Technical Field

[0001] This invention relates to an assembly device for a dust cover for the outer ball joint of an automotive steering gear, belonging to the field of automotive parts manufacturing technology. Background Technology

[0002] Dust covers are mounted on the outer ball joint of automotive steering gears via small and large retaining rings. Before installation, the axial clearance of the outer ball joint needs to be checked. After passing the inspection, the small and large retaining rings and dust covers are assembled. Currently, the assembly of dust covers for automotive steering gear outer ball joints is done manually with the aid of equipment, resulting in low work efficiency. Therefore, it is necessary to develop a new assembly device that can mechanize the assembly of dust covers for automotive steering gear outer ball joints, thereby solving the above-mentioned problems of the existing assembly method.

Detailed Implementation

[0049] The assembly device for the dust cover of the outer ball joint of the automotive steering gear includes a frame 1, an assembly indexing plate 2, a workpiece support 3, an axial clearance detector 6, a detection cone sleeve 5, a leveling device 7, a grease injector 8, a small retaining ring dust cover assembler 9, a dust cover assembler 10, a large retaining ring assembler 11, an airtightness detector 12, and a cone sleeve returner 13 (see the instruction manual appendix). Figure 1 and 2 ).

[0050] The frame 1 is equipped with an assembly indexing plate 2; multiple workpiece support seats 3 are evenly distributed on the assembly indexing plate 2; a detection cone sleeve 5 is mounted on the indexing plate inside the workpiece support seat 3 via a support rod 4 (see instruction manual appendix). Figure 1 and 3The bottom of the testing cone sleeve 5 is provided with a positioning cone hole 14; a vent hole 15 is provided above the positioning cone hole 14 (see the instruction manual appendix). Figure 4 ).

[0051] A tapered sleeve manipulator 35 is mounted on the frame 1 inside the indexing plate 2 on one side of the axial clearance detector 6 (see instruction manual appendix). Figure 33 The shape of the positioning cone hole 14 is consistent with the shape of the outer ball joint of the car steering gear. During operation, the cone sleeve manipulator 35 can put the detection cone sleeve 5 on the top of the outer ball joint of the car steering gear through the positioning cone hole 14.

[0052] The axial clearance detector 6, the leveling device 7, the grease injector 8, the small retaining ring dust cover assembler 9, the dust cover assembler 10, the large retaining ring assembler 11, the airtightness detector 12, and the tapered sleeve returner 13 are sequentially installed on the frame 1 around the indexing plate 2. The axial clearance detector 6, the leveling device 7, the grease injector 8, the small retaining ring dust cover assembler 9, the dust cover assembler 10, the large retaining ring assembler 11, the airtightness detector 12, and the tapered sleeve returner 13 correspond to the workpiece support 3 respectively (see the instruction manual appendix). Figure 1 and 2 ).

[0053] The axial clearance detector 6 includes a detection indexing plate 16, a detection support 18, a clearance detection assembly 23, a transverse slide 20, a support column 29, a detection clamp 21, and a rotary locking head 27 (see the instruction manual appendix). Figure 5 ).

[0054] The inspection indexing plate 16 is mounted on the frame 1 on one side of the assembly indexing plate 2; the inspection support base 18 is movably mounted on the inspection indexing plate 16 via the base 17 (see the instruction manual appendix). Figure 6 ).

[0055] A transverse slide 20 is mounted on the frame 1 on one side of the indexing plate 16 via a transverse cylinder 19; a detection clamp 21 is fixedly mounted on the transverse slide 20; a workpiece slot 22 is provided in the middle of the detection clamp 21; gap detection components 23 are mounted on the detection clamps 21 on both sides of the workpiece slot 22 (see the instruction manual appendix). Figure 32 ).

[0056] The gap detection assembly 23 includes a detection probe 31, a rotating swing arm 30, an anti-wear roller 33, a control plate 34, and a displacement sensor 32. The rotating swing arm 30 is hinged to the detection clamps 21 on both sides of the workpiece slot 22. One end of the rotating swing arm 30 is equipped with the detection probe 31. The weight of the end of the rotating swing arm 30 equipped with the detection probe 31 is greater than that of the other end. Therefore, the rotating swing arm 30 always tends to rotate towards the workpiece slot 22. The detection probe 31 extends into the interior of the workpiece slot 22. A displacement sensor 32 is installed between the rotating swing arm 30 on one side of the detection probe 31 and the detection clamp 21. The other end of the rotating swing arm 30 is equipped with an anti-wear roller 33. A control plate 34 is mounted above the anti-wear roller 33 via a cylinder. The control plate 34 is in rolling connection with the anti-wear roller 33 (see the attached instruction manual). Figure 9 When the pressure plate 34 moves up and down, it can drive the rotating swing arm 30 to swing as required.

