Description

Technical Field

[0001] This invention relates to the field of tapping technology, and in particular to a tapping device for the base connection hole in the manufacture of deep well pumps. Background Technology

[0002] The most distinctive feature of a deep well pump is that it integrates the motor and the pump into a single unit. It is a pump that is submerged in a groundwater well to draw and transport water, and is widely used in agricultural irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Before starting the pump, the suction pipe and the pump itself must be filled with liquid. After starting the pump, the impeller rotates at high speed, and the liquid inside rotates with the blades. Under the action of centrifugal force, it is ejected from the impeller and ejected outwards. The ejected liquid gradually slows down in the diffuser chamber of the pump casing, and the pressure gradually increases before flowing out from the pump outlet through the discharge pipe. In real life, the application of deep well pumps is becoming increasingly common. During the manufacturing of deep well pumps, the connecting holes in the pump base need to be tapped; therefore, tapping equipment is required.

[0003] For example, Chinese Patent Publication No. CN223406131U describes a three-station rotary table tapping machine for pump body processing, comprising a support table, support legs, a tapping head, and a base. The base is located on the bottom surface of the tapping head and is situated on the upper surface of a support plate. Two opposing grooves are symmetrically formed on the upper surface of the support plate, and each groove has a base on its inner wall. A first adjustment groove is formed at the front end of each groove, and a second adjustment groove is formed on one side of the first adjustment groove. The first and second adjustment grooves are parallel to each other. A first support block is slidably connected to the inner wall of the first adjustment groove. The inner wall of the second adjusting groove is slidably connected to a second support block. The same end of the first and second support blocks is fixedly installed with a vertically upward-facing baffle. The two ends of the machine base are respectively located between one side of the inner wall of the groove and the top side of the baffle. By setting two grooves on the upper surface of the support plate, a machine base for a tapping head can be placed on the inner wall of the groove, which is convenient for multi-station processing. In addition, the setting of the grooves makes it easy for the tapping head to be positioned on the bottom machine base, and it is convenient to directly assemble multi-station tapping heads for use. This device forms multiple stations by opening multiple grooves, which can reduce costs.

[0004] In existing technical references, multi-station tapping can be performed using multiple tapping heads. However, with this design, as the tapping head taps, the amount of chips gradually increases and accumulates at the connection hole between the tapping tool and the pump body on the tapping head. This causes the rotating tapping tool to be squeezed and rubbed against the chips, which is especially problematic for deep holes. This hinders chip removal, affecting the normal operation of the tapping tool and, in severe cases, can lead to its breakage. Furthermore, tapping the connection hole may result in misaligned threads. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution:

[0006] A tapping device for the base connection hole in deep well pump manufacturing, comprising:

[0007] The main body, and the frame fixedly installed on the top side of the main body;

[0008] The tapping mechanism includes a hydraulic cylinder and a tapping host. The hydraulic cylinder is fixedly installed on the top of the frame, and the tapping host is fixedly installed on the telescopic end of the hydraulic cylinder. A machining tap is detachably fixedly installed on the output end of the bottom of the tapping host. A chip guide groove is provided at the die on the outer side of the machining tap. A chip blowing component is installed on the surface of the tapping host and near the machining tap.

[0009] The tapping machine has six taps evenly distributed around its bottom along the circumference, which can simultaneously tap multiple connection holes of the deep well pump base. Compared with the traditional method of tapping one tap at a time, this shortens the processing time of a single workpiece. At the same time, the drive structure with dual hydraulic cylinders installed symmetrically and vertically provides balanced and stable downward and upward driving force to the tapping machine, effectively avoiding deviation and shaking, and ensuring the consistency of synchronous feed of multiple taps. This not only improves the overall efficiency of batch processing, but also ensures the uniformity of tapping depth and verticality of each connection hole, making it suitable for standardized batch production operations.

