Description

Technical Field

[0001] The invention relates to the technical field of punching and clamping, in particular to a clamping structure for punching aluminum materials. Background Art

[0002] Aluminum is a material product made of aluminum and other alloy elements. The main metal element is aluminum, and some alloy elements are added to improve the performance of aluminum. Punching is the process of punching holes in aluminum through drilling equipment, so that the aluminum is processed to meet the standards of subsequent applications.

[0003] In the prior art, aluminum is punched mostly by drilling machines or other punching equipment. During the operation, in order to ensure the quality of the punching, the aluminum needs to be manually supported, which not only increases the labor intensity, but also causes a large impact on the aluminum during punching. During the punching process with manual support, shaking may occur, resulting in the aluminum punching being skewed. The quality of the aluminum punching needs to be improved. Summary of the invention

[0004] In order to improve the quality of aluminum punching, the present application provides a clamping structure for aluminum punching.

[0005] The present application provides a clamping structure for punching aluminum materials using the following technical solution: A clamping structure for punching aluminum materials comprises a base and a punching device, wherein the punching device is arranged on the base and used for punching, the base is provided with a fixed block, the fixed block is provided with a fixed groove, the base is provided with a first clamping block, the base is slidably provided with a second clamping block which can be inserted into the fixed groove, and the base is provided with a driving assembly, and the driving assembly is used to drive the second clamping block to move.

[0006] By adopting the above technical solution, the aluminum material to be punched is inserted into the fixed groove of the fixed block, and the driving component is started to mobilize the second clamping block to move. After the second clamping block enters the fixed groove, it continues to move, thereby pushing the aluminum material to be processed to move until the other side of the aluminum material abuts against the first clamping block. At this time, the first clamping block and the second clamping block respectively abut against the two sides of the aluminum material, thereby completing the clamping of the aluminum material. The punching equipment can be started to clamp the clamped aluminum material. Through mechanical clamping, the possibility of shaking and moving of the aluminum material when it is impacted by punching is reduced, thereby ensuring the efficiency of punching and reducing the possibility of damaging the sliding hole when punching the aluminum material, thereby improving the quality and stability of aluminum punching.

[0007] Preferably, the driving assembly includes a driving gear and a driving rack, the base is provided with a driving groove, the second clamping block is slidably arranged in the driving groove, the base is provided with a transmission groove communicated with the driving groove, the driving gear is rotatably arranged in the transmission groove, the driving rack is arranged on the second clamping block and inserted into the transmission groove and meshes with the transmission gear, the fixed block is slidably provided with a fixing rod, a transmission assembly is arranged between the fixing rod and the driving gear, and the transmission assembly is used to drive the driving gear to rotate.

[0008] By adopting the above technical solution, when the aluminum material to be processed is inserted into the fixed groove, the aluminum material pushes the fixed rod to slide, and drives the driving gear to rotate through the transmission assembly, thereby driving the driving rack to slide in the driving groove, so as to drive the second clamping block to slide and insert into the fixed groove to hold the aluminum material, thereby completing the clamping. The operation is simple and convenient. The action of installing and placing the aluminum material to be processed synchronously drives the second clamping block to slide for clamping, thereby simplifying the operation and improving the convenience of use.

[0009] Preferably, the base is provided with an assembly block, the assembly block is connected to the fixing block, the first clamping block is arranged on the assembly block, and the driving groove and the transmission groove are both arranged on the assembly block.

[0010] By adopting the above technical solution, an assembly block that is relatively connected and fixed to the fixed block is provided, thereby improving the stability of the movement of the second clamping block, and at the same time improving the stability of the first clamping block and the second clamping block in clamping the aluminum material, thereby reducing the possibility of overall shaking of the first clamping block and the second clamping block after clamping the aluminum material, thereby improving the stability and quality of the aluminum punching processing.

