Description

The main tapping precision adjustment unit

Technical field

The utility model provides a kind of technical field of toolroom machine, and espespecially it technically provides a kind of device of adjusting the tool machine spindle beat, coordinates by first and second nut and adjusts bolt, reaches quick, easy correction main shaft beat and joint space-efficient effect.

Background technology

see also shown in Fig. 5-Fig. 5 B, the toolroom machine of commonly using has a main tapping 81 usually, this main tapping 81 is located on a platform 83 and its inside is provided with a main shaft 82 rotationally, the cumulative limit that produces because of each member, perhaps use after after a while in toolroom machine, make this main shaft 82 depart from predeterminated position originally, and cause not problem accurately of processing, therefore need to utilize two adjusting devices 9 to adjust, one of them this adjusting device 9 is positioned at an end of this main tapping 81 sides, another this adjusting device 9 is positioned at the other end of this main tapping 81 sides, respectively this adjusting device 9 comprises that being equipped with one first on a fixture 91 adjusts bolt 92 and one second adjustment bolt 93, by rotate this first, two

adjust bolt

92, 93, can push away or pull respectively this main tapping 81 to proofread and correct the deflection angle θ of this main shaft 82, yet, this adjusting device 9 of commonly using is carrying out timing, before this first adjustment bolt 92 promotes these main tappings 81, must first rotate this second adjustment bolt 93 makes its bolt head remove from this fixture 91, just rotatable this first adjustment bolt 92 carries out the beat correction of this main shaft 82 to promote this main tapping 81, otherwise, before this second adjustment bolt 93 pulls this main tapping 81, must first rotate this first adjustment bolt 92, it is removed from this main tapping 81, just rotatable this second adjustment bolt 93 is proofreaied and correct to pull this main tapping 81 to carry out this main shaft 82 beats, has the loaded down with trivial details problem of set-up procedure, and each this adjusting device 9 needs two different spare parts just can push away or pull this main tapping 81, have number of components mainly with and take the problem in available space on toolroom machine, the deflection angle θ correction that adds this main shaft 82 of tradition needs two adjusting devices 9 of operation, therefore have long problem of adjustment time, the necessity that is improved is arranged in fact.

The shortcoming of prior art: tradition is carried out main shaft deflection angle timing, must operate two adjusting devices to adjust, has the problem that set-up procedure is loaded down with trivial details and the adjustment time is long, and each this adjusting device needs two different spare parts just can push away or pull this main tapping, have number of components mainly with and take the problem in available space on toolroom machine.

Summary of the invention

The purpose of this utility model is, a kind of main tapping precision adjustment unit is provided, the defective that exists to solve prior art, and it is simple in structure, and is easy to operate, can reach quick, easy correction main shaft beat and save space and cost.

For achieving the above object, the utility model provides a kind of main tapping precision adjustment unit, it is characterized in that, includes:

One main shaft headstock, this main shaft headstock are located on the bed platform of work table and supports main shaft, and this main shaft headstock appropriate position is arranged with an internal thread segment;

One fixture, this fixture are locked on the bed platform of work table, and this fixture runs through an axis hole;

One adjusts bolt, and this adjustment bolt comprises an external thread section, and this external thread section passes this internal thread segment that is screwed together in this main shaft headstock after this axis hole of this fixture;

One first nut, this first spiro cap locks in this external thread section of this adjustment bolt, and this first nut is positioned at the side that this fixture differs from this main shaft headstock; And

One second nut, this second spiro cap locks in this external thread section of this adjustment bolt, and this second nut is positioned at a side of contiguous this main shaft headstock of this fixture; By this, by rotating this first nut and this main shaft headstock Linear-moving of this second nut capable of regulating.

Wherein, more sheathed one first pad of this external thread section and one second pad, this first pad are between this fixture and this first nut, and this second pad is between this fixture and this second nut.

Wherein, this external thread section is lock set 1 the 3rd nut more, and the 3rd nut is resisted against this main shaft headstock, and this external thread section and this internal thread segment are closely cooperated and gapless.

effect against existing technologies: of the present utility model first, two pads can prevent first, two nuts are directly supported fixture, reach and avoid fixture and first, the effect of two nut wearing and tearing, be docile and obedient clockwise by instrument and rotate the first nut, or rotate this second nut according to counterclockwise, make adjust bolt drive the main shaft headstock near or move away from the direction of fixture, allow the axial line of main shaft be positioned at the tram, reach quick, the easy effect of completing the correction of main shaft beat, the quantity that adds adjustment bolt of the present utility model only needs one, need not use multiple types of tools to adjust, has the few and joint space-efficient effect of number of components.
