A first motor is fixedly installed in front of the middle pulley and is coaxially installed. Support rods are arrayed behind the front table and slide in contact with the rear table.

[0007] This utility model further illustrates that: a second motor is fixedly installed at the front of the mounting box, and two sets of drive gears are installed inside the mounting box. The two sets of drive gears are meshed and installed. The drive gears are driven by the second motor. The drive gears are all installed parallel to the feeding wheel. The mounting box is symmetrically installed above the front table and the rear table.

[0008] The present invention further describes that: a feeding plate is fixedly installed on the top of both the front table and the rear table, and a conveying wheel is installed in the internal array of the feeding plate, and the conveying wheel is rotatably connected to the feeding plate.

[0009] The present invention further describes that: a base plate is installed parallel to the bottom of the upper plate, and a plate hole is provided through the interior of the base plate.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0011] (1) The first motor drives the two sets of pulleys at the rear to rotate. Then the two sets of pulleys drive the pulleys on both sides that are tensioned together by the transmission belt to rotate. After that, the pulleys drive the threaded rod to rotate. Since the threaded rod meshes with the front table, the front table will move back and forth under the action of the threaded rod, thereby adjusting the position between it and the rear table. During the translation, the support rod will maintain the stability between the front table and the rear table, and the base will support the front table to prevent the front table from tilting.

[0012] (2) By setting a hydraulic rod to drive the upper plate to move downward, the upper plate is limited to the position of lifting and lowering by a balance bar, and is placed at an angle. During the descent of the upper plate, the perforating needle is driven to pass through the inside of the plate hole. When the bottom plate contacts the cover, the upper plate will continue to descend to punch the cover. At this time, the upper plate compresses the spring. When the punching is completed and the plate is reset, the upper plate is slowly reset under the drive of the plate hole, which improves stability. Attached Figure Description

[0019] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] A punching device for automotive body panels, as shown in the figure, includes a base 1, a front table 2 mounted on top of the base 1, the front table 2 being slidably mounted to the base 1, two sets of threaded rods 6 being meshed inside the front table 2, and pulleys 3 being mounted at the ends of the two sets of threaded rods 6, mounting boxes 8 being fixedly mounted on the upper left and right ends of the front table 2, two sets of feeding wheels 11 being mounted parallel to the back of the mounting boxes 8, a rear table 7 being mounted behind the front table 2, the rear table 7 being mounted parallel to the front table 2, a rear support 22 being fixedly mounted on the top of the rear table 7, two sets of balance bars 15 being mounted below the rear support 22, hydraulic rods 17 being mounted parallel between the balance bars 15, an upper plate 16 being fixedly mounted on the bottom of the hydraulic rods 17, the balance bars 15 being mounted through the upper plate 16, and a perforating needle 18 being fixedly mounted on the bottom of the upper plate 16.

[0022] Four sets of pulleys 3 are installed in front of the base 1. Two sets of pulleys 3 are located in front of the threaded rod 6, and the remaining two sets of pulleys 3 are coaxially installed and located at the center line of the two sets of threaded rods 6. The two middle sets of pulleys 3 are installed parallel to each other and correspond to the positions of the two side pulleys 3 respectively. A transmission belt 4 is installed between each set of corresponding pulleys 3. A first motor 5 is fixedly installed in front of the middle pulley 3 and is coaxially installed. Support rods 14 are arranged in an array behind the front table 2. The support rods 14 slide between the rear table 7 and the first motor 5 during use. The two sets of pulleys 3 at the rear rotate, and then the two sets of pulleys 3 drive the pulleys 3 on both sides that are tensioned together by the transmission belt 4 to rotate. Then the pulleys 3 drive the threaded rod 6 to rotate. Since the threaded rod 6 meshes with the front table 2, the front table 2 will move back and forth under the action of the threaded rod 6, thereby adjusting the position between it and the rear table 7. During the translation, the support rod 14 will maintain the stability between the front table 2 and the rear table 7, and the base 1 will support the front table 2 to prevent the front table 2 from tilting.

