Description

Technical Field

[0001] The invention relates to the technical field of chain processing, and in particular to an automatic cutting device for chain processing. Background Art

[0002] Chain is a common mechanical structure, which is composed of many links connected together by the connection points between adjacent rings. Each ring has a buckle, and they are connected through the buckles on adjacent rings to form a closed structure. In practical applications, chains are usually used to carry heavy objects, transmit power, provide transmission devices, etc. In the process of chain processing, in order to adjust the length of the chain, according to specific needs and designs, the chain needs to be cut into fragments of different lengths for assembly with other parts. In this case, the chain needs to be cut.

[0003] During use, the operator needs to strictly abide by the operating procedures of the equipment, operate according to the prescribed methods, and adjust the position of the pin on the chain to ensure that the cutting punch is accurately connected with the pin on the chain to avoid cutting quality problems caused by poor connection. However, in actual use, due to the complex chain structure, when cutting chains of different sizes, the sprocket is difficult to replace at any time, and the use of mismatched sprockets may cause the chain speed to decrease, thereby reducing the overall work efficiency. This will cause the equipment to bear a greater load, accelerate the wear and failure of the equipment, and cause the sprocket to be subjected to unnecessary excessive stress, greatly affecting the service life of the chain. When using a punch to push out the pin on the chain to cut the chain, it also increases the possibility of damaging the original structure of the chain, thereby destroying its original structure and integrity, affecting the normal use of the chain. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 9As shown, an automatic cutting device for chain processing comprises a body 1, a feeding frame 2 is fixedly installed on the upper part of the body 1, and also comprises a mounting frame 3, a fixed cylinder 4, a mounting assembly, a feeding assembly, a cutting frame 5, a driving assembly, a cutting assembly and a storage box 6. The mounting frame 3 is fixedly installed on the inner top wall of the feeding frame 2, and two fixed cylinders 4 are symmetrically and fixedly installed at both ends of the feeding frame 2. The fixed cylinder 4 is fixedly connected to the feeding frame 2, and a mounting assembly is installed inside each fixed cylinder 4. The mounting assembly comprises a rotating frame 7, a fixed ring 8, a rotating ring 9, a top frame 10, a spline shaft 11 and a pushing part. The ends of the four fixed cylinders 4 are rotatably installed with the rotating frames 7, the four fixed cylinders 4 are fixedly installed with the fixed rings 8, the four fixed rings 8 are rotatably installed with the rotating rings 9, the top frames 10 are slidably installed inside the four rotating rings 9, the tops of the four top frames 10 are fixedly installed with spline shafts 11, and the four rotating frames 7 are installed with pushing parts for pushing the top frames 10 to move on the rotating rings 9.

[0024] Specifically, when cutting the chain, first place the loading assembly in the working position, then start the pushing part, and push the top frame 10 to move in the rotating ring 9 through the pushing part. At the same time, the rotating ring 9 and the fixed ring 8 move relative to each other until the top frame 10 fixes the loading assembly through the spline shaft 11. Then, the chain can be placed on the loading assembly, and then the driving assembly is started to drive the loading assembly to move, thereby driving the chain to move until the chain moves to the upper part of the storage box 6. Then, the length of the chain is monitored. When the chain moves to the required length, the driving assembly can be closed and the position of the chain can be fixed. The cutting assembly can be started to cut off the chain of a determined length. The cut chain falls into the storage box 6, and the driving assembly can be restarted for the next cutting.

[0025] The above, such as Figure 4 , Figure 5 As shown, the pushing part includes a pushing cylinder 12, a screw 13, a nut 14 and a sliding plate 15. The pushing cylinder 12 is rotatably installed on one end of the four top frames 10 away from the spline shaft 11, the screw 13 is fixedly installed on the four rotating frames 7, the nuts 14 are threadedly mounted on the four screws 13, and the nuts 14 are fixedly connected to the pushing cylinder 12. Two sliding plates 15 are symmetrically and fixedly installed inside the four fixed cylinders 4, and the sliding plates 15 are slidably connected to the pushing cylinder 12.

