[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-10The embodiment of the present invention provides a high-precision cable insulation sheath cutting and sampling tool, comprising a housing 1, a sampling cutter 101 arranged in the housing 1, and a smearing mechanism, wherein the smearing mechanism comprises a bearing plate 2, a gear ring 23, and a sliding frame 3: the bearing plate 2 is slidably connected to the housing 1 along the axial direction of the cable, a first clamp 21 is fixedly connected to the bearing plate 2 and a second clamp 22 is slidably connected to the first clamp 21 and a second clamp 22 is slidably connected to the first clamp 21 and a second clamp 22 is used to clamp the cable; the gear ring 23 is rotatably connected to the first clamp 21, and a movable connection is formed on the gear ring 23.

[0022] The transmission assembly 4 includes a rotating rod 41, a gear 42, a second rack 43 and a third rack 44. The rotating rod 41 is rotatably connected to the gear ring 23, and the smear member 201 is fixedly connected to the rotating rod 41; the gear 42 is coaxially fixedly connected to the rotating rod 41; the second rack 43 is fixedly connected to the bottom of the first straight tooth; the third rack 44 is fixedly connected to the top of the first straight tooth, and also includes a first locking assembly 5, the first locking assembly 5 includes a fixed plate 51, a connecting rod 52, a first elastic member 53 and two U-shaped abutment rods 54, the fixed plate 51 is fixedly connected to the gear ring 23, the fixed plate A triangular prism-shaped abutment block is slidably connected to 51, and the abutment block has a first abutment surface and a second abutment surface; a connecting rod 52 is fixedly connected to the abutment block, and the connecting rod 52 passes through the fixed plate 51 and can be plugged into and matched with any one of the two sockets opened on the rotating rod 41; the first elastic member 53 drives the abutment block to slide during the process of restoring the deformation; the two abutment rods 54 are respectively fixedly connected to the second rack 43 and the third rack 44. Specifically, the first elastic member 53 includes a first spring, one end of the first spring is fixedly connected to the fixed plate 51, and the other end is fixedly connected to the connecting rod 52.

[0023] Working principle: In order to improve the accuracy of cable cutting and sampling, the operator will choose to apply some cutting oil on the cable sampling part for some cables with harder cable surface. In this way, the operator first clamps the cable by using the first clamp 21 and the second clamp 22 to make the cable cutting and sampling part be aligned with the smearing piece 201, and then starts the first motor. The output shaft of the first motor is coaxially fixedly connected with the first screw 14 so that the first screw 14 rotates. The rotation of the first screw 14 drives the supporting plate 2 to slide relative to the casing 1 along the length direction of the cable. The first clamp 21 and the second clamp 22 on the supporting plate 2 clamp and pull the cable to move synchronously. In this process, the first clamp 21 will drive the sliding frame 3 to move. The sliding frame 3 slides vertically relative to the first clamp 21, and the sliding frame 3 slides relative to the shell along the inclined groove 11 of the shell.

[0024] First, the abutment rod 54 on the second rack 43 will abut against the first abutment surface of the abutment block, so that the abutment block can drive the connecting rod 52 to move, and the movement of the connecting rod 52 is separated from the insertion hole of the rotating rod 41, and then the second rack 43 and the gear 42 are meshed to make the rotating rod 41 rotate, and then the rotation of the rotating rod 41 drives the smearing member 201 to rotate to the smearing station. Here, the second rack 43 and the gear 42 cooperate to drive the rotating rod 41 to rotate half a circle. During the meshing process of the second rack 43 and the gear 42, When the abutment rod 54 ends its abutment with the abutment block, the first spring drives the connecting rod 52 to move, but the end of the connecting rod 52 inserted into the socket is not aligned with the other socket, so that the rotating rod 41 continues to rotate and the connecting rod 52 has a tendency to be inserted into the socket, until the other socket of the rotating rod 41 is aligned with the insertion end of the connecting rod 52, the first spring drives the connecting rod 52 to be inserted into the socket, thereby completing the fixed locking of the rotating rod 41 relative to the ring gear 23, and at the same time the second rack 43 also ends its meshing cooperation with the gear 42.

