Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment, and in particular to an ultra-precision machine swing head with a double oilstone structure. 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 invention provides a double oilstone oscillating head for ultra-precision machining of bearing outer ring raceways, which can improve efficiency and effectively reduce costs.

[0004] To achieve the above objectives, this utility model provides a swivel head for ultra-precision machines with a double oilstone structure, including a base, on which two oilstone frames and an adjustment assembly are provided. The adjustment assembly includes a rotating seat, a driving component, and a transmission component. The two oilstone frames are circumferentially spaced on one side of the rotating seat. One end of the transmission component is connected to the driving component, and the other end of the transmission component is connected to the rotating seat. The transmission component can drive the rotating seat to rotate and switch the positions of the two oilstone frames under the action of the driving component.

[0005] The advantages of the above technical solution are: by setting a rotating seat with two oilstone holders on the base, and cooperating with an adjustment assembly including a drive component and a transmission component, the rotating seat rotates to switch between the two oilstone holders by driving the transmission component through the drive component. This enables the switching of two oilstone holders on the same equipment. It not only meets the ultra-high precision machining requirements of the bearing outer ring groove by using different combinations of oilstones, but also saves the need for handling and relocation between multiple machines, saves a lot of equipment space, and greatly improves production efficiency.

[0006] The present invention can be further configured such that: a semi-circular toothed portion is provided on the other side of the rotating seat, and the transmission component is in the shape of a rack and meshes with the toothed portion.

[0007] By further designing the rotating seat, a semi-circular toothed part is provided on the other side of the rotating seat, and the transmission component is designed as a rack and pinion to mesh with the toothed part. When the driving component drives the transmission component, the rotating seat can be driven to rotate smoothly through the precise transmission of the gear and rack, thereby realizing the switching of the two oilstone frames. Through the mechanical meshing transmission, the stability is strong and the response is rapid.

[0008] The present invention can be further configured such that: the rotating seat is provided with a rotating shaft and two bearings, the two bearings are respectively located at the upper and lower ends of the rotating seat, the rotating shaft passes through the rotating seat, and the upper and lower ends of the rotating shaft are respectively fixed to the inner holes of the two bearings, and the outer rings of the two bearings are positioned and fitted with the base.

[0009] By further configuring bearings at both ends of the rotating base, fixing the rotating shaft passing through the rotating base to the bearing inner hole, and positioning the bearing outer ring to the base, a stable rotating support structure is formed. This ensures that the rotation center of the rotating base is accurately fixed, the position of the oilstone frame is correct, and the stability of the product is guaranteed.

[0010] The present invention can be further configured such that: the base is provided with a long groove for the transmission component to slide therein, the driving component is fixed at one end of the long groove, the other end of the long groove is provided with a mounting clamp, and the transmission component extends into the mounting clamp and engages with the rotating seat.

[0011] By further designing the base, a long groove is provided for the transmission component to slide. The long groove also provides protection for the transmission component. The drive component is fixed to one end of the long groove, and a mounting clamp is provided at the other end of the long groove. This provides installation space for the meshing part of the transmission component and the rotating seat, and also provides protection and limit at the connection between the two, ensuring the stability of the product.

[0012] The present invention can be further configured as follows: a guide block is provided on the base, 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, and a protrusion is provided on the guide block, the protrusion being able to 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.
