Description

Technical Field

[0001] The invention relates to the field of cable installation, in particular to an auxiliary stripping device for the end of a connecting wire. Background Art

[0002] When connecting different cables, you need to first peel off the outer sheath of the cable end to expose the copper wire inside the cable. Since the cable sheath is tightly connected to the cable and is not easy to cut off, corresponding stripping tools or stripping devices are used to assist the stripping operation.

[0003] According to the patent document CN202410009140.9, an auxiliary stripping device for the end of a connecting wire is proposed. By operating the wire stripping control downward pressure component, the cutting knife direction control component is driven to move at an angle, so that the cutting knife direction control component controls the four transmission cutting components to be close to each other and fit on the wire, so that the wire cutting knife cuts into the skin of the wire. At this time, the wire stripping control downward pressure component continues to be applied with force. When the wire cutting knife reaches the maximum cutting depth, the semi-ring shielding plate can be rotated to drive the four wire cutting knives to rotate synchronously to complete the wire circumferential surface cutting operation. After cutting, the wire is pulled out again. At this time, the transmission gear and the transmission tooth plate are driven to engage and transmit by sliding the moving slider. At this time, the wire cutting knife is kept rotating ninety degrees, and then the circular cutting can be performed first, so that this method not only cuts the wire circumference, but also the cut ring sleeve can be cut axially during the wire extraction process, thereby improving the stripping efficiency.

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. Example

[0033] See also Figure 1 - Fig.10 As shown, an auxiliary stripping device for the end of a connecting line comprises a shell 1, a cover plate 20 is fixedly connected to the top of the shell 1, three groups of pillars 60 are fixedly connected to the inner wall of the shell 1, the top of the pillars 60 is fixedly connected to the bottom of the support plate 23, a pushing mechanism is arranged on the support plate 23, the pushing mechanism is used to drive the sliding frame 33 to move back and forth, the rear end of the sliding frame 33 is provided with a cutting mechanism, the cutting mechanism is used to drive the two groups of cutting knives 56 to approach each other when the cable end moves to the cutting knife 56, so as to complete the cutting of the outer skin of the cable end, and a discharging assembly is arranged inside the shell 1, and the discharging assembly is used to smoothly discharge the cut cable outer skin from the inside of the shell 1;

[0034] Furthermore, the pushing mechanism includes a driving wheel 22 and three sets of driven wheels 26, the bottom ends of the driving wheel 22 and the driven wheels 26 are fixedly connected with a connecting block 25, the connecting block 25 is rotatably connected to the support plate 23, the outer sides of the driving wheel 22 and the driven wheel 26 are sleeved with a belt 24, the connecting block 25 fixedly connected to the bottom end of the driving wheel 22 is fixedly connected to the output shaft of the servo motor 21, one side of the belt 24 is fixedly connected with a protrusion 27, the top end of the protrusion 27 is fixedly connected with a protrusion 28, and the top end of the protrusion 28 slides Connected to the inside of the transverse groove 37, the transverse groove 37 is opened at the bottom of the sliding frame 33, the left and right sides of the sliding frame 33 are fixedly connected with rectangular blocks 32, the rectangular blocks 32 are slidably connected to the sliding rod 57, the front and rear sides of the sliding rod 57 are fixedly connected to the inner wall of the shell 1, the middle part of the top of the sliding frame 33 is fixedly connected with a placement plate 34, the top of the placement plate 34 is U-shaped, the top of the placement plate 34 is fixedly connected with a rubber sheet 35, the front ends of the shell 1 and the cover plate 20 are respectively opened with a notch 61 and a long groove 63;

