[0002] In the manufacturing process of automobile motors, engines and other rotating mechanical parts, the machining and assembly of the rotor are one of the key processes. Among them, accurately and reliably press-fitting the shaft sleeve into the rotor center hole is the core step to realize the stable connection of the rotor and the transmission shaft. This process usually involves interference fit, which requires heating the rotor to expand it and applying precise axial pressure to the shaft sleeve to ensure that the assembled components have sufficient connection strength, concentricity, and avoid damage to the parts during the press-in process.
[0003] At present, the industry uses step-by-step or single-function devices when performing such press-fitting operations. The common production mode is: first, the operator or simple robot places the rotor in the heating station to heat the shaft sleeve or the rotor; then, the heated parts are transferred to an independent press-fitting machine for press-fitting. This discrete process layout has the following significant defects: 1. Low production efficiency, the workpiece needs to be transported, positioned and waited between multiple independent devices or stations, the production rhythm is long, and it is difficult to adapt to the high rhythm requirements of automatic assembly line; 2. Poor positioning accuracy and consistency, multiple workpiece transfers can easily cause cumulative positioning errors, affecting the final press-fitting concentricity, there are many manual intervention links, and the product quality stability depends on the experience of the operator, and consistency is difficult to guarantee; 3.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0020] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.
[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] like Figures 1-17 As shown, this application relates to a split-type pressing device. For example... Figures 1-5 As shown, the split-type pressing equipment includes: a housing 1; the housing 1 serves as the external support structure for the entire machine, supporting core components such as the partition plate 2, multi-degree-of-freedom loading and unloading device, heating device, linear module 5, pressing mechanism, and counterweight transmission device 8. It provides a stable and unified installation benchmark for each functional module; simultaneously, it improves the overall operational stability and safety of the equipment.
[0023] It should be noted that the shell 1 is usually made of welded steel plates or assembled from profiles, which has good rigidity and vibration resistance.
[0024] A partition plate 2 is horizontally disposed within the housing 1 to divide the inner cavity of the housing 1 into a first chamber 210 and a second chamber 220. The partition plate 2 physically divides the internal space of the housing 1 into the upper first chamber 210 and the lower second chamber 220. This enables spatial isolation of functional modules, preventing interference from heat, vibration, and pressure impact. Simultaneously, the upper and lower chambers can respectively house light-load precision mechanisms and heavy-load force transmission mechanisms, conforming to structural mechanics principles. Furthermore, it facilitates maintenance, repair, and modular expansion.
[0025] For example, the first chamber 210 can be used to arrange the main process units such as picking, heating, conveying, and pressing, while the second chamber 220 can be used to arrange the power and transmission units, such as the motor and hydraulic source of the gravity transmission device 8.
[0026] A multi-degree-of-freedom (DOF) automotive rotor handling device 3 is vertically mounted in the first chamber 210 of the housing 1 along a first direction. The robot system, installed in the first chamber 210 and positioned along the first direction, can be a multi-joint robot (six-axis) or a high-precision gantry-type manipulator, possessing multiple degrees of freedom to flexibly grasp and place rotors. It can adapt to automotive rotors of different models, sizes, and weights, allowing for rapid product switching by changing the gripper or reprogramming, meeting flexible production needs. Simultaneously, it ensures precise positioning, accurately placing the rotor at the workstations of the rotary heating device 4 and the rotor bushing pre-loading device 6, laying the foundation for subsequent processes. Furthermore, it achieves full automation, replacing manual handling and enabling automatic connection of the production process, resulting in high efficiency and good consistency. Here, the first direction refers to the horizontal direction, or the X-axis direction in a three-coordinate system.
[0027] A rotary heating device 4 is connected to the partition plate 2 and is arranged adjacent to the multi-degree-of-freedom automotive rotor placement and removal device 3. The rotary heating device 4 is fixed to the partition plate 2 and positioned near the multi-degree-of-freedom placement and removal device, allowing for rotation and lifting heating of the rotor after it has been placed. The heating method can be induction heating, resistance heating, or hot air heating. Heating causes thermal expansion of the rotor's inner bore, improving the smoothness of the bushing press-fit assembly.
[0028] A linear module 5 is disposed on the partition plate 2 along the second direction and adjacent to the rotary heating device 4. The linear module 5, disposed along the second direction, carries the rotor bushing pre-loading device 6 and enables its precise linear movement between different workstations. This allows for automatic docking between workstations, ensuring the coaxiality of the bushing and rotor; simultaneously, the high precision of linear motion facilitates accurate positioning before pressing; and it can also be linked with a control system to achieve continuous operation with controllable cycle time. Here, the second direction refers to the front-to-back direction, or the Y-axis direction in a three-coordinate system.
