Description

Technical Field

[0001] The utility model relates to the technical field of automobile inspection tools, in particular to an automobile plastic parts inspection tool. Background Art

[0002] The plasticization of automobiles is a major development trend in the international automobile manufacturing industry today. The current automotive market demand has shifted to lighter sports utility vehicles, minivans and other light vehicles, which will drive the development of automotive materials towards lighter weight.

[0003] In the production and use of plastic parts, ensuring uniform wall thickness is one of the key factors in the rational design of plastic parts, which is crucial to ensuring the quality of parts and the smooth progress of the processing.

[0004] At present, the wall thickness gauges of automotive plastic parts on the market generally use micrometers to detect the wall thickness of plastic parts. The micrometer is a length measuring instrument that converts general linear displacement (linear motion) into rotational motion of a pointer through gears or levers, and then reads the reading on the dial to obtain the wall thickness of the automotive plastic part. When testing longer plastic parts, the micrometer needs to be frequently driven by gears or levers to move, resulting in low detection efficiency and inability to quickly complete the wall thickness detection of automotive plastic parts. In view of this, an automotive plastic part inspection fixture is now proposed. Utility Model Content

[0034] Furthermore, the measurement and analysis terminal device 14 is fixedly mounted on the right surface of the vertical plate of the gantry 3;

[0035] When the automobile plastic parts inspection fixture is used, the automobile plastic parts to be inspected are placed on the upper surface of the plastic parts inspection workbench 1. At this time, the two hydraulic presses 4 are started. The two hydraulic presses 4 drive the hydraulic rods 5 with the sliding sleeve on the inner surface to move toward the opposite surface through operation. The two hydraulic rods 5 apply opposite thrust to the two auxiliary pulleys 6 fixedly installed at the opposite ends, so that they move toward the opposite surface and contact the surface of the automobile plastic parts. At the same time, the measuring roller 11 contacts the upper surface of the automobile plastic parts. At this time, the electric guide rail 2 is started to drive the gantry 3 with the sliding sleeve on the outer surface to move to the right. At this time, the measuring roller 11 moves to the right on the upper surface of the automobile plastic parts. When the measuring roller 11 passes the high convex part of the automobile plastic parts, the measuring roller 11 The wheel 11 applies an upward thrust to the measuring ruler 8 fixed on the upper surface, causing the measuring ruler 8 to move upward on the inner surface of the fixed block 7. At the same time, the measuring ruler 8 drives the circular ring 9 fixed on the outer surface to move upward. The circular ring 9 applies pressure to the spring 10 fixed on the upper surface, causing it to contract.

The measurement and analysis terminal device 14 analyzes the data to see if it meets the variation range. If it exceeds the wall thickness variation range of the plastic part, an audible alarm will be issued to prompt the staff;

[0036] This automotive plastic parts inspection fixture uses an electric guide rail 2 to drive a gantry 3, which is slidably mounted on the outer surface, to move. The movement of the gantry 3 drives a measuring roller 11 to roll on the outer surface of the automotive plastic part. Through continuous rolling, the wall thickness variation of the automotive plastic part can be tested. The distance between a laser rangefinder 13 and a measuring ruler 8 can be measured. The laser rangefinder 13 transmits this information to a measurement and analysis terminal device 14 for recording the travel distance. The measurement and analysis terminal device 14 analyzes whether the data conforms to the variation range. If the thickness variation range of the plastic part is exceeded, an audible alarm is sounded to alert the staff, making it easier to complete the wall thickness inspection of the automotive plastic part. In addition, the automotive plastic parts inspection fixture uses two hydraulic cylinders 4 to drive two hydraulic rods 5, which are slidably mounted on the inner surface, to move toward opposite surfaces. The two hydraulic rods 5 drive two auxiliary rollers 6, which are fixed on the opposite surfaces, to move toward opposite surfaces to clamp the automotive plastic part. This can keep the automotive plastic part below the auxiliary rollers 6 for easy inspection and prevent it from being offset during inspection, making it more convenient.

[0037] Working principle: When the automobile plastic parts inspection fixture is used, the automobile plastic parts to be inspected are placed on the upper surface of the plastic parts inspection workbench 1. At this time, the two hydraulic presses 4 are started. The two hydraulic presses 4 drive the hydraulic rods 5 with sliding sleeves on the inner surface to move toward the opposite surface through operation. The two hydraulic rods 5 apply opposite thrusts to the two auxiliary pulleys 6 fixed at the opposite ends, causing them to move toward the opposite surfaces and contact the surface of the automobile plastic parts. At the same time, the measuring roller 11 contacts the upper surface of the automobile plastic parts. At this time, the electric guide rail 2 is started to drive the gantry 3 with sliding sleeves on the outer surface to move to the right. At this time, the measuring roller 11 moves to the right on the upper surface of the automobile plastic parts. When the measuring roller 11 passes the high convex part of the automobile plastic parts, The measuring roller 11 applies an upward thrust to the measuring ruler 8 fixed on the upper surface, causing the measuring ruler 8 to move upward on the inner surface of the fixed block 7. At the same time, the measuring ruler 8 drives the circular ring 9 fixed on the outer surface to move upward. The circular ring 9 applies pressure to the spring 10 fixed on the upper surface, causing it to contract. At this time, the distance between the laser rangefinder 13 fixed on the lower surface of the horizontal plate of the L-shaped vertical plate 12 and the measuring ruler 8 is shortened, and the laser rangefinder 13 transmits this part of information to the electrically connected measurement and analysis terminal device 14 for recording this section of travel. The measurement and analysis terminal device 14 analyzes whether the data is in compliance with the variation range. If it exceeds the wall thickness variation range of the plastic part, an audible alarm will be issued to prompt the staff.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