[0057] A lifting slide 25 is mounted on the transverse slide 20 above the detection clamp 21 via a lifting cylinder 24; a rotating locking head 27 is mounted on the lifting slide 25 via a rotating cylinder 26; a support column 29 is mounted on the transverse slide 20 below the detection clamp 21 via a lifting cylinder 28 (see the instruction manual appendix). Figure 8 ).

[0058] When the axial clearance detector 6 is working, the workpiece first needs to be placed on the detection support 18 of the detection indexing plate 16. When the detection indexing plate 16 moves the workpiece to the position corresponding to the transverse slide 20 through the detection support 18, the transverse cylinder 19 moves the transverse slide 20 a certain distance, so that the detection support 18 and the workpiece are located between the support column 29 and the detection clamp 21.

[0059] After the above work is completed, the lifting cylinder 28 presses the detection support 18 and the workpiece upward through the support column 29, so that the outer ball joint of the workpiece is finally clamped and fixed with the cooperation of the workpiece slot 22 of the detection clamp 21 (see the instruction manual appendix). Figure 9 Then, the control plate 34 moves upward, causing the rotating swing arm 30 to swing towards the workpiece, and finally bringing the detection probe 31 into contact with the ball head of the outer ball joint of the workpiece (see the instruction manual appendix). Figure 9 ).

[0060] After the detection probe 31 contacts the ball head of the outer ball joint of the workpiece, the lifting cylinder 24 drives the rotating cylinder 26 and the rotating locking head 27 to move down through the lifting slide 25; during the downward movement of the rotating locking head 27, the rotating cylinder 26 drives it to rotate, so that the rotating locking head 27 can maintain a threaded connection with the upper end of the outer ball joint of the workpiece.

[0061] After the rotary locking head 27 is threadedly connected to the upper end of the workpiece outer ball joint, the lifting cylinder 24 pulls up and pushes down the workpiece outer ball joint with a certain pressure. As the workpiece outer ball joint moves under the pull and push of the rotary locking head 27, the rotary swing arm 30 swings under its own weight, and the detection probe 31 remains in contact with the ball head of the workpiece outer ball joint. During the swing of the rotary swing arm 30, the displacement sensor 32 detects the moving distance of the workpiece outer ball joint, thus achieving the purpose of detecting the axial clearance of the workpiece.

[0062] A balancing device 7 is provided on one side of the axial clearance detector 6 (see instruction manual appendix). Figure 1 and 2 The leveling device 7 includes a longitudinal gripper 42, a transverse gripper 39, a pusher cylinder 40, and a lifting cylinder 24.

[0063] On the frame 1 on one side of the indexing plate 2, a lead screw slide 37 is mounted via a motor and a control lead screw 36; a transverse gripper 39 is mounted on the lead screw slide 37 via a lifting cylinder 24; a clamping cylinder 41 is mounted on the frame 1 below the transverse gripper 39 via a pushing cylinder 40; longitudinal grippers 42 are symmetrically mounted on the clamping cylinder 41 (see the instruction manual appendix). Figure 10 ).

[0064] When the leveling device 7 is working, the indexing plate 2 moves the workpiece to the position corresponding to the leveling device 7 via the workpiece support 3. The control screw 36 first moves the lifting cylinder 24 and the transverse gripper 39 above the workpiece via the screw slide 37. Then, the lifting cylinder 24 moves the transverse gripper 39 downwards, causing it to clamp the upper end of the outer ball joint of the workpiece in the transverse direction. Subsequently, the control screw 36 moves the screw slide 37 back and forth in the transverse direction, ultimately moving the outer ball joint to the middle position in the transverse direction via the transverse gripper 39. After this process is completed, the transverse gripper 39 resets, and then the longitudinal gripper 42, in cooperation with the pushing cylinder 40 and the clamping cylinder 41, clamps the outer ball joint longitudinally, thus moving the outer ball joint of the workpiece to the middle position in the longitudinal direction. At this point, the leveling device 7 has completed its purpose of moving the outer ball joint of the workpiece to the middle position.