[0035] Through the structural design of the pushing mechanism, when stripping the cable, after placing the cable on the placement plate 34, the sliding frame 33 can be moved back and forth in the front and rear directions under the drive of the servo motor 21, so as to automatically send the cable end to the position of the cutting knife 56 for cutting, making the stripping operation more convenient. During operation, the servo motor 21 first drives the driving wheel 22 to rotate through the connecting block 25 at the bottom end of the driving wheel 22, and the driving wheel 22 drives the belt 24. The three sets of driven wheels 26 are used to support the belt 24. As the belt 24 moves, the protrusion 27 fixed on one side of the belt 24 will drive the protrusion 28 to move synchronously. Since the protrusion 27 is fixed on the outside of the belt 24, the protrusion 28 will not abut against the driving wheel 22 and the driven wheel 26 during the movement, and the top of the protrusion 28 slides inside the transverse groove 37. When the protrusion 28 is located at Figure 6When the convex column 28 moves to the position shown in the figure, it will abut against the inner wall of the transverse groove 37 and drive the sliding frame 33 to move forward. When the convex column 28 moves to the turning point at the front end of the support plate 23, the convex column 28 will move horizontally and slide along the transverse groove 37 again. At this time, the convex column 28 moves along the groove and no longer pushes the sliding frame 33 to move. The sliding frame 33 will also move forward to the maximum distance. At this time, the cable can be smoothly placed on the placement plate 34 through the notch 61 opened on the shell 1 and the long groove 63 opened on the cover plate 20 and clamped and fixed by the rubber sheet 35 fixed on the placement plate 34 ... When 8 moves to the turning point at the front end of the support plate 23 again, the movement of the protruding column 28 will drive the sliding frame 33 to move backward again until the sliding frame 33 moves to the maximum position. At this time, the rear end of the cable fixed on the placement plate 34 will be close to the cutting knife 56, thereby automatically sending the cable to the position of the cutting knife 56, so that the cutting knife 56 can cut off the outer skin of the cable end. The top of the placement plate 34 is U-shaped to facilitate the fixing of the cable. The left and right sides of the sliding frame 33 support the sliding frame 33 through the sliding of the rectangular block 32 on the sliding rod 57 to ensure the normal movement of the sliding frame 33.

[0036] Further, the cutting mechanism includes teeth 29, the teeth 29 are provided on one side of the belt 24, the rear end of the belt 24 is close to the connecting gear 38, the rear end of the connecting gear 38 is meshed with the rotating gear 48, the left and right sides of the bottom end of the rotating gear 48 are both rotatably connected with a connecting rod 47, the top end of the connecting rod 47 is rotatably connected with a fixed block 52, the fixed block 52 is inserted into the inside of the sleeve 45, the sleeve 45 is fixedly connected to the inner wall of the housing 1, and the top end of the fixed block 52 is fixedly connected with a support rod 4 6. A groove 53 is provided inside the support rod 46. Two groups of support springs 54 are fixedly connected to the inner wall of the groove 53. The support spring 54 is fixedly connected to a moving block 55. The moving block 55 is slidably connected inside the groove 53. The side of the moving block 55 away from the support spring 54 is fixedly connected to a cutting knife 56. The cutting knife 56 is semicircular in design. The bottom ends of the connecting gear 38 and the rotating gear 48 are both rotatably connected to the support column 39. The bottom end of the support column 39 is fixedly connected to the inner wall of the housing 1.

[0037] Furthermore, a reset gear 40 is fixedly connected to the top of the connecting gear 38, and the reset gear 40 is meshed with a reset rack 41. The reset rack 41 is slidably connected to a guide rod 42, and the left and right sides of the guide rod 42 are fixedly connected to the inner wall of the outer shell 1, and the left side of the reset rack 41 is fixedly connected to a reset spring 44, and the left side of the reset spring 44 is fixedly connected to the inner wall of the outer shell 1, and the reset spring 44 is sleeved on the outer side of the guide rod 42; wherein the guide rod 42 runs through the inside of the reset rack 41, and the guide rod 42 supports the reset rack 41 to ensure the stable movement of the reset rack 41 and the correct meshing of the reset gear 40.

[0038] The structural design of the cutting mechanism realizes that when the cable end moves to the position of the cutting knife 56, the cutting knife 56 can approach each other until the cable sheath is cut off, so that the cutting knife 56 can automatically cut the sheath of the cable end, and can smoothly separate the cut cable sheath from the cable when the sliding frame 33 moves backward. During operation, when the protruding column 28 drives the sliding frame 33 to move backward to the cutting knife 56, the protruding column 28 continues to move with the movement of the belt 24 but does not drive the sliding frame 33 to move. Since the teeth 29 are provided on one side of the belt 24, the teeth 29 can be engaged with the connecting gear 38 to drive it to rotate. After the connecting gear 38 The ends of the rotating gears 48 are kept in mesh with each other, thereby driving the rotating gears 48 to rotate. During the rotation of the rotating gears 48, the two sets of connecting rods 47 fixed at the bottom ends thereof will be pulled, and the top ends of the connecting rods 47 are rotatably connected with the fixing blocks 52. The fixing blocks 52 are inserted in the sleeves 45 and can only move in the left and right directions. Therefore, the connecting rods 47 can pull the fixing blocks 52 to move stably, and the supporting rods 46 fixed at the top ends of the fixing blocks 52 will also approach each other. The cutting knife 56 is fixed on the moving block 55, and the cutting knife 56 will first contact the outer skin of the cable end, and as the supporting rods 46 continue to move, the supporting springs 54 will be compressed, and the cutting knife 56 will continuously squeeze the outer skin of the cable end. The outer skin is finally cut off by pressing; in the process of the tooth 29 driving the connecting gear 38 to rotate, the reset gear 40 fixed on the top of the connecting gear 38 will rotate synchronously, and the reset gear 40 will keep meshing with the reset rack 41 to make the reset rack 41 move to the left. A reset spring 44 is fixed on the left side of the reset rack 41, and the reset spring 44 will be compressed. When the tooth 29 is no longer meshed with the connecting gear 38 as the belt 24 continues to move (at this time, the boss 28 moves to the turning point at the lower left end of the support plate 23, and the boss 28 can drive the sliding frame 33 to move forward as the belt 24 moves), the reset spring 44 will push the reset rack 41 to move, and the reset rack 41 can drive the reset rack 41 to move. The reverse rotation of the positioning gear 40 drives the connecting gear 38 to rotate in the reverse direction. The reverse rotation of the connecting gear 38 drives the rotating gear 48 to rotate, and the two sets of support rods 46 will move away from each other. Since the outer skin of the cable end has been cut off and separated from the cable by the cutting knife 56, and the two sets of support springs 54 are in a compressed state, they can only drive the moving block 55 to move when they return to their original length state, so the position of the cutting knife 56 can still be kept fixed. At this time, the cutting knife 56 can block the cut outer skin to prevent the outer skin from moving forward with the cable. The sliding frame 33 continues to move forward to separate the cable from the cut outer skin, and the cut outer skin can be smoothly peeled off the cable.

