[0002] Clamps are often used for connecting and fastening and sealing at the interfaces of workpieces, especially pipe-like workpieces. Particularly in a vehicle production line, the interfaces of vehicle heating pipes often require clamp connection and fastening. Currently, in a vehicle production line, the method of manually sleeving a clamp with a vehicle heating pipe is usually adopted. However, the manual operation method requires a person to manually open the clamp and then sleeve it outside the vehicle heating pipe. This not only has a high labor intensity, high labor cost, but also low operation efficiency. Moreover, due to the large elasticity of the clamp, when manually opening the clamp, the contact area between the human hand and the clamp is small, resulting in difficulty in manually opening the clamp and easily causing hand pain or injury to the operator, which is inconvenient to operate and has potential safety hazards.

[0037] The present invention provides a device 100 for assisting in sleeving a workpiece with a clamp.

[0038] As Figures 1 to 6 shown, a device 100 for assisting the snap ring to sleeve a workpiece in this embodiment, the snap ring 200 has an integral structure, and the snap ring 200 includes a hoop 201 and two legs 202. The two support legs are cross - arranged and are respectively connected to both sides of the hoop 201. The snap ring automatic sleeving device for the workpiece includes a frame 10, a conveying mechanism 20, and a sleeving mechanism 30. Among them, the conveying mechanism 20 includes a conveying driving member 21 and a conveying rod 22. The conveying driving member 21 is installed on the frame 10, the conveying rod 22 is movably installed on the frame 10. One end of the conveying rod 22 is a discharge end 221, and the other end of the conveying rod 22 is connected to the conveying driving member 21. The snap ring 200 is sleeved outside the conveying rod 22. The conveying driving member 21 is used to drive the conveying rod 22 to move relative to the frame 10, so as to transport the snap ring 200 sleeved outside the conveying rod 22 to the discharge end 221 and discharge the snap ring 200 from the discharge end 221. The sleeving mechanism 30 includes a transfer table 31 and a sleeving driving member 32. The transfer table 31 and the sleeving driving member 32 are both installed on the frame 10. The transfer table 31 is located at the discharge end 221. The transfer table 31 is used to receive the snap ring 200 discharged from the discharge end 221 and guide the two legs 202 of the snap ring 200 into the sleeving driving member 32. The sleeving driving member 32 is used to drive the two legs 202 to move towards each other to make the hoop 201 in an open state or move away from each other to make the hoop 201 in a clamped state; the workpiece can be inserted into the hoop 201 in the open state, and when the hoop 201 is in the clamped state, it can be sleeved on the workpiece.

[0039] As Figure 1 and Figure 2 shown, the front end of the conveying rod 22 is connected to the conveying driving member 21, the rear end of the conveying rod 22 is the discharge end 221, and the transfer table 31 is located at the discharge end 221. It should be noted that, as Figure 5 and Figure 6 shown, the snap ring 200 includes a hoop 201 and two legs 202. Before being opened, the two legs 202 are always in a cross - arranged state, the hoop 201 is in a clamped state, and the two legs 202 are respectively connected to both sides of the hoop 201. Pushing the two legs 202 towards each other can make the hoop 201 gradually open to the open state. At this time, the workpiece can be inserted into the hoop 201. The workpiece can be a pipe structure sleeved with the snap ring 200, such as a vehicle's heating air duct. Stopping pushing or pushing the two legs 202 in the opposite direction, the two legs 202 can move away from each other under the action of their own elastic restoring force or under the action of the reverse pushing force, so that the hoop 201 returns to the clamped state and clamps the workpiece, realizing the sleeving of the snap ring 200 and the workpiece.

