Description

Technical Field

[0001] This utility model relates to the field of tooling and lifting technology, and in particular to a tooling and lifting device for flipping battery modules. Background Technology

[0002] In the fields of new energy vehicles and energy storage, battery modules are core components. During the production, assembly, or repair of battery modules, they often need to be hoisted and their posture adjusted, especially by rotating them 180 degrees, to facilitate subsequent operations.

[0003] To meet this process requirement, various tooling and lifting devices for battery modules have emerged in the existing technology. These devices typically integrate clamping and lifting functions, and some are also designed with a flipping mechanism that allows the battery modules to be flipped in mid-air.

[0004] Existing flipping mechanisms typically use electric motors or hydraulic cylinders to drive a lifting frame around a central axis via a drive arm. However, battery modules are inherently large and heavy, generating significant inertial torque during the flipping process.

[0005] The applicant discovered in practice that existing tilting lifting devices exhibit poor dynamic stability when tilting heavily loaded battery modules. The lifting frame relies solely on the pivots at both ends for support and positioning; under the combined action of driving force and inertia, it is prone to lateral swaying and vertical movement during tilting. This unstable tilting not only reduces positioning accuracy and affects automated docking, but in severe cases, excessive swaying can damage the lifting device or battery modules, posing a safety hazard.

[0006] Therefore, this utility model proposes a tooling lifting device for flipping battery modules to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a tooling lifting fixture for battery module flipping, aiming to improve the problem that the lifting frame of the tooling lifting fixture for battery module flipping is unstable in posture during the flipping process, and is prone to shaking or displacement, resulting in inaccurate positioning. This utility model aims to provide a tooling lifting fixture for battery module flipping with an improved structure that can effectively solve the above problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a tooling lifting fixture for flipping battery modules, comprising: a base plate; a first support frame and a second support frame fixedly connected to the base plate, wherein the first support frame and the second support frame are respectively provided with a vertical guide groove and a horizontal guide groove; a lifting frame, wherein the lifting frame is rotatably connected between the first support frame and the second support frame via a rotating shaft; a support plate, wherein the support plate is fixedly connected to the base plate; a drive motor, wherein the drive motor is mounted on the support plate; a rotating column, wherein the output end of the drive motor is connected to the rotating column; a connecting plate; a connecting rod; a mounting cylinder, wherein the rotating column is connected to the mounting cylinder via the connecting plate and the connecting rod, and the mounting cylinder is fixedly connected to the side of the lifting frame that is offset from the rotating shaft; guide blocks, wherein the guide blocks are fixedly connected to both sides of the lifting frame, and the guide blocks are slidably connected in the vertical guide groove; and an anti-deviation slider, wherein the anti-deviation slider is also fixedly connected to the lifting frame, and the anti-deviation slider is slidably connected in the horizontal guide groove.

[0009] Preferably, the tooling lifting device for flipping the battery module further includes a crossbeam, which is connected to an external lifting device via a second connecting steel rope, and the crossbeam is also connected to the base plate via a first connecting steel rope and a fixing plate.

[0010] Preferably, a protective cover is provided on the hoisting frame, and a drive rod is installed on the protective cover; a bidirectional lead screw is provided inside the hoisting frame, and the drive rod is connected to and drives a synchronous pulley through a transmission mechanism. The synchronous pulley drives another synchronous pulley to rotate through a synchronous belt, and the two synchronous pulleys are coaxially connected to the bidirectional lead screw.

[0011] Preferably, a T-shaped slider is threaded onto the bidirectional lead screw, a clamping plate is fixedly connected to the T-shaped slider, and a stabilizing pad is fixedly connected to the side of the clamping plate facing the battery module.

[0012] Preferably, the rotating column is eccentrically connected to the connecting plate, and the connecting plate is rotatably connected to the connecting rod.

[0013] Preferably, the connecting rod is also rotatably connected to the inside of the mounting cylinder.

[0014] Preferably, the first support frame is provided with a positioning groove, and the mounting cylinder is inserted into the positioning groove after the hoisting frame is rotated 180 degrees.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting guide blocks on the hoisting frame and opening vertical guide grooves on the support frame, and simultaneously setting anti-deviation sliders on the hoisting frame and opening horizontal guide grooves on the support frame, the hoisting frame is constrained by both vertical and horizontal dimensions when it is flipped. This solves the problems of unstable posture, easy shaking and deviation, and inaccurate positioning of the hoisting frame during the flipping process in the prior art, and achieves the technical effect of extremely stable flipping process, accurate trajectory, and safety and reliability.

[0016] 2. This utility model uses a drive rod to drive a synchronous belt, which in turn drives two bidirectional lead screws to rotate synchronously, driving the T-shaped slider and the clamping plate to achieve synchronous clamping. This solves the problem of uneven clamping force or unstable clamping of battery modules in the prior art, achieving the technical effects of uniform force on both sides, stable clamping, convenient operation, and effective protection of battery modules from damage.