[0029] The rotor bushing pre-loading device 6 is mounted on the slide table 510 of the linear module 5. It is a tooling or mechanism installed on the slide table 510 of the linear module 5, and its function is to reciprocate to receive the rotor from the pick-and-place device, and place the bushing (usually provided by another six-axis robot) into the rotor hole in a guiding and preliminary positioning manner. This achieves preliminary alignment by using tapered guide pins or a self-aligning mechanism to ensure that the bushing is basically concentric with the rotor hole before pressing, preventing jamming or scratching due to misalignment at the beginning of pressing. Simultaneously, it decomposes the process, separating the fine action of "alignment" from the high-pressure pressing process, which is then completed by a dedicated mechanism in a low-pressure environment, improving the success rate and quality reliability of pressing. Furthermore, integrated into the conveyor line as part of the slide table 510, it moves with the slide table 510, realizing modular integration of the workstation functions.
[0030] The pressing device 7 is vertically mounted on the upper surface of the partition plate 2 and is arranged adjacent to the rotor bushing pre-filling device 6 above the linear module 5. The pressing device 7, vertically positioned above the partition plate 2, applies downward pressing force to the rotor and bushing, and typically includes a servo pressure head 780, a pressure sensor, and a displacement detection assembly. It enables a controllable pressing process, allowing real-time monitoring of pressure and displacement; it is also suitable for high-precision pressing processes, preventing overpressure damage to the rotor. Here, "vertical direction" refers to the up-and-down direction, or the Z-axis direction in a three-coordinate system.
[0031] The counterweight transmission device 8 is vertically mounted on the lower surface of the partition plate 2, with its lifting output end co-centered with the pressing device 7. The counterweight transmission device 8 provides stable and predictable reverse support force through the counterweight structure. It can utilize gravity or counterweight to achieve smooth reaction force output, reducing energy consumption; simultaneously, it improves the stability and repeatability of the pressing process; and it achieves good centering effect.
[0032] The multi-degree-of-freedom automobile rotor pick-and-place device 3 places the rotor in a preset order onto the rotary heating device 4 and the rotor bushing pre-filling device 6 located on the linear module 5. The linear module 5 then transports the pre-filled rotor and bushing between the pressing device 7 and the counterweight transmission device 8. The pressing device 7 and the counterweight transmission device 8 act on the rotor and bushing respectively to press the bushing into the rotor.
[0033] Specifically, the working principle of this application is as follows: 1. The multi-degree-of-freedom automobile rotor picking and placing device 3 picks up the rotor in a preset sequence and places it to the designated device or workstation; Second, the rotor is first placed on the rotary heating device 4 and rotated to the lifting position. The first lifting component 430 lifts the rotor to the designated position of the heating component 440 so as to heat the inside and outside of the rotor evenly at the same time. 3. After heating is completed, the rotor is rotated out and then transferred by the multi-degree-of-freedom automobile rotor pick-and-place device 3 to the bushing pre-loading device on the linear module 5. IV. After the bushing is pre-filled, the linear module 5 will transport the rotor to the press-fitting station; 5. The pressing device 7 applies downward force, and the counterweight transmission device 8 provides upward reaction force, so that the bushing is precisely pressed into the rotor, completing the assembly.
[0034] As can be seen from the above description, this application achieves the following technical effects: In this embodiment, an integrated and optimized equipment structure is adopted. The multi-degree-of-freedom automotive rotor pick-and-place device 3 places the rotor in a preset order onto the rotary heating device 4 and the rotor bushing pre-loading device 6 located on the linear module 5. The linear module 5 transports the pre-loaded rotor and bushing between the pressing device 7 and the counterweight transmission device 8. The pressing device 7 and the counterweight transmission device 8 act on the rotor and bushing respectively to press the bushing into the rotor, achieving the purpose of automatic pressing of the bushing and rotor. This achieves the technical effects of improving production efficiency, positioning accuracy, consistency, and equipment integration. This addresses the significant drawbacks of traditional discrete process layouts: 1. Low production efficiency: workpieces need to be moved, positioned, and waited for between multiple independent devices or workstations, resulting in long production cycles and difficulty in adapting to the high-paced requirements of automated production lines; 2. Poor positioning accuracy and consistency: multiple workpiece transfers can easily lead to cumulative positioning errors, affecting the final pressing concentricity; there are many manual intervention steps, and product quality stability depends on the operator's experience, making consistency difficult to guarantee; 3. Low equipment integration and large footprint: dispersed heating devices, handling devices, and pressing equipment occupy a large amount of workshop space, and the coordination and control between them are complex, resulting in low production line flexibility.
[0035] Furthermore, the multi-degree-of-freedom automobile rotor loading and unloading device 3 includes: a plurality of support columns 310 spaced apart along the same direction; The base plate 320 is horizontally disposed on top of the plurality of support columns 310; A fixing plate 330 is vertically disposed on one side of the base plate 320; The first drive assembly 340 is horizontally disposed on one side of the fixed plate 330 and is used to drive the gripper 3120 to move horizontally. The first connecting plate 350 is perpendicularly connected to the output end of the first driving component 340; The second drive component 360 is vertically disposed on the first connecting plate 350 and is used to drive the gripper 3120 to move up and down. The second connecting plate 370 is connected to the output terminal of the second driving component 360; The third drive assembly 380 is horizontally disposed on the second connecting plate and is used to drive the gripper 3120 to move back and forth. The third connecting plate 390 is horizontally disposed at the output end of the third driving component 380; The fourth drive component 3100 is vertically disposed on one side of the third connecting plate 390, with its output end facing the ground, and is used to drive the gripper 3120 to rotate. The fifth drive component 3110 is horizontally connected to the output end of the fourth drive component 3100 and is used to drive the two grippers 3120 to move closer to or separate from each other. Two grippers 3120 are positioned opposite each other at the output end of the fifth drive assembly 3110; and Two sixth drive components 3130 are respectively horizontally arranged on the outside of the gripper 3120 for flipping the car rotor.
