[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1 and Figure 2 As shown, a welding clamping device for automobile parts production includes an operating table 1, a clamping mechanism 5 is slidably connected to the front side of the upper end of the operating table 1, a welding mechanism 2 is fixedly connected to the front side of the upper end of the operating table 1, a transmission mechanism 7 is fixedly connected to the middle part of the upper end of the operating table 1, a transfer mechanism 3 is arranged on the right side of the transmission mechanism 7, a feeding mechanism 8 is slidably connected to the middle part of the upper end of the operating table 1 located behind the clamping mechanism 5, the feeding mechanism 8 includes a rack 3 82, a blowing mechanism 4 is arranged on the left part of the feeding mechanism 8, and an auxiliary mechanism 6 is fixedly connected to the right side of the upper end of the operating table 1.

[0023] When producing the battery pack of an electric vehicle accessory, the frame of the battery pack and the required water cooling plate need to be welded first, and then the next step of assembly and welding of the battery pack can be carried out.

[0024] When welding the outer frame of the battery pack and the water-cooling plate, first place the frame to be welded on the upper part of the clamping mechanism 5, and at the same time place a container for storing the water-cooling plate on the upper end of the operating table 1, then cooperate with the welding mechanism 2, the unloading mechanism 8 and the blowing mechanism 4, and in the process of pushing downward in preparation for welding, the blowing mechanism 4 cooperates with the clamping mechanism 5 to clamp the outer frame of the battery pack, and at the same time, the transmission mechanism 7 cooperates with the transfer mechanism 3 to continuously remove the water-cooling plate and place it in the outer frame of the battery pack, and cooperate with the welding mechanism 2 to weld. After the welding of one water-cooling plate and the outer frame is completed, in the process of the transfer mechanism 3 taking a new water-cooling plate, the transmission mechanism 7 cooperates to make the clamping mechanism 5 and the outer frame as a whole move a distance to the right, and then continue to weld the new water-cooling plate and the outer frame.

[0025] After the water-cooling plate is evenly welded inside the outer frame, the welding mechanism 2 is reset as a whole. During the resetting process, the clamping mechanism 5 releases the lock on the outer frame by cooperating with the unloading mechanism 8 and the blowing mechanism 4. At the same time, the unloading mechanism 8 pushes the welded battery pack frame forward as a whole for unloading. After unloading, the clamping mechanism 5 is reset as a whole through the cooperation of the auxiliary mechanism 6 to carry out the next welding between the outer frame and the water-cooling plate.

[0026] During the operation of this embodiment, the blowing mechanism 4 and the clamping mechanism 5 cooperate to continuously clamp the outer frame of the battery pack, while avoiding movement or deformation of the frame during welding. At the same time, the transfer mechanism 3 can efficiently remove the water-cooled plate and place it in the outer frame of the battery pack to prepare for welding. Similarly, the transfer mechanism 3 and the transmission mechanism 7 cooperate to enable the transfer and welding process of the water-cooled plate to be carried out continuously, thereby improving the smoothness of the production line. At the same time, the unloading mechanism 8 cooperates to push the outer frame to automatically unload during the resetting process of the welding mechanism 2, thereby further improving the welding efficiency.

[0027] Embodiment 2: Based on Embodiment 1, this embodiment can drive the outer frame to move a certain distance in the process of preparing to remove the water-cooling plate for welding, so as to achieve the effect of indirect equidistant welding.

[0028] See also Figure 3 A through hole 11 is opened at the middle and rear side of the upper end of the operating platform 1, a through hole 2 12 is opened at the rear side of the upper end of the operating platform 1, a switch button 13 is fixedly connected to the middle and upper part of the rear side of the upper end of the operating platform 1, a rectangular guide rail 14 is fixedly connected to the middle and rear side of the upper end of the operating platform 1, a fixed seat 15 is fixedly connected to the front side of the upper end of the operating platform 1, and a guide rod 151 is symmetrically fixedly connected to the upper end of the fixed seat 15.

[0029] The switch button 13 mentioned above is electrically connected to the external power supply, and welding can be triggered when the switch button 13 is squeezed. Through the cooperation of the external power supply and the control system, welding can be achieved when the switch button 13 is squeezed.

[0030] Furthermore, during the welding process of the battery pack outer frame and the water cooling plate, the fixing seat 15 and the two guide rods 151 are provided to avoid the displacement of the clamping mechanism 5 during the movement of the clamping outer frame, and the rectangular guide rail 14 cooperates to limit the unloading mechanism 8.

