Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1, a quick installation fixture of numerical control lathe, including connecting 1, assembly body 2 and a support section of thick bamboo 3, assembly body 2 is the cylindric structure that one side has the inclined plane, and mounting groove 22 has been seted up to the opposite side outer peripheral face, and assembly body 2 passes through mounting groove 22 and numerical control lathe's main shaft flange joint, will drive assembly body 2 and rotate together when starting numerical control lathe's main shaft and rotating. The axis of one side of the assembly body 2 is provided with an outward-expanding tapered groove 21, the inner wall of the tapered groove 21 is a tapered surface, the axis of one side of the assembly body 2 is provided with a through hole 23 communicated with the tapered groove 21, the support cylinder 3 is a cylinder body with one side closed, the open end of the support cylinder is welded and fixed with the assembly body 2, and the through hole 23 is sealed in the inner cavity.
The joint 1 is arranged in the tapered groove 21, a gap is arranged between the joint 1 and the bottom of the tapered groove 21, the range of the gap is 2-8cm, the outer peripheral surface of the joint 1 is matched with the tapered groove 21, and therefore the outer peripheral surface of the joint 1 is also a tapered surface. The axle center of one end of the joint 1 is fixed with a plurality of bosses 11, the bosses 11 are of a cylindrical structure, the diameters of the bosses are in a step shape decreasing gradually in sequence, and the bosses with different diameters at the outer side of the joint 1 are used for sleeving grinding wheels with different clamping apertures. The grinding wheel processed here is a centreless grinding wheel specially used for processing magnets in the industry, a gland is added to fix the grinding wheel when the grinding wheel is sleeved, a threaded rod 12 is arranged at the end part of a boss 11, and the grinding wheel is screwed on the threaded rod 12 through a nut after being sleeved, so that the grinding wheel is further fixed firmly.
