Description

Technical Field

[0001] The utility model relates to the technical field of aluminum plate processing, and specifically relates to a precise positioning and punching device for aluminum plates. Background Technique

[0002] Aluminum veneer refers to a building decoration material formed by chromium plating and other treatments and then processed by fluorocarbon spraying technology. During its processing and production, punching operations need to be carried out by a punching machine.

[0003] A patent with the publication number of CN219746410U discloses an aluminum veneer punching machine, which relates to the technical field of aluminum veneer production. It includes a workbench. Four corners of the bottom end of the workbench are fixedly provided with support feet. One side of the top end of the workbench is fixedly provided with a guide plate. Both sides of the top end of the guide plate are fixedly provided with vertical plates. The top end of the guide plate is movably connected with a limiting plate. A limiting component is arranged between the two vertical plates. One side of the bottom end of the workbench is fixedly provided with two mounting plates. The beneficial effect of the utility model is that: when the blower operates, negative pressure is generated inside the dust collection box, so that the air flow on the surface of the workbench enters the inside of the dust collection box through the ventilation grooves. At the same time, the air flow can carry the metal chips on the surface of the workbench into the dust collection box, so as to facilitate the staff to collect and clean the metal chips that fall on its surface after the punching operation of the punching machine. Then, rotate the two mounting bolts and pull out the two clamping plates from the inner walls of the two clamping grooves respectively, so that the dust collection box can be disassembled to process the collected metal chips.

[0004] In the specific use process of the above-mentioned prior art, the second driving motor is started to drive the connecting lead screw to rotate. By rotating the connecting lead screw, the limiting plate can slide along the inner wall of the first sliding groove, and then one of the clamping plates can be used to push the aluminum veneer to move. When the two rubber pads are respectively in contact with both sides of the aluminum veneer, the aluminum veneer is fixed on the surface of the workbench through a plurality of return springs. When it is necessary to adjust the punching position of the aluminum veneer, the second driving motor is started to drive the connecting lead screw to continue rotating. At this time, a plurality of return springs contract to make the sliding plate slide into the inner wall of the second sliding groove, so as to facilitate the staff to adjust the punching position of the aluminum veneer. However, the above-mentioned structure for positioning the aluminum veneer has the problem of unstable positioning in actual use. Since the aluminum veneer is fixed on the surface of the workbench through a plurality of return springs, the extrusion force generated by the plurality of return springs cannot produce a rigid positioning for the aluminum veneer, and there is a situation of displacement during the punching process. And only the left and right sides of the aluminum veneer are positioned, and the aluminum veneer will move upward during punching. When punching multiple aluminum veneers of the same batch, it is necessary to reposition the aluminum veneer every time, which affects the processing efficiency of the aluminum veneer. In view of this, we propose a precise positioning and punching device for aluminum plates. Content of the Utility Model

[0005] The purpose of the utility model is to provide a precise positioning and punching device for aluminum plates to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions:

[0007] A precise positioning and punching device for aluminum plates, comprising a workbench. A punching assembly is provided on the top of the workbench. The punching assembly includes a U-shaped fixing plate. In the middle of the top of the U-shaped fixing plate, there is an electric telescopic rod. The movable rod of the electric telescopic rod passes through the top of the U-shaped fixing plate and is fixedly connected to a frame-shaped connecting frame. A motor is provided inside the frame-shaped connecting frame. The output shaft of the motor passes through the bottom of the inner wall of the frame-shaped connecting frame and is coaxially connected to a drill bit. The electric telescopic rod and the motor are both powered by an external power supply. When punching an aluminum plate, the motor drives the drill bit to rotate, and the electric telescopic rod drives the frame-shaped connecting frame to move downward, so that the drill bit moves towards the aluminum plate, and the drill bit punches the aluminum plate;

[0008] Two horizontally arranged strip holes which are symmetrically arranged left and right are formed on the top of the workbench. The two horizontally arranged strip holes are located between the left and right sides of the inner wall of the U-shaped fixing plate. Both of the two horizontally arranged strip holes are movably connected with side positioning assemblies. The two side positioning assemblies are symmetrically arranged left and right. The two side positioning assemblies can position the left and right sides of the aluminum plate to be punched, and can prevent the left and right displacement of the aluminum plate and prevent the aluminum plate from shifting upward during the punching process, thereby ensuring the punching quality of the aluminum plate;

[0009] The side positioning assembly includes a first L-shaped block. The bottom of the first L-shaped block is detachably connected to a first T-shaped base through a first bolt. The vertical part of the first T-shaped base is slidably connected in the horizontally arranged strip hole. The top of the horizontal part of the first T-shaped base is in contact with the bottom of the workbench. The bottom of the first L-shaped block is in contact with the top of the workbench;

