Description

Technical Field

[0001] This utility model relates to the field of automotive parts clamping technology, specifically a multi-station clamping fixture for automotive chassis parts. Background Technology

[0002] As the core load-bearing and power transmission hub of a vehicle, the chassis is not only the basic carrier supporting the body and integrating the engine and various functional components, but also one of the three core assemblies of a car. The control arm, as a key force-transmitting component of the chassis suspension system, has its machining accuracy directly related to the motion coordination of the suspension system and the overall vehicle driving stability. In precision machining processes such as drilling and milling of the control arm, reliable positioning and fixation are achieved through specialized clamping fixtures to ensure dimensional accuracy and consistency. Therefore, the performance of the clamping fixtures is crucial to the machining quality and efficiency of the control arm.

[0003] In the prior art, such as the Chinese utility model patent with authorization announcement number CN222587840U, a clamping fixture for a car triangular swing arm is disclosed. The fixture includes a clamping platform, a control component, a moving column, and a clamping cover. The control component is fixedly installed on the lower end face of the clamping platform, and its output end is connected to the moving column to drive the moving column to move. The clamping cover is installed on the upper end of the moving column. A sliding groove is provided on the clamping platform, and the clamping cover moves through the sliding groove and abuts against the car triangular swing arm. The control component drives the moving column and the clamping cover to work together to achieve the clamping and fixing of the triangular swing arm.

[0004] However, the existing tooling only has single-station clamping capability, and can only position and fix one swing arm component in each processing cycle, which is difficult to adapt to the batch processing needs of the large-scale production scenario of automotive parts. At the same time, the structural design of the tooling is specifically designed for triangular swing arms, and its adaptability is limited. However, there are various types of swing arms in the automotive chassis system (such as straight arms, trapezoidal arms, U-shaped arms, etc.), and the structural differences between different types of swing arms are obvious, which makes the tooling incompatible with the clamping and positioning of different types of swing arms, and its applicability is limited. In order to address the above problems, we provide a multi-station clamping tooling for automotive chassis components. Utility Model Content

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.

[0026] Please see Figure 1 In this embodiment of the utility model, a multi-station clamping fixture for automotive chassis parts includes a base plate 1. The base plate 1 has strip-shaped holes 11 near its four sides. An mounting plate 3 is provided on the top of the base plate 1. Fixing rods 20 are fixedly connected to the base plate 1 at the four corners of the mounting plate 3.

[0027] Please see Figure 5 The mounting plate 3 has several mounting openings 10, each of which is detachably connected to a contouring seat for placing a car swing arm. The contouring seat includes a contouring carrier plate 8, which has a contouring groove 16 for placing the car swing arm. A chip discharge port 17 penetrating the contouring carrier plate 8 is provided within the contouring groove 16. The edge of the contouring carrier plate 8 is provided with a fixing component for fixing to the mounting plate 3. The contouring groove 16 on the contouring carrier plate 8 is mainly used for placing and positioning the car swing arm. The shape of the contouring groove 16... The shape precisely matches the outer surface contour of the swing arm to be processed, enabling the car swing arm to be stably placed in the contour groove 16. At the same time, the contour constraint of the contour groove 16 achieves positioning, effectively ensuring the positional accuracy of the car swing arm each time it is placed, providing a stable reference for subsequent drilling, milling and other processing procedures. In addition, the chip discharge port 17 synchronously set on the contour carrier plate 8 can directly discharge the chips generated during drilling, milling and other processing that fall to the bottom of the contour carrier plate 8, avoiding chip accumulation that affects the positioning accuracy of the swing arm or scratches the surface of the parts.

[0028] Please see Figure 5 The fixing component includes a fixing edge 15. Both sides of the contouring carrier plate 8 are fixedly connected to the fixing edge 15. Both sides of the fixing edge 15 are provided with through holes 18. The mounting plate 3 is provided with second threaded holes 19 on both sides of the mounting opening 10, which are matched with the positions of the through holes 18. Fastening screws 6 are inserted into the through holes 18 and are threadedly connected to the second threaded holes 19. The contouring carrier plate 8 is fixed to the mounting plate 3 by fastening screws 6, which can be easily disassembled. This allows the contouring carrier plate 8 with the corresponding shape contouring groove 16 to be replaced according to the type of swing arm being processed, greatly improving its applicability.

[0029] Please see Figures 1-3Support rods 7 are provided on both sides above the mounting port 10. Sliding rods 4 are fixedly connected to both ends of the support rods 7. The sliding rods 4 are slidably connected to the mounting plate 3. A push plate 9 is fixedly connected between the lower ends of the four sliding rods 4. A lifting assembly for pushing the push plate 9 up and down is provided on the base plate 1. The lifting assembly includes cylinders 21. The cylinders 21 are respectively located on the base plate 1 below the push plate 9. The cylinders 21 are fixedly connected to the base plate 1. The output end of the cylinders 21 is fixedly connected to the push plate 9. The cylinders 21 can drive the push plate 9 to move up and down during operation. The movement of the push plate 9 can drive the sliding rods 4 to move up and down accordingly, thereby driving the clamping assembly to move accordingly, so as to realize the clamping or releasing action.

[0030] Please see Figure 3 and Figure 4 The support rod 7 is equipped with a clamping assembly for clamping the car swing arm. The clamping assembly includes a clamping rod 5, and both ends of the clamping rod 5 are fixedly connected to sliding sleeves 12. The sliding sleeves 12 are slidably connected to the support rod 7. The upper end of each sliding sleeve 12 is provided with a first threaded hole, and a locking screw 14 for locking the position of the clamping rod 5 is threaded into the first threaded hole. The lower end face of each clamping rod 5 is affixed with a rubber strip 13. The clamping rod 5 can press against the car swing arm when clamping it, thereby fixing the car swing arm. At the same time, the position of the clamping rod 5 can be adjusted so that it can be adjusted to a suitable pressing position according to the type of car swing arm to fix the swing arm. When adjusting, first loosen the locking screw 14, then slide the clamping rod 5 to adjust, and after adjustment, tighten the locking screw 14 to lock the position of the sliding sleeve 12.

[0031] Please see Figure 1 and Figure 2 Each of the mounting plates 3 is fixedly connected to a slag discharge hopper 2 at the lower end of the mounting port 10. The slag discharge hoppers 2 are distributed on both sides of the mounting plate 3, and the outlets of the slag discharge hoppers 2 on both sides face opposite directions. The slag discharge hoppers 2 can guide the falling debris and discharge it in a designated direction.

[0032] Please see Figures 1-6The working principle of this utility model is as follows: When in use, the car swing arm to be processed is placed into the contour groove 16 on the contour plate 8. Then, the cylinder 21 can drive the push plate 9 to move up and down. The movement of the push plate 9 can drive the sliding rod 4 to move up and down accordingly, which in turn can drive the clamping rod 5 to move down to clamp the swing arm, so as to facilitate the subsequent processing of the swing arm. At the same time, the chip discharge port 17 is provided to discharge the chips that fall to the bottom during drilling, milling and other processing. Meanwhile, the contour plate 8 is fixed to the mounting plate 3 with fastening screws 6, which can be easily disassembled. When in use, the contour plate 8 with the corresponding shape of the contour groove 16 can be replaced according to the type of swing arm being processed. At the same time, with the adjustable clamping components, the fixing requirements of different types of car swing arms can be met, which greatly improves the applicability of the tooling.
