In view of the problems existing in the processing of eccentric sleeves of cone crushers, how to develop and design a new type of special fixtures, using special fixtures to realize the processing of eccentric sleeves on the sleeping car, and to meet the requirements of product quality requirements, to meet the high quality of modern production. The production needs of the eccentric sleeve processing mechanism-cone crusher eccentric sleeve are independently designed and developed.
1. Power mechanism
The technology-conical crusher eccentric sleeve new processing fixture is to use an abandoned power mechanism (commonly known as power head) in the workshop, and the one end of the eccentric sleeve processing fixture is directly mounted on the chuck of the power mechanism, and the other section is The eccentric sleeve is supported and fixed by the bearing seat of the supporting mechanism, and the power is transmitted to the eccentric sleeve processing fixture clamped at the power end through the movement of the motor and the pulley of the power mechanism to realize the running function.
2, transmission mechanism design
The transmission part of the porcelain tooling tool uses a tooth difference gear mechanism to complete the locking of the differential motive groove through the clutch and the locking of the top wire during the machining process. The eccentric sleeve fixture starts to rotate under the action of the big head vehicle, in the top wire In the free state, the outside of the fixture rotates with the product, but does not form a feed; when the top wire is locked, the internal gear drives the pinion to start rotating.
3, walking mechanism
In the past, when using the car to turn the eccentric taper sleeve, it is not only necessary to use the hanging wheel and the machine tool to move the compound taper to process the compound taper, but also to design an ultra-long tool bar. Through the self-developed design of the eccentric sleeve new processing fixture, based on the inner cone surface of the eccentric sleeve, the mast is designed with the same taper as the taper sleeve, and the power mechanism and the support mechanism are used to enhance the rigidity of the mast, and then the power mechanism is utilized. Rotating, driving a gear difference gear mechanism in the transmission mechanism, the traveling mechanism mounted on the lead screw realizes the boring movement of the taper sleeve machining, effectively solves the knife knives and ensures the processing quality of the taper sleeve, and is a super long cone The set of processing provides valuable experience.
