Abstract
A cloth wheel chuck belongs to the technology field of polishing tool part, which comprises a middle joint whose two ends are respectively in cooperation connection with a rotary shaft and a cloth wheel connection rod. The middle joint is characterized in that steel balls are arranged in a through hole which is arranged on the middle joint shell body of the connection end of the cloth wheel connection rod. A convex ring which is in pressing cooperation with the steel balls is arranged on the corresponding position of the inner wall of a sleeve which is sleeved on the right end of the middle joint. A spring is in sleeve connection with the right side of the convex ring, and the convex ring is orientated via a blocking ring and clipping spring which are arranged on the outer end. An orientation groove which is in embedding cooperation with the steel balls is arranged on the corresponding position of the cloth wheel connection rod. The cloth wheel chuck has reasonable and simple structure. As the chuck is orientated by embedding cooperation via the steel balls and the orientation groove, and a multilateral cylinder structure is adopted by the cloth wheel connection rod, when the electric or pneumatic tool rotates at a high speed, the cloth wheel connection rod is locked tightly and is incapable to slip or depart from the middle joint, thus the utility model has the advantages of good clamping stability, safe and reliable use, and effectively increasing the working efficiency.

The utility model content
At the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that the firm cloth wheel chuck of a kind of clamping is provided, and it is safe in utilization, convenient.
Described a kind of cloth wheel chuck, comprise the center tap that two ends are connected with rotating shaft, cloth wheel connecting rod respectively, in the through hole that it is characterized in that being provided with on the center tap housing with cloth wheel connecting rod link steel ball is installed, the sleeve lining relevant position that is socketed in the center tap right-hand member is provided with and presses the protruding circle that cooperates with steel ball, the right side socket of protruding circle is provided with spring, and the baffle ring that is equipped with by the outer end, jump ring retaining connect the location, and the relevant position of cloth wheel connecting rod is provided with steel ball rabbets the locating slot that cooperates.
Described a kind of cloth wheel chuck is characterized in that the setting of center tap outer wall connects the rib that cooperates with the sleeve ends retaining.
Described a kind of cloth wheel chuck is characterized in that the draw-in groove that outer wall setting in center tap end cooperates with the jump ring clamping.
Described a kind of cloth wheel chuck is characterized in that the center tap jack that is connected with cloth wheel connecting rod is a polygon, and corresponding cloth wheel connecting rod cross section is a polygonized structure.
Described a kind of cloth wheel chuck is characterized in that the center tap jack that is connected with cloth wheel connecting rod is a hexagon, and corresponding cloth wheel connecting rod cross section is a hexagonal structure.
Described a kind of cloth wheel chuck is characterized in that center tap and rotating shaft threaded.
Above-mentioned a kind of cloth wheel chuck is skillfully constructed, and rational in infrastructure, simple, during normal condition, the protruding circle of sleeve lining presses with steel ball and cooperates; During use, the promotion sleeve makes it overcome spring force and moves, protruding circle and steel ball break away from, then cloth is taken turns connecting rod and insert in the center tap, unclamp sleeve, reset at spring force effect lower sleeve, the protruding circle of its inwall presses just with steel ball and cooperates, steel ball cooperates with the locating slot interlocking under protruding circle pressure, and cloth wheel connecting rod is stuck, and can operate; Repeat aforesaid operations when changing the cloth wheel and get final product, easy to use.And cloth wheel connecting rod adopts polygon column construction, and under electronic or situation that pneumatic tool rotates at a high speed, cloth wheel connecting rod is locked, and neither can skid also to be not easy and center tap breaks away from, and the clamping steadiness is good, and is safe and reliable, effectively improved operating efficiency.
