[0018] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0019] Example:

[0020] This embodiment provides a transformer installation box processing fixture, such as Figure 1 and Figure 2As shown, it includes a bottom plate 1, a support plate 2, a top plate 3, a plurality of cylinders 8, a pressing plate 6 and a limiting mechanism 9. A support plate is fixedly arranged on the upper side, the lower side and the middle of the bottom plate 1, respectively. The upper end surface of the support plate is fixed to the top plate 3. A row of placement grooves 10 are opened in the top plate corresponding to the gap between adjacent support plates. The edge of the placement groove is provided with a plurality of gaskets for protecting the mounting edge of the transformer mounting box. The placement groove 10 matches the transformer mounting box 5 and is used for placing the transformer mounting box 5. A plurality of cylinders 8 are fixedly arranged on the bottom plate corresponding to the gap between adjacent supports. The number of cylinders 8 is one more than the number of placement grooves 5. The piston rods of the cylinders 8 are arranged through the top plate 3. The cylinders 8 and the placement grooves 5 are arranged alternately, that is, a cylinder 8 is arranged on the left and right sides of each placement groove 5. A clamping block 11 is arranged at the end of the piston rod of the cylinder 8. A plurality of gourd holes 7 are arranged on the pressing plate 6 for the cylinder piston rod. The size of the gourd hole matches the size of the cylinder. When the pressing plate is fixed to the piston rod of the cylinder through the gourd hole, the pressing plate can press and fix the mounting edge of the transformer mounting box to the top plate when the cylinder piston rod contracts. In addition, the limiting mechanism is arranged on the side of the placement groove.

[0021] like Figure 3 As shown, the limiting mechanism includes a mounting block 13, a spring pin 14 and an adjusting nut 15. A groove 12 for fixing the mounting block 13 is provided at the edge of the placement slot. The spring pin 14 is movably arranged in the mounting block 13. The adjusting nut 15 is arranged at the end of the spring pin 14 to adjust the length of the spring pin extending out of the mounting block. In this embodiment, the limiting mechanism is provided with the right side and the lower side of the placement slot, so as to make the transformer mounting plate abut against the left side and the upper side of the placement slot.

[0022] When the pressing plate is fixed to the piston rod, the clamping block 11 is first passed through the large hole of the gourd hole on the pressing plate, and then the pressing plate is translated so that the small hole of the gourd hole is embedded in the clamping portion between the clamping block and the piston rod. In this embodiment, the gourd holes on the pressing plate have different diameters, and the sizes of the corresponding clamping blocks on the piston rods of the cylinders are also different, so that the setting direction and translation direction of the pressing plate can be limited to avoid collisions between the pressing plate and the processing equipment during processing due to the wrong translation direction.

[0023] In addition, in this embodiment, a hanging ring 4 is provided on the top plate, through which the fixture can be hoisted by a crane, so as to facilitate the installation of the transformer installation box processing fixture. At the same time, a mounting hole is also provided on the bottom plate, through which the transformer installation box processing fixture is fixedly set on the processing workbench.

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
