AI Technical Summary
In the existing technology, the detection efficiency and accuracy of zipper reinforcement plates are low, which makes it impossible to effectively control product quality.
Design a zipper reinforcement plate inspection tool including a base, protrusions, positioning pins, go/no-go gauges, and flush gauges. The positioning pins and go/no-go gauges are used to inspect the positioning holes and circumferential surface clearances, while the flush gauges are used to inspect the flatness of the cut edges, thus achieving a standardized inspection process.
This improves the accuracy and efficiency of zipper reinforcement plate testing, simplifies the testing process, reduces human error, and ensures consistent product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a zipper reinforcement plate inspection tool. Background Technology
[0002] A zipper is an irregularly shaped structural component with multiple facets. The zipper reinforcement plate must fit well with it to effectively reinforce stress. The zipper reinforcement plate has two mounting holes, and four local surfaces near the mounting holes are flush. Therefore, when inspecting the zipper reinforcement plate, its corresponding four surfaces are usually used as reference surfaces, and the two mounting holes are used as positioning holes. The two positioning holes and four positioning surfaces on the zipper reinforcement plate must correspond to the zipper; otherwise, it will affect its use. Simply relying on experience to directly inspect the zipper reinforcement plate is time-consuming and laborious, and cannot achieve accurate judgment, resulting in poor product quality control. Summary of the Invention
[0003] The purpose of this invention is to provide a zipper reinforcement plate inspection tool with hole position detection, plane detection and cut flatness detection, which aims to solve the problems of low detection efficiency and low accuracy when inspecting a zipper reinforcement plate.
[0004] The technical solution adopted by this utility model is: a zipper reinforcement plate inspection tool, including a base, a protrusion fixed on the base as the main body, a groove in the middle of the main body, the inner contour of the groove fitting the outer contour of the zipper standard part, two pin holes and four positioning blocks at the bottom of the groove, two positioning pins inserted in the pin holes, a double-ended go / no-go gauge with one end φ2.5mm and the other end φ3.5mm, and a flush gauge.
[0005] A further technical solution of this utility model is: a go / no-go gauge seat is fixed on the base, the go / no-go gauge seat includes a silicone groove in the middle, and four limiting pins at both ends.
[0006] A further technical solution of this utility model is: a flush gauge seat is fixed on the base, and the flush gauge seat includes a silicone slot.
[0007] The beneficial effects of this utility model are as follows: by adopting the above technical solution, the two positioning pins are removed, the zipper reinforcement plate is placed in the main body, the zipper reinforcement plate is placed on the four positioning blocks, the two positioning pins are then inserted to check the positioning holes of the zipper reinforcement plate, the go / no-go gauge is used to check the circumferential space clearance, and finally the flatness of the cut edge of the zipper reinforcement plate is checked with a flatness gauge. The inspection of the zipper reinforcement plate can be completed in three simple standardized actions, which can effectively improve the inspection accuracy and inspection efficiency. Attached Figure Description
[0008] Figure 1 This is a structural schematic diagram of a zipper reinforcement plate inspection fixture according to the present invention;
[0009] Figure 2 This is a structural schematic diagram of a zipper reinforcement plate according to the present invention. Detailed Implementation
[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0011] Example:
[0012] like Figure 2 The zipper reinforcement plate shown includes four positioning surfaces 4 and two positioning holes 5. The positioning holes and positioning surfaces are named according to the product characteristics and are used to correspond to the development of inspection tools. The actual function of the positioning surfaces is to fit in accordance with the zipper, and the actual function of the positioning holes is to correspond to the mounting holes of the zipper.
[0013] like Figure 1 The zipper reinforcement plate inspection fixture shown includes a base 6, on which a protrusion 2 is fixed. The main body 2 has a groove in the middle, the inner contour of which fits the outer contour of the zipper standard part. The bottom of the groove has two pin holes and four positioning blocks 3. Two positioning pins 1 are inserted into the pin holes. It also includes a double-ended go / no-go gauge 7 with one end φ2.5mm and the other end φ3.5mm, and a flush gauge 8. A go / no-go gauge seat is fixed on the base, the go / no-go gauge seat including a silicone groove in the middle and four limiting pins at both ends. A flush gauge seat is fixed on the base, the flush gauge seat including a silicone groove.
[0014] The main body, go / no-go gauge seat, and flush gauge seat can all be made into fasteners that can be disassembled and assembled with the base by bolts, making them easy to replace. When the gauge is no longer in use, the base can also be recycled and used for other gauges.
[0015] The base can be made small enough to accommodate only the main body, the go / no-go gauge seat, and the flush gauge seat. This design is for easy portability. Therefore, the base has fixing holes and slots. Once in place, it can be fixed to the workbench using the fixing holes and slots.
[0016] The base also features a nameplate and reference coordinates, which are standard design elements and will not be elaborated upon further.
[0017] Working principle: Using positioning surface 4 as the reference surface, the zipper reinforcement plate is placed according to the shape of the inspection fixture. After placing the zipper reinforcement plate, positioning pin 1 is inserted for double positioning. Successful insertion of the positioning pin indicates a pass; failure to insert it indicates an error in the position or size of the positioning hole. A double-ended go / no-go gauge 7 is used to check the clearance between the corresponding peripheral surfaces and the space. If one end of the φ2.5 go / no-go gauge passes through while the other end does not, it is pass; conversely, otherwise it is fail. A ±0.5mm tolerance flush gauge 8 is used to check the corresponding cut edges. A clearance within ±0.5mm from the space is pass. During the inspection process, all parts must not be forcibly pressed in to avoid damage and human error.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
