[0035] Please combine Figure 1 and Figure 2 The inspection fixture 1 for assisting vehicle door measurement of the present embodiment comprises a base 10 and a support frame 11. The support frame 11 is a hollow rectangular frame. The support frame 11 comprises two horizontal sides 111 and two vertical sides 112 connected end to end in sequence. The two horizontal sides 111 are horizontally arranged, and the two vertical sides 112 are vertically arranged on the base 10. A reference pin 12, a support structure 13, two zeroing reference fixtures 14 and two reference blocks 15 are arranged in between any of the vertical sides 112. The support structure 13 is close to the bottom of the vertical side 112. Two zeroing reference fixtures 14 are arranged at intervals along the vertical direction, and two reference blocks 15 are arranged at intervals along the vertical direction. The reference pins 12, the support structure 13, the zeroing reference fixtures 14 and the reference blocks 15 in the two vertical sides 112 are arranged in a one-to-one correspondence; the support structure 13 is used to support the vehicle door 50 to be measured, the zeroing reference fixture 14 is used to zero the reference surface of the vehicle door 50 and clamp the vehicle door 50, the reference pin 12 is used to abut against the vehicle door 50, and the reference block 15 is used to provide a coordinate system reference for measurement for an external measuring device.

[0036] In the technical solution of the utility model, a hollow rectangular frame is used as a support frame 11, and reference pins 12, a support structure 13, a zeroing reference fixture 14 and a reference block 15 are arranged on two vertical sides 112 of the support frame 11. The bottom of the vehicle door 50 is placed on the support structure 13, and then the vehicle door 50 is clamped and supported by the zeroing reference fixture 14. At the same time, the angle of the vehicle door 50 can also be fine-tuned to ensure the measurement accuracy. The reference pin 12 is used to abut the vehicle door 50 to support the vehicle door 50. The utility model simplifies the structure of the inspection fixture, uses a hollow rectangular frame as the support frame 11, and installs various support components on the vertical sides of the support frame 11, thereby reducing the inspection volume and weight while realizing the support function for the vehicle door 50. At the same time, the support frame 11 has less obstruction on the vehicle door 50, providing more measurement space for the vehicle door 50 and improving the measurement accuracy.

[0037] See also Figure 3 In one embodiment, the zeroing reference fixture 14 includes a connecting frame 141, an abutting block 142 and a clamping claw 143. One end of the connecting frame 141 is connected to the corresponding vertical side 112, and the other end is rotatably mounted with the abutting block 142. The clamping claw 143 is mounted on the abutting block 142. The abutting block 142 is used to abut against the surface of the vehicle door 50, and the clamping claw 143 is used to clamp the vehicle door 50. The abutting block 142 is rotatable, so that the abutting block 142 is rotated to abut against the vehicle door 50 to adjust the angle of the vehicle door 50, and then the vehicle door 50 is clamped by the clamping claw 143 to fix the vehicle door 50.

[0038] Furthermore, a threaded hole is provided on the abutment block 142, and the clamping claw 143 includes a bolt 144 and a clamping portion 145.

The bolt 144 passes through the first end 146 and the threaded hole in sequence and forms a clamping gap 148 with the second end 147. The bolt 144 is rotated to make the bolt 144 approach or move away from the second end 147 to adjust the size of the clamping gap 148. The size of the clamping gap 148 is adjusted by the bolt 144. After the clamping gap 148 is increased, the vehicle door 50 is extended into the clamping gap 148, and then the bolt 144 is rotated to move the bolt 144 toward the second end 147, so that the bolt 144 is clamped with the vehicle door 50, thereby achieving support for the vehicle door 50. At the same time, the vehicle door 50 is clamped and released by rotating the bolt 144. The structure is simple, the operation is convenient, and the adjustment efficiency is high.
