Technical Field

[0001] The utility model relates to the technical field of cutting and grinding of composite material winding products, in particular to a cutting and grinding tooling for a new type of composite material winding product. Background Technique

[0002] The rigid carbon fiber rod is a non-metallic product, with a hard and brittle texture, a small expansion coefficient, being able to withstand extremely cold and hot temperatures, not easily deformed, and the flexural strength becoming harder and more brittle as the temperature rises; during the production process of rigid carbon fiber winding products, end face cutting is also a very important process; however, it is very difficult for traditional tooling to achieve integrated cutting and grinding. Content of the Utility Model

[0003] The purpose of the utility model is to provide a cutting and grinding tooling for a new type of composite material winding product to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] A cutting and grinding tooling for a new type of composite material winding product, including a mandrel. The taper of the front and rear ends of the mandrel is 20 degrees, and expansion clamp parts are installed on the outer parts of the front and rear ends of the mandrel. Retaining rings are installed on the outer parts of the front and rear ends of the mandrel on one side of the expansion clamp parts, and lock nuts are installed on the outer parts of the front and rear ends of the mandrel on one side of the retaining rings.

[0006] As a further scheme of the utility model: The expansion clamp part includes an expansion clamp sleeve, and a plurality of expansion clamp grooves are evenly arranged inside the expansion clamp sleeve.

[0007] As a further scheme of the utility model: The expansion clamp sleeve is installed on the outer part of the mandrel.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model has little damage to the rim, high operation efficiency, low labor intensity, and no safety hazards; the expansion clamp sleeve makes the manufacturing and installation of the main engine parts simple, and the processing of the shaft and hole for installing the expansion clamp sleeve does not require high-precision manufacturing tolerances like interference fit; when installing the expansion clamp sleeve, no heating, cooling or pressurizing equipment is required. Only need to fit the tapered hole of the expansion clamp sleeve with the positive and negative cones of the shaft, and tighten with a locking nut according to the required torque, and the hub can be conveniently adjusted to the required position on the shaft.

[0010] The expansion clamp sleeve has a long service life and high strength. The expansion clamp sleeve relies on friction drive, has no keyway weakening for the connected parts, and there is no relative movement, so no wear will occur during work.

[0011] The expansion clamp sleeve is convenient to disassemble and has good interchangeability. Description of the Drawings

[0020] Please refer to Figures 1 to 7 , in the embodiment of the present invention, a cutting and grinding tooling for a new type of composite material winding product includes a mandrel 1. The taper of the front and rear ends of the mandrel 1 is 20 degrees, and expanding clamp parts 2 are installed on the outer sides of the front and rear ends of the mandrel 1. Retaining rings 3 are installed on the outer sides of the front and rear ends of the mandrel 1 on one side of the expanding clamp parts 2, and lock nuts 4 are installed on the outer sides of the front and rear ends of the mandrel 1 on one side of the retaining rings 3. The expanding clamp part 2 includes an expanding clamp sleeve 5. The expanding clamp sleeve 5 is installed on the outer side of the mandrel 1, and a plurality of expanding clamp grooves 6 are evenly opened inside the expanding clamp sleeve 5;

[0021] The expanding clamp sleeve 5 is used to internally support the composite material winding product 7 so as to fix the composite material winding product 7; the expanding clamp sleeve 5 is in contact with the mandrel taper of 20 degrees, and the expanding clamp grooves 6 are distributed 360 degrees in the expanding clamp sleeve 5; the retaining ring 3 is used to push the expanding clamp sleeve to move; the mandrel 1 is used for spindle clamping and positioning; the lock nut 4 and the mandrel 1 can be connected by threads. The lock nut 4 is used to lock the expanding clamp sleeve 5 to ensure that the rim and the tooling do not separate during rotation. When the lock nut 4 is tightened more and more, the expanding clamp sleeve 5 expands accordingly until the taper is fully matched and the lock nut 4 is locked to achieve the purpose of close fitting with the rim.

[0022] The working principle of the present utility model is as follows: When in use, the composite material winding product 7 is sleeved outside the mandrel 1, and then the expansion sleeve 5, the retaining ring 3, and the lock nut 4 are sequentially installed at both ends of the mandrel 1. The lock nut 4 is tightened to make the expansion sleeve 5 expand, so as to closely fit the composite material winding product 7, and then the composite material winding product 7 is fixed.

[0023] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
