Description

Technical Field

[0001] This utility model relates to the field of tapered pin disassembly technology, and more specifically, to a tapered pin disassembly tool. Background Technology

[0002] In the field of mechanical assembly and maintenance, tapered pins are widely used as positioning and connecting parts in various types of mechanical equipment. They achieve a tight fit through their tapered shape, ensuring connection stability and providing reliable assurance for precise equipment installation. However, disassembling tapered pins can be quite challenging when maintenance, repair, or component replacement is required.

[0003] Currently, the disassembly of tapered pins typically involves two symmetrical grippers. During disassembly, both the grippers and the locating pin must be held steady before rotating the threaded rod. However, because the threaded rod is not in contact with the shaft, the grippers may become misaligned or shifted, affecting the disassembly of the tapered pin. Therefore, improvements and optimizations are needed. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a tapered pin disassembly tool, which has the advantage of improved stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tapered pin disassembly tool, including a threaded sleeve.

[0006] The threaded sleeve has a threaded rod threaded inside, with the top and bottom of the threaded rod penetrating the upper and lower sides of the threaded sleeve. A crossbar is fixedly installed above the threaded rod. A limit arm is fixedly installed on the outer side of the threaded sleeve. One end of the limit arm is rotatably connected to one end of a connecting rod, and the other end of the connecting rod is rotatably fitted with a gripper. A fixing plate is fixedly fitted onto the outer surface of the threaded sleeve, and a spring is fixedly installed at the bottom of the fixing plate.

The limit block is movably connected to a second friction surface, and a disassembly part is fixedly installed at the bottom of the gripper.

[0007] As a preferred embodiment of this utility model, the gripper is composed of a first arc-shaped portion and a second arc-shaped portion, with the first arc-shaped portion located above the second arc-shaped portion.

[0009] As a preferred embodiment of this utility model, two limiting rods are movably installed above the fixed plate. The two limiting rods are evenly arranged above the fixed plate. A positioning plate is fixedly installed on the top of the limiting rod. The bottom of the limiting rod passes through the upper and lower sides of the fixed plate and is fixedly connected to the limiting block.

[0010] As a preferred embodiment of this utility model, the side of the disassembly part has two mounting holes, the outer surface of the disassembly part is movably fitted with a contact plate, a locking bolt is rotatably installed on the outer side of the contact plate, one end of the locking bolt extends into the disassembly part and the mounting hole, the locking bolt is threaded into the mounting hole, and the contact plate and the disassembly part are fixed by the locking bolt.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, this utility model provides a tapered pin disassembly tool, including a threaded sleeve 1.

[0020] The threaded sleeve 1 has a threaded rod 4 threaded inside. The top and bottom of the threaded rod 4 pass through the upper and lower sides of the threaded sleeve 1. A crossbar 401 is fixedly installed above the threaded rod 4. A limit arm 101 is fixedly installed on the outer side of the threaded sleeve 1. One end of the limit arm 101 is rotatably connected to one end of a connecting rod 102. The other end of the connecting rod 102 is rotatably mounted with a gripper 103. A fixing plate 2 is fixedly fitted onto the outer surface of the threaded sleeve 1. A spring 202 is fixedly installed at the bottom of the fixing plate 2. A limit block 201 is movably fitted onto the outer surface of the threaded sleeve 1. The bottom of the spring 202 is fixedly connected to the top of the limit block 201. The limit block 201 is movably connected to the second friction surface 203. A disassembly part 106 is fixedly installed at the bottom of the gripper 103.

[0021] When the worker needs to disassemble the tapered pin, first move the limiting block 201 upward, and the spring 202 will be compressed. Then, clamp the four disassembly parts 106 on the notch of the tapered pin. After releasing the limiting block 201, the spring 202 will push the limiting block 201 downward, and the limiting block 201 will contact the gripper 103, fixing the position of the gripper 103. The worker holds the device and then rotates the crossbar 401. When the crossbar 401 rotates, it will drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, since the threaded sleeve 1 and the threaded rod 4 are threadedly connected, the threaded rod 4 will move downward as it rotates. When the bottom of the threaded rod 4 contacts the shaft of the tapered pin, continue to rotate the threaded rod 4, and then the tapered pin can be disassembled.

[0022] By moving the limiting block 201 upwards, and then clamping the four disassembly parts 106 onto the notch of the tapered pin, and then releasing the limiting block 201 and rotating the crossbar 401 to drive the rotation of the threaded rod 4, the tapered pin can be disassembled. Compared with the traditional device, this device, through the cooperation of the limiting block 201 and the contact plate 3, can firmly fix the device onto the notch of the tapered pin, and can make the threaded rod 4 contact the shaft, thereby improving stability and disassembly efficiency.

[0023] The gripper 103 is composed of a first arc-shaped portion 104 and a second arc-shaped portion 105, with the first arc-shaped portion 104 located above the second arc-shaped portion 105.

[0024] The three openings of the first arc-shaped portion 104 and the second arc-shaped portion 105 facilitate the limiting block 201 to limit the gripper 103 and facilitate the disassembly of the tapered pin.

[0025] The first arc-shaped part 104 has a first friction surface 108 on one side of its top end, and the limiting block 201 has a second friction surface 203 on its side. The second friction surface 203 is movably connected to the first friction surface 108.

[0026] By designing the first friction surface 108 and the second friction surface 203, the friction between the limiting block 201 and the gripper 103 can be increased, thereby improving the stability of the gripper 103 in the limiting position.

[0027] Two limiting rods 204 are movably installed on the top of the fixed plate 2. The two limiting rods 204 are evenly arranged on the top of the fixed plate 2. A positioning plate 205 is fixedly installed on the top of the limiting rods 204. The bottom of the limiting rods 204 passes through the upper and lower sides of the fixed plate 2 and is fixedly connected to the limiting block 201.

[0028] The disassembly part 106 has two mounting holes 107 on its side. A contact plate 3 is movably sleeved on the outer surface of the disassembly part 106. A locking bolt 301 is rotatably installed on the outer side of the contact plate 3. One end of the locking bolt 301 extends into the interior of the disassembly part 106 and the mounting hole 107. The locking bolt 301 is threaded into the mounting hole 107. The contact plate 3 and the disassembly part 106 are fixed by the locking bolt 301.

[0029] The design of the locking bolt 301 allows the contact plate 3 to be disassembled, thus facilitating the installation of different types of contact plates 3 and enabling disassembly for different types of tapered pins.

[0030] The number of limiting arms 101, connecting rods 102 and grippers 103 are four, and each group consists of one limiting arm 101, one connecting rod 102 and one gripper 103, which are evenly arranged on the outer surface of the threaded sleeve 1.

[0031] The design of four limiting arms 101, connecting rods 102 and grippers 103 can improve the stability during disassembly.

[0032] Working principle and usage process of this utility model:

[0033] When the worker needs to disassemble the tapered pin, first move the limiting block 201 upward, and the spring 202 will be compressed. Then, clamp the four disassembly parts 106 on the notch of the tapered pin. After releasing the limiting block 201, the spring 202 will push the limiting block 201 downward, and the limiting block 201 will contact the gripper 103, fixing the position of the gripper 103. The worker holds the device and then rotates the crossbar 401. When the crossbar 401 rotates, it will drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, since the threaded sleeve 1 and the threaded rod 4 are threadedly connected, the threaded rod 4 will move downward as it rotates. When the bottom of the threaded rod 4 contacts the shaft of the tapered pin, continue to rotate the threaded rod 4, and then the tapered pin can be disassembled.
