Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, in particular to a machine for precisely cutting the length of vacuum cleaner parts. Background Art

[0002] The vacuum cleaner parts length precision cutting machine is a device specially designed to provide precise length cutting for parts in the vacuum cleaner production process. In the manufacturing process of vacuum cleaners, the size and shape of parts are crucial to the performance of the vacuum cleaner. In order to ensure the suction power, filtration effect and overall performance of the vacuum cleaner, the length and shape of the parts must be accurate. Therefore, the use of the vacuum cleaner parts length precision cutting machine can ensure the precise cutting of parts to meet the high standards of vacuum cleaner manufacturing.

[0003] However, there are still some problems with the existing vacuum cleaner parts length precision cutting machine:

[0004] First, in order to ensure the accuracy and efficiency of cutting, existing vacuum cleaner parts length precision cutting machines generally use pneumatic chucks to clamp the workpiece during the processing process. However, the traditional three-jaw chuck performs well when clamping cylindrical parts, but its clamping effect is limited when facing non-cylindrical parts, especially rectangular parts, which leads to unstable clamping or damage to the workpiece, affecting the cutting accuracy. Although the four-jaw chuck is more suitable for clamping rectangular parts, it is relatively cumbersome when processing cylindrical parts, and it is difficult to ensure the uniform distribution of clamping force.

[0005] In order to balance this contradiction, a chuck replacement system has emerged in the market. This system allows different types of chucks to be quickly replaced according to the shape and size of the workpiece to meet the clamping needs of different parts. However, although this technology improves the flexibility and adaptability of processing, the chuck replacement system itself is relatively expensive, which increases the investment cost of the enterprise. Secondly, replacing the chuck requires a certain amount of time and manpower, which reduces production efficiency. In addition, frequent replacement of chucks will aggravate equipment wear and increase maintenance costs. For small enterprises, due to the limitations of funds and production scale, small enterprises often cannot afford such investment and maintenance costs and can only choose one chuck for workpiece clamping, which to a certain extent limits their production capacity and market competitiveness.

[0006] Secondly, with the long-term use of the precision cutting machine for the length of vacuum cleaner parts, the wear and replacement of the tool becomes an inevitable problem, and the existing technology usually adopts screw fixing and steel ball clamping mechanism to replace the tool. First of all, the screw fixing method is simple and easy to operate, but in actual operation, the operator needs to use tools such as screwdrivers for repeated operations, which not only reduces the work efficiency, but also increases the labor intensity of the operator. Since there are many splashes generated during the cutting process of vacuum cleaner parts, these splashes can easily clog the screw holes, resulting in the screws being unable to be tightened or loosened smoothly, further increasing the difficulty of maintenance. In addition, once the screw holes are clogged, they need to be cleaned, which not only increases the maintenance cost, but also causes secondary damage to the equipment. What is more serious is that if the blockage in the screw hole is not cleaned in time, the tool will loosen or even fall off during high-speed rotation, posing a serious threat to the safety of the operator and equipment.

[0007] While the steel ball clamping mechanism simplifies the tool disassembly process to a certain extent, the steel ball will be constantly vibrated and rolled inside the tool during use. This rolling will aggravate the wear between the steel ball and the clamping groove. As the wear intensifies, the clearance between the steel ball and the clamping groove will gradually increase, resulting in a decrease in the clamping force. When the clamping force is reduced to a certain level, the tool is prone to loosening or even falling off during high-speed rotation, causing safety accidents. At the same time, the steel ball clamping mechanism also has an easily overlooked problem, namely, insufficient protection for the tool and equipment. Since the steel ball constantly collides and rubs with the clamping groove during rolling, this will cause scratches or wear on the surface of the tool and equipment. These scratches or wear will not only affect the appearance quality of the equipment, but also reduce the performance and service life of the equipment. To this end, a vacuum cleaner component length precision cutting machine is proposed. Summary of the Invention

A snap-fit ​​groove is provided in the middle of the fixed disk, and a cutting knife is provided inside the snap-fit ​​groove. The outer surface of the cutting knife is provided with a plurality of snap-fit ​​grooves which are arranged in a circular and equidistant manner. A snap-fit ​​body is slidably connected to the inside of each of the arc grooves and straight grooves, and a discharge trough is provided on the side of the workbench close to the fixed table.

