[0002] The CNC four-axis rotary table is an accessory installed on the original machine tool. It can further expand the processing range of the original machine tool and enable it to complete more complex processing tasks. The use of the CNC four-axis rotary table can increase the degree of freedom of the workpiece during the processing, improve the processing accuracy and efficiency. It can realize the complex processing of the workpiece, meet the processing requirements of various workpieces, improve production efficiency and reduce production costs.

[0003] Although the existing CNC four-axis turntable meets the processing requirements of a variety of workpieces, it only has a single station for clamping, which leads to the need to frequently pause processing to install and disassemble workpieces in cases of mass production and short time for parts processing, affecting production efficiency. At the same time, because the fixture and the bridge plate are separate structures, the fixture needs to be installed on the bridge plate by means of screws or other fixing methods. In the case of loose screws or worn positioning holes, the position of the fixture during the processing is likely to change, thereby affecting the processing accuracy and product quality. Therefore, the utility model proposes a CNC four-axis turntable with a multi-station fixture that is integrally formed with a bridge plate. Summary of the invention

[0006] A multi-station CNC four-axis turntable comprises a bridge plate and a CNC turntable and a tailstock respectively arranged at both ends of the bridge plate; the bridge plate is integrally formed with a plurality of flat-nose pliers bases, and a movable pliers body which can slidably cooperate is provided on the flat-nose pliers base.

[0007] Furthermore, the plurality of flat-nose pliers bases are distributed on both sides of the bridge plate.

[0008] Furthermore, the movable pliers body and the flat-nose pliers base are respectively provided with a first step groove and a second step groove for matching with each other.

[0009] Furthermore, two ends of the bridge plate are fixedly connected to the base and one side of the CNC turntable through a rotating shaft and a transition plate respectively.

[0010] Furthermore, the outer side of the transition plate is provided with scale lines, and the CNC turntable is provided with indicator marks matching the scale lines.

[0011] Furthermore, a limiting groove is provided in the flat-nose pliers base, and the limiting groove is slidably matched with the movable pliers body through a screw rod.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] In this embodiment, refer to Figure 1-Figure 3 The invention specifically implements a multi-station CNC four-axis turntable, which includes a bridge plate 1 and a CNC turntable 2 and a tailstock 3 respectively arranged at both ends of the bridge plate 1. The bridge plate 1 is integrally formed with a plurality of flat-nose pliers bases 4, and a movable pliers body 5 that can slide and cooperate is arranged on the flat-nose pliers base 4. Multiple parts can be installed on the bridge plate 1 for processing.

[0020] Furthermore, threaded holes for installing accessories such as V-shaped blocks are respectively provided on the mating surfaces of the flat-nose pliers base 4 and the movable pliers body 5. When encountering parts such as cylinders that are inconvenient to clamp, the corresponding accessories can be installed through the threaded holes to achieve the clamping effect.

[0021] Furthermore, a plurality of flat-nose pliers bases 4 are distributed on both sides of the bridge plate 1, making full use of the rotatable characteristic of the CNC four-axis turntable so that more fixtures can be installed for processing.

[0022] Furthermore, the movable pliers body 5 and the flat-nose pliers base 4 are respectively provided with a first step groove 6 and a second step groove 7 for matching with each other. The shapes of the first step groove 6 and the second step groove 7 enable the flat-nose pliers to clamp tools at a low position, thereby increasing the processing range of parts.

[0023] Furthermore, both ends of the bridge plate 1 are fixedly connected to the base and one side of the CNC turntable 2 through the rotating shaft 8 and the transition plate 9. The rotating shaft 8 is connected to the base by a bearing, and the transition plate 9 is threadedly fixed on the rotating shaft of the CNC turntable 2, so that the bridge plate 1 can rotate as the CNC turntable 2 rotates.

[0024] Furthermore, the outer side of the transition plate 9 is provided with scale lines 10, and the numerical control turntable 2 is provided with indicator marks 11 that match the scale lines 10, so as to accurately control the rotation angle and position of the parts during operation.

[0025] Furthermore, a limit groove 12 is provided in the flat-nose pliers base 4, and the limit groove 12 is slidably matched with the movable pliers body 5 through a screw rod 13. The screw rod 13 is fixed in the limit groove 12 by a bearing, so that the screw rod 13 can only rotate in situ, and the movable pliers body 5 is matched with the screw rod 13 by a self-locking nut, and the movable pliers body 5 is driven to slide in the limit groove 12 by the rotation of the screw rod 13. After the rotation stops, the self-locking nut fixes the movable pliers body 5 by friction, so as to achieve the effect of clamping and loosening parts.

[0026] Furthermore, one end of the screw rod 13 is provided with a handle interface 14 for adjusting the movable clamp body 5. When installing or removing parts, the handle is inserted into the handle interface 14 and rotated to achieve the effect of clamping and loosening the parts. The handle is directly removed before processing to reduce the radius range of the bridge plate 1 when rotating.

[0027] The beneficial effects of the utility model are as follows: through the cooperation of the plurality of flat-nose pliers bases 4 and the movable pliers body 5 on the bridge plate 1, multiple parts can be clamped for batch processing in one processing process, and the frequency of installing and disassembling workpieces is reduced. The production efficiency of the CNC four-axis turntable is improved. At the same time, the plurality of flat-nose pliers bases 4 integrally formed on the bridge plate 1 make the size accuracy and position accuracy of the flat-nose pliers bases 4 consistent, reduce the influence of the parts caused by the fixture installation, and improve the practicality of the CNC four-axis turntable.
