[0005] Furthermore, one end of the measuring block is provided with a rectangular protrusion which is an integral structure therewith.

[0006] Furthermore, a pad is provided at the measuring hole on the rotary die.

[0007] Furthermore, the side plates and the rotating mold are provided with fixing holes for the fixing shaft to pass through.

[0008] Furthermore, the connecting block, the side plate and the guide block are an integrated structure.

[0009] Furthermore, the rotating mold and the side plate are hinged via a rotating shaft, and hinge holes for the rotating shaft to be inserted and pulled through are provided on the rotating mold and the side plate.

[0014] 4. The connecting block, side plate and guide block of the present invention are an integrated structure, which is convenient for taking and ensures the stability of the connection between them, and prevents the torsion spring from shifting due to loose connection between the connecting block, side plate and guide block when the torsion spring is fixed in conjunction with the rotating mold.

[0030] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1:

[0032] The fixed module group includes a fixed module and a rotating module 1. The fixed module includes a connecting block 2 and side plates 3 arranged on both sides of the connecting block 2. A concave platform 4 is provided on the inner side of the side plate 3 and is on the same horizontal plane as the connecting block 2. The rotating module 1 is placed in a U-shaped groove formed by the concave platform 4 and the connecting block 2, and one end of it is hinged to the side plate 3, and the other end is fixed by a fixed shaft 5 passing through the side plate 3 and the rotating module 1. An arc groove 6 is provided on the rotating module 1, and cooperates with the limit groove 7 provided on the connecting block 2 to form a fixed cavity for fixing the torsion spring A. A guide block 8 is provided on the connecting block 2, and a coaxial measuring hole 9 is provided on the guide block 8 and the rotating module 1, and the measuring block 10 is movably embedded in the measuring hole 9. The side plate 3 and the rotating die 1 are provided with fixing holes 11 for the fixed shaft 5 to pass through; the rotating die 1 is hinged to the side plate 3. After the torsion spring A is placed in the limiting groove 7 on the connecting block 2, the rotating die 1 is rotated, the rotating die 1 is transferred into the U-shaped groove, and fixed by the fixed shaft 5, so that the torsion spring A is fixed in the fixed cavity. It is convenient and quick to use, and solves the problem of displacement of the torsion spring A during measurement.

[0033] A rectangular protrusion 12 is provided at one end of the measuring block 10 as an integral structure therewith; the measuring block 10 is placed in different measuring holes 9, with the rectangular protrusion 12 resting on one side of the end of the torsion spring A, and the height exposed through the measuring hole 9 is measured; the measuring block 10 is rotated so that the rectangular protrusion 12 rests on the other side of the end of the torsion spring A and the height is measured; and the flatness of both sides of the end of the torsion spring A is obtained based on whether the heights are consistent. The operation is simple and the measurement is convenient.

[0034] A pad 13 is provided at the measuring hole 9 on the rotating mold 1; when the measuring block 10 moves in the measuring hole 9, the measuring block 10 drives the end of the torsion spring A to rotate and rest against the pad 13, and the curvature of the end of the torsion spring A is judged by whether the end of the torsion spring A matches the pad 13.

[0035] The connecting block 2, the side plate 3 and the guide block 8 are an integrated structure; while being easy to take out, the stability of the connection between them is ensured to prevent the torsion spring A from shifting due to the loose connection between the connecting block 2, the side plate 3 and the guide block 8 when the torsion spring A is fixed in conjunction with the rotating mold 1.

[0036] Example 2:

[0037] This embodiment is obtained by further describing the hinge method of the rotating mold 1 and the side panel 3 on the basis of the first embodiment. The remaining technical features are the same as those of the first embodiment, and the similarities are not repeated here. The hinge method is further as follows: the rotating mold 1 and the side panel 3 are hinged by a rotating shaft 14, and a hinge hole 15 is provided on the rotating mold 1 and the side panel 3 for the rotating shaft 14 to be inserted and removed.

[0038] The rotating mold 1 and the side plate 3 are hinged by a rotating shaft 14, and a hinge hole 15 is provided on the rotating mold 1 and the side plate 3 for the rotating shaft 14 to be inserted and removed. After the rotating shaft 14 is pulled out, the fixed mold and the rotating mold 1 can be detached. The split structure facilitates the replacement of damaged parts and improves utilization.

[0039] When in use, the fixing process of the torsion spring A is as follows: after hingedly connecting the rotating mold 1 to the side plate 3 through the rotating shaft 14, the torsion spring A is placed in the limiting groove 7 on the connecting block 2, the rotating mold 1 is rotated, the rotating mold 1 is turned into the U-shaped groove, and the fixing shaft 5 is passed through the fixing hole 11 for fixing, and the torsion spring A is fixed in the fixed cavity formed by the limiting groove 7 and the arc groove 6.

[0040] Curvature measurement process: The measuring block 10 is placed into the measuring hole 9 on the guide block 8. The end of the measuring block 10 (the end without the rectangular protrusion 10) is pressed against the end of the torsion spring A. The measuring block 10 is pressed to rotate the end of the torsion spring A and press it against the cushion block 13. The curvature of the torsion spring A end is determined by whether the torsion spring A end and the cushion block 13 are consistent.

[0041] Flatness measurement process: The measuring block 10 is placed in the measuring hole 9 on the rotating mold 1, the rectangular protrusion 10 on the measuring block 10 is pressed against one side of the end of the torsion spring A, and the height of the measuring block 10 exposed to the measuring hole 9 is measured. The measuring block 10 is rotated so that the rectangular protrusion 10 is pressed against the other side of the end of the torsion spring A and the height of the measuring block 10 exposed to the measuring hole 9 is measured. The flatness of both sides of the end of the torsion spring A is obtained based on whether the two measured heights are consistent.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
