[0013] Preferably, it also includes a second rivet oiling assembly, and the external oil supply module further includes an oil outlet pipe four.

[0014] Preferably, the positioning fixture includes positioning fixture one and positioning fixture two. Positioning fixture one is provided with a shell inner wall contouring limiting module, a shell outer wall contouring limiting module, a shell outer wall and limiting arm contouring limiting module one and a shell outer wall and limiting arm contouring limiting module two. The outer wall of the housing and the contouring and limiting module one is used to limit the placement of the housing one as a whole with the limiting arm inserted, and the outer wall of the housing and the contouring and limiting module two is used to limit the placement of the limiting arm as a whole with the housing one and housing two assembled.

The hollow rivet feeding mechanism, housing oiling mechanism, spring and slider feeding mechanism, elasticity testing and oiling mechanism, dustproof pad assembly mechanism, housing assembly mechanism, rivet flanging mechanism, flanging detection and unloading mechanism, limit arm oiling assembly, and riveting mechanism are distributed along the turntable.

[0015] The beneficial effects of this invention are as follows: This solution, by setting up positioning fixtures, a hollow rivet feeding mechanism, an external oil supply module, a housing oiling mechanism, a spring and slider feeding mechanism, an elasticity testing and oiling mechanism, a dustproof pad assembly mechanism, a housing assembly mechanism, a rivet flanging mechanism, a flanging detection and unloading mechanism, a limit arm oiling assembly, a pre-assembly station, and a riveting mechanism, and distributing these mechanisms along a turntable, achieves fully automated operation from feeding housing one, housing two, dustproof pad, limit arm, spring, slider, bracket, and rivets one and two, to housing oiling, spring and slider assembly, elasticity testing, dustproof pad assembly, housing assembly, rivet flanging, flanging detection, limit arm oiling, bracket pre-assembly, riveting, and assembly inspection. This equipment effectively solves the problems of low automation, dispersed processes, significant safety hazards in oiling operations, and incomplete inspection in existing technologies, greatly improving the assembly efficiency and product qualification rate of the door limit arm, and reducing labor costs and labor intensity.

[0016] The design incorporates a hollow positioning head, consisting of an open fixing section and several interlocking pieces. This hollow positioning head is positioned so that the opening near the housing is constricted, preventing the rivet from accidentally falling off during transport. Simultaneously, an opening and closing unit controls the opening and / or closing of the constricted opening of the interlocking pieces, ensuring stable positioning of the rivet during loading and before insertion, while also allowing the constricted opening to smoothly open and allow the rivet to enter the rivet hole in the housing. This simple and reliable structure improves the stability and accuracy of rivet loading.

[0017] The spring-cutting assembly and the slider-cutting assembly enable the individual separation and orderly feeding of springs and sliders, avoiding material stacking or jamming. The slider rotation positioning assembly, with the cooperation of slider positioning fixture, rotation drive assembly and slider position detection module, can accurately position and correct the circumferential angle of the slider before it moves, ensuring that the orientation of its locking spring arm is consistent with the internal installation position of the housing when the slider moves into the housing. This avoids assembly defects caused by slider angle deviation and improves assembly accuracy and yield.

[0018] By installing an oil inlet connecting block with an oil inlet channel at the working end of the elasticity testing press, and connecting the outlet pipe two to this oil inlet channel, the elasticity testing press can simultaneously deliver lubricating oil through the oil inlet channel to the area to be oiled on the slider through the movement of the same working end while performing the elasticity test. This achieves one-stop synchronous completion of elasticity testing and oiling operations. This structure simplifies equipment layout, reduces process changeover time, and improves production efficiency.

[0019] In this design, the two plugs of the shift fork in the torque testing assembly are inserted into both sides of the bracket, with the distance between the two plugs greater than the width of the bracket. This ensures that regardless of the angle of the bracket between the two limit blocks, the two plugs can be smoothly inserted into both sides of the bracket without interference, thus avoiding the problem of plugs being unable to be inserted or getting stuck due to bracket position deviation. At the same time, through the cooperation of the torque testing motor and torque sensor, online automatic detection of the bracket's rotation torque is achieved, which can promptly detect and reject products with unqualified torque, ensuring the stability of product quality.

[0020] In this system, by setting up an oiling assembly for rivet two, the oiling cylinder drives the oil outlet of oil pipe four to move to rivet two for oiling. In conjunction with the oiling motor, the oiling head is driven to spread the lubricating oil evenly on the end face of rivet two, so that the lubricating oil on both ends of rivet two is evenly distributed and of uniform thickness. This effectively prevents problems such as poor lubrication or oil contamination caused by local lack of oil or excessive oil, and further improves the rust prevention performance and assembly quality of the product.

The positioning fixture 7 includes a dustproof pad positioning post 701 and a limiting arm positioning module 703. The top of the dustproof pad positioning post 701 is provided with a dustproof pad positioning block 702, and the dustproof pad is sleeved on the dustproof pad positioning block 702. The limiting arm 01 is placed on the limiting arm positioning module 703. It also includes a fixed rotary table, on which a turntable 20 is driven, and the positioning fixture 22 is evenly distributed around the turntable 20. The fixed rotary table is a hollow rotating platform, which includes a reducer driven by a motor. The reducer drives the turntable 20 to rotate. There is a through hole in the center of the turntable 20 for a support frame to pass through. The top of the support frame passes through the through hole, and a fixed plate 21 is fixed on the support frame (this type of fixed rotary table is a standard existing equipment).

