Embodiment Construction

[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0029] see figure 1 , the stepless indexing device of the preferred embodiment of the present invention includes a synchronous belt 1, a servo motor 2, a stretching and tightening device 3, a push cylinder 4, a large pulley 5, a rear bearing seat 6, a hollow main shaft 7, and a long key 8. Cam template 9, front bearing seat 10, joint 11 and indexing dial 12.

[0030] The two ends of hollow main shaft 7 are equipped with front bearing seat 10 and rear bearing seat 6 respectively, between front and rear bearing seat 10,6, are fixedly installed with some cam templates 9 of different linear shapes by a long key 8. One end of the front bearing seat 10, that is, the inner hole of the head of the hollow main shaft 7 is provided with a stepped hole 71, and...

Abstract

The invention provides a stepless dividing device and a camshaft grinder comprising the same. The stepless dividing device comprises a servo motor (2), a hollow spindle (7) arranged between two bearing seats (6 and 10), a cam sample plate (9) fixedly connected onto the hollow spindle (7) and a dividing driving plate (12) movably sleeved on the head portion of the hollow spindle (7). The stepless dividing device is characterized in that a pulling tight set device for driving the hollow spindle (7) to be connected or disconnected with the dividing driving plate (12) is arranged in an inner hole of the hollow spindle (7), a pipe bending cylinder (4) for pushing the pulling tight set device (3) is sleeved on the tail portion of the hollow spindle (7), and a disc braking device for locking the dividing driving plate (12) is further arranged outside the dividing driving plate (12). The dividing driving plate (12) has the advantages of being simple in structure, easy to manufacture, capable of dividing at any angle, fast in dividing and high in accuracy.

Description

technical field [0001] The present invention relates to the field of metal processing equipment, in particular, to a stepless indexing device, including a servo motor, a hollow shaft installed between two bearing seats, a cam template fixed on the hollow main shaft and a looper on the hollow main shaft Head indexing dial. In addition, the present invention also relates to a camshaft grinder comprising the stepless indexing device. Background technique [0002] The camshaft is one of the key parts of the automobile engine. Its quality and machining accuracy directly affect the emission, energy saving and service life of the engine. [0003] In the prior art, most cam manufacturers still widely use mechanical profiling camshaft grinders to profile camshaft parts. The accuracy of the cam profile of the camshaft is directly affected by the manufacturing accuracy of the camshaft template. The cams of the processed products are in one-to-one correspondence, that is to say, if th...
