Abstract
The utility model discloses a special device for assembling and disassembling a valve core, which comprises a ball screw, a screw sleeve and a reference plate; the reference plate is fixed on the end of the screw sleeve, and the reference surface of the reference plate is vertical to the axis of the screw sleeve; the screw sleeve is screwed on the ball screw; one end of the ball screw extends out of the screw sleeve and the reference plate and is matched with the reference surface with spacing, and the end thereof is provided with a thimble; and the other end of the ball screw extends out of the screw sleeve, and the end thereof is a driving end. When the device is used, a valve body and the reference plate are fixed, the reference surface of the reference plate is fitted on the reference surface of the end surface of the valve body, the thimble is in alignment with the valve core in the valve body, the driving end rotates the ball screw to vertically push out or press in the valve core, thereby improving the valve core assembling or disassembling concentricity, and preventing the surface of the valve core from being worn and leaking; and in addition, the reference plate is horizontally positioned, the ball screw vertically moves, thereby improving the valve core assembling or disassembling repairing precision, and prolonging the service life of the valve body.
Description
Technical field
The device that the utility model uses when relating to a kind of spool installation or removal relates in particular to a kind of device that is exclusively used in the spool mounting or dismounting.
Background technology
Along with the universal use of hydraulic test, the hydraulic valve on the hydraulic test occupies very large proportion.Especially in metallurgy industry, the hydraulic valve that various installation accuracies are high just has good hundreds of kind specification.In regular maintenance, always run into that spool is stuck, card slag, spring toughness deficiency, change seal spool or the like, need the installation and removal spool.
In the prior art, do not use and be used for the specific purpose tool of spool installation or removal at the production scene, the maintenance technician is when dismounting spool or installation spool, only beat with hammer with the sensation of oneself, the stuck easily and wearing and tearing of spool, installation accuracy is low, easily causes in the hydraulic valve and lets out, service behaviour reduces greatly, and has shortened the service life of valve.
The utility model content
At the prior art above shortcomings, the utility model provides a kind of stuck and wearing and tearing of spool of avoiding, and improves installation accuracy and service behaviour, prolongs the valve device that is exclusively used in the spool mounting or dismounting in service life.
The device that is exclusively used in the spool mounting or dismounting that the utility model provides comprises ball screw, screw mandrel sleeve and datum plate; Described datum plate is fixedly installed on the end of screw mandrel sleeve, the axis normal of the datum level of datum plate and screw mandrel sleeve; Described screw mandrel sleeve rotation set is on ball screw; One end of described ball screw stretch out screw mandrel sleeve and datum plate and with the datum plate matched in clearance, its end is a thimble, the other end of ball screw stretches out the screw mandrel sleeve, its end is a drive end.
Further, the barrel top of described screw mandrel sleeve is provided with oil filler point, and described oil filler point is communicated with gap between ball screw and the screw mandrel sleeve; Described ball screw is sealed and matched by sealing ring and datum plate;
Further, described screw mandrel sleeve is set with application of force gripper shoe near an end of drive end, described ball screw pass application of force gripper shoe and with application of force gripper shoe matched in clearance.
The beneficial effects of the utility model: when using this device, valve body to be installed or dismounting is fixed on the metalworker's vice, the datum level of datum plate is fitted on the datum level of valve body end face, the thimble of ball screw is aimed at the spool in the valve body, and datum plate is fixed on the metalworker's vice, vertically spool is ejected or vertically spool is pressed into by drive end swing roller screw mandrel, improve the concentricity of spool installation or removal, avoid the spool face wearing and tearing and the generation leakage; And datum plate employing horizontal location, the mode that ball screw moves both vertically is worked, and improves the reparation precision of spool installation or removal, prolongs the service life of valve body.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Accompanying drawing is a structural representation of the present utility model, and as shown in the figure: the device that is exclusively used in the spool mounting or dismounting comprises ball screw 1, screw mandrel sleeve 2, datum plate 3 and application of force gripper shoe 8.Datum plate 3 is fixedly installed on an end of screw mandrel sleeve 2, the axis normal of the datum level of datum plate 3 and screw mandrel sleeve 2, and application of force gripper shoe 8 is fixedly installed on the other end of screw mandrel sleeve 2.Screw mandrel sleeve 2 rotation sets on ball screw 1, an end of ball screw 1 stretch out screw mandrel sleeve 2 and datum plate 3 and with datum plate 3 matched in clearance, it stretches out the end is thimble 4; The other end of ball screw 1 stretch out screw mandrel sleeve 2 and application of force gripper shoe 8 and with application of force gripper shoe 8 matched in clearance, it stretches out the end is drive end 5.
The barrel top of screw mandrel sleeve 2 is provided with oil filler point 6, and described oil filler point 6 is communicated with gap between ball screw 1 and the screw mandrel sleeve 2.Between ball screw 1 and datum plate 3 sealing ring 7 is set, ball screw 1 is sealed and matched by sealing ring 7 and datum plate 3.Can be by injecting lubricating oil in the gap of oil filler point 6 between ball screw 1 and screw mandrel sleeve 2, lubricated ball screw 1 and screw mandrel sleeve 2 during ball screw 1 rotation, reduce the wearing and tearing between ball screw 1 and the screw mandrel sleeve 2, prolong the service life of this device.
When carrying out the spool installation or removal, at first valve body is fixedly mounted on the metalworker's vice, the datum level of datum plate 3 is fitted on the datum level of valve body end face, the spool that the thimble 4 of ball screw 1 is aimed in the valve body, and datum plate 3 is fixed on the metalworker's vice, operating personnel are held on the application of force gripper shoe 8 on the other hand, the another hand uses the drive end 5 of spanner or other tool drives ball screw 1, ball screw 1 is rotated in screw mandrel sleeve 2, thimble 4 on the ball screw 1 vertically descends, spool is vertically ejected or spool vertically is pressed into, spool is along the axial-movement of valve body, improve the concentricity of spool installation or removal, avoid the spool face wearing and tearing and the generation leakage, prolong the service life of valve body.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
