Abstract

An automatic carving device for a wheel, including a rack, a chassis, a lifting cylinder, brackets, bearing blocks, linear bearings, mounting plates, guide shafts, a lifting shaft, a servo motor, a synchronous pulley, a connection plate, a synchronous belt, a synchronous pulley, a pedestal, a connection shaft, a servo motor, a shaft sleeve, a lower end cover, a connection shaft, a shaft sleeve, and an oil cylinder. The automatic carving device for the wheel can automatically carve characters on the wheel, meanwhile it also has the characteristics of simple structure, convenience for manufacturing, stable performance and high precision that can meet the machining requirement, and can also meet the requirement of automatic production.

First claim

The invention claimed is:

1. An automatic carving device for a wheel, comprising: a rack, a chassis, a lifting cylinder, brackets A, bearing seats, 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 connection shaft B, a shaft sleeve B, an oil cylinder, bearings A, end covers, a gland, bearings B, a lower plate, an upper flange plate, pin rolls, springs, sliding petals, a connection shaft C, a protecting cover, a conical 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 knife holder, 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 seats are fixed on the mounting plates, the lifting shaft is installed on the bearing seats 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;
wherein the lower plate is fixed on an upper end of the shaft sleeve A, 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 conical core is connected with the shaft sleeve B via the connection shaft C, the conical 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 upper flange plate is fixed on the lower plate so that eight uniformly distributed T-shaped sliding chutes are formed in an inner cavity enclosed by the upper flange plate and the lower plate, each bottom of the eight sliding pedals is T-shaped to fit in one of the eight T-shaped sliding chutes, the sliding pedals can slide smoothly in the sliding chutes, the inner side wall of each sliding pedal is a slope of 15 degrees relative to a vertical axis of the device, and two ends of each of the eight springs are connected with the upper flange plate and the corresponding sliding pedal respectively; outer side surfaces of the conical core comprise two sets of slopes and the slopes of 15 degrees relative to the vertical axis are uniformly and circumferentially distributed at intervals, the number of slopes of the conical core in each set is eight, two sets of the slopes have a height difference in a direction orthogonal to the vertical axis, side walls of the upper ends of the two sets of slopes join at a conical surface, when the conical core is placed at a lowest position, the inner side walls of the sliding pedals contact the conical surface of the conical core, the servo motor B drives the conical core via the connection shaft B, shaft sleeve B and the connection shaft C rotate 22.5 degrees around the vertical axis, so that when the conical core is driven from the lowest position to a highest position, the inner side walls of the sliding pedals will sequentially contact the conical surface, the set of slopes with a smaller height, and the set of slopes with a larger height; the expanding re; the oil cylinder drives the connection shaft C and the conical core to move up and down, by the slope cooperation of the sliding pedals and the conical core, the eight sliding pedals synchronously move centripetally and centrifugally along the eight uniformly distributed T-shaped sliding chutes; and
wherein 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 holder is installed on the sliding rack B, the carving knife is installed on the carving holder, the servo motor D can drive the sliding rack B, the carving holder and the sliding rack B via the lead screw B to move left or right along the linear guide rail B.

2. The automatic carving device for the wheel according to claim 1 , wherein the lower plate and the upper flange plate are provided with corresponding pin holes, and the pin rolls are connected with the pin holes of the lower plate and the upper flange plate respectively.
