Description

Technical Field

[0001] This utility model relates to the field of vibration damper testing technology, and in particular to an online testing fixture for quickly detecting the welding position of vibration dampers. Background Technology

[0002] Due to the thermal deformation characteristics of welded parts and the dimensional fluctuations of raw material components, the dimensions of various parts in the welded vibration damper will vary. We need to inspect the condition of the first piece before each day's production, and only proceed with production after it passes inspection. Furthermore, we need to conduct random checks on the quality of products on the production line at regular intervals to continuously monitor product quality, which requires the use of online monitoring fixtures.

[0003] In existing technologies, it is difficult to mark and inspect the helical points of the spring disc to check their correct position when inspecting vibration dampers, and there is no handheld go / no-go gauge for measuring the height of the valve body. Therefore, we propose an online inspection fixture for quickly inspecting the welding positions of vibration dampers to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology, which makes it difficult to mark and inspect the spiral points of the spring disc to check if the spiral points are in the correct position when inspecting the shock absorber, and also lacks the ability to use a handheld go / no-go gauge to inspect the height of the valve body. Therefore, this invention proposes an online inspection fixture for quickly inspecting the welding position of the shock absorber.

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

[0006] An online inspection fixture for rapidly detecting the welding position of a vibration damper includes an inspection mechanism for inspecting the vibration damper. The inspection mechanism includes a handheld go / no-go gauge and a spring clip for detachably mounting the handheld go / no-go gauge. The spring clip is mounted on a vibration damper carrier. The carrier is positionally adjustable in a first direction and a disc-type go / no-go gauge for inspecting the clearance surface of the vibration damper is mounted on the movable seat.

[0007] The marking mechanism includes a detection cylinder mounted on the movable base, a detection pin retractable within the first end of the detection cylinder, and a percentage measuring instrument rotatably mounted at the second end of the detection cylinder.

[0008] A positioning mechanism for fixing the shock absorber includes a clamp mounted along a first direction of the vehicle, a clamp block symmetrically sliding on the clamp for fixing the head of the shock absorber, and a clamp hinged to the vehicle for driving the clamp block to perform positioning work.

[0009] In a preferred embodiment, the shock absorber is equipped with a symmetrically connected connector with positioning holes, a spring disc mounted on the shock absorber, and a valve body inclinedly disposed on the shock absorber.

[0010] In a preferred embodiment, the carrier is fixedly provided with a support base having a V-shaped surface in a first direction, and a positioning base symmetrically fixed to the carrier with the support base as the midpoint. The positioning base is provided with a positioning pin that passes through the positioning hole to fix the connector.

[0011] In a preferred embodiment, the carrier is equipped with a calibration device for calibrating the height of the percentage meter.

[0012] In a preferred embodiment, the carrier is fixed with a guide rail for the sliding seat to slide.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. This solution effectively secures the tail, ends, and connecting parts of the shock absorber body through operations such as pushing the moving seat, pressing down the clamping blocks with clamps, and inserting the positioning pins into the positioning seats. This multi-part securing method prevents displacement or shaking of the shock absorber during assembly and testing, ensuring the accuracy and reliability of the operation;

[0015] 2. This solution can detect any abnormalities in the clearance surface by inspecting it, accurately control the height of the valve shell by inspecting its height, and accurately determine the position of the helical point and the height of the dial gauge by inspecting the position of the helical point, thus ensuring the elastic performance of the shock absorber.

[0023] 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.

[0024] Reference Figures 1-4 An online inspection fixture for quickly detecting the welding position of a vibration damper includes an inspection mechanism for inspecting the vibration damper 4. The inspection mechanism includes a handheld go / no-go gauge 201 and a spring clip 2 for detachably mounting the handheld go / no-go gauge 201. The spring clip 2 is mounted on a vibration damper 4 carrier 1. The carrier 1 is equipped with a movable seat 3 in a first direction, and a disc-type go / no-go gauge 301 for inspecting the clearance surface of the vibration damper 4 is mounted on the movable seat 3.

[0025] The marking mechanism includes a detection cylinder 5 mounted on a movable base 3, a detection pin 501 retractable within the first end of the detection cylinder 5, and a percentage measuring instrument 502 rotatably mounted at the second end of the detection cylinder 5.