[0011] Preferably, the fixed block is provided with a fixing hole, the fixed rod is slidably arranged in the fixing hole and can be inserted into the fixing groove, the transmission assembly includes a first transmission rack, a second transmission rack and a transmission gear, the assembly block is provided with an assembly groove communicating with the transmission groove, the transmission gear is rotatably arranged in the transmission groove, the first transmission rack is slidably arranged in the assembly groove, the first transmission rack is connected to the fixed rod and inserted into the transmission groove to mesh with the transmission gear, the second transmission rack is slidably arranged in the transmission groove, the second transmission rack is meshed with the transmission gear, and the second transmission rack is meshed with the driving gear.

[0012] By adopting the above technical solution, the aluminum material to be processed is inserted into the fixing groove and the fixing rod is pushed to slide in the fixing hole. When the fixing rod slides, it drives the first transmission rack to move in the assembly groove, thereby driving the transmission gear to rotate, and then the second transmission rack is pushed to move in the transmission groove through meshing to drive the driving gear to rotate and realize transmission. Through the cooperation of the above transmission components, the action of installing the aluminum material is combined to push the second clamping block to move for clamping, thereby simplifying the overall operation steps and improving efficiency.

[0013] Preferably, a first assembly rod that can be abutted against a fixed rod is slidably arranged in the assembly groove, the first assembly rod can be inserted into the fixed hole, the first transmission rack is arranged on the first assembly rod, the base is provided with a sliding track, the assembly block is slidably arranged on the base, the assembly block is slidably connected to the fixed block, the base is provided with a moving cylinder, and the piston rod of the moving cylinder is connected to the assembly block.

[0014] By adopting the above technical scheme, when the aluminum material is inserted into the fixing groove, the fixing rod is pushed to move against the first assembly rod and the fixing rod is inserted into the assembly groove, so as to drive the second clamping block to move for clamping through the transmission component. When the punching is completed, the second clamping block is pushed to move, and the gear rack in the driving component and the transmission component are moved in coordination, so that the first assembly rod rises and pushes the fixing rod to rise, thereby pushing the aluminum material out of the fixing groove, thereby facilitating the removal of the aluminum material. At the same time, when no aluminum material is placed in the fixing, the fixing rod is located in the fixing hole, and the first assembly rod is located in the assembly groove. At this time, the assembly block can be pushed to move, so as to position the aluminum material at different positions according to different specifications of aluminum materials and different punching processing positions, thereby improving the stability of the processing position during aluminum processing, thereby further improving the stability and quality of aluminum processing, and at the same time, the assembly block is driven to move by a multi-stage moving cylinder, thereby simplifying the operation, and there is no need for the staff to manually push the assembly block to move, thereby reducing labor intensity and improving convenience of use.

[0015] Preferably, the assembly block is provided with a sliding groove which is in communication with the normal position, and the fixing block is inserted into the sliding groove and can slide in the sliding groove.

[0016] By adopting the above technical solution, the fixed block is inserted into the sliding groove of the assembly block, so that the fixed block and the assembly block slide relative to each other. At the same time, the fixed block is supported by the inner wall of the sliding groove, thereby reducing the possibility of shaking between the fixed block and the assembly block to ensure the quality of aluminum punching.

[0017] Preferably, the second clamping block is provided with a cover plate, and the cover plate is provided with a working groove.

[0018] By adopting the above technical solution, when the second clamping block moves to clamp the aluminum material, the cover plate covers the top of the aluminum material, thereby further limiting the aluminum material to improve the stability of the aluminum material during punching processing. At the same time, by setting the working groove, it is convenient for the punching equipment to process the aluminum material through the working groove, thereby improving the convenience of use.

[0019] Preferably, a second assembling rod is slidably arranged in the assembling groove, the first transmission rack is arranged on the second assembling rod, and an assembling spring is arranged between the first assembling rod and the second assembling rod.

[0020] By adopting the above technical solution, an assembly spring is arranged between the first assembly rod and the second assembly rod, thereby adding a certain buffer to the transmission process of the aluminum material being inserted into the fixing groove and the second clamping block moving. When the aluminum material pushes the fixing rod to move against the first assembly rod, the assembly spring is first compressed and then the second assembly rod is pushed to move by the elastic force of the assembly spring, thereby pushing the second clamping block to move through the rack and pinion of the transmission assembly and the drive assembly, so as to reduce the possibility that the aluminum material fails to move to the bottom of the fixing groove when the cover plate moves, causing the cover plate to get stuck with the aluminum material. At the same time, when the second clamping block is pushed to drive the aluminum material to rise, the buffering effect of the assembly spring is also used to reduce the possibility that the cover plate gets stuck with the aluminum material, thereby improving the convenience of use.

