Description

Technical Field

[0001] The utility model relates to the technical field of assembly jigs, in particular to a torsion spring assembly jig. Background Technique

[0002] The torsion spring acts by torque and rotational force, so the stiffness of the spring should be strongly adjustable. Spring stiffness refers to the rotational torque generated at a fixed unit and angular position. If the spring stiffness is insufficient, the torque and rotational force will be insufficient. In addition, three points must be noted for the torsion spring: large deformation, large load, and standardized rotation direction. When the spring twists, the material is in a tensile or shear state, such as the calculation of the torsion degree mentioned. Therefore, the limit of the twistable angle is finally caused by the failure of the material. When the material undergoes plastic deformation, it cannot return to its original state.

[0003] However, the existing torsion spring assembly jigs have the following problems during use: When the traditional assembly jig is used, the operator needs to fix the primary part first, fix the ingot, and fix the position. In addition, it is inconvenient to remove the fixed position. Content of the Utility Model

[0004] The purpose of the utility model is to provide a torsion spring assembly jig to solve the related problems raised in the above background technique.

An activity slot is opened at the top of the positioning frame, and a second slide rail is arranged on the inner wall of the activity slot. A motor is arranged inside the positioning frame, and a lead screw is installed at the output end of the motor. A pressing frame adapted to the inside of the second slide rail is arranged on the outer wall of the lead screw, and a positioning block in contact with the outer wall of the spring workpiece is arranged on the inner wall of the pressing frame.

[0006] For the torsion spring assembly jig provided by this technical solution, the outer wall of the fixed frame is provided with a threaded layer, and the threaded layer is engaged with the groove inside the rotating main shaft.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1 is as follows Figure 1-2 As shown, the present utility model provides a technical solution: a torsion spring assembly jig, which includes a rotating main shaft 1, a spring processing part 2 and a positioning frame 3. The outer wall of the rotating main shaft 1 is wound with the spring processing part 2. A groove is opened on one side of the rotating main shaft 1, and a fixed frame 4 is arranged inside the groove. A positioning frame 3 is installed on one side of the fixed frame 4. A fixed slot 5 is opened inside the fixed frame 4, and a limiting mechanism for fixing the position of the positioning frame 3 is arranged inside the fixed slot 5. A threaded layer is arranged on the outer wall of the fixed frame 4, and the threaded layer meshes with the groove inside the rotating main shaft 1. The limiting mechanism includes a first slide rail 8 and an installation rack 9. The inner walls at both ends of the fixed slot 5 are installed with the first slide rail 8, and an installation rack 9 penetrating the rotating main shaft 1 is arranged inside the first slide rail 8. Tooth blocks are arranged on the inner wall of the installation rack 9. A fixed shaft 6 is installed inside the fixed slot 5 through a bearing, and a gear 7 meshing with the tooth blocks on the inner wall of the installation rack 9 is arranged on the outer wall of the fixed shaft 6. A rigid spring 10 is arranged inside the fixed slot 5, and one side of the rigid spring 10 is connected to the outer wall of the installation rack 9. By rotating the fixed shaft 6 to drive the gear 7 to mesh with the inner wall of the installation rack 9, the installation rack 9 is separated from the inside of the rotating main shaft 1, and then the positioning frame 3 is moved outwards, so that the fixed frame 4 is separated from the rotating main shaft 1. This structure is simple to operate and convenient to install.

[0021] Embodiment 2 is as follows Figure 1-3 As shown, the present utility model provides a technical solution: a torsion spring assembly jig, in which a movable slot 11 is opened at the top of the positioning frame 3, and a second slide rail 12 is arranged on the inner wall of the movable slot 11. A motor 13 is arranged inside the positioning frame 3, and a lead screw 14 is installed at the output end of the motor 13. A pressing frame 15 adapted to the inside of the second slide rail 12 is arranged on the outer wall of the lead screw 14, and a positioning block 16 in contact with the outer wall of the spring processing part 2 is arranged on the inner wall of the pressing frame 15. The inside of the pressing frame 15 meshes with the outer wall of the lead screw 14. By starting the motor 13 to drive the lead screw 14 to rotate, the lead screw 14 drives the pressing frame 15 to move at the position of the second slide rail 12, and then the pressing frame 15 drives the positioning block 16 to fit downwards with the outer wall of the spring processing part 2. Then the rotating main shaft 1 rotates and drives the position of the spring processing part 2 to be wound, which is convenient for the spring processing part 2 to be smoothly wound around the rotating main shaft 1.

[0022] Working principle: First, connect the external power supply, and then rotate the fixed shaft 6 to drive the gear 7 to rotate. As a result, the gear 7 meshes with the inner wall of the mounting rack 9, and then the mounting rack 9 retracts into the fixed groove 5 to squeeze the position of the rigid spring 10. Then, the operator can rotate the fixed frame 4 to mesh with the inner wall of the rotating main shaft 1. Next, release the position of the fixed shaft 6. Then, under the action of the self-elastic force of the rigid spring 10, the mounting rack 9 is driven to be fixed in the rotating main shaft 1, which is convenient for further stable installation of the positioning frame 3 and the rotating main shaft 1, improving the stability. The structure is simple to operate and convenient to disassemble;

[0023] When the spring workpiece 2 is wound around the rotating main shaft 1, since the previous position has not been fixed, the motor 13 can be started to drive the lead screw 14 to rotate. As a result, the lead screw 14 drives the pressing frame 15 to move at the second slide rail 12. Furthermore, the pressing frame 15 drives the positioning block 16 to move downward to fit with the outer wall of the spring workpiece 2. Then, while the rotating main shaft 1 rotates, it drives the spring workpiece 2 to be wound, which is convenient for the spring workpiece 2 to be smoothly wound around the rotating main shaft 1.

[0024] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
