Description

Technical Field

[0001] This technical solution relates to the field of cooling pump assembly equipment technology, specifically to an automatic assembly equipment for machine tool cooling pumps. Background Technology

[0002] A cooling pump is a mechanical device that drives the cooling medium (such as water, coolant, etc.) to circulate in a forced manner, transferring and dissipating the heat generated in the equipment or process. It generates power through the rotation of the impeller, which causes the medium to flow in a closed system, absorb heat and carry it to the heat dissipation equipment, thereby achieving temperature control and system cooling.

[0003] In current cooling pump production, cooling pumps differ from ordinary pumps in that they have an unconventional shape, making automated assembly difficult. The main body of a cooling pump consists of a casing and a pump body, with baffles between them. First, the casing is bolted to the end of the casing, then the impeller is bolted to the pump body, and finally the pump cover is bolted to the end of the pump body. These installation operations require manual assembly by operators. Manual installation is time-consuming, labor-intensive, and costly, and the cumbersome process results in low efficiency, impacting production efficiency and requiring improvement. Summary of the Invention

[0004] To address the problem of low production efficiency caused by the need for manual assembly of existing coolant pumps due to their unconventional shapes, this technical solution provides an automated assembly device for machine tool coolant pumps.

[0005] The purpose of this technical solution is achieved as follows:

[0006] An automatic assembly device for a machine tool cooling pump includes a frame, several station transfer devices mounted on the frame and alignable with multiple stations for transferring workpieces from one station to the next; a cover pressing device mounted on the frame for pressing the cover and the machine barrel; a machine body screw-on device mounted on the frame for fixing a first bolt between the pressed cover and the machine barrel; and a material transfer and turning device mounted on the frame for rotating the workpiece connected with the first bolt and transferring it to another station transfer device. The machine includes: an impeller pressing device mounted on the frame for pressing the impeller onto the pump body after the workpiece has rotated; an impeller screwing device mounted on the frame for connecting a second bolt between the pressed impeller and the pump body for fixing; a pump cover mounting device mounted on the frame for mounting the pump cover onto the pump body equipped with the impeller; a pump cover screwing device mounted on the frame for connecting a third bolt between the pump cover and the pump body for fixing; and a feeding device mounted on the frame for removing the workpiece connected with the third bolt for feeding.

[0007] Through the above technical solution, an automatic assembly equipment for machine tool cooling pumps, when in normal use, forms a circular production line with a station transfer device as the basis for cyclical conveying. Its workflow has a clear temporal logic: the cover pressing device presses the cover and the barrel together; the machine body screwing device screws in the first bolt for fixation; the material transfer and flipping device picks up the workpiece, rotates it at a specific angle (180 degrees) in the air, and then transfers and places it on the next stage station transfer device, with the pump body facing upwards for easy assembly; the impeller is pressed into the pump body by the impeller pressing device and fixed by the impeller screwing device with the second bolt; the pump cover installation device picks up the pump cover from the storage position and assembles it onto the pump body, and then the pump cover screwing device finally locks it with the third bolt; finally, the unloading device removes the finished product from the end station. Throughout the process, each device operates sequentially along the station transfer device, realizing the automatic flow and precise alignment of the workpiece between different processes, integrating the originally scattered manual assembly actions into a continuous and directional automated process, and improving production efficiency.

[0008] Preferably, the cover pressing device includes a pressing assembly and a pressing and fixing assembly; the pressing assembly includes a pressing seat, a pressing frame sliding on the pressing seat, and a pressing drive, the lower end of the pressing frame being provided with a pressing block; the pressing and fixing assembly includes a pressing and fixing seat, a pressing and fixing member sliding on the pressing and fixing seat, and a pressing and fixing drive, the pressing and fixing member being parallel to the moving direction of the pressing frame; the pressing and fixing drive drives the pressing and fixing member to move, the pressing and fixing member being aligned with the pressing block, and the pressing and fixing drive drives the pressing frame to move, so as to drive the pressing block to move in opposite directions in coordination with the pressing and fixing member to press and fix the cover and the barrel.

[0009] Through the above technical solution, the pressing drive drives the pressing component to move vertically, pressing and lifting the workpiece from below to move it upward; at the same time, the pressing drive drives the pressing frame to move downward, causing the pressing block at its lower end to apply pressure to the machine cover from the other upper side. The two move in opposite directions, so that the machine cover and the machine barrel are precisely pressed together between the pressing block and the pressing component, ensuring the consistency and centering of the pressing force direction, avoiding workpiece deformation caused by unilateral pressure, and improving assembly accuracy and consistency.

