Jig for low-voltage tuning filter cabinet and using method thereof

Abstract

The invention relates to the technical field of hemming jigs, in particular to a jig for a low-voltage tuning filter cabinet and a using method thereof. The jig comprises a jig base, wherein a motor driving box is arranged on one side of the jig base, and a stepping motor is arranged in the motor driving box; a bevel pinion is arranged at the output end of the stepping motor, and a winding roller is connected to the bevel pinion; a supporting table and a protection plate are arranged on the jig base, a winding roller bin is formed between the supporting table and the protection plate, and the winding roller is rotationally arranged in the winding roller bin; and a fastening plate is fixedly arranged on the winding roller, and a fastener is arranged below the fastening plate. A material penetrates through the position between the coiled material protection plate and the supporting table, and a fastening handle on a mounting hole is adjusted, so that the fastening plate and the upper side face of the winding roller compress the material at the same time. The machined material can be wound into an L-shaped structure or a U-shaped structure according to needs in the rotating process of the winding roller, the using flexibility and convenience are improved, and the material winding efficiency and precision are improved.

Description

technical field [0001] The invention relates to a jig and its use method, in particular to a jig for a low-voltage tuning filter cabinet and its use method, and belongs to the technical field of crimping jigs. Background technique [0002] The filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency points of a specific frequency in the power line or frequencies other than this frequency point, obtain a power signal of a specific frequency, or eliminate a specific frequency. frequency after the mains signal. [0003] During the processing of filter cabinets, materials need to be crimped. The traditional method is to use tools to manually crimp, which is inefficient and cannot guarantee the accuracy of processing, thus affecting work efficiency.

Problems solved by technology

[0003] During the processing of the filter cabinet, the material needs to be crimped. The traditional method is to use tools to manually crimp the edge. The efficiency is low and the processing accuracy cannot be guaranteed, thus affecting the work efficiency.

[0004] Chinese Invention Patent Publication No. CN 203565605 U discloses "a new type of crimping fixture", which includes a fixed base and a connecting rod. The end of the connecting rod is connected to a rotating rod, and the rotating rod is attached to the fixed base. , the connecting rod is also provided with an extruding rod, the extruding rod can slide left and right on the connecting rod, the rotating rod is provided with a flange, the flange is semicircular, and the extruding rod A concave groove is provided on the pressure rod, the concave groove is semicircular, the radius of the semicircular flange is the same as that of the semicircular concave groove, and a starting device is connected to one side of the rotating rod , the structure is too simple, and it is not suitable for large-area sheet curling. Moreover, it needs to be supported by hands while curling. The efficiency is low and the accuracy of curling cannot be guaranteed.
