Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a rigid support fixture assembly for automobile front suspension springs. Background Technology

[0002] The front suspension spring is an important elastic component in the automotive suspension system, playing a crucial role in the vehicle's comfort and handling performance. It ensures that the vehicle maintains a stable body height whether fully loaded or unloaded, guaranteeing driving safety and vehicle passability. During vehicle turning, braking, and other operations, the spring prevents the body from excessively tilting or pitching, keeping the vehicle in a good posture and improving handling stability.

[0003] To inspect the dimensional accuracy, geometric tolerances, and assembly compatibility of rigid support components in the front suspension spring structure of automobiles before they leave the factory, a dedicated rigid support fixture assembly for automotive front suspension springs is required. Existing equipment can inspect the corresponding front suspension springs on the production line, but during inspection, screws and nuts are needed to fix the front suspension springs and their associated structures to the inspection table. After inspection, the nuts are manually turned to disassemble them, which is a cumbersome process that reduces practicality and inspection efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rigid support fixture assembly for automotive front suspension springs, aiming to improve the existing rigid support fixture assembly for automotive front suspension springs, which requires manual twisting of nuts to disassemble after inspection, a cumbersome process that reduces practicality and inspection efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rigid support fixture assembly for a front suspension spring of an automobile, comprising a base, a support column fixedly connected to the top rear side of the base, multiple guide rails fixedly connected to the front side of the support column, guide blocks slidably connected to the inner walls of the guide rails, and pins slidably connected to the inner walls of the guide blocks, a positioning seat fixedly connected to the top front side of the base, multiple positioning holes being provided on the top of the positioning seat, and a positioning block fixedly connected to the middle of the front side of the support column.

[0006] As a further description of the above technical solution:

[0007] Positioning feet are fixedly connected to the four corners at the bottom of the base.

[0008] As a further description of the above technical solution:

[0009] Screws are threaded at the four corners of the top of the base.

[0010] As a further description of the above technical solution:

[0011] An indicator is fixedly connected to the top of the base near the edge.

[0012] As a further description of the above technical solution:

[0013] A front suspension spring is slidably connected to the inner wall of the positioning hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the front suspension spring to be tested is initially positioned axially by placing it vertically in the positioning hole at the top of the positioning seat. Then, the top of the front suspension spring is positioned by a pin. The positioning block, as an auxiliary positioning structure, contacts the side wall of the spring to prevent radial displacement during the testing process. Finally, the positioning seat, together with the positioning hole, can position the bottom of the object to be tested, which speeds up the work efficiency and expands the scope of application.

[0022] 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.

[0023] Please see the appendix Figure 2- Appendix Figure 4 An embodiment of this utility model provides a rigid support fixture assembly for a front suspension spring of an automobile, including a base 1, a support column 2 fixedly connected to the top rear side of the base 1, a plurality of guide rails 6 fixedly connected to the front side of the support column 2, a guide block 3 slidably connected to the inner wall of the guide rail 6, a pin 4 slidably connected to the inner wall of the guide block 3, a positioning seat 5 fixedly connected to the top front side of the base 1, a plurality of positioning holes 8 opened on the top of the positioning seat 5, a positioning block 12 fixedly connected to the middle of the front side of the support column 2, and a front suspension spring 7 slidably connected to the inner wall of the positioning hole 8.

[0024] Specifically, the base 1 serves as the main load-bearing body of the entire inspection fixture, ensuring the stability of the overall structure during the inspection process. The support column 2 is used to support and install the remaining structures. The guide rail 6 guides the sliding direction of the guide block 3, preventing it from deviating from the predetermined movement trajectory. The positioning seat 5, in conjunction with the positioning hole 8, can position the bottom of the object to be inspected.

[0025] Please see the appendix Figure 1 - Appendix Figure 3 Positioning feet 10 are fixedly connected to the four corners at the bottom of the base 1;

[0026] Specifically, the positioning feet 10 can prevent the bottom of the base 1 from contacting the ground, thus preventing wear on the bottom of the base 1 caused by shaking during the testing process.

[0027] Please see the appendix Figure 1 - Appendix Figure 3 Screws 9 are threadedly connected to the four corners of the top of the base 1;

[0028] Specifically, screw 9 can position base 1 for installation.

[0029] Please see the appendix Figure 1 - Appendix Figure 3 An indicator 11 is fixedly connected to the top of the base 1 near the edge;

[0030] Specifically, indicator table 11 is used to indicate the values ​​after the structure is tested.

[0031] Working principle: During testing, the front suspension spring 7 to be tested is placed vertically in the positioning hole 8 at the top of the positioning seat 5 to achieve initial axial positioning of the spring. Through the sliding connection between the guide rail 6 on the front side of the support column 2 and the guide block 3, the support position of the guide block 3 can be adjusted laterally. The pin 4 can position the top of the front suspension spring 7. The positioning block 12, as an auxiliary positioning structure, contacts the side wall of the front suspension spring 7 to prevent radial displacement during the testing process. During testing, the deformation of the spring under compression is monitored in real time by the indicator 11 at the top edge of the base 1. The rigidity test can be completed by comparing with the standard parameters. The positioning seat 5, together with the positioning hole 8, can position the bottom position of the object to be tested.

[0032] 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.
