For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0027] See also Figure 1-3 A tool for welding MOSFET devices, comprising a tooling table 1, wherein a built-in cavity 2 is provided inside the tooling table 1, and two symmetrically distributed through holes 3 are provided at the upper end of the tooling table 1, wherein the through holes 3 are communicated with the built-in cavity 2, and a transmission shaft 4 is installed on the inner wall of the side of the tooling table 1, and a clamp 5 is rotatably connected to the outer end of the transmission shaft 4, and a positioning component 6 corresponding to the clamp 5 is installed at the inner bottom end of the tooling table 1, and a device body 7 is provided between the inner walls of the two clamps 5, and a control switch 8 for controlling the driving of the positioning component 6 is installed at the side end of the tooling table 1, and an adjustment component 9 is also provided at the bottom of the tooling table 1.

[0028] During use of this solution, in order to avoid the phenomenon that the welding position of the existing MOSFET device is inaccurate or the position of the welded MOSFET device is offset due to the limited space when holding the MOSFET device during welding, in this embodiment, when the MOSFET device is welding, the internal positioning component 6 is driven to move up and down by driving the control switch 8, thereby driving the clamps 5 on both sides to adjust the left and right position spacing. After adjusting to a suitable position, the personnel will place the MOSFET device between the two clamps 5, and then continue to drive the positioning component 6 until the two clamps 5 clamp the MOSFET device, so that the personnel can conveniently weld the device body 7 on the horizontal plane. When the personnel need to weld the MOSFET device at an inclined angle, the operator can rotate the overall tooling table 1 on the surface of the adjustment component 9, so that the tooling table 1 can be freely rotated at an inclined angle on the horizontal plane and obtain a certain position limit, thereby facilitating the operator to weld the MOSFET device at multiple angles.

[0029] See also Figure 1-3 The positioning assembly 6 includes a movable plate 61 provided on the side wall of the workbench 1, and the side end of the movable plate 61 is sequentially provided with a guide hole 1 63, a guide hole 2 64 and a placement hole 62 from top to bottom. The movable plate 61 is rotatably connected to the inner wall of the built-in cavity 2 by installing a transmission shaft 1 in the placement hole 62. One side end of the clamp 5 is fixedly connected to a limit rod 2 51, and the limit rod 2 51 is located between the inner walls of the guide hole 1 63. A trapezoidal lifting platform 65 is also provided between the inner walls of the workbench 1, and two clamps 5 are respectively located above the trapezoidal lifting platform 65. One side end of the trapezoidal lifting platform 65 is fixedly connected to two symmetrically distributed limit rods 1 66, and the limit rods 1 66 are respectively located between the inner walls of the guide hole 2 64. An electric push rod 67 is installed between the trapezoidal lifting platform 65 and the bottom of the workbench 1, and the electric push rod 67 is electrically connected to the control switch 8.

[0030] During use of the present solution, the two clamps 5 are respectively located in the through holes 3 on the left and right sides, and are rotatably connected with the transmission shaft 2 4, so that the clamps 5 can freely open and close in the through holes 3. In the present embodiment, the trapezoidal lifting platform 65 is set inside the built-in cavity 2, and the trapezoidal lifting platform 65 is lifted and lowered by the electric push rod 67, and the lower part of the clamps 5 is respectively located above the trapezoidal sides on the left and right sides of the trapezoidal lifting platform 65. When the trapezoidal lifting platform 65 moves upward, the bottom of the clamps 5 is simultaneously resisted, and because the movable plate 61 is rotatably connected to the inner wall of the tooling table 1 through the transmission shaft 1 installed inside the placement hole 62, and the middle end of the movable plate 61 is slidably connected with the trapezoidal lifting platform 65, the movable plate The upper end of 61 is slidably connected with the limit rod 2 51, so that when the trapezoidal lifting platform 65 is moving upward, its movable plate 61 is guided by the limit rod 1 66, and the movable plates 61 on both sides rotate and deviate inward around the transmission axis of the mounting hole 62. At the same time, the lower part of the clamp 5 is resisted by the rising of the trapezoidal lifting platform 65 and retracts inward at its inclination angle, thereby clamping and positioning the MOSFET devices placed on the inner sides of the two clamps 5 for subsequent welding work. At the same time, after the welding work is completed, the personnel drive the control switch 8 to prompt the electric push rod 67 to drive the trapezoidal lifting platform 65 downward, causing the two clamps 5 to open and close to both sides, and no longer clamping and positioning the MOSFET devices.

[0031] See also Figure 1-3 A second through hole 10 is opened at the center of the upper end of the tooling table 1 , a support plate 11 is provided between the inner walls of the second through hole 10 , and the lower end of the support plate 11 is fixedly connected to the surface of the trapezoidal lifting platform 65 .

[0032] During use of this solution, when the trapezoidal lifting platform 65 moves upward, it simultaneously drives the support plate 11 connected above to move toward the bottom of the MOSFET device, thereby contacting the bottom of the MOSFET device, providing it with a certain bottom supporting force, ensuring stability during clamping, and facilitating subsequent welding work by personnel.

[0033] See also Figure 1-2 The adjustment component 9 includes a connecting block 91 fixedly connected to the bottom of the workbench 1, and the side ends of the connecting block 91 are installed with a damping shaft 92. A base 93 is also provided on the lower side of the connecting block 91, and an arc groove 94 is opened on the top of the base 93. The damping shaft 92 is rotatably connected to the inner wall of the base 93.

[0034] During use of the present solution, in order to enable the MOSFET device to be adjusted at multiple angles during welding work, thereby facilitating welding by personnel, in the present embodiment, a connecting block 91 is provided at the bottom of the workbench 1, and under the arc groove 94 provided therein, the workbench 1 can be freely rotated at an inclination angle through the damping shaft 92. At the same time, under the action of the damping shaft 92, the workbench 1 can also be stopped at any angle, thereby facilitating welding of the MOSFET device by personnel.

[0035] See also Figure 1-3 The surfaces of the clamp 5 and the support plate 11 are both sleeved with rubber pads.

[0036] During use of the present invention, by adding rubber pads to the surfaces of the clamps 5 and the support plate 11, the friction between the two clamps 5 when clamping the MOSFET device and the support plate 11 when supporting its bottom can be increased, thereby making the clamping more stable and facilitating subsequent welding work.

[0037] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