[0031] See also Figure 4 The clamping mechanism 5 includes a fixing plate 3 51, a rectangular groove 512 is symmetrically provided at the lower end of the fixing plate 3 51, the inner surfaces of the two rectangular grooves 512 are slidably connected to the outer surface of the matching guide rod 151, and a limiting groove 511 is symmetrically provided at the upper end of the fixing plate 3 51. The inner surfaces of the two limiting grooves 511 on the same side are fixedly connected with a spring 2 54 on one side close to each other, and the two springs 2 54 on the same side are fixedly connected with a clamping block 2 53 on one end away from each other. The four clamping blocks 2 53 are respectively slidably connected to the inner surfaces of the matching limiting grooves 511, and a rack 2 52 is fixedly connected to the rear end of the fixing plate 3 51.

[0032] Specifically, before preparing for welding, the outer frame is first placed on the upper end of the fixed plate three 51, and the four clamping blocks two 53 cooperate with the springs two 54 to simply clamp the outer frame. During the clamping process, the four clamping blocks two 53 slide along the inner surface of the limiting groove 511 to the side away from the spring two 54. During the sliding process, the four springs two 54 are stretched at the same time, and then the four springs two 54 pull the matching clamping blocks two 53, so that the four clamping blocks two 53 clamp the outer frame.

[0033] See also Figure 6 The welding mechanism 2 includes a hydraulic cylinder 21 fixedly connected to the upper end of the operating table 1, a horizontal plate 22 is fixedly connected to the output end of the hydraulic cylinder 21, a welding head 23 is fixedly connected to the right end of the horizontal plate 22, an L-shaped rod 24 is fixedly connected to the rear side of the right end of the horizontal plate 22, and a rack 25 is fixedly connected to the rear end of the horizontal part of the L-shaped rod 24.

[0034] After the four clamping blocks 2 53 cooperate with the spring 2 54 to clamp the outer frame, the hydraulic cylinder 1 21 is activated, and then the output end of the hydraulic cylinder 1 21 pushes the cross plate 22 downward. During the downward movement of the cross plate 22, the welding head 23 and the L-shaped rod 24 are driven to move downward at the same time, and then the L-shaped rod 24 drives the rack 1 25 to move downward.

[0035] Similarly, the welding head 23 is connected to the external power supply and the control system, and when the switch button 13 is squeezed, the welding head 23 can be triggered to operate for welding; At the same time, the external control system controls the welding route of the welding head 23 to be always fixed. Since it is set in advance, the welding route of the welding head 23 is the part where the water cooling plate is in close contact with the bottom of the outer frame.

[0036] See also Figure 5The blowing mechanism 4 includes a fixing plate 2 43 fixedly connected to the left end of the rack 3 82, a fixing plate 1 41 is fixedly connected to the middle of the upper end of the operating table 1, and a telescopic tube 42 is fixedly connected to one end of the fixing plate 1 41 and the fixing plate 2 43 close to each other, and an airbag 1 44 is fixedly connected to the inner surface of the telescopic tube 42, and a hose 45 is fixedly connected to the front end of the airbag 1 44, and four airbags 2 46 are fixedly connected to the output end of the hose 45, and the four airbags 2 46 are respectively fixedly connected to the matching clamp block 2 53.

[0037] Furthermore, during the process of the rack 1 25 descending, the rack 3 82 is moved backwards by cooperation, and during the process of the rack 3 82 moving backwards, the fixing plate 2 43 is driven to move backwards, and then the rear end of the telescopic tube 42 is driven to move backwards, and at this time, the telescopic tube 42 is stretched, and then the airbag 1 44 inside the telescopic tube 42 is stretched, and at this time, the air pressure inside the airbag 1 44 becomes smaller, and the hose 45 cooperates with the four airbags 2 46, and during the process of the airbag 1 44 being stretched and the internal air pressure becoming smaller, the internal air pressure of the four airbags 2 46 is reduced, and then the four airbags 2 46 are contracted; During the contraction of the four airbags 2 46 , the four clamping blocks 2 53 are pulled to move toward the side close to the spring 2 54 , thereby continuously clamping the outer frame between the four clamping blocks 2 53 .

[0038] When the output end of the hydraulic cylinder 21 stops pushing the cross plate 22 downward, the telescopic tube 42 and the airbag 1 44 are no longer stretched, and then the airbag 1 44 cooperates with the hose 45 and the four airbags 2 46 to maintain the air pressure state before the cross plate 22 stops moving, and then the four airbags 2 46 cooperate with the four clamping blocks 2 53 to clamp the outer frame.

