[0002] In the field of parts processing technology, heavy shaft parts need to be supported and centered during processing. For example, a Chinese patent with patent publication number CN218983920U discloses a non-destructive support device for shaft parts used in horizontal lathes. The structure of rotating the inner sleeve equipped with multiple preloaded parts and the mounting seat on the base can reduce the friction between the parts and the support structure and improve the reliability of the support structure. However, its overall structure is relatively complex, the cost is high, and it has no telescopic function, and its functional expansion needs to be further optimized.

[0029] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0030] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a shaft part supporting device and part processing equipment provided by the utility model.

[0031] A shaft parts supporting device, comprising:

[0032] A mounting frame 2, on which a limiting hole for shaft parts to pass through is opened;

[0033] The telescopic mechanism 1 is arranged in a circular array beside the limiting hole. The telescopic mechanism 1 includes a flange seat 6, a telescopic sleeve 5, a rolling element 4 and a telescopic adjustment component:

[0034] The flange seat 6 is installed on the mounting frame 2, and the telescopic sleeve 5 is slidably arranged in the flange seat 6 in the radial direction of the limiting hole. A rolling element 4 is arranged at the first end of the telescopic sleeve 5. The telescopic sleeve 5 is used to drive the rolling element 4 to move along the radial direction of the limiting hole. The rolling element 4 is used to abut against and support shaft parts; the second end of the telescopic sleeve 5 is connected to the telescopic adjustment component, and the telescopic adjustment component is telescopically arranged in the flange seat 6 and is used to drive the telescopic sleeve 5 to telescopically move relative to the flange seat 6, thereby adjusting the distance between the rolling element 4 and the center of the limiting hole.

[0035] Here, the “flange seat 6” means the main structure of the telescopic mechanism 1 installed on the mounting frame 2. In some embodiments, the flange seat 6 is a hollow cylindrical or frame structure to provide installation space for the telescopic sleeve 5 and the telescopic adjustment assembly.

[0036] Here, the meaning of "telescopic sleeve 5" refers to a telescopic part slidably disposed in the flange seat 6. In some embodiments, the telescopic sleeve 5 is a hollow cylindrical sleeve structure, and may also be a frame structure.

[0037] The utility model installs the telescopic mechanism 1 through the mounting frame 2, and the telescopic sleeve 5 of the telescopic mechanism 1 drives the rolling element 4 to move, and the rolling element 4 provides a fulcrum to limit the support of the shaft parts, which has better expansibility and can adapt to the support, limit and orientation functions of parts of a wider size. The telescopic adjustment component can drive the telescopic sleeve 5 to telescope, and the position of the telescopic sleeve 5 and the rolling element 4 can be adjusted to facilitate the installation and disassembly of the workpiece. The telescopic mechanism 1 is arranged in a circular array next to the limit hole of the mounting frame 2, that is, multiple rolling elements 4 are used to support the shaft parts in multiple directions, which can effectively improve the support rigidity of the parts.

[0038] It should be noted that the telescopic mechanism 1 is preferably arranged in four annular arrays beside the limiting holes to achieve the four-point orientation function, so that the loading and unloading of the workpiece will not be too cumbersome and the rigidity of the support can be effectively improved.

[0039] Preferably, please refer to Figure 2 As shown, the telescopic adjustment assembly includes a telescopic screw 8, which cooperates with a preset mounting hole on the end face of the flange seat 6, and the first end of the telescopic screw 8 is threadedly connected to the telescopic sleeve 5; the second end of the telescopic screw 8 extends out of the outside of the flange seat 6 and is provided with a driving part, and the driving part is used to drive the telescopic screw 8 to rotate to drive the telescopic sleeve 5 to perform linear motion; one of the telescopic sleeve 5 and the flange seat 6 is provided with a guide groove arranged along the linear motion direction of the telescopic sleeve 5, and the other is provided with a guide part embedded in the guide groove and used to guide the sliding along the guide groove.

[0040] It can be understood that one end of the telescopic screw 8 is connected to the end surface of the flange seat 6 and the other end is threadedly connected to the telescopic sleeve 5, similar to the principle of the screw nut transmission mechanism. By rotating the telescopic screw 8, the telescopic sleeve 5 can be driven to perform linear motion.

[0041] It should be noted that the guide groove provided on the telescopic sleeve 5 is a strip groove structure, and the guide groove is used to cooperate with the guide portion protruding on the flange seat 6 to guide the linear motion of the telescopic sleeve 5. The guide portion can be protruding on the inner wall of the flange seat 6. Of course, the utility model does not exclude the scheme that the telescopic screw 8 and the flange seat 6 are threadedly matched, and the telescopic screw 8 and the telescopic sleeve 5 are connected by a bearing. In this case, the position of the telescopic screw 8 can be adjusted by rotating the telescopic screw 8, thereby driving the telescopic sleeve 5 to move, and the position adjustment function of the telescopic sleeve 5 can also be realized.

[0042] Preferably, please refer to Figure 2As shown, the telescopic adjustment assembly also includes a locking rod 7 and a limit piece 12, the locking rod 7 is slidably inserted into the preset central axis hole of the telescopic screw 8, the first end of the locking rod 7 is provided with a locking platform, the second end of the telescopic sleeve 5 is provided with a limit boss, the locking platform is used to abut the limit boss to limit the maximum stroke of the telescopic sleeve 5 relative to the flange seat 6, the second end of the locking rod 7 extends out of the outer end of the telescopic screw 8, the limit piece 12 is sleeved on the second end of the locking rod 7, the limit piece 12 is threadedly connected to the locking rod 7, the limit piece 12 is used to drive the locking rod 7 to move axially to adjust the axial limit position of the locking platform; the inner wall of the second end of the telescopic sleeve 5 is convexly provided with a positioning platform, the central through hole of the positioning platform is a screw hole structure, and the central through hole of the positioning platform is threadedly connected to the telescopic screw 8, the diameter of the locking platform of the locking rod 7 is larger than the diameter of the central through hole, and the locking platform is used to abut the positioning platform to strengthen the limiting telescopic sleeve 5.

