b. During the continued rotation of the cam plate 315 by 180 degrees (i.e., during the rotation of the cam plate 315 from 90 degrees to 270 degrees), i.e., during the sliding of the sliding round bar 320 within the proximal end of the cam plate 315 (i.e., the curved surface of the cam plate 315 having a larger radius), the sliding round bar 320, the straight bar 318, and the locking round bar 321 do not undergo linear movement in the straight direction of the straight bar 318 (i.e., the straight direction from the sliding round bar 320 to the locking round bar 321) (when the locking round bar 321 is disengaged from the driven round disc 311), while during the sliding of the sliding round bar 320 within the proximal end of the cam plate 315 (i.e., the curved surface of the cam plate 315 having a larger radius), The driving plate 316 is abutted against the inner wall of the radial groove 312 through the cylindrical pin 317, so that the cylindrical pin 317 drives the driven disc 311 to rotate 72 degrees through the radial groove 312 (since five radial grooves 312 and five inner concave locking arcs 313 are uniformly arranged in the circumferential direction of the driven disc 311, the intermittent angle between each adjacent radial groove 312 and inner concave locking arc 313 is 72 degrees, so that when the cylindrical pin 317 drives the driven disc 311 to rotate through the radial groove 312, the rotation angle of the driven disc 311 is 72 degrees), the driven disc 311 drives the cutter-loading disc 39 to rotate 72 degrees through the driven shaft 38, the cutter loading circular plate 39 drives the inner ring cutter, the rough turning cutter, the finish turning cutter and the outer ring cutter to synchronously rotate for 72 degrees, so that the rough turning cutter is aligned to the circle center position of the belt pulley; c. During continued rotation of the cam plate 315 through 90 degrees (i.e., rotation of the cam plate 315 from 270 degrees to 360 degrees), by sliding the sliding rod 320 along the trajectory of the cam plate 315 (i.e., sliding the sliding rod 320 from the proximal end of the cam plate 315 to the distal end of the cam plate 315 (i.e., sliding the sliding rod 320 along the trajectory of the curved slot connecting between the proximal end of the cam plate 315 and the distal end of the cam plate 315), as the sliding rod 320 slides within the curved slot of the cam plate 315, the sliding rod 320 drives the straight rod 318 to slide away from the center of the driven disc 311, The straight rod 318 drives the locking round rod 321 to slide into the radial groove 312 (that is, the radial groove 312 opposite to the straight rod 318 after the driven disc 311 rotates 72 degrees), so that the locking round rod 321 performs locking operation on the driven disc 311 (the locking round rod 321 slides into the radial groove 312 from the outside of the radial groove 312, so that the driven disc 311 cannot rotate, that is, performs locking operation on the driven disc 311), meanwhile, in the process that the sliding round rod 320 slides in the curved groove on the cam disc 315, the cam disc 315 drives the driving dial 316 to rotate 90 degrees clockwise, at this time, the inner concave locking arc 313 on the driven disc 311 is blocked by the driving plate 316, so that the driving plate 316 locks the driven disc 311, the driven disc 311 is double-locked by the driving plate 316 and the locking circular rod 321 through the mutual matching of the locking circular rod 321 and the radial groove 312 and the mutual matching between the inner concave locking arc 313 and the driving plate 316, the locking effect of the driven disc 311 after rotating and changing the cutter is improved, the rough turning cutter is prevented from rotating when the belt pulley is processed, at the moment, the position of the second sliding rail 32 in the first sliding rail 31 and the position of the U-shaped frame 33 in the second sliding rail 32 are adjusted, The position of the rough turning cutter for rough turning of the belt pulley is adjusted through the position of the U-shaped frame 33, so that the stability and the accuracy of rough turning of the belt pulley are improved, and after the rough turning of the belt pulley is finished, the rough turning cutter is separated from the belt pulley; (3) When the belt pulley is subjected to finish turning, repeating the rough turning step, so that the finish turning cutter performs finish turning operation on the belt pulley; (4) When the outer ring of the belt pulley is processed, the rough turning processing steps are repeated, so that the outer ring cutter can process the outer ring of the belt pulley, the belt pulley can be processed and molded once, the belt pulley is not required to be decomposed and produced through a plurality of working procedures, repeated loading and unloading operations and additional circulation working procedures are reduced, and the processing efficiency and the processing quality of the belt pulley are improved.
The annular frame body 1 is provided with the V-shaped plate 16 that stands upside down on being located the outer wall of outer loop holder 11 same side, specifically, when the belt pulley carries out the processing operation of inner ring or outer loop, the piece that produces when the belt pulley processing slides the annular frame body 1 outside through V-shaped plate 16, prevents that the piece from causing the influence to the processing of belt pulley to be convenient for collect.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the invention, which is defined by the appended claims.
