Technical Field
[0001] The utility model belongs to the technical field of grinding machine equipment, in particular to a precision vertical grinding machine. Background Art
[0002] A vertical grinder is a machine tool consisting of a worktable, power and transmission devices, a guide base, guide rails, a grinding tool, and a polishing wheel. However, existing vertical grinders have the following shortcomings: 1. It is difficult to rotate the material placed on the worktable to move it to the appropriate grinding position during use, resulting in limited flexibility. They can only process the sides of workpieces with regular surfaces, such as trihedrons, tetrahedrons, hexahedrons, and octahedrons, but not workpieces with convex sides. 2. Existing vertical grinders have low machining accuracy. Therefore, improvements to the structure of existing vertical grinders are needed. Utility Model Content

[0004] The utility model is realized through the following technical solutions:
[0005] The cam is provided with a lifting frame, and the lifting frame is driven by the Z-axis screw nut at the bottom to slide up and down along the Z-axis track. The lifting frame is provided with a grinding head and a motor to drive the grinding head to rotate, and the axial direction of the grinding head shaft is vertical.
[0006] Furthermore, the material rotating rack is driven by a driving device to rotate within a range of 360 degrees in a horizontal plane.
[0007] Furthermore, the X-axis lead screw, the Y-axis lead screw and the Z-axis lead screw are all high-precision lead screws.
[0008] Furthermore, the material rack base and the grinding head rack base are distributed in a T shape.
[0009] Furthermore, the X-direction track, the Y-direction track and the Z-direction track are all double linear tracks.
[0010] The beneficial effects of the present invention are as follows: 1. The precision vertical grinder of the present invention is provided with a material rotating frame, and the material can be rotated while being fed and processed, so that it can process workpieces with regular side surfaces such as trihedrons, tetrahedrons, hexahedrons, octahedrons, etc., and can also process workpieces with convex side surfaces and workpieces with large rounded concave side surfaces, thereby improving the flexibility of the grinding machine; 2.

[0014] The present invention will be further described below with reference to specific examples and accompanying drawings.
[0015] like Figure 1 、 Figure 2As shown, a precision vertical grinder includes a material rack base 1 and a grinding head rack base 6, which are fixed adjacent to each other in the horizontal direction; the material rack base 1 and the grinding head rack base 6 are arranged in a T-shape. A horizontal X-track 2 and an X-screw 4 are provided on the material rack base 1. A material rack slide 3 is provided on the X-track 2. The material rack slide 3 is driven by the X-screw 4 via a screw nut at its bottom to slide horizontally along the X-track 2. A material turret 5 is provided on the material rack slide 3. Material 14 is placed on the material turret 5 and is driven by a drive device to rotate 360 degrees within the horizontal plane along with the material turret 5. A horizontal Y-direction track 7 is provided on the base 6 of the grinding head frame, and a vertical frame 8 and a Y-direction screw 9 are provided on the Y-direction track 7. The vertical frame 8 is driven by the Y-direction screw 9 through the screw nut at the bottom to slide horizontally along the Y-direction track 7; the vertical frame 8 is provided with a Z-direction track 10 and a Z-direction screw 12 on the side close to the material rotating frame 5, and a lifting frame 11 is provided on the Z-direction track 10. The lifting frame 11 is driven by the Z-direction screw 12 through the screw nut at the bottom to slide up and down along the Z-direction track 10, and a grinding head 13 and a motor for driving the grinding head 13 to rotate are provided on the lifting frame 11, and the axial direction of the rotating shaft of the grinding head 13 is in the vertical direction.
[0016] The X-direction screw rod 4 , the Y-direction screw rod 9 and the Z-direction screw rod 12 are all high-precision screw rods.
[0017] The X-direction track 2 , the Y-direction track 7 and the Z-direction track 10 are all double linear tracks.
[0018] When the precision vertical grinder of the present invention is working, the material 14 is mounted on the material rotating frame 5 ( Figure 1In the figure, the hexahedral material 14 is on the material rotating frame 5, while the material 14 with convex side surfaces is in a suspended state. During actual processing, the material 14 must be installed on the material rotating frame 5. The material 14 with convex side surfaces is shown here to illustrate that the precision vertical grinder of the present invention can conveniently process such materials). The bottom of the material rotating frame 5 is installed on the material rack slide 3, and the material rack slide 3 is driven by the X-direction screw 4 through the lower screw nut to slide horizontally along the X-direction track 2 to complete the feeding in the X-axis direction. While the material rotating frame 5 is set, the material 14 is fed and processed in the X-axis direction. The material 14 can also be driven by the driving device to rotate 360 degrees in the horizontal plane with the material rotating frame 5. In this way, it can process workpieces with regular side surfaces such as trihedrons, tetrahedrons, hexahedrons, octahedrons, etc., and can also process workpieces with convex side surfaces and workpieces with large rounded concave side surfaces, thereby improving the flexibility of the grinding machine processing. The grinding head 13 and the motor that drives the grinding head 13 to rotate are installed on the lifting frame 11, and the lifting frame 11 is installed on the vertical frame 8. The vertical frame 8 is driven by the Y-direction screw 9 through the screw nut at the bottom to slide horizontally along the Y-direction track 7; and the lifting frame 11 is driven by the Z-direction screw 12 through the screw nut at the bottom to slide up and down along the Z-direction track 10, so that the grinding head 13 can not only move toward or away from the material 14 from the Y-axis direction, but also move toward or away from the material 14 from the Z-axis direction for processing, and high-precision screws and double linear tracks are arranged in the X, Y, and Z axes to improve the processing accuracy of the grinder.
