Description

Technical Field

[0002] In the motor manufacturing process, the base plays a vital role. It supports the rotor and fixes the stator core by cooperating with the end cover, while protecting the stator winding. Traditional base processing mainly relies on CNC lathes, radial drills, single-sided milling machines and other equipment, and is equipped with corresponding molds to complete each process. However, due to the discreteness of the traditional process layout, each workstation needs to be exchanged multiple times with the help of equipment such as cranes, forklifts, and single-arm cranes, and repeatedly transported, flipped, and loaded and unloaded. This accumulation and release processing method is not only inefficient, but also leads to excessive resource occupation and increased production costs.

[0050] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0051] like Figure 1 As shown, an embodiment of the present application provides an intelligent circulation processing system for a motor base, comprising a track 5, an intelligent track trolley 6 that can reciprocate along the track 5, a workpiece circulation exchange device 4, a mold shifting device 1, and an upper material channel 2 and a lower material channel 3 for connecting the intelligent track trolley 6 and the mold shifting device 1, wherein the upper material channel 2 and the lower material channel 3 are arranged on one side of the end of the track 5; the mold shifting device 1 is configured to feed the motor base component to be processed to the upper material channel 2 and / or receive the processed motor base component from the lower material channel 3; the motor base component includes A motor base 40 and a workpiece circulation and exchange device 4 for carrying the motor base 40; the intelligent rail trolley 6 is configured to move along a first direction on a track 5, and transfer the motor base assembly from an upstream processing station to a downstream processing station in sequence to process the motor base 40; and move along a second direction on the track 5 after the motor base 40 is processed, so as to feed the processed motor base assembly to the lower material channel 3 and / or take the motor base assembly to be processed from the upper material channel 2; the first direction is opposite to the second direction.

[0052] In application, one side of the track 5 of the motor base intelligent circulation processing system 10 is distributed with multiple processing stations along the length direction of the track. These processing stations include several CNC vertical lathes 20, horizontal processing lathes, and cleaning devices 30. The CNC vertical lathes 20 and the horizontal processing lathes are used to process the motor base. The cleaning device 30 is used to clean the workpiece circulation exchange device 4. After the intelligent track trolley 6 takes over the motor base assembly to be processed from the loading channel 2, it moves along the first direction on the track 5 under the action of the travel drive motor. Whenever it passes a processing station, the workpiece on the trolley is transferred to the station, and the workpiece that has been processed in the station is retrieved, and it continues to move to the next station. When the trolley moves to the last workstation on the track 5, the motor base has completed the processing of the entire production line. At this time, the trolley takes out the processed motor base, and the rotation direction of the walking drive motor changes, so that the intelligent track trolley 6 starts to move in the second direction (i.e., return) until it walks to the unloading channel 3, and sends the processed motor base into the unloading channel 3, and at the same time connects the new motor base to be processed from the loading channel 2.

[0053] like Figure 2 As shown, in one embodiment, the mold shifting device includes a mold shifting frame 11 and a mold shifting vehicle 12; the mold shifting vehicle 12 is slidably disposed on the mold shifting frame 11, and is configured to deliver the motor base assembly to the upper material channel when sliding along the mold shifting frame 11 to a first position, and to take the motor base assembly out from the lower material channel when sliding along the mold shifting frame 11 to a second position;

[0054] Among them, the motor base assembly includes a motor base and a workpiece circulation and exchange device for supporting the motor base.

[0055] In application, the mold transfer device forms the transition section between the upper and lower lines of the workpiece. It is the station where the operator clamps and disassembles the workpiece before the machine base blank goes on line and the finished product goes off line.

[0056] In one embodiment, Figure 3 As shown, the mold transfer frame 11 includes a column 112 and a pair of parallel supporting beams 111. The supporting beams 111 are horizontally fixed on the columns 112. The mold transfer vehicle 12 is placed on the supporting beams 111 and slidably cooperates with the supporting beams 111 on both sides.

[0057] In application, the mold transfer frame 11 is mainly welded by hollow rectangular square steel, angle steel and other profiles. There are four columns 112, and the bottom of the columns 112 is respectively provided with height adjustment mounting brackets 115, so as to adjust the height of the mold transfer frame 11 appropriately and fix it reliably according to the height of the conveying chain of the upper and lower material channels.

[0058] In one embodiment, the support beam 111 is an L-shaped beam, a pair of L-shaped beams are arranged opposite to each other, the L-shaped beam includes a horizontal portion 1112 and a vertical portion 1111, and the mold transfer vehicle 12 is slidably matched with the horizontal portion 1112 at the bottom.

[0059] In application, a crossbeam 113 is welded between the columns 112 on the same side, and the two crossbeams 113 on both sides are welded and connected by two reinforcing ribs 114. An angle steel, i.e., an L-shaped support beam 111, is laid on the crossbeam 113. The lower surface of the angle steel is polished and leveled, and serves as the left and right lateral movement surface of the mold transfer trolley on the mold transfer frame. The width between the two side surfaces of the angle steel is determined according to the outer dimensions of the mold transfer trolley along the upper and lower material channels to ensure that the mold transfer trolley can flexibly and stably move left and right laterally above the mold transfer frame.

[0060] In one embodiment, the L-shaped beam is provided with a first limit block 116 and a second limit block 117. When the first limit block 116 cooperates with the mold shifting vehicle 12, the mold shifting vehicle 12 is located at the first position. When the second limit block 117 cooperates with the mold shifting vehicle 12, the mold shifting vehicle 12 is located at the second position.

[0061] In application, the first limit block 116 and the second limit block 117 are provided with a buffer block 118 on the surface in contact with the die transfer vehicle 12. The buffer block 118 can be a rubber block. When the operator drags or pulls the die transfer vehicle to make it close to and contact the limit block, the impact can be effectively reduced. The distribution position of the limit block is determined according to the loading and unloading points of the workpiece.

[0062] In one embodiment, Figure 4 As shown, the mold transfer vehicle 12 includes a bracket 121 that can reciprocate along the mold transfer frame 11, and the bracket 121 and the motor base assembly are provided with conveying smooth bars 124 at corresponding positions on both sides of the bottom. The conveying smooth bars 124 are arranged along the length direction of the upper and / or lower material channels.

