[0003] Based on existing solutions and actual production and processing, the current tooling for welding battery box housings still has some problems, such as:

[0004] 1. When fixing the battery box housing, it is usually only possible to fix a battery box housing of a single size. In actual use, the scope of application for fixing a battery box housing of a single size is relatively limited.

[0005] 2. The ordinary tooling used for welding battery box housings does not perform well in calibrating the battery box housings, thus affecting the welding effect of the battery box housings;

[0006] 3. Welding the battery box housing is not convenient enough. Therefore, this utility model provides a tooling for welding battery box housing with calibration function to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a welding fixture for battery box housing with calibration function, so as to solve the problem mentioned in the background art that when fixing battery box housing, it can usually only fix battery box housing of a single size. In actual use, the scope of application for fixing battery box housing of a single size is relatively limited. Ordinary battery box housing welding fixtures have poor calibration effect on battery box housing, thus affecting the welding effect of battery box housing and making the welding of battery box housing inconvenient.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for battery box housing with calibration function, including a base, on the middle side of its left end, with a connecting plate fixedly installed;

[0009] Also includes:

[0010] The motor is fixedly mounted on the left side of the connecting plate, and a connecting wheel is fixedly connected to the right side of the motor. A connecting wheel is movably connected to the upper side of the connecting wheel, and a movable plate is fixedly mounted on the right side of the connecting wheel. An mounting plate is fixedly mounted on the upper inner side of the movable plate, and a mounting rod is movably connected to the outer side of the middle part of the movable plate. A moving block is movably connected to the outer side of the mounting rod, and an mounting block is fixedly mounted on the inner side of the moving block. A clamping structure is movably connected to the front inner side of the mounting block, and a buffer pad is fixedly mounted on the rear inner side of the mounting block. A calibration block is fixedly mounted on the right rear end of the mounting block.

[0011] A fixing plate is fixedly installed on the upper side inside the base, and a fixing frame is fixedly installed on the upper side of the fixing plate. A first cylinder is fixedly installed on the upper side inside the fixing frame, and a connecting block is fixedly installed on the front side of the first cylinder. A second cylinder is fixedly installed on the lower side of the connecting block, and a welding gun is fixedly installed on the lower side of the second cylinder.

[0012] Preferably, the front cross-sectional shape of the calibration block is inclined.

[0013] Preferably, the connecting wheel and the connecting plate are connected by rotation, and the vertical cross-section of the connecting plate is an "L" shaped structure.

[0014] Preferably, the connecting wheel and the driving wheel are connected by meshing and rotate the mounting plate.

[0015] Preferably, the mounting rod and the movable plate are connected by rotation, and the mounting rod and the moving block are connected by threads.

[0016] Preferably, the clamping structure includes a movable rod that is movably connected to the front end of the mounting block, and a connecting block is movably connected to the rear side of the movable rod, with a protective pad fixedly installed on the rear side of the connecting block.

[0017] Preferably, the movable rod and the mounting block are connected by a thread, and the movable rod is connected to the connecting block through a bearing.

[0018] Preferably, the connecting block and the mounting block are connected by a sliding manner, and the mounting blocks are symmetrically distributed about the center line of the mounting plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the welding fixture for battery box housing with calibration function is convenient for fixing battery box housings of different sizes, convenient for calibrating battery box housings, and has a good welding effect on battery box housings;

[0020] 1. By placing the battery box housing inside the mounting block and rotating the moving rod, the moving rod is threaded to the front center of the mounting block. This causes the connecting block, which is connected to the moving rod via a bearing, to slide backward inside the mounting block. This allows the connecting block to move the protective pad and buffer pad to clamp the battery box housing, making it easy to fix battery box housings of different sizes.

[0021] 2. By rotating the mounting rod, the mounting rod rotates on the outer side of the upper end of the movable plate, causing the moving block, which is threadedly connected to the mounting rod, to slide inward from the outer side of the middle of the mounting plate. This causes the moving block to drive the mounting block to slide inward inside the mounting plate, which in turn causes the mounting block to drive the battery box housing to slide inward. This allows the mounting block to drive the calibration block to slide and position behind the mounting block on the other side, facilitating the calibration of the battery box housing.

