Description

Technical Field

[0001] The utility model relates to the technical field of lathe tool rests, in particular to a compound tool-feeding turret CNC lathe. Background Art

[0002] The compound tool-feeding turret CNC lathe is a high-precision CNC machine tool with multiple functions and can be used to process workpieces of complex shapes. The machine tool adopts a turret structure and can be equipped with a variety of cutting tools to achieve the switching and combination of different processing procedures. The CNC system controls the motion trajectory and processing parameters of the turret, and can accurately control the cutting position and cutting depth to ensure processing accuracy and quality. The compound tool-feeding turret CNC lathe has the characteristics of high speed, high precision and high efficiency. It can achieve high-speed cutting and improve processing efficiency. The turret's rapid tool change and cutting speed adjustment functions make the processing process more efficient and save time costs. Secondly, the positioning accuracy and repeated positioning accuracy of the machine tool are very high, which can meet the accuracy requirements of the workpiece. Through the precise control of the CNC system, millimeter-level processing accuracy can be achieved to ensure the quality and precision requirements of the workpiece. In addition, the compound tool-feeding turret CNC lathe also has a variety of processing functions, such as turning, drilling, tapping, milling, etc., which can meet the various processing needs of complex workpieces and reduce the process and processing time. The compound tool-feeding turret is an important component installed on the compound tool-feeding turret CNC lathe for assembling and switching different types of cutting tools. Its function is to realize the switching and combination of different processing procedures to meet the processing requirements of complex workpieces. The turret is usually composed of a cutter disc, a tool hole and a tool. The cutter disc is the main part of the turret and can be fixed or replaceable. It is equipped with multiple tool holes for installing and fixing cutting tools. Different types of tools can be installed in appropriate tool holes according to processing requirements and process requirements. The main function of the compound tool-feeding turret is to realize the switching and combination of cutting tools. By replacing the cutter disc or directly replacing the cutting tool on the fixed turret, the operator can quickly switch different types of tools to meet the needs of different processing procedures. In addition, the compound tool-feeding turret can also realize the automatic operation of the turret through the control of the CNC system. The operator can set the motion trajectory and processing parameters of the turret through programming to realize automatic switching and adjustment, improve work efficiency and processing accuracy.

[0003] However, the traditional compound tool-feeding turret has more turning tools installed on it than the traditional turret tool disc, and they need to be installed and adjusted one by one, so the installation time is longer. This will increase the production cycle and affect production efficiency. In addition, the installation process is cumbersome and requires precise installation and adjustment of the tools. If the operator operates improperly or errors occur, the tool installation will be inaccurate, affecting the processing accuracy and quality, which also requires the operator to spend more time to complete these operations. The time cost of switching and adjustment is increased, and production efficiency is reduced. At the same time, there are more tools installed on the compound tool-feeding turret, and there are greater forces and vibrations during the cutting process, which will increase the wear of the tools, require more frequent tool changes, and increase production costs.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a compound tool-feeding turret CNC lathe, which has the following beneficial effects:

[0015] 1. The composite tool-feeding turret CNC lathe uses a tool holder seat structure, a screw structure, and a transmission device in coordination. Compared with the traditional technical structure, this structure is automatically driven by the transmission device, and the tool holder seat can accurately fix the turning tool on the turret seat, avoiding the influence of the operator's technical level and experience in the traditional fixing process, and ensuring the consistency of the fixing force. Secondly, the transmission device moves the tool holder seat to a position matching the turret seat, ensuring that the direction and position of the turning tool are completely matched with the turret seat, avoiding position deviations caused by manual operation errors. At the same time, the tool holder seat firmly fixes the turning tool on the turret seat by tightening bolts, providing stable support.

