Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically a CNC lathe cutting device. Background Technology

[0002] CNC cutting refers to a new control method where workpiece instructions (or programs) for controlling machine tools or equipment are given in digital form. When instructions are provided to the control device of a CNC automatic cutting machine, the machine can automatically cut according to the given program. Cutting devices, as an important tool, are widely used in manufacturing, construction, agriculture, and other fields. Whether cutting metal or non-metal materials or machining precision parts, CNC lathe cutting devices are indispensable.

[0003] Traditional CNC lathe cutting devices typically have their cutting tools or laser heads fixed in a single direction (such as vertical or horizontal), allowing them to perform straight or fixed-angle cutting. If oblique cutting or complex contour machining is required, operators need to manually adjust the tool angle or change the fixture, resulting in low efficiency and difficulty in guaranteeing accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a CNC lathe cutting device to solve the problem that the cutting tools or laser heads of traditional CNC lathe cutting devices mentioned in the background art are usually fixed in a single direction (such as vertical or horizontal), and can only perform straight line or fixed angle cutting. If oblique cutting or complex contour processing is required, the operator needs to manually adjust the tool angle or change the fixture, which is inefficient and difficult to guarantee accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC lathe cutting device, comprising a worktable, a moving part, and a cutting part:

[0006] The movable part is located on the top of the workbench. The movable part has a transverse movable frame located on the side of the workbench. A longitudinal movable frame is slidably mounted on the top of the transverse movable frame. The cutting part is located inside the movable part. The cutting part has a lifting frame slidably mounted on the bottom of the lifting frame. A rotating frame is rotatably mounted on the bottom of the rotating frame. A cutting blade is rotatably mounted inside the rotating frame. An adjusting block is slidably mounted on the bottom of the adjusting block. The adjusting rod is rotatably connected to the rotating frame. The movement of the adjusting block drives the adjusting rod to rotate, thereby controlling the rotation of the rotating frame.

[0007] By adopting the above technical solution, multi-angle adjustment of the cutting blade can be achieved. The lateral movement of the adjusting block drives the adjusting rod to rotate, thereby adjusting the tilt angle of the rotating frame, so that the cutting blade can adapt to the cutting needs in different directions and improve processing flexibility.

[0008] Preferably, the moving part also has a lead screw a that is laterally rotatably disposed inside the transverse moving frame. There are two lead screws a, which pass through the bottom of the longitudinal moving frame and are threadedly connected to the longitudinal moving frame.

[0009] By adopting the above technical solution, the lead screw a can be rotated by motor a, causing the longitudinal moving frame to slide laterally along the transverse moving frame, thereby achieving precise movement of the cutting blade in the X-axis direction and improving processing accuracy.

[0010] Preferably, the moving part further includes a drive shaft a rotatably disposed inside the transverse moving frame, with drive bevel teeth a at both ends of the drive shaft a, and a transmission bevel tooth a at the end of the lead screw a near the drive shaft a, with the two transmission bevel teeth a respectively meshing with the two drive bevel teeth a, and a motor a is disposed on the side of the transverse moving frame, with the output end of the motor a connected to the drive shaft a.

[0011] By adopting the above technical solution, the motor a can drive the drive shaft a to rotate, and the meshing transmission between the drive bevel gear a and the transmission bevel gear a can make the two lead screws a rotate synchronously, ensuring the smooth movement of the longitudinal moving frame and avoiding jamming caused by uneven force on one side.

[0012] Preferably, the moving part also has a lead screw b vertically rotatably disposed inside the longitudinal moving frame. Two lead screws b are provided, and the two lead screws b pass through both ends of the lifting frame and are threadedly connected to the lifting frame.

[0013] By adopting the above technical solution, the screw b can be rotated by the motor b, so that the lifting frame slides vertically along the longitudinal moving frame, thereby achieving precise lifting and lowering of the cutting blade in the Z-axis direction and adapting to processing needs at different heights.

[0014] Preferably, the moving part further includes a drive shaft b rotatably disposed inside the longitudinal moving frame, with drive bevel teeth b at both ends of the drive shaft b, and a transmission bevel tooth b at the end of the lead screw b near the drive shaft b, with the two transmission bevel teeth b respectively meshing with the two drive bevel teeth b, and a motor b disposed on the side of the longitudinal moving frame, with the output end of the motor b connected to the drive shaft b.

