Description
Technical Field
The utility model relates to a long section of thick bamboo thin wall type axle sleeve processingequipment belongs to machining technical field.
Background
The long-tube thin-wall type shaft sleeve has poor rigidity and weak strength, is extremely easy to deform in the machining process, is a key part of a vacuum pump, has high requirements on coaxiality and verticality, and has great influence on the machining quality and the working efficiency by the machining process and the clamping method. The traditional processing method comprises the following steps: the turning of one surface and two surfaces is completed by one-time clamping on a four-jaw chuck, and the key is that the turning of three surfaces and the fine turning of an excircle are processed by matching two ejector pins with a mandrel. The shaft sleeve has the advantages of complex processing technology, multiple working procedures, large accumulated error and low labor efficiency, and in addition, the processing precision and the one-time assembly qualification rate of parts are influenced due to the fact that different degrees of vibration occur in the processing process.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the long-tube thin-wall type shaft sleeve processing device is firm in clamping, reduces axial movement, and guarantees coaxiality and various form and position tolerances of a shaft sleeve.
Long section of thick bamboo thin wall type axle sleeve processingequipment, including positioning disk, locating component and clamp plate, locating component includes screw rod and nut, sets up the corresponding locating hole in position on positioning disk and the clamp plate respectively, the screw rod both ends are installed respectively in the locating hole, the nut is installed respectively in the positioning disk and the clamp plate outside, positioning disk and clamp plate all set up to protruding type structure, positioning disk root position periphery distributes has the mounting hole, the bulge periphery sets up the location step.
The positioning plate and the pressing plate are both provided with circular discs, and the positioning holes are respectively arranged at the central positions of the circular discs.
The positioning holes in the positioning plate are threaded holes, and the positioning holes in the pressing plate are through holes.
The mounting holes are four and are uniformly distributed on the periphery of the positioning plate.
The mounting hole is a countersunk hole.
When the lathe chuck clamping device works, the lathe chuck is used for positioning the machining device, the circular pressing plate is used, and the original clamping method of the ejector pin and the mandrel is replaced by a method of fastening by using the bolt. After the machining method is adopted, not only is the machining procedure of a grinding machine saved, but also the manual transfer time is reduced, and by the clamping method, the play generated during the machining of the mandrel is reduced, the machining precision of the shaft sleeve is ensured, and the working efficiency is improved. The method is firmer, reduces axial float and ensures the coaxiality and all form and position tolerances of the shaft sleeve.
The utility model has the advantages that:
the clamping method of the device reduces the play generated when the mandrel is used for machining, ensures the machining precision of the shaft sleeve and improves the working efficiency. The detachable disc chuck plane positioning tool is used, on the basis of improving the precision of a tool clamping fixture, a shaft sleeve machining reference surface is added, the clamping fixture is directly fastened on the clamping fixture through a pressing plate, the fastening is firmer, the shaft sleeve movement is reduced, and the form and position tolerance is guaranteed.