[0043] It is understandable that the position of the locking rod 7 can be limited by the cooperation of the limiting member 12 and the locking platform, thereby strengthening the position limitation of the telescopic sleeve 5, improving the anti-vibration ability of the telescopic sleeve 5, and ensuring the stability of the support device for the parts. The limiting member 12 can be a nut. Rotating the limiting member 12 can adjust the length of the locking rod 7 extending out of the outer end of the flange seat 6, that is, adjust the length of the locking rod 7 in the flange seat 6. After the telescopic sleeve 5 is adjusted to the right position with the telescopic screw 8, the telescopic sleeve 5 is limited by the locking platform. The locking rod 7 and the limiting member 12 (see Figure 3 ) is responsible for locking, which ensures that after the rolling element 4 is adjusted to the appropriate position, it will not be displaced due to vibration during processing.

[0044] In addition, the interior of the telescopic sleeve 5 is a hollow structure, and the locking platform is protruded inside the telescopic sleeve 5. The locking platform and the telescopic sleeve 5 are preferably an integrally formed structure. The setting of the locking platform structure can enhance the strength of the connection between the telescopic sleeve 5 and the telescopic screw 8, and at the same time can cooperate with the locking rod 7 to limit the telescopic sleeve 5.

[0045] Preferably, please refer to Figure 2 As shown, the telescopic adjustment assembly also includes an end cover 9, a pressure cover 11 and a clamping bolt 10. The end cover 9 is fixedly connected to the end face of the flange seat 6 by bolts. A mounting hole is opened on the end cover 9 for the telescopic screw 8 to pass through. A limiting platform is arranged on the telescopic screw 8. The diameter of the limiting platform is larger than the diameter of the mounting hole on the end cover 9. The limiting platform is used to abut against the end cover 9 to clamp the telescopic screw 8. The pressure cover 11 is connected to the outer end of the end cover 9 by the clamping bolt 10, and the pressure cover 11 is used to lock the limiting platform to a limit position.

[0046] It is understandable that the telescopic screw 8 is installed and limited by the end cover 9 and the pressure cover 11, which can facilitate the disassembly, maintenance and replacement of the telescopic screw 8. It should be noted that lubricating oil can be applied between the telescopic screw 8 and the end cover 9 and the pressure cover 11 to reduce the wear of the telescopic screw 8 when it rotates.

[0047] It should be noted that the combination of the end cover 9 and the pressure cover 11 ensures that the telescopic screw 8 can only rotate but cannot move axially. Optionally, a pad is slidably arranged in the telescopic sleeve 5, and the pad is provided with a through hole for the locking rod 7 to pass through, and the first end of the pad is used to abut against the positioning platform, and the second end of the pad is used to abut against the limit locking platform.

[0048] It is understandable that the pad can play a buffering and protective role, reducing the greater impact force caused by the locking platform directly contacting the positioning platform and causing more wear. The pad can also increase the contact area with the locking platform, reduce the stress concentration of the locking platform, increase the service life of the stress-bearing part, and enhance the stability of the limit.

[0049] Optionally, a notch is provided at the top of the limiting hole on the mounting frame 2, and the telescopic mechanism 1 is divided into four and arranged beside the limiting hole, and two of the telescopic mechanisms 1 are located on both sides of the notch of the limiting hole.

[0050] It is understandable that a notch is provided on the limiting hole, which facilitates the direct placement of parts into the limiting hole, and the stable centering of the parts can be achieved through four telescopic mechanisms 1. Two of the telescopic mechanisms 1 are located on both sides of the notch, that is, above the center line of the limiting hole, so that the telescopic mechanisms 1 are evenly distributed at four points, ensuring the stability of the clamping and centering of shaft parts.

[0051] Preferably, please refer to Figure 1 and Figure 2 As shown, the rolling element 4 is a bearing or a roller, a core shaft 3 is disposed at the first end of the telescopic sleeve 5 , and the rolling element 4 is disposed on the core shaft 3 .

[0052] Specifically, the axis of the rolling element 4 is arranged parallel to the axis of the upper limit hole on the mounting frame 2 .

[0053] It can be understood that the rolling member 4 is driven to adjust its position through the telescopic sleeve 5, and the rolling member 4 is arranged parallel to the plane of the mounting frame 2. When the rolling member 4 contacts the surface of the part, since the rolling member 4 and the part are in rolling contact, the rolling member 4 of each telescopic mechanism 1 can be conveniently adjusted to the position, and the damage to the surface of the part can be minimized as much as possible. The wear of the rolling member 4 serving as a fulcrum can also be reduced, which can improve the convenience of adjustment and the stability of support, and at the same time help to extend the service life of the parts.

[0054] Preferably, please refer to Figure 1 and Figure 3As shown, scale lines are provided on the outer wall of the telescopic sleeve 5 for observing the distance that the telescopic sleeve 5 extends out from the outer end of the flange seat 6 .

[0055] It is understandable that the scale lines can facilitate and intuitively observe the position of the telescopic sleeve 5 so as to accurately adjust the position of each rolling element 4 and achieve more precise support and centering functions.

[0056] According to another aspect of the utility model, a parts processing equipment is also provided, which includes the above-mentioned shaft parts supporting device.

[0057] The parts processing equipment of the utility model also has the above-mentioned beneficial effects.

[0058] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0059] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