[0065] A grease injector 8 is provided on one side of the aligner 7 (see instruction manual appendix). Figure 1 and 2 The grease injector 8 includes grease tubes 45, a transverse slide plate 43, and a rotary cylinder 26; the transverse slide plate 43, which is mounted on the frame 1 on one side of the indexing plate 2, is connected to the indexing plate 2 by a cylinder; two sets of grease tubes 45 are symmetrically mounted on the transverse slide plate 43 via the rotary cylinder 26 (see the instruction manual appendix). Figure 11 ).

[0066] When the grease injector 8 is working, the grease injection tube 45 will move to the top of the workpiece with the help of the transverse sliding plate 43. Then, the rotating cylinder 26 drives the two sets of grease injection tubes 45 to rotate. During this process, the two sets of grease injection tubes 45 smoothly inject the grease into the workpiece base from both sides of the outer ball joint of the workpiece, thus completing the grease injection work.

[0067] The grease injector 8 has a small retaining ring dust cover assembler 9 on one side (see instruction manual appendix). Figure 1 and 2 The small clasp dust cover assembler 9 includes a small clasp vibrating feed plate 48, a dust cover vibrating feed plate 49, an assembly indexing plate 46, a gripping mechanism A50, a gripping mechanism B51, a gripping mechanism C52, a guide umbrella cover 55, and an extrusion cylinder 58 (see the instruction manual appendix). Figure 12 ).

[0068] The indexing plate 46 is mounted on the frame 1 on one side of the assembly indexing plate 2 (see the instruction manual appendix). Figure 12 and 34 The composite indexing plate 46 is equipped with multiple positioning cone seats 47 (see the instruction manual appendix). Figure 13 and 14 The external shape of the positioning cone 47 is consistent with the internal structure of the workpiece dust cover, and the dust cover can be placed on the positioning cone 47.

[0069] On one side of the indexing plate 46, the frame 1 is equipped with a small chuck vibrating feed plate 48 and a dust cover vibrating feed plate 49; a gripping mechanism A50 is installed on one side of the small chuck vibrating feed plate 48; a gripping mechanism B51 is installed on one side of the dust cover vibrating feed plate 49 (see the instruction manual appendix). Figure 12 and 34 The small chuck vibrating feeder 4 and the dust cover vibrating feeder 49 are purchased equipment. During operation, the small chuck vibrating feeder 4 can output the small chucks of the workpiece in a uniform posture, and the dust cover vibrating feeder 49 can output the dust cover of the workpiece in a uniform posture. When the gripping mechanism A50 is working, it can grip the small chucks of the workpiece from the small chuck vibrating feeder 48. When the gripping mechanism B51 is working, it can grip the dust cover of the workpiece from the dust cover vibrating feeder 49.

[0070] A gripping mechanism C52 is mounted on the frame 1 between the composite indexing plate 46 and the assembly indexing plate 2 (see the instruction manual appendix). Figure 12 and 34 The guide umbrella sleeve 55 is mounted above the indexing plate 46 between the small ring vibrating feed plate 48 and the dust cover vibrating feed plate 49 via the lifting cylinder 24 and the clamping cylinder 54 (see the instruction manual appendix). Figure 14 An extrusion cylinder 58 is mounted above the guide umbrella sleeve 55 via a transverse cylinder 19 and a pressing cylinder 57. Multiple expansion joints are evenly distributed on the surfaces of both the extrusion cylinder 58 and the guide umbrella sleeve 55 (see the attached instruction manual). Figure 15 ).

[0071] When the small clasp dust cover assembler 9 is working, the gripping mechanism B51 first grabs the dust cover from the vibrating dust cover feeding plate 49 and places it on the positioning cone seat 47 of the assembly indexing plate 46. Then, the assembly indexing plate 46 rotates one position, and the guide umbrella sleeve 55, with the cooperation of the lifting cylinder 24 and the clamping cylinder 54, is inserted into the dust cover. Next, the gripping mechanism A50 grabs the small clasp from the vibrating small clasp feeding plate 48 and sets it onto the guide umbrella sleeve 55. After these actions are completed, the extrusion cylinder 58, with the cooperation of the transverse cylinder 19 and the pressing cylinder 57, moves downward from above the guide umbrella sleeve 55, thus pushing the small clasp downward along the surface of the guide umbrella sleeve 55. As the small clasp moves downward along the surface of the guide umbrella sleeve 55, the clamping cylinder 54 releases the guide umbrella sleeve 55, thus preventing the clamping cylinder 54 from obstructing the movement of the small clasp. When the small retaining ring moves to the lower end of the guide umbrella sleeve 55, it will retract and snap onto the dust cover after losing the support of the guide umbrella sleeve 55. This completes the assembly of the small retaining ring and the dust cover. After the above work is completed, the guide umbrella sleeve 55 is reset under the action of the lifting cylinder 24 and the clamping cylinder 54, and the extrusion cylinder 58 is reset under the action of the transverse cylinder 19 and the pressing cylinder 57.

