Description

Technical Field

[0001] This utility model relates to the field of STM composite material battery pack shell processing, specifically an STM composite material battery pack shell laser cutting device. Background Technology

[0002] Laser cutting is commonly used for the cutting and processing of STM composite battery pack housings. However, existing laser cutting equipment has limited tooling positions, making it inconvenient to secure large STM composite battery pack housings. Furthermore, single-cylinder-powered tooling structures can only perform vertical movement for separation or pressing, failing to automatically rotate the contact pressing parts horizontally, thus hindering the smooth removal of the workpiece. Therefore, this paper proposes a laser cutting device for STM composite battery pack housings to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a laser cutting device for STM composite material battery pack casing in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a laser cutting device for STM composite material battery pack housing, including a laser cutting gun and a clamping mechanism for positioning the battery pack housing tooling. The laser cutting gun is disposed above the tooling table, and multiple clamping mechanisms are distributed at corresponding positions on the tooling table. Each of the clamping mechanisms includes a cylinder, a short rod, a first bevel gear, a second bevel gear, a transmission gear, a rack, a square rod, a piston rod, a pressure rod, and a contact block. A channel is provided in the middle of the piston rod on the cylinder, and a piston rod is slidably installed inside the channel. The top end of the piston rod is connected to one end of the square rod, and the other end of the square rod is connected to the bottom end of the rack via a connector. The rack meshes with the transmission gear, which is mounted on one side of the transmission rod. The second bevel gear on the other side of the transmission rod meshes with the first bevel gear at the bottom end of the short rod. The top end of the short rod is fixedly connected to one end of the pressure rod, and a contact block is installed at the bottom of the other end of the pressure rod.

[0005] Preferably, the transmission rod is rotatably mounted inside the circular box, and the top center of the circular box is rotatably connected to the middle of the short rod via a bearing.

[0006] Preferably, the bottom center of the circular box is connected to the channel port located at the top center of the piston rod through a square hole, and the bottom edge of the circular box and the top edge of the piston rod are fixedly connected to each other.

[0007] Preferably, the inside of the square hole is in sliding contact with the corresponding surface of the square rod, and a spring is installed inside the square hole.

[0008] Preferably, the spring is fitted onto the square rod portion located inside the circular box.

[0009] Preferably, the channel is connected to a corresponding part inside the cylinder.

[0010] Compared with the prior art, the advantages of this utility model are as follows: by inflating or deflating the cylinder, the piston rod located inside the channel is pushed and pulled. Combined with the transmission connection between the rack, transmission gear, transmission rod, second bevel gear, and first bevel gear, the short rod and the contact pressure block connected by the pressure rod can be automatically rotated to be above the pressure position or moved to one side away from the pressure position. This enhances the automatic adjustment of the positioning clamping and replaces the method of manually pushing and pulling the contact pressure blocks one by one. It solves the inconvenience of manually adjusting the contact pressure position one by one due to the many clamping and fixing parts of the battery pack shell, and improves the efficiency of cutting tooling processing.

[0017] Please see Figure 1-4 As shown, an STM composite material battery pack shell laser cutting device includes a laser cutting gun 1 and a clamping mechanism 2 for tooling positioning of the battery pack shell 4. The laser cutting gun 1 is disposed above the tooling table 3, and multiple clamping mechanisms 2 are distributed at corresponding positions on the tooling table 3. Each of the clamping mechanisms 2 includes a cylinder 210, a short rod 221, a first bevel gear 222, a second bevel gear 223, a transmission gear 225, a rack 226, a square rod 227, a piston rod 229, a pressure rod 230, and a contact pressure block 240. A channel 211a is provided in the middle of the piston rod 211 on the cylinder 210, and the piston rod 229 is slidably installed inside the channel 211a. The top end of the piston rod 229 is connected to one end of the square rod 227. 27 The other end is connected to the bottom end of the rack 226 via a connector. The rack 226 meshes with the transmission gear 225. The transmission gear 225 is mounted on one side of the transmission rod 224. The second bevel gear 223 located on the other side of the transmission rod 224 meshes with the first bevel gear 222 located at the bottom end of the short rod 221. The top end of the short rod 221 is fixedly connected to one end of the pressure rod 230, and a contact pressure block 240 is installed at the bottom of the other end of the pressure rod 230.

[0018] The transmission rod 224 is rotatably mounted inside the circular box 220, and the top center of the circular box 220 is rotatably connected to the middle of the short rod 221 via a bearing. The bottom center of the circular box 220 is connected to the port of the channel 211a located at the middle of the top of the piston rod 211 via a square hole. The bottom edge of the circular box 220 is fixedly connected to the top edge of the piston rod 211. The inside of the square hole is in sliding contact with the corresponding surface of the square rod 227, and a spring 228 is installed inside the square hole. The spring 228 is fitted onto the part of the square rod 227 located inside the circular box 220.

[0019] The channel 211a is connected to the corresponding internal part of the cylinder 210.

[0020] Working principle: The battery pack housing 4 is placed on the tooling table 3, and the battery pack housing 4 is clamped and fixed by the distributed clamping mechanisms 2. At this time, the laser cutting gun 1 is run to cut the battery pack housing 4. Clamping mechanism 2: When the cylinder 210 is in the inflated and extended state, the inflated gas enters the orifice 211a and pushes the piston rod 229 upward, causing the square rod 227 and rack 226 connected to it to move upward, thereby driving the transmission gear 225 to rotate, and further driving the second bevel gear 223, the first bevel gear 222 and the short rod 221 to rotate. At the same time, the cylinder 210 continues to extend, which is beneficial for the pressure rod 230 and the contact pressure block 240 to rotate outward and disengage from the contact pressing part on the battery pack housing 4. When the cylinder 210 is in the exhaust and retraction state, the cylinder 210 is operated in the opposite way to the above-mentioned inflation and extension linkage, which helps to rotate the pressure rod 230 and the contact pressure block 240 inward to approach the contact pressing part that contacts the battery pack housing 4. Compared with the existing technology, the difference is that the piston rod 229 located inside the channel 211a is pushed and pulled by the internal inflation or deflation of the cylinder 210. Combined with the transmission connection between the rack 226, the transmission gear 225, the transmission rod 224, the second bevel gear 223, and the first bevel gear 222, the short rod 221 and the contact pressure block 240 connected by the pressure rod 230 can be automatically rotated to be above the pressure position or moved away from the pressure position to one side. This enhances the automatic adjustment of the positioning clamping and replaces the method of manually pushing and pulling the contact pressure blocks 240 one by one. It solves the inconvenience of manually adjusting the position of the contact pressure blocks 240 one by one due to the many clamping and fixing parts of the battery pack housing 4, and improves the efficiency of cutting tooling processing.
