Description

Technical Field

[0001] The present invention relates to the technical field of self-priming pump component processing, and in particular to a self-priming pump component turning and forming processing device and method. Background Art

[0002] A self-priming centrifugal pump is characterized by its compact structure, convenient operation, smooth operation, easy maintenance, high efficiency, long life, and strong self-priming ability. The pump cover is a key component of the pump and is crucial to its sealing performance. It ensures stable pressure within the pump and prevents liquid leakage. The pump cover also connects the pump body and pump bearings, providing support for the pump's interior and ensuring the pump remains stable during normal operation.

[0003] After the self-priming pump cover is cast, in order to consider the sealing and installation dimensional accuracy, it is generally necessary to grind the sealing surfaces at both ends. Because the shape of the self-priming pump cover is irregular, the clamping end commonly used on the processing machine tool is difficult to effectively lock the self-priming pump cover. In this case, it is not suitable to process the self-priming pump cover by the processing machine tool, so manual processing is often used to grind the sealing surfaces at both ends of the self-priming pump cover. However, the manual processing method, on the one hand, is difficult to ensure the accuracy and consistency of the grinding process, so the grinding effect is not ideal; on the other hand, the processing process is relatively slow, and the efficiency of batch processing of self-priming pump covers is low, which in turn affects the factory efficiency of the self-priming pump cover and the subsequent assembly progress of the self-priming pump.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0030] See Figure 1 A self-priming pump component turning and forming processing device includes a turning tool 1 mounted on a lathe tool post, a lathe chuck 5 mounted on the lathe spindle box, and a tail cone 2 mounted on the lathe tailstock. A locking mechanism 3 for locking the self-priming pump cover is provided between the lathe chuck 5 and the tail cone 2. It should be noted that the lathe in the present invention is an existing common grinding machine tool. Its included spindle box, tailstock, tool holder and other structures are not shown in the drawings. The lathe chuck 5 is a common multi-jaw chuck.

[0031] See Figure 1 、 Figure 4 and Figure 6 The locking mechanism 3 includes a circular main seat 4 arranged between the lathe chuck 5 and the tail cone 2, and an end locking assembly 32 for locking the end of the self-priming pump cover is provided inside the circular main seat 4, and a pipe locking assembly 31 for locking the pipe of the self-priming pump cover is symmetrically provided on the side of the circular main seat 4 close to the tail cone 2 corresponding to the position of the end of the pipe of the self-priming pump cover. The center of the circular main seat 4 close to the tail cone 2 is fixedly connected with a top column 21, and a centering hole 22 is provided at the outer end of the top column 21. The pointed head of the tail cone 2 cooperates with the centering hole 22. The side of the circular main seat 4 close to the lathe chuck 5 is fixedly connected with a cone frame 41, and the end of the cone frame 41 close to the lathe chuck 5 is fixedly connected with a round head 42, and the round head 42 is clamped and fixed by the lathe chuck 5.

[0032] During specific work, the top column 21 and the tail cone 2 cooperate to achieve the effect of centering locking and supporting, and the processing device is installed as a whole on the lathe chuck 5 through the round head 42; through the use of the locking mechanism 3, the irregular self-priming pump cover can be firmly installed on the lathe, so that the alternating turning processing of the two surfaces of the self-priming pump cover can be carried out stably later.

[0033] See Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The pipe locking assembly 31 includes a fixed block 3110 symmetrically fixedly connected to a non-center position on one side of the circular main seat 4 near the tail cone 2. A plurality of electric push rods 319 are fixedly connected to the fixed block 3110. The output ends of the electric push rods 319 on the same fixed block 3110 are all facing the pump cover of the self-priming pump and are fixedly connected to a fixed seat 318. A mounting disc 314 is fixedly connected to the fixed seat 318. A side wall of the mounting disc 314 near the pump cover of the self-priming pump is provided with a plurality of guide grooves 3141 distributed equidistantly around the circumference. The guide grooves 3141 extend radially along the mounting disc 314. There is a supporting column 317 slidingly connected inside, and the mounting disc 314 is rotatably connected to the center of the side wall of the self-priming pump cover with a rotating rod 312. One end of the rotating rod 312 extends to the inside of the mounting disc 314 and is fixedly connected to a circular plate 315. The circular plate 315 is provided with an oblique groove 316 at the position corresponding to each supporting column 317. The oblique groove 316 extends obliquely from the edge of the circular plate 315 toward its center. The inner end of the supporting column 317 passes through the oblique groove 316 and is slidably connected to the oblique groove 316. The other end of the rotating rod 312 extends to the outside of the mounting disc 314 and is provided with a control component 311 for controlling its rotation.