[0021] Preferably, the cover plate can be abutted against the first clamping block, the cover plate is provided with a first magnetic sheet, the first clamping block is provided with a second magnetic sheet, and the first magnetic sheet can be abutted against the second magnetic sheet and magnetically attracted.

[0022] By adopting the above technical solution, when the cover plate moves to cover the aluminum material, the cover plate adheres to the first clamping block, and the first magnetic sheet on the cover plate and the second magnetic sheet on the first clamping block adhere to and magnetically attract each other, thereby reducing the possibility of the second clamping block moving during the punching process of the aluminum material, thereby releasing the clamping and causing the aluminum material to shake, thereby reducing the possibility of punching failure due to the shaking of the aluminum material, thereby improving the stability and processing quality of the aluminum material processing.

[0023] Preferably, the first clamping block is rotatably provided with a first rotating wheel, the first rotating wheel is inserted into the fixing groove and abuts against the bottom wall of the fixing groove, and the second clamping block is rotatably provided with a second rotating wheel abuts against the bottom wall of the fixing groove.

[0024] By adopting the above technical solution, a first rotating wheel and a second rotating wheel are provided, thereby reducing the number of components for moving the assembly block, thereby facilitating the movement of the assembly block.

By setting a base, a punching device, a fixed block, a fixed groove, a first clamping block, a second clamping block and a driving assembly, the aluminum material to be processed is inserted into the fixed groove of the fixed block, and the second clamping block is driven to move on the base by the driving assembly, thereby driving the second clamping block to cooperate with the first clamping block to clamp the aluminum material to be processed. At this time, the punching device is used to punch the aluminum material. During the processing, the aluminum material is clamped by the first clamping block and the second clamping block and abuts against the bottom wall of the fixed groove, thereby reducing the possibility of shaking of the aluminum material, thereby reducing the possibility of damage to the aluminum material or the possibility of the punched hole being not formed during the processing, so as to improve the processing punching quality; 2. By setting an assembly block, a driving gear, a driving rack, a driving groove, a transmission groove, a fixing rod and a transmission component, when the aluminum material is inserted into the fixing groove, the fixing rod will be pushed to move in the fixing groove, thereby driving the driving gear to rotate in the transmission groove of the assembly hole through the transmission component between the fixing rod and the second clamping block, and then through the meshing of the gear rack, driving the driving rack to slide in the driving groove, so as to drive the second clamping block to slide in the driving groove following the driving rack, thereby driving the second clamping block to slide and cooperate with the first clamping block to clamp the aluminum material. At the same time, when the processing is completed, the second clamping block is pushed away from the aluminum material, thereby driving the driving gear to rotate through the movement of the driving rack. In this process, the rotation of the driving gear drives the fixing rod to move upward through the transmission component, thereby ejecting the processed aluminum material from the fixing groove, so as to facilitate the staff to take out the processed aluminum material, thereby improving the convenience of use; 3. By setting a fixing hole, a first transmission rack, a second transmission rack, a transmission gear and an assembly groove, when the aluminum material to be processed is inserted into the fixing groove, the aluminum material resists the fixing rod and pushes the fixing rod to move in the fixing hole, thereby driving the first transmission rack to move downward in the assembly groove, and driving the transmission gear to rotate in the transmission groove through meshing. The rotation of the transmission gear pushes the second transmission rack to slide in the transmission groove through meshing, thereby driving the driving gear in the transmission groove to rotate, so as to realize the transmission process. The operation is simple and convenient. In the process of installing the aluminum material into the fixing groove, a series of gear racks are used for transmission, thereby driving the second clamping block to move, thereby clamping the aluminum material, thereby improving the convenience of use.