[0025] Then, as the bearing plate 2 continues to slide, the sliding frame 3 further slides downward relative to the first clamp 21, and the first rack 31 meshes with the gear ring 23. During this process, the first rack 31 drives the gear ring 23 to rotate relative to the first clamp 21 (the rotation direction of the gear ring 23 is coaxial with the cable), and then the smearing member 201 on the gear ring 23 smears the cutting sample of the cable with the rotation of the gear ring 23. Since the rotating rod 41 is plugged into the connecting rod 52 and the socket, the smearing member 201 will not be affected by the friction between the cable and the gear ring 23 and will not change its angle relative to the gear ring 23. After the gear ring 23 rotates one circle, the smearing member 201 will not change its angle relative to the gear ring 23. 201 also completes one week of cutting oil application to the cable. As the first rack 31 ends its meshing cooperation with the gear ring 23, the abutment rod 54 on the third rack 44 abuts against the first abutment surface of the abutment block, causing the connecting rod 52 to slide out of the engagement with the socket on the rotating rod 41. The meshing cooperation of the third rack 44 and the gear 42 drives the smearing member 201 to disengage from the smearing station. During the meshing cooperation of the third rack 44 and the gear 42, the abutment rod 54 ends its abutment cooperation with the abutment block, but until the socket on the rotating rod 41 is aligned with the insertion end of the connecting rod 52, the connecting rod 52 is inserted into the socket of the rotating rod 41 under the elastic force of the first spring to fix the smearing member 201.

[0026] Finally, the first clamp 21 releases the clamping of the cable, and the second clamp 22 continues to clamp the cable. The first motor is stopped and then the second motor is started. The output shaft of the second motor rotates to drive the guide rod 16 to rotate, and then the guide rod 16 drives the second lead screw 15 to rotate. The rotation of the second lead screw 15 allows the second clamp 22 to slide relative to the supporting plate 2. The movement of the second clamp 22 can drive the cable to move further, so that the cable portion coated with cutting oil is aligned with the sample preparation tool 101 in the casing 1. The clamp at the end of the casing 1 clamps the cable. In addition, the first clamp 21 continues to clamp the cable, and the cable is cut and sampled by the sample preparation tool 101. Since the cutting oil is coated on the cable, the sample preparation tool 101 makes it easier to cut the cable and the cutting accuracy is higher. After the sample preparation tool 101 finishes cutting and sampling the cable, the clamp at the end of the casing 1 is released from the first clamp 21. To clamp the cable, the output shaft of the second motor is reversed to make the second clamp 22 slide relative to the supporting plate 2, so that the second clamp 22 clamps the cable and retracts, and then the second motor is turned off and the first motor is started. The output shaft of the first motor is reversed to make the first screw 14 rotate and the supporting plate 2 slide relative to the casing 1. During the resetting and sliding process of the supporting plate 2, the abutment rod 54 of the third rack 44 abuts against the second abutment surface of the abutment block, so that the third rack 44 can mesh with the gear 42 and move upward relative to the first clamp 21. After the third rack 44 finishes mating with the gear 42, the first rack 31 meshes with the gear ring 23. Finally, the abutment rod 54 on the second rack 43 cooperates with the second abutment surface of the abutment block, so that the second rack 43 can also cooperate with the gear 42 and move upward relative to the first clamp 21. In this way, the first rack 31, the second rack 43 and the third rack 44 have all completed the resetting. When the first clamp 21 and the second clamp 22 pull the cable to move, the smearing member 201 can stably apply cutting oil to the cable under the clamping action of the first clamp 21 and the second clamp 22 .

[0027] Compared with the prior art, the present invention provides a high-precision cable insulation cutting and sampling tool, which clamps the cable by the first clamp 21 and the second clamp 22. The first clamp 21 and the second clamp 22 also pull the cable during the sliding process of the supporting plate 2 relative to the casing 1. In this process, the cooperation between the rack and the gear ring 23 enables the application member 201 to apply cutting oil to the cut part of the cable, and then the first clamp 21 contacts and clamps, and the second clamp 22 slides relative to the supporting plate 2 to drive the cable to move so that the application part moves to the sampling tool 101 in the casing 1 for cutting and sampling. In this way, when the first clamp 21 and the second clamp 22 clamp the cable and pull the cable to move, the application member 201 can apply cutting oil to the cut part of the cable, so that the application can be uniform and will not prolong the sampling work time. In addition, applying cutting oil can significantly improve the cutting accuracy.

[0028] Among them, the first clamp 21 and the clamp are both three-jaw chucks, which can clamp and fix cables of different sizes, and the driving of each jaw of the three-jaw chuck to clamp the cable can be manually driven or driven by a motor.

