Technical Field

[0001] This application belongs to the field of automation equipment technology, and specifically refers to a water pump assembly equipment. Background Technology

[0002] A swashplate pump is a high-efficiency pump with a relatively simple structure. Its core component is the swashplate, which transports fluid through its rotation. Existing swashplate pumps generally include a pump casing, a rotor and stator located within the casing, a fan connected to the rotor, end covers fixed to the casing, and valve assemblies fixed to the end covers. Due to its complex structure, especially the irregular shape of the swashplate, the automatic assembly of swashplate pumps is difficult, thus affecting its assembly efficiency.

[0010] The transfer device sequentially drives the tooling through the stator pressing device, the swashplate assembly device, and the pump head assembly device for assembly.

[0011] Furthermore, the stator press-fitting device includes:

[0012] Press-fit drive components;

[0013] The pressing function component is driven by the pressing drive component to perform lifting and lowering movements; the pressing function component has a pressing head and a pressing limiting boss located on the outer edge of the pressing end, which extend into the pump housing and abut against the stator.

[0017] Several lifting slide rods are mounted on the transfer device, with one end of the lifting slide rod connected to the pump housing placement seat and the other end connected to a lifting push plate.

[0018] The stator pressing device also includes a pressing lifting member opposite to the pressing functional component. When the tooling moves between the pressing functional component and the pressing lifting member, the pressing lifting member abuts against the lifting push plate, and the pressing functional component acts on the pump casing located on the tooling.

[0027] Furthermore, the swashplate placement seat is connected to a swashplate placement drive, and one of the swashplate placement slots of the swashplate transport assembly is opposite to the swashplate placement slot. The swashplate placement drive is used to drive the swashplate placement seat to slide so that different swashplate placement slots are opposite to the swashplate transport assembly.

[0028] Furthermore, the swashplate transport assembly includes a swashplate transport jaw, which has at least two relatively sliding transport jaws.

[0029] The swashplate transport assembly further includes a first transport claw drive component that drives the swashplate transport claw to move. The first transport claw drive component is used to drive the swashplate transport claw to slide or rotate. The first transport claw drive component is used to position the swashplate transport claw inside the swashplate and to make the two transport claw heads slide outward and abut against the inner edge of the swashplate to pick up the swashplate. Alternatively, after the swashplate is located inside the pump housing, the two transport claw heads slide inward and merge to form an abutment head that abuts against the swashplate and rotates, thereby driving the swashplate to rotate synchronously.

[0038] The pump head assembly device includes a pump head locking bit, which is connected to a pump head locking drive component. The pump head locking bit is used to drive the pump head locking bit to slide and lock the pump head on the pump housing when the pump head is located on the pump housing.

[0039] Furthermore, the suspension lifting rod is provided with several rods and passes through the pump head placement suspension. An elastic element is provided outside the suspension lifting rod, and the pump head placement suspension that slides on the suspension lifting rod is lifted by the elastic element.

[0040] The pump head locking drive is also connected to a suspension pressure plate, which is used to make the suspension pressure plate overcome the elastic element and press down on the pump head placement suspension so that the pump head falls onto the pump housing when the pump head locking drive drives the pump head locking bit to slide.

[0077] The present application will be further described below with reference to specific embodiments:

[0078] The water pump assembly equipment includes a transfer device 1, a stator pressing device 2, a swashplate assembly device 3, and a pump head assembly device 4. The transfer device 1 transports a tooling 5, which is used to place the fan blade 97, the pump casing 92, and the pump head 96. The swashplate assembly device 3 is located on one side of the transfer device 1 and is used to install the swashplate 94 into the pump casing 92 located on the tooling 5. The pump head assembly device 4 is located on one side of the transfer device 1 and is used to transport the pump head 96 on the tooling 5 and install it onto the pump casing 92 located on the tooling 5. The transfer device 1 sequentially drives the tooling 5 through the stator pressing device 2, the swashplate assembly device 3, and the pump head assembly device 4 for assembly.

[0079] like Figure 1 , 2As shown, the transfer device 1 is specifically a turntable, which is mounted on the frame 11. The tooling 5 is provided on the edge of the turntable, and workstations are arranged in sequence outside the turntable. The workstations are respectively equipped with the stator pressing device 2, the swashplate assembly device 3, and the pump head assembly device 4.

