Description

Technical Field

[0001] The utility model relates to the technical field of cable stripping equipment, in particular to a clamping component of a wire stripping machine. Background Art

[0002] During the power maintenance process, it is often necessary to use a wire stripper to complete the cutting of the sheath of overhead cables in order to check the internal structure of the cable or make wire connections. For example, a cable stripper disclosed in CN114243584A demonstrates the application of such equipment. This type of equipment usually integrates three major components, namely a rotating component, a clamping component and a cutting component, wherein the rotating component is equipped with a handle for the operator to hold. The operation process involves putting the cable on the inner circumference of the rotating component, the clamping component gently clamps the cable, and the cutting component is located on the side of the cable. During operation, the rotating component rotates to drive the clamping component to move and rotate smoothly along the axial direction of the cable, and simultaneously implement the cutting action to strip the cable sheath.

[0003] In order to ensure the stable positioning of the cable during the stripping process, the clamping surface of the clamping assembly is often designed as an inwardly recessed wire clamping groove, and a series of spaced ridges are set on the groove wall along the cable axis to increase friction and prevent the equipment from slipping during operation.

[0004] In the prior art, these ridges are mostly traditional straight bar structures and are usually arranged perpendicular to the cable axis. Although this structure effectively improves the anti-slip performance, it also increases the sliding friction, resulting in greater resistance when the wire stripping machine moves along the cable, affecting the stripping efficiency and smoothness of operation.

DETAILED DESCRIPTION

[0053] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] like Figure 2 As shown, a clamping assembly of a wire stripping machine of the utility model includes a linear slide 1 and a cable box 2.

[0055] Figure 1 The structure of the wire stripping machine is shown. When the clamping assembly is used in the wire stripping machine, such as Figure 1 As shown, when the linear slide 1 is set horizontally.

[0056] The cable box 2 is fixedly arranged at the bottom of the linear slide 1, and the side end of the cable box 2 is used to fix the connection with the rotating component 3. The linear slide 1 has two clamping ends 101, and one of the clamping ends 101 is used to fix the connection with the cutting component 4. The rotating component 3 and the cutting component 4 adopt any one of the prior arts, such as a cable stripper disclosed in CN114243584A, which has a rotating box body and a stripping mechanism. The rotating component 3 can adopt the structural design of the rotating box body, and the cutting component 4 can adopt the structural design of the stripping mechanism. The specific structure and working principle will not be repeated here.

[0057] To facilitate the positioning of the cable, in the above structure, the opposite ends of the two clamping ends 101 are recessed inward to form a wire clamping groove 102 for clamping the cable. When stripping, the cable is located between the two clamping ends 101, and the two clamping ends 101 clamp the cable but do not clamp it tightly, ensuring that the clamping ends 101 and the cable can move relative to each other.

[0058] On the groove wall of the clamping groove 102, a continuous convex rib 103 is fixedly arranged along the axial direction of the cable. The rib 103 forms a spiral structure along the axial direction of the cable to simulate the function of a thread. Figure 6As shown, the distance between the upper end of the rib 103 and the rotating assembly 3 is smaller than the distance between the lower end of the rib 103 and the rotating assembly 3. The distribution of the rib 103 is similar to the spiral pattern on a bolt or a screw. Specifically, it is arranged around the groove wall of the clamping groove 102. Therefore, the pattern of the spiral pattern is as follows: Figure 7 The square spring shape is shown. At the same time, on the groove wall, the ribs 103 are not arranged in a straight line, but are wound up according to a certain pitch (i.e., the longitudinal distance between two adjacent circles of ribs 103) and a spiral angle. For example, the height of the ribs 103 is 2-5 mm, the width is 3-7 mm, and the distance between adjacent ribs 103 is 1.5 to 2.5 times the width of the ribs 103.

[0059] The spiral structure simulates the operating principle of the thread to guide the movement direction of the clamping component and reduce the resistance, thereby effectively reducing the resistance of the wire stripping machine moving along the cable, thereby improving the efficiency of the cable stripping operation and the smoothness of the operation.

[0060] The linear slide 1 is used to drive the two clamping ends 101 to perform clamping or releasing actions. Specifically, the linear slide 1 includes a base 11, left and right spiral screws 12, a motor 13, a first slider 14 and a second slider 15, wherein the base 11 is fixedly arranged on the top of the cable box 2; the left and right spiral screws 12 are horizontally arranged and rotatably arranged on the top of the base 11, the left and right spiral screws 12 are perpendicular to the axial direction of the cable, and one end of the left and right spiral screws 12 is fixedly connected to the output end of the motor 13; the motor 13 is fixedly arranged on the side end of the base 11; the first slider 14 and the second slider 15 are slidably arranged on the top of the base 11, the left and right spiral screws 12 pass through the first slider 14 and the second slider 15, the first slider 14 is screwed on the left-handed thread of the left and right spiral screws 12, and the second slider 15 is screwed on the right-handed thread of the left and right spiral screws 12; the wire clamping groove 102 is arranged on the opposite ends of the first slider 14 and the second slider 15; the cutting assembly 4 is arranged at the bottom of the end of the first slider 14 away from the rotating assembly 3.

