It includes a movable seat and a milling cutter, wherein the movable seat is equipped with a tool seat, and the tool seat is movably equipped with a movable seat, and the milling cutter is installed on the movable seat; it also includes an offset alarm device, wherein the offset alarm device is installed on the tool seat, and the offset alarm device is located on one side of the milling cutter. The offset alarm device is used to perform an offset alarm for the position of the milling cutter. Through the setting of the offset alarm device, when the milling cutter is skewed, the extrusion frame is squeezed, thereby driving the driving frame to move. When the driving frame moves, it can squeeze the switch so that the sound alarm can turn on the alarm, so that the alarm can be issued in time to remind the staff to deal with it in time, thereby avoiding damage to the workpiece or the tool, and can ensure the processing quality while saving the use of the milling cutter.

[0003] This device can be used in the production of machine tool tools. Through the offset alarm device, an alarm is issued when the milling cutter is skewed. However, the device has a complex structure and is easily damaged during the separation process of the movable seat, which is inconvenient for subsequent maintenance and tool replacement.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-6 A machine tool tool for milling a workpiece includes a tapered shank 1, the lower end surface of the tapered shank 1 is fixedly connected to a connecting seat 2 by means of bolts, the lower end surface of the connecting seat 2 is movably abutted against a tool seat 3, a tool groove 306 is provided inside the tool seat 3, a milling cutter 4 is inserted and fixed inside the tool groove 306, and the tool seat 3 and the connecting seat 2 are fixedly connected by means of a connecting assembly;

[0025] The connecting assembly includes multiple groups of connecting frames 5, and multiple groups of locking grooves 302 are provided on the outer end faces of the tool seat 3 and the connecting seat 2. A fixing groove 303 is provided inside the locking groove 302, and the connecting frame 5 is inserted into the fixing groove 303 from the locking groove 302. A disconnecting notch 501 is provided in the middle of the connecting frame 5, and the connecting seat 2 and the tool seat 3 are fixed by multiple groups of connecting frames 5. When the milling cutter 4 collides and deviates, the connecting frame 5 can be broken at the disconnecting notch 501, thereby separating the connecting seat 2 and the tool seat 3, which can reduce the risk caused by the collision and avoid damage to the tool. The device sets the connecting frame 5 as a consumable, which reduces the risk caused by the machine continuing to mill when the milling cutter 4 deviates, and has good safety. The separation of the connecting frame 2 and the tool seat 3 will not destroy the overall structure of the tool, and the structure is simple and easy to install and replace later. A rubber ring can be set on the outer end face of the connecting frame 5 to prevent the connecting frame 5 from detaching under high-speed rotation without affecting the breakage of the connecting frame 5.

[0026] The tool groove 306 is internally slidably connected to a movable plate 7, and an elastic member 8 is provided inside the tool groove 306 to abut against the movable plate 7 to move outward. The milling cutter 4 movably abuts against the movable plate 7 to move inward, and the position of the movable plate 7 is fixed by the elastic member 8. The movable plate 7 is driven by the insertion of the milling cutter 4, thereby displaying the insertion depth of the milling cutter 4.

[0027] A scale groove 304 is provided on the outer end face of the tool seat 3, and a scale bar 701 extending into the interior of the scale groove 304 is fixedly connected to the outer end face of the movable plate 7. A plurality of groups of scale lines 305 cooperating with the scale bar 701 are provided inside the scale groove 304. By setting the scale groove 304 and the scale lines 305, when the milling cutter 4 is inserted into the tool groove 306, it abuts against the movable plate 7 and the scale bar 701 and moves, so that the distance the milling cutter 4 is inserted into the tool groove 306 can be clearly checked, which facilitates better installation of the milling cutter 4.

[0028] A transparent sealing shell 6 is inserted and fixed inside the scale groove 304. The sealing shell 6 can prevent debris generated by the milling pin from entering the tool groove 306 through the scale groove 304. At the same time, the transparent material makes it easy to check the scale changes.

[0029] The upper end face of the connecting seat 2 is provided with a plug-in slot 201, and the lower end face of the tapered handle 1 is fixedly connected with a plug-in block 101, which is movably engaged with the inside of the plug-in slot 201. The cooperation between the plug-in block 101 and the plug-in slot 201 prevents the tapered handle 1 from being offset during installation.

[0030] The lower end face of the connecting seat 2 is provided with a positioning groove 202, and the upper end face of the tool seat 3 is provided with a positioning ring 301 that cooperates with the positioning groove 202. The cooperation between the positioning groove 202 and the positioning ring 301 can prevent deviation during installation, and the arc-shaped positioning ring 301 can avoid damage during separation.

[0031] The outer end surface of the connecting frame 5 is fixedly connected with multiple groups of plug-in blocks 502 , and the plug-in blocks 502 are provided to facilitate the removal of a broken connecting frame 5 .

[0032] When the tool is in working order, the tool holder 3 is fixed with the taper handle 1 and the connecting seat 2 by bolts, and the connecting seat 2 and the tool holder 3 are fixed by multiple sets of connecting frames 5. A rubber ring can be set on the outer end surface of the connecting frame 5 to prevent the connecting frame 5 from detaching under high-speed rotation, without affecting the breakage of the connecting frame 5. At this time, the milling cutter 4 is inserted into the tool groove 306, and the milling cutter 4 abuts the movable plate 7 and the scale bar 701 to move. The depth of the milling cutter 4 inserted into the tool groove 306 can be checked, which is convenient for better installation of the milling cutter 4. Finally, the taper handle 1 is installed in the tool position of the machine tool. When the milling cutter 4 is offset by collision, the connecting frame 5 can be broken by the disconnecting notch 501, thereby separating the connecting frame 2 and the tool holder 3, which can reduce the risk of collision and avoid damage to the tool. The device sets the connecting frame 5 as a consumable, which reduces the risk of continuous milling of the machine when the milling cutter 4 is offset, and has good safety. The separation of the connecting frame 2 and the tool holder 3 will not damage the overall structure of the tool, and it has a simple structure and is easy to install and replace later.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