[0039] See also Fig.10 and Fig.11 The transmission mechanism 7 includes a vertical plate 2 71 fixedly connected to the rear side of the upper end of the operating table 1, a motor 72 is fixedly connected to the middle of the left end of the vertical plate 2 71, an intermittent gear 73 is fixedly connected to the output end of the motor 72, and a gear 1 74 is meshed on the outer surface of the intermittent gear 73, the right end of the vertical plate 2 71 is rotatably connected to two gears 4 79, the outer surfaces of the two gears 4 79 are meshed with each other, and a gear 3 78 is provided on the left ends of the two gears 4 79, a roller 2 75 is rotatably connected to the lower side of the left end of the vertical plate 2 71, the middle part of the outer surface of the roller 2 75 is fixedly connected to the inner surface of the gear 3 78, the left end of the roller 2 75 is transmission-connected to the roller 3 76, and the lower part of the outer surface of the roller 3 76 is transmission-connected to the roller 4 77.

[0040] When the welding head 23 is pushed downward to a suitable welding position, the motor 72 is stimulated so that the output end of the motor 72 drives the intermittent gear 73 to rotate continuously. At the same time, since the gear teeth on the outer surface of the intermittent gear 73 are symmetrically arranged up and down, when the gear teeth are driven by the intermittent gear 73 to rotate and mesh with the outer surface of gear 1 74, the gear teeth on one side mesh with gear 1 74 to drive gear 1 74 to rotate 180 degrees, and then no longer mesh with gear 1 74. At this time, gear 1 74 no longer rotates, and when the gear teeth on the other side mesh with gear 1 74 again, they continue to drive gear 1 74 to rotate 180 degrees. In this way, the output end of the motor 72 drives the intermittent gear 73 to rotate continuously, and then cooperates with gear 1 74 to realize the intermittent rotation of gear 1 74 by 180 degrees.

[0041] Furthermore, while the gear 1 74 is rotating, the two gears 4 79 cooperate with each other to make the two gears 4 79 rotate intermittently, and then the two gears 4 79 cooperate to make the gear 3 78 rotate, which in turn makes the roller 2 75 rotate.

[0042] The left end of the outer surface of the second transfer roller 75 is connected to the transmission by meshing with a bevel gear in the prior art, so that the third transfer roller 76 is driven to rotate when the second transfer roller 75 is driven to rotate.

[0043] At the same time, the lower part of the outer surface of the above-mentioned transfer roller three 76 is connected to the outer surface of the rotating roller four 77 through a transmission belt in the prior art, so that the rotating roller four 77 can be driven to rotate half a circle every time the rotating roller three 76 rotates half a circle.

[0044] When the roller 2 75 is driven to rotate by the gear 3 78 , the roller 4 77 is rotated through the cooperation of the roller 3 76 .

[0045] See also Fig.11 The right end of gear one 74 is fixedly connected to the left end of gear four 79 located on the front side. The right ends of the two gear fours 79 have a number of levers 791 in a circular array. The outer surfaces of the number of levers 791 can be tightly attached to the outer surface of gear three 78. The outer surface of roller four 77 is fixedly connected to a one-way shaft 771. The outer surface of the one-way shaft 771 is fixedly connected to gear two 772. The outer surface of gear two 772 is meshed with rack two 52. The right part of the outer surface of roller two 75 is fixedly connected to a shift block 751. The shift block 751 can be tightly attached to the lower end of the switch button 13.

[0046] The above-mentioned roller four 77 is a conventional design in the prior art, which can enable the roller four 77 to drive the gear two 772 to rotate in one direction, and at the same time, the gear two 772 will not drive the roller four 77 to rotate during the reverse rotation.

[0047] When gear one 74 is driven to rotate half a circle, gear one 74 will drive gear four 79 fixedly connected thereto to rotate half a circle at the same time. At this time, a number of levers 791 at the right end of gear four 79 on the rear side cooperate with the outer surface of gear three 78. When gear four 79 on the rear side rotates half a circle, a number of levers 791 will shift gear three 78 to rotate gear three 78 180 degrees clockwise, thereby driving roller two 75 to rotate 180 degrees clockwise. At this time, roller two 75 will drive lever block 751 to rotate in the same direction. After lever block 751 rotates 180 degrees, lever block 751 stops rotating with gear one 74. At this time, gear three 78 and roller two 75 stop rotating at the same time. At this time, a number of levers 791 at the right end of gear four 79 on the front side just begin to be in close contact with the outer surface of gear three 78. At the same time, after the shift block 751 is driven by the shift block 751 to rotate 180 degrees clockwise, it is tightly attached to the lower end of the switch button 13, and then the welding head 23 can be triggered by the switch button 13 to start welding.

