Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to a rotary clamping fixture for automotive parts. Background Technology

[0002] With the rapid development of the automotive industry, the requirements for precision and efficiency in the production and assembly of automotive parts are increasing. On the automotive parts production line, the clamping of parts is a key process that directly affects the machining accuracy, assembly quality and production efficiency of the parts.

[0003] A search revealed Chinese Patent Publication No. CN220427517U, which discloses a rotary clamping fixture for automotive parts. This fixture includes a base plate with clamping mechanisms at both ends of its top. One clamping mechanism has a concentric rotation mechanism on one side, and a reciprocating adjustment mechanism is also provided on the top of the base plate. This rotary clamping fixture for automotive parts allows for the rapid clamping of both ends of the automotive parts during machining. After clamping, the parts are positioned in a horizontal and concentric state, ensuring perpendicularity to the machining tool. Before clamping, the reciprocating adjustment mechanism controls the movement of the moving plate to match the length of the automotive parts, accommodating clamping operations of different sizes. After clamping, machining operations are performed. When a change in machining angle is needed after machining, the concentric rotation mechanism is used to rotate and control the machining angle adjustment to other machining positions, thereby improving machining efficiency and quality.

[0004] The aforementioned technologies, while achieving the rapid clamping of both ends of automotive parts during machining using a clamping mechanism and ensuring their horizontal concentricity and perpendicularity to the machining tool, suffer from several drawbacks. While the clamping mechanism can effectively center the outer wall of the automotive part, the small contact point between the clamping rods and the outer wall may affect the clamping effect. Furthermore, the direct contact between the clamping rods and the outer wall lacks protection, and the high compressive force could damage the automotive part. Therefore, a rotary clamping fixture for automotive parts is proposed to address these issues. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a rotary clamping fixture for automotive parts, which aims to improve the problems in the prior art where "the small contact point between the clamping rod and the outer wall of the automotive part may lead to unstable clamping effect, and the direct contact with the automotive part lacks sufficient protection, which may cause damage to the automotive part, especially under large compressive force".

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a rotary clamping fixture for automotive parts, including a base 1 for stable support of the device components. Two sets of slide tables 2 are slidably connected to the inner wall of the top of the base 1, respectively positioned on both sides of a bidirectional threaded rod 3. The bidirectional threaded rod 3 is rotatably connected to the inner wall of the top of the base 1, driving the two sets of slide tables 2 to move in opposite directions via the threads, thereby adjusting the size of the automotive parts to be clamped as needed, thus improving the applicability and flexibility of the device. The inner wall of the bottom of the slide table 2 is threaded to the outer wall of the bidirectional threaded rod 3. A reduction motor 4 is located on the left side of the slide table 2 for driving... The moving gear 6 rotates slowly in one direction, thereby driving the limiting ring 51 to rotate, thus adjusting the angle of the clamped automotive parts. The angle adjustment is more precise and controllable. The outer wall of the slide table 2 is provided with a clamping assembly, which includes the limiting ring 51. The outer inner wall of the limiting ring 51 is rotatably connected to the inner wall of the slide table 2 and can rotate around the central axis of the slide table 2, thereby realizing the angle adjustment of the clamped automotive parts. At the same time, the interior is hollow to allow gas to flow. The left outer wall of the limiting ring 51 is fixedly connected with teeth 53, which mesh with the gear 6, so that the reduction motor 4 can drive the limiting ring 51 to rotate.

[0034] Reference Figure 2 - Figure 4A mounting tube 54 is fixedly connected to the rear side of the slide table 2 for connecting an air pump. Gas is filled into the mounting tube 54. The mounting tube 54 surrounds the inner wall of the slide table 2 and communicates with the moving rod 71. A sleeve 55 is fixedly connected to the inner side of the limiting ring 51. A slide cylinder 56 is piston-connected to the inner wall of the sleeve 55, allowing the slide cylinder 56 to move within the sleeve 55. A sliding rod 57 is piston-connected to the inner wall of the slide cylinder 56. The gas thrust drives the sliding rod 57 to slide against the inner wall of the slide cylinder 56, simultaneously pushing the extrusion pad 59 against the outer wall of the automotive part. A connecting block 58 is rotatably connected to the front end of the sliding rod 57. This rotatable connection gives the extrusion pad 59 a certain degree of steering ability when in contact with the automotive part, thereby improving the adhesion between the extrusion pad 59 and the outer wall of the automotive part, and thus improving the device's performance against automotive parts. To ensure the stability of component clamping, a compression pad 59 is fixedly connected to the front end of the connecting block 58. The compression pad 59 is made of rubber, which increases the friction between the compression pad and the automotive parts, improving the stability of clamping and reducing wear or damage to the automotive parts during clamping. Rubber also has good deformation capacity, which means that the compression pad 59 can deform to a certain extent according to the shape of the automotive parts, thereby better adapting to different clamping requirements. This not only improves the flexibility of clamping but also makes the clamping process more stable and reliable. The rear side of the slide rod 57 is elastically connected to the limiting ring 51 through a tension spring 52. When the mounting tube 54 is not inflated, the elastic force of the tension spring 52 drives the slide rod 57 to return to its original position, thereby driving the slide cylinder 56 to return to its original position and releasing the limitation on the automotive parts.

