Description

Technical Field

[0001] This utility model belongs to the field of grinding and processing technology, specifically an automatic burr grinding device for metal stamping parts. Background Technology

[0002] Burrs are extra, irregular protrusions or rough edges formed on the edges or surfaces of metal stamping parts during the stamping process due to material breakage and separation. They are one of the common defects in stamping processing, affecting not only the appearance quality of the parts but also potentially impacting subsequent processing, assembly, and performance. Therefore, burr removal is a critical post-processing step in the production of metal stamping parts. Existing burr grinding equipment requires placing the workpiece to be processed on the processing table, adjusting and fixing it, and then lowering the grinding equipment for grinding. This requires two steps: clamping and grinding, which affects the grinding efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an automatic burr grinding device for metal stamping parts, which solves the problem that existing burr grinding devices require the workpiece to be processed to be placed on the processing table and adjusted and fixed before the grinding device is lowered for grinding. This requires two steps, clamping and fixing and grinding, in sequence, which affects the grinding efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic burr removal device for metal stamping parts, comprising a processing base, electric telescopic rods symmetrically fixedly installed on both sides of the processing base, a top seat fixedly installed between the two electric telescopic rods, racks symmetrically fixedly installed at both ends of one side of the top seat, mounting blocks symmetrically fixedly connected to both sides of the processing base, with the mounting blocks located on one side of the electric telescopic rods, the racks slidingly connected inside the mounting blocks, a limit block fixedly installed at the bottom of the racks passing through the mounting blocks, a rotating gear meshing on one side of each rack, mounting plates symmetrically fixedly installed on both sides of the top of the processing base, a bidirectional screw fixedly installed between the two rotating gears, and the two ends of the bidirectional screw rotatably connected to the mounting plates via bearings, a T-slot provided on the top of the processing base, the position of the T-slot corresponding to the bidirectional screw, a limit baffle fixedly installed at the center position on one side of the T-slot on the top of the processing base, two clamping plates symmetrically threadedly connected to the surface of the bidirectional screw between the two mounting plates, a T-shaped slider fixedly installed at the bottom of the two clamping plates, and the T-shaped slider slidingly connected inside the T-slot.

[0005] As a further embodiment of this utility model: a mounting frame is fixedly installed at the bottom of the top seat, and two rolling wheels are rotatably connected to the inner walls of the mounting frame through bearings, with a polishing belt sleeved on the surface of the two rolling wheels.

[0006] As a further embodiment of this utility model: a mounting platform is fixedly installed on one side of the top seat, a motor is fixedly connected to the bottom of the mounting platform, and the output end of the motor is fixedly connected to one of the rolling wheels.

[0007] As a further embodiment of this utility model: the bottom of the processing seat is provided with a mounting base, and two guide rods are fixedly connected to both sides of the inner wall of the mounting base. Four connecting seats are fixedly installed on the bottom of the processing seat and the bottom of the mounting base, and the positions of the connecting seats and the guide rods correspond to each other.

[0008] As a further embodiment of this utility model: a damping ring is symmetrically slidably connected to the surface of the guide rod, and a second shock-absorbing spring is provided on the surface of the guide rod between the damping ring and the inner wall of the mounting base. The top and bottom of the damping ring are rotatably connected to a connecting rod by a pin, and the connecting rod is rotatably connected to the connecting seat by a pin.

[0009] As a further embodiment of this utility model: damping telescopic seats are fixedly connected to the top and bottom of the guide rod, and the two damping telescopic seats are fixedly connected to the processing seat and the mounting base, respectively. A shock-absorbing spring is provided on the surface of the damping telescopic seat.

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

[0011] 1. This automatic burr removal device for metal stamping parts, by setting a rack and rotating gear, places the workpiece on the processing seat and closes it to the limiting baffle. The top seat is controlled to move down so that the grinding belt is close to the workpiece surface. At this time, the rack moves down with the top seat, driving the rotating gear to rotate, so that the bidirectional screw rotates and moves the two clamping plates towards the limiting baffle. When the grinding belt is close to the workpiece surface, the two clamping plates fix the workpiece on the processing seat, thereby causing the top seat to move down and control the clamping plates to fix the workpiece to be processed, realizing the reduction of processing steps and improving processing efficiency.

[0012] 2. This automatic burr removal device for metal stamping parts, by setting up a damping telescopic seat and a damping ring, transmits the vibration generated by the processing seat to the damping telescopic seat and the connecting seat when the grinding belt is grinding. The damping telescopic seat presses down to deform the first damping spring, and the connecting seat pushes the damping ring to compress the second damping spring. When the first and second damping springs rebound, they lift the processing seat back to its original position. At the same time, the damping telescopic seat consumes the elastic potential energy of the first damping spring, and the damping ring slides on the surface of the guide rod to consume the elastic potential energy of the second damping spring, so that the processing seat gradually becomes stable, thereby achieving buffering of the device and avoiding the impact of vibration on the grinding effect on the workpiece.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an automatic burr removal device for metal stamping parts, including a processing base 1, electric telescopic rods 2 symmetrically fixedly installed on both sides of the processing base 1, a top seat 4 fixedly installed between the two electric telescopic rods 2, racks 3 symmetrically fixedly installed at both ends of one side of the top seat 4, mounting blocks 5 symmetrically fixedly connected to both sides of the processing base 1, and the mounting blocks 5 are located on one side of the electric telescopic rods 2, the racks 3 are slidably connected inside the mounting blocks 5, and the bottom of the racks 3 passes through the mounting blocks 5 and is fixedly installed with a limiting block 6. By providing the limiting block 6, when the racks 3 slide upward in the mounting blocks 5, the limiting block 6 prevents the racks 3 from detaching from the mounting blocks 5, so that the racks 3 will not move upward with the top seat 4 and detach from the mounting blocks 5, causing the device to malfunction.

