Description

Technical fields:

[0001] This utility model relates to the field of metal processing equipment technology, and more specifically to a testing fixture for a shock absorber tower. Background technology:

[0002] Currently, the shock absorber towers in automobiles are located in the engine compartment under the hood. Their main function is to install and fix the shock absorbers, while also supporting and stabilizing the vehicle body.

[0003] Existing shock absorber towers are formed by casting. After the casting is completed, the excess parts such as the gating system and risers on the outer side wall need to be machined. After machining, the wall panel of the corresponding side wall will deform, and the dimensions of the inner side wall of the wall panel will have a certain difference from the design dimensions. Therefore, it is necessary to inspect it after machining.

[0004] Existing testing equipment, such as Figure 1 As shown, the damper tower is placed on the base plate of the fixture. Multiple detection limit plates are fixed to the top surface of the side of the fixture's top plate. The dimensions of the processed tower are checked by inserting a go / no-go gauge into the gap between the detection limit plate and the corresponding outer wall of the damper tower. If the outer wall dimensions meet the requirements, it indicates that the inner wall dimensions also meet the requirements. However, it cannot directly detect the dimensions of the inner wall of the panel, limiting its detection effectiveness. Furthermore, the damper tower's internal cavity has positioning holes. Because the existing fixture places the damper tower directly on the base plate, the internal structure is not visible, making it impossible to accurately locate the positioning holes for detection. Multiple attempts are required to insert the top of the positioning post on the base plate into the corresponding positioning hole. Therefore, the detection effect of the existing fixture is very unsatisfactory, and the detection is difficult. Utility Model Content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a testing fixture for a shock absorber tower. It places the testing support frame into the inner cavity of the shock absorber tower for direct internal testing, resulting in good testing effect and high accuracy. Moreover, when installing the testing support frame, the protruding top rod can be inserted into the corresponding positioning testing recess for positioning testing, making testing convenient and effective.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A testing fixture for a vibration damping tower includes a vibration damping tower body, wherein a downwardly extending inner cavity is formed at the top center of the vibration damping tower body, and a plurality of positioning and testing recesses are formed inside the inner cavity.

[0026] For example, see below. Figures 1 to 9 As shown, a testing fixture for a shock absorber tower includes a shock absorber tower body 10. The top center of the shock absorber tower body 10 has a downwardly extending inner cavity, and the interior of the inner cavity has a plurality of positioning and testing recesses 111.

[0027] The upper section of the inner cavity is larger than the lower section. One side of the inner wall at the top of the inner cavity is formed with an outwardly extending horizontal wall surface. A first protrusion 11 is formed on the top surface of the extended wall surface. A downwardly extending positioning detection recess 111 is formed in the middle of the top surface of the first protrusion 11. A second protrusion 12 is formed on the other side of the inner wall at the top of the inner cavity. A downwardly extending positioning detection recess 111 is formed in the middle of the top surface of the second protrusion 12.

[0028] The detection support frame 20 is located in the upper part of the inner cavity. Multiple bottom positioning posts 21 are fixed on the bottom surface of the detection support frame 20. A protruding top rod 22 is fixed on the bottom surface of the bottom positioning post 21. The bottom of the protruding top rod 22 is inserted into the corresponding positioning detection recess 111, and its bottom end presses against the bottom surface of the corresponding positioning detection recess 111. A bottom positioning protrusion 13 is formed in the middle of the bottom surface of the inner cavity. The top surface of the bottom positioning protrusion 13 is a horizontal surface.

[0029] The first protrusion 11 is located at the left end of the front part of the inner cavity, the second protrusion 12 is located at the right end of the front part of the inner cavity, the wall panels on the rear and right sides of the inner cavity extend upward to form side extension plates, the bottom positioning posts 21 are fixed on the bottom surface of the left and right sides of the front part of the horizontal plate, and the extension connecting post 23 is fixed on the bottom surface of the middle part of the rear part of the horizontal plate.