[0080] like Figure 2 As shown, the tooling 5 actually includes a base plate 51, and a pump housing placement seat 52 is provided at one end of the base plate 51. The pump housing placement seat 52 is used to place the pump housing 92. In fact, before installing the pump casing 92, the fan blades 97 need to be placed on the pump casing mounting base 52. Therefore, the water pump assembly equipment described in this application also includes a fan blade assembly assembly 6, which includes a fan blade shelf 61 on which several fan blades 97 are stacked, and a fan blade suction cup 62 located on one side of the fan blade shelf 61. The fan blade suction cup 62 realizes lifting and sliding movement and forward and backward sliding through the suction cup drive component 63. The suction cup drive component 63 is specifically a lifting slide rail slider structure and a front and rear slide rail slider structure, which is fixed on a frame 11. The front and rear slide rail slider structure drives the fan blade suction cup 62 to reciprocate between the fan blade 97 shelf 61 and the pump casing mounting base 52, and the lifting slide rail slider structure makes the fan blades 97 adsorbed on the fan blade suction cup 62 descend to the pump casing mounting base 52 and place them, thereby realizing the installation of the fan blades 97. In fact, the fan blade holder 61 includes several storage rods that pass through the gaps on the fan blades 97 to position and stack them. Several fan blade holders 61 are arranged around a fan blade conveying turntable 64. The rotation of the fan blade conveying turntable 64 positions the stacked fan blade holders 61 on the moving path of the fan blade suction cup 62 for transport by the fan blade suction cup 62. Furthermore, the pump housing mounting base 52 is provided with blade grooves 521 corresponding to each blade of the fan blades 97. The fan blades 97 are positioned in the pump housing mounting base 52 by positioning each blade within the blade groove 521.

[0081] After the fan blades 97 are installed, the transfer device 1 continues to move, causing the pump housing placement seat 52 to enter the next station. The next station is used to place the pump housing 92, the rotor within the pump housing 92, the pump housing connection end 93 on one side of the pump housing 92, and the pump head 96. The stator within the pump housing 92 is directly fixed into the pump housing 92 during its manufacturing process. Figure 1 , 4As shown, this step can be done manually by workers. During placement, the fan blades on the pump housing mounting base 52 are manually adjusted so that they are engaged in the blade grooves 521. Simultaneously, during the installation of the pump housing 92, the rotor of the pump housing 92 is connected to the fan blades. After the rotor installation is completed, the pump housing connecting end 93 is installed at the end of the pump housing 92. The pump housing connecting end 93 is sleeve-shaped 71 and has an opening 931 through which the stator and rotor located inside the pump housing 92 are press-fitted. The pump head 96 is connected through the pump housing connecting end 93. The pump head 96 is placed on the pump head mounting base 53 located on one side of the pump housing mounting base 52, and is also placed manually.

[0082] After manual placement is completed, the transfer device 1 moves the tooling 5 to the next station, which is equipped with a stator pressing device 2. Figures 8-10 As shown, the stator pressing device 2 includes a pressing drive 21 and a pressing functional component 22 driven by the pressing drive 21 to perform lifting and lowering movements; the pressing functional component 22 has a pressing head 221 that extends into the pump housing 92 and abuts against the stator, and a pressing limiting boss 222 located on the outer edge of the abutting end. Figure 8 , 9 As shown, the press-fitting drive component 21 includes a motor push rod, which is fixed on a frame 11. The frame 11 is used to position the motor push rod above the tooling 5 and opposite the pump housing placement seat 52 on the tooling 5. The press-fitting functional component 22 is provided at the end of the motor push rod.

[0083] The press-fitting functional component 22 is specifically a cylindrical metal part with a cylindrical press-fitting head 221 at its lower end that is adapted to the size of the opening 931 on the pump housing connection end 93. The edge of the press-fitting head 221 is formed with a press-fitting limiting boss 222. During operation, the motor push rod drives the press-fitting functional component 22 to move downward, so that the press-fitting head 221 passes through the opening 931 on the pump housing connection end 93 and abuts against the rotor located in the pump housing 92. Then, it continues to press down to achieve press-fitting. After the press-fitting functional component 22 has moved a certain distance, the press-fitting limiting boss 222 abuts against the end face of the pump housing connection end 93, which indicates that the press-fitting is in place, thus preventing the press-fitting head 221 from pressing too inward and damaging the rotor.

