Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, specifically to a device for initial grinding of the cylindrical surface of bearing rolling elements. Background Technology

[0002] In the bearing manufacturing industry, the machining quality of bearing rolling elements directly affects the performance and service life of the bearing. Bearing rolling elements require multiple grinding steps during machining to ensure dimensional accuracy and surface finish.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Traditional methods for grinding bearing rolling elements typically include manual grinding or grinding using simple mechanical devices. These methods suffer from problems such as low efficiency, low grinding precision, and high labor intensity.

[0005] Manual polishing relies heavily on the skill and experience of the operator, resulting in slow polishing speeds and inconsistent polishing quality due to human error. While simple mechanical polishing devices improve polishing efficiency to some extent, they often lack flexibility, are difficult to adapt to bearing rolling elements of different sizes and shapes, and still require a high level of technical skill from the operator. Utility Model Content

[0006] The purpose of this invention is to provide a device for initial grinding of the cylindrical surface of bearing rolling elements, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for initial grinding of the cylindrical surface of bearing rolling elements, which mainly consists of a bottom fixed frame. Two mounting plates, a first mounting plate and a second mounting plate, are installed above the bottom fixed frame. A first slide rail is provided on the surface of the first mounting plate, and a lifting support device is installed on this first slide rail. The top of the lifting support device is designed with a placement groove for placing the bearing rolling elements.

[0008] A second slide rail is provided on the surface of the second mounting plate, extending perpendicularly to the first slide rail. A support plate is mounted on the second slide rail, and a fixing seat is fixed above the support plate. A grinding wheel is mounted on the top of the fixing seat, with a grinding wheel mounted on the drive end of the grinding wheel. The grinding wheel is used to grind the rolling elements of the bearing placed in the placement groove.

[0009] For ease of operation, four handles are designed on the outer end of the bottom mounting frame. These handles are arranged in pairs on the front and rear sides of the bottom mounting frame, making it convenient for users to move the device. The lifting and supporting device is more ingeniously designed, consisting of a fixed frame, an electric push rod, and a lifting platform. The fixed frame can slide on the first slide rail, the electric push rod is mounted on the upper side of the fixed frame, and the lifting platform is mounted on the upper end of the electric push rod. The placement slot is located on the top of the lifting platform for placing the bearing rolling elements.

[0010] To ensure the stability of the bearing rolling elements during grinding, clamps are designed within the placement groove to securely hold the rolling elements and prevent them from moving during grinding. An electric actuator is installed below the support plate, which controls the support plate to slide along the second slide rail. The bottom end of the electric actuator is fixed to the second mounting plate, ensuring stable operation of the support plate.

[0011] To further improve grinding precision, the mounting base is designed to be longitudinally adjustable. This design allows users to slightly adjust the height of the grinder as needed to accommodate the grinding requirements of bearing rolling elements of different sizes. Furthermore, to ensure safety and reliability during the grinding process, the entire device is equipped with appropriate safety features, such as a protective cover and an emergency stop button, to prevent accidents. The overall design of the device fully considers both ease of operation and grinding precision, effectively improving the grinding efficiency and quality of bearing rolling elements.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by using the lifting bearing device and the grinding wheel together, the bearing rolling elements can be ground quickly, improving production efficiency; the clamping block fixes the bearing rolling elements, ensuring that the rolling elements are stable in position during the grinding process, thereby improving the grinding accuracy.

[0013] The electric drive controls the bearing plate to slide along the slide rail, allowing the grinding wheel to be easily positioned to adapt to the grinding needs of bearing rolling elements of different sizes; the lifting bearing device allows the operator to easily adjust the height of the bearing rolling elements, simplifying the operation process and reducing labor intensity.

[0014] The reasonable layout design makes the device compact and space-saving; the use of electric push rods and electric drives makes maintenance and replacement of parts more convenient and quick; the design of the bottom fixing frame and handle ensures the stability of the device during use and prevents the equipment from moving.

[0015] The mounting base is longitudinally adjustable, which allows for fine-tuning of the height of the grinding wheel to accommodate the grinding needs of bearing rolling elements of different thicknesses. Attached Figure Description
