Description

Technical Field

[0001] This utility model belongs to the field of torsion spring manufacturing, and in particular relates to a torsion spring torsion arm auxiliary device. Background Technology

[0002] A torsion spring is an elastic mechanical component used to control the movement of machine parts and to dampen impacts or vibrations. It is widely used in industries such as instrumentation and machinery manufacturing. When a torsion spring is in operation, its torsion arm bears the stress caused by the torsion of the spring, making it the most vulnerable point to breakage. Therefore, special attention must be paid to the surface quality of this area during production, and obvious scratches are not permitted.

[0003] Traditional torsion spring torsion arm manufacturing involves calculating the number of torsion spring coils, cutting and winding the spring coils onto a single piece of material, and pre-reserving the required length of the torsion arm at both ends. This method of torsion spring manufacturing is inefficient and produces inconsistent quality, suitable only for single-piece or small-batch production, and cannot meet the needs of mass production. To solve the problems of low production efficiency and inconsistent quality caused by the torsion spring torsion arm manufacturing process, a reasonably designed auxiliary device for manufacturing torsion spring torsion arms is provided. Utility Model Content

One end of the insert block 5 is fixed to the side of the torsion disc 2, and the other end is set as a bent part corresponding to the notch of mandrel 4.

[0009] The torsion spring to be processed is sleeved on the upper end of the mandrel 4, and the end of the torsion arm at its bottom is fixed to the bent part of the insert block 5; by rotating the wrench 6, the insert block 5 on the torsion plate 2 is rotated, thereby pulling out the torsion arm to be processed.

[0011] Furthermore, the mandrel 3 is arranged from top to bottom as square segment 1, cylindrical segment, square segment 2, and threaded segment.

[0012] Furthermore, the twisting disc 2 has a slot on its side for fitting the insert block 5, and its top is provided with a threaded hole that communicates with the slot on the side for screwing in a bolt to fix the insert block 5.

[0013] Furthermore, the center of the twisting disc 2 is provided with a square hole for engaging with the square segment of the spindle 3.

[0014] Furthermore, the cylindrical section of mandrel 3 is rotatably connected to the through hole on the right side of the fixing plate.

[0015] Furthermore, the square segment 2 of the mandrel 3 mates with the square hole of the wrench.

[0016] Furthermore, the threaded section of mandrel 3 mates with the nut washer to fix the axial position of mandrel 3.

[0017] Furthermore, the upper end of the spindle 4 is set as a smooth cylinder to hold the torsion spring, and the lower end is provided with external threads to cooperate with the nut, washer and fixing plate 1 for fixation.

[0018] Furthermore, a vise is provided on the workbench.

[0019] Furthermore, the vise is used to clamp the clamping part.

[0035] Plug: such as Figure 6 There is 1 piece in total. The plug is assembled to the slotted part on the side of the twist plate. The side end face is tightened and fixed with hexagonal bolts to make it firm.

[0036] wrench: such as Figure 7 There is 1 piece in total. The square hole of the wrench is matched with the mandrel. The function of the wrench is to rotate the mandrel to drive the torque plate and plug to rotate and pull the torque arm.