The device can firmly fix the tool body direction on the turret seat through the structure of the tool holder seat and the fastening bolt, thereby avoiding the occurrence of shaking in the direction of the tool body. The tool holder seat is used as the fixing position of the tool, and the tool is firmly fixed to the turret seat through the fastening bolts, which effectively limits the movement of the tool during the processing. This fixing method can provide more stable cutting conditions, reduce tool vibration and changes in the direction of the tool body, thereby improving the stability and accuracy of the processing process.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The compound tool-feeding turret CNC lathe comprises a turret base 1, a turret plate 2 and a turret seat 3. The turret plate 2 is rotatably mounted on the turret base 1. Figure 4As shown, the turret disc 2 is fixedly provided with six or more turret seats 3 in the circumferential direction, and a fixed groove 4 is provided between every two turret seats 3. A turning tool is fixedly installed in the fixed groove 4. The fixed groove 4 is the position where the turning tool is installed, and the turning tool is fixed on the turret seat 3 through the fixed groove 4. The design of the fixed groove 4 allows the turning tool to be firmly placed on the turret seat 3, and can withstand the cutting force and vibration during the processing, ensuring the stability of the turning tool during the processing. And the setting of the fixed groove 4 also provides the possibility of position adjustment. Through the length and position of the fixed groove 4, the position of the turning tool on the turret seat 3 can be adjusted to meet different processing requirements. According to the specific workpiece and processing requirements, the position of the turning tool can be adjusted to match the contour of the workpiece, the cutting angle, etc., to improve the processing accuracy and efficiency. A sliding groove 5 perpendicular to the fixed groove 4 is provided on the surface of the fixed groove 4, a screw rod 6 is arranged in the sliding groove 5, a device groove 7 is coaxially provided at the center of the turret plate 2, six or more transmission devices 8 are arranged in the device groove 7 along the circumferential direction of the turret plate 2, the screw rod 6 passes through the inner wall of the inner side of the sliding groove 5 and is connected to the transmission device 8, a tool handle seat 9 is arranged on the screw rod 6, and the tool handle seat 9 is fixedly connected to the position of the tool handle of the turning tool, such as Figure 5 As shown, the design and fixing method of the shank seat 9 can provide the support and stability required for the turning tool. The shank is fixed to the shank seat 9 by tightening the bolts 12 to ensure the stability of the turning tool during the processing. The transmission device 8 drives the screw 6 to drive the shank seat 9 to slide along the direction of the screw 6. The fixed groove 4 is provided with two or more screw holes 10 perpendicular to the surface of the fixed groove 4 on both sides of the sliding groove 5. A raised disc-shaped fixed disk 11 is also coaxially arranged in the center of the equipment groove 7, and the outer wall of the fixed disk 11 fixes the transmission device 8. The shank seat 9 wraps the position of the turning tool shank. The shank seat 9 is provided with a concave structure, which matches the turning tool shank, and tightening bolts 12 are arranged at both ends of the concave structure. The sliding distance of the shank seat 9 is less than the radius of the turret seat 3. The sliding distance of the shank seat 9 is greater than the length of the fixed groove 4.

[0025] Working principle: When the device is used, the transmission device 8 will first drive the screw 6 to rotate and drive the handle seat 9 to move to a position close to the outside of the turret disk 2. Then, the tail of the turning tool to be installed will be inserted into the handle seat 9, and the turning tool will be fixed by the fastening bolts 12 at both ends of the handle seat 9. Then the transmission device 8 will drive the handle seat 9 to move to the side close to the transmission device 8, so that the direction and position of the blade of the turning tool match the turret seat 3. The matching position depends on the model of the turning tool. Repeating the above movement can complete the preliminary fixation of each turning tool on the turret disk 2. Through the automatic drive of the transmission device 8, the handle seat 9 can accurately fix the turning tool on the turret seat 3, avoiding the influence of the operator's technical level and experience in the traditional fixing process, and ensuring the consistency of the fixing force. Secondly, the transmission device 8 moves the handle seat 9 to a position matching the turret seat 3, ensuring that the direction and position of the blade of the turning tool are completely matched with the turret seat 3, avoiding position deviation caused by manual operation errors. Most importantly, the tool holder seat 9 firmly fixes the turning tool on the turret seat 3 through the fastening bolts 12, providing stable support. Compared with the traditional fixing method, this structure can better limit the movement of the turning tool during the processing, reduce the vibration of the tool and the change of the blade direction, thereby improving the stability and processing accuracy of the processing; if the turning tool does not match the width of the fixing groove 4, a fixing structure between the fixing groove 4 and the turning tool is installed, and the position of the turning tool in the tool holder seat 9 is adjusted by the fastening bolts 12 to keep the turning tool stable. The installed fixing structure can be fixed through the screw holes 10 on the surface of the fixing groove 4. The turning tool installed on the turret plate 2 through the tool holder seat 9 has the blade direction fixed during the working process due to this structure. The traditional turning tool fixing structure usually fixes the direction perpendicular to the turning tool blade. This structure can only provide limited support when fixing the blade direction, which easily causes the blade to shake during the processing. However, through the structure of the tool holder seat 9 and the fastening bolts 12, the blade direction of the turning tool can be firmly fixed on the turret seat 3, thereby avoiding the shaking of the blade direction. The tool holder seat 9 is used as a fixing position for the tool, and the turning tool is firmly fixed to the turret seat 3 by the fastening bolts 12, which effectively limits the movement of the turning tool during the processing. This fixing method can provide more stable cutting conditions, reduce tool vibration and changes in the direction of the blade, thereby improving the stability and accuracy of the processing process.
