Automatic Carving Device for Wheel

An automatic carving device for a wheel, comprising:

• a rack, a chassis, a lifting cylinder, brackets A, bearing blocks, linear bearings, mounting plates, guide shafts, a lifting shaft, a servo motor A, a synchronous pulley A, a connection plate, a synchronous belt, a synchronous pulley B, a pedestal, a connection shaft A, a servo motor B, a shaft sleeve A, a lower end cover, a connection shaft B, a shaft sleeve B, an oil cylinder, bearings A, end covers, a gland, bearings B, a chassis, a flange plate, pin rolls, springs, expanding petals, a connection shaft C, a protection, an expanding core, a servo motor C, a lead screw A, a linear guide rail A, a sliding rack A, a linear guide rail B, a lead screw B, a servo motor D, a sliding rack B, a carving machine, a carving knife, and a bracket B;
• wherein the chassis and the bracket B are fixed on the rack, the mounting plates are fixed on the chassis via the brackets A, the bearing blocks are fixed on the mounting plates, the lifting shaft is installed on the bearing blocks via the linear bearings, two ends of the lifting shaft are connected with the connection plate and an output shaft of the lifting cylinder respectively, the servo motor A and the pedestal are fixed on the connection plate, the shaft sleeve A is installed on the pedestal via the bearings A and the end covers, the synchronous pulley A is connected with an output shaft of the servo motor A, the synchronous pulley B is connected with the connection shaft A, and the synchronous belt is connected with the synchronous pulley A and the synchronous pulley B, respectively;
• the lower end cover, the gland and the chassis are fixed on the shaft sleeve A, the servo motor B is installed at the lower end cover, the shaft sleeve B is installed on the shaft sleeve A via the bearings B and the gland, the oil cylinder is fixed in the shaft sleeve B, an output end of the oil cylinder is connected with the connection shaft B, the servo motor B is connected with the shaft sleeve B via the connection shaft B, the expanding core is connected with the shaft sleeve B via the connection shaft C, the expanding core, the connection shaft C and the shaft sleeve B are circumferentially locked without relative rotation, the connection shaft C and the shaft sleeve B can relatively move axially, the flange plate is fixed on the chassis, eight uniformly distributed T-shaped sliding chutes are formed in an inner cavity of the flange plate and the chassis, bottom surfaces of the eight expanding pedals are respectively in one-to-one correspondence with the eight T-shaped sliding chutes, the expanding pedals can slide smoothly in the sliding chutes with high precision, the inner side wall of each expanding pedal is a slope of 15 degrees, and two ends of each of the eight springs are connected with the flange plate and the corresponding expanding pedal respectively;
• side surfaces of the expanding core comprise two sets of slopes and slopes of 15 degrees which are uniformly distributed at intervals, the number of slopes in each set is eight, two slopes have a height difference, side walls of the upper ends of the two sets of slopes join at a conical surface, when the expanding core is placed at a bottommost position, side walls of the expanding pedals contact the conical surface of the expanding core, the servo motor B drives the expanding core via the connection shaft B, the shaft sleeve B and the connection shaft C to rotate for 22.5 degrees, and the expanding pedals are matched with the slopes and can convert between the slopes and of the expanding core;
• the oil cylinder drives the connection shaft C and the expanding core to move up and down, by the slope cooperation of the expanding pedals and the slopes of the expanding core, the eight expanding pedals synchronously move centripetally and centrifugally along the eight uniformly distributed T-shaped sliding chutes formed in the inner cavity of the flange plate and the chassis, and thereby the eight expanding pedals achieves the high-precision synchronous expanding and shrinking function;
• and
• the servo motor C and the linear guide rail A are fixed on the mounting bracket, the lead screw A is connected with the sliding rack A and the servo motor C, the servo motor C can drive the sliding rack A via the lead screw A to move up and down along the linear guide rail A;
• the linear guide rail B and the servo motor D are fixed on the sliding rack A, the lead screw B is connected with the sliding rack B and the servo motor D, the carving machine is installed on the sliding rack B, the carving knife is installed on the carving machine, the servo motor D can drive the sliding rack B, the carving machine and the sliding rack B via the lead screw B to move left or right along the linear guide rail B.
