Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and more particularly to a numerical control turret. Background Art

[0002] A turret is an automated device for processing mechanical equipment, usually equipped on lathes and machine tools, used to carry tools and drive the tools to process products. Multiple tools are installed on the turret. By rotating the turret to align the required tool with the workpiece and then rotating the workpiece, the workpiece can be processed.

[0003] Most of the existing turrets process by aligning the tool tip with the workpiece. However, during processing, only a single position can be processed. When processing the workpiece, it is difficult to process different positions simultaneously. After completing one processing, it is usually necessary to adjust the position to perform secondary processing on other positions, and the overall processing efficiency is easily affected. Summary of the Invention

[0004] To solve the problem that the existing turret usually needs to adjust the position to perform secondary processing on other positions after one processing, and the overall processing efficiency is easily affected, the present application provides a numerical control turret, and the specific solution is as follows.

[0005] A numerical control turret includes a turret body. A first tool holder and a second tool holder are provided on the turret body. A driving assembly is provided on the turret body corresponding to the first tool holder. The driving assembly is used to drive the first tool holder to move up and down along the length direction of the turret. The second tool holder is arranged on the side wall of the turret body, and the second tool holder is rotatably connected to the turret body. The rotation axis of the second tool holder is perpendicular to the turret body.

[0006] A first tool tip is provided on the first tool holder. The first tool tip is rotatably connected to the first tool holder. The first tool tip is used for detachably connecting a tool. A second tool tip is provided on the second tool holder. The second tool tip is fixedly connected to the second tool holder. A plurality of tool grooves are formed on the second tool tip. The tool grooves are arranged at intervals along the circumferential direction of the second tool tip.

[0007] By adopting the above technical solutions, the first tool holder can move up and down along the length direction of the turret. The design of the driving assembly enables the first tool holder to accurately control the position, thereby realizing precise processing at different heights. The second tool holder is rotatably connected to the turret body, increasing the diversity of processing angles and enhancing the adaptability of the equipment. The first tool tip is rotatably connected to the first tool holder and can detachably connect the tool, facilitating the replacement of different tools to meet the various processing requirements of different products at different angles. A plurality of tool grooves are formed on the second tool tip, enabling multiple tools to be installed on the same tool tip, reducing the tool change time, improving the work efficiency, and the second tool tip and the first tool tip can cooperate to perform multiple processes on the workpiece simultaneously, further improving the overall processing efficiency.

[0008] Optionally, the driving component includes a guide rail and a lead screw. Both the guide rail and the lead screw are arranged along the vertical direction of the tower body. The guide rail is fixedly arranged on both sides of the tower body, and the lead screw is rotatably connected to the tower body. The first tool holder is slidably connected to the guide rail, and the lead screw is threadedly connected to the first tool holder. The driving component further includes a first motor, and the rotating shaft of the first motor is fixedly connected to the lead screw.

[0009] By adopting the above technical solution, the combined structure of the guide rail and the lead screw ensures the precise movement of the first tool holder in the vertical direction, improves the machining accuracy. The setting of the first motor makes the driving process more stable and reliable, reduces mechanical wear, and extends the service life of the equipment.

[0010] Optionally, a second motor is provided in the tower body corresponding to the second tool holder. The rotating shaft of the second motor is fixedly connected to the second tool holder. An installation groove is provided in the tower body corresponding to the second motor, and the second motor is embedded in the installation groove.

[0011] By adopting the above technical solution, the setting of the second motor enables the second tool holder to achieve precise angle adjustment and rapid response, and can realize the rapid tool change of the second tool holder, improving the machining accuracy and efficiency. At the same time, the second motor is embedded in the installation groove in the tower body, which not only saves space, but also protects the motor from the influence of the external environment and extends the service life.

[0012] Optionally, a driving motor is provided on the first tool head. An installation head is fixedly connected to the rotating shaft of the driving motor, and a connection groove is provided on the installation head for detachably connecting the tool.

[0013] By adopting the above technical solution, the driving motor on the first tool head can drive the installation head to rotate, thereby realizing the high-speed rotary machining of the tool, enabling the first tool head to also have a milling effect on the workpiece. The design of the connection groove on the installation head enables the tool to be conveniently loaded and unloaded, improving the tool change efficiency and flexibility.

