Description

Technical Field

[0001] The present invention belongs to the technical field of manufacturing other metal processing machinery, and specifically relates to a polishing device for stainless steel parts. Background Art

[0002] Stainless steel parts refer to various components, products or structural parts made of stainless steel materials. For example, stainless steel pipes and pipe fittings. After the production of stainless steel pipes, the outer surface and the inner surface of the stainless steel pipes are very rough. Therefore, a polishing device is required to polish the inner and outer surfaces of the stainless steel pipes, and different polishing devices are used to process the inner and outer surfaces of the stainless steel pipes.

[0003] The patent with the publication number CN117900929 discloses a stainless steel pipe polishing device and a polishing process. It includes a frame, on which a sliding frame is movably installed, a polishing shaft is rotatably installed on the sliding frame, a driving component for driving the polishing shaft to rotate is fixedly installed on the frame, a support component is arranged at the end of the polishing shaft, a polishing head is arranged at the end of the support component, and two groups of fixing components for fixing the stainless steel pipe are arranged in front of the polishing head. This solution uses a power motor and a lead screw to cooperate to further push the sliding frame, the polishing shaft and the polishing head, and the polishing head further polishes the inner wall of the pipe to be polished. At the same time, the first articulated bracket will move along with the polishing shaft and gradually enter the pipe. When the first articulated bracket contacts the end of the pipe, the first articulated bracket and the second articulated bracket will converge towards the polishing shaft, and the sliding ring will slide and compress the compression spring; when the supporting wheel enters the conduit, the supporting wheel abuts against the inner wall of the pipe. At this time, the support component can support the polishing shaft to ensure the stability of the polishing shaft.

[0004] In the above solution, before polishing the stainless steel pipe, the stainless steel pipe needs to be fixed to the two groups of fixing components. After polishing, the stainless steel pipe needs to be disassembled before the next group of stainless steel pipes can be installed on the fixing components. The disassembly and assembly of the stainless steel pipe waste a lot of time and reduce the polishing efficiency of the stainless steel pipe. Therefore, the present invention provides a polishing device for stainless steel parts. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A polishing device for stainless steel parts according to the present invention includes a machine tool. Two groups of transmission shafts are rotatably installed in the machine tool. Two groups of sprockets are respectively arranged at both ends of the transmission shafts. The two groups of sprockets respectively mesh with two groups of chains. A number of receiving plates are arranged around between the two groups of chains. A feeding plate is arranged on the receiving plate. A driving mechanism for driving the rotation of the stainless steel pipe is arranged on the machine tool. A support frame is arranged on one side of the machine tool. A movable seat is movably installed on the support frame. One side of the movable seat is connected with a push rod. A polishing head is arranged at the end of the push rod. The driving mechanism includes a bracket. The bracket is fixedly installed on the machine tool. A cylinder for driving the lifting frame is fixedly installed on the bracket. A pressure roller is rotatably installed on the lifting frame. A first pulley is installed at the end of the pressure roller. A second pulley is rotatably connected to the lifting frame. The second pulley and the first pulley are both rotatably connected to a timing belt. A feeding groove for placing the stainless steel pipe is opened on the feeding plate. A number of rollers are rotatably installed in the feeding groove. A lead screw is rotatably installed on the support frame. The lead screw is screwed to the movable seat. The movable seat is slidably connected to the support frame. A guide sleeve for inserting the push rod is fixedly installed on the support frame; During the process of polishing the stainless steel pipe, the staff can take down the polished stainless steel pipe from the feeding plate, and at the same time place the unpolished stainless steel pipe on the vacant feeding plate, so that the polishing and taking and placing of the stainless steel pipe can be carried out simultaneously, saving the time for taking and placing the stainless steel pipe and improving the efficiency of polishing and processing the stainless steel pipe.