[0036] Specifically, such as Figures 10-13 As shown, this application relates to a multi-degree-of-freedom automobile rotor loading and unloading device 3. For example... Figures 10-12 As shown, the multi-degree-of-freedom automobile rotor loading and unloading device 3 includes: a plurality of support columns 310 spaced apart along the same direction; the plurality of support columns 310 spaced apart along the same direction form the load-bearing frame of the overall device; it can improve the overall rigidity and anti-deformation ability, and ensure the stability and repeatability of positioning during multi-degree-of-freedom motion.
[0037] The base plate 320 is horizontally disposed on top of several of the support columns 310; the base plate 320 is horizontally disposed on top of the support columns 310 and serves as the mounting reference surface for the upper mechanism; it can improve the consistency of device assembly and facilitate modular expansion and subsequent maintenance.
[0038] The fixing plate 330 is vertically set on one side of the base plate 320; the fixing plate 330 is vertically set on one side of the base plate 320 to form a vertical installation reference; it is beneficial to realize the orthogonal decoupling of lateral movement and vertical movement and improve the motion accuracy of the system.
[0039] The first drive assembly 340 is horizontally disposed on one side of the fixed plate 330 and is used to drive the gripper 3120 to move horizontally; the first drive assembly 340 drives the gripper 3120 to move in the horizontal direction; it can realize the lateral switching between pick-up and put-down stations. The horizontal direction can also be the X-axis direction in a three-coordinate system.
[0040] It should be noted that the first drive component 340 can be a servo motor + linear module 5, as long as it can achieve horizontal movement, and no limitation is made in this application.
[0041] The first connecting plate 350 is vertically connected to the output end of the first driving component 340; it can serve as a mounting carrier for the vertical motion module, thereby enabling force transmission between different motion units.
[0042] The second drive assembly 360 is vertically mounted on the first connecting plate 350 and is used to drive the gripper 3120 to move up and down. It can control the gripper 3120 to move up and down, thereby realizing the gripping, lifting and placing of the rotor.

It can drive the gripper 3120 to move in the back and forth direction, thereby achieving fine adjustment of the clamping position. The back and forth direction can also be the Y-axis direction in a three-coordinate system.
[0045] The third connecting plate 390 is horizontally positioned at the output end of the third drive component 380; it can provide an installation reference for the rotary drive component 410, thereby ensuring the stability of the rotation axis.
[0046] The fourth drive component 3100 is vertically disposed on one side of the third connecting plate 390, with its output end facing the ground, and is used to drive the gripper 3120 to rotate; it can drive the gripper 3120 and the car rotor to rotate around the vertical axis, thereby achieving rotor angle adjustment and direction alignment.
[0047] The fifth drive component 3110 is horizontally connected to the output end of the fourth drive component 3100 and is used to drive the two grippers 3120 to move closer to or separate from each other; it can control the two grippers 3120 to move closer to or separate from each other, thereby realizing reliable clamping or release of the rotor.
[0048] Two grippers 3120 are positioned opposite each other at the output end of the fifth drive assembly 3110; they can symmetrically grip the rotor, thereby ensuring a balanced force.
[0049] Two sixth drive components 3130 are horizontally arranged on the outer side of the gripper 3120, respectively, for flipping the automobile rotor. This enables the gripper 3120 to flip around its own axis, thereby achieving the switching of the rotor's front and back sides or attitude flipping, and thus realizing complex attitude adjustments that are difficult to achieve with traditional pick-and-place mechanisms, significantly improving automation flexibility.
[0050] As can be seen from the above description, this application achieves the following technical effects: In this embodiment, multiple drive components are combined to drive the gripper 3120. By integrating multiple drive components, the gripper 3120 achieves multi-degree-of-freedom movement, thereby reducing labor intensity, improving work efficiency, and adapting to various usage scenarios. This solves the problems of existing technologies that use manual handling, which is not only labor-intensive and inefficient, but also difficult to ensure consistency and accuracy of operation. Furthermore, direct human contact can easily lead to rotor surface contamination and damage, as well as safety hazards. Additionally, traditional robotic arms / simple grippers have problems such as low automation, easy product damage, and insufficient reliability of positioning and assembly accuracy.