The punching device 11 is used to punch aluminum materials through a drill bit. The base 1 is provided with a motor screw or other moving structure to drive the punching device 11 to move along the length direction of the base 1. The base 1 is provided with a frame 12, and a fixed block 121 is fixedly arranged on the frame 12. The fixed block 121 is provided with a fixed groove 122 that passes through the side walls on both sides along the length direction. The base 1 is provided with a sliding track 13 along the length direction. The sliding track 13 is arranged on both sides of the fixed block 121. Two assembly blocks 2 are slidably arranged on the sliding track 13. The assembly block 2 is provided with a sliding groove 24. The fixed block 121 is adapted to be inserted into the sliding groove 24 and can slide in the sliding groove 24. The fixing block 121 is fixedly provided with a first clamping block 3, which is inserted into the fixing groove 122. The assembly block 2 is provided with a driving groove 21, in which the second clamping block 4 is adapted to slide. The first clamping block 3 and the second clamping block 4 are located on both sides of the fixing block 121. The assembly block 2 is provided with a driving assembly 5 for driving the second clamping block 4 to move. The second clamping block 4 is driven to slide by the driving assembly 5, and the aluminum material is clamped in the fixing groove 122 with the cooperation of the first clamping block 3, thereby improving the stability of the aluminum material during punching processing, so as to improve the quality of the punching processing.

[0032] To improve the convenience of use, refer to Figure 2 and Figure 3The driving assembly 5 includes a driving gear 51 and a driving rack 52. A transmission groove 22 communicating with the driving groove 21 is provided inside the assembly block 2. The driving rack 52 is fixedly arranged on the bottom wall of the second clamping block 4 and inserted into the transmission groove 22 to mesh with the driving gear 51. The bottom wall of the fixing groove 122 is provided with a plurality of fixing holes 123 penetrating the bottom wall of the fixing block 121. A fixing rod 124 is slidingly arranged in the fixing hole 123 through a clamping block. The length of the fixing rod 124 is consistent with the length of the fixing hole 123. The assembly block 2 is provided with an assembly groove 23 communicating with the sliding groove 24 and the transmission groove 22. A first assembly rod 7 and a second assembly rod 71 are slidingly arranged in the assembly groove 23. An assembly spring 72 is connected between the first assembly rod 7 and the second assembly rod 71. The first assembly rod 7 is arranged above the second assembly rod 71 and can be inserted into the fixing hole 123 to abut against the fixing rod 124. A transmission assembly 6 for driving the driving gear 51 to rotate is provided between the second assembly rod 71 and the driving gear 51. Referring to the figure, the transmission assembly 6 includes a first transmission rack 62, a second transmission rack 63 and a transmission gear 61, the transmission gear 61 is rotatably arranged in the transmission groove 22, the first transmission rack 62 is fixedly arranged on the second assembly rod 71 and inserted into the transmission groove 22 to mesh with the transmission gear 61, the second transmission rack 63 is slidably arranged in the transmission groove 22, one end of the second transmission rack 63 is meshed with the transmission gear 61, and the other end of the second transmission rack 63 is meshed with the driving gear 51. In this embodiment, the diameter of the transmission gear is smaller than that of the driving gear, so the number of teeth of the driving gear is smaller than that of the transmission gear. Insert the aluminum material to be processed into the fixing groove 122, and push the fixing rod 124 to slide in the fixing hole 123 until the bottom wall of the fixing rod 124 is flush with the bottom wall of the fixing block 121. During this process, the fixing rod 124 pushes the first assembly rod 7 and compresses the assembly spring 72. At the same time, the assembly spring 72 recovers and pushes the second assembly rod 71 to slide, thereby driving the first transmission rack 62 to move, driving the transmission gear 61 to rotate, and then driving the driving gear 51 to rotate through the second transmission rack 63, so as to drive the driving rack 52 to move and drive the second clamping block 4 to move close to the first clamping block 3 for clamping. The operation is simple and convenient.

