Abstract
The invention relates to a valve housing inner hole measurement tool of an electrohydraulic servo valve, including a pedestal (5), a bolt (3) for a vertical base (2) and a positioning pin (4) are fixed on the pedestal (5), the vertical base (2) is mounted with a measurement rod (6) via a screw (1). The invention evens forces that are applied to every parts of the valve housing by fixing the measurement rod horizontally by the vertical base, which is more advantageous for axial rotation and radial movement of the valve housing and which better facilitates reading buoy of a pneumatic micrometer for an operator so as to make a good record of data; in addition, the invention lowers costs on processing and measurement, raises working efficiency and reduces labor intensity of workers.
Description
Technical field
The invention belongs to the valve pocket hole measuring field of electrohydraulic servo valve, particularly relate to a kind of valve pocket hole measuring frock of electrohydraulic servo valve.
Background technology
There is following defective in the valve pocket hole measuring that is used for the used electrohydraulic servo valve of electrohydraulic control system at present:
Existing method of testing: be size, linearity, the circularity of directly manually testing the valve pocket endoporus by prod, thereby can cause error on to a great extent the size, form and position tolerance is inaccurate, and particularly Measuring Time prolongs greatly, has increased operator's working strength.
Summary of the invention
Technical matters to be solved by this invention provides a kind of valve pocket hole measuring frock of electrohydraulic servo valve, to solve in the prior art with the inaccurate defective of the direct manual test valve pocket of prod endoporus.
A kind of valve pocket hole measuring frock of electrohydraulic servo valve comprises base (5), and stand (2) is fixed on the base (5) with bolt (3) and location pin (4), and described stand (2) is gone up and installed and measured rod (6) by screw (1).
Beneficial effect
The present invention gets up the prod horizontal fixed by stand, so just can make valve pocket stressed evenly everywhere, more helps the axial rotation of valve pocket and moves radially, and make the operator see the buoy of air-gauge more easily, carries out the record of data; In addition, make that also the cost in processing, measurement is minimized, work efficiency rises to some extent, and working strength of workers also reduces thereupon.
Description of drawings
Fig. 1 is the front view of structural representation of the present invention;
Fig. 2 is the left view of structural representation of the present invention.
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.
A kind of valve pocket hole measuring frock of electrohydraulic servo valve, comprise base 5, there is the through hole of one group of counterbore and one group of φ 5 upper end of base 5, and counterbore is to place bolt 3 fastening stands 2, the through hole of φ 5 is that placement positioning pin 4 is located stand 2, installs and measures rod 6 with screw 1 on the described stand 2.
Among Fig. 2, after fixing prod 6, adjust the buoy of air-gauge, and then valve pocket is enclosed within on the prod 6 that fixes, determine the position of buoy, can accurately calculate the interior hole dimension of valve pocket then with the standard block gauge of two different sizes.
Claims (1)
1. the valve pocket hole measuring frock of an electrohydraulic servo valve is characterized in that: comprise base (5), stand (2) is fixed on the base (5) with bolt (3) and location pin (4), and described stand (2) is gone up and installed and measured rod (6) by screw (1).
