[0082] The tail shearing clamping device 1000 of the embodiment of the present application is described in detail below with reference to the drawings.

[0083] Referring to Figures 1 to 5As shown, the wire tail cutting and clamping device 1000 provided by the embodiment of the present application includes a wire cutting plier 10 and a wire cutting clamp 20; the wire cutting clamp 20 is fixedly integrated with the wire cutting plier 10 and can be synchronously opened / closed with the wire cutting plier 10, so as to correspondingly cut and clamp the same wire when being synchronously closed.

[0084] Based on the above, it can be clear that the present application is mainly used as the wire tail cutting and clamping device 1000 capable of synchronously cutting and clamping the same wire in specific implementation.

[0085] Specifically, when the present application is applied, the present application is applied to the sleeve threading and winding rubber coating machine commonly used in the prior art. After the winding on the surface of the coil framework to be processed is completed, a small section of wire tail is left outside the pin. The present application is installed on the moving member capable of moving back and forth in at least one direction in the sleeve threading and winding rubber coating machine commonly used in the prior art. The present application can be used to cut the corresponding wire tail to the same length. The cut wire tail is synchronously clamped. Then, the present application is moved to the desired position by the moving member. The cut and clamped wire tail can be transferred, such as being transferred to a wire tail collection box for collection. In this way, the cut wire tail will not fly and scatter everywhere and fall into every corner of the machine surface, so that the machine can be kept clean and tidy, the machine needs to be cleaned less frequently, the labor is saved, and the machine parts will not be damaged due to frequent contact with the machine, so that the service life of the machine is long.

[0086] Furthermore, the present application has strong practicality and good use effect.

[0087] Further, in specific implementation, according to one embodiment of the present application, the wire cutting plier 10 includes a first cutter head 101 and a second cutter head 102 capable of being opened / closed to cut the wire;

[0088] Based on this, in the technical solution, the wire cutting clamp 20 includes a first wire clamping block 201 fixedly arranged on the surface of the first cutter head 101 and a second wire clamping block 202 fixedly arranged on the surface of the second cutter head 102.

[0089] In this way, when the first cutter head 101 and the second cutter head 102 of the wire cutting plier 10 are opened / closed, the first wire clamping block 201 and the second wire clamping block 202 can be synchronously opened / closed, that is, when the first cutter head 101 and the second cutter head 102 of the wire cutting plier 10 are closed to cut the wire tail, the first wire clamping block 201 and the second wire clamping block 202 can be synchronously closed to clamp the cut wire tail, so that the present application has the functions of synchronous cutting and clamping of the wire tail.

[0090] Preferably, according to an embodiment of the present application, the first blade head 101 has a first blade 1011 facing the second blade head 102, the second blade head 102 has a second blade 1021 facing the first blade 1011, and the first blade 1011 and the second blade 1021 are closed to each other to cut off the wire end.

[0091] Correspondingly, in the present application, the first wire clamping block 201 has a first wire clamping surface 2011 facing the second wire clamping block 202, and the second wire clamping block 202 has a second wire clamping surface 2021 facing the first wire clamping surface 2011; at the wire cutting and clamping position in the wire length direction, the distance between the first wire clamping surface 2011 and the second wire clamping surface 2021 is slightly greater than the distance between the first blade 1011 and the second blade 1021, and the first wire clamping surface 2011 and the second wire clamping surface 2021 are closed to each other to clamp the cut-off wire end.

[0092] Preferably, at the wire cutting and clamping position in the wire length direction, the distance between the first wire clamping surface 2011 and the second wire clamping surface 2021 is equal to or slightly less than the sum of the distance between the first blade 1011 and the second blade 1021 and the outer diameter of the wire to be cut, so that the wire can be reliably clamped by the first wire clamping surface 2011 of the first wire clamping block 201 and the second wire clamping surface 2021 of the second wire clamping block 202 at the moment when the wire is cut off by the wire cutter 10.

[0093] Further, in specific implementation, according to an embodiment of the present application, the first wire clamping block 201 is detachably connected with the first blade head 101, the second wire clamping block 202 is detachably connected with the second blade head 102, and the distance between the first wire clamping block 201 and the second wire clamping block 202 is adjustable.

[0094] In the preferred scheme, a first long limiting groove 1012 is formed in the surface of the first blade head 101 along the direction perpendicular to the first blade 1011, and a first lock hole 1013 is formed in the bottom of the first long limiting groove 1012; a second long limiting groove 1022 is formed in the surface of the second blade head 102 along the direction perpendicular to the second blade 1021, and a second lock hole 1023 is formed in the bottom of the second long limiting groove 1022;

[0095] Based on this, in the embodiment, the first clamping block 201 has a first clamping protrusion 2012 which is adapted to be clamped and can slide along the length direction of the first long limiting groove 1012, and the surface of the first clamping block 201 is provided with a first screw groove 2013 which passes through the first clamping protrusion 2012 and is opposite to the first locking hole 1013, and the length direction of the first screw groove 2013 is the same as that of the first long limiting groove 1012; the first clamping block 201 is fixed to the first tool bit 101 by rotating the fastening bolt A into the first screw groove 2013 and the first locking hole 1013.