[0010] Preferably, the screw-on device for the machine body includes:

[0011] Bolt feeding assembly 1, which is used to feed the first bolt to bolt mounting assembly 1;

[0012] A bolt mounting assembly 1 includes a frame 1, a bolt mounting structure 1 that slides on the frame 1, and a first driving member. The first driving member drives the bolt mounting structure 1 to move back and forth. The bolt mounting structure 1 includes a bolt mounting bracket 1 that slides on the frame 1, an upper screw driving member 1, and a bolt installer 1 that slides on the bolt mounting bracket 1. The upper screw driving member 1 drives the bolt installer 1 to move up and down. The bolt installer 1 is used to acquire a first bolt and pass it through the cover and tighten it into the bolt hole of the machine body.

[0013] Through the above technical solution, the first driving component drives the bolt mounting bracket to move back and forth, thereby driving the bolt installer to move back and forth. The screw-on driving component drives the bolt installer to move up and down. Through the cooperation of the two vertical movements, the bolt installer can operate flexibly in a two-dimensional plane. When the bolt installer is aligned with the discharge port of the bolt feeding assembly, the bolt installer uses negative pressure to pick up the first bolt. When the bolt installer moves to the hole on the cover, it is driven to move down and rotate, so that the first bolt passes through the cover and is screwed into the screw hole of the machine body, thus completing the axial fixation of the cover. The two screw-on devices on the machine body respectively install two bolts at opposite corners of the machine body, realizing the automatic installation of the cover.

[0014] Preferably, the material transfer and flipping device includes: a material transfer frame, which is disposed on the machine frame and between two station material transfer devices; a material transfer slide, which is slidably disposed at the top of the material transfer frame; a flipping assembly, which is disposed on the material transfer slide, the flipping assembly including a flipping frame sliding on the material transfer frame, a lifting drive, a flipping fixture, and a flipping drive, the lifting drive driving the flipping frame to move up and down, the flipping fixture being rotatably connected to the lower part of the flipping frame, and the flipping drive driving the flipping fixture to rotate, so that the flipping fixture clamps the workpiece baffle and rotates the workpiece; a material transfer drive, which is disposed on the material transfer frame, the material transfer drive driving the material transfer slide to move, and the material transfer slide is perpendicular to the moving direction of the flipping frame; the machine frame is provided with a lifting assembly, the lifting assembly including a lifting frame, a lifting component sliding on the lifting frame, and a lifting drive, the lifting drive driving the lifting component to move, for pushing the workpiece toward the flipping fixture.

At this time, the lifting drive drives the lifting component to move and push the workpiece upward, and the lifting drive drives the flipping frame to descend vertically, so that the flipping fixture reaches and clamps the baffle on the workpiece. The lifting drive lifts back and raises the workpiece to a safe height. The flipping drive drives the flipping fixture and the workpiece to rotate 180 degrees around the horizontal axis, changing the spatial orientation of the pump body and the machine body. The material transfer drive drives the workpiece to move to the top of the transfer device at the target station. After the workpiece is placed in the target material carrier, the fixture is released and reset. Its movement path is a combination of lateral movement, vertical lifting, and rotational movement, which realizes the spatial crossing and posture change of the workpiece between the transfer devices at different stations, which facilitates the subsequent assembly process of the pump body.

[0016] Preferably, the workstation transfer device includes a turntable drive base, a transfer table rotatably disposed on the turntable drive base, and a plurality of material carriers. The plurality of material carriers are distributed circumferentially around the rotation axis of the transfer table. Each material carrier is provided with a plurality of positioning pins for positioning through the through holes of the baffle plates. Each material carrier is connected to the transfer table by a clearance hole. The turntable drive base is used to drive the transfer table to rotate, thereby driving the material carriers to switch between different workstations.

[0017] The transfer seat is equipped with a mounting assembly, which includes a mounting base, a mounting structure, and a steering drive. The steering drive is used to drive the mounting structure to rotate. The mounting structure includes a mounting frame rotatably mounted on the mounting base, a mounting slide plate sliding on the mounting frame, and a mounting slider sliding at the front end of the mounting slide plate.

The mounting slide plate is equipped with a second moving drive for driving the mounting slider to move. The mounting slider is equipped with a mounting pin for abutting against the machine body for positioning.