[0023] Example 2

[0024] Similar to Embodiment 1, the difference is that a second motor 9 is fixedly installed at the front of the mounting box 8, and two sets of drive gears 10 are installed inside the mounting box 8. The two sets of drive gears 10 are meshed and driven by the second motor 9. The drive gears 10 are all installed parallel to the feeding wheel 11. The mounting box 8 is symmetrically installed above the front table 2 and the rear table 7. The second motor 9 drives the drive gears 10 inside the mounting box 8 to rotate. There are two drive gears 10 installed and they mesh with each other. Therefore, the two drive gears 10 will rotate in opposite directions. Then, the feeding wheel 11 behind the drive gear 10 will be driven to rotate synchronously. During the process of punching holes in the cover, the cover is clamped between the feeding wheels 11. The cover is moved by the rolling of the feeding wheels 11 to facilitate the adjustment of the punching position.

[0025] Example 2

[0026] Similar to Embodiment 1, the difference is that a feeding plate 12 is fixedly installed on the top of both the front table 2 and the rear table 7. The feeding plate 12 has a conveyor wheel 13 arranged in an array inside. The conveyor wheel 13 is rotatably connected to the feeding plate 12. The feeding plate 12 is installed on the top of both the front table 2 and the rear table 7. At the same time, multiple conveyor wheels 13 are rotatably connected inside. Therefore, during the conveying of the cover, the conveyor wheel 13 can reduce the friction between the cover and the ground, making the conveying convenient.

[0027] Example 2

[0028] Similar to Embodiment 1, except that a base plate 20 is installed parallel to the bottom of the upper plate 16, and a plate hole 21 is provided through the interior of the base plate 20. The plate hole 21 is aligned with the position of the perforating needle 18. A spring 19 is wound around the lower end of the balance bar 15, and the two ends of the spring 19 are fixed to the upper plate 16 and the base plate 20 respectively. In use, the hydraulic rod 17 drives the upper plate 16 to move downward. The upper plate 16 is limited in its lifting and lowering position by the balance bar 15, preventing it from tilting. During the descent of the upper plate 16, the perforating needle 18 passes through the plate hole 21. When the base plate 20 contacts the cover, the upper plate 16 continues to descend to punch a hole in the cover. At this time, the upper plate 16 compresses the spring 19. When the punching is completed and the plate is reset, the upper plate 16 slowly resets under the action of the plate hole 21, improving stability.

[0029] Working principle: First, the first motor 5 drives the two sets of pulleys 3 at the rear to rotate. Then, the two sets of pulleys 3 drive the pulleys 3 on both sides that are tensioned together by the transmission belt 4 to rotate. After that, the pulleys 3 drive the threaded rod 6 to rotate. Since the threaded rod 6 meshes with the front table 2, the front table 2 will move back and forth under the action of the threaded rod 6, thereby adjusting the position between it and the rear table 7. During the translation, the support rod 14 will maintain the stability between the front table 2 and the rear table 7, and the base 1 will support the front table 2 to prevent it from tilting. After adjusting the device to a suitable width, the cover plate that needs to be drilled is placed on it, and then the plate is clamped by the feeding wheel 11. Then, the hydraulic rod 17 drives the upper plate 16 to move downward. The upper plate 16 is limited by the balance rod 15. The upper plate 16 descends, tilting the upper plate 16 and driving the perforating needle 18 through the hole 21. When the bottom plate 20 contacts the cover, the upper plate 16 continues to descend to punch holes in the cover. At this time, the upper plate 16 compresses the spring 19. When the punching is completed and the upper plate 16 is reset, it slowly resets under the action of the hole 21. Finally, the second motor 9 drives the drive gear 10 inside the mounting box 8 to rotate. There are two drive gears 10 installed and they mesh with each other. Therefore, the two drive gears 10 will rotate in opposite directions. Then, the feeding wheel 11 behind the drive gear 10 will be driven to rotate synchronously. During the punching process of the cover, the cover is clamped between the feeding wheels 11. The rolling of the feeding wheels 11 drives the cover to move and adjust the punching position.
