Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a milling cutter which is easy to replace. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the workpiece's excess in sequence and intermittently. Milling cutters are mainly used to process planes, steps, grooves, formed surfaces and cut off workpieces on milling machines, and play an important role in the processing of mechanical equipment.

[0003] At present, the Chinese utility model patent application with publication number CN218362318U proposes a milling cutter, including a cutter body, the cutter body including a base layer, and a high-strength layer is provided on the outer side of the base layer. At the same time, the high-strength layer includes a molybdenum alloy layer and a nickel alloy layer. The outer side of the high-strength layer is provided with an anti-rust layer, and the anti-rust layer includes an iron red phenolic rust-proof coating and an acrylic anti-rust coating. The utility model is provided with an anti-rust layer, which can provide two layers of anti-rust protection for the outer side of the base layer (the acrylic anti-rust coating serves as a first layer of anti-rust protection, and the iron red phenolic rust-proof coating serves as a second layer of anti-rust protection after the acrylic anti-rust coating is damaged). The high-strength layer is provided, which can provide two layers of enhanced protection for the outer side of the base layer (the nickel alloy layer serves as a first layer of enhanced protection, and the molybdenum alloy layer serves as a second layer of enhanced protection after the nickel alloy layer is damaged). Through the combination of the above structures, the service life of the entire CNC milling cutter is effectively improved.

[0004] However, the existing machine tool milling cutter head has certain disadvantages when in use. In order to ensure the stable connection and working strength of the milling cutter during operation, the installation structure is designed with multiple fixed structures. The steps of installing and replacing the milling cutter are cumbersome and complicated, which reduces the work efficiency of replacing the milling cutter. Utility Model Content

DETAILED DESCRIPTION

[0023] The following combination Figures 1-4 The utility model is described in further detail.

[0024] This embodiment discloses a milling cutter that is easy to replace: Figures 1-4 A milling cutter that is easy to replace includes a mounting base 10, a milling cutter body 20, a mounting assembly 30 and a control assembly 40. The milling cutter body 20 is detachably mounted on the mounting base 10 through the mounting assembly 30;

[0025] The mounting assembly 30 includes a turntable 31, a connecting seat 32, a plurality of round blocks 33 and a plurality of insertion rods 34. The mounting seat 10 is provided with a mounting groove 11. The inner wall of the mounting groove 11 is provided with a plurality of sliding grooves 12 for slidingly installing the insertion rods 34. The turntable 31 is rotatably arranged in the mounting seat 10. The turntable 31 is provided with a plurality of arc-shaped grooves 311 for slidingly installing the round blocks 33. The insertion rods 34 are connected to the round blocks 33. The connecting seat 32 is provided on the milling cutter body 20 through the connecting plate 21. The connecting seat 32 is provided with a plurality of slots 321.

[0026] The control assembly 40 is disposed on the mounting base 10 and is used to control the rotation of the turntable 31 .

[0027] When the tool is to be installed, the connecting seat 32 is placed in the installation groove 11 and the rod 34 is aligned with the slot 321. The control assembly 40 drives the turntable 31 to rotate, and the rod 34 and the round block 33 respectively perform centrifugal movement under the constraints of the slide groove 12 and the arc groove 311, and the rod 34 is inserted into the slot 321 to complete the installation. When the tool is to be removed, the turntable 31 is driven by the control assembly 40 to rotate in the opposite direction, and the rod 34 and the round block 33 respectively perform centrifugal movement under the constraints of the slide groove 12 and the arc groove 311, and the rod 34 falls off the slot 321. At this time, the connecting plate 21 is moved away from the mounting seat 10, and the milling cutter can be taken out. The arrangement of the turntable 31, the connecting seat 32, the multiple round blocks 33 and the multiple rods 34 allows the staff to disassemble and assemble the milling cutter by simply rotating the turntable 31 and moving the connecting plate 21. The operation is simple and convenient, which improves work efficiency.

[0028] Reference Figure 1 The surface of the milling cutter body 20 is provided with a coating.

[0029] The surface coating of the milling cutter body 20 can increase the hardness of the tool and enhance its wear resistance, thereby reducing the wear of the milling cutter body 20 during use and extending the service life of the milling cutter body 20; and, the surface coating of the milling cutter body 20 can effectively reduce the friction coefficient between the tool and the workpiece, thereby reducing the cutting force and the heat caused by friction and improving cutting efficiency.

[0030] Reference Figures 2 to 3 , a plurality of limiting rods 22 are provided on the connecting plate 21 , and a plurality of limiting grooves 13 are provided on the mounting seat 10 .

[0031] When installing the milling cutter, place the connecting seat 32 in the installation groove 11, and place the limiting rod 22 in the limiting groove 13, and continue to move the connecting plate 21 in the direction close to the mounting seat 10 until the connecting plate 21 contacts the bottom wall of the mounting seat 10. At this time, the insertion rod 34 is aligned with the slot 321, and the turntable 31 is driven to rotate by the control component 40. The insertion rod 34 and the round block 33 are respectively constrained by the slide groove 12 and the arc groove 311, and the insertion rod 34 is inserted into the slot 321 to complete the installation. Therefore, the setting of the limiting rod 22 and the limiting groove 13 enables the staff to quickly and conveniently make the insertion rod 34 correspond to the slot 321, and the insertion rod 34 can be inserted into the slot 321 by rotating the turntable 31. The operation is simple and convenient, which improves work efficiency.

[0032] Reference Figures 2 to 4 The plurality of inserting rods 34 are distributed in a circular array around the mounting groove 11 .

[0033] The arrangement of the four insertion rods 34 allows the insertion rods 34 to limit the periphery of the milling cutter body 20, thereby enhancing the limiting effect of the insertion rods 34 and reducing the probability of the milling cutter body 20 becoming loose during use.

[0034] Reference Figure 1-Figure 2 The control component 40 includes a slide rod 41, which is arranged on the side wall of the turntable 31. The mounting seat 10 is used to slide and install the slide rod 41 by opening a groove 14. A thread is provided on the side wall of the end of the slide rod 41 away from the turntable 31, and the slide rod 41 is connected to the knob 42 by rotating the thread.

[0035] When the turntable 31 needs to be rotated, the knob 42 is sliding, and the slide bar 41 is reversed, thereby driving the turntable 31 to rotate. Therefore, the setting of the slide bar 41 and the knob 42 makes it convenient for the user to control the rotation of the turntable 31; the groove 14 is used to reduce the probability of the slide bar 41 shaking during use.

[0036] Reference Figure 2 , the knob 42 abuts against the side wall of the mounting seat 10 .

[0037] After the milling cutter is installed, in order to reduce the probability of the milling cutter body 20 loosening during use, the knob 42 is turned to make the knob 42 abut against the side wall of the mounting seat 10, and the turntable 31 is difficult to rotate, so that the insertion rod 34 and the round block 33 are difficult to shake under the limitation of the slide groove 12 and the arc groove 311, thereby improving the fixing effect of the mounting assembly 30.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
