[0014] The steering belt tension adjustment device includes a conveyor 1, a frame 2, an adjuster 4, and a detector 3 (see the instruction manual appendix). Figure 1 ).

[0015] The conveyor 1 includes a chain conveyor 26, a conveyor clamp 27, a lifting cylinder 30, a fixed hook plate 29, and a positioning bracket 28.

[0016] The chain conveyor 26 is equipped with multiple conveyor clamps 27; each conveyor clamp 27 is equipped with a positioning bracket 28. The positioning bracket 28 includes a positioning sleeve 31, an assembly plate 32, and a positioning plate 33; the conveyor clamp 27 is equipped with the positioning sleeve 31; one side of the positioning sleeve 31 is equipped with the assembly plate 32; the top of the assembly plate 32 is equipped with the positioning plate 33; the positioning plate 33 is provided with a positioning slot 34.

[0017] The steering gear to be adjusted can be placed on the positioning bracket 28; at this time, the bottom of the steering gear is connected to the positioning sleeve 31, and the upper end is engaged with the positioning slot 34.

[0018] The chain conveyor 26 is symmetrically equipped with fixing hook plates 29 (see the instruction manual). Figure 9 A lifting cylinder 30 is installed on the chain conveyor 26 below the fixed hook plate 29 (see the instruction manual appendix). Figure 1 ); the fixed hook plate 29 corresponds to the detector 3.

[0019] During operation, when the chain conveyor 26 drives the conveyor clamp 27 to move to correspond with the detector 3, the lifting cylinder 30 pushes the conveyor clamp 27 upward so that it is clamped and fixed with the cooperation of the fixed hook plate 29 (see the instruction manual appendix). Figure 1 and 9 ).

[0020] A detector 3 is mounted on one side of the conveyor 1 via the frame 2 (see instruction manual appendix). Figure 1The detector 3 includes a tightening assembly 18, a lifting platform 17, a lifting screw 16, a positioning clamping claw 19, a pushing cylinder 20, and a detection probe 21 (see the instruction manual appendix). Figure 2 , 4 and 6).

[0021] A lifting platform 17 is mounted on the frame 2 via a lifting motor 15 and a lifting screw 16. When the lifting motor 15 is working, it can drive the lifting platform 17 to move up and down via the lifting screw 16.

[0022] The lifting platform 17 is equipped with a tightening assembly 18 in the middle (see instruction manual). Figure 2 The tightening assembly 18 includes an electric cross slide 22, a vertical cylinder 23, and a tightening gun; the vertical cylinder 23 is mounted on the middle of the lifting platform 17 via the electric cross slide 22; the tightening gun is mounted at the bottom of the vertical cylinder 23 (see the attached instruction manual). Figure 4 During operation, after the steering belt tension adjustment device completes the tension adjustment of the workpiece, the electric cross slide 22 and the vertical cylinder 23 will cooperate to drive the tightening gun to complete the tightening of the workpiece nut.

[0023] The lifting platform 17 is symmetrically equipped with positioning and clamping claws 19 at one end of its lower side (see instruction manual). Figure 6 When the lifting platform 17 moves downward, the workpiece can be pressed and fixed by the positioning clamping claw 19.

[0024] A detection probe 21 is mounted on the bottom of the lifting platform 17 on one side of the positioning clamping claw 19 via a push cylinder 20. The detection probe 21 is an externally purchased device, model CLV060; during operation, the push cylinder 20 can detect the tension of the workpiece belt by pushing the detection probe 21 to press the belt on the workpiece.

[0025] One end of the lifting platform 17 is equipped with a clamping cylinder 25 via a lifting cylinder 24 (see instruction manual appendix). Figure 5 and 6 The operation involves clamping the mandrel at the upper end of the workpiece with the clamping cylinder 25, and then lifting the mandrel to move it up a certain position by pulling it with the clamping cylinder 25.

[0026] The adjuster 4 is located below detector 3 (see instruction manual). Figure 1 The adjuster 4 includes a horizontal lead screw 6, a vertical lead screw 9, a lifting slide 10, a swing slide plate 12, and a clamping cylinder 13 (see the instruction manual appendix). Figure 8 ).

[0027] A transverse slide 7 is mounted on the frame 2 via a transverse motor 5 and a transverse lead screw 6; a lifting slide 10 is mounted on the transverse slide 7 via a vertical motor 8 and a vertical lead screw 9.

[0028] A swing slide plate 12 is mounted on the lifting slide 10 via an arc-shaped guide rail 11; a clamping cylinder 13 is mounted on the swing slide plate 12; a drive gear is mounted on the lifting slide 10 at one end of the swing slide plate 12 via a drive motor 14; the drive gear meshes with an arc-shaped rack at one end of the swing slide plate 12 (see the attached manual). Figure 8 When the drive motor 14 is working, it can drive the swing slide plate 12 to swing back and forth along the arc-shaped guide rail 11 through the drive gear.

[0029] When the chain conveyor 26 transports the pre-installed conveyor clamp 27 to the location corresponding to the detector 3, the lifting cylinder 30 is activated and finally clamps and fixes the conveyor clamp 27 with the cooperation of the fixed hook plate 29.

[0030] After the above actions are completed, the lifting motor 15 on the detector 3 operates and drives the lifting platform 17 to move down a certain distance through the lifting screw 16, so that the positioning clamping claw 19 clamps and fixes the workpiece.

[0031] After the positioning clamping claw 19 clamps and fixes the workpiece, the push cylinder 20 pushes the detection probe 21 to clamp the belt on the workpiece and detect its tension. After detection, it is reset.

[0032] After the tension test is completed, the horizontal motor 5 and the vertical motor 8 of the adjuster 4 cooperate with each other to clamp the motor housing of the workpiece by the clamping cylinder 13; then the drive motor 14 drives the swing slide plate 12 to swing through the drive gear, so that the clamping cylinder 13 can drive the motor of the workpiece to swing to complete the initial adjustment work.

[0033] Subsequently, the push cylinder 20 pushes the detection probe 21 to press the belt on the workpiece, and its tension is tested again. If it is not qualified, the adjuster 4 will swing and adjust the motor of the workpiece again until it is qualified.

[0034] After the above operations are completed, the clamping cylinder 25 clamps the mandrel at the upper end of the workpiece, and the lifting cylinder 24 pulls the mandrel upwards by passing through the clamping cylinder 25. Then, the pushing cylinder 20 pushes the detection probe 21 to press the belt on the workpiece, detects its tension, and then resets. After that, the adjuster 4 adjusts the motor of the workpiece by swinging it. After the adjustment is completed, the detection probe 21 and the adjuster 4 repeat the above actions until the motor of the workpiece is adjusted to the appropriate position.

[0035] After the above work is completed, the electric cross slide 22 and vertical cylinder 23 in the tightening assembly 18 will cooperate to drive the tightening gun to complete the tightening of the workpiece nut. At this point, the steering belt tension adjustment device has completed the adjustment of the steering belt tension. After all components of the adjustment device are reset, the adjustment device can enter the next working cycle.

[0036] This steering belt tension adjustment device has a compact structure and ingenious design. It does not require manual clamping and tightening and can continuously complete the steering belt tension adjustment action. It solves the problems of high labor intensity and inability to work continuously in existing steering belt tension adjustment devices, and is particularly suitable for the needs of steering belt tension adjustment.
