Description

Technical Field

[0001] This utility model relates to the field of drill bit processing technology, specifically to a cutting tool grinding device. Background Art

[0002] A grinding device is a mechanism used for grinding the tip edge of a drill bit. It is fixed on a grinding station on the periphery of the tool processing equipment. The clamping mechanism of the rotary table at the center of the machine is located in front of the grinding device. The rough grinding unit and the fine grinding unit on the grinding device move back and forth synchronously along the X and Y axes, and rotate back and forth along the C axis (the C axis is the direction of rotation around the Z axis). In conjunction with the clamping mechanism, the drill bit is driven to rotate around the B axis (the B axis is the direction of rotation around the Y axis), thereby realizing the rough grinding and fine grinding of the drill bit tip edge. However, because the feed depth of the rough grinding unit is greater than that of the fine grinding unit during the fine grinding process, and the rough grinding unit of the traditional grinding device cannot move back and forth along its axis independently, the rough grinding efficiency of the drill bit tip edge is low and the grinding effect is relatively rough. At the same time, the subsequent fine grinding process requires more time, thus reducing the overall grinding efficiency and accuracy of the tip edge. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] See Figure 1-6As shown in the figure, as an embodiment of this utility model, a grinding device is provided. The left-right direction of the grinding device is the X-axis direction, the front-back direction is the Y-axis direction, the up-down direction is the Z-axis direction, the rotation direction around the X-axis direction is the A-axis direction, the rotation direction around the Y-axis direction is the B-axis direction, and the rotation direction around the Z-axis direction is the C-axis direction. The grinding device includes a fixed base that can move back and forth along the X-axis and Y-axis directions and rotate back and forth along the C-axis direction. A rough grinding mechanism and a fine grinding mechanism are installed on the fixed base. Specifically, it also includes a base 1, a Y-axis adjusting seat 2, and an X-axis adjusting seat 3. The Y-axis adjusting seat 2 is adjustable along the C-axis direction on the base 1. The X-axis adjusting seat 3 is installed on the Y-axis adjusting seat 2, and the fixed base is installed on the X-axis adjusting seat 3. The Y-axis adjusting seat 2 is used to drive the X-axis adjusting seat 3 to move back and forth along the Y-axis direction, and the X-axis adjusting seat 3 is used to drive the fixed base to move back and forth along the X-axis direction. That is, the fixed base can move back and forth along the X-axis and Y-axis directions through the cooperation of the base 1, the Y-axis adjusting seat 2, and the X-axis adjusting seat 3. The coarse grinding mechanism rotates back and forth along the C-axis, thereby driving the coarse grinding mechanism and the fine grinding mechanism to move back and forth along the X and Y axes and rotate back and forth along the C-axis synchronously. The coarse grinding mechanism includes an axial drive 6, a first drive 7, and a coarse grinding unit 8 that is driven and connected to the axial drive 6 and the first drive 7 respectively. The fine grinding mechanism includes a second drive 9 and a fine grinding unit 10 that is driven and connected to the second drive 9. The second drive 9 drives the fine grinding unit 10 to rotate around its axis, the first drive 7 drives the coarse grinding unit 8 to rotate around its axis, and the axial drive 6 drives the coarse grinding unit 8 to move back and forth along its axis. This arrangement allows the coarse grinding unit 8 to move forward and backward independently along its axis, resulting in a greater feed depth of the coarse grinding unit 8. This allows for better coarse grinding of the drill bit's tip, improving coarse grinding efficiency and grinding effect. Consequently, the subsequent fine grinding unit 10 performs fine grinding in a shorter time with higher precision, thereby improving the overall grinding efficiency and precision of the drill bit's tip.

The second connecting piece 12 is fixedly connected to the first driving piece 7 and the coarse grinding unit 8. That is, the slider 65 is driven to slide back and forth by the lead screw 64, which in turn drives the connecting side plate 62 to slide back and forth, and finally drives the coarse grinding unit 8 to move back and forth along its axis. The fixed housing 61 is provided with a first through hole 66, and the first fixed seat 4 is provided with a first arc-shaped hole 43.