[0022] 3. By activating the second cylinder, the welding gun slides downwards to perform spot welding on the front side of the battery box housing. Activating the first cylinder causes the connecting block to slide back and forth inside the fixed frame, thus moving the welding gun to the rear side of the battery box housing. Activating the second cylinder causes the welding gun to slide downwards to perform spot welding on the rear side of the battery box housing. Activating the motor causes the connecting wheel to rotate on the right side of the connecting plate, thus rotating the connecting wheel that meshes with the connecting wheel, which in turn drives the movable wheel... The movable plate rotates 180°, causing the mounting plate to rotate as well. This flips the battery box housing over. The second cylinder is then activated, causing the welding gun to slide downwards and perform spot welding on the front side of the battery box housing. The first cylinder is then activated, causing the connecting block to slide back and forth inside the fixed frame. This moves the welding gun to the rear side of the battery box housing. The second cylinder is then activated, causing the welding gun to slide downwards and perform spot welding on the rear side of the battery box housing. This process ensures a good welding effect on the battery box housing. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-8This utility model provides a technical solution: a welding fixture for a battery box housing with calibration function, comprising: a connecting plate 9 fixedly installed on the middle left side of a base 1; a motor 10 fixedly installed on the middle left side of the connecting plate 9; a connecting wheel 11 fixedly connected to the right side of the motor 10; a connecting wheel 12 movably connected to the upper side of the connecting wheel 11; a movable plate 2 fixedly installed on the right side of the connecting wheel 12; an mounting plate 3 fixedly installed on the inner upper end of the movable plate 2; a mounting rod 13 movably connected to the outer middle part of the movable plate 2; a moving block 4 movably connected to the outer side of the mounting rod 13; a mounting block 5 fixedly installed on the inner side of the moving block 4; a clamping structure movably connected to the front inner side of the mounting block 5; and a buffer pad fixedly installed on the rear inner side of the mounting block 5. 20, and a calibration block 6 is fixedly installed on the right rear end of the mounting block 5. The battery box housing is placed inside the mounting block 5. The clamping structure is rotated so that the clamping structure and the buffer pad 20 clamp the battery box housing, which is convenient for fixing battery box housings of different sizes. The mounting rod 13 is rotated so that the mounting rod 13 rotates on the outer side of the upper end of the movable plate 2, so that the moving block 4 connected to the mounting rod 13 slides inward on the outer side of the middle of the mounting plate 3, and then the moving block 4 drives the mounting block 5 to slide inward inside the mounting plate 3, so that the mounting block 5 drives the battery box housing to slide inward, so that the mounting block 5 drives the calibration block 6 to slide and position on the rear side of the mounting block 5 on the other side, which is convenient for calibrating the battery box housing.

[0034] A fixing plate 7 is fixedly installed on the upper side of the inside of the base 1, and a fixing frame 8 is fixedly installed on the upper side of the fixing plate 7. A first cylinder 16 is fixedly installed on the upper side of the inside of the fixing frame 8, and a connecting block 17 is fixedly installed on the front side of the first cylinder 16. A second cylinder 18 is fixedly installed on the lower side of the connecting block 17, and a welding gun 19 is fixedly installed on the lower side of the second cylinder 18. When the second cylinder 18 is activated, it causes the welding gun 19 to slide downwards and perform spot welding on the front side of the battery box housing. When the first cylinder 16 is activated, it causes the connecting block 17 to slide back and forth inside the fixing frame 8, thereby causing the connecting block 17 to move the welding gun 19 to the rear side of the battery box housing. When the second cylinder 18 is activated, it causes the welding gun 19 to slide downwards and perform spot welding on the rear side of the battery box housing. When the second cylinder 18 is activated, it causes the welding gun 19 to move downwards and perform spot welding on the rear side of the battery box housing. The welding gun 19 slides upward, activating the motor 10. The motor 10 drives the connecting wheel 11 to rotate on the right side of the connecting plate 9, causing the connecting wheel 12, which meshes with the connecting wheel 11, to rotate. This causes the connecting wheel 12 to rotate the movable plate 2 180°, which in turn causes the mounting plate 3 to rotate, thus flipping the battery box housing. The second cylinder 18 is then activated, causing the welding gun 19 to slide downward and perform spot welding on the front side of the battery box housing. The first cylinder 16 is then activated, causing the connecting block 17 to slide back and forth inside the fixed frame 8. This causes the connecting block 17 to move the welding gun 19 to the rear side of the battery box housing. The second cylinder 18 is then activated, causing the welding gun 19 to slide downward and perform spot welding on the rear side of the battery box housing, ensuring a good welding effect on the battery box housing.

