They typically include bearings, rotors, and gears, with concentric rings enabling the rotor and bearings to drive the gears in rotation. They are widely used across various industries. However, current processing methods rely on assembly line operations, resulting in large equipment sizes, large floor space requirements, and the need for multiple workstations on the assembly line, leading to high labor costs and limited production efficiency. Therefore, there is an urgent need for a highly automated press-fitting device with a more rational and efficient press-fitting process to meet increasingly precise processing demands and improve press-fitting efficiency.

[0004] To address this, the present invention provides an automatic press-fit device for pump cover gears, comprising: a feeding module, a bearing and gear press-fit module, a handling robot, a sealing ring installation module, and a pump cover handling module. The bearing and gear press-fit module includes a feeding module, a shifting module, and a press-fitting module.

The pump cover handling module is disposed between the press-fitting module and the sealing ring installation module. The feeding module includes a tooling plate, a pump cover clamp, a rotor clamp, a sensor, and a feeding worktable. The tooling plate is disposed on the feeding worktable. The pump cover clamp and the rotor clamp are respectively disposed at both ends of the tooling plate. The sensor is disposed next to the pump cover clamp and the rotor clamp.

[0005] The pressing process of the automatic pressing device for pump cover gears includes the following steps:

[0006] Step S1: When the sensor detects the pump cover and rotor on the pump cover clamp and rotor clamp, the handling robot sequentially clamps the rotor and pump cover and places them into the pressing module for positioning and assembly.

[0007] In step S2, the feeding module feeds the bearing into the positioning component of the shifting module, and then transfers it to the pressing module for pressing, pressing it onto the pump cover on which the rotor is assembled.

[0008] Step S3: The feeding module feeds the gear into the positioning component of the shifting module, and then transfers it to the pressing module for pressing.

[0009] Step S4: The pump cover assembly, after pressing the bearing and gear, is transported to the sealing ring mounting assembly by the pump cover transport module for sealing ring assembly;

[0010] Step S5: After the sealing ring is assembled, the pressed product is transferred to the product conveyor by the handling robot.

Each guide rod has a sliding notch below its side closest to the feeding groove, and a limit ring is provided above the sliding notch. Each guide rod has a corresponding pushing cylinder below its side furthest from the feeding groove. The bearings and gears are respectively sleeved on different guide rods. The pusher plate is slidably connected to the feeding trough via the feeding cylinder; in step S2, the bearing is first pushed into the feeding trough from the sliding notch by the pusher cylinder, and after it is in place, the pusher plate is driven by the feeding cylinder to push the bearing into the positioning component at one end of the feeding trough; in step S3, the gear is first pushed into the feeding trough from the sliding notch by the pusher cylinder, and after it is in place, the pusher plate is driven by the feeding cylinder to push the gear into the positioning component at one end of the feeding trough.

[0014] A further improvement of the present invention is that an arc-shaped limiting groove is provided on the side of the push plate near the shifting module, and the inner wall of the limiting groove is a semi-circular inner wall.

[0015] A further improvement of the present invention is that the shifting module further includes a shifting cylinder, a pneumatic gripper, and a cable chain drive assembly.

[0033] The preferred embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0034] like Figures 1 to 10 As shown, this embodiment provides an automatic press-fit device for pump cover gears, including: a feeding module 1, a bearing and gear press-fit module, a handling robot 5, a sealing ring installation module 6, and a pump cover handling module 7. The bearing and gear press-fit module includes a feeding module 2, a shifting module 3, and a press-fit module 4. The feeding module 1, the press-fit module 4, and the sealing ring installation module 6 are respectively located at different positions within the handling range of the handling robot 5. The feeding module 2 is connected to the press-fit module through the shifting module 3. 4. The pump cover transport module 7 is disposed between the pressing module 4 and the sealing ring installation module 6; the loading module 1 includes a tooling plate 101, a pump cover clamp 102, a rotor clamp 103, a sensor 104 and a loading workbench 105. The tooling plate 101 is disposed on the loading workbench 105. The pump cover clamp 102 and the rotor clamp 103 are respectively disposed at both ends of the tooling plate 101. The sensor 104 is disposed next to the pump cover clamp 102 and the rotor clamp 103.

