Description

Technical Field

[0001] This utility model relates to a floating pressure material vibration structure. Background Technology

[0002] In precision grinding, polishing, or deburring processes, a "floating pressure plate" method is often used to maintain flexible contact between the grinding head and the workpiece in order to improve the surface accuracy of the target object and avoid overcutting. Existing floating pressure plate mechanisms typically consist of a fixed base, a spring or elastic washer, a guide post, and a grinding head. During operation, the spring presses the grinding head against the workpiece surface through preload; when there are height differences or contour errors in the workpiece, the grinding head can float up and down along the guide post for adaptive adjustment. However, this type of floating pressure plate mechanism can only achieve single-degree-of-freedom floating, and the reset accuracy is easily reduced due to spring fatigue. Furthermore, it has high rigid coupling, making it difficult to simultaneously meet the requirements of multi-directional self-adaptation, high reset accuracy, and compact layout.

[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0004] In view of this, the present application provides a floating pressure vibrating structure to solve at least one problem existing in the prior art, comprising: The mounting mechanism includes a mounting plate, an extension plate extending downward around the perimeter of the mounting plate, and a plurality of spherical abutments. The lower end of the extension plate is provided with a limiting part. The mounting plate, the extension plate, and the limiting part form a semi-enclosed mounting space. The plurality of spherical abutments are located within the mounting space. A floating mechanism includes a connecting plate located within the installation space, a connecting rod perpendicular to and passing through the connecting plate, and a grinding head connected to the lower end of the connecting rod. The grinding head is configured to drive the connecting plate to move within the installation space when it is pressed against and subjected to the force of the target object. The floating mechanism has a first state of not being in contact with the target and a second state of being subjected to the force of the target; In the first state, the connecting plate abuts against the limiting part; In the second state, the connecting plate moves within the installation space under the action of the plurality of spherical abutments.

[0005] Optionally, in the above-described floating pressure vibrating structure, at least two spherical abutments are provided on each side wall of the installation space.

[0006] Optionally, in the above-described floating pressure vibration structure, the spherical support member includes a mounting base and a ball. The mounting base has a groove adapted to the ball, and a first bearing is disposed in the groove. The ball is at least partially located in the groove and is capable of rotating relative to the conveying mounting base under the action of the first bearing.

[0007] Optionally, the above-mentioned floating material vibration structure further includes a guide sleeve sleeved on the outside of the connecting rod, and the grinding head can drive the connecting rod to move up and down along the guide sleeve.

[0008] Optionally, in the above-described floating pressure vibration structure, the floating mechanism further includes a transition plate located between the connecting plate and the grinding head, and a force sensor is disposed between the transition plate and the connecting plate.

[0009] Optionally, in the above-described floating pressure vibration structure, the floating mechanism further includes a vibration motor disposed inside the grinding head.

[0010] Compared with the prior art, this application has the following advantages: By setting several spherical abutment members in the installation space, the connecting plate can achieve small displacement and tilting in various directions in the semi-enclosed installation space when subjected to the force of the target object. Compared with the traditional single-degree-of-freedom spring guide structure, it can automatically adapt to complex curved surfaces or local warping. In the first state, the connecting plate is precisely limited by the limiting part, and the spherical abutment members only provide low-friction rolling support, without spring fatigue or creep problems. The reset position is determined by mechanical hard limit, resulting in high consistency in batch processing. In the second state, the connecting plate moves in the "rolling-floating" support formed by the spherical abutment members, and the grinding head and the workpiece are flexibly coupled. When the target object is suddenly lifted, the grinding head can instantly retract to avoid impact damage while maintaining a constant pressure force. Attached Figure Description

[0016] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0017] Please refer to Figures 1-3 As shown in the preferred embodiment of this application, a floating pressure vibratory structure is used to grind a target object to make its surface flat. The floating pressure vibratory structure includes a mounting mechanism 1 and a floating mechanism 2. The mounting mechanism 1 includes a mounting plate 11, an extension plate 12 extending downwards around the mounting plate 11, and a plurality of spherical abutment members 13. A limiting portion 14 is provided at the lower end of the extension plate 12. The mounting plate 11, the extension plate 12, and the limiting portion 14 form a semi-enclosed mounting space 15, within which the plurality of spherical abutment members 13 are located. The floating mechanism 2 includes a connecting plate 21 located within the mounting space 15, a connecting rod 22 perpendicular to and passing through the connecting plate 21, and a grinding head 23 connected to the lower end of the connecting rod 22. The grinding head 23 is configured to move the connecting plate 21 within the mounting space 15 when it abuts against a target object and is subjected to the force of the target object. The floating mechanism 2 has a first state of no contact with the target object and a second state of being subjected to the force of the target object. In the first state, the connecting plate 21 abuts against the limiting portion 14. In the second state, the connecting plate 21 moves within the mounting space 15 under the action of the plurality of spherical abutment members 13.

[0018] Understandably, by providing several spherical support members 13 within the semi-enclosed installation space 15, the connecting plate 21 can be slightly adjusted in any direction within the installation space 15 when the floating mechanism 2 is in the second state, so as to adapt to the complex curved surface of the target object and reduce the risk of jamming and overcutting.

[0019] Understandably, when the floating mechanism 2 is in the first state, the limiting part 14 and the connecting plate 21 are mechanically and rigidly limited to ensure that the center position of the grinding head 23 is always consistent under no external force, and there is no reset drift during long-term operation. In addition, the spherical support 13 only provides rolling support and will not cause fatigue problems of elastic elements.

[0020] Furthermore, at least two spherical abutment members 13 are provided on each side wall of the installation space 15 to form multi-point rolling support, so that the connecting plate 21 is subjected to uniform force and floats more smoothly. In addition, at least two spherical abutment members 13 are distributed on each side wall, thereby increasing the effective contact area, reducing the single-point contact stress of the spherical abutment member 13, and improving the service life of the spherical abutment member 13.

[0021] Furthermore, the spherical support member 13 includes a mounting base 131 and a ball 132. The mounting base 131 has a groove adapted to the ball 132, and a first bearing (not shown) is disposed in the groove. The ball 132 is at least partially located in the groove and is capable of rotating relative to the conveying mounting base 131 under the action of the first bearing. The purpose of this arrangement is that the ball 132 rotates with low friction within the groove of the mounting base 131 via the first bearing, significantly reducing the resistance of the connecting plate 21 and improving the floating sensitivity and response speed.

[0022] Furthermore, the floating pressure vibration structure also includes a guide sleeve 3 sleeved on the outside of the connecting rod 22, and the grinding head 23 can drive the connecting rod 22 to move up and down along the guide sleeve 3.

[0023] Furthermore, the floating mechanism 2 also includes a transition plate 24 located between the connecting plate 21 and the grinding head 23. A force sensor 25 is provided between the transition plate 24 and the connecting plate 21 to detect the actual pressure between the grinding head 23 and the target object, so as to prevent overpressure damage or underpressure grinding failure.

[0024] Furthermore, the floating mechanism 2 also includes a vibration motor 26 disposed inside the grinding head 23. Embedding the vibration motor 26 inside the grinding head 23 achieves structural integration, eliminating the need for an external excitation mechanism, reducing the overall height of the equipment, and making it easier to arrange in narrow workstations.

[0025] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
