When in use, the Y-axis moving component of the double-axis moving component 2 is controlled to drive the pneumatic gripper 210 to descend to grab the rivet transmitted in the feeding guide groove 302, and then drive it to rise, and the X-axis moving component is controlled to move the grabbed rivet to the workpiece transmitted on the rotating worktable 1;

[0040] Specifically, the X-axis moving assembly includes a support frame 201, a cylinder 202 is installed on one side of the top of the support frame 201, the output end of the cylinder 202 is connected to the side wall of the moving plate 205, the rear side of the moving plate 205 is fixedly connected with a sliding sleeve 204, and a guide rail 203 is installed on the front side of the top of the support frame 201. The inner wall of the sliding sleeve 204 is slidably connected with the outer wall of the guide rail 203. When in use, the cylinder 202 is controlled to drive the moving plate 205 to move, and the moving plate 205 drives the sliding sleeve 204 to move along the outer wall of the guide rail 203;

[0041] The Y-axis moving assembly includes a second cylinder 206, which is fixedly installed on the top of the moving plate 1 205. The output end of the second cylinder 206 is connected to a lifting plate 209, and the bottom end of the lifting plate 209 is fixedly connected to the top of the pneumatic gripper 210. The rear side of the lifting plate 209 is fixedly connected to a second sleeve 208. The front end of the moving plate 1 205 is fixedly connected to a second guide rail 207. The outer wall of the second guide rail 207 is slidably connected to the inner wall of the second sleeve 208. When in use, the second cylinder 206 is controlled to drive the lifting plate 209 to move up and down, thereby driving the pneumatic gripper 210 connected to the bottom end of the lifting plate 209 to move up and down. When the lifting plate 209 is lifted or lowered, the second sleeve 208 is driven to slide along the outer wall of the second guide rail 207.

[0042] In the above technology, the rivets transmitted in the feeding guide groove 302 are arranged and gathered together. When the double-axis moving component 2 drives the pneumatic gripper 210 to grab the rivets, it is easy to grab the rivets next to it, which affects the grabbing efficiency. For this reason, a movable feeding block 303 is set at the output end of the feeding guide groove 302, and a feeding card slot 304 corresponding to the feeding guide groove 302 is opened on the feeding block 303. When the X-axis moving component of the double-axis moving component 2 drives the moving plate 205 to reset, the feeding block 303 is affected by the thrust of the elastic rod 306 to move, so that the feeding The feeding slot 304 on the material block 303 is misaligned with the feeding guide groove 302, so that the rivets in the feeding slot 304 are separated from the rivets in the feeding guide groove 302, which is convenient for the pneumatic gripper 210 to grab the rivets. When the X-axis moving assembly drives the pneumatic gripper 210 on the front side of the moving plate 1 205 to move and load, the moving plate 1 205 drives the ladder frame 309 to move, and pushes the connecting rod 307 through the hypotenuse of the ladder frame 309, thereby pushing the feeding seat 301 to squeeze the elastic rod 306, driving the feeding slot 304 to correspond to the feeding guide groove 302;

[0043] Specifically: a feeding block 303 is provided at one end of the feeding seat 301, and the outer wall of the feeding block 303 is sleeved with a supporting frame 305 and is slidably connected to the inner wall of the supporting frame 305, and an elastic rod 306 is fixedly installed at the front end of the supporting frame 305, and the output end of the elastic rod 306 extends into the supporting frame 305 and is fixedly connected to the outer wall of the feeding block 303, and the end of the feeding block 303 away from the elastic rod 306 is fixedly connected to a connecting rod 307, and the outer wall of the connecting rod 307 is slidably connected to the inside of the side wall of the supporting frame 305, and the other end of the connecting rod 307 is rotatably connected to a roller 308, and a ladder frame 309 is fixedly connected to the lower left side of the movable plate 205, and the inner side of the ladder frame 309 is rollingly connected to the outer wall of the roller 308;

[0044] When in use, the pneumatic gripper 210 is driven to grab the rivet and load the material by controlling the dual-axis moving assembly 2. When the pneumatic gripper 210 on the front side of the moving plate 1 205 is driven to load the material, the moving plate 1 205 drives the ladder frame 309 to move, and the connecting rod 307 is pushed by the inclined edge of the ladder frame 309, thereby pushing the feeding seat 301 to squeeze the elastic rod 306, driving the feeding slot 304 to correspond to the feeding guide slot 302. , the rivet in the feeding guide groove 302 is inserted into the feeding card groove 304. When the feeding is completed and the X-axis moving assembly drives the moving plate 205 to reset, the feeding block 303 is moved by the thrust of the elastic rod 306, so that the feeding card groove 304 opened on the feeding block 303 is misaligned with the feeding guide groove 302, so that the rivet in the feeding card groove 304 is separated from the rivet in the feeding guide groove 302, which is convenient for the pneumatic gripper 210 to grab the rivet;

