Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, and in particular to a cutting device for precision mechanical processing. Background Art

[0002] The cutting device for precision machining is one of the key equipment in modern manufacturing. It is usually composed of cutting tools, tool holders or tool holder systems, drive devices, and cooling and lubrication systems. The cutting tool is its core component and is made of high-hardness and high-wear-resistant materials, such as cemented carbide and ceramics, to meet the cutting and processing needs of various materials. It can accurately remove excess materials on the workpiece and achieve high-precision size and shape processing. The drive device provides power for the cutting tool to ensure that it works at an appropriate speed and feed speed. The cooling and lubrication system cools the tool and workpiece, reduces friction, and washes away chips, thereby improving processing quality and tool life. This cutting device plays an important role in many high-precision fields such as aerospace, automobile manufacturing, and electronic equipment. It can achieve micron or even nanometer processing accuracy, providing a strong guarantee for the production of high-quality, high-performance precision parts.

[0003] The existing mechanical seals are extremely weak during installation and use, especially in the adjustment and expansion of processing methods. Specifically, when faced with different types of processing tasks, such as processing workpieces of different materials and shapes, the existing cutting device is difficult to flexibly change the processing method according to actual needs. It cannot autonomously adaptively adjust the cutting parameters. Operations such as changing the cutting speed in real time according to the hardness of the material and optimizing the cutting path according to the shape of the workpiece are difficult to achieve. In addition, when dealing with some special processing requirements, such as the need for high-precision micro-machining or the need to achieve surface processing of different roughness in a specific area, the existing device also lacks the corresponding expansion capabilities and cannot quickly switch to the appropriate processing mode, which greatly limits its application effect in complex and changeable precision machining scenarios, reduces the controllability of machining efficiency and product quality, and is difficult to meet the growing diversified and high-precision machining needs of the modern manufacturing industry, which has brought certain adverse effects on people's use process. In order to solve the shortcomings of the existing technology, we propose a cutting device for precision machining. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the metal parts are stably clamped by the clamping structure to ensure that the parts do not move during the cutting process, thereby improving the processing accuracy. The second servo motor, the third servo motor and the slide blocks, threaded rods, electric telescopic rods and other components in the adjustable cutting structure work together to achieve precise adjustment of the cutting tool holder position. The cutting tool can be replaced to meet different processing requirements. At the same time, the coordinated movement and position adjustment of the overall structure improve the processing flexibility.

[0018] 2. In the present invention, the first driving wheel is driven by the fourth servo motor, which in turn drives the first driven wheel and the cylindrical gear to rotate, so that the cleaning brush is activated to realize automatic cleaning of the debris in the cutting area. The two sets of mirror-symmetrically distributed structures and the cylindrical gears meshing with each other ensure the stable operation and efficient cleaning of the cleaning brush. The cleaning brush can be adjusted in angle by the deflection frame and the rotating frame to meet different cleaning requirements. The setting of the collecting trough and the auxiliary wedge block can effectively guide the debris into the collecting trough to keep the processing area clean. The setting of the positioning block enables the debris near the cutting tool holder to be better cleaned, thereby improving the cleaning effect, reducing the adverse effects of the debris on the processing accuracy and equipment operation, and providing a clean working environment for the cutting process.

[0019] 3. In the present invention, the clamping action is precisely controlled by the fifth servo motor to realize automated operation, improve production efficiency, and reduce manual labor intensity. The cooperation of the rotating block, the auxiliary rod and the clamping block can stably clamp the workpiece from four directions to ensure that the workpiece will not shake during the processing, greatly improving the processing accuracy. The cross-shaped limit groove makes the sliding of the clamping block more stable and accurate, and can adapt to workpieces of different shapes and sizes, enhancing the versatility of the device. On the whole, the clamping structure provides reliable fixation for cutting processing and ensures the safety and stability of processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1, as Figure 1-Figure 7As shown, when it is necessary to cut the metal part, the metal part to be cut is first placed in the clamping structure 5 for clamping, and then the first electric telescopic rod 101 is started to make the first electric telescopic rod 101 telescopic and drive the electric clamping claw 102 to move, and then the metal part is contacted and clamped by the electric clamping claw 102, and then the second servo motor 31 on one side of the device base 1 is started, and then the second threaded rod 32 is driven to rotate through the output shaft end of 31, so that the third slider 33 threadedly connected to the outer wall close to the second servo motor 31 moves, and the second limiting rod 36 fixedly installed on the upper part of the third slider 33 close to the second servo motor 31 plays a limiting and guiding role in the movement of the third slider 33, and at the same time, a third threaded rod 37 is rotatably installed on the upper part of the side of the third slider 33 away from the second limiting rod 36, and one end of the third threaded rod 37 can be detachably mounted After the third servo motor 34 is started, it drives the third threaded rod 37 to rotate, so that the fourth slider 35 threadedly connected to the outer wall near the third servo motor 34 moves, and the side of the fourth slider 35 away from the third threaded rod 37 is slidably connected to the outer wall of the second limit rod 36 to ensure that the fourth slider 35 moves smoothly. Then, the second electric telescopic rod 38 detachably installed on the upper surface of the side of the fourth slider 35 away from the third slider 33 adjusts the position of the cutting tool holder 39 by telescoping, and the cutting tool 310 connected to the middle part of the cutting tool holder 39 by bolts can be replaced to meet different processing requirements. In addition, the side of the third slider 33 away from the second threaded rod 32 is slidably connected to the first limit rod 24, and the outer wall of the side of the third slider 33 close to the fixed block 220 is detachably connected to the telescopic ends of the two telescopic sleeve rods 23, so as to realize the coordinated movement and position adjustment of the overall structure;

