Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment, and in particular to a double-oilstone structure swing head with a positioning component. Background Technology

[0002] In the manufacturing of deep groove ball bearings, the ultra-precision machining of the outer ring raceway is a key process that determines the bearing's accuracy, noise level, and service life. With the increasing demands for bearing precision in the industrial sector, especially in high-end equipment manufacturing, customers are placing more stringent requirements on the surface roughness (Ra) and total profile deviation (Pt) of the bearing's outer ring raceway. Existing technologies, relying solely on single-stage, single-stone machining, often fall short of these requirements, forcing manufacturers to adopt a step-by-step machining approach: first, a basic abrasive stone is used on one machine to complete the initial ultra-precision machining; after the workpiece is machined, it must be manually unloaded from this machine and transported to another machine equipped with a higher-precision abrasive stone for secondary finishing. This machining mode has particularly prominent limitations in mass production scenarios: on the one hand, the purchase, installation, and daily maintenance of the two machines require significant investment, significantly increasing production costs; on the other hand, the multiple transfers of the workpiece between the two machines not only extend the production cycle and reduce output efficiency per unit time, but may also affect the stability of machining accuracy due to collisions and positioning deviations during transport. Therefore, further development of existing technologies is necessary. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a double oilstone structure swing head with a positioning component, which can switch oilstones and ensure the positioning and stability of the oilstone frame after switching.

[0004] To achieve the above objectives, this utility model provides a double oilstone structure swing head with a positioning component, including a base, on which two oilstone frames, a rotating seat, and a positioning component are provided. The rotating seat is rotatably configured, and the two oilstone frames are circumferentially spaced on one side of the rotating seat. The positioning component includes a lifting pressure rod, and the oilstone frames are provided with limit grooves. The end of the pressure rod is provided with a locking head, which can extend into the limit groove and abut against the inner wall of the limit groove.

[0005] The advantages of the above technical solution are: by setting two oilstone frames on the base that can be switched by rotating the rotating seat, a large amount of equipment space can be saved and production efficiency can be greatly improved. In addition, a lifting pressure bar and a limiting groove are set up, which can adjust the switchable state and the positioning state of the two oilstone frames after the lifting pressure bar is used. When the oilstone frame is switched to the working position with the rotating seat, the pressure bar descends and the end clamp extends into the limiting groove and abuts against the inner wall of the groove to achieve limiting and fixing, and ensure stability.

[0006] The present invention can be further configured such that: the pressure rod includes an inclined section extending downward, and the clamp head extends horizontally.

[0007] By further designing the lever, the inclined section extends downwards to make way, and then the locking head extends horizontally to fully enter the limiting groove, ensuring the limiting effect through sufficient contact area.

[0008] The present invention can be further configured such that: the positioning component includes a guide post, the guide post is positioned at the middle position of the pressure rod, the guide post and the pressure rod are slidably inserted into each other, and the guide post extends in the direction of lifting and lowering of the pressure rod.

[0009] By further configuring the guide post in the middle of the pressure rod, and by slidably inserting the guide post into the pressure rod and extending it along the lifting direction, the lifting movement of the pressure rod is guided, so that the pressure rod will not swing or slip during the lifting process, thereby ensuring that the clamp can be accurately inserted into the limiting groove.

[0010] The present invention can be further configured such that: the positioning component includes a limiting frame, the limiting frame is disposed on both sides of the pressure rod and forms a sliding abutment with the pressure rod, and the limiting frame is disposed near the guide post.

[0011] By further configuring the limit brackets on both sides of the pressure rod and near the guide post, and making them slide against the pressure rod, the guidance of the pressure rod is further enhanced. Furthermore, the limit brackets are positioned near the guide post, allowing the guide post to slide and guide from the middle of the pressure rod, while the limit brackets form lateral limits from both sides of the pressure rod.

[0012] The present invention can be further configured such that: the positioning component includes a guide block, an arc-shaped notch is provided on the other side of the rotating seat, the guide block is provided on the other side of the rotating seat, the guide block is provided with a protrusion, and the protrusion can slide along the bottom of the arc-shaped notch and abut against the two end faces of the arc-shaped notch.

[0013] By further designing the rotating seat, an arc-shaped notch is provided on the other side, along with corresponding guide blocks and their protrusions, guiding and limiting the rotation of the rotating seat. When the rotating seat drives the oilstone frame to switch positions, the protrusions on the guide blocks slide along the bottom of the arc-shaped notch to provide guidance. When the rotating seat is switched into position, the protrusions abut against the two end faces of the arc-shaped notch to form a limit, ensuring the stability of the product.