[0018] Through the above technical solution, the through hole of the baffle plate is aligned with the positioning post for insertion, achieving precise positioning of the workpiece. The steering drive drives the fixed assembly structure to rotate and adjust its position. The first moving drive drives the fixed assembly slide plate to move back and forth, and the second moving drive drives the fixed assembly slider to move up and down, so that the positioning pin is aligned with the machine body for pressing and positioning, restricting the free rotation of the machine body before the bolts are fixed. The turntable drive seat drives the transfer table to rotate intermittently, causing the circumferentially distributed material carriers on it to pass through each assembly station in sequence. The clearance holes of the transfer table and the material carriers are connected to each other, providing clearance space for the movement of the lifting and pressing parts below, allowing them to pass through or extend into the workpiece. Through the periodic rotation of the transfer table, the workpiece is automatically and accurately transported to each station such as pressing, screwing, flipping, and unloading, realizing the rhythmic connection of the process and forming a continuous assembly loop.

[0021] Preferably, the impeller screw mounting device includes:

[0022] Bolt feeding assembly 2 is used to feed the second bolt to bolt mounting assembly 2;

[0024] Through the above technical solution, the second driving component drives the bolt mounting bracket 2 to move back and forth, thereby driving the bolt installer 2 to move back and forth. The upper screw driving component 2 drives the bolt installer 2 to move up and down. Through the cooperation of the two vertical movements, the bolt installer 2 can operate flexibly in a two-dimensional plane. When the bolt installer 2 is aligned with the discharge port of the bolt feeding component 2, the bolt installer 2 uses suction negative pressure to pick up the second bolt. When the bolt installer 2 moves to the hole aligned with the impeller, it is driven to move down and rotate, so that the second bolt passes through the impeller and is screwed into the screw hole of the pump body, thus completing the axial fixation of the impeller and realizing the automatic installation of the impeller.

[0025] Preferably, the pump cover mounting device includes:

[0026] The pump cover material changing assembly includes a material changing disc rotatably mounted on the frame, a material changing drive unit for driving the material changing disc to rotate, and several material storage components distributed axially around the material changing disc.

The material changing drive unit drives the material changing disc to rotate, which is used to switch the alignment of different material storage components with the pump cover top material assembly.

[0027] A pump cover top material assembly includes a top material frame, a top material component sliding on the top material frame, and a top material drive component. The top material component extends below the storage tray, and the top material drive component drives the top material component to move so as to push against the storage tray and move synchronously.

[0028] A pump cover mounting assembly includes a pump cover mounting bracket, a mounting drive, a first mounting fixture and a second mounting fixture that slide on the pump cover mounting bracket. The frame is provided with a material rack, which has a centering block that matches the inner hole of the pump cover. The outer surface of the centering block has one or more rotation-limiting surfaces. The centering block also has a clearance groove for the gripping fingers of the second mounting fixture to pass through. The mounting drive drives the first and second mounting fixtures to reciprocate. The first mounting fixture is used to grip the pump cover on the top of the storage tray and transfer it to the material rack. The pump cover is positioned by fitting it onto the centering block. The second mounting fixture is used to grip the pump cover on the material rack and install it on the pump body.

[0029] Through the above technical solution, the pump cover installation device achieves automatic supply and installation of the pump cover by coordinating the pump cover transfer assembly, the top assembly and the installation assembly in a specific sequence.

[0030] The pump cover transfer assembly acts as a rotating hopper. Multiple storage units are arranged around its transfer disc. Each storage unit is connected to multiple pump covers via a mandrel. The mandrel's shape matches the inner hole of the pump cover, restricting free rotation and ensuring the stacked pump covers maintain a uniform posture during use. A turntable drive rotates the transfer disc, switching the fully loaded storage unit to a position aligned with the top-loading assembly, ensuring a continuous supply of raw materials for the pump covers. The top-loading drive pushes the top-loading component upwards, its extension lifting the storage disc and the entire stack of pump covers on it, ensuring all pump covers can be installed.

[0069] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0070] Example:

[0071] See Figure 1 and Figure 5 An automatic assembly device for a machine tool cooling pump includes a frame 1. The frame 1 is equipped with several station transfer devices 2, a cover pressing device 3, a body screwing device 4, a material transfer and tilting device 5, a fan impeller pressing device 6, a fan impeller screwing device 7, a pump cover mounting device 8, a pump cover screwing device 9, and a unloading device 10. The station transfer devices 2 can be aligned with multiple stations to transport workpieces from one station to the next. A complete workpiece includes the machine body. 100. The cover 200, baffle 300, impeller, pump body 400 and pump cover 500 installed on the body 100 are connected to the body 100 by four first bolts, the impeller and pump body 400 are connected by one second bolt, and the pump cover 500 and pump body 400 are connected by three third bolts. The baffle 300 is roughly disc-shaped and protrudes from between the body 100 and the pump body 400.

