[0015] The beneficial effects of the present utility model are as follows: As a pump housing processing system that can continuously process without replacing the tool bit, adapt to various cutting angles at the same time, and effectively solve the milling of the inner cavity of the rotary body of the pump housing, the specific implementation manners are as follows:

[0016] The operator first places the pump housing between the support columns. After that, the fixed latching plates on the support columns are rotated in sequence to abut against the outer wall of the pump housing. Then, the rotating nut is tightened on the support threaded rod to fix the fixed latching plate, so as to fix the pump housing and facilitate subsequent processing.

[0017] After that, the first connecting frame and the second connecting frame are rotated. After placing the main rotating pipe, the variable-diameter movable rod and the adjusting sleeve at the center of the middle rotary body of the pump housing, they are supported by the bracket composed of the second buckling bracket and the first buckling bracket. After completion, the implementation operation can be started.

[0018] Start the rotating motor, which drives the main rotating tube to rotate. At this time, the adjusting motor stops rotating. Since the connecting ball on the adjusting motor is connected to the main rotating tube through the ball-type buckle block, even if the main rotating tube rotates, the adjusting motor will not cause motion interference. During the rotation of the main rotating tube, the rotating disk on the sliding cutter rod can be used to cut the rotating body in the inner cavity of the pump casing. At the same time, due to the different actual functions of the pump, the rotating body in the pump is usually connected by multiple groups of circular cavities with different radii. In order to avoid replacing the cutting knife many times, during the rotation of the main rotating tube, start the pitch adjusting motor, which drives the rotating adjusting screw rod to change the spacing between the movable block and the fixed block bracket through the cooperation of the single fixed groove slider on the sliding fixed groove, thereby further driving the change of the adjustment The distance between the motor and the rotating motor, at the same time, since the adjustment motor is connected to the main rotating tube and the rotating motor is connected to the adjusting sleeve, the change in the distance drives the variable diameter movable rod to slide in the center of the main rotating tube. During the sliding of the variable diameter movable rod, the extension pull rod drives the pull lever to slide in the inclined slide groove. Since the sliding tool rod is slidably connected to the main rotating tube, the sliding tool rod can be extended or retracted to change the rotation radius of the die cutting tool on the main rotating tube during the rotation process, that is, to achieve the replacement of the cutting radius without stopping the machine; then start the moving motor to drive the moving threaded rod to rotate, so as to realize the lateral movement of the moving cross block, drive the processing mechanism to move horizontally as a whole, and cooperate with the tool head that can change the radius during rotation to realize the cutting function of the continuous rotating body;

[0019] Since the rotating body cavity in the middle of the pump casing is usually chamfered, the relatively fixed die-cutting knife cannot cope with the cutting work of the rotating body edge, and there will be some positions that cannot be penetrated or contacted by the sliding knife rod. At this time, the adjustment motor is started, and the adjustment motor drives the rotating disk to rotate, and at the same time drives the support ring to rotate. Since the adjustment sleeve is slidably connected to the main rotating tube, the adjustment sleeve rotates in the same direction during the rotation of the main rotating tube, and at the same time drives the bearing connecting ring to rotate. The bearing connecting ring and the bearing outer ring form a bearing through the bearing rod. During the rotation of the support ring, since the positions of the support ring, the rotating disk and the limit disk are relatively fixed, the rotation of the support ring promotes the activity The outer ring of the connecting block clamping bearing moves in the guiding direction of the limit lever, further driving the adjusting sleeve to slide on the main rotating tube. During the sliding process of the adjusting sleeve, the adjusting sleeve pushes the transverse pull rod to move the transverse moving rod. At the same time, the transverse moving rod drives the knife lever to slide in the knife moving groove of the die cutting knife. Due to the fixing effect of the knife rotating shaft in the die cutting knife, the die cutting knife tilts, thereby realizing the tilting effect of the knife head and coping with different cutting positions. At the same time, the auxiliary cross bar on the auxiliary rod protrusion and the transverse sliding groove on the transverse pull rod are mainly to ensure that the adjusting effect of the adjusting sleeve on the die cutting knife will not be affected during the movement of the sliding knife rod.

[0020] The device has a simple structure. By utilizing the relative positions of the main rotating tube, the variable-diameter movable rod, and the adjusting sleeve, the length of the sliding cutter bar and the angle of the profiling cutter are changed during rotation, effectively solving the problem that the pump shell with a rotary inner cavity having an arc-shaped edge can be machined without replacing the cutter head, which has good practicability and economy and is beneficial to the popularization and use of the device.

One ends of the second buckling bracket 331 and the first buckling bracket 322 are in contact with and slidably connected to the outer periphery of the middle part of the buckling sliding cross bar 37.