The shape of the clamping body is adapted to the shape of the clamping groove. The clamping body is composed of a fixing part, a baffle and a connecting rod. The fixing part is slidably connected to the inside of the clamping groove, and the connecting rod is slidably connected to the inside of the straight groove and the arc groove. The outer surface of the fixing part is fixedly connected with a rubber sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The output shaft of the clamping cylinder drives the rotating wheel to rotate, thereby causing the sliding seat and the fixed seat on the surface of the clamping cylinder to move relative to the other set of sliding seats and fixed seats corresponding to them. During this process, the clamping rod slides in the sliding seat and gradually converges toward the center, thereby effectively clamping the parts. Under the action of the clamping rod and the arc-shaped clamping block, both rectangular workpieces and cylindrical parts can obtain a stable clamping effect. Due to the improvement of the clamping method, the parts can remain stable during the processing, thereby ensuring the accuracy of the cutting. At the same time, due to the simplification of the clamping process, the processing efficiency is also greatly improved. Secondly, the dispersed clamping components reduce the skill requirements for the operators and reduce the impact of human factors on the processing quality. Finally, due to the versatility of the clamping method, the company does not need to frequently replace the chuck, thereby reducing the investment cost and maintenance cost of the equipment and improving the company's market competitiveness.

[0019] Compared with existing pneumatic chucks and their replacement systems, the decentralized clamping assembly achieves stable clamping of parts of different shapes through the design of a single mechanical structure, eliminating the need for frequent chuck replacement, thereby greatly improving production efficiency and reducing maintenance costs. Secondly, the decentralized clamping assembly also reduces the skill requirements for operators and reduces the impact of human factors on processing quality. Finally, the chuck replacement system in the existing technology is relatively expensive, increasing the investment cost of the enterprise. The decentralized clamping assembly achieves stable clamping of parts of different shapes through a single mechanical structure, eliminating the need for additional purchase and replacement of chucks, thereby reducing the investment cost of the enterprise. At the same time, the simplified clamping method also reduces the maintenance cost of the equipment.

[0020] The four clamping rods are divided into two groups with a height difference between each group of clamping rods. This avoids the problem that traditional chucks can only apply clamping force on one plane, thus avoiding the problem that the workpiece is subjected to uneven force during the clamping process, causing deformation or damage to the workpiece.

[0021] When the clamping rod moves, it applies a rotational torque to the sliding seat, which in turn compresses the rubber airbag. The compression and expansion of the air allows precise adjustment of the clamping force. On the one hand, the rubber airbag can automatically adjust the clamping force according to the material and hardness of the workpiece, ensuring that the workpiece remains stable during processing. On the other hand, the compression and expansion of the air can also reduce friction and wear between mechanical components to a certain extent, thereby extending the service life of the equipment.

[0022] Among them: when clamping a rectangular workpiece, the arc-shaped clamping block will completely enter the telescopic slot, thereby ensuring that the workpiece remains stable during the clamping process; when clamping a circular workpiece, the circular workpiece will collide with the arc-shaped clamping block and completely compress the telescopic rod, thereby enabling the arc-shaped clamping block to clamp the circular workpiece. The design of the arc-shaped clamping block and telescopic slot not only improves the adaptability and flexibility of the equipment, but also enables the equipment to simultaneously adapt to the processing needs of workpieces of various shapes.

