Description

Five-axis linkage numerically controlled grinder for rotary file machining

Technical Field

The invention belongs to the technical field of numerical control machine tools, and particularly relates to a five-axis linkage numerical control grinding machine for rotary file machining.

Background

The cemented carbide rotary file has wide application, and has a large number of applications in the fields of machinery, aviation, automobiles, ships, chemical industry, process engraving and the like, for example: finish machining various metal mold cavities, such as shoe molds and the like; engraving various metals and non-metals, engraving art gifts, etc.; cleaning flash, burrs and welding seams of casting, forging and welding parts, such as shipbuilding factories, automobile factories and the like; chamfering and groove processing, pipeline cleaning, and finishing of the inner hole surfaces of mechanical parts, such as machinery factories, repair factories and the like; and (3) polishing the runner part of the impeller, such as an automobile engine factory and the like.

The production process of the hard alloy rotary file approximately comprises the following steps: mixing, drying, selecting materials, pressing and forming, selecting blank materials, sintering, grinding and forming head lines and forming; in the process of processing and forming the head lines, a five-axis linkage numerical control grinder of key equipment is needed. During processing, the ground rotary file is arranged on the A shaft of the supporting platform, the head of the rotary file is processed by utilizing the grinding wheel arranged on the swing arm, and meanwhile, the contact part of the grinding wheel and the rotary file is sprayed with cooling oil for real-time cooling. However, the conventional five-axis linkage numerical control grinder has the following defects:

(1) The support platform is fixed on the grinder base, so that the base level needs to be kept at any time to ensure the machining precision, so that the machining precision is not influenced, the levelness of the traditional base is very troublesome to adjust, and the levelness of the traditional base cannot be accurately adjusted; in the course of working, accompanied by the rotation of grinding wheel, whole equipment is in incessant vibration state, and is higher to the stability requirement of base, and traditional base's structural stability is relatively poor, under the condition of long-term vibration, life is short, and the screw of connecting each part is easy not hard up to produce little displacement, and then influences machining precision.

(2) In the processing process, the support platform can move along the X direction and the Y direction to adjust the position of the rotary file, but the moving position of the traditional support platform cannot be accurately controlled, the operation is not stable enough, and the processing precision is affected.

(3) The transmission mechanism of the traditional A-axis structure adopts a turbine worm, the transmission ratio is small, the rotation efficiency is low, the bearing capacity is small, the return clearance is large, and the precision of the structure is low; the clamping head is not tightly connected with the pull rod, and is usually fastened on the pull rod, so that the clamping head is easy to fall off in the production and use process, and is not suitable for long-time connected processed products.

(4) The traditional swing arm structure is either too high in cost, complex in structure or too low in precision, low in efficiency and incapable of guaranteeing the operation requirement under high precision for a long time; and the lifting of the electric spindle is inconvenient to control, the gap between the whole swing arm structures is large, and the precision is low. In the operation process, manual control is usually needed, so that the labor intensity of workers is high, the polishing speed is low, the polishing efficiency is low, and the batch production is not facilitated; the consistency of products at the production place is poor, and the subsequent processing is easy to influence, thereby influencing the whole production line.

(5) In the grinding process, high heat is often generated, so a cooling device is needed, and the cooling operation is performed while grinding in the grinding process; the existing cooling system for the numerically controlled grinder adopts the oil tank to directly spray at the grinding position, but the detection of the oil quantity in the oil tank can not be carried out in the cooling process, so that if the oil tank is not sprayed, the grinding device is used for grinding, the grinding effect is affected, and meanwhile, the service life of equipment is more lost; in addition, the existing cooling system for the numerically controlled grinder cannot recover the oil after spraying and using, so that the cost is wasted, and the resource utilization rate is reduced.

(6) Since the cooling oil is sprayed for real-time cooling during processing, fire prevention in the working environment is very important, and once a fire disaster occurs, the fire disaster can spread rapidly, so that great loss is caused.
