Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and more specifically, to a CNC machine tool for processing mechanical parts. Background Technology

[0002] As a prominent representative of modern industrial manufacturing, CNC machine tools play an indispensable role in the manufacturing field due to their high degree of automation and precision. Their core lies in a sophisticated program control system. This system, like a highly intelligent conductor, can precisely process programs containing control codes or conforming to specified instructions. These programs, after logical analysis, are converted into coded digital representations and then quickly and accurately input into the CNC device via information carriers such as disks and optical fibers. Once the program is input, the digital signals undergo complex calculations and processing, and then, based on the processing results, various precise control signals are issued to accurately guide every step of the machine tool's movement, ensuring that each operation strictly follows the predetermined program, thereby achieving precise machining of mechanical parts. However, despite the powerful functions of CNC machine tools, the machining of mechanical parts still relies heavily on the assistance of fixtures. The purpose of fixtures is to prevent mechanical parts from moving or shaking during machining. However, current fixture designs often have some limitations. Since mechanical parts often need to be machined from multiple angles, the parts need to be constantly flipped and adjusted during the machining process in order to ensure that each surface is accurately processed. Such operations are not only cumbersome and inefficient, but more importantly, they may have a certain impact on machining accuracy. Utility Model Content

[0011] As a preferred technical solution of this utility model

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a second motor, whose output shaft is connected to a screw rod to rotate the screw rod, causing a slider to move on the screw rod. The slider's movement drives a moving block to move along a track groove, allowing the clamping gripper to flip while moving. This enables flipping processing of parts during machining.

Sliding teeth one drives the protrusion to move inside the slide groove, so that sliding teeth one is fixed to the machine tool base plate. This achieves simple cleaning and the cleaning device is not easy to fall off or be damaged. Compared with traditional devices, the precise movement of sliding teeth one and two ensures that brush plates one and two can cover every corner of the machine tool base plate, cleaning without dead angles and improving cleaning efficiency. The tight combination of the protrusion and the slide groove not only ensures the stability of the cleaning device during movement, but also effectively prevents the risk of the device falling off or being damaged, thus improving the reliability of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a CNC machine tool for machining mechanical parts, including a machine tool base plate 2. Baffles 25 are fixedly installed on the front and back of the top center position of the machine tool base plate 2. A spiral rod 18 is fixedly installed between the two baffles 25. A slider 19 is slidably sleeved on the outer surface of the spiral rod 18. A fixing plate 24 is fixedly installed on the left side of the slider 19. A flipping block 16 is rotatably installed on the left side of the fixing plate 24. A hydraulic cylinder 17 is fixedly sleeved inside the flipping block 16, and the right side of the hydraulic cylinder 17 passes through the flipping block 16, the fixing plate 24 and the slider 19. A clamping gripper 15 is fixedly installed on the left side of the hydraulic cylinder 17. A connecting block 22 is rotatably installed on the right side of the slider 19, and one end of the connecting block 22 is fixedly connected to the hydraulic cylinder 17. A moving block 21 is fixedly installed on the other end of the connecting block 22. A machine tool table 1 is fixedly installed at the bottom of the machine tool base plate 2.

[0024] The operator starts motor 2 30. The output shaft of motor 2 30 drives the screw rod 18 to rotate. The rotation of the screw rod 18 causes the slider 19 to slide backward. The slider 19 drives the fixed plate 24, the flipping block 16, the hydraulic cylinder 17, and the clamping gripper 15 to slide together. The output shaft of the hydraulic cylinder 17 extends and retracts to control the clamping gripper 15 to clamp the parts. The sliding of the slider 19 causes the linkage block 22 to move. The movement of the linkage block 22 causes the moving block 21 to move inside the track groove 20, so that the clamping gripper 15 completes the flipping while moving.

[0025] By starting motor 30, the output shaft of motor 30 is connected to the screw rod 18, which drives the screw rod 18 to rotate, causing the slider 19 to move on the screw rod 18. The movement of the slider 19 drives the moving block 21 to move along the track groove 20, so that the clamping gripper 15 completes the flipping while moving. This achieves the ability to flip the parts during processing. Compared with traditional devices, the newly designed equipment can handle more types of parts, especially those that require double-sided processing, which greatly improves processing efficiency, reduces the workload of workers, reduces labor intensity, and also helps to improve the safety of the working environment.

[0026] Among them, brush plate 7 and brush plate 8 are slidably installed on the surface of the machine tool base plate 2. Sliding gear 3 and sliding gear 4 are fixedly installed on the left side of brush plate 7 and brush plate 8. Slide rail 9 is fixedly installed on the left side of the machine tool base plate 2, and brush plate 7 and brush plate 8 are slidably installed on the outer surface of slide rail 9. Gear 5 is rotatably installed between sliding gear 3 and sliding gear 4, and gear 5 meshes with sliding gear 3 and sliding gear 4. Protrusion 11 is fixedly installed at the bottom of sliding gear 3. Slide groove 10 is opened at the top left side of the machine tool base plate 2, and protrusion 11 is slidably installed inside slide groove 10. Motor 6 is fixedly installed on the right side of gear 5, and the output shaft of motor 6 passes through the machine tool base plate 2. Motor slot 26 is opened inside the machine tool base plate 2, and motor 6 is fixedly installed inside motor slot 26.

