Description

Technical Field

[0001] This utility model relates to the field of vibration damper testing technology, and in particular to a rapid testing device for welding points based on the positioning of vibration damper lifting lugs. Background Technology

[0002] In the fields of automobile manufacturing and machinery processing, shock absorber hangers are key components connecting the vehicle body and the shock absorber, and their welding quality directly affects the safety and stability of the entire vehicle. Due to the thermal deformation characteristics of welded parts and the dimensional fluctuations of raw material parts, the dimensions of various parts of the welded shock absorber will vary, requiring the use of testing equipment to complete this task.

[0003] In existing technologies, vibration dampers typically require fixation during inspection. However, due to the varying shapes of vibration dampers, the positioning of the lifting lugs cannot be modified, leading to inaccurate inspections. Therefore, we propose a rapid welding point inspection device based on the positioning of the vibration damper lifting lugs to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, when testing a shock absorber, it is usually necessary to fix it. However, due to the different shapes of shock absorbers, the positioning of the shock absorber lugs cannot be changed, resulting in inaccurate testing. Therefore, this invention proposes a rapid testing device for welding points based on the positioning of the shock absorber lugs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid welding point detection device based on vibration damper lug positioning includes a detection table and a vibration damper body. The outer wall of the vibration damper body is connected to a connector, a valve shell inclinedly disposed on the vibration damper body, and a lug fixed to a first end of the vibration damper body. The device also includes:

[0007] The clamping mechanism includes a positioning seat fixed on the first end of the carrier, a slider symmetrically sliding on the positioning seat, and fixing blocks respectively fixed on the top of the two positioning seats and in contact with each other. The carrier is equipped with a first support above the positioning seat corresponding to the slider, a return spring fixed on the first support and between the slider, and a disc fixed on the side of the slider.

[0008] The testing mechanism includes a testing seat mounted on the edge of the vehicle, a multi-directional testing frame fixed on the testing seat, and testing pins for testing the connector and the valve body.

[0009] Furthermore, the two disks are fitted with liftable wedge blocks and a first clamp for driving the wedge blocks to lift.

[0010] Furthermore, the carrier is equipped with a second support near the positioning seat for the wedge block to slide on.

[0011] Furthermore, the carrier is equipped with a third support for the first clamp to drive the wedge block to move.

[0012] Furthermore, the carrier is equipped with a go / no-go gauge for detecting the height of the valve body.

[0013] Furthermore, a support is mounted on the vehicle, and the shock absorber body is located on the support.

[0014] Furthermore, the carrier is equipped with a fixed base near the support and a second clamping clamp disposed on the fixed base.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. This solution utilizes the cooperation between the lifting lugs and the fixing blocks, as well as the linkage of components such as the slider and wedge blocks, to achieve multi-directional stable fixation of the shock absorber body, ensuring that the shock absorber body will not shift during subsequent operation or testing, thus providing a stable foundation for accurate testing and related operations.

[0017] 2. In this solution, staff members use a handheld go / no-go gauge to check the height of the valve body. This method is very simple and convenient to operate, requiring no complicated equipment or cumbersome procedures. Staff can quickly check on-site and obtain relevant data on the valve body height in a timely manner. Attached Figure Description

[0024] 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.

[0025] Reference Figures 1-3 A rapid welding point detection device based on the positioning of a vibration damper lifting lug includes a detection table and a vibration damper body 101. A connector 102, a valve shell inclinedly disposed on the vibration damper body 101, and a lifting lug 103 fixed to the first end of the vibration damper body 101 are connected to the outer wall of the vibration damper body 101. The device is characterized by further comprising:

[0026] The clamping mechanism includes a positioning seat 2 fixed to the first end of the carrier 1, a slider 201 symmetrically sliding on the positioning seat 2, and fixing blocks 202 respectively fixed to the top of the two positioning seats 2 and in contact with each other. A first support 203 corresponding to the slider 201 is mounted on the carrier 1 above the positioning seat 2, a return spring 204 fixed on the first support 203 and between the slider 201, and a disc 205 fixed on the side of the slider 201. The two discs 205 are fitted with adjustable height. The wedge block 301 and the first clamp 302 for driving the wedge block 301 to rise and fall are mounted on the carrier 1. The second support 3 is mounted on the carrier 1 near the positioning seat 2 for the wedge block 301 to slide. The third support 303 is mounted on the carrier 1 for the first clamp 302 to drive the wedge block 301 to move. The carrier 1 is mounted on the support 6. The shock absorber body 101 is located on the support 6. The carrier 1 is mounted on the fixed seat 5 near the support 6 and the second clamp 501 is mounted on the fixed seat 5.

[0027] In this embodiment, the wedge block 301 is driven to move downwards step by step by the first clamp 302. When the wedge block 301 moves downwards, it will generate a squeezing effect, causing the two discs 205 to move away from each other. The two sliders 201 will slide on the positioning seat 2 along with the movement of the two discs 205, and the sliding direction is away from each other. The two return springs 204 will be compressed, and the two sliders 201 will drive the two fixing blocks 202 to move away from each other until they abut against the inner ring of the lifting lug 103, thereby completing the fixing operation of the lifting lug 103.

[0028] Reference Figure 1 The carrier 1 is equipped with a go / no-go gauge 4 for detecting the height of the valve body. The detection mechanism includes a detection seat 7 installed on the edge of the carrier 1, a multi-directional detection frame 701 fixed on the detection seat 7, and a detection pin 702 for detecting the connector 102 and the valve body.

[0029] In this embodiment, the detection pin 702 is passed through the connector 102 and inserted into the multi-directional detection frame 701 to achieve precise positioning detection of the connector 102. The operator can hold the go / no-go gauge 4 to accurately detect the height of the valve body.

[0030] The implementation principle of the rapid welding point detection device based on the positioning of the shock absorber lug 103 in this application embodiment is as follows: the shock absorber body 101 is placed stably on the support 6, and the lug 103 is accurately fitted onto the outer periphery of the two fixing blocks 202. Next, the middle part of the shock absorber body 101 is fixed firmly with the help of the second clamp 501.

[0031] Subsequently, the wedge block 301 is driven to move downwards by the first clamp 302. When the wedge block 301 moves downwards, it will generate a squeezing effect, causing the two discs 205 to move away from each other. At the same time, the two sliders 201 will slide on the positioning seat 2 along with the movement of the two discs 205, and the sliding direction is away from each other. During this process, the two return springs 204 will be compressed.

[0032] As the above actions are performed, the two sliders 201 will drive the two fixed blocks 202 to move away from each other until they abut against the inner ring of the lug 103, thereby completing the fixing operation of the lug 103.

[0033] After completing the above fixing steps, the test pin 702 is passed through the connector 102 and inserted into the multi-directional test frame 701 to achieve precise positioning and testing of the connector 102. In addition, the operator can hold the go / no-go gauge 4 to accurately test the height of the valve body.

[0034] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0035] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
