Description
Technical Field
The invention belongs to the technical field of numerical control machining, and relates to a special-shaped circle floating grinding chamfering machine.
Background
For some ceramic products, cast products can generate large out-of-roundness and have different changes in the cooling process due to process reasons. The inner hole chamfering of the products is mostly performed by directly using a grinding head or a cutter for chamfering by adopting a grinding machine or a lathe type rotary machine tool at present, and the chamfering of the products is extremely uneven and has large local part and small local part due to the roundness problem of the products in the chamfering process. And because of the skew in the product clamping process, also can cause the chamfer to be big on one side, small on the other side. Therefore, how to ensure the uniform and consistent sizes of the chamfers is an industrial problem all the time, and partial small-batch products adopt manual chamfers for handheld electric grinding heads, although the manual chamfers have certain flexibility, the manual chamfers are different in size and unsmooth in transition due to the fact that the proficiency difference of people and the action continuity of people are poor, and the efficiency is low, so that the manual chamfers are poor in consistency and are not suitable for large-batch production.

Furthermore, the spare shaft chuck and the chamfering head are clamped and fixed through a three-jaw structure.
Compared with the prior art, the invention has the following advantages:
(1) the conventional inner circle chamfer with a fixed diameter is changed into floating inner circle processing, and the uniformity of the chamfer is greatly improved.
(2) The conventional rigid contact processing of the inner circle chamfer is changed into flexible contact processing. The conditions of product cracking and grinding head damage caused by overlarge feeding amount of the product are greatly reduced.
(3) The condition that the machining allowance is seriously uneven because of product out of round or clamping caused by the traditional machining is changed, and the angle of the floating standby shaft is adjusted along with the allowance, so that the quality can be ensured, the chamfer is even, the cutting time can be greatly shortened, and the efficiency is improved.
(4) The automatic adjustment of the floating head adapts to the change of roundness and the absorption of energy because the cutter and the spare shaft float together, thereby greatly improving the speed and the safety of tool setting.
(5) The change of the traditional processing load quantity is changed along with the size of the feeding and the allowance. The size of feeding is controlled to the weight that adopts the weight, no matter feed and change or the surplus is uneven, because of the weight is in the state of hanging all the time under the support of pulley, according to the balance of force, can keep the cutting force to be unanimous finally to realize high-efficient and even unanimous chamfer effect.
(6) The service life is long: the equipment has simple and reliable structure and no wearing parts, the traction rope uses a thin steel wire rope and a pulley for supporting, and simultaneously, the working surface of the pulley is ground to obtain better surface roughness, so the abrasion is extremely small, thereby greatly prolonging the service life of the equipment.
(7) The equipment can adjust the feeding amount only by increasing or decreasing the weight, is simple to operate and convenient to use, is also suitable for machining outer chamfer parts and the like, and is high in universality and suitable for popularization.