[0045] Furthermore, a push assembly 4 is provided at the left end of the feeding guide groove 302, and the push assembly 4 includes a push block 401 slidably connected to the inner wall of the feeding guide groove 302, and a rectangular groove is provided at one end of the feeding guide groove 302 away from the feeding block 303, and a spring 403 is fixedly connected to the outer side of the push block 401, and the outer side of the spring 403 is fixedly connected to the inner wall of the rectangular groove;

[0046] When in use, the pneumatic gripper 210 is driven to move by controlling the dual-axis moving assembly 2 to grab the rivet and load the material. When the X-axis moving assembly drives the pneumatic gripper 210 on the front side of the moving plate 1 205 to move and load the material, the moving plate 1 205 drives the ladder frame 309 to move, and the connecting rod 307 is pushed by the inclined edge of the ladder frame 309, thereby pushing the feeding seat 301 to squeeze the elastic rod 306, driving the feeding slot 304 to correspond to the feeding guide slot 302, and the rivet in the feeding guide slot 302 is pressed. The spring 1 403 pushes the rivet at the rightmost end of the feeding guide groove 302 to be clamped into the feeding clamping groove 304. When the feeding is completed and the X-axis moving assembly drives the moving plate 1 205 to reset, the feeding block 303 is moved by the thrust of the elastic rod 306, so that the feeding clamping groove 304 opened on the feeding block 303 is misaligned with the feeding guide groove 302, so that the rivet in the feeding clamping groove 304 is separated from the rivet in the feeding guide groove 302, which is convenient for the pneumatic gripper 210 to grab the rivet;

[0047] Example 2: Reference Figure 1 - Fig.11, which is different from the first embodiment, the end of the spring 1 403 away from the movable plate 2 404 is not fixedly connected to the inner wall of the rectangular groove. The point to be taken into consideration is that the rivets in the feeding guide groove 302 cannot be replenished in time by pushing the push block 401 through the fixed spring 1 403, and need to be replenished in a concentrated manner each time, which affects the use. For this reason, a feed port 413 is opened on the side wall of the feeding guide groove 302 close to one end of the rectangular groove, and a linkage component is provided between the rear end of the spring 1 403 and the connecting rod 307. Guide plates are installed at both ends of the outer side of the feed port 413, and a conveyor belt 5 for transmitting rivets is installed under the guide plate. When in use, the X-axis moving component drives the pneumatic gripper 210 on the front side of the movable plate 1 205 to move and load the material. The movable plate 1 205 drives the ladder frame 309 to move, and the connecting rod 307 is pushed by the hypotenuse of the ladder frame 309, thereby pushing the feeding seat 301 to squeeze the elastic rod 306, driving the feeding card slot 304 and the feeding guide groove 302, at the same time, the connecting rod 307 squeezes the spring 1 403 to the right through the linkage assembly, and the spring 1 403 pushes the push block 401 so that the rivet at the rightmost end of the feeding guide groove 302 is stuck in the feeding card slot 304. When the feeding is completed, the X-axis moving assembly drives the moving plate 1 205 to reset, and the feeding block 303 is moved by the thrust of the elastic rod 306, so that the feeding card slot 304 opened on the feeding block 303 is misaligned with the feeding guide groove 302, thereby making The rivets in the feeding slot 304 are separated from the rivets in the feeding guide slot 302, which is convenient for the pneumatic gripper 210 to grab the rivets. At the same time, the connecting rod 307 pulls the spring 1 403 to the left through the linkage assembly, driving the push block 401 to move to the left. As the push block 401 moves, the feed port 413 is opened, and the front end of the rivet outside the feed port 413 is pushed into the feeding guide slot 302 to fill the rivet stuck in the feeding slot 304, which is convenient to use.