[0084] Since the tooling 5 in this application is set on the turntable, in order to reduce the pressure received by the turntable, such as Figure 4 , 5As shown, the pump housing placement seat 52 has several positioning blocks 522 along its edge. The pump housing placement seat 52 is positioned in a plane by the positioning blocks 522 abutting against the edge of the pump housing placement seat 52. There are four positioning blocks 522, which are located at the four corners of the pump housing placement seat 52. The positioning blocks 522 are slid by air valves. The four positioning blocks 522 are simultaneously clamped inward or opened outward under the action of the air valves. During the inward clamping process, the four positioning blocks 522 are respectively limited to the four corners of the pump housing placement seat 52, thereby positioning the pump housing placement seat 52 in the longitudinal and transverse directions.

[0085] It should be noted that the base plate 51 of the tooling 5 is provided with a sliding groove for the positioning block 522 to slide, and simultaneously accommodates the air valve structure that drives the positioning block 522 to slide. At the same time, positioning slots 523 are provided at the four corners of the pump housing mounting base 52 for the positioning block 522 to be inserted into. The insertion of the positioning block 522 makes its positioning more stable. The pump housing mounting base 52 is also connected to several lifting slide rods 524, such as... Figure 5 As shown, the lifting slide rod 524 passes through the transfer device 1. Specifically, it passes through the turntable and the base plate 51 of the tooling 5 and is connected to the pump housing placement seat 52 by fasteners. The other end of the lifting slide rod 524 is located below the turntable, and a lifting push plate 525 is connected between the other ends of several lifting slide rods 524. Under normal conditions, under the gravity of the pump housing placement seat 52, the pump housing placement seat 52 pushes the lifting slide rod 524 downward. When a force is applied to the lifting push plate 525, it pushes the pump housing placement seat 52 upward. It should be noted that the positioning block 522 only limits the pump housing placement seat 52 in the longitudinal and transverse directions, so the lifting of the pump housing placement seat 52 is not affected.

[0086] like Figure 5 , 9 As shown, the stator pressing device 2 also includes a pressing lifting member 57 opposite to the pressing functional component 22. When the tooling 5 moves between the pressing functional component 22 and the pressing lifting member 57, the pressing lifting member 57 abuts against the lifting push plate 525, and the pressing functional component 22 acts in the pump housing 92 located on the tooling 5. Figure 9 As shown, the pressing and lifting member 57 is located below the turntable and below the lifting push plate 525. The pressing and lifting member 57 can be driven to move upward by a motor push rod. When the pressing function member 22 acts on the pump housing 92 located on the tooling 5, it can simultaneously press upward against the lifting push plate 525 to counteract the pressure of the pressing function member 22 on the turntable, thereby protecting the turntable and increasing its working life.

[0087] Furthermore, the stator pressing device 2 also includes a pump housing connection end locking drive 23 and a plurality of pump housing connection end locking bits 24, such as... Figure 10 As shown, the pump housing connection end locking drive 23 and the pump housing connection end locking bit 24 are located at the next work station. The pump housing connection end locking drive 23 is specifically a lifting slide block structure, which is mounted on a frame 11. The frame 11 positions the lifting slide block structure above the tooling 5. After the stator in the pump housing 92 is press-fitted, the transfer device 1 continues to operate, positioning the pump housing at the pump housing connection end locking drive 23. The pump housing connection end locking drive 23 lifts and moves several pump housing connection end locking bits 24 to lock several screws located on the edge of the pump housing connection end 93, thus achieving assembly. In fact, a pressing lifting component 57 is also provided below the turntable at the locking drive and the pump housing connection end locking bit 24, which is used to lift the tooling 5 when the screws are tightened, thereby relieving the pressure exerted on the tooling 5 and the transfer device 1 when tightening the screws.

