Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a cable joint drilling tool. Background Technology

[0002] The cable joint is a key load-bearing component in a lifting system used to connect the lifting device and the wire rope. It has a hook structure at the head and a tapered cavity in the middle to fix the end of the wire rope. The plug serves as a sealing and auxiliary fixing component at the port of the cable joint. It is installed at the connection port between the cable joint and the wire rope. It is used to seal the cavity opening to prevent leakage of the filling medium or intrusion of external impurities, and also helps to strengthen the connection stability between the wire rope and the cable joint.

[0003] During the production of cable sections, holes need to be pre-drilled at the tail end to accommodate subsequent assembly requirements. Pre-drilling clamping and fixing are crucial for ensuring drilling accuracy. Due to the irregular structure of the cable section, traditional clamping fixtures have significant drawbacks: conventional clamps are difficult to adapt to the irregular shape of the cable section, and simple chucks or manual tightening can easily lead to unstable fixing. During drilling, the cable section undergoes slight displacement under cutting forces, directly causing hole position deviations.

[0004] Therefore, the inventors believe that designing a drilling fixture that adapts to irregularly shaped cable joints and combines precise positioning and stable clamping functions to solve the problem of insufficient drilling accuracy caused by traditional clamping methods is a technical problem that needs to be solved in the field of hoisting equipment technology.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] See Figures 1-6 To address the problems mentioned in the background section, this utility model provides a cable joint drilling tool to solve the aforementioned technical problems. The technical solution is as follows: A cable joint drilling fixture includes: a base plate 110, a vertical plate 120, a side plate 130, a positioning unit, a movable pressure plate 170, a bolt 160, and a nut 161; The side plate 130 is vertically fixed to the base plate 110; the upright plate 120 is vertically fixed to the base plate 110 and one side is fixedly connected to the side plate 130; the bolt 160 is vertically fixed to the top surface of the upright plate 120, and the tail of the bolt 160 is set upward. The positioning unit includes a fixed jaw block 140 fixed on the upright plate 120 and a movable jaw block 150 that slides horizontally on the side plate 130; the movable jaw block 150 can slide relative to the fixed jaw block 140. The movable pressure plate 170 slides through the bolt 160, and the movable pressure plate 170 has a first inclined surface 171 on both sides; the threaded section at the tail of the bolt 160 is connected to the nut 161. The movable jaw block 150 has a second inclined surface 151 that slides in cooperation with the first inclined surface 171 on one side near the movable pressure plate 170.

[0017] In this embodiment, the positioning unit includes two sets, which are symmetrically located on both sides of the movable pressure plate 150.

[0018] In this embodiment, a V-groove 152 is provided on the side of the movable jaw block 150 away from the movable pressure plate 170; the V-groove 152 on the side of the movable jaw block 150 can adapt to the irregular contour (such as conical or cylindrical) of the cable joint tail, increase the clamping contact area, improve clamping stability, and prevent the cable joint tail from slipping.

[0019] In this embodiment, a horizontal slide rail 131 is provided on the side plate 130, and a slider 153 is fixed on the back of the movable jaw block 150. The slider 153 is slidably connected to the horizontal slide rail 131. A limiting plate 154 is fixed at the end of the slider 153, and the limiting plate 154 is located outside the horizontal slide rail 131.

[0020] In this embodiment, the base plate 110 is provided with a limiting groove 111 that matches the shape and size of the head of the cable joint 200.

[0021] In this embodiment, a washer 162 is fitted at the tail of the bolt 160 between the nut 161 and the movable pressure plate 170. The washer 162 is provided to increase the contact area between the nut and the movable pressure plate, to prevent damage to the movable pressure plate due to pressure concentration when the nut is tightened, and to make the clamping force distribution more uniform.

[0022] The method of using a cable joint drilling tool provided in this embodiment of the utility model is as follows: (1) Align the head of the cable joint 200 with the limiting groove 111 of the base plate 110, so that it is embedded in the groove. The limiting groove 111 restricts the rotation and axial movement of the cable joint head, thus completing the reference positioning of the bottom of the cable joint.

[0023] (2) Place the tail of the cable joint in the clamping space between the fixed jaw block 140 and the movable jaw block 150, ensuring that the part to be drilled faces the drilling equipment or drill bit, and adjust the position of the cable joint so that the tail fits against the fixed jaw block.

[0024] (3) Tighten the nut 161 at the tail of the bolt 160. The nut pushes the movable pressure plate 170 to slide down along the bolt. The first inclined surface 171 of the movable pressure plate contacts and slides relative to the second inclined surface 151 of the movable jaw block, converting the vertical pressure into a horizontal thrust, pushing the movable jaw block 150 to move along the horizontal slide 131 towards the fixed jaw block 140. Until the V-groove 152 of the movable jaw block fits tightly with the tail of the cable joint, and together with the fixed jaw block, clamps the tail of the cable joint, completing the overall fixation.

[0025] (4) After confirming that the cable section is firmly clamped, start the drilling equipment and drill a hole at the preset position of the cable section tail. During the drilling process, the limiting groove 111, together with the movable jaw block 150, the fixed jaw block 140 and other structures, restricts the displacement of the cable section to ensure the accuracy of the hole position.

[0026] (5) After drilling is completed, loosen nut 161, move movable pressure plate 170 upward, and take the cable section out of limit groove 111 to complete the operation.

[0027] The cable joint drilling fixture provided in this embodiment of the utility model has the following beneficial effects: Through the coordinated design of each structure, the utility model achieves precise positioning of the cable joint, avoids the clamping displacement problem of traditional fixtures, improves drilling accuracy, reduces rework, ensures the quality of plug assembly, and is easy to operate, thus improving production efficiency.