[0010] After the base connection hole of the deep well pump is tapped, the tapping machine drives the machining tap to reverse. At the same time, the extension and retraction of the hydraulic cylinder's extension end causes the machining tap to retract, separating the machining tap from the base of the deep well pump, which facilitates the unloading of the deep well pump base.

[0011] The chip blowing assembly includes a blower, a conical guide bucket, and a tee connector. The blower is fixedly installed on the side of the tapping host surface. The conical guide bucket is fixedly installed at the bottom of the tapping host and close to the tap being processed. The tee connector is fixedly installed at the top of the tapping host. The air outlet at the bottom of the tee connector passes through the center of the tapping host and extends to its bottom. The inner wall of the conical guide bucket is fixedly connected with guide vanes. A right-angle pipe is detachably fixedly installed between the air outlet at the top of the blower and the air outlet on the surface of the tee connector. A connecting branch pipe is fixedly installed between the air outlet at the bottom of the tee connector and the conical guide bucket.

[0012] Two symmetrically positioned blowers blow air downwards, and a connecting air path is formed by right-angle pipes, tee connectors, and connecting branch pipes. The airflow is guided into the conical guide bucket on the side of the corresponding tap. With the spiral guide vanes inside the conical guide bucket, the airflow forms a high-speed vortex around the tap. This not only increases the range of airflow that can blow away chips, removing residual chips and debris from the inside of the hole and the surface of the tap in an all-round, thorough manner, but also uses the centrifugal force generated by the vortex to throw the chips out, preventing chip and debris accumulation. The dual chip removal structure works together to achieve real-time chip removal and cleaning during the tapping process, completely eliminating problems such as substandard thread accuracy, workpiece scrap, and accelerated tool wear caused by chip residue. This significantly improves the smoothness and machining accuracy of the finished thread, effectively extends the service life of the tap, and reduces equipment consumable replacement costs.

[0013] A feeding mechanism is installed at the middle of the top of the machine body.

[0014] Furthermore, the feeding mechanism is used to support the deep well pump base that needs tapping, and continuously feeds material by rotation through a dual-station system.

[0015] The feeding mechanism includes a driver and a support shaft. The driver is fixedly installed inside the machine body. The support shaft is rotatably installed at the middle of the top of the machine body via a bushing. A worktable is fixedly installed at the top of the support shaft. A bearing disc is detachably fixedly installed on the side of the top of the worktable. A limit pin is fixedly connected to the side of the top of the bearing disc. An auxiliary component is installed on the surface of the worktable near the support shaft.

[0016] Furthermore, the driver is a servo motor, the support shaft is vertically installed, the bottom end of the support shaft is fixedly installed to the output end of the servo motor through a coupling, there are two bearing disks, and the two bearing disks are symmetrically installed along the center of the worktable, and the limiting pins are evenly distributed on the top side of the bearing disks.

[0017] Furthermore, the auxiliary component includes a support housing and a square connecting column. The support housing is fixedly installed between the bottom of the worktable and the surface of the support shaft. The square connecting column is fixedly installed on the top of the worktable, near the bearing disc. A wedge-shaped pressure block is fixedly connected to the top of the square connecting column. A strip-shaped groove is formed on the inclined surface of the outer side of the wedge-shaped pressure block. A square locking hole is formed on the bottom of the outer side of the square connecting column. A reset spring is fixedly connected between the top of the inner cavity of the support housing and the middle of the surface of the square connecting column. Limiting pins are evenly distributed on the top of the bearing disc. Inserted into the connecting hole at the bottom of the deep well pump, the pump body can be quickly positioned. The servo motor output drives the support shaft to rotate the worktable 180 degrees. Two bearing discs are symmetrically arranged on the worktable, forming a dual-station alternating loading and unloading structure. During processing, while the workpiece is being tapped at one station, the workpiece can be picked up, placed, and pre-positioned at the other station. The worktable rotation enables rapid switching between stations without stopping the machine to wait for loading and unloading, solving the drawbacks of traditional single-station tapping equipment that requires machine stoppage and processing interruption for loading and unloading.