[0007] Preferably, the receiving plate includes a plate body. Two groups of chains are respectively connected to both ends of the plate body. A rectangular groove is opened on the plate body. A sliding rod is fixedly installed in the rectangular groove. A slider is slidably connected to the sliding rod. The slider is fixedly connected to the feeding plate. A first spring is sleeved on the sliding rod. A dust removal mechanism is arranged on the other side of the machine tool. The dust removal mechanism includes a fixing member. The fixing member is fixedly installed on the machine tool. A docking pipe is fixedly installed on the fixing member. A swivel joint is rotatably connected to one end of the docking pipe. A conveying pipe is fixedly connected to the other end of the docking pipe. The air inlet end of the vacuum cleaner is connected to the conveying pipe. Avoidance grooves are symmetrically opened on both sides of the feeding plate. A convex shaft is fixedly installed in the avoidance groove. Driving plates are symmetrically arranged on both sides of the lifting frame. A guiding groove for guiding the convex shaft is opened on the driving plate. The guiding groove includes an inclined groove and a vertical groove; The end of the swivel joint just touches the end of the stainless steel pipe. The convex shaft continues to slide along the vertical groove until the pressure roller presses on the stainless steel pipe. During the process of the stainless steel pipe being polished, the vacuum cleaner is started. The vacuum cleaner generates suction on the inside of the stainless steel pipe through the swivel joint, so that the metal dust generated by the internal polishing of the stainless steel pipe enters the vacuum cleaner through the swivel joint, the docking pipe and the conveying pipe, thereby realizing the removal of the metal dust and avoiding the impact on the health of the staff caused by the metal dust.

[0008] Preferably, a vibration mechanism for striking the stainless steel pipe is arranged at one end of the lifting frame, the vibration mechanism comprises a T-shaped rod, an L-shaped rod is arranged at the upper end of the T-shaped rod, one end of the L-shaped rod is connected to the end of the second pulley, a movable sleeve movably plugged into the T-shaped rod, a second spring arranged in the movable sleeve, two sets of sliding sleeves symmetrically arranged on both sides of the movable sleeve, a guide column slidably connected to the sliding sleeve, the upper end of the guide column is fixedly connected to the lifting frame, a third spring sleeved on the guide column, a sliding groove is provided at the upper end of the T-shaped rod, the other end of the L-shaped rod is located in the sliding groove, the upper end of the third spring is fixedly connected to the upper end of the guide column, the lower end of the third spring is fixedly connected to the sliding sleeve, and a roller for striking the stainless steel pipe is rotatably installed at the lower end of the movable sleeve; As the T-bar continues to move back and forth and up and down, the stainless steel pipe will be subjected to continuous impacts. The vibrations generated by the continuous impacts will shake off the metal dust attached to the inner wall of the stainless steel pipe, making the metal dust inside the stainless steel pipe cleaner.

[0009] The beneficial effects of the present invention are as follows: 1. During the grinding process of stainless steel pipes, the staff can take the polished stainless steel pipes off the discharge plate and place the unpolished stainless steel pipes on the empty discharge plate, so that the grinding and placement of stainless steel pipes can be carried out at the same time, saving the time of taking and placing stainless steel pipes and improving the efficiency of grinding processing of stainless steel pipes.

[0010] 2. The lifting frame drives the two sets of driving plates to move downward together. The lower end of the driving plate will first enter the avoidance grooves on both sides of the discharge plate, and then the cam in the avoidance groove will enter the oblique groove on the driving plate. Under the guidance of the oblique groove, the cam drives the discharge plate together with the slider to move toward the dust removal mechanism. At the same time, the slider slides along the slide rod, and the slider compresses the first spring until the cam slides to the intersection of the oblique groove and the vertical groove. At this time, the end of the rotary joint is just attached to the end of the stainless steel pipe, and the cam continues to slide along the vertical groove until the pressure roller presses the stainless steel pipe. During the grinding process of the stainless steel pipe, the vacuum cleaner is started. The vacuum cleaner generates suction to the inside of the stainless steel pipe through the rotary joint, so that the metal dust generated by the grinding inside the stainless steel pipe enters the vacuum cleaner through the rotary joint, the butt joint and the conveying pipe, thereby realizing the removal of metal dust and avoiding the impact of metal dust on the health of the staff.

