Technical Field

[0001] This invention relates to the field of fixture technology, specifically a fixture for precision bearing machining. Background Technology

[0002] To meet the high demands of modern industry for precision bearing machining, it is imperative to develop a new type of fixture for precision bearing machining. This fixture should have stable and reliable fixing performance, good versatility, and convenient operation to improve the machining accuracy, quality, and production efficiency of precision bearings.

[0003] Patent application number 202221706185.4 relates to a novel fixing fixture for precision bearing machining, particularly a worktable and a bearing. A first cylinder is mounted on the worktable surface, and a first clamping plate is mounted on the end of the first cylinder. A second cylinder is mounted outside the first clamping plate, and a second clamping plate is mounted on the end of the second cylinder. A tray is slidably connected to the worktable surface. A rotating plate is rotatably connected to the outside of the second clamping plate. A circular rod is mounted on the end of the rotating plate away from the second clamping plate. A first square groove is formed on the side of the tray, and a second square groove is formed on the side of the worktable. A bearing is mounted on the worktable surface. The fixed clamping plate has two sliding grooves on the worktable surface, and sliding blocks are slidably connected inside the sliding grooves. In this application, the first clamping plate pushes the tray to drive the bearing for pre-fixation, and then the second clamping plate accurately fixes the bearing, reducing the friction between the bearing and the worktable surface during fixing and avoiding the friction affecting the precision of the bearing. However, this device is difficult to accurately position and guide when reinforcing precision bearings, which will cause inaccurate precision and insufficient stability in the machining of precision bearings. Therefore, a fixed fixture for precision bearing machining is proposed to solve the above-mentioned problems. Summary of the Invention

When the machining of the shaft is completed... After completion, the moving rod 1 moves, driving the scraper 1 to clean the table surface and collect the waste material into the collection box. This prevents waste material from damaging the machined shafts on the table after processing, improving the efficiency of the processing operation and the quality of the workpiece.

While cleaning and lubricating, the T-shaped rod drives the stirring rod to rotate and stir the lubricant, preventing sedimentation and stratification, maintaining the uniformity and stability of the lubricant, extending its service life, and improving the lubrication effect. The top of the inclined block is fixedly connected to the inner wall of the reinforcement table, the T-shaped rod is slidably connected to the inner wall of the lubrication box through a spring plate, and the circumferential surface of the rotating shaft is in contact with the inner wall of the lubrication box.

This precision bearing machining fixture utilizes the coordinated operation of a bidirectional threaded rod, a turntable, a first moving rod, a clamping plate, a second moving rod, a first fixed block, a first pulley, a guide plate, a first pressure plate, an elastic telescopic rod, and a second pressure plate. When the shaft to be machined is placed on the clamping table by a machine or worker, the clamping plate can be moved by a motor or turntable to clamp the shaft, preventing displacement due to cutting forces, vibrations, or other factors during machining.

At the same time, the pressure plate 411 presses against the processed shaft 3 during reinforcement. Meanwhile, the elastic telescopic rod 410 retracts and elastically clamps the shaft, preventing damage to the surface of the precision bearing. This helps to ensure the consistency of processing accuracy and quality, reduces dimensional deviations and surface quality differences caused by different clamping forces, and greatly improves processing efficiency.