[0040] When the device 100 for assisting the socketing of a clamp onto a workpiece in the present invention is in use, first, the clamp 200 is sleeved outside the transfer rod 22. Subsequently, the transfer driving member 21 drives the transfer rod 22 to move relative to the frame 10, causing the clamp 200 to be transported to the discharge end 221 and discharged from the discharge end 221. Then, the transfer table 31 receives the clamp 200 and guides the two legs 202 of the clamp 200 into the socketing driving member 32. At this time, the hoop 201 of the clamp 200 is in a clamped state. Then, the socketing driving member 32 drives the two legs 202 of the clamp 200 to move towards each other, causing the hoop 201 of the clamp 200 to be in an open state. Subsequently, the workpiece is inserted into the open hoop 201. The socketing driving member 32 releases the two legs 202 of the clamp 200, causing the two legs 202 of the clamp 200 to move away from each other, thereby causing the hoop 201 to change to a clamped state to clamp the workpiece, so as to sleeve the clamp 200 outside the workpiece and realize the automatic socketing process of the clamp 200 and the workpiece. It can be understood that after the clamp 200 is socketed onto the workpiece, the workpiece with the clamp 200 socketed thereon is taken out, and by repeating the above steps, the batch socketing process of the clamp 200 outside the workpiece can be realized, accelerating the socketing rhythm and improving the operation efficiency.

[0041] The device 100 for assisting the socketing of a clamp onto a workpiece in the present invention can realize the automatic socketing of the clamp 200 and the workpiece, realize the automated operation process, eliminate the need for manual operation, have a high degree of automation, improve the operation efficiency, greatly reduce the labor intensity of workers, reduce the labor cost, and can also avoid the situation of hand injuries caused by direct contact between the human hand and the clamp 200 during manual operation, eliminating potential safety hazards. In addition, the present invention can also realize the batch socketing process of the clamp 200 outside the workpiece, accelerate the socketing rhythm, and greatly improve the operation efficiency.

[0042] In an embodiment, a chute 311 with one side closed and the other side open is provided inside the transfer table 31. The two ends of the chute 311 respectively form a feed port 312 and a discharge port 313, and the socketing driving member 32 is arranged near the discharge port 313; an insertion cavity 314 is also provided at a position near the discharge port 313 on the closed side of the chute 311. The clamp 200 discharged from the discharge end 221 can enter the chute 311 from the feed port 312 and slide towards the discharge port 313 in the chute 311 to reach the discharge port 313, so as to guide the hoop 201 of the clamp 200 to the insertion cavity 314 through the chute 311 and guide the legs 202 into the socketing driving member 32; when the workpiece passes through the open side of the chute 311 and is inserted into the open hoop 201, it is in plug-in fit with the insertion cavity 314.

[0043] As Figure 1 and Figure 2As shown, the chute 311 is inclined downward from front to back. The upper end of the chute 311 forms a feed inlet 312, and the lower end of the chute 311 forms a discharge outlet 313, so that the clamp 200 entering the chute 311 from the feed inlet 312 can slide quickly towards the discharge outlet 313. The bottom of the chute 311 is a closed side, and the top of the chute 311 is an open side, so that the workpiece can be inserted from the open side.

[0044] Specifically, after the clamp 200 is discharged from the discharge end 221, the clamp 200 slides into the chute 311 from the feed inlet 312 and slides quickly towards the discharge outlet 313 in the chute 311. During the process of the clamp 200 sliding in the chute 311, the chute 311 plays a role in limiting and guiding the clamp 200, and can accurately guide the clamp 200 to slide quickly towards the direction of the discharge outlet 313, so that the two legs 202 of the clamp 200 can accurately extend into the socket driving member 32. When the clamp 200 slides to the discharge outlet 313, the hoop 201 of the clamp 200 is located at the insertion cavity 314, and the two legs 202 of the clamp 200 extend into the socket driving member 32. The socket driving member 32 drives the two legs 202 of the clamp 200 to move towards each other, so that the hoop 201 of the clamp 200 is in an open state. The workpiece is inserted from the open side of the chute 311 into the insertion cavity 314 and is in plug-in fit with the insertion cavity 314. Through the insertion cavity 314, the workpiece can be quickly and accurately positioned, improving the quickness and accuracy of the socket connection between the clamp 200 and the workpiece.

