The I-shaped plate is slidably arranged in the inner cavity of the I-shaped groove. A driving component is connected to the bottom end of the I-shaped plate. The plurality of I-shaped plates are arranged in a circular array centered on the disc body. A clamping block is fixedly arranged at one end of the top of the I-shaped plate close to the center of the disc body. A fixing block is fixedly arranged at the other end of the top of the I-shaped plate. A screw rod is threadedly connected inside the fixing block. A groove block is rotatably arranged at one end of the screw rod close to the clamping block.

[0015] The preferred embodiments of the present utility model will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0016] The utility model provides a quick installation structure for a fixture of a numerical control lathe, which includes a disk body 1. A plurality of I-shaped plates 2 are arranged on the disk body 1. An I-shaped groove 9 that fits with the I-shaped plate 2 is formed on the outer wall of the disk body 1. The I-shaped plate 2 is slidably arranged in the inner cavity of the I-shaped groove 9. A driving component is connected to the bottom end of the I-shaped plate 2, and the driving component can control the position of the I-shaped plate 2. The plurality of I-shaped plates 2 are arranged in a circular array centered on the disk body 1. A clamping block 3 is fixedly arranged at one end of the top of the I-shaped plate 2 close to the center of the disk body 1, and a fixing block 4 is fixedly arranged at the other end of the top of the I-shaped plate 2. A screw rod 5 is threadedly connected inside the fixing block 4. A groove block 6 is rotatably arranged at one end of the screw rod 5 close to the clamping block 3. The operation of the driving component can make the plurality of I-shaped plates 2 approach or move away from each other, so that the distance between the clamping blocks 3 on the I-shaped plates 2 fits the inner diameter of the annular part. At this time, one end of the annular part is placed on the slide rail 8, and the rotating screw rod 5 can drive the groove block 6 to approach the annular part until the groove block 6 presses and fixes the annular part, realizing double internal and external fixation, and the internal and external fixations correspond to each other.

[0017] It should be noted that convex points are processed on the clamping surfaces of the clamping block 3 and the groove block 6 to increase the friction force with the annular part and make the fixation of the annular part by the fixture more stable.

[0018] Specifically, the driving component includes a turntable 10. The shaft end of the turntable 10 is rotatably arranged at the bottom end of the disk body 1. An electric push rod 11 is rotatably arranged at the bottom edge of the disk body 1 through a pin shaft. The movable end of the electric push rod 11 is rotatably arranged at the bottom edge of the turntable 10 through a pin shaft. The bottom end of the I-shaped plate 2 is rotatably arranged with a rocker 12 through a pin shaft. The plurality of rockers 12 are all rotatably arranged at the bottom edge of the turntable 10 through a pin shaft, and the plurality of rockers 12 are arranged in a circular array centered on the turntable 10. The operation of the electric push rod 11 drives the turntable 10 to rotate. At this time, the turntable 10 can drive the I-shaped plate 2 to move through the rocker 12. This driving method can drive the plurality of I-shaped plates 2 to move synchronously, so that the movement of the I-shaped plate 2 is consistent.

[0019] Specifically, a circular groove that fits with the turntable 10 is formed at the bottom end of the disk body 1. The turntable 10 rotates in the inner cavity of the circular groove. This design can hide the disk body 1, making the entire fixture structure more compact and convenient to use.

[0020] Specifically, a slide rail 8 is fixedly arranged on the top of the I-shaped plate 2 along the direction of the screw rod 5. The bottom end of the groove block 6 is slidably arranged on the outer wall of the slide rail 8. The purpose of this design is to increase the stability of the movement of the groove block 6 and prevent the groove block 6 from rotating when clamping the annular part.

[0021] Specifically, a handwheel 7 is fixedly arranged at one end of the screw rod 5 to facilitate driving the screw rod 5 to rotate.

[0022] To those skilled in the art, all the electrical components and parts in this case are common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. As long as the models are adapted to this solution and can operate normally, all the electrical components in this case are connected to their adapted power supplies through wires. And according to the actual situation, a suitable controller is selected to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the electrical components working in sequence in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in this field and will not be described for electrical control.

[0023] Working principle: First, start the electric push rod 11 according to the size of the annular part, so that the rotation of the electric push rod 11 drives the turntable 10 to rotate. At this time, the turntable 10 can drive the I-shaped plate 2 to move through the rocker 12, so that multiple I-shaped plates 2 can approach or move away from each other, and then the distance between the clamping blocks 3 on the I-shaped plates 2 fits the inner diameter of the annular part. At this time, one end of the annular part is placed on the slide rail 8, and then start the electric push rod 11 again to achieve outward expansion and fixation. At the same time, rotate the hand wheel 7, and the rotating screw rod 5 can drive the groove block 6 to approach the annular part until the groove block 6 presses the annular part tightly. This fixing method realizes double internal and external fixation, and the internal and external fixations correspond to each other. When one of the clamping blocks 3 or the groove block 6 loosens, the annular part can still be stably fixed. While ensuring the fixing quality, the rapid clamping of the annular part is realized, which is more efficient and convenient.
