Detailed Implementation
[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Examples, such as Figures 1-4As shown, an auxiliary support device for a precision bearing machining ultra-precision machine includes an ultra-precision machine body, which comprises a frame 1, a chuck assembly 2, and a laterally adjustable top-loading assembly 3. The arrangement of these components is standard for existing ultra-precision machine bodies, and the specific components are readily known to those skilled in the art; therefore, further details are omitted. This embodiment aims to address the shortcomings of existing ultra-precision machines in providing auxiliary and stable support for workpieces during operation. Specifically, a laterally adjustable base 4 is provided on one side of the top-loading assembly 3. The lateral movement of this base is coordinated with the top-loading assembly... 3. The same method of movement adjustment using a lead screw mechanism ensures that it can be close to the workpiece, providing convenient conditions for subsequent auxiliary support of the workpiece. A longitudinal movement component 5 is provided above the machine base 4. The longitudinal movement component 5 includes a longitudinal plate that can be moved and adjusted relative to the machine base 4. The two can move relative to each other, providing a prerequisite for driving the base 6 to correspond with the chuck assembly 2, thereby ensuring subsequent auxiliary support of the workpiece and meeting the usage requirements. Furthermore, a base 6 is provided above the longitudinal movement component 5. A mounting seat 7 is provided on one side of the upper part of the base 6. A mounting tube 8 is provided on one side of the mounting seat 7. A T-shaped connecting rod 9 is provided inside the mounting tube 8, connecting... An adjustable locking mechanism 10 is provided on one side of the rod 9. A first bearing 11 that rotates longitudinally is provided on the outer side of the locking mechanism 10, and a second bearing 12 that rotates laterally is provided on the outer side of the mounting tube 8. In use: First, select a suitable first bearing 11 according to the specifications and dimensions of the workpiece to be processed. Then, use the locking mechanism 10 to install the first bearing 11 on the connecting rod 9 and tighten it. At the same time, connect the above equipment to the mounting tube 8. After the connection is completed, adjust the position of the second bearing 12 according to the specifications and dimensions of the workpiece so that its outer circumference is flush with the outer end face of the workpiece, which to a certain extent prevents the workpiece from jumping. Then, the chuck assembly 2 is used to clamp the workpiece, and the position of the first bearing 11 in the longitudinal direction is adjusted so that it corresponds to the workpiece to be processed. Before starting work, the position of the first bearing 11 is adjusted, especially so that its outer periphery can be relatively close to the inner side wall of the workpiece, which can provide a certain degree of limit. At the same time, the outer periphery of the second bearing 12 is in contact with the outer end face of the workpiece. In this way, when the outer periphery of the workpiece is being ultra-precision machined, both the first bearing 11 and the second bearing 12 can rotate with the workpiece as it rotates. While providing auxiliary support for the workpiece, it also ensures the smoothness of the workpiece production process and meets the usage requirements.
[0020] In the above process: the locking mechanism 10 is used to secure the first bearing 11 of different specifications and sizes, reducing the possibility of displacement. This provides convenient conditions for adapting to the inner side of workpieces of different specifications. It is simple to operate, highly functional, and ensures the forming quality of the workpiece, meeting the usage requirements. The second bearing 12 is used, and its position can be adjusted according to the specifications and size of the first bearing 11 to be installed, ensuring that it can abut against the outer end face of the workpiece, further playing an auxiliary support role, ensuring the stability of the workpiece, and meeting the usage requirements. This device is reasonably designed, simple in structure, easy to process, and can achieve convenient and stable positioning of the workpiece, reducing the possibility of damage and ensuring the forming quality of the workpiece. At the same time, it can be quickly adjusted for workpieces of different specifications and sizes, improving the work process, saving time and costs, and meeting the usage requirements.
[0021] To accommodate different sizes of first bearings 11 and ensure smooth subsequent processing, the locking mechanism 10 includes a longitudinally arranged slide bar 101 on one side of the connecting rod 9. Two slide bars 101 are equipped with wedge-shaped sliders 102 that are longitudinally adjustable. A limit rod 103 is located on the connecting rod 9 between the two sliders 102. An isosceles trapezoidal abutment block 104 is mounted on the limit rod 103. A rotating screw 105 is housed within the abutment block 104. The connection between the abutment block 104 and the rotating screw 105 is similar to the connection between a lead screw and a lead screw nut in the prior art. Thus, when the rotating screw 105 is rotated, it can drive the abutment block 104 relative to the limit rod 103. The movement is specifically described as follows: First, a first bearing 11 that can be matched with the inner shaft of the workpiece to be processed is selected. Then, the first bearing 11 is placed outside the locking mechanism 10. Then, the rotating screw 105 is rotated so that the clamping block 104 acts on the slider 102 and ensures that the outer periphery of the clamping block 104 matches the inner surface of the first bearing 11 until the slider 102 completes the fastening of the first bearing 11, ensuring the stability of its position. In this way, when the first bearing 11 matches the inner surface of the workpiece, the stability of the workpiece during the processing can be ensured. At the same time, the first bearing 11 can also rotate with the workpiece, ensuring the smoothness of the workpiece processing, improving the workpiece processing progress, and having strong adaptability to meet different usage needs.
[0022] To accommodate workpieces of different sizes and specifications, and especially to ensure stability during the processing of workpiece end faces, a slot 81 is provided on the outer side of the mounting tube 8. A mounting plate 13 is installed within the slot 81. A T-shaped plate 14 is provided on one side of the mounting plate 13. A transverse groove 131 is provided within the mounting plate 13 above the T-shaped plate 14. A movable seat 15 is provided on the outer side of the T-shaped plate 14. The movable seat 15 is also T-shaped and fits the T-shaped plate 14. An extension plate is also provided above the movable seat 15, corresponding to the transverse groove 131. This design ensures the convenience and stability of the movable seat 15 during movement, guaranteeing its functionality. A telescopic rod is provided on the outer side of the movable seat 15. 16, and connected to the second bearing 12, the telescopic rod 16 can adjust the second bearing 12 in the longitudinal direction to ensure that it can fit against the workpiece. The mounting plate 13 is provided with a fastening screw 17 that locks the moving seat 15. In use: according to the workpiece of different specifications and sizes, the corresponding first bearing 11 is selected and fixed. Then, according to the end face position of the workpiece after placement, the position of the second bearing 12 is adjusted, especially to ensure that its outer circumference can abut against the outer end face of the workpiece. In this way, the equipment can effectively complete the auxiliary support of the workpiece to be processed, reduce the possibility of its displacement, ensure the stability of the workpiece production and processing process, and guarantee the forming quality of the workpiece.
[0023] To facilitate convenient installation of the equipment and ensure its stability, a limiting strip 82 is provided inside the mounting tube 8, and a limiting groove 91 is provided inside the connecting rod 9 corresponding to the limiting strip 82. A locking screw 92 is provided on the outside of the mounting tube 8 and abuts against the outer periphery of the connecting rod 9. Specifically, when installing the connecting rod 9, the limiting groove 91 is aligned with the limiting strip 82, and the connecting rod 9 is inserted into the mounting tube 8. Of course, in this embodiment, the limiting strip 82 and the limiting groove 91 are rectangular in shape. The shape can be set to T-shape or dovetail shape, etc., to further improve the tightness of the fit between the devices. After the connecting rod 9 is connected to the mounting tube 8, the locking screw 92 is used to position and tighten the connecting rod 9 to ensure its stability and meet the usage requirements.
[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