[0045] In one embodiment, the socket driving member 32 is a finger cylinder 32a. Clamping blocks 322 are respectively installed on the two jaws 321 of the finger cylinder 32a. The two clamping blocks 322 are arranged towards each other, and limiting holes 323 are opened at positions of the two clamping blocks 322 close to the discharge outlet 313. When the clamp 200 slides in the chute 311 to the discharge outlet 313, the two legs 202 are respectively inserted into the two limiting holes 323.

[0046] As Figure 3 shown, the two clamping blocks 322 are respectively installed on the two jaws 321 and are arranged towards each other. The limiting holes 323 of each clamping block 322 are close to the discharge outlet 313 of the transfer table 31. When the two legs 202 of the clamp 200 are respectively inserted into the two limiting holes 323, the two jaws 321 of the finger cylinder 32a move towards each other to drive the clamping blocks 322 to move towards each other, and further make the two legs 202 of the clamp 200 move towards each other, so that the hoop 201 is in an open state. The workpiece is inserted into the hoop 201, and then the two jaws 321 of the finger cylinder 32a move away from each other to drive the clamping blocks 322 to move away from each other, releasing the two legs 202 of the clamp 200. The two legs 202 of the clamp 200 can move away from each other under the action of their own elastic restoring force, so that the hoop 201 is in a clamped state.

[0047] The finger cylinder 32a in this embodiment can adopt the existing technology. Since the two legs 202 of the clamp 200 are respectively inserted into the two limit holes 323 during the movement towards or away from each other, the limit holes 323 can limit the legs 202, effectively preventing the two legs 202 of the clamp 200 from detaching from the jaws 321 of the finger cylinder 32a, with high reliability.

[0048] In one embodiment, a first sensor 33 is provided at a position on the transfer table 31 close to the discharge port 313. The first sensor 33 passes through the transfer table 31 and its sensing end faces towards the inside of the chute 311.

[0049] As Figure 2 shown, the first sensor 33 passes through the left side of the transfer table 31 and is provided close to the discharge port 313. It can be understood that the first sensor 33 and the socket driving member 32 can be communicatively connected to the control device. During the operation of the device 100 for assisting the clamp to socket the workpiece, when the first sensor 33 senses that the clamp 200 slides to the discharge port 313, the control device controls the socket driving member 32 to drive the two jaws 321 to move towards each other, so that the two legs 202 of the clamp 200 keep the clamp 200 in an open state, improving the automation degree of the device 100 for assisting the clamp to socket the workpiece, which is convenient and fast.

[0050] In one embodiment, the socket mechanism 30 further includes a detection component 34. The detection component 34 includes a telescopic rod 341, an elastic member 342 and a second sensor 343. The transfer table 31 is provided with a channel 315 located at the bottom of the insertion cavity 314 and communicating with the insertion cavity 314. The telescopic rod 341 is slidably disposed through the insertion cavity 314 and the channel 315 and extends out of the transfer table 31. And the telescopic rod 341 is provided with an insertion block 344 located in the insertion cavity 314. An elastic member 342 is connected between the insertion block 344 and the bottom of the insertion cavity 314. The second sensor 343 is installed on the frame 10 and is located below the transfer table 31. The sensing end of the second sensor 343 faces one end of the telescopic rod 341 extending out of the transfer table 31.

[0051] As Figure 1 and Figure 4As shown, the insertion block 344 in the insertion cavity 314 is arranged at the upper end of the telescopic rod 341. The upper end of the elastic member 342 abuts against the lower end of the insertion block 344, and the lower end of the elastic member 342 abuts against the bottom of the insertion cavity 314. The frame 10 includes a bottom plate 12 and a triangular bracket 11 mounted on the bottom plate 12. The triangular bracket 11 includes two mounting surfaces. The second sensor 343 is located below the adapter table 31, and both the second sensor 343 and the bottom of the adapter table 31 are mounted on the same mounting surface of the triangular bracket 11. During the use of the device 100 for assisting in sleeving a clamp on a workpiece, when the workpiece extends into the insertion cavity 314, the workpiece will abut against the insertion block 344 and be inserted into the insertion cavity 314 in an insertion fit, and push the telescopic rod 341 to move towards the sensing end of the second sensor 343, that is, push the telescopic rod 341 to move obliquely forward, and the elastic member 342 is compressed.