[0072] See Figure 2The workstation transfer device 2 includes a turntable drive base 9213, a transfer platform 22, and several material carriers 23. The turntable drive base 9213 is fixedly installed on the frame 1. The transfer platform 22 is located on the upper side of the turntable drive base and is rotatably arranged relative to the frame. The turntable drive base is existing technology and will not be described in detail here. It is usually driven by a motor through a worm gear structure to rotate the transfer platform 22 around its own axis. Several material carriers 23 are arranged circumferentially on the transfer platform 22 around the rotation axis of the transfer platform 22. The number of material carriers 23 is specifically set to six according to actual needs. The intermittent rotation of the transfer platform 22 drives the material carriers 23 on it to pass through each workstation in sequence. Each material carrier 23 is used to carry a single workpiece. The material carrier 23 is provided with four positioning posts 221. When the workpiece is loaded, the four positioning posts 221 are inserted and engaged with the four through holes of the baffle plate.

[0073] This embodiment shows a case where two workstation transfer devices 2 are provided. The transfer platform 22 in the workstation transfer device 2 located to the right of the transfer and flipping device 5 rotates clockwise, so that each material carrier 23 can pass sequentially through the workstations corresponding to the cover pressing device 3, the machine body screwing device 4, and the transfer and flipping device 5. The transfer platform 22 in the other workstation transfer device 2 located to the left rotates counterclockwise, so that each material carrier 23 can pass sequentially through the workstations corresponding to the transfer and flipping device 5, the impeller pressing device 6, the impeller screwing device 7, the pump cover mounting device 8, the pump cover screwing device 9, and the unloading device 10.

[0074] The first station performs two actions: first, the workpiece (i.e., the cooling pump body) is loaded manually or by a robotic arm and placed on the material carrier 23 in the station transfer device 2 on the right; second, the impeller is loaded manually or by a robotic arm and placed in the pump body in the station transfer device 2 on the left.

[0075] See Figure 4Each turntable drive unit is equipped with a mounting assembly 13, which is located at the center of the corresponding transfer table 22. The mounting assembly 13 includes a mounting base 131, a mounting structure 132, and a steering drive component 133. A portion of the housing at the upper end of the turntable drive unit passes through the transfer table 22, and the mounting base 131 is fixedly mounted on this portion of the housing. The mounting structure 132 includes a mounting bracket 1321, a mounting slide plate 1322, and a mounting slider 1323. The mounting bracket 1321 is rotatably connected to the mounting base 131 via a rotating shaft, and the mounting bracket 1321 abuts against the upper surface of the mounting base 131 via a ball bearing structure to reduce rotational friction. The steering drive component 133 is mounted on... On the mounting base 131, its output end drives the mounting frame 1321 to rotate via a transmission belt and transmission wheel structure; the mounting slide plate 1322 is slidably connected to the top of the mounting frame 1321 via a guide rail slider structure, and its sliding direction is set horizontally. The side of the mounting frame 1321 is equipped with a moving drive component 141 for driving the mounting slide plate 1322 to move back and forth; the mounting slider 1323 is slidably connected to the front side of the mounting slide plate 1322 via a guide rail slider structure, and its sliding direction is perpendicular to the sliding direction of the mounting slide plate 1322. The upper end of the mounting slide plate 1322 is equipped with a moving drive component 142 for driving the mounting slider 1323 to move up and down.

[0076] The mounting slider 1323 is provided with two mounting pins 16, which protrude from the lower end face of the mounting slider 1323. The two positioning pins are set one-to-one with the two screw holes of the cover. The rotation of the mounting bracket 1321 drives the two positioning pins to adjust their angle position. The forward movement of the mounting slide plate 1322 drives the two positioning pins to align with the two screw holes on the side of the machine body. The downward movement of the mounting slide plate 1322 drives the two positioning pins to align with the two screw holes and press them together, abutting against the machine body for initial positioning and restricting the free rotation of the machine body before the bolts are fixed. After the machine body is positioned, the mounting assembly 13 is removed and the cover is placed on the machine body.

