Description

Power head turntable structure

Technical Field

Background

Today's manufacturing industry has increasingly high demands on the complexity of parts machining and machining accuracy. The multi-station drilling and tapping combined machine tool can complete all working procedures of drilling, chamfering, countersinking, tapping and the like through one-time clamping. The product clamping frequency is reduced, the product clamping time is saved, and the production efficiency is effectively improved. In the field of multi-station combined machine tools, a turntable driven by a servo motor is used as a rotary positioning mechanism, so that the scheme is widely adopted.

The servo turntable which is widely used at present is basically of a worm and gear structure. The servo motor is used for driving the worm to rotate, so that the worm wheel is driven to rotate, and the purpose of driving the turntable to rotate is achieved. However, in the worm and gear mechanism, the worm is made of alloy steel and is hard; the worm wheel is made of aluminum bronze material and is softer. After a period of use, the abrasion of the worm wheel can occur, so that the reverse gap between the worm wheel and the worm is overlarge, and the worm wheel and the worm need to be readjusted, thereby increasing the extra workload of a user.

Secondly, because the worm gear has a self-locking function, if the original point position is set inaccurately, the worm gear can be extruded by the worm gear when the positioning fluted disc is locked, the copper worm gear is damaged, and the mechanism can be seriously disabled. The original point position is accurately set, and the cooperation of mechanical and electrical personnel is also required, so that the whole process is very complex, and the accurate completion of a general user is difficult.

Finally, the position of the servo motor of the turntable with the existing worm and gear structure is basically at one corner of the back of the turntable, and the servo motor is slightly convex, so that the position of a power head of the multi-station combined machine tool can be occupied, and certain trouble is caused to the design layout of the machine tool. In order to prevent the power head from interfering with the servo motor of the turntable, the rotation diameter of the jig disc is forced to be increased, so that the whole size of the machine tool is increased, the whole rigidity of the machine tool is reduced, and the manufacturing cost is increased.