[0048] Furthermore, when the gear 1 74 continues to rotate 180 degrees, the gear 4 79 located at the front side will drive the gear 3 78 to rotate 180 degrees counterclockwise through a plurality of levers 791, and then the gear 1 74 stops rotating. At this time, the gear 3 78, the roller 2 75 and the shift block 751 rotate 180 degrees counterclockwise at the same time, and the roller 4 77 is rotated by the cooperation of the roller 3 76. At the same time, the one-way shaft 771 cooperates with the roller 4 77 and the gear 2 772. At this time, the roller 3 76 drives the roller 4 77 to rotate, which will cause the gear 2 772 to rotate, and then the rack 2 52 drives the fixed plate 3 51 to move a certain distance to the right. At the same time, through the cooperation setting of the one-way rotating shaft 771, when the rotating roller 2 75 rotates 180 degrees clockwise, the rotating roller 4 77 will not drive the gear 2 772 to rotate.

[0049] See also Figure 8 and Fig. 9 The transfer mechanism 3 includes a roller 32 that is transmission-connected to the right part of the outer surface of the roller 2 75, a vertical plate 31 is fixedly connected to the middle part of the outer surface of the roller 32, a left end of the roller 32 is fixedly connected to the limiting plate 33, a guide rod 311 is fixedly connected to the lower side of the left end of the vertical plate 31, a guide groove 312 is opened at the upper part of the left end of the vertical plate 31, a slider 34 is slidably connected to the inner surface of the guide groove 312, the middle part of the outer surface of the slider 34 is rotatably connected to the left end of the limiting plate 33, a round roller 35 is fixedly connected to the lower end of the slider 34, a rectangular block 36 is slidably connected to the middle part of the outer surface of the round roller 35, the right end of the rectangular block 36 is slidably connected to the outer surface of the guide rod 311, the lower end of the round roller 35 is fixedly connected to the limiting cover 351, the inner surface of the limiting cover 351 is symmetrically slidably connected with a clamping block 37, and the two clamping blocks 37 are fixedly connected to a spring 371 on one side close to each other.

[0050] Specifically, at this time, two clamping blocks 37 cooperate with a plurality of springs 371 to clamp a middle portion of the upper end of a water-cooling plate, and cooperate with the limiting cover 351 to clamp the water-cooling plate.

[0051] Furthermore, when the roller 2 75 is driven to rotate 180 degrees clockwise, the roller 2 75 then drives the roller 1 32 to rotate 180 degrees clockwise through the transmission belt in the prior art, and then the roller 1 32 will drive the limit plate 33 to rotate 180 degrees in the same direction. At this time, the guide groove 312 cooperates with the slider 34, and the slider 34 is driven to slide along the inner surface of the guide groove 312 during the process of the limit plate 33 rotating 180 degrees. At the same time, the slider 34 drives the upper end of the round roller 35 to rotate during the sliding process, and then through the cooperation of the rectangular block 36, the guide rod 311 and the round roller 35, the round roller 35 cooperates with the two clamping blocks 1 37 to clamp the water-cooled plate so that it can move up and down and move forward at the same time, thereby realizing the movement of the water-cooled plate to the inside of the outer frame for welding. After the roller 1 32 is driven to rotate 180 degrees clockwise, the roller 1 32 no longer rotates. At this time, the welding head 23 is stimulated by the cooperation of the dial block 751 and the switch button 13, and then welding begins.

[0052] After the welding of a water-cooled plate is completed, the rotating roller 32 is driven to reverse 180 degrees, and then the round roller 35 cooperates with the slider 34 and the rectangular block 36 to drive the two clamping blocks 37 to move up and down and move backward to clamp the next water-cooled plate. In the process of preparing to clamp the next water-cooled plate, the gear 2 772 and the rack 2 52 cooperate to make the rack 2 52 drive the fixed plate 3 51 and the outer frame to move a distance to the right.

[0053] During the operation of this embodiment, through the cooperation between the airbag 2 46 and the clamp block 2 53, the automatic clamping of the outer frame is achieved in the process of preparing for welding, and through the cooperation between the intermittent gear 73 and the gear 1 74 and the gear 4 79 and the gear 3 78, not only can the water-cooled plate be removed and accurately transferred to the inside of the outer frame when the roller 2 75 rotates clockwise, and the welding is triggered at the same time, thereby ensuring the accuracy of the welding position, but also when the roller 2 75 rotates counterclockwise, the one-way rotating shaft 771 cooperates with the gear 2 772 to make the rack 2 52 drive the outer frame to move a certain distance to the right, thereby achieving indirect equidistant welding of the water-cooled plate. Automated welding reduces the direct contact between workers and the welding area, thereby reducing labor intensity.