[0015] By adopting the above technical solution, the motor b can drive the drive shaft b to rotate, and the meshing transmission between the drive bevel gear b and the transmission bevel gear b can make the two lead screws b rotate synchronously, ensuring the smooth lifting of the lifting frame and avoiding the tilting problem caused by uneven force on one side.

[0016] Preferably, the cutting part also has a lead screw c that is laterally rotatably disposed inside the lifting frame. The lead screw c passes laterally through the adjusting block and is nested and threadedly connected to the adjusting block. The lifting frame is equipped with a motor c, and the output end of the motor c is connected to the lead screw c.

[0017] By adopting the above technical solution, the motor c drives the lead screw c to rotate, causing the adjusting block to move laterally along the lifting frame. In turn, the adjusting rod drives the rotating frame to rotate, thereby realizing the angle adjustment of the cutting blade and meeting the cutting requirements of different inclined planes.

[0018] Preferably, the bottom center of the lifting frame is rotatably connected to the top of the rotating frame, the rotating frame is located directly above the workbench, one end of the adjusting rod is rotatably connected to the bottom of the adjusting block, and the end of the adjusting rod away from the adjusting block is rotatably connected to the side of the rotating frame. A motor d is provided on the side of the rotating frame, and the output end of the motor d is connected to the cutting blade.

[0019] By adopting the above technical solution, the cutting blade can be directly driven to rotate at high speed by the motor d. At the same time, the movement of the adjusting block causes the adjusting rod to drive the rotating frame to rotate, realizing the multi-angle tilting of the cutting blade, improving processing adaptability, and ensuring cutting accuracy and efficiency.

[0020] Compared with the prior art, the beneficial effects of this utility model are: by setting a cutting part, the cutting blade can be adjusted at multiple angles; by moving the adjusting block laterally, the adjusting rod is rotated, thereby adjusting the tilt angle of the rotating frame, so that the cutting blade can adapt to the cutting needs in different directions and improve processing flexibility; by driving the lead screw C to rotate through the motor C, the adjusting block moves laterally along the lifting frame, thereby driving the rotating frame to rotate through the adjusting rod, thus realizing the angle adjustment of the cutting blade.

[0031] The moving part 2 is located on the top of the workbench 1. The moving part 2 has a transverse moving frame 201 located on the side of the workbench 1. A longitudinal moving frame 207 is slidably mounted on the top of the transverse moving frame 201. The cutting part 3 is located inside the moving part 2.

[0033] Please see Figure 3 , Figure 4 and Figure 5This embodiment provides a technical solution: a CNC lathe cutting device, including a moving part 2, a transverse moving frame 201, and a longitudinal moving frame 207.

[0034] Inside the transverse moving frame 201, there are two lead screws a202 that rotate. The two lead screws a202 pass through the bottom of the longitudinal moving frame 207 and are threadedly connected to the longitudinal moving frame 207. The lead screws a202 can be driven to rotate by the motor a206, so that the longitudinal moving frame 207 slides laterally along the transverse moving frame 201, thereby achieving precise movement of the cutting blade 306 in the X-axis direction and improving processing accuracy.

[0035] A drive shaft a204 is rotatably mounted inside the transverse moving frame 201. Drive bevel gears a205 are located at both ends of the drive shaft a204. A transmission bevel gear a203 is located at the end of the lead screw a202 near the drive shaft a204. The two transmission bevel gears a203 mesh with the two drive bevel gears a205 respectively. A motor a206 is mounted on the side of the transverse moving frame 201. The output end of the motor a206 is connected to the drive shaft a204. The working principle of the motor a206 is based on electromagnetic induction and Lorentz force. The motor a206 generates force in a magnetic field through current, thereby driving mechanical movement. This is existing technology and will not be elaborated further. The motor a206 can drive the drive shaft a204 to rotate. The meshing transmission between the drive bevel gears a205 and the transmission bevel gears a203 allows the two lead screws a202 to rotate synchronously, ensuring smooth movement of the longitudinal moving frame 207 and avoiding jamming caused by uneven force on one side.