[0029] In another technical solution of the present invention, the first rack 31 is horizontally slidably connected to the sliding frame 3, and also includes a second locking assembly, which includes a first wedge block 311, a push rod 12, a second elastic member 32, a second wedge block 33, a third elastic member 34 and an inclined rod 13. The first wedge block 311 is fixedly connected to the first straight tooth; the push rod 12 is fixedly connected to the housing 1, and the push rod 12 is in abutment with the first wedge block 311; the second elastic member 32 drives the first rack 31 to slide horizontally during the process of restoring the deformation; the second wedge block 33 is slidably connected to the sliding frame 3, and the second wedge block 33 is relative to the sliding stroke of the sliding frame 3. It has a locking position that can be engaged with the slot 312 opened on the first rack 31, and the second wedge block 33 is fixedly connected to the connecting rod 331; the third elastic member 34 drives the second wedge block 33 to slide to the locking position during the process of restoring the deformation; the inclined rod 13 is fixedly connected to the casing 1, and the inclined rod 13 is abutted against the connecting rod 52. Specifically, the second elastic member 32 includes a second spring, one end of the second spring is fixedly connected to the sliding frame 3, and the other end is fixedly connected to the first rack 31; the third elastic member 34 includes a third spring, one end of the third spring is fixedly connected to the sliding frame 3, and the other end is fixedly connected to the second wedge block 33.

[0030] The first rack 31 is pressed against the locking plate 312 to secure the locking cam 33. The second rack 31 is pressed against the locking plate 312 to secure the locking cam 33. The locking cam 33 is pressed against the locking plate 312 to secure the locking cam 33. 1 drives the sliding frame 3 to move, but the first rack 31 does not need to be meshed with the gear ring 23, and the second rack 43 and the third rack 44 do not need to be meshed with the gear 42. When the supporting plate 2 is about to be reset, the connecting rod 331 on the second wedge block 33 abuts against the inclined rod 13, so that the connecting rod 331 drives the second wedge block 33 to move, and then the second wedge block 33 is separated from the slot 312, and the first rack 31 is reset by the elastic force of the first spring. In this way, during the reset and sliding process of the supporting plate 2, the first rack 31 does not need to be meshed with the gear ring 23, and the second rack 43 and the third rack 44 do not need to be meshed with the gear 42, which can effectively reduce wear and tear, and also prevent the smearing member 201 from smearing the cable during the return process of the supporting plate 2.

[0031] Another technical solution provided by the present invention also includes a driving component, which includes a first reciprocating screw 61, a second reciprocating screw, a guide rod 62, a first ratchet pawl mechanism 63, a second ratchet pawl mechanism 64, a full gear 65 and a driving motor 6. The first reciprocating screw 61 and the guide rod 62 are both rotatably connected in the housing 1. The first ratchet pawl mechanism 63 is arranged on the first reciprocating screw 61, and the second ratchet pawl mechanism 64 is arranged on the guide rod 62. The full gear 65 is rotatably connected in the housing 1. The full gear 65 is respectively meshed with the ratchet of the first ratchet pawl mechanism 63 and the ratchet of the second ratchet pawl mechanism 64. The output shaft of the driving motor 6 is coaxially fixedly connected with the full gear 65. The second reciprocating screw is slidably connected to the guide rod 62. The first reciprocating screw 61 is threadedly connected to the bearing plate 2, and the second reciprocating screw is threadedly connected to the second clamping member. The driving motor The output shaft of 6 rotates clockwise or counterclockwise to drive the full gear 65 to rotate clockwise or counterclockwise. The rotation of the full gear 65 can drive the first ratchet of the first ratchet and pawl mechanism 63 and the second ratchet of the second ratchet pawl to rotate, but the first ratchet is affected by the first pawl and the second pawl is affected by the second pawl (for example, when the first ratchet is in contact with the first pawl, the rotation of the first ratchet can drive the first pawl and the first reciprocating screw 61 to rotate). The full gear 65 can drive the first reciprocating screw 61 to rotate clockwise, and the counterclockwise rotation of the full gear 65 can drive the guide rod 62 to rotate, and then the guide rod 62 can drive the second reciprocating screw to rotate. The rotation of the first reciprocating screw 61 can drive the supporting plate 2 to slide back and forth relative to the housing 1, and the rotation of the second reciprocating screw can drive the second clamp 22 to slide back and forth relative to the supporting plate 2, which can effectively reduce the equipment cost.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
