[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figures 1 to 2 As shown, the utility model provides a bearing and bearing seat separation platform for a Roots vacuum pump, including a base 1, a placement groove 2 for placing the bearing seat is opened on the base 1, an ejector 3 adapted to the diameter of the bearing is provided in the placement groove 2, and a pressing member 4 is symmetrically provided on the base 1 and located outside the placement groove 2. The bearing and the bearing seat are located between the ejector 3 and the pressing member 4. The ejector 3 and the pressing member 4 move vertically and respectively abut against the bearing and the bearing seat, and eject the bearing in the bearing seat as the ejector 3 moves vertically.
[0023] Among them, regarding the structural design between the placement groove 2, the ejector 3 and the pressing member 4:
[0024] The symmetrical design of the pressing member 4 ensures that the bearing and the bearing seat maintain the correct position during the disassembly process, preventing the bearing from shifting or tilting. Furthermore, the gentle action of the ejector 3 and the pressing member 4 can reduce damage to the bearing and the bearing seat, and conveniently eject or press the bearing from the bearing seat. The overall solution simplifies the maintenance process. In situations where frequent bearing replacement is required, this design can significantly improve maintenance efficiency, reduce equipment downtime, and improve production efficiency.
[0025] On the basis of the above scheme, further preferred schemes include:
[0026] The ejector 3 includes a transmission member 31 and an ejector pad 32 . The transmission member 31 is disposed in the base 1 . An output end of the transmission member 31 is connected to the ejector pad 32 for driving the ejector pad 32 to move vertically.
[0027] The transmission member 31 may be a linear driving transmission device such as a hydraulic jack, a hydraulic cylinder, a pneumatic cylinder or an electric push rod;
[0028] By driving the ejection pad 32 through the transmission member 31, the moving distance and speed of the ejection pad 32 can be precisely controlled, so that it can be adjusted according to different working environments and requirements to adapt to different force requirements and speed requirements, making the movement of the ejection pad 32 smoother, reducing the instability and damage to the bearings that may be caused by manual operation, and also reducing the risk of direct manual operation, thereby improving the safety of operation.
[0029] Preferably, the placement groove 2 includes a stepped circular groove 21 and a through hole 22. The stepped circular groove 21 is opened on the base 1, and the through hole 22 is opened in the middle of the stepped circular groove 21. The diameters of the through hole 22 and the stepped circular groove 21 increase successively along the vertical direction.
[0030] There are multiple ejection pads 32 with different diameters. When the diameter of the ejection pad 3 matches a certain step of the stepped circular groove 21 , the height of the ejection pad 3 is smaller than the height of the step of the stepped circular groove 21 .
[0031] The bearing seat is placed on a stepped circular groove of the stepped circular groove 21, and the ejector pad 32 corresponding to the bearing is located below the bearing seat and is placed on a stepped circular groove that matches the diameter of the bearing. The ejector 3 is located at the through hole 22.
[0032] More specifically, when the bearing seat is located on the lowest step groove of the stepped circular groove 21 or the bearing is not located on the stepped circular groove, the ejection pad 3 is located inside the ejection pad 3 and is driven upward by the transmission member 31 to eject the bearing.
[0033] Therefore, for bearings of different sizes, multiple ejection pads 32 with different diameters can be adapted to the different steps of the stepped circular groove 21, which increases the versatility and flexibility of the device. By controlling the height of the ejection pad 32 to be smaller than the height of the corresponding step of the stepped circular groove 21, the bearing seat can be prevented from shifting on the base 1, ensuring the correct position of the bearing seat and ensuring that the bearing seat can always be firmly placed on the base 1, preventing the bearing seat from being unstable due to excessive lifting of the bearing.
[0034] Preferably, the base 1 includes a top platform 11 and a plurality of pillars 12 . The plurality of pillars 12 are fixedly connected to ends of the top platform 11 , and a bottom platform 13 is provided between the plurality of pillars 12 .
[0035] Multiple pillars 12 are fixedly connected to the ends of the top platform 11, and a bottom platform 13 is provided therebetween. The structural design ensures its ability to withstand large weight or dynamic loads while also reducing the overall weight for easier movement. It also provides an installation plane for other components of the equipment, has a wide field of view, and makes the installation, adjustment and maintenance of components more convenient.
[0036] Preferably, the pressing member 4 includes a vertical rod 41 symmetrically arranged on the base 1 and located outside the placement groove 2, and the outside of the vertical rod 41 is vertically slidably connected with a pressing block 42 and a locking nut 43 threadedly connected.
[0037] The clamping block 42 is slidably connected to the outside of the vertical rod 41, and mainly adapts to the height of the bearing seat by adjusting the position of the clamping block 42. The clamping block 42 can rotate freely in the vertical rod 41 to meet the needs of bearing seats of different sizes. The clamping block 42 can be rotated to avoid affecting the taking and placing operation of the bearing seat, and the clamping force is applied to the clamping block 42 through the threaded connection of the locking nut 43, so that the bearing seat is stably placed on the base 1, which can ensure the stability of the clamping part during operation.
[0038] In addition to the above-described manually operated pressing member 4 solution, another structural solution for automatically operating the pressing member 4 is also provided, the specific solution of which is not shown in the drawings.
[0039] like Figure 3 As shown, the details are as follows:
[0040] The pressing member 4 includes a telescopic member 5 symmetrically arranged on the base 1 and located outside the placement groove 2. The output end of the telescopic member 5 is provided with a pressing block 6 for driving the pressing block 6 to move vertically.
[0041] The telescopic member 5 can be a linear driving transmission device such as a hydraulic jack, a hydraulic cylinder, a pneumatic cylinder or an electric push rod;
[0042] The introduction of the telescopic part 5 allows the clamping process to be controlled mechanically, reducing the risk of manual operation, especially when handling large or heavy bearings, improving the safety of operation. By driving the clamping block 6 through the telescopic part 5, the movement of the clamping block 6 can be precisely controlled, making the clamping process of the bearing seat more stable and reliable.
[0043] The working principle and use process of this utility model:
[0044] After the bearing seat is removed, use the appropriate ejection pad 32 according to the bearing diameter in the bearing seat to be removed, then place the bearing seat on the stepped circular groove 21, adjust the clamping block 42 to abut against the bearing seat, and then operate the locking nut 43 to apply force to the clamping block 42 to press the bearing seat, and under the transmission of the transmission member 31, lift the ejection pad 32 to contact the bearing and smoothly eject the bearing, and remove the bearing from the bearing seat. Finally, unlock the locking nut 43 and remove the bearing seat, and the separation operation is completed.
[0045] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
