A reinforcing clamping device for a thin aluminum piece of a sound box

Abstract

This utility model discloses a device for reinforcing and clamping thin aluminum parts for speakers, relating to the field of speaker technology. It includes a hollow base with support frames on both sides of the top of the hollow base. An adjustment structure is provided between the two support frames. The two pressing platforms can clamp and reinforce the thin aluminum parts placed on the two support frames. Because a rubber anti-slip pad is installed on one side of the bottom of the pressing platform, the friction between the pad and the thin aluminum parts is increased, thereby improving the stability of the fixation and preventing the thin aluminum parts from sliding during processing. This process only requires rotating the second handle to clamp and reinforce the thin aluminum parts, making the operation simple and convenient, improving the efficiency of the reinforcement and clamping. It solves the problem in the prior art that two tension screws need to be rotated to press the two pressing plates against the thin sheet, which is inconvenient, increases the number of steps, seriously affects the reinforcement and clamping process, and reduces the practicality of the device.

Description

Technical Field

[0001] This utility model relates to the field of speaker technology, specifically a speaker thin aluminum sheet reinforcement clamping device. Background Technology

[0002] In the speaker manufacturing process, the processing and assembly of thin aluminum parts is a crucial step.

[0003] In the prior art, patent announcement number CN211841612U discloses a metal sheet tooling fixture, including a base, a guide rail, a positive and negative threaded rod, and a fixture seat. The fixture seat includes a sliding seat, a pressing plate, and a tensioning rod. Two fixture seats are provided, each screwed to the positive and negative threads of the positive and negative threaded rods, respectively. The upper surfaces of the two sliding seats have recesses close to each other, and the lower surfaces of the two pressing plates have protrusions matching the recesses. By setting the positive and negative threaded rods, the width of the two fixture seats can be adjusted simultaneously with one hand; by setting corresponding recesses and protrusions on the sliding blocks and pressing plates, the position of the metal sheet can be positioned to prevent lateral displacement; by setting the tensioning rod to adjust the position of the pressing plate, the metal sheet can be quickly replaced and moved.

[0004] While the above solution can clamp the sheet, its structural design has obvious shortcomings: it requires rotating two tension screws to press the two pressing plates against the sheet. This structure is not only inconvenient to operate, but also increases the number of steps, seriously affecting the process of reinforcement and clamping, and reducing the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement clamping device for thin aluminum parts of a speaker, so as to solve the problem that the existing technology requires rotating two tension screws to press the two pressing plates against the thin part. This structure is not only inconvenient to operate, but also increases the operation steps, seriously affecting the reinforcement clamping process and reducing the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a speaker box aluminum sheet reinforcement clamping device, comprising a hollow base, with support frames on both sides of the top of the hollow base, an adjustment structure between the two support frames, a pressing platform on the top of the support frames, a reset structure between the pressing platform and the support frames, connecting blocks fixedly connected to the front and rear sides of the pressing platform, two threaded rods rotatably connected inside the hollow base, worm gears fixedly connected to the outer sides of the bottom ends of the two threaded rods, worm gears meshing with the outer sides of the two worm gears, mounting plates threadedly connected to the outer sides of the top ends of the two threaded rods, U-shaped pressure plates fixedly connected to the top of the two mounting plates, and the two U-shaped pressure plates passing through the top end of the hollow base and slidably connected to the hollow base.

[0007] Preferably, the adjustment structure includes an elongated frame disposed between two support frames. The elongated frame is fixedly connected to the top of the hollow base. A bidirectional screw is rotatably connected inside the elongated frame. A worm gear is fixedly connected to the outside of the bidirectional screw. A worm is meshed with the outside of the worm gear. Both ends of the worm pass through the inside of the elongated frame and are rotatably connected to the elongated frame. A throttle handle is installed at one end of the worm.

[0008] Preferably, the adjustment structure further includes two square blocks, four convex blocks, and four convex grooves. The two square blocks are threaded to the outside of a bidirectional screw. A U-shaped rod is fixedly connected to the outside of each of the two square blocks. One end of each U-shaped rod passes through the inside of a long frame and is slidably connected to the long frame. One end of each U-shaped rod is fixedly connected to two support frames. The four convex blocks are arranged in pairs, and the two pairs of convex blocks are fixedly connected to the bottom of the two support frames. The four convex grooves are all located at the top of the hollow base. The convex blocks are disposed inside the convex grooves and are slidably connected to the hollow base. The arrangement of the convex blocks and convex grooves improves the stability of the support frame movement.

