DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-21 , the present invention provides a technical solution:

[0035] A 360° rotating automobile torsion bar static pressure test fixture comprises a base plate 1, one end of which is connected to a worm gear reducer 3 via a rotating end pad 2, and the other end of which is connected to an L-shaped end seat 5 via a fixed end pad 4. The worm gear reducer 3 is equipped with a handwheel 6, and a circular scale plate 7 is installed on one side of the worm gear reducer 3. The output shaft 8 of the worm gear reducer 3 is key-connected to a connecting arm 9, and a pointer 10 adapted to the circular scale plate 7 is installed at one end of the connecting arm 9. The other end of the connecting arm 9 is detachably connected to a rotating end positioning block 11, and a plurality of L-shaped limit plates 12 are detachably connected to the rotating end positioning block 11. The L-shaped end seat 5 is detachably connected to a fixed end positioning block 13, and the fixed end positioning block 13 is detachably connected to an I-shaped limit plate 14. The rotating end positioning block 11 has a rotating end groove 15, and the fixed end positioning block 13 has a fixed end groove 16. A plurality of weight-reducing process holes 17 are opened in the middle of the base plate 1, and a plurality of handles 18 are detachably connected to one side of the base plate 1.

[0036] In this technical solution, the rotating end pad 2 and the fixed end pad 4 both play the role of adjusting the height. The height of the turbine reducer 3 and the L-shaped end seat 5 can be adjusted by adding, reducing or replacing the rotating end pad 2 and the fixed end pad 4. The turbine reducer 3 has a self-locking function, and the connecting arm 9 is connected to the output shaft 8 of the turbine reducer 3. During operation, the staff shakes the handwheel 6 to operate the turbine reducer 3 to realize the rotation of the output shaft 8, and the output shaft 8 drives the connecting arm 9 to rotate, and the rotating end positioning block 11 is connected to the end of the connecting arm 9.

[0037] In addition, when using the automobile torsion bar static pressure test fixture that can achieve a 360° rotation angle, when the user operates the turbine reducer 3 through the handwheel 6 to drive the connecting arm 9 to rotate, the pointer 10 on the connecting arm 9 rotates along with the connecting arm 9. The user can determine the rotation angle of the connecting arm 9 through the indication indicated by the pointer 10 on the circular dial 7 fixed on one side of the turbine reducer 3, thereby achieving the purpose of accurately operating the torsion bar rotation angle. The turbine reducer 3 with a self-locking function can achieve the purpose of self-locking the rotating end positioning block 11 at any angle during the rotation process, thereby ensuring the stability of the test operation. The handle 18 on the side of the base plate 1 serves to facilitate the transportation of this fixture.

[0038] In this embodiment, a plurality of adjustment long holes 19 and guide grooves 20 are provided at one end of the base plate 1, and the guide grooves 20 are adapted to the fixed end pad 4. A plurality of adjustment long holes 19 are also provided on the L-shaped end seat 5. The rotating end positioning block 11 has a mounting seat 21, and a mounting groove 22 is provided on one side of the mounting seat 21. The mounting groove 22 is adapted to the connecting arm 9. A plurality of connecting holes 23 and a limit plate hole 24 are provided on the rotating end positioning block 11. An axial hole 25 is provided at one end of the connecting arm 9, and the connecting arm 9 is key-connected to the output shaft 8 through the axial hole 25.

[0039] During the connection operation, the mounting groove 22 on the mounting seat 21 plays a positioning role. The rotating end positioning block 11 and the connecting arm 9 are both provided with a connecting hole 23. After the rotating end positioning block 11 is aligned with the connecting arm 9, the detachable connection between the rotating end positioning block 11 and the connecting arm 9 is completed through a threaded connection. The rotating end groove 15 on the rotating end positioning block 11 is used to cooperate with one end of the torsion bar. The L-shaped limiting plate 12 is detachably connected to the rotating end positioning block 11 through the limiting plate hole 24. Under the limiting action of the L-shaped limiting plate 12, one end of the torsion bar is fixed. The L-shaped end seat 5 is adapted to the adjusting long hole 19 on the base plate 1, and the adjusting length The design of hole 19 makes the matching position of L-shaped end seat 5 and base plate 1 adjustable, thus achieving the purpose of adjusting the distance between rotating end positioning block 11 and fixed end positioning block 13, so that this tool can be suitable for torsion bar test work of different lengths. The fixed end positioning block 13 cooperates with the adjustment long hole 19 on the L-shaped end seat 5. Such a design makes the height of the fixed end positioning block 13 adjustable, further broadening the scope of application of this tool. After the end of the torsion bar is aligned with the fixed end groove 16 on the fixed end positioning block 13, it is positioned by the I-type limit plate 14, thus completing the fixation of both ends of the torsion bar.
