[0013] Figure 4 This is a structural schematic diagram of the left front wheel arch reinforcement. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0015] Example:
[0016] like Figure 4 The left front wheel cover reinforcement 80 shown has multiple surfaces, including a mounting plane on the right half that is in close contact with the left front wheel cover during installation. The right side of the mounting plane has a mounting hole I11. The left half of the reinforcement arches upward to form a cover shape. The top of the left half has a mounting hole II12, and the arched left half also has a groove 13.
[0017] like Figure 1 , 2 A left front wheel arch reinforcement fixture, as shown in Figure 3, includes a chassis 8, a main body 7 fixed at the center of the chassis, and a strip-shaped recess on the top left side of the main body, the outline of which corresponds to the groove 13 on the left side of the left front wheel arch reinforcement. The top surface of the main body includes multiple surfaces, the outline of which matches the bottom outline and a side outline of the left front wheel arch reinforcement. Positioning blocks I4 and II5 are provided at the bottom of the recess. A positioning pin hole I1 is provided on the top right side of the main body, and a positioning pin I is configured in the positioning pin hole I. A positioning pin hole II2 is provided on the top left side of the main body. Hole II is equipped with positioning pin II. Positioning block III 6 is provided at the upper right corner of the right part of the main body, and positioning block IV 3 is provided at the lower right corner of the right part of the main body. A first quick clamp 41 is installed on the left side of the chassis, and a second quick clamp 31 and a third quick clamp 61 are installed on the right side of the chassis. When the first quick clamp 41 is closed, the clamp head of the first quick clamp is located between positioning block I and positioning block II. When the second quick clamp is closed, the clamp head of the second quick clamp is located on positioning block III. When the third quick clamp is closed, the clamp head of the third quick clamp is located on positioning block IV. The chassis is also provided with a go / no-go gauge seat and a flush gauge seat. The go / no-go gauge seat is provided with a go / no-go gauge 9, and the flush gauge seat is provided with a flush gauge 10.
[0018] Furthermore, a raised edge is provided on one side of the main body to further enhance the user experience and make it faster and more convenient to insert parts.
[0019] Further, the first fast clamping chuck is a square block-shaped chuck, which is convenient for positioning the workpiece in the recess.
[0020] Further, the through-and-stop gauge is a through 2.5 to stop 3.5 gauge.
[0021] Further, the tolerance of the flush gauge is ±0.5mm.
[0022] Working principle: open all the fast clamps, so that they are in a non-working state, and position the block I, the block II, the block III and the block IV as the reference surface of the part, and place the part according to the shape of the gauge, and then insert the positioning pin I to make primary positioning and insert the positioning pin II to make secondary positioning, and then close all the fast clamps, so that the fast clamps are in a working state, and then use the through 2.5 to stop 3.5 gauge 9 to detect the corresponding peripheral surface from the space gap, and the through 2.5 is qualified, and the same is true for the unqualified. Use the ±0.5mm flush gauge 10 to measure the corresponding cutting edge surface from the space gap, and the space gap is qualified within ±0.5mm. During the process of placing the part, the part and the pin cannot be forced to be pressed in, and no scratching phenomenon is observed at other positions. If the positioning pin I and the positioning pin II cannot be inserted, it indicates that the installation hole I and the installation hole II on the part are deviated too much.
