The invention relates to a brake disc processing technology, step 1: rough and fine car brake disc small end two friction surfaces; step 2: rough and fine car brake disc big end two friction surfaces; step 3: processing the brake disc big end Holes on the end face and small end face; Step 4: Dynamic balance and weight removal inspection; when turning the large end face and small end face of the brake disc, double-end turning tools are used to improve processing efficiency and ensure the stability of the braking effect. When processing the holes of the big end face and small end face of the brake disc, the fourth-axis rotary table is used to realize the end face hole processing, and the process merging is considered in the process design to reduce the process turnover bump. The dynamic balance de-weight detection adopts the tensioning fixture to improve the dynamic balance accuracy of the brake disc product, and realizes the same self-centering clamping function through the expansion force of the expansion sleeve to expand and open the expansion flap, which can not only meet the balance process requirements of the brake disc It can also reduce the manufacturing cost of the process fixture.

Fully dynamically balanced couplings, including half-couplings at the power input end, half-couplings at the power output end, input end jackets, output end jackets, intermediate sections, diaphragm sets, infrared probes, key phase magnetic strips and accessories Heavy flange; the input end sheath and the output end sheath are respectively set on the shaft hubs of the power input half coupling and the power output half coupling through the counterweight flange; the input end sheath passes through the intermediate section It is connected with the output end sheath; the diaphragm group is set between the input end sheath, the output end sheath and the intermediate section; the key phase magnetic strip is set on the power input end half coupling or the power output end half coupling method on the blue plate; the infrared probe is set on the upper end of the key phase magnetic strip; the counterweight flange is provided with a counterweight screw hole. For the unit equipped with the coupling of the present invention, the key phase magnetic strip, the infrared probe and the shaft vibration detection instrument of the unit itself can be used together to determine the unbalanced mass and phase, and only one stop is required. The screw plug of unbalanced mass is screwed into the heavy screw hole to obtain accurate dynamic balance of the unit.

The invention relates to the technical field of molds and particularly relates to a mold for a worm wheel of an automobile worm wheel supercharger. The mold comprises a fixed mold bottom plate, a stripping plate, a fixed mold plate, a fixed mold core, line assemblies, a movable mold core, a movable mold plate, a movable mold base plate, square iron, a top needle plate, a bottom needle plate and a movable mold bottom plate, wherein the line assemblies are arranged at the peripheries of the mold cores; each line assembly comprises a line push seat, a line slide seat, a line upper insert, a line lower insert, line guide blocks, a line stopping block and an inclined guide column; each line push seat is mounted on the movable mold base plate and the upper part of the line push seat is inserted into the corresponding line slide seat; each line slide seat is provided with an inclined groove; each line lower insert is embedded into the corresponding inclined groove from the front end of each line slide seat; each line upper insert is embedded into the top surface of the corresponding line lower insert from the rear end of the corresponding line lower insert; the line guide blocks are fixedly arranged on the two sides of a corresponding slide groove; the line stopping blocks are stopped and pressed at the rear ends of the corresponding line inserts; and the inclined guide columns obliquely penetrate through the movable mold base plate from the fixed mold plate. The mold is used for forming the high-precision and high-quality worm wheel, and the dynamic balance precision of the worm wheel is improved.
