Description

A kind of external grinding gripping device

Technical field

This utility model is related to field of fixtures, specially a kind of external grinding gripping device.

Background technology

During production drill gun, hard alloy base is welded on drilling rod, needs to be ground outer bowlder on cylindrical grinder, because boring Have 120 ° of a V-groove on bar, traditional three-jaw or chuck all can not quick, simple clamping drilling rod, during such clamping Will generation efficiency it is low, the problems such as clamping is not firm.

Utility model content

The purpose of this utility model is to provide a kind of external grinding gripping device, to solve above-mentioned background technology in propose ask Topic.

For achieving the above object, this utility model provides following technical scheme：A kind of external grinding gripping device, including Mohs cone Handle, one group of end cap, end plate, one group of pinching screw, gripping block, V-block, the Morse taper shank is connected with one end of the end cap, The end plate is connected with the other end of the end cap, and the end cap leads to the Morse taper shank, the end cap and the end plate Cross soket head cap screw to be detachably connected, the gripping block and the V-block are arranged between the end cap, on the end cap Pinching screw is bolted with, the pinching screw on top coordinates with the V-block, and the pinching screw of bottom coordinates with the gripping block.

Preferably, circular hole is offered on the end plate.

Compared with prior art, the beneficial effects of the utility model are：When the external grinding gripping device is used, by upper and lower two ends The equal outward turning of pinching screw for covering so that the direction of gripping block and V-block to close end cap is moved, at this moment between two end caps Space become big, the drilling rod for welding is inserted in the space between two end caps by the circular hole on end plate, then pretension two Pinching screw on individual end cap, and the headstock of cylindrical grinder is rotated to drive this device, slowly rotate, knife is observed by dial gauge The direction of head skew, adjusts again two pinching screws until cutter head center is consistent with clamping frame center, now according to offset direction Locking pinching screw, completes the fixation of drilling rod, it is possible to which starting cylindrical grinder carries out Excircle machining；This device utilizes V-block Positioning principle, by the upper-lower position for adjusting V-block, reaches the mesh being maintained at drill gun cutter head on headstock for cylindrical grinding machine centrage , providing great convenience to grinding work, clamping is reliable and secure, simple to operate flexible.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Fig. 1-3 are referred to, this utility model provides a kind of technical scheme：A kind of external grinding gripping device, including Morse taper shank 1, One group of end cap 2, end plate 7, one group of pinching screw 4, gripping block 5, V-block 6, the Morse taper shank 1 connects with one end of the end cap 2 Connect, the end plate 7 is connected with the other end of the end cap 2, the end cap 2 and the Morse taper shank 1, the end cap 2 with it is described End plate 7 is detachably connected by soket head cap screw 3, the gripping block 5 and the V-block 6 be arranged at the end cap 2 it Between, the pinching screw 4 is bolted with the end cap 2, pinching screw 4 and the V-block 6 on top coordinate, the folder of bottom Tight screw 4 coordinates with the gripping block 5, and circular hole 8 is offered on the end plate 7.

Operation principle：When using the external grinding gripping device, by the equal outward turning of pinching screw 4 on upper and lower two end caps 2 so that , to moving near the direction of end cap 2, at this moment the space between two end caps 2 becomes big, by the brill for welding for gripping block 5 and V-block 6 Bar is inserted in the space between two end caps 2 by the circular hole 8 on end plate 7, then the pinching screw on two end caps 2 of pretension 4, and the headstock of cylindrical grinder is rotated to drive this device, slowly rotate, the direction of cutter head skew is observed by dial gauge, according to Offset direction adjusts again two pinching screws 4 until cutter head center is consistent with clamping frame center, now locks pinching screw 4, complete Into the fixation of drilling rod, it is possible to which starting cylindrical grinder carries out Excircle machining.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
