Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of torsion spring testing tools, and particularly relates to a torsion spring testing tool with an anti - detachment structure. Background Art
[0002] A torsion spring, that is, a torsion spring, belongs to a helical spring. The ends of the torsion spring are fixed to other components. When the other components rotate around the center of the spring, the spring pulls them back to the initial position, generating torque or rotational force. The torsion spring can store and release angular energy or statically fix a device by rotating a lever arm around the central axis of the spring body. After the torsion spring is produced, it needs to be subjected to a torsion test to detect whether its quality meets the standard. However, most of the common testing tools for torsion springs do not have top - end limiting. During the test, the torsion spring will be subjected to a large external force for extreme testing. Under the action of a large force, it may break away from contact and fly out midway. Under the action of a large spring force, a large collision force may be generated, posing a potential safety hazard to the personnel around the tooling and causing collision damage to the surrounding equipment.
[0003] In summary, there are some problems in the use of torsion spring testing tools without an anti - detachment structure. Therefore, it is hoped to propose a new structure to solve the above - mentioned technical problems. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a torsion spring testing tool with an anti - detachment structure to solve the problems mentioned in the above background art.
[0005] The utility model is realized through the following technical solutions: A torsion spring testing tool with an anti - detachment structure includes: a tooling component, an anti - detachment pressure plate, and a torsion member. The tooling component consists of a tooling main body, an outer sleeve, and connecting screws. The lower end of the internal composition of the tooling main body is provided with a tooling bottom plate. The center of the upper surface of the tooling bottom plate is provided with a torsion spring placement column. An outer sleeve is arranged outside the torsion spring placement column, and the two are connected and fixed by connecting screws. The right end of the upper surface of the tooling bottom plate is provided with an anti - detachment seat. The left side of the anti - detachment seat is provided with an anti - detachment pressure plate for preventing the torsion spring from detaching during use. Above the anti - detachment pressure plate is a torsion shaft. Behind the torsion shaft is a connecting column. A slot is vertically formed through the upper surface of the connecting column. Inside the slot is a torsion member for driving the torsion spring to twist.
[0006] As a preferred implementation, a torsion seat is arranged above the torsion shaft. A torsion motor is arranged inside the torsion seat and is connected to the torsion shaft through a coupling. Above the torsion seat is a moving cylinder. The moving cylinder can drive the torsion seat to move up and down, and enable the torsion motor to drive the torsion member to rotate through the torsion shaft.
[0007] As a preferred embodiment, a bracket is provided above the moving cylinder and it has an integral structure with the tooling bottom plate. A retaining chute is formed at the left end of the upper surface of the retaining seat, and a retaining screw rod for driving the retaining pressure plate to move up and down is arranged inside the retaining chute.
[0008] As a preferred embodiment, a retaining slider is provided at the right end of the internal composition of the retaining pressure plate. A retaining threaded hole is vertically penetrated through the upper surface of the retaining slider, and the retaining slider is movably fitted with the retaining chute.
[0009] As a preferred embodiment, the retaining screw rod is in threaded fit connection with the retaining threaded hole. A pressure plate body for limiting and preventing the upper part of the torsion spring from disengaging is arranged on the left side of the retaining slider. When the retaining screw rod rotates and is screwed with the retaining threaded hole, the retaining slider can slide inside the retaining chute, so that the pressure plate body limits the upper end of the torsion spring to prevent it from disengaging.
[0010] As a preferred embodiment, a sleeve hole is vertically penetrated through the upper surface of the outer sleeve, and the sleeve hole is fitted with the torsion spring placement column;
[0011] Connecting threaded holes are formed on the outer side surfaces of the torsion spring placement column and the left end of the outer sleeve, and the connecting screw is in threaded fit connection with the connecting threaded hole.
[0012] As a preferred embodiment, mounting threaded holes are formed on the rear side surfaces of the connecting column and the torsion member. The upper end of the torsion member is fitted with the slot and is fixedly connected by screwing the mounting stud into the inner side of the mounting threaded hole. The upper end of the torsion member is fitted with the slot, and the mounting stud rotates inside the mounting threaded hole, so that the torsion member is fixedly connected with the connecting column, and thus different torsion members can be replaced according to actual tests.
[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: By adding a tooling component, a retaining pressure plate and a torsion member, the torsion spring is sleeved outside the outer sleeve. When the retaining screw rod is rotated to cooperate with the retaining threaded hole, the retaining pressure plate moves down to limit the top of the torsion spring. The moving cylinder drives the torsion seat to move down, the torsion motor drives the torsion shaft to rotate, and the connecting column drives the torsion member to perform a torsion test on the torsion spring, so as to achieve the effect of preventing disengagement. By adding a tooling component and a torsion member, the upper end of the torsion member is fitted with the slot, and the mounting stud rotates inside the mounting threaded hole, so that the torsion member is fixedly connected with the connecting column, and thus different torsion members can be replaced according to actual tests.

[0026] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a torsion spring test tooling with an anti - detachment structure, including: a tooling assembly 100, an anti - detachment pressure plate 200, and a torsion member 300. The tooling assembly 100 is composed of a tooling main body 101, an outer sleeve 102, and a connecting screw 103.
[0027] At the lower end of the internal composition of the tooling main body 101, there is a tooling bottom plate 101a. At the center of the upper surface of the tooling bottom plate 101a, there is a torsion spring placement column 101i. An outer sleeve 102 is arranged outside the torsion spring placement column 101i, and the two are fixedly connected by a connecting screw 103. At the right end of the upper surface of the tooling bottom plate 101a, there is an anti - detachment seat 101j.
[0028] On the left side of the anti - detachment seat 101j, there is an anti - detachment pressure plate 200 for preventing the torsion spring from detaching during use.

Above the torsion seat 101d, there is a moving cylinder 101c. The moving cylinder 101c can drive the torsion seat 101d to move up and down, and enable the torsion motor to drive the torsion member 300 to rotate through the torsion shaft 101e.
[0030] Above the moving cylinder 101c, there is a bracket 101b, which is an integral structure with the tooling bottom plate 101a.

Then, screw the connecting screw 103 into the inner side of the connecting threaded hole 102b to connect and fix the outer sleeve 102, so as to facilitate the test use of torsion springs of different specifications.
[0037] Mounting threaded holes 101g are provided on the rear side surfaces of both the connecting column and the torsion member 300.
