Technical Field

[0001] This utility model relates to the field of metal stamping processing technology, and in particular to a burr removal device for metal stamping parts. Background Art

[0002] The burr removal device for metal stamping parts is mainly used to remove burrs generated during the stamping process, improve the surface quality of the product, and increase dimensional accuracy. Its function is to improve the appearance, performance and safety of the product, reduce problems in subsequent processing and assembly, and reduce production costs.

[0003] Existing deburring devices for metal stamping parts, such as the one disclosed in CN221891585U, involve setting up a worktable. An electric slide rail is fixedly connected to the top of the worktable's outer wall. A moving plate is slidably connected to the inner wall of the electric slide rail. A dust collection hood is fixedly connected to the bottom of the outer wall of the moving plate on the side away from the electric slide rail. An external pipe is provided on the outer wall of the dust collection hood. A clamping mechanism is provided on the inner wall of the worktable. Most existing deburring equipment, represented by this technology, primarily treats surface burrs. However, burrs may also be present inside the holes of the die, which existing devices struggle to remove by grinding, failing to meet actual production needs. Furthermore, removing burrs from metal stamping parts requires manual intervention for flipping, which is not only inefficient but also makes it difficult to guarantee the accuracy of the flipping adjustment, easily affecting the quality of the deburring process. Utility Model Content

[0004] The purpose of this invention is to solve the problems of difficulty in removing burrs from holes in metal stamping parts and inconvenience in adjusting the position and posture of metal stamping parts in the existing technology, and to propose a burr removal device for metal stamping parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A burr removal device for metal stamping parts includes a worktable and a grinder. The worktable is characterized by the following features: a fixed block is fixedly mounted on it; sliding rods are symmetrically fixedly mounted between two fixed blocks; mounting components are slidably fitted onto the two sliding rods; a displacement cylinder for pulling the mounting components is fixedly mounted on the fixed block; and a lifting cylinder with its output end fixedly connected to the grinder is fixedly mounted on the mounting component. A fixed plate is also fixedly mounted on the worktable, and a positioning assembly for fixing and flipping the metal stamping parts is mounted on the fixed plate.

[0007] Preferably, the positioning component includes a clamping mechanism disposed on the left rear of the fixed plate and used to clamp the metal stamping part, and the positioning component also includes a flipping mechanism disposed on the left front of the fixed plate and used to flip the metal stamping part. A trapezoidal limiting block is fixedly installed on the fixed plate, and a movable rod for fixing and connecting the clamping mechanism is movably sleeved between a pair of trapezoidal limiting blocks, and the flipping mechanism is installed on one end of the movable rod that passes through the trapezoidal limiting block.

[0008] Preferably, the clamping mechanism includes a clamping body fixedly sleeved on a movable rod, a clamping cylinder installed inside the clamping body, a driving component fixedly connected to the output end of the clamping cylinder, a pair of linkage components slidably sleeved on the upper part of the clamping body through symmetrically opened moving grooves, the driving component and the linkage components are movably connected by a trapezoidal long rectangular block and a trapezoidal long rectangular groove, and a clamping block for clamping metal stamping parts is fixedly connected to the linkage component by bolts.

[0010] Preferably, the drive block has a toothed groove that meshes with the toothed circular block.

[0011] Preferably, a connector is fixedly installed between the output end of the drive cylinder and the drive block.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1-4 A burr removal device for metal stamping parts includes a worktable 1 and a grinder 7. A fixing block 2 is fixedly installed on the worktable 1. Sliding round rods 3 are symmetrically fixedly installed between the two fixing blocks 2. Mounting parts 4 are slidably fitted on the two sliding round rods 3. A displacement cylinder 5 for pulling the mounting parts 4 is fixedly installed on the fixing block 2. A lifting cylinder 6 with its output end fixedly connected to the grinder 7 is fixedly installed on the mounting part 4. The grinder 7 can be moved in the left and right directions by setting the displacement cylinder 5, and the grinder 7 can be moved in the vertical direction by setting the lifting cylinder 6.