[0025] The hollow rivet feeding mechanism 1, the housing oiling mechanism 2, the spring and slider feeding mechanism 4, the elasticity testing and oiling mechanism 5, the dustproof pad assembly mechanism 6, the housing assembly mechanism 8, the rivet flanging mechanism 9, the flanging detection and unloading mechanism 10, the limit arm oiling assembly 11, and the riveting mechanism 14 are distributed along the turntable 20.

[0026] See Figure 30 Several clamping and fixing components 19 are fixedly installed on the fixed plate 21. The clamping and fixing components 19 include a clamping limit bracket 1901 fixed on the fixed plate 21 and a clamping limit cylinder 1902 installed on it. The working end of the clamping limit cylinder 1902 is provided with a contouring pressure head 1903. The function of the clamping and fixing assembly 19 is to clamp the corresponding workpiece onto its tooling during each process. Its setting positions include clamping position four 2204 before the assembly press 1402 operates (hereinafter, it refers to clamping the workpiece inside it), clamping position four 2204 before the riveting press 1406 operates, clamping position four 2204 before the torque test moving cylinder 1502 operates, clamping position two 2202 before the housing assembly linear module 802 operates, and clamping position four 2204 before the oiling moving assembly three 1102 operates (the clamping limit bracket 1901 and the third oiling bracket 1101 share one at this position).

[0027] See Figures 4 to 6The rivet feeding assembly includes a rivet feeding vibratory feeder 101, a feeding pipe 102, and a hollow positioning head 103 with openings at both ends. The rivet feeding vibratory feeder 101 is a conventional air-blowing vibratory feeder, which enables T-shaped hollow rivets (i.e., rivets 08) to be arranged in an orderly manner along its built-in spiral track and conveyed to the discharge port. The material at the discharge port is blown out from the feeding pipe 102 by an air-blowing feeding system. One end of the feeding pipe 102 is connected to the discharge port of the rivet feeding vibratory feeder 101, and the other end is connected to the hollow positioning head 103, thereby realizing remote feeding of rivets 08.

[0028] The hollow positioning head 103 is vertically arranged, and its internal channel has a Y-shaped cross-section, specifically including three openings: the two upper openings are used to connect the feeding pipe 102 and the rivet push rod 106 to enter, respectively, while the lower opening is used to push the rivet 08 onto the housing 04. The hollow positioning head 103 includes an opening fixing section 107 and an opening changing section. The opening changing section is located near the end of the housing 04 and is composed of several splicing pieces 108 hinged to the opening fixing section 107. In this embodiment, two splicing pieces 108 are provided, and the outer walls of the two splicing pieces 108 are provided with a limiting groove that is integrally spliced ​​into an annular shape. A rubber band 109 is installed in the limiting groove. The contraction elasticity of the rubber band 109 causes the two splicing pieces 108 to splice together, thereby making the opening of the hollow positioning head 103 near the housing 04 narrow, to prevent the rivet 08 from accidentally dislodging under gravity or airflow. The rivet-1 pushing assembly includes a rivet feeding frame 104 and a rivet pushing cylinder 105 mounted on the rivet feeding frame 104. The output end of the rivet pushing cylinder 105 is connected to a rivet push rod 106. The rivet push rod 106 can enter the hollow positioning head 103 from the Y-shaped right-side opening above the hollow positioning head 103 and push the rivet-1 08 located in the hollow positioning head 103 out from the lower opening.

[0029] In addition, a rivet receiving pin 110 and a rivet receiving cylinder 111 that controls their up-and-down movement are also installed below the rivet feeding frame 104. Before the rivet pushing cylinder 105 operates, the rivet receiving cylinder 111 is controlled to drive the rivet receiving pin 110 upward, so that it is inserted into the inner hole of the rivet 08 located in the hollow positioning head 103 for guidance and limitation. Subsequently, the rivet pushing cylinder 105 and the rivet receiving cylinder 111 work synchronously. The rivet push rod 106 pushes the rivet 08 downward, and at the same time, the rivet receiving pin 110 moves downward, together pushing the rivet 08 smoothly and accurately into the rivet hole on the housing 04.

[0030] To prevent interference between the material on the positioning fixture 22 and the hollow positioning head 103 during the movement of the turntable 20, a clearance lifting cylinder 112 is also installed on the rivet feeding frame 104. A connecting slide 113 is installed at the output end of the clearance lifting cylinder 112, and the rivet pushing cylinder 105 is mounted on the connecting slide 113. Through the extension and retraction of the clearance lifting cylinder 112, the connecting slide 113, the rivet pushing cylinder 105, and the hollow positioning head 103 can be raised and lowered as a whole, allowing the hollow positioning head 103 to rise and avoid the positioning fixture 22 and its material on the turntable 20 when not in operation.

[0031] The working process of this part of the equipment is as follows: First, the rivet feeding vibratory plate 101 feeds T-shaped rivets 08 into the hollow positioning head 103 through the feeding pipe 102 by air blowing. The rubber band 109 keeps the splicing piece 108 in a constricted state to receive and position the rivet 08. Next, the rivet receiving cylinder 111 drives the rivet receiving pin 110 to rise and insert into the inner hole of the rivet 08. Subsequently, the clearance lifting cylinder 112 drives the connecting slide 113 to descend, so that the lower opening of the hollow positioning head 103 is aligned with the rivet hole of the housing 04 on the positioning fixture 22. Then, the rivet pushing cylinder 105 pushes the rivet push rod 106 downward, which in turn pushes the rivet 08, causing the lower end of the rivet 08 to open the two splicing pieces 108. At the same time, the rivet receiving pin 110 and the rivet push rod 106 move downward in sync, precisely pushing the rivet 08 into and pre-installing it in the rivet hole of the housing 04. After the insertion is completed, the rivet pushing cylinder 105 and the rivet receiving cylinder 111 reset, and the avoidance lifting cylinder 112 drives the hollow positioning head 103 to rise and reset, waiting for the next feeding action.