[0026] Specifically, when controlling the top frame 10 to move inside the rotating ring 9, hold the corresponding rotating frame 7 and twist the rotating frame 7 to rotate. The rotating frame 7 drives the screw 13 to rotate. The screw 13 can push the pushing cylinder 12 to move along the axial direction of the pushing cylinder 12 under the action of the sliding plate 15 through the setting of the nut 14, thereby pushing the top frame 10 to move. When the top frame 10 drives the spline shaft 11 to move to a fixed position, stop twisting the rotating frame 7 to fix the position of the pushing cylinder 12, thereby fixing the position of the top frame 10.

[0027] like Figure 6 As shown, the feeding assembly is installed inside the mounting frame 3 for feeding, and the feeding assembly includes a rotating shaft 16, a transmission sprocket 17 and a spline sleeve 18. A rotating shaft 16 is arranged between the two fixed cylinders 4 at each end of the feeding frame 2, and the transmission sprocket 17 is detachably mounted on the two rotating shafts 16. Spline sleeves 18 are fixedly mounted at both ends of the two rotating shafts 16, and the spline sleeves 18 are adapted to the spline shaft 11. The spline sleeves 18 also include a meter meter 19 and a driven sprocket 20. The meter meter 19 is fixedly mounted on the cutting frame 5, and the output end of the meter meter 19 is detachably mounted with a driven sprocket 20.

[0028] Specifically, when installing the transmission sprocket 17, first install the transmission sprocket 17 of corresponding size on the rotating shaft 16, and place the rotating shaft 16 between two adjacent fixed cylinders 4, so that the rotating shaft 16 coincides with the axial position of the two adjacent top frames 10. At this time, the spline shaft 11 is pushed to move by the movement of the top frame 10 until the spline shaft 11 enters the spline sleeve 18, and the position of the transmission sprocket 17 can be fixed. Repeat this step, install the two transmission sprockets 17, and install the driven sprocket 20 with the same size as the transmission sprocket 17 on the output end of the meter 19, and the chain to be cut can be placed on the two transmission sprockets 17. As the transmission sprocket 17 rotates, the chain is driven to move until the chain and the driven sprocket 20 are engaged, and the meter 19 can be started to record the length of the chain passing through the driven sprocket 20, thereby achieving the effect of cutting the chain at a fixed length.

[0029] It should be noted that in order to ensure stable engagement between the driven sprocket 20 and the chain, the driven sprocket 20 is not located directly below the transmission sprocket 17 close to the cutting frame 5, but is staggered a certain distance so that the driven sprocket 20 is located obliquely below the side away from the other transmission sprocket 17, so that the chain passing through the transmission sprocket 17 close to the cutting frame 5 can be placed on the driven sprocket 20, which is convenient for recording the length of the sprocket.

[0030] like Figure 7As shown, the cutting frame 5 is fixedly mounted on the discharge end of the loading frame 2, and a driving assembly is installed between the two fixed cylinders 4 near the cutting frame 5 for driving the loading assembly. The driving assembly includes a driven gear 21, a transmission shaft 22, an intermediate gear 23, a motor 24, a driving gear 25 and a check portion. The two rotating rings 9 near the cutting frame 5 are fixedly mounted with driven gears 21, and a transmission shaft 22 is rotatably mounted on the mounting frame 3. Two intermediate gears 23 are symmetrically and fixedly mounted on the transmission shaft 22, and the intermediate gears 23 are meshed with the driven gear 21. The motor 24 is fixedly mounted on the loading frame 2, and a driving gear 25 is fixedly mounted on the output end of the motor 24, and the driving gear 25 is meshed with one of the intermediate gears 23. A check portion is installed on the two rotating rings 9 away from the cutting frame 5 for controlling the direction of the transmission sprocket 17.

