Description

A measuring and testing tool for automobile rear protection

technical field

The invention relates to a vehicle body inspection tool, in particular to an automobile rear protection measuring tool for the position of the rear circumference of the vehicle body.

Background technique

With the continuous development of the automobile industry, large-scale automobile production lines continue to appear. In the process of automobile production, due to the different factors such as fixtures used, quality of automobile parts, process equipment, personnel level, etc., the quality of automobile manufacturing is unstable, and the stability at the position of automobile taillights is particularly poor, so the assembly clearance of automobile taillights The profile standard is very strict, which is exactly what the customer strictly requires the manufacturer to control. If the control is not strict, it will seriously lead to car quality accidents and even car recalls, which will directly affect the brand image. The existing technology generally adopts ordinary bumpers as trial fittings, and the cost of a bumper will be between 300-500, depending on the model, or even more expensive, and the rear bumper will be replaced in a few weeks. The bar bracket wears more seriously, and after wearing and tearing, the accuracy of the rear bumper is just quite poor, and the rear bumper that the prior art takes is close to the real thing, and repeated trial fittings cause serious deformation of the rear bumper.

After the clamping device and the detection hole are positioned, a marking pin can be used to mark the position of the mounting buckle hole of the rear bumper to correct the deviation. The tightening rod and the positioning pin are respectively located on both sides of the mounting buckle hole of the rear bumper, and are fixed by screw fit.

As preferably, the positioning pin has a threaded blunt head for positioning, the marking pin head has a scored triangular cone head, the cone angle of the triangular cone head is flat with the pin cylinder surface at the end of the marking pin Alignment, the positioning pins and marking pins corresponding to the same positioning hole or the same detection hole are replaced according to the positioning or marking requirements. When scribing, pull out the positioning pin, insert the scribing pin into the hole, and turn the circle; when positioning, take out the scribing pin, and insert the locating pin into the positioning.

Preferably, the clamping device is a four-link structure with an operating handle.

Preferably, the profile detection block is installed on the cross bar by using a connecting rod.

The invention adopts the integration of a plurality of detection components to detect the structure of the rear protection position of the vehicle body, with low detection cost and high detection efficiency; a combined detachable detection module is adopted, which can be adapted to the detection of various vehicle types.
