Description
Technical field
The present invention relates to a kind of supporting construction, particularly a kind of worm and gear electric lock ball chuck compact schemes structure.
Background technology
When carrying out the support of some large-scale workpiece, need after having supported to lock supporting construction or support system, the locking of conventional support structure often relies on pneumatic control, and its coupling mechanism force is difficult to control, and without self-locking performance; And sometimes need supporting construction can make adaptive adjustment along with workpiece, to eliminate stress, and traditional supporting construction is fixed after support, and such stress will be applied on workpiece, there is potential safety hazard, affects workpiece quality.
Summary of the invention
The present invention is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, can carry out the worm and gear electric lock ball chuck compact schemes structure of adaptive adjustment while clamping, support workpiece as required.
Technical solution of the present invention is: a kind of worm and gear electric lock ball chuck compact schemes structure, comprise cylindric housing 1, it is characterized in that: housing 1 internal fixtion is provided with ball seat 2, be spherical groove in ball seat 2, three are embedded with in circumferentially equally distributed clamping balls 3 at the sidewall of ball seat 2, also worm gear 4 is provided with rotationally in housing 1 outside ball seat 2, inner sleeve 5 is connected with above worm gear 4, inner sleeve 5 is provided with three inner sleeve grooves 6 matched with clamping balls 3, the worm screw matched with worm gear 4 is then arranged on the working end of motor 7, what match with the spherical groove in ball seat 2 is provided with the ball 8 that is locked, the be locked top of ball 8 is connected with backstay 9.
Described housing 1 is also provided with target ball 10.
Described target ball 10 is multiple, and is uniformly distributed on housing 1.
Compared with the existing technology, tool has the following advantages in the present invention:
The worm and gear electric lock ball chuck compact schemes structure of this kind of version, its structure is simple, design ingenious, rationally distributed, it is easily produced the problem of stress when supporting for large-scale workpiece, design a kind of supporting construction automatically can carrying out accommodation within the specific limits according to workpiece stressing conditions, it adopts the form of sphere-contact, be convenient to adjust angle, make workpiece clamping while can according to required adjustment proper angle, locking effect is good, coupling mechanism force is controlled, and safeguard simple, the clamping of different institutions type can be adapted to, its part is convenient to change, and the target ball measurement point that it is arranged turn increases the accuracy of clamping and positioning.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.

Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Fig. 3 is the perspective view of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.As shown in Figure 1 to Figure 3: a kind of worm and gear electric lock ball chuck compact schemes structure, comprise the housing 1 based on, this housing 1 is cylindric, housing 1 internal fixtion is provided with ball seat 2, spherical groove is offered in this ball seat 2, the sidewall of the ball seat 2 above spherical groove is embedded with three in circumferentially equally distributed clamping balls 3, worm gear 4 is also provided with in housing 1 outside ball seat 2, and worm gear 4 can and housing 1 between relatively rotate, inner sleeve 5 is connected with above worm gear 4, inner sleeve 5 then offers three inner sleeve grooves 6, and these three inner sleeve grooves 6 match respectively with three clamping balls 3, what match with worm gear 4 is provided with worm screw, this worm screw is then arranged on the working end of motor 7, what match with the spherical groove offered in ball seat 2 is also provided with the ball 8 that is locked, backstay 9 is then connected with above the ball 8 that is locked, housing 1 is also provided with multiple equally distributed target ball 10.
The process of the worm and gear electric lock ball chuck compact schemes structure of the embodiment of the present invention is as follows: when needs clamp large-scale workpiece, during support, first according to the shape of large-scale workpiece, the parameters such as center of gravity, bottom it, multiple position connects backstay 9, then the position matched below each backstay 9 arranges housing 1, under original state, inner sleeve groove 6 in inner sleeve 5 is in the position matched with clamping balls 3, clamping balls 3 is positioned at inner sleeve groove 6, the movement locus of the ball 8 that is locked below three clamping balls 3 and backstay 9 is not interfered, therefore the ball 8 that is locked can enter into spherical groove smoothly, then motor 7 drives worm screw to rotate, worm gear 4 and inner sleeve 5 is driven to rotate relative to ball seat 2, all clamping balls 3 all can roll out from inner sleeve groove 6, simultaneously to backstay 9 the motion of direction, axis and with the exterior surface of the ball 8 that is locked, the ball 8 that is now locked can rotate freely in spherical groove, but the height of its centre of sphere cannot rise due to the restriction of clamping balls 3, achieve the locking of ball 8 on Z axis is put that be locked, when installing multiple housing 1, the centre of sphere of the spherical groove ensured in all housings 1 is needed to be on same level height, but because spherical groove is positioned at housing 1 inside, cannot directly measure, therefore on all housings 1, fixed position place is all provided with target ball 10, when installing, only need to ensure that the centre of sphere of all target balls 10 can ensure that on same level height the centre of sphere of all spherical grooves is also on same level height, because the ball 8 that is locked below backstay 9 can freely rotate, therefore each backstay 9 can both make accommodation according to the stressing conditions of self within the specific limits automatically, to ensure the excellent support to large-scale workpiece, prevent large-scale workpiece itself from meeting with stresses.