[0030] Furthermore, an extension connecting post 23 is fixed to the center of the bottom surface of the testing support frame 20. A threaded through hole is formed in the center of the bottom end face of the extension connecting post 23. The screw part of the positioning post 24 is screwed into the threaded through hole, and the bottom end face of the positioning post 24 presses against the top surface of the bottom positioning protrusion 13. The positioning post 24 can be rotated as needed to adjust the position of its bottom end face to ensure that its bottom end face presses against the top surface of the corresponding bottom positioning protrusion 13.

[0031] In this embodiment, three-point support is used to ensure the stability of the position and the smooth placement of the detection support frame 20.

[0032] In this embodiment, the shock absorber tower body 10 is a product that has already undergone machining during testing.

[0033] Furthermore, the detection support frame 20 is a horizontal plate with multiple weight-reducing slots 25 formed on it. Its outer side wall corresponds to the inner side wall of the upper part of the inner cavity. At least two handles 26 are fixed on the top surface of the horizontal plate. The weight-reducing slots 25 reduce the weight of this embodiment, with a total weight of only about four kilograms, making it easy to handle and place. At the same time, the weight-reducing slots 25 can be used to observe the inner cavity of the shock absorber tower body 1 manually, making it easy to determine whether the positioning column 24 and the raised top rod 22 are installed in place, which is very convenient.

[0034] Multiple bent support members 27 are fixed on the top surface of the rear and right sides of the horizontal plate. The rear measuring strip 28 is fixed on the rear wall surface of all the bent support members 27 at the rear of the horizontal plate. The rear wall surface of the rear measuring strip 28 is close to and cooperates with the inner wall of the side extension plate at the rear side of the inner cavity. That is, the rear wall surface of the rear measuring strip 28 and the inner wall of the side extension plate at the rear side of the inner cavity are a contour structure to ensure the accuracy of the test.

[0035] A right measuring strip 29 is fixed on the right side wall of all the bent support members 27 fixed on the top surface of the right side of the horizontal plate. The right side wall of the right measuring strip 29 is close to and cooperates with the inner side wall of the side extension plate on the right side of the inner cavity. The right side wall of the right measuring strip 29 and the inner side wall of the side extension plate on the right side of the inner cavity are contoured to ensure the accuracy of the test.

[0036] The top left end of the side extension plate at the rear side of the inner cavity is formed with an upward and outward extending long extension piece 130. The top left end of the rear part of the horizontal plate is fixed with a reinforcing detection bending member 3. The rear wall of the upward extending rear bending detection piece 4 formed on the upper part of the reinforcing detection bending member 3 is close to and cooperates with the front wall of the long extension piece 130. The rear wall of the rear bending detection piece 4 and the front wall of the long extension piece 130 are contoured.

[0037] Multiple detection blocks 6 are fixed on the bottom surface of the front part and the bottom surface of the left side of the horizontal plate. The outer side wall of the detection block 6 is close to the rear wall of the front wall plate or the right side wall of the left side plate of the inner cavity and cooperates with the rear wall of the front wall plate or the right side wall of the left side plate.

[0038] In this embodiment, during testing, the protruding top rod 22 and positioning post 24 are first engaged with the top surface of the corresponding positioning detection recess 111 or bottom positioning protrusion 13 to check whether the positions of the positioning detection recess 111 and bottom positioning protrusion 13 are accurate. After successful placement, the following tests are conducted using go and no-go gauges: the rear wall of the rear measuring strip 28 is tested against the inner wall of the side extension plate at the rear side of the inner cavity; the right side wall of the right measuring strip 29 is tested against the inner wall of the side extension plate at the right side of the inner cavity; the rear wall of the rear bending detection piece 4 is tested against the front wall of the long extension piece 130; and the distance between the outer wall of the detection block 6 and the rear wall of the front wall plate or the right side wall of the left side plate of the inner cavity is tested. As long as the go gauge passes through and the no-go gauge fails to pass through, it indicates that the processing meets the requirements. The test is convenient, the test effect is good, and the test efficiency is greatly improved.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