[0035] The pressing process of the automatic pressing device for pump cover gears includes the following steps:

[0036] Step S1: When the sensor 104 detects the pump cover 9 and the rotor 10 on the pump cover clamp 102 and the rotor clamp 103, the handling robot 5 sequentially clamps the rotor 10 and the pump cover 9 and places them into the pressing module 4 for positioning and assembly.

[0037] In step S2, the feeding module 2 feeds the bearing 202 into the positioning component 302 of the shifting module 3, and then transfers it to the pressing module 4 through the shifting module 3 for pressing, pressing it onto the pump cover 9 on which the rotor 10 is assembled.

[0038] In step S3, the feeding module 2 feeds the gear 204 into the positioning component 302 of the shifting module 3, and then transfers it to the pressing module 4 for pressing through the shifting module 3.

[0039] Step S4: The pump cover assembly after pressing the bearing 202 and gear 204 is transported to the sealing ring mounting assembly 6 by the pump cover transport module 7 for sealing ring assembly;

[0040] Step S5: After the sealing ring is assembled, the pressed product is transported to the product conveyor 8 by the handling robot 5.

[0041] In this embodiment, the feeding module 2 refers to the feeding mechanism for bearings and gears, which is used to realize the automated feeding of bearings and gears; the shifting module 3 refers to the automated shifting mechanism for bearings and gears; and the pressing module 4 refers to the automated pressing mechanism for bearings and gears.

[0042] It is worth noting that in the product assembly process, the assembly of bearings and gears are two separate processes with a sequential relationship. Therefore, existing press-fitting equipment typically uses two different devices or modules to achieve this. Unlike existing technologies, such as... Figures 4 to 7 As shown, this embodiment features an optimized structural design for the feeding module 2, the shifting module 3, and the pressing module 4. This allows the feeding, shifting, and assembly of bearings and gears to be seamlessly integrated, eliminating the need for two separate devices or modules. The material handling robot 5 collaboratively handles the loading and transport between different modules, significantly reducing the size and footprint of the device and effectively lowering equipment and labor costs. Furthermore, a more rational and efficient pressing process is provided, with a high degree of automation, which effectively meets the increasingly precise processing requirements and improves the efficiency of pressing operations.

[0043] More specifically, such as Figure 3As shown, in this embodiment, there are two or more pump cover clamps 102 and rotor clamps 103. The number of pump cover clamps 102 and rotor clamps 103 is the same. Each pump cover clamp 102 and rotor clamp 103 is provided with a corresponding sensor 104 to facilitate real-time sensing of whether each pump cover clamp 102 and rotor clamp 103 has been loaded. The pump cover clamp 102 is located on one side of the tooling plate 101, and the rotor clamp 103 is located on the other side of the tooling plate 101, which is more conducive to realizing the loading of the pump cover 9 and rotor 10 at different times / steps.

[0044] More preferably, the feeding module 1 in this embodiment further includes a tooling plate moving assembly 106. The tooling plate 101 is movably mounted on the feeding worktable 105 via the tooling plate moving assembly 106 to move the required pump cover 9 or rotor 10 to a preset transport station. The preset transport station refers to a pre-set station for the transport robot 5 to perform transport operations; the tooling plate 101 can perform two-dimensional movement along the X and Y axes relative to the feeding worktable 105. The reason for this optimized design in this embodiment is that the transport robot 5 is used to realize the transport operations between the feeding module 1, the pressing module 4, and the sealing ring installation module 6. Therefore, the operation frequency and number of operations of the transport robot 5 will be relatively high, and excessively high operation frequency and number of operations may affect the overall production efficiency. The loading module 1 is only used to load the pump cover 9 and rotor 10. After each loading of the pump cover 9 and rotor 10, the handling robot 5 will only return to handle the next pump cover 9 and rotor 10 after completing step S5. This process allows sufficient time for the tooling plate 101 and tooling plate moving assembly 106. Therefore, this embodiment makes full use of this time difference in the above operation process. The tooling plate moving assembly 106 performs two-dimensional control on the tooling plate 101, thereby moving the pump cover clamp 102 or rotor clamp 103 with material to the preset handling station. The handling robot 5 only needs to return and pick up the material at the preset handling station each time, which can effectively simplify the movement path of the handling robot 5, shorten the time, and improve work efficiency.

