Description

Technical Field

[0001] This utility model belongs to the field of bearing press-fitting equipment technology, and more specifically, it relates to a bearing press-fitting device. Background Technology

[0002] In modern industrial manufacturing, bearings, as indispensable key components in mechanical equipment, are widely used in numerous industries such as automotive, aerospace, and machinery manufacturing. Their function is to reduce the coefficient of friction between moving parts during mechanical transmission, while ensuring the rotational accuracy of components, thus having a crucial impact on the performance, reliability, and service life of mechanical equipment. The quality of bearing press-fitting directly affects the operational stability and safety of the entire equipment. In actual production processes, precise and efficient bearing press-fitting is a key link in ensuring the normal operation of equipment. With the acceleration of industrial automation, traditional manual or simple tool press-fitting methods are no longer sufficient to meet the demands of large-scale, high-precision production. To improve production efficiency and ensure consistent product quality, the development of an automated, high-precision bearing press-fitting device has become an inevitable trend in industry development.

[0003] Based on the above, with the development of the modern bearing industry, bearings are indispensable in many equipment. Therefore, bearing press-fitting equipment has emerged. However, most modern bearing press-fitting equipment is for press-fitting one type of product, which leads to the single nature of the press-fitting equipment's work. This means that each different product needs to be equipped with a separate press-fitting device, and there are relatively few with protective devices. Utility Model Content

[0026] The conveyor belt 5 has a set of square grooves at the bottom, and a feeder 501 is telescopically connected in the square grooves at the bottom of the conveyor belt 5. The rear side of the feeder 501 is meshed with the rotating shaft on one side of the small motor 502. The feeder 501 can be telescopically extended and retracted through the connection of the small motor 502 to realize the automatic replacement of bearings.

[0027] Among them, a threaded rod 101 is fastened to the rotating shaft at the bottom of the pressure motor 1, and a pneumatic rod 102 is telescopically connected to the outside of the threaded rod 101; a set of circular connecting holes is provided on one side of the pneumatic rod 102, and the purpose of moving up and down is achieved by meshing the teeth on the outside of the threaded rod 101 and the teeth inside the pneumatic rod 102.

[0028] A set of air supply pipes 301 are fastened to the bottom connecting rod of the air intake machine 3, and the other side of the air supply pipes 301 is fastened to the circular connecting hole on one side of the air pressure rod 102.

[0030] Among them, the connecting shaft on the outside of the clamp 7 and the four sets of circular connecting tubes in the middle of the base 6 are connected by a set of limit springs 701. The design of the springs reduces the cost of the clamping device and enables faster operation.