[0032] See Figures 7 to 10 The shell oiling mechanism 2 is used to oil the inner walls of shell 1 04 and shell 2 05. The mechanism includes an oiling bracket 1 201, on which are mounted an oiling flipping motor 204, an oiling flipping lifting cylinder 208, an oiling fixing lifting cylinder 209, an oiling fixing cylinder 1 202, and an oiling moving assembly 1.

[0033] An oiling and tilting motor 204 is fixedly mounted on the output end of an oiling and tilting lifting cylinder 208, which is vertically mounted on an oiling bracket 201 to drive the overall lifting and lowering of the oiling and tilting motor 204. An eccentric swing arm 205 is fixedly connected to the rotating end of the oiling and tilting motor 204. One end of the eccentric swing arm 205 is fixed to the output shaft of the oiling and tilting motor 204, and the other end is fitted with an oiling gripper cylinder 206. A baffle 207 is fixed to each of the two grippers of the oiling gripper cylinder 206. The two baffles 207 are positioned opposite each other and are used to block the head of the rivet 08 from above when the grippers are closed, preventing the rivet 08 from falling off during the tilting process. The oiling flipping motor 204 drives the oiling gripper cylinder 206 to swing in the vertical plane through the eccentric swing arm 205, thereby clamping and flipping the housing 04, which is in an inverted state on the inner wall contouring limiting module (position 1 2201), so that the opening of the housing 04 is placed on the outer wall contouring limiting module (position 3 2203) for subsequent oiling operations.

[0034] The lifting cylinder 209 for oiling and fixing is vertically mounted on the oiling bracket 201. An oiling fixing cylinder 202 is horizontally mounted on its output end, and an oiling fixing head 203 is mounted on the output end of the oiling fixing cylinder 202. The oiling fixing head 203 is used to press against the outer wall of housing 04 or housing 05 from the side during the oiling process, fixing it within the positioning fixture to prevent workpiece displacement during oiling. The lifting cylinder 209 for oiling and fixing is used to adjust the position and height of the oiling fixing cylinder 202 to avoid motion interference when the turntable 20 moves.

[0035] The first oiling moving assembly includes a first oiling moving assembly 210 mounted on an oiling bracket 201. The first oiling moving assembly 210 can be a linear module driven by a motor. An oiling slide 211 is mounted on the working end of the first oiling moving assembly, and an oiling horizontal moving cylinder 213 is mounted on the oiling slide 211. A second first oiling moving assembly 212 is mounted on the moving end of the oiling horizontal moving cylinder 213. The second first oiling moving assembly 212 consists of two cylinders arranged side-by-side (named oiling lifting cylinders). Each cylinder's output end is fixedly equipped with an oil outlet pipe 301 (the outlet of the first oil outlet pipe is divided into two pipes). That is, the first oil outlet pipe is actually divided into four independent pipes in this mechanism. Two pipes on one of the second first oiling moving assemblies 212 are used to transport black oil, and two pipes on another of the second first oiling moving assemblies 212 are used to transport grease, so as to achieve separate supply of different lubricating greases.

[0036] The overall working process of the housing oiling mechanism 2 is as follows: First, the oiling tilting lifting cylinder 208 drives the oiling tilting motor 204 to descend, and the two grippers of the oiling gripper cylinder 206 close; then, the oiling tilting lifting cylinder 208 rises, the oiling tilting motor 204 starts, and the housing 04 is tilted 180° by the eccentric swing arm 205, so that the opening of the housing 04 faces upward, and is placed on the outer wall of the housing and the contour limiting module 1 (position 2202) of the limiting arm with the cooperation of the oiling tilting lifting cylinder 208; next, the oiling fixing lifting cylinder 209 drives the oiling fixing cylinder 202 to move to a suitable height, and the oiling fixing cylinder 202 pushes the oiling fixing head 203 to press against the outer wall of the housing 04, and the housing 04 is tilted. The components are fixed within the positioning fixture. Then, the first oiling moving assembly moves the oiling slide 211 horizontally, causing the two outlets of the first oiling moving assembly 212 to extend into the interiors of housing 04 and housing 05 respectively for oiling. Next, the horizontal moving cylinder 213 drives the first oiling moving assembly 212 to move horizontally, causing the two outlets of the second oiling moving assembly 212 to extend into the interiors of housing 04 and housing 05 respectively for oiling. The external oil supply module 3 sprays black oil or grease onto the inner wall of the housing through the oil outlets. The grease can be black oil or a special grease containing extreme pressure anti-wear additives, or a general-purpose lithium-based grease for routine rust prevention and friction reduction lubrication of the moving parts of the equipment. After oiling is completed, each cylinder and module is reset sequentially, awaiting the next oiling operation.