[0035] When using the welding fixture for the battery case housing with calibration function, specifically as follows: Figure 1 , Figure 6 and Figure 7 In this process, the battery box housing is placed inside the mounting block 5. The moving rod 15 is connected to the mounting block 5 by a thread, and the moving rod 15 is connected to the connecting block 21 through a bearing. Rotating the moving rod 15 causes the moving rod 15 to be threaded on the front side of the mounting block 5. The connecting block 21 is connected to the mounting block 5 by a sliding method, and the mounting block 5 is symmetrically distributed about the center line of the mounting plate 3. This allows the connecting block 21, which is connected to the moving rod 15 through the bearing, to slide backward inside the mounting block 5. This causes the connecting block 21 to drive the protective pad 14 and the buffer pad 20 to clamp the battery box housing, making it convenient to fix battery box housings of different sizes.

[0036] Specific examples Figure 1 , Figure 3 and Figure 6In the process, the mounting rod 13 is rotated and connected to the movable plate 2 by rotation. The mounting rod 13 is also connected to the moving block 4 by thread. The mounting rod 13 rotates on the outer side of the upper end of the movable plate 2, causing the moving block 4, which is threaded to the mounting rod 13, to slide inward on the outer side of the middle of the mounting plate 3. This causes the moving block 4 to drive the mounting block 5 to slide inward inside the mounting plate 3. The front cross-sectional shape of the calibration block 6 is inclined, causing the mounting block 5 to drive the battery box housing to slide inward. This allows the mounting block 5 to drive the calibration block 6 to slide and position on the rear side of the mounting block 5 on the other side, facilitating the calibration of the battery box housing.

[0037] Specific examples Figure 2 , Figure 4 , Figure 5 and Figure 8 In the process, the second cylinder 18 is activated, causing the welding gun 19 to slide downwards and perform spot welding on the front side of the battery box housing. The first cylinder 16 is activated, causing the connecting block 17 to slide back and forth inside the fixing frame 8, thereby moving the welding gun 19 to the rear side of the battery box housing. The second cylinder 18 is activated, causing the welding gun 19 to slide downwards and perform spot welding on the rear side of the battery box housing. The second cylinder 18 is activated, causing the welding gun 19 to slide upwards. The connecting wheel 11 and the connecting plate 9 are connected by rotation, and the vertical cross-section of the connecting plate 9 is an "L" shape. The motor 10 is activated, causing the connecting wheel 11 to rotate on the right side of the connecting plate 9. The connecting wheel 11 and the connecting wheel 12 are connected by rotation. The mounting plate 3 is rotated by an interlocking mechanism, which in turn rotates the connecting wheel 12, which is connected to the connecting wheel 11. This causes the connecting wheel 12 to rotate the movable plate 2 by 180°, which in turn rotates the mounting plate 3. This causes the mounting plate 3 to flip the battery box housing. The second cylinder 18 is then activated, causing the welding gun 19 to slide downwards and perform spot welding on the front side of the battery box housing. The first cylinder 16 is then activated, causing the connecting block 17 to slide back and forth inside the fixing frame 8. This causes the connecting block 17 to move the welding gun 19 to the rear side of the battery box housing. The second cylinder 18 is then activated, causing the welding gun 19 to slide downwards and perform spot welding on the rear side of the battery box housing. This ensures a good welding effect on the battery box housing.
