Description

Technical Field

[0001] This utility model relates to the field of pre-twisted wire processing technology, specifically to an electric device for grinding round heads of wire guards in power fittings. Background Technology

[0002] Pre-twisted wire, also known as protective wire, is primarily used to protect conductors and optical cables. Pre-twisted wire first appeared in the United States in the 1940s and 50s, initially as spiral pre-twisted wire for protection at stress concentration points and against electro-corrosion and arc damage in bare conductors. After years of development, pre-twisted wire fittings are now widely used in power transmission and distribution, fiber optic communication, electrified railways, cable television, construction, agriculture, and other fields. Pre-twisted wire is used in connecting fittings for overhead power conductors and overhead optical cables, including terminals, suspensions, and joints. For example, pre-twisted wire is used instead of aluminum tape for conductors in large-span double-string porcelain insulators; pre-twisted wire is also used when connecting optical cables to optical cables, and optical cable vibration dampers also use pre-twisted wire. Before using pre-twisted wire to protect conductors and optical cables, a grinding process is required to round the ends of the pre-twisted wire to prevent sharp edges from causing cuts to users.

[0003] Existing methods require manual handling to move the end of the pre-twisted wire to the grinding disc of the grinding machine. The high-speed rotation of the grinding disc rounds the pre-twisted wire. This manual operation involves repeated picking and dropping, which is time-consuming and labor-intensive, reducing the efficiency of pre-twisted wire processing. In particular, when manually rounding the pre-twisted wire, the worker's hand is close to the grinding end, increasing the risk of hand contact with the grinding disc and potential injury, posing a significant safety hazard. Therefore, an electric device for rounding the ends of power fitting protective wires is proposed to solve the aforementioned problems. Summary of the Invention

[0004] This utility model provides an electric device for grinding the rounding head of the wire guard of power fittings, aiming to solve the technical problem that the pre-twisted wire grinding process in related technologies requires manual operation, which involves reciprocating handling of the pre-twisted wire, which is time-consuming and labor-intensive, reducing the working efficiency of the pre-twisted wire.

[0005] This utility model discloses an electric device for grinding round heads of protective wires in power fittings, comprising an operating platform and a driver disposed at one end of the operating platform. A grinding head is mounted on the end of the driver facing the operating platform. A clamping unit is disposed on the operating platform, and the clamping unit includes two clamping rods located above the operating platform. Each of the two clamping rods has a positioning groove at its opposite end. A sliding rod is connected below the clamping rods.

[0006] The operating platform is equipped with a conveying unit located on the side of the clamping unit away from the driver. The conveying unit includes a mounting frame, and the interior of the mounting frame is equipped with a conveying roller. The conveying roller has multiple grooves for holding pre-twisted wire.

[0007] Preferably, the guide hole includes a first through hole and a second through hole connected end to end, the first through hole is arranged along the length direction of the operating platform, and the second through hole is inclined relative to the first through hole.

[0008] Preferably, the drive unit includes a telescopic device installed below the operating platform, the telescopic end of the telescopic device is connected to a sliding block, the sliding block has a limit groove, and the sliding rod is located in the limit groove.

[0009] Preferably, a guide bar is provided below the operating platform, and a guide groove corresponding to the guide bar is provided on the sliding block.

[0010] Preferably, a rubber pad is fixedly connected inside the positioning groove.

[0011] Preferably, the mounting frame has an internal receiving groove in a U-shape, and the mounting frame has an inlet and an outlet at the top and bottom, respectively, with the outlet corresponding to the positioning groove.

[0012] Preferably, the mounting frame is provided with a transmission unit, and the transmission roller is rotated through the transmission unit.

[0016] Beneficial effects:

[0017] 1. The conveying unit enables intermittent conveying of pre-twisted wires, ensuring that each pre-twisted wire has time to be rounded. It also allows for continuous operation of the pre-twisted wires. In conjunction with the clamping unit, the position of the pre-twisted wires can be limited, and the ends of the pre-twisted wires can be brought close to the grinding head for rounding.

