[0028] See Figures 1 to 4As shown in the embodiment of this application, a lifting device is provided, including a lifting device 10 and a guiding mechanism 20. The lifting device 10 includes a base plate 11 and a lifting assembly 12, a positioning assembly 13, a clamping assembly 14, and a sliding assembly 15, all fixedly connected to the base plate 11. The lifting assembly 12 is connected to an external driving device to control the movement of the lifting device 10. The lifting device 10 has a workpiece gripping state where the positioning assembly 13 positions the workpiece so that the clamping assembly 14 clamps the workpiece. The guiding mechanism 20 includes two parallel guide rails 21, one end of which is fixed to a workpiece assembly platform. The lifting device 10 also has a workpiece assembly state where the sliding assembly 15 abuts against the guide rails and can move relative to the length direction of the guide rails 21.

[0029] It is understood that the workpiece in this embodiment includes an electric drive controller. In automated production lines, the assembly and loading of electric drive controllers requires high positional accuracy. If there is a large error in the assembly, it can easily lead to bumps and damage to the electric drive controller, affecting the quality of the final product.

[0030] Specifically, when the lifting device 10 is in the workpiece gripping state, it means that after the lifting device 10 moves to the workpiece position, it is controlled by an external drive device connected to the lifting assembly 12 to descend vertically. The positioning assembly 13 accurately positions the workpiece, and then the clamping assembly 14 clamps the workpiece before the lifting device is controlled by the external drive device to rise vertically. When the lifting device 10 is in the workpiece assembly state, it means that after the lifting device 10 moves the workpiece to the workpiece assembly platform, the sliding assemblies 15 at both ends of the lifting device abut against the two guide rails 21 fixed to the guide mechanism 20 on the workpiece assembly platform. After the sliding assemblies 15 abut against the guide rails 21, they can be controlled by the external drive device to roll up and down on the guide rails 21 to assemble the workpiece. The external drive device includes electric drive devices and manual drive devices.

[0031] In this embodiment, by respectively assembling a lifting assembly 12 for fixed connection with an external drive device, a positioning assembly 13 for positioning the workpiece, a clamping assembly 14 for clamping the workpiece after positioning, and a sliding assembly 15 for cooperating with a guide mechanism to install the workpiece on the base plate 11 of the lifting device 10, the workpiece can be moved from one position to another for assembly. The coordinated use of the lifting assembly 12, positioning assembly 13, and clamping assembly 14 allows the workpiece to be quickly moved to the workpiece assembly platform before assembly, improving the workpiece assembly efficiency. Furthermore, the cooperation between the sliding assembly 15 and the guide rail 21 of the guide mechanism 20 allows the workpiece to be more accurately docked with the equipment to be assembled, improving the accuracy of workpiece assembly, reducing assembly errors, and avoiding workpiece damage. This is especially important for electric drive controllers, which are generally used in electric vehicles and other fields, and are mainly assembled in automated production lines where high assembly precision is required. The lifting device in this embodiment can improve the assembly precision of the electric drive controller, reduce damage during assembly, and improve the overall quality of the final product.

[0032] Furthermore, the positioning component 13 includes a workpiece guide block 131 and a positioning pin 132. The workpiece guide block 131 is disposed at the bottom of the substrate 11 and extends in a direction perpendicular to the substrate 11. An inclined portion 1311 is provided on the inner side of the end of the workpiece guide block 131 away from the substrate 11. The positioning pin 132 is disposed at the bottom of the substrate 11 and extends in a direction perpendicular to the substrate 11.

[0033] Furthermore, when the lifting device 10 is in the workpiece gripping state, the inclined portion 1311 abuts against the workpiece, and the positioning pin 132 is inserted into the positioning hole of the workpiece. During the process of the external drive device driving the lifting device to move vertically downward toward the workpiece, the workpiece guide block 131 on the lifting device 10 will first contact the workpiece. In this embodiment, there are 4 workpiece guide blocks 131. During the process of the lifting device 10 continuing to move downward, the inclined portions 1311 on the inner side of the 4 workpiece guide blocks 131 contact the workpiece respectively, so as to align the positioning hole of the workpiece with the positioning pin 132 on the lifting device 10, and finally realize the insertion of the positioning pin 132 into the positioning hole of the workpiece.

