Description

Technical Field

[0001] This utility model relates to the field of machining, specifically to a milling structure for a composite lathe. Background Technology

[0002] Milling is a highly efficient machining method that uses a rotating, multi-edged cutting tool to cut a workpiece. During operation, the cutting tool rotates while the workpiece moves; the workpiece can also be stationary, but the rotating cutting tool must still move. Milling machine tools include horizontal milling machines, vertical milling machines, and large gantry milling machines.

[0003] Existing milling mechanisms mostly use synchronous belt drives to provide power to the transmission rod on the milling shank during milling, which in turn drives the drill chuck to rotate. As a result, the torque value is unstable, and the mechanism occupies a large area, making it impractical and limiting its applicability. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide a milling structure for a composite lathe.

[0005] The purpose of this utility model is achieved through the following means: a milling structure for a composite lathe, comprising a rotary motor, a support frame, a milling shank, a drill chuck, and a universal joint movably mounted on the support frame. The rotary motor and the milling shank are respectively mounted at both ends of the support frame, and both ends of the universal joint movably connect to the rotary motor and the milling shank, respectively. The support frame is in the shape of a through-hole, and the drill chuck is mounted at the end of the milling shank away from the support frame.

[0006] Furthermore, the universal assembly includes a left drive member, a movable member, a right drive member, and two universal blocks. The ends of the left drive member and the right drive member opposite to each other are movably connected to the upper and lower ends of the two universal blocks, respectively. The left and right ends of the movable member are movably connected to the front and rear ends of the two universal blocks, respectively.

[0007] Furthermore, the left drive component and the right drive component each have a first movable groove extending inward at their opposite ends, and the movable component has a second movable groove at both ends. By setting the first movable groove and the second movable groove, damage caused by collision between the left drive component, the movable component, the right drive component and the two universal blocks during movement can be avoided.

[0008] Furthermore, a transmission rod is installed between the left drive component and the drill chuck. The left drive component drives the transmission rod to rotate, which in turn drives the drill chuck to rotate.

[0009] Furthermore, the drill chuck is provided with a groove for mounting cutting tools.

[0010] Furthermore, the back of the milling shank is provided with a mounting block for mounting on a machine tool.

[0011] Furthermore, the surface of the drill chuck is provided with several grooves for anti-slip purposes. By setting the grooves, the surface roughness of the drill chuck can be increased, thereby improving the anti-slip ability.

[0012] The beneficial effects of this utility model are as follows: by installing the universal component on the support frame, the torque value can be kept stable. By installing the rotary motor and milling shank at both ends of the support frame, not only is the area occupied saved, but it can also be installed around the spindle. Therefore, it is easy to install, highly practical, and has a wide range of applications. Attached Figure Description

Detailed Implementation

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0018] Please see Figures 1-3 The present invention relates to a milling structure for a composite lathe, comprising a rotary motor (Figure 1), a support frame (Figure 2), a milling shank (Figure 3), a drill chuck (Figure 4), and a universal joint movably mounted on the support frame (Figure 2). The rotary motor (Figure 1) and the milling shank (Figure 3) are respectively mounted at both ends of the support frame (Figure 2), and both ends of the universal joint movably connect to the rotary motor (Figure 1) and the milling shank (Figure 3). The support frame (Figure 2) is a through-type structure, and the drill chuck (Figure 4) is mounted at the end of the milling shank (Figure 3) away from the support frame (Figure 2).

[0019] The universal assembly includes a left drive member 5, a movable member 6, a right drive member 7, and two universal blocks 8. The opposite ends of the left drive member 5 and the right drive member 7 are movably connected to the upper and lower ends of the two universal blocks 8, respectively. The left and right ends of the movable member 6 are movably connected to the front and rear ends of the two universal blocks 8, respectively. Each of the opposite ends of the left drive member 5 and the right drive member 7 has a first movable groove 9 extending inward. Both ends of the movable member 6 have second movable grooves 10. By providing the first and second movable grooves 9 and 10, collisions between the left drive member 5, the movable member 6, the right drive member 7, and the two universal blocks 8 during movement can be prevented from causing damage. A transmission rod 11 is installed between the left drive member 5 and the drill chuck 4. The left drive member 5 drives the transmission rod 11 to rotate, which in turn drives the drill chuck 4 to rotate.

[0020] The back of the milling shank 3 is provided with a mounting block 13 for mounting on a machine tool. The drill chuck 4 is provided with a chuck groove 12 for mounting a cutting tool. The surface of the drill chuck 4 is provided with several anti-slip grooves 14. By setting the grooves 14, the surface roughness of the drill chuck 4 can be increased, thereby improving the anti-slip ability.

[0021] The working principle of this utility model embodiment is as follows: During milling, the right drive member 7 is driven to rotate by the rotary motor 1 in the figure. The right drive member 7 drives the universal block 8 near the right end of the movable member 6 to move. The universal block 8 at the right end of the movable member 6 drives the movable member 6 to rotate. The movable member 6 drives the universal block 8 at the left end to move. The universal block at the left end drives the left drive member 5 to rotate. Then, the left drive member 5 drives the transmission rod 11 to rotate, thereby driving the drill chuck 4 to rotate.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
