A kind of valve module prosthetic device and method
Technical field
The present invention relates to a kind of valve module prosthetic device and method, belong to railway vehicle brake service technique field.
Background technology
At present, during the maintenance of brake apparatus valve series products, wearing and tearing and the impression of the rubber part of valve module (a kind of vulcanization member) may impact properties of product.Valve module rubber base exist cracking and distortion must change, this is unrepairable state.If but the part that the valve seat of rubber base contacts is recessed into homogeneous circle or only has impression, not replacing new part has impact to properties of product, replace and waste very much again, also greatly will save parts resource to this kind of situation as reparation can be carried out.
Summary of the invention
For above problem the invention provides a kind of effectively can carry out repairing valve module prosthetic device and method.
A kind of valve module prosthetic device is the invention provides in order to overcome the above problems, it is characterized in that: comprise box-like body, sanding component, sanding component is arranged on box-like body upper surface, sanding component comprises polishing rack, polishing post, track, fixture, track is provided with in the upper surface both sides of polishing rack, fixture connects in orbit, fixture can along rail moving, groove is arranged with at polishing rack inwall, the length of groove is greater than the diameter of polishing post, it is interior and rotatable that polishing post is arranged on groove, and polishing post can move up and down in groove.
Participating in adjustment polishing post moving up and down in groove to reduce manpower, being provided with gas column in the bottom of polishing post, can item automatic lifting polishing post can be made to be fixed in groove again motionless.
Described fixture is selected and can be stretched up and down and lock motionless fixture.
As a modification of the present invention, be provided with dust catcher, between sanding component and dust catcher, be formed with cavity at box-like body inner bottom part, dust catcher effectively can siphon away the disintegrating slag of polishing, and the design of cavity effectively can slow down the impact of air draught on polishing.
A kind of valve module restorative procedure, comprises the following steps:
1st step: recoverable valve module is clipped on fixture, the rubber part of valve module is facing to polishing post;
2nd step: valve module is moved on to polishing post top along track;
3rd step: according to the adjustment polishing position of post in groove, position that need polish, be positioned at groove bottom when polishing post remains static, when needs participate in polishing, polishing post is raised to groove internal upper part;
4th step: valve module is pressed onto on the polishing post of rise by fixture, polishes, and grinding depth is less than or equal to 1mm.
The 3rd described step is specially:
3.1st step: when the rubber part of valve module only needs part to polish, the adjustment polishing position of post in groove, namely have the polishing post of the part correspondence of impression to be positioned at groove internal upper part, the polishing post of intact part correspondence is positioned at groove bottom, does not participate in polishing;
3.2nd when the rubber part of valve module needs entirety to polish, can according to the size adjustment polishing position of post in groove of the rubber part area that need polish, and rubber part does not have chlamydate polishing post to be positioned at groove bottom.
Valve module prosthetic device and the method for the present invention's design can high efficiencyly be repaired.Reduce operative's intensity, reduce a large amount of man-hour, saved replacement cost, energy-efficient and environmental protection and economy.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the structural representation of groove of the present invention.
Detailed description of the invention
As Fig. 1, shown in 2, the invention provides a kind of valve module prosthetic device, comprise box-like body 4, sanding component 1, sanding component 1 is arranged on box-like body 4 upper surface, sanding component 1 comprises polishing rack 1-4, polishing post 1-3, track 1-2, can stretch up and down and lock motionless fixture 1-1, track 1-2 is provided with in the upper surface both sides of polishing rack 1-4, fixture 1-1 is connected on track 1-2, fixture 1-1 can move along track 1-2, groove 1-5 is arranged with at polishing rack 1-4 inwall, the length of groove 1-5 is greater than the diameter of polishing post 1-3, it is interior and rotatable that polishing post 1-3 is arranged on groove 1-5, polishing post 1-3 can move up and down in groove 1-5, gas column 1-6 is provided with in polishing post 1-3 bottom, dust catcher 3 is provided with at box-like body 1 inner bottom part, cavity 2 is formed between sanding component 1 and dust catcher 3.
Above-mentioned valve module prosthetic device is utilized to carry out the process of repairing, if there is the circular impression (not containing 1) of more than 1
First be clipped on fixture 1-1 by recoverable valve module, the rubber part of valve module is facing to polishing post 1-3; Again valve module is moved on to polishing post 1-3 top along track 1-2; Then according to the adjustment polishing position of post 1-3 in groove 1-5, position that need polish;
When the rubber part of valve module only needs part to polish, the adjustment polishing position of post 1-3 in groove 1-5, namely have the polishing post 1-3 of the part correspondence of impression to be positioned at groove 1-5 internal upper part, the polishing post 1-3 of intact part correspondence is positioned at groove 1-5 bottom, does not participate in polishing;
When the rubber part of valve module needs entirety to polish, can according to the size adjustment polishing position of post 1-3 in groove 1-5 of the rubber part area that need polish, rubber part does not have chlamydate polishing post 1-3 to be positioned at groove 1-5 bottom;
Polishing post 1-3 is positioned at groove 1-5 bottom when remaining static, and when needs participate in polishing, polishing post 1-3 is raised to groove 1-5 internal upper part;
Valve module is pressed onto on the polishing post 1-3 of rise by fixture 1-1, and polish, grinding depth is less than or equal to 1mm.
The foregoing is only the preferred embodiments of the present invention, be not restricted to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within right of the present invention.