[0014] Optionally, a positioning frame is further provided beside the tower body. An arc ring is provided on the positioning frame. A first cylinder is provided on the positioning frame corresponding to the arc ring. The piston rod of the first cylinder is fixedly connected to the arc ring. The center of the arc ring is located above the arc ring, and the arc ring is used to abut against the bottom of the workpiece.

[0015] By adopting the above technical solution, the arc ring on the positioning frame can accurately abut against the bottom of the workpiece under the drive of the first cylinder, ensuring the stability and accuracy of the workpiece during the machining process. At the same time, the design of the arc ring makes the contact surface more conform to the shape of the workpiece, reducing the damage to the workpiece surface and improving the machining quality.

[0016] Optionally, a rotating wheel is further disposed inside the arc-shaped ring. The rotating wheel is rotatably connected to the arc-shaped ring and is used to abut against the workpiece.

[0017] By adopting the above technical solution, the arrangement of the rotating wheel can reduce the friction between the workpiece and the arc-shaped ring, improve the stability during the processing, and at the same time avoid surface damage caused by direct contact, thereby ensuring the quality of the workpiece and extending the service life of the equipment.

[0018] Optionally, a side frame is further disposed beside the positioning frame. An arc-shaped ring is also provided on the side frame. An arc-shaped ring is provided on the side frame corresponding to one side of the arc-shaped ring on the positioning frame, and the arc-shaped ring is used to abut against the side of the workpiece.

[0019] By adopting the above technical solution, the arc-shaped ring on the side frame can effectively abut against the side of the workpiece, ensure the stability of the workpiece during the processing, and avoid offset or deformation caused by uneven force on the side. In addition, when used in cooperation with the arc-shaped ring on the positioning frame, the workpiece can be stably clamped from multiple angles, further improving the processing accuracy and efficiency.

[0020] Optionally, a rotating wheel is also disposed inside the arc-shaped ring of the side frame. The rotating wheel is rotatably connected to the arc-shaped ring, and the arc-shaped ring is used to abut against the side of the workpiece.

[0021] By adopting the above technical solution, the arrangement of the rotating wheel inside the arc-shaped ring of the side frame can effectively reduce the friction during the processing of the workpiece, improve the stability and processing accuracy of the workpiece. At the same time, the design of the rotating wheel rotatably connected to the arc-shaped ring makes the workpiece more stable when being clamped, reducing the risk of damage caused by uneven contact surfaces.

[0022] Optionally, a flushing pipe is further disposed inside the first cutter head. The bottom of the flushing pipe is close to the mounting head, and the top of the flushing pipe is used to connect to a water pipe. A blocking block is provided at the bottom of the flushing pipe. The blocking block is slidably connected inside the flushing pipe and can block the flushing pipe. A blocking spring is also disposed inside the flushing pipe. The blocking spring has a tendency to push the blocking block to block the flushing pipe. The bottom of the flushing pipe is arranged to align with the position of the mounting head, and an electromagnet is provided inside the mounting head. The electromagnet can adsorb the blocking block to move towards the blocking spring.

[0023] By adopting the above technical solutions, the flushing pipe can automatically open and close the water path during the processing, realizing effective cooling and cleaning of the workpiece. Specifically, when cooling or cleaning is required, the electromagnet is energized to generate magnetic force to attract the plugging block to overcome the acting force of the plugging spring, so that the plugging block moves away from the bottom of the flushing pipe, thereby opening the water path. The water flow passes through the flushing pipe to reach near the mounting head, effectively cooling and cleaning the tool. When cooling or cleaning is not required, the electromagnet is de-energized, and the plugging spring pushes the plugging block to reset, re-plugging the flushing pipe to prevent water leakage. At the same time, when the electromagnet starts, it can also adsorb the tool, thereby improving the stability of the tool installation. This design not only improves the efficiency of cooling and cleaning, but also avoids waste of water resources and ensures the stable operation of the machine tool.

[0024] Optionally, two synchronously rotating rotating shafts are provided on the drive motor in the first tool head. One rotating shaft is fixedly connected to the mounting head, and a drive gear is provided on the other rotating shaft. A pressurizing gear is provided in the flushing pipe. A transmission rod is provided between the pressurizing gear and the drive gear. One end of the transmission rod is fixedly connected to the pressurizing gear, and the other end of the transmission rod penetrates through the flushing pipe to be provided with a bevel gear. The bevel gear meshes with the drive gear, and the transmission rod is rotatably connected to the flushing pipe.

