[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Reference Figures 1-5 This embodiment provides a turret mount and a power turret, including: Turret base 1, on which a transmission mechanism is provided for driving the turret to rotate; The transmission mechanism includes: Motor 11 is fixedly mounted on the outer end face of turret base 1; The drive shaft 12 is rotatably mounted inside the turret base 1 and is driven to rotate by the motor 11. Two levers 13 are arranged in a cross pattern and securely mounted on the drive shaft 12; The drive shaft 14 is rotatably mounted inside the turret base 1. Two drive discs 15 are fastened to the drive shaft 14. Each drive disc 15 has multiple drive pins arranged circumferentially. When the lever 13 rotates, it will move the drive pins on the drive disc 15, thereby driving the drive shaft 14 to rotate. The first gear 16 is fastened onto the drive shaft 14; The turret shaft 17 is rotatably mounted inside the turret base 1. A second gear 18 is fastened to the turret shaft 17, and the second gear 18 meshes with the first gear 16. The turret 19 is connected to the end of the turret shaft 17 and is rotatably mounted outside the turret base 1; In this embodiment, the drive shaft 12 is rotatably mounted inside the turret base 1 and is driven to rotate by the motor 11. The motor transmits power to the drive shaft, causing the drive shaft 12 to rotate. Two levers 13 are arranged in a cross pattern and securely mounted on the drive shaft 12. As the drive shaft 12 rotates, the levers 13 rotate, which actuates the transmission pin on the transmission disk 15. Since the transmission pin is fixed on the transmission disk 15, it drives the transmission shaft 14 to rotate. The first gear 16 is securely mounted on the transmission shaft 14. As the transmission shaft 14 rotates, the first gear 16 also rotates. The rotation of the first gear 16 drives the second gear 18 to rotate, thereby causing the turret shaft 17 to rotate around its own axis. 9 is connected to the end of the turret shaft 17 and is rotatably mounted outside the turret base 1. When the turret shaft 17 rotates, it drives the turret 19 to rotate as well, thereby realizing the rotation of the turret for tool changing and positioning. The transmission mechanism of this turret base and power turret has relatively few main components and a simpler structure. The simple structure makes the manufacturing process easier and reduces the requirements for machining accuracy and assembly technology, thereby reducing the difficulty of manufacturing and assembly and improving production efficiency. This turret base and power turret reduce the number of easily worn and deformable parts, reducing failures caused by wear and deformation of parts, improving the reliability of the turret, and reducing machine tool downtime.

[0018] As a preferred embodiment of the above technical solution, such as Figures 4 to 5 As shown, a connecting plate 21 is provided at the bottom of the turret spindle 17, a guide plate 22 is provided at the bottom of the connecting plate 21, a positioning post 23 is provided on the guide plate 22, a fitting groove is provided on the turret 19, a guide groove is provided in the fitting groove, and a positioning groove is provided in the guide groove. The connecting plate 21 cooperates with the fitting groove, the guide plate 22 cooperates with the guide groove, and the positioning post 23 cooperates with the positioning groove. In this embodiment, the multi-stage fit between the connecting plate 21 and the mounting groove, the guide plate 22 and the guide groove, and the positioning pin 23 and the positioning groove can improve the tighter and more stable connection between the turret 19 and the turret shaft 17. The multi-stage fit structure can withstand larger torque and load, and is less prone to loosening or falling off when the turret 19 performs rapid tool changes and machining operations, thus improving the reliability of the turret operation. The multi-stage fit structure can distribute the stress and load generated during the rotation of the turret 19 to various mating parts, avoiding local stress concentration, thereby reducing component damage caused by stress concentration and extending the service life of the turret and the turret shaft.

[0019] Specifically, such as Figures 4 to 5 As shown, a plurality of locking screws 24 are arranged in a circular pattern in the guide groove, and a plurality of locking screw holes 25 are arranged in a circular pattern on the guide plate 22. In this embodiment, the guide plate 22 is tightly fixed in the guide groove by the cooperation of the locking screw 24 and the locking screw hole 25. This prevents the turret 19 from shifting due to external forces such as cutting force and vibration during the machining process, ensuring that the turret 19 always maintains a precise machining position and improving the accuracy of tool changing and machining. The clamping action of the locking screw 24 makes the guide plate 22 fit tightly with the guide groove, reducing the gap between the two, thereby reducing the shaking of the turret 19 during rotation and fixing. The stable position of the turret 19 helps to improve the surface quality of the machined parts and reduce machining errors caused by turret shaking.

