Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for battery box assembly. Background Technology

[0002] Battery box assembly tooling fixtures mainly serve the manufacturing process of power battery boxes, such as the casing of power batteries for new energy vehicles and energy storage battery boxes. They cover processes such as welding, assembly, testing, and handling. Battery boxes are mostly simple metal shells that rely on general-purpose fixtures for fixing to meet basic production needs.

[0003] However, in the existing technology, existing tooling fixtures usually rely on a single reference surface or simple locating pins, without taking into account the slight deformation of the battery box caused by processing errors. This leads to a deviation between the actual positioning and the theoretical reference, making it impossible to quickly and accurately perform positioning and clamping, thus affecting the assembly accuracy with the battery cell module. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing tooling fixtures usually rely on a single reference surface or simple positioning pins, without considering the slight deformation of the battery box caused by processing errors, resulting in deviation between actual positioning and theoretical reference, making it impossible to quickly and accurately perform positioning and clamping, thus affecting the assembly accuracy with the battery cell module. Therefore, a tooling fixture for battery box assembly is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tooling fixture for battery box assembly, comprising a base plate, a clamping mechanism mounted on the top surface of the base plate, two sets of the clamping mechanism, a supporting mechanism mounted at the center of the top surface of the base plate, the clamping mechanism comprising a fixed plate, a support plate, a servo motor, a guide plate, a gear, and a toothed plate, the bottom surface of the fixed plate being fixedly connected to the bottom surface of the base plate, two sets of the support plate being provided, the two sets of support plates being movably connected to both ends of the fixed plate, the servo motor being mounted on the outer wall of the support plate, the guide plate being fixedly connected to the top surface of the support plate, the gear being fixedly connected to the output shaft end of the servo motor, the toothed plate being movably connected to one side of the support plate, the gear meshing with the toothed plate, and a positioning plate being provided on one side of the clamping mechanism, the bottom surface of the positioning plate being fixedly connected to the top surface of the base plate.

[0006] Preferably, a fixing block is fixedly connected to the top surface of the fixing plate, and lead screws are rotatably connected to both outer walls of the fixing block, with an adjustment knob fixedly connected to the end of the lead screw.

[0007] Preferably, the support plate is movably connected to the top surface of the fixed plate, and the support plate is threaded onto the outer wall of the lead screw.

[0008] Preferably, a guide rod is installed on one outer wall of the support plate, and a slider is movably sleeved on the outer wall of the guide rod. The top end of the slider is fixedly connected to the side wall of the toothed plate.

[0009] Preferably, the supporting mechanism includes a support plate and a cylinder, with the center of the bottom surface of the support plate fixedly connected to the top surface of the cylinder telescopic rod.

[0010] Preferably, the bottom surface of the cylinder is fixedly connected to the top surface of the base plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the battery box is stably clamped by the gear and toothed plate driven by the servo motor. The positioning plate at the end restricts the axial displacement of the battery box, and the radial clamping on both sides restricts the battery box to perform rapid center positioning, improves clamping accuracy, and ensures the subsequent assembly accuracy with the battery cell module.

[0012] 2. In this utility model, the screw rods on both sides of the fixed block and the adjustment knob form a manual adjustment mechanism. Rotating the knob can drive the support plate to move horizontally along the top surface of the fixed plate, so that the distance between the two sets of clamping mechanisms can be continuously adjusted within a certain range. This can adapt to battery boxes with large length differences, solve the problem of changing the type of traditional clamps and shorten the changeover time. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a tooling fixture for battery box assembly, including a base plate 1. A clamping mechanism 2 is installed on the top surface of the base plate 1. The clamping mechanism 2 is provided in two sets. A support mechanism 3 is installed at the center of the top surface of the base plate 1. The clamping mechanism 2 includes a fixed plate 21, a support plate 22, a servo motor 23, a guide plate 24, a gear 25, and a toothed plate 26. The bottom surface of the fixed plate 21 is fixedly connected to the bottom surface of the base plate 1. The support plate 22 is provided in two sets. The two sets of support plates 22 are movably connected to both ends of the fixed plate 21, respectively. The servo motor 23 is installed on the outer wall of the support plate 22. The guide plate 24 is fixedly connected to the top surface of the support plate 22. The gear 25 is fixedly connected to the output shaft end of the servo motor 23. The toothed plate 26 is movably connected to one side of the support plate 22. The gear 25 and the toothed plate 26 are meshed. A positioning plate 4 is provided on one side of the clamping mechanism 2. The bottom surface of the positioning plate 4 is fixedly connected to the top surface of the base plate 1.

