Description

Technical Field

[0001] This utility model belongs to the field of armored vehicle testing technology, and is applicable to the final assembly and adjustment of tracked armored vehicles. Specifically, it relates to a coaxiality measuring device for the transmission mechanism of an armored vehicle. Background Technology

[0002] A tracked armored vehicle recovery and repair vehicle uses a coupling plate to connect its working transmission mechanism and engine bracket. Since the coupling plate between the engine power output end and the working transmission mechanism is rigid, the relative position requirements between the engine output end and the working transmission mechanism are quite strict. The engine's fixed position is already fixed, and the coaxiality requirement between the engine output end and the working transmission mechanism can only be ensured by continuously adjusting the relative position of the working transmission mechanism. However, due to its overall layout and other reasons, it is impossible to use traditional measuring instruments to measure the coaxiality between the engine output end and the working transmission mechanism, which brings certain difficulties to production. There is an urgent need for a utility model device that can measure the coaxiality between the engine output end and the working transmission mechanism. Utility Model Content

[0003] This invention provides a device for measuring the coaxiality of armored vehicle transmission mechanisms, which solves the problem of difficult measurement by traditional measuring instruments.

[0004] This utility model is achieved through the following technical solution:

[0005] A coaxiality measuring device for an armored vehicle transmission mechanism includes a measuring head assembly 1, a measuring body 2, a rotating component 3, adjusting screws 4, screws 5, bolts I6, bolts II7, and nuts 8. The measuring head assembly 1 consists of a measuring plate 9 and a connecting shaft 10. The measuring plate 9 is manufactured from steel plate and has an overall L-shaped shape with a threaded hole on each of its two surfaces. One end of the connecting shaft 10 is connected to the measuring plate 9, and the other end is provided with a flange. During measurement, the flange is connected to the power input end interface of the working transmission mechanism via bolts II7. During measurement, the flange at one end of the measuring body is connected to the engine power output end coupling plate via bolts I6, and the cylindrical surface and end face at the other end respectively contact the two adjusting screws 4 that pass through the threaded holes of the L-shaped measuring plate 9 of the measuring head assembly 1. One end of the rotating component 3 is provided with an external spline, which engages with the internal spline of the power output end of the working transmission device during measurement.

[0006] The connecting shaft 10 is made of round steel, and its end is designed with holes to avoid interference components.

[0007] The end of the rotating component 3 away from the external spline has a threaded hole that mates with the bolt 5, which serves as a wrench.

[0008] Adjusting screw 4 and nut 8 together achieves gap adjustment.

[0009] The axes of the two adjusting screws 4 are in the same plane.

[0010] This invention enables the measurement of the coaxiality between the engine output end and the working transmission mechanism, solving a problem in the production process, ensuring production progress, and improving product assembly quality and service life. Attached Figure Description

[0018] like Figure 1-7 As shown, this utility model is a coaxiality measuring device for the transmission mechanism of an armored vehicle.

[0019] Instructions for use: First, install the overall drawing of the vehicle transmission mechanism coaxiality measuring device. Step one: Assemble the adjusting screw 4 and nut 8 onto the measuring head assembly 1. Then, use bolt II7 to assemble the assembled measuring head assembly 1 onto the power input interface of the working transmission mechanism. Step two: Assemble the measuring body 2 onto the engine power output end coupling plate using bolt I6. Step three: Engage the rotating component 3 with the internal spline of the power output end of the working transmission device. Step four: After adjusting the lateral and longitudinal clearances between the two adjusting screws 4 and the measuring body 2 to a certain value, measure the clearances using a feeler gauge. Record the lateral and longitudinal clearance values ​​between the two adjusting bolts 4 and the measuring body 2; then rotate the measuring head assembly 1 by rotating the rotating component 3, and measure the vertical and horizontal clearance values ​​between it and the measuring body 2 respectively. After numerical calculation, determine whether its coaxiality meets its technical requirements. If it does not meet the requirements, the transmission mechanism can be finely adjusted laterally and longitudinally, and the measurement and calculation can be repeated according to the above measurement method until the measured values ​​meet the technical requirements. After the measurement is qualified, fix the working transmission mechanism; then disassemble and store all armored vehicle transmission mechanism coaxiality measuring devices.
