Description

Technical Field

[0001] This utility model belongs to the field of hem machine processing technology, specifically relating to a highly waterproof hem machine upper shaft bearing assembly structure. Background Technology

[0002] The pendulum-type optical lens polishing machine, commonly known as the pendulum machine, is a commonly used optical processing equipment. It adopts the quasi-spherical center principle, which makes the spindle rotate at high speed while reciprocating around the pendulum axis. It is used in conjunction with a polishing slurry containing abrasive particles and corrosive chemical agents, and achieves fine grinding, surface polishing and processing of optical lenses through the principle of mechanochemical polishing.

[0003] In traditional methods, when using a lower-swing machine to process lenses, the pressure head on the upper shaft presses against the spherical surface of the lens during grinding and rotation. The cutting fluid during processing can easily be carried into the bearing assembly through the gaps in the shaft core, causing wear, oxidation, and rust on the bearing. This can directly lead to a shortened bearing life and uneven rotation, affecting processing quality and work efficiency. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide an upper shaft bearing assembly structure for a swing-down machine. This assembly includes an upper main shaft, a waterproof sleeve, a water-blocking cover, and a pressure unit. The upper main shaft comprises a main shaft and a secondary shaft. The waterproof sleeve is fitted onto both the main shaft and the secondary shaft. The water-blocking cover and the pressure unit are sequentially connected to the waterproof sleeve and fitted onto the secondary shaft. A first sealing ring is provided at the connection point between the waterproof sleeve and the main shaft, and a second sealing ring is provided at the connection point between the waterproof sleeve and the secondary shaft. The upper main shaft can be inserted onto the machine tool for processing. By incorporating a waterproof sleeve into the bearing assembly structure of the swing-down machine, and by having the waterproof sleeve fitted onto the upper shaft via the first and second sealing rings, the risk of water entering the machine during processing is reduced. Simultaneously, the water-blocking structure of the water-blocking cover prevents liquid splashing, thereby improving processing quality and operational efficiency.

[0005] This utility model is achieved through the following technical solution:

The water baffle and the pressure unit are sequentially connected to the waterproof sleeve and fitted onto the secondary shaft. A first sealing ring is provided at the joint between the waterproof sleeve and the main shaft, and a second sealing ring is provided at the joint between the waterproof sleeve and the secondary shaft.

[0008] Specifically, a screw hole is provided at the end of the secondary shaft away from the main shaft, and the pressure head connecting rod is fixed to the secondary shaft by a bolt. In order to improve the fixing effect of the pressure head connecting rod, a washer can also be provided at the fixing position of the bolt and the screw hole.

[0009] Optionally, the pressure unit is further provided with a rubber plug, which seals the bolt. This ensures that the liquid during processing enters the shaft body.

[0010] In one embodiment, the waterproof sleeve, the water-blocking cover, and the portion of the pressure unit that is sleeved with the secondary shaft form a cavity, and a plurality of bearings are disposed in the cavity, the bearings being sleeved on the secondary shaft.

[0011] In one embodiment, an outer bearing support and an inner bearing support may be provided between the plurality of bearings.

[0012] In one embodiment, the cavity further includes a bearing cover, which is fitted onto the secondary shaft and can also cover the bearing for fixing the bearing.

[0021] Please see Figure 1 This utility model embodiment provides a lower swing machine upper shaft bearing assembly structure, including an upper main shaft 1, a waterproof sleeve 2, a water baffle 3, and a pressure unit 4. The upper main shaft 1 includes a main shaft 10 and a secondary shaft 11. The waterproof sleeve 2 is sleeved on the main shaft 10 and the secondary shaft 11. The water baffle 3 and the pressure unit 4 are sequentially connected to the waterproof sleeve 2 and sleeved on the secondary shaft 11. A first sealing ring 20 is provided at the joint between the waterproof sleeve 2 and the main shaft 10, and a second sealing ring 21 is provided at the joint between the waterproof sleeve 2 and the secondary shaft 11.

The main shaft 10 of the upper spindle is inserted into the machine base to play a fixed and limiting role. It can be connected to the machine base structure by providing threads on the main shaft 10. By providing a first sealing ring 20 at the sleeve part between the waterproof sleeve 2 and the main shaft 10, the cutting fluid can be prevented from flowing in from the upper shaft during processing.

[0023] To further improve the waterproof effect of the upper spindle 1, a second sealing ring 21 is provided on the part of the secondary spindle 11 that fits with the waterproof sleeve 2.

The inner bearing support 53 is sleeved on the secondary shaft 11, and the outer bearing support 52 is sleeved on the inner bearing support 53, for supporting the operation of the bearings 51.

[0033] Preferably, there are three bearings 51, which are respectively located in the cavities of the waterproof sleeve 2, the water-blocking cover 3, and the pressure unit 4.

[0034] In one embodiment, the cavity 5 further includes a bearing cover 54, which is sleeved on the secondary shaft 11 and can also cover the bearing 51 to limit the bearing 51.

[0035] In one embodiment, the water-blocking cover 3 is provided with an annular baffle 31, which can prevent liquid from splashing onto the machine body during processing and reduce the risk of water erosion of the machine.

[0036] This utility model discloses an upper shaft bearing assembly structure for a swing-down machine, including an upper main shaft 1, a waterproof sleeve 2, a water-blocking cover 3, and a pressure unit 4. The upper main shaft 1 includes a main shaft 10 and a secondary shaft 11. The waterproof sleeve 2 is fitted onto the main shaft 10 and the secondary shaft 11. The water-blocking cover 3 and the pressure unit 4 are sequentially connected to the waterproof sleeve 2 and fitted onto the secondary shaft 11.
