Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for assembling dual-motor drive assemblies for new energy vehicles, specifically to a multi-purpose manual tilting device for assembling dual-motor drive powertrains for new energy vehicles. Background Technology

[0002] Currently, electric vehicles mainly use a single-motor, single-ratio reducer transmission. However, with the continuous improvement of vehicle performance, some vehicles are now using dual-motor drive systems. Dual-motor power coupling systems use two smaller motors coupled together. This reduces the manufacturing difficulties of large motors and allows for increased motor load capacity through separate or coupled driving by the two smaller motors. Furthermore, by using speed-torque coupling, the operating range of the motors can be adjusted, ensuring they operate within a high-efficiency range and improving the driving range of the electric vehicle.

[0003] During the assembly of a dual-motor drive assembly, it needs to be flipped so that the part to be assembled faces upwards, facilitating assembly by robotic arms or manual labor. Therefore, a flipping device is usually used. Currently available flipping equipment is highly specialized, with a single device flipping only the assembly or a single component such as the housing. In some projects, cost-effectiveness is required while meeting assembly requirements, so such equipment is mostly used in the early product prototyping stage. However, such single-function equipment cannot meet the needs and ultimately increases the project cost.

[0004] The aforementioned equipment is designed for single functions, which may lead to an increase in the number of devices required to meet the needs of each stage of the project during planning, resulting in increased project costs. Summary of the Invention

The floating clamp assembly 1 and the floating clamp assembly 2 can be used selectively or simultaneously to adapt to the flipping of the dual-motor drive assembly or the flipping of a single motor assembly.

[0008] Furthermore, the dual-motor drive assembly tilting device also includes a docking trolley; the docking trolley includes a trolley frame, a fixed base plate, and a horizontal floating plate; the horizontal floating plate is provided with positioning pins and support columns that match the dual-motor drive assembly or a single motor assembly.

[0009] Furthermore, the linear motion mechanism includes a pair of linear guide rails disposed on the support base and a plurality of sliders disposed at the rear end of the fixed plate.

[0010] Furthermore, the upper and lower ends of the left rotating plate and the right rotating plate are respectively provided with guide positioning posts, and the horizontal floating plate is provided with positioning holes that cooperate with the guide positioning posts.

[0011] Furthermore, the bottom of the support base is provided with a support base plate, the support base plate has a U-shaped groove, and guide components are provided on both sides of the U-shaped groove.

[0016] Furthermore, both the first floating clamp assembly and the second floating clamp assembly are connected to a push-pull elbow clamp, and the base of the push-pull elbow clamp is fixed to the left rotating plate or the right rotating plate.

[0032] 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.

[0033] like Figures 1-6 As shown, the dual-motor drive assembly flipping device of the present invention includes a flipping device support frame assembly 10, a flipping clamp assembly 20, and a rotating docking trolley 30. The main function of the flipping clamp assembly 20 is to clamp the product tightly to achieve a 360° flip. The rotating docking trolley 30 is equipped with a multi-functional positioning fixture to realize the product rotation and positioning functions.

[0034] like Figure 2 As shown, the support frame assembly 10 includes a support base 11, a support base plate 12, and a linear motion mechanism extending in the vertical direction; the support base 11 is used to support the moving flip-clamp assembly 20; the support base plate 12 of the equipment frame is fixed to the support base 11; the flip-clamp assembly 20 is slidably connected to the support frame assembly 10 through the linear motion mechanism.

[0035] like Figure 2 , Figure 3As shown, the flip-grip assembly 20 has a fixed plate 201, on which several sliders 210 are distributed left and right. Specifically, four sliders 210 are used, but six or eight can also be used. A linear guide rail 14 is provided on the support base 11. The sliders 210 are connected to the linear guide rail 14 to form a linear motion mechanism. A lifting ring is provided at the top of the fixed plate, allowing the flip-grip assembly 20 to slide up and down on the support frame assembly 10 along the linear motion mechanism using a crane or manual hoist. In addition, upper limit components 15 and lower limit components 16 are provided at both ends of the linear guide rail 14 to limit movement.

[0036] like Figure 3 As shown, a right cantilever support column 202 and a left cantilever support column 203 are fixed on the other side of the fixed plate 201. The left cantilever support column 203 is connected to a left rotating plate 207 through a rotating mechanism one, and the right cantilever support column 202 is also connected to a right rotating plate 206 through a rotating mechanism two. The right cantilever support column 202 is also provided with a rotating drive mechanism connected to the rotating mechanism two. At the same time, the left rotating plate 207 and the right rotating plate 206 are bridged by a connecting rod 221.

[0037] The left rotating plate 207 and the right rotating plate 206 are respectively provided with a floating clamp assembly 215 for positioning the left motor assembly at one end, and a floating clamp assembly 217 for positioning the right motor assembly at the other end. The two floating clamp assemblies 215 are symmetrically arranged, and the two floating clamp assemblies 217 are also symmetrically arranged. The floating clamp assemblies 215 and 217 are provided with a number of positioning pins and support columns, which can be adjusted and replaced according to the shape of the product.

[0038] During the assembly of the dual-motor drive assembly, the floating clamp assembly 215 and the floating clamp assembly 217 can be used selectively or simultaneously to accommodate the flipping of the dual-motor drive assembly or the flipping of a single motor assembly.

[0039] Specifically, such as Figure 3 As shown, one end of the right cantilever support column 202 is fixed to the fixed plate 201, and the other end of the right cantilever support column 202 is fixed with a bearing seat 205 and a reducer 209; a rotating handwheel 211 is provided on the reducer 209; the active rotating shaft 220 is fixed on the bearing seat 205, one end of the active rotating shaft 220 is connected to the output hole of the reducer 209, and the other end is connected to the right rotating plate 206. The rotation output of the reducer 209 causes the rotation of the active rotating shaft 220 to drive the right rotating plate 206 to rotate.