[0077] See Figure 6 The cover pressing device 3 is located in the second working position. It includes a pressing assembly 31 and a pressing and fixing assembly 32. The pressing assembly 31 includes a pressing seat 311, a pressing frame 312 and a pressing drive 313. The pressing seat 311 is fixedly installed on the frame 1. The pressing frame 312 is slidably connected to one side of the pressing seat 311 through a guide rod structure. Its sliding direction is set vertically. A pressing block 11 is fixed at the lower end of the pressing frame 312. Its overall shape is roughly cylindrical. The pressing drive 313 is installed at the top of the pressing seat 311. Its output end is connected to the pressing frame 312 and is used to drive the pressing frame 312 to move up and down, so as to drive the pressing block 11 to press the cover downward.

[0078] The pressing assembly 32 includes a pressing seat 321, a pressing component 322, and a pressing drive 323. The pressing seat 321 is fixedly mounted on the frame 1. The pressing component 322 is located on the upper side of the pressing seat 321 and is positioned opposite to the pressing block 11. The pressing component 322 is movable relative to the pressing seat 321, and its movement direction is parallel to the movement direction of the pressing block 11. The pressing drive 323 is mounted on the side of the pressing seat 321. Its output end drives the pressing component 322 to move through a worm gear structure. The pressing component 322 abuts against and lifts the workpiece from the lower side of the workpiece. It works in conjunction with the lower pressing cover of the pressing block 11. The two move in opposite directions and apply force to ensure the consistency and centering of the pressing force direction, and avoid workpiece deformation caused by unilateral pressure. The cover and the barrel are precisely pressed together between the pressing block 11 and the pressing component 322.

[0079] See Figure 1 and Figure 7 There are two independent screw feeding devices 4 on the machine body. The two screw feeding devices 4 correspond to the third and fourth stations on the production line, respectively. Each station transfer device 2 includes a bolt feeding assembly 41 and a bolt installation assembly 42. The bolt feeding assembly 41 is existing technology and will not be described in detail here. The bolt feeding assembly 41 usually includes a bolt vibrating plate and a bolt discharge component connected to it. The bolt vibrating plate orients and sorts the bulk bolts and conveys them one by one to the preparation hole of the bolt discharge component through the conveying pipe. The preparation hole can only allow a single bolt to pass through. After the bolt is temporarily stored in the preparation hole, the bolt discharge component uses a staggered drive to send the bolt to the waiting position.

[0080] Bolt mounting assembly 42 includes a frame 421, a bolt mounting structure 422, and a first driving component 423. The frame 421 is fixedly mounted on the frame 1. The bolt mounting structure 422 includes a bolt mounting bracket 4221, an upper screw driving component 4222, and a bolt installer 4223. The bolt mounting bracket 4221 is slidably connected to the side of the frame 421 via a guide rail slider structure, and its sliding direction is horizontal. The bolt installer 4223 is slidably connected to the bolt mounting bracket 4221 opposite to the side. One side of the frame 421 moves in a direction perpendicular to the direction of movement of the bolt mounting bracket 4221. The upper screw drive component 4222 is mounted on the bolt mounting bracket 4221 and is used to drive the bolt installer 4223 to move. The first drive component 423 is mounted on the frame 421 and is used to drive the bolt mounting bracket 4221 to move, so as to drive the bolt installer 4223 to move synchronously. Through the coordinated movement of the two perpendicular directions, the bolt installer 4223 can operate flexibly in a two-dimensional plane.

[0081] When the bolt installer 4223 moves to the discharge end of the bolt feeding assembly 41, it acquires a first bolt through negative pressure adsorption. When the bolt installer 4223 moves to the hole on the cover, it is driven to move downward and rotate, passing the first bolt through the cover and screwing it into the bolt hole of the machine body, thus achieving a reliable connection and axial fixation between the cover and the machine body. It should be noted that, based on the fact that the movement of the bolt mounting bracket 4221 along the bracket 421 is limited to a single-dimensional linear movement, a single bolt mounting assembly 42 mainly completes the installation of two bolts arranged diagonally along the machine body within its working stroke; two bolt mounting assemblies 42 can install four bolts.