[0037] See Figures 11-15 The spring and slider feeding mechanism 4 is used to automatically feed, assemble, and transfer the assembly of spring 07 and slider 06 into the housing. This mechanism mainly includes a spring feeding assembly, a slider feeding assembly, a slider rotation positioning assembly, a spring pressing assembly, and a slider transferring assembly.

[0038] The spring feeding assembly includes a spring feeding vibratory plate 401 and a spring cutting assembly. The spring feeding vibratory plate 401 is an air-blowing vibratory plate, which arranges the springs 07 in an orderly manner and conveys them to the spring cutting assembly through a second feeding pipe 417. The spring cutting assembly includes a spring cutting fixture 402 and a spring cutting cylinder 403. The outlet of the spring feeding vibratory plate 401 is connected to the limiting groove inside the spring cutting fixture 402 through the second feeding pipe 417. The extension and retraction of the spring cutting cylinder 403 controls the connection and separation between the spring cutting fixture 402 and the outlet of the second feeding pipe 417, thereby positioning a single spring 07 at the position to be picked up. The spring cutting cylinder 403 is fixedly installed on the spring fixture bracket 411.

[0039] The slider feeding assembly includes a slider feeding vibratory feeder 404 and a slider cutting assembly. The slider feeding vibratory feeder 404 arranges the sliders 06 in an orderly manner and conveys them to the slider cutting assembly. The slider cutting assembly includes a slider cutting fixture 405 and a slider cutting cylinder 406. The discharge port of the slider feeding vibratory feeder 404 is connected to the internal slide of the slider cutting fixture 405. The extension and retraction of the slider cutting fixture 405 controls the connection and separation between the discharge port of the slider feeding vibratory feeder 404 and the slider cutting fixture 405, thereby separating a single slider 06 from the feeding slide and positioning it at the pressing position. The slider cutting cylinder 406 is fixedly mounted on the slider fixture bracket 410.

[0040] The slider rotation positioning assembly includes a slider positioning fixture 407, a rotation drive assembly 408 for controlling the rotation of the slider positioning fixture 407, and a slider position detection module. The slider positioning fixture 407 is rotatably mounted on the rotation positioning bracket 412. Specifically, two synchronous pulleys are rotatably connected to the rotation positioning bracket 412, and the two synchronous pulleys are driven by a synchronous belt 419. Each synchronous pulley has a slider positioning fixture 407 fixed to its top, and the top of the slider positioning fixture 407 has a positioning groove adapted to the outer contour of the slider 06 (the bottom contour of the slider 06 is cylindrical). The rotation drive assembly 408 (motor) is mounted below the rotation positioning bracket 412, and its output end is fixedly connected to one of the synchronous pulleys. The slider position detection module is mounted on the rotary positioning bracket 412 and located next to the slider positioning fixture 407. It can be a photoelectric sensor used to detect whether the slider 06 has been placed in place and whether its circumferential angle is correct (the top of the slider 06 has a non-circular contour feature (such as a flat part, a boss or a notch), and this top contour has a fixed angular correspondence with the snap-fit ​​spring arm 061 inside the slider 06 in the circumferential direction. The photoelectric sensor determines whether the circumferential angle of the slider 06 is correct by detecting the position change of this top contour, thereby ensuring that when the slider 06 is clamped and moved into the housing, the position of the slider is consistent with its installation orientation on the housing).

[0041] Among them, the slider tooling bracket 410, the spring tooling bracket 411, and the rotary positioning bracket 412 are arranged at equal intervals along the horizontal direction.

[0042] The slider material transfer assembly includes a fixedly mounted slider horizontal movement linear module 413, a slider moving slide 414 slidably mounted on the output end of the slider horizontal movement linear module 413, a slider vertical movement cylinder 415 fixedly mounted on the slider moving slide 414, and a slider gripper cylinder 416 mounted on the output end of the slider vertical movement cylinder 415. The slider horizontal movement linear module 413 is a motor-driven lead screw guide rail module, which extends horizontally along the arrangement direction of the slider cutting fixture 405, the spring cutting fixture 402, and the rotary positioning bracket 412. The slider moving slide 414 is fixedly connected to the lead screw nut seat of the slider horizontal movement linear module 413 and can slide horizontally back and forth along the guide rail of the module. The vertical movement cylinder 415 for the slider is vertically fixed on the slider moving slide table 414. Its piston rod end is fixedly connected to the slider gripper cylinder 416 via a connecting plate. The slider gripper cylinder 416 is a parallel opening and closing type pneumatic gripper, with gripping fingers on its two grippers that match the shape of the slider 06, used to grip or release the slider 06. The slider transfer assembly is used to move the slider from the material-to-be-picked station to the pressing station, and simultaneously grip and move the slider 06 with the spring 07 assembled on it from the pressing station into the slider positioning fixture 407.

[0043] The spring pressing assembly is used to assemble the spring 07 into the snap-fit ​​arm 061 of the slider 06. In this embodiment, to achieve simultaneous assembly of housing 1 04 and housing 2 05, two sets of spring feeding assembly, slider cutting assembly, and related pressing components are provided. Specifically, two vertical slider movement cylinders 415 are arranged side by side on the slider movement slide 414. One of the vertical slider movement cylinders 415 has four slider gripper cylinders 416 on the first connecting plate 418 at its lower end, which are divided into two groups of two. One group corresponds to the positions of two slider cutting fixtures 405, and the other group corresponds to the positions of two spring cutting fixtures 402. The other vertical slider movement cylinder 415 has two slider gripper cylinders 416 on its lower connecting plate, corresponding to the positions of two slider positioning fixtures 407 respectively. The slider gripper cylinders 416 are used to clamp the slider 06 with the spring 07 assembled. During operation, the vertical movement of the slider is driven by the cylinder 415 to lower the spring gripper cylinder, pressing the clamped spring 07 into the slider 06. The slider 06 has a snap-fit ​​arm 061 inside, so that after the spring 07 is pressed in, the end of the snap-fit ​​arm 061 is engaged in the gap between the spiral coils of the spring 07, thereby preventing the spring 07 from detaching from the slider 06.

