Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of surface treatment equipment for parts, and in particular to a polishing and grinding device. Background Technology
[0002] Precision parts often require high surface finish. For example, the surface of an oxygen vapor mat needs to be polished using polishing equipment to meet process requirements. Currently, commonly used surface polishing equipment typically employs polishing wheels to continuously polish and grind the surface of the part until the required surface roughness is achieved. However, with increasing years of use, the polishing wheels in existing equipment experience varying degrees of wear. Consequently, the diameter of the polishing wheel gradually decreases. Furthermore, since the surface of the part is inherently uneven, the gap between the polishing wheel and the part cannot be dynamically adjusted after the polishing wheel wears down. This results in uneven polishing and inconsistent depth of polishing, negatively impacting the overall polishing effect. Utility Model Content
[0003] This invention addresses the technical problem in the prior art where the gap between the polishing wheel and the part cannot be dynamically adjusted after the polishing wheel wears down, resulting in uneven polishing and varying degrees of polishing. It provides a polishing and grinding device.

The power device is fixed on the mounting support, and the movable end of the power device is connected to the intermediate walking mechanism. The power device is used to drive the intermediate walking mechanism to move longitudinally in a straight line.

[0024] In a preferred embodiment provided by this utility model, see [link to previous section]. Figures 1-3 The intermediate traveling mechanism includes: an intermediate movable plate 17, a first limiting block 10, and a second limiting block 27. The intermediate movable plate 17 is longitudinally arranged. One side of the intermediate movable plate 17 is connected to the mounting support 7 via a first sliding mechanism, allowing the intermediate movable plate 17 to move longitudinally relative to the mounting support 7 via the first sliding mechanism. The other side of the intermediate movable plate 17 is connected to a floating component via a second sliding mechanism, allowing the floating component to move longitudinally relative to the intermediate movable plate 17 via the second sliding mechanism.

Limiting mechanisms are provided on both the first and second sliding mechanisms to prevent the first slide rail 2 from disengaging from the first slider 3, and to prevent the second slide rail 16 from disengaging from the second slider 15.
[0026] See Figures 1-3The working process of the polishing and grinding device provided in this embodiment is as follows: the part is fixed below the polishing and grinding device, the movable end of the power device 1 is controlled to move downward, and the power device 1 drives the intermediate walking mechanism and the floating component to move downward until the lower edge of the polishing wheel 11 contacts the surface of the part. As the diameter of the polishing wheel 11 gradually decreases during use or the surface of the part becomes uneven, the floating component provides a downward pulling force under its own gravity, so that the polishing wheel 11 always reliably contacts the surface of the part. The motor 26 drives the polishing wheel 11 to rotate, polishing the surface of the part. When the sensing contact 5 moves to the position of the first sensor 4, the first sensor 4 sends a first sensing signal to the controller, and the controller sends a control signal to the power device 1, controlling the movable end of the power device 1 to move upward; when the sensing contact 5 moves to the position of the second sensor 6, the second sensor 6 sends a second sensing signal to the controller, and the controller sends a control signal to the power device 1, controlling the movable end of the power device 1 to move downward, so that the force on the polishing wheel 11 remains stable, further improving the polishing and grinding quality of the part.
[0027] See Figures 1-3 The polishing and grinding device provided in this embodiment of the present invention has the following beneficial effects: The polishing and grinding device provided in this embodiment of the utility model has a mounting support 7 fixed on a three-axis motion mechanism 28; an intermediate traveling mechanism is connected to the mounting support 7 via a first sliding mechanism; a power device 1 is fixed on the mounting support 7, and the movable end of the power device 1 is connected to the intermediate traveling mechanism, which drives the intermediate traveling mechanism to move longitudinally in a straight line; a floating component is longitudinally connected to the intermediate traveling mechanism via a second sliding mechanism, and the floating component can move longitudinally in a straight line along the second sliding mechanism; a polishing wheel 11 is rotatably mounted on the lower end of the floating component, and a motor 26 is connected to the polishing wheel 11 via a belt. In this polishing and grinding device, the polishing wheel 11 is set on the floating component. During the contact process with the part, the polishing wheel 11 can dynamically adjust the gap and pressure with the part, so that the polishing wheel 11 can continuously and reliably contact the surface of the part, solving the technical problem of poor polishing and grinding effect caused by the gradual reduction of the diameter of the polishing wheel 11 and the unevenness of the part surface during use.
