Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0029] Traditional vacuum pump bearing installation involves tapping the bearing with a rubber mallet and pressing it into position with a screw. This process generates metal shavings that can enter the bearing, damaging it during pump operation. Furthermore, uneven installation can lead to premature bearing wear.
[0030] This utility model provides a vacuum pump bearing mounting assembly for installing bearings inside a vacuum pump. It includes: a mounting base 1 with a mounting position 101; a support device 2 mounted on the mounting base 1; a pushing device 3 mounted on the support device 2; and a fixture 4 with a first contact surface 401 corresponding to the size of the bearing. The fixture 4 and the pushing device 3 cooperate to press and install the bearing into the mounting position 101. The mounting base 1 serves as the carrier for mounting the bearing, providing the mounting position 101 for bearing installation. The support device 2 supports the pushing device 3, which provides pushing force to press the bearing into the mounting position 101. The fixture 4 contacts the bearing to change its position. The correspondence between the first contact surface 401 of the fixture 4 and the bearing size means that the radius of the first contact surface 401 of the fixture 4 is the same as the radius of the bearing.
[0031] During implementation, the support device 2 is installed on the mounting base 1, the pushing device 3 is installed on the support device 2, the bearing to be installed is placed on the mounting position 101 of the mounting base 1, the first contact surface 401 of the fixture 4 is aligned with the bearing and placed on the bearing, the pushing device 3 is activated, the pushing device 3 provides a pushing force to the fixture 4, the fixture 4 gradually pushes the bearing, thereby realizing the push-press installation; the first contact surface 401 of the fixture 4 contacts the bearing, and the first contact surface 401 corresponds to the size of the bearing, the fixture 4 will completely cover the bearing. The advantage of complete coverage is that it can make the bearing stable under force during the pushing process, and always maintain a stable posture when being pushed and installed. Moreover, since it is completely covered, even if there are iron filings outside, the fixture 4 will block the iron filings outside the bearing, preventing the iron filings from falling into the bearing, thus ensuring the stability of the bearing after installation.
[0032] Furthermore, the support device 2 can be a bracket or a cylindrical support structure surrounding the mounting position 101, and the pushing device 3 can be a hydraulic jack, cylinder, or other device. The first contact surface 401 of the fixture 4 not only corresponds to the size of the pushing device 3, but also the shape of the first contact surface 401 corresponds to the shape of the bearing side. The mounting base 1 can be provided with multiple mounting positions 101, and a bearing can be installed on each mounting position 101.
[0033] In some embodiments, the mounting position 101 is provided with a fixing groove. The fixing groove is used to fix the bearing.
[0034] During implementation, the bearing is placed in the fixed groove on the mounting position 101, and the fixture 4 is then placed on the bearing. Under the push of the pushing device 3, the fixture 4 pushes the bearing into the fixed groove, where the bearing is fixed. In addition to fixing the bearing, the fixed groove can also limit the fixture 4, keeping the fixture 4 stable during the pushing process.
[0035] In some embodiments, the support device 2 includes: a bracket; a fixing member 201 having a first through hole and being installed at the bottom of the bracket; and a mounting base 1 having a second through hole, the first through hole and the second through hole being positioned and sized correspondingly. The bracket is the main component supporting the pushing device 3, and the fixing member 201 is used to fix the bracket.
[0036] During implementation, the fastener 201 is placed on the mounting base 1 and the first through hole is aligned with the second through hole. Screws and nuts are taken, and the screws are passed through the first through hole and the second through hole in sequence. The nuts are then tightened to fix the screws, thereby fixing the fastener 201 on the mounting base 1.
[0037] Specifically, the fastener 201 is provided with multiple first through holes, and the mounting base 1 is also provided with multiple second through holes. In this embodiment, the purpose of providing multiple first through holes and second through holes is to enable the fastener 201 to be fixed through two or more through holes at the same time. Another purpose is to facilitate changing the position of the fastener 201. Changing the position of the fastener 201 is equivalent to changing the position of the bracket, which also changes the pushing device 3, so that the pushing device 3 can be adapted to the fixture 4.
[0038] In some embodiments, the bracket includes a support beam 202 and a support rod 203, the support beam 202 and the support rod 203 are connected, one end of the support rod 203 is provided with threads, the fixing member 201 is provided with a screw hole, and the threads on the support rod are threadedly engaged with the screw hole on the fixing member.
