When the device is used, the device is unfolded around the jig 1, and multiple functions of advancing, linkage, clutch transmission, control, fixing and the like are integrated. The back of the jig 1 is fixed with a supporting frame 4, round rods 6 are arranged on two sides of the bottom of the supporting frame 4 through supporting plates 5, and rollers 7 are arranged at two ends of each round rod 6 to roll. Meanwhile, a rotating rod 8 is arranged on the inner wall of the supporting frame 4, and driving wheels 9 are arranged on the surfaces of the rotating rod 8 and the round rod 6 and are connected through a driving belt 10.

In the aspect of a linkage mechanism, a transmission rod 12 is fixed at the rear end of the screw rod 2, the surface of the transmission rod 12 is connected with a transmission cylinder 13 in a sliding manner, the transmission cylinder 13 is connected with two supporting blocks 14 through bearings, and the supporting blocks 14 are fixed at the top of the supporting frame 4. When the transmission cylinder 13 rotates, the transmission rod 12 can be driven to rotate, and the transmission rod 12 drives the screw rod 2 to rotate, so that the movement of the positioning plate 3 is controlled. The clutch driving mechanism is realized by a double-shaft motor 27 on the inner wall of the support frame 4. The upper and lower output ends of the motor are fixed with a driving rod 15, and the surface of the driving rod 15 is connected with a bevel gear I16 in a sliding way. Wherein, the bevel gear I16 on the upper side is meshed with the bevel gear II 17 on the surface of the transmission barrel 13, and the bevel gear III 18 is arranged below the bevel gear I16 on the lower side. The position of the first bevel gear 16 on the driving rod 15 is controlled by the control mechanism, so that the first bevel gear 16 can be meshed with or separated from the second bevel gear 17 or the third bevel gear 18, and the driving path of the first bevel gear can be flexibly switched. The working principle of the control mechanism is that a connecting cylinder 19 is fixed on the inner side of a bevel gear I16, the surface of the connecting cylinder 19 is connected with a connecting ring 20 in a sliding way, and the connecting ring 20 is fixed with a linkage frame 21. When the linkage frame 21 moves, the connecting ring 20 is driven to move, and the bevel gear I16 slides downwards on the surface of the driving rod 15 through the connecting cylinder 19. Thus, the first bevel gear 16 on the upper side is disengaged from the second bevel gear 17, and the first bevel gear 16 on the lower side is engaged with the third bevel gear 18, thereby changing the transmission path. In terms of the fixing mechanism, clamping grooves 22 are formed in the upper side and the lower side of the back surface of the support frame 4, and clamping plates 23 are connected in a sliding mode in the upper clamping grooves 22.

For convenient operation, a handle 26 is also fixed to the back of the linkage frame 21. Through the handle 26, the user can conveniently drive the linkage frame 21 to move, and then the function switching of the control mechanism is realized. The positioning jig 1 for knuckle machining is prevented from being difficult to move and time-consuming and labor-consuming in manual operation, and has the advantage of being convenient to use.
In summary, when the steering knuckle processing positioning jig 1 is used, under the action of the travelling mechanism, the linkage mechanism, the clutch driving mechanism, the control mechanism and the fixing mechanism, the rotation of the screw rod 2 and the integral movement of the jig 1 can be driven electrically, so that the difficulty in moving the steering knuckle processing positioning jig 1 and the time and labor consumption of manual operation are avoided, and the steering knuckle processing positioning jig has the advantage of convenience in use.
