Description

Technical Field

[0001] This application relates to the field of milling equipment, and more particularly, to a milling cutter that is easy to assemble. Background Art

[0002] A milling cutter is a rotating tool with one or more cutting teeth used for milling. During operation, each cutting tooth intermittently cuts off the surplus of the workpiece in turn. Milling cutters are mainly used for machining planes, steps, grooves, formed surfaces, and cutting workpieces on milling machines, etc.

[0003] Publication No. CN 219924674 U discloses an assembled coated milling cutter. Through the set fixing component, the tool shank is inserted into the inside of the connecting head and extends through the connecting head to the inside of the connecting sleeve. The clamping groove of the magnetic head at the top of the tool shank is attracted to the magnetic card block at the top end of the inner wall of the connecting sleeve. The tool body is connected to the connecting sleeve. Rotate the screw, and the screw drives the clamping block to move and clamp on the outside of the tool shank. The tool body is fixedly connected to the connecting head and the connecting sleeve. The coating increases the hardness and oxidation temperature of the tool body and extends the service life. The assembled connection installation reduces the situation of the milling cutter breaking during use.

[0004] However, there are some defects in the above solution: In the above solution, for the fixation of the milling cutter, it is necessary to rotate and remove each nut and then rotate each screw to clamp and fix. The method of individual operation is difficult to effectively ensure concentricity, and the method of fixing one by one individually is time-consuming and the disassembly and assembly efficiency is low.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0032] Please refer to Figures 1-6 , the present application provides a milling cutter that is easy to assemble, including a connection component 100 and a fixing component 200.

[0033] Please refer to Figure 1 and 2 , the connection component 100 includes a connection sleeve 110 and a connection head 120, and the connection head 120 is arranged at the bottom end of the connection sleeve 110.

[0034] Please refer to Figure 1 , 2 , 3, 4, 5 and 6, the fixing component 200 includes a tool holder 210, a sliding rod 220, a clamping block 230, a rotating ring 240, a positioning ring 250 and a threaded collar 270. The connection head 120 is provided with a communication hole 121. The sliding rod 220 and the clamping block 230 are both slidably arranged in the communication hole 121. The rotating ring 240 is rotatably arranged at the bottom end of the connection head 120. The rotating ring 240 is provided with an arc-shaped hole 241. The sliding rod 220 slidably penetrates through the arc-shaped hole 241. The positioning ring 250 is slidably sleeved on the connection head 120, and the threaded collar 270 is threadedly sleeved on the connection head 120.

[0035] Among them, the clamping block 230 is fixedly connected to the sliding rod 220, and the end face of the clamping block 230 is arc-shaped. By providing the clamping block 230 with an arc-shaped end face, it can better fit the outer wall of the cylindrical milling cutter.

[0036] Specifically, the inner wall of the communication hole 121 is provided with a groove 122, and the clamping block 230 is slidably arranged in the groove 122. By providing the groove 122, it is used to accommodate and guide the clamping block 230.

[0037] In this embodiment, an extension rod 221 is fixedly connected to the bottom of the sliding rod 220, and the extension rod 221 slidably penetrates through the arc-shaped hole 241. By providing the extension rod 221 to slidably penetrate through the arc-shaped hole 241, when the rotating ring 240 is rotated, the arc-shaped hole 241 on the rotating ring 240 drives the extension rod 221 to move, and the extension rod 221 drives the sliding rod 220 to move, realizing the clamping and fixing function.

[0038] It should be noted that a T-shaped arc block 242 is arranged at the top of the rotating ring 240, and a chute 123 is opened at the bottom end of the connection head 120. The T-shaped arc block 242 is slidably arranged in the chute 123. By providing the T-shaped arc block 242 to slide in the chute 123, the rotating ring 240 is rotatably connected to the bottom of the connection head 120.

[0039] In a specific embodiment, racks 260 are provided on the outer sides of the rotating ring 240 and the connecting head 120. The positioning ring 250 is provided with tooth grooves 251, and the racks 260 and the tooth grooves 251 are engaged with each other. By providing the engagement between the racks 260 and the tooth grooves 251, the positioning ring 250 connects the rotating ring 240 and the connecting head 120 to achieve locking.

[0040] Specifically, an external thread 124 is provided on the outer side of the connecting head 120, and the threaded sleeve ring 270 is adapted to the external thread 124. By providing the external thread 124, it can be rotated and axially moved. The threaded sleeve ring 270 pushes the positioning ring 250 to keep connecting the rotating ring 240 and the connecting head 120.

[0041] In a specific embodiment, a cutter body 280 is integrally formed at the bottom of the tool handle 210 and is provided with a coating.

[0042] The working principle of the easily assembled milling cutter: During installation, the tool handle 210 is inserted into the connecting sleeve 110 through the connecting head 120. The rotating ring 240 is operated to rotate. The arc-shaped hole 241 on the rotating ring 240 drives the extension rod 221 to move. The extension rod 221 drives the sliding rod 220 to move. The sliding rod 220 drives the clamping block 230 to move, and multiple sliding rods 220 and clamping blocks 230 move synchronously to jointly clamp the tool handle 210, which not only ensures the concentricity of the tool handle 210 and the connecting head 120, but also improves the fixing efficiency. Then, the positioning ring 250 is slid so that the tooth grooves 251 on the positioning ring 250 are engaged with the racks 260 on the outer sides of the rotating ring 240 and the connecting head 120 to limit the rotation of the rotating ring 240. The threaded sleeve ring 270 is rotated to abut against the positioning ring 250 to move and maintain the position of the positioning ring 250, greatly improving the disassembly and assembly efficiency.
