Description

Technical Field

[0001] This utility model relates to the field of vacuum pump assembly technology, and in particular to a multi-angle automatic flipping mechanism for vacuum pump assembly lines, which is suitable for flipping workpieces at multiple angles during the assembly process to improve assembly efficiency and ease of operation. Background Technology

[0002] In the manufacturing process of vacuum pumps, the assembly stage has a decisive impact on the performance and reliability of the final product. Traditional vacuum pump assembly mainly relies on manual operation, especially in processes requiring multi-angle adjustments (such as bearing press-fitting, gearbox assembly, and clearance detection). Workers need to frequently manually rotate the pump body, which is not only labor-intensive but also time-consuming, making it difficult to match the production rhythm of modern assembly lines and restricting overall assembly efficiency. Manual operation is prone to workpiece position deviations; for example, incorrect angles during bearing press-fitting can cause coaxiality errors, affecting the stability of vacuum pump operation. Vacuum pump assemblies are usually heavy, and manual rotation poses risks of muscle injury or workpiece drops. Furthermore, relying on worker experience and operating methods makes it difficult to ensure process consistency, resulting in large fluctuations in the pass rate during mass production. In existing technologies, some manufacturers use simple rotating frames or hoisting equipment to assist assembly, but these still only support fixed angles (such as 90° or 180°) and cannot adapt to the flexible needs of complex processes. While overhead cranes or KBK cranes can move heavy objects, they lack precise angle control functions and still require manual intervention.

[0003] Therefore, there is an urgent need for an automated, high-precision, and production line-integratable tilting mechanism to solve the angle adjustment problem in vacuum pump assembly and achieve efficient, stable, and safe standardized operations. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and to provide a multi-angle automatic flipping mechanism for vacuum pump assembly lines that has a reasonable structural design and can achieve efficient, stable and safe operation.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: The multi-angle automatic flipping mechanism for vacuum pump assembly lines is characterized by the following: it includes a gantry frame, a lifting device, a clamping device, and a rotating device. The gantry frame includes a column and a top beam. The top beam is fixed to the top of the column, and the bottom of the column is fixed to the ground with bolts. The lifting device includes a limiting plate, a slider, a top plate, a bottom plate, a slider connecting block, a first servo motor, and a lifting guide rail. The top plate is fixed to the top beam with bolts, and the lifting guide rail passes through the top plate. The limiting plate and the bottom plate are respectively fixed to the top and bottom of the lifting guide rail. The slider connecting block and the first servo motor are both mounted on the top plate. The slider is mounted on the slider connecting block, and the slider cooperates with the lifting guide rail. The first servo motor is connected to the slider through a coupling. The clamping device includes a clamping arm, a gear and rack mechanism, and... The second servo motor and mounting bracket are mounted on the mounting bracket, with the top of the mounting bracket fixed to the bottom of the base plate. The gear and rack mechanism is a bidirectional screw clamping mechanism. Both the gear and rack mechanism and the second servo motor are mounted on the mounting bracket and connected to the gear and rack mechanism. The upper end of the clamping arm is movably mounted on the mounting bracket and connected to the gear and rack mechanism. The clamping arm is driven by the second servo motor, and the gear and rack mechanism is used to realize the retraction and extension of the clamping arm. The rotating device includes a drive shaft, a third servo motor, a worm gear reducer, and a clamping rotating block. Both the drive shaft and the third servo motor are mounted on the mounting bracket. The third servo motor is connected to the drive shaft via a coupling.
