Abstract
The invention relates to a jig used to grind flat surface on baffle feedback bar in electro-hydraulic servo valves component, comprising a locating pin (1), a jig body (3) and a tightly fixed bolt (4). The left side and right side of the jig body (3) are vertical and symmetric planes which. The intra-cavity is a hollow cylinder and the baffle feedback bar (2) is arranged in the intra-cavity, the external circle of which is combined with the clearance of the intra-cavity. A screw thread erection hole is arranged on one side of the positioning intra-cavity and a hole is opened at the back of the intracavity, which is a little larger than the positioning circle and can make the baffle feedback bar (2) be put into conveniently and is combined with the small clearance. The tightly fixed bolt (4) is positioned inside the screw thread erection hole of the jig body. The invention has the advantages of increasing the work efficiency of processing the baffle feedback bar in electro-hydraulic servo valves, lowering the requirements toward the technical level of workers, and easily realizing the mass production.
Description
Technical field
The present invention relates to a kind of clipper for feedback lever milling flat face, particularly relate to a kind of electro-hydraulic servo valve part baffle clipper for feedback lever milling flat face.
Background technology
Electrohydraulic servo valve is a kind of high accuracy that is used for electrohydraulic control system, the electro-hydraulic servo control assembly with very high dynamic response, and it can be used for the hydraulic control system of accurate displacement, speed, power and acceleration.Baffle feedback lever is the strength member in the electrohydraulic servo valve, and it is little that it has a volume, and the characteristics that the size and the accuracy of form and position are high are particularly strict to two flat, and hydraulic oil directly is sprayed onto on two flat during valve work, and two flat the depth of parallelisms, fineness require high.Common process mode efficient is low, processing inconvenience, and it is difficult to produce in batches, can't reach the design drawing requirement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of electro-hydraulic servo valve part baffle clipper for feedback lever milling flat face, has solved the low defective of working (machining) efficiency in the prior art.
Technical scheme
The invention provides a kind of electro-hydraulic servo valve part baffle clipper for feedback lever milling flat face, comprise alignment pin, clamp body and holding screw, described clamp body is a vertical plane for the left-right and front-back side, left-right symmetry, inner chamber is a hollow cylinder, baffle feedback lever is placed on its cylindrical and the little matched in clearance of inner chamber in the inner chamber, and its location inner chamber one side is provided with a screw thread placement hole, and its back has hole bigger slightly than setting circle and that baffle feedback lever can be put into smoothly; Described alignment pin is arranged in the placement hole of baffle feedback lever, and with little matched in clearance; Described holding screw is arranged in the clamp body screw thread placement hole.
Described clamp body material is the 45# steel, and fineness is Ra0.8.
Described holding screw (4) material is tin bronze QSn6.5-0.1.
Beneficial effect
Process the electrohydraulic servo valve guard feedback rod with the present invention and made things convenient for parts fixation to be processed later on, two flat processing is carried out on lathe, simultaneously under the prerequisite that guarantees processing request, the uniformity of anchor clamps clamping positioning accuracy is guaranteed, need not to dismantle down part just can measure processing madam's size and form and position tolerance, and the raising working (machining) efficiency, reduced requirement to workman's technical merit, easily realize producing in batches.
Description of drawings
Fig. 1 the present invention later structural representation of the good baffle feedback lever of anchor clamps clamping.
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.
Embodiment 1
As shown in Figure 1, electro-hydraulic servo valve part baffle clipper for feedback lever milling flat face of the present invention comprises alignment pin 1, clamp body 3, holding screw 4 and part baffle feedback rod 2 to be processed.Wherein:
Clamp body 3 materials are the 45# steel, and it is good through the quenching wearability, and fineness reaches Ra0.8, make positioning accuracy height when milling flat face, the left-right and front-back side is a vertical plane, and it is good to have a left-right symmetry degree, the hollow cylinder of inner chamber setting circle and the little matched in clearance of baffle feedback lever cylindrical, its location inner chamber one side is provided with a screwed hole, and its back has hole bigger slightly than setting circle and that baffle feedback lever 2 can be put into smoothly.
Holding screw 4 materials are tin bronze QSn6.5-0.1, are screwed in the clamp body 3, when compressing part to be processed, because of the hardness ratio part is low, therefore can not weigh part wounded, not only compress the effect that the protection piece surface is also played in the location.
The alignment pin material is 45 steel, and handles through blackout, gets rusty preventing, influences accessory size.Pack into during use in the hole in piece part to be processed,, make things convenient for the workman to add and play corrective action man-hour with little matched in clearance, make two flat with the two annular groove depth of parallelisms satisfy the design drawing requirement.
During use, earlier alignment pin is put into the hole of waiting processing parts baffle feedback lever one end, and guaranteed that the alignment pin two ends all expose, convenient beating shown correction;
The baffle feedback lever that installs alignment pin is put into the clamp body inner chamber;
Holding screw is screwed in the clamp body screwed hole, and withstands part baffle feedback rod cylindrical locating surface to be processed gently with the end;
Bring in and proofread and correct the position of baffle feedback lever in clamp body making alignment pin two with dial gauge on the cast iron surface plate;
Tightening holding screw with a word spanner again after proofreading and correct well compresses baffle feedback lever in clamp body;
After the first five step finishes, the good anchor clamps of clamping are inhaled on the magnechuck of grinding machine, a flat face is wherein carried out grinding;
After one flat grinding well, turnover fixture is regrinded another flat.
After this seven roads work step, flat processing of the baffle feedback lever censorship of just can completing, and need not dismantle part during censorship and just can easily test, convenient and practical.