[0009] Preferably, the two pressing platforms are respectively adapted to two support frames, and a rubber anti-slip pad is installed on one side of the bottom of each of the two pressing platforms. The rubber anti-slip pad can improve the stability of fixing the sheet.

[0010] Preferably, the reset structure further includes two T-shaped columns, both of which are disposed on the top of the pressing platform. The bottom ends of both T-shaped columns penetrate the pressing platform and are slidably connected to it. The bottom ends of both T-shaped columns are fixedly connected to the support frame. Springs are sleeved on the outer sides of both T-shaped columns. The two ends of the springs are fixedly connected to the T-shaped columns and the pressing platform, respectively. The springs serve to provide elastic tension and elastic reset.

[0011] Preferably, the two worm gears are fixedly connected, and one end of each worm gear passes through the inside of the hollow base and is rotatably connected to the hollow base. One end of one of the worm gears is equipped with a throttle handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The two pressing platforms of this application can clamp and reinforce thin aluminum sheets placed on two support frames. Since a rubber anti-slip pad is installed on one side of the bottom of the pressing platform, the rubber anti-slip pad can increase the friction between the thin aluminum sheet and the pad, thereby improving the stability of the fixation and preventing the thin aluminum sheet from sliding during processing. The process can be achieved by simply rotating the second handle to clamp and reinforce the thin aluminum sheet. The operation is simple and convenient, improving the efficiency of clamping and reinforcement. It solves the problem in the prior art that two tension screws need to be rotated to press the two pressing plates against the sheet, which is not convenient to operate, increases the operation steps, seriously affects the clamping and reinforcement process, and reduces the practicality of the device.

[0014] 2. This application utilizes the movement of two square blocks to drive two U-shaped rods to move in opposite directions, thereby pushing two support frames to move. During the movement of the support frames, the convex block slides inside the convex groove, playing a guiding and stabilizing role. Through the above operation, the position of the two support frames can be adjusted, allowing the device to accommodate and fix various sizes of thin aluminum sheets. This adjustment structure is simple and reliable, and can quickly adjust the distance between the support frames according to actual needs, expanding the applicability of the device and enabling it to meet the clamping requirements of thin aluminum sheets of different specifications, further improving the practicality and convenience of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution for a speaker box thin aluminum sheet reinforcement clamping device, including a hollow base 1, with support frames 2 on both sides of the top of the hollow base 1, an adjustment structure between the two support frames 2, a pressing platform 9 on the top of the support frame 2, and two pressing platforms 9 respectively adapted to the two support frames 2. Rubber anti-slip pads are installed on one side of the bottom of each of the two pressing platforms 9, and a reset structure is provided between the pressing platform 9 and the support frame 2. Connecting blocks 900 are fixedly connected to the front and rear sides of the pressing platform 9. Two threads are rotatably connected inside the hollow base 1. The rod 12 has two threaded rods 12 with worm gears 13 fixedly connected to the outer sides of their bottom ends. Worms 14 are meshed with the outer sides of the two worm gears 13. The two worms 14 are fixedly connected to each other. One end of each worm 14 passes through the inner side of the hollow base 1 and is rotatably connected to the hollow base 1. One end of one worm 14 is equipped with a throttle handle. Mounting plates 15 are threadedly connected to the outer sides of the top ends of the two threaded rods 12. U-shaped pressure plates 16 are fixedly connected to the top of the two mounting plates 15. The two U-shaped pressure plates 16 pass through the inner top end of the hollow base 1 and are slidably connected to the hollow base 1.

[0021] The reset structure also includes two T-shaped columns 10, both of which are located on the top of the pressing platform 9. The bottom ends of both T-shaped columns 10 penetrate the pressing platform 9 and are slidably connected to it. The bottom ends of both T-shaped columns 10 are fixedly connected to the support frame 2. Springs 11 are sleeved on the outside of both T-shaped columns 10, and the two ends of the springs 11 are fixedly connected to the T-shaped column 10 and the pressing platform 9, respectively.

