Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile workpiece manufacturing, in particular to a checking tool used for screw welding detection. Background Art
[0002] The upper front assembly of a car is an important part of the car body. It usually includes the front panel, front windshield, front windshield wiper, windshield washer assembly, front cover, engine hood and front bumper. These parts are assembled together by welding, riveting or screw connection to form the upper front assembly of the car. When the factory manufactures the upper front assembly of the car, a manipulator is used to weld several screws on the upper front assembly of the car. Welding screws are usually used to firmly connect the front panel, front windshield, front bumper and other parts together to improve the stability of the entire assembly. During the driving process of the vehicle, various external forces will cause vibration and impact on the body. Welding screws can effectively reduce the impact of these external forces on the assembly and ensure the stability and safety of the body. In order to ensure the accuracy of the screw welding position, the screw welding position needs to be strictly inspected and measured after the screw welding is completed. If deviations or defects are found in the welding position, remedial measures such as re-welding and trimming need to be taken in time to ensure the quality and safety of the entire body.
[0003] The existing detection method is to manually use a gap gauge to directly measure the position of the screw welding. Since the end of the gap gauge is sharp, it is particularly easy to poke workers or scratch parts when not in use, causing unnecessary losses. Utility Model Content
[0004] The utility model aims to provide a gauge for screw welding detection, so as to solve the problem that the existing gap gauge is particularly easy to poke workers or scratch parts when not in use.
[0005] In order to solve the above problems, the technical solutions provided are as follows:
[0006] A gauge for screw welding detection comprises a gap gauge, wherein the gap gauge is divided into a head section and a tail section, wherein the tail section has a pointed end, a cavity is arranged in the middle of the head section, slide rails are arranged on both sides of the inner wall of the cavity, and protruding sliders are arranged on both sides of the tail section, wherein the sliders are slidably connected to the slide rails so that the tail section can extend into or out of the cavity of the head section.
[0007] The basic principle of the above technical solution is that when the gap ruler is not in use, the tail section of the gap ruler is extended into the cavity of the first section of the gap ruler for storage; when the gap ruler is needed to measure the position of the screw welding, the tail section of the gap ruler is extended from the cavity of the first section of the gap ruler, and the first section and the tail section are connected into one section to form a complete gap ruler.
[0008] The beneficial effect of the above technical solution is that compared with the existing gap gauge, this solution divides the gap gauge into two sections. When the gap gauge is not in use, the tail section with a pointed head is stored in the cavity of the first section, which will not injure workers or scratch parts, avoiding unnecessary losses.
[0009] Furthermore, two through holes are symmetrically provided on both sides of the end of the first section close to the cavity opening, and mounting grooves are symmetrically provided on both sides of the end of the tail section connected to the first section. A spring is transversely fixedly connected in the mounting groove, and a limit block is fixedly connected to the end of the spring.
[0010] When the tail section of the gap ruler is completely extended out of the cavity of the first section, the mounting groove is opposite to the through hole, and the spring in the mounting groove pushes the limit block out of the through hole, so that the tail section can be stably connected to the first section when extending out of the cavity, and does not affect the measurement and use of the gap ruler. When the gap ruler is used, the limit block is pressed into the mounting groove by hand, and the tail section of the gap ruler can be slid and stored in the cavity of the first section.
[0011] Furthermore, the inspection fixture also includes a flexibly rotatable positioning arm, and an L-shaped block is detachably connected to one side of the positioning arm.
[0012] Place the positioning arm to the welding position of the screw so that the screw is at the arm bend of the L-shaped block. Use a gap gauge to measure whether the width of the screw from both sides of the L-shaped block is consistent. If not, it proves that the welding position of the screw is not accurate and needs to be readjusted.
[0013] Furthermore, a gap ruler is suspended on the positioning arm via a spring rope.
[0014] The gap ruler is suspended on the positioning arm by a spring rope, so it will not be lost and is easy to find when in use.
[0015] Furthermore, a cover plate which can be embedded in the cavity opening is hinged at the lower end of the cavity opening of the first section.
[0016] When the tail section of the gap ruler is stored in the cavity of the first section, a cover plate is used to close the opening of the tail section cavity to prevent the tail section from falling out of the cavity.
[0017] Furthermore, a pull rod is provided on the cover plate.
[0018] The cover can be easily pulled up and rotated by the pull rod. BRIEF DESCRIPTION OF THE DRAWINGS
