DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the utility model provides a detection device for welding the rear door window frame of an automobile, which includes a detection platform mechanism 1. Positioning mechanisms 2 are arranged on both the left and right sides of the detection platform mechanism 1. An automobile door body 3 is arranged on the top of the detection platform mechanism 1. A rear door window frame 4 of the automobile is fixedly welded to the right end of the automobile door body 3. The detection platform mechanism 1 includes a door placing plate 11. A sunken groove 12 that penetrates through from front to back is opened in the middle of the top end of the door placing plate 11. Placing bottom plates 13 are fixedly installed on both the left and right sides of the top of the door placing plate 11. Arc rubber pads 14 are fixedly installed on the top of the two placing bottom plates 13. An installation groove 15 that penetrates above the sunken groove 12 is opened in the middle of the bottom end of the door placing plate 11. A pressure detection mechanism 16 is arranged on the inner wall of the installation groove 15. Both positioning mechanisms 2 include extension plates 21. The two extension plates 21 are respectively fixedly installed on the left and right sides of the door placing plate 11. Positioning columns 22 are fixedly installed on the top of the two extension plates 21. Adjustment sliding grooves 23 are opened on the opposite surfaces of the two positioning columns 22. Positioning motors 24 are fixedly installed on the top of the two positioning columns 22. The output shafts of the two positioning motors 24 respectively penetrate into the inner cavities of the two adjustment sliding grooves 23 and are fixedly installed with threaded rods 25. Adjustment hanging plates 26 are threadedly installed on the outer walls of the two threaded rods 25. The two adjustment hanging plates 26 are respectively slidably connected to the inner walls of the two adjustment sliding grooves 23. On the side of the bottom of the two adjustment hanging plates 26 away from the positioning columns 22, lower pressing plates 27 are fixedly installed. Lower pressing rubber pads 28 are fixedly installed on the bottom of the two lower pressing plates 27. The two lower pressing rubber pads 28 are respectively located above the two arc rubber pads 14;

[0021] When it is necessary to detect the welding quality between the rear door window frame and the door body of the automobile, the automobile door body 3 and the rear door window frame 4 of the automobile are respectively placed on the arc rubber pads 14 on the placing bottom plates 13 on the left and right sides of the top of the door placing plate 11. Then, by simultaneously starting the positioning motors 24 at the top of the positioning columns 22 on the top of the two extension plates 21, the threaded rods 25 in the adjustment sliding grooves 23 opened on the two positioning columns 22 can be driven to rotate. Thus, in cooperation with the threaded connection with the adjustment hanging plates 26, the adjustment hanging plates 26 are driven to move downward. With the installed lower pressing plates 27 and the lower pressing rubber pads 28 at the bottom of the lower pressing plates 27, the automobile door body 3 and the rear door window frame 4 placed on the arc rubber pads 14 can be clamped and fixed downward, and the soft characteristics of the arc rubber pads 14 and the lower pressing rubber pads 28 are utilized to prevent the automobile door body 3 and the rear door window frame 4 from being damaged by pressing.

[0022] As Figure 4 shown, the pressure detection mechanism 16 includes an adjustment mechanism 161. The adjustment mechanism 161 is arranged on the inner wall of the installation groove 15. A hydraulic mechanism 162 is arranged above the adjustment mechanism 161. A top pressing plate 163 is arranged above the hydraulic mechanism 162;

[0023] After the car door body 3 is positioned, the hydraulic mechanism 162 above the lower adjusting mechanism 161 and the top pressing plate 163 included therein can cooperate to jack up the weld between the car door body 3 and the car window frame 4, and visually observe the welding quality between the car door body 3 and the car window frame 4 to check for cracking.

