Description

Technical Field

[0001] This utility model relates to the field of aerospace mechanical processing technology, and in particular to a device for adjusting the altitude of a sensor. Background Technology

[0002] In the field of aerospace mechanical processing and manufacturing, there are numerous assembly components. Due to the high-performance requirements of aerospace products, certain requirements are placed on the overall flow characteristics of hydraulic valve components. Currently, flow characteristics are mainly assessed using a performance testing bench, where displacement sensors drive the movement of parts to open and close flow orifices, thus achieving the purpose of performance testing. However, during use, due to the diverse dimensions of the parts and the need for the displacement sensors to remain at the same height as the part's center, the required displacement sensor clamping devices differ between products. If a new displacement sensor clamping device were to be produced for each product, it would result in resource waste. Therefore, it is necessary to design a universal displacement sensor clamping device through reasonable improvements. Utility Model Content

[0006] The fixing body is a T-shaped structure, with a support structure at the large end and a hollow groove opened along the thickness direction at the small end.

[0007] An internal thread structure is formed at the center of the bottom surface of the hollow groove; the external thread end of the adjusting cylindrical pin mates with the internal thread structure; the adjusting body is a cuboid structure with an inner hole along the height direction on its bottom surface, the inner hole being clearance-fitted with the smooth end of the adjusting cylindrical pin to adjust the adjusting body to a suitable height along the axis of the adjusting cylindrical pin; a fixing body threaded hole is formed on one side wall of the hollow groove; the fixing body threaded hole mates with a fixing screw, the end of the fixing screw extending into the hollow groove pressing against the adjusting body; a mounting body is installed on the top surface of the adjusting body; the mounting body has a circular hole structure along the thickness direction for mounting a sensor.

[0008] Furthermore, the height position of the adjustment body is determined by the height position of the component acted upon by the displacement sensor.

[0009] Furthermore, a slotted structure is formed at the top of the mounting body, and a threaded through hole is formed along the length of the top of the mounting body; the threaded through hole is connected to the slotted structure; the displacement sensor is fixed by applying force through the thread to close the slotted structure.

[0010] Furthermore, one side of the fixing body is provided with four threaded holes for connecting to fixing screws.

[0011] Furthermore, the depth of the through hole in the adjusting body is greater than the length of the adjusting cylindrical pin rod.

[0012] Furthermore, the internal thread depth of the fixing body is greater than the external thread length of the adjusting cylindrical pin.

[0013] This invention solves the problem of adjusting the height of a displacement sensor. The key to its processing lies in changing the height of the adjusting body in the device according to the center height position of the part, and tightening the adjusting body with threads to achieve on-demand adjustment of the displacement sensor height, thereby improving production efficiency and saving production costs.