[0072] The dust cover assembler 9 for the small clasp is equipped with a dust cover assembler 10 on one side (see instruction manual). Figure 1 and 2 The dust cover assembler 10 includes a bracket 59, a lifting slide 25, a drive turntable 65, a clamping assembly 64, a dispersing slider 63, and a transmission roller 68 (see the attached instruction manual). Figure 16 ).

[0073] A lifting slide 25 is mounted on the frame 1 on one side of the indexing plate 2 via a bracket 59 and a lifting cylinder 24. A dispersing slider 63 is slidably mounted on the lifting slide 25 via a radiating slide groove 62 (see instruction manual appendix). Figure 18 The lower end of the dispersing slider 63 is equipped with a clamping assembly 64; a drive turntable 65 is mounted on the lifting slide 25 above the dispersing slider 63; a drive gear 66 is mounted on the lifting slide 25 on one side of the drive turntable 65 via a motor; the drive gear 66 meshes with the drive turntable 65; multiple arc-shaped drive grooves 67 are evenly distributed on the drive turntable 65 (see the appendix of the instruction manual). Figure 17 The arc-shaped drive groove 67 is connected to the corresponding dispersing slider 63 via the transmission roller 68.

[0074] The purpose of setting up the dispersing slider 63 and the drive turntable 65 in this way is to enable the drive turntable 65 to drive the dispersing slider 63 to slide back and forth along the slide groove 62 through the transmission roller 68 and the arc-shaped drive groove 67 during operation. In this way, the purpose of controlling the dispersing sliders 63 to move closer to each other or disperse can be achieved by the drive turntable 65.

[0075] The clamping assembly 64 includes a lower hook plate 69, an upper pressure plate 71, and a push cylinder 40; the lower end of the dispersing slider 63 is fixedly mounted with the lower hook plate 69; the upper pressure plate 71 is obliquely mounted on the dispersing slider 63 on one side of the lower hook plate 69 via the push cylinder 40; the upper pressure plate 71 passes through the lower hook plate 69 and extends to one side (see the appendix of the instruction manual). Figure 19 ).

[0076] When the dust cover assembler 10 is working, the lifting cylinder 24 first drives the lifting slide 25 to move down, so that each clamping component 64 is located around the dust cover; then the drive turntable 65 can drive the dispersing slider 63 to slide along the slide groove 62 through the transmission roller 68 and the arc-shaped drive groove 67, so that the dispersing slider 63 drives each clamping component 64 to move closer to each other, and finally so that one end of the lower hook plate 69 is located at the lower end of the dust cover. Then the push cylinder 40 pushes the upper pressure plate 71 to move closer to the lower hook plate 69, so that the upper pressure plate 71, with the cooperation of the lower hook plate 69, clamps and fixes the lower end of the dust cover.

[0077] After the lower end of the dust cover is clamped and fixed by the upper pressure plate 71 and the lower hook plate 69, the clamping components 64 separate from each other when the drive turntable 65 is activated. During the separation of the clamping components 64, the lower end of the dust cover is pulled and enlarged. Then, the lifting cylinder 24 drives the lifting slide 25 to move downward, allowing the enlarged dust cover to move along the outer surface of the workpiece's outer ball joint to a suitable installation position. Then, the upper pressure plate 71 of the clamping components 64 resets and releases the dust cover. At this time, the dust cover will be clamped to the workpiece's outer ball joint under its own elastic force, thus completing the assembly of the dust cover. Afterward, all components of the dust cover assembler 10 are reset.

[0078] A large retaining ring assembler 11 is provided on one side of the dust cover assembler 10 (see the instruction manual appendix). Figure 1 and 2 The large circlip assembler 11 includes a large circlip vibrating feed plate 72, a circlip feeding claw 74, a large circlip phase finding component 73, a gripping mechanism D75, an extrusion cylinder 58, and a guide umbrella sleeve 55 (see the instruction manual appendix). Figure 21 and 22 ).