[0051] Furthermore, a third sliding component 3140, parallel to the first driving component 340, is provided on the fixed plate 330 near its top side. The sliding end of the third sliding component 3140 is connected to the first connecting plate 350. It is understood that the third sliding component 3140 is preferably a linear guide, a slider assembly, or a linear slide table 510, and its orientation is parallel to the movement direction of the first driving component 340. It is connected to the first connecting plate 350 through its sliding end, thereby guiding and constraining the movement trajectory of the first connecting plate 350 when the first driving component 340 drives the first connecting plate 350 to move horizontally. This achieves dual guidance and support for the first connecting plate 350, avoiding swaying caused by load eccentricity or multi-stage driving superposition; simultaneously, it reduces the single-point force on the first driving component 340, extending its service life; and it also improves the straightness and repeatability of the gripper 3120 during horizontal movement.
[0052] Furthermore, a first U-shaped plate 3150 is provided on the top of the fixing plate 330, and a first cable chain 3160 is provided within the first U-shaped plate 3150. It is understood that the first U-shaped plate 3150 forms a semi-enclosed or fully enclosed cable chain mounting cavity, and the first cable chain 3160 is fixed to the fixing plate 330 to accommodate and guide the cables, air pipes, or signal lines of the first drive assembly 340 and its associated components. This prevents the cables from becoming entangled, stretched, or worn during the horizontal reciprocating motion of the first drive assembly 340.
[0053] Furthermore, a second U-shaped plate 3170 is also provided on one side of the first connecting plate 350, and a second cable chain 3180 is also provided inside the second U-shaped plate 3170. It can be understood that the second U-shaped plate 3170 and the second cable chain 3180 mainly serve the vertical movement of the second drive assembly 360, and are used to synchronously pull and protect the cable as it rises and falls with the second connecting plate 370. This can prevent the cable from sagging or bending due to its own weight during vertical movement; it can also ensure the stability of the power supply and signal of the second drive assembly 360 under high-frequency lifting conditions.
[0054] Furthermore, a seventh drive assembly 3190 is respectively provided on both sides of the fifth drive assembly 3110 and on the side away from the gripper 3120. The seventh drive assembly 3190 is used to press down on the vehicle rotor. It can be understood that the seventh drive assembly 3190 may be, but is not limited to, a cylinder, an electric cylinder, or a servo clamping mechanism, and is located outside the gripper 3120 to apply vertical or inclined downward pressure to the rotor; it can ensure the effect of contact between adjacent vehicle rotors.
[0055] Furthermore, a buffer pad 3200 is also provided on the inner wall of the gripper 3120. It is understood that the buffer pad 3200 can be made of, but is not limited to, rubber, polyurethane, silicone, or composite elastic materials, and is fixed to the inner wall area of the gripper 3120 in contact with the rotor. This effectively buffers the impact force during clamping, preventing scratches or indentations on the rotor surface; at the same time, it increases the clamping friction coefficient, reducing the risk of rotor slippage.
[0056] Furthermore, the first drive assembly 340 is also provided with a first limit sensor 3210. It can be understood that the first limit sensor 3210 is used to detect the end point of the stroke of the first drive assembly 340, thereby preventing mechanical impact caused by overtravel of horizontal movement.
[0057] Furthermore, the second drive assembly 360 is also provided with a second limit sensor 3220. It is understood that the second limit sensor 3220 is used to monitor the extreme positions of the lifting height, thereby preventing the gripper 3120 from pressing down excessively or lifting insufficiently.
[0058] Furthermore, the third drive assembly 380 is also provided with a third limit sensor 3230. It can be understood that the third limit sensor 3230 is used to limit the range of movement in the forward and backward directions, thereby ensuring that the gripper 3120 always operates within the safe working area.
[0059] Of course, to ensure the normal operation of the drive components, other drive components are also equipped with limit sensors, as should be known to those skilled in the art.
[0060] like Figure 13As shown, a plurality of reinforcing ribs 3240 are provided between the base plate 320 and the fixing plate 330, on the side away from the first driving assembly 340. It can be understood that the reinforcing ribs 3240 are preferably triangular or oblique plate-shaped structures, used to connect the base plate 320 and the fixing plate 330 to form a stable spatial support system.
[0061] This application also has the following beneficial effects: 1. This application features highly integrated and flexible production, combining the functions of gantry-type movement, truss-type lifting, articulated rotation, and special tooling into a single, highly integrated robot unit. Compared to general industrial robots, it has a more compact structure and has been deeply optimized for rotor handling scenarios, potentially resulting in higher efficiency and rigidity.
[0062] 2. This application significantly improves production efficiency and automation level. Through multi-degree-of-freedom coordinated motion, it can complete a full set of actions including "precise grasping, lifting, transferring, aerial attitude adjustment, precise placement, and flipping when necessary".
[0063] 3. This application can guarantee product quality and consistency. Full servo / high-precision control eliminates random errors and the risk of bumps and knocks caused by manual handling. Precise angle control and flipping function ensure the positioning accuracy of the rotor in subsequent workstations, improving the quality consistency of the final product.
[0064] 4. It reduces labor costs and labor intensity, replacing manual labor in repetitive, heavy, and potentially dangerous handling and flipping jobs.