[0035] Reference Figure 4 - Figure 6A gear 6 is fixedly connected to the right side of the output shaft of the geared motor 4. The rotation of the output shaft of the geared motor 4 drives the gear 6 to rotate. The outer side of the gear 6 meshes with the outer wall of the tooth 53. The meshing of the gear 6 with the tooth 53 drives the limit ring 51 to rotate. A sliding groove 8 is provided through the outer side of the limit ring 51. The rotation of the limit ring 51 causes the inner wall of the sliding groove 8 to press against the outer side of the connecting plate 73, while simultaneously connecting the hollow area inside the limit ring 51. A connecting assembly is provided on the inner walls of both sides of the slide table 2. The connecting assembly includes a moving rod 71. The piston on the outer right side of the moving rod 71 is connected to the inner wall of the slide table 2. The air pressure on the inner wall of the slide table 2 compresses the moving rod 71, causing it to slide out of the inner wall of the slide table 2. When the moving rod 71 slides into the inner wall of the slide table 2, it blocks the connecting groove 72, thereby preventing air pressure leakage. The connecting groove 72 is provided on the inner right side of the moving rod 71 for... The hollow areas inside the connecting slide 2, the sliding groove 8, and the limiting ring 51 allow air pressure to enter the hollow area inside the limiting ring 51, thereby driving multiple sets of sliding cylinders 56 and sliding rods 57 to move and clamp and limit the automotive parts. The left side of the moving rod 71 is hinged to a connecting plate 73. Through the squeezing of the inner wall of the sliding groove 8, the moving rod 71 is driven to slide into the inner wall of the slide 2, thereby preventing gas leakage when the limiting ring 51 rotates. The lower end of the connecting plate 73 is slidably connected to the inner wall of the slide 2. Multiple sets of moving rods 71, connecting grooves 72, and connecting plates 73 are arranged in a circumferential array on both sides of the inner wall of the slide 2. Through multiple sets, the limiting ring 51 can respond quickly to the corresponding moving rod 71 whenever air pressure needs to be replenished at any position when it rotates. The inner wall of the limiting ring 51 slides on the outside of the connecting plate 73.

[0036] Working principle: In use, the car parts are first placed between multiple sets of compression pads 59. Then, gas is introduced into the slide table 2 through the mounting pipe 54. The gas moves the moving rod 71 to the outside of the slide table 2, pops out through the sliding groove 8 on the limiting ring 51, and sends the gas into the inner wall of the limiting ring 51 through the connecting groove 72 on the moving rod 71. The gas then enters the slide cylinder 56 and the slide rod 57, causing the piston of the slide cylinder 56 to slide on the inner wall of the sleeve 55 and the piston of the slide rod 57 to slide on the inner wall of the slide cylinder 56. This causes the compression pads 59 to contact and compress the car parts, thereby limiting the car parts. When the compression pads 59 compress the car parts, the connecting block 58 rotates on the slide rod 57, allowing the compression pads 59 to fit tightly against the outer wall of the car parts, improving the stability of the clamped car parts. At the same time, it can adapt to car parts of different shapes and specifications, thereby improving the applicability of the device.

[0037] When the angle of the automotive parts needs to be adjusted, the reduction motor 4 is started, which drives the output shaft of the reduction motor 4 to rotate slowly. At the same time, the gear 6 rotates. When the gear 6 rotates, it meshes with the teeth 53, which drives the limit ring 51 to rotate. This causes the clamped automotive parts to adjust their angle. While the limit ring 51 rotates, it squeezes the connecting plate 73 through the slide groove 8, causing the connecting plate 73 to squeeze the moving rod 71 into the inner wall of the slide table 2. This causes the connecting groove 72 to contact the inner wall of the slide table 2, thereby blocking the connecting groove 72 and preventing gas leakage. While the limit ring 51 rotates, it also drives the slide groove 8 to rotate. The slide groove 8 provides space for the movement of the moving rod 71, thereby filling the inner wall of the limit ring 51 with gas to facilitate stable clamping of the automotive parts.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
