Description

Technical Field

[0001] The invention relates to the technical field of deburring and cutting, and in particular to a dust suction type deburring and cutting device based on robot operation. Background Art

[0002] As we all know, deburring is an indispensable and key link in the precision machining process of parts, and its processing effect is directly related to the final quality, overall performance and market competitiveness of the product. With the vigorous rise of industrial automation technology, deburring equipment based on robot operation has gradually emerged; with the help of the robot's precise, stable and efficient motion control capabilities, combined with various professional deburring tools, a new chapter in the deburring process has been opened. Among them, polishing treatment using a polishing wheel and polishing liquid at the robot execution end is one of the more common methods, especially in the field of metal products. At the end of the processing chain of metal parts, through polishing operations, not only can the surface burrs be effectively removed, so that the workpiece reaches the flatness required by the design, but also its surface gloss can be greatly improved.

[0003] However, the existing robot-operated deburring equipment will inevitably produce a large amount of debris during the polishing process due to the high-speed rotation of the polishing wheel and the intense friction with the workpiece surface. These debris are very easy to fly and scatter, causing serious pollution to the working environment. The metal dust and other debris in the workshop not only interfere with the normal production process, but also seriously endanger human health. In addition, it is extremely difficult to clean up the scattered debris. If it is accidentally mixed into other workpieces being processed or precision equipment, it is very likely to cause secondary pollution, causing a series of chain reactions such as scratches on the workpiece, jamming or even damage to the equipment, resulting in production interruptions and a surge in the defective rate, causing huge economic losses to the company.

[0004] In addition, the equipment is not compatible with workpieces of different materials and different burr characteristics. During the deburring process, the workpiece surface is often easily damaged due to excessive polishing force, affecting the product dimensional accuracy and appearance quality. Excessive wear of consumables may also affect the deburring quality. Therefore, there is an urgent need for a robot-operated vacuum deburring cutting equipment to overcome the problems in the existing technology. Summary of the invention

[0010] As a further feature of the present invention, the buffer mechanism also includes a transverse support rod fixedly connected between the two rotating brackets, and two symmetrically arranged sliding sleeve plates are slidably sleeved on the transverse support rod.

[0016] As a further feature of the present invention, a movable hole is provided on the inner wall of the bottom side of the connecting cavity, and the buffer support arm movably passes through the movable hole.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, the robot drives the cutting and grinding head to move, and the grinding motor drives the cutting and grinding head to rotate, so that the burrs on the surface of the workpiece can be removed by cutting. At the same time, the dust suction pump can be used to collect the debris in the grinding into the dust collection container through the dust suction hose and the dust suction hood. In this way, the debris can be vacuumed during the deburring operation, reducing the occurrence of debris flying around during the deburring operation.

[0019] 2. In the present invention, when the cutting and grinding head exerts too much grinding force on the workpiece during the polishing process, the cutting and grinding head can move upward to buffer. When the buffer arm moves upward, the gear in the rotating groove moves upward as a whole and meshes with the spur rack for transmission. When the gear rotates, the first buffer spring on the central axis will be deformed by torque. In this way, the deformation of the first buffer spring can greatly consume a part of the excessive grinding pressure.

[0020] 3. In the present invention, when the buffer arm moves upward, the movable block and the connecting seat move upward and hydraulically compress the hydraulic damper. In this way, the hydraulic damping of the hydraulic damper can further offset and damp a part of the excessive grinding pressure; when the connecting seat moves upward, the sliding seat and the linkage block are driven to move upward as a whole by rotating the connecting rod to buffer the activity. At the same time, the two sliding seats can be moved away from each other and the second buffer spring can be squeezed by rotating the connecting rod. When the two sliding seats move away from each other, the third buffer spring is stretched. In this way, the cooperation of the second buffer spring and the third buffer spring can further play the role of buffering and dissipating energy;

[0021] 4. In the present invention, when the linkage block moves up for buffering, it also drives the rotating bracket to move up and squeezes the arched buffer plate. When the arched buffer plate is squeezed, it prompts the linkage rod to move the two sliding plates away from each other and compresses the fourth buffer spring. In this way, the deformation of the arched buffer plate and the fourth buffer spring can further achieve the buffering effect. Moreover, when the arched buffer plate is squeezed, it will expand to both sides. When the arched buffer plate is squeezed and expanded, it will prompt the buffer airbag to be compressed. In this way, the air pressure compression of the buffer airbag can make the overall buffering effect better.