[0031] Specifically, when the transmission sprocket 17 is driven to rotate, the motor 24 is started, and the motor 24 drives the driving gear 25 to rotate. The driving gear 25 is assembled with the intermediate gear 23 to rotate. The intermediate gear 23 is set through the transmission shaft 22, and the two intermediate gears 23 are driven to rotate at the same time, so as to drive the driven gear 21 to rotate. The driven gear 21 can drive the two top frames 10 close to the cutting frame 5 to rotate through the setting of the rotating ring 9. The two top frames 10 can drive the corresponding transmission sprocket 17 to rotate through the cooperation of the spline shaft 11 and the spline sleeve 18.

[0032] like Figure 5 As shown, the non-return portion includes a ratchet 26 and a pawl 27. The ratchet 26 is fixedly mounted on the two rotating rings 9 away from the cutting frame 5. Two pawls 27 are fixedly mounted inside the two fixed cylinders 4 away from the cutting frame 5. The pawls 27 are meshed with the ratchet 26.

[0033] Specifically, as the chain moves, the sprocket away from the cutting frame 5 rotates synchronously. At this time, the corresponding top frame 10 drives the corresponding rotating ring 9 to rotate, and the corresponding transmission ring drives the ratchet 26 to rotate. At this time, the pawl 27 is constantly disengaged from the ratchet 26. When the motor 24 is turned off and the movement of the chain is stopped, the pawl 27 engages with the ratchet 26, thereby fixing the rotation of the transmission sprocket 17 away from the cutting frame 5 to prevent the chain from moving backward, thereby determining the length of the chain. Under the action of the gravity of the chain, the transmission sprocket 17 away from the cutting frame 5 will not rotate forward.

[0034] like Figure 8 , Fig. 9As shown, a cutting assembly is installed on the cutting frame 5 for cutting the chain, a storage box 6 is fixedly installed at one end of the fuselage 1, and the storage box 6 is located at the lower part of the cutting frame 5. The cutting assembly includes a first electric cylinder 28, a sliding frame 29, a material return groove 30, a fixing part and a cutting part. The first electric cylinders 28 are fixedly installed on both sides of the cutting frame 5, and sliding frames 29 are fixedly installed on the output ends of the two first electric cylinders 28. The two sliding frames 29 are provided with a material return groove 30, and the two sliding frames 29 are installed with a fixing part for fixing the chain. The cutting part is installed on one of the sliding frames 29 for cutting the chain.

[0035] Specifically, when the chain needs to be cut, the first electric cylinder 28 is started, and the first electric cylinder 28 pushes the sliding frame 29 to move. The sliding frame 29 drives the fixing part to fix the position of the chain to prevent the chain from vibrating or slipping during the cutting process. Then the cutting part is started to push out the pin shaft at the corresponding position on the chain, so that the pin shaft enters the return groove 30, and the chain can be cut.

[0036] The above, such as Fig. 9 As shown, the fixing portion includes an arc-shaped gasket 31 and a convex ridge 32 . The arc-shaped gaskets 31 are symmetrically and fixedly mounted on the two sliding frames 29 , and a plurality of convex ridges 32 are evenly spaced on each arc-shaped gasket 31 .

[0037] Specifically, when the sliding frame 29 drives the arc-shaped gasket 31 to contact the chain, due to the arc surface setting of the arc-shaped gasket 31 and the setting of the ridge 32, the position of the chain can be firmly fixed, reducing the possibility of deviation and vibration of the chain when it is cut. The arc-shaped gasket 31 will be deformed to a certain extent after contacting the chain, reducing the risk of the chain being crushed.

[0038] The above, such as Fig. 9 As shown, the cutting part includes a positioning ring 33, a punch 34 and a second electric cylinder 35, wherein the positioning ring 33 is fixedly installed on the material withdrawal groove 30 on one of the sliding frames 29, the punch 34 is slidably installed in the positioning ring 33, the second electric cylinder 35 is installed on one of the sliding frames 29, and the output end of the second electric cylinder 35 is fixedly connected to the punch 34.

