[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This burr-removing device for processing hardware parts, by setting up a servo motor, a first bevel gear, a second bevel gear, and clamping springs, firstly places the hardware parts onto the worktable, at which point the hardware parts can be positioned and clamped. By controlling the servo motor to drive the first bevel gear, the second bevel gear, and the threaded rod to rotate, the threaded rod drives the sliding blocks to slide on the sliding rod, so that the four sliding blocks simultaneously drive the mounting block and clamping block to approach the hardware parts. When the clamping block contacts the hardware parts, the clamping block will squeeze the elastic telescopic rod and the clamping spring. The elasticity of the elastic telescopic rod and the clamping spring is used for buffering, so that the clamping block flexibly clamps the hardware parts. When all four clamping blocks contact the hardware parts at the same time, the hardware parts are fixed in the center position of the worktable. By clamping the hardware parts with four clamping blocks at the same time, the clamping and fixing effect is better, so that the workpiece will not fall during grinding, reducing the need for manual handling of the workpiece and improving safety.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a burr-removing device for processing hardware accessories, including a base 1, a servo motor 2 fixedly connected to the bottom center of the base 1, and a worktable 15 fixedly connected to the top center of the base 1. The worktable 15 is set on the top of the base 1, and the clamping block 14 and the mounting block 10 are L-shaped. This arrangement allows the clamping block 14 to penetrate into the center of the worktable 15, and can clamp and fix the hardware accessories at the center of the worktable 15.

[0020] The output end of the servo motor 2 is fixedly connected to the first bevel gear 3. The base 1 has a mounting groove 8 corresponding to the position of the first bevel gear 3. The first bevel gear 3 is rotatably connected to the mounting groove 8 through a bearing. The top of the first bevel gear 3 is meshed with a second bevel gear 4. There are four second bevel gears 4. By setting the first bevel gear 3 and the second bevel gear 4, the servo motor 2 is started to drive the first bevel gear 3 to rotate. Then, the first bevel gear 3 synchronously drives the four second bevel gears 4 to rotate, thereby causing the second bevel gears 4 to drive the threaded rod 6 to rotate, so that the threaded rod 6 can drive the sliding block 7 to move.

[0021] A threaded rod 6 is fixedly connected to one side of the second bevel gear 4. A sliding groove 5 is provided on the top of the base 1 corresponding to the position of the threaded rod 6. The two ends of the threaded rod 6 are rotatably connected to the inner wall of the sliding groove 5 through bearings. A sliding block 7 is threadedly connected through the external thread of the threaded rod 6. A sliding rod 9 is slidably connected through both sides of the sliding block 7. The two ends of the sliding rod 9 are fixedly connected to the sliding groove 5. With the setting of the sliding rod 9, when the sliding block 7 is driven to move by the rotating threaded rod 6, the sliding block 7 slides on the surface of the sliding rod 9 at the same time. The sliding rod 9 limits the sliding block 7 to prevent the sliding block 7 from deflecting.

[0022] A mounting block 10 is fixedly connected to the top of the sliding block 7. A connecting groove 11 is provided in the mounting block 10. An elastic telescopic rod 12 is fixedly connected in the connecting groove 11. A clamping block 14 is fixedly connected to one end of the elastic telescopic rod 12. The clamping block 14 is slidably connected in the connecting groove 11. A clamping spring 13 is sleeved on the outer arc surface of the elastic telescopic rod 12. With the setting of the elastic telescopic rod 12 and the clamping spring 13, when the clamping block 14 clamps the material, the elastic telescopic rod 12 and the clamping spring 13 are compressed at the same time. The elastic force of the elastic telescopic rod 12 and the clamping spring 13 is used for buffering, so that the clamping block 14 can perform flexible clamping, preventing the clamping block 14 from damaging the hardware accessories, and improving the clamping effect.

[0023] Electric telescopic plates 16 are fixedly connected to both sides of the base 1. The top of the two electric telescopic plates 16 is fixedly connected to the same top plate 17. With the setting of the electric telescopic plates 16, when it is necessary to polish the hardware parts, the electric telescopic plates 16 are raised and lowered, thereby driving the top plate 17 and the polishing disc 20 to move to a suitable height to polish the hardware parts.

[0024] A motor protective shell 18 is fixedly connected to the top of the top plate 17. A grinding motor 19 is fixedly connected inside the motor protective shell 18. A grinding disc 20 is fixedly connected to the output end of the grinding motor 19. The grinding disc 20 is rotatably connected to the bottom of the top plate 17. The position of the grinding disc 20 corresponds to the worktable 15. By setting up the grinding motor 19 and the grinding disc 20, the grinding motor 19 is started, and the grinding disc 20 is rotated by the grinding motor 19, so that the grinding disc 20 can grind the hardware parts.

[0025] The working principle of this utility model is as follows: First, the hardware parts are placed on the workbench 15. After placement, the servo motor 2 can be started. The output end of the servo motor 2 drives the first bevel gear 3 to rotate. The first bevel gear 3 drives the second bevel gear 4 and the threaded rod 6 to rotate. When the threaded rod 6 rotates, it drives the sliding block 7 to move. At the same time, the sliding block 7 slides on the slide rod 9, so that the four sliding blocks 7 simultaneously drive the mounting block 10 and the clamping block 14 to approach the hardware parts. When the clamping block 14 contacts the hardware parts, the clamping block 14 will be in the connecting groove 11. The internal sliding clamping block 14 simultaneously presses the elastic telescopic rod 12 and the clamping spring 13, using the elastic force of the elastic telescopic rod 12 and the clamping spring 13 for buffering. The four clamping blocks 14 fix the hardware parts in the center position of the worktable 15. At this time, the grinding motor 19 can be started, and the grinding disc 20 can be rotated by the grinding motor 19. At this time, the electric telescopic plate 16 can be started, and the top plate 17 and the grinding disc 20 can be lowered by the electric telescopic plate 16, so that the grinding disc 20 can move and fit against the hardware parts, thereby grinding the hardware parts.
