[0018] In view of the shortcomings of the prior art, this invention, through long-term research and extensive practice, has yielded the technical solution of this utility model. The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.
[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a three-dimensional structural view of a battery pack maintenance tooling mechanism provided in an embodiment of this utility model; Figure 2 This is a top view of the structure of a battery pack maintenance tooling mechanism provided in this embodiment of the utility model; Figure 3 This is a structural front view of a battery pack maintenance tooling mechanism provided in an embodiment of this utility model; Figure 4This is a rear view of the structure of a battery pack maintenance fixture mechanism provided in this embodiment of the utility model. The battery pack maintenance fixture mechanism is characterized by comprising a frame 1, a drive mechanism 2, a positioning mechanism 3, a running guide device 4, a cable chain 5, a mechanical gripper 6, a heavy-duty foot cup 7, a forklift limiting device 8, a universal ball joint 9, a guide wheel assembly 10, a cable chain mounting base 11, a guide mounting base 12, and a synchronous pulley 13. The frame 1 is a hollow square frame with two support frames 101. The two ends of the two support frames 101 are respectively fixed to two side frames along the length of the frame 1, dividing the length of the frame 1 into three equal parts. There are two sets of running guide devices 4, each consisting of a screw module 401, two sets of linear guide rail devices 402, and two sets of guide rail mounting bases 403. The two sets of running guide devices 4 are respectively installed along the length of the frame 1 on both sides of the inner side of the frame 1. The guide rail mounting base 403 is installed along the length of the frame 1, and its two ends are respectively fixed to the two side frames in the width direction of the frame 1. The linear guide rail device 402 is installed and fixed on the guide rail mounting base 403. The lead screw module 401 consists of a lead screw 4011 and a bearing seat 4012. The lead screw module 401 is installed along the length of the frame 1, and its two ends are respectively fixed to the two side frames in the width direction of the frame 1 through the bearing seats 4012. The cable chain mounting base 10 is installed in the middle of the frame 1 and located between the two sets of running guide devices 3. One end of the cable chain mounting base 10 is fixed to one side frame in the width direction of the frame 1, and the other end is fixed to the support frame 101. The cable chain 5 is assembled and fixed on the cable chain mounting base 11. Guide mounting bases 12 are fixedly assembled on both side frames in the length direction of the frame 1. The cable chain, together with the running guide device and the universal ball, completes the precise pulling and drawing of the battery pack.
[0020] One end of the lead screw module 401 passes through the bearing seat 4012 and is connected to the drive mechanism 2 via the synchronous pulley 13. Two sets of lead screw modules 401 in the two sets of running guide devices 4 are connected via the synchronous pulley 13. The drive mechanism 2 has two sets, which are assembled and fixed on one side of the frame 1 in the width direction. In actual use, after the battery pack is positioned and clamped by the mechanical grippers and positioning mechanism, the drive mechanism is activated. The drive mechanism drives the lead screw to run synchronously via the synchronous pulley. The lead screw drives the mechanical grippers to move back and forth on the linear guide device. The battery pack is then pulled out through the cooperation of the drag chain and the universal ball joint. The design of the synchronous pulley 13 effectively ensures the synchronous operation of the two sets of running guide devices, preventing the battery pack from shifting during disassembly and assembly due to asynchronous operation. There are two sets of mechanical grippers 6, which are slidably assembled with the lead screw module 401 and the linear guide device 402. The mechanical gripper 5 consists of a base 501 and grippers 502. The base 501 has a through hole on its side and a groove on its bottom. The mechanical gripper 5 is slidably assembled onto the linear guide rail device 402 via the groove on its bottom. It is also slidably assembled onto the screw module 401 via a lead screw 4011 passing through the through hole. The linear guide rail device 402 and the lead screw module 401 simultaneously guide and limit the upper and lower parts of the mechanical gripper 5, ensuring gripping accuracy. This ensures the accuracy of the battery pack's back-and-forth movement during disassembly and installation, guaranteeing the precision of battery pack disassembly and installation. Two sets of mechanical grippers 5 fix and clamp the two ends of one side of the battery pack, effectively ensuring the stability of the battery pack clamping. The universal ball 9 is assembled on top of the guide mounting base 12, and the guide wheel assembly 10 is assembled on the outer wall of the guide mounting base 12. The universal ball 9 and the guide wheel assembly 10 are staggered and do not interfere with each other, achieving smooth disassembly and installation of the battery pack.
[0021] The positioning mechanism 3 has two sets. The positioning mechanism 3 consists of a positioning base 301, a positioning bracket 302, and a positioning pin 303. The positioning bracket 302 is assembled on the positioning base 301. The positioning base 301 has a T-shaped structure. The positioning pin 303 has an adjustable assembly design and is assembled on the positioning bracket 302 by a nut. The extension length of the positioning pin 303 can be adjusted by the locking position of the nut. The positioning mechanism 3 is located inside the mechanical gripper 6. The positioning mechanism 3 sets the positioning point for limiting the position of the battery pack. In actual use, the extension length of the positioning pin 303 of the two sets of positioning mechanisms must be consistent. The two sets of positioning mechanisms 3 simultaneously position both ends of one side of the battery pack to ensure the overall positioning accuracy of the battery pack.
[0022] Preferably, the heavy-duty foot cup 7 is assembled at the bottom of the two side frames along the length of the frame.
[0023] Preferably, there are two sets of forklift limiting devices 8. The two ends of the forklift limiting devices 8 are respectively assembled and fixed to the bottom of the two side frames in the length direction of the frame 1. The forklift limiting device 8 consists of fork tooth fixing bolts 801 and fork tooth frame 802. In actual use, the forklift inserts the fork teeth into the fork tooth frame 802. By adjusting the length of the fixing bolts 801 extending into the fork tooth frame 802, the position of the forklift fork teeth is limited. The position of the tooling is adjusted by the forklift so that the battery pack on the tooling is aligned with the compartment to be assembled, so as to achieve precise assembly of the battery pack. The battery pack can also be precisely removed from the compartment or installation mechanism for maintenance.
