Hook arm frame detection device and method

Abstract

The invention discloses a hook arm frame detection device and method. The detection device comprises a clamping plate, a detection block, a guide sleeve and a bearing, wherein a notch A, a notch B anda notch C are formed in the left side of the clamping plate; the notch A is connected with the notch B and the notch C in sequence; a through hole is formed in the clamping plate; the detection blockis fixed on the notch B; the guide sleeve is matched with the through hole and is fixed on the clamping plate; and the bearing is matched with an inner hole of the guide sleeve. According to the detection device and method, whether a round steel welding position of a hook arm frame is accurate or not can be detected before the hook arm frame is welded to a compartment, so that unqualified products are prevented from flowing to the next procedure, and meanwhile, the detection operation is simple; a detection tool is relatively light, so that the operation of workers is time-saving and labor-saving; the detection efficiency is improved; and the situation that round steel cannot be hooked or can be hooked but cannot be firmly fixed due to inaccurate matching between the pulling arms of a vehicle chassis and the round steel of the hook arm frame is effectively avoided.

Description

technical field [0001] The invention belongs to the field of detection fixtures, and relates to a hook arm frame detection device and a detection method. Background technique [0002] A hook arm frame is welded at the front end of the draw arm carriage, and the hook arm frame is formed by welding a round steel between the two side plates and the two side plates. The chassis of the vehicle is equipped with a hook arm, and the head of the hook arm is provided with a crotch. Every time the car is placed on the ground or lifted from the ground to the chassis, it is completed by hooking the hook arm frame on the front end of the car through the hook on the head of the hook arm on the chassis of the vehicle, and the car hook The round steel of the jib is exactly the part that cooperates with the crotch of the hook arm. There is a pin hole on the hook arm frame, because the pin shaft hole is to be assembled with the pin on the carriage, so the welding position of the hook arm fra...

Problems solved by technology

In the detection process, there are many procedures, and the operation of the workers is troublesome. At the same time, when the workers move the hook arm frame to the platform or turn the hook arm frame 90 degrees, because the material of the hook arm frame is iron plate and round steel, the overall The weight is heavy, the workers are time-consuming and laborious in the detection process, and the detection efficiency is low