[0063] In application, the die transfer vehicle 12 is used to carry the universal fixture of the workpiece and the transfer exchange worktable to realize the transition function of the workpiece between the loading channel and the unloading channel of this system. The bracket 121 is machined after cutting and blanking the steel plate. The upper and lower surfaces are parallel and smooth, and there is a hollow 1211. The hollow structure reduces weight and facilitates the installation of the workpiece on the fixture.

[0064] In application, two parallel conveying smooth bars 124 are provided on the upper plane of the bracket 121. The conveying smooth bars 124 are fixed to the bracket 121 and the smooth bar support plate 125 by screws. The motor base assembly is placed on the conveying smooth bars 124 to reduce the resistance of the workpiece in the process of pushing the workpiece into the upper material channel and dragging it out of the lower material channel. The smooth bar support plate 125 is a channel steel structure with closed ends. Its waist-shaped mounting holes are used to achieve floating adjustment of the height of the two conveying smooth bars, thereby ensuring the horizontal position of the motor base assembly.

[0065] In one embodiment, a roller 126 is disposed at the bottom of the bracket 121 for contacting the surface of the horizontal portion 1112 to achieve reciprocating movement of the bracket 121 .

[0066] In application, a group of rollers 126 are respectively arranged at the four corners of the lower plane of the bracket 121. Each group of rollers 126 is mainly composed of a plurality of standard ball bearings arranged in an array, which facilitates the rollers to be evenly loaded and replaced, so that the mold transfer vehicle 12 can move flexibly.

[0067] In one embodiment, Figure 5 As shown, guide smooth strips 127 in contact with the vertical portion 1111 are provided on both sides of the bracket 121 corresponding to the vertical portion 1111 .

[0068] In application, the guide smooth strips 127 are distributed on both sides of the bracket 121, so that the mold transfer vehicle 12 can move in a straight line between the angle steels of the mold transfer frame 11, and the sliding friction between the metals can be improved to rolling friction.

[0069] In one embodiment, side baffle assemblies 122 for limiting the two sides of the motor base assembly are provided on both sides of the bracket 121 corresponding to the moving direction, and the side baffle assemblies 122 are vertically connected to the surface of the bracket 121 .

[0070] In one embodiment, Figure 6 As shown, the side baffle assembly 122 includes a first side baffle 1221 and a second side baffle 1222 . The first side baffle 1221 is located inside the second side baffle 1222 , and the height of the first side baffle 1221 is lower than that of the second side baffle 1222 .

[0071] In application, the first side baffle 1221 and the second side baffle 1222 are used for guiding and positioning the motor base assembly in and out of the mold transfer vehicle 12. The motor base assembly includes a workpiece transfer exchange device for carrying the motor base, and the two side surfaces of the workpiece transfer exchange device are surfaces with an upper width greater than a lower width, so that they can be respectively adapted to the inner surfaces of the first side baffle 1221 and the second side baffle 1222 to achieve guiding and positioning.

[0072] In one embodiment, a rear baffle 123 is vertically connected to the surface of the bracket 121 at one side away from the upper material channel and / or the lower material channel, and the rear baffle 123 is limitedly matched with the motor base assembly.

[0073] In application, the rear baffle 123 is used to limit and fix the workpiece circulation and exchange device on the mold shifting vehicle 12, thereby ensuring the reliability of the workpiece during loading, unloading and movement in the transition section (i.e. the link corresponding to the mold shifting device).

[0074] In one embodiment, a rear baffle U-shaped groove 1231 is further provided on the top of the rear baffle 123 .

[0075] In application, the workpiece circulation and exchange device can be provided with a horizontally outwardly extending positioning buffer rivet. When the workpiece circulation and exchange device is placed on the mold transfer vehicle 12, the positioning buffer rivet is embedded in the U-shaped groove 1231, and cooperates with a downwardly opening U-shaped card plate to fix the positioning buffer rivet in the U-shaped groove 1231, thereby fixing the workpiece circulation and exchange device on the mold transfer vehicle 12.

[0076] The working process of the mold transfer device is as follows:

[0077] The mold shifting device is composed of a mold shifting frame 11 and a mold shifting vehicle 12, wherein the mold shifting frame is used as a basic structure to provide a stable sliding platform, and the mold shifting vehicle is responsible for carrying the motor base assembly and realizing reciprocating movement on the mold shifting frame to complete the clamping of the workpiece before it goes online or the disassembly operation before the finished product goes offline. When the motor base assembly needs to be sent to the feeding channel, the operator first drags the mold shifting vehicle 12 from the initial position to the first position along the support beam 111 on the mold shifting frame 11. In this process, the roller 126 at the bottom of the mold shifting vehicle rolls with the horizontal part 1112 of the L-shaped support beam 111 to ensure a smooth movement trajectory; at the same time, the guide smooth strips 127 on both sides of the mold shifting vehicle contact the vertical part 1111 of the support beam to ensure that the mold shifting vehicle moves accurately in a straight line direction. After reaching the first position, the mold shifting vehicle contacts the pre-set first limit block 116, and the buffer rubber block 118 on the limit block effectively reduces the impact force, so that the mold shifting vehicle can stop smoothly. At this time, the operator places the motor base assembly (including the motor base and the workpiece circulation exchange device) on the mold transfer vehicle bracket 121. The conveying smooth strip 124 on the bracket reduces the resistance during the push-in process, making the operation easier. In order to ensure that the motor base assembly is correctly aligned on the mold transfer vehicle, side baffle assemblies 122 are provided on both sides of the bracket. They are adapted according to the side shape of the motor base assembly and provide guiding and positioning functions; and the rear baffle 123 at one end of the bracket provides a reliable limit fixation for the motor base assembly, further ensuring its stability during transportation.

