Description

Technical Field

[0001] The invention relates to the technical field of pump body spherical surface processing, in particular to a spherical surface processing device and a processing method for an axial flow pump runner chamber. Background Art

[0002] Axial mixed flow pump is an important branch of the vane pump category. Its most critical core component is called hydraulic component, which is composed of impeller and guide vane. It uses the rotating axial force and atmospheric pressure to pressurize and energize the liquid and transport it out.

[0003] The impeller chamber of the axial mixed flow pump needs to be processed by cutting when processing the inner spherical surface. Since a lot of waste chips will be generated when cutting the inner spherical surface, the existing devices generally clean the waste chips during cutting by manual cleaning. During manual cleaning, workers need to stop the cutting operation and use tools such as "brushes" to clean the waste chips from the workpiece and the tool.

[0016] Furthermore, a method for using a spherical surface processing device in an axial flow pump runner chamber, and a spherical surface processing device in an axial flow pump runner chamber, the method comprises the following steps:

[0017] S1: First, the staff manually opens the clamping blocks on the chuck and places the workpiece to be cut between the multiple clamping blocks so that the chuck can clamp the workpiece. Then, the chuck is pushed to slide on the slide rail. When the sliding of the chuck makes the center line of the workpiece in the middle of the tool holder;

[0018] S2: The chuck can be firmly stopped on the slide rail by turning the bolts on the side wall of the chuck. Then the motor is started. When the motor rotates, it drives the tool holder to rotate. When the tool holder rotates, the inside of the workpiece is cut. At the same time, the staff can rotate the worm.

[0019] S3: When the worm is rotating, it will drive the transmission frame to rotate. When the transmission frame rotates, it will drive the connecting strip to move through the sliding ring. When the connecting strip moves, it will push the tool holder, so that the tool holder drives the cutting tool to rotate, so as to complete the cutting of the inner spherical surface of the workpiece.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the rotation of the motor drives the spring rod to rotate, the rotation of the spring rod will drive a plurality of fan plates and the grille ring to rotate synchronously. When the plurality of fan plates are rotating, the rotation of the fan plates will absorb the external gas into the outer cylinder through the rectangular grooves on the outer cylinder. When the gas enters the outer cylinder, the rotation of the fan plates will blow the gas toward the grille ring. At this time, the gas will be guided by the conical plate to enter the interior of the grille ring. After that, when the grille ring rotates rapidly, the rotation of the grille ring will cause the gas entering the middle of the grille ring to generate an outward swinging force. At this time, the swung gas will enter through the hose. The gas is ejected into the curved jet pipe and ejected through the curved jet pipe. Since the curved jet pipe is curved, the ejected gas will form a spiral flow to flow into the inside of the workpiece when the gas is ejected. At this time, the wind force of the spiral ejection can blow away the waste chips generated by cutting from the processing area in time, reducing downtime for cleaning, and avoiding the accumulation of waste chips in the workpiece. At the same time, it can also reduce the scratches on the processed surface by waste chips, making the inner spherical surface smoother after processing, improving the quality of the processed surface, and helping to improve the processing accuracy and reduce the processing error caused by waste chips.

[0022] 2. In the present invention, when the motor drives the spring rod to rotate, the rotation of the spring rod drives the fixed plate to rotate synchronously. When the fixed plate rotates, the insertion rod on the telescopic frame will be inside the annular wave groove opened on the side wall of the fixed plate, and rotate up and down with the rotation of the annular groove. When the insertion rod drives the telescopic frame to move upward, it will drive the elastic shaft to form an outward bulging deformation in the middle part. Since the fixed ring can only rotate but not move on the surface of the spring rod, the elastic shaft will pull the sliding cylinder to move in the direction of the fixed ring when it is deformed. When the sliding cylinder moves, it will push the curved jet tube through the movable frame. When the movable frame pushes the curved jet tube, the curved jet tube will cause the curved jet tube to rotate outward. At this time, the rotation of multiple curved jet tubes will rotate and expand outward, and then When the telescopic frame moves downward, the downward pressure of the fixed plate on the elastic shaft and the resilience of the elastic shaft itself will cause the sliding ring 2 to reset. When the sliding ring 2 is reset, it will pull the curved jet tube through the movable frame to reset and shrink inward, thus forming a reciprocating contraction and expansion movement. The reciprocating swing of expansion and contraction of the curved jet tube can make the ejected gas blow up and down on the basis of spiral ejection, which can effectively expand the coverage of the gas inside the workpiece, especially for the transition area between the uncut part and the cut part, so as to better clean the waste chips. Moreover, this dynamic jet can reach more corners and gaps, making the waste chip cleaning more comprehensive and reducing the cleaning dead corners, thereby improving the uniformity of the jet and enhancing the cleaning effect of the waste chips.

