[0028] The pure electric circulating ball steering gear gap adjustment mechanism includes a detection component 4, a conveyor line 2, a frame 1, a workpiece clamp 40, an adjustment component 9 and a frame 1 (see the attached manual). Figure 1 and 2 ).
[0029] The frame 1 is equipped with a conveyor line 2 (see the attached manual). Figure 1 and 2 The conveyor line 2 is an externally purchased device, which can convey the workpiece holder 40 when in operation.
[0030] One end of the conveyor line 2 is equipped with a positioning component 3 (see the appendix of the instruction manual). Figure 1 and 2The positioning assembly 3 includes a positioning pressure plate 10, a lifting cylinder 11 and a lifting plate 12; the positioning pressure plate 10 is installed on the frame 1 on both sides of the conveyor line 2; the lifting plate 12 is installed below the positioning pressure plate 10 through the lifting cylinder 11 (see the appendix of the manual). Figure 8 During operation, when the conveyor line 2 conveys the workpiece clamp 40 to the bottom of the positioning plate 10, the lifting cylinder 11 drives the lifting plate 12 to move upward, which lifts the workpiece clamp 40 and separates it from the conveyor line 2. Then, with the cooperation of the positioning plate 10, the workpiece clamp 40 is clamped and fixed (see the appendix of the manual). Figure 8 ).
[0031] The detection component 4 is installed above the positioning component 3 (see the appendix of the instruction manual). Figure 1 、 2 and 3). The detection assembly 4 includes a detection bracket 13, a displacement detector 19, a horizontal slide 15, a longitudinal slide 16, a vertical slide 17, a manual screw 14 and a detection cylinder 18 (see the appendix of the manual). Figure 4 and 5 ).
[0032] A transverse slide 15 is mounted on the frame 1 via a detection bracket 13 and a manual screw 14. A longitudinal slide 16 is mounted on the transverse slide 15 via the manual screw 14 and guide rails. A vertical slide 17 is mounted on the longitudinal slide 16 via the manual screw 14 and guide rails. A displacement detector 19 is mounted on the vertical slide 17 via a detection cylinder 18. During operation, the positions of the detection cylinder 18 and displacement detector 19 can be adjusted using the manual screws 14, making it easy to adjust the position of the displacement detector 19, thereby adapting to the needs of inspecting a variety of workpiece models.
[0033] A traverse slide 5 is mounted on the frame 1 at one end of the positioning assembly 3 through a screw mechanism; a drive head 8 is mounted on the traverse slide 5 through a drive motor 6 and a torque sensor 7 (see the attached manual). Figure 2 and 3 ). A clamping groove is provided inside the driving head 8. When working, the driving head 8 can be clamped and connected with the arm shaft of the workpiece under the cooperation of the screw mechanism and the transverse slide 5.
[0034] The frame 1 below the positioning assembly 3 is equipped with an adjustment assembly 9 (see the appendix of the manual). Figure 1 、 2 and 3). The adjustment assembly 9 includes a screw mechanism 20, an adjustment slide 21, a lifting slide 22, an adjustment motor 27, an adjustment core rod 24, an adjustment head 29 and an adjustment sleeve 30 (see the appendix of the manual). Figure 9 、 10 and 11).
[0035] An adjustment slide 21 is mounted on the frame 1 below the positioning assembly 3 via a screw mechanism 20; a lifting slide 22 is mounted on the adjustment slide 21 via the screw mechanism 20; an adjustment core rod 24 is mounted on the lifting slide 22 via a bearing seat 23; an input shaft 25 is mounted below the adjustment core rod 24 via the bearing seat 23; the input shaft 25 is connected to the adjustment core rod 24 via a torque sensor 7; an adjustment motor 27 is mounted on the lifting slide 22 at one side of the lower end of the input shaft 25; the adjustment motor 27 is connected to the lower end of the input shaft 25 via a transmission belt 28 (see the appendix of the manual). Figure 9 and 10 The upper end of the adjusting core rod 24 is fixedly provided with an adjusting head 29. During operation, the adjusting motor 27 can drive the adjusting head 29 to rotate via the transmission belt 28, the input shaft 25 and the adjusting core rod 24.
[0036] The top of the adjustment head 29 is evenly distributed with a plurality of plug pins 26 (see the appendix of the specification). Figure 14 During operation, the adjusting head 29 can be inserted into the operating hole of the adjusting cock 39 through the plug pin 26, thereby driving the adjusting cock 39 to rotate and thereby achieve the purpose of adjusting the workpiece gap.
