Detailed Implementation

[0017] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Please see Figure 1-4 This embodiment provides a technical solution: a fixing device for processing sheet metal parts of a battery box, including a frame 1, a PLC controller 2 installed on the side of the frame 1, a position adjustment mechanism 5 installed on the inner side of the frame 1, a first lifting mechanism 3 and a second lifting mechanism 4 respectively installed on the adjustment part of the position adjustment mechanism 5, a contour pressing unit 7 installed on the lifting part of the first lifting mechanism 3, and a sheet metal adsorption fixing unit 6 installed on the lifting part of the second lifting mechanism 4, and the PLC controller 2 is electrically connected to an external power supply.

[0019] The conformal clamping unit 7 presses the curved part of the battery box sheet metal part, and the sheet metal part adsorption and fixing unit 6 adsorbs and fixes the flat position of the battery box sheet metal part. The fixing method can be selected, avoiding the drawback of traditional fixtures that need to be designed separately for different battery box models, and has good compatibility.

[0020] The position adjustment mechanism 5 includes a linear motor 51 and a guide rail 52. The end of the guide rail 52 is fixedly connected to the frame 1. The linear motor 51 is mounted on the guide rail 52. There are three sets of linear motors 51. The linear motors 51 are electrically connected to the PLC controller 2. The linear motors 51 move linearly on the guide rail 52. The linear motors 51 drive the first lifting mechanism 3 and the second lifting mechanism 4 to move, thereby adjusting the working position of the sheet metal adsorption and fixing unit 6 and the contour pressing unit 7, so that they are moved to the position corresponding to the plane or curved surface of the battery box sheet metal part. The adjustment is convenient and easy to use.

[0021] The first lifting mechanism 3 has two sets, which are located at the bottom of two sets of linear motors 51 located on the side. The first lifting mechanism 3 includes a first electric push rod 31 and a first mounting base 32. The first electric push rod 31 is installed at the bottom of the two sets of linear motors 51 located on the side, and the first mounting base 32 is installed at the telescopic end of the first electric push rod 31. The first electric push rod 31 is electrically connected to the PLC controller 2. The contour pressing unit 7 includes a positioning rod 71, a spring 72, and a connecting block 73. The positioning rod 71 is evenly arranged on the first mounting base 32 and is vertically movably connected to the first mounting base 32. The connecting block 73 is fixed to the top of the positioning rod 71 and is connected to the first mounting base 32 through the spring 72. The second lifting mechanism 4 includes a second electric push rod 41 and a second mounting base 42. The moving push rod 41 is installed at the bottom of the linear motor 51 located in the middle. The second mounting base 42 is fixed to the telescopic end of the second electric push rod 41. The second electric push rod 41 is electrically connected to the PLC controller 2. The telescopic end of the first electric push rod 31 drives the first mounting base 32 to move up and down, thereby adjusting the working height of the contour pressing unit 7. The positioning rod 71 is pressed against the curved surface of the battery box sheet metal part. Then, the positioning rod 71 moves up and down with the first mounting base 32 to adapt to the curved surface change of the battery box sheet metal part. At this time, the connecting block 73 at the end of the positioning rod 71 compresses the spring 72, and the spring 72 produces elastic deformation. The deformation force of the spring 72 reacts to the positioning rod 71, thereby pressing the positioning rod 71 against the curved surface of the battery box sheet metal part. It has a good fixing effect and is easy to use.

[0022] The sheet metal part adsorption and fixing unit 6 includes a vacuum suction cup 61, a vacuum tube 62, and a vacuum pump 63. The vacuum pump 63 is installed inside the second mounting base 42, and the vacuum suction cup 61 is located at the bottom of the second mounting base 42. The vacuum suction cup 61 is connected to the vacuum pump 63 through the vacuum tube 62. The vacuum pump 63 is electrically connected to the PLC controller 2. The telescopic end of the second electric push rod 41 drives the second mounting base 42 to move up and down, thereby adjusting the working height of the sheet metal part adsorption and fixing unit 6. The vacuum pump 63 provides vacuum adsorption force to the vacuum suction cup 61 through the vacuum tube 62. The vacuum suction cup 61 adsorbs and fixes the flat position of the battery box sheet metal part, which is convenient to fix and easy to use.

[0023] The working principle of the fixing device for processing sheet metal parts of battery boxes provided by this utility model is as follows: The linear motor 51 moves linearly on the guide rail 52, and the linear motor 51 drives the first lifting mechanism 3 and the second lifting mechanism 4 to move, thereby adjusting the working position of the sheet metal adsorption fixing unit 6 and the contour pressing unit 7, so that they move to the position corresponding to the plane or curved surface of the sheet metal part of the battery box. The telescopic end of the first electric push rod 31 drives the first mounting base 32 to move up and down, thereby adjusting the working height of the contour pressing unit 7. The positioning rod 71 presses against the curved surface of the sheet metal part of the battery box. Then, the positioning rod 71 is connected to the first mounting base 32 to move up and down. The first mounting base 32 moves up and down to adapt to the curved surface changes of the battery box sheet metal parts. At this time, the connecting block 73 at the end of the positioning rod 71 compresses the spring 72, causing the spring 72 to undergo elastic deformation. The deformation force of the spring 72 reacts to the positioning rod 71, thereby pressing the positioning rod 71 tightly onto the curved surface of the battery box sheet metal parts. The telescopic end of the second electric push rod 41 drives the second mounting base 42 to move up and down, thereby adjusting the working height of the sheet metal parts adsorption and fixing unit 6. The vacuum pump 63 provides vacuum adsorption force to the vacuum suction cup 61 through the vacuum tube 62, and the vacuum suction cup 61 adsorbs and fixes the planar position of the battery box sheet metal parts.