[0039] In practice, the threaded end of the support rod 203 is inserted into the threaded hole of the fixing member 201, and the support rod 203 is rotated to lock it in the fixing member. Then, the support beam 202 is connected to the support rod 203, and the pushing device 3 is installed on the support beam 202 to support the pushing device 3 in sequence.
[0040] Furthermore, a support rod 203 is fixed on each side of the mounting base 1, and the middle part of the mounting base 1 is the mounting position 101. The support beam 202 is fixed between the two support rods 203, and the pushing device 3 is fixed on the support beam 202. The fixing member 201 is a square plate structure. In some cases, the fixing member 201 can also be a square structure.
[0041] In some embodiments, the support rod 203 is provided with an annular groove 204, and the support beam 202 is provided with a latch 205, wherein the latch 205 engages with the annular groove 204.
[0042] During implementation, align the slot 205 on the support beam 202 with the annular slot 204 on the support rod 203, and then snap the buckle into the slot to fix the support beam 202.
[0043] Specifically, two support rods 203 are provided, and the two support rods 203 have the same structure. Both of them are provided with annular grooves 204. Both ends of the support beam 202 are provided with slots 205. The slots 205 at both ends of the support beam 202 are respectively inserted into the annular grooves 204 of one of the support rods 203, thereby fixing the support beam 202 between the two support rods 203.
[0044] In some embodiments, the support beam 202 is provided with a fixing structure, and the pushing device 3 is a hydraulic jack, which is fixed to the support beam 202 by the fixing structure.
[0045] During implementation, a fixing structure is set on the support beam 202 to fix the hydraulic jack to the support beam 202, so that the hydraulic jack remains stable.
[0046] In some embodiments, the hydraulic jack includes a hydraulic cylinder 301 and a hydraulic oil tank 302, wherein the hydraulic cylinder 301 is connected to the hydraulic oil tank 302, and the hydraulic cylinder 301 is fixed on the fixed structure of the support beam 202.
[0047] During implementation, the hydraulic cylinder 301 is fixed on the fixed structure of the support beam 202, the hydraulic oil tank 302 is placed on the outside of the mounting base 1, the piston of the hydraulic cylinder 301 is aligned with the fixture 4, and the piston will push towards the fixture 4 after the hydraulic cylinder 301 is started.
[0048] In some embodiments, the fixing structure is a hole 206 provided on the support beam 202, and the hydraulic cylinder 301 is provided with a bushing 303, which is engaged in the hole 206.
[0049] During implementation, the hydraulic cylinder 301 is fixed in the hole 206 by the bushing 303, and the piston end of the hydraulic cylinder 301 is aligned with the fixture 4 with the bottom facing down.
[0050] Furthermore, the hole 206 is an elongated hole, that is, a hole-like structure with arc-shaped ends and two parallel straight lines in the middle. The bushing 303 is a cylindrical structure with an annular groove. The bushing 303 is fitted onto the hydraulic cylinder 301, and the annular groove on the bushing 303 is engaged with the edge of the hole 206. Since it is an elongated hole, the hydraulic cylinder 301 can move within the hole 206 through the bushing 303, thereby changing the position of the hydraulic cylinder 301. Because multiple mounting positions 101 are set on some mounting bases 1 to install multiple bearings, it is necessary to change the position of the hydraulic cylinder 301 to install bearings in different positions.
[0051] In some embodiments, holes 206 corresponding to the bearing size can be opened at different positions on the support beam 202. The position of the hydraulic cylinder 301 can also be changed by installing the hydraulic cylinder 301 at different positions of the holes 206.
[0052] In some embodiments, the fixture 4 is provided with a second contact surface 402, and the piston on the hydraulic cylinder 301 abuts against the second contact surface 402.
[0053] During implementation, the piston end of the hydraulic cylinder 301 contacts the second contact surface 402 during pushing, thereby pushing the fixture 4.
[0054] In some embodiments, the slot 205 on the support beam 202 is a one-way opening.
[0055] During implementation, align the opening with the annular groove 204 on the support rod 203, and then push the slot 205 of the support beam 202 into the annular groove 204 to achieve fixation.
