Description

A kind of Pressure gauge table circle dismantling device

Technical field

The utility model relates to a kind of machine tool, particularly a kind of Pressure gauge table circle dismantling device.

Background technology

All be that method through elasticity table circle is installed on watchcase seals the movement of watchcase inside at present at the spring-tube type of mechanical industry extensive use or vacuum type Pressure gauge; In order to reach better sealing effectiveness; The draw-in groove of 3-4 band slope all can be set in the outside installation place of watchcase usually; The clamp that matches in the correspondence position setting of table circle stretches into corresponding draw-in groove respectively with clamp during installation and rotates to an angle can will show to enclose again and be in place.When the table circle that uses said method to install because reasons such as maintenance need dismantle the time; Owing to do not have special instrument, often cause the damage of table circle and watchcase, even Pressure gauge is scrapped because of misoperation; Same owing to do not have proper tools, the table circle of pulling down to reinstall also very difficulty.China national Department of Intellectual Property discloses the utility model patent (notification number: CN 201461576U of a kind of " hydraulic mechanism control valve sealing ring attaching/detaching apparatus " by name; The day for announcing: 2010-05-12); Content is: a kind of sealing ring attaching/detaching apparatus of hydraulic mechanism control valve; Comprise stage clip device, bolt, the nut that matches with bolt, be provided with coaxial ladder circular hole in the said stage clip device, bottom macropore internal diameter matches with the control valve upper end; On the tube wall of macropore from the bottom to being provided with square through hole, the upper end aperture matches with bolt; The screw with the control valve top of said bolt matches.This utility model can only be applicable to the dismounting of the valve sealing ring of some specification, for the dismounting of the table circle of one type on Pressure gauge and inapplicable.

The utility model content

The purpose of the utility model is to solve because the Pressure gauge table circle that does not have specific purpose tool to cause is difficult to the problem dismantling and reinstall, and a kind of novel Pressure gauge table circle extracting tool is provided.

For achieving the above object; The utility model adopts following scheme: a kind of Pressure gauge table circle dismantling device, comprise handle, and said handle front end is equipped with the steel wire rope of ring-type; One end of said steel wire rope is fixed on the steady pin of handle front end one side; The other end is fixed on the tightening system in the handle, is socketed with some fixture blocks on the said steel wire rope, has a screw that penetrates into steel wire rope on each fixture block; The another side relative with screw is provided with a convexity on the fixture block, and the profile of the clamp in the said convexity and the Pressure gauge circle outside is complementary.After with instrument watchcase being fixed earlier during dismounting table circle; Fixture block is moved to the position corresponding with the clamp of showing to enclose and convexity is stretched in the clamp along steel wire rope; Screw is screwed into screw is fixed on the steel wire rope fixture block; Utilize tightening system with steel wire rope banding table circle, make the clamp of table circle move to the position of corresponding watchcase draw-in groove, can will show circle and pull down along the opening direction turning handle; When reinstalling the table circle, stretch in the draw-in groove of watchcase as long as will show the clamp of circle earlier, the convexity of fixture block is inserted in the clamp again, other operations are identical with dismounting,, can will show circle and install to certain angle along the installation direction turning handle.

As preferably, said tightening system comprises a runner, and the edge indent of said runner forms steel wire rope groove, and an end of said steel wire rope is fixed in the steel wire rope groove, and the two ends of the runner shaft of said runner stretch out in outside the handle.Can realize the folding and unfolding of runner through the runner shaft rotating wheel to steel wire rope; And control the size of steel wire rope annulus with this; Not only can make the utility model be used for the Pressure gauge of various bores; And can tighten up or loosen steel wire rope according to action need, more laborsaving efficient when making the utility model operation.

As preferably, the opposite side that said handle front end is positioned at steady pin is provided with two spacer pins, and said steel wire rope passes between two spacer pins.Can control the trend of steel wire rope so better, help to keep the shape of steel wire rope.

As preferably, an end of said runner shaft is provided with the rocking arm vertical with runner shaft.Come the rotating wheel axle through rocking arm, more laborsaving in the time of can making operation.

The beneficial effect of the utility model is: can low weight loose ground dismounting Pressure gauge table circle, avoided since dismounting improper cause to the damage of Pressure gauge with the table circle, and compact conformation, easy and simple to handle.
