Description

Hub bolt hole burring device Technical Field The utility model relates to the technical field of hub processing, in particular to a hub bolt hole deburring device. Background In the production and processing process of the hub, burrs are easily generated at the bolt hole parts due to the influence of cutting, stamping and other processes. The presence of these burrs presents a number of problems. From the assembly process perspective, burrs can prevent bolts from successfully passing through bolt holes, so that the bolts are difficult to install, and the assembly time and cost are increased. From the analysis of the service life of the hub, burrs cause stress concentration. However, the traditional manual deburring method is flexible to operate, but the existing manual tool and method have obvious defects. Operators typically use simple files, sandpaper, etc. tools to perform the deburring of the bolt holes by experience and hand. The mode is difficult to ensure that the removal force and the depth of each bolt hole are consistent, and the conditions of incomplete removal or damage to the surface quality of the bolt hole are easy to occur. Meanwhile, the operator can repeatedly and manually operate for a long time, the labor intensity is high, the efficiency is low, and the deburring effect of each bolt hole can be hardly guaranteed. Disclosure of utility model The utility model provides a hub bolt hole deburring device which has the beneficial effects that each bolt hole can be sufficiently deburred through manual operation. The utility model provides a hub bolt hole burring device, includes the base, encircles a plurality of clamping jaws of rigid coupling on the base, and the core rigid coupling of base has the dabber, still includes the handle, and the bottom surface of handle encircles a plurality of inserted bars of rigid coupling, and the handle passes through a plurality of inserted bars plug bush in the upper end of dabber, installs the slide on the handle, and the rigid coupling has the motor on the slide, and the output shaft of motor has the grinding roller through the coupling joint. The polishing roller is provided with a shaft sleeve, the bottom surface of the shaft sleeve is formed with a conical surface, and the radius of the cross section of the conical surface decreases from top to bottom. The shaft sleeve is connected with the polishing roller in a sliding manner, and the shaft sleeve is connected with the polishing roller in a detachable manner through a screw II. And a limiting ring is fixedly connected to the lower end of the shaft sleeve close to the conical surface. The polishing roller is provided with a prismatic groove.