[0020] More specifically, such as Figures 4 to 5 As shown, three positioning pins 26 are arranged in a circular pattern on the connecting plate 21, and three positioning holes 27 are arranged in a circular pattern in the mounting groove. In this embodiment, the cooperation of the three positioning pins 26 and the three positioning holes 27 provides precise angular positioning for the turret 19, enabling more accurate control of the installation accuracy of the turret 19 and improving the dimensional and shape accuracy of the parts. During the rotation of the turret 19, positional errors may occur due to factors such as the clearance and vibration of the transmission mechanism. The precise positioning method of the positioning pins 26 inserting into the positioning holes 27 can effectively eliminate errors and improve the processing quality.

[0021] Furthermore, such as Figures 4 to 5 As shown, multiple teeth 28 are arranged in a circular pattern in the sleeve groove, and multiple teeth 28 are arranged in a circular pattern on the connecting plate 21. The connecting plate 21 and the teeth 28 on the sleeve groove mesh with each other. In this embodiment, the meshing of multiple teeth 28 enables more precise transmission of rotation angles. This meshing ensures that the rotation angle of the turret shaft 17 is accurately transmitted to the turret 19, allowing the turret 19 to be accurately positioned at the required machining location. The meshing transmission method reduces error accumulation during transmission. In multiple tool changes and rotation operations, the position of the turret 19 is consistent each time, improving the dimensional and shape accuracy of the machined parts. The simultaneous participation of multiple teeth 28 in transmission disperses the forces generated during transmission. Compared with single-tooth or few-tooth connection methods, multi-tooth bearing reduces the load borne by each tooth, reducing tooth wear and damage, thereby improving the stability of the entire transmission structure.

[0022] Furthermore, such as Figure 1 As shown, a protective cover 31 is provided on the turret base 1, and the protective cover 31 covers the outside of the transmission mechanism; In this embodiment, the protective cover 31 can block the intrusion of dust, keep the inside of the transmission mechanism clean, and ensure the normal operation of the transmission components. The drive shaft, gears and other components in the transmission mechanism have high speed and a certain kinetic energy during operation. If personnel accidentally touch these components, it will cause cuts, abrasions and other injuries to the fingers, arms and other parts. The protective cover 31 encloses the transmission mechanism, so that personnel cannot directly contact the moving parts, reducing the risk of personnel injury and ensuring the safety of the operators.

[0023] Furthermore, such as Figure 4 As shown, a detection support plate 32 is provided inside the protective cover 31, and multiple rotation sensors 33 are provided on the detection support plate 32. The rotation sensors 33 are used to detect the rotation of the turret shaft 17. In this embodiment, the rotational speed and angle changes of the turret shaft 17 can be monitored in real time by the rotational speed sensor 33. This helps operators and the control system to accurately grasp the dynamics of the turret during the machining process and promptly detect abnormalities. The precise rotational speed data provided by the rotational speed sensor 33 allows the control system to accurately adjust the rotational parameters of the turret according to the requirements of the machining process, thereby achieving high-precision machining and improving machining quality. The rotational speed sensor 33 can continuously monitor the rotational speed change trend of the turret shaft 17. If abnormal fluctuations, gradual decreases, or increases in rotational speed are detected, it indicates that some components in the transmission mechanism are about to fail. Based on these abnormal data, early warning signals are issued to remind operators to perform maintenance and repair, avoiding sudden equipment failures during operation, which could lead to production interruptions and parts scrapping.

[0024] Furthermore, such as Figure 1 As shown, the turret base 1 is equipped with an inspection cover 34; In this embodiment, the inspection cover 34 is mounted on the turret base 1 and fixed by detachable fasteners, so that the operator can quickly and conveniently remove the inspection cover 34 when inspection or maintenance is required, exposing the internal transmission mechanism and other components; after the inspection is completed, the inspection cover 34 can be quickly installed back, reducing the inspection and maintenance time and improving the utilization rate of the equipment.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
