Description

Technical Field

[0001] This utility model belongs to the field of ceramsite processing technology, and specifically relates to a clamping device for assembling automotive parts. Background Technology

[0002] In modern transportation systems, automobiles are extremely common means of transportation. Their production involves many complex processes. Automobiles are composed of a large number of diverse automotive parts, each of which has a unique function and is a key element supporting the safe and stable operation of automobiles. In the automotive parts processing stage, precise and efficient fixing is crucial. However, many clamping devices on the market today have obvious shortcomings. On the one hand, most existing clamping devices are difficult to flexibly adapt to the clamping needs of cylindrical automotive parts of different sizes and lengths, which greatly limits their application in diverse production scenarios. On the other hand, these devices generally lack the function of driving the automotive parts to rotate.

[0003] For example, the existing technology, specifically the wear-resistant clamping device for machining automotive parts (authorized publication number CN216576805U), while achieving clamping of automotive parts of different sizes to some extent with the help of a worktable, support frame, automatic telescopic rod, and fixing block, cannot automatically rotate the parts during use. When different parts of the parts need to be processed, the operator has to manually adjust the position of the parts, which is not only cumbersome but also seriously affects processing efficiency. It is difficult to meet the growing demand for high-efficiency and high-precision production in the automotive manufacturing industry. It is evident that the existing technology has certain defects and shortcomings, and therefore, it needs to be improved and designed. Utility Model Content

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A clamping device for assembling automotive parts includes a frame, with support legs fixedly installed at the four corners of the top of the frame, a positioning platform fixedly installed on the top of the support legs, an adjustment mechanism fixedly installed in the middle of the positioning platform, and clamping mechanisms fixedly installed on both sides of the top of the adjustment mechanism.

[0007] The adjustment mechanism includes a rail frame, which is fixedly installed in the middle of the positioning platform. A first motor is fixedly installed on one side of the rail frame. The output end of the first motor is fixedly connected to a first lead screw through the rail frame. The first lead screw is rotatably connected to the inside of the rail frame. The two ends of the first lead screw have opposite thread directions. Both ends of the first lead screw are threadedly connected to movable blocks. The top of the movable blocks is connected to the bottom of the clamping mechanism.

[0008] As a preferred technical solution, the clamping mechanism includes a longitudinal adjustment group, which is fixedly installed on the top of the movable block. A rotating group is fixedly connected to the inner side of the longitudinal adjustment group, and a clamping group is fixedly installed on the inner side of the rotating group.

[0009] As a preferred technical solution, the longitudinal adjustment group includes a mounting frame, which is fixedly installed on the top of the movable block. An electric push rod is fixedly connected to the top of the mounting frame. The output end of the electric push rod passes through the mounting frame and is fixedly installed with a sliding block. The sliding block is slidably connected to the inner side of the mounting frame. The inner side of the mounting frame is connected to the rotation group.

[0010] As a preferred technical solution, the rotating assembly includes a connecting block, which is fixedly connected to the bottom of the sliding block. A concave seat is fixedly connected to the inner side of the connecting block, and an mounting plate is fixedly installed on the inner side of the concave seat. A rotating shaft is rotatably connected to the inner side of the mounting plate, and the inner side of the rotating shaft is connected to the clamping assembly. A second motor is fixedly connected to the inner side of one concave seat, and the output end of the second motor is connected to the rotating shaft.

[0011] As a preferred technical solution, the clamping assembly includes a guide rail, which is fixedly connected to the inner end of the rotating shaft. A third motor is fixedly connected to one end of the guide rail, and a second lead screw is fixedly connected to the output end of the third motor through the guide rail.

Displacement blocks are threaded to both ends of the second lead screw, and a clamping frame is fixedly installed on the inner side of the displacement blocks. The overall cross-sectional shape of the clamping frame is V-shaped.

[0012] As a preferred technical solution, a fixed plate is fixedly installed at the bottom of the guide rail on the side away from the second motor, and a load-bearing ball is fixedly connected to the bottom of the fixed plate.

[0013] As a preferred technical solution, the cross-sectional shape of the internal cavity of the rail frame and guide rail is set to a convex shape, and the overall shape of the movable block and displacement block is also set to a convex shape.

[0014] In summary, the present invention has the following main advantages:

[0015] First, by setting an adjustment mechanism, this device can effectively improve its adaptability to automotive parts of different sizes. When running, the first motor is started, which drives the first lead screw to rotate. Because the threads at both ends of the lead screw rotate in opposite directions, the movable block slides in the opposite direction, thereby causing the clamping mechanism to move. By precisely adjusting the distance between the two clamping mechanisms, the device can flexibly adapt to parts of different sizes, effectively improving its versatility and adaptability, and making the equipment easier to use.

