Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and in particular to a positioning blind end structure for machining the outer circle of a belt conveyor roller. Background Technology
[0002] In the manufacturing of belt conveyors, rollers are a core component, and their machining accuracy and stability have a decisive impact on the overall equipment efficiency. In the outer diameter machining process of rollers, a design using end caps with internal hole positioning at both ends is commonly adopted to ensure high precision and stability during the machining process.
[0003] However, traditional blind end designs tend to have a one-piece structure, which lacks flexibility in diameter adjustment. Given the wide range of roller inner bore sizes, covering specifications from φ200 to φ710, multiple specifications of blind ends must be used to meet the machining requirements of different roller inner bore sizes. This significantly increases production costs and inventory management complexity. In practice, whenever the roller inner bore size changes, a corresponding specification of blind end must be replaced to adapt to the machining requirements. This frequent replacement process is time-consuming and labor-intensive, and also restricts production efficiency. Summary of the Invention
[0004] In order to solve the technical problems existing in the above-mentioned technologies, it is necessary to provide a positioning blind head structure for machining the outer circle of belt conveyor rollers.

One end of the guide sleeve is open. The pull rod passes through the guide sleeve along its axial direction. The adjusting support rod is slidably mounted on the guide sleeve along its radial direction. The movable guide block is fixed to the pull rod, and its outer wall slides relative to the inner wall of the guide sleeve. The adjusting component is threaded onto the pull rod and located outside the guide sleeve. Rotating the adjusting component allows the pull rod to move the movable guide block along the guide sleeve, causing the movable guide block to push the adjusting support rod outward along the guide sleeve.
[0006] Preferably, the diameter inside the guide sleeve gradually decreases from the open end to the end opposite to the open end, so that the inside of the guide sleeve forms a conical surface.
[0007] Preferably, the shape of the movable guide block is adapted to the inside of the guide sleeve.
[0008] Preferably, a top head is fixed at the end of the pull rod away from the open end of the guide sleeve.
[0009] Preferably, the movable guide block is fitted onto the pull rod, and a positioning nut threaded onto the pull rod is installed on the side of the movable guide block away from the adjusting member.
[0010] Preferably, a round hole is formed on the guide sleeve for the pull rod to pass through.
[0011] Preferably, a guide hole is formed on the guide sleeve in the radial direction of the guide sleeve for adjusting the sliding of the supporting rod.

[0020] Please refer to Figure 2 、 Figure 3 The utility model provides a kind of positioning plug structure for belt conveyor drum outer circle processing, including guide sleeve 01, pull rod 02, adjusting strut 03, moving guide block 04, adjusting piece 05;One end of guide sleeve 01 is open, pull rod 02 is along the axial direction of guide sleeve 01 and is passed through guide sleeve 01, adjusting strut 03 is slidably installed on guide sleeve 01 along the radial direction of guide sleeve 01, moving guide block 04 is fixed on pull rod 02, and the outer wall of moving guide block 04 and the inner wall of guide sleeve 01 form relative sliding, adjusting piece 05 is screw mounted on pull rod 02, and located at the outside of guide sleeve 01, rotating adjusting piece 05 can make pull rod 02 drive moving guide block 04 and slide along guide sleeve 01, promote moving guide block 04 and push adjusting strut 03 and stretch out outward along guide sleeve 01.When the end of adjusting strut 03 is contacted with the inner hole wall of drum, adjusting strut 03 can be used to form positioning, the positioning installation of plug structure is realized, so that the top center on machine tool clamps drum, realizes drum processing.
[0021] Among them, the diameter inside guide sleeve 01 gradually decreases from open end to the end opposite to open end, so that the conical surface is formed in guide sleeve 01.
[0022] Of course, for moving guide block 04, to ensure that moving guide block 04 moves smoothly in guide sleeve 01, the shape of moving guide block 04 is adapted to the inside of guide sleeve 01, and the shape of moving guide block 04 can also be selected as conical structure.
[0023] In an embodiment, the end of pull rod 02 away from the open end of guide sleeve 01 is fixedly provided with top head 06.Top head 06 can be installed in the end of pull rod 02 in the form of screw connection, so as to be convenient for dismounting and installing.Top head 06 can be convenient for the top center on machine tool to form positioning clamping to pull rod 02
[0024] In an embodiment, moving guide block 04 is sleeved on pull rod 02, and positioning nut 07 is screw connected on pull rod 02 and is installed on the side of moving guide block 04 away from adjusting piece 05.Position of moving guide block 04 is limited by positioning nut 07.Of course, moving guide block 04 can also be installed on pull rod 02 in the form of screw connection, so as to ensure that displacement movement of moving guide block 04 is reduced when moving.
