Abstract
The utility model discloses a handheld grinding wheel dismounting tool which comprises a sleeve; four rectangular clamping columns are arranged on the ring-shaped end surface of the sleeve; the widths of the rectangular clamping columns in the radial direction of the sleeve are a half of the thickness of the side wall of the sleeve; the clamping columns are uniformly distributed on the ring-shaped end surface; one side surface of each of the clamping columns is communicated with the outer wall of the sleeve; two rotating arms extending downwards in the axial direction of the sleeve are arranged on the sleeve, and are cylindrical; and the axes of the two rotating arms are positioned on the same straight line. After a grinding wheel disk is fixed, an opened end of the sleeve is placed on the axis of a grinding wheel disk, and the clamping columns are clamped on a clamping ring on the axis, so that the rotating arms rotate around the axis of the sleeve to loose nuts mounted on the rotating arms, the cylindrical rotating arms have no edges and corners to avoid scratching to palms; ball heads are mounted at the tail ends of the rotating arms to increase the contact area between the palm and the rotating arms to facilitate the rotation, reduce the pressure stressed on the palm, and enhance the comfort level of the palm.
Description
Technical field
The utility model relates to the extracting tool of cutlery manufacturing procedure medium plain emery wheel, specifically is meant the extracting tool of hand-held emery wheel.
Background technology
Cutlery is the instrument that is used for carrying out cut, mainly refers to lathe tool, reamer; Planing tool, drill bits etc. mainly contain two types from the material differentiation: carbide alloy, quenching steel; Common cutlery all is that carbide alloy is whole as cutlery; Advantage is to use the time long, and shortcoming is that cost is too high, and carbide alloy can not utilize fully; Also having a kind of is by the essential part of quenching steel as cutlery, and by the blade of carbide alloy as cutlery, advantage is that cost is low, and shortcoming is to use the life-span short, and anti-wear performance is poor, and processing technology is complicated, and success rate is lower.The manufacturing process of cutlery mainly contains: select materials, blanking, preliminary working, fine finishining, finished product cleaning, detection, packing etc.Wherein preliminary working and fine finishining comprise car, mill, technology such as boring, brill, mill.Milling machine is mainly processed the lathe on various surfaces on workpiece with milling cutter.Usually milling cutter rotatablely moves and is main motion, and moving of workpiece and milling cutter is feed motion, and it can processing plane, groove, also can process various curved surfaces, gear etc.Milling machine is the lathe that workpiece is carried out Milling Process with milling cutter.Outside milling machine decapacitation milling plane, groove, the gear teeth, screw thread and the splined shaft, can also process the profile of more complicated, efficient is high than planer, is used widely in machine-building and repairing department.In the unloading process of abrasive disc, because emery wheel and axis are through snap fit be threaded, after emery wheel work; Being connected between emery wheel and the axis is very tight, be difficult for it is split, and; Coupling part such as emery wheel, axis is cylindrical; Its surface is smooth usually, under the effect of external force, can rotate arbitrarily, and the difficulty of dismounting is very big.
The utility model content
The purpose of the utility model is to provide a kind of extracting tool of hand-held emery wheel, overcomes emery wheel and is difficult to the problem that splits and assemble, improves emery wheel dismounting efficient.
The purpose of the utility model realizes through following technical proposals:
The extracting tool of hand-held emery wheel; Comprise sleeve, sleeve inner is a cavity structure, and the one of which end opening has circular end face; The circular end face of said sleeve is provided with four rectangular-shaped card posts; The width that cuboid card post directly makes progress at sleeve is the half the of sleeve lateral wall thickness, and said card post is evenly distributed on the circular end face, and a side of card post is communicated with the outer wall of sleeve; Sleeve is provided with two along its axial outward extending cursor, and two cursors are cylindrical and its axis is located along the same line.Sleeve is cylindrical, and its inside is cavity structure, and an end of sleeve has circular end face; Extend at end face the side of sleeve, and protrude from four rectangular-shaped card posts of end face formation, and the width that the card post directly makes progress at sleeve is the half the of annulus end surface thickness; The card post is evenly distributed on the annulus of end face the one-tenth center symmetry of four card posts about the axis of sleeve, and the sidewall of sleeve is provided with two cursors, and cursor is cylindrical; The axis of two cursors is located along the same line, and the axes intersect of its axis and sleeve, during use; With abrasive disc fixing after, the openend of sleeve is placed on the axis of abrasive disc, with the fastening of card post on the snap ring of axis; Make cursor rotate and can nut mounted thereto be unclamped around the axis of sleeve, columniform cursor does not have corner angle, avoided palm scuffing.
The circular end face of said sleeve caves inward and forms four hole clippings along being parallel to the sleeve axis direction; The side of said hole clipping is communicated with the internal cavities of sleeve; Said four hole clippings are evenly distributed on the circular end face of sleeve, and any two adjacent card posts are about the sleeve diameter symmetry at the place of the hole clipping between two card posts.As the further improvement of the utility model, the end face at card post place is provided with four hole clippings, and hole clipping distributes with the card post; Distance between the card post that any hole clipping is adjacent is all identical, and hole clipping caves inward along the direction that is parallel to sleeve axis, and hole clipping has opening on sleeve lining; So; Be convenient to the protrusion piece on the grinding wheel spindle is inserted in the hole clipping, further increase the arm of turning round between grinding wheel spindle and the sleeve, be convenient to the dismounting of emery wheel.
End at said cursor is provided with bulb.As the further improvement of the utility model, at the end of cursor bulb is installed, can help rotation with increasing the contact-making surface of palm with cursor, reduced the pressure that palm receives, increased the comfort level of palm.
The utility model compared with prior art has following advantage and beneficial effect:
The extracting tool of 1 the utility model hand-held emery wheel; With abrasive disc fixing after; The openend of sleeve is placed on the axis of abrasive disc, on the snap ring of axis, makes cursor rotate and can nut mounted thereto be unclamped around the axis of sleeve with the fastening of card post; Columniform cursor does not have corner angle, avoided palm scuffing;
The extracting tool of 2 the utility model hand-held emery wheels, hole clipping distributes with the card post, and the distance between the card post that any hole clipping is adjacent is all identical; Hole clipping caves inward along the direction that is parallel to sleeve axis; Hole clipping has opening on sleeve lining, so, be convenient to the protrusion piece on the grinding wheel spindle is inserted in the hole clipping; Further increase the arm of turning round between grinding wheel spindle and the sleeve, be convenient to the dismounting of emery wheel;
The extracting tool of 3 the utility model hand-held emery wheels is equipped with bulb at the end of cursor, can help rotation with increasing the contact-making surface of palm with cursor, has reduced the pressure that palm receives, and has increased the comfort level of palm.