[0018] The specific settings and functions of this embodiment are described in detail below. The gear 25 and toothed plate 26 driven by the servo motor 23 achieve stable clamping of the battery box. The torque output by the servo motor 23 is transmitted to the toothed plate 26 through the gear 25, causing the toothed plate 26 to move in a straight line. The two sets of symmetrically arranged clamping mechanisms 2 can exert force synchronously from both sides of the battery box to ensure uniform clamping force and avoid deformation caused by force on one side. The positioning plate 4 at the end restricts the axial displacement of the battery box. The radial clamping on both sides restricts the battery box to perform rapid center positioning and improves clamping accuracy. The guide plate 24 facilitates better placement of the battery box between the two sets of support plates 22.

[0019] Example 2: Figure 1 - Figure 4 As shown, a fixing block 27 is fixedly connected to the top surface of the fixing plate 21. A lead screw 28 is rotatably connected to both outer walls of the fixing block 27. An adjustment knob 29 is fixedly connected to the end of the lead screw 28. A support plate 22 is movably connected to the top surface of the fixing plate 21. The support plate 22 is threaded onto the outer wall of the lead screw 28. A guide rod 262 is installed on one outer wall of the support plate 22. A slider 261 is movably sleeved on the outer wall of the guide rod 262. The top of the slider 261 is fixedly connected to the side wall of the toothed plate 26. The supporting mechanism 3 includes a support plate 31 and a cylinder 32. The center of the bottom surface of the support plate 31 is fixedly connected to the top surface of the telescopic rod of the cylinder 32. The bottom surface of the cylinder 32 is fixedly connected to the top surface of the base plate 1.

[0020] The overall effect of this embodiment is that the lead screws 28 on both sides of the fixed block 27 and the adjustment knob 29 form a manual adjustment mechanism. Rotating the knob can drive the support plate 22 to move horizontally along the top surface of the fixed plate 21, so that the distance between the two sets of clamping mechanisms 2 can be continuously adjusted within a certain range, which can adapt to battery boxes with large length differences. This solves the problem of changing the type of traditional clamps and shortens the changeover time. The toothed plate 26 is connected to the guide rod 262 through the slider 261, so that the movement trajectory of the toothed plate 26 is strictly parallel to the axis of the guide rod 262, improving the clamping accuracy and stability. The cylinder 32 drives the support plate 31 to achieve vertical lifting and lowering, which can automatically adjust the support position according to the height of the battery box, ensuring that the contact point between the support plate 31 and the bottom surface of the battery box is always directly below the center of gravity, improving the support stability.

[0021] The usage and working principle of this device are as follows: According to the length of the battery box to be processed, rotate the adjustment knob 29, and drive the support plate 22 to move horizontally on the fixed plate 21 through the lead screw 28, so that the initial distance between the two sets of clamping mechanisms 2 is slightly greater than the length of the battery box; according to the height of the battery box, adjust the support height of the support plate 31 through the cylinder 32 to make it flush with the reference surface of the bottom of the battery box, and hoist the battery box onto the support plate 31. Push one side of the battery box to fit against the reference surface of the positioning plate 4 to complete the initial positioning. Start the servo motor 23, and the gear 25 drives the toothed plate 26 to move along the guide plate 24 and the guide rod 262 to the side of the battery box. The toothed plates 26 on both sides tighten synchronously until the clamping force reaches the preset value. The servo motor 23 current feedback control is used to avoid over-clamping.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
