[0012] The assembly device for the motor and belt of the automotive steering system includes a motor assembly assembly 3, a belt assembly assembly 4, a frame 2, and a conveyor assembly 1 (see the attached instruction manual). Figure 1 ).

[0013] Conveying assembly 1 includes a conveyor 16, a workpiece clamp 17, a fixing frame 18, a lifting cylinder 20, and a positioning hook plate 19 (see the attached instruction manual). Figure 1 ).

[0014] The conveyor 16 is equipped with a workpiece clamp 17; symmetrical positioning hook plates 19 are mounted on the conveyor 16; a lifting cylinder 20 is installed inside the conveyor 16 inside the positioning hook plate 19 (see the instruction manual appendix). Figure 1 ).

[0015] The conveyor 16 is an externally purchased component. When the conveyor 16 is working, it can drive the workpiece clamp 17 to move. When the workpiece clamp 17 moves to the lifting cylinder 20, the lifting cylinder 20 can clamp and fix the workpiece clamp 17 with the cooperation of the positioning hook plate 19.

[0016] The workpiece clamp 17 is equipped with a fixing bracket 18 (see the instruction manual appendix). Figure 1 The workpiece steering assembly is mounted on the mounting bracket 18 (see the instruction manual appendix). Figure 1 ).

[0017] The motor assembly assembly 3 and the belt assembly assembly 4 are mounted on the frame 2 on one side of the conveyor assembly 1 (see the instruction manual appendix). Figure 1 ).

[0018] The belt assembly assembly 4 includes a support fork plate 12, a mounting bracket 5, a lifting cylinder 6, a positioning pressure head 8, a shifting head 10, and a push-pull cylinder 9 (see the instruction manual appendix). Figure 2 and 3 ).

[0019] A lifting seat 7 is mounted on the frame 2 via a mounting bracket 5 and a lifting cylinder 6; a positioning pressure head 8 is mounted at the bottom of the lifting seat 7. An actuating head 10 is slidably mounted on the bottom of the lifting seat 7 on one side of the positioning pressure head 8 via a push-pull cylinder 9 and a guide rail (see the instruction manual appendix). Figure 2 and 3 When the push-pull cylinder 9 is working, it can push the actuating head 10 to move back and forth along the guide rail.

[0020] The actuating head 10 includes a base sleeve 13, a floating pin 14, and a buffer spring; the base sleeve 13 is slidably mounted on the bottom of the lifting seat 7 via a push-pull cylinder 9 and a guide rail; the floating pin 14 is mounted on the bottom of the base sleeve 13 via a buffer spring (see the attached instruction manual). Figure 4 When the floating pin 14 is compressed, it can overcome the elastic force of the buffer spring and retract into the interior of the base sleeve 13.

[0021] A support fork plate 12 is mounted on the mounting bracket 5 below the lifting seat 7 via a drive cylinder 11 (see instruction manual appendix). Figure 2 ).

[0022] Motor assembly 3 includes an electric carriage 21, a positioning fork plate 22, and a clamping cylinder 23 (see instruction manual appendix). Figure 1 and 5The frame 2 is equipped with a positioning fork plate 22 via an electric slide 21.

[0023] The electric slide 21 includes an electric transverse lead screw 28, a transverse slide block 29, a lifting cylinder 26, a lifting slide 27, a longitudinal cylinder 24, and a longitudinal slide 25; the longitudinal slide 25 is mounted on the frame 2 via the longitudinal cylinder 24; the lifting slide 27 is mounted on the longitudinal slide 25 via the lifting cylinder 26; the transverse slide block 29 is mounted on the lifting slide 27 via the electric transverse lead screw 28; and a positioning fork plate 22 is mounted on the transverse slide block 29 (see the attached instruction manual). Figure 5 During operation, the longitudinal cylinder 24, the lifting cylinder 26, and the electric transverse lead screw 28 work together to drive the positioning fork plate 22 to move along the trajectory.

[0024] The positioning fork plate 22 is provided with a positioning fork opening 15; a clamping cylinder 23 is installed below the positioning fork plate 22 (see the instruction manual). Figure 5 ).

[0025] When the motor and belt assembly device of the automotive steering gear is working, the conveyor 16 drives the workpiece clamp 17 to move above the lifting cylinder 20. Subsequently, the lifting cylinder 20, with the cooperation of the positioning hook plate 19, clamps and fixes the workpiece clamp 17. At this time, the workpiece steering assembly is located below the positioning pressure head 8.

[0026] After the above steps are completed, the drive cylinder 11 drives the support fork plate 12 to insert below the steering gear assembly pulley (see the instruction manual appendix). Figure 6 At this point, the belt to be assembled is manually placed on the support fork plate 12, with the pulley located inside the belt. After the belt is placed, the lifting cylinder 6 drives the lifting seat 7 to move down a certain distance, causing the positioning pressure head 8 to contact the upper surface of the belt, and the floating pin 14 of the actuating head 10 is inserted into the belt. At this point, the belt is located between the positioning pressure head 8 and the support fork plate 12; the positioning pressure head 8 and the support fork plate 12 serve to limit the belt and prevent it from disengaging from the pulley.

[0027] After the floating pin 14 is inserted into the inside of the belt, the push-pull cylinder 9 pushes the actuating head 10 to move, causing it to pull the belt through the floating pin 14; the floating pin 14 stops moving when it moves above the motor mounting position of the workpiece steering assembly.

[0028] After the floating pin 14 moves above the motor mounting position of the workpiece steering assembly, the motor to be assembled is manually placed on the positioning fork 15 of the positioning fork plate 22; then the clamping cylinder 23 clamps and fixes the motor. After the motor is clamped and fixed, the longitudinal cylinder 24, lifting cylinder 26 and electric transverse screw 28 of the electric slide 21 cooperate to move the motor below the motor mounting position of the workpiece steering assembly; then the motor moves upward, during which the output end of the motor presses the floating pin 14 to retract it into the interior of the base sleeve 13; at this time, the output end of the motor is located inside the belt, and the assembly surface of the motor is in contact with the motor mounting position of the workpiece steering assembly. Then the screw is manually installed to install the motor on the steering assembly.

[0029] After the above work is completed, the lifting cylinder 6 drives the positioning pressure head 8 and the actuating head 10 to move up and reset; the clamping cylinder 23 releases the motor, and then the electric slide 21 drives the positioning fork plate 22 to reset; at this point, the assembly device has completed the assembly of the motor and belt; then the conveying component 1 drives the new workpiece to move below the belt assembly component 4, and the assembly device can enter the next work cycle.

[0030] The assembly device for the motor and belt of the automotive steering system is compact and ingeniously designed, enabling the mechanized assembly of the motor and belt of the automotive steering system. This solves the problem of low work efficiency in existing installation methods and is particularly suitable for the needs of automotive steering system assembly.