[0065] like Figure 5 As shown, the rotary heating device 4 includes: a rotary drive assembly 410 connected to the partition plate 2 for rotating and switching the rotor position; a first mounting plate 420 connected to the upper surface of the partition plate 2 is provided on the side of the rotary drive assembly 410 away from the multi-degree-of-freedom automobile rotor picking and placing device 3; a first lifting assembly 430 is provided below the first mounting plate 420; and a heating assembly 440 connected to the partition plate 2 is provided above the first mounting plate 420. The heating assembly 440 is co-centered with the rotor. When the rotary drive assembly 410 rotates the rotor to be heated to the heating position, the first lifting assembly 430 acts on both sides of the rotor to lift the rotor to the preset heating position of the heating assembly 440 for automatic heating.
[0066] Specifically, the rotary drive assembly 410 can be a servo indexing plate or a rotary cylinder that drives multiple workstations, at least two: the feeding and heating workstations, to rotate and switch.
[0067] The first lifting assembly 430 is located below the first mounting plate 420. When the rotor rotates to the heating position, the lifting mechanism (such as a cylinder push rod) lifts the rotor from below, separating it from the support surface of the rotating disk, and precisely raises it to a fixed heating position, ensuring that the relative position of the rotor and the heating coil remains constant during each heating.
[0068] The heating element 440 is fixedly mounted above the partition plate 2 and is co-centered with the rotor. It is typically a medium-frequency induction heating coil.
[0069] It can improve cycle time, and the rotary indexing allows one station to feed materials while one rotor is heating, enabling the heating process to run in parallel with other processes; it can also ensure heating consistency, and the lifting positioning eliminates the slight height error that may exist in the rotary table itself, ensuring that the interval of each heating is consistent; it can also achieve precise temperature control, and the combination of fixed heating coils and precisely positioned rotors facilitates closed-loop temperature control.
[0070] like Figure 6 and Figure 8 As shown, the rotor bushing pre-loading device 6 includes: a pre-loading fixture 610 connected to the upper surface of the linear module 5, and a dummy shaft lifting assembly 620 connected to the lower surface of the partition plate 2 disposed below the pre-loading fixture 610. Specifically, the dummy shaft in the pre-filling fixture 610 is pulled out and lifted in a preset sequence by the dummy shaft lifting assembly 620 so that the shaft sleeve is pre-filled into the rotor.
[0071] Specifically, the pre-loading fixture 610 is installed on the slide table 510 of the linear module 5. It has a precision inner hole for placing the dummy shaft. The dummy shaft is a high-precision, high-surface-finish guide shaft, and its lower end is connected to the dummy shaft lifting assembly 620.
[0072] The dummy shaft lifting assembly 620 is fixed to the lower surface of the partition plate 2. It performs a compound action: first, the dummy shaft is pulled downwards a certain distance; then, after the bushing and rotor are placed on top of the dummy shaft, the dummy shaft is precisely lifted upwards, guiding the bushing into the rotor hole to a certain depth. This achieves a pre-filling effect. As a core pre-process for press-fit quality, the dummy shaft plays a guiding and centering role; the pulling action creates space for the robot arm to place the bushing on top of the dummy shaft; the lifting action, with the dummy shaft acting as a guide post 710, initially feeds the bushing into the rotor hole with excellent coaxiality and without jamming, eliminating the risk of the bushing colliding with the edge of the rotor hole. This solves the separation difficulties by separating the most careful and problematic steps—centering and initial introduction—from the high-pressure, high-speed final press-fit process, allowing it to be completed under low-pressure, controllable conditions, greatly improving the success rate and reliability of the final press-fit.
[0073] like Figure 7As shown, the pressing device 7 includes: a plurality of guide posts 710 vertically disposed on the upper surface of the partition plate 2; a pressure plate 720 horizontally disposed on the guide posts 710; a second mounting plate 730 horizontally disposed on the top of the guide posts 710; and an eighth drive assembly 740 disposed on the upper surface of the second mounting plate 730 and on both sides thereof. The output ends of the two eighth drive assemblies 740 are respectively connected to the pressure plate 720 horizontally disposed on the guide posts 710, for pressing down on the upper surface of the rotor to make it flat. The parallelism of the pressure plate 720 during the pressing process is ensured by the guide posts 710; multi-drive synchronous pressing is adopted to avoid uneven force on the rotor; and the upper surface of the rotor is leveled to ensure the stability of the pressing reference.
[0074] Specifically, the main frame consists of a guide post 710, a second mounting plate 730, a pressure plate 720 that can slide up and down along the guide post 710, and a moving plate 760, which can ensure good vertical movement.
[0075] The eighth drive assembly 740 is also the first-stage flattening mechanism. Two drive elements (such as a pneumatic-hydraulic booster cylinder) drive the pressure plate 720 to move downwards first and press it onto the upper surface of the rotor to ensure that the rotor is in an absolutely horizontal and stable state before final pressing, thus eliminating the risk of off-center load caused by uneven rotor placement surface.