[0034] In this embodiment, the inclined portion 1311 at the bottom of the workpiece guide block 131 contacts the workpiece first when the lifting device 10 approaches the workpiece. When the inclined portions 1311 of the four workpiece guide blocks 131 contact the workpiece, a force is generated, causing a slight adjustment displacement of the workpiece in the horizontal direction. Simultaneously, the positioning pin 132 extends in a direction perpendicular to the base plate 11. After the workpiece is positioned by the workpiece guide blocks 131, the positioning hole on the workpiece can be accurately aligned with the positioning pin 132 on the lifting device. This is based on the guiding principle of the inclined surface and the geometric positioning principle; through the guiding effect of the inclined portion and the precise cooperation between the positioning pin and the positioning hole, accurate positioning of the workpiece is achieved. Four workpiece guide blocks 131 are distributed along the bottom of the base plate 11. When the lifting device 10 descends vertically, the inclined portions 1311 on the workpiece guide blocks 131 contact the workpiece. As the lifting device 10 continues to descend, the friction and pressing forces between the inclined portions 1311 and the workpiece work together to gradually bring the workpiece's positioning hole closer to the positioning pin 132. This converts the vertical downward movement of the lifting device 10 into an effective guiding force for the workpiece in the horizontal direction. This efficient guiding function significantly shortens the positioning time and improves work efficiency. In automated production workshops for electric drive controllers, rapid positioning makes the entire lifting and assembly process smoother, reduces equipment waiting time, increases the overall operating speed of the production line, and increases output per unit time. After the positioning pin 132 is inserted into the positioning hole of the workpiece, combined with the subsequent clamping assembly 14, the workpiece and the lifting device 10 form a stable whole, restricting multiple degrees of freedom of the workpiece in the horizontal and vertical directions, ensuring that the workpiece will not sway or shift during lifting. This ensures the safety of the hoisting process, avoids accidents such as collisions and falls caused by workpiece shaking, protects the safety of personnel and equipment, and also protects the workpiece itself from damage.

[0035] Furthermore, the clamping assembly 14 includes a manual elbow clamp 141, a first clamping part 142, and a second clamping part 143. A linkage component 144 is provided between the first clamping part 142 and the second clamping part 143, respectively movably connected to both. The manual elbow clamp 141 is movably connected to either the first clamping part 142 or the second clamping part 143 to drive them to clamp the workpiece. The manual elbow clamp 141, as a driving component for controlling the clamping assembly 14 to clamp the workpiece, can be located in either the first clamping part 142 or the second clamping part 143. Figure 2As shown, the manual elbow clamp 141 is provided with a drive handle 1411. By turning the drive handle 1411 inward (i.e., the side of the manual elbow clamp 141 closer to the first clamping part 142 or the second clamping part 143), the linkage component 144 connecting the first clamping part 142 and the second clamping part 143 will rotate under the action of the first clamping part 142 or the second clamping part 143, thereby causing the first clamping part 142 and the second clamping part 143 to move towards each other, so as to clamp the workpiece through the first clamping part 142 and the second clamping part 143.

[0036] The manual elbow clamp 141 rotates when the drive handle 1411 is turned. The first clamping part 142 and the second clamping part 143, which are movably connected to the manual elbow clamp 141, move accordingly, driving the linkage component 144 to rotate. This causes the first clamping part 142 and the second clamping part 143 to move towards each other and clamp the workpiece. This embodiment utilizes the lever principle and the mechanical linkage principle. The manual operation of the manual elbow clamp 141 is simple and direct, requiring no complex power source or control system, reducing equipment costs and maintenance difficulty. Furthermore, operators can respond quickly and flexibly control the clamping action according to the actual situation, enhancing the applicability of the lifting device for work scenarios requiring frequent adjustments to clamping force or clamping workpieces of different shapes. The mechanical linkage ensures the uniformity and stability of the clamping force, reliably clamping the workpiece and preventing it from falling off during lifting.

[0037] Furthermore, the linkage component 144 includes an elongated support portion 1441, a first transmission rod 1442, and a second transmission rod 1443. The elongated support portion 1441 is rotatably disposed on the top of the substrate 11, and the first transmission rod 1442 and the second transmission rod 1443 are respectively movably connected to the two ends of the elongated support portion 1441.