[0016] Secondly, by setting up a rotating group and a clamping group to work together, this device can effectively improve the convenience and stability of clamping and processing automotive parts. During the part clamping stage, the part is placed inside the V-shaped clamping frame, the third motor is started, and the second lead screw drives the displacement block to slide on the guide rail, thereby driving the clamping frame to achieve stable positioning. After positioning, the second motor is started to drive the clamping group to rotate, so that the part can be flexibly flipped. The fixed plate at the bottom of the guide rail and the load ball increase gravity to maintain balance and enhance overall stability. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 5This embodiment of a clamping device for assembling automotive parts includes a frame 1, with support legs 2 fixedly installed at the four corners of the top of the frame 1, a positioning platform 4 fixedly installed on the top of the support legs 2, an adjustment mechanism 3 fixedly installed in the middle of the positioning platform 4, and clamping mechanisms 5 fixedly installed on both sides of the top of the adjustment mechanism 3.

[0025] The adjustment mechanism 3 includes a rail frame 31, which is fixedly installed in the middle of the positioning platform 4. A first motor 32 is fixedly installed on one side of the rail frame 31. The output end of the first motor 32 passes through the rail frame 31 and is fixedly connected to a first lead screw 33. The first lead screw 33 is rotatably connected to the inside of the rail frame 31. The two ends of the first lead screw 33 have opposite threads. Both ends of the first lead screw 33 are threadedly connected to movable blocks 34. The top of the movable blocks 34 is connected to the bottom of the clamping mechanism 5. When the adjustment mechanism 3 of this automotive parts assembly clamping device is working, the first motor on one side of the rail frame 31 is activated. 32. The output end of the first motor 32 rotates, driving the first lead screw 33 that passes through the rail frame 31 to rotate inside it. Since the threads at both ends of the first lead screw 33 rotate in opposite directions, the movable blocks 34 threaded to both ends of the lead screw will move in opposite directions due to the rotation of the lead screw. The top of the movable block 34 is connected to the bottom of the clamping mechanism 5, and its movement drives the clamping mechanism 5 to move synchronously. In this way, by rotating the first motor 32 forward and reverse, the distance between the two clamping mechanisms 5 can be precisely controlled, thereby adapting to different sizes of automotive parts and meeting the diverse clamping needs in the assembly process of automotive parts.

[0026] refer to Figures 1-5 The clamping mechanism 5 includes a longitudinal adjustment group 51, which is fixedly installed on the top of the movable block 34. A rotating group 52 is fixedly connected to the inner side of the longitudinal adjustment group 51, and a clamping group 53 is fixedly installed on the inner side of the rotating group 52. When the clamping mechanism 5 is working, when the adjustment mechanism 3 drives the movable block 34 to move, the longitudinal adjustment group 51 moves horizontally. After the longitudinal adjustment group 51 is started, it can adjust its height according to actual needs, thereby changing the position of the clamping mechanism 5 in the vertical direction to adapt to car parts of different heights. After the longitudinal position adjustment is completed, the rotating group 52 starts to work. It is driven by an internal power device to drive the clamping group 53 to rotate around a specific axis, which can adjust the car parts placed on the clamping group 53 to the required angle for subsequent assembly operations. Finally, the clamping group 53 is started. Through its own mechanical structure, such as the closing or opening of the grippers, it stably clamps the car parts. All parts work together in the whole process to achieve precise and flexible clamping and positioning of the car parts.

[0027] refer to Figures 4-5The longitudinal adjustment assembly 51 includes a mounting frame 511, which is fixedly mounted on the top of the movable block 34. An electric push rod 512 is fixedly connected to the top of the mounting frame 511. A sliding block 513 is fixedly mounted through the mounting frame 511 at its output end. The sliding block 513 is slidably connected to the inner side of the mounting frame 511. The inner side of the mounting frame 511 is connected to a rotating assembly 52. ​​The rotating assembly 52 includes a connecting block 521, which is fixedly connected to the bottom of the sliding block 513. A concave seat 522 is fixedly connected to the inner side of the connecting block 521. A mounting plate 523 is fixedly mounted on the inner side of the concave seat 522. A rotating shaft 524 is rotatably connected to the inner side of the mounting plate 523. The inner side of the rotating shaft 524 is connected to a clamping assembly 53. A second motor 525 is fixedly connected to the inner side of one of the concave seats 522. The output end of the second motor 525 is connected to the rotating assembly 523. The shaft 524 is connected to the clamping assembly 53, which includes a guide rail 531. The guide rail 531 is fixedly connected to the inner end of the rotating shaft 524. A third motor 532 is fixedly connected to one end of the guide rail 531. The output end of the third motor 532 passes through the guide rail 531 and is fixedly connected to a second lead screw 533. The second lead screw 533 is rotatably connected to the inside of the guide rail 531. The two ends of the second lead screw 533 have opposite threads. Both ends of the second lead screw 533 are threadedly connected to displacement blocks 534. A clamping frame 535 is fixedly installed on the inner side of the displacement block 534. The overall cross-sectional shape of the clamping frame 535 is V-shaped. During the use of this device, the mounting frame 511 can be moved horizontally by moving the movable block 34. The electric push rod 512 is activated, and its output end pushes the sliding block 513 to slide vertically inside the mounting frame 511, thereby realizing the height adjustment of the rotating assembly 52 and the clamping assembly 53. When the part angle needs to be adjusted, the second motor 525 is turned on, and its output end drives the rotating shaft 524 to rotate within the mounting plate 523, which in turn drives the guide rail 531 connected to the inner end of the rotating shaft 524 to rotate, thus rotating the part. When clamping the part, the third motor 532 operates, driving the second lead screw 533 to rotate within the guide rail 531. Because the threads at both ends of the lead screw rotate in opposite directions, the displacement blocks 534 at both ends slide towards or away from each other. The V-shaped clamping frame 535 on the inner side of the displacement block 534 moves closer or further away accordingly, achieving stable clamping of parts of different sizes. All parts work together to complete the precise clamping and flexible adjustment of automotive parts.