[0076] Furthermore, a ninth drive assembly 750 is vertically mounted on the upper surface of the second mounting plate 730. A movable plate 760 is located at the output end of the ninth drive assembly 750. Two guide rods 770 are positioned opposite each other between the movable plate 760 and the second mounting plate 730. A pressure head 780 is located at the bottom of the movable plate 760. It can be understood that the ninth drive assembly 750 is also a second-stage main pressing mechanism. A servo electric cylinder or hydraulic cylinder located at the center of the second mounting plate 730 drives the movable plate 760 and the pressure head 780 at its bottom, providing the final, controllable pressing force. The guide rods 770 ensure stable movement of the movable plate 760. This enables high-precision axial pressing actions; simultaneously, the guide rod 770 structure prevents the pressure head 780 from being overloaded; and it can integrate pressure and displacement detection to achieve closed-loop control.
[0077] like Figure 9As shown, a limit retaining component 790 is provided between the second mounting plate 730 and the movable plate 760. The limit retaining component 790 includes a connecting block 7901 connected to the bottom of the second mounting plate 730. A tenth drive component 7902 is provided at the bottom of the connecting block 7901. A limit rod 7903 is horizontally provided at the output end of the tenth drive component 7902. The limit rod 7903 is inserted into the other end of a limit block 7904, one end of which is fixedly disposed on the upper surface of the movable plate 760, so that the movable plate 760 is limited and fixed when suspended. It can be understood that the tenth drive component 7902 serves as a safety limit retaining component 790, which can achieve the effect of mechanical safety. When the pressure head 780 is in a non-working state (suspended), the tenth drive component 7902 pushes the limit rod 7903 into the limit block 7904 on the movable plate 760, mechanically locking it to prevent the pressure head 780 from accidentally falling and causing damage to the equipment or product due to gas / power failure or other reasons.
[0078] Furthermore, it also includes: a conveyor line adjacent to the housing 1, located near the rotary heating device 4, with a rotor auxiliary feeding device 9 movably mounted on the conveyor line. The rotor auxiliary feeding device 9 is used for the multi-degree-of-freedom automotive rotor pick-and-place device 3 to grasp the rotor. It can be understood that the conveyor line is located at the automated logistics interface outside the equipment; the conveyor line (such as a roller conveyor or belt conveyor) transports the carrier (or pallet) carrying the rotor to the side of the equipment. After the rotor auxiliary feeding device 9 moves to the designated position, it lifts the rotor to be processed using the lifting part 8702, making it easy for subsequent devices to grasp, thereby ensuring that the rotor stops at a fixed position that the pick-and-place robot can accurately grasp each time. This enables automated docking with upstream and downstream processes, allowing the equipment to be embedded in automated production lines, reducing manual intervention, and forming the basis for building unmanned workshops.
[0079] Furthermore, the upper surface of the partition plate 2 is also provided with an eleventh drive assembly 10, parallel and adjacent to the linear module 5. The output end of the eleventh drive assembly 10 is connected to the slide table 510, and is used to drive the slide table 510 to reciprocate along the second direction, so as to synchronously drive the rotor bushing pre-filling device 6 to move in a specific direction. It can be understood that the eleventh drive assembly 10 is located on the upper surface of the partition plate 2, parallel to the linear module 5, and its output end is connected to the slide table 510, used to drive the slide table 510 to reciprocate along the second direction. This enables precise switching of the bushing pre-filling device, thereby improving the alignment accuracy of the rotor and the pressing mechanism, which in turn facilitates cycle control and process synchronization.
[0080] Furthermore, the counterweight transmission device 8 includes: Support component 810; Two first fixing seats 820 are disposed opposite each other on the top sides near the support assembly 810; Two sets of sprockets 830 are disposed opposite to each other on the upper surface of the first fixed seat 820; Two chains 840 are respectively engaged with a set of sprockets 830 on the same side; The first sliding component 850 is vertically disposed on one side of the support component 810 and is located between the two fixed seats; The second sliding component 860 is disposed on the support component 810 opposite to the first sliding component 850; The second lifting component 870 is connected to the first sliding component 850, and its two ends are respectively connected to one end of the two chains 840; The counterweight assembly 880 is connected to the second sliding assembly 860, and its two ends are respectively connected to the other ends of the two chains 840; The transmission assembly 890 is vertically disposed within the support assembly 810 and connected to the counterweight assembly 880; and The twelfth drive assembly 8100 is connected to the support assembly 810, and its output end is connected to the bottom of the transmission assembly 890; The drive assembly has a drive state and a release state. In the drive state, the drive assembly drives the transmission assembly 890 to move radially upward, simultaneously driving the counterweight assembly 880 and one end of the chain 840 to move upward, so that the second lifting assembly 870 at the other end of the chain 840 moves downward. In the release state, the counterweight assembly 880, under its own gravity, drives one end of the chain 840 to move downward, so that the second lifting assembly 870 at the other end of the chain 840 moves upward.