[0096] Based on this, in the embodiment, the second clamping block 202 has a second clamping protrusion 2022 which is adapted to be clamped and can slide along the length direction of the second long limiting groove 1022, and the surface of the second clamping block 202 is provided with a second screw groove 2023 which passes through the second clamping protrusion 2022 and is opposite to the second locking hole 1023, and the length direction of the second screw groove 2023 is the same as that of the second long limiting groove 1022; the second clamping block 202 is fixed to the second tool bit 102 by rotating the fastening bolt B into the second screw groove 2023 and the second locking hole 1023.

[0097] Therefore, when the locking bolt A is loosened, the first clamping protrusion 2012 can slide along the length direction of the first long limiting groove 1012, so that different positions of the first screw groove 2013 can be opposite to the first locking hole 1013, and then the locking bolt A is tightened to fix the first clamping block 201, so that the position of the first clamping surface 2011 of the first clamping block 201 on the length of the first long limiting groove 1012 is adjustable.

[0098] Similarly, when the locking bolt B is loosened, the second clamping protrusion 2022 can slide along the length direction of the second long limiting groove 1022, so that different positions of the second screw groove 2023 can be opposite to the second locking hole 1023, and then the locking bolt B is tightened to fix the second clamping block 202, so that the position of the second clamping surface 2021 of the second clamping block 202 on the length of the second long limiting groove 1022 is adjustable.

[0099] Further, the clamping position in the length direction of the wire is adjusted so that the distance between the first clamping surface 2011 of the first clamping block 201 and the second clamping surface 2021 of the second clamping block 202 is adjustable, so that different outer diameters of wires can be clamped in specific use, so that the application has strong flexibility, strong adaptability and better use effect.

[0100] And, in the technical solution, according to one embodiment of the application, the wire cutting pliers 10 further comprises a pivot 103, a first operating handle 104 and a second operating handle 105;

[0101] Wherein, the rear end of the first cutter head 101 is rotatably connected with the rear end of the second cutter head 102 through the pivot 103; the first operating handle 104 is fixedly arranged at the rear of the first cutter head 101; and the second operating handle 105 is fixedly arranged at the rear of the second cutter head 102.

[0102] Therefore, the wire cutting pliers 10 is shaped as an X-shaped structure, so that the wire cutting pliers 10 and the wire clamp 20 can be synchronously opened / closed by holding the first operating handle 104 and the second operating handle 105.

[0103] Further, in the specific implementation, according to one embodiment of the application, the wire cutting pliers 10 further comprises a pressing spring 106;

[0104] Wherein, the pressing spring 106 is fixedly arranged between the first operating handle 104 and the second operating handle 105, and is used to separate the first operating handle 104 and the second operating handle 105, so that the first cutter head 101 and the second cutter head 102 are in an open state at the beginning.

[0105] Therefore, without using the application, the first cutter head 101 and the second cutter head 102 are in an open state at the beginning due to the reaction force of the pressing spring 106, and the first wire clamping block 201 and the second wire clamping block 202 are also in an open state at the beginning. Only when the first operating handle 104 and the second operating handle 105 are held or pressed, the first cutter head 101 and the second cutter head 102 are in a closed state during use, and the first wire clamping block 201 and the second wire clamping block 202 are also in a closed state during use.

[0106] It should be noted that, in the specific implementation, according to one embodiment of the application, the application further comprises a driving member 30 for controlling the opening / closing of the wire cutting pliers 10; and the driving member 30 is fixedly connected with the wire cutting pliers 10.

[0107] Therefore, by arranging the driving member 30, manual operation of the wire cutting pliers 10 to force the wire clamp 20 and the wire cutting pliers 10 to be synchronously opened / closed is avoided, so that the application is labor-saving.

[0108] Preferably, in the technical solution, according to one embodiment of the application, the driving member 30 comprises a cylinder sleeve 301 and a cylinder piston 302;

[0109] Wherein, the front end of the cylinder sleeve 301 is provided with a connecting port 3011, and the rear end is provided with a gas inlet and outlet 3012; the first operating handle 104 and the second operating handle 105 extend into the cylinder sleeve 301 from the connecting port 3011, and the both ends of the rotating shaft 103 are fixed at the connecting port 3011, so that the thread cutting pliers 10 and the cylinder sleeve 301 are fixed as a whole.