[0088] After the pump housing connection end 93 is locked, the tooling 5 continues to be moved by the transfer device 1 to the swashplate assembly device 3 to install the swashplate 94. The swashplate assembly device 3 includes a swashplate placement seat 31, a swashplate transport assembly 32, a swashplate locking assembly 33, and a swashplate bearing mounting assembly 34. Figure 11 As shown, specifically, the tooling 5 is further driven by the transfer device 1 to the next station. The next station is provided with a swashplate placement seat 31 and a swashplate transport assembly 32. The swashplate placement seat 31 is located on one side of the transfer device 1. The swashplate placement seat 31 is provided with a plurality of swashplate placement slots 311 for placing different swashplates 94 through different swashplate placement slots 311. The swashplate transport assembly 32 is used to transport the swashplates 94 to the tooling 5.

[0089] like Figure 12 As shown, the swashplate placement seat 31 is specifically a square flat plate with three swashplate placement slots 311 open to one side. The open side of each slot 311 is used to connect to a vibratory feeder, allowing the swashplate 94 to be gradually fed into the slot 311 via the vibratory feeder. Different swashplates 94 are placed in different slots 311. Because this application has three swashplate placement slots 311, three different swashplates 94 can be provided for assembly. The swashplate transport assembly 32 will select different swashplates according to the actual assembly requirements of the water pump and transport them to the tooling 5 for installation.

[0090] The swash plate placement seat 31 is connected to a swash plate placement drive 312. One of the swash plate placement slots 311 of the swash plate transport assembly 32 is opposite to each other. The swash plate placement drive 312 is used to drive the swash plate placement seat 31 to slide so that different swash plate placement slots 311 are opposite to the swash plate transport assembly 32.

[0091] Specifically, such as Figure 12 As shown, the swashplate transport assembly 32 includes a swashplate transport jaw 321, which has at least two relatively sliding transport jaw heads 3211. One end of each transport jaw head 3211 is provided with a rotating protrusion 3212, which is used to engage with the transport jaw head 3211 to form a rotating head 3213 when the transport jaw head 3211 slides inward. The swashplate transport assembly 32 also includes a first transport jaw drive member 3214 for driving the swashplate transport jaw 321 to move. The first transport jaw drive member 3214 is used to drive the swashplate transport jaw 321 to slide or rotate.

[0092] The first transport claw drive 3214 is specifically a transverse slide rail slider structure and a lifting cylinder driven by the front and rear slide rail slider structure. The lifting cylinder in turn drives a rotary cylinder. The front and rear slide rail slider structure and the lifting cylinder are both supported by a bracket and located above the swashplate placement seat 31. The front and rear slide rail slider structure can drive the lifting cylinder to slide between the swashplate placement seat 31 and the tooling 5 for transport. Since the first transport claw drive 3214 only has a forward and backward sliding function, the swashplate placement drive 312 is needed to adjust the position of the swashplate placement seat 31 so that different swashplate placement slots 311 are opposite to the swashplate transport claw 321 to realize the transport of different swashplates 94. Specifically, the swash plate placement drive 312 is a reciprocating screw and slider structure, which is fixed on a bracket. The swash plate placement seat 31 is fixed on the slider of the reciprocating screw. The slider is driven to slide left and right by the rotation of the reciprocating screw, thereby realizing the movement of the swash plate placement slot 311.

[0093] like Figure 12As shown, the swashplate transport jaw 321 includes a jaw base 3215 and a transport jaw head 3211 located on the jaw base 3215. The transport jaw head 3211 is generally L-shaped. The flat part of the transport jaw head 3211 slides on the jaw base 3215, and its other end, the abutment protrusion 3212, protrudes outward. The transport jaw head 3211 is pneumatically opened or closed. Since the swashplate 94 in this application is provided with an annular wall 951 formed on the side of the swashplate 94, the first transport jaw drive member 3214 can bring the transport jaw head 3211 into the annular wall 951 of the swashplate 94, and then open it outward so that the two transport jaw heads 3211 abut against the inner side of the annular wall 951. At this time, the swashplate 94 can be lifted upward to remove it, or the transport jaw head 3211 can be clamped on the outer side of the annular wall 951 for transport by clamping. After being transported into the pump housing 92, the two transport claws 3211 slide inward and merge to form a rotating head 3213. At this point, the rotating head 3213 abuts against the swashplate 94 and moves under the action of the rotary cylinder. The rotating head 3213, through friction, drives the swashplate 94 to rotate. It should be noted that the swashplate 94 and the rotor have corresponding protrusion-groove structures. Therefore, the swashplate 94 needs to be rotated so that the protrusions on the swashplate 94 correspond to the grooves on the rotor in order to engage the swashplate 94 onto the rotor for installation. Furthermore, a screw hole for connecting to the rotor is provided at the center of the swashplate 94. The rotating head 3213 can directly abut against this screw hole to rotate the swashplate 94. Further, a sharp part 3216 can be provided on the rotating protrusion 3212, which makes the end of the merged rotating head 3213 sharper, thereby facilitating the insertion of the rotating head 3213 into the screw hole for abutment and rotation.