[0025] By adopting the above technical solutions, after the tool is installed, the electromagnet can clean and cool the tool after starting. At this time, when milling is required, the pressurizing gear can be driven by the motor. The pressurizing gear drives the water in the flushing pipeline by rotating, thereby increasing the flow rate of the sprayed water, improving the impact force during cleaning, and improving the cleaning effect on the workpiece.

[0026] In summary, the present application has at least the following beneficial effects:

[0027] The present application solves the problem that the turret in the prior art usually needs to adjust the position for secondary processing of other positions after completing one processing, and the overall processing efficiency is easily affected. The present application sets two tool seats and tool heads, and processes the workpiece simultaneously through the two tool heads, and can perform multiple processes such as milling and broaching on the workpiece at the same time, and can process the workpiece from multiple angles at the same time.

[0028] The present application also fixes the position of the workpiece by setting a positioning frame, thereby reducing the situation of workpiece deviation during processing and further improving the processing accuracy.

[0029] The present application also cleans the tool during processing by setting a flushing pipe, and cleans the chips generated during processing, further improving the processing quality. Brief Description of the Drawings

A driving assembly 12 is arranged on the tower body 1 corresponding to the first tool holder 2. The driving assembly 12 is used to drive the first tool holder 2 to move up and down along the length direction of the turret. The second tool holder 3 is arranged on the side wall of the tower body 1. The second tool holder 3 is rotatably connected to the tower body 1. The rotating shaft of the second tool holder 3 is perpendicular to the tower body 1. Specifically, during implementation, the first tool holder 2 and the second tool holder 3 are respectively arranged on two adjacent surfaces of the tower body 1.

[0046] Working principle: By setting the first cutter head 21 and the second cutter head 32, the workpiece can be machined simultaneously by the first cutter head 21 and the second cutter head 32. At the same time, the first cutter head 21 can rotate and can machine the workpiece from multiple angles. Moreover, the first cutter head 21 can also rotate the tool and can perform various machining operations.

A rotating wheel 411 is also provided inside the arc-shaped ring. The rotating wheel 411 is rotatably connected to the arc-shaped ring. The rotating wheel 411 is used to abut against the workpiece. In specific implementation, the positioning frame 4 is separately provided beside the tower body 1. The positioning frame 4 can play a role in supporting and positioning the workpiece, further improving the stability of the workpiece during processing.

[0050] Working principle: The basic working principle is the same as that of Embodiment 1, but the positioning frame 4 and the side frame 43 are added. Both the positioning frame 4 and the side frame 43 can support the workpiece, further increasing the positioning effect on the workpiece and improving the stability during processing.

[0051] Embodiment 3

[0052] As Figure 4 shown, a flushing pipe 214 is also provided inside the first tool head 21. The bottom of the flushing pipe 214 is arranged close to the mounting head 212. The top of the flushing pipe 214 is used to connect to a water pipe. A blocking block 215 is arranged at the bottom of the flushing pipe 214. The blocking block 215 is slidably connected inside the flushing pipe 214 and can block the flushing pipe 214. A blocking spring 216 is also provided inside the flushing pipe 214. The blocking spring 216 has a tendency to push the blocking block 215 to block the flushing pipe 214.

In specific implementation, the flushing pipe 214 flushes at the position corresponding to the tool processing. The electromagnet 217 can both adsorb the tool and adsorb the blocking block 215 to release the blockage of the flushing pipe 214. When the tool is installed during processing, it can be adsorbed by the electromagnet 217, and at the same time, the water at the flushing pipe 214 can be drained out.

[0053] As shown Figure 4 in the figure, the drive motor 211 in the first cutter head 21 is provided with two synchronously rotating rotating shafts. One rotating shaft is fixedly connected to the mounting head 212, and a drive gear 125 is provided on the other rotating shaft. A pressurizing gear 218 is provided in the shower pipe 214.

Therefore, during milling, it is necessary to increase the water flow rate in the shower pipe 214 through the pressurizing gear 218, so as to improve the shower flow rate and further improve the cleaning effect on the workpiece.

[0054] Working principle: The basic working principle is the same as that of the first embodiment, but the shower pipe 214 is added to clean the workpiece, providing cooling for the tool and also reducing the situation where chips stay on the workpiece and affect the processing.
