Abstract
The invention discloses a drill jig used for circumferential and axial hole combination processing of a cover plate of an electrohydraulic servo valve, which comprises a drill jig body (1), a drill jig plate (3), a fixed drill bush (4) and a special drill bush (6); wherein, the drill jig body (1) is rectangular and the drill jig plate (3) is arranged at the top; the fixed drill bush (4) is arranged on the drill jig plate (3); the special drill bush (6) is arranged at lateral face of the drill jig body (1); a plurality of workpieces arranged between the drill jig body (1) and the drill jig plate (3) are fixed and pressed with a screw (2) and a locating pin (6). The invention has the advantages of simple structure, low manufacturing cost, good manipulability, long service life, assured processing precision, improved processing efficiency and uneasy damage.
Description
Technical field
The present invention relates to a kind of processing drill jig of electrohydraulic servo valve cover plate, relate in particular to a kind of circumferential and axial hole combination processing drill jig of electrohydraulic servo valve cover plate.
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 by this invention provides a kind of circumferential and axial hole combination processing drill jig that is used for electrohydraulic servo valve cover plate, to solve the big defective of each hole Working position error in the prior art.
Technical scheme
The invention provides a kind of circumferential and axial hole combination processing drill jig of electrohydraulic servo valve cover plate, 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
The circumferential and axial hole combination processing drill jig of a kind of electrohydraulic servo valve cover plate of the present invention, 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 present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.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 present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figures 1 to 4, there is shown the combination processing of electrohydraulic servo valve cover plate circumferential and axial of the present invention 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.