[0079] A large retaining ring vibrating feed plate 72 is mounted on the frame 1 on one side of the indexing plate 2; a large retaining ring phase finding component 73 is mounted on one side of the large retaining ring vibrating feed plate 72 (see instruction manual appendix). Figure 21 and 22 ).

[0080] The large chuck phase finding assembly 73 includes an inner jaw chuck 76, a positioning slide head 79, an upper limit plate 81, and a displacement sensor 32 (see the instruction manual appendix). Figure 23 ).

[0081] One end of the large chuck phase finding assembly 73 is equipped with an inner jaw chuck 76 via a bracket 59 (see instruction manual appendix). Figure 24 The inner jaw chuck 76 is an externally purchased device. When the large chuck ring is placed on the inner jaw chuck 76, the jaws on the inner jaw chuck 76 can open to lock the large chuck ring and drive it to rotate together.

[0082] An upper limit plate 81 is symmetrically mounted on the sliding seat 78 via a clamping cylinder 41; the upper limit plate 81 is located above the inner jaw chuck 76; one end of the upper limit plate 81 is provided with a clearance slot 82. During operation, the upper limit plate 81 can restrict the large retaining ring to the jaws on the inner jaw chuck 76 from above, thus preventing the large retaining ring from deviating from the assembly position.

[0083] A sliding seat 78 is mounted on a bracket 59 on one side of the inner jaw chuck 76 via a pusher cylinder 40; a positioning slide head 79 is slidably mounted on the sliding seat 78 via a buffer spring 60 and a guide rod; a displacement sensor 32 is installed between one side of the positioning slide head 79 and the sliding seat 78 (see the instruction manual appendix). Figure 24 During operation, the sliding seat 78 can drive the positioning slide head 79 to contact the upper end of the large retaining ring. When the joint position of the rotating large retaining ring contacts the positioning slide head 79, the positioning slide head 79 will be displaced under the action of the buffer spring 60. At this time, the displacement sensor 32 will sense the displacement of the positioning slide head 79. The large retaining ring will then stop rotating, thus allowing the installation position of the large retaining ring, i.e., the phase of the large retaining ring, to be determined.

[0084] The large chuck phase finding component 73 has a chuck loading claw 74 mounted on one side via a transverse cylinder 19 and a lifting cylinder 24; the other side of the large chuck phase finding component 73 is equipped with a gripping mechanism D75 (see the instruction manual appendix). Figure 22 The circlip loading claw 74, in cooperation with the transverse cylinder 19 and the lifting cylinder 24, transfers the large circlip from the large circlip vibrating loading plate 72 to the large circlip phase finding component 73. The gripping mechanism D75 transfers the large circlip with the found phase from the large circlip phase finding component 73 to the guide umbrella sleeve 55.

[0085] One end of the large ring phase finding assembly 73 is equipped with a guide umbrella sleeve 55 via a lifting cylinder 24 and a clamping cylinder 54; above the guide umbrella sleeve 55, a pressing cylinder 58 is installed via a lifting cylinder 24 and a pressing cylinder 57 (see instruction manual appendix). Figure 25 During operation, the large retaining ring can be installed at the lower end of the dust cover in cooperation with the guide umbrella sleeve 55 and the extrusion cylinder 58.

[0086] An airtightness detector 12 is installed on one side of the large ferrule assembler 11 (see instruction manual appendix). Figure 1 and 2 The airtightness detector 12 includes an airtight pressure sleeve 70 and a detection plate 77 (see the instruction manual appendix). Figure 26 and 27 ).

[0087] A lifting slide 25 is mounted on the frame 1 on one side of the indexing plate 2 via a lifting cylinder 24; an airtight pressure sleeve 70 is fixedly installed in the center of the lifting slide 25; detection plates 77 are mounted on the lifting slides 25 on both sides of the airtight pressure sleeve 70 via cylinders and displacement sensors 32 (see the instruction manual appendix). Figure 26 and 29 During operation, the detection plate 77, in conjunction with the cylinder and displacement sensor 32, clamps towards the installation position of the large retaining ring. If the displacement distance of the detection plate 77 is too large, it indicates that the large retaining ring is not assembled, and the product is a defective product.

[0088] The bottom of the airtight pressure sleeve 70 is provided with a sealing cone hole 80; an air inlet 44 is installed on the airtight pressure sleeve 70 above the sealing cone hole 80 (see the instruction manual appendix). Figure 28 ).