[0018] Furthermore, the square connecting columns are installed vertically, and there are four square connecting columns, which are evenly distributed on the top of the worktable and close to the bearing disc. The bottom of the square lock hole cavity is inclined.

[0019] Furthermore, the hydraulic cylinders are installed vertically, there are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the tapping machine. There are six machining taps, and the six machining taps are evenly distributed along the circumferential direction of the center of the tapping machine. The chip guide grooves are evenly distributed on the outer edge of the machining tap at the die, and the chip guide grooves are spiral-shaped.

[0020] When a rotating tap is used to tap the base of a deep well pump, a spiral chip guide groove is created at the die of the tap. The chips generated during the tapping process can be smoothly guided out along the spiral chip guide groove, avoiding the accumulation of chips in the thread groove. This effectively prevents problems such as thread scratches, chipping, and tap jamming caused by chip jamming, ensuring smooth tapping.

[0021] Furthermore, there are two blowers, which are symmetrically installed along the tapping host. There are six conical guide buckets, which are evenly distributed at the bottom of the tapping host. The guide vanes are spiral-shaped. The processing tap passes through the center of the conical guide bucket and the center of the guide vanes. The right-angle pipe, tee connector, and connecting branch pipe are connected to the conical guide bucket.

[0022] Furthermore, a clamping mechanism is installed on the top of the workbench near the supporting housing. The clamping mechanism includes a cylinder and a guide sleeve. The cylinder is detachably fixedly installed on the side of the top of the workbench, and the guide sleeve is fixedly installed on the top of the workbench near the cylinder. A locking rod is slidably installed inside the guide sleeve, and the locking rod is installed at the same height as the square lock hole. A bracket is fixedly installed on the telescopic end of the cylinder, and a sloping clamping block is fixedly installed on the top of the bracket. A flexible strip is fixedly connected to the sloping surface on the outer side of the sloping clamping block, which is driven by the contraction of the telescopic end of the cylinder. The bracket moves the inclined clamping block closer to the base of the deep well pump. The inclined clamping block clamps the side of the deep well pump base, and the locking rod is moved along with the bracket, so that the end of the locking rod engages with the square locking hole to lock and fix the positioning structure, preventing the support shaft from causing the worktable to rotate arbitrarily. The inclined clamping block has a flexible rubber strip on its inclined surface, which increases the contact friction with the workpiece and improves the clamping stability. On the other hand, it can prevent rigid clamping from causing squeezing scratches and deformation damage to the surface of the deep well pump base, effectively ensuring the appearance quality and processing accuracy of the workpiece.

[0023] Furthermore, the outer end of the locking rod is fixedly installed to the surface of the bracket, the locking rod is installed horizontally, there are two locking rods, and the two locking rods are installed symmetrically along the cylinder.

[0024] When the end of the locking rod is inserted into the square locking hole, the inclined surfaces of the two release the pressure, causing the square connecting column to be pressed downward. The square connecting column drives the wedge-shaped pressure block to move downward, and the reset spring is subjected to tension and undergoes elastic deformation. At the same time, the square connecting column and the wedge-shaped pressure block can limit and tighten the periphery of the deep well pump base. The auxiliary components and the clamping mechanism work together to ensure that the base of the deep well pump is more stable as a whole.

[0025] Furthermore, the flexible strips are evenly distributed on the inclined surface outside the inclined pressing block, and the flexible strips are made of rubber.

[0026] The equipment features a modular layout, with the machine body and frame providing stable support for the overall machining mechanism. The functional components are compactly arranged and highly coordinated. The entire process includes feed tapping, chip blowing and cleaning, station switching, and automatic clamping and positioning, significantly reducing manual intervention and minimizing machining errors caused by human error and physical strain.