[0034] See Figure 5The control component 311 includes a gear 3111 fixedly connected to one end of a rotating rod 312 located outside the mounting disk 314, and a rack 3112 is meshedly connected to one side of the gear 3111. The rack 3112 is fixedly connected to the output end of an electric push rod 3113, and the electric push rod 3113 is fixedly connected to the outer wall of the mounting disk 314.

[0035] During specific operation, after the self-priming pump cover is installed, the electric push rod 2 319 is used to control the movement of the fixed seat 318 to drive the installation disc 314 to approach the pipe, so that the support column 1 317 can be inserted into the pipe, and then the electric push rod 1 3113 is used to control the movement of the rack 3112 to drive the gear 1 3111 to rotate, and the gear 1 3111 controls the rotation of the rotating rod 1 312 to drive the circular plate 1 315 to rotate, so that the oblique groove 316 on the circular plate 1 315 synchronously controls the corresponding support column 1 317 to move along the guide groove 1 3141 away from the center of the installation disc 314, so that each support column 1 317 is synchronously pressed against the inner wall of the pipe to achieve the locking effect of the pipe. When the grinding surface of the self-priming pump cover is replaced, it is necessary to first release the fixation of the self-priming pump cover and then turn it over. After turning it over, the position of the pipe will also change accordingly. At this time, the pipe will cooperate with another pipe locking assembly 31 to ensure that the pipes of the self-priming pump cover are effectively locked and fixed during the period when the sealing surfaces at both ends of the self-priming pump cover are processed.

[0036] See Figure 2 The inner end of the first support post 317 passes through the oblique groove 316 and is fixedly connected to the limit plate 313. The diameter of the limit plate 313 is larger than that of the first support post 317. In actual operation, the limit plate 313 can limit the first support post 317, preventing the first support post 317 from moving horizontally along the guide groove 3141 and thus escaping from the guide groove 3141.

[0037] See Figure 1 and Figure 7 A positioning support block 45 is provided on the side of the circular main seat 4 near the tail cone 2, corresponding to the fixed block 3110. This support block 45 is used to align the center of the butt joint tube with the corresponding mounting disc 314. During operation, the center hole of the self-priming pump cover is passed through the top column 21, and then the cover is rotated to place the butt joint tube on the top of the positioning support block 45. At this point, the butt joint tube and the central axis of the corresponding mounting disc 314 are aligned. This prevents reciprocating adjustment of the butt joint tube position and prevents alignment deviation between the butt joint tube and the mounting disc 314, which could directly affect the subsequent internal clamping limit of the butt joint tube.

[0038] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5The end locking assembly 32 includes a second guide groove 327 which is equidistantly arranged on the side wall of the circular main seat 4 close to the tail cone 2. The second guide groove 327 extends radially along the circular main seat 4 and is connected to the interior of the circular main seat 4. A second column 323 is slidably connected in the second guide groove 327. One end of the second column 323 located inside the circular main seat 4 is fixedly connected to an engaging block 324. A second rotating rod 326 is rotatably connected to the center of the inner wall of one side of the circular main seat 4 close to the lathe chuck 5. A second circular plate 322 is fixedly connected to the second rotating rod 326. A vortex rail 325 is fixedly connected to the side of the circular plate 322 close to the engaging block 324. All the engaging blocks 324 are engaged with the vortex rail 325 together. The second circular plate 322 is provided with a control component 321 for controlling its rotation.

[0039] See Figure 3 The second control component 321 includes a gear ring 3214 fixedly connected to the periphery of the second circular plate 322, and one side of the gear ring 3214 is meshedly connected to the second gear 3211, and the second gear 3211 is rotatably connected to the inner wall of the circular main seat 4.