[0010] A T-shaped slot is formed on the outer side of the vertical plate of the first L-shaped block. A T-shaped plug is inserted in the T-shaped slot. A rectangular side plate is provided on the side of the T-shaped plug away from the first L-shaped block. A strip-shaped top plate is provided on the side of the rectangular side plate away from the T-shaped plug. The T-shaped plug, the rectangular side plate and the strip-shaped top plate are integrally formed. When replacing aluminum plates with different thicknesses, the T-shaped plug, the rectangular side plate and the strip-shaped top plate can be replaced together, so that the strip-shaped top plate can position the top of the aluminum plate, thereby adapting to aluminum plates with different thicknesses;

[0011] Two first internally threaded fixing tubes are provided on the top of the horizontal plate of the first L-shaped block. Both of the two first internally threaded fixing tubes are threadedly connected with first pressing bolts. The threaded ends of the first pressing bolts are abutted against the top of the workbench, thereby fixing the position of the first L-shaped block, which is convenient for the staff to adjust the position of the side positioning assembly. The positions of the two side positioning assemblies can both be adjusted, so as to position the left and right sides of the aluminum plate and can be adjusted adaptively according to the punching position of the aluminum plate;

[0012] A longitudinal strip hole is provided at the top of the workbench and near the middle of the rear side edge. The longitudinal strip hole is movably connected with a limiting component. The limiting component includes a second L-shaped block. The bottom of the second L-shaped block is detachably connected with a second T-shaped base through a second bolt. The vertical part of the second T-shaped base is slidably connected in the longitudinal strip hole. The top of the horizontal part of the second T-shaped base is attached to the bottom of the workbench, and the bottom of the second L-shaped block is attached to the top of the workbench.

[0013] Two second internally threaded fixing tubes are provided at the top of the horizontal plate of the second L-shaped block. Both of the two second internally threaded fixing tubes are threadedly connected with second pressing bolts. The threaded ends of the second pressing bolts abut against the top of the workbench, thereby fixing the position of the second L-shaped block, facilitating the staff to adjust the position of the limiting component, enabling the second L-shaped block to limit the rear side of the aluminum plate. When the staff performs punching operations on the same batch of aluminum plates, since the positions of the limiting component and the two side positioning components have been confirmed, the staff only needs to push the aluminum plate backward between the two side positioning components until the rear side of the aluminum plate abuts against the limiting component to confirm the punching position of the aluminum plate, thereby improving the punching efficiency.

[0014] Preferably, an avoidance hole is provided at the top of the workbench and directly below the drill bit. When the drill bit punches the aluminum plate and passes through the aluminum plate, the drill bit can pass through the avoidance hole, thereby preventing the drill bit from damaging the workbench.

[0015] Preferably, a waste box is placed below the workbench. The waste box is located directly below the avoidance hole and is used to receive the waste generated during the punching operation.

[0016] Preferably, two positioning vertical rods arranged symmetrically left and right are provided at the top of the frame-shaped connecting frame. The tops of the two positioning vertical rods penetrate through the top of the inner wall of the U-shaped fixing plate to the outside, improving the stability when the frame-shaped connecting frame moves up and down.

[0017] Preferably, a first rubber pad is provided on the side surface of the rectangular side plate and below the strip-shaped top plate to prevent the side surface of the aluminum plate from being worn.

[0018] Preferably, a second rubber pad is provided at the bottom of the strip-shaped top plate to prevent the top edge of the aluminum plate from being worn.

[0019] Preferably, a third rubber pad is provided on the front side of the vertical plate of the second L-shaped block to prevent the rear side of the aluminum plate from being worn.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] 1. For this precise positioning and drilling device for aluminum plates, when drilling the aluminum plate, the motor drives the drill bit to rotate, and the electric telescopic rod drives the frame-shaped connecting frame to move downward, so that the drill bit moves towards the aluminum plate and drills the aluminum plate.

[0022] 2. For this precise positioning and drilling device for aluminum plates, the two side positioning components can position the left and right sides of the aluminum plate to be drilled, and can prevent the left and right displacement of the aluminum plate and prevent the aluminum plate from shifting upward during drilling, thus ensuring the drilling quality of the aluminum plate.

[0023] 3. For this precise positioning and drilling device for aluminum plates, the T-shaped plug, rectangular side plate and strip-shaped top plate are integrally formed. When replacing aluminum plates of different thicknesses, the T-shaped plug, rectangular side plate and strip-shaped top plate can be replaced together, so that the strip-shaped top plate can position the top of the aluminum plate, thus adapting to aluminum plates of different thicknesses.

