Abstract

The utility model relates to a quick assembling and disassembling mechanism for a grinding wheel. The quick assembling and disassembling mechanism for a grinding wheel is characterized in that a grinding wheel shaft (5) is in the shape of a cone, and is inserted into a central through hole of a power shaft (14). A draw rod (15) is also arranged on the right part in the central through hole. The left end of the draw rod (15) and the right end of the grinding wheel shaft (5) are hooked. A pressure spring (19) is sheathed on the draw rod (15), and the draw rod (15) has the tendency of moving towards the right. A push rod (21) on the right end of the draw rod (15) is projected out the right end surface of the power shaft (14).

A grinding wheel is replaced once, only the time of a few of seconds is needed, which is convenient for operating workers.

Description

The quick assembling/disassembling mechanism of emery wheel

The utility model relates to a kind of machinery that stone material is carried out grinding.

In the prior art, in the grinding and process of the special-shaped lines of stone material, lace, a clamping of stone material will be through several operations such as corase grind, correct grinding, thick throwing, smart throwings, and the per pass operation all will be changed a kind of emery wheel, therefore will change emery wheel continually in the bruting process of a stone material.Traditional emery wheel is a solid shafting and at one end with the fixing emery wheel of screw or nut, all will unload loading nut or screw at every turn, and general each is two, three minutes, so replacing speed is slow and require great effort, and production efficiency is low.

The purpose of this utility model is to provide a kind of quick assembling/disassembling mechanism that can change the emery wheel of emery wheel fast.

The technical solution of the utility model is: a kind of quick assembling/disassembling mechanism of emery wheel, the emery wheel axle that emery wheel is housed is cone shape, the emery wheel axle of this cone shape is inserted in the center through hole left part of line shaft, described center through hole left part inwall is the taper shape identical with the tapering of emery wheel axle, and emery wheel axle and described center through hole left part inwall match; Right part also is provided with pull bar in the described center through hole, the right-hand member of the left end of this pull bar and emery wheel axle is clasp joint mutually, be with stage clip on the described pull bar, one end of this stage clip is connected with line shaft, the tendency that the other end is connected with pull bar and pull bar is had move right, the right-hand member of described pull bar is connected with the right side that push rod and this push rod protrude in line shaft, and the right side of described push rod is provided with the push rod toggle mechanism.

The utility model compared with prior art has following advantage:

After the emery wheel axle inserted in the center through hole of line shaft, the emery wheel axle that only need turn clockwise can be with the left end of the right-hand member of emery wheel axle and pull bar clasp joint mutually, and the emery wheel axle is fixed on the line shaft; When with the push rod toggle mechanism left during the push rod of top, the push rod pushing drawing rod is axially released at a left side emery wheel, rotates counterclockwise the emery wheel axle and just the emery wheel axle can be separated taking-up with pull bar, therefore changes the time that emery wheel only needs several seconds, has made things convenient for the operator.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is a structure cutaway view of the present utility model; Wherein:
