Abstract

The invention relates to a special clamping device for a chuck of a machine tool. The special clamping device for the chuck of the machine tool consists of a handle (1), a wrench (2) with a step, screws (3), end caps (4), a spring (5) and a shaft sleeve (6). The step is added in the middle of the common chuck wrench, the step and the lower part of the wrench are mounted in the shaft sleeve, the spring is mounted between the lower part of the step of the wrench and the bottom of the inside of the shaft sleeve, when the wrench is pressed downwards, the pressure overcomes the effect of the elastic force of the spring so that the lower part of the wrench extends out of the shaft sleeve and is inserted in a small hole of the chuck to operate; and after operation is finished, the pressure disappears, the lower part of the wrench leaves away from the small hole of the chuck under the effect of the elastic force of the spring and retracts into the shaft sleeve, and the whole wrench is separated from the chuck.

Description

A kind of clamping device
Technical field
The present invention relates to a kind of machine chuck special spanner operation safety problems, can prevent machine chuck from pulling Hand flies out from chuck and produces security incident, is effectively protected operator's personal safety and equipment safety.
Background technology
Machine tool chuck wrench is instrument conventional during machine operation, as improper use can occur safe thing Therefore.On the three-jaw or chuck of lathe with conventional spanner clamping, unclamp workpiece time, when spanner is too late Time when taking off from chuck, if chuck rotates after starting lathe, spanner is thrown away by tangential direction, easily hurts sb.'s feelings Or hinder thing, or spanner can not throw away in time and block chuck and damage lathe, these situations for beginner or Person student is machined out during training often occurring.Based on above-mentioned situation, a kind of chuck special spanner of design, Can not stay on chuck when not using, be avoided that the security incident caused because of chuck handle improper use.
Summary of the invention
It is an object of the invention to provide a kind of machine chuck special spanner, chuck when not using, can not be stayed On, it is avoided that the security incident caused because of chuck handle improper use.
The technical solution used in the present invention is: it is by handle (1), spanner with the level (2), screw (3), End cap (4), spring (5) and axle sleeve (6) composition.In the middle part of conventional chuck handle, increase by a step, step and The lower part of spanner is arranged in axle sleeve, installs a spring between spanner step bottom and axle sleeve inner bottom part, when When spanner is by downward pressure, pressure overcomes the elastic force effect of spring to make spanner bottom stretch out axle sleeve, inserts Enter in chuck aperture and operate；After operation terminates, distress resolves, spanner bottom is in the elastic force effect of spring Under leave in chuck aperture retraction axle sleeve, whole spanner depart from chuck.
The invention has the beneficial effects as follows: when using this special spanner clamping and unclamping workpiece, firmly will gently In the aperture of spanner working position press-in machine chuck, turning handle, the clamp of chuck outwardly or inwardly moves, When not using machine chuck special spanner, in special spanner under the effect of elastic force by spanner working position from Ejecting in chuck aperture, it is to avoid spanner continues to stay on chuck, machine chuck rotates will not occur security incident.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention
In Fig. 1,1, handle；2, spanner with the level；3, screw；4, end cap；5, spring；6, Axle sleeve.
Detailed description of the invention
The present invention is by handle (1), spanner with the level (2), screw (3), end cap (4), spring (5) and Axle sleeve (6) forms.Shock mount (5) between the step of axle sleeve (6) and spanner with the level (2), it is ensured that band platform Spanner (2) bottom on rank can easily be inserted axle sleeve (6) and be gone to the bottom central through hole, spanner with the level (2) Step upper end be inserted in end cap (4), end cap (4) is connected with axle sleeve (6) upper surface by screw (3), Spanner (2) step and step are pressed in the hole of axle sleeve (6) by end cap (4) with lower part and spring, it Form a whole.

Claims (1)

1. a machine chuck Special clamping device, it is by handle (1), spanner with the level (2), spiral shell Nail (3), end cap (4), spring (5) and axle sleeve (6) composition.It is characterized in that in the middle part of conventional chuck handle The lower part increasing a step, step and spanner is arranged in axle sleeve, spanner step bottom and axle sleeve inner bottom part it Between a spring is installed, when spanner is by downward pressure, pressure overcomes the elastic force effect of spring to make spanner Axle sleeve is stretched out in bottom, inserts in chuck aperture and operates；After operation terminates, distress resolves, spanner bottom Leaving in chuck aperture retraction axle sleeve under the elastic force effect of spring, whole spanner departs from chuck.
