[0037] The utility model is described in detail below in combination with the drawings.

[0038] As Figures 1 to 4 shown, the utility model relates to a split type quick grinding tool face workstation, including angle offset mechanism 1, lower slide Y2 axis driver 2, upper slide X2 axis driver 3, secondary tool face grinding cutting part 4, upper slide Z2 axis driver 5 and main tool face grinding cutting part 6,

[0039] Lower slide Y2 axis driver 2 is arranged in angle offset mechanism 1 and is used to drive upper slide X2 axis driver 3 to slide;

[0040] Upper slide X2 axis driver 3 drives secondary tool face grinding cutting part 4 and upper slide Z2 axis driver 5 to slide simultaneously;

[0041] Upper slide Z2 axis driver 5 drives main tool face grinding cutting part 6 to slide.

[0042] Through the cooperation of lower slide Y2 axis driver 2, upper slide X2 axis driver 3 and upper slide Z2 axis driver 5, secondary tool face grinding cutting part 4 and main tool face grinding cutting part 6 can simultaneously grind the drill tip portion of semi-finished bar stock, reduce processing time and improve processing efficiency.

[0043] Since the upper slide Z2 shaft driver 5 can independently drive the main flank grinding cutting part 6 to slide, the main flank grinding cutting part 6 can be driven by the upper slide Z2 shaft driver 5 to avoid the rotating conveying shaft, preventing the interference between the grinding flank workstation and the rotating conveying shaft.

[0044] In use, the lower slide Y2 shaft driver is responsible for sliding on the angle offset mechanism to adjust the distance between the secondary flank grinding cutting part 4 and the main flank grinding cutting part 6 and the semi-finished bar.

[0045] The upper slide X2 shaft driver is responsible for sliding on the lower slide, facilitating the secondary flank grinding cutting part 4 and the main flank grinding cutting part 6 to reciprocate along the axial direction of the upper slide X2 shaft driver to process the semi-finished bar.

[0046] The upper slide Z2 shaft driver is responsible for driving the main flank grinding cutting part 6 to move along its axial direction, making the part more flexible to approach or move away from the semi-finished bar. This design enables the secondary flank grinding cutting part 4 and the main flank grinding cutting part 6 to act on the semi-finished bar at the same time, significantly improving the processing efficiency and shortening the processing cycle.

[0047] In the case of needing to avoid the rotating conveying shaft, the lower slide Y2 shaft driver 2 will be started to drive the secondary flank grinding cutting part 4, the upper slide Z2 shaft driver, and the main flank grinding cutting part 6 to slide and retreat together. During this process, the upper slide Z2 shaft driver also independently drives the main flank grinding cutting part 6 to retreat. Such cooperative operation not only reduces the sliding stroke of the lower slide Y2 shaft driver, but also reduces the adjustment stroke required for approaching and processing the semi-finished bar again, thereby reducing the preparation time for positioning adjustment and improving the flexibility and efficiency of the overall processing process.

[0048] On the other hand, after the secondary flank grinding cutting part 4 is driven by the lower slide Y2 shaft driver 2 and the upper slide X2 shaft driver 3 to complete the zero coordinate positioning with the semi-finished bar, the main flank grinding cutting part 6 is driven by the upper slide Z2 shaft driver 5 to process the semi-finished bar using the zero coordinate of the secondary flank grinding cutting part 4 and the semi-finished bar, reducing the time-consuming of secondary positioning.

[0049] As shown in Figure 2 The angle offset mechanism 1 of the present embodiment includes a fixed reference plate 11 and a sliding plate 12. The fixed reference plate 11 is provided with a sliding limiting groove 13, and the sliding plate 12 is provided with a sliding fastener 14. The sliding plate 12 is fixed with the fixed reference plate 11 after adjusting the angle by sliding along the sliding limiting groove 13 through the sliding fastener 14.

[0050] The angle biasing mechanism 1 realizes the accurate adjustment of the angle of the components connected or mounted on the sliding plate 12 by adjusting the sliding of the sliding plate 12 on the fixed reference plate 11. The adaptability and flexibility of the device are improved, so that the device can be quickly and accurately adjusted according to different processing requirements or working environments.

[0051] The cooperation of the sliding fastener 14 and the sliding limiting groove 13 ensures the stability and reliability of the sliding plate 12 during the adjustment process. Once the sliding plate 12 reaches the required angle position, the sliding fastener 14 can firmly fix it on the fixed reference plate 11, preventing the angle from shifting due to vibration or external force.

[0052] The sliding fastener 14 is a bolt and nut, which fixes the sliding plate 12 on the fixed reference plate 11 when the sliding plate 12 reaches the required angle position.

This design not only simplifies the structure of the device and reduces the manufacturing cost, but also improves the reliability and maintainability of the device.

[0056] The Y2 shaft actuator 22 is arranged in the Y2 fixed shell 21 and is used to drive the Y2 lower sliding plate 23 to accurately slide in a predetermined direction. This design ensures that the Y2 lower sliding plate 23 can smoothly and accurately move to the required position, thereby improving the processing precision and positioning accuracy of the device.
