Description
Technical Field
[0001] This utility model relates to a grinding equipment for milling cutter grinding, specifically a milling cutter grinding machine. Background Technology
[0002] After a period of use, milling cutters need to have their cutting edges and outer diameter ground. Existing milling cutter grinding machines can only grind the cutting edges, while the grinding of the outer diameter must be done manually on a separate grinding machine, resulting in low grinding accuracy and low grinding efficiency. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual Z-axis milling machine that can realize the comprehensive automatic machining of the milling cutter cutting edge and the outer circle of the milling cutter through the setting of two power grinding wheels with dual Z-axis movement, thereby improving work efficiency.
[0004] This utility model is implemented through the following technical solution:
[0005] A dual Z-axis milling machine includes a milling cutter chuck rotatably mounted on a worktable slide. The rotation of the milling cutter chuck is driven by a milling cutter chuck motor. The worktable slide is driven by a transverse slide motor to move in the X-axis direction and by a longitudinal slide motor to move in the Y-axis direction. The milling cutter chuck is characterized by having a milling cutter cutting edge grinding wheel and a milling cutter external cylindrical grinding wheel corresponding to the milling cutter chuck. The milling cutter cutting edge grinding wheel is rotatably mounted on a first vertical slide, and its rotation is driven by a cutting edge grinding wheel motor. The first vertical slide is driven by a first slide motor to move along the Z-axis direction. The milling cutter external cylindrical grinding wheel is rotatably mounted on a second vertical slide, and its rotation is driven by an external cylindrical grinding wheel motor. The second vertical slide is driven by a second slide motor to move along the Z-axis direction.
[0006] The first vertical slide has a tool setting device installed on the side of the milling cutter's grinding wheel. The tool setting device has a tool setting probe, and the bottom surface of the tool setting probe is a bevel to form a single-sided sharp angle.
[0007] By adopting the above technical solution, this utility model, through the setting of two power grinding wheels with dual Z-axis motion, and the milling cutter clamping moving with the X-axis and Y-axis directions of the worktable slide, and with the assistance of a purchased tool setting device, can easily realize the comprehensive automatic machining of the milling cutter cutting edge and the outer circle of the milling cutter, thereby improving grinding accuracy and greatly improving work efficiency.

[0015] As shown in the figure, the dual Z-axis milling machine of this utility model includes a milling cutter chuck 10 rotatably mounted on a worktable slide 12. The rotation of the milling cutter chuck 10 is driven by a milling cutter chuck motor 11. The worktable slide 12 moves in both the X and Y axes on the worktable 14. The X-axis movement is driven by a transverse slide motor 13, and the Y-axis movement is driven by a longitudinal slide motor. Corresponding to the milling cutter chuck 10 are milling cutter cutting edge grinding wheels 1 and milling cutter external cylindrical grinding wheels 9. The milling cutter cutting edge grinding wheels 1 are rotatably mounted on a first vertical slide 2. The rotation of the milling cutter cutting edge grinding wheels 1 is driven by the milling cutter cutting edge grinding wheels 9. Driven by the grinding wheel motor 3, the first vertical slide 2 is driven by the first slide motor 4 to move along the Z-axis. The milling cutter outer cylindrical grinding wheel 9 is rotatably mounted on the second vertical slide 8. The rotation of the milling cutter outer cylindrical grinding wheel 9 is driven by the outer cylindrical grinding wheel motor 6. The second vertical slide 8 is driven by the second slide motor 5 to move along the Z-axis. A tool setting device 7 is set on the side of the milling cutter cutting edge grinding wheel 1 on the first vertical slide 2. The externally purchased model of the tool setting device 7 can be an MTL25Led-PLus wired probe. The tool setting device 7 has a tool setting probe 15. The bottom surface of the tool setting probe 15 is a bevel to form a single-sided sharp angle 151.
[0016] The invention is used as follows: The milling cutter 100 to be ground is quickly clamped and fixed by the milling cutter chuck. The worktable slide moves in the X-axis direction towards the milling wheel of the milling cutter cutting edge (at this time, the tool setting device is at the lower limit). When the center of the end face of the milling cutter cutting edge contacts the tool setting probe, the position of the milling cutter is determined and transmitted to the equipment control system. Then, the worktable slide moves back 2mm, and at the same time, the first vertical slide moves slightly upward in the Z-axis direction, causing the tool setting device to move upward as well, so that the tool setting probe leaves the contact with the end face of the milling cutter cutting edge. Then, the worktable slide moves forward 2.5mm in the X-axis direction, so that the center of the end face of the milling cutter head is located below the tool setting probe. Figure 4 As shown), at this time, the milling cutter chuck rotates at a small angle, and the convex edges on both sides of the center of the milling cutter end face will touch the single-sided sharp corner of the tool setting probe (as shown). Figure 5 As shown in the diagram, the angle position of the milling cutter is determined and transmitted to the equipment control system. After the above actions are completed, the first vertical slide moves in the Z-axis direction to bring the milling cutter's grinding wheel to the milling cutter's grinding position. The worktable slide drives the milling cutter chuck and the milling cutter on it to the milling cutter's grinding position as well. The milling cutter's grinding wheel rotates, cooperating with the controlled rotation of the milling cutter chuck and the X-axis feed of the worktable slide to complete the automatic grinding of the milling cutter's edge. After the automatic grinding of the milling cutter's edge is completed, the tool setter readjusts the angle position of the milling cutter. Then, the worktable slide drives the milling cutter chuck and the milling cutter on it to the milling cutter's outer diameter grinding position. The second vertical slide moves in the Z-axis direction to bring the milling cutter's outer diameter grinding wheel to the milling cutter's outer diameter grinding position as well. The milling cutter's outer diameter grinding wheel rotates, cooperating with the controlled rotation of the milling cutter chuck and the X-axis feed of the worktable slide to complete the automatic grinding of the milling cutter's outer diameter. Throughout the entire process described above, this invention utilizes two powered grinding wheels with dual Z-axis motion, coupled with the milling cutter clamping and movement along the X and Y axes of the worktable slide. With the assistance of a tool setting device, it can easily achieve comprehensive automatic machining of the milling cutter's cutting edge and outer diameter, thereby improving grinding accuracy and significantly increasing work efficiency.
