Abstract

The present invention provides a high-speed friction wear test auxiliary device which is provided on a lathe, and belongs to the key device used by friction wear test. The device comprises a baseboard (1) which is provided with a horizontal slide way pair (2) at one end of the baseboard (1). An auxiliary body (4) is fixedly connected with a sliding block of the horizontal slide way pair. One end of the auxiliary body (4) is provided with a clamping head (3) which is used for clamping the sample I (12), and the other end is connected with one end of the horizontal spring (5). The other end of the horizontal spring is connected with a loading bolt (7) which is supported by a bolt base (6) installed on the baseboard (1). The device has the advantages of simple structure and low cost, and can transfer load more accurately.

Description

Technical field

[0001] The utility model relates to an auxiliary device for a high-speed friction and wear test configured on a lathe, which belongs to the friction and wear test device. Background technique

[0002] At present, the friction and wear test generally carried out on the existing friction and wear testing machine has the disadvantages of large friction vibration and long material pattern preparation period, and the test conditions are affected by the structure of the equipment, and the friction speed can be realized in a small range, which cannot meet the requirements High-speed friction and wear research needs. For example, the MMW-1A universal friction and wear testing machine has a maximum speed of 2000r / min, but the maximum contact diameter of the sample is 46mm, and the maximum achievable sliding speed is 290m / min, and the friction and vibration will stop once the speed is higher than 1000r / min. Quite obviously, it seriously affects the reliability of the ...
