Description

Technical Field

[0001] This utility model relates to the field of suspended machining technology, specifically a suspended drilling tool. Background Technology

[0002] Suspension strings are an important component of overhead transmission lines. They are mainly used to support the weight of conductors or split conductors. Suspension strings are frequently used during cable laying to make the cable laying more convenient and reasonable. During the fabrication of suspension strings, holes need to be drilled to facilitate the subsequent suspension binding of the cables.

[0003] Currently, existing pendant drilling fixtures typically place the pendant on a machining base when drilling, and the machining base has a V-groove to limit the pendant. However, the stability of limiting the pendant by the V-groove is relatively poor, which can easily cause the pendant to wobble during the subsequent drilling process and cause the hole drilled by the drilling fixture to be tilted, thus reducing the processing quality of the pendant. Utility Model Content

A horizontal plate 3 is fixedly connected to the inner surface of the mounting plate 101, a sliding groove 303 is opened in the middle of the horizontal plate 3, and a moving block 4 is provided below the horizontal plate 3. A mounting groove 405 is opened inside the moving block 4, and a sliding plate 403 is slidably arranged inside the mounting groove 405. A spring 404 is fixedly connected to the upper end of the sliding plate 403, and the upper end of the spring 404 is fixedly connected to the inner wall of the mounting groove 405. A pressure plate 401 is fixedly connected to the inner surface of the sliding plate 403, and a rubber block 402 is provided below the pressure plate 401. One side surface of the rubber block 402 is fixedly connected to the inner surface of the sliding plate 403. A mounting screw 102 is provided on the outer side of the mounting plate 101, and the mounting plate 101 is fixedly mounted on the upper surface of the processing base 1 by the mounting screw 102.

[0019] As a technical optimization of this utility model, an arc-shaped groove 4021 is provided on the other side surface of the rubber block 402, and the arc-shaped groove 4021 is a quarter circle structure. The arc-shaped groove 4021 can make the suspension contact the rubber block 402 more fully, and can further improve the limiting stability of the suspension.

[0020] As a technical optimization of this utility model, a sliding rod 106 is fixedly connected to the upper surface of the moving block 4, and the side surface of the sliding rod 106 is slidably connected to the sliding groove 303. The upper end of the sliding rod 106 is provided with a driving mechanism. The sliding rod 106 can limit the moving block 4, thereby improving the stability of the moving block 4 and making the moving block 4 move more smoothly.

[0021] As a technical optimization of this utility model, the driving mechanism includes a driving screw 103, which is threadedly connected to the mounting plate 101. One end of the driving screw 103 is rotatably connected to a pushing block 105, and the lower surface of the pushing block 105 is fixedly connected to the upper end of the sliding rod 106. The other end of the driving screw 103 is fixedly connected to a handle 104, which facilitates the movement of the moving block 4 and can fix the suspension.

[0022] As a technical optimization of this utility model, a support plate 203 is provided above the mounting plate 101, and a drive motor 202 is fixedly connected to the upper surface of the support plate 203. A drill bit 204 is fixedly connected to the lower end of the drive motor 202 through the support plate 203. A connecting plate 201 is fixedly connected to the other end of the support plate 203, and hydraulic cylinders 2 are fixedly connected to the lower surfaces of both ends of the connecting plate 201.

[0023] As a technical optimization of this utility model, the inside of the horizontal plate 3 is symmetrically provided with groove I 301, and the groove I 301 is located on both sides of the slide groove 303. The inside of the pressure plate 401 is symmetrically provided with groove II 4011, and the groove II 4011 is aligned with the groove I 301. The grooves I 301 and the groove II 4011 prevent the horizontal plate 3 and the pressure plate 401 from limiting the drill bit 204, thus preventing the drill bit 204 from drilling the suspended part.

[0024] In use, the first step is to pass one end of the pendant through the V-shaped groove on the upper surface of the processing base 1 and place the pendant inside the V-shaped groove. Then, the operator simultaneously rotates the drive screw 103 in the drive mechanism through the handle 104. At this time, the drive screw 103 will push the push block 105 to move relative to it. Therefore, the push block 105 moves relative to the moving block 4 through the handle 104. The sliding plate 403 inside the moving block 4 is pushed by the elastic force of the spring 404 to keep the lower end of the sliding plate 403 in contact with the inner wall of the V-shaped groove. Then, the rubber block 402 on the inner surface of the sliding plate 403 will clamp and fix the pendant. At the same time, the pressure plate 401 will be clipped above the pendant. Then, the operator can start the hydraulic cylinder 2 and the drive motor 202 at the same time. At this time, the drill bit 204 at the lower end of the drive motor 202 will pass through the groove I 301 and the pressure plate 401 to drill a hole in the pendant.
