Locking tool for tire dynamic balance test and tire dynamic balance test system

Abstract

The invention relates to the technical field of automobile tire dynamic balance detection, and provides a locking tool for tire dynamic balance detection and a tire dynamic balance detection system. The locking tool includes a telescopic mechanism and a clamping device; the telescopic mechanism includes a body part and a telescopic part that can be sleeved on the shaft body, and the telescopic part is telescopically matched with the body part; the clamping device is arranged on the body part for clamping the shaft Body, so that the telescopic part and the hub form a conflicting fit. The tire dynamic balance detection system includes a tire dynamic balance testing machine and the above-mentioned locking tools. The combined use of the telescopic mechanism and the clamping device not only ensures that the clamping device can clamp the shaft effectively and quickly, is stable and reliable, does not cause the problem of "slipping wire", but also speeds up the speed of fixing the wheel, and the telescopic mechanism directly Clamp the wheel, the fixing effect is good, and the whole operation saves a lot of time and cost compared with manual tightening.

Description

Locking tool for tire dynamic balance test and tire dynamic balance test system technical field The present invention relates to automobile tire dynamic balance detection technical field, be specifically related to a kind of tire dynamic balance detection with locking Tool and tire dynamic balance detection system. Background technique In the process that the dynamic balance detection is carried out to the automobile wheel, the wheel needs to be sleeved on the axle body of the balance testing machine, Then use the locking tool to cooperate with the thrust plate on the axle body to clamp and fix the hub of the wheel. Existing locking tool is a nut with a wrench, and the shaft body of the balance testing machine has external threads, and the locking tool The inner thread of the tool is matched with the outer thread on the shaft body. By rotating the locking tool, the wheel hub is squeezed to the thrust plate, so as to lock the wheel fixed. In order to avoid the ext...

Problems solved by technology

[0004] In order to avoid damage to the external thread on the shaft body of the balance testing machine, the internal thread of the locking tool is generally made of softer material such as plastic than the metal shaft body, so that during repeated use, the internal thread of the locking tool and the metal shaft body When the external thread is connected and occluded, it is very easy to wear and tear, that is, the phenomenon of "slipping the wire" occurs, the service life is low, and it is easy to cause the tire to not be locked in place, which affects the authenticity of the dynamic balance detection data

In addition, the manual tightening method is cumbersome and inefficient, which seriously affects the production efficiency.
