Problems solved by technology
Since the tire is flexible, not a rigid body, it cannot be cut on a lathe or the cutting can not reach the ideal level, so it is necessary to design an external expansion fixture to cut the tire after external expansion

Embodiment Construction
[0021] The specific embodiments of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.
[0022] Such as Figure 1 to Figure 3 As shown, the present invention provides a kind of crushing and stripping jig for waste automobile rubber tires. Customized large gear 8, several external expansion mechanisms evenly arranged on the mounting plate 3 around the lathe spindle 7. There are not less than three external expansion mechanisms, usually three to four, so that the waste tires can be expanded and fixed more evenly, and the waste tires can be prevented from being deformed and shaken during crushing and recycling.
[0023] The external expansion mechanism includes a driven gear and a sliding sleeve 11 installed on the mounting...

The invention provides a grinding and stripping clamp for a waste auto rubber tyre. The grinding and stripping clamp comprises a mounting plate, a customized gearwheel and a plurality of outward expanding mechanisms. The mounting plate is perpendicularly fixed on a lathe spindle. The customized gearwheel takes the lathe spindle as a shaft. The outward expanding mechanisms are uniformly arranged on the mounting plate around the lathe spindle. Each outward expanding mechanism comprises a driven gear, a sliding sleeve, a cam and a pushing rod. The driven gears and the sliding sleeves are mounted on the mounting plate. The cams are fixed together with the driven gears. The pushing rods are matched with the sliding sleeves in a sliding manner. The driven gears are meshed with the customized gearwheel. The sliding sleeves extend in the radial direction. A flat plate in contact with the corresponding cam is arranged at one end of each pushing rod. An expansion block of which the outer side is matched with the inner edge of the tyre is fixed at the other end of each pushing rod. The expansion blocks can jack the inner edge of the tyre to lift the tyre through the transmission of the gear mechanism and the cam mechanism, so that the tyre is fixed. A cam-gear transmission mechanism is adopted, is simple structure, easy to control and beneficial for production.
Description
technical field [0001] The invention belongs to the field of waste recycling, and relates to a jig for crushing and stripping waste automobile rubber tires. Background technique [0002] As automobiles gradually become the first engine driving domestic consumption, China is already facing serious environmental pollution problems caused by waste tires. According to incomplete statistics, China is the second largest tire producer in the world. As the national demand for cars soars, waste tires are also increasing year by year. [0003] In order to solve this problem now, adopt the method for lathe cutting to carry out the pulverization of tire at present. Because the tire is flexible, not a rigid body, it cannot be cut on a lathe or the cutting can not reach the ideal level, so it is necessary to design a kind of external expansion fixture, and then cut the tire after external expansion. Contents of the invention [0004] The technical problem to be solved by the present ...