[0110] Based on this, in the embodiment, the cylinder piston 302 is slidably arranged in the rear part of the cylinder sleeve 301, and the front end is provided with a pushing inner cavity 3021 with gradually decreasing inner diameter facing the rear; the rear end of the first operating handle 104 and the rear end of the second operating handle 105 are both abutted to the front inner wall of the pushing inner cavity 3021.

[0111] When the gas is introduced into the cylinder sleeve 301 through the gas inlet and outlet 3012 to push the cylinder piston 302 to slide forward, the pushing inner cavity 3021 squeezes the first operating handle 104 and the second operating handle 105, so that the first cutter head 101 and the second cutter head 102 are closed.

[0112] Therefore, the driving member 30 is preferably a cylinder driving member, which is connected to a gas pump through the gas inlet and outlet 3012 and introduces a certain amount of gas into the cylinder sleeve 301, and then closes the exhaust valve of the gas pump used, so as to drive the first cutter head 101 and the second cutter head 102 to close to cut the thread tail, and correspondingly, the first thread clamping block 201 and the second thread clamping block 202 are synchronously closed to clamp the cut thread tail.

[0113] In reverse operation, a certain amount of gas is introduced into the cylinder sleeve 301 through the gas inlet and outlet 3012, so as to drive the first cutter head 101 and the second cutter head 102 to open in reverse, and correspondingly, the first thread clamping block 201 and the second thread clamping block 202 are synchronously opened in reverse to release the cut thread tail.

[0114] For the above-mentioned driving member 30, the structure components are less, so that the cost is low.

[0115] It should be further supplemented that, in specific implementation, according to one embodiment of the application, the driving member 30 further comprises a reset spring 303.

[0116] Wherein, the connecting port 3011 is provided with an inner edge 3013 around the inner ring; the outer wall of the front end of the cylinder piston 302 is inwardly cut to form a concave step 3022; the front end of the reset spring 303 is abutted to the inner edge 3013, and the rear end is abutted to the concave step 3022.

[0117] Thus, in the above reverse operation, the exhaust valve of the air pump used is opened, and under the pressure difference between the inside and outside of the cylinder sleeve 301, the reset spring 303 will automatically reset to push the cylinder piston 302 backward to make it slide backward in the cylinder sleeve 301, so as to drive the gas in the cylinder sleeve 301 to be automatically discharged through the gas inlet and outlet 3012. At this time, under the reaction force of the pressing spring 106, the first cutter head 101 and the second cutter head 102 can be driven to open reversely, and correspondingly, the first wire clamping block 201 and the second wire clamping block 202 can be synchronously opened reversely to release the cut wire tail.

[0118] Further need to be supplemented that, in specific implementation, according to an embodiment of the present application, the application also includes a locking piece for fixing the wire cutter 10 and the cylinder sleeve 301; the locking piece includes a fixed insertion rod 3041 and an R-shaped locking pin 3042.

[0119] A through hole 1031 is formed in the middle of the rotating shaft 103, and two fixed holes 3014 corresponding to the two sides of the through hole 1031 are formed in the outer wall of the cylinder sleeve 301 close to the connecting port 3011. The fixed insertion rod 3041 passes through the through hole 1031 and the two fixed holes 3014, and a locking hole 30411 located outside the cylinder sleeve 301 is formed at the end of the fixed insertion rod 3041. The R-shaped locking pin 3042 can be detachably inserted into the locking hole 30411 to lock and fix the wire cutter 10 and the cylinder sleeve 301.

[0120] Thus, when the wire cutter 10 is worn out or damaged, the R-shaped locking pin 3042 is pulled out, and the fixed insertion rod 3041 is pulled out from the through hole 1031 and the two fixed holes 3014, so as to facilitate the replacement of the wire cutter 10. Correspondingly, since the wire clamping width of the wire clamp 20 is slightly larger, the service life of the wire clamp 20 is longer than that of the wire cutter 10. Therefore, when the first wire clamping block 201 and the second wire clamping block 202 are detachably connected to the wire cutter 10, it is convenient to replace and install them on a new wire cutter 10 for continuous use, so that the overall use effect of the application can be optimized.

[0121] Further need to be supplemented that, in specific implementation, according to an embodiment of the present application, a sealing cover 305 is threadedly connected to the inside of the rear gas inlet and outlet 3012 of the cylinder sleeve 301, and a sealing ring A 306 is sleeved on the outer wall of the sealing cover 305.

[0122] Meanwhile, in the technical solution, the outer wall of the cylinder piston 302 is also sleeved with a sealing ring B 307 abutting against the inner wall of the cylinder sleeve 301, so that the air charging space formed between the rear part of the cylinder sleeve 301 and the rear end surface of the cylinder piston 302 has good sealing performance and good air leakage prevention effect, and when the sealing cover 305 is disassembled, the reset spring 303 and the cylinder piston 302 are conveniently assembled into the cylinder sleeve 301, so that the application is convenient to disassemble and assemble for use.