[0094] After the swashplate 94 has completed its transport, the tooling 5 is moved to the next station, where the swashplate locking assembly 33 is installed to lock the swashplate 94 located inside the pump housing 92. Specifically, the swashplate locking assembly 33 includes a swashplate locking drive 331 and at least two adjacent swashplate locking bits 332. The swashplate locking bits 332 are driven by the swashplate locking drive 331 to slide, controlling the corresponding swashplate locking bit 332 to lock the swashplate 94 on the pump housing 92 according to the different swashplates 94 being transported by the swashplate transport assembly 32. Figure 13As shown, the swashplate locking drive 331 includes a transverse slide rail slider structure and a lifting slide rail slider structure driven by the transverse slide rail slider structure. The swashplate locking bit 332 is provided on the slider of the lifting slide rail, with two swashplate locking bits 332 positioned one in front of the other. The transverse slide rail slider structure can control its sliding distance according to the different swashplates 94 used, thereby aligning the corresponding swashplate locking bit 332 with the tooling 5 to lock the screw holes on the swashplate 94. Generally, different swashplates 94 have different inner diameters of their screw holes. In this application, two of the three swashplates 94 have the same inner diameter of their screw holes, and they can be locked using the same swashplate locking bit 332. Therefore, only two swashplate locking bits 332 are needed to lock the three swashplates 94 in this application. In practice, multiple swashplate locking bits 332 can be added according to usage requirements.

[0095] After the swashplate 94 is locked, the fixture 5 is moved to the next station, where a swashplate bearing mounting assembly 34 is provided. The swashplate bearing 95 is used to mount the swashplate 94 on the annular wall 951. In this application, the swashplate bearing 95 is pre-placed on the fixture 5. Therefore, the fixture 5 also includes a swashplate bearing placement seat 58, which has several swashplate bearing placement slots 581 arranged vertically. One side of each swashplate bearing placement slot 581 is open. The fixture also includes several swashplate bearing conveying assemblies 7, which are arranged sequentially along the conveying axis of the fixture 5. Each swashplate bearing conveying assembly 7 has a conveying channel of different heights. When the fixture 5 is moved, the open side of the swashplate bearing placement slot 581 of different heights is respectively opposite to the swashplate bearing conveying assembly 7 of the corresponding different heights, so as to convey the swashplate bearing 95 into the swashplate bearing placement slot 581.

[0096] like Figure 6 , 7As shown, the swashplate bearing placement seat 58 in this application is installed inside the base plate 51 of the tooling 5, near the center of the turntable. The swashplate bearing placement seat 58 is stepped, with bearing placement grooves on each step. It is supported by a bracket below the swashplate bearing placement seat 58. Each bearing placement groove is U-shaped and open towards the center of the turntable. The swashplate bearing conveying assembly 7 is located at the station where the pump housing 92 and pump head 96 are manually placed, and is located inside the turntable. It includes a sleeve 71 for placing the swashplate bearing 95, and a pusher 72 at the bottom of the sleeve 71. The pusher 72 is specifically a push plate driven by a cylinder. The height of the pusher 72 in each swashplate bearing conveying assembly 7 is different. Several swashplate bearings 95 are stacked in the sleeve 71. When the tooling 5 is delivered to the station equipped with the swashplate bearing conveying assembly 7, the bearing placement groove on the tooling 5 will be aligned with the pusher 72 corresponding to its height. At this time, the pusher 72 will push the swashplate bearing 95 located at the bottom of the sleeve 71 into the bearing placement groove. There are multiple swashplate bearing conveying assemblies 7. The operation of the corresponding swashplate bearing conveying assembly 7 can be controlled according to the type of water pump being assembled, and the corresponding swashplate bearing 95 will be delivered to the corresponding swashplate bearing placement groove 581. When the type of water pump being installed changes, different swashplate bearing conveying assemblies 7 are switched to operate, and they deliver different swashplate bearings 95 to the swashplate bearing placement groove 581 corresponding to the swashplate bearing conveying assembly 7, so that the swashplate bearing mounting assembly 34 can use them.