[0011] 3. The rotating second pulley drives the L-shaped rod to rotate. Through the cooperation with the sliding groove, the L-shaped rod causes the T-shaped rod to move downward and back and forth. When the T-shaped rod moves downward, the lower end of the T-shaped rod presses the second spring, and the rebounding force of the second spring acts on the movable sleeve, causing the movable sleeve to drive the two sets of sliding sleeves to slide downward along the corresponding guide columns and stretching the two sets of third springs until the movable sleeve drives the roller to hit the rotating stainless steel pipe. The impact generates a reaction force acting on the sliding sleeve, further compressing the second spring. At the same time, the impact causes the stainless steel pipe to vibrate. When the T-shaped rod moves upward, under the action of the rebounding forces of the third spring and the second spring, the movable sleeve and the roller move upward. Therefore, as the T-shaped rod continuously moves up and down back and forth, the stainless steel pipe will be continuously impacted, and the vibration generated by the continuous impact shakes off the metal dust adhering to the inner wall of the stainless steel pipe, making the metal dust inside the stainless steel pipe cleaner.

Detailed implementation mode

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes.

[0023] Embodiment 1: As Figure 1 With Figure 2 Shown, a stainless steel part grinding device described in an embodiment of the present invention includes a machine tool 1, two groups of transmission shafts 2 are rotatably installed in the machine tool 1, two groups of sprockets 3 are respectively arranged at both ends of the transmission shaft 2, the two groups of sprockets 3 are respectively engaged with two groups of chains 4, a number of receiving plates 5 are arranged between the two groups of chains 4, a feeding plate 6 is arranged on the receiving plate 5, a driving mechanism 7 for driving the rotation of the stainless steel pipe is arranged on the machine tool 1, a support frame 8 is arranged on one side of the machine tool 1, a movable seat 10 is movably installed on the support frame 8, a push rod 11 is connected to one side of the movable seat 10, a grinding head 12 is arranged at the end of the push rod 11, the driving mechanism 7 includes a support 701, the support 701 is fixedly installed on the machine tool 1, a cylinder 702 for driving the lifting frame 703 is fixedly installed on the support 701, a pressure roller 704 is rotatably installed on the lifting frame 703, a first pulley 705 is installed at the end of the pressure roller 704, a second pulley 706 is rotatably connected to the lifting frame 703, the second pulley 706 and the first pulley 705 are both rotatably connected to a synchronous belt 707, a feeding groove 61 for placing the stainless steel pipe is opened on the feeding plate 6, a number of rollers 62 are rotatably installed in the feeding groove 61, a lead screw 9 is rotatably installed on the support frame 8, the lead screw 9 is screwed to the movable seat 10, the movable seat 10 is slidably connected to the support frame 8, and a guide sleeve 81 for inserting the push rod 11 is fixedly installed on the support frame 8.

