Description

Technical Field

[0001] The utility model relates to the technical field of machine tool tool correction, in particular to a horizontal digital display tool setting instrument for a numerically controlled hole-type lathe. Background Art

[0002] In steel-rolling production enterprises, the processing of roll hole profiles is a very important task. Its processing efficiency affects the normal production, and the processing quality directly affects the quality of the final product, especially for the processing of special-shaped holes. When the roll frame of the CNC hole profile lathe is working, three blades need to be evenly installed on the cutter body, and then the positions of the three blades on the cutter body are adjusted so that the movement trajectories of the three blades are on the same arc, ensuring the same rotation center deviation of the three blades.

[0003] The structure of the CNC hole-type lathe is complex. Since the CNC hole-type lathe is equipped with a reversing clamping mechanism, it is not convenient to align the tool directly on the lathe. The cutter body and the blade need to be removed from the CNC hole-type lathe for offline tool alignment. After the position of the blade on the cutter body is aligned offline, the cutter body is installed on the CNC hole-type lathe for operation. There are many ways to align the blade on the existing cutter body, such as: fixing the digital height gauge at a certain position, and then manually rotating the cutter body to achieve tool alignment, placing the cutter body at a certain position, and measuring the distance between the two blades with a vernier caliper, and fixing the cutter body and adjusting the position of the digital height gauge to achieve tool alignment, etc.; these three tool alignment methods all have the problem of inaccurate tool alignment accuracy, which is easy to cause large errors. Utility Model Content

A rotating shaft is rotatably arranged on a fixed longitudinal support plate, and a tool holder body is fixed at one end of the rotating shaft so that the axis of the tool holder body and the axis of the rotating shaft are colinear. The motion trajectory of the blade during operation is simulated by rotating the rotating shaft, and the three blades on the tool holder body are measured and corrected at the same time by a digital display height gauge, thereby improving the tool setting accuracy.

Figure 1 and Figure 3 As shown, a bearing seat 4 is embedded in the middle of the two longitudinal support plates 2, a bearing 5 is embedded in the bearing seat 4, a rotating shaft 3 is rotatably arranged on the bearing 5, a sealing cover 17 is fixedly arranged on the bearing seat 4 and at one end away from the clamping cutter body 11, a clamping member 6 for limiting the bearing 5 is arranged on the outer side of the bearing seat 4 to prevent the bearing 5 and the rotating shaft 3 from being displaced laterally when the rotating shaft 3 rotates, and a driving component for driving the rotating shaft 3 to rotate is arranged on the longitudinal support plate 2. Further, in combination with Figure 1 , Figure 2 and Figure 3 As shown, the driving assembly includes a transverse support plate 7, which is symmetrically arranged between the two longitudinal support plates 2. A worm 8 is rotatably arranged between the two transverse support plates 7. It should be noted that the worm 8 does not move left and right when rotating. A handle 9 is arranged at one end of the worm 8. A worm wheel 10 cooperating with the worm 8 is sleeved in the middle of the rotating shaft 3. Preferably, the rotation speed of the rotating shaft 3 can be adjusted by the cooperation of the worm wheel 10 and the worm 8, and the value at the local position of the blade 14 can be more accurately measured by slowly rotating the rotating shaft 3, which provides convenience for improving the adjustment accuracy of the blade 14 on the clamping body 11.

[0021] Specifically in this embodiment, combined with Figure 1 or Figure 2As shown, a cutter body 11 is provided at one end of the rotating shaft 3. Furthermore, a positioning hole 12 is opened at the axis of the rotating shaft 3 on one side close to the cutter body 11, and a positioning shaft 13 cooperating with the positioning hole 12 is provided at the axis of the cutter body 11. Preferably, the positioning shaft 13 cooperates with the positioning hole 12 to make the axis of the cutter body 11 and the axis of the rotating shaft 3 colinear. The cutter body 11 is driven to rotate by rotating the rotating shaft 3 to simulate the movement trajectory of the blade 14 during the working process, and the three blades 14 on the cutter body 11 are measured and corrected at the same time by the digital height gauge 15 on the other side of the base 1 to improve the tool setting accuracy.

A marking claw 16 for measuring the blade 14 is provided at one end of the digital height gauge 15 close to the cutter body 11.

[0022] Working principle:

[0023] When tool alignment is required, the staff first removes the connecting bolts between the tool holder 11 and the lathe spindle, and removes the tool holder 11 and the blade 14 on the tool holder 11 from the spindle of the CNC hole type lathe, and then connects the tool holder 11 to the end of the rotating shaft 3 through the connecting bolts, and then adjusts the height of the digital height gauge 15, and adjusts the marking claw 16 at the end of the digital height gauge 15 to an ideal size, and then rotates the worm 8 through the handle 9 to realize the rotation of the rotating shaft 3. When the rotating shaft 3 rotates, it drives the tool holder 11 to rotate. When the tool holder 11 rotates, the position of the blade 14 on the tool holder 11 can be adjusted with the marking claw 16 as the reference point. When the three blades 14 are adjusted to coincide with the point pointed by the marking claw 16, the tool alignment function is completed, and then the staff holds the tool holder 11 and removes the connecting bolts between the tool holder 11 and the rotating shaft 3, and finally connects it to the spindle of the CNC hole type lathe through the connecting bolts.