[0078] When the motor base assembly needs to be taken out from the lower channel, the above process is performed in reverse order. The operator drags the mold transfer vehicle 12 back to the second position again, at which time it contacts the second limit block 117 and stops. Subsequently, the operator can take out the motor base assembly that has been processed from the lower channel and place it on the mold transfer vehicle 12, ready to enter the next process or storage stage. It is worth noting that the conversion of the mold transfer vehicle between different positions is completed by manual operation, but the entire process adopts the design of height adjustment mounting bracket 115, roller 126, guide smooth strip 127 and limit block 116 / 117, thereby achieving an efficient and safe operation experience. In addition, a rear baffle 123 is provided on the side of the mold transfer vehicle bracket 121 away from the upper and / or lower channel, and a U-shaped groove 1231 is also provided on the top for embedding the positioning buffer rivet of the motor base assembly, and is fixed with a U-shaped card plate with an opening downward, which not only ensures the reliability of the workpiece during the loading and unloading and movement of the transition section, but also improves the safety of operation.

[0079] like Figure 7 As shown, in one embodiment, the workpiece circulation and exchange device includes a workpiece circulation and exchange worktable 42 and a universal workpiece fixture 41 for placing a motor base 40, the universal workpiece fixture 41 is fixedly connected to the upper plane of the workpiece circulation and exchange worktable 42, and the bottom of the workpiece circulation and exchange worktable 42 is provided with a guide groove 421 for guiding the workpiece circulation and exchange worktable 42 when entering and exiting the processing station, and the surface of the universal workpiece fixture 41 is provided with a stop 4111 for adapting to the motor base 40, and the center of the stop 4111 is provided with a center through hole 4112 penetrating from the top and the bottom.

[0080] In application, the workpiece circulation and exchange device is an independent unit used to realize the intelligent circulation of workpieces (i.e., motor bases) in different stations in the production line. Among them, the workpiece circulation and exchange workbench 42 is the main component for the exchange positioning and automatic clamping of workpieces installed on the workpiece universal fixture 41 between various equipment stations in the production line. It is integrally cast and processed in place after aging treatment. The design of the center through hole 4112 facilitates subsequent process operations, such as measurement, drilling, etc., while ensuring the accurate alignment of the motor base, reducing assembly errors, ensuring the consistency of product quality, and facilitating the entry of tools and the discharge of iron chips in subsequent processes. The upper plane of the workpiece circulation and exchange workbench 42 is formed by high-precision processing to form a mounting surface that matches the workpiece universal fixture 41, and the two are fixedly connected by bolts. The guide groove 421 is located at the bottom of the workbench and is designed as a T-slot structure, allowing the workbench to slide smoothly on the intelligent rail trolley or other transmission equipment. The stopper 4111 is designed as an annular stepped inner stopper, which is suitable for motor bases 40 of different specifications.

[0081] In one embodiment, Figures 8 to 11As shown, the universal workpiece fixture 41 includes a tooling plate 411 fixedly connected to the upper plane of the workpiece transfer and exchange workbench 42, and auxiliary clamping devices 412 for cooperating with the top axial limit of the motor base 40 are provided at two corners of the upper plane of the tooling plate 411.

[0082] In application, the auxiliary clamping device 412 further enhances the axial limiting effect of the motor base. By setting these devices at the two corners of the upper plane of the tooling plate 411, the motor base can be effectively prevented from deflecting or vibrating during processing, thereby improving processing accuracy and reliability. It is particularly suitable for occasions requiring high-precision processing, and can significantly reduce product defects caused by looseness and improve the yield rate. In addition, the introduction of the auxiliary clamping device makes the operation easier, reduces manual intervention, and improves production efficiency.

[0083] In one embodiment, the auxiliary clamping device 412 includes a height-adjustable connecting rod 4121 and a hook-shaped clamp 4122 disposed on the top of the connecting rod 4121 and rotatable around the axis of the connecting rod 4121 , and the hook-shaped clamp 4122 is used to cooperate with the top axial limit of the motor base 40 .

[0084] In application, the operator can adjust the height of the connecting rod according to the motor base of different specifications, and quickly lock and unlock by rotating the hook-shaped clamp. The connecting rod 4121 adopts a segmented design, and can adapt to motor bases 40 of different heights by replacing segments of different lengths or adjusting the number of segments. The hook-shaped clamp 4122 is a rotatable part. When it contacts the motor base 40, it can fit the surface of the workpiece. At the same time, the lower surface of the hook-shaped clamp is directly pressed against the oblique support ribs of the motor base bottom plate to achieve the axial limit function. The hook-shaped clamp 4122 can rotate freely before being locked, so that it can be adjusted to a suitable position before the motor base is placed, and then locked after the direction is adjusted.

[0085] In one embodiment, the stopper 4111 is an annular stepped inner stopper 4111 .

[0086] In application, the design of the annular stepped inner stop 4111 is intended to provide a unified positioning reference for motor bases of different specifications. The stop is composed of multiple concentric rings, and the difference between the inner and outer rings forms a stepped structure, which ensures the precise positioning of the motor base when it is placed. In addition, there is enough space inside the stop as a safe clearance area for the tool, ensuring that the processing of all parts of the inner chamber can be completed in one clamping, while facilitating the cleaning of the generated iron chips.

[0087] In one embodiment, the tooling plate 411 is provided with a sinker 4113 connected to the stopper on both sides of the stopper 4111. The sinker is used to avoid the fixed structure of its outer shape when the machine base is installed, and it is also convenient for the operator to self-check the total length dimensional tolerance of the finished product of the machine base to be offline, thereby providing a guarantee for improving the quality of the workpiece.

[0088] In one embodiment, the tooling plate 411 is provided with an auxiliary positioning device 413 on the outside of the auxiliary clamping device 412 for limiting cooperation with the base 401 of the motor base 40, the auxiliary positioning device 413 includes an angle positioning bracket 4131, a locking nut 4134 and a clamping bolt 4133, the auxiliary positioning device 413 is provided with a plurality of positioning adjustment holes 4131a distributed along the horizontal direction, the clamping bolt 4133 is passed through a positioning adjustment hole 4131a and abuts against the outside of the base 401, and the locking nut 4134 is threadedly connected with the clamping bolt 4133.

