Description

Technical Field

[0001] This utility model relates to the field of bearing disassembly technology, and in particular to a tooling for removing the inner ring of the bearing from the compaction wheel of a feeding strip machine. Background Technology

[0002] The YJ118 cigarette making machine's VE feeding and forming machine provides qualified tobacco bundles to the SE cigarette making machine. The VE feeding and forming machine uses negative pressure suction to adsorb standard-compliant tobacco onto the suction belt, forming a tobacco bundle. The compaction roller and wing plate in this section form an assembly. The suction belt carries the tobacco bundle towards the cigarette gun, and the tobacco tongue scraper removes the tobacco bundle from the suction belt and compresses it again.

[0003] However, during long-term, high-intensity operation, the 608-2RS bearings on the compaction wheel 100 face severe challenges. A 608-2RS bearing is mounted on each side of the compaction wheel 100. This bearing includes an inner ring 300, an outer ring, rolling elements, and a cage. (See [reference needed]). Figure 1 The inner ring 300 is mounted on the axle 200 of the compaction roller 100, and a circumferential groove 301 is formed on the inner ring 300. Due to continuous high-speed rotation, this bearing is highly susceptible to damage. Once the bearing is damaged, the stability of the tobacco bundle conveying will be severely affected, directly interfering with the quality and efficiency of cigarette production. Therefore, timely replacement of the bearing becomes a necessary measure to ensure the normal operation of the equipment.

[0004] However, in actual bearing replacement operations, numerous thorny problems were encountered. After disassembling the outer ring, rolling elements, and cage of the bearing, it was still difficult to successfully remove the inner ring 300. Firstly, given that the bearing and the compaction wheel 100 are interference-fitted, their connection is extremely tight, and the working space is very narrow. Secondly, the compaction wheel 100 is a brittle alloy; if conventional prying or hammering methods are used to remove the inner ring 300, the slightest carelessness during operation can easily cause irreversible damage to the compaction wheel, rendering it unusable. This would undoubtedly bring unnecessary economic losses and production delays to the company. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a bearing inner ring removal tool for the compaction wheel of a feeder. This invention allows for the rapid removal of the damaged bearing inner ring from the compaction wheel, improving maintenance efficiency while avoiding damage to the compaction wheel body.

[0006] The technical solution to the technical problem solved by this utility model is as follows:

[0007] This application provides a tooling for removing the inner ring of the bearing of the compaction wheel of a feeding strip forming machine, including two clamping blocks arranged opposite each other and an adjusting screw. Each clamping block has an adjusting hole on both sides and a groove on its end face. The opposite side of the clamping block is recessed inward to form an arc groove. The adjusting screw passes through the adjusting hole, thereby connecting the two clamping blocks into one piece. The arc groove fits to form a clamping hole that is adapted to the inner ring with an annular groove, and the groove fits to form a receiving groove that is adapted to the edge of the compaction wheel of the feeding strip forming machine.

[0008] As an improvement to the above solution, the clamping block is made of alloy steel.

[0009] As an improvement to the above solution, the adjusting screw is made of stainless steel.

[0010] As an improvement to the above solution, a second groove is provided on the end face of the clamping block located on the other side of the first groove.

[0011] As an improvement to the above solution, a protruding ring adapted to the annular groove of the inner ring is provided on the inner wall surface of the clamping hole.

[0012] As an improvement to the above solution, the width of the receiving groove is greater than the edge thickness of the compaction wheel to accommodate compaction wheels of different diameters, thereby improving versatility.

[0013] Compared with existing technologies, the above solution has the following advantages or beneficial effects:

[0014] This application provides a bearing inner ring removal tool for the compaction wheel of a feeding strip forming machine. The bearing inner ring is tightly clamped in the clamping hole. The bearing inner ring removal tool can quickly remove the damaged bearing inner ring from the compaction wheel, improving maintenance efficiency while avoiding damage to the compaction wheel body.

[0024] See Figure 1-4This embodiment provides a tooling for removing the inner ring of the bearing of the compaction wheel of a feeding strip forming machine. It includes two opposing clamping blocks 1 and an adjusting screw 2. Each clamping block 1 has adjusting holes 3 on both sides and a groove 4 on its upper surface. The opposite side of each clamping block 1 is recessed inward to form an arc groove 5. The adjusting screw 2 passes through the adjusting holes 3, thereby connecting the two clamping blocks 1 together as a whole. At this time, the two arc grooves 5 cooperate to form clamping holes 6 that fit the inner ring 300, used to clamp the inner ring 300. The two grooves 4 cooperate to form receiving grooves 7, used to accommodate the edge of the compaction wheel 100.

[0025] A protruding ring 61, adapted to the annular groove 301 of the inner ring 300, is provided outwardly on the inner wall surface of the clamping hole 6. When the bearing inner ring 300 is removed, the protruding ring 61 can be embedded into the annular groove 301 of the inner ring 300, significantly enhancing the mechanical engagement between the two. This tight and stable fit greatly improves the clamping force and stability of the clamping hole 6 on the inner ring 300, thereby improving the removal efficiency of the inner ring 300.

[0026] In actual operation, the distance between the two clamping blocks 1 can be flexibly adjusted by rotating the adjusting screw 2. (See reference...) Figure 5 and 6 When the appropriate spacing is adjusted, the inner ring 300 on one side of the compaction wheel 100 is tightly clamped in the clamping hole 6, and the edge of the compaction wheel 100 is securely housed in the receiving groove 7. Then, the inner ring 300 is removed at the same time as the bearing inner ring is removed from the tooling. Repeat the above operation to remove the inner ring 300 on the other side of the compaction wheel 100.

[0027] in,

[0028] Each clamping block 1 is made of high-strength alloy steel, which has excellent wear resistance and compressive strength, ensuring that the tooling is not easily deformed or damaged during frequent use, effectively extending the service life of the tooling. A second groove 8 is provided on the end face (lower end face) of the clamping block 1 on the other side of the first groove 4, thereby reducing the overall weight of the clamping block 1. While ensuring the strength of the clamping block 1, the lighter weight makes it easier for operators to handle, install, and adjust it during actual operation.

[0029] The adjusting screw 2 is made of high-quality, high-strength stainless steel, which not only has good rust resistance but can also withstand large tensile forces.

[0030] In the prior art, the compactor roller 100 typically comes in three sizes, with these three sizes exhibiting a regular increasing characteristic in size, their diameters increasing sequentially by 0.2 mm. The width of the receiving groove 7 is sufficient to accommodate the edges of these three sizes of compactor rollers 100, ensuring that any size of compactor roller 100 can be placed within the receiving groove 7. In other words, the width of the receiving groove 7 is greater than the edge thickness of the compactor roller 100 to accommodate compactor rollers 100 of different diameters, thereby improving the versatility of the bearing inner ring removal tooling.

[0031] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