[0024] Specifically, attachedFigure 1 The position indicated by the arrow in the figure is the feeding position. A set of feeding plates 6 is at the feeding position. When it is necessary to polish the inner surface of the stainless steel pipe, stainless steel pipes are placed one by one on the multiple sets of feeding plates 6 between the feeding position and the driving mechanism 7. The stainless steel pipe is placed in the feeding groove 61 on a set of feeding plates 6 and is located on a number of sets of rollers 62. By driving a set of transmission shafts 2 to rotate through a motor, the transmission shaft 2 drives two sets of sprockets 3 to rotate. The two sets of sprockets 3 drive two sets of chains 4 together with a number of sets of bearing plates 5 and a number of sets of feeding plates 6 to perform a circular motion, so that the feeding plates 6 drive the stainless steel pipe to move towards the driving mechanism 7 until the stainless steel pipe moves directly below the pressure roller 704. Then, the air cylinder 702 is started, and the air cylinder 702 pushes the lifting frame 703 together with the pressure roller 704 to move downward until the pressure roller 704 presses on the stainless steel pipe. Then, the second pulley 706 is driven to rotate through a motor, and the second pulley 706 drives the first pulley 705 to rotate through the synchronous belt 707. The first pulley 705 drives the pressure roller 704 together with the stainless steel pipe to rotate, and the stainless steel pipe drives a number of sets of rollers 62 in the feeding groove 61 to rotate together. At this time, the lead screw 9 is driven to rotate through a motor, so that the movable seat 10 drives the push rod 11 to slide along the guide sleeve 81. The push rod 11 pushes the grinding head 12 into the stainless steel pipe. The moving grinding head 12 generates friction with the rotating stainless steel pipe to achieve the polishing of the stainless steel pipe. During this process, the operator continues to place the stainless steel pipe on the feeding plate 6 until the stainless steel pipe is polished. Then, the grinding head 12 is withdrawn, and the multiple sets of feeding plates 6 are continuously driven to perform a circular motion to move the next set of stainless steel pipes directly below the pressure roller 704, and the above operations are repeated in a cycle. Compared with the prior art, during the polishing process of the stainless steel pipe, the operator can take the polished stainless steel pipe off the feeding plate 6 and at the same time place the unpolished stainless steel pipe on the empty feeding plate 6, so that the polishing and the taking and placing of the stainless steel pipe can be carried out simultaneously, saving the time for taking and placing the stainless steel pipe and improving the efficiency of polishing and processing the stainless steel pipe.

[0025] As Figures 3 to 5As shown in the figure, the receiving plate 5 includes a plate body 501. Two groups of chains 4 are respectively connected to both ends of the plate body 501. A rectangular groove 502 is opened on the plate body 501. A slide bar 503 is fixedly installed in the rectangular groove 502. A slider 504 is slidably connected to the slide bar 503. The slider 504 is fixedly connected to the blanking plate 6. A first spring 505 is sleeved on the slide bar 503. A dust removal mechanism 13 is arranged on the other side of the machine tool 1. The dust removal mechanism 13 includes a fixing member 131. The fixing member 131 is fixedly installed on the machine tool 1. A docking pipe 132 is fixedly installed on the fixing member 131. A rotary joint 133 is rotatably connected to one end of the docking pipe 132. A conveying pipe 134 is fixedly connected to the other end of the docking pipe 132. The air inlet end of the vacuum cleaner 135 is connected to the conveying pipe 134. Avoidance grooves 63 are symmetrically opened on both sides of the blanking plate 6. A convex shaft 64 is fixedly installed in the avoidance grooves 63. Driving plates 7031 are symmetrically arranged on both sides of the lifting frame 703. Guide grooves 31 for guiding the convex shaft 64 are opened on the driving plates 7031. The guide grooves 31 include an inclined groove 311 and a vertical groove 312.

[0026] Specifically, the inner diameter of the rotary joint 133 is equal to the inner diameter of the stainless steel pipe. During the grinding process of the stainless steel pipe, a large amount of metal dust will be generated. The metal dust will float from inside the stainless steel pipe into the surrounding space, which will affect the health of the staff. When the air cylinder 702 pushes the lifting frame 703 together with the pressure roller 704 to move downward, the lifting frame 703 drives the two driving plates 7031 to move downward together. The lower ends of the driving plates 7031 will first enter the avoidance grooves 63 on both sides of the blanking plate 6. Then, the convex shaft 64 in the avoidance grooves 63 will enter the inclined groove 311 on the driving plate 7031. Under the guidance of the inclined groove 311, the convex shaft 64 drives the blanking plate 6 together with the slider 504 to move towards the dust removal mechanism 13. At the same time, the slider 504 slides along the slide bar 503, and the slider 504 compresses the first spring 505 until the convex shaft 64 slides to the intersection of the inclined groove 311 and the vertical groove 312. At this time, the end of the rotary joint 133 just touches the end of the stainless steel pipe. The convex shaft 64 continues to slide along the vertical groove 312 until the pressure roller 704 presses the stainless steel pipe. During the grinding process of the stainless steel pipe, the vacuum cleaner 135 is started. The vacuum cleaner 135 generates suction on the inside of the stainless steel pipe through the rotary joint 133, so that the metal dust generated by the grinding inside the stainless steel pipe enters the vacuum cleaner 135 through the rotary joint 133, the docking pipe 132, and the conveying pipe 134, thereby realizing the removal of metal dust and avoiding the impact of metal dust on the health of the staff.

