Description
Technical field
The utility model relates to Machining Technology field, is specifically related to the supporting of universal self-alignment.
Background technology
At home in mechanical processing process, the setting element supported as workpiece is widely used.But day by day complicated along with design of part, machine adds in process and takes more mainly with the processing method of inclined-plane as positioning reference plane, thus is difficult to ensure the install rigidity of workpiece and stable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of modern design, structure rationally, flexible and convenient operation, and automatically can regulate the universal self-alignment supporting of orientation along with the position difference of Workpiece fixing basal plane.
For solving the problems of the technologies described above, the utility model provides following technical scheme: universal self-alignment supporting, comprise base, screw rod, top, top is connected with base by screw rod, one end that screw rod is connected with top is provided with locating slot, the bottom of locating slot is semi-spherical grooves, in locating slot, the top of semi-spherical grooves is T-slot, described top comprises half bulb and support portion, the planar ends in described half bulb is connected with support portion, half bulb on described top is stretched in locating slot, and contact with the semi-spherical grooves in locating slot, top adopts the mode be threaded to screw in the locating slot of screw rod, the radius in described half bulb is greater than the radius in T-slot exit.
On such scheme basis preferably, be provided with circular baffle plate, the diameter of circular baffle plate and the equal diameters in half bulb between described support portion and half bulb, described support portion, rounded stops, half bulb are formed in one structure.
On such scheme basis preferably, the outer surface of described support portion is provided with anti-slip veins.
The beneficial effect that the utility model compared with prior art has is: described screw rod and top adopt sphere-contact and then limit the three degree of freedom of described top, enable described top around X, Y, Z tri-axial-rotations; Described top is fitting in described screw rod process, adopt thread connecting mode, described top is screwed in the groove of described screw rod, screw thread is not in use directly by the effect of workpiece pressure, thus both ensure that the reliability coming directly towards and be connected with screw rod, turn avoid screw thread wearing and tearing in use.The utility model is novel in design, and rationally, flexible and convenient operation, has practical value widely to structure.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model screw-rod structure schematic diagram;
Fig. 3 is the utility model top structure schematic diagram.
Number in the figure is: 1-base, 2-screw rod, 201-semi-spherical grooves, 202-T type groove, and 3-comes directly towards, 301-support portion, 302-circular baffle plate, 303-half bulb.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3 is known, universal self-alignment supporting, comprise base 1, screw rod 2, top 3, top 3 is connected with base 1 by screw rod 2, one end that screw rod 2 is connected with top 3 is provided with locating slot, the bottom of locating slot is semi-spherical grooves 201, in locating slot, the top of semi-spherical grooves 201 is T-slot 202, described top 3 comprises half bulb 303 and support portion 301, the planar ends in described half bulb 303 is connected with support portion 301, half bulb 303 on described top 3 is stretched in locating slot, and contact with the semi-spherical grooves 201 in locating slot, described top 3 adopts the mode be threaded to screw in the locating slot of screw rod 2, the radius in described half bulb 303 is greater than the radius in T-slot 202 exit.
As shown in Figure 2, circular baffle plate 302 is provided with between described support portion 301 and half bulb 303, set up circular baffle plate 302 and can guarantee half bulb 303 directly and T-slot 202 joint, the flexibility ratio in half bulb 303 can be improved like this, to be better positioned on the datum level of inclination, the diameter of circular baffle plate 302 is equal with the radius in half bulb 303, and described support portion 301, rounded stops, half bulb 303 are formed in one structure.
Further, the outer surface of described support portion 301 is provided with anti-slip veins.
Described screw rod 2 adopts sphere-contact with top 3 and then limits the three degree of freedom of described top 3, makes described top 3 can around X, Y, Z tri-axial-rotations; Described top 3 is fitting in described screw rod 2 process, adopt thread connecting mode, described top 3 is screwed in the groove of described screw rod 2, screw thread is not in use directly by the effect of workpiece pressure, thus both ensure that the reliability that top 3 is connected with screw rod 2, turn avoid screw thread wearing and tearing in use.When assembling described top 3, can directly top 3 be screwed in screw rod 2 groove; When using described supporting, supporting can regulate orientation automatically according to the change of Workpiece fixing datum-plane position.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
