Description
Technical field
The utility model relates to machinery fields, and in particular to the control valve fine grinding conical surface follows set.
Background technique
Control valve is made of two main sub-assemblies: valve body sub-assembly and executing agency's sub-assembly (or system of executing agency
System), it is divided into four big series: single seat series of control valves, two-seater series of control valves, sleeve series of control valves and the control of self-operated type series
Valve.Control valve is the actuator in robot control system(RCS), its application quality directly reacts on the regulation quality of system.Control valve valve
The grinding accuracy of body and the conical surface that spool cooperates is more demanding, at present when being ground the conical surface, using the periphery of workpiece as
Benchmark first has to external disc finishing, the outer circle is recycled to refine the conical surface as benchmark, and the precision of the periphery itself is wanted
It asks not high, does not need to be machined to this precision, it is only for guarantee the precision of the conical surface and periphery is machined to certain essence
Degree, and each workpiece is not always the case, and influences production efficiency.
Summary of the invention
The utility model provides the control valve fine grinding conical surface and follows set, solves the prior art and refines cone using outer circle as benchmark
Face needs the problem of periphery of each workpiece is machined to certain precision and influences production efficiency.
The utility model is achieved through the following technical solutions:
The control valve fine grinding conical surface follows set, including bottom plate, supporting block, axial baffle and follows set, and the bottom plate is fixed
It is connected on grinding machine board, the supporting block is equipped with V-shaped groove, described that set is followed to be pressed in the V-shaped groove by rotation pinch roller, V-arrangement
Seiko is refined in the side of slot, and the fine grinding cylinder processing for following set to contact with V-shaped groove is followed and put on equipped with coaxial through-hole,
The through-hole is stepped hole, and the aperture of the part contacted with workpiece is less than the aperture of other parts, follows the axis and axial gear of set
Plate is vertical, and follows and cover one end far from axial baffle equipped with clamping device.Wherein, follow set outer circle circularity be
0.0005mm, roughness Ra0.2, straightness 0.001mm, external conicity 0.001mm, follow set outer diameter tolerance be
0.01mm。
It is the part fine grinding for following set to contact with workpiece that the utility model, which is further improved scheme,.
The utility model is further improved scheme, the clamping device include be set to follow the upper gripping block of set and with
Follow that external threading connects and cap, gripping block with and the contact surface of cap be inclined-plane, tighten and when cap, gripping block is by Workpiece clamping.
The utility model is further improved scheme, and described one end for following the close axial baffle of set is located at through-hole end and sets
There is chamfering, card between set and axial baffle is followed to have steel ball.Axial baffle to follow set axially position, and steel ball is kept off with axial
Plate is point contact, and rotation friction is small.
The utility model compared with prior art, has the advantages that
The utility model structure is simple, after using workpiece roughing benchmark outer circle, workpiece is placed on and is followed in set, by pressing from both sides
Tight device clamps, so that workpiece and following and not occurring mobile between set or rotate, steel ball is placed on and is followed at set tail portion inner hole, is done
Axially position is used, and finally set and locking ball will be followed to be placed in the V-shaped groove in supporting block together, is put down rotation pinch roller, make
Set is followed to rotate, equipment feeding, abrasive grinding wheel refines the product conical surface, utilizes the cone for following set excircle orientation requirement on machining accuracy high
Face, reach one finished outer circle follow set that can process multiple products, reduce converted products Excircle machining precision, drop
Low production cost, can rapid clamping workpiece, converted products is high-efficient, quality stablize.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view for following set.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figures 1 and 2, the control valve fine grinding conical surface follows set, including bottom plate 1, supporting block 2, axial baffle 4 and with
With set 6, the bottom plate 1 is fixedly connected on grinding machine board, and the supporting block 2 is equipped with V-shaped groove 3, described to follow set 6 by rotating
Pinch roller is pressed in the V-shaped groove 3, and Seiko is refined in the side of V-shaped groove 3, the fine grinding cylinder processing for following set 6 to contact with V-shaped groove 3, with
It is equipped with coaxial through-hole with set 6, which is stepped hole, and the aperture of the part contacted with workpiece 9 is less than other parts
Aperture, follow the axis of set 6 vertical with axial baffle 4, and follow and cover 6 one end far from axial baffle 4 equipped with clamping device,
It is described to follow the 6 part fine grindings that contacts with workpiece 9 of set, the clamping device include be set to the gripping block 8 that follows cover on 6 with
And with follow 6 is threadedly coupled and caps 7 of set, gripping block 8 with and the contact surface of cap 7 be inclined-plane, tighten and when cap 7, gripping block 8 by
Workpiece 9 clamps, described that set 6 is followed to be located at through-hole end equipped with chamfering close to one end of axial baffle 4, and set 6 is followed to keep off with axial
Card has steel ball 5 between plate 4.