[0024] 4. For this precise positioning and drilling device for aluminum plates, the threaded end of the first compression bolt abuts against the top of the workbench, thereby fixing the position of the first L-shaped block, facilitating the staff to adjust the position of the side positioning component. The positions of the two side positioning components can both be adjusted to position the left and right sides of the aluminum plate, and can be adjusted adaptively according to the drilling position of the aluminum plate.

[0025] 5. For this precise positioning and drilling device for aluminum plates, the threaded end of the second compression bolt abuts against the top of the workbench, thereby fixing the position of the second L-shaped block, facilitating the staff to adjust the position of the limiting component, so that the second L-shaped block plays a role in limiting the rear side of the aluminum plate. When the staff drills the same batch of aluminum plates, since the positions of the limiting component and the two side positioning components have been confirmed, the staff only needs to push the aluminum plate backward between the two side positioning components until the rear side of the aluminum plate abuts against the limiting component to confirm the drilling position of the aluminum plate, thus improving the drilling efficiency.

[0035] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0036] An accurate positioning and drilling device for aluminum plates, comprising a workbench 1. At the top of the workbench 1, there is a drilling assembly 2. The drilling assembly 2 includes a U-shaped fixing plate 20. In the middle of the top of the U-shaped fixing plate 20, there is an electric telescopic rod 21. The movable rod of the electric telescopic rod 21 passes through the top of the U-shaped fixing plate 20 and is fixedly connected to a frame-shaped connecting frame 22. Inside the frame-shaped connecting frame 22, there is a motor 23. The output shaft of the motor 23 passes through the bottom of the inner wall of the frame-shaped connecting frame 22 and is coaxially connected to a drill bit 24. Both the electric telescopic rod 21 and the motor 23 are powered by an external power source. When drilling an aluminum plate, the motor 23 drives the drill bit 24 to rotate, and the electric telescopic rod 21 drives the frame-shaped connecting frame 22 to move downward, so that the drill bit 24 moves towards the aluminum plate, and the drill bit 24 drills the aluminum plate;

[0037] On the top of the workbench 1, there are two horizontally arranged strip holes 11 that are symmetrically arranged left and right. The two horizontally arranged strip holes 11 are located between the left and right sides of the inner wall of the U-shaped fixing plate 20. Both of the two horizontally arranged strip holes 11 are movably connected with side positioning components 3. The two side positioning components 3 are symmetrically arranged left and right. The two side positioning components 3 can position the left and right sides of the aluminum plate to be drilled, and can prevent the left and right displacement of the aluminum plate, and prevent the aluminum plate from shifting upward during the drilling process, so as to ensure the drilling quality of the aluminum plate;

[0038] The side positioning component 3 includes a first L-shaped block 30. The bottom of the first L-shaped block 30 is detachably connected to a first T-shaped base 32 through a first bolt 31. The vertical part of the first T-shaped base 32 is slidably connected in the horizontally arranged strip hole 11. The top of the horizontal part of the first T-shaped base 32 is in contact with the bottom of the workbench 1. The bottom of the first L-shaped block 30 is in contact with the top of the workbench 1;

[0039] On the outer side of the vertical plate of the first L-shaped block 30, there is a T-shaped slot 300. A T-shaped plug 33 is inserted in the T-shaped slot 300. On the side of the T-shaped plug 33 away from the first L-shaped block 30, there is a rectangular side plate 34. On the side of the rectangular side plate 34 away from the T-shaped plug 33, there is a strip-shaped top plate 35. The T-shaped plug 33, the rectangular side plate 34 and the strip-shaped top plate 35 are integrally formed. When replacing aluminum plates of different thicknesses, the T-shaped plug 33, the rectangular side plate 34 and the strip-shaped top plate 35 can be replaced together, so that the strip-shaped top plate 35 can position the top of the aluminum plate, so as to adapt to aluminum plates of different thicknesses;

[0040] On the top of the horizontal plate of the first L-shaped block 30, there are two first internally threaded fixing tubes 38. Both of the two first internally threaded fixing tubes 38 are threadedly connected with first pressing bolts 39. The threaded ends of the first pressing bolts 39 abut against the top of the workbench 1, thereby fixing the position of the first L-shaped block 30, facilitating the staff to adjust the position of the side positioning assembly 3. The positions of the two side positioning assemblies 3 can both be adjusted, so as to position the left and right sides of the aluminum plate, and can be adaptively adjusted according to the punching positions of the aluminum plate;