[0089] A cone-shaped return device 13 is provided on one side of the airtightness detector 12 (see the instruction manual appendix). Figure 1 and 2 The cone sleeve returner 13 includes a gripping head 61, a transverse cylinder 19, and a lifting cylinder 24 (see the instruction manual appendix). Figure 30 and 31 ).

[0090] A clamping head 61 is mounted on the frame 1 on one side of the indexing plate 2 via a transverse cylinder 19 and a lifting cylinder 24; the clamping head 61 includes a pressing plate 38 and a clamping cylinder 53; the bottom end of the lifting cylinder 24 is fixedly mounted with the pressing plate 38 via symmetrical vertical plates 83; the clamping cylinder 53 is mounted on the lifting cylinder 24 above the pressing plate 38; the pressing plate 38 is provided with a clearance through hole 56 (see the attached instruction manual). Figure 31 ).

[0091] When the assembly device for the dust cover of the outer ball joint of the automotive steering gear is in operation, the axial clearance detector 6 operates first. When the axial clearance detector 6 operates, the workpiece must first be placed on the detection support 18 of the detection indexing plate 16. When the detection indexing plate 16 moves the workpiece via the detection support 18 to a position corresponding to the transverse slide 20, the transverse cylinder 19 moves the transverse slide 20 a certain distance, positioning the detection support 18 and the workpiece between the support column 29 and the detection clamp 21.

[0092] After the above work is completed, the lifting cylinder 28 presses the detection support 18 and the workpiece upward through the support column 29, so that the outer ball joint of the workpiece is finally clamped and fixed with the cooperation of the workpiece slot 22 of the detection clamp 21 (see the instruction manual appendix). Figure 9 Then, the control plate 34 moves upward, causing the rotating swing arm 30 to swing towards the workpiece, and finally bringing the detection probe 31 into contact with the ball head of the outer ball joint of the workpiece (see the instruction manual appendix). Figure 9 ).

[0093] After the detection probe 31 contacts the ball head of the outer ball joint of the workpiece, the lifting cylinder 24 drives the rotating cylinder 26 and the rotating locking head 27 to move down through the lifting slide 25; during the downward movement of the rotating locking head 27, the rotating cylinder 26 drives it to rotate, so that the rotating locking head 27 can maintain a threaded connection with the upper end of the outer ball joint of the workpiece.

[0094] After the rotary locking head 27 is threadedly connected to the upper end of the workpiece outer ball joint, the lifting cylinder 24 pulls up and pushes down the workpiece outer ball joint with a certain pressure. As the workpiece outer ball joint moves under the pull and push of the rotary locking head 27, the rotary swing arm 30 swings under its own weight, and the detection probe 31 remains in contact with the ball head of the workpiece outer ball joint. During the swing of the rotary swing arm 30, the displacement sensor 32 detects the moving distance of the workpiece outer ball joint, thus achieving the purpose of detecting the axial clearance of the workpiece.

[0095] After the axial clearance detector 6 completes the axial clearance detection, the rotating locking head 27, support column 29, and transverse slide 20 are reset in sequence. Then, the robot arm transfers the workpiece with qualified axial clearance to the corresponding workpiece support seat 3 on the assembly indexing plate 2. Then, the tapered sleeve robot arm 35 puts the detection tapered sleeve 5 into place above the outer ball joint of the automobile steering gear through the positioning tapered hole 14.

[0096] After the tapered sleeve robot 35 places the inspection tapered sleeve 5 above the outer ball joint of the automobile steering gear and resets, the assembly indexing plate 2 rotates one station to move the workpiece with the inspection tapered sleeve 5 to correspond with the straightener 7.

[0097] When the indexing plate 2 moves the workpiece to correspond with the leveling device 7 via the workpiece support 3, the control screw 36 first moves the lifting cylinder 24 and the transverse gripper 39 above the workpiece via the screw slide 37. Then, the lifting cylinder 24 moves the transverse gripper 39 downward, causing the transverse gripper 39 to clamp the upper end of the outer ball joint of the workpiece in the transverse direction. Subsequently, the control screw 36 moves the screw slide 37 back and forth in the transverse direction, ultimately moving the outer ball joint to the middle position in the transverse direction via the transverse gripper 39. After the above work is completed, the transverse gripper 39 resets, and then the longitudinal gripper 42 clamps the outer ball joint in the longitudinal direction with the cooperation of the pushing cylinder 40 and the clamping cylinder 41, thus moving the outer ball joint of the workpiece to the middle position in the longitudinal direction.

