DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-Figure 4The automobile chassis control arm rapid quality inspection device shown in the figure is used for the quality inspection of the automobile chassis control arm 5. The appearance of the automobile chassis control arm 5 is as follows Figure 5 As shown, the characteristic is that two transverse holes 51 and one vertical hole 52 are provided on the automobile chassis control arm 5. A rapid quality inspection device for automobile chassis control arm comprises a tooling chassis 1, a fixed seat 2, a movable frame 3 and an insertion inspection column 4. The fixed seat 2 and the movable frame 3 are installed on the tooling chassis 1. The fixed seat 2 is fixedly installed. The movable frame 3 comprises a movable seat 31. The movable seat 31 and the fixed seat 2 are arranged on the same straight line. The movable seat 31 can move relative to or opposite to the fixed seat 2. The fixed seat 2 and the movable seat 31 are both connected with a positioning column 21. The two positioning columns 21 are relatively arranged The two transverse holes 51 of the automobile chassis control arm 5 can be installed on the two positioning posts 21 respectively. The diameter of the positioning post 21 needs to match the diameter of the transverse hole 51. If the transverse hole 51 cannot be installed into the positioning post 21, or it is very loose after installation, it is directly determined that the automobile chassis control arm 5 is unqualified. The tooling chassis 1 is provided with an insertion and inspection hole 11. After the automobile chassis control arm 5 is positioned and installed in the two transverse holes 51, the vertical hole 52 can just correspond to the position of the insertion and inspection hole 11. The diameter of the vertical hole 52, the diameter of the insertion and inspection hole 11 and the diameter of the insertion and inspection post 4 are matched. Figure 4 As shown, when the three-hole accuracy of the automobile chassis control arm 5 is qualified, the inspection column 4 can be inserted into the vertical hole 52 and the inspection hole 11 at the same time. If the inspection column 4 cannot be inserted into the vertical hole 52 and the inspection hole 11 at the same time, it proves that there is a large deviation between the positions of the vertical hole 52 and the two transverse holes 51. Such an automobile chassis control arm 5 cannot be installed smoothly during use and is directly judged as unqualified during quality inspection. The quality inspection operation of the utility model is very simple. Unqualified products can be quickly judged through the installation of the transverse hole 51 and the insertion operation of the inspection column 4. The utility model can meet the needs of rapid quality inspection of batch workpieces.

[0019] like Figure 2 and Figure 3 As shown, the movable frame 3 also includes a first vertical plate 32, a second vertical plate 33 and a translation driving push cylinder 35. The first vertical plate 32 and the second vertical plate 33 are installed in parallel. A guide rod 34 is connected between the first vertical plate 32 and the second vertical plate 33. The first vertical plate 32, the second vertical plate 33 and the guide rod 34 are combined to form a mounting frame for a movable seat 31. The movable seat 31 is inserted on the guide rod 34. The movable seat 31 can move along the length direction of the guide rod 34. The moving trajectory of the movable seat 31 is on the same straight line as the fixed seat 2. The movable seat 31 can move relative to or opposite to the fixed seat 2. When the movable seat 31 moves relative to the fixed seat 2, it can form an effect of clamping and positioning the control arm workpiece. After the movable seat 31 moves opposite to the fixed seat 2, the control arm can be disassembled and assembled. The translation driving push cylinder 35 is installed on the second vertical plate 33. The piston rod end of the translation driving push cylinder 35 is connected to the movable seat 31. The translation driving push cylinder 35 is used to drive the movable seat 31 to move.

[0020] like Figure 2 As shown, a limit screw 36 is threadedly installed on the first vertical plate 32, and the limit screw 36 is set on the movement trajectory of the movable seat 31. The limit screw 36 can be threaded to limit the movement stroke of the movable seat 31. During the clamping process of the control arm, if the positioning and clamping are excessive, the control arm will be deformed. After the deformation, the three-hole position of the control arm will deviate. In this case, the three-hole position quality inspection cannot be carried out. Therefore, the utility model installs a limit screw 36 to control the clamping movement distance of the movable seat 31. Before the quality inspection operation, a standard control arm is pre-installed, and the clamping movement limit of the movable seat 31 is limited by the size of the standard control arm. This ensures that the control arm will not be deformed during the subsequent clamping quality inspection, and the quality inspection operation can be carried out smoothly and accurately.

[0021] like Figure 1 As shown, an electromagnet 12 is installed on the tooling chassis 1. When the electromagnet 12 is turned on, it can form a magnetic attraction, so that the utility model can be firmly fixed on the iron workbench. The above design can facilitate the installation and fixing operation of the utility model.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
