Description

Technical Field

[0001] The present invention relates to the technical field of gear installation, in particular to a gear centering assembly device. Background Art

[0002] The core function of the gear centering assembly device is to achieve precise centering and secure clamping of the gear through mechanical structures or elastic elements, ensuring the coaxiality of the gear and shaft during assembly, thereby improving assembly accuracy, product quality, and production efficiency. When installing the shaft on the gear, a buffer block needs to be installed between the shaft and the pressing device, mainly to protect the accuracy of the gear and shaft and ensure assembly stability. In the existing method of installing the rotating shaft on the gear, the rotating shaft is not accurately positioned and guided. During the pressing process, the rotating shaft is prone to tilting, causing damage to both the rotating shaft and the gear hole wall, affecting the product quality of the gear. At the same time, when installing the rotating shaft on the gear, it is usually necessary to apply lubricating oil to reduce the friction coefficient between the rotating shaft and the gear hole wall, making the pressing process smoother. However, the existing method of applying lubricating oil to the gear hole wall is prone to causing excessive lubricating oil to be applied to the gear hole wall. The rotation of the rotating shaft will stir the oil, generating additional viscous resistance, resulting in increased energy consumption for subsequent driving of the gear. Summary of the Invention

[0003] The technical problems solved by this solution are: (1) How to solve the problem of excessive lubricating oil on the gear hole wall, which will cause the rotation of the shaft to stir the oil, generate additional viscous resistance, and increase the energy consumption of the subsequent driving gear; (2) How to solve the problem that the shaft is prone to tilting during the pressing process, causing damage to the shaft and the gear hole wall, thus affecting the quality of the gear product.

[0004] The objectives of the present invention can be achieved through the following technical solutions: A gear centering assembly device includes an assembly table, a housing is fixedly mounted on the top of the assembly table, and a positioning block for limiting the gear is fixedly mounted on the top of the assembly table, an alignment mechanism for guiding the rotating shaft is provided on one side of the positioning block, and a lubrication mechanism for applying lubricating oil to the gear hole wall is provided below the positioning block; The lubrication mechanism includes a storage cavity opened inside the assembly table, and the storage cavity is filled with a sufficient amount of lubricating oil.

The position of the first perforation corresponds to the position of the gear hole, and a loading unit for applying lubricating oil is provided above the first perforation.

[0005] A further technical improvement of the present invention is that the loading unit includes a longitudinally arranged connecting rod, a support block for positioning the rotating shaft is fixedly installed on the top of the connecting rod, the size of the support block is smaller than the diameter of the rotating shaft, a sponge cover is fixedly installed in the middle of the connecting rod, the diameter of the sponge cover is larger than the gear aperture, and the inner diameter of the first perforation and the gear aperture are both larger than the diameter of the connecting rod.

[0006] A further technical improvement of the present invention is that a first sealing ring is fixedly installed on the top of the inner wall of the first through-hole, and the first sealing ring is in contact with the gear; a second sealing ring is fixedly installed inside the second through-hole; and a longitudinally arranged first cylinder is fixedly installed on the bottom of the assembly table through a support plate.

[0008] A further technical improvement of the present invention is that: an oil supply tool is fixedly provided on the top of the support plate, the oil supply tool is a prior art, and the output end of the oil supply tool is connected with an oil inlet pipe, the output end of the oil inlet pipe is fixedly passed through the storage cavity, and an oil detection meter for monitoring the amount of lubricating oil therein is provided inside the storage cavity, and the oil detection meter is a prior art; by controlling the extended end of the first cylinder to shrink from the longest to the shortest, the connecting rod drives the support block and the sponge sleeve to pass through the first perforation and enter the storage cavity, and the support block and the sponge sleeve are immersed in the lubricating oil, and then the control is carried out. The extended end of the first cylinder is reset and stretched to its longest position, and then retracted to its shortest position. During this process, a sponge sleeve that absorbs lubricating oil passes through the gear hole wall, ensuring that the gear hole wall is evenly coated with lubricating oil. The excess lubricating oil is scraped off by the sponge sleeve and flows back into the storage cavity along the first perforation, avoiding excessive application of lubricating oil and generating additional viscous resistance, which leads to increased energy consumption in the subsequent driving gear operation. At the same time, when the support block rises and resets to the highest position, the lubricating oil remaining on the surface of the support block will adhere to the bottom end of the rotating shaft, further preventing damage to the rotating shaft and the gear hole wall.

[0011] A further technical improvement of the present invention is that: two second guide wheels are rotatably provided on the inner wall of the outer shell, and the positions of the two second guide wheels correspond to the positions of the two first guide wheels respectively; by controlling the protruding end of the second cylinder to extend from the shortest to the longest, the connecting plate drives the two first guide wheels to be rollingly connected with the rotating shaft. At this time, the rotating shaft is fixed and guided by the two first guide wheels and the two first guide wheels. In this process, the flip arm is driven to rotate by the shift rod, so that the clamping block moves to be close to the gear, and the gear is limited by the clamping block and the positioning block to prevent tilting during the pressing and installing of the rotating shaft, avoid damage to the rotating shaft and the gear hole wall, and affect the product quality of the gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is in use, the protruding end of the first cylinder is controlled to shrink from the longest to the shortest, so that the connecting rod drives the support block and the sponge sleeve to pass through the first perforation and enter the storage chamber, and the support block and the sponge sleeve are immersed in lubricating oil. Then the protruding end of the first cylinder is controlled to reset and extend to the longest, and then shrink to the shortest.