[0044] The working process of the equipment is as follows: the spring feeding vibratory plate 401 sends the spring 07 to the pressing position of the spring cutting fixture 402, while the slider feeding vibratory plate 404 sends the slider 06 to the material picking position of the slider cutting fixture 405.

[0045] Two vertical slider cylinders 415 simultaneously drive three sets of slider gripper cylinders 416 to descend simultaneously, picking up the slider cutting fixture 405, the spring cutting fixture 402 (assembled slider 06 and spring 07), and the slider positioning fixture 407 (adjusted slider 06) respectively. Then, the two vertical slider cylinders 415 rise, the spring cutting fixture 402 resets, and after spring 07 is loaded, it returns to the pressing position. Subsequently, the horizontal slider linear module 413 drives the three sets of slider gripper cylinders 416 to descend. (The last sentence appears to be incomplete and possibly refers to a specific mechanism or process.) Figure 12 At the aforementioned positions, the leftmost set of sliders is lifted by the gripper cylinder 416 to above the pressing station; the middle set of sliders is lifted by the gripper cylinder 416 to above the slider positioning fixture 407; and the rightmost slider is lifted by the gripper cylinder 416 to above the outer wall contouring limiting module (position three 2203) on the positioning fixture 22, and above the outer wall contouring limiting module 1 (position two 2202) containing housing 2 05 and housing 1 04. Then, they simultaneously descend, causing the housings to fall into their respective positions. The leftmost set of sliders is controlled by a gripper cylinder 416 to descend while simultaneously pressing slider 06 into spring 07. (A stop block can be installed above the gripper cylinder to achieve a clearance fit with the top of slider 06, so that if slippage occurs during the descent of the gripper cylinder, the stop block can press against the top of slider 06 to provide downward pressure.) Next, the two sliders move vertically upward using cylinder 415, and the slider horizontal movement linear module 413 resets. Simultaneously, the rotation drive assembly 408 adjusts the position of slider 06. By repeating the above actions, the position of slider 06 is moved after each loading.

[0046] See Figure 16 , Figure 17 The elasticity testing press 502 is mounted on an elasticity testing frame 501. An oil inlet connecting block with an oil inlet channel 504 is installed at the working end of the elasticity testing press 502. The outlet of the second oil pipe is connected to one end of the oil inlet channel 504 on the oil inlet connecting block, and the other end of the oil inlet channel 504 (i.e., the oil outlet 509) can move onto the slider 06 as the elasticity testing press 502 moves.

[0047] A pressure sensor 508 is installed at the working end of the elasticity testing press 502 to provide feedback on the elastic force of the spring 07. An oil inlet connection block is installed below the pressure sensor 508. The elasticity testing press 502 constitutes the second oiling moving assembly, and the movement of its working end moves the outlet of the second oil pipe. The oil inlet connection block includes a stepped hollow block 503 with an oil inlet channel installed below the pressure sensor 508 and an oiling limiting sleeve 505 fitted onto the stepped hollow block 503. An oiling limiting groove 506, vertically oriented, is formed on the stepped hollow block 503. An oiling limiting bolt 507 is threaded onto the oiling limiting sleeve 505, with one end of the bolt placed within the oiling limiting groove 506, allowing the oiling limiting sleeve 505 to slide on the stepped hollow block 503 without disengaging. Meanwhile, an oiling spring is provided between the stepped hollow block 503 and the oiling limiting sleeve 505 to provide elastic force for downward reset. The lower end of the oiling limiting sleeve 505 has a conformal structure that fits the top of the slider 06, so that the elasticity testing press 502 can guide and position the slider 06 during descent, avoiding the problem of unstable position caused by the influence of the spring 07 inside the slider 06. The oil inlet channel 504 is installed on the stepped hollow block 503 and communicates with the hollow channel inside. The outlet of the hollow channel of the stepped hollow block 503 is the oil outlet 509.

[0048] The overall working process of the elasticity testing and oiling mechanism 5 is as follows: When the positioning fixture, carrying the housing with the spring 07 and slider 06 assembled, moves to the elasticity testing and oiling station, the elasticity testing press 502 starts, and its working end drives the pressure sensor 508 and the oil inlet connecting block to move downward as a whole. The contoured structure at the lower end of the oiling limiting sleeve 505 first contacts the top of the slider 06, and as the elasticity testing press 502 continues to press down, the oiling limiting sleeve 505 slides upward relative to the stepped hollow block 503, and the oiling spring is compressed, thereby providing flexible guidance and positioning force to the slider 06, ensuring that the slider 06 is stable in position during testing and oiling. Subsequently, the working end of the elasticity testing press 502 continues to press down, and the pressure sensor 508 detects and feeds back the elasticity value corresponding to the amount of compression of the spring 07 in real time, thus completing the elasticity test. After the elasticity test is completed or during the test, the external oil supply module 3 is activated. Lubricating oil is delivered through the oil outlet pipe 2 to the oil inlet channel 504 inside the stepped hollow block 503, and finally flows out from the oil outlet 509, precisely coating the area to be coated on the top of the slider 06. After the oiling and testing are completed, the working end of the elasticity test press 502 rises and resets, and the oiling limit sleeve 505 returns to its initial extended position under the elastic force of the oiling spring, waiting for the next working cycle.