[0023] 2. By rotating the ratchet, the clamping body can be clamped and disengaged with the cutting knife under the restriction of the straight groove and the arc groove. The multi-dimensional disassembly and assembly component improves the efficiency and safety of the tool replacement of the vacuum cleaner component length precision cutting machine. First, the decentralized clamping component eliminates the need for tools such as screwdrivers, greatly simplifies the operation process, reduces the labor intensity of operators, and significantly improves work efficiency. Secondly, since there is no need to use screws, it avoids maintenance problems and safety hazards caused by splashes blocking the screw holes. In addition, the clamping body moves stably under the restriction of the straight groove and the arc groove, ensuring the accuracy and stability of the tool during the replacement process, thereby improving processing accuracy and product quality. The semicircular and flat notch design of the clamping groove effectively solves the friction loss problem caused by the rolling of the steel ball in the existing technology, which not only reduces scratches or wear on the surface of the tool and the equipment, but also extends the service life of the equipment, and further improves the performance and appearance quality of the equipment.

[0024] Compared with traditional screw fixing and steel ball clamping mechanisms, the decentralized clamping assembly achieves rapid tool replacement by rotating the ratchet, eliminating the need for tools such as screwdrivers, significantly reducing the operator's labor intensity and improving work efficiency. Secondly, in terms of safety, since it avoids the problems of tool loosening or falling off caused by screw hole blockage and steel ball rolling, the probability of safety accidents is greatly reduced, ensuring the safety of operators and equipment. In addition, in terms of equipment protection, the semi-circular flat notch design of the clamping groove effectively reduces scratches or wear on the tool and equipment surface, extending the service life of the equipment and improving the performance and appearance quality of the equipment.

[0025] Among them: because the arc surface of the clamping body is designed to face the force-bearing side of the cutting blade, the arc surface can provide more uniform and stable support when the cutting blade is subjected to cutting force. The arc surface design not only increases the contact area between the cutting blade and the multi-dimensional disassembly and assembly component, but also reduces the stress concentration caused by uneven force, thereby effectively reducing the risk of the cutting blade loosening or falling off during the cutting process;

[0026] Among them: because one side of the notch-shaped clamping groove is also designed to face the force-bearing side of the cutter, the notch-shaped structure can provide better positioning and fixing effects, ensuring that the cutting knife can be accurately and firmly installed in place after replacement. Secondly, the notch-shaped structure can effectively disperse the impact force generated when the cutting knife is subjected to force, reducing the wear of the cutting knife and the equipment, and extending the service life;

[0027] The two side clip slots are designed to be higher than the rear side clip slots, allowing the multi-dimensional disassembly and assembly components to provide better support and fixation, ensuring that the cutting blade can be stably installed in place after replacement and is not prone to shaking or falling off. In addition, the raised design on both sides can effectively prevent splashes generated during the cutting process from entering the multi-dimensional disassembly and assembly components, reducing maintenance difficulties and safety hazards caused by blockage.

[0028] Among them: by opening the card slot, not only the cutting knife can be quickly replaced and stably installed, but also the carrying capacity of the cutting knife is significantly enhanced. As a result, the cutting knife can obtain more uniform and stable support when bearing the cutting force, reducing the stress concentration and wear caused by uneven force. At the same time, due to the reduction in the use of complex structures such as screws, the manufacturing cost and maintenance cost of the equipment are also reduced.

The output shaft of the propulsion cylinder is fixedly connected to the outer surface of the tool holder 16. The feeding mechanism 13 and the propulsion mechanism 14 are both electrically controlled to start and stop by an external controller.

[0052] The working principle of the present invention is as follows:

[0053] The following is the initial state: the rubber airbag 213 is not compressed, the output shaft of the clamping cylinder 26 is not extended, the telescopic rod 211 is not compressed, the pawl 32 is engaged with the ratchet 31, the torsion spring at the connection between the pawl 32 and the ratchet 31 is not in a tensioned state, the engaging bodies 310 are both located on one side of the arc groove 34 and the straight groove 36 close to the center of the fixed plate 35, and the engaging bodies 310 are both engaged with the engaging groove 39.