[0022] A fixing plate 8 is also fixedly installed on the workbench 1. A positioning assembly for fixing and flipping the metal stamping parts is installed on the fixing plate 8. The positioning assembly includes a clamping mechanism located on the left rear side of the fixing plate 8 for clamping the metal stamping parts. The clamping mechanism includes a clamping body 11 fixedly sleeved on the movable rod 10. A clamping cylinder 111 is installed inside the clamping body 11. A driving component 112 is fixedly connected to the output end of the clamping cylinder 111. A pair of linkage components 115 are slidably sleeved on the upper part of the clamping body 11 through symmetrically opened moving grooves 114. A trapezoidal groove is provided between the driving component 112 and the linkage component 115. The long rectangular block 113 and the trapezoidal long rectangular groove 116 are movably connected to realize the driving component 112 to pull the linkage component 115 to move. The linkage component 115 is fixedly connected to the clamping block 117 for clamping the metal stamping part by bolts. The clamping block 117 is used to directly clamp the metal stamping part. The output end of the clamping cylinder 111 drives the driving component 112 to move. The driving component 112 pushes and pulls the linkage component 115 to move. The linkage component 115 is slidably fitted in the moving groove 114. Therefore, a pair of linkage components 115 move towards each other and in opposite directions in the horizontal direction, thereby realizing the clamping block 117 clamping and releasing the metal stamping part.

[0023] The positioning assembly also includes a flipping mechanism located on the left front of the fixed plate 8 for flipping the metal stamping part. A trapezoidal limiting block 9 is fixedly installed on the fixed plate 8. A movable rod 10 for fixing and connecting the clamping mechanism is movably sleeved between a pair of trapezoidal limiting blocks 9. The trapezoidal limiting blocks 9 limit the movable rod 10, and the flipping mechanism is installed on one end of the movable rod 10 that passes through the trapezoidal limiting block 9. The flipping mechanism includes a toothed part that is fixedly sleeved on the movable rod 10 that movably passes through the trapezoidal limiting block 9. The circular block 12 rotates, thereby rotating the movable rod 10. A limiting groove 14 is vertically installed on the fixed plate 8, and a driving block 15 is slidably sleeved on the limiting groove 14. The driving block 15 has a toothed groove 151 that meshes with the circular block 12. A driving cylinder 13 is also installed on the fixed plate 8, which slides along the limiting groove 14 to pull the clamping mechanism to rotate. A connecting piece 16 is fixedly installed between the output end of the driving cylinder 13 and the driving block 15. When the driving cylinder 13 is activated, its output end moves through the driving connecting piece 16, thereby pulling the driving block 15, which is connected to the other end of the connecting block 16, to move. The movement of the toothed groove 151 pushes the meshing circular block 12 to rotate, thereby driving the driving cylinder 13, which in turn rotates the clamping mechanism fixedly connected to the movable rod 10.

[0024] It should be noted that the specific models and specifications of the displacement cylinder 5, lifting cylinder 6, grinder 7 and drive cylinder 13 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt the existing technology in this field, so they will not be elaborated here.

[0025] The functional principle of this utility model can be explained through the following operation methods:

[0026] First, place the metal stamping part between the clamping blocks 117, start the drive unit 112 until the clamping blocks 117 clamp the metal stamping part, and the drive unit 112 stops. Then start the drive cylinder 13. The connecting piece 16 fixedly connected to the output end of the drive cylinder 13 pulls the drive block 15 to move vertically along the limit slide groove 14, thereby driving the movable rod 10, which meshes with the toothed round block 12 and the toothed groove 151, to rotate until the side of the metal stamping part that needs to be polished faces the polisher 4. Then install the polisher 7 on the polisher 4, start the lifting cylinder 6 to adjust the height of the polishing part of the polisher 7 and the hole of the metal stamping part that needs to be polished to be consistent, and then start the displacement cylinder 5 to move left and right to drive the polisher 7 closer to the metal stamping part. At the same time, start the polisher 7 to polish the metal stamping part.

[0027] In the second step, after the burrs on one side of the metal stamping part are polished, the displacement cylinder 5 drives the polisher 7 away from the metal stamping part 7, and the drive cylinder 13 drives the movable rod 10 to pull the clamping body 11 to clamp the metal stamping part and flip it until the unpolished side faces the polisher 7. Then, the displacement cylinder 5 drives the polisher 7 to approach the metal stamping part and continue polishing it.

[0028] The third step is to complete the grinding of the metal stamping parts. The grinder 7 stops working. At the same time, the displacement cylinder 5 drives the grinder 7 away from the metal stamping parts 7, and the clamping cylinder 111 is started. The clamping cylinder 111 drives the drive component 112 to move vertically upward. The clamping blocks 117 move away from each other and release the metal stamping parts.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