[0040] One end of the left cantilever support column 203 is fixed to the fixed plate 201, and the other end of the left cantilever support column 203 is connected to the bearing seat 204. The bearing seat 204 is equipped with a driven rotating shaft 219, which is connected to the left rotating plate 207. A connecting rod 221 is connected between the left rotating plate 207 and the right rotating plate 206. The connecting rod is mainly used to bridge the left and right rotating plates, so that the active rotating shaft drives the driven rotating shaft to rotate.

[0041] The right rotating plate 206 and the left rotating plate 207 are equipped with floating clamp assembly 1 215 and floating clamp assembly 217, respectively. These floating assemblies are connected to floating rods 214. The outer side of the floating rods 214 is also provided with guide sleeves and linear bearing seats 222. All floating rods 214 are respectively inserted into the linear bearing seats 222. The linear bearing seats 222 and guide sleeves 208 are respectively fixed on the left rotating plate and the right rotating plate.

[0042] In addition, each floating clamp assembly is connected to a push-pull elbow clamp 212, the base of which is fixed to the rotating plate. This allows the floating clamp to hold the outer contour shell of the product.

[0043] like Figure 4 As shown, the main components of the docking trolley 30 include a trolley frame 310, a fixed base plate 307, and a horizontal floating plate 301. The fixed base plate 307 is connected and fixed to the trolley frame 310. Various positioning pins, support columns, and positioning holes 302 are fixed on the horizontal floating plate 301. Springs 306 are distributed at the bottom of the horizontal floating plate to play a floating role.

[0044] The left rotating plate 207 and the right rotating plate 206 are respectively provided with guide positioning posts 213 at their upper and lower ends. The positioning holes 302 cooperate with the guide positioning posts 213 at both ends of the left and right rotating plates, mainly for guiding and positioning the trolley. When the flip clamping assembly 20 needs to take the product off the trolley, it will use the positioning holes 302 to limit the position accuracy.

[0045] The docking trolley 30 has fixed limit plates 308 on both sides; the supporting base plate 12 has a U-shaped groove, and guide components 13 are respectively provided on both sides of the U-shaped groove. The limit plates 308 and the guide components 13 are slidably engaged. The guide components 13 mainly guide and limit the trolley when it is pushed in.

[0046] The front end of the trolley 30 is provided with a quick-change limiting top rod 309, and the support base plate 12 is also provided with a trolley limiting component 17. The quick-change limiting top rod 309 and the trolley limiting component 17 cooperate to limit the position of the trolley when it is pushed into the equipment. When the trolley is pushed into the equipment, it will hit the trolley limiting component 17, making the trolley unable to move and thus playing a limiting role.

[0047] One end of the fixed base plate 307 is also provided with a quick-change parts storage area 312, which is the location for storing positioning pins and support columns for changing different quick-change parts. The positioning pins and support columns are matched with the dual-motor drive assembly or the single motor assembly. By quickly changing the positioning pins and support columns, the dual-motor drive assembly can be used for transportation and the left and right motor assemblies can be operated independently.

[0048] The trolley frame 310 is equipped with casters 313, handles 311, and guide blocks 314. The guide blocks 314 are located at the bottom front end of the trolley frame 310 and serve as guides when the trolley is pushed into the equipment. The casters 313 and handles 311 make it very convenient to use the rotating docking trolley to transport the dual-motor drive assembly or the left and right motor assemblies.

[0049] It should be noted that, in another embodiment, in order to realize the up and down movement of the flipping clamp assembly, the linear motion mechanism can be controlled by a servo motor and a lead screw; it can also be controlled by a cylinder or manually controlled by a worm gear and a counterweight; in addition, the push-pull elbow clamp of the present invention can be replaced by automatic cylinder control; the manually rotated worm gear reducer can be controlled by a geared motor.

[0050] The working principle and process of the dual-motor drive assembly flipping device of the present invention are briefly described below with reference to the accompanying drawings.

[0051] First, place the motor housing 40 onto the docking trolley 30 and position it in the corresponding location (e.g., Figure 5 The trolley 30 is pushed into the tilting device from the front. The position is automatically adjusted by the guide components on both sides. Then it is pushed all the way in so that the quick-change limit rod 309 on the transport vehicle hits the trolley limit component 17. In this way, the transport vehicle is pushed into place. At the same time, the tilting clamp component is in a high position.

[0052] When the product is pushed into the tilting clamp, the position of the tilting clamp assembly can be adjusted by manually cranking the rotating handwheel 211. It should be noted that the floating clamp on the tilting clamp assembly requires a corresponding product; the product and clamp must be properly matched. Once the position is adjusted, the tilting clamp assembly 20 needs to be lowered. The guide positioning post 213 on the tilting clamp assembly will be guided into the positioning hole 302 on the floating plate of the transport vehicle, ensuring that the clamp assembly, the floating plate on the transport vehicle, and the product are in the correct positions.

[0053] At this point, the push-pull elbow clamp 212 needs to be manually pushed out into place, and the floating clamps on both sides will hold the product (e.g. Figure 6The floating clamp is equipped with positioning pins and product contouring parts. Additionally, it should be noted that one type of motor housing corresponds to one type of clamp. The flipping clamp assembly is equipped with two types of clamps suitable for the two types of housings of the dual motors. Therefore, the flipping device can flip not only the two types of motor housings individually but also the dual-motor assembly individually.

[0054] Finally, after the product is placed into the clamp, the flip clamp assembly is raised to a certain height, the transport trolley is removed from the equipment, and the handwheel is manually rotated to achieve a 360° flip of the housing, preparing for the next step of assembling the dual-motor drive assembly.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