[0052] Understandably, the second sensor 343, the sleeving driving member 32, and the conveying driving member 21 can be communicatively connected to the control device. When the second sensor 343 senses that one end of the telescopic rod 341 extends out of the adapter table 31, it indicates that the workpiece is accurately inserted into the insertion cavity 314 and inserted in place. At this time, the control device controls the sleeving driving member 32 to drive the two jaws 321 to move away from each other to loosen the two legs 202 of the clamp 200, further improving the automation degree of the device 100 for assisting in sleeving a clamp on a workpiece, which is convenient and fast. And, when the clamp 200 and the workpiece complete the sleeving and the workpiece is taken out of the insertion cavity 314, the telescopic rod 341 and the insertion block 344 can quickly return to their original positions under the action of the restoring force of the elastic member 342 to wait for the next workpiece to be inserted into the insertion cavity 314. It should be noted that when the second sensor 343 senses that one end of the telescopic rod 341 extends out of the adapter table 31, the control device will also control the conveying driving member 21 to drive the conveying rod 22 to move relative to the frame 10 to transport the clamp 200 to the discharge end 221 and discharge the clamp 200 from the discharge end 221, further improving the automation degree of the device 100 for assisting in sleeving a clamp on a workpiece.

[0053] In one embodiment, the conveying driving member 21 is a motor 21a, the conveying rod 22 is a conveying lead screw 22a. The conveying lead screw 22a is horizontally arranged and rotatably penetrates through the frame 10. The motor 21a is installed on the frame 10 and the output shaft of the motor 21a is coaxially arranged with the conveying lead screw 22a. One end of the rotating shaft of the motor 21a is connected to one end of the conveying lead screw 22a. The conveying mechanism 20 further includes a hanging rod 23. One end of the hanging rod 23 is installed on the frame 10 and the other end of the hanging rod 23 is a discharging end 231. The hanging rod 23 is located above the conveying lead screw 22a and is arranged parallel to the conveying lead screw 22a. The discharging end 231 and the discharging end 221 are arranged vertically opposite to each other. The hoop 201 of a plurality of clamps 200 is slidably sleeved outside the hanging rod 23, and the two legs 202 of the plurality of clamps 200 are respectively abutted against both sides of the conveying lead screw 22a. The motor 21a is used to drive the conveying lead screw 22a to rotate, so that the clamp 200 moves towards the discharging end 231 through the cooperation of the conveying lead screw 22a and the legs 202 and is discharged from the discharging end 231 and the discharging end 221.

[0054] As Figure 1 shown, the extending direction of the bottom plate 12 is the front-back direction. The frame 10 is further installed on the first vertical plate 13 and the second vertical plate 14 which are sequentially arranged at intervals along the front-back direction on the bottom plate 12. The motor 21a is horizontally arranged and installed on the front side of the first vertical plate 13, and the output shaft of the motor 21a rotatably penetrates through the first vertical plate 13. A connecting seat is installed on the rear side of the second vertical plate 14. The conveying lead screw 22a rotatably penetrates through the connecting seat and the second vertical plate 14. The conveying lead screw 22a is coaxially arranged with the output shaft of the motor 21a. The front end of the conveying lead screw 22a is connected to the output shaft of the motor 21a through a coupling 29, and the rear end of the conveying lead screw 22a is the discharging end 221. The frame 10 further includes a fixing plate 253. The fixing plate 253 is located on the front side of the second vertical plate 14. The front end of the hanging rod 23 is installed on the fixing plate 253, and the rear end of the hanging rod 23 is the discharging end 231.

