[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Example 1, as Figure 1 As shown, a box welding fixture includes: a positioning plate 1 for supporting the box, the box being disposed above the positioning plate 1, and the positioning post 101 being adapted to the central positioning hole of the box.

[0022] like Figure 2 As shown, the positioning plate 1 is provided with a positioning post 101 and a drive unit 102. The drive unit 102 is connected to the positioning plate 1 and moves along the Y-axis. The drive unit 102 is connected to the positioning post 101 and is used to drive the positioning post 101 to move along the Z-axis. The positioning plate 1 is provided with a clamping device 2 for clamping the box body. The clamping device 2 passes through the box body mounting hole and comes into close contact with the box body. The clamping device 2 is connected to the positioning plate 1 and moves along the Y-axis. The clamping device 2 can rotate around the Z-axis. The positioning plate 1 has a first strip groove 107 for the drive unit 102 to move along the Y-axis. The positioning plate 1 has a second strip groove 108 for the clamping device 2 to move along the Y-axis. The drive unit 102 is located in the first strip groove 107, and the clamping device 2 is located in the second strip groove 108.

[0023] like Figure 8 As shown, specifically, the drive unit 102 is a lifting cylinder or an electric push rod, used to drive the positioning column 101 to move along the Z-axis direction. The positioning column 101 is adjusted according to the thickness of different models of boxes so that the positioning column 101 can be matched with the center positioning hole of the box to position the box and adapt to various models of boxes.

[0024] like Figure 7 As shown, the positioning plate 1 is further slidably connected to the first support plate 103, and the first support plate 103 is connected to the drive unit 102. A first sliding component 106 is provided between the positioning plate 1 and the first support plate 103. The first sliding component 106 is a slider slide rail structure. The first support plate 103 moves along the Y-axis direction on the positioning plate 1 through the first sliding component 106, driving the drive unit 102 to move along the Y-axis direction, so as to adjust the movement of the positioning column 101 in the Y-axis direction. According to the center positioning hole on different models of boxes, the appropriate position is adjusted to ensure that positioning can be achieved for different models of boxes.

[0025] like Figure 3As shown, specifically, the clamping device 2 is a lever clamping cylinder or a toggle-type quick clamp, which can be adjusted according to the thickness of the housing by replacing parts or selecting an adjustable stroke lever clamping cylinder.

[0026] like Figure 2 As shown, preferably, two clamping devices 2 are arranged opposite each other, which can improve the clamping effect of the tooling on the box, ensure that the box can be stably clamped, and facilitate subsequent welding.

[0027] like Figure 4 As shown, specifically, the clamping device 2 includes a second drive unit 201 and a pressure rod 202 for clamping the box body. The output end 211 of the second drive unit 201 is connected to the pressure rod 202. A movable disk 203 is provided between the pressure rod 202 and the second drive unit 201, which is fitted onto the output end 211 and rotates around the output end 211. The output end 211 is slidably connected to the movable disk 203 and moves along the Z-axis. The second drive unit 201 is the power source of the lever clamping cylinder, and the output end 211 is the piston rod. By rotating the movable disk 203, the position of the pressure rod 202 is adjusted to clamp different positions of the box body. According to different types of box bodies, the movable disk 203 is adjusted to drive the pressure rod 202 to rotate to a suitable position, providing a more stable clamping force.

[0028] like Figure 4 As shown, a locking part 3 is further provided between the movable disk 203 and the drive part 201 to limit the position of the movable disk 203. When the movable disk 203 is rotated until the pressure rod 202 is in a suitable pressing position, the movable disk 203 is locked by the locking part 3 to prevent the rotation of the movable disk 203 from affecting the pressure rod 202 during the welding process, thereby reducing the welding quality.

[0029] like Figure 4 As shown, specifically, the locking part 3 includes a first through hole 301, a second through hole 302, and a first pin 303. The first through hole 301 is provided on the extension 231 of the movable plate 203. The driving part 201 is provided with a plurality of second through holes 302. The first pin 303 passes through the first through hole 301 and cooperates with the second through hole 302 to limit the position of the movable plate 203. When the movable plate 203 is rotated to a suitable position by the housing, the first through hole 301 and the second through hole 302 are aligned and limited by the first pin 303, so that the first through hole 301 no longer moves relative to the second through hole 302, thereby limiting the position of the movable plate 203.

[0030] like Figure 3As shown, further, both sides of the second drive unit 201 are provided with limiting plates 204 for limiting the position of the second drive unit 201. The second drive unit 201 is connected to the second support plate 205, and a second sliding component 206 is provided between the second support plate 205 and the positioning plate 1. The second sliding component 206 has the same structure as the first sliding component 106. The limiting plates 204 are provided on the second support plate 205. When the second drive unit 201 slides relative to the positioning plate 1 in the second strip groove 108 through the second sliding component 206, the limiting plates 204 can protect the second drive unit 201 from contacting the edge of the second strip groove 108, thereby damaging the second drive unit 201, and can also prevent the second drive unit 201 from sliding off.