[0082] See Figure 2 and Figure 3 The material transfer and flipping device 5 is located at the fifth station. It includes a material transfer frame 51, a material transfer slide 52, a flipping component 53, and a material transfer drive 54. The material transfer frame 51 is installed between the two station material transfer devices 2 and is fixedly mounted on the frame 1. The material transfer slide 52 is slidably connected to the top of the material transfer frame 51 and its sliding direction is set horizontally. The flipping component 53 is installed on the material transfer slide 52. The material transfer drive 54 is installed on the material transfer frame 51 and is used to drive the material transfer slide 52 to move so as to drive the flipping component 53 to move synchronously.

[0083] The flipping assembly 53 includes a flipping frame 531, a lifting drive 532, a flipping clamp 533, and a flipping drive 534. The flipping frame 531 is movably connected to the transfer slide 52 via a slide bar structure, and its movement direction is perpendicular to the movement direction of the transfer slide 52. The flipping clamp 533 is rotatably connected to the lower end of the flipping frame 531, and its rotation axis is parallel to the movement direction of the transfer slide 52. In this embodiment, the flipping clamp 533 includes two clamping plates, with clamping grooves recessed on opposite sides. The width of the clamping grooves matches the size of the baffle. The two clamping plates approach each other and clamp the baffle through the clamping grooves. The flipping drive 534 is mounted on the flipping frame 531 and is used to drive the flipping clamp 533 to rotate. The lifting drive 532 is mounted on the flipping frame 531 and is used to drive the flipping frame 531 to move. The transfer drive 54 is mounted on the transfer frame 51 and is used to drive the transfer slide 52 to move.

[0084] Through the coordinated movement of the two vertical directions, the flipping fixture 533 can operate flexibly in a two-dimensional plane. The flipping fixture 533 picks up the workpiece from the first station transfer device 2, drives the workpiece to rotate 180 degrees, and changes the spatial orientation of the pump body and the machine body: in the original workpiece, the machine body was facing up and the pump body was facing down, and in the flipped workpiece, the pump body was facing up and the machine body was facing down. After the flipped workpiece is placed on the target material carrier 23 of the other station transfer device 2, the flipping fixture 533 releases and resets. Its movement path is a combination of lateral movement, vertical lifting and rotation, which realizes the spatial crossing and posture change of the workpiece between different station transfer devices 2.

[0085] The frame 1 is equipped with a lifting assembly 15, which includes a lifting frame 151, a lifting component 152, and a lifting drive component 153. The lifting frame 151 is fixedly installed on the frame 1 and is located below the transfer table 22. The lifting component 152 is movably connected to the lifting frame 151 through a guide rod structure. Each material carrier 23 and the transfer table 22 are correspondingly connected to a clearance hole 12 for the lifting component 152 and the pressing component 322 to pass through. During the transfer of the transfer table 22, the lifting component 152 can be aligned with any clearance hole 12. The lifting drive component 153 is installed at the lower end of the lifting frame 151 and is used to drive the lifting component 152 to move up and down. When the position of the flipping fixture 533 is aligned with the lifting component 152, the lifting component 152 pushes the workpiece towards the flipping fixture 533, so that the baffle is separated from the material carrier 23 and the baffle can be smoothly clamped by the flipping fixture 533.

[0086] See Figure 8 The impeller pressing device 6 is located at the sixth station. It includes a pressing seat 61, a pressing drive 62, and a pressing block 63. The pressing seat 61 is fixedly installed on the frame 1. The pressing drive 62 is fixedly installed on the front side of the upper end of the pressing seat 61. The pressing block 63 is set on the output shaft at the lower end of the pressing drive 62. The pressing block 63 is movable relative to the pressing seat 61. The pressing drive 62 drives the pressing block 63 to move. The pressing block 63 presses the impeller downward to make it snap and fix it to the pump body. The impeller is fed from the first station mentioned above.

[0087] See Figure 9The impeller screw-feeding device is located at the seventh station, which includes a bolt feeding assembly 71 and a bolt mounting assembly 72. The bolt mounting assembly 72 includes a frame 721, a bolt mounting structure 722, and a second drive component 723. The frame 721 is fixedly mounted on the frame 1. The bolt mounting structure 722 includes a bolt mounting bracket 7221, a second screw-feeding drive component 723, and a bolt installer 7223. The bolt mounting bracket 7221 is slidably connected to the side of the frame 721 via a guide rail slider structure, with its sliding direction horizontal. The bolt installer 7223 is slidably connected to the side of the bolt mounting bracket 7221 opposite to the frame 721, with its movement direction perpendicular to the movement direction of the bolt mounting bracket 7221. The driving component 723 is mounted on the bolt mounting bracket 7221 and is used to drive the bolt installer 7223 to move. The second driving component 723 is mounted on the bracket 721 and is used to drive the bolt mounting bracket 7221 to move, so as to drive the bolt installer 7223 to move synchronously. Through the coordinated movement of the two vertical directions, the bolt installer 7223 can operate flexibly in the two-dimensional plane. The bolt installer 7223 moves to the discharge end of the bolt feeding component 71 and obtains a second bolt by negative pressure adsorption. When the bolt installer 7223 moves to the hole on the impeller, the bolt installer 7223 is driven to move downward and rotate, so that the second bolt passes through the impeller and is screwed into the screw hole of the pump body.