[0089] In application, the angle positioning bracket 4131 is fixed on the tooling plate 411, and positioning adjustment holes 4131a are drilled thereon. These holes are arranged according to different motor base foot opening distances to accommodate workpieces of various specifications. After the clamping bolt 4133 is inserted into the corresponding positioning adjustment hole, the screw-in depth can be adjusted according to actual needs so that the front end of the clamping bolt lightly presses against the outer side of the motor base foot 401. Finally, the clamping bolt is pre-tightened and prevented from loosening using the locking nut 4134 to ensure that the motor base remains stable and immobile during the entire processing process.

[0090] In one embodiment, the tooling plate 411 is provided with tooling plate mounting bolts 414 for cooperating with the tooling plate connecting holes 429 on the workpiece circulation and exchange workbench 42, tooling plate positioning screws 415 for cooperating with the tooling plate positioning pin holes 430 on the workpiece circulation and exchange workbench 42, and tightening screws 416 for cooperating with the workbench waist groove 428 on the workpiece circulation and exchange workbench 42.

[0091] In application, the connection between the tooling plate 411 and the workpiece transfer and exchange worktable 42 is realized through a "one-face two-pin" structure, that is, the lower plane of the tooling plate fits with the mating surface of the C-shaped boss (i.e., the upper boss) on the worktable, and the tooling plate positioning screw 415 is matched with the tooling plate positioning pin hole 430 to ensure the precise relative position relationship between the two. Subsequently, the tooling plate mounting bolt 414 is passed through the tooling plate connection hole 429 to firmly combine the two together. The tensioning screw 416 is embedded in the waist groove 428 of the worktable, allowing a certain degree of floating adjustment to ensure that the tooling plate can reach the optimal horizontal state during installation.

[0092] In one embodiment, Figures 12 to 15 As shown, the workpiece circulation and exchange workbench 42 includes upper bosses 422 protruding upward on both sides and a bottom boss 423 protruding downward on the bottom. The upper width of the two side surfaces of the workpiece circulation and exchange workbench 42 is greater than the lower width. The side surfaces of the workpiece circulation and exchange workbench 42 are provided with cylindrical pin holes 427 extending inward at positions with smaller width.

[0093] In use, the workpiece transfer exchange worktable 42 has a solid overall structure, and the upper bosses 422 and bottom bosses 423 on both sides enhance the structural strength. The side width variation design (wide at the top and narrow at the bottom) helps to reduce weight, and is also convenient for interactive operation with other components such as cleaning devices. The cylindrical pin holes 427 are distributed in positions with a smaller width, which can play a fixing role when the cleaning station is turned over and chip-removed to ensure the safety of the workpiece and the convenience of operation.

[0094] In one embodiment, a positioning cone bowl 424 with an opening facing downward is provided on the inner side of the bottom boss 423 of the lower plane of the workpiece transfer and exchange workbench 42 .

[0095] In application, the positioning cone 424 is designed to open downward to accommodate and closely match the tapered positioning pins on the fast positioning and clamping fixtures of various equipment. When the workpiece transfer exchange table 42 is sent into the processing area, the positioning cone 424 will contact the tapered positioning pins and automatically guide the table to the correct processing position. This matching method is more accurate than the traditional guide pin and guide sleeve, reducing positioning errors and improving processing accuracy.

[0096] In one embodiment, the workpiece transfer and exchange workbench 42 is provided with a positioning buffer pull nail 425 at one end surface along the length direction of the guide groove 421, and a material feeding and taking handle 426 is provided at the other end surface.

[0097] In application, the positioning buffer pin 425 is installed at one end of the workpiece transfer exchange workbench 42. When the workbench approaches the target station, its positioning buffer pin will contact the polyurethane PU rod on the tail baffle of the guide pressure plate to achieve slow positioning and protect the system from impact damage. The feeding and unloading handle 426 is located at the other end of the workbench. It is the key interface part for the intelligent rail trolley to push in and out the workpiece transfer exchange workbench. Its design needs to take into account the convenience and safety of the operator. It usually adopts a C-type structure to provide sufficient gripping space.

[0098] In one embodiment, the guide rail groove 421 is a T-shaped guide rail groove with an upper opening width greater than a lower opening width.

[0099] In application, the T-shaped guide groove 421 is designed to provide stable guide support without affecting the flexibility of the workbench. The lower opening is smaller than the upper opening, so that when the T-shaped guide groove 421 cooperates with the guide pressure plate on the quick positioning clamping fixture, the height direction can be limited, so that it can move along with the lifting and lowering of the guide pressure plate.

[0100] The working principle of the workpiece circulation exchange device is as follows:

[0101] The operator places the blank of the motor base 40 on the universal workpiece fixture 41 in the workpiece preparation area. The stopper 4111 and the auxiliary positioning device 413 on the fixture plate 411 ensure that the base is accurately positioned, and the auxiliary clamping device 412 is used to firmly fix the motor base 40. After that, the universal workpiece fixture 41 is assembled on the workpiece circulation exchange workbench 42 to form a motor base assembly. In the entire processing process, the motor base assembly is circulated as a whole.

[0102] like Fig.16 As shown, an intelligent rail trolley provided in an embodiment of the present application includes an exchange telescopic frame 7, a lifting device 8 and a trolley slide 9, the lifting device 8 is arranged on the surface of the trolley slide 9, and at least two exchange telescopic frames 7 are arranged on the top of the lifting device 8;

[0103] The exchange telescopic rack 7 is configured such that at least one is used to retrieve the workpiece of the target processing station into the exchange telescopic rack 7, and at least another is used to transfer the workpiece in the exchange telescopic rack 7 to the target processing station;

[0104] The lifting device 8 is configured to drive the exchange telescopic frame 7 to perform lifting and lowering movements;

[0105] The trolley slide plate 9 is configured to be slidably matched with the track and can move on the track along a first direction or a second direction, the first direction being opposite to the second direction.