[0055] When the device 100 for assisting the clamping of the workpiece by the clamp of the present invention is in use, first, the hoops 201 of a plurality of clamps 200 are sequentially sleeved outside the hanging rod 23. The hoop 201 is slidably engaged with the hanging rod 23. At this time, the two legs 202 of each clamp 200 are respectively abutted against both sides of the conveying lead screw 22a. Subsequently, the motor 21a drives the conveying lead screw 22a to rotate. The threads on the conveying lead screw 22a push the two legs 202 of the clamp 200 backward during the rotation process, so that the plurality of clamps 200 move backward synchronously along the conveying lead screw 22a until the plurality of clamps 200 are sequentially discharged from the discharging end 231 of the hanging rod 23 and the discharging end 221 of the conveying lead screw 22a, so as to realize the batch conveying process of the clamp 200. The structural design is ingenious and the use is flexible and convenient.

[0056] Further, the conveying mechanism 20 further includes a material distributing component 24 located below the conveying lead screw 22a. The material distributing component 24 includes a column 241 and a magnet block 242. The bottom of the column 241 is installed on the frame 10, and the magnet block 242 is installed on the top of the column 241 and close to the conveying lead screw 22a. The magnet block 242 is used to attract the support feet 202.

[0057] As Figure 1 shown, during the process of the batch of clamps 200 moving backward synchronously, there may be a situation where the support feet 202 of multiple clamps 200 overlap each other and interfere. In this embodiment, the conveying mechanism 20 further includes a material distributing component 24. The material distributing component 24 is located between the second vertical plate 14 and the triangular bracket 11. The bottom of the column 241 is installed on the bottom plate 12, and the magnet block 242 is installed on the top of the column 241 and below the conveying lead screw 22a. During the process of multiple clamps 200 moving backward synchronously along the conveying lead screw 22a, when each clamp 200 passes above the magnet block 242, due to the attraction of the magnet block 242, the clamping feet of each clamp 200 are pulled forward, so as to separate the overlapping support feet 202, and then separate the multiple overlapping clamps 200 one by one, which is conducive to the process of multiple clamps 200 being discharged sequentially from the discharging end 231 of the hanging rod 23 and the discharging end 221 of the conveying lead screw 22a, thereby improving the reliability and accuracy of the socket connection between the clamp 200 and the workpiece.

[0058] In one embodiment, the conveying mechanism 20 further includes a lifting component 25. The lifting component 25 includes a mounting seat 251, a swing shaft 252, a fixing plate 253 and a handle 254. The mounting seat 251 is installed on the top of the frame 10. One end of the swing shaft 252 is hinged to the mounting seat 251. The other end of the swing shaft 252 is installed with a fixing plate 253. The swing shaft 252 abuts against the top of the frame 10, and the fixing plate 253 is installed with a handle 254. One end of the hanging rod 23 far from the discharging end 231 is installed on the fixing plate 253.

[0059] As Figure 1 shown, the mounting seat 251 is installed at the rear side of the upper end of the first vertical plate 13. The swing shaft 252 abuts against the top of the second vertical plate 14, and the front end of the swing shaft 252 is hinged to the mounting seat 251. The rear end of the swing shaft 252 is connected to the front side of the fixing plate 253. The rear side of the fixing plate 253 is installed with a handle 254. The front end of the hanging rod 23 is installed on the rear side of the fixing plate 253.

[0060] When multiple clamps 200 need to be sleeved outside the hanging rod 23, first lift the handle 254 so that the swinging shaft 252 and the hanging rod 23 are driven by the fixing plate 253 to swing upward around the mounting base 251, thereby lifting the hanging rod 23, making the discharging end 231 of the hanging rod 23 leave the top of the transfer table 31 upward, so that the discharging end 231 of the hanging rod 23 does not interfere with the transfer table 31. Then it is conducive to sleeving the hoop rings 201 of multiple clamps 200 from the discharging end 231 of the hanging rod 23 outside the hanging rod 23 in batches. After the sleeving is completed, the handle 254 can be lowered to make the hanging rod 23 return to its original position, so that the discharging end 231 of the hanging rod 23 returns to the position of the feeding port 312 of the transfer table 31, and the swinging shaft 252 then abuts against the top of the second vertical plate 14 again, playing a supporting role for the hanging rod 23. The structure design is ingenious and the use is flexible and convenient.

