Abstract
The utility model relates to a thermal elongation treating structure of a spindle, particularly a spindle core thermal elongation treating assembly structure used for a ball high-speed electric spindle of a machine tool. In the thermal elongation treating structure, a steel ball bush (2) is arranged at the contact part of the outer wall of a bearing block (1) and the inner wall of a machine body (4); a spindle core step (5) is arranged at the lower part of a spindle core (3) and abutted against the upper surface of a lower bearing (6); a bearing outer ring locking nut (7) is arranged between the lower end surface of the lower bearing (6) and the lower part of the spindle core (3); and a bearing inner ring locking nut (8) is arranged at the lower part of the bearing outer ring locking nut (7). By using the thermal elongation treating structure, the service life of the spindle core can be prolonged, the deformation of the spindle core can be prevented, the service life of the bearing can be prolonged and the cost is reduced; and the thermal elongation treating structure is convenient for popularization and application.
Description
Technical field
The utility model relates to a kind of machining equipment, specifically a kind ofly is used for the axle core thermal stretching processing components structure that mechanical processing machine ball high-speed electric main shaft uses.
Background technology
In the prior art, the situation of thermal stretching can take place because of the high speed rotation in the axle core that main shaft is used, and the appearance of this situation often causes a core distortion, makes bearing damage easily, and the main shaft cisco unity malfunction.
Summary of the invention
The utility model relates to a kind of thermal stretching of main shaft and handles structure, and it can prolong the service life of a core, stops the distortion of axle core, prolongs bearing service life, reduces cost, and is convenient to promote and use.
The utility model technical solution is in existing bearing seat (1), axle core (3), on the basis of body (4) lower bearing (6), the utility model is provided with steel ball sleeve (2) particularly in bearing block (1) outer wall and body (4) inwall touching position, the upper surface that the bottom of axle core (3) is provided with a core step (5) and lower bearing (6) offsets, be provided with bearing outer ring locking nut (7) between the lower surface of lower bearing (6) and axle core (3) bottom, bearing outer ring locking nut (7) bottom is bearing inner race locking nut (8).
The utility model operation principle is that bearing outer ring locking nut (7) is threaded with body (4) and bearing inner race locking nut (8) is threaded with axle core (3), make lower bearing (6) be fixed in the body place, when axle core (3) rotation, when energising produces thermal stretching, axle core step (5) is located to be subjected to lower bearing (6) and is hindered, thereby cause a core (3) and bearing block (1) integral body to move up, because the existing of steel ball sleeve (2) (steel ball sleeve is very little with the body friction), thereby solved core (3) thermal stretching problem that moves up.
Advantage of the present utility model is:
1. this structure can prolong the life-span of a core, has avoided thermal stretching to be subjected to resistance and produced a core being out of shape;
2. this structure can prolong the life-span of bearing;
3. that rotating shaft is worked together is more flexible for this structure.
Description of drawings
Fig. 1 is a profile construction schematic diagram of the present utility model.
The specific embodiment
According to shown in Figure 1, the utility model is at existing bearing seat 1, axle core 3, on the basis of body 4 lower bearings 6, bearing block 1 outer wall and body 4 inwall touching positions are provided with steel ball sleeve 2, the upper surface that the bottom of axle core 3 is provided with a core step 5 and lower bearing 6 offsets, and is provided with bearing outer ring locking nut 7 between the lower surface of lower bearing 6 and axle core 3 bottoms, and bearing outer ring locking nut 7 bottoms are bearing inner race locking nut 8.
Claims (1)
1. structure is handled in the thermal stretching of a main shaft, it has comprised bearing block (1), axle core (3), body (4) lower bearing (6), it is characterized in that bearing block (1) outer wall and body (4) inwall touching position are provided with steel ball sleeve (2), the upper surface that the bottom of axle core (3) is provided with a core step (5) and lower bearing (6) offsets, be provided with bearing outer ring locking nut (7) between the lower surface of lower bearing (6) and axle core (3) bottom, bearing outer ring locking nut (7) bottom is bearing inner race locking nut (8).