[0027] The beneficial effects of the technical solution provided by this invention include:

[0028] 1. Six taps are evenly distributed around the bottom of the tapping machine along the circumference, enabling simultaneous tapping of multiple connection holes in the deep well pump base. Compared to the traditional method of tapping one tap at a time, this shortens the processing time for a single workpiece. Furthermore, the symmetrical vertical installation of dual hydraulic cylinders provides balanced and stable downward and upward driving forces, effectively preventing offset and swaying, and ensuring the consistency of synchronous feed of multiple taps. This improves the overall efficiency of batch processing and guarantees the uniformity of tapping depth and perpendicularity of each connection hole, making it suitable for standardized batch production operations.

[0029] 2. When a rotating machining tap is used to tap the base of a deep well pump, a spiral chip guide groove is opened at the die of the machining tap. The iron chips generated during the tapping process can be smoothly discharged along the spiral chip guide groove, avoiding the accumulation of iron chips in the thread machining groove. This effectively prevents problems such as thread scratches, tooth breakage, and tap jamming caused by iron chips, and ensures smooth tapping.

[0030] Third, two symmetrically arranged blowers blow air downwards, and a connecting air passage is formed by right-angle pipes, T-joints, and connecting branch pipes. The airflow is guided into the conical guide bucket on the side of the corresponding machining tap. With the spiral guide vanes inside the conical guide bucket, the airflow can form a high-speed vortex around the machining tap. This not only increases the range of airflow blowing on the chips, but also removes residual chips and debris inside the machining hole and on the surface of the machining tap in an all-round and thorough manner. Moreover, the centrifugal force generated by the vortex causes the chips to be thrown out by the centrifugal force, preventing the accumulation of chips and debris.

[0031] Fourth, by evenly distributing limiting pins on the top of the bearing disc and inserting them into the connecting holes at the bottom of the deep well pump, the main body of the deep well pump can be quickly limited. The supporting shaft drives the worktable to rotate 180 degrees. The worktable is symmetrically arranged with two bearing discs, forming a dual-station alternating loading and unloading structure. During the processing, while the workpiece is being tapped at one station, the workpiece can be picked up, placed, and pre-positioned at the other station. The worktable rotation enables rapid switching between stations without stopping the machine to wait for loading and unloading, solving the drawbacks of traditional single-station tapping equipment that requires machine stoppage and processing interruption for loading and unloading.

[0032] 5. The retraction drive bracket of the cylinder extension end moves the inclined clamping block closer to the base of the deep well pump. The inclined clamping block clamps the side of the deep well pump base, and the locking rod is moved along with the bracket, so that the end of the locking rod engages with the square locking hole to lock and fix the positioning structure, preventing the support shaft from causing the worktable to rotate arbitrarily. The inclined clamping block is equipped with a flexible rubber strip, which increases the contact friction with the workpiece and improves the clamping stability. On the other hand, it can prevent rigid clamping from causing squeezing scratches and deformation damage to the surface of the deep well pump base, effectively ensuring the appearance quality and processing accuracy of the workpiece.

[0033] 6. When the end of the locking rod is inserted into the square locking hole, the inclined surfaces of the two release the pressure, causing the square connecting column to be pressed downward. The square connecting column drives the wedge-shaped pressure block to move downward, and the reset spring is subjected to tension and undergoes elastic deformation. At the same time, the square connecting column and the wedge-shaped pressure block can limit and tighten the periphery of the deep well pump base. The auxiliary components and the clamping mechanism work together to ensure that the base of the deep well pump is more stable as a whole. Attached Figure Description

[0043] Example 1, see Figures 1-4 A technical solution is provided:

[0044] A tapping device for the base connection hole in deep well pump manufacturing, comprising:

[0045] The main body 1, and the frame 2 fixedly installed on the top side of the main body 1;

[0046] The tapping mechanism 3 includes a hydraulic cylinder 31 and a tapping host 32. The hydraulic cylinder 31 is fixedly installed on the top of the frame 2, and the tapping host 32 is fixedly installed on the telescopic end of the hydraulic cylinder 31. A machining tap 33 is detachably and fixedly installed at the output end of the bottom of the tapping host 32. A chip guide groove 34 is provided at the die on the outer side of the machining tap 33. A chip blowing assembly 35 is installed on the surface of the tapping host 32 and near the machining tap 33.