[0038] Specifically, in this embodiment, the linkage component 144 achieves force transmission and motion conversion based on the linkage transmission principle. The elongated support portion 1441 is rotatably mounted on the top of the base plate 11, serving as a transmission hub. When the first clamping portion 142 or the second clamping portion 143 moves due to the action of the manual elbow clamp 141, it drives the connected first transmission rod 1442 or second transmission rod 1443 to move, causing the elongated support portion 1441 to rotate accordingly. This, in turn, drives the transmission rod at the other end, causing the two clamping portions to move towards or away from each other. The reliable linkage mechanism ensures the synchronization and coordination of the clamping action, allowing the two clamping portions to apply clamping force evenly to the workpiece, avoiding workpiece deformation or unstable clamping due to uneven force. The rotatable design of the elongated support portion 1441 increases the flexibility of the transmission, adapting to the clamping requirements of workpieces of different sizes and shapes, and improving the versatility and practicality of the lifting device.

[0039] Furthermore, the first clamping part 142 and the second clamping part 143 are respectively provided with clamping blocks 145 that pass through the substrate 11 and extend in a direction away from the top of the substrate 11. The end of the clamping block 145 away from the substrate 11 is provided with a protrusion 146 that extends in a direction away from the guide rail 21.

[0040] In this embodiment, clamping blocks 145 are respectively provided on the first clamping part 142 and the second clamping part 143, which pass through the substrate 11 and extend away from the top of the substrate 11, and the clamping blocks 145 are provided with protrusions 146. When the first clamping part 142 and the second clamping part 143 clamp the workpiece, the protrusions 146 on the clamping blocks 145 abut against the workpiece from the side. By utilizing the principle of physical blocking, the resistance to the workpiece falling off is increased, which effectively prevents the workpiece from falling off the clamping assembly due to vibration, shaking or other unexpected situations during the hoisting process, thereby improving the safety and stability of the hoisting.

[0041] Furthermore, the sliding assembly 15 includes a bearing base plate 151 and a bearing component 152. The bearing base plate 151 is fixedly connected to the base plate 11, and the bearing component 152 is rotatably disposed on the bearing base plate 151. When the lifting device 10 is in the workpiece assembly state, the bearing component 152 abuts against the guide rail 21 and can roll along the length direction of the guide rail 21. When the lifting device 10 descends to the point where the sliding assembly 15 contacts the guide rail 21 of the guide mechanism 20, if the vertical movement of the lifting device 10 is continued, the sliding assembly 15 can roll on the guide rail 21 to prevent the workpiece from being difficult to align with the predetermined equipment on the workpiece assembly platform due to the shaking of the lifting device 10, thus preventing the workpiece from being difficult to assemble with the predetermined equipment.

[0042] Furthermore, a positioning plate 211 is provided at one end of the guide rail 21 near the base plate 11. A guide groove 212 is provided through the surface of the positioning plate 211 along the length direction of the guide rail 21. When the lifting device 10 is in the workpiece assembly state, the bearing component 152 abuts against the guide groove 212 and can roll along the length direction of the guide groove 212. When the sliding component 15 contacts the guide rail 21, the guide groove 212 on the positioning plate 211 can limit the bearing component 152 on the lifting device 10, so that the bearing component 152 can roll along the length direction of the guide rail 21 within the guide groove 212. The guide groove 212 restricts the movement trajectory of the bearing component 152, so that it can only move along the length direction of the guide rail. This precise guiding and limiting function ensures the movement accuracy of the lifting device 10 during the workpiece assembly process, reduces assembly errors, and improves assembly quality. At the same time, the limiting effect of the guide groove 212 on the bearing component 152 enhances the stability of the lifting device 10 during movement, prevents it from lateral displacement or shaking, and ensures the safe assembly of the workpiece.