[0023] 3. According to the present invention, when it is necessary to cut the workpiece, the spring rod is connected to the output end of the motor by a bolt, and then when the chuck is pushed, the side wall of the chuck will squeeze the side wall of the outer cylinder. At this time, the suction cup on the outer cylinder will adsorb the side wall of the chuck, and the outer cylinder will not rotate with the spring rod. When the output end of the motor drives the spring rod to rotate, the outer cylinder will drive the semicircular plate to move backward on the surface of the spring rod after being squeezed by the chuck. When the semicircular plate moves backward, it will push the connecting rod. At this time, the reaction force generated by the connecting rod being pushed by the semicircular plate will push the semicircular plate, so that the semicircular plate rotates outward on the surface of the outer cylinder. When the semicircular plate rotates, it will drive the multi-shaped block to rotate synchronously. When the multi-shaped block rotates, it will make the elastic roller contact with the inner wall of the workpiece. Then, when the semicircular plate continues to rotate, the rotation of the semicircular plate will drive the multi-shaped block to rotate synchronously. When the multi-shaped block rotates, it will drive the hollow plate to rotate upward through the L plate. When the hollow plate rotates upward, the top of the hollow plate will squeeze the inner wall of the workpiece. At this time, the rotating plate on the hollow plate will be squeezed by the inner wall of the workpiece and rotate inside the hollow plate. When the rotating plate rotates, the rotating plate will squeeze the middle plate and make the middle plate push the spring block to move upward inside the fixed frame. When the spring block moves upward, it will squeeze the gas inside the fixed frame. After being squeezed, the gas will enter the inside of the knife airbag and expand and come into close contact with the inner wall of the workpiece. When the airbag is in close contact with the inner wall of the workpiece, a flexible supporting structure can be formed around the tool holder, which can withstand and disperse the lateral force exerted on the cutting tool during cutting and play a buffering role, which can reduce the vibration amplitude generated by the cutting tool when it is subjected to lateral force during cutting, avoid the vibration of the cutting tool from causing excessive interference to the entire processing process, enable the cutting tool to cut more stably, and enhance the accuracy of the cutting path of the cutting tool.

[0049] A method for using a spherical surface processing device in an axial flow pump runner chamber, the spherical surface processing device in an axial flow pump runner chamber, the method comprising the following steps:

[0050] S1: First, a staff member manually opens the clamping blocks on the chuck 106 and places the workpiece to be cut between the multiple clamping blocks, so that the chuck 106 can clamp the workpiece, and then pushes the chuck 106 to slide on the slide rail. When the sliding of the chuck 106 makes the center line of the workpiece in the middle of the tool holder 203;

[0051] S2: The chuck 106 can be firmly stopped on the slide rail by rotating the bolts on the side wall of the chuck 106, and then the motor 101 is started. When the motor 101 rotates, it drives the tool holder 203 to rotate. When the tool holder 203 rotates, the inside of the workpiece is cut. At the same time, the staff can rotate the worm 105;

[0052] S3: When the worm 105 rotates, it drives the transmission frame 103 to rotate. When the transmission frame 103 rotates, it drives the connecting bar 202 to move through the sliding ring 201. When the connecting bar 202 moves, it pushes the tool holder 203, so that the tool holder 203 drives the cutting tool 204 to rotate, thereby completing the cutting of the inner spherical surface in the workpiece.

[0053] When in use, the staff first manually opens the clamping blocks on the chuck 106 and places the workpiece to be cut between the multiple clamping blocks, so that the chuck 106 can clamp the workpiece, and then pushes the chuck 106 to slide on the slide rail. When the sliding of the chuck 106 makes the center line of the workpiece in the middle of the tool holder 203, the chuck 106 can be firmly stopped on the slide rail by rotating the bolts on the side wall of the chuck 106. Then, the motor 101 is started. When the motor 101 rotates, it will drive the tool holder 203 to rotate. When the tool holder 203 rotates, it will cut the inside of the workpiece. At the same time, the staff can rotate the rotating worm 105. When the rotating worm 105 rotates, it will drive the transmission frame 103 to rotate. When the transmission frame 103 rotates, it will drive the connecting strip 202 to move through the sliding ring 201. When the connecting strip 202 moves, it will push the tool holder 203, so that the tool holder 203 drives the cutting tool 204 to rotate, so as to complete the cutting of the inner spherical surface in the workpiece.