[0097] Furthermore, the swashplate bearing mounting assembly 34 includes a swashplate bearing transport claw 341 and a vibration mounting cylinder 342. The swashplate bearing transport claw 341 is connected to a second transport claw drive member 3412 that drives its sliding movement. The vibration mounting cylinder 342 is connected to a mounting cylinder drive member 3421 that drives its sliding movement. The vibration mounting cylinder 342 is provided with a vibration mounting groove 3422. Figures 14-16 As shown, the second transporter claw drive 3412 consists of a front-to-back sliding cylinder and a lifting sliding cylinder, which are supported by a bracket. The lifting sliding cylinder drives the swashplate bearing transporter claw 341. The front-to-back sliding cylinder can cause the swashplate bearing transporter claw 341 to slide between the swashplate bearing placement groove 581 and the pump housing placement seat 52. When the swashplate bearing transporter claw 341 is located on the swashplate bearing placement groove 581, the lifting sliding cylinder can be used to place the swashplate bearing transporter claw 341 inside the swashplate bearing 95. The swashplate bearing transporter claw 341 has at least two slidable swashplate bearing transporter claw heads 3411. The swashplate bearing transporter claw heads 3411 extend into the swashplate bearing 95 and open outward to grasp the swashplate bearing 95. Then, the front-to-back sliding cylinder and the lifting sliding cylinder move sequentially to place the swashplate bearing on the pump housing 92.

[0098] The mounting cylinder drive 3421 is a lifting and sliding cylinder fixed on the bracket. The lifting and sliding cylinder is connected to a vibration connecting plate 343. The vibrating element 344 is connected to the end of the vibration connecting plate 343. A vibrating mounting cylinder 342 is connected through the vibrating element 344. The vibrating mounting cylinder 342 is cylindrical, and its inner diameter is adapted to the outer diameter of the swashplate. The vibrating mounting cylinder 342 is opposite to the swashplate 94 in the tooling 5. Under the drive of the mounting cylinder drive 3421, the vibrating mounting cylinder 342 passes through the opening 931 of the pump housing connection end 93 and is placed inside the pump housing 92 and covers the swashplate 94. Then, the swashplate bearing transport pawl 341 is driven by the second transport pawl drive 3412 to grab the swashplate bearing 95 and send it into the vibrating mounting cylinder 342 before exiting. The vibrating element 344 includes a clamping block 3441 fastened to the vibrating mounting cylinder 342, and a vibrator 3442 connected between the clamping block 3441 and the vibrating connecting plate 343. The vibrator 3442 sequentially drives the clamping block 3441 and the vibrating mounting cylinder 342 to vibrate. The vibration of the vibrating mounting cylinder 342 causes the swashplate bearing 95 to gradually fit onto the annular wall 951 of the swashplate 94. The reason for using the vibrating mounting cylinder 342 to install the swashplate bearing 95 is that the swashplate has an inclined end face, which correspondingly causes the annular wall 951 of the swashplate 94 to also be inclined. Normal press-fit installation makes it difficult to determine the installation angle. Therefore, vibration is used to gradually fit the swashplate bearing 95 onto the annular wall 951, thereby effectively reducing the installation difficulty.

[0099] After the swash plate bearing 95 is installed, the tooling 5 is driven by the transfer device 1 to the next station. In fact, the next station is equipped with an oil injection device 8, which can inject lubricating oil into the swash plate 94 and stator inside the pump housing 92. After the lubricating oil is injected, it is driven by the transfer device 1 to the next station to install the pump head 96.