[0049] See Figure 18 , Figure 19The positioning fixture includes a dustproof pad positioning post 701, and a dustproof pad positioning block 702 is provided on the top of the dustproof pad positioning post 701. The dustproof pad is sleeved on the dustproof pad positioning block 702, and the edge of the dustproof pad extends radially beyond the outer edge of the top surface of the dustproof pad positioning post 701, so as to clamp the edge of the dustproof pad during subsequent flaring operations.

[0050] The dustproof mat flaring assembly includes a dustproof mat angle adjustment motor 603, a dustproof mat clamping cylinder 604 mounted on the output end of the dustproof mat angle adjustment motor 603, and two dustproof mat clamping cylinders 605 mounted on the two clamping ends of the dustproof mat clamping cylinder 604. These cylinders drive the dustproof mat clamping cylinder 604 to rotate in the horizontal plane to adjust the circumferential angle of the dustproof mat 09, aligning it with the insertion direction of the limiting arm 01. The dustproof mat angle adjustment motor 603 is mounted on the lifting end of a dustproof mat lifting cylinder 608, which is fixedly mounted on a dustproof mat mounting frame 602. The two dustproof mat clamping cylinders 605 are arranged opposite each other, and their respective clamping ends are used to clamp opposite edges of the dustproof mat 09.

[0051] Furthermore, multiple positioning fixtures 7 are provided, and these fixtures 7 are evenly distributed circumferentially on a disc 606. The disc 606 is horizontally positioned, and its center is fixedly connected to the output shaft of a fixture-use rotary motor 607. The fixture-use rotary motor 607 is supported on the ground by a separate frame and is used to drive the disc 606 to rotate intermittently around its vertical axis, thereby sequentially delivering each positioning fixture 7 to the working position of the dustproof pad flaring assembly.

[0052] The limiting arm moving assembly 601 is a six-axis robotic arm. The end effector of the six-axis robotic arm is equipped with a limiting arm gripping assembly 609. The limiting arm gripping assembly 609 is used to grip the limiting arm 01 from the limiting arm positioning module 703 on the positioning fixture 27. After the dust pad flaring assembly completes the flaring operation, one end of the limiting arm 01 is inserted into the opening of the dust pad 09. Then, the dust pad 09 with the limiting arm 01 is moved together and placed into the outer wall of the housing on the positioning fixture 22 and the housing 04 in the limiting arm contour limiting module 1 (position 2202).

[0053] In addition, a dustproof pad presence detection camera 610 is installed on a single independent frame to detect whether a dustproof pad exists on the positioning fixture 2 (by setting it, the limit arm can also be detected synchronously).

[0054] The overall working process of the dustproof mat assembly mechanism 6 is as follows: First, the second tooling uses a rotary motor 607 to drive the disc 606 to rotate, transporting the positioning tooling 7, on which the dustproof mat 09 is fitted, to the working position of the dustproof mat flaring assembly. The dustproof mat lifting cylinder 608 controls the dustproof mat angle adjustment motor 603 to lift and lower to a position where it can be clamped. After clamping, it rises. Then, according to the insertion angle requirement of the limit arm 01, the dustproof mat angle adjustment motor 603 drives the dustproof mat clamping cylinder 604 to rotate to a predetermined angle. Subsequently, the dustproof mat clamping cylinder 604 actuates, causing the two dustproof mat clamping cylinders 605 to actuate simultaneously. Their grippers open outward, widening the opening of the dustproof mat 09 by pulling the two side edges of the dustproof mat 09. With the opening of the dustproof pad 09 widened, the six-axis robotic arm moves the limiting arm gripping assembly 609 to the feeding position to grip the limiting arm 01, and then moves it above the widened dustproof pad 09, accurately inserting one end of the limiting arm 01 into the opening of the dustproof pad 09. After insertion, the two dustproof pad gripping cylinders 605 release the grippers and reset, the dustproof pad gripping cylinder 604 resets, and the dustproof pad 09 contracts and holds itself tightly in the corresponding position of the limiting arm 01 under its own elasticity. Finally, the six-axis robotic arm moves the limiting arm 01, with the dustproof pad 09 mounted on it, to the outer wall of the housing on the positioning fixture 22 and into the housing 04 in the limiting arm contouring limiting module (position 2202), completing the assembly and placement of the dustproof pad 09 and the limiting arm 01.

[0055] See Figure 20 The housing assembly mechanism 8 also includes a housing assembly stand 801. The housing moving component 2 includes a housing assembly linear module 802 (electric cylinder) fixedly mounted on the housing assembly stand 801, a housing assembly rotary motor 803 mounted on the moving end of the housing assembly linear module 802, an eccentric swing arm 2 mounted on the rotating end of the housing assembly rotary motor 803, and a housing assembly gripper cylinder 804 mounted on the eccentric swing arm 2 (the structure between the three features can be referenced as a whole to the arrangement of the oiling flip motor 204, the eccentric swing arm 1 205 and the oiling gripper cylinder 206).