[0088] See Figure 10 and Figure 11 The pump cover mounting device 8 is located at the seventh station. It includes a pump cover material changing assembly 81, a pump cover top material assembly 82, and a pump cover mounting assembly 83. The pump cover material changing assembly 81 includes a material changing disc 811, a material changing drive 812, and several material storage components 813. The material changing disc 811 is rotatably connected to the frame 1. The material changing drive 812 is installed on the lower side of the frame 1. The several material storage components 813 are distributed around the axial direction of the material changing disc 811. The material changing drive 812 drives the material changing disc 811 to rotate around its axis to switch different material storage components 813 to align with the pump cover top material assembly 82. Each material storage component 813 includes a storage rack. 8131, storage tray 8132 and core-fixing rod 8133. The storage rack 8131 is fixedly installed on the material changing tray 811. It has three rods. The storage tray 8132 is inserted into the rods through the insertion holes and is movable along the storage rack 8131. The lower end of the core-fixing rod 8133 is fixed on the storage rack 8131 and passes through the storage tray 8132. The cross-sectional shape of the core-fixing rod 8133 is a regular hexagon. The inner hole of the pump cover is designed to match the regular hexagonal hole. The pump cover is inserted into the core-fixing rod 8133. The two achieve circumferential positioning and anti-rotation through this mating surface. Multiple pump covers are stacked in a uniform posture on the storage tray 8132 for material preparation.

[0089] The pump cover top material assembly 82 includes a top material frame 821, a top material component 822, and a top material drive component 823. The top material frame 821 is mounted on the side of the frame 1 near the pump cover mounting assembly 83. The top material component 822 is slidably connected to the top material frame 821 through a guide rod structure. Its sliding direction is parallel to the moving direction of the storage tray 8132 and extends to the lower side of the storage tray 8132. When the storage tray 8132 is above the top material component 822, the top material drive component 823 drives the top material component 822 to move. The top material component 822 pushes the storage tray 8132 upward and moves synchronously with the stacked pump covers to ensure that all pump covers can be clamped by the pump cover mounting assembly 83.

[0090] The pump cover mounting assembly 83 includes a pump cover mounting bracket 831, a mounting drive component 832, a first mounting fixture 833, and a second mounting fixture 834. The pump cover mounting bracket 831 is fixedly mounted on the frame 1 and is positioned between the transfer table 22 and the material changing tray 811. The first mounting fixture 833 and the second mounting fixture 834 are slidably connected to the same side of the pump cover mounting bracket 831 and move together along the same track direction.

[0091] The frame 1 is also equipped with a material preparation rack 17, which has a core-fixing block 171 that matches the inner hole of the pump cover. The outer surface of the core-fixing block 171 has one or more rotation-limiting surfaces 1711. There are three rotation-limiting surfaces 1711, which can cooperate with the inner hole of the pump cover to prevent it from rotating. The core-fixing block 171 has three clearance grooves 1712, which are located between adjacent rotation-limiting surfaces 1711. The installation drive unit 832 drives the installation fixture one 833 and the installation fixture two 834 to the first position. The device moves back and forth between the two positions. When the two mounting clamps are in the first position, mounting clamp 1 833 clamps the top single pump cover of the storage component 813 through the clamping end, and mounting clamp 2 834 extends into the three clearance slots 1712 through the three clamping fingers 19 to open and clamp the upper pump cover on the material rack 17. When it is in the second position, the clamping end of mounting clamp 1 833 releases the single pump cover on the material rack 17, and mounting clamp 2 834 installs the pump cover onto the pump body. The above process is repeated.

