[0002] Grinding refers to grinding or rubbing the surface of a workpiece to make it smooth and refined. Grinding is usually required in the hardware processing process.

[0003] In some scenarios, individual hardware parts need to be polished independently according to requirements. The existing polishing method is usually manual polishing. The operator needs to place the hardware product directly in his hand and hold the polishing tool in the other hand to polish it. This kind of hardware polishing can easily cause operator fatigue, leading to unstable grip and thus easily causing safety accidents. In addition, the work is labor-intensive and has a high risk factor. Moreover, if there are requirements for the polishing angle, it is not easy to control the polishing angle manually.

The second clamping plate 20 and the first clamping plate 19 are used to clamp the guide rail 12. A clamping screw 32 is provided between the first clamping plate 19 and the second clamping plate 20. The clamping screw 32 is divided into two sections. One section is rotatably engaged with the first clamping plate 19, and the other section is threadedly engaged with the second clamping plate 20. A clamping motor 31 is fixed on the first clamping plate 19, and the clamping motor 31 is poweredly connected to the clamping screw 32.

[0030] In one embodiment, the two ends of the second roller 30 pass through the two guide rails 12 respectively and are rotatably engaged with the two sliding blocks 18 respectively.

[0031] Specifically, both the second roller 30 and the first roller 35 pass through the guide rail 12, and neither the first roller 35 nor the second roller 30 contacts the guide rail 12.

[0032] In one embodiment, a pointer 36 is fixed on the sliding block 18, and a scale line is provided on the guide rail 12, so that the pointer 36 can point to the scale line (not shown).

[0033] The pointer 36 indicates the scale line on the guide rail 12, so that the user can clearly know the current grinding angle.

[0034] In one embodiment, the clamping mechanism includes an elastic chuck 17, the outer side of which is provided with threads, and a threaded locking ring 27 is connected to the outer thread. The locking principle is the same as that of the threaded pipe elastic chuck disclosed in Chinese Utility Model No. CN87211366U.

[0035] Specifically, the flexible chuck 17 can be replaced according to the size of different hardware parts, and the flexible chuck can adapt to clamping hardware parts within a certain size range, thus improving its applicability.

[0036] In one embodiment, a sliding cavity 34 is provided in the middle of the bed 10, and a sliding plate 38 is slidably arranged in the sliding cavity 34.

[0040] Specifically, the stepper motor 14 can drive the entire clamping mechanism to move left and right, and the stepper motor 14 has a self-locking function, which facilitates the stability of the clamping during grinding.

[0041] In one embodiment, a control center 13 is provided on the bed 10. The control center 13 is used to control the operation of the entire device and can be operated by the user.

[0042] This application discloses a method for using a hardware grinding workbench. Hardware parts, such as nuts, are placed into the elastic chuck 17, and then the threaded locking ring 27 is rotated to clamp the hardware parts with the elastic chuck 17. The size of the elastic chuck 17 can be changed according to the size of the hardware parts. The replacement method is to remove the elastic chuck 17 from the rotating shaft 25, and then select a suitable elastic chuck 17 and insert it into the rotating shaft 25 through the insertion shaft 26 for fixation.

[0043] Then, control the hydraulic pump 22 to work, so that the hydraulic pump 22 drives the rotary motor 24 to rise, and the rotary motor 24 drives the rotary shaft 25 and the elastic chuck 17 to rise.

[0044] When adjusting the grinding angle, manually move the slide block 18 to make the pointer 36 indicate the appropriate scale line, then control the clamping motor 31 to work, making the clamping screw 32 rotate, thereby making the second clamping plate 20 close to the first clamping plate 19, so that the first clamping plate 19 and the second clamping plate 20 clamp the guide rail 12 and fix the grinding angle.

[0045] Then, by controlling the forward and reverse rotation of the stepper motor 14, the distance between the clamping mechanism and the sanding belt 29 is adjusted so that the hardware parts come into contact with the sanding belt 29.

[0046] If rotary grinding is required, the rotary motor 24 is controlled to work, so that the rotary motor 24 drives the rotary shaft 25 to rotate, and the rotary shaft 25 drives the elastic chuck 17 to rotate, thereby causing the hardware to rotate.
