Description

Technical Field

[0001] The present application relates to the field of flywheel processing, and in particular, to a flywheel fixture. Background Art

[0002] In order to improve production efficiency, the generator flywheel assembly will perform certain positioning and clamping on the flywheel body when processing the flywheel body. In different generators, the flywheel body has different sizes and models, and there are different clamping tools corresponding to them. In the continuous production process, each round of flywheel processing and production requires manual re-clamping of the flywheel body, that is, reinstalling different types of clamping tools to adapt to the flywheel body to be processed. In each debugging process, the clamping tool is installed as a whole on the processing machine tool, and the position of the clamping tool is ensured to correspond to other equipment on the processing machine tool, which greatly increases the work intensity of the workers, and consumes a lot of working time in the repeated disassembly and installation of the clamping tool, which significantly reduces the work efficiency and indirectly increases the production cost; at the same time, when processing the flywheel body, the general clamping tool is prone to loosening, resulting in a decrease in the flywheel processing accuracy, which in turn leads to an increase in the scrap rate of the flywheel body. Utility Model Content

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a flywheel clamp, including:

[0005] Base;

[0006] A positioning plate is arranged on the base;

[0007] A clamping member is provided on the positioning plate through and through, and one end of the clamping member extends and protrudes out of the base, and the clamping member is slidably matched with the base and the positioning plate;

[0008] A connecting plate, arranged on the positioning plate;

[0009] An opening is provided on the connecting plate, and the clamping member includes an elastic flaring structure for clamping the workpiece, and the elastic flaring structure passes through the opening; when the clamping member slides toward the base, the outer wall of the elastic flaring structure abuts against the inner wall of the opening.

[0010] The present application places the flywheel in the clamping groove, and moves the clamping member by means of an equipment processing machine tool, toward the base, so that the outer wall of the clamping groove of the clamping member abuts against the inner wall of the opening, thereby clamping the flywheel in the clamping groove.

[0011] Further, the clamping member comprises:

[0012] A driving rod, one end of which extends outside the base;

[0013] The elastic expansion structure is fixed on one end of the driving rod.

[0014] Furthermore, one end of the elastic expansion structure is constructed as a plurality of elastic clips, and there are gaps between the elastic clips.

[0015] Furthermore, one end of the elastic clip has an outward expansion portion, and one end of the inner wall of the opening has an expansion groove matched with the outward expansion portion.

[0016] Furthermore, the cross-sectional area of ​​the elastic clip gradually increases from one end to the other end, and the cross-sectional area of ​​the opening gradually increases from one end to the other end.

[0017] Furthermore, the clamping member further comprises:

[0018] A fixing ring, fixedly arranged on the inner wall of the driving rod;

[0019] A cone rod, fixed on the fixing ring;

[0020] One end of the tapered rod is inserted into the flywheel.

[0021] Furthermore, the clamping member further comprises:

[0022] A limiting plate, which is movably sleeved on the outer wall of the driving rod, and one end of which abuts against the side wall of the elastic expansion structure;

[0023] The return spring is arranged between the limit plate and the positioning plate.

[0024] Furthermore, a movable cavity for the limiting disk to slide is provided on the driving rod.

[0025] Furthermore, a mounting cavity for placing the limiting disk is provided on the positioning disk.

[0026] Furthermore, both the base and the positioning plate are provided with through slots for the clamping member to pass through.

[0027] The beneficial effect of the present application is that: the present application can realize synchronous processing of the pole claw and the tapered hole at one time through the cooperation of the elastic clip and the opening, and the action of the tapered rod, which greatly reduces the installation time and improves the size qualification and requirements of the flywheel product. To achieve the processing required by customers for product size, especially the processing requirements of the tapered hole, conventional flywheel clamping needs to be clamped and positioned through the tapered hole, but some customers have processing requirements for the flywheel tapered hole. In the past, the processing was to meet the customer's requirements for the processing of the tapered hole through secondary clamping, and the stability was poor and the concentricity was relatively low.
