Embodiment 1

[0013] Such as figure 1 As shown, the electro-hydraulic servo valve part baffle feedback rod grinding flat surface fixture of the present invention includes a positioning pin 1, a clamp body 3, a set screw 4 and a baffle feedback rod 2 of the part to be processed. in:

[0014] The material of clamp body 3 is 45# steel, which has good wear resistance after quenching, and the smoothness reaches Ra0.8μm, which makes the positioning accuracy high when grinding the flat surface. A hollow cylinder with a small gap between the circle and the outer circle of the baffle feedback rod. There is a threaded hole on one side of the positioning inner cavity, and a hole slightly larger than the positioning circle is opened on the back to allow the baffle feedback rod 2 to be inserted smoothly. .

[0015] The material of the set screw 4 is tin bronze QSn6.5-0.1, which is screwed into the clamp body 3. When pressing the parts to be processed, the hardness is lower than that of the parts, so i...

Abstract

The invention relates to a jig for flattening a baffle feedback rod of an electro-hydraulic servo valve part, comprising a positioning pin (1), a clamp body (3) and a set screw (4), and the clamp body (3) is left, right, front, rear The side is vertical and symmetrical. The inner cavity is a hollow cylinder. The baffle feedback rod (2) is placed in the inner cavity. There is a hole at the back that is slightly larger than the positioning circle and can allow the baffle feedback rod (2) to be placed smoothly; the positioning pin (1) is set in the placement hole of the baffle feedback rod (2), and with a small gap Cooperate; the set screw (4) is set in the threaded hole of the clamp body (3). The invention improves the processing efficiency of the feedback rod of the baffle plate of the electro-hydraulic servo valve, reduces the requirement on the technical level of workers, and facilitates mass production.

Description

technical field [0001] The invention relates to a clamp for flattening surface of a feedback rod, in particular to a clamp for flattening a surface of a feedback rod of an electro-hydraulic servo valve part baffle. Background technique [0002] The electro-hydraulic servo valve is an electro-hydraulic servo control component with high precision and high dynamic response used in the electro-hydraulic control system, which can be used in the hydraulic control system of precise displacement, speed, force and acceleration. The baffle feedback rod is an important part of the electro-hydraulic servo valve. It has the characteristics of small size, high size and shape accuracy, especially strict requirements on the two flat surfaces. When the valve is working, the hydraulic oil is directly sprayed on the two flat surfaces. And the parallelism and smoothness of the two flat surfaces are required to be high. Ordinary processing methods are inefficient, inconvenient to process, diffi...