[0027] The operator starts motor 6, and the output shaft of motor 6 drives gear 5 to rotate. The rotation of gear 5 drives sliding teeth 3 and 4 to move towards or away from each other. When sliding teeth 3 moves, it drives the protrusion 11 to move inside the slide groove 10. The movement of sliding teeth 3 and 4 drives brush plates 7 and 8 to move on the surface of the machine tool base plate 2.

[0028] By starting motor 6, sliding teeth 3 and 4 move brush plates 7 and 8 on the surface of the machine tool base plate 2. Sliding tooth 3 moves the protrusion 11 inside the slide groove 10, thus fixing sliding tooth 3 to the machine tool base plate 2. This achieves a simple cleaning process, and the cleaning device is not easily detached or damaged. Compared with traditional devices, the precise movement of sliding teeth 3 and 4 ensures that brush plates 7 and 8 can cover every corner of the machine tool base plate, cleaning without dead angles and improving cleaning efficiency. The tight combination of the protrusion and the slide groove not only ensures the stability of the cleaning device during movement, but also effectively prevents the risk of the device detaching or being damaged, improving the reliability of the equipment.

[0029] The machine tool base plate 2 has a waste collection groove 12 on its top, and a waste collection drawer 13 is slidably installed inside the machine tool base plate 2 and is slidably installed at the bottom of the waste collection groove 12.

[0030] A waste collection trough 12 is provided on the top of the machine tool base plate 2. When working, brush plate 7 and brush plate 8 sweep the waste into the waste collection trough 12. The waste is collected in the waste collection trough 12 by the waste collection drawer 13. Compared with traditional devices, the cleaning and waste collection processes are integrated. While cleaning the waste, the waste is directly collected to the designated area without additional operation or tools, which greatly improves the cleaning efficiency.

[0031] Among them, a machine tool partition 23 is fixedly installed at the top center of the machine tool base plate 2, and a limit groove 14 is opened inside the machine tool partition 23, and a hydraulic cylinder 17 is slidably installed inside the limit groove 14.

[0032] By starting the motor 30, the screw rod 18 rotates, and through a series of actions, the hydraulic cylinder 17 moves inside the limiting groove 14, thereby achieving the purpose of limiting. Compared with traditional devices, this ensures the stability and consistency of the hydraulic cylinder 17 during movement, reduces errors caused by vibration or impact, and this operation method is simple and intuitive, reduces the skill requirements of operators, and improves work efficiency.

[0033] The machine tool base plate 2 has a track groove plate 28 fixedly installed on the top and the track groove plate 28 is fixedly installed on the right side of the machine tool partition 23. The track groove plate 28 has a track groove 20 inside and the moving block 21 is slidably installed inside the track groove 20.

[0034] By starting motor 30, the output shaft of motor 30 drives the screw rod 18 to rotate. Through a series of coordination, the moving block 21 moves inside the track groove 20. Due to the V-shaped design of the track groove 20, when the moving block 21 moves to the lowest end, it can accurately drive the connecting block 22 to flip through gravity and the guiding effect of the track groove, thereby realizing the flipping of the gripper 15. This flipping process is both efficient and precise, ensuring that the gripper 15 can accurately reach the predetermined position. Compared with traditional devices, this flipping process is both efficient and precise, ensuring that the gripper 15 can accurately reach the predetermined position, improving the accuracy and efficiency of operation.

[0035] Among them, the machine tool base plate 2 has a body 27 fixedly installed on its surface, the back of the machine body 27 has a motor protective shell 29 fixedly installed, the motor protective shell 29 has a motor 30 fixedly installed inside, and the output shaft of the motor 30 is fixedly connected to the screw rod 18.

[0036] By starting motor 2 30, motor 2 30 runs inside the motor protective housing 29, thereby achieving the purpose of protecting the motor and effectively preventing external objects, dust, moisture, etc. from entering the motor, thus reducing the risk of motor damage.

[0037] Among them, the waste collection tank 12 is set as three, which are distributed from front to back on the surface of the machine tool base plate 2.

[0038] With the start-up device, the machine tool table 1 is fixedly installed at the bottom of the machine tool base plate 2, achieving the purpose of stabilizing the device. Since there are three waste collection troughs 12, waste can be collected in full. The three waste collection troughs 12 can collect waste generated at different locations at the same time, improving the efficiency of waste collection. This design allows waste to be cleaned up in a timely manner, avoiding interference with the processing process and further improving processing efficiency.

[0039] Working principle and usage process of this utility model:

[0040] The operator starts motor 2 30. The output shaft of motor 2 30 drives the screw rod 18 to rotate. The rotation of the screw rod 18 causes the slider 19 to slide backward. The slider 19 drives the fixed plate 24, the flipping block 16, the hydraulic cylinder 17, and the clamping gripper 15 to slide together. The output shaft of the hydraulic cylinder 17 extends and retracts to control the clamping gripper 15 to clamp the parts. The sliding of the slider 19 causes the linkage block 22 to move. The movement of the linkage block 22 causes the moving block 21 to move inside the track groove 20, so that the clamping gripper 15 completes the flipping while moving.

[0041] The operator starts motor 6, and the output shaft of motor 6 drives gear 5 to rotate. The rotation of gear 5 drives sliding teeth 3 and 4 to move towards or away from each other. When sliding teeth 3 moves, it drives the protrusion 11 to move inside the slide groove 10. The movement of sliding teeth 3 and 4 drives brush plates 7 and 8 to move on the surface of the machine tool base plate 2.
