According to the grinding device, the design that the replenishing valve is mounted on the panel in an inverted manner and the end part of the valve rod of the replenishing valve is in contact with the eccentric cam mounted on the output shaft of the motor is adopted, the valve rod is driven to simultaneously carry out upward-downward movement and rotational movement, and then, the conical face of the valve seat and the conical face of the valve rod automatically grind each other, so that a better grinding effect is achieved, the accuracy of the shape and position of the conical valve port is ensured, the damage to the conical valve port is avoided, and a lot of human and material resources are saved.
Description
Technical field
The present invention relates to a kind of milling tool, particularly a kind of lapping device that is applicable to prefill valve valve port.
Background technology
Prefill valve is a kind of hydraulic oil replenishment valve for high-volume hydraulic system, and in the time that valve port is opened, hydraulic oil flows out; In the time that valve port is closed, hydraulic oil stops flowing out.Valve port is mainly the taper valve port that the valve seat conical surface and the valve rod conical surface form, and in order to ensure the sealing effectiveness of valve port, taper valve port must be through grinding to reach necessary precision.At present, valve port mainly grinds with the instrument of manual rotation structure, inefficiency, and also milling tool grinds valve seat and valve rod respectively, is difficult to guarantee the precision of taper valve port, do not reach desirable sealing effectiveness.
Utility model content
For the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of lapping device that is specifically designed to prefill valve valve port.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of lapping device for prefill valve valve port, described prefill valve comprises valve seat and valve rod, the tapered valve port of valve rod cone-shaped of the valve seat conical surface of described valve seat and valve rod, described lapping device comprises base plate, at least two support bars are installed on described base plate, adjustable panel is installed on described support bar, on described panel, having can filling liquid valve valve rod and the hole passed of prefill valve guide pin bushing, mounted motor on described base plate, the output shaft of described motor connects eccentric cam, when described eccentric cam turns to peak, can contact with valve rod end, contact point is near valve rod outer end diameter part.
Preferably, on described panel, there is calibration circle.
Preferably, the panel on described support bar regulates height with nut.
This lapping device adopts to be inverted prefill valve to be arranged on and on plate, the design that prefill valve valve rod end contacts with the eccentric cam being arranged on motor output shaft, band ovable valve stem moves up and down simultaneously and rotatablely moves, the valve seat conical surface and the valve rod conical surface are ground automatically mutually, thereby reach better grinding effect, guarantee the accuracy of form and position of taper valve port, avoid damaging taper valve port, save a large amount of manpower and materials.
Accompanying drawing explanation

Fig. 2 is structural representation of the present utility model;
1, valve seat; 2, valve rod; 3, the valve seat conical surface; 4, the valve rod conical surface; 5, taper valve port; 6, base plate; 7, support bar; 8, panel; 9, motor; 10, output shaft; 11, eccentric cam; 12, oil-in; 13, valve port is opened control piston; 14, guide pin bushing; 15, spring, 16, hole.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, prefill valve comprises valve seat 1 and valve rod 2, and the valve seat conical surface 3 of valve seat 1 and the valve rod conical surface 4 of valve rod 2 form taper valve port 5, and the surface of taper valve port 5 is the abradant surface that needs grinding.
The operation principle of prefill valve: oil-in 12 oil-feeds, promote valve port unlatching piston 13 and move downward, back down valve rod 2, from A chamber, the oily passage of mistake and the taper valve port 5 through guide pin bushing 14 circumference flows to B chamber to hydraulic oil.When oil-in 12 deoils, spring 15 overhead-valve bar 2 returns, block flowing of A, B chamber hydraulic oil.Prefill valve taper valve port 5 areas are large, when taper valve port 5 seals, can not have hydraulic oil seepage.Because taper valve port 5 is large, seal request is high, and taper valve port 5 must just can make prefill valve reach result of use through grinding.
As shown in Figure 2, a kind of lapping device for prefill valve valve port, this lapping device comprises base plate 6, and 2 or 3 support bars 7 are installed on base plate 6, on support bar 7, with nut installation panel 8, the height of panel 8 can regulate.On panel 8, have the hole 16 that can supply valve rod 2 and guide pin bushing 14 to pass, suitable motor 9 is installed on base plate 6, the output shaft 10 of motor 9 connects eccentric cam 11, when eccentric cam 11 turns to peak, contacts with valve rod 2 ends, and contact point is near valve rod 2 end face external diameters.Eccentric cam 11 actuate valve stem 2 outer end diameter parts, make valve rod 2 move up and down and rotatablely move.
The course of work of this lapping device is: prefill valve is inverted and is arranged on panel, taper valve port 5 is coated to abrasive pastes, starter motor 9, motor 9 drives eccentric cam 11 to rotate with the frequency of 30-40 rev/min, eccentric cam 11 acts on valve rod 2 outer end diameter parts, promotes valve rod 2 and moves up and down and gap circular motion.In the time that eccentric cam 11 moves to descending circular arc, valve rod 2 moves downward by deadweight, and the valve rod conical surface 4 produces and contacts with the valve seat conical surface 3, and the valve seat conical surface 3 and the valve rod conical surface 4 are ground.In order to facilitate the use of this lapping device, can carry out counterweight to valve rod 2.
Find fast tram for the ease of prefill valve installing while grinding, can be at panel 8 calibration circle of getting on the bus out.With nut adjusting panel 8 height, can make this lapping device be applicable to various prefill valves.
This utility model is utilized the design of eccentric cam 11 and stress point, when being moved up and down, prefill valve valve rod 2 produces gap circular motion, the valve seat conical surface 3 and the valve rod conical surface 4 are ground automatically mutually, thereby reach better grinding effect, guarantee the accuracy of form and position of taper valve port 5, avoid damaging taper valve port 5.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described, 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 modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