[0039] Further, the discharging assembly includes a through slot 49, which is provided on the rotating gear 48 and is designed in a trapezoidal shape. The bottom end of the rotating gear 48 does not contact the top end of the guide plate 50, and the bottom end of the guide plate 50 is fixedly connected to the inner wall of the housing 1. The bottom end of the guide plate 50 is aligned with the rectangular slot 58, and the rectangular slot 58 is provided at the bottom end of the housing 1.

[0040] Through the structural design of the discharge component, after the outer skin of the cable end is cut off, the cut outer skin will fall into the through groove 49 under the action of gravity and slide into the inside of the guide plate 50, and finally fall out of the shell 1 through the rectangular groove 58 on the bottom end of the shell 1, so as to avoid the accumulation of the cable outer skin inside the shell 1. During operation, a through groove 49 is provided on the rotating gear 48, and the through groove 49 is designed in a trapezoidal shape to guide the cable outer skin falling on the through groove 49 so that it can slide smoothly into the guide plate 50. When the outer skin of the cable end is separated from the cable, the rotating gear 48 is rotated to a suitable position at this time, so that the through groove 49 provided on the rotating gear 48 is located below the outer skin, and the outer skin can fall into the through groove 49 under the action of gravity, and fall out of the inside of the shell 1 through the rectangular groove 58 along the guide plate 50. When installing and fixing the shell 1, it is only necessary to ensure that the bottom end of the rectangular groove 58 is normally connected to the outside world.

[0041] Furthermore, a gasket 51 is fixedly connected to the top of the connecting rod 47, and the gasket 51 is made of rubber material;

[0042] During operation, a gasket 51 is fixed on the top of the connecting rod 47, and the gasket 51 is located between the bottom end of the fixing block 52 and the top of the connecting rod 47, so that the gasket 51 can prevent the connection between the connecting rod 47 and the fixing block 52 from abutting against the rotating gear 48 to reduce wear.

[0043] Furthermore, two sets of sliders 36 are fixedly connected to the bottom end of the sliding frame 33, and the sliders 36 are slidably connected inside the slide groove 30. The slide groove 30 is opened at the top end of the fixed plate 31, and the fixed plate 31 is fixedly connected to the top end of the support plate 23. The top end of the fixed plate 31 does not contact the bottom end of the sliding frame 33.

[0044] During operation, two sets of sliders 36 are fixed to the bottom of the sliding frame 33. When the sliding frame 33 moves, the sliders 36 slide on the slide grooves 30, thereby providing support for the bottom of the sliding frame 33, so that the sliding frame 33 can move more smoothly.

[0045] Furthermore, a motor housing 59 is sleeved on the outer side of the servo motor 21, and the bottom end of the motor housing 59 is fixedly connected to the inner wall of the outer shell 1. A heat dissipation groove is opened on the motor housing 59, and the heat dissipation groove runs through the motor housing 59 and the left and right sides of the outer shell 1;

[0046] During operation, the motor housing 59 is used to support and fix the servo motor 21 , and a heat dissipation groove is also provided on the motor housing 59 to ensure normal heat dissipation of the servo motor 21 and normal flow of air inside the housing 1 . Example