[0030] The embodiments of this utility model are described in detail below, with examples of the embodiments shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0031] like Figures 1 to 8 As shown, the present invention provides an electric device for grinding a round head for a protective wire of an electrical fitting, comprising an operating platform 100 and a driver 200 disposed at one end of the operating platform 100. The driver 200 is a motor, and a fixing frame 201 is disposed below the driver 200. A grinding head 210 is fixedly mounted on the end of the driver 200 facing the operating platform 100. The grinding head 210 is circular, and a grinding groove 211 is formed on the grinding head 210. The grinding groove 211 is arc-shaped. More specifically, a cover is fixedly mounted on one end of the driver 200. The protective cover 220 on the grinding head 210 has a feed hole at the end away from the driver 200 to allow the pre-twisted wire to enter the protective cover 220 and contact the grinding head 210. The protective cover 220 prevents the grinding debris of the pre-twisted wire from splashing everywhere. The lower part of the protective cover 220 is connected to the discharge pipe 221, and the lower end of the discharge pipe 221 is provided with a collection box to collect the grinding debris. The operating platform 100 has a rectangular groove corresponding to the discharge pipe 221, which allows the discharge pipe 221 to extend downward into the collection box.

[0032] A clamping unit 300 is provided on the operating platform 100. The clamping unit 300 is located at one end of the operating platform 100 near the driver 200. The clamping unit 300 is used to fix the pre-twisted wire and push it to the grinding head 210. The clamping unit 300 includes two clamping rods 310 symmetrically arranged above the operating platform 100. Each clamping rod 310 has a positioning groove 311 at its opposite end, which corresponds to the feed hole. The two positioning grooves 311 combine to form a receiving cavity for defining the position of the pre-twisted wire. Specifically, a rubber pad is fixedly connected inside the positioning groove 311. The rubber pad can flexibly wrap the pre-twisted wire to avoid rigid contact between the clamping rod 310 and the pre-twisted wire, which would cause deformation of the pre-twisted wire. The clamping rods 310 are slidably arranged above the operating platform 100 to ensure the stability of the clamping rods 310 during left and right movement. The upper end of the positioning groove 311 has a chamfer 312, which facilitates the rapid entry of the pre-twisted wire into the positioning groove 311. A sliding rod 320 is fixedly connected below the clamping rod 310. The operating platform 100 is provided with a guide hole 110 that works with the sliding rod 320. A driving unit is provided between the two sliding rods 320 to enable relative movement between the two sliding rods 320.

[0033] The operating platform 100 is provided with a conveying unit 400. The conveying unit 400 is located on the side of the clamping unit 300 away from the driver 200. The conveying unit 400 is used to realize intermittent continuous transport of pre-twisted wire. The conveying unit 400 includes a mounting frame 410. The mounting frame 410 is provided with a conveying roller 420. The conveying roller 420 has multiple grooves 421 for holding the pre-twisted wire. The multiple grooves 421 are arranged in a ring array on the surface of the conveying roller 420.

[0034] Specifically, the conveying unit 400 enables intermittent conveying of the pre-twisted wire, ensuring that each pre-twisted wire has time to be rounded, and allows for continuous operation of the pre-twisted wire. In conjunction with the clamping unit 300, the position of the pre-twisted wire can be limited, and the end of the pre-twisted wire can be brought close to the grinding head 210 for rounding, thereby replacing manual operation and effectively improving the working efficiency of the pre-twisted wire rounding head.

[0035] like Figures 3 to 5 As shown, the guide hole 110 includes a first through hole 111 and a second through hole 112 connected end to end. The first through hole 111 is arranged along the length direction of the operating platform 100, and the second through hole 112 is inclined relative to the first through hole 111, and the second through hole 112 is inclined toward the edge of the operating platform 100.

[0036] The drive unit includes a telescopic device 140 fixedly installed below the operating platform 100. The telescopic device 140 is a cylinder, and a sliding block 130 is fixedly connected to the telescopic end of the telescopic device 140. A limit groove 131 is formed on the sliding block 130. The limit groove 131 is strip-shaped, and the sliding rod 320 is located in the limit groove 131. The limit groove 131 is set so that the position of the sliding rod 320 is limited while allowing the sliding rod 320 to move on the operating platform 100. In detail, a guide bar 120 is provided below the operating platform 100, and a guide groove corresponding to the guide bar 120 is formed on the sliding block 130. The cooperation between the guide bar 120 and the guide groove can support the sliding block 130 and ensure the stability of the sliding block 130 during movement.

[0037] Specifically, the telescopic device 140 drives the sliding rod 320 on the sliding block 130 to move. The two sliding rods 320 move in the two guide holes 110 respectively, so that the two clamping rods 310 move closer to each other, fixing and conveying the pre-twisted wire, thereby replacing manual handling and avoiding injury to the workers.