[0048] Specifically, a guide rod 402 is fixedly installed on the inner wall of the rectangular groove, a spring 403 is fixedly connected to the outer side of the push block 401, a movable plate 404 is fixedly connected to the outer side of the spring 403, the movable plate 404 and the push block 401 are both slidably connected to the outer wall of the guide rod 402, a movable frame 405 is fixedly connected to the top of the movable frame 404, a connecting rod 406 is connected to the top of the movable frame 405, a vertical guide frame 407 is slidably connected to the outer wall of the connecting rod 406, a rotating disk 408 is provided above the vertical guide frame 407, an arc guide groove 409 is opened on the rotating disk 408, and a ring array of teeth 41 is distributed on the outer wall of the rotating disk 408 0, one side of the tooth 410 is meshed with a rack 411, one side of the rack 411 is fixedly connected to a connecting frame 412, and the other end of the connecting frame 412 is fixedly connected to the outer wall of the connecting rod 307. When in use, the X-axis moving assembly drives the moving plate 205 to move for loading, and pushes the connecting rod 307 through the hypotenuse of the ladder frame 309, thereby pushing the feeding seat 301 to squeeze the elastic rod 306, driving the feeding card slot 304 to correspond to the feeding guide groove 302, and the connecting rod 307 moves during the movement through the connecting frame 412 and the rack 411, and the movement of the rack 411 drives the rotating disk 408 meshed with it through the tooth 410 to rotate clockwise, Figure 5 It can be seen that the right end of the arc guide groove 409 is far away from the center of the rotating disk 408, and the left end is close to the center of the circle. Therefore, the rotation of the rotating disk 408 will drive the connecting rod 406 to move inward along the vertical guide frame 407, thereby pushing the moving frame 405 to drive the moving plate 2 404 to move to the right along the guide rod 2 402. The moving plate 2 404 moves to the right to squeeze the spring 1 403, and the spring 1 403 pushes the push block 401, so that the rivet at the rightmost end of the feeding guide groove 302 is stuck in the feeding card groove 304;

[0049] When the X-axis moving assembly drives the moving plate 205 to move and reset, the feed block 303 is moved by the thrust of the elastic rod 306, so that the feed slot 304 opened on the feed block 303 is misaligned with the feed guide groove 302, so that the rivet in the feed slot 304 is separated from the rivet in the feed guide groove 302, and at the same time, the connecting rod 307 drives the connecting frame 412 and the rack 411 to move and reset, and the movement of the rack 411 drives the rotating disk 408 engaged with it through the tooth 410 to rotate counterclockwise. The rotation of the rotating disk 408 drives the connecting rod 406 to move outward along the vertical guide frame 407, thereby pulling the movable frame 405 to drive the movable plate 404 to move to the left along the guide rod 402. The movable plate 404 pulls the push block 401 to move to the left through the spring 403. As the push block 401 moves, the feed port 413 is opened, and the front end of the rivet on the outside of the feed port 413 is pushed into the feed guide groove 302 to fill the one stuck in the feed card slot 304, which is easy to use.

[0050] process:

[0051] When the X-axis moving assembly drives the pneumatic gripper 210 on the moving plate 1 205 to move rightward to load materials: 1. The ladder frame 309 pushes the feeding block 303 through the connecting rod 307, so that the feeding slot 304 corresponds to the output end of the feeding guide slot 302; 2. The connecting rod 307 pushes the push block 401 through the linkage assembly, and the push block 401 pushes the rivet, so that the rivet at the rightmost end of the feeding guide slot 302 is inserted into the feeding slot 304 and the feed port 413 is blocked;

[0052] When the X-axis moving assembly drives the pneumatic gripper 210 on the moving plate 1 205 to move rightward and reset: 1. The feed block 303 is pushed and reset by the elastic rod 306, and the feed slot 304 is staggered with the feed guide slot 302; 2. The connecting rod 307 pulls the push block 401 through the linkage assembly, and then the push block 401 moves to the left and opens the feed port 413, and the front end of the rivet outside the feed port 413 is pushed into the feed guide slot 302 to fill the rivet stuck in the feed slot 304;

[0053] Furthermore, the pneumatic grasping forceps 210 include: a two-way pneumatic seat 6, the two-way pneumatic seat 6 includes a mounting seat 601, a two-way cylinder 602 is fixedly installed in the middle of the inner wall of the mounting seat 601, and movable guide grooves 604 are opened on both sides of the bottom end of the mounting seat 601, and the two output ends of the two-way cylinder 602 are fixedly connected to the connecting block 603, and the bottom end of the connecting block 603 is fixedly connected to the caliper 605, and two claws are provided on both sides of the bottom end of the caliper 605, and a clamping groove 606 corresponding to the rivet is opened on the inner side of each claw. When in use, the two-way cylinder 602 is controlled to drive the two connecting blocks 603 to move along the movable guide groove 604. When contracted, the rivet is clamped, and when extended, the two calipers 605 are separated.