[0106] In application, there are at least two exchange telescopic racks 7, and there may be more than two, for example, three or four can be set as needed. When two exchange telescopic racks 7 are set on the top of the lifting device 8, one is responsible for receiving the workpieces that have been processed and bringing them back to the intelligent rail trolley, and the other is responsible for sending the workpieces to be processed to the next processing station. The lifting device 8 can drive the entire exchange telescopic rack 7 to perform lifting and lowering movements so as to accurately dock processing equipment at different heights. Four L-shaped heavy-duty slider mounting seats 94 are provided at the bottom of the trolley slide 9. These sliders cooperate with the guide rails on the track to ensure that the trolley can move smoothly on the track in the first direction (forward) or the second direction (reverse), thereby realizing the transfer of workpieces between different processing stations.

[0107] The intelligent rail trolley of the embodiment of the present application adopts an exchange telescopic frame with a double-station design, and the trolley slide cooperates with the track to realize the reciprocating motion of the trolley along the production line, and can complete the flow of workpieces between various stations. The intelligent rail trolley is provided with a lifting device, which can lift the workpiece according to the height of different stations, so as to facilitate smooth docking with the station and realize the picking and placing of the workpiece. The intelligent rail trolley can realize the automatic and orderly flow of workpieces between the upper and lower material channels and various processing stations, which improves the automation level of the production line and improves the processing efficiency.

[0108] like Fig.17As shown, in one embodiment, the exchange telescopic frame 7 includes an inlet and outlet main support 71 and an inlet and outlet exchange support 72, the inlet and outlet exchange support 72 is slidably and telescopically arranged in the inlet and outlet main support 71, main support rollers 711 are arranged on both sides of the inlet and outlet main support 71 along the workpiece transmission direction, exchange support rollers 721 are arranged on both sides of the inlet and outlet exchange support 72 along the workpiece transmission direction, and the exchange support rollers 721 are transmission-connected to a driving assembly 722;

[0109] The main support roller conveyor 711 is configured to move synchronously with the exchange support roller conveyor 721 under the drive of the driving assembly 722 to transfer the workpieces located on the main support roller conveyor 711 and the exchange support roller conveyor 721;

[0110] The in-and-out material exchange bracket 72 is configured to extend from the in-and-out material main bracket 71 to achieve the transfer of the workpiece from the exchange telescopic bracket to the target processing station; and retract into the in-and-out material main bracket 71 to achieve the transfer of the workpiece from the target processing station to the exchange telescopic bracket.

[0111] In application, the main inlet and outlet bracket 71 and the inlet and outlet exchange bracket 72 are made of high-strength steel and are precisely processed to ensure that the surface flatness and roughness meet the requirements. The power output of the drive component 722 is transmitted to the exchange bracket roller 721 through the chain transmission system, thereby driving the main bracket roller 711 to move synchronously. This synchronization mechanism is precisely controlled by the control system to ensure that the workpiece remains stable during the transmission process. The telescopic movement of the inlet and outlet exchange bracket 72 is driven by a hydraulic cylinder, and precise positioning and stable movement are achieved through linear guides and guide sliders.

[0112] In application, a main bracket fixing plate 715 for connecting to the intelligent rail trolley is provided at the bottom of the inlet and outlet main bracket 71. An exchange bracket fixing plate 730 for connecting to the intelligent rail trolley is provided at the bottom of the inlet and outlet exchange bracket 72.

[0113] In one embodiment, Fig.18 As shown, the main support roller conveyor 711 includes a main support roller 7111, a main support sprocket 7112 located outside the main support roller 7111, and a main support chain for transmitting and connecting adjacent main support sprockets 7112. The main support roller 7111 is coaxially connected to the main support sprocket 7112, and the main support rollers 7111 on both sides are coaxially connected through the main support long axis roller 714.

[0114] In application, the main support roller 7111 is made of wear-resistant material, and the outer diameter and width are optimized according to the actual workpiece size to ensure sufficient load-bearing capacity and operational stability. The main support sprocket 7112 is installed on the outside of the roller to form a closed transmission system with the main support chain. The rollers of each set of rollers are installed at equal distances and heights between the support baffles, and are equipped with double-row sprockets. Adjacent sprockets transmit kinetic energy through the chain, and the two sets of rollers are connected through the long-axis rollers. The chain is made of high-strength alloy steel with good tensile strength and corrosion resistance. The main support long-axis roller 714 connects the main support rollers 7111 on both sides coaxially to ensure that the rollers on both sides rotate synchronously to avoid offset or jamming caused by uneven force on one side. The mounting surface of the entire main support roller 711 is finely polished to ensure smoothness and fit when in contact with the workpiece, reducing wear and friction losses.

[0115] In application, the main support sprocket 7112 adopts a double-row sprocket structure, so that every two adjacent main support sprockets 7112 are connected by a main support chain transmission. For example, the first main support sprocket and the second main support sprocket are connected by a main support chain transmission, and the second main support sprocket and the third main support sprocket are connected by another main support chain transmission.

[0116] In one embodiment, Fig.19 As shown, the exchange bracket roller conveyor 721 includes an exchange bracket roller 7211, an exchange bracket sprocket 7212 located on the inner side of the exchange bracket roller 7211, and an exchange bracket chain for transmitting and connecting adjacent exchange bracket sprockets 7212. The exchange bracket roller 7211 is coaxially connected with the exchange bracket sprocket 7212, and the exchange bracket rollers 7211 on both sides are coaxially connected through the exchange bracket long axis roller 723.

[0117] In application, the exchange bracket sprocket 7212 also adopts a double-row sprocket structure, so that every two adjacent exchange bracket sprockets 7212 are connected by an exchange bracket chain transmission. For example, the first exchange bracket sprocket and the second exchange bracket sprocket are connected by an exchange bracket chain transmission, and the second exchange bracket sprocket and the third exchange bracket sprocket are connected by another exchange bracket chain transmission.

[0118] In one embodiment, Fig. 20 and 21 As shown, the driving assembly 722 includes a driving motor 7221, an axial extension sprocket 7222 and a chain 7223. The axial extension sprocket 7222 is coaxially fixedly connected to the motor shaft of the driving motor 7221, and the axial extension sprocket 7222 is transmission-connected to the exchange bracket sprocket 7212 through the chain 7223.