[0056] When the device is in use, the linear module 802 for housing assembly controls the rotary motor 803 for housing assembly to descend to the outer wall contouring limit module (position three 2203) of the housing, clamping the housing two 05 through the gripper cylinder 804 for housing assembly. The linear module 802 for housing assembly controls the upward movement, and the rotary motor 803 for housing assembly flips. At this time, under the action of the eccentric swing arm two, the housing two 05 is placed above the outer wall of the housing and the contouring limit module one (position two 2202) of the limit arm. The linear module 802 for housing assembly controls the overall descent so that the housing two 05 is inserted along the rivet one 08.

[0057] See Figures 21-24The rivet flanging mechanism 9 also includes a flanging frame 901, a flanging press 902 fixedly mounted on the flanging frame 901, a flanging fixing plate 903 fixedly mounted on the flanging frame 901, two flanging guide posts 904 fixedly mounted on the flanging fixing plate 903, a flanging connecting block 905 slidably connected to the two flanging guide posts 904, a flanging head 906 fixedly mounted on the flanging connecting block 905, and a flanging positioning shell 907 slidably connected to the two flanging guide posts 904, at least two flanging positioning shells 907 fixedly mounted on the flanging positioning shell 907. The flange positioning guide post of the spring 908 is connected to the flange connecting block 905 by a threaded bolt at the top. The outer wall of the housing has a contour limiting module (position 3 2203) with a guide post / strip / plate. The flange positioning housing 907 has a guide groove for use with the guide post / strip / plate to achieve the guiding and positioning function, ensuring that the flange head 906 can be inserted into the hollow tube of the rivet 108 and the end of the hollow tube of the rivet 108 is outwardly formed under the pressure of the flange press 902.

[0058] See Figure 2 , Figure 24 The flanging inspection camera 1001 is mounted on the fixed plate 21 via a stand mounted on the fixed plate 21. The flanging and material transfer assembly 1002 is a six-axis robot with a finger-grip cylinder at one end. The unloading station is a set placement position (not shown), which can be an open waste bin or a waste conveyor belt, etc.

[0059] When the equipment is in use, the flanging inspection camera 1001 detects whether the flanging of rivet 08 is qualified. The specific setting standard can be whether the outer diameter after flanging is within the standard range. The captured image is compared with the big data pre-stored on the computer to obtain the information of whether it is qualified. This is a conventional technology in the field of image comparison. For unqualified products, the flanging and material transfer component 1002 grabs and moves them to the unloading station. For qualified products, the flanging and material transfer component 1002 grabs and reverses the workpiece as a whole so that the riveting insertion hole of the limiting arm 01 is facing away from the center of the turntable 20, and places it in the limiting arm contouring limiting module two (position four 2204).

[0060] See Figure 25 The oiling moving assembly 3 1102 uses a cylinder, which is fixed on a third oiling bracket 1101. The third oiling bracket 1101 is fixedly mounted on the fixed plate 21. A hollow tube 1103 for connecting the oiling nozzle is installed at the working end of the oiling moving assembly 3 1102. When the equipment is in use, the oiling moving assembly 3 1102 controls the hollow tube 1103 to descend and insert into the riveting hole on the limit arm 01 to spray oil.

[0061] See Figure 1The pre-assembly station 12 can be manually loaded. A material box 13 is set up next to it. The material box 13 contains rivet 2 03 (step rivet) and bracket 02. The operator aligns the through hole on the bracket 02 with the riveting hole on the limiting arm 01 at this position, and then inserts the rivet 2 03 from top to bottom.

[0062] See Figures 26-27 The riveting mechanism 14 includes a rivet combination press, which includes an assembly frame 1401, an assembly press 1402 mounted on the assembly frame 1401, and an assembly limiting guide assembly. The assembly limiting guide assembly includes two assembly limiting guide cylinders 1403 mounted and fixed on the assembly frame 1401. Each assembly limiting guide cylinder 1403 has a fixed insert 1404 at its working end that fits the shape of the outer peripheral wall of the rivet rod portion.

[0063] When the equipment is in use, the assembly limit guide cylinder 1403 controls the insert 1404 to limit the rod of the rivet 2 03, and then the assembly press 1402 controls the press head on it to descend and press the rivet 2 03 to the set position.

[0064] See Figure 28 The riveting mechanism 14 also includes a riveting assembly, which includes a riveting frame 1405, a riveting press 1406 mounted on the riveting frame 1405, and a riveting machine 1407. In use, the riveting press 1406 controls the press head to abut against the top surface of the rivet cap 203. Subsequently, the riveting machine 1407 rotates from bottom to top, ultimately achieving the riveting.

[0065] See Figure 29 It also includes a torque testing assembly 15, which includes a torque testing frame 1501 and a torque testing moving cylinder 1502 mounted on the torque testing frame 1501. A torque testing connecting plate 1503 is installed at the output end of the torque testing moving cylinder 1502. A torque testing motor 1504 is mounted and fixed on the torque testing connecting plate 1503. A torque sensor 1505 is mounted on the shaft of the torque testing motor 1504. A shift fork is installed below the torque sensor 1505. The shift fork includes two plugs 1506 that can be inserted into both sides of the bracket 02 respectively, and the distance between the two plugs 1506 is greater than the width of the bracket 02.