[0028] refer to Figure 5A fixed plate 536 is fixedly installed at the bottom of the guide rail 531 on the side away from the second motor 525. A load-bearing ball 537 is fixedly connected to the bottom of the fixed plate 536. The cross-sectional shape of the internal cavity of the rail frame 31 and the guide rail 531 is set as a convex shape. The overall shape of the movable block 34 and the displacement block 534 is also set as a convex shape. When this device is working, the convex design of the internal cavity of the rail frame 31 and the guide rail 531, as well as the movable block 34 and the displacement block 534, plays a key role. The convex structure restricts the movement direction of the movable block 34 in the rail frame 31 and the displacement block 534 in the guide rail 531. To prevent deviation or disengagement when moving horizontally or along the guide rail 531, ensuring the stability and precision of the movement, the fixed plate 536 and the load ball 537 installed at the bottom of the guide rail 531 on the side away from the second motor 525 increase the gravity at the bottom of the guide rail 531 on that side, effectively balancing the eccentric torque generated by the placement of parts and the action of the clamping mechanism 5, so that the guide rail 531 remains stable during operation, avoiding tilting or shaking, providing a stable foundation for the precise clamping and processing of automotive parts, and ensuring the smoothness and reliability of the entire device operation.

[0029] Operating principle and advantages: This device, by setting the adjustment mechanism 3, can effectively improve its adaptability to parts of different sizes during the processing of automotive parts. When the device is running, the first motor 32 is started. The power generated by the first motor 32 drives the first lead screw 33 to rotate. Since the threads at both ends of the first lead screw 33 rotate in opposite directions, when the first lead screw 33 rotates under the drive of the first motor 32, the movable block 34 connected to it will slide in the opposite direction on the lead screw. The sliding of the movable block 34 will then drive the clamping mechanism 5 connected to it to move back and forth. By precisely controlling the distance between the two clamping mechanisms 5, this device can flexibly adapt to automotive parts of different sizes, which can effectively improve the versatility and adaptability of the device in actual use and facilitate the use of this equipment.

[0030] This device, by combining a rotating assembly 52 with a clamping assembly 53, significantly improves the convenience and stability of clamping and processing automotive parts. During the part clamping stage, the automotive part to be processed is placed inside the clamping frame 535. Then, the third motor 532 is activated, driving the second lead screw 533 to rotate. The rotation of the second lead screw 533 synchronously drives two displacement blocks 534 to slide in opposite directions within the guide rail 531. The sliding of the displacement blocks 534 moves the clamping frame 535. By precisely adjusting the positions of the two clamping frames 535, stable clamping and positioning of the automotive part is achieved. The clamping frame 535 adopts a V-shaped cross-section design, which can closely fit automotive parts of different sizes, ensuring secure clamping. To ensure stability and reliability, after the part is clamped and positioned, the second motor 525 inside the concave seat 522 is activated. The second motor 525 drives the entire clamping assembly 53 to rotate around a specific axis, thereby enabling flexible flipping and angle adjustment of the clamped part. This design allows operators to easily process various parts of the part, greatly improving the ease of use and adaptability of the device. In addition, the fixed plate 536 and the load ball 537 set at the bottom of the guide rail 531 effectively maintain the balance of the guide rail 531 during the clamping and adjustment process by increasing the gravity at the middle position of the bottom of the guide rail 531, further enhancing the overall stability of the device and providing a solid guarantee for the rapid and accurate clamping and positioning of automotive parts.