[0119] In application, the drive motor 7221 uses an efficient and energy-saving servo motor, which has the characteristics of fast response speed and high positioning accuracy, and is suitable for occasions of frequent start and stop and high-speed operation. An extension sprocket 7222 is installed on the motor shaft, and the sprocket is connected to the motor shaft through a keyway to ensure that the two rotate synchronously. The chain 7223 is made of high-strength alloy steel, which has good tensile strength and corrosion resistance, ensuring reliability and durability under long-term use. The drive component 722 is connected to the exchange bracket sprocket 7212 through the chain 7223, realizing efficient driving force transmission and ensuring precise control of the exchange bracket roller 721. The connection between the motor and the sprocket is also equipped with a protective cover to prevent external impurities from entering and affecting the transmission efficiency.

[0120] In one embodiment, a linear guide rail 725 is provided at the bottom of the inlet and outlet exchange bracket 72 along the telescopic direction, and the inlet and outlet main bracket 71 is provided with an exchange bracket driving hydraulic cylinder 712 below the inlet and outlet exchange bracket 72 for driving the inlet and outlet main bracket 71 to extend or retract into the inlet and outlet main bracket 71, and a guide rail slider 713 that slides with the linear guide rail 725 under the drive of the exchange bracket driving hydraulic cylinder 712.

[0121] In application, the linear guide 725 adopts a high-precision ball guide with the characteristics of high rigidity and low friction, ensuring the stability and accuracy of the in-and-out material exchange bracket 72 during the extension and retraction process. The guide slider 713 is installed at the bottom of the in-and-out material main bracket 71, and closely cooperates with the linear guide 725 to ensure gapless movement during the sliding process. The exchange bracket drive hydraulic cylinder 712 uses a high-performance hydraulic cylinder with the characteristics of large thrust and fast response, which can complete the extension and retraction of the in-and-out material exchange bracket 72 in a short time. The end of the piston rod of the hydraulic cylinder is fixedly connected to the guide slider 713 to ensure the effective transmission of the driving force. In addition, the hydraulic system can also be equipped with a pressure sensor and a limit switch to ensure the safety and reliability of the system.

[0122] In one embodiment, the inlet and outlet material exchange bracket 72 is used to extend out of the front end of the inlet and outlet material exchange bracket 72 and is provided with a front end oil pressure buffer 729 .

[0123] In application, the front hydraulic buffer 729 is installed at the front end of the feed-in and feed-out exchange bracket 72. It adopts a double-acting hydraulic buffer design with an adjustable damping coefficient, which can be adjusted according to different workpiece weights and speeds. The buffer is filled with high-quality hydraulic oil to ensure a stable buffering effect. The outer shell of the buffer is made of high-strength aluminum alloy material, which not only reduces the weight but also enhances the structural strength. The front hydraulic buffer 729 plays a buffering role when the feed-in and feed-out exchange bracket 72 is extended, effectively reducing the impact force and protecting the equipment and workpieces from damage. Especially in the case of high-speed operation or emergency stop, it can significantly reduce the possibility of accidents and ensure the long-term reliable operation of the system.

[0124] In one embodiment, a rear end hydraulic buffer 717 is provided at a corresponding position of the rear ends of the inlet and outlet main bracket 71 and the inlet and outlet exchange bracket 72 .

[0125] In application, the rear hydraulic buffer 717 is installed at the corresponding position of the rear end of the inlet and outlet main bracket 71 and the inlet and outlet exchange bracket 72. The rear hydraulic buffer 717 plays a buffering role when the inlet and outlet exchange bracket 72 is retracted, preventing the strong impact caused by sudden stop and protecting the integrity of the equipment structure. Especially in the case of frequent operation, it can significantly extend the service life of the equipment and ensure the long-term reliable operation of the system.

[0126] In one embodiment, a workpiece pushing hydraulic cylinder 726 is provided between the inlet and outlet material exchange bracket 72 and the exchange bracket roller 721 , and a workpiece locking assembly is provided at the piston end of the workpiece pushing hydraulic cylinder 726 .

[0127] In application, the workpiece ejection hydraulic cylinder 726 is installed inside the in-and-out material exchange bracket 72, and its piston rod is connected to the hydraulic cylinder interface 731 at the bottom of the in-and-out material exchange bracket 72. The position close to the exchange bracket roller 721 ensures the accuracy and strength of the workpiece ejection. The hydraulic cylinder uses a high-performance hydraulic cylinder with the characteristics of large thrust and fast response, and can complete the workpiece ejection action in a short time. A workpiece locking assembly is installed at the end of the piston rod of the hydraulic cylinder, which includes a plane rotating cylinder 727 and a locking block 728. When the hydraulic cylinder piston rod is extended, the locking block 728 is driven by the plane rotating cylinder 727 to rotate to the first angle to lock the workpiece; when the hydraulic cylinder piston rod is retracted, the locking block 728 rotates to the second angle to release the workpiece. This design not only improves the reliability of workpiece fixation, but also simplifies the operation process, reduces manual intervention, and improves work efficiency.

[0128] In one embodiment, the workpiece locking assembly includes a planar rotary cylinder 727 and a locking block 728 connected to the planar rotary cylinder 727;

[0129] The locking block 728 is configured to rotate to a first angle under the drive of the planar rotating cylinder 727 to lock the workpiece, or to rotate to a second angle under the drive of the planar rotating cylinder 727 to release the workpiece.

[0130] In one embodiment, the inlet and outlet material exchange bracket 72 is provided with an inner baffle plate 724 on the inner side of the exchange bracket roller conveyor 721, and the top surface is higher than the surface of the exchange bracket roller conveyor 721. The inlet and outlet material main bracket 71 is provided with an outer baffle plate 716 on the outer side of the main bracket roller conveyor 711, and the workpiece is confined between the inner baffle plate 724 and the outer baffle plate 716.