[0066] First, refer to Figure 3In the design of the outer wall of the housing and the contour limiting module two (position four 2204) of the positioning fixture 1 22, limit blocks are set on both sides of the bracket 02, so that the bracket 02 can only rotate within this range. Part of the bracket 02 extends out of the limit block, so that no matter where the bracket 02 is between the two limit blocks, the plug 1506 will always be positioned on both sides of the bracket 02. When the device is in use, the torque test moving cylinder 1502 drives the torque test connecting plate 1503 to move down, so that the plug 1506 is positioned on both sides of the bracket 02. Then the torque test motor 1504 rotates, and the plug 1506 drives the bracket 02 to rotate along the rivet two 03, and transmits the torque to the torque sensor 1505 to determine whether the product is qualified.

[0067] The production line also includes a rivet two oiling assembly 16, and the external oil supply module 3 includes an oil outlet pipe 4. The rivet two oiling assembly 16 includes an oiling frame 1603 and an oiling cylinder 1607 mounted on the oiling frame 1603. An oiling connecting frame is mounted on the working end of the oiling cylinder 1607, and the oil outlet end of the oil outlet pipe 4 is mounted on the oiling connecting frame. An oiling motor 1606 is also mounted on the oiling connecting frame, and an oiling head 1605 is mounted on the working end of the oiling motor 1606. In this embodiment, the oiling machine frame 1603 is fixed on an oiling switching cylinder 1602 (rodless cylinder). The oiling switching cylinder 1602 is fixedly mounted on an oiling connecting plate 1601, which is mounted on the housing assembly stand 801. Two oiling cylinders 1607 are mounted on the oiling machine frame 1603 with their output ends facing each other. Each oiling cylinder 1607 has an oiling connecting frame (not shown) fixed to its working end. A hollow oiling head 1604 is fixedly mounted on each oiling connecting frame. One end of the hollow oiling head 1604 is connected to an oil pipe, and the other end is used to abut against both ends of the rivet 2 03. An oiling head 1605 is mounted on the rotating end of the oiling motor 1606, which is used to spread the oil evenly on the end face of the rivet 2 03.

[0068] When the device is in operation, the two oiling cylinders 1607 control the two oiling connecting frames to move closer to each other, so that the hollow oiling heads 1604 are respectively placed on both sides of the rivet 2 03 on the riveted limit arm 01. Then, the external oil supply module 3 supplies oil. After that, the two oiling cylinders 1607 reset. Then, the oiling switching cylinder 1602 works, so that the two oiling heads 1605 are placed on both sides of the rivet 2 03 on the limit arm 01. After the oiling motor 1606 completes the oiling action, it resets.

[0069] See Figure 21A three-axis unloading assembly 17 is fixed on the flanging frame 901. It consists of three interconnected linear modules forming a three-axis motion structure. A finger-grip cylinder is fixed at its final output end. For the limit arm 01 that has completed the oiling of the rivet 2 03, the three-axis unloading assembly 17 controls the finger-grip cylinder to grip the material and place it on the qualified product conveyor belt 18 next to a turntable 20 for transportation and unloading.

[0070] Working principle and process: In this embodiment, two manual stations are set up for material loading, and the equipment needs to rotate twice to complete the complete assembly and inspection of the product (there is material at the corresponding position on the positioning fixture 22, and the relevant equipment will perform corresponding operations when the relevant equipment moves). Specifically, a manual station is set up at the dustproof mat assembly mechanism 6 for loading the limiting arm 01 and the dustproof mat 09 onto the positioning fixture 7. A manual station is set up at the pre-assembly station 12 for loading the housing 04 at position 1 2201 and the housing 05 at position 3 2203. At position 4 2204, the bracket 02 and the rivet 2 03 are pre-assembled onto the limiting arm 01 on which the housing 04 and the housing 05 are assembled.

[0071] When the equipment is working, the turntable 20 drives the positioning fixture 22 on it to move to the hollow rivet feeding mechanism 1 to feed rivet 08. Then, the oiling and flipping motor 204 in the housing oiling mechanism 2 controls the housing 04 to move from position 1 2201 to position 2 2202. Then, the housing oiling mechanism 2 applies oil to the inside of housing 04 and housing 05 at positions 2 2202 and 3 2203. Then, the spring and slider feeding mechanism 4 feeds slider 06 and spring 07. The loading of housing 04 and housing 05 at positions 2202 and 2203 is as follows: Next, the elasticity testing and oiling mechanism 5 tests the elasticity of the springs 07 and sliders 06 in housing 04 and housing 05; then, the dustproof pad assembly mechanism 6 installs the dustproof pad 09 on the limiting arm 01 and places the limiting arm 01 into housing 04 at position 2202; finally, the housing assembly mechanism 8 installs housing 05 at position 2203 into position 2203. In the housing 104 of shell 2202, rivet 108 is inserted. Then, rivet flanging mechanism 9 flanging rivet 108 completes the riveting of housing 104 and housing 205. Next, flanging detection and unloading mechanism 10 performs flanging detection, rejecting unqualified ones and moving qualified ones to position 4204 on positioning fixture 122. Next, limit arm oiling assembly 11 applies oil. Next, bracket 02 and rivet 203 are assembled at pre-assembly station 12. Next, press... Machine 1402 pre-tightens bracket 02, limiting arm 01, and rivet 2 03 at position four 2204; then, riveting machine 1407 and riveting press 1406 cooperate to rivet rivet 2 03, realizing the riveting between bracket 02 and limiting arm 01; then, torque testing component 15 tests whether the torque of bracket 02 is qualified; then, rivet 2 oiling component 16 performs oiling operation on rivet 2 03; finally, the finished product is unloaded by three-axis unloading component 17.