[0039] Specifically, after the position of the chain is fixed, the pin shaft that needs to be ejected just corresponds to the punch 34. At this time, the second electric cylinder 35 is started, and the second electric cylinder 35 pushes the punch 34 to move. Through the setting of the positioning ring 33, the movement of the punch 34 is more stable. When the punch 34 contacts the pin shaft, the pin shaft can be ejected.

[0040] In summary, when the chain needs to be cut, the transmission sprocket 17 is installed first. When installing the transmission sprocket 17, the transmission sprocket 17 of the corresponding size is first installed on the rotating shaft 16, and the rotating shaft 16 is placed between two adjacent fixed cylinders 4, so that the axis position of the rotating shaft 16 coincides with that of the two adjacent top frames 10. At this time, the corresponding rotating frame 7 is held and the rotating frame 7 is turned to rotate. The rotating frame 7 drives the screw 13 to rotate. The screw 13 can be set by the nut 14 to rotate under the action of the sliding plate 15. Next, push the pushing cylinder 12 to move along the axial direction of the pushing cylinder 12, thereby pushing the top frame 10 to move, and the top frame 10 moves in the rotating ring 9. At the same time, the rotating ring 9 and the fixed ring 8 move relative to each other until the top frame 10 pushes the spline shaft 11 into the spline sleeve 18. Then stop twisting the rotating frame 7 to fix the position of the pushing cylinder 12, thereby fixing the position of the top frame 10, and fixing the position of the transmission sprocket 17. Repeat this step to install the two transmission sprockets 17.

[0041] Then the chain to be cut is placed on the two transmission sprockets 17, which can drive the transmission sprocket 17 to rotate. At this time, the motor 24 is started, and the motor 24 drives the driving gear 25 to rotate. The driving gear 25 is mounted on the intermediate gear 23 to rotate. The intermediate gear 23 is set through the transmission shaft 22, and the two intermediate gears 23 are driven to rotate at the same time, which can drive the driven gear 21 to rotate. The driven gear 21 can drive the two top frames 10 close to the cutting frame 5 to rotate through the setting of the rotating ring 9. The two top frames 10 can drive the corresponding transmission sprocket 17 to rotate through the cooperation of the spline shaft 11 and the spline sleeve 18.

[0042] As the transmission sprocket 17 rotates, the chain is driven to move until the chain engages with the driven sprocket 20. The driven sprocket 20 is located obliquely below the transmission sprocket 17 near the cutting frame 5, so that the chain passing through the transmission sprocket 17 near the cutting frame 5 can be placed on the driven sprocket 20, which is convenient for recording the length of the sprocket. The meter 19 is started to record the length of the chain passing through the driven sprocket 20, thereby achieving the effect of fixed-length chain cutting. When the chain moves to the required length, the motor 24 can be turned off to start cutting the sprocket.

[0043] When it is necessary to cut the chain, the first electric cylinder 28 is started, and the first electric cylinder 28 pushes the sliding frame 29 to move. When the sliding frame 29 drives the arc gasket 31 to contact the chain, due to the arc surface setting of the arc gasket 31 and the setting of the convex ridge 32, the position of the chain can be firmly fixed, reducing the possibility of deviation and vibration of the chain when cutting. The arc gasket 31 will be deformed to a certain extent after contacting the chain, reducing the risk of the chain being crushed. After the position of the chain is fixed, the pin shaft that needs to be ejected just corresponds to the punch 34. At this time, the second electric cylinder 35 is started, and the second electric cylinder 35 pushes the punch 34 to move. Through the setting of the positioning ring 33, the movement of the punch 34 is more stable. When the punch 34 contacts the pin shaft, the pin shaft can be pushed out, and the cut chain falls into the storage box 6, and the next cutting can be carried out.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