[0131] In application, the inner baffle 724 and the outer baffle 716 are respectively installed at the corresponding positions of the inlet and outlet exchange bracket 72 and the inlet and outlet main bracket 71. They are made of high-strength steel and the surface is rust-proofed to ensure durability for long-term use. The height of the inner baffle 724 is slightly higher than the surface of the exchange bracket roller 721, while the height of the outer baffle 716 is slightly higher than the surface of the main bracket roller 711, forming a closed space, which effectively prevents the workpiece from sliding or tipping laterally during the transmission process. The top edge of the baffle is rounded to avoid scratching the workpiece surface. The limited space formed by the inner baffle 724 and the outer baffle 716 ensures the stable transmission and guidance of the workpiece.

[0132] In one embodiment, Fig. 22 As shown, the lifting device 8 includes an outer frame 82 and a lifting component 81 arranged on the outer frame 82 and capable of lifting and lowering relative to the outer frame 82. The bottom of the outer frame 82 is fixed to the surface of the trolley slide 9, and a sensor component 83 is provided on the outer frame 82.

[0133] In use, the lifting device 8 is composed of an outer frame 82 and a lifting assembly 81 that can perform lifting and lowering movements relative to the outer frame. The outer frame 82 is fixed to the surface of the trolley skateboard 9 by bolts, providing a solid foundation for the lifting assembly. The outer frame 82 is welded from high-quality hollow square steel profiles and thick steel plates. The use of high-strength steel ensures that the frame has sufficient rigidity and load-bearing capacity while reducing the overall weight. Precision welding technology is used during the welding process to ensure the strength and flatness of the joints and avoid stress concentration points. The outer frame 82 is an overall rectangular structure, and the four corners are reinforced with ribs to enhance the overall stability and deformation resistance of the structure. Partitions are provided inside the frame to support and fix the various components of the lifting assembly 81, such as motors, reducers, worm gear mechanisms, etc.

[0134] In one embodiment, Fig.23As shown, the lifting assembly 81 includes a lifting panel 811, a lifting motor 812, a first reducer 813, a bevel gear box 814, a transmission shaft 815, a worm gear mechanism 817 and a ball screw mechanism 816.

The top end of the screw of the ball screw mechanism 816 is connected to the lifting panel 811, the output end of the lifting motor 812 is connected to the input end of the first reducer 813, the output end of the first reducer 813 is connected to the input end of the bevel gear box 814, the output end of the bevel gear box 814 is connected to one end of the transmission shaft 815, the other end of the transmission shaft 815 is connected to the input end of the worm gear mechanism 817, and the worm of the worm gear mechanism 817 is engaged with the nut of the ball screw mechanism 816.

[0135] In application, the lifting motor 812 is mounted on the outer frame 82, and its output end is connected to the input end of the first reducer 813 to reduce the rotation speed and increase the torque. The output end of the first reducer 813 is connected to the input end of the bevel gearbox 814, and the bevel gearbox 814 changes the power transmission direction so that the originally vertical power output becomes horizontal. The output end of the bevel gearbox 814 is connected to one end of the transmission shaft 815, and the other end of the transmission shaft 815 is connected to the input end of the worm gear mechanism 817. The worm inside the worm gear mechanism 817 is engaged with the nut of the ball screw mechanism 816. When the worm rotates, the screw in the ball screw mechanism 816 is driven to rotate. The ball screw mechanism 816 is fixed on the outer frame 82, and the top end of its screw is connected to the lifting panel 811. As the screw rotates, the lifting panel 811 can be raised and lowered.

[0136] In one embodiment, the lifting assembly 81 also includes a linear bearing 818 and a guide shaft 819. The top of the guide shaft 819 is fixedly connected to the lifting assembly 81. The bottom of the guide shaft 819 is provided with an axis baffle 820. The guide shaft 819 is slidably set in the linear bearing 818, and the linear bearing 818 is fixed to the outer frame 82.

[0137] In application, in order to ensure the stability and accuracy of the lifting process, guide shafts 819 are installed at the four corners of the lifting panel 811, and these guide shafts are slidably set in linear bearings 818, and linear bearings 818 are fixed on the peripheral frame 82. A shaft baffle 820 is provided at the bottom of the guide shaft 819, which is used as a mechanical limit and also as a trigger element of the side limit switch 833 and the bottom limit switch 832 to detect the position of the lifting panel 811 and send corresponding signals to the control system.

[0138] In one embodiment, the sensor assembly 83 includes at least one of a side limit switch 833, a bottom limit switch 832, and a trolley position detection switch 831;

[0139] The side limit switch 833 is arranged on one side of the shaft stopper 820, the bottom limit switch 832 is arranged below the shaft stopper 820, and the trolley position detection switch 831 is arranged on the peripheral frame 82 at a position corresponding to the track marking point;

[0140] The side limit switch 833 is configured to be triggered by the shaft stopper 820 and send the lifting panel 811 rising and falling position signals and speed control signals after being triggered;

[0141] The bottom limit switch 832 is configured to be triggered by the shaft stopper 820 and send a reference point arrival signal after being triggered;

[0142] The trolley position detection switch 831 is configured to sense track marking points and send a trolley position signal when triggered.

[0143] In application, when the lifting panel 811 is located at the corresponding position of the side limit switch 833, the connection with the side limit switch 833 is realized through the contact point. At this time, the shaft baffle 820 will trigger the side limit switch 833, thereby sending the lifting panel 811 rising and falling position signals and speed control signals after triggering. When the lifting panel 811 is completely lowered to the lowest position, the shaft baffle 820 will trigger the bottom limit switch 832. At this time, the system receives the confirmation information of "reaching the reference point", and can perform the next operation or reset to prepare for the next lifting cycle. The trolley position detection switch 831 senses specific marking points on the track through non-contact sensing methods (such as photoelectric sensors or magnetic sensors), and sends the current trolley position signal to the central control system after triggering. This allows the intelligent track trolley to accurately locate each processing station on the preset path, ensuring that the workpiece can be loaded and unloaded and processed in the correct position. At the same time, the trolley position detection switch 831 can also work in conjunction with other control systems to achieve real-time monitoring and optimized scheduling of the entire production line, further improving production efficiency and product quality.