[0041] At the top of the workbench 1 and near the middle of the rear side edge, there is a longitudinal strip hole 12. The longitudinal strip hole 12 is movably connected with a limiting assembly 4. The limiting assembly 4 includes a second L-shaped block 40. The bottom of the second L-shaped block 40 is detachably connected with a second T-shaped base 42 through a second bolt 41. The vertical part of the second T-shaped base 42 is slidably connected in the longitudinal strip hole 12. The top of the horizontal part of the second T-shaped base 42 is attached to the bottom of the workbench 1, and the bottom of the second L-shaped block 40 is attached to the top of the workbench 1;

[0042] On the top of the horizontal plate of the second L-shaped block 40, there are two second internally threaded fixing tubes 44. Both of the two second internally threaded fixing tubes 44 are threadedly connected with second pressing bolts 45. The threaded ends of the second pressing bolts 45 abut against the top of the workbench 1, thereby fixing the position of the second L-shaped block 40, facilitating the staff to adjust the position of the limiting assembly 4, so that the second L-shaped block 40 plays a role in limiting the rear side of the aluminum plate. When the staff performs punching operations on the same batch of aluminum plates, since the positions of the limiting assembly 4 and the two side positioning assemblies 3 have been confirmed, the staff only needs to push the aluminum plate backward between the two side positioning assemblies 3 until the rear side of the aluminum plate abuts against the limiting assembly 4 to confirm the punching position of the aluminum plate, thereby improving the punching efficiency.

[0043] In this embodiment, at the top of the workbench 1 and directly below the drill bit 24, there is an avoidance hole 10. When the drill bit 24 punches the aluminum plate and passes through the aluminum plate, the drill bit 24 can pass through the avoidance hole 10, thereby preventing the drill bit 24 from damaging the workbench 1.

[0044] Specifically, a waste box 5 is placed below the workbench 1. The waste box 5 is located directly below the avoidance hole 10. The waste box 5 is used to receive the waste generated by the punching operation.

[0045] Furthermore, on the top of the frame-shaped connecting frame 22, there are two positioning vertical rods 25 arranged symmetrically left and right. The tops of the two positioning vertical rods 25 both penetrate through the top of the inner wall of the U-shaped fixing plate 20 to the outside, improving the stability when the frame-shaped connecting frame 22 moves up and down.

[0046] Furthermore, on the side surface of the rectangular side plate 34 and below the strip-shaped top plate 35, there is a first rubber pad 36 to prevent the side surface of the aluminum plate from being worn.

[0047] Furthermore, a second rubber pad 37 is provided at the bottom of the strip-shaped top plate 35 to prevent the top edge of the aluminum plate from being worn.

[0048] Furthermore, a third rubber pad 43 is provided on the front side of the vertical plate of the second L-shaped block 40 to prevent the rear side of the aluminum plate from being worn.

[0049] When the aluminum plate precise positioning and punching device of this embodiment is in use, the staff places the aluminum plate to be punched on the workbench 1, making the position to be punched on the aluminum plate directly below the drill bit 24. Then, the staff makes the right side of the first rubber pad 36 of the left and side positioning assembly 3 fit against the left side of the aluminum plate, and tightens the two second pressing bolts 45 to fix the position of the left and side positioning assembly 3. Then, the staff makes the left side of the first rubber pad 36 of the right and side positioning assembly 3 fit against the right side of the aluminum plate, and tightens the two second pressing bolts 45 to fix the position of the right and side positioning assembly 3. At this time, the strip-shaped top plates 35 of the two side positioning assemblies 3 play a positioning role on the top of the aluminum plate. Then, the staff makes the front side of the third rubber pad 43 of the limiting assembly 4 fit against the rear side of the aluminum plate to play a limiting role on the rear side of the aluminum plate. After that, the staff starts the electric telescopic rod 21 and the motor 23 to work. The motor 23 drives the drill bit 24 to rotate, and the electric telescopic rod 21 drives the frame-shaped connecting frame 22 to move downward, so that the drill bit 24 moves towards the aluminum plate, and the drill bit 24 punches the aluminum plate. The waste generated by punching falls from the avoidance hole 10 into the waste box 5; when the staff punches the same batch of aluminum plates, since the positions of the limiting assembly 4 and the two side positioning assemblies 3 have been confirmed, the staff only needs to push the aluminum plate backward between the two side positioning assemblies 3 until the rear side of the aluminum plate abuts against the limiting assembly 4 to confirm the punching position of the aluminum plate, thereby improving the punching efficiency; when punching aluminum plates of different thicknesses, the staff takes out the T-shaped plug 33 in the side positioning assembly 3 from the T-shaped slot 300, and replaces the T-shaped plug 33, the rectangular side plate 34 and the strip-shaped top plate 35 together, so that the new strip-shaped top plate 35 can position the top of the next batch of aluminum plates, thereby adapting to aluminum plates of different thicknesses.

Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