[0038] like Figure 2 As shown, the mounting frame 410 has an internal receiving groove 411, which is U-shaped to facilitate the positioning of the conveyor roller 420. The conveyor roller 420 and the receiving groove 411 are coaxially arranged. Specifically, a rotating shaft 422 is fixedly connected to the middle of the conveyor roller 420, and a support plate 411 is fixedly connected to one side of the mounting frame 410. The rotating shaft 422 can be rotatably mounted on the support plate 411 through bearings to support the conveyor roller 420 and ensure the stability of the conveyor roller 420 during rotation. The mounting frame 410 has an inlet 412 and an outlet 413 at the top and bottom, respectively. The inlet 412 and the outlet 413 are vertically aligned, and the outlet 413 corresponds to the positioning groove 311. Specifically, a guiding device is provided above the inlet 412 so that the pre-twisted wires are arranged one by one in the vertical direction, so that each pre-twisted wire can enter the groove 421 on the conveyor roller 420.

[0039] A transmission unit is provided on the mounting frame 410. The transmission unit enables the rotation of the conveyor roller 420. The transmission unit includes a driven gear 430 mounted on the conveyor roller 420. Specifically, a mounting shaft is fixedly connected to the conveyor roller 420, and the driven gear 430 is fixed on the mounting shaft. The driven gear 430 is coaxially arranged with the conveyor roller 420. One side of the driven gear 430 meshes with a driving gear 440 mounted on the mounting frame 410. A power unit 460, which works with the driving gear 440, is mounted on the side of the mounting frame 410 away from the driving gear 440. The power unit 460 is an electric motor, and the drive shaft of the power unit 460 passes through the mounting frame 410 and is fixedly connected to the driving gear 440.

[0040] The mounting bracket 410 has mounting plates 450 connected to the lower sides on the operating platform 100. The mounting plates 450 are fixed to the operating platform 100 by bolts. There is a gap between the two mounting plates 450 and they correspond to the discharge port 413. Specifically, the upper surface of the mounting plate 450 is set horizontally with the upper surface of the clamping rod 310 so that the pre-twisted wire can be directly located between the two positioning grooves 311 after falling from the conveyor roller 420.

[0041] Specifically, after the pre-twisted wire enters the mounting frame 410, the driven gear 430 and the driving gear 440 work together to drive the conveyor roller 420 to rotate, thereby achieving intermittent and continuous conveying of the pre-twisted wire and ensuring the continuity of the pre-twisted wire processing.

[0042] In another embodiment, the conveying unit 400 can be two sets, with the two sets of conveying units 400 arranged at intervals to support both ends of the pre-twisted wire and ensure the stability of the pre-twisted wire.

[0043] Working principle of this utility model:

[0044] The pre-twisted wires are arranged along the direction of the operating platform 100, with multiple pre-twisted wires arranged vertically. Under the action of gravity, the pre-twisted wires enter the groove 421 in the conveyor roller 420 from the feed port 412, and drive the conveyor roller 420 to rotate counterclockwise through the cooperation between the drive gear 440 and the driven gear 430, thereby transporting the pre-twisted wires.

[0045] When the pre-twisted wire is discharged from the discharge port 413 of the mounting frame 410, the front end of the pre-twisted wire is positioned between two positioning grooves 311 by the chamfer 312. The two positioning grooves 311 cooperate to support the pre-twisted wire. At this time, the pre-twisted wire will stay between the two positioning grooves 311. The sliding rod 320 is located in the middle of the second through hole 112. After the pre-twisted wire is positioned between the two positioning grooves 311, the telescopic device 140 starts to work. The telescopic rod on the telescopic device 140 causes the sliding block 130 to move, which in turn drives the clamping rod 310 to move towards the driver 200. The sliding rod 320 moves towards the first through hole 111 in the second through hole 112, so that the two clamping rods 310 are relatively close, thereby clamping the pre-twisted wire.

[0046] When the sliding rod 320 moves from the second through hole 112 into the first through hole 111, the pre-twisted wire is completely clamped. The sliding rod 320 continues to move in the first through hole 111, causing one end of the pre-twisted wire to move toward the grinding groove 211 of the grinding head 210. The driver 200 starts to drive the grinding head 210 to rotate, thereby rounding the end of the pre-twisted wire.

[0047] After the pre-twisted wire ends are rounded, the clamping rod 310 retracts under the action of the telescopic device 140, and the sliding rod 320 moves again through the telescopic device 140. After being located at the tail end of the second through hole 112, the distance between the two clamping rods 310 is greater than the radial distance of the pre-twisted wire, causing the pre-twisted wire to fall off the two clamping rods 310. This process is repeated to facilitate the continuous rounding of the pre-twisted wire ends.