[0144] In application, a workpiece detection switch 84 is also provided on the lifting panel 811 for detecting the workpiece on the exchange telescopic frame 7 .

[0145] The embodiment of the present application not only provides a powerful driving force and a smooth and reliable lifting function, but also realizes high-efficiency conversion and high-precision positioning through a multi-stage transmission system. At the same time, the application of built-in sensors enhances the self-protection ability and reliability of the system, simplifies maintenance procedures, and reduces long-term operating costs. The modular design is also easy to integrate with other automation systems, promoting the intelligent upgrade of the entire production line.

[0146] In one embodiment, Fig.24As shown, the trolley skateboard 9 includes a skateboard body 93, a travel drive motor 91, a second reducer 92 and a driving gear 95. The travel drive motor 91 and the second reducer 92 are arranged on the surface of the skateboard body 93. The output end of the travel drive motor 91 is connected to the input end of the second reducer 92. The output end of the second reducer 92 passes through the skateboard body 93 and is coaxially connected to the driving gear 95 under the skateboard body 93. The driving gear 95 is meshed with a rack arranged on the track along the length direction of the track.

[0147] In application, the skateboard body 93 is made of high-strength steel, has sufficient rigidity and load-bearing capacity, and in order to reduce weight, reasonable structural optimization is adopted in the design. Four L-shaped heavy-load slider mounting seats 94 are provided on the lower surface of the skateboard body 93, and a trolley slider is installed on the lower surface of each mounting seat. These sliders cooperate with the two parallel heavy-load linear guides on the track to ensure the smooth sliding of the intelligent track trolley on the track.

[0148] In one embodiment, a slider mounting seat 94 is provided on the lower surface of the skateboard body 93, and a trolley slider is installed on the lower surface of the slider mounting seat 94. The trolley slider is used to slide with a guide rail arranged on the track along the length direction of the track. A downwardly protruding positioning step 941 is provided on the inner side of the lower surface of the slider mounting seat 94, and the positioning step 941 is limitedly matched with the inner side surface of the slider along the width direction of the track.

[0149] In application, a downwardly protruding positioning step 941 is provided on the inner side of the lower surface of the slider mounting seat 94, so that the inner side of the slider can limit the intelligent track trolley in the width direction of the track, so as to offset the force toward the outside of the track generated by the interaction between the rack and the drive gear of the track.

[0150] In one embodiment, Fig.25 As shown, a lubrication gear 98 is provided on one side of the driving gear 95 , and the lubrication gear 98 is meshed with the driving gear 95 .

[0151] In application, in order to ensure the long-term stable operation of the driving system, a lubrication gear 98 is configured on one side of the driving gear 95, and the two are kept in meshing to provide continuous lubrication for the driving gear 95, reduce wear and extend the service life.

[0152] In one embodiment, Fig.26 As shown, the travel drive motor 91 is installed at one corner of the trolley slide 9, and two waist-shaped holes 911 are respectively provided on both sides of the motor base, which are used to adjust the position of the travel drive motor 91 when the travel drive motor 91 is installed, so that the driving gear 95 of the travel drive motor 91 can mesh with the rack on the track. After the motor base is installed in place and meshed with the rack, it is tightened by the motor base tightening plate 96 and pre-tightened by the motor base tightening bolts 97.

[0153] The working principle of the intelligent rail car is as follows:

[0154] When the workpiece is transferred to the set position on the exchange telescopic frame of the intelligent rail trolley along with the workpiece circulation exchange workbench, the plane rotary cylinder 727 is actuated to make the locking block 728 at the front end engage in the feeding and unloading handle of the workpiece circulation exchange workbench to ensure that the workpiece is firmly fixed. Subsequently, the intelligent rail trolley carries the workpiece to the loading point of a certain process on the processing line. In this process, the travel drive motor 91 drives the drive gear 95 to engage with the track rack through the second reducer 92 to achieve smooth travel of the trolley. After reaching the specified position, the lifting motor 812 in the lifting assembly 81 is started, and the power output direction is changed through the first reducer 813 and the bevel gear box 814, and is transmitted to the worm gear mechanism 817 via the transmission shaft 815, and finally drives the ball screw mechanism 816 to rotate, so that the screw moves up and down, and then pushes the lifting panel 811 to rise to an appropriate height to dock with the target processing station. At the same time, the exchange bracket driving hydraulic cylinder 712 and the driving motor 7221 cooperate to push out the in-and-out exchange bracket 72 and the workpiece circulation exchange worktable, and move them to the rapid positioning clamping fixture in the equipment processing area. When the in-and-out exchange bracket 72 is pushed into place, the workpiece pushing hydraulic cylinder 726 at its upper end starts to move, pushing out the workpiece circulation exchange worktable for a second time, so that the workpiece enters the rapid positioning clamping fixture in the equipment processing area, and completes precise positioning. Then, the plane rotating cylinder 727 rotates again, so that the locking block 728 releases the feeding and unloading handle of the workpiece circulation exchange worktable, allowing the exchange telescopic rack to reset and prepare to receive the next workpiece. When the above-mentioned mechanism is taking materials, the relevant actions are inverted: that is, when it is necessary to take out the processed workpiece from the processing area, the planar rotating cylinder 727 is first actuated to make the locking block 728 re-engage the feeding and taking handle of the workpiece circulation exchange worktable, and the exchange bracket driving hydraulic cylinder 712 and the driving motor 7221 cooperate to pull the workpiece circulation exchange worktable and the in-and-out material exchange bracket 72 back to the exchange telescopic bracket, and finally the planar rotating cylinder 727 rotates again to release the feeding and taking handle, completing a complete workpiece transmission cycle.

[0155] During the whole process, the workpiece detection switch 84 and the sensor assembly 83 (including the side limit switch 833, the bottom limit switch 832 and the trolley position detection switch 831) monitor the position and status of the intelligent rail trolley in real time, and provide feedback to the central control system CCS to ensure that each action can be executed accurately, thereby improving the automation level and reliability of the system.