[0081] Specifically, such as Figures 14-17 As shown, this application relates to a counterweight force transmission device 8. (As indicated...) Figure 14 and Figure 16 As shown, the counterweight transmission device 8 includes a support assembly 810. The support assembly 810 serves as the basic load-bearing structure for the entire counterweight transmission device 8, used to install and fix the first fixed base 820, the first sliding assembly 850, the second sliding assembly 860, the transmission assembly 890, and the drive assembly. It typically adopts a welded steel frame, an aluminum profile frame, or a box-type structure. It provides a stable and reliable installation reference for vertically moving components; simultaneously, it ensures that the structure does not deform during chain 840 transmission; and it facilitates modular integration of the device into existing equipment.
[0082] Two first fixed seats 820 are disposed opposite each other on the top sides near the support assembly 810; they are used to support the sprocket 830 assembly and form a symmetrical transmission structure. This ensures that the two sprockets 830 are symmetrically positioned, avoids uneven force on the chain 840, thereby improving the stability of the chain 840 operation, preventing uneven wear or chain skipping, and thus providing a stable force path for the counterweight assembly 880 and the second lifting assembly 870.
[0083] Two sets of sprockets 830 are disposed opposite to each other on the upper surface of the first fixed seat 820; the sprockets 830 are respectively installed on the upper surface of the two first fixed seats 820 to change the direction of movement of the chain 840, so that the chain 840 can transmit force in the vertical direction.
[0084] Two chains 840 are respectively engaged with a set of sprockets 830 on the same side; the two chains 840 are respectively engaged with two sets of sprockets 830 on the left and right sides, forming a symmetrical closed-loop transmission path. One end of the chain is connected to the second lifting assembly 870, and the other end is connected to the counterweight assembly 880. This enables synchronous transmission of force, avoids unilateral force, and thus improves the overall operational stability.
[0085] The first sliding component 850 is vertically disposed on one side of the support component 810 and located between the two fixed seats; it can guide the second lifting component 870 so that it can move smoothly in the vertical direction.
[0086] The second sliding component 860 is disposed on the support component 810 opposite to the first sliding component 850; it can vertically guide the counterweight component 880 to ensure that the counterweight component 880 only moves up and down.
[0087] The second lifting component 870 is connected to the first sliding component 850, and its two ends are respectively connected to one end of the two chains 840; thus, it can achieve a good lifting effect.
[0088] The counterweight assembly 880 is connected to the second sliding assembly 860, and its two ends are respectively connected to the other ends of the two chains 840; The transmission component 890 is vertically disposed within the support component 810 and connected to the counterweight component 880; it is capable of transmitting driving force to the counterweight component 880.
[0089] The drive component is connected to the support component 810, and its output end is connected to the bottom of the transmission component 890; it can achieve the effect of switching between the drive state and the release state.
[0090] The drive assembly has a drive state and a release state. In the drive state, the drive assembly drives the transmission assembly 890 to move radially upward, simultaneously driving the counterweight assembly 880 and one end of the chain 840 to move upward, so that the second lifting assembly 870 at the other end of the chain 840 moves downward. In the release state, the counterweight assembly 880, under its own gravity, drives one end of the chain 840 to move downward, so that the second lifting assembly 870 at the other end of the chain 840 moves upward.
[0091] Specifically, the working principle of this invention is as follows: Driven state (load reduction): When it is necessary to reduce the weight of the second lifting component 870 and its load, the drive component 81002 is activated (drive state), driving the ball screw 8902 to rotate forward, causing the movable seat 8904 to move upward; the movable seat 8904 drives the counterweight component 880 to move upward along the second slide rail 8601, and at the same time pulls one end of the chain 840 upward through the movable seat 8801; since the chain 840 passes around the sprocket 830, the second lifting component 870 at the other end moves downward along the first slide rail 8501 under the traction of gravity and the chain 840, realizing the reduction of the load; during this process, the energy provided by the drive component 81002 is mainly used to lift the heavier counterweight component 880 and overcome system friction, and the gravitational potential energy of the load is converted into the potential energy of the counterweight for storage.
[0092] Release state (load rising): When it is necessary to raise the second lifting component 870, the drive component 81002 can stop providing power or apply a small reverse braking force (release state); since the weight of the counterweight component 880 is greater than the total weight of the second lifting component 870 and the load, the counterweight component 880 tends to descend under its own gravity; at this time, the drive component 81002 can control the release speed (such as through motor braking or reverse micro-motion); the counterweight component 880 moves down, pulling the rear end of the chain 840 down, thereby pulling the front end of the chain 840 to drive the second lifting component 870 to move upward along the first slide rail 8501, realizing the lifting of the load; this process is mainly driven by the gravitational potential energy of the counterweight, with extremely low energy consumption.