[0047] The hydraulic cylinder 31 is activated to begin operation. The extension of the telescopic end of the hydraulic cylinder 31 applies a downward pushing force to the tapping machine 32, causing it to move downwards. The machining tap 33 moves downwards along with the tapping machine 32, thus adjusting its height. The output end of the tapping machine 32 drives the rotation of the machining tap 33, facilitating the tapping of the deep well pump base. Six machining taps 33 are evenly distributed circumferentially at the bottom of the tapping machine 32, allowing for simultaneous tapping of multiple connection holes in the deep well pump base. Compared to the traditional method of tapping one tap at a time, this significantly reduces the processing time for a single workpiece. The drive structure with dual hydraulic cylinders 31 symmetrically and vertically installed provides balanced and stable downward and upward driving force to the tapping host 32, effectively avoiding deviation and shaking, and ensuring the consistency of synchronous feeding of multiple taps. This not only improves the overall efficiency of batch processing, but also ensures the uniformity of tapping depth and perpendicularity of each connecting hole, making it suitable for standardized batch production operations. After the tapping of the connecting hole of the deep well pump base is completed, the tapping host 32 drives the processing tap 33 to reverse. At the same time, the retraction linkage of the extension end of the hydraulic cylinder 31 causes the processing tap 33 to retract, and the processing tap 33 is separated from the base of the deep well pump, which facilitates the unloading of the base of the deep well pump.

[0048] The hydraulic cylinder 31 is installed vertically. There are two hydraulic cylinders 31, and the two hydraulic cylinders 31 are symmetrically installed along the tapping host 32. There are six machining taps 33, and the six machining taps 33 are evenly distributed along the circumferential direction of the center of the tapping host 32. The chip guide grooves 34 are evenly distributed on the outer edge of the machining taps 33 at the die. The chip guide grooves 34 are spiral.

[0049] When the rotating tap 33 taps the base of the deep well pump, a spiral chip guide groove 34 is opened at the die of the tap 33. The iron chips generated during the tapping process can be smoothly discharged along the spiral chip guide groove 34, avoiding the accumulation of iron chips in the thread groove. This effectively prevents the problems of thread scratches, tooth breakage, and tap jamming caused by iron chip jamming, and ensures smooth tapping.

[0050] The chip blowing assembly 35 includes a blower 351, a conical guide bucket 352, and a three-way connector 353. The blower 351 is fixedly installed on the side of the surface of the tapping host 32. The conical guide bucket 352 is fixedly installed at the bottom of the tapping host 32 and close to the processing tap 33. The three-way connector 353 is fixedly installed at the top of the tapping host 32. The air outlet at the bottom of the three-way connector 353 passes through the center of the tapping host 32 and extends to its bottom. The inner wall of the conical guide bucket 352 is fixedly connected with a guide vane 354. A right-angle pipe 355 is detachably fixedly installed between the air outlet at the top of the blower 351 and the air outlet on the surface of the three-way connector 353. A connecting branch pipe 356 is fixedly installed between the air outlet at the bottom of the three-way connector 353 and the conical guide bucket 352.