[0019] Each rack 3 has a rotating gear 7 meshing on one side. Mounting plates 8 are symmetrically fixedly installed on both sides of the top of the machining base 1. A bidirectional screw 9 is fixedly installed between the two rotating gears 7, and the two ends of the bidirectional screw 9 are rotatably connected to the mounting plates 8 through bearings. The top of the machining base 1 is provided with a T-slot 12, and the position of the T-slot 12 corresponds to the bidirectional screw 9. A limiting baffle 13 is fixedly installed at the center of one side of the top of the machining base 1. Two clamping plates 10 are symmetrically threaded on the surface of the bidirectional screw 9 between the two mounting plates 8. A T-shaped slider 11 is fixedly installed at the bottom of the two clamping plates 10, and the T-shaped slider 11 slides through and is slidably connected inside the T-slot 12. With the bidirectional screw 9, the rotation of the bidirectional screw 9 causes the two clamping plates 10 to move synchronously towards the limiting baffle 13, thereby fixing the workpiece on the surface of the machining base 1.

[0020] A mounting bracket 16 is fixedly installed at the bottom of the top seat 4. Two rolling wheels 17 are rotatably connected to the inner walls of the mounting bracket 16 via bearings. A grinding belt 18 is fitted onto the surface of the two rolling wheels 17. A mounting platform 14 is fixedly installed on one side of the top seat 4. A motor 15 is fixedly connected to the bottom of the mounting platform 14. The output end of the motor 15 is fixedly connected to one of the rolling wheels 17. With the motor 15 and the grinding belt 18, when the motor 15 is working, it drives the rolling wheel 17 to rotate rapidly, so that the grinding belt 18 is close to the workpiece for grinding, enabling the device to quickly remove large-area burrs from the workpiece.

[0021] The bottom of the processing base 1 is provided with a mounting base 19. Two guide rods 20 are fixedly connected to both sides of the inner wall of the mounting base 19. Four connecting seats 23 are fixedly installed on the bottom of the processing base 1 and the bottom of the mounting base 19 respectively, and the positions of the connecting seats 23 and the guide rods 20 are corresponding. By providing the guide rods 20, the damping ring 21 is limited when sliding on the surface of the guide rods 20, ensuring that the damping ring 21 will not deviate when sliding on the surface of the guide rods 20.

[0022] A damping ring 21 is symmetrically slidably connected to the surface of the guide rod 20. A shock-absorbing spring 26 is provided on the surface of the guide rod 20 between the damping ring 21 and the inner wall of the mounting base 19. The top and bottom of the damping ring 21 are rotatably connected to a connecting rod 22 by a pin. The end of the connecting rod 22 away from the damping ring 21 is rotatably connected to the connecting seat 23 by a pin. With the connecting rod 22, when the vibration is transmitted to the connecting seat 23, the connecting seat 23 presses down on the connecting rod 22, and the connecting rod 22 pushes the damping ring 21 to slide on the surface of the guide rod 20, thereby achieving a buffering effect.

[0023] The top and bottom of the guide rod 20 are respectively fixedly connected to damping telescopic seats 24, and the two damping telescopic seats 24 are respectively fixedly connected to the bottom of the processing seat 1 and the top of the mounting base 19. The surface of the damping telescopic seat 24 is provided with a shock-absorbing spring 25. By providing the damping telescopic seat 24, when the shock-absorbing spring 25 returns to its original position, the damping telescopic seat 24 reduces the elastic potential energy of the shock-absorbing spring 25, so that the shock-absorbing spring 25 quickly tends to stabilize, thereby achieving the shock absorption effect.

[0024] The working principle of this utility model is as follows:

[0025] The workpiece to be processed is placed on the processing seat 1, so that the workpiece is close to the limiting baffle 13. The electric telescopic rod 2 is controlled to descend, so that the grinding belt 18 is close to the workpiece. When the electric telescopic rod 2 descends, it drives the rack 3 to move, so that the rotating gear 7 rotates. The bidirectional screw 9 is controlled to rotate, so that the two clamping plates 10 move inward to fix the workpiece. At this time, the grinding belt 18 is close to the surface of the workpiece. The motor 15 is started, so that the rolling wheel 17 rotates at high speed and drives the grinding belt 18 to run, grinding the burrs on the workpiece. The vibration generated by grinding is transmitted through the processing seat 1 to the damping telescopic seat 24 and the connecting seat 23. The connecting seat 23 presses down, so that the connecting rod 22 pushes the damping ring 21 to compress the mounting bracket 16. The damping telescopic seat 24 presses down, so that the shock-absorbing spring 25 is compressed. When the shock-absorbing spring 25 and the second shock-absorbing spring 26 rebound, the damping telescopic seat 24 and the damping ring 21 consume the elastic potential energy of the shock-absorbing spring 25 and the second shock-absorbing spring 26, so that the device quickly tends to stabilize, thereby stabilizing the quality of grinding.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
