Abstract
The utility model relates to a locking mechanism for a revolving shaft of a machine tool and belongs to the technical field of metal cutting machines. The locking mechanism comprises a locking disc, an adjusting mechanism, a spring return mechanism and a locking cylinder. The locking disc, an upper adjusting pad and a lower adjusting pad are arranged a revolving main shaft and the locking disc and the adjusting mechanism are formed. The upper adjusting pad and the lower adjusting pad are repaired so that the axial position of the locking disc by thicknesses of upper adjusting pad and the lower adjusting pad. The spring return mechanism and the locking cylinder are arranged on a box body of the revolving shaft. The spring return mechanism comprises an installation base and a spring. The spring is arranged in the installation base. The locking cylinder comprises a cylinder body and a piston. The cylinder body and the installation base are connected with the box body via bolts. The piston is arranged in the cylinder body. The locking mechanism for the revolving shaft of the machine tool has following advantages: axial locking structure is adopted for locking the revolving shaft; and the locking mechanism is compact in structure, convenient in adjustment, adjustable in locking force and good in locking rigid.
Description
Technical field
The utility model relates to a kind of machine tool rotary shaft locking mechanism, belongs to Metal Cutting Machine Tool equipment technical field.
Background technology
Domestic multi-shaft interlocked metal cutting Digit Control Machine Tool is more and more at present, especially with the multi-shaft interlocked Digit Control Machine Tool of gyroaxis, constantly applies.Along with the processing request of the Complex Surface Parts such as space curved surface is more and more higher, metal cutting Digit Control Machine Tool not only requires gyroaxis (comprising A axle, B axle, C axle) and other linear axis interlocks, also requires gyroaxis can realize locking at any angle.Before the utility model patent application day, the gyroaxis of domestic metal cutting Digit Control Machine Tool does not much possess locking function at any angle, some locking functions are applied radially retaining mechanism, radially retaining mechanism takies axial dimension, rotary main shaft is lengthened, thereby reduced gyroaxis rigidity, requirement on machining accuracy to rotary main shaft and radially locking use gripping sleeve is high, be difficult to adjust, locking effect is poor, and takies a large amount of lathes space.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of machine tool rotary shaft locking mechanism, locking effect is good, take axial dimension little, install easy to adjust, can realize gyroaxis and lock at any angle.
A shaft locking mechanism, comprises locking plate and guiding mechanism, spring return function mechanism, locking cylinder; Locking plate, upper adjusting pad and lower adjusting pad are arranged on and on rotary main shaft, form locking plate and guiding mechanism; By adjusting pad, lower adjusting pad in repair, by the thickness of upper adjusting pad, lower adjusting pad, adjusted the axial location of locking plate; Spring return function mechanism and locking cylinder are arranged on the casing of gyroaxis; Spring return function mechanism comprises mount pad and spring, and spring is contained in mount pad; Locking cylinder comprises cylinder body and piston; By bolt, cylinder body is connected with casing with mount pad, piston is arranged in cylinder body.
The utility model has the advantages that and adopt the structure of axial locking to lock gyroaxis, compact conformation, is convenient to adjust, and coupling mechanism force is adjustable, locking good rigidly.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, does not form to improper restriction of the present utility model, as shown in the figure:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of machine tool rotary shaft locking mechanism, comprises locking plate and guiding mechanism, spring return function mechanism, locking cylinder; Locking plate 6, upper adjusting pad 7 and lower adjusting pad 8 are arranged on rotary main shaft 9, form locking plate and guiding mechanism; By adjusting pad in repair 7, lower adjusting pad 8, by the varied in thickness of adjusting pad, adjusted the axial location of locking plate 6; Spring return function mechanism and locking cylinder are arranged on the casing 1 of gyroaxis; Spring return function mechanism comprises mount pad 2 and spring 3 (can be stage clip or dish spring), and spring 3 is contained in mount pad 2; Locking cylinder comprises cylinder body 4 and piston 5; By bolt, cylinder body 4 and mount pad 2 are connected to casing 1, piston 5 is arranged in cylinder body 4.
The occupation mode of the utility model machine tool rotary shaft locking mechanism is as follows:
Arbitrarily angled at gyroaxis, when gases at high pressure or hydraulic oil enter locking cylinder, promote the piston in cylinder body, piston contacts and promotes locking plate, locking plate is pressed on the mount pad of spring return function mechanism, realizes gyroaxis axial locking at any angle.When gases at high pressure or hydraulic oil release, spring return function mechanism urges piston, unclamps locking plate, and gyroaxis can arbitrarily rotate.
By the contact area of locking plate and mount pad, and the size of definite coupling mechanism forces such as pressure of gases at high pressure or hydraulic oil.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