[0033] In order to further improve the stability of punching, refer to Figures 1 to 3, a cover plate 42 is fixedly provided on the side wall of the second clamping block 4 near the first clamping block 3, and a part of the bottom wall of the cover plate 42 can be fitted with the top wall of the first clamping block 3, a first magnetic sheet 422 is provided on the bottom wall of the cover plate 42, and a second magnetic sheet 32 ​​is provided on the top wall of the first clamping block 3, and the first magnetic sheet 422 can fit the second magnetic sheet 32 ​​and be magnetically attracted to the second magnetic sheet 32. A first rotating wheel 31 inserted into the fixed groove 122 is provided on the rotating sleeve of the first clamping block 3, and the first rotating wheel 31 is against the bottom wall of the fixed groove 122. A second rotating wheel 41 is provided on the rotating sleeve of the second clamping block 4, and the second rotating wheel 41 can be inserted into the fixed groove 122 and is against the bottom wall of the fixed groove 122. A moving cylinder 14 is fixedly provided on the side wall of the frame 12, and the piston rod of the moving cylinder 14 is fixedly connected to the assembly block 2. The moving cylinder 14 on the frame 12 is set in even number and is set at both ends of the fixed block 121, so as to improve the stability of the assembly block 2 when moving. The bottom wall side walls of the fixing rod 124 and the side walls of the assembly block are arranged as inclined surfaces that can fit together, so that the fixing rod 124 can be automatically pushed back into the fixing hole 123 during the movement of the assembly block 2, thereby reducing the possibility of the fixing rod 124 getting stuck in the assembly block 2 and improving the convenience of moving the assembly block 2. It can be arranged that when the second clamping block 4 moves close to the first clamping block 3 to clamp the aluminum material, the first magnetic sheet 422 will fit the second magnetic sheet 32 ​​and be adsorbed together, so that the cover plate 42 covers the aluminum material, thereby reducing the possibility of the aluminum material vibrating up and down, thereby further improving the stability of the punching and improving the punching quality.

[0034] The implementation principle of the clamping structure for punching aluminum materials in the embodiment of the present application is as follows: according to the length of the aluminum material to be punched, the moving cylinder 14 is started to push the assembly block 2 to move to a suitable position. During the movement, the fixing rod 124 needs to be manually pressed to make the first assembly rod 7 withdraw from the fixing hole 123, and the aluminum material is inserted into the fixing groove 122 and the fixing rod 124 inserted into the fixing groove 122 is pushed down in the fixing hole 123 until the bottom wall of the fixing rod 124 is flush with the bottom wall of the fixing block 121. In this process, the fixing rod 124 pushes the first assembly rod 7 to move and withdraw from the fixing hole 123. The first assembly rod 7 is compressed during the movement. Assemble the spring 72. After being compressed to a certain extent, the assembly spring 72 recovers and pushes the second assembly rod 71 downward, thereby driving the transmission gear 61 to rotate through the movement of the first transmission rack 62. The rotation of the transmission gear 61 pushes the second transmission rack 63 to move, thereby driving the drive gear 51 to rotate, and driving the drive rack 52 to rotate, thereby driving the second clamping block 4 to move close to the first clamping block 3, until the first clamping block 3 and the second clamping block 4 are against the aluminum material at both ends to complete the clamping, and at the same time, the cover plate 42 moves with the second clamping block 4 to cover the aluminum material, and the first magnetic sheet 422 attracts the second magnetic sheet 32 ​​to lock and fix it. At this time, the punching device 11 can be operated to punch the aluminum material through the working groove 421 on the cover plate 42. By clamping and fixing the aluminum material, the possibility of shaking during punching of the aluminum material is reduced to improve the stability and quality of the punching. When the punching is completed, the moving cylinder 14 can be started to push the assembly block 2 to move to change the clamping position, so as to clamp and punch other positions of the aluminum material. When the aluminum material is processed, the second clamping block 4 is manually pushed to separate the first magnetic sheet 422 and the second magnetic sheet 32, thereby driving the driving rack 52 to move, and the second transmission rack 63 is driven to move by the rotation of the driving gear 51, and the first transmission rack 62 and the second assembly rod 71 are driven to move by the rotation of the transmission gear 61. After the buffering effect of the assembly spring 72, the first assembly rod 7 and the fixing rod 124 are pushed upward to eject the aluminum material. When the aluminum material is ejected, the cover plate 42 is already away from the top of the aluminum material, so as to facilitate the removal of the processed aluminum material to improve the convenience of use.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