[0022] Specifically, rotating the second throttle causes the two worm gears 14 to rotate inside the hollow base 1. Since the worm gears 14 are meshed with the worm wheel 13, the rotation of the worm gears 14 will drive the worm wheel 13 to rotate. The worm wheel 13 is fixedly connected to the outer side of the bottom end of the threaded rod 12. Therefore, the rotation of the worm wheel 13 will drive the threaded rod 12 to rotate inside the hollow base 1. The outer side of the top end of the threaded rod 12 is threadedly connected to the mounting plate 15. The rotation of the threaded rod 12 will cause the mounting plate 15 to move along the thread direction. The top of the mounting plate 15 is fixedly connected to the U-shaped pressure plate 16. The movement of the mounting plate 15 will cause the U-shaped pressure plate 16 to slide into the hollow base 1. The two U-shaped pressure plates 16 will press down on multiple connecting blocks 900. The connecting blocks 900 are fixedly connected to the front and rear sides of the pressing table 9. Therefore, the downward movement of the U-shaped pressure plates 16 will push the pressing table 9 towards the support. As the support frame 2 moves, the pressing platform 9 slides on the T-shaped column 10. During the movement of the pressing platform 9, the spring 11 will be elastically stretched. Through the above operation, the two pressing platforms 9 can clamp and reinforce the thin aluminum sheet placed on the two support frames 2. Since a rubber anti-slip pad is installed on one side of the bottom of the pressing platform 9, the rubber anti-slip pad can increase the friction between the pressing platform and the thin aluminum sheet, thereby improving the stability of the fixation and preventing the thin aluminum sheet from sliding during processing. This process can be achieved by simply rotating the second handle to clamp and reinforce the thin aluminum sheet. The operation is simple and convenient, which improves the efficiency of clamping and reinforcement. It solves the problem that in the prior art, two tension screws need to be rotated to press the two pressing plates against the thin sheet, which is not convenient to operate, increases the operation steps, seriously affects the clamping and reinforcement process, and reduces the practicality of the device.

[0023] Example: Figure 1 - Figure 4 As shown, the adjustment structure includes an elongated frame 3, which is positioned between two support frames 2. The elongated frame 3 is fixedly connected to the top of the hollow base 1. A bidirectional screw 4 is rotatably connected inside the elongated frame 3. A worm gear 5 is fixedly connected to the outside of the bidirectional screw 4. A worm 6 is meshed with the outside of the worm gear 5. Both ends of the worm 6 pass through the inside of the elongated frame 3 and are rotatably connected to it. A throttle handle is installed at one end of the worm 6. The adjustment structure also includes two square blocks 7, four convex blocks 200, and four convex grooves 100. Block 7 is threaded to the outside of the bidirectional screw 4. U-shaped rods 8 are fixedly connected to the outside of the two blocks 7. One end of each U-shaped rod 8 passes through the inside of the elongated frame 3 and is slidably connected to the elongated frame 3. One end of each U-shaped rod 8 is fixedly connected to the two support frames 2 respectively. The four convex blocks 200 are in pairs. The two sets of convex blocks 200 are fixedly connected to the bottom of the two support frames 2 respectively. The four convex grooves 100 are opened on the top of the hollow base 1. The convex blocks 200 are set inside the convex grooves 100 and are slidably connected to the hollow base 1.

[0024] Specifically, rotating the throttle causes the worm gear 6 to mesh with the worm wheel 5. The worm wheel 5 is fixedly connected to the outside of the double-acting screw 4. Therefore, the rotation of the worm gear 6 will drive the double-acting screw 4 to rotate inside the elongated frame 3. Two blocks 7 are threaded to the outside of the double-acting screw 4. The rotation of the double-acting screw 4 will cause the two blocks 7 to move in opposite directions. U-shaped rods 8 are fixedly connected to the outside of each block 7. One end of the U-shaped rod 8 passes through the inside of the elongated frame 3 and is slidably connected to the elongated frame 3. The other end is fixedly connected to two support frames 2 respectively. Therefore, the movement of the two blocks 7 will drive the two U-shaped rods 2 to rotate in opposite directions. The rod 8 moves in the opposite direction, thereby pushing the two support frames 2 to move. During the movement of the support frames 2, the convex block 200 slides inside the convex groove 100, playing a guiding and stabilizing role. Through the above operation, the position of the two support frames 2 can be adjusted, so that the device can be adapted to fix thin aluminum parts of various sizes. This adjustment structure is simple and reliable, and can quickly adjust the distance between the support frames 2 according to actual needs, expanding the applicability of the device and enabling it to meet the clamping requirements of thin aluminum parts of different specifications, further improving the practicality and convenience of the device.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