[0098] At this point, the leveling device 7 has completed its purpose of moving the outer ball joint of the workpiece to the middle position. Subsequently, all components of the leveling device 7 are reset, and the assembly indexing plate 2 rotates one station, so that the leveled workpiece rotates to correspond with the grease injector 8.

[0099] When the workpiece rotates to correspond with the grease injector 8, the grease injection tube 45 will move above the workpiece with the help of the transverse sliding plate 43. Then, as the rotary cylinder 26 drives the two sets of grease injection tubes 45 to rotate, the two sets of grease injection tubes 45 smoothly inject grease into the workpiece base from both sides of the outer ball joint of the workpiece, thus completing the grease injection work. Afterwards, the grease injection tubes 45 are reset, and the assembly indexing plate 2 rotates one position, so that the greased workpiece rotates to correspond with the small retaining ring dust cover assembler 9.

[0100] Subsequently, the small clasp dust cover assembler 9 operates. When the assembler 9 is working, the gripping mechanism B51 first grabs the dust cover from the vibrating feed plate 49 and places it onto the positioning cone 47 of the assembly indexing plate 46. Then, the assembly indexing plate 46 rotates one position, and the guide umbrella sleeve 55, with the cooperation of the lifting cylinder 24 and the clamping cylinder 54, is inserted onto the dust cover. Next, the gripping mechanism A50 grabs the small clasp from the vibrating feed plate 48 and sets it onto the guide umbrella sleeve 55. After these actions are completed, the extrusion cylinder 58, with the cooperation of the transverse cylinder 19 and the pressing cylinder 57, moves downwards from above the guide umbrella sleeve 55. Thus, the extrusion cylinder 58 pushes the small clasp downwards along the surface of the guide umbrella sleeve 55. As the small clasp moves downwards along the surface of the guide umbrella sleeve 55, the clamping cylinder 54 releases the guide umbrella sleeve 55, thus preventing the clamping cylinder 54 from obstructing the movement of the small clasp. When the small retaining ring moves to the lower end of the guide umbrella sleeve 55, it will retract and snap onto the dust cover after losing the support of the guide umbrella sleeve 55. This completes the assembly of the small retaining ring and the dust cover. After the above work is completed, the guide umbrella sleeve 55 is reset under the action of the lifting cylinder 24 and the clamping cylinder 54, and the extrusion cylinder 58 is reset under the action of the transverse cylinder 19 and the pressing cylinder 57.

[0101] After the small retaining ring dust cover assembler 9 installs the small retaining ring on the dust cover, the assembly indexing plate 46 rotates one station, and the gripping mechanism C52 grips the dust cover with the small retaining ring installed from the assembly indexing plate 46 and sets it on the outer ball joint of the workpiece on the assembly indexing plate 2 before resetting.

[0102] Then, the indexing plate 2 rotates one station so that the workpiece with the dust cover is aligned with the dust cover assembler 10. The dust cover assembler 10 then operates.

[0103] When the dust cover assembler 10 is working, the lifting cylinder 24 first drives the lifting slide 25 to move down, so that each clamping component 64 is located around the dust cover; then the drive turntable 65 can drive the dispersing slider 63 to slide along the slide groove 62 through the transmission roller 68 and the arc-shaped drive groove 67, so that the dispersing slider 63 drives each clamping component 64 to move closer to each other, and finally so that one end of the lower hook plate 69 is located at the lower end of the dust cover. Then the push cylinder 40 pushes the upper pressure plate 71 to move closer to the lower hook plate 69, so that the upper pressure plate 71, with the cooperation of the lower hook plate 69, clamps and fixes the lower end of the dust cover.

[0104] After the lower end of the dust cover is clamped and fixed by the upper pressure plate 71 and the lower hook plate 69, the clamping components 64 separate from each other when the drive turntable 65 is activated. During the separation of the clamping components 64, the lower end of the dust cover is pulled and enlarged. Then, the lifting cylinder 24 drives the lifting slide 25 to move downward, allowing the enlarged dust cover to move along the outer surface of the workpiece's outer ball joint to a suitable installation position. Then, the upper pressure plate 71 of the clamping components 64 resets and releases the dust cover. At this time, the dust cover will be clamped to the workpiece's outer ball joint under its own elastic force, thus completing the assembly of the dust cover. Afterward, all components of the dust cover assembler 10 are reset.