[0037] The outer side of the adjustment head 29 is provided with an adjustment sleeve 30; the top of the adjustment sleeve 30 is evenly distributed with a plurality of engaging teeth 37 (see the attached manual). Figure 14 During operation, the engaging teeth 37 of the adjusting sleeve 30 come into contact with the groove of the locking nut 38 on the workpiece, thereby driving the workpiece to rotate.
[0038] The lower end of the adjustment sleeve 30 is fixed with a transmission cylinder 31; a driving sleeve 34 is installed on the lifting slide 22 at the lower end of the transmission cylinder 31 through an auxiliary motor 32 and a reduction box 33; the driving sleeve 34 is slidably connected to the transmission cylinder 31 through a spline groove 35; a buffer spring 36 is installed between the driving sleeve 34 and the transmission cylinder 31 (see the appendix of the manual). Figure 9 、 10 and 11). The buffer spring 36 and drive sleeve 34 are provided for the following purposes: first, when the auxiliary motor 32 is in operation, it can drive the transmission cylinder 31 and the adjustment sleeve 30 to rotate via the reduction gear box 33 and drive sleeve 34. Second, when the adjustment sleeve 30 contacts the lock nut 38 on the workpiece, the elastic force of the buffer spring 36 forces the adjustment sleeve 30 to contact the lock nut 38 with a certain elastic force, thereby avoiding interference.
[0039] The pure electric recirculating ball steering gear clearance adjustment mechanism works by first fixing the workpiece to be adjusted on the workpiece clamp 40; then the conveyor line 2 conveys the workpiece clamp 40 to the bottom of the positioning plate 10. At this time, the lifting cylinder 11 drives the lifting plate 12 to move upward, which lifts the workpiece clamp 40 and separates it from the conveyor line 2. Then, with the cooperation of the positioning plate 10, the workpiece clamp 40 is clamped and fixed (see the appendix of the manual). Figure 8 ).
[0040] After the above process is completed, the screw mechanism 20 and the lifting slide 22 of the adjustment assembly 9 cooperate to move the adjustment head 29 and the adjustment sleeve 30 upward. When the engaging teeth 37 of the adjustment sleeve 30 contact the retaining grooves of the lock nut 38 on the workpiece, and the adjustment head 29 is inserted into the adjustment cock 39 via the plug pin 26, the lifting slide 22 stops moving upward.
[0041] Subsequently, when the auxiliary motor 32 is in operation, it can drive the transmission cylinder 31 and the adjustment sleeve 30 to rotate through the reduction gear box 33 and the drive sleeve 34, thereby loosening the lock nut 38. Then, the adjustment motor 27 can drive the adjustment head 29 and the adjustment plug 39 to rotate through the transmission belt 28, the input shaft 25 and the adjustment core rod 24, thus completing the adjustment of the adjustment plug 39. The adjustment sleeve 30 then rotates to tighten the lock nut 38. At this point, the adjustment assembly 9 completes the adjustment of the adjustment plug 39, and the various components of the adjustment assembly 9 are reset.
[0042] After the components of the adjustment assembly 9 are reset, the adjustment detection cylinder 18 of the detection assembly 4 drives the displacement detector 19 downward, bringing it into contact with the workpiece's input shaft. The drive head 8, in conjunction with the screw mechanism and the transverse slide 5, then engages the workpiece's arm shaft and drives the arm shaft to rotate. During this process, the displacement detector 19 detects the workpiece gap. After the test is complete, the drive head 8 and displacement detector 19 are reset. The gap adjustment mechanism then adjusts the regulating plug 39 again through the adjustment assembly 9 based on the detection results of the displacement detector 19. In this way, the detection assembly 4, drive head 8, and adjustment assembly 9 cooperate with each other and repeat the above-mentioned actions to complete the gap adjustment of the pure electric recirculating ball steering gear.
[0043] The pure electric recirculating ball steering gear gap adjustment mechanism has a compact structure and ingenious design. It can mechanically complete the gap adjustment of the pure electric recirculating ball steering gear, thereby solving the problem of low adjustment efficiency of the existing pure electric recirculating ball steering gear gap adjustment method. It is particularly suitable for the needs of pure electric recirculating ball steering gear gap adjustment.
