Abstract

The invention discloses a method of boring a worm gear. A dedicated mold is fixed on a boring lathe. According to the position of a threaded hole of a to-be-machined worm gear, a boring mold of the dedicated mold is manufactured. The to-be-machined worm gear is arranged on a rotatable base plate of the dedicated mold and an inner hole of the worm gear is enabled to penetrate through a revolving shaft and be sleeved on a boss of the rotatable base plate. A pressure plate is arranged on the upper portion of the boring mold. By arranging a press nut on the revolving shaft, the press plate is enabled to press the boring mold and the to-be-machined worm gear on the rotatable base plate. A drill of the lathe is directed at a hole position of the boring mold and performs boring. After a hole is finished, the position of the drill is kept unchanged, the rotatable base plate is rotated, the drill of the lathe is directed at another hole position of the boring mold and performs boring till all holes are machined. The press nut is loosened, the worm gear is taken off and boring the worm gear is finished. The method of boring the worm gear can improve working efficiency, reduce labor cost, improve product precision and ensure product quality.

A kind of method of worm gear boring
Technical field
The present invention relates to a kind of worm gear processing method, specifically a kind of method of worm gear boring.
Background technology
In the worm gear product, the all equal portions arrangements centered by a center of circle of its screw hole, traditional worm gear drilling method is: the position that at first needs to hole on worm gear marks, and then worm gear is fixed on drilling machine, and mark position of drill bit is holed, after complete in this hole, rotary drill bit, make drill bit again aim at next mark position again, then carry out drilling operation, so repeat, until porose completing.The shortcoming of this method is: drilling efficiency is low, inconvenient operation; Owing to will ceaselessly aiming the place, defective work easily appears in poor accuracy.
Summary of the invention
The problem that exists in order to overcome prior art the purpose of this invention is to provide a kind of method that worm gear is holed, and adopts the method can increase work efficiency, reduce labour cost; Improve Product Precision, guarantee product quality.Particularly efficient is higher when the drilling machine operation surpasses the workpiece of drill boom length.
The objective of the invention is to be achieved through the following technical solutions:
A kind of method of worm gear boring is characterized in that the method comprises the following steps:
1) particular manufacturing craft is fixed on drilling machine; This mould comprises fixed base plate, pivotable sole plate, drill jig, pressing plate and rotating shaft, and rotating shaft is vertically set on fixed base plate, and pivotable sole plate is sleeved in rotating shaft and is arranged on rotationally on fixed base plate by bearing; Be provided with the boss suitable with the worm gear endoporus in the upper surface of pivotable sole plate, drill jig is fixed on boss by pressing plate, and drill jig and pressing plate all are sleeved in rotating shaft; Particular manufacturing craft is fixed on drilling machine by fixed base plate;
2) make the drill jig of particular manufacturing craft according to worm gear to be processed the tighten up a screw position in hole, guarantee that in the position of drill jig mesopore and worm gear, the screw hole position is identical;
3) worm gear to be processed is placed on the pivotable sole plate of particular manufacturing craft, and makes the worm gear endoporus pass shaft set on the boss of pivotable sole plate;
4) pressing plate is placed on drill jig top, by being arranged on the clamp nut in rotating shaft, pressing plate is pressed on drill jig and worm gear to be processed on pivotable sole plate;
5) drilling operation is carried out in the position in a hole in drilling machine drill bit drill jig; After completing a hole, keep bit location constant, rotate pivotable sole plate, then drilling operation is carried out in the position in another hole in drilling machine drill bit drill jig, until porose machining;
6) unclamp clamp nut, take off worm gear, complete worm gear boring.
In the present invention, described particular manufacturing craft is provided with step in the upper surface of fixed base plate, is provided with the groove suitable with step in the lower surface of pivotable sole plate, and bearing is arranged on outside step.
The present invention is directed to the worm gear screw hole and be all the characteristics that equal portions are arranged centered by a center of circle, the fixing position of fluted drill during boring is rotated worm gear and is punched.Compared with prior art, high efficiency of the present invention has reduced labour cost; Improve Product Precision, guaranteed product quality.The present invention is specially adapted to surpass in the workpiece of drill boom length in the drilling machine operation.
Description of drawings
Fig. 1 is the structural representation of special-purpose mould in the present invention.
The specific embodiment
A kind of method of worm gear boring, the method comprises the following steps:
1) particular manufacturing craft is fixed on drilling machine; This particular manufacturing craft is seen Fig. 1, comprises fixed base plate 1, pivotable sole plate 2, drill jig 3, pressing plate 4 and rotating shaft 5, and rotating shaft 5 is vertically set on fixed base plate 1, and fixed base plate 1 is circular, and rotating shaft 5 is positioned at home position.Pivotable sole plate 2 is sleeved in rotating shaft 5 and by bearing 6 and is arranged on rotationally on fixed base plate 1.Be provided with step 11 in the upper surface of fixed base plate 1, be provided with the groove 21 suitable with step 11 in the lower surface of pivotable sole plate 2, bearing 6 is arranged on step 11 outsides, and bearing can be plane bearing.Be provided with the boss 22 suitable with worm gear 7 endoporus in the upper surface of pivotable sole plate 2, the drill jig 3 suitable with the screw hole of worm gear is fixed on boss 22 by pressing plate 4, and drill jig 3 and pressing plate 4 all are sleeved in rotating shaft 5.Top in rotating shaft 5 is provided with screw thread, and is set with clamp nut 8, by the compression of 8 pairs of pressing plates 4 of clamp nut, drill jig 3 is fixed on worm gear to be processed, and particular manufacturing craft is fixed on drilling machine by fixed base plate;
2) make the drill jig of particular manufacturing craft according to worm gear to be processed the tighten up a screw position in hole, guarantee that in the position of drill jig mesopore and worm gear, the screw hole position is identical;
