[0021] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figs. 1 to 4 As shown, the high-speed vertical machining center provided in this embodiment of the present invention includes a support frame 1, an mounting plate 2 fixedly installed at the bottom of the support frame 1, a clamp 5 for clamping one end of a workpiece fixedly installed on the mounting plate 2, and a driving component fixedly installed on the upper part of the mounting plate 2. The clamp 5 is driven by the driving component to rotate. A fixed plate 6 is fixedly installed on the upper part of the support frame 1, and a top cone 8 is installed on the lower part of the fixed plate 6. The top cone 8 is rotatably set and cooperates with the clamp 5 to clamp both sides of the workpiece and is driven by the driving component to perform rotational machining. The top cone 8 includes a rotating part 804, which is disposed inside the fixed plate 6. A cone 803 for contacting the workpiece is fixedly magnetically levitated on the lower part of the rotating part 804.

[0024] In the aforementioned high-speed vertical machining center, the workpiece is placed between the fixture 5 and the top cone 8. The top cone 8 is moved to clamp the workpiece together with the fixture 5. At this time, both ends of the workpiece are fixed by the fixture 5 and the top cone 8 respectively, ensuring stability during the machining process. The drive unit drives the fixture 5 and the workpiece to rotate. At the same time, due to the magnetic levitation structure of the top cone 8, it can move synchronously with the rotation of the workpiece, avoiding continuous friction between the top cone 8 and the workpiece surface. This avoids the wear of the workpiece caused by friction during the machining process of the traditional top cone 8. In addition, the magnetically levitated top cone 8 reduces wear caused by other frictions when the top cone 8 rotates.

[0025] As a preferred embodiment of this utility model, the driving component includes a motor 3, which is driven by a transmission component 4 and a clamp 5. The clamp 5 consists of two pulleys and a belt.

[0026] A pulley is fixedly connected to the output shaft of motor 3. The pulley is directly driven by motor 3. The pulley at the output end of motor 3 is connected to the pulley at the drive end of fixture 5 through a belt. Power is transmitted to the pulley at the end of fixture 5 through the belt, driving fixture 5 and the fixed workpiece to rotate and process together.

[0027] In this embodiment, a slide plate 9 for mounting turning parts is slidably installed in the middle of the support frame 1. A limit screw 10 is screwed to one side of the slide plate 9, and the head of the limit screw 10 presses against the support frame 1.

[0028] The middle part of the support frame 1 is slidably installed with a slide plate 9 for installing a turning part, and the slide plate 9 can move forward and backward along the support frame 1. The position of the turning part can be quickly adjusted at different machining positions to adapt to the machining requirements of different workpieces. The head of the limiting screw 10 directly presses and contacts the support frame 1. When the limiting screw 10 is rotated to the pressing state, the slide plate 9 is fixed on the support frame 1 and the sliding is limited to maintain the stability of the turning part.

[0029] When the position of the slide plate 9 needs to be adjusted, the limiting screw 10 can be loosened, and the slide plate 9 can be freely slid on the support frame 1 to the appropriate position. After the adjustment is completed, the limiting screw 10 is tightened, and the head of the limiting screw 10 again presses the support frame 1 to firmly fix the slide plate 9, ensuring the stability of the turning part during machining.

[0030] In this embodiment, the inside of the fixed plate 6 is slidably installed with a lifting plate 802, and the upper part of the lifting plate 802 is screwed with a lifting screw 801 for driving the lifting plate 802 to lift, and the upper part of the lifting screw 801 is fixedly connected with the rotating wheel 7 penetrating through the fixed plate 6. The rotating part 804 includes an upper fixed seat 8041 fixed on the lower part of the lifting plate 802, and the rotating part 804 is driven by the lifting plate 802 to make synchronous lifting action.

[0031] In this embodiment, the inside of the upper fixed seat 8041 is provided with a cavity, the inner wall of the upper fixed seat 8041 is fixedly connected with an upper magnetic disc 8042 at the upper part, and the inside of the upper fixed seat 8041 is slidably installed with a lower magnetic disc 8043, and the lower magnetic disc 8043 is arranged in repulsion with the upper magnetic disc 8042. The lower part of the lower magnetic disc 8043 is fixedly connected with a connecting rod 8044, the lower part of the connecting rod 8044 is fixedly connected with a lower fixed seat 8045 penetrating through the upper fixed seat 8041, the lower fixed seat 8045 is hollowly arranged, the inner wall of the lower fixed seat 8045 is fixedly connected with an upper magnetic ring 8046 and a lower magnetic ring 8047 at the upper part and the lower part respectively, and the inside of the lower fixed seat 8045 is slidably installed with a suspended magnetic ring 8048, and the suspended magnetic ring 8048 is arranged in repulsion with the upper magnetic ring 8046 and the lower magnetic ring 8047 respectively, and the lower part of the suspended magnetic ring 8048 is fixedly connected with a vertebral body 803, and the vertebral body 803 extends to the outside penetrating through the lower fixed seat 8045.

[0032] The inside of the upper fixed seat 8041 is provided with a cavity, the inner wall of the cavity is fixedly connected with the upper magnetic disc 8042 at the upper part, and the lower magnetic disc 8043 is slidably installed in the cavity. The lower magnetic disc 8043 and the upper magnetic disc 8042 are arranged in repulsion by magnetic field, that is, they repel each other. When the workpiece is clamped, as the lower magnetic disc 8043 moves upward, the repulsion force forms an elastic support in the inside of the upper fixed seat 8041. The repulsion force not only clamps the workpiece, but also elastically supports the workpiece through magnetic force to avoid damage to the end of the workpiece during clamping.

[0033] The suspension magnetic ring 8048 is slidably installed in the lower fixing seat 8045, and the suspension magnetic ring 8048 is arranged in repulsion with the upper magnetic ring 8046 and the lower magnetic ring 8047 respectively, so that the suspension magnetic ring 8048 is kept in free suspension in the magnetic field of the upper and lower magnetic rings 8047, and contact with the upper magnetic ring 8046 and the lower magnetic ring 8047 is avoided. The vertebral body 803 is fixedly connected to the lower part of the suspension magnetic ring 8048, and the vertebral body 803 extends out of the lower fixing seat 8045 to the outside so as to contact the end of the workpiece.

[0034] Through the magnetic suspension structure, the vertebral body 803 can rotate synchronously when the workpiece rotates. Optionally, the bottom of the vertebral body 803 is designed as a plane instead of a top cone 8, so as to increase the contact area and the friction force, and effectively improve the synchronous rotation effect between the vertebral body 803 and the workpiece. The suspension magnetic ring 8048 is in repulsion with the upper and lower magnetic rings 8047, so that wear of the suspension magnetic ring 8048 caused by contact with the surrounding structure during long-time rotation is avoided, thereby prolonging the service life of the equipment.

[0035] Working principle of the utility model:

[0036] The workpiece is clamped by moving the top cone 8 and the clamp 5, at this time, the two ends of the workpiece are fixed by the clamp 5 and the top cone 8 respectively, so as to ensure stability during machining. The clamp 5 and the workpiece are rotated by the driving member, and the top cone 8 can move synchronously with the rotation of the workpiece due to the magnetic suspension structure of the top cone 8, so as to avoid continuous friction of the top cone 8 on the surface of the workpiece, thereby avoiding wear of the workpiece caused by friction during machining of the traditional top cone 8, and the top cone 8 installed by magnetic suspension reduces wear caused by other friction during rotation of the top cone 8.
