Abstract

The utility model relates to a drilling jig for processing cover plate hole group of electronic-hydraulic servo valve. The drilling jig comprises a drilling jig body (1), a drill plate (3), a fixed drill sleeve (4) and a special drill sleeve (6), wherein the drilling jig body (1) is rectangular; the drill plate (3) is arranged on the drilling jig body (1); the fixed drill sleeve (4) is arranged on the drill plate (3); the special drill sleeve (6) is arranged on the lateral surface of the drilling jig body (1); and a workpiece is disposed between the drilling jig body (1) and the drill plate (3), and is fixed and compressed by screws (2) and positioning pins (6). The drilling jig has the advantages of ensured processing accuracy, simple structure, low manufacture cost, good operation performance, significantly improved processing efficiency, long service life and is unlikely to be damaged.

Description

Electrohydraulic servo valve cover plate hole group processing drill jig
Technical field
The utility model relates to a kind of processing drill jig of electrohydraulic servo valve cover plate, relates in particular to a kind of electrohydraulic servo valve cover plate hole group processing drill jig.
Background technology
There is following defective in the hole processing that is used for the used electrohydraulic servo valve cover plate part of electrohydraulic control system at present:
Existing processing method: workpiece earlier with the mode positioning and clamping of end face perpendicular to workbench, gets out circumferential hole by behind the digital display device alignment holes position on vertical knee and column milling machine; Again clamping (being parallel to the workbench mode with end face) then, the alignment holes position gets out end-face hole one by one.Whole hole is that workpiece needs the clamping secondary in the process, and centering repeatedly, and working (machining) efficiency is low, and the position error between each hole is also bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electrohydraulic servo valve cover plate hole group processing drill jig, to solve the big defective of each hole Working position error in the prior art.
Technical scheme
The utility model provides a kind of electrohydraulic servo valve cover plate hole group processing drill jig, comprise model drilling body, bushing plate, fixedly drill bushing and special-shaped drill bushing, described model drilling body is a pane, described bushing plate is equipped with at its top, described fixedly drill bushing is installed on the bushing plate, described special-shaped drill bushing is equipped with in the side of model drilling body, and place work piece between model drilling body and the bushing plate is by screw and the fixing also workpiece pressing of alignment pin.
Described special-shaped drill bushing is the fan-shaped drill bushing of chamfered edge.
Described screw is a soket head cap screw.
Described alignment pin is 2, and its two ends are different to be cooperated.
Beneficial effect
A kind of electrohydraulic servo valve cover plate of the present utility model hole group processing drill jig, the workpiece of needs processing is fixed, and accurately located the position in hole, thus guaranteed machining accuracy, simultaneously, the present invention is simple in structure, low cost of manufacture, good operation performance can significantly improve working (machining) efficiency, and not fragile, long service life.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figures 1 to 4, there is shown the group processing of electrohydraulic servo valve cover plate of the present utility model hole and use drill jig, it comprises model drilling body (base plate), bushing plate and special-shaped drill bushing etc., wherein:
Described model drilling body (base plate) 1 is a pane, and it is fan-shaped drill bushing 6 that chamfered edge is equipped with in the side, and end face is equipped with two alignment pin 5, and its two ends are different to be cooperated, and workpiece is by the location of the locating hole on the model drilling body 1;
Fixedly drill bushing 4 is housed on the described bushing plate 3, and whole bushing plate assembly is combined and workpiece pressing with model drilling body 1 by alignment pin 5 and soket head cap screw 2.
As shown in Figure 5, the coverplate parts structure chart that the present invention is processed, circumferential hole 11 and 4 end-face holes 21 are hole to be processed among the figure, because between the hole 21 and certain position degree requirement arranged between hole 21 and the hole 11, if deviation is excessive, the assembly performance of cover plate and electro-hydraulic servo valve body will be had influence on; In addition, if position degree deviation uniformity is bad in a collection of part, also will increase the assembly work amount.
Coverplate parts adds man-hour, and part is by the centre bore of model drilling body 1 location, and the bushing plate assembly by two alignment pin 5 and two soket head cap screws 2 and model drilling body combination of components together and workpiece pressing.Drill jig after the combination can overturn 90 ° on Drilling machines bench, centering and processing are all very convenient.