[0031] like Figure 3 As shown, a third sliding component 207 is further provided between the output end 211 and the movable disk 203.

[0032] like Figure 5 As shown, the third sliding component 207 includes a guide rail 271 and a connecting block 272. The guide rail 271 is disposed on the movable disk 203 and slides in cooperation with the connecting block 272. The output end 211 is connected to the connecting rod 208, the connecting rod 208 is connected to the connecting block 272, and the pressure rod 202 is fitted on the connecting rod 208 and located between the output end 211 and the connecting block 272. The pressure rod 202 can rotate around the connecting rod 208.

[0033] like Figure 5 As shown, after the housing is positioned by the positioning post 101 and the fixing plate 104, the clamping device 2 has not yet clamped the housing. The output end 211 has not moved upward along the Z-axis, causing the connecting rod 208 and the connecting block 272 to be located at one end of the guide rail 271 near the drive part 201. One end of the pressure rod 202 is fitted onto the connecting rod 208, and it is located at one end of the guide rail 271 near the drive part 201 along with the connecting rod 208. The other end of the pressure rod 202 is lifted due to the characteristics of the cylinder and does not clamp the housing.

[0034] like Figure 6 As shown, after the housing is positioned by the positioning pin 101 and the fixing plate 104, and the housing is pressed, the output end 211 moves upward along the Z-axis to the end of the guide rail 271 away from the drive unit 201, causing the connecting rod 208 and the connecting block 272 to be located at the end of the guide rail 271 away from the drive unit 201. One end of the pressure rod 202 is located at the end of the guide rail 271 away from the drive unit 201 along with the connecting rod 208, and the other end of the pressure rod 202 presses the housing due to the characteristics of the cylinder.

[0035] Example 2: In order to further improve the positioning effect of the box, this example adds a fixing plate 104 to the basis of Example 1, which forms a three-point positioning with the positioning post 101.

[0036] like Figure 1 As shown, a fixing plate 104 for limiting the position of the box is provided on any two adjacent corners of the positioning plate 1. The fixing plate 104 is provided with multiple limiting holes 141, which are connected to the fixing posts 142. The end face of the fixing post 142 in the Z-axis direction is higher than the end face of the fixing plate 104, and the cylindrical surface of the fixing post 142 can contact the box. Through the contact between the fixing post 142 and the box, during the positioning process, the fixing post 142 on the two fixing plates 104 and the positioning post 101 form a three-point positioning, which further stabilizes the positioning and improves the stability of the tooling.

[0037] like Figure 2 As shown, furthermore, the positioning plate 1 is provided with multiple pads 105 that contact the box body, such as... Figure 4 As shown, the side of the pressure rod 202 opposite to the housing is provided with a pressure block 221 that comes into close contact with the housing. The pressure block 221 contacts the housing through the pad 105 and the pressure plate 105, preventing the housing from directly contacting the positioning plate 1 and the pressure rod 202, thus protecting the housing. When clamping the housing, the pressure rod 202 approaches the housing, and the pressure block 221 contacts the housing. The pressure rod 202 continuously applies pressure to the pressure block 221 through the output end 211 until the pressure block 221 comes into close contact with the housing, pressing the housing tightly so that it will not be displaced due to external force during the subsequent welding process.

[0038] like Figure 2 As shown, a locking part 2 4 is further provided between the first support plate 103 and the positioning plate 1 to limit the position of the first support plate 103. The locking part 2 4 limits the first support plate 103 after it has been adjusted to a certain position, thereby improving the stability of the tooling.

[0039] like Figure 7 As shown, specifically, the locking part 2 4 includes a third through hole 401, a fourth through hole 402, and a second pin 403. The third through hole 401 on the first support plate 103 corresponds to the fourth through hole 402 on the positioning plate 1. The second pin 403 passes through the third through hole 401 and engages with the fourth through hole 402 to limit the first support plate 103, thereby limiting the positioning post 101. After the first support plate 103 is moved to a suitable position by the first sliding assembly 106, the third through hole 401 and the fourth through hole 402 are aligned. The second pin 403 limits the movement of the third through hole 401 relative to the fourth through hole 402, thereby limiting the first support plate 103 and preventing the first support plate 103 from shifting due to external force during the welding process.

[0040] Working principle: Place the box on the positioning plate 1, and adjust the position of the positioning column 101 and the clamping device 2 in the Y-axis direction according to the position of its center positioning hole and mounting hole. Then, adjust the position of the positioning column 101 in the Z-axis direction according to the thickness of the box to position the box. At this time, select the appropriate limiting hole 141 on the fixing plate 104 according to the box, connect the fixing column 142 to the limiting hole 141 to position the box and form a three-point positioning with the positioning column 101. Adjust the clamping device 2 to be able to clamp the box. Then, select the appropriate clamping position according to the box, rotate the clamping device 2 to the appropriate clamping position to clamp the box.
