X-Y axial fine turning device for test bench of engine

Abstract

The invention discloses an X-Y axial fine turning device for a test bench of an engine. The device is characterized by consisting of an X axial fine turning device and a Y axial fine turning device which are vertically connected with each other, wherein the X axial fine turning device comprises an X axial sliding block, an X axial guide rail, an X axial nut supporting plate, an X axial adjusting screw rod and an X axial adjusting handle; a plurality of locking pins and fixing screw rods are arranged on the X axial sliding block; the X axial sliding block is arranged in the X axial guide rail; the X axial nut supporting plate is in bolt connection with the front end surface of the X axial guide rail; and the X axial adjusting handle is fixedly connected with the X axial sliding block through the X axial adjusting screw rod and a threaded through hole of the X axial supporting plate. The device has a reasonable design and high accuracy and is convenient to operate; adjusting and centering time is saved; and when a lifting Y screw rod or a translation X screw rod are adjusted and nuts are locked, the accuracy of the device can reach more than 0.004mm, so that the original adjustment accuracy is greatly improved. By the device, the engine can be smoothly tested on the test bench.

Description

technical field [0001] The invention relates to an engine position precise positioning device in an engine test stand, in particular to an X-Y axial fine-tuning device for the engine test stand. Background technique [0002] Usually, when the fuel engine is tested on the test bench, multiple spiral lifting devices are used to support the engine, so that the engine center height can be adjusted within a certain range, so that the engine center height can meet the set requirements; while adjusting the engine center height The work is very complicated and cumbersome. It usually takes about one day to calibrate the size of the X-Y axis, and the accuracy cannot be accurately controlled. Usually, the moving support body is tapped with a cork hammer or rubber hammer to gradually reach the required size. [0003] Inaccurate engine positioning not only easily leads to inaccurate data measurement, inaccurate control of engine speed and torque, but also more likely to cause damage and ...

AI Technical Summary

Problems solved by technology

[0004] The screw lifting device used in the engine test bench in the prior art (patent number: 200920083229.0) includes a base, a lifting screw, and a lifting nut. The lifting screw is arranged in the base and is threadedly connected with the base. Connection, the knurled surface of the polished rod at the lower part of the lifting screw is provided with a tile-holding device, and a plurality of threaded through holes are provided on the base, and fastening bolts are provided on the threaded through-holes. The polished rod is in precise contact, and the fastening bolt can be pressed tightly with the tile device. The utility model has simple structure, reasonable design and convenient operation, but the device can only be adjusted in the Y-axis