[0054] When it is necessary to cut the workpiece, the spring rod 301 is connected to the output end of the motor 101 by a bolt, and then when the chuck 106 is pushed, the side wall of the chuck 106 will squeeze the side wall of the outer cylinder 304. At this time, the suction cup on the outer cylinder 304 will adsorb the side wall of the chuck 106. At this time, the outer cylinder 304 will not rotate with the spring rod 301. When the output end of the motor 101 drives the spring rod 301 to rotate, the outer cylinder 304 is squeezed by the chuck 106 and drives the semicircular plate 402 to move backward on the surface of the spring rod 301. When the plate 402 moves backward, it pushes the connecting rod 401. At this time, the reaction force generated by the push of the semicircular plate 402 on the connecting rod 401 will push the semicircular plate 402, so that the semicircular plate 402 rotates outward on the surface of the outer cylinder 304. When the semicircular plate 402 rotates, it will drive the multi-shaped block 403 to rotate synchronously. When the multi-shaped block 403 rotates, the elastic roller will contact the inner wall of the workpiece. Then, when the semicircular plate 402 continues to rotate, the rotation of the semicircular plate 402 will drive the multi-shaped block 403 to rotate synchronously. When the multi-shaped block 403 rotates, it will pass through the L plate 404 drives the hollow plate 501 to rotate upward. When the hollow plate 501 rotates upward, the top of the hollow plate 501 will squeeze the inner wall of the workpiece. At this time, the rotating plate 502 on the hollow plate 501 will be squeezed by the inner wall of the workpiece and rotate inside the hollow plate 501. When the rotating plate 502 rotates, the rotating plate 502 will squeeze the middle plate 503 and make the middle plate 503 push the spring block 505 to move upward inside the fixed frame 504. When the spring block 505 moves upward, it will squeeze the gas inside the fixed frame 504, and the gas will enter the airbag after being squeezed. The airbag is inserted into the interior of the workpiece and expands so as to make close contact with the inner wall of the workpiece. When the airbag is in close contact with the inner wall of the workpiece, a flexible support structure can be formed around the tool holder 203, which can withstand and disperse the lateral force exerted on the cutting tool 204 during cutting and play a buffering role, thereby reducing the vibration amplitude generated by the lateral force exerted on the cutting tool 204 during cutting, avoiding the vibration of the cutting tool 204 from causing excessive interference to the entire machining process, enabling the cutting tool 204 to cut more stably, and enhancing the accuracy of the cutting path of the cutting tool 204.

[0055] When the rotation of the motor 101 drives the spring rod 301 to rotate, the rotation of the spring rod 301 will drive the plurality of fan plates 302 and the grille ring 303 to rotate synchronously. When the plurality of fan plates 302 are rotating, the rotation of the fan plates 302 will absorb the external gas into the outer cylinder 304 through the rectangular groove on the outer cylinder 304. When the gas enters the outer cylinder 304, the rotation of the fan plates 302 will blow the gas toward the grille ring 303. At this time, the gas will be guided by the conical plate 305 to enter the interior of the grille ring 303. Then, when the grille ring 303 rotates rapidly, the rotation of the grille ring 303 will cause the gas entering the middle of the grille ring 303 to generate an outward swinging force. At this time, the swung gas will enter the curved air jet pipe 601 through the hose 602 and be ejected through the curved air jet pipe 601. Since the curved air jet pipe 601 is curved, the ejected gas will form a spiral flow to flow into the inside of the workpiece when the gas is ejected. At this time, the spiral wind force can blow away the waste chips generated by cutting from the processing area in time, reducing downtime for cleaning, and avoiding the accumulation of waste chips in the workpiece. At the same time, it can also reduce the scratches on the processed surface by waste chips, making the processed inner spherical surface smoother, improving the quality of the processed surface, and helping to improve the processing accuracy and reduce the processing errors caused by waste chips.

[0056] When the motor 101 drives the spring rod 301 to rotate, the rotation of the spring rod 301 drives the fixed plate 705 to rotate synchronously. When the fixed plate 705 rotates, the insertion rod on the telescopic frame 704 will be inside the annular wave groove opened on the side wall of the fixed plate 705, and rotate up and down with the rotation of the annular groove. When the insertion rod drives the telescopic frame 704 to move upward, it will drive the elastic shaft 702 to form an outward bulging deformation in the middle part. Since the fixed ring 703 can only rotate but not move on the surface of the spring rod 301, the elastic shaft 702 will pull the sliding cylinder 701 to move in the direction of the fixed ring 703 when it is deformed. When the sliding cylinder 701 moves, it will push the curved jet tube 601 through the movable frame 604. When the movable frame 604 pushes the curved jet tube 601, the curved jet tube 601 will cause the curved jet tube 601 to rotate outward. At this time, multiple curved jet tubes 601 The rotation of the curved jet tube 601 can make the gas ejected from the workpiece to blow up and down on the basis of the spiral ejection, which can effectively expand the coverage of the gas inside the workpiece, especially for the transition area between the uncut part and the cut part, so that the waste chips can be better cleaned, and this dynamic jet can reach more corners and gaps, making the waste chip cleaning more comprehensive and reducing the cleaning dead angles, thereby improving the uniformity of the jet and enhancing the cleaning effect of the waste chips.