[0061] In one embodiment, the conveying mechanism 20 further includes a cylinder 26. A connecting frame 27 is installed on the transfer table 31. The cylinder 26 is installed on the connecting frame 27 and is located above the transfer table 31. The output shaft of the cylinder 26 is coaxially arranged with the hanging rod 23 and the output end of the output shaft of the cylinder 26 can abut against the discharging end 231.

[0062] As Figure 1 shown, the connecting frame 27 is installed on the right side of the transfer table 31. The cylinder 26 is installed on the top of the connecting frame 27 and is located above the transfer table 31. And the cylinder 26 is located behind the hanging rod 23 and is arranged corresponding to the discharging end 231 of the hanging rod 23. The output shaft of the cylinder 26 is coaxially arranged with the hanging rod 23.

[0063] During the process of the conveying lead screw 22a and the hanging rod 23 transporting multiple clamps 200, the output shaft of the cylinder 26 abuts against the discharging end 231 of the hanging rod 23. Multiple clamps 200 move from front to back as the conveying lead screw 22a rotates. The last clamp 200 located at the back is discharged from the discharging end 231 and the discharging end 221 and is hung on the front end of the output shaft of the cylinder 26. Subsequently, the output shaft of the cylinder 26 quickly contracts backward, throws the clamp 200 to the feeding port 312 of the transfer table 31 and then quickly extends to abut against the discharging end 231 again, realizing the process of picking up and delivering a single clamp 200, and avoiding the situation that several clamps 200 fall into the feeding port 312 at the same time and affect the socket connection with the workpiece. After the clamp 200 is socket-connected with the workpiece, the cylinder 26 operates according to the above steps to realize the process of picking up and delivering the next clamp 200, thereby realizing the single multiple cycle picking up and delivering process of batch clamps 200, realizing the socket connection process of batch clamps 200 with batch workpieces in sequence, and improving the socket connection accuracy and socket connection efficiency of the clamp 200 and the workpiece.

[0064] In one embodiment, the transfer mechanism 20 further includes a third sensor 28 installed on the top of the adapter table 31. The sensing end of the third sensor 28 faces the output end of the output shaft of the cylinder 26, and the third sensor 28 is located below the output end. As Figure 2 shown, the third sensor 28 is installed on the left side of the top of the adapter table 31. The sensing end of the third sensor 28 faces the output end of the output shaft of the cylinder 26, and the third sensor 28 is located below the output end. It can be understood that the third sensor 28, the motor 21a, and the cylinder 26 are all communicatively connected to the control device.

[0065] During the process of the transfer screw 22a and the hanging rod 23 transporting a plurality of clamps 200, the control device controls the output shaft of the cylinder 26 to extend until it abuts against the discharging end 231 of the hanging rod 23. The plurality of clamps 200 move from front to back as the transfer screw 22a rotates. The last clamp 200 located at the rear is discharged from the discharging end 231 and the discharging end 221 and is hung on the front end of the output shaft of the cylinder 26. When the third sensor 28 senses that there is a clamp 200 at the front end of the output shaft of the cylinder 26, the control device controls the motor 21a to stop driving the transfer screw 22a from rotating, so that the plurality of clamps 200 on the transfer screw 22a stop moving backward. Moreover, the control device controls the output shaft of the cylinder 26 to quickly contract backward, and throws the clamp 200 hung on the front end of the output shaft of the cylinder 26 to the feeding port 312 of the adapter table 31, further improving the automation degree of the device 100 for assisting the clamp to sleeve the workpiece, which is convenient and fast.