[0027] Embodiment 2: As Figures 6 to 8As shown in the figure, compared with the first comparative example, another implementation mode of the present invention is: a vibration mechanism 708 for knocking on the stainless steel pipe is provided at one end of the lifting frame 703. The vibration mechanism 708 includes a T-shaped rod 7071. An L-shaped rod 7072 is provided at the upper end of the T-shaped rod 7071. One end of the L-shaped rod 7072 is connected to the end of the second pulley 706. A movable sleeve 7073 that movably inserts the T-shaped rod 7071, a second spring 7074 provided in the movable sleeve 7073, two groups of sliding sleeves 7075 symmetrically provided on both sides of the movable sleeve 7073, a guide post 7076 slidably connected to the sliding sleeve 7075. The upper end of the guide post 7076 is fixedly connected to the lifting frame 703. A third spring 7077 sleeved on the guide post 7076. A chute 711 is opened at the upper end of the T-shaped rod 7071. The other end of the L-shaped rod 7072 is located in the chute 711. The upper end of the third spring 7077 is fixedly connected to the upper end of the guide post 7076. The lower end of the third spring 7077 is fixedly connected to the sliding sleeve 7075. A roller 731 for hitting the stainless steel pipe is rotatably installed at the lower end of the movable sleeve 7073.

[0028] Specifically, during the process of the dust removal mechanism 13 removing the metal dust inside the stainless steel pipe, the rotating second pulley 706 drives the L-shaped rod 7072 to rotate. The L-shaped rod 7072, through its cooperation with the chute 711, causes the T-shaped rod 7071 to move back and forth downward. When the T-shaped rod 7071 moves downward, the lower end of the T-shaped rod 7071 presses the second spring 7074. The rebounding force of the second spring 7074 acts on the movable sleeve 7073, causing the movable sleeve 7073 to drive the two groups of sliding sleeves 7075 to slide downward along the corresponding guide posts 7076 and stretch the two groups of third springs 7077 until the movable sleeve 7073 drives the roller 731 to hit the rotating stainless steel pipe. The impact generates a reaction force acting on the sliding sleeve 7075, further compressing the second spring 7074. At the same time, the impact causes the stainless steel pipe to vibrate. When the T-shaped rod 7071 moves upward, under the rebounding forces of the third spring 7077 and the second spring 7074, the movable sleeve 7073 and the roller 731 move upward. Therefore, as the T-shaped rod 7071 continuously moves back and forth up and down, the stainless steel pipe will be continuously hit. The vibration generated by the continuous impact shakes off the metal dust adhering to the inner wall of the stainless steel pipe, making the metal dust inside the stainless steel pipe cleaner.