[0092] See Figure 12The pump cover screwing device 9 is located at the eighth station. It includes a bolt feeding assembly 3 and a bolt mounting assembly 3 92. The bolt mounting assembly 3 92 includes a drive structure 921 and a bolt mounting structure 3 922. The drive structure 921 includes a third drive member 9211, a transmission rod 9212, and a drive seat 9213. The third drive member 9211 is fixedly mounted on the frame 1. The two ends of the transmission rod 9212 are rotatably connected to the output ends of the transmission rod 9212 and the drive seat 9213, respectively. The third drive member 9211 drives the transmission rod 9212 to rotate. The bolt mounting structure 3 922 is mounted on the front end of the drive seat 9213. The bolt mounting structure 3 922 includes a screw-on drive member 3 9221 and a bolt installer 3 9222. The bolt installer 3 9222 is connected via... The guide rail slider structure is slidably connected to the front side of the drive seat 9213. The upper screw drive component 9221 drives the bolt installer 9222 to move up and down. The drive seat 9213 rotates itself to drive the bolt installation structure 922 to rotate relative to the transmission rod 9212, so that the bolt installer 9222 can move freely within a certain range. When the bolt installer 9222 is aligned with the outlet of the bolt feeding component 3, the bolt installer 9222 sucks up the bolt by suction negative pressure. The bolt installer 9222 moves to align with the hole on the pump cover. The upper screw drive component 9221 drives the bolt installer 9222 to move down and rotate again, so that the third bolt passes through the pump cover and is screwed into the pump body. Each workpiece needs to be installed with three third bolts to realize the bolt fixation between the pump cover and the pump body.

[0093] See Figure 13 The unloading device 10 is located at the ninth station. It includes an unloading frame 101, an unloading slide 102, an unloading assembly 103, and an unloading drive component 104. The unloading frame 101 is fixedly installed on the frame 1. The unloading slide 102 is slidably connected to the top of the unloading frame 101. The unloading drive component 104 is fixedly installed on the unloading frame 101. It is used to drive the unloading slide 102 to move horizontally. The specific driving method is that the output end of the unloading drive component 104 is connected to a drive gear. The unloading frame 101 is provided with a corresponding drive groove. The inner wall of one or both sides of the drive groove along the length direction is provided with teeth. The drive gear is engaged in the drive groove and meshes with the teeth. The unloading drive component 104 drives the drive gear to rotate. The drive gear meshes with the teeth to drive the unloading slide 102 to move.

[0094] The unloading assembly 103 includes an unloading slider 1031, an unloading drive component 1032, and an unloading clamp 1033. The unloading slider 1031 slides through the unloading slide block 102, and the sliding direction is perpendicular to the moving direction of the unloading slide block 102. The unloading drive component 1032 is fixedly installed on the side of the unloading slide block 102 and is used for the unloading slider 1031 to move up and down. The unloading clamp 1033 is installed at the lower end of the unloading slider 1031. The movement of the unloading slide block 102 and the unloading slider 1031 drives the unloading clamp 1033 to move in two mutually perpendicular directions. The unloading clamp 1033 picks up the assembled workpiece, removes it from the material carrier 23, and moves it to the unloading area.

[0095] The frame 1 is equipped with a material handling device 18. After the material handling device 18 grabs the workpiece fed by the unloading fixture 1033, the unloading fixture 1033 releases the workpiece, and the material handling device 18 rotates the workpiece 90 degrees and places it horizontally on the conveying device (such as a conveyor belt) to prevent the vertically placed workpiece from falling over due to the center of gravity during the conveying process.

[0096] The specific work process of this plan is as follows:

[0097] This technical solution utilizes a circular production line with a station transfer device 2 as the basis for cyclical conveying. Its workflow has a clear sequential logic: the cover pressing device 3 presses the cover and the barrel together; the body screwing device 4 screws in the first bolt for fixation; the material transfer and flipping device 5 picks up the workpiece, rotates it at a specific angle (180 degrees) in the air, and then transfers and places it on the next stage station transfer device 2, with the pump body facing upwards for easy assembly; the impeller is pressed into the pump body by the impeller pressing device 6 and fixed by the impeller screwing device 7 with the second bolt; the pump cover mounting device 8 picks up the pump cover from the storage position and assembles it onto the pump body, then the pump cover screwing device 9 finally locks it with the third bolt; finally, the unloading device 10 removes the finished product from the end station. Throughout the process, each device operates sequentially along the station switching of the station transfer device 2, achieving automatic flow and precise alignment of workpieces between different processes. This integrates the originally scattered manual assembly actions into a continuous, directional automated process, improving production efficiency.

[0098] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments.