[0026] The positioning mechanism for fixing the shock absorber 4 includes a clamp 6 installed along the first direction of the carrier 1, a clamp 601 symmetrically sliding on the clamp 6 for fixing the head of the shock absorber 4, and a clamp 602 hinged to the carrier 1 for driving the clamp 601 to perform positioning work. The shock absorber 4 is equipped with a connector 401 symmetrically connected with a positioning hole 402, a spring disc 404 installed on the shock absorber 4, and a valve shell 403 inclinedly arranged on the shock absorber 4.

[0027] In this embodiment, by pushing the movable seat 3, it slides smoothly along the guide rail 302 and gradually approaches the damper 4 until the tail of the damper 4 can pass smoothly through the movable seat 3. The disc go / no-go gauge 301 performs a detailed inspection of the gap surface of the damper 4, the handheld go / no-go gauge 201 on the spring clip 2 is removed, and the height of the valve body 403 is accurately measured.

[0028] Reference Figure 1 and Figure 4 The marking mechanism includes a detection cylinder 5 mounted on a movable base 3, a detection pin 501 retractable in one end of the detection cylinder 5, and a percentage gauge 502 rotatably mounted on the other end of the detection cylinder 5. A calibration component 9 for height calibration of the percentage gauge 502 is mounted on the carrier 1.

[0029] In this embodiment, the detection pin 501 will perform a marking detection operation on the spiral point of the spring disc 404 of the shock absorber 4 to confirm whether the position of the spiral point is accurate. At the same time, the calibration component 9 set on the carrier 1 will strictly detect the height of the percentage gauge 502 to ensure the accuracy and reliability of the measurement data.

[0030] Reference Figure 2 and Figure 3 The positioning mechanism for fixing the shock absorber 4 includes a clamp 6 installed along the first direction of the carrier 1, a clamp 601 symmetrically sliding on the clamp 6 for fixing the head of the shock absorber 4, and a clamp 602 hinged to the carrier 1 for driving the clamp 601 to perform positioning work. A support seat 7 with a V-shaped surface is fixed in the first direction of the carrier 1, and a positioning seat 8 symmetrically fixed in the carrier 1 with the support seat 7 as the midpoint. A positioning pin 801 is inserted into the positioning seat 8 through the positioning hole 402 to fix the connecting member 401.

[0031] In this embodiment, the clamp 602 applies downward pressure to cause the clamp block 601 to move on the clamp seat 6, thereby achieving a stable fixation of the end of the shock absorber 4. At this time, the positioning pin 801 is precisely passed through the positioning hole 402 pre-set on the shock absorber 4 connector 401 and inserted into the positioning seat 8 to ensure that the connector 401 is firmly fixed.

[0032] The implementation principle of the online inspection fixture for quickly detecting the welding position of a vibration damper in this application embodiment is as follows: During the assembly and inspection of the vibration damper, the vibration damper 4 needs to be accurately placed on the support seat 7 with a V-shaped surface. Then, by manually pushing the movable seat 3, it is made to slide smoothly along the guide rail 302 and gradually approach the vibration damper 4 until the tail of the vibration damper 4 can pass smoothly through the movable seat 3.

[0033] Next, the clamp 602 applies downward pressure to cause the clamp 601 to move on the clamp 6, thereby securing the end of the damper 4. At this time, the positioning pin 801 is precisely passed through the positioning hole 402 pre-set on the damper 4 connector 401 and inserted into the positioning seat 8 to ensure that the connector 401 is firmly fixed.

[0034] During the inspection process, the disc-type go / no-go gauge 301 equipped on the moving seat 3 will conduct a detailed inspection of the clearance surface of the shock absorber 4, while the handheld go / no-go gauge 201 is responsible for accurately measuring the height of the valve body 403. In addition, a special inspection pin 501 will perform a marking inspection operation on the helical point of the spring disc 404 of the shock absorber 4 to confirm whether the position of the helical point is accurate. At the same time, the calibration piece 9 set on the carrier 1 will strictly inspect the height of the percentage gauge 502 to ensure the accuracy and reliability of the measurement data.

[0035] 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.

[0036] 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.