[0061] In the above structure, a threaded hole 105 is provided at the position corresponding to the left and right screw rods 12 on the first slider 14 and the second slider 15. The left and right screw rods 12 pass through the corresponding threaded holes 105 and are screwed. Through this structure, the left and right screw rods 12 drive the first slider 14 and the second slider 15 to move.

[0062] When the motor 13 is powered on, its output end drives the left and right screw rods 12 to rotate, and the left and right screw rods 12 drive the first slider 14 and the second slider 15 to move synchronously to clamp and release. When the first slider 14 moves, it drives the cutting assembly 4 to move synchronously.

[0063] In the structural design of the linear slide, in order to improve the positioning effect of the clamping components, such as Figure 1As shown, the first slider 14 and the second slider 15 extend outwardly in the horizontal direction at one end away from the rotating component 3 and extend out of the end of the base 11 away from the rotating component 3, so that the overall length of the first slider 14 and the second slider 15 is longer, and the length of the cable that can be clamped is longer, thereby improving the positioning effect. In addition, the end of the first slider 14 extending outward is provided with an oil tool mounting hole 104 along the axial direction of the left and right spiral screws 12, and the tool mounting hole 104 is used to install a tool, which is a component in the cutting component 4, such as the stripping knife disclosed in CN114243584A.

[0064] In the structural design of the linear slide, the linear slide 1 also includes a guide rod 16, wherein the guide rod 16 is parallel to the left and right spiral screws 12, and one guide rod 16 is arranged on each side of the left and right spiral screws 12; the two guide rods 16 are fixedly arranged on the top of the base 11, and the two guide rods 16 pass through the first slider 14 and the second slider 15 and are slidably connected; specifically, a light hole 106 is arranged at the position corresponding to the guide rod 16 on the first slider 14 and the second slider 15, and the guide rod 16 passes through the corresponding light hole 106 and is slidably connected; when the left and right spiral screws 12 drive the first slider 14 and the second slider 15 to move, the guide rod 16 slides along the light hole 106.

[0065] In the structural design of the linear slide, the linear slide 1 also includes a handle 17, wherein the handle 17 is detachably arranged on one end of the left and right spiral screws 12 away from the motor 13; specifically, a countersunk hole 107 is arranged at one end of the handle 17, wherein one end of the left and right spiral screws 12 is embedded in the countersunk hole 107 and connected by bolt fixing; the end of the handle 17 away from the countersunk hole 107 is in a ring shape; when the clamping assembly is accidentally locked, the handle 17 is installed on the left and right spiral screws 12, and the left and right spiral screws 12 are rotated by the handle 17 to achieve unlocking, so as to facilitate the separation of the wire stripping machine from the cable, and then facilitate the maintenance of the wire stripping machine.

[0066] In the structural design of the linear slide, the linear slide 1 also includes a shield 18, wherein the shield 18 is sleeved on the outside of the motor 13 and fixedly arranged on the end of the base 11 away from the handle 17; at the same time, a first wiring hole 201 is provided on the end of the cable box 2 close to the rotating component 3, and a second wiring hole 202 is provided on the end of the cable box 2 close to the shield 18, and the second wiring hole 202 is connected to the interior of the shield 18; a third wiring hole 203 is provided on the side of the shield 18 close to the cutting component 4; through this structure, it is convenient to hide the power supply cable of the motor 13, so that the cable does not leak out and prevent entanglement.

[0067] The method of using the clamping assembly of a wire stripping machine of the utility model is as follows:

[0068] The linear slide 1 is used to drive the two clamping ends 101 to perform clamping or loosening actions; when the output shaft of the motor 13 rotates forward, the output end of the motor 13 drives the left and right spiral screws 12 to rotate forward, and the left and right spiral screws 12 drive the first slider 14 and the second slider 15 to perform a clamping action. After clamping, the tool in the tool mounting hole 104 cuts into the outer skin of the cable; when the output end of the motor 13 reverses, the left and right spiral screws 12 drive the first slider 14 and the second slider 15 to loosen the action.

[0069] The above description is only a preferred embodiment of the present invention and is 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.
