Description

Technical Field

[0001] The utility model relates to a core-adjusting and mounting device for milling the outer circle of a supporting shaft roller sleeve, and belongs to the technical field of mechanical processing. Background Art

[0002] The support shaft roller sleeve is a similar series of parts. It is a tube-shaped structure with various sizes and specifications, and there are differences in thin wall thickness, axial size, and diameter. The support shaft roller sleeve needs to be milled and ground on the outer circle, and the coaxiality of its inner and outer circles is required to be high. Therefore, tooling is required to meet its mounting accuracy during the milling operation.

[0003] At present, tooling fixtures generally take three forms:

[0004] The first is to use expansion clamping for the inner wall of the tube. This clamping meets the coaxial stability requirements of the inner circle, but its axial and radial dimensions are small in range and its versatility is poor. In addition, when milling the outer circle, there is no internal support at both ends, and deformation accuracy deviation is prone to occur during milling.

[0005] The second method is to use a clamp for the outer wall of the tube. The clamp cannot achieve one-time external cylindrical milling, and it is prone to deformation accuracy deviation.

[0006] The third method is to clamp and fix the two ends of the roller sleeve, that is, to use clamping plates at both ends, and the clamping plates use the end faces as reference points, which can easily affect the coaxiality, and at the same time, the outer edge side that abuts against the clamping plates cannot be milled. Utility Model Content

[0007] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art, and to propose a core-adjusting mounting device for supporting the outer circle milling of a shaft roller sleeve in view of the many problems existing in traditional expansion clamping, clamping and clamping at both ends.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] The centering and mounting device for the outer cylindrical milling of the support shaft roller sleeve comprises a core shaft for passing through the support shaft roller sleeve, and two clamping flanges which are arranged at intervals and are sleeved on the core shaft. The two ends of the core shaft are respectively provided with threaded sections, and the free ends of the threaded sections are respectively provided with rotating matching ends. An assembly locking nut is provided on any of the threaded sections. The two clamping flanges respectively have mating end faces which are mating with each other, and the mating end faces include relative end faces and conical walls which are arranged on the outer periphery of the relative end faces.

[0010] Preferably, a radially extending opening groove is provided on the core shaft channel of any one of the clamping flanges.

[0011] Preferably, any of the clamping flanges is provided with an axial through hole for coupling with the hanging ear;

[0012] One end of the axial matching through hole passes through the opposite end surface.

[0013] Preferably, a gasket sleeved on the core shaft is provided between any of the clamping flanges and the corresponding assembly locking nut.

[0014] Preferably, at least one cut surface groove is provided on the rotational coupling end.

[0015] Preferably, a centering groove is provided on the end surface of the rotational coupling end.

[0016] Preferably, the angle between the conical wall and the axis of the core shaft is α, 15°≤α≤75°.

[0017] Preferably, the angle α=30°.

[0018] Preferably, the angle α=45°.

[0019] The beneficial effects of the utility model are mainly reflected in:

[0020] 1. Meet the compatible mounting requirements of various specifications of support shaft roller sleeves.

[0021] 2. Stable locking and clamping can be achieved through the relative cooperation of the conical wall, and the existence of the gap can realize the entire milling and grinding of the outer wall without any processing dead angle.

[0022] 3. The open groove design enables flexible assembly and disassembly of the clamping flange, making the loading and unloading operations of the support shaft roller sleeve smoother and more efficient.

[0023] 4. The overall design is simple and ingenious, the manufacturing cost is effectively controlled, and it is suitable for promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] The utility model provides a core adjustment and mounting device for supporting the outer circle milling of a shaft roller sleeve, such as Figures 1 to 4 As shown, it includes a core shaft 1 for passing through the support shaft roller sleeve 100, two clamping flanges 2 sleeved on the core shaft 1 and arranged at intervals, threaded sections 3 are respectively provided at both ends of the core shaft 1, and a rotating matching end 4 is provided at the free end of the threaded section 3, and an assembly locking nut 5 is provided on any threaded section 3, and the two clamping flanges are respectively provided with mating end faces 6 that are mating with each other, and the mating end faces include a relative end face 61 and a conical wall 62 arranged on the outer periphery of the relative end face.

