Rapid eccentric distance detection device

Abstract

The invention discloses a rapid eccentric distance detection device. The device comprises a base, a lower fixing piece, an upper fixing piece, a clamping device, a floating pin and a detection device, wherein the lower fixing piece is used for being clamped with a lower center hole of a crank, the upper fixing piece can move up and down and is used for being clamped with an upper center hole of the crank, the clamping device is used for clamping a rod part of the crank, the floating pin is used for being inserted into pin hole of crank, and the detection device is used for detecting eccentricity of the crank, a detection end of the detection device abuts against the floating pin, the upper fixing piece, the lower fixing piece and the floating pin are vertically arranged on the base, and the detection device and the clamping device are horizontally arranged on the base. By using the rapid eccentric distance detection device provided by the invention, the detection effect of the crank eccentric distance detection device can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of crank detection, and more specifically, relates to a device for quickly detecting eccentricity. Background technique [0002] In the prior art, the crank 04 plays a vital role in the motorcycle crankshaft, and the crank 04 has strict requirements on the eccentricity. If the eccentric distance is out of tolerance, it will affect the compression ratio and affect the work of the engine. The schematic diagram of the commonly used crank detection eccentricity device is as follows: figure 1 As shown, it mainly utilizes a parallel rod 01 to knock into the pin hole of the crank 2, and then uses the deflection meter 02 to detect. The specific implementation method is as follows: [0003] First, use a hand hammer to knock the parallel bar 01 into the pin hole of the crank 04; then, put the center holes at both ends of the crank 04 on the two tops of the deflection meter 02, rotate the crank 04 around the tops, an...

AI Technical Summary

Problems solved by technology

[0004] However, the current crank detection eccentricity device tends to require a lot of standard parts due to the difference in eccentricity and pin hole size, which is likely to cause confusion in management

Moreover, in the process of repeatedly disassembling and installing the parallel bar 01, the balance bar is likely to cause bumps and scratches, and the pin hole of the crank 04 will also cause bumps and scratches, which makes the quality of the crank 04 a potential safety hazard