[0029] Working principle: Stainless steel pipes are placed one by one on multiple sets of feeding plates 6 between the feeding position and the driving mechanism 7. The stainless steel pipes are placed in the feeding grooves 61 on a set of feeding plates 6 and are located on several sets of rollers 62. A motor drives a set of transmission shafts 2 to rotate, and the transmission shafts 2 drive two sets of sprockets 3 to rotate. The two sets of sprockets 3 drive two sets of chains 4 together with several sets of receiving plates 5 and several sets of feeding plates 6 to perform circular motion, so that the feeding plates 6 drive the stainless steel pipes to move towards the driving mechanism 7 until the stainless steel pipes move directly below the pressure roller 704. Then, the air cylinder 702 is started, and the air cylinder 702 pushes the lifting frame 703 together with the pressure roller 704 to move downward until the pressure roller 704 presses on the stainless steel pipe. Then, a motor drives the second pulley 706 to rotate, and the second pulley 706 drives the first pulley 705 to rotate through the synchronous belt 707. The first pulley 705 drives the pressure roller 704 together with the stainless steel pipe to rotate, and the stainless steel pipe drives several sets of rollers 62 in the feeding groove 61 to rotate together. At this time, a motor drives the lead screw 9 to rotate, so that the movable seat 10 drives the push rod 11 to slide along the guide sleeve 81, and the push rod 11 pushes the grinding head 12 into the stainless steel pipe. The moving grinding head 12 generates friction with the rotating stainless steel pipe to achieve grinding of the stainless steel pipe. During this process, personnel continue to place stainless steel pipes on the feeding plates 6 until the stainless steel pipes are ground. Then, the grinding head 12 is withdrawn, and several sets of feeding plates 6 are continuously driven to perform circular motion to move the next set of stainless steel pipes directly below the pressure roller 704, and the above operations are repeated in a cycle; When the air cylinder 702 pushes the lifting frame 703 together with the pressure roller 704 to move downward, the lifting frame 703 drives two sets of driving plates 7031 to move downward together. The lower ends of the driving plates 7031 will first enter the avoidance grooves 63 on both sides of the feeding plate 6. Then, the convex shafts 64 in the avoidance grooves 63 will enter the inclined grooves 311 on the driving plates 7031. Under the guidance of the inclined grooves 311, the convex shafts 64 drive the feeding plate 6 together with the slider 504 to move towards the dust removal mechanism 13. At the same time, the slider 504 slides along the slide rod 503, and the slider 504 compresses the first spring 505 until the convex shaft 64 slides to the intersection of the inclined groove 311 and the vertical groove 312. At this time, the end of the rotary joint 133 just touches the end of the stainless steel pipe. The convex shaft 64 continues to slide along the vertical groove 312 until the pressure roller 704 presses on the stainless steel pipe. During the grinding of the stainless steel pipe, the vacuum cleaner 135 is started. The vacuum cleaner 135 generates suction on the inside of the stainless steel pipe through the rotary joint 133, so that the metal dust generated by the internal grinding of the stainless steel pipe enters the vacuum cleaner 135 through the rotary joint 133, the docking pipe 132, and the conveying pipe 134, thereby realizing the removal of metal dust; During the process of the dust removal mechanism 13 removing the metal dust inside the stainless steel pipe, the rotating second pulley 706 drives the L-shaped rod 7072 to rotate. The L-shaped rod 7072, through its cooperation with the chute 711, causes the T-shaped rod 7071 to move back and forth downward. When the T-shaped rod 7071 moves downward, the lower end of the T-shaped rod 7071 presses the second spring 7074. The rebounding force of the second spring 7074 acts on the movable sleeve 7073, causing the movable sleeve 7073 to drive the two sets of sliding sleeves 7075 to slide downward along the corresponding guide posts 7076, and stretching the two sets of third springs 7077 until the movable sleeve 7073 drives the roller 731 to impact the rotating stainless steel pipe. The impact generates a reaction force acting on the sliding sleeve 7075, causing the second spring 7074 to be further compressed. At the same time, the impact causes the stainless steel pipe to vibrate. When the T-shaped rod 7071 moves upward, under the action of the rebounding forces of the third spring 7077 and the second spring 7074, the movable sleeve 7073 and the roller 731 move upward. Therefore, as the T-shaped rod 7071 continuously moves back and forth up and down, the stainless steel pipe will be continuously impacted. The vibration generated by the continuous impact causes the metal dust adhering to the inner wall of the stainless steel pipe to be shaken off.
