Specific implementation mode

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0026] As Figures 1-6 shown, an automatic fixture for an automotive steering column includes a mounting base plate 1 and a vertical plate 6. Two moving frames 3 are provided on the side wall of the vertical plate 6. A fixing mechanism for fixing the steering column is provided in the moving frame 3. The fixing mechanism includes a double-headed screw 7 rotatably connected to the side wall of the moving frame 3. The double-headed screw 7 and the output shaft of the motor 8 are engaged by two gears. Two clamping plates 10 are slidably connected to the inner wall of the moving frame 3. A motor 8 is provided on the side wall of the moving frame 3. An installation groove is provided on the side wall of the clamping plate 10, and a pressure sensor 19 is provided in the installation groove. Two control panels 9 are fixedly connected to the side wall of the vertical plate 6.

[0027] A placing mechanism for placing the steering column is provided on the mounting base plate 1. The placing mechanism includes an electric push rod 11 fixedly connected to the mounting base plate 1, and a placing plate 2 is installed at the output end of the electric push rod 11.

[0028] In the present utility model, a sliding groove 4 is opened at the upper end of the vertical plate 6. A movable plate 5 is fixedly connected to the side wall of the moving frame 3. Two screw rods 12 are fixedly connected to the side wall of the movable plate 5. Nuts 14 are provided on the screw rods 12, so that the position of the moving frame 3 can be adjusted, which is convenient for fixing different steering columns, thereby expanding the application range of the device.

[0029] In the present utility model, two vertical grooves are opened on the side wall of the vertical plate 6. Two rotating blocks 13 are fixedly connected to the side wall of the nut 14, which is convenient for rotating the nut 14.

[0030] In the present utility model, the cross section of the sliding groove 4 is T-shaped, which prevents the movable plate 5 from being pulled out horizontally, so that it only moves vertically. The movable plate 5 is slidably connected to the sliding groove 4.

[0031] In the present utility model, a mounting plate 15 is fixedly connected to the upper end of the upper moving frame 3. A fixed frame 18 is provided on the side wall of the mounting plate 15. A suction pipe 16 is provided on the fixed frame 18. The two ends of the suction pipe 16 are respectively connected with a suction hood 17 and a flange. The suction pipe 16 can be connected to an external suction device, so that the device can have the function of sucking away dust and smoke.

[0032] In the present utility model, the cross-section of the fixed frame 18 is L-shaped, and two bolts are provided on the side wall of the mounting plate 15, so that the suction hood 17 can be disassembled, facilitating transportation.

[0033] In the present utility model, the two clamping plates 10 are symmetrically distributed with respect to the central axis of the moving frame 3. The inner wall of the clamping plate 10 is provided with an arc surface, which can increase the contact area with the pipe column, making the clamping of the pipe column more firm.

[0034] In the initial state, the distance between the two clamping plates 10 at the same height becomes larger.

[0035] It should be noted that the present utility model is an automatic fixture for an automotive steering column. The user places the column part of the automotive steering column on the placing plate 2 and between the two lower clamping plates 10. Start the lower motor 8. The output shaft of the motor 8 drives the double-headed screw 7 to rotate through the transmission of two gears (shown in the figure). The two clamping plates 10 move towards each other to clamp the column. After placing the flared sleeve of the pipe column on the column and between the two upper clamping plates 10, start the upper motor 8 (the output shaft can rotate forward and backward, and the control method is one of the following: pulse control mode, analog control mode, communication control mode). The two clamping plates 10 move towards each other to clamp the side wall of the sleeve, and then the welding of the column and the sleeve can be carried out. After welding halfway, the motor 8 can be started, and the output shaft of the motor 8 rotates in reverse to loosen the column and the sleeve, rotate the column and the sleeve so that the unwelded part rotates to the front, and then start the motor 8 to fix the column and the sleeve, and continue welding. During the process, the automatic fixation of the column and the sleeve can be realized without manual fixation, thus improving the automation degree of the device;

[0036] For different automotive steering columns, the positions of the two moving frames 3 can be adjusted by loosening multiple nuts 14, facilitating the clamping of the pipe body and the sleeve of different automotive steering columns by the clamping plates 10 of the two moving frames 3, thereby expanding the application range of the device.
