A drive gear shaft clamping tool for a shield machine, which is characterized in that: it comprises an inner cone sleeve whose upper inner hole is a tapered hole and an outer side surface is a threaded structure, which is fixed on the upper part of the bottom bracket through a connecting piece, and is sleeved on the inner cone sleeve. The outer taper sleeve in the outer taper sleeve is matched with the claw set on the inner wall of the upper locking cover through the annular slot machined at the upper end of the outer tapered sleeve, and the upper locking cover is screwed into the inner wall through the connecting piece and in a threaded manner. Combined with the lower locking cover on the outer thread section of the taper sleeve.
Description
Technical Field
The invention relates to a tool suitable for improving machining of deep-hole shaft parts for a shield machine, which greatly improves the machining operation convenience and gear grinding efficiency of the deep-hole shaft parts.
Background
The gears of the shield machine depend on import for a long time, the gears are in urgent need of being made into a country gradually, the 13003000300 shield planetary gear structure is complex, the processing manufacturability of gear grinding is poor, and two methods are adopted for the conventional grinding clamp:
1. the inner spline end is sleeved into the outer spline to enable the inner spline and the outer spline to form tight fit.
2. A section of the center hole of the internal spline is supported by a lengthened tip, and the periphery of the center hole is fixed to move circumferentially by a chicken heart card.
The matching sizes of the inner spline and the outer spline cannot be consistent, and gaps exist, so that the alignment is difficult. The rigidity of the lengthened tip is poor, elastic deformation often occurs in the grinding process, and the requirement of a drawing is difficult to achieve. Through detection, the two machining clamps grind 65 gears, 11 products are completely qualified, and most of the products cannot meet the requirements of drawings.
From the past processing error analysis, because the clamping rigidity of a part of gears is not enough, and a part of gears are not standard because the center hole at one end is positioned at the inner side of the internal spline and is 135mm away from the end surface, the processing difficulty is higher, the gear module is large, the tooth width is wide, the grinding force enables the gears to be deformed during grinding, and discarding the center hole positioning grinding teeth becomes an option to be considered.
Disclosure of Invention
The invention aims to provide a shield tunneling machine driving gear shaft fixture tool aiming at the defects in the prior art.
The object of the invention can be achieved by the following technical measures:
the shield machine driving gear shaft fixture tool comprises an inner taper sleeve and an outer taper sleeve, wherein an upper inner hole fixedly connected above a bottom support through a connecting piece is a taper hole, the outer side surface of the inner taper sleeve is of a threaded structure, the outer taper sleeve is sleeved in the inner taper sleeve, the outer taper sleeve is matched with a clamping jaw arranged on the inner wall of an upper locking cover through an annular clamping groove machined in the upper end of the outer taper sleeve, and the upper locking cover is combined with a lower locking cover which is screwed on an outer threaded section of the inner taper sleeve in a threaded matching mode through the connecting piece.
The outer taper sleeve is symmetrically divided along the circumference of the outer taper sleeve, a plurality of upper open grooves used for better holding a workpiece are cut from top to bottom, and the distance between the bottom of each upper open groove and the bottom of the outer taper sleeve is 20-30 mm.
The lower end of the inner taper sleeve is arranged above the bottom support through a countersunk head screw.
The working principle of the invention is as follows:
after the workpiece is hoisted to an inner hole of an assembly part (an outer taper sleeve), the upper locking cover is rotated to enable the upper locking cover and the lower locking cover to move downwards simultaneously and drive the outer taper sleeve to move downwards. And (4) after the machining is finished, loosening the upper locking cover, further moving the outer taper sleeve upwards, finally loosening the inner diameter of the outer taper sleeve and the outer diameter of the workpiece, hanging the workpiece away, and finishing the machining.
The invention has the following beneficial effects:
the fixture tool provided by the invention has the advantages that the workpiece is tightly held in the inner hole by rotating the upper locking cover and the lower locking cover and utilizing the conical surface relation of the inner taper sleeve and the inner taper sleeve, the bus of the workpiece is aligned, the convenient machining on a machine tool and the improvement of the machining efficiency and precision of the machine tool are realized, the structure is simple and practical, the fixture is convenient and safe to mount and clamp, the accuracy grade of the gear machined by adopting the fixture tool can be greatly improved, and the precision can be kept from being reduced after the fixture tool is repeatedly used.

Detailed Description
As shown in fig. 1, the shield machine driving gear shaft clamp tool of the present invention includes an inner taper sleeve 1 (see fig. 6) fixedly connected to the upper portion of a bottom base 3 (see fig. 2) through a countersunk screw, wherein an upper inner hole is a taper hole, an outer side surface is a thread structure, an outer taper sleeve 5 (see fig. 5) sleeved in the inner taper sleeve 1, the outer taper sleeve 5 is matched with a clamp claw (clamp table) arranged on the inner wall of an upper lock cover 4 through an annular clamp groove processed at the upper end of the outer taper sleeve 5, and the upper lock cover 4 (see fig. 3) is combined with a lower lock cover 2 (see fig. 4) screwed on an outer thread section of the inner taper sleeve in a thread matching manner through a connecting piece.
Four upper open grooves for better holding a workpiece are cut from top to bottom along the circumference of the outer taper sleeve 5 in a symmetrical segmentation mode, and the distance between the bottom of each upper open groove and the bottom of the outer taper sleeve is 20-30 mm (see fig. 5).