[0051] Two symmetrically arranged blowers 351 blow air downwards, and a connecting air passage is formed by a right-angle pipe 355, a three-way connector 353, and a connecting branch pipe 356. The airflow is guided into the conical guide bucket 352 on the side of the corresponding machining tap 33. With the help of the spiral guide vanes 354 built into the conical guide bucket 352, the airflow can form a high-speed vortex around the machining tap 33. This not only increases the range of airflow that can blow away chips, but also removes residual chips and debris from the inside of the machining hole and the surface of the machining tap 33 in an all-round and thorough manner. Moreover, the centrifugal force generated by the vortex causes the chips to be thrown out, preventing the accumulation of chips and debris. The dual chip removal structure works together to achieve real-time chip removal and cleaning during the tapping process, completely eliminating problems such as substandard thread accuracy, workpiece scrap, and accelerated tool wear caused by chip residue. This significantly improves the smoothness and machining accuracy of the finished thread, effectively extends the service life of the machining tap 33, and reduces the cost of equipment consumables replacement.

[0052] There are two blowers 351, and the two blowers 351 are symmetrically installed along the tapping host 32. There are six conical guide buckets 352, and the six conical guide buckets 352 are evenly distributed at the bottom of the tapping host 32. The guide vanes 354 are spiral. The processing tap 33 passes through the center of the conical guide bucket 352 and the center of the guide vanes 354. The right-angle pipe 355, the tee connector 353, and the connecting branch pipe 356 are connected to the conical guide buckets 352.

[0053] Example 2, based on Example 1, see [link / reference] Figures 1 to 6 A technical solution is provided:

[0054] A feeding mechanism 4 is installed at the middle of the top of the machine body 1.

[0055] The feeding mechanism 4 is used to support the deep well pump base that needs tapping, and uses a rotating continuous feeding method through a dual-station operation.

[0056] The feeding mechanism 4 includes a driver 41 and a support shaft 42. The driver 41 is fixedly installed inside the machine body 1. The support shaft 42 is rotatably installed at the middle of the top of the machine body 1 through a bushing. A worktable 43 is fixedly installed at the top of the support shaft 42. A bearing disc 44 is detachably fixedly installed on the side of the top of the worktable 43. A limit pin 45 is fixedly connected to the side of the top of the bearing disc 44. An auxiliary component 46 is installed on the surface of the worktable 43 and near the support shaft 42.

[0057] The driver 41 is a servo motor, the support shaft 42 is vertically mounted, and the bottom end of the support shaft 42 is fixedly mounted to the output end of the servo motor through a coupling. There are two bearing disks 44, and the two bearing disks 44 are symmetrically mounted along the center of the worktable 43. The limit pins 45 are evenly distributed on the top side of the bearing disks 44.

[0058] By evenly distributing limiting pins 45 on the top of the bearing disc 44 and inserting them into the connecting holes at the bottom of the deep well pump, the main body of the deep well pump can be quickly limited. Furthermore, through the rotation of the output end of the servo motor, the output end of the servo motor drives the support shaft 42 to rotate the worktable 43 by 180 degrees. The worktable 43 is symmetrically arranged with two bearing discs 44, forming a dual-station alternating loading and unloading structure. During the processing, while the workpiece is being tapped at one station, the workpiece can be picked up, placed, and pre-positioned at the other station. The workstation can be quickly switched by rotating the worktable 43, without stopping the machine to wait for loading and unloading. This solves the drawback of traditional single-station tapping equipment that requires machine stoppage and processing interruption when loading and unloading.

[0059] The auxiliary component 46 includes a support housing 461 and a square connecting column 462. The support housing 461 is fixedly installed between the bottom of the worktable 43 and the surface of the support shaft 42. The square connecting column 462 is fixedly installed at the top of the worktable 43 and near the bearing disc 44. A wedge-shaped pressure block 463 is fixedly connected to the top of the square connecting column 462. A strip groove 464 is provided on the outer inclined surface of the wedge-shaped pressure block 463. A square locking hole 465 is provided at the bottom of the outer side of the square connecting column 462. A reset spring 466 is fixedly connected between the top of the inner cavity of the support housing 461 and the middle of the surface of the square connecting column 462.

[0060] The square connecting posts 462 are installed vertically. There are four square connecting posts 462, and the four square connecting posts 462 are evenly placed on the top of the worktable 43 and close to the bearing disc 44. The bottom of the inner cavity of the square lock hole 465 is inclined.