[0105] After the above work is completed, the assembly indexing plate 2 rotates one station so that the workpiece with the dust cover assembled is rotated to correspond with the large retaining ring assembler 11.

[0106] Subsequently, the large chuck assembler 11 operates. First, the guide umbrella sleeve 55 is fitted onto the workpiece with the cooperation of the lifting cylinder 24 and the clamping cylinder 54. Then, the chuck loading claw 74, with the cooperation of the transverse cylinder 19 and the lifting cylinder 24, transfers the large chuck from the large chuck vibrating loading plate 72 to the inner jaw chuck 76 of the large chuck phase finding component 73.

[0107] Subsequently, with the cooperation of the sliding seat 78 and the clamping cylinder 41, the upper limit plate 81 of the large retaining ring phase-finding assembly 73 closes, which from above restricts the large retaining ring onto the jaws of the inner jaw chuck 76. At this time, the positioning slide head 79 will maintain contact with the upper end of the large retaining ring under the action of the buffer spring 60. Then, the inner jaw chuck 76 will drive the large retaining ring to rotate at a constant speed. During the constant speed rotation of the large retaining ring, when the joint position of the large retaining ring rotates to contact the positioning slide head 79, the positioning slide head 79 will be displaced. At this time, the displacement sensor 32 will sense the displacement of the positioning slide head 79. Then, the inner jaw chuck 76 stops rotating, and then the upper limit plate 81 and the positioning slide head 79 reset.

[0108] The gripping mechanism D75 grips the large retaining ring that has completed phase finding from the inner jaw chuck 76 and fits it onto the guide umbrella sleeve 55. Subsequently, the lifting cylinder 24 and the pressing cylinder 57 press the large retaining ring along the surface of the guide umbrella sleeve 55 through the extrusion cylinder 58, causing it to move to the lower end of the guide umbrella sleeve 55 and then retract and clamp onto the dust cover under its own elastic force, thus completing the assembly of the large retaining ring. Afterwards, the large retaining ring assembler 11 resets, and the assembly indexing plate 2 rotates one station to transfer the workpiece with the completed large retaining ring assembly to the position corresponding to the airtightness detector 12.

[0109] Subsequently, the airtightness detector 12 operates. When the airtightness detector 12 operates, the lifting cylinder 24 first moves the lifting slide 25 downwards, causing the airtight pressure sleeve 70 to press against the detection cone sleeve 5 on the workpiece. Then, the detection clamping plate 77, with the cooperation of the cylinder and displacement sensor 32, clamps towards the installation position of the large retaining ring. If the displacement distance of the detection clamping plate 77 is too large, it indicates that the large retaining ring is not installed, and the product is unqualified; otherwise, it is qualified. Simultaneously, external air supply equipment pressurizes the dust cover through the vent holes 15 on the airtight pressure sleeve 70 and the detection cone sleeve 5. During this process, the airtightness of the dust cover can be determined by the change in air pressure, thus achieving the purpose of detecting whether the dust cover installation is qualified. The airtightness detector 12 resets after completing the test.

[0110] The assembly indexing plate 2 rotates one station to transfer the workpiece to be inspected to correspond with the cone sleeve returner 13. Then, the gripping head 61, in cooperation with the transverse cylinder 19 and the lifting cylinder 24, squeezes the dust cover through the pressing plate 38, disengaging it from the inspection cone sleeve 5. The gripping cylinder 53 then grips the inspection cone sleeve 5, and subsequently, with the cooperation of the transverse cylinder 19 and the lifting cylinder 24, the gripping cylinder 53 repositions the inspection cone sleeve 5 onto the support rod 4. At this point, the assembly device for the outer ball joint dust cover of the automotive steering gear has completed the assembly and inspection work. After the assembled workpiece is removed from the assembly indexing plate 2, the assembly device can proceed to the next work cycle.

[0111] The assembly device for the dust cover of the outer ball joint of the automobile steering gear is compact and ingeniously designed. It can continuously and mechanically complete the assembly of the dust cover of the outer ball joint of the automobile steering gear, thereby solving the problem of low work efficiency in the existing assembly of dust covers of the outer ball joint of the automobile steering gear. It is particularly suitable for the needs of assembling dust covers of the outer ball joint of the automobile steering gear.
