In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0024] As Figure 1 、 2 、shown in FIG. 4, an inspection device for automobile bumper production includes an inspection table 101. Support legs 102 are arranged at the bottom of the inspection table 101. An installation groove 103 with an open top is arranged along the left-right direction on the top of the inspection table 101. A bidirectional screw 104 is rotatably arranged between the left and right ends of the installation groove 103. The right end of the bidirectional screw 104 extends to the outside of the right end of the installation groove 103. Installation blocks 105 that are slidably connected to the installation groove 103 are respectively screwed at both ends of the bidirectional screw 104. A support block 106 adapted to the bumper is jointly arranged at the tops of the two installation blocks 105. An auxiliary support module is also arranged between the two installation blocks 105 and the inspection table 101. A driving module for rotationally driving the bidirectional screw 104 is arranged at the right end of the installation groove 103. First telescopic push rods 107 are vertically arranged at the top corners of the inspection table 101. A top plate 108 is jointly arranged at the tops of the output shafts of the four first telescopic push rods 107. A protective cover 109 capable of covering the outside of the installation groove 103 is arranged at the bottom of the top plate 108. A plurality of second telescopic push rods 110 are vertically arranged on the top plate 108. Impact blocks 111 are arranged at the lower ends of the output shafts of the plurality of second telescopic push rods 110.

[0025] As Figure 2 shown in FIG., bearing 112 is respectively arranged on the inner side walls of the left and right ends of the installation groove 103, and both ends of the bidirectional screw 104 are respectively connected to the inner rings of the corresponding bearings 112.

[0026] As Figure 2 shown in FIG., the driving module includes a U-shaped fixing frame 201 arranged at the right end of the mounting frame. A driving motor 202 is horizontally arranged at the right end of the fixing frame 201.

Then, the bidirectional screw rod 104 can be rotated and adjusted by the driving motor 202, so as to adjust the positions of the two mounting blocks 105 on the mounting groove 103, and further enable the support block 106 to better support and place the bumper. When the adjustment of the position of the mounting block 105 is completed, the output shaft of the third telescopic push rod 302 can be extended downward by a certain length, so that the support cushion block 303 abuts against the detection table 101, thereby assisting in supporting the mounting block 105 and preventing the bidirectional screw rod 104 from being deformed and damaged due to the direct bearing of all the downward forces by the mounting block 105 during the subsequent detection of the bumper.

[0029] Subsequently, the bumper can be placed on the two placement tables. Then, the output shaft of the first telescopic push rod 107 can be shortened downward by a certain length, so that the protective cover 109 moves downward and abuts against the top of the detection table 101, thereby isolating and protecting the bumper to be detected subsequently through the protective cover 109 and the top plate 108. Then, the output shaft of the second telescopic push rod 110 can be extended downward by a certain length, so that the impact block 111 moves downward at a certain speed, thereby impacting the bumper and further performing an impact test on the bumper. Then, the impact block 111 can be reset upward by the second telescopic push rod 110, and the top plate 108 and the protective cover 109 can be reset upward by the first telescopic push rod 107. Then, the monitored bumper can be taken away.