[0022] To sum up, the robot-operated vacuum deburring and cutting equipment is not only convenient for polishing and deburring the workpiece by the robot, but also convenient for vacuuming and collecting debris during the deburring process to prevent the debris from flying around and polluting the working environment and endangering human health; it also has a good buffering function during the deburring process of workpieces of different materials by setting up multiple buffer mechanisms to cooperate with each other, avoiding damage to the workpiece surface due to excessive polishing force during deburring, thereby affecting the product dimensional accuracy and appearance quality, ensuring the overall deburring quality effect is better, and greatly meeting people's use needs.

[0036] As a further implementation, the buffer mechanism also includes a transverse support rod 154 fixedly connected between the two rotating brackets 14, and two symmetrically arranged sliding plates 152 are slidably sleeved on the transverse support rod 154. The top sides of the two sliding plates 152 are respectively rotatably connected with inclined linkage rods 151, and the two linkage rods 151 are cross-arranged, and the inclined top ends of the linkage rods 151 are rotatably connected to the inner wall of the top side of the arched buffer plate 15; the two sliding plates 152 are fixedly connected with a fourth buffer spring 153 on the side away from each other, and the other end of the fourth buffer spring 153 is fixedly connected to the inner side of the rotating bracket 14, and the fourth buffer spring 153 is sleeved on the transverse support rod 154.

[0039] Among them, sliding blocks 13 are provided at both ends of the linkage block 12, sliding grooves 17 are provided on the inner walls on both sides of the connecting cavity 301, and the sliding blocks 13 are slidably installed in the sliding grooves 17; a movable hole 302 is provided on the bottom inner wall of the connecting cavity 301, and the buffer support arm 4 movably passes through the movable hole 302.

[0040] like Figure 1-6 The shown device is a vacuum deburring and cutting device based on robot operation. When in use, the robot 1 drives the universal robot arm 2, the mounting head 3 and the cutting and grinding head 7 to move as a whole, and the grinding motor 6 is used to drive the cutting and grinding head 7 to rotate. The high-speed rotation of the cutting and grinding head 7 can be used to remove burrs on the surface of the workpiece; at the same time, the dust pump 801 can work and the dust hose 802 and the dust hood 803 can be used to collect the debris in the grinding into the dust collection container 8.

[0041] As a further implementation, when the cutting and grinding head 7 generates too much grinding force on the workpiece during the polishing process, the cutting and grinding head 7, the grinding motor 6, the mounting frame 5 and the buffer arm 4 will move upward as a whole to buffer. When the buffer arm 4 moves upward, the gear 402 in the rotating groove 401 will move upward as a whole and mesh with the spur rack 403 for transmission; when the gear 402 rotates, the first buffer spring 405 on the central axis 404 will be deformed by torque, so that a part of the excessive grinding pressure can be greatly consumed through the deformation of the first buffer spring 405; at the same time, when the buffer arm 4 moves upward, the movable block 9 and the connecting seat 903 move upward and hydraulically compress the hydraulic damper 10, so that a part of the excessive grinding pressure can be further offset and damped through the hydraulic damping of the hydraulic damper 10; when the connecting seat 903 moves upward, the sliding seat 12 and the linkage block 12 are driven to move upward as a whole to buffer by rotating the connecting rod 11, and at the same time, the connecting seat 903 can be driven upward by rotating the connecting rod 11 to buffer the movement. The movable connecting rod 11 makes the two sliding seats 122 move away from each other and squeeze the second buffer spring 123. When the two sliding seats 122 move away from each other, the third buffer spring 124 is also stretched. In this way, the cooperation of the second buffer spring 123 and the third buffer spring 124 can further play a role in buffering and energy dissipation; at the same time, when the linkage block 12 moves up for buffering, it also drives the rotating bracket 14 to move up and squeezes the arched buffer plate 15. When the arched buffer plate 15 is squeezed, it prompts the linkage rod 151 to move the two sliding plates 152 away from each other and compress the fourth buffer spring 153. In this way, the deformation of the arched buffer plate 1 and the fourth buffer spring 153 can further play a buffering effect; and when the arched buffer plate 15 is squeezed, it will also expand to both sides. When the arched buffer plate 15 is squeezed and expanded, it will prompt the buffer airbag 16 to be compressed. In this way, the air pressure compression of the buffer airbag 16 can make the overall buffering effect better. Finally, the present invention is not only convenient for using robots to perform polishing and deburring operations on workpieces, but also convenient for vacuuming and collecting the debris when a large amount of debris is generated during the operation between the cutting and grinding head 7 and the workpiece surface during the deburring process, so as to prevent the debris from flying around and polluting the working environment, endangering human health and normal work; and, through the mutual cooperation of multiple buffer mechanisms, it also has a good buffering function in the deburring process of workpieces of different materials, avoiding damage to the workpiece surface due to excessive polishing force during deburring, thereby affecting the product dimensional accuracy and appearance quality, ensuring the overall deburring quality effect is better, and greatly meeting people's use needs.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