[0043] The working principle of the present utility model:

[0044] The operator first places the pump casing between the support columns 14. After sequentially rotating the fixed lapping plates 16 on the support columns 14 to abut against the outer wall of the pump casing, and then screwing the rotating nut 151 to tighten the support threaded rod 15 to fix the fixed lapping plate 16, the fixation of the pump casing can be realized, which is convenient for subsequent processing.

[0045] After that, rotate the first connecting frame 33 and the second connecting frame 321. After placing the main rotating pipe 21, the variable-diameter movable rod 22 and the adjusting sleeve 23 at the center of the middle rotating body of the pump casing, they are supported by the bracket composed of the second buckling bracket 331 and the first buckling bracket 322. After completion, the implementation operation can be started.

[0046] Start the rotating motor 221. The rotating motor 221 drives the main rotating pipe 21 to rotate. At this time, the adjusting motor 25 stops rotating. Since the connecting ball 251 on the adjusting motor 25 is connected to the main rotating pipe 21 through the spherical snap block 13, even if the main rotating pipe 21 rotates, the adjusting motor 25 will not generate movement interference. During the rotation of the main rotating pipe 21, the rotating disk 252 on the sliding tool bar 24 can cut the rotating body in the inner cavity of the pump housing. At the same time, due to the different actual use functions of the pump, the rotating bodies in the pump usually adopt multiple groups of circular cavities with different radii connected. To avoid replacing the cutting tool multiple times, during the rotation of the main rotating pipe 21, start the distance adjusting motor 34. The distance adjusting motor 34 drives the rotating adjusting screw rod 341 to change the distance between the movable block 31 and the fixed block 32 bracket through the cooperation of the single fixed groove slider 353 on the sliding fixed groove 352, further driving the change of the distance between the adjusting motor 25 and the rotating motor 221. At the same time, since the adjusting motor 25 is connected to the main rotating pipe 21 and the rotating motor 221 is connected to the adjusting sleeve 23, the change of the distance between them drives the variable diameter movable rod 22 to slide in the center of the main rotating pipe 21. During the sliding of the variable diameter movable rod 22, the extension pull rod 224 drives the pulling lever 223 to slide in the inclined sliding groove 241. Since the sliding tool bar 24 is slidably connected to the main rotating pipe 21, the sliding tool bar 24 can extend or retract, changing the rotation radius of the cutting tool 242 relative to the main rotating pipe 21 during rotation, that is, realizing the replacement of the cutting radius without stopping the machine; After that, start the moving motor 361 to drive the moving threaded rod 351 to rotate, and the transverse movement of the moving cross block 35 can be realized, driving the whole processing mechanism 2 to move transversely, and cooperating with the tool head whose radius can be changed during rotation to realize the cutting function of the continuous rotating body;

[0047] Since the rotating body cavity in the middle of the pump casing is usually chamfered, the relatively fixed die-cutting knife 242 cannot cope with the cutting work of the edge of the rotating body, and there will be some positions that cannot be penetrated or contacted by the sliding knife rod 24. At this time, the adjustment motor 25 is started, and the adjustment motor 25 drives the rotating disk 252 to rotate, and at the same time drives the supporting ring 26 to rotate. Since the adjusting sleeve 23 is slidably connected to the main rotating tube 21, the adjusting sleeve 23 rotates in the same direction during the rotation of the main rotating tube 21, and at the same time drives the bearing connecting ring 281 to rotate. The bearing connecting ring 281 and the bearing outer ring 28 form a bearing through the bearing rod 282. During the rotation of the supporting ring 26, since the positions of the supporting ring 26, the rotating disk 252 and the limiting disk 27 are relatively fixed, the rotation of the supporting ring 26 pushes the movable connecting block 285 to clamp the bearing The outer ring 28 moves in the guide direction of the limit lever 271, further driving the adjusting sleeve 23 to slide on the main rotating tube 21. During the sliding process of the adjusting sleeve 23, the adjusting sleeve 23 pushes the lateral pull rod 231 to move the lateral moving rod 246. At the same time, the lateral moving rod 246 drives the knife lever 247 to slide in the knife movable groove 2421 of the die cutting knife 242. Due to the fixing effect of the knife rotating shaft 243 in the die cutting knife 242, the die cutting knife 242 is tilted, which can realize the tilting effect of the knife head and achieve different cutting positions. At the same time, the auxiliary cross bar 2441 on the auxiliary rod protrusion 244 and the lateral sliding groove 232 on the lateral pull rod 231 are mainly used to ensure that the adjusting effect of the adjusting sleeve 23 on the die cutting knife 242 will not be affected during the movement of the sliding knife rod 24.
