Description

Technical Field

[0001] The utility model relates to the technical field of cone sleeve disassembly, in particular to a grinding roller cone sleeve quick disassembly device. Background Art

[0002] The taper sleeve is assembled between the outer circle of the tapered surface of the roller shaft and the inner circle of the roller ring, and an interference fit is achieved by applying pressure. The taper sleeve plays a connecting role in the roller ring assembly. When it is inspected and repaired, the taper sleeve often needs to be removed. Due to the firm interference fit during assembly, disassembly is very inconvenient. If disassembly is forced, it is easy to cause the earrings of the taper sleeve to break or fatigue cracks to occur, which brings a lot of inconvenience to subsequent maintenance and production. In addition, the common disassembly device is relatively bulky, and the operation and maintenance itself are also relatively cumbersome, and the cost is also high. If a structure that can be quickly disassembled without affecting its normal use is set, this structure uses a motor to drive the threaded rod to rotate to generate thrust to take out the taper sleeve. The overall structure is simple and easy to operate. It is suitable for disassembly of taper sleeves of different specifications, which improves practicality. Therefore, a grinding roller taper sleeve quick disassembly device is proposed. Utility Model Content

A motor 5 is arranged on the upper surface of the U-shaped block 6, and the output shaft of the motor 5 is fixedly connected to a limiting block 14, wherein the limiting block 14 is movably clamped with the limiting block 2 13, and two threaded rods 2 7 are threadedly sleeved on the inner surfaces of the two limiting strips 2. This adjustment structure is convenient for adjustment through threaded connection.

[0024] The left and right ends of the two limit bars 2 are movably sleeved with gaskets 12, wherein the left and right ends of the two limit bars 2 are threadedly sleeved with nuts 9, and the upper surface of the clamping plate 14 is penetrated with threaded holes 15, wherein the threaded holes 15 are threadedly sleeved with threaded rods 3. At this time, the threaded rods 3 fixedly connected to the limit blocks 13 are threadedly sleeved downward, and the gaskets 16 will contact the end surface of the cone sleeve during the descent process. The motor 5 rotates to drive the threaded rods 3 to exert force downward.

[0026] Working principle:

[0027] The cone sleeve is assembled between the outer circle of the cone surface of the roller shaft and the inner circle of the roller ring 1, and an interference fit is achieved by applying pressure. Due to the firm interference fit during assembly, disassembly is very inconvenient. This situation can be avoided by the following structure: the cone sleeve is placed above the limit bar 2, and the upper surfaces of the two clamping blocks 11 are threadedly sleeved with limit rods 18, and a clamping plate 14 is clamped above the two limit rods 18. A rotating mechanism composed of a U-shaped block 6, a motor 5 and a limit block 1 4 is arranged above the clamping plate 14. The limit block 1 4 is clamped with the limit block 2 13. The motor 5 is started to rotate and drives the limit block 2 13 clamped therewith to rotate together. At this time, the threaded rod 1 3 fixedly connected to the limit block 2 13 is screwed downward. During the descent, the cushion block 16 will contact with the end face of the tapered sleeve, and the motor 5 will rotate to drive the threaded rod 3 to exert force downward. At this time, the adjusting structure is forced to drive the roller ring 1 to rise, so that it is disengaged from the clamping connection with the tapered sleeve, and it is taken out to achieve quick disassembly to improve the production and maintenance efficiency. There are two limit bars 2 threadedly connected between the two limit bars 2 through a nut 9, and two threaded rods 7 are internally threadedly connected between the two limit bars 2. This adjusting structure is easy to adjust through threaded connection. When the tapered sleeve needs to be disassembled, the adjusting mechanism is adjusted to be threadedly fixed together with the roller ring 1. The overall structure is simple and easy to operate. It is suitable for disassembly of roller rings 1 of different specifications, which improves practicality.
