Description

Technical Field

[0001] The utility model belongs to the technical field of detection tooling and relates to a welding part angle error mechanism, which is particularly suitable for accurately identifying unqualified parts with micro angles. Background Art

[0002] The workpiece stabilizer bar includes a shell and a bar; the shell and the bar are welded together. During the stabilizer bar welding process, equipment failure caused the angle between the shell and the bar to be out of tolerance after welding; due to the deformation caused by welding, the welding equipment could not identify the unqualified welded parts. When the welded parts enter the assembly process, the assembly equipment has the function of detecting the length of the parts, but since the length difference between qualified parts and unqualified parts is very small, the equipment cannot identify the unqualified parts, causing quality risks. Summary of the invention

[0003] The utility model discloses a welding part angle error mechanism to solve the problems that the existing welding part angle error recognition cannot be realized, and there is a risk of unqualified parts flowing out.

[0004] The utility model comprises a frame, a driving mechanism, a slide rail, a slide table, a displacement sensor, a positioning tool, a clamping detection tool and a workbench; the displacement sensor is parallel to the slide rail and is installed and connected on the frame; the slide rail is slidably matched and connected with the slide table; the driving mechanism is drivingly connected with the slide table; the driving mechanism drives the slide table, and the slide table can reciprocate along the slide rail in a straight line; the positioning tool is installed and connected on the frame at the rear end of the slide rail; the clamping detection tool is installed and connected on the slide table; the clamping detection tool is provided with a width-limiting detection head; the width of the width-limiting detection head is equal to the width of the width-limiting part of the qualified welding assembly.

[0005] Detection working process:

[0006] The welding assembly is placed on the workbench 6, and the positioning tool 4 limits the welding assembly; the driving mechanism drives the slide 2 and drives the clamping detection tool 5 to clamp the welding assembly; when the welding assembly angle is qualified, the limited width part of the welding assembly can completely enter the limited width detection head 5a of the clamping detection tool 5; when the welding assembly angle is unqualified, the angle difference is tilted, and the limited width part of the welding assembly cannot completely enter the limited width detection head 5a of the clamping detection tool 5; the displacement sensor 3 senses the displacement of the limited width detection head 5a of the clamping detection tool 5; and accurately identifies the workpiece with unqualified welding assembly angle.

[0007] The driving mechanism of the utility model can be a cylinder, a hydraulic cylinder, or a motor.

[0008] The positive effect of the utility model is that by detecting the length of the assembled parts, the lengths of qualified parts and unqualified parts vary greatly during the length detection process, and the parts with out-of-tolerance angles of the welded parts can be accurately and reliably identified, thereby identifying unqualified parts and preventing the unqualified parts from flowing out; the working rhythm of the equipment is synchronized, and the efficiency is high.