[0043] Further, the bearing component 152 includes a pre-guide bearing 1521, a guide bearing 1522, and a guide bearing 1523. The pre-guide bearing 1521 is disposed at the end of the bearing substrate 151 away from the substrate 11, the guide bearing 1523 is disposed at the end of the bearing substrate close to the substrate 11, and the guide bearing 1522 is disposed on the substrate 11 and located between the pre-guide bearing 1521 and the guide bearing 1523. The guide groove 212 includes a first guide groove 2121 and a second guide groove 2122. When the lifting device 10 is in the workpiece assembly state, the pre-guide bearing 1521 abuts against the first guide groove 2121 and can roll along the length direction of the first guide groove 2121, the guide bearing 1522 abuts against the second guide groove 2122 and can move along the length direction of the second guide groove 2122, and the guide bearing 1523 abuts against the first guide groove 2121 and can move along the length direction of the first guide groove 2121.

[0044] refer to Figure 2 As shown, in this embodiment, two pre-guide bearings 1521 are provided and symmetrically arranged on both sides of the end of the bearing substrate 151 away from the substrate 11. Two guide bearings 1523 are provided and symmetrically arranged on both sides of the end of the bearing substrate 151 close to the substrate 11. Two guide bearings 1522 are provided and arranged in a direction perpendicular to the substrate 11. The two guide bearings 1522 are arranged between the pre-guide bearings 1521 and the guide bearings 1523. Therefore, when assembling the workpiece on the workpiece assembly platform, the pre-guide bearing 1521 first abuts against the first guide groove 2121 and rolls vertically downward along the first guide groove 2121, controlling the lifting device 10 within the two guide rails 21. As the lifting device 10 continues to descend, the guide bearing 1522 abuts against the second guide groove 2122 and rolls vertically along the second guide groove 2122. The second guide groove 2122 can limit the direction of the guide bearing 1522 in directions other than the vertical direction, thereby guiding the lifting device 10. After the lifting device 10 continues to descend to a predetermined distance, the guide bearing 1523 abuts against the first guide groove 2121 and rolls along the first guide groove 2121, so that the workpiece moves to a position where it can be assembled with the predetermined equipment. In this embodiment, the length of the first guide groove 2121 and the length of the second guide groove 2122 are both greater than the vertical distance at which the workpiece clamped on the lifting device 10 descends to a position where it can be assembled with the predetermined equipment.

[0045] In this embodiment, the bearing component 152 consists of a pre-guide bearing 1521, a guide bearing 1522, and a guide bearing 1523. The guide groove 212 includes a first guide groove 2121 and a second guide groove 2122. When the lifting device 10 is in the workpiece assembly state and the clamping assembly 14 of the lifting device 10 clamps the workpiece and descends vertically near the predetermined equipment, the pre-guide bearing 1521 first abuts against the first guide groove 2121, using symmetrical distribution to achieve preliminary guidance and control the lifting device 10 between the two guide rails 21. Then, when the lifting device 10 continues to descend to a specific position, the guide bearing 1522 cooperates with the second guide groove 2122 to achieve all-round limiting and guiding. When the lifting device 10 continues to descend to the predetermined position, the guide bearing 1523 cooperates with the first guide groove 2121 to assist in moving the workpiece to the assembly position. Multi-stage orderly guidance ensures the accurate movement and positioning of the lifting device 10 during the assembly process. Through the gradual advancement of pre-guidance, guiding, and final guidance, it can adapt to the complex requirements of different assembly scenarios and improve the assembly success rate. In the assembly of large equipment such as electric drive controllers, accurate alignment during assembly can be ensured, reducing assembly difficulties and rework caused by positioning deviations, lowering assembly costs, and improving production efficiency. Simultaneously, the orderly guidance at each stage enhances the stability of the lifting device 10 throughout the assembly process, reducing unexpected shaking and deviations, and ensuring the safety of the assembly operation. The lengths of both the first guide groove 2121 and the second guide groove 2122 are greater than the vertical distance from the workpiece's descent to the assembly position, providing sufficient guiding space for assemblies with different heights and stroke requirements. This accommodates workpieces of various sizes and assembly processes, preventing inaccurate workpiece assembly after the bearing component 152 disengages from the guide groove 212 due to insufficient length of the first guide groove 2121 and the second guide groove 2122.

[0046] Furthermore, the lifting assembly 12 includes a plurality of lifting rings 121 disposed along the outer edge of the substrate 11. The plurality of lifting rings 121 are located on the top of the substrate 11 and are connected to an external drive device to control the movement of the lifting device 10.

[0047] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0048] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