[0061] Example 3, based on Examples 1 and 2, see below. Figures 1 to 8 A technical solution is provided:

[0062] A clamping mechanism 5 is installed on the top of the workbench 43 and near the support housing 461. The clamping mechanism 5 includes a cylinder 51 and a guide sleeve 52. The cylinder 51 is detachably fixedly installed on the side of the top of the workbench 43. The guide sleeve 52 is fixedly installed on the top of the workbench 43 and near the cylinder 51. A locking rod 53 is slidably installed inside the guide sleeve 52. The locking rod 53 is installed at the same height as the square lock hole 465. A bracket 54 is fixedly installed at the telescopic end of the cylinder 51. A sloping clamping block 55 is fixedly installed at the top of the bracket 54. A flexible strip 56 is fixedly connected to the sloping side of the sloping clamping block 55.

[0063] The retraction drive bracket 54 at the telescopic end of cylinder 51 moves the inclined clamping block 55 closer to the base of the deep well pump. The inclined clamping block 55 clamps the side of the deep well pump base, and the locking rod 53 is moved along with the bracket 54, so that the end of the locking rod 53 engages with the square locking hole 465 to lock and fix the positioning structure, preventing the support shaft 42 from rotating the worktable 43 arbitrarily. Furthermore, the inclined clamping block 55 has a flexible rubber strip 56 on its inclined surface, which increases the contact with the workpiece. The friction force enhances the clamping stability and avoids squeezing scratches and deformation damage to the surface of the deep well pump base caused by rigid clamping, effectively ensuring the appearance quality and machining accuracy of the workpiece. After the deep well pump base is tapped, the extension of the telescopic end of the cylinder 51 can apply an outward pushing force to the bracket 54, which will cause the inclined clamping block 55 and the locking rod 53 to be moved outward together. The inclined clamping block 55 moves away from the deep well pump base, and the end of the locking rod 53 is pulled out from the square locking hole 465, thus releasing the self-lock.

[0064] The outer end of the locking rod 53 is fixedly installed on the surface of the bracket 54. The locking rod 53 is installed horizontally. There are two locking rods 53, and the two locking rods 53 are symmetrically installed along the cylinder 51. When the end of the locking rod 53 is inserted into the square locking hole 465, the inclined surfaces of the two release the block, so that the square connecting column 462 is subjected to downward pressure. The square connecting column 462 drives the wedge-shaped pressure block 463 to move downward, and the reset spring 466 is subjected to tension and undergoes elastic deformation. At the same time, the square connecting column 462 and the wedge-shaped pressure block 463 can limit and press the periphery of the deep well pump base. The auxiliary component 46 and the pressing mechanism 5 work together to ensure that the base of the deep well pump is more stable as a whole.

[0065] Flexible strips 56 are evenly distributed on the inclined surface outside the inclined pressing block 55, and the material of flexible strips 56 is rubber.

[0066] In use, the deep well pump base that needs to be tapped is first placed on the bearing disc 44. The limiting pins 45, which are evenly distributed on the top of the bearing disc 44, are inserted into the connecting holes at the bottom of the deep well pump to quickly limit the position of the deep well pump body. The output of the servo motor drives the support shaft 42 to rotate the worktable 43 180 degrees through the rotation of the servo motor output. The worktable 43 is symmetrically arranged with two bearing discs 44 to form a dual-station alternating loading and unloading structure. During the processing, the workpiece can be tapped at one station while the workpiece is picked up and placed and pre-positioned at the other station. The workstation can be quickly switched by rotating the worktable 43.