[0039] When the processing method of the metal part needs to be changed, the third slider 33 is first driven to move by the rotation of the second servo motor 31. When the third slider 33 continues to move in the direction close to the fixed block 220, the telescopic sleeve 23 is first squeezed and contracted. When the telescopic sleeve 23 is contracted to the limit, since a contact signal generator is provided inside the telescopic sleeve 23, the signal generator of the telescopic sleeve 23 is started by squeezing the telescopic sleeve 23 by the third slider 33, and a signal is sent to start the sixth servo motor 213. Then, when the sixth servo motor 213 rotates, the first threaded rod 21 is driven to rotate. When the first threaded rod 21 rotates, the first bevel gear 25 is driven to rotate. Since the first bevel gear 25 is meshedly connected with the second bevel gear 26, the second bevel gear 26 is driven to rotate synchronously. The rotation of the second bevel gear 26 drives the linkage rod 27 and the second synchronous wheel 216 and the fixed column 29 driven by it to rotate. When the fixed column 29 is deflected, the second slider 211 is pushed to slide in the slide groove 212 through the auxiliary connecting rod 210. Then, when the second slider 211 stops sliding, the first servo motor 215 can be started, and then the first servo motor 215 drives the rotary hole cutting head 214 detachably connected to the first servo motor 215 to rotate, and then the metal parts are cut by the rotation of the rotary hole cutting head 214.

[0040] Embodiment 2, as Figure 8-Figure 10 As shown, first, the fourth servo motor 42 on the first support column 41 on the side of the device base 1 close to the first limit rod 24 is started, and its output shaft end drives the first driving wheel 43 to rotate, and the first driving wheel 43 drives the first driven wheel 49 to rotate through the transmission belt, and the first driven wheel 49 is connected to the cylindrical gear 410. Since two groups of structures are arranged with the cleaning brush 47 as the center, the first support column 41, the first driving wheel 43, the second support column 44, the deflection frame 45, the rotating frame 46, the first driven wheel 49, and the cylindrical gear 410 are mirror-symmetrically distributed, and the two cylindrical gears 410 are meshed with each other and relatively offset in position, when the first driven wheel 49 rotates, it drives the cylindrical gear 410 to rotate, thereby causing the cleaning brush 47 to move, and the cleaning brush 47 is moved. 47 is connected to the deflection frame 45 through a rotating frame 46. The deflection frame 45 is installed at the top of the second support column 44, so that the angle of the cleaning brush 47 can be adjusted. During the cutting process, the fourth servo motor 42 is started, and the cleaning brush 47 rotates to clean the debris generated in the cutting area, so that it falls into the collection groove 411 opened on the upper surface of the device base 1 close to the second support column 44. The auxiliary wedge block 48 set on the inner wall of one side of the collection groove 411 is used to guide the debris into the collection groove 411. At the same time, a positioning block 412 is set on the side of the device base 1 close to the first support column 41, and the cutting tool holder 39 rotates on the side of the positioning block 412 close to the cleaning brush 47, so that the cleaning brush 47 can better clean the debris near the cutting tool holder 39.

[0041] Embodiment 2, as Figure 11-Figure 12 As shown, the fifth servo motor 51 installed on the outer wall of the same side of the starter base 1 close to the second servo motor 31 drives the detachable transmission column 52 installed on its output shaft end to rotate to one side, so that the deflection column 54 fixedly installed on the side of the transmission column 52 away from the fifth servo motor 51 rotates synchronously, and the outer wall of the deflection column 54 is rotatably installed in the clamping base 53, and at this time, the rotation direction makes the ratchet teeth 59 and the tooth grooves 510 not engaged, and the deflection column 54 drives the detachable rotating block 56 installed on the end away from the transmission column 52 to rotate, The four corners of 56 are rotated to install the auxiliary rod 58 to apply pulling force, so that the auxiliary rod 58 is rotated to install the clamping block 57 on the end away from the rotating block 56 to apply pulling force, so that the clamping block 57 slides in the limiting groove 55 to achieve the clamping or loosening action of the workpiece. Then when the fifth servo motor 51 rotates in the opposite direction, it drives the transmission column 52 to rotate, and then the deflection column 54 rotates. At this time, the ratchet teeth 59 and the tooth grooves 510 engage to drive the clamping base 53 to rotate synchronously. The clamping base 53 rotates and drives the clamped metal parts to rotate at the same time.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
