[0015] The ball joint assembly tightening device inside the steering gear includes a frame 5, a conveying assembly 6, and a tightening assembly 7 (see the instruction manual appendix). Figure 1 and 2 ).

[0016] The conveyor assembly 6 is installed in the middle of frame 5 (see instruction manual appendix). Figure 1 and 2 The conveying assembly 6 includes a chain conveyor 25, a conveyor plate 26, a fixed bracket 27, a lifting cylinder 28, and a positioning hook plate 29 (see the attached instruction manual). Figure 3 ).

[0017] A chain conveyor 25 is installed in the middle of the frame 5; a conveyor plate 26 is mounted on the chain conveyor 25. The chain conveyor 25 and the conveyor plate 26 are purchased equipment; when the chain conveyor 25 is working, it can drive the conveyor plate 26 to move back and forth.

[0018] A fixed bracket 27 is provided on the conveyor plate 26. During operation, the workpiece to be installed (steering gear body) can be fixedly installed on the fixed bracket 27.

[0019] Multiple lifting cylinders 28 are installed in the middle of the chain conveyor 25; multiple positioning hook plates 29 are installed on both sides of the chain conveyor 25 above the lifting cylinders 28 (see the instruction manual attached with lifting cylinders 28). Figure 3During operation, when the chain conveyor 25 transports the conveyor plate 26 above the lifting cylinder 28, the lifting cylinder 28 actuates to lift the conveyor plate 26 until it contacts the positioning hook plate 29. At this time, the conveyor plate 26 will be clamped and fixed in place by the cooperation of the lifting cylinder 28 and the positioning hook plate 29.

[0020] Tightening components 7 are symmetrically mounted on the frames 5 on both sides of the conveyor assembly 6 (see the instruction manual appendix). Figure 1 and 2 ).

[0021] The tightening assembly 7 includes a translation slide plate 9, a mounting base 10, a slide plate pusher cylinder 8, a tightening gun 11, a guide plate 14, and a control wedge block 18.

[0022] A translation slide plate 9 is mounted on the frame 5 via a slide plate pusher cylinder 8; a tightening gun 11 is mounted on the translation slide plate 9 via a mounting base 10 (see instruction manual appendix). Figure 5 and 7 When the sliding plate cylinder 8 is working, it can move the mounting base 10 and the tightening gun 11 back and forth by shifting the sliding plate 9. The tightening gun 11 is an outsourced component.

[0023] A sliding seat 12 is slidably mounted on a guide rail on a sliding plate 9 on one side of the tightening gun 11; locking control cylinders 13 are mounted on both sides of the mounting base 10; the locking control cylinders 13 are connected to the sliding seat 12 (see the instruction manual appendix). Figure 5 When the locking control cylinder 13 is working, it can drive the sliding seat 12 to slide back and forth.

[0024] One end of the tightening gun 11 passes through the sliding seat 12 and is fixedly mounted with a guide plate 14; the center of the guide plate 14 is provided with a clearance hole 15; clamping blocks 16 are symmetrically slidably mounted on the clearance hole 15 via springs (see the instruction manual appendix). Figure 6 The clamping block 16 always tends to move outward under the action of the spring.

[0025] The inner side of the clamping block 16 is provided with a flat rectangular clamping surface 19; the outer side of the clamping block 16 is provided with a wedge-shaped pressure-bearing surface 20 (see the instruction manual appendix). Figure 6 and 9 ).

[0026] A rotating disk 17 is mounted inside the sliding seat 12 via bearings (see the instruction manual appendix). Figure 6 and 9 A control wedge block 18 is symmetrically hinged to the rotating disk 17; the wedge-shaped surface of the control wedge block 18 is slidably connected to the outside of the clamping block 16. The wedge-shaped surface of the control wedge block 18 is slidably connected to the wedge-shaped pressure surface 20 of the clamping block 16. During operation, the moving control wedge block 18 can press the wedge-shaped pressure surface 20 of the clamping block 16 with its wedge-shaped surface to make it move inward and complete the clamping work.

[0027] A sliding sleeve 21 is fitted onto the output end of the tightening gun 11 inside the clearance hole 15 of the guide plate 14; a clamping sleeve 22 is installed at one end of the sliding sleeve 21; a buffer spring 23 is installed on the tightening gun 11 at the other end of the sliding sleeve 21. A limit block 24 is bolted to the output end of the tightening gun 11 (see the instruction manual appendix). Figure 9 The limiting block 24 has the function of confining the sliding sleeve 21 to the output end of the tightening gun 11 to prevent it from disengaging; the sliding sleeve 21 and the clamping sleeve 22 always have a tendency to move towards the clamping block 16 under the action of the buffer spring 23.

