A placement groove for placing the head of the part is provided on the positioning module. A longitudinal groove perpendicular to the placement groove is opened on the upper surface of the positioning module. The upper surface of the positioning module is flat on one side close to the placement groove. The extension bracket includes a base placed on the workbench and an extension arm connected to the base. The dial indicator is installed on the extension arm, and the extension arm can drive the dial indicator to contact the positioning module.

[0006] The extension arm of the utility model includes a main connecting rod, a sub-connecting rod and a clamping member. One end of the main connecting rod is rotatably connected to the base, the other end of the main connecting rod is connected to the sub-connecting rod through a rotating shaft, and the end of the sub-connecting rod is hinged to the clamping member.

[0007] Preferably, the clamping member includes a mounting clip and a mounting block connecting the mounting clip. A rotating shaft is provided at the end of the mounting block. The end of the sub-connecting rod is open, and a connecting rod is arranged between the openings. The connecting rod passes through the rotating shaft.

[0008] Further preferably, opposite openings are provided at the end of the mounting clip. The two openings are connected by a screw rod, and an adjusting nut is provided at the end of the screw rod.

[0009] The workbench of the utility model is made of stainless steel, and an electromagnet is built in the base.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The head of the L-shaped automotive part of the present utility model is placed in the placement groove of the positioning module, the shaft part of the part is placed in the vertical longitudinal groove, and the upper surface of the part just remains horizontal. By gently moving the dial indicator on the surface of the part, the flatness of the part surface is detected. If the generated horizontal deviation exceeds the set value, the part size is unqualified. The detection method is convenient and fast.

[0012] 2. The workbench is made of stainless steel, and an electromagnet is built into the base. The base can be stably installed on the workbench through magnetism, ensuring the stability of the detection work. Description of the Drawings

Detailed Embodiments

[0017] In order to more clearly and detailedly illustrate the object technical solution of the present utility model, the present utility model is further described below through relevant embodiments. The following embodiments are only for specifically illustrating the implementation method of the present utility model and do not limit the protection scope of the present utility model.

[0018] Embodiment 1

[0019] As Figure 1 and Figure 2 shown, an L-shaped automotive part size measuring device includes a positioning module 1, an extension bracket 2, a dial indicator 3, and a flat workbench 4. The positioning module 1 is provided with a placement groove 11 for placing the head of the part 5, and a longitudinal groove 12 vertically abutting the placement groove 11 is opened on the upper surface of the positioning module 1. The upper surface of the positioning module 1 near the placement groove 11 is flat. The extension bracket 2 includes a base 21 placed on the workbench 4 and an extension arm 22 connected to the base 21. The dial indicator 3 is installed on the extension arm 22, and the extension arm 22 can drive the dial indicator 3 to contact the positioning module 1.

[0020] Place the head of the L-shaped part 5 in the placement groove 11 of the positioning module 1, and place the shaft part of the part 5 in the vertical longitudinal groove 12. Place the positioning module 1 on the workbench 4, and the upper surface of the part 5 just remains horizontal. Pull the extension arm 22 so that the detection end of the dial indicator 3 just touches the upper surface of the head of the part 5.