[0045] like Figure 4 and Figure 5As shown, the feeding module 2 in this embodiment further includes guide rods 201, pushing cylinders 203, feeding grooves 205, pushing plates 206, and feeding cylinders 207. There are two or more guide rods 201, arranged side-by-side on one side of the feeding groove 205. Each guide rod 201 and its adjacent limiting post form a storage device. Each guide rod 201 has a sliding notch 208 on the side closest to the feeding groove 205, and a limiting ring 209 is provided above the sliding notch 208 to prevent two bearings 202 or gears 204 from sliding out simultaneously. Each guide rod 201 has a corresponding pushing cylinder 203 on the side furthest from the feeding groove 205. The bearings 202 and gears 204 are respectively fitted onto different guide rods 201. Thus, the feeding of the bearing 202 and the gear 204 can be achieved through the same feeding module 2; the push plate 206 is slidably connected to the feeding groove 205 through the feeding cylinder 207; in step S2, the bearing 202 is first pushed into the feeding groove 205 from the sliding notch 208 by the push cylinder 203, and after it is in place, the push plate 206 is driven by the feeding cylinder 207 to push the bearing 202 into the positioning component 302 at one end of the feeding groove 205; in step S3, the gear 204 is first pushed into the feeding groove 205 from the sliding notch 208 by the push cylinder 203, and after it is in place, the push plate 206 is driven by the feeding cylinder 207 to push the gear 204 into the positioning component 302 at one end of the feeding groove 205.

[0046] Preferably, in this embodiment, the push plate 206 is provided with an arc-shaped limiting groove 210 on the side near the shifting module 3, and the inner wall of the limiting groove 210 is a semi-circular inner wall. It is worth noting that if the inner wall of the limiting groove 210 is too long, it will be difficult to push it into the positioning component 302; if the inner wall is too short, it may fall to the side during the pushing process. Therefore, using a semi-circular inner wall is the most effective, which can avoid the disadvantages of both excessively long and excessively short inner walls, and the structure is simple and easy to implement.

[0047] More preferably, a sensor is provided next to the middle position of the guide rod 201 to sense the bearing 202 or gear 204. When the bearing 202 or gear 204 is not sensed, it indicates that the material in the guide rod 201 is less than half full, and a reminder signal is issued so that material can be added in time to avoid affecting the overall production efficiency. The pusher cylinder 203 corresponding to the bearing 202 and the pusher cylinder 204 corresponding to the gear 204 work sequentially and intermittently. That is, after pushing out a bearing 202 and confirming that it is in place, the pusher plate 206 is driven to push the bearing 202 into the positioning component 302 at one end of the feeding groove 205; then, after pushing out a gear 204 and confirming that it is in place, the pusher plate 206 is driven to push the gear 204 into the positioning component 302 at one end of the feeding groove 205; then, the cycle repeats, pushing out a bearing 202 and confirming that it is in place, to ensure a one-to-one correspondence between the bearing 202 and the gear 204 for feeding.

[0048] like Figure 6 As shown, the shifting module 3 in this embodiment further includes a shifting cylinder 301, a pneumatic gripper 303, and a cable chain drive assembly 304. The positioning assembly 302 is disposed at one end of the feeding trough 205 via the shifting cylinder 301, and the pneumatic gripper 303 is disposed above the positioning assembly 302 via the cable chain drive assembly 304. When the bearing 202 or gear 204 enters the positioning assembly 302, the shifting cylinder 301 drives the positioning assembly 302 to move to the other end, and the cable chain drive assembly 304 drives the pneumatic gripper 303 to clamp the bearing 202 or gear 204 and place it into the pressing module 4 for pressing.