[0028] The clamping assembly 30 and the adjusting assembly 31 are mounted on the frame 5 on one side of the tightening assembly 7 (see the instruction manual). Figure 4 ).

[0029] The clamping assembly 30 includes a clamping seat 32, clamping jaws 34, a push-pull cylinder 33, and a transmission swing arm 35. The clamping seat 32 is equipped with a push-pull cylinder 33; two sets of clamping jaws 34 are symmetrically hinged to one side of the clamping seat 32 on the push-pull cylinder 33; one end of each clamping jaw 34 is hinged to the output end of the push-pull cylinder 33 via the transmission swing arm 35 (see the attached instruction manual). Figure 4 ).

[0030] When the push-pull cylinder 33 is pulled backward, the transmission swing arm 35 can pull the clamping claws 34 to move so that they come together to clamp each other. When the push-pull cylinder 33 is pushed forward, the transmission swing arm 35 can push the clamping claws 34 to move so that they open.

[0031] Adjustment assembly 31 includes a parallel gripper 38, a push cylinder 36, and a conveyor plate 37; the conveyor plate 37 is mounted on the frame 5 via the push cylinder 36; the end of the conveyor plate 37 is equipped with a parallel gripper 38 (see the instruction manual appendix). Figure 4 When the push cylinder 36 is working, it can drive the conveyor slide 37 to slide back and forth.

[0032] When the steering gear inner ball joint assembly tightening device is in operation, the steering gear body to be installed is first mounted on the fixed bracket 27 of the conveyor plate 26 of the chain conveyor 25. Then, the inner ball joint is installed at both ends of the steering gear body by manual pre-assembly.

[0033] After the above operations are completed, the chain conveyor 25 drives the conveyor plate 26 to move the steering gear body to the middle of the two sets of tightening components 7 via the fixed bracket 27. Then, the lifting cylinder 28 actuates to lift the conveyor plate 26 until it contacts the positioning hook plate 29. At this time, the conveyor plate 26 will be clamped and fixed with the cooperation of the lifting cylinder 28 and the positioning hook plate 29. At this time, the spindles at both ends of the steering gear body are located inside the clamping jaws 34 of the clamping assembly 30.

[0034] After the above operations are completed, the push-pull cylinder 33 of the clamping assembly 30 pulls backward, causing the clamping jaws 34 to clamp and fix the spindle of the corresponding steering body. After the spindle is clamped and fixed, the push cylinder 36 of the adjusting assembly 31 pushes the parallel pneumatic gripper 38 to move through the conveying slide plate 37; when the ball rod 3 of the inner ball joint is inside the parallel pneumatic gripper 38, the push cylinder 36 stops moving. Then the parallel pneumatic gripper 38 moves to clamp, at which point the parallel pneumatic gripper 38 adjusts the ball rod 3 to a horizontal state; then the adjusting assembly 31 resets.

[0035] After the inner ball joint rod 3 of the steering gear is adjusted to a horizontal position, the sliding plate push cylinder 8 of the tightening assembly 7 is activated and drives the tightening gun 11 and other components to move towards the inner ball joint rod 3 through the translation sliding plate 9; when the inner ball joint rod 3 is inserted into the clearance hole 15, the sliding plate push cylinder 8 stops moving.

[0036] At this time, the inner ball joint rod 3 is inserted into the inside of the clamping sleeve 22 and the tightening gun 11; the flat square clamping surface 19 of the clamping block 16 corresponds to the flat square surface 4 of the ball seat 2; and the clamping sleeve 22 will overcome the elastic force of the buffer spring 23 and retract under the pressure of the ball seat 2, so the clamping sleeve 22 will always have the tendency to clamp the ball seat 2.

[0037] After the above steps are completed, the locking control cylinder 13 pushes the sliding seat 12 and the control wedge block 18 to move toward the clamping block 16; during this process, the control wedge block 18 can squeeze the wedge-shaped pressure surface 20 of the clamping block 16 through the wedge-shaped surface to make it move inward and complete the clamping work of the ball seat 2.

[0038] After the clamping block 16 clamps the ball seat 2, the tightening gun 11 rotates, causing the guide plate 14 and the clamping block 16 to rotate synchronously; during the rotation of the clamping block 16, the ball seat 2 can be rotated synchronously; thus, the tightening work of the ball seat 2 can be completed.

[0039] After the steering gear inner ball joint assembly and tightening device completes the inner ball joint assembly and tightening work, all components of the device are reset, and then a new workpiece is installed, allowing the tightening device to enter the next work cycle.

[0040] This steering gear internal ball joint assembly and tightening device has a compact structure and can mechanize the assembly and tightening process of the steering gear internal ball joint, thereby solving the problem of low assembly efficiency in the existing steering gear internal ball joint assembly method. It is particularly suitable for the needs of steering gear internal ball joint assembly and tightening.
