A processing surface is provided on one side of the substrate, and at least two positioning posts are provided on the processing surface. The positioning posts are adapted to the first through holes on the first product to be processed. A second through hole matching the positioning posts is provided on the first pressing plate. The first pressing plate is located above the first product to be processed. A number of positioning grooves are provided on the substrate, and the positioning grooves are located on one side of the processing surface. A second product to be processed is provided in the positioning grooves. The second product to be processed is in contact with the surface of the first product to be processed, and the side surface of the first pressing plate abuts against the side surface of the second product to be processed.

When the hardware parts need multi-sided processing such as outer surface grinding, the clamping device is likely to interfere with the operation. Workers need to hold the hardware parts by hand for grinding, which is easy to be scratched by the grinding machine, and the safety level is not high. In view of this, we propose a hardware part processing positioning device. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] A hardware processing positioning device is a device used to ensure the precise placement of parts during metal processing. During hardware processing, multi-sided processing or rotational positioning of workpieces is usually involved.

[0023] Please refer to Figures 1 - 3 As shown, this embodiment provides a hardware part processing positioning device, including a base 1. In order to ensure that the outer surface processing of the hardware part 11 is not affected by the positioning device, specifically as follows: A slide groove 111 is opened on the right side of the top of the base 1, and a slide block 221 is slidably connected to the inner wall of the slide groove 111. The top of the slide block 221 is fixedly connected to a mounting plate 22. The left end of the rotating rod 215 is rotatably connected to the left side of the mounting plate 22. A threaded rod 212 is provided on the left side of the rotating rod 215. A ring block 211 is threadedly connected to the outer surface of the threaded rod 212. The outer surface of the ring block 211 is rotatably connected to a support plate 21. The outer surface of the support plate 21 is rotatably connected to a connecting plate 217. The left side of the connecting plate 217 is rotatably connected to a T-shaped block 2. The inner outer surface of the T-shaped block 2 is rotatably connected to a rotating plate 234. The inner outer surface of the rotating plate 234 is rotatably connected to a rotating shaft 231. The end of the rotating shaft 231 is rotatably connected to the end of a circular plate 23. The other end of the circular plate 23 is rotatably connected to the end of the threaded rod 212. The ring block 211 moves along the length direction of the threaded rod 212. However, in the existing hardware part 11 processing positioning devices, most of them clamp and fix from the outside of the hardware part 11. When the hardware part 11 needs multi-sided processing such as outer surface grinding, the clamping device is likely to interfere with the operation. Workers need to hold the hardware part 11 for grinding, which is likely to be scratched by the grinding machine, and the safety level is not high.

[0024] The improvement of this embodiment lies in:

[0025] First, the rotation of the handle 216 drives the rotation of the rotating rod 215. Then, the rotation of the rotating rod 215 drives the rotation of the fixed block 214. Immediately afterwards, the rotation of the fixed block 214 drives the rotation of the threaded rod 212. And the rotation of the threaded rod 212 drives the annular block 211 to move left and right on the threaded rod 212. Immediately afterwards, it drives the rotation of the rotating plate 234 and the support plate 21 by an angle. By changing the angles of the rotating plate 234 and the support plate 21, the T-shaped block 2 can fix hardware parts 11 of different sizes. And the hardware parts 11 are convenient to install and remove, improving the scope of application.

[0026] To facilitate the rotation of the rotating rod 215, therefore, the handle 216 is rotatably connected to the right side of the mounting plate 22. The end of the handle 216 extends into the mounting plate 22 and is fixedly connected to the end of the rotating rod 215. The rotation of the handle 216 drives the rotation of the rotating rod 215, realizing the convenience of the rotation of the rotating rod 215.

[0027] To facilitate the removal of the hardware part 11, therefore, a hole groove 213 is formed at the end of the threaded rod 212. The other end of the rotating rod 215 is fixedly connected to a fixed block 214. The fixed block 214 is inserted into the hole groove 213. First, the mounting plate 22 is moved to the right to pull the fixed block 214 out of the hole groove 213, realizing the convenience of removing the hardware part 11.

[0028] Secondly, to facilitate the rotation of the rotating shaft 231, therefore, the other end of the rotating shaft 231 is fixedly connected to the end of the motor 232. The rotation of the motor 232 drives the rotation of the rotating shaft 231, realizing the convenience of the rotation of the rotating shaft 231 and improving the degree of automation.

[0029] Considering that the motor 232 is unstable when suspended, therefore, a support plate 233 is fixedly connected to the other end of the motor 232. The bottom of the support plate 233 is fixedly connected to the top left side of the base 1. First, the base 1 fixes the support plate 233, and then the motor 232 is fixed through the support plate 233, realizing the stability of the motor 232 without suspension.

[0030] In summary, the working principle of this solution is as follows:

[0031] By manually turning the handle 216, the rotation of the handle 216 drives the rotating rod 215 to rotate, and then the rotating rod 215 drives the fixing block 214 to rotate, and then the fixing block 214 rotates to drive the threaded rod 212 to rotate, and the rotation of the threaded rod 212 drives the annular block 211 to move rightward on the threaded rod 212, and then drives the rotating plate 234 and the support plate 21 to increase the angle, and the distance between the T-shaped block 2 and the threaded rod 212 becomes closer. The mounting plate 22 is held and pulled to the right, so that the slider 221 drives the mounting plate 22 to move to the right in the slide groove 111, and the fixing block 214 is pulled out of the hole groove 213. The hardware 11 is held and put on the T-shaped block 2, and the mounting plate 22 is manually pulled to the left, and the fixing block 214 is inserted into the hole groove 213. The handle 216 is manually turned, and the rotating rod 215 is driven to rotate by the rotation of the handle 216, and then The rotation of the rear rotating rod 215 drives the fixed block 214 to rotate, and then the rotation of the fixed block 214 drives the threaded rod 212 to rotate, and the rotation of the threaded rod 212 drives the annular block 211 to move leftward on the threaded rod 212, and then drives the rotating plate 234 and the support plate 21 to become smaller, so that the outer surface of the T-shaped block 2 is clamped with the inner surface of the hardware 11, so that the hardware 11 is fixed and does not move, and the hardware 11 will not shake during grinding, resulting in grinding failure and inaccuracy. At this time, the motor 232 is connected to the power supply, and the rotation of the motor 232 drives the rotating shaft 231 to rotate, and the rotation of the rotating plate 234 and the T-shaped block 2 drives the hardware 11 to rotate, which is more convenient for grinding. The hardware 11 is not shaken and the grinding is more accurate. It is very convenient to take the hardware 11, and there is no obstruction on the outer surface of the hardware 11, which is more convenient for grinding, increasing the scope of application and improving safety.