[0020] Please refer to Figures 1 to 5 This utility model provides a tooling lifting device for flipping battery modules, which aims to solve the problem in the prior art where the lifting frame is unstable in posture during the flipping process, is prone to shaking or displacement, and results in inaccurate positioning. like Figure 1 and Figure 2 As shown, the tooling for flipping battery modules includes a base plate 1, and a first support frame 2 and a second support frame 201 fixedly connected to the base plate 1.

Guide blocks 210 are fixedly connected to both sides of the lifting frame 202, and the guide blocks 210 are slidably connected within the vertical guide grooves. Anti-deviation sliders 7 are also fixedly connected to the lifting frame 202, and the anti-deviation sliders 7 are slidably connected within the horizontal guide grooves. The lifting device also includes a support plate 204, which is fixedly connected to the base plate 1; a drive motor 205 is mounted on the support plate 204, and the output end of the drive motor 205 is connected to a rotating column 206; a connecting plate 209 is eccentrically connected to the rotating column 206, and the connecting plate 209 is rotatably connected to the connecting rod 208. The connecting rod 208 is also rotatably connected to the inside of the mounting cylinder 207, and the mounting cylinder 207 is fixedly connected to the side of the lifting frame 202 that is offset from the axis of rotation of the lifting frame 202; a positioning groove 203 is provided on the first support frame 2, and the mounting cylinder 207 is inserted into the positioning groove 203 after the lifting frame 202 is rotated 180 degrees.

[0021] To secure the battery module, a protective cover 4 is installed on the lifting frame 202, and a drive rod 5 is mounted on the protective cover 4. A bidirectional lead screw 3 is installed inside the lifting frame 202. The drive rod 5 is connected to a synchronous pulley 303 through a transmission mechanism. The synchronous pulley 303 is connected to another synchronous pulley 303 through a synchronous belt 304. The two synchronous pulleys 303 are coaxially fixedly connected to the bidirectional lead screw 3. A T-shaped slider 301 is threaded onto the bidirectional lead screw 3. A clamping plate 302 is fixedly connected to the T-shaped slider 301. A stabilizing pad 6 is fixedly connected to the side of the clamping plate 302 facing the battery module.

[0022] In a preferred embodiment, the tooling lifting device also includes a crossbeam 9, which is connected to an external lifting device via a second connecting steel rope 11. The crossbeam 9 is also connected to the base plate 1 via a first connecting steel rope 10 and a fixing plate 8. In one preferred embodiment, the rotating column 206 is eccentrically connected to a connecting plate 209, and the connecting plate 209 is rotatably connected to the connecting rod 208; In a preferred embodiment, the connecting rod 208 is also rotatably connected to the inside of the mounting cylinder 207; In one preferred embodiment, the first support frame 2 is provided with a positioning groove 203, and the mounting cylinder 207 is inserted into the positioning groove 203 after the hoisting frame 202 is rotated 180 degrees.

[0023] Working principle: When it is necessary to clamp the battery module, the battery module is first placed inside the lifting frame 202. Then, the drive rod 5 installed on the protective cover 4 is rotated. The drive rod 5 drives the synchronous wheel 303 to rotate through the transmission mechanism. The synchronous wheel 303 then drives another synchronous wheel 303 to rotate synchronously through the synchronous belt 304. The two synchronous wheels 303 drive the bidirectional lead screw 3 to rotate. Since the bidirectional lead screw 3 is threadedly connected to the T-shaped slider 301, the T-shaped slider 301 will drive the fixed clamping plate 302 to move towards each other until the stabilizing pad 6 fixed on the clamping plate 302 contacts the outer wall of the battery module and clamps it in place. When hoisting is required, the external hoisting equipment is connected to the second connecting steel rope 11. The hoisting force is transmitted to the base plate 1 through the crossbeam 9, the first connecting steel rope 10 and the fixing plate 8 in sequence, thereby lifting the entire tooling hoist together with the battery module smoothly. When flipping is required, the drive motor 205 mounted on the support plate 204 is activated. The output end of the drive motor 205 drives the rotating column 206 to rotate. The rotating column 206, through the eccentrically connected connecting plate 209, the rotatably connected connecting rod 208, and the mounting cylinder 207 fixedly connected to the lifting frame 202, forms a crank-connecting rod mechanism, which converts the rotational motion of the motor into a pushing or pulling force on the lifting frame 202, causing the lifting frame 202 to rotate around its axis relative to the first support frame 2 and the second support frame 201. During the rotation process, Guide blocks 210, fixedly connected to both sides of the lifting frame 202, slide within the vertical guide grooves of the first support frame 2 and the second support frame 201 to guide and limit the rotation trajectory of the lifting frame 202. Simultaneously, anti-deviation sliders 7, fixedly connected to the lifting frame 202, slide within the horizontal guide groove to improve the stability of the rotation process and prevent the lifting frame 202 from swaying laterally. When the lifting frame 202 rotates 180 degrees, the mounting cylinder 207 engages with the positioning groove 203 on the first support frame 2 to achieve precise positioning.