[0054] Embodiment 3: Based on Embodiment 1 and Embodiment 2, this embodiment is to achieve the effect of driving the triangular push block 83 to push the material forward during the resetting process of the welding head 23.

[0055] See also Figure 7The unloading mechanism 8 includes a gear 5 81 meshing with the rear side of the rack 1 25, a rack 3 82 meshing with the outer surface of the gear 5 81, a triangular push block 83 fixedly connected to the front right end of the rack 3 82, and the triangular push block 83 is slidably connected to the outer surface of the rectangular guide rail 14.

[0056] Furthermore, in the process of preparing for welding, the welding head 23 is driven downward by the cross plate 22, and at the same time, the rack 25 is driven downward. At this time, the rack 25 is meshed with the surface of the gear 5 81, so that the gear 5 81 rotates, and then the rack 3 82 moves backward. During the descent of the rack 25, it can be tightly attached to the inner surface of the through hole 11 to avoid position displacement during the descent of the rack 25. At the same time, the rack 3 82 can be tightly attached to the inner surface of the through hole 2 12 during the backward movement.

[0057] Furthermore, when rack three 82 is driven to move backward, rack three 82 also drives triangular push block 83 to move backward. At this time, airbag one 44 cooperates with four airbags two 46 to make four clamping blocks two 53 clamp the outer frame. At the same time, the front end of triangular push block 83 has been separated from the lower end of the outer frame and the upper end of fixed plate three 51.

[0058] Furthermore, when the water-cooling plates are welded equidistantly inside the outer frame, the hydraulic cylinder 21 is activated, so that the output end of the hydraulic cylinder 21 drives the horizontal plate 22 to move upward, and then drives the welding head 23 to reset. During the resetting process of the welding head 23, the rack 25 is driven to move upward, and then the gear 5 81 is reversed, and then the rack 3 82 and the triangular push block 83 move forward; When the rack gear 3 82 moves forward, the rear end of the telescopic tube 42 and the fixing plate 2 43 are driven to move forward at the same time. At this time, the airbag 1 44 inside the telescopic tube 42 is squeezed, and then the four airbags 2 46 cooperate with the hose 45. When the airbag 1 44 is squeezed, the four airbags 2 46 are inflated, and then the clamp block 2 53 is pushed toward the end away from the spring 2 54, so that the locking of the four clamp blocks 2 53 on the external frame can be released; Then the rack three 82 drives the triangular push block 83 to continue to move forward. During the forward movement of the triangular push block 83, the front end of the triangular push block 83 is inserted between the outer frame and the fixed plate three 51, and then the triangular push block 83 continues to move forward, and the outer frame can be pushed out for unloading.

[0059] See also Fig.12 The auxiliary mechanism 6 includes a hydraulic cylinder 61 fixedly connected to the upper right side of the operating platform 1, and a push plate 62 is fixedly connected to the output end of the hydraulic cylinder 61.

[0060] After the triangular push block 83 pushes the outer frame out of the blanking, the right end of the fixed plate three 51 is in close contact with the left end of the push plate 62, and then the hydraulic cylinder two 61 is stimulated, and its output end pushes the push plate 62 to the left, and then the push plate 62 pushes the fixed plate three 51 to the left, so that the fixed plate three 51 slides to the left along the outer surface of the guide rod 151. When the fixed plate three 51 is reset, the output end of the hydraulic cylinder two 61 drives the push plate 62 to reset, and then the outer frame can be placed on the upper end of the fixed plate three 51 again for the next welding.

[0061] Therefore, this solution realizes the automatic lifting and movement of the welding head 23 and the push plate 62 through the precise control of the hydraulic cylinder 1 21 and the hydraulic cylinder 2 61, thereby reducing manual intervention and improving the degree of automation of the welding process. The cooperation of mechanical transmission mechanisms such as the gear 5 81, the rack 3 82 and the triangular push block 83 enables the clamping, unlocking and unloading processes of the outer frame to be completed automatically. At the same time, it can also drive the triangular push block 83 to push the unloading forward during the resetting process of the welding head 23, further improving the overall work efficiency.

[0062] It should be particularly noted that the specific installation method, circuit connection method and control method of the hydraulic cylinder 1 21, hydraulic cylinder 2 61 and motor 72 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