[0036] Inside the longitudinal moving frame 207, there are two lead screws b208 that rotate. The two lead screws b208 pass through both ends of the lifting frame 301 and are threadedly connected to the lifting frame 301. The lead screws b208 can be driven to rotate by the motor b212, so that the lifting frame 301 slides vertically along the longitudinal moving frame 207, thereby achieving precise lifting and lowering of the cutting blade 306 in the Z-axis direction to adapt to processing requirements at different heights.

[0037] A drive shaft b210 is rotatably mounted inside the longitudinal moving frame 207. Drive bevel gears b211 are located at both ends of the drive shaft b210.

A motor b212 is mounted on the side of the longitudinal moving frame 207. The output end of the motor b212 is connected to the drive shaft b210. The working principle of the motor b212 is based on electromagnetic induction and Lorentz force. The motor b212 generates force in a magnetic field through current, thereby driving mechanical movement. This is existing technology and will not be elaborated further. The motor b212 can drive the drive shaft b210 to rotate. The meshing of the drive bevel gears b211 and transmission bevel gears b209 enables the two lead screws b208 to rotate synchronously, ensuring the smooth lifting and lowering of the lifting frame 301 and avoiding tilting problems caused by uneven force on one side.

[0039] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a CNC lathe cutting device, including a cutting section 3, an adjusting block 304, and a rotating frame 305.

[0040] A lead screw c302 is rotatably mounted inside the lifting frame 301. The lead screw c302 passes laterally through the adjusting block 304 and is nested and threadedly connected to the adjusting block 304. A motor c303 is installed inside the lifting frame 301. The output end of the motor c303 is connected to the lead screw c302. The working principle of the motor c303 is based on electromagnetic induction and Lorentz force. The motor c303 generates force in the magnetic field through current, thereby driving mechanical movement. The above is the prior art and will not be elaborated further below. The motor c303 can drive the lead screw c302 to rotate, so that the adjusting block 304 moves laterally along the lifting frame 301. In turn, the adjusting rod 308 drives the rotating frame 305 to rotate, thereby realizing the angle adjustment of the cutting blade 306 to meet the cutting needs of different bevels.

[0041] The bottom center of the lifting frame 301 is rotatably connected to the top of the rotating frame 305, which is located directly above the worktable 1. One end of the adjusting rod 308 is rotatably connected to the bottom of the adjusting block 304, and the end of the adjusting rod 308 away from the adjusting block 304 is rotatably connected to the side of the rotating frame 305. A motor d307 is installed on the side of the rotating frame 305, and the output end of the motor d307 is connected to the cutting blade 306. The working principle of the motor d307 is based on electromagnetic induction and Lorentz force. The motor d307 generates force in the magnetic field through current, thereby driving mechanical movement. The above is the prior art and will not be elaborated further. The cutting blade 306 can be directly driven to rotate at high speed by the motor d307. At the same time, the movement of the adjusting block 304 causes the adjusting rod 308 to drive the rotating frame 305 to rotate, realizing the multi-angle tilting of the cutting blade 306, improving processing adaptability, and ensuring cutting accuracy and efficiency.

[0042] Working principle: First, the device is powered on. Then, the workpiece to be processed is fixed on the worktable 1. Then, the drive shaft a204 is rotated by the motor a206, which drives the drive bevel gear a205 to mesh with the transmission bevel gear a203, causing the two lead screws a202 to rotate synchronously. This causes the longitudinal moving frame 207 to slide laterally along the transverse moving frame 201, achieving precise positioning of the cutting blade 306 in the X-axis direction. Next, the drive shaft b210 is rotated by the motor b212, which drives the drive bevel gear b211 to mesh with the transmission bevel gear b209, causing the two lead screws b208 to rotate synchronously. The motor drives the lifting frame 301 to slide vertically along the longitudinal moving frame 207, achieving precise lifting and lowering of the cutting blade 306 in the Z-axis direction. Then, the motor c303 drives the lead screw c302 to rotate, causing the adjusting block 304 to move laterally along the lifting frame 301. The adjusting rod 308 drives the rotating frame 305 to rotate, adjusting the tilt angle of the cutting blade 306 to adapt to the cutting requirements of different inclined surfaces. Finally, the motor d307 directly drives the cutting blade 306 to rotate at high speed. Combined with the X-axis, Z-axis and angle adjustment, it achieves multi-directional precise cutting of the workpiece, improving processing efficiency and accuracy.