[0049] It is worth noting that, in conjunction with the feeding module 2, the shifting module 3 also achieves the shifting operation of a pair of bearings 202 and gears 204 simultaneously through a single module, eliminating the need for two sets of equipment. Therefore, in this embodiment, the positioning component 302 is provided with a first positioning element 3021 and a second positioning element 3022. The first positioning element 3021 and the second positioning element 3022 have identical structures and are symmetrically arranged on the left and right sides of the positioning component 302. In actual operation, the movement of the shifting cylinder 301 causes the first positioning element 3021 and the second positioning element 3022 to sequentially position the bearings 202 and gears 204. That is, each shift is a one-to-one movement of the bearings 202 and gears 204 to correspond to one pressing operation. The control process is simple and efficient, providing a good foundation for the subsequent pressing process.

[0050] like Figure 7As shown, the press-fit module 4 in this embodiment includes a rotor positioning seat 401, a pump cover positioning post 402, an extrusion head 405, and an electric push rod 406. The pump cover positioning post 402 is located next to the rotor positioning seat 401, and the extrusion head 405 is located above the rotor positioning seat 401 via the electric push rod 406. In step S1, the handling robot 5 first moves the rotor 10 to the rotor positioning seat 401, and then moves the pump cover 9 to the rotor positioning seat 401. The rotor 10 is assembled on the pump cover positioning post 402; in step S2, the bearing 202 is moved to the top of the pump cover 9 by the shifting module 3, and the pressing head 405 is driven by the electric push rod 406 to press the bearing 202; in step S3, the gear 204 is moved to the top of the pump cover 9 by the shifting module 3, and the pressing head 405 is driven by the electric push rod 406 to press the gear 204.

[0051] like Figure 8 As shown, the sealing ring installation module 6 in this embodiment includes a pressing cylinder 601, a pump cover pressing head 602, a left sealing ring fixture 604, a right sealing ring fixture 605, a pneumatic connector 606, and a fixture cylinder 607. The left sealing ring fixture 604 and the right sealing ring fixture 605 are respectively connected to the fixture cylinder 607. The pneumatic connector 606 is disposed on the left sealing ring fixture 604 and the right sealing ring fixture 605, and is connected to the sealing ring fixture groove in the left sealing ring fixture 604 and the right sealing ring fixture 605 to form a negative pressure channel. The pump cover pressing head 602 is disposed above the left sealing ring fixture 604 and the right sealing ring fixture 605 through the pressing cylinder 601. In actual production, the fixture cylinder 607 extends to open the left sealing ring fixture 604 and the right sealing ring fixture 605, placing the sealing ring 11 into the sealing ring fixture grooves of the left and right sealing ring fixtures 604 and 605. Air holes are opened in the sealing ring fixture grooves to create negative pressure, tightly adhering the sealing ring 11 to the inner wall of the fixture. Then, the fixture cylinder 607 and the pump cover transport module place the assembled pump cover assembly 603 (pump cover 9, rotor 10, bearing 202, and gear 204) onto the sealing ring fixture. Then, the pressing cylinder 601 slowly presses down the pump cover assembly 603, causing the sealing ring 11 to enter the groove of the pump cover 9, thus assembling the sealing ring 11. Figure 9 As shown.

[0052] like Figure 10As shown, the pump cover transport module 7 in this embodiment includes a transport gripper 701 and a pneumatic component 702. The transport gripper 701 is slidably disposed next to the press-fit module 4 via the pneumatic component 702. The pneumatic component 702 drives the transport gripper 701 to transport the assembled pump cover assembly 603 from the press-fit module 4 to the sealing ring mounting module 6 for sealing ring 11 assembly. This completes the overall assembly of the product.

[0053] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