[0024] As Figure 5 shown, the adjusting mechanism 161 includes an adjusting box 1611. The four sides of the adjusting box 1611 are fixedly connected to the four inner side walls of the installation groove 15. A driving motor 1612 is fixedly installed on the left side of the inner wall of the adjusting box 1611. The output shaft of the driving motor 1612 is fixedly installed with a reciprocating lead screw 1613. The hydraulic mechanism 162 includes a hydraulic press 1621. Two hydraulic oil inlets 1622 are fixedly connected to the lower front side of the hydraulic press 1621. A T-shaped moving plate 1623 is fixedly installed at the bottom of the hydraulic press 1621. The front and rear sides of the vertical part of the T-shaped moving plate 1623 are lapped with the front and rear sides of the moving chute 1614. The vertical part of the T-shaped moving plate 1623 is threadedly connected to the outer wall of the reciprocating lead screw 1613. The top output end of the hydraulic press 1621 is fixedly connected to the center of the bottom of the top pressing plate 163;

[0025] By starting the driving motor 1612 in the adjusting box 1611, the reciprocating lead screw 1613 is driven to rotate. Cooperating with the threaded connection at the vertical part of the T-shaped moving plate 1623, the T-shaped moving plate 1623 can be driven to perform left and right reciprocating movement adjustment in the moving chute 1614 until the top pressing plate 163 at the top output end of the hydraulic press 1621 moves to the lower part of the weld between the car door body 3 to be detected and the car window frame 4. Then, the power supply of the driving motor 1612 can be manually turned off to stop the movement of the hydraulic press 1621. Then, the hydraulic oil inlet 1622 is connected to a oil pipe, and an external electric motor drives an external pump body to generate pressure, and the oil fluid is sent into the cylinder body included in the hydraulic press. Through the change in the sealing performance between the cylinder body and the piston, the energy is transmitted to the output end, so as to jack up the top pressing plate 163, squeeze the weld between the car door body 3 and the car window frame 4 upward, and penetrate the pressure value. According to the pressure value that the qualified window frame can withstand, adjustments are made. Once the pressure value is not reached, the car door body 3 and the car window frame 4 will crack or break, which means it is a welding unqualified product.

[0026] Next, the working principle of the detection device for welding the rear car window frame will be specifically described.

[0027] As Figures 1-5As shown in the figure, when it is necessary to detect the welding quality between the rear door window frame and the door body of the car, the car door body 3 and the car window frame 4 are respectively placed on the top of the arc rubber pads 14 on the placement bottom plates 13 on the left and right sides of the top of the car door placement plate 11. Then, by simultaneously starting the positioning motors 24 at the tops of the positioning columns 22 on the tops of the two extension plates 21, the threaded rods 25 in the adjustment sliding grooves 23 opened in the two positioning columns 22 can be driven to rotate. Thus, in cooperation with the threaded connection of the adjustment hanging plate 26, the adjustment hanging plate 26 is driven to move downward. With the installed lower pressing plate 27 and the lower pressing rubber pad 28 at the bottom of the lower pressing plate 27, the car door body 3 and the car window frame 4 placed on the arc rubber pads 14 can be clamped and fixed downward. By utilizing the soft characteristics of the arc rubber pads 14 and the lower pressing rubber pads 28, the car door body 3 and the car window frame 4 can be prevented from being bruised. Then, the drive motor 1612 in the adjustment box 1611 can be started, thereby driving the reciprocating lead screw 1613 to rotate. In cooperation with the threaded connection at the perpendicular position of the T-shaped moving plate 1623, the T-shaped moving plate 1623 can be driven to perform a reciprocating left and right movement adjustment in the moving sliding groove 1614 until the top pressing plate 163 at the output end of the top of the hydraulic press 1621 moves to the lower part of the welding joint of the car door body 3 and the car window frame 4 to be detected. At this time, the power supply of the drive motor 1612 can be manually turned off to stop the movement of the hydraulic press 1621. Then, by connecting a oil pipe to the hydraulic oil inlet 1622, an external electric motor drives an external pump body to generate pressure, and the oil liquid is sent into the cylinder body included in the hydraulic press. Through the change in the sealing performance between the cylinder body and the piston, the energy is transmitted to the output end, thereby jacking up the top pressing plate 163 upward to squeeze the weld joint of the car door body 3 and the car window frame 4 upward and penetrate the pressure value. According to the pressure value that the qualified window frame can withstand, adjustments are made. Once the car door body 3 and the car window frame 4 crack or break before reaching the qualified pressure value, they are unqualified welding products.

[0028] The above text generally describes the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are all within the protection scope of the present utility model.