[0032] Specific implementation process and principle description:

[0033] When clamping the support shaft roller sleeve 100, first pass the core shaft 1 through the support shaft roller sleeve 100 so that its two ends are exposed, and after the clamping flanges 2 are sleeved on the two exposed ends, the corresponding assembly locking nuts 5 are screwed and locked. As they are locked, the relative end faces 61 of the two clamping flanges 2 penetrate into the inner cavity of the support shaft roller sleeve 100, and the conical wall 62 abuts against the inner ring of the end face of the support shaft roller sleeve 100, thereby achieving the clamping of the support shaft roller sleeve 100. After clamping, the rotating mating ends 4 on both sides can be mounted by matching with the rotating drive source and the follow-up rotating part.

[0034] It should be noted that the core shaft is used for penetrating mounting design and the two conical walls 62 are matched to meet the compatible mounting of the support shaft roller sleeve 100 with various axial specifications and diameter specifications.

[0035] In addition, there is a gap 10 between the tapered wall 62 and the outer wall end surface of the support shaft roller sleeve 100, so the entire outer peripheral wall can be milled without any dead angle.

[0036] In a specific embodiment, Figure 1 and Figure 4 As shown, a radially extending opening groove 7 is provided on the core shaft channel of any clamping flange 2.

[0037] Specifically, in general, in order to carry out the assembly and disassembly of the support shaft roller sleeve 100, one of the clamping flanges 2 needs to be disassembled from the core shaft. Therefore, during operation, an assembly locking nut 5 needs to be completely separated from the core shaft to realize the assembly and disassembly of the support shaft roller sleeve 100.

[0038] By designing the opening groove 7, the clamping flange 2 can be easily assembled and disassembled without completely separating it from the core shaft, thereby meeting the assembly and disassembly requirements of the support shaft roller sleeve 100.

[0039] In a specific embodiment, any clamping flange is provided with an axial mating through hole 8 for mating with a hanging ear 80 ; one end of the axial mating through hole passes through the opposite end surface 61 .

[0040] In this way, the mounting requirements of the mounting ear 80 are met, and the hoisting connection and coordination are convenient, and the assembly and disassembly operations are easy.

[0041] In a specific embodiment, a gasket 9 sleeved on the core shaft is provided between any clamping flange and the corresponding assembly locking nut.

[0042] The gasket ring 9 can meet the requirements of intermediate extension support, making the adaptation range of the axial size wider. At the same time, the gasket ring 9 can make the locking after screwing more reliable and stable, and it is not easy to loosen during the processing.

[0043] In a specific embodiment, at least one facet groove 41 is provided on the rotational coupling end 4. A centering groove 42 is provided on the end surface of the rotational coupling end.

[0044] In this way, the matching requirements between the rotational matching end 4 and the rotational driving source or the follower rotating part are met.

[0045] In a specific embodiment, the angle between the conical wall 62 and the axis of the core shaft is α, 15°≤α≤75°.

[0046] When the angle requirements within this range are met, the annular surface fit and abutment are relatively reliable and stable.

[0047] In a preferred embodiment, the angle α=30°. This embodiment is mainly used for generally regular support shaft roller sleeves 100 to meet the requirements of reliable and stable abutment force and better compatibility.

[0048] In a preferred embodiment, the angle α=45°. This embodiment is mainly used to support the structure with a ring platform in the shaft roller sleeve 100. On the one hand, it can effectively avoid the ring platform, and on the other hand, it can also improve the reliability and stability of the ring surface abutment locking.

[0049] From the above description, it can be found that the core adjustment and mounting device for the outer cylindrical milling of the support shaft roller sleeve of the utility model meets the compatible mounting requirements of various specifications of support shaft roller sleeves. The relative matching of the conical wall can achieve stable locking and clamping, and the existence of the gap can realize the full milling and forming of the outer peripheral wall, and there is no processing dead angle. The open groove design can realize the flexible assembly and disassembly of the clamping flange, making the loading and unloading operations of the support shaft roller sleeve smoother and more efficient. The overall design is simple and ingenious, the manufacturing cost is effectively controlled, and it is suitable for promotion and application.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
