Description

Technical Field

[0001] The present invention relates to the technical field of automobile production, and more particularly to a punching device for manufacturing a battery case of a new energy vehicle. Background Art

[0002] The development of modern new energy vehicles has promoted the rapid progress of battery technology. As an important part of the battery assembly, the manufacturing quality of the battery case directly affects the battery performance and safety. The battery case usually needs to go through precise punching processes to install battery cells or other battery components;

[0003] Traditional punching devices for manufacturing battery cases usually use a single clamping device to clamp a single battery case, and the power transmission of a single electric push rod is carried out through a traditional mechanical drive structure to achieve the positioning and processing of the battery case. However, this single clamping method has the following problems;

[0004] Firstly, since the single clamping device can only process one battery case at a time, the production efficiency is low and the manufacturing cycle is long, which cannot meet the requirements of modern large-scale production;

[0005] Secondly, the traditional punching device needs to move and adjust the drill bit to position the punching location, and the positioning time is long, wasting a large amount of time cost;

[0006] Finally, when the drill bit punches the battery case, the rotation of the drill bit may drive the battery case to shift, which will affect the subsequent assembly quality of the battery case, and there is great inconvenience;

[0031] In this embodiment, by providing the clamping members 3 arranged regularly, the transmission shaft 4, and the transmission track 5, it is beneficial to drive the transmission track 5 to operate through the transmission shaft 4 when punching the battery case, so that the transmission track 5 drives the regularly arranged clamping members 3, and then the battery case clamped by the regularly arranged clamping members 3 is moved, so that multiple battery cases can be punched simultaneously, thereby increasing the work efficiency and reducing the production cycle.

[0032] Among them, limiting chutes 201 are provided on both sides of the surface of the guiding track 2, and the bottoms of the clamping members 3 are movably clamped inside the limiting chutes 201.

[0033] Among them, punching drills 801 are provided at the bottom positions of the hydraulic cylinders 8, and the hydraulic cylinders 8 are fixedly connected to the bottom position of the mounting table 7 through bolts.

[0034] Among them, a circular mounting hole 901 is provided at the position where the fixed bracket 9 is fixedly connected to the servo motor 10.

[0035] Among them, regularly arranged mounting heads 501 are provided on the surface of the transmission track 5 at the positions where the clamping members 3 are fixedly connected.

[0036] Among them, the clamping member 3 includes a battery case fixing table 301. A docking head 302 is provided on one side of the battery case fixing table 301 close to the transmission track 5. A docking rod 303 is movably connected inside the docking head 302. The clamping member 3 is fixedly connected to one side of the surface of the transmission track 5 through the docking rod 303.

[0037] Among them, limiting components 304 are fixedly connected to both sides of the surface of the battery case fixing table 301.

[0038] Among them, the clamping component 11 includes a clamping push rod 1101. A clamping plate 1102 is fixedly connected to one end of the clamping push rod 1101 inside the clamping member 3. A feeding push surface 1103 is provided at one end of the clamping plate 1102. A clamping spring 12 is movably sleeved on the surface of the clamping push rod 1101.

[0039] Working principle of the present invention: First, when preparing to punch holes in the battery case, the hydraulic cylinder 8 is first positioned according to the punching reserved hole 305 opened in the clamping member 3, and then the positioned hydraulic cylinder 8 is fixed to the bottom position of the mounting table 7 by bolts. At this time, the punching drill bit 801 is driven by the hydraulic cylinder 8 to approach the punching reserved hole 305 at the predetermined position. Then, after the test is completed, the battery case to be punched is picked up and approached to the top position of the battery case fixing table 301. Then, the battery case is pushed so that it presses the feeding pushing surface 1103. Then, the clamping plate 1102 presses the clamping spring 12 on the surface of the clamping push rod 1101 due to the extrusion. At this time, the clamping plate 1102 enters the internal position of the clamping groove 306 opened in the battery case fixing table 301. Then, under the reaction force of the clamping spring 12, the clamping plate 1102 fixes and clamps the battery case at the internal position of the battery case fixing table 301. Then, all the battery cases to be punched are placed at the internal position of the battery case fixing table 301 according to the above description;

[0040] Then, the servo motor 10 inside the circular mounting hole 901 opened in the fixed bracket 9 is started. At this time, the servo motor 10 runs and drives the transmission shaft 4 to rotate inside the working machine tool 1. Then, the rotation of the transmission shaft 4 drives the transmission track 5 to operate. Then, the operation of the transmission track 5 drives the entire clamping member 3 fixed at the mounting head 501 position. At this time, the clamping member 3 moves smoothly under the restriction of the guiding track 2. Then, when the clamping member 3 reaches the predetermined position, the hydraulic cylinder 8 is started, so that the hydraulic cylinder 8 drives the punching drill bit 801 to descend. Then, the punching drill bit 801 punches the battery case inside the battery case fixing table 301 and enters the internal position of the predetermined punching reserved hole 305. Then, after the punching is completed, the punching drill bit 801 is reset. Then, the servo motor 10 is started again to drive the transmission track 5. Then, the transmission track 5 drives the clamping member 3 to move. At this time, the bottom limit block 307 of the battery case fixing table 301 is restricted by the guiding track 2 and assisted by the auxiliary pulley 308. Thus, the clamping member 3 moves smoothly on the top of the guiding track 2 to the discharging position, and then the punched battery case at the top of the clamping member 3 is pulled out.

[0041] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