[0067] Furthermore, the retraction drive bracket 54 of the cylinder 51 telescopic end drives the inclined clamping block 55 to move closer to the base of the deep well pump. The inclined clamping block 55 clamps the side of the base of the deep well pump, and the locking rod 53 is driven by the bracket 54 to move together, so that the end of the locking rod 53 engages with the square locking hole 465 to lock and fix the positioning structure, preventing the support shaft 42 from driving the worktable 43 to rotate arbitrarily. In addition, the inclined surface of the inclined clamping block 55 is provided with a flexible rubber strip 56, which can increase the contact friction with the workpiece, improve the clamping stability, and at the same time avoid the rigid clamping from causing squeezing scratches and deformation damage to the surface of the deep well pump base.

[0068] Furthermore, when the end of the locking rod 53 is inserted into the square locking hole 465, the inclined surfaces of the two release the pressure, causing the square connecting post 462 to be pressed downward. The square connecting post 462 drives the wedge-shaped pressure block 463 to move downward, and the reset spring 466 is subjected to tension and undergoes elastic deformation. At the same time, the square connecting post 462, in conjunction with the wedge-shaped pressure block 463, can limit and tighten the periphery of the deep well pump base.

[0069] At this time, the operator activates the hydraulic cylinder 31 to start working. By extending the telescopic end of the hydraulic cylinder 31, a downward pushing force can be applied to the tapping host 32, causing the tapping host 32 to move downward. The processing tap 33 will also move downward with the tapping host 32, thereby adjusting the height of the tapping host 32. The output end of the tapping host 32 drives the rotation of the processing tap 33, which facilitates the tapping of the base of the deep well pump. Six processing taps 33 are evenly distributed along the circumference at the bottom of the tapping host 32, which can simultaneously complete the tapping of multiple connection holes of the deep well pump base. Compared with the traditional mode of tapping one tap one by one, the processing time of a single workpiece is shortened. At the same time, the drive structure with symmetrical vertical installation of dual hydraulic cylinders 31 can provide balanced and stable downward and upward driving force for the tapping host 32, effectively avoiding the occurrence of deviation and shaking, and ensuring the consistency of synchronous feeding of multiple taps.

[0070] Moreover, when the rotating machining tap 33 taps the base of the deep well pump, a spiral chip guide groove 34 is opened at the die of the machining tap 33. The iron chips generated during the tapping process can be smoothly discharged along the spiral chip guide groove 34, avoiding the accumulation of iron chips in the thread machining groove. This effectively prevents the problems of thread scratches, tooth breakage, and tap jamming caused by iron chip jamming, and ensures smooth tapping.

[0071] Simultaneously, two symmetrically arranged blowers 351 blow downwards, and a connecting air passage is formed by a right-angle pipe 355, a three-way connector 353, and a connecting branch pipe 356. The airflow is guided into the conical guide bucket 352 on the side of the corresponding machining tap 33. With the spiral guide vanes 354 built into the conical guide bucket 352, the airflow can form a high-speed swirling flow around the machining tap 33. This not only increases the range of airflow blowing on the debris, but also removes the debris and impurities remaining inside the machining hole and on the surface of the machining tap 33 in an all-round and thorough manner. Moreover, the centrifugal force generated by the swirling flow causes the debris to be thrown out with the centrifugal force, preventing the accumulation of debris and impurities.

[0072] After the base connection hole of the deep well pump is tapped, the tapping host 32 drives the machining tap 33 to reverse. At the same time, the extension and retraction of the hydraulic cylinder 31 causes the machining tap 33 to untangle and separate from the base of the deep well pump.

[0073] By extending the telescopic end of cylinder 51 again, an outward pushing force can be applied to bracket 54, which will cause inclined clamping block 55 and locking rod 53 to move outward together. Inclined clamping block 55 moves away from deep well pump base, and the end of locking rod 53 is pulled out from square lock hole 465, thus releasing the self-lock.

[0074] At this time, the worktable 43 is rotated 180 degrees by the support shaft 42, the tapped deep well pump base is moved out, the deep well pump base to be processed is moved and loaded, and the tapped deep well pump base is removed.

[0075] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