[0093] As can be seen from the above description, this application achieves the following technical effects: In this embodiment, gravity transmission is employed. The drive component has a drive state and a release state. In the drive state, the drive component drives the transmission component 890 to move radially upward, simultaneously moving the counterweight component 880 and one end of the chain 840 upward, so that the second lifting component 870 at the other end of the chain 840 moves downward. In the release state, the counterweight component 880, under its own gravity, moves one end of the chain 840 downward, so that the second lifting component 870 at the other end of the chain 840 moves upward. This achieves the purpose of driving the second lifting component 870 to move vertically and directionally, thereby realizing the technical effect of recovering gravity and saving energy. This solves the technical problem of traditional drive methods, such as direct drive by cylinders, hydraulic cylinders, or electric push rods, which require a lot of energy to overcome the load's gravity when lifting the load, and when descending, the gravitational potential energy of the load is usually consumed through braking or damping, resulting in energy waste. This energy consumption problem is particularly prominent in applications that require frequent lifting or heavy loads.
[0094] Furthermore, the support component 810 includes: a top plate 8101, first side plates 8102 symmetrically arranged on both sides of the bottom of the top plate 8101, and a second side plate 8103 arranged between the two first side plates 8102. The top plate 8101, the two first side plates 8102, and the second side plate 8103 together form a semi-open support frame. It is understood that this semi-open support frame, while ensuring the overall structural strength, keeps one side of the frame open, facilitating the installation, maintenance, and observation of the internal transmission assembly 890, sliding assembly 3140, and counterweight assembly 880.
[0095] like Figure 17 As shown, several through slots 81021 for weight reduction are symmetrically provided on the two first side plates 8102. It can be understood that this can reduce the weight of the support component 810 and reduce drive energy consumption; at the same time, the symmetrical arrangement avoids structural stress imbalance.
[0096] Preferably, the through groove 81021 can be elongated, honeycomb-shaped, or rounded rectangular.
[0097] Furthermore, the first sliding assembly 850 includes two first slide rails 8501 vertically disposed on the outer side of the second side plate 8103, and two first sliders 8502 respectively disposed on the two first slide rails 8501. It can be understood that this can provide high-precision vertical guidance for the second lifting assembly 870; at the same time, the double slide rail structure improves torsional resistance and prevents lifting deviation.
[0098] Furthermore, the second sliding assembly 860 includes: two second slide rails 8601 vertically disposed on the first side plate 8102 away from the second side plate 8103, and two second sliders 8602 respectively disposed on the two second slide rails 8601; The two first slide rails 8501 are located between the two second slide rails 8601. It can be understood that by operating the second lifting component 870 and the counterweight component 880 in different guide areas, the lifting motion and the counterweight motion can be effectively isolated to avoid interference; at the same time, the overall layout compactness can be improved.
[0099] like Figure 15 As shown, the drive assembly includes a second fixed base 81001 connected to a side wall near the bottom of the second side plate 8103. A drive component 81002 is mounted on the second fixed base 81001, with its output end facing the top plate 8101. It can be understood that the drive assembly outputs power from bottom to top, ensuring that the direction of the driving force is consistent with the direction of movement of the counterweight and transmission assembly 890; this reduces force loss in the transmission path.
[0100] Of course, the drive component 81002 can be a three-phase motor.
[0101] Furthermore, the transmission assembly 890 includes: two screw support seats 8901 vertically opposite each other on the inner wall of the second side plate 8103, a ball screw 8902 disposed between the two screw support seats 8901, one end of the ball screw 8902 being connected to the output end of the drive component 81002 via a connector 8903, and a movable seat 8904 disposed on the screw. It can be understood that the ball screw 8902 converts the rotational motion of the drive component into the linear lifting motion of the movable seat 8904; it can achieve high transmission efficiency and high positioning accuracy; and it can also achieve strong load-bearing capacity, making it suitable for counterweight systems. Furthermore, two third sliding components 3140 are vertically arranged between the movable seat 8904 and the second side plate 8103. It can be understood that the third sliding components 3140 provide auxiliary guidance for the movable seat 8904, preventing the ball screw 8902 from bearing lateral force alone. This extends the service life of the ball screw 8902 and improves overall operational stability. The third sliding component 3140 also includes a slide rail and a slider.
[0102] Furthermore, the counterweight assembly 880 includes a movable seat 8801 connected to the two second sliders 8602 and the movable seat 8904. The movable seat 8801 is provided with a plurality of counterweight blocks 8802, and a detachable limiting part 8803 is also provided on the movable seat 8801. It can be understood that the movable seat 8801, as the main body supporting the counterweight, constrains the counterweight blocks 8802 through the limiting part 8803 to prevent them from falling off during operation.
[0103] like Figure 16 As shown, the second lifting assembly 870 includes a fourth connecting plate 8701 connected to the two first sliders 8502, and a lifting part 8702 is provided on the top of the fourth connecting plate 8701. It is understood that this enables a good lifting effect.
[0104] Furthermore, the weight of the second lifting component 870 is less than the weight of the counterweight component 880. It is understood that, through this weight difference design, the counterweight component 880 can automatically drive the second lifting component 870 upwards using its own weight when the device is in the released state.
[0105] It is important to know that in order to improve the operating accuracy of the device or component, multiple limit sensors are installed for precise positioning.
[0106] Furthermore, an electrical control box is also provided inside the housing 1, which is electrically connected to multiple drive components and sensors. This enables precise electrical control. Those skilled in the art will be familiar with electrical control boxes, and they are not limited to this application.
