Abstract
The utility model belongs to the technical field of overhauling and replacement of electric locomotive parts, and mainly relates to a press mounting device for the rubber moulding plate of a pressure switch. The press mounting device mainly comprises a pressing seat (4) and a gland, wherein fastening bolt holes (1) are symmetrically formed at the four corners of the pressing seat (4), a valve core overhaul cavity (2) matched with a valve core in shape is arranged inside the pressing seat (4), the valve core overhaul cavity (2) is a stepped round cavity, and an annular groove (3) for the placement of the rubber moulding plate is formed at the periphery of the valve core overhaul cavity (2); fastening bolt holes corresponding to the fastening bolt holes (1) on the pressing seat (4) are formed on the gland; and a clamp spring hole used for dismounting the rubber moulding plate is formed in the center of the gland. The press mounting device has the characteristics of simple structure, quickness and convenience, the valve core with the rubber moulding plate is placed inside the body of the pressing seat, the pressing seat cover is driven to exert pressure downwards through the bolts at the four corners of the pressing seat, then a pair of clamp spring pliers is used for demounting or mounting a clamp spring in place easily, and during the entire process, the valve core is prevented from damages, so that the pressing mounting quality of the rubber moulding plate is ensured.
Description
Technical field
The utility model belongs to maintenance, the replacing technical field of electric locomotive part, relates generally to a kind of pressure switch rubber form press-loading apparatus.
Background technology
At present, the maintenance of electric locomotive pressure switch mainly be on bench vice, dismantle, fitting operation, the wherein dismounting of rubber diaphragm on the inner spool, be installed on the work bench vice and clamp, utilize instrument dismounting jump ring then, if the tension of work bench vice folder is hindered spool easily, the too pine of folder, operation is rocked back and forth, can't normal running.Especially when the rubber diaphragm that more renews, because new rubber diaphragm is thicker, locking jump ring can't press-fit smoothly, and the build-up of pressure switch can't overhaul.If utilize the screwdriver punching press by force, can cause the distortion of spool face pressing plate, rubber diaphragm press-fits lack of standardization, and repair quality is defective.
Summary of the invention
The purpose of this utility model is to propose a kind of pressure switch rubber form press-loading apparatus, can guarantee the repair quality of spool in the quick replacing that realizes the rubber form on the spool under the prerequisite of not hindering spool, has improved rubber form and has changed efficient.
The utility model is finished the technical scheme that its invention task taked:
A kind of pressure switch rubber form press-loading apparatus, mainly constitute by wedge and gland, be symmetrically arranged with the fastening screw keyhole on four jiaos of described wedge body, be provided with the spool maintenance chamber of joining with spool shape kissing in the inside of wedge body, spool maintenance chamber is stair-stepping circular chamber, and outer periphery is equipped with the cannelure of placing rubber form in valve maintenance chamber; Described gland is provided with the fastening screw keyhole corresponding with the fastening screw keyhole of wedge, has the clamp spring hole that is used to dismantle rubber form in the gland in the heart.
The pressure switch rubber form press-loading apparatus that the utility model proposes, have simple in structure, characteristics quickly and easily, the spool that will have rubber form is put into the wedge body, bolt by four jiaos of wedges, driving gland exerts pressure downwards, again with Circlip tongs easily with jump ring dismounting or be in place, spool is not damaged in the whole process, makes the assurance that press-fits quality of rubber form.
Description of drawings
Fig. 1 is a wedge front view of the present utility model.
Fig. 2 is a wedge vertical view of the present utility model.
Fig. 3 is a gland front view of the present utility model.
Fig. 4 is a gland vertical view of the present utility model.
Among the figure: 1, fastening screw keyhole, 2, spool maintenance chamber, 3, cannelure, 4, wedge.
The specific embodiment
With embodiment the utility model is further specified in conjunction with the accompanying drawings:
Shown in Fig. 1,3, a kind of pressure switch rubber form press-loading apparatus, mainly constitute by wedge 4 and gland 5, be symmetrically arranged with fastening screw keyhole 1 on four jiaos of described wedge 4, be provided with the spool maintenance chamber 2 of joining with spool shape kissing in the inside of wedge 4, spool maintenance chamber 2 is stair-stepping circular chamber, and outer periphery is equipped with the cannelure 3 of placing rubber form in spool maintenance chamber; Described gland is provided with the fastening screw keyhole corresponding with the fastening screw keyhole 1 of wedge 4, has the clamp spring hole that is used to dismantle rubber form in the gland in the heart.
Use of the present utility model is as follows: at first, the pressure switch of needs maintenance is disintegrated, take out the spool in the pressure switch, have rubber form on the spool, rubber form is fastened on the poppet shaft by jump ring, secondly jump ring is positioned at the jump ring groove on the rubber form spool,, the gland of press-loading apparatus is taken off, put into spool maintenance chamber 3 at the spool that will have rubber form, at last, gland is pressed on the wedge 4, with the fastening four jiaos of bolts that tighten in the bolt hole of spanner, spool is applied axial pressure, impel jump ring to be in not to be subjected to the effect of axial force, take off jump ring, unclamp clamp nut with bow compass, take off gland, change the rubber form on the spool, the new rubber pressing plate after the repetition aforesaid operations will be changed is fastening with jump ring, promptly finishes the replacing of a rubber form.
Claims (1)