[0054] The following are the specific steps of the work:

[0055] Among them, the loading of vacuum cleaner parts:

[0056] like Figure 1 As shown, the operator manually places the vacuum cleaner parts on the loading platform, and then the operator controls the external controller to electrically control the loading mechanism 13 and start the ultrasonic sensor. At this time, the loading cylinder starts to take in air, the output shaft of the loading cylinder extends, and pushes the vacuum cleaner parts to slide in the loading platform. When the ultrasonic sensor detects that the distance between the vacuum cleaner parts and the cutting knife 38 is the predetermined cutting length, the ultrasonic sensor sends an electrical signal to the external controller, and then the external controller electrically controls the loading cylinder to close.

[0057] Among them, the fixation of vacuum cleaner parts:

[0058] like Figures 3 to 7 As shown, at this time, the operator manually controls the external controller and makes the external controller electrically control the clamping cylinder 26 to start. At this time, the clamping cylinder 26 takes in air, the output shaft of the clamping cylinder 26 extends, and the output shaft of the clamping cylinder 26 drives the rotating wheel 25 to rotate.

[0059] As the rotating wheel 25 rotates, the stable seat 27 and the sliding seat 28 located on its surface and the surface of the synchronous wheel 24 begin to move relative to the stable seat 27 and the sliding seat 28 on the opposite side, and the relative movement of the stable seat 27 and the sliding seat 28 causes the clamping rod 29 to produce a synchronous rotation trend. Since the clamping rod 29 is restricted from sliding inside the sliding seat 28, the clamping rod 29 cannot rotate freely, but is guided to slide inside the sliding seat 28 toward the side close to the stable seat 27 on the opposite side. At this time, the four clamping rods 29 gradually move toward the center of the rotating disk 22.

[0060] During this process, due to the push of the clamping cylinder 26, the relative movement between the stable seat 27 and the sliding seat 28 provides an initial driving force for the clamping rod 29. However, the driving force is restricted by the inner wall of the sliding seat 28, so that the clamping rod 29 cannot rotate freely, but is forced to slide inside the sliding seat 28. At this time, the clamping rod 29 is subjected to the sliding friction force from the inner wall of the sliding seat 28, and is also subjected to the inertia force of its own rotation. The interaction of these two forces causes the clamping rod 29 to produce a compound motion mode inside the sliding seat 28.

[0061] As the clamping cylinder 26 continues to rotate, the stable seat 27 and sliding seat 28 on its surface gradually begin to be misaligned with the stable seat 27 and sliding seat 28 on the opposite side. This misalignment causes the position of the clamping rod 29 inside the sliding seat 28 to change, thereby generating a movement tendency that conflicts with the inner wall of the sliding seat 28. At the same time, the clamping rod 29 applies a rotational torque to the sliding seat 28. In order to resist this torque, the rubber airbag 213 inside the sliding seat 28 is elastically compressed, and at the same time, the air inside it is pushed to the uncompressed side. This compression and convergence of air provides the necessary support and buffering for the stable sliding of the clamping rod 29 inside the sliding seat 28. At this time, the clamping rod 29 has more deflectable area inside the sliding seat 28. Furthermore, at this time, the four clamping rods 29 converge again toward the center of the rotating disk 22. At this time, the clamping rod 29 conflicts with the vacuum cleaner parts through the arc-shaped clamping block 212.

[0062] When the component is a rectangular component, the edge of the component contacts the arc-shaped clamping block 212 and elastically compresses the telescopic rod 211. As the arc-shaped clamping block 212 gradually enters the telescopic groove 210, the rectangular component is firmly clamped. During this process, the contact force between the edge of the rectangular component and the arc-shaped clamping block 212 is evenly distributed to the entire clamping rod 29, thereby achieving precise clamping of the rectangular component.

[0063] When the component is a circular part, since the outer surface of the circular part is smooth, its contact area with the clamping rod 29 is much smaller than that of a rectangular part. Therefore, when the circular part collides with the arc-shaped clamping block 212, although the telescopic rod 211 will also be compressed, the pressure generated is more concentrated due to the small contact area. Since the side of the telescopic groove 210 close to the arc-shaped clamping block 212 is arc-shaped, this design allows the circular part to smoothly enter the telescopic groove 210, and the telescopic rod 211 will be completely compressed, and then the circular part will be firmly clamped by the rubber airbag 213. At the same time, the circular part and the arc-shaped side of the telescopic groove 210 collide with each other, further enhancing the stability of the clamping.

