive the three-jaw chuck 32 to rotate, so that the pipe can rotate accordingly.

[0033] All electrical devices in this plan are powered by an external power source.

[0034] Working principle: When polishing the pipe is required, the second servo motor 38 is first started to drive the second lead screw 37 to rotate. The rotation of the second lead screw 37 causes the second mounting bracket 34 to move backward. Then, the pipe to be polished is placed into the three-jaw chuck 32 inside the second mounting bracket 34 for clamping and fixing. Then, the output shaft of the second servo motor 38 is reversed to drive the second lead screw 37 to rotate in reverse, thereby causing the second mounting bracket 34 to move closer to the first mounting bracket 31. Finally, the three-jaw chuck 32 inside the first mounting bracket 31 clamps the other end of the pipe. Then, starting the first servo motor 33 can drive the three-jaw chuck 32 to rotate, so that the pipe can rotate accordingly. By starting the second drive motor... 213 drives the first slide bar 25 to rotate, which in turn drives the polishing wheel 28 to rotate under the restriction of the transmission bar 27, thereby polishing the outer wall of the pipe. The first drive motor 212 is started, which drives the first lead screw 23 to rotate. The rotation of the first lead screw 23 will cause the nut block 26 to move back and forth in a linear motion. The nut block 26 will drag the polishing wheel 28 to move back and forth while rotating through the protruding ring 29. In this way, the entire outer wall of the pipe can be polished. By starting the cylinder 24, the assembly plate 21 and the docking block 210 are pushed to move on the guide rail groove 211, thereby precisely controlling the distance of the polishing wheel 28 from the pipe and preventing the thickness of the pipe side wall from being polished unevenly.