[0100] like Figure 1 , 4As shown in Figure 17, the pump head 96 is mounted on a pump head mounting seat 53 located on one side of the pump housing mounting seat 52. The pump head mounting seat 53 is also located on the base plate 51 of the tooling 5. The pump head mounting seat 53 has a pump head mounting cavity 531 open towards the pump housing 92. The pump head mounting seat 53 includes a pump head mounting suspension 532, in which the pump head 96 located in the pump head mounting cavity 531 is suspended. The pump head mounting seat 53 is connected to a suspension sliding drive 5321, which drives the pump head mounting seat 53 to slide so that the pump housing 92 is located in the pump head mounting cavity 531 and the pump head is suspended on the pump housing 92. The pump head mounting seat 53 also includes a suspension lifting rod 533 connected to the pump head mounting suspension 532, which is used to raise and lower the pump head mounting suspension 532 so that the pump head 96 falls onto the pump housing 92. The pump head assembly device 4 includes a pump head locking bit 41, which is connected to a pump head locking drive 42. The pump head locking bit 41 is used to drive the pump head locking bit 41 to slide and lock the pump head 96 on the pump housing 92 when the pump head 96 is located on the pump housing 92.

[0101] like Figure 4 As shown in this application, the suspension sliding drive component 5321 is a slide rail slider structure mounted on the base plate 51. A lower lifting mounting plate 54 is provided on the slider, on which the suspension lifting rod 533 is mounted. The suspension lifting rod 533 extends upward from the lifting mounting plate, and an upper lifting mounting plate 55 is provided at its top. A pump head placement suspension 532 is slidably mounted on the suspension lifting rod 533 between the lower lifting mounting plate 54 and the upper lifting mounting plate 55, that is, the suspension lifting rod 533 passes through the edge of the pump head placement suspension 532. At this time, the suspension lifting rod 532... 3. An elastic element 56 is provided externally. The pump head placement suspension 532, which slides on the suspension lifting rod 533, is lifted by the elastic element 56. Specifically, the elastic element 56 is a spring, which lifts the pump head placement suspension 532 upward. The pump head placement suspension 532, the upper lifting mounting plate 55, and the lower lifting mounting plate 54 are all U-shaped, thus forming a pump head mounting cavity 531 that can accommodate the pump housing 92. The elastic force of the elastic element 56 can keep the pump head placement suspension 532 at a higher height, making it higher than the pump housing 92. In fact, a cantilever 5322 is also provided on the U-shaped pump head placement suspension 532. The cantilever 5322 has port slots 5323 to accommodate the two ends of the pump head 96. The two ends of the pump head 96 are respectively attached to the port slots 5323, thereby achieving suspension.

[0102] The pump head locking drive 42 includes a lifting slide rail slider structure located on one side of the tooling 5, with a plurality of pump head locking bits 41 mounted on the slider. During installation, the suspension sliding drive 5321 drives the entire pump head mounting seat 53 forward, positioning the pump housing 92 within the pump head mounting cavity 531 and placing the pump head 96 on the pump housing 92. Then, the pump head locking drive 42 drives the pump head locking bits 41 to descend. The pump head locking drive 42 is also connected to a suspension pressure plate 43, which is opposite to the cantilever 5322. During the descent of the pump head locking bits 41, the suspension pressure plate 43 passes through the upper lifting mounting plate 55. The pump head 96 is placed on the pump housing 92 by pressing down on the cantilever 5322, which is connected to the pump head placement suspension 532. The suspension pressure plate 43 overcomes the elastic element 56 to press down on the pump head placement suspension 532. Then, the pump head locking bit 41 operates to lock the pump head 96 onto the pump housing 92. After locking is complete, the pump head locking bit 41 resets, and the suspension pressure plate 43 no longer presses against the cantilever 5322, allowing the pump head placement suspension 532 to reset under the action of the elastic element 56. Because the existing pump head 96 requires assembly after the stator and rotor are installed inside the pump housing 92, and due to its large size, it is often difficult to automatically load using components such as chucks. This results in the existing pump head 96 requiring multiple manual loading operations to assemble the water pump. This application uses a pump head 96 with a pump head mounting cavity 531 to enable the water pump in this application to be installed inside and outside the pump only once by loading the casing, which reduces the manual loading steps and speeds up the water pump manufacturing efficiency.

[0103] Once the pump head 96 is installed, the water pump installation is complete. At this point, the water pump can be unloaded manually or by a robotic arm. In summary, this application achieves automatic installation of a water pump with a swashplate 94 by using a fully automated transfer device 1 to drive the water pump through various assembly steps.