[0064] Among them, the cutting of vacuum cleaner parts:

[0065] like Figures 3 to 10 As shown, after the clamping rod 29 and the arc-shaped clamping block 212 firmly clamp the part, the operator controls the external controller and electrically controls the clamping cylinder 26 to close. At this time, the operator electrically controls the external motor to start through the external controller, and the output shaft of the external motor drives the driving gear connecting rod 21 to rotate, and the driving gear connecting rod 21 drives the rotating disk 22 engaged with it to rotate in the fixed table 12. Then the operator electrically controls the propulsion mechanism 14 to start through the external controller. At this time, the propulsion cylinder on the cutting table is air-intaken, and the output shaft of the propulsion cylinder extends and pushes the tool holder 16 to slide on the guide rail 15 toward the side close to the part.

[0066] As the tool holder 16 continues to move, the cutting knife 38 thereon gradually comes into contact with the parts. Due to the arc surface design of the clamping body 310, the force-bearing side of the cutting knife 38 fits tightly with the arc surface, forming a stable support structure. This design not only increases the contact area between the cutting knife 38 and the support structure, but also makes the force distribution more uniform, thereby effectively reducing the stress concentration caused by uneven force.

[0067] At the moment when the cutting blade 38 contacts the component, due to the high-speed rotation of the component and the difference in their hardness, a certain impact force and vibration will be generated. However, due to the arc surface design of the clamping body 310, these impact forces and vibrations are effectively dispersed and buffered, thereby ensuring the stability and service life of the cutting blade 38.

[0068] As the cutting blade 38 penetrates deeper, the friction between the cutting blade 38 and the component gradually increases. At the same time, the cutting blade 38 is inevitably affected by vibration. However, this vibration is effectively controlled thanks to the support of the arc surface design. The arc surface not only disperses the impact force generated by the vibration, but also converts the vibration into sliding along the arc surface, thereby reducing the wear and loosening risk of the cutting blade 38. In addition, the notch-shaped snap-in groove 39 design also provides an important guarantee for the stable operation of the cutting blade 38. Because the notch-shaped structure provides better positioning and fixing effect, the cutting blade 38 can maintain an accurate cutting trajectory and a stable cutting depth during the cutting process. At the same time, the notch-shaped structure can effectively disperse the impact force generated by the cutting blade 38 when it is subjected to force, further reducing wear on the cutting blade 38 and the equipment.

[0069] Finally, when the parts are completely cut, they lose the support provided by the whole body and will naturally fall into the chute. At this time, the operator can easily collect the cut parts for subsequent processing or assembly.

[0070] Among them, to the replacement of the cutting knife 38:

[0071] like Figures 8 to 10 As shown, when the cutting blade 38 is worn due to long-term use, the operator first electrically controls all electrical appliances to turn off through an external controller, and then the operator manually turns the pawl 32. Based on the lever principle, the pawl 32 rotates, and the torsion spring at the connection between the pawl 32 and the ratchet 31 is in a tensioned state. At this time, the pawl 32 is no longer engaged with the ratchet 31, and then the operator turns the handle to rotate the ratchet 31.

[0072] When the ratchet 31 rotates, the locking body 310 in the arc groove 34 tends to rotate synchronously, but because the locking body 310 is also restricted by the linear groove 36, in order to comply with the rotation of the rotating disk 33, the locking body 310 will slide in the arc groove 34 and the linear groove 36 toward the side away from the center of the fixed disk 35. At this time, the locking body 310 is no longer engaged with the locking groove 39.

[0073] The operator manually removes the cutting blade 38 from the snap-fit ​​groove 37 and places a new cutting blade 38 into the snap-fit ​​groove 37. The operator then reverses the above steps and engages the engaging body 310 with the engaging groove 39 again. At this time, the replacement of the cutting blade 38 is completed.
