Description

Technical Field

[0001] This utility model mainly relates to the technical field of automobile shock absorber tower processing, specifically an auxiliary positioning device for automobile shock absorber tower processing. Background Technology

[0002] In the automotive manufacturing industry, shock absorber towers are key components of the vehicle's suspension system, and their machining precision and quality directly affect the vehicle's driving stability and comfort. During the manufacturing process of shock absorber towers, precise positioning is required to ensure that each machining step is executed accurately, thereby guaranteeing that the dimensional and shape accuracy of the shock absorber tower meets design requirements.

[0003] One positioning method involves using a dedicated positioning device. This device uses components such as a base plate, support frame, slider, positioning pin, shims, and fastening nuts. By measuring the position of the positioning holes of the shock absorber tower and calculating the relative coordinates, the support frame is built to minimize the coordinate deviation of the positioning holes. The positioning holes are then installed on the corresponding positioning pins. After positioning is completed, testing and evaluation are performed. However, the support frame is used in large quantities and is quite cumbersome to use, which results in a significant amount of time required for each disassembly and assembly, thus affecting processing efficiency.

[0004] Therefore, this utility model provides a more direct and simple positioning method, reducing the time required for disassembly and assembly. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example

[0022] like Figures 1 to 3As shown, an auxiliary positioning device for processing automotive shock absorber towers includes a bearing base plate 10. A high-level support base 11 is provided at one end of the top of the bearing base plate 10. A central support platform 12 is provided on one side of the high-level support base 11 and at the top of the bearing base plate 10. A low-level support base 13 is provided on one side of the top of the bearing base plate 10. A set of symmetrically arranged inclined support bases 14 is provided at the other end of the top of the bearing base plate 10. At least one limiting strut 15 is embedded in the top of the central support platform 12. The top of the high-level support base 11, the low-level support base 13, and the inclined support base 14 are all provided with top pressure limiting struts 16.

[0023] The high-position support base 11, the low-position support base 13, and the inclined support base 14 are distributed on the sides of the central support platform 12. The high-position support base 11, the low-position support base 13, and the inclined support base 14 are all set according to the required positioning hole positions of the actual automotive shock absorber tower, such as... Figure 1 As shown, in this embodiment, an auxiliary positioning device with 7 positioning holes is provided, which includes 2 high-position support bases 11, 1 low-position support base 13, 2 inclined support bases 14, and 2 limiting struts 15.

[0024] It should be noted that in this embodiment, the automotive shock absorber tower is an irregularly shaped metal component. From an overall appearance perspective, automotive shock absorber towers typically have a relatively high vertical height and a relatively independent tower-like structure, resembling a small tower. This structural design allows it to provide sufficient strength and rigidity within a limited space to support the shock absorber and withstand various external forces. Simultaneously, the tower-like structure also facilitates the rational layout of surrounding components, optimizing the overall vehicle structure. Therefore, in various three-dimensional dimensions, some mounting holes are positioned higher, and some are positioned lower. Inevitably, some mounting holes or side sheet metal are angled. Based on this, high-position support bases 11, low-position support bases 13, and angled support bases 14 of different heights or angles are provided to accommodate mounting holes in different positions.

[0025] Based on the measured and selected mounting holes, namely the positioning holes of this auxiliary positioning device, the high-position support base 11, the low-position support base 13, and the inclined support base 14 are arranged.

[0026] The high-position support base 11, the low-position support base 13, and the inclined support base 14 are all provided with through holes 17 at their tops. The high-position support base 11, the low-position support base 13, and the inclined support base 14 are all provided with side holes 18 on one side. A support block 19 is provided on one side of the through hole 17. The side hole 18 is used to insert the limiting pin 181, and the support block 19 is used to support the positioning hole position of the automobile shock absorber tower.

[0027] A limiting pin 181 is embedded in the inner wall of the side hole 18, and a mating surface 182 is provided on one side of the limiting pin 181. The mating surface 182 serves two purposes: firstly, it restricts the insertion of the limiting pin 181 into the inner wall of the side hole 18 to a specific angle, effectively preventing the limiting pin 181 from rotating within the side hole 18; secondly, it engages with the mating groove 162 to limit the pressure limiting rod 16, preventing the pressure limiting rod 16 from moving during the processing.

[0028] The top of the side wall of the limiting support rod 15 is provided with a thread 151. A nut 152 is connected to the top of the limiting support rod 15 and the thread 151. A limiting ring 153 is provided on the side wall of the limiting support rod 15 at the bottom of the thread 151. The bottom of the limiting support rod 15 has the same structure as the bottom of the top pressure limiting rod 16, and also adopts the limiting method of limiting pin 181 and mating groove 162. The nut 152 is used to limit and fix the car shock absorber tower at the top of the limiting support rod 15, and the limiting ring 153 is used to support the positioning hole position of the car shock absorber tower.

[0029] The bottom of one end of the top pressure limiting rod 16 is provided with an insertion rod 161, and the side wall of the insertion rod 161 is provided with a mating groove 162. The bottom of the other end of the top pressure limiting rod 16 is provided with a mating rod 163.

[0030] The top of the side wall of the support block 19 is provided with a support plate 191, and the top of the support block 19 is provided with a mating hole 192. The mating rod 163 is provided correspondingly to the mating hole 192, and is used to embed the mating rod 163 into the mating hole 192 to prevent the movement of the top pressure limiting rod 16, effectively reducing the deviation of the Z axis during machining.

[0031] The working principle of this utility model is as follows:

[0032] In actual processing and use, the bearing base plate 10 is placed in the processing area. The top of the bearing base plate 10 has multiple mounting holes for fixing the high support base 11, the central support platform 12, the low support base 13, and the inclined support base 14. According to the position of the positioning holes measured by the automobile shock absorber tower, the above-mentioned components are installed. The setting height of the central support platform 12 is also related to the size of the automobile shock absorber tower. The central support platform 12 has a large contact area with the outer wall of the automobile shock absorber tower, which plays an important supporting role and effectively avoids the deformation and scrapping of the automobile shock absorber tower during processing due to the use of only multi-point limiting and fixing support.

[0033] Secondly, the limiting support rod 15 needs to be pre-installed in the hole at the top of the central support 12 and fixed by the limiting pin 181. Then the car shock absorber tower can be placed directly on the top of the device. Since the positioning hole is pre-measured, the operator does not need to measure it again. According to the operating standard, the car shock absorber tower can be placed at a specific angle. The operator does not need to undergo more professional training and can easily and accurately operate the car shock absorber tower for pre-processing installation and post-processing disassembly.

[0034] After the car shock absorber tower is installed, the top pressure limiting rod 16 is placed in the through hole 17 and fixed by limiting pin 181. The mating rod 163 is set to correspond with the mating hole 192 and the mating groove 162 is engaged to limit the top pressure limiting rod 16, so that the top pressure limiting rod 16 is limited and fixed. Finally, the nut 152 is screwed on the limiting support rod 15.

[0035] During disassembly, simply remove the nut 152 and the top pressure limit rod 16 in sequence to remove the car shock absorber tower. Other parts do not need to be disassembled before replacing the next car shock absorber tower.

[0036] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