[0054] Example 3: Reference Figure 1 - Fig.11 The defect in the second embodiment is that the distance between the two claws of the caliper 605 is fixed, and when the riveting holes of the profile on the rotating worktable 1 are loaded, it cannot be adjusted according to the positions of the large and small holes of the profile;

[0055] Conventional profiles that need to be riveted generally require two, and the two are connected by rivets passing through the holes. The size of the lower profile is fixed, and the size of the upper profile is adjusted according to the needs of different products. Although the size of the upper profile changes, the position of the hole and the distance from the side of the upper profile on the same side as the hole remain unchanged;

[0056] Therefore, the top of the caliper 605 is not fixedly connected to the bottom of the connecting block 603, and the caliper 605 is divided into two parts so that the two claws are independent, the guide block 608 is fixedly connected to the outside of the claw, and the guide frame 607 is fixedly connected to the bottom end of the connecting block 603. The inner wall of the guide frame 607 is slidably connected to the outer wall of the guide block 608. A fixed block is fixedly connected to the middle of the bottom end of the guide frame 607, and thrust springs 611 are fixedly connected to both sides of the fixed block. The other end of the thrust spring 611 is fixedly connected to the outer wall of the claw. One of the two calipers 605 is fixedly connected to a guide rod 609 on both sides, and a guide hole 610 is opened on both sides of the other caliper 605. The outer wall of the guide rod 609 is slidably connected to the inner wall of the guide hole 610, so that the claws on the opposite sides of the two calipers 605 are fixedly connected. Located in the same plane, a gathering frame 701 is installed on the top of the feeding block 303. When grabbing the rivet in the feeding slot 304, the Y-axis moving component is first controlled to drive the pneumatic gripper 210 to descend, and the two claws of the right caliper 605 are gathered inward due to the wide upper and narrow lower characteristics of the gathering frame 701, and are clamped into the groove at the bottom of the gathering frame 701. Due to the existence of the guide rod 609 and the guide hole 610, the caliper 605 on the opposite side is also gathered inward. When grabbing, the two-way cylinder 602 is controlled to pull the connecting block 603 to move inward along the moving guide groove 604 to drive the claws to move inward to grab the rivet. After the grabbing is completed, the pneumatic gripper 210 at the bottom of the Y-axis moving component rises, and the claws move outward under the influence of the thrust spring 611, and then are driven by the X-axis moving component to move horizontally to the top of the profile;

[0057] A placement seat 102 for placing the profile is installed on the rotating workbench 1, and a cylinder 3 702 is fixedly installed on both sides of the placement seat 102. A push plate 704 is fixedly connected to the output end of the cylinder 3 702, and a backing plate 703 is fixedly connected to the bottom end of the push plate 704. A semicircular groove is provided on the side of the push plate 704 away from the cylinder 3 702. The center of the semicircular groove is coaxial with the riveting hole of the profile, and the distance between the center of the semicircular groove and the backing plate 703 is equal to the distance between the riveting hole and the side edge of the upper profile on the same side;

[0058] After the pneumatic gripper 210 is moved horizontally to the top of the profile by the X-axis moving assembly, the Y-axis moving assembly is controlled to drive the pneumatic gripper 210 to descend for the first time. At this time, the bottom end of the side wall of the caliper 605 of the pneumatic gripper 210 is lower than the top surface of the push plate 704;

[0059] At this time, the control cylinder three 702 pushes the push plate 704 to move inward, and the push plate 704 contacts the side wall of the caliper 605 of the pneumatic gripper 210. At this time, the center of the rivet is coaxial with the center of the semicircular groove opened on one side of the push plate 704. As the push continues to move forward, the abutment plate 703 at the bottom end of the push plate 704 contacts the side wall of the upper profile, thereby fixing the upper profile while the position of the rivet is located directly above the riveting holes of the two riveted profiles. Then the Y-axis moving assembly is controlled to drive the rivet to descend and insert it into the riveting hole. After insertion, the two-way cylinder 602 is controlled to extend outward to release the restriction on the rivet, and then the Y-axis moving assembly is controlled to drive the pneumatic gripper 210 to rise, and then the rotary worktable 1 is controlled to drive the inserted rivet profile to move to the bottom of the riveting machine for riveting.