[0040] During specific operation, first make the center hole of the self-priming pump cover pass through the top column 21 and make the self-priming pump cover close to the side wall of the circular main seat 4, then rotate the gear 2 3211 to drive the ring gear 3214 to rotate, and the ring gear 3214 controls the rotation of the circular plate 2 322, so that the vortex rail 325 controls each meshing block 324 to drive the second column 323 to move synchronously, and at the same time, under the limitation of the guide groove 2 327, the second column 323 moves radially along the circular main seat 4, and the second column 323 is used to support the end of the self-priming pump cover internally or externally.

[0041] See Figure 1 、 Figure 4 and Figure 5 The end of the second support column 323 located outside the circular main seat 4 is provided with a symmetrically distributed bayonet 3231 for clamping and limiting the end of the self-priming pump cover. Figure 1 As shown, the end edge of the self-priming pump cover protrudes from the edge of the self-priming pump cover body to form a circular ring structure. The provided bayonet 3231 can not only realize the circumferential clamping of the end of the self-priming pump cover, but also implement axial limitation of the self-priming pump cover by engaging with the end edge, ensuring that the self-priming pump cover is stably fixed on the circular main seat 4, thereby improving the grinding quality of the self-priming pump cover.

[0042] See Figure 3 、 Figure 4 and Figure 5The center of gear 2 3211 is splined to a mounting post 3213, which is threaded between the inner walls of the circular main seat 4. One end of the mounting post 3213 extends through a side wall of the circular main seat 4 near the tail cone 2 and defines a hexagonal slot 3212. During operation, mounting post 3213 is manually rotated using a hexagonal screwdriver (or an existing hexagonal post that fits within slot 3212). This drives gear 2 3211, which is then locked using the threaded connection between mounting post 3213 and the circular main seat 4.

[0043] See Figure 1 and Figure 7 The positioning support block 45 is inserted with a positioning pin. A plurality of pin holes are provided on the side of the circular main seat 4 near the tail cone 2, corresponding to the positioning pins. The positioning pins engage with the corresponding pin holes. When the inner diameter of the pipe changes, the position of the positioning support block 45 changes synchronously, allowing the positioning support block 45 to support and align the pipe.

[0044] When in use: S1: First, turn a cover, first position the self-priming pump cover according to the required turning surface, when positioning, pass the center hole of the self-priming pump cover through the top column 21, then rotate the self-priming pump cover, use the positioning support block 45 to align the connecting pipe with the central axis of the corresponding mounting disc 314 at one time, then, control the fixing seat 318 to move and drive the mounting disc 314 to approach the connecting pipe through the electric push rod 2 319, so that the support column 1 317 can be inserted into the connecting pipe.

[0045] S2: After the support column 317 is aligned with the connecting pipe, the electric push rod 3113 controls the rack 3112 to move and drive the gear 3111 to rotate. The gear 3111 controls the rotating rod 312 to rotate and drive the circular plate 315 to rotate, so that the inclined grooves 316 of the circular plate 315 synchronously control the support columns 317 to move along the guide groove 3141 away from the center of the mounting disk 314, so that the support columns 317 synchronously press against the inner wall of the connecting pipe, thereby locking the connecting pipe.

[0046] S3: Use a hexagonal screwdriver (or an existing hexagonal column that can be matched with the hexagonal slot 3212) to cooperate with the hexagonal slot 3212 to manually rotate the installation column 3213, and drive the gear 2 3211 to rotate through the installation column 3213 to drive the ring gear 3214 to rotate. The ring gear 3214 controls the rotation of the circular plate 2 322, so that the vortex track 325 of the circular plate 2 322 controls the synchronous movement of each meshing block 324 to drive the second support column 323 to move along the second guide groove 327, and use the second support column 323 to internally support or externally lock the end of the pump cover of the self-priming pump.

[0047] S4: The whole device is then installed on the lathe chuck 5 through the round head 42, and the round head 42 is clamped and fixed by the lathe chuck 5, and then the centering hole 22 on the top column 21 is matched with the tail cone 2 to achieve the effect of centering locking and support, and then the whole device is controlled to rotate through the spindle box control, and then the turning tool 1 is brought close to the sealing surface of the self-priming pump cover for turning. After the sealing surface at one end is turned, the self-priming pump cover is removed, and the steps in S1-S4 are repeated to turn the sealing surface of the other end of the self-priming pump cover.

[0048] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
