Description
Technical field
The utility model relates to a kind of supporting construction, particularly a kind of trapezoidal thread 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 utility model 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 trapezoidal thread electric lock ball chuck compact schemes structure of adaptive adjustment while clamping, support workpiece as required.
Technical solution of the present utility model is: a kind of trapezoidal thread electric lock ball chuck compact schemes structure, comprise cylindric housing 1, it is characterized in that: be fixedly installed ball seat 2 on the top of housing 1, be spherical groove in ball seat 2, at least two are embedded with in circumferentially equally distributed clamping balls 3 at the sidewall of ball seat 2, being socketed with outside ball seat 2 can the piston 4 of lengthwise movement, piston 4 offers the clamping recess 5 matched with clamping balls 3, the bottom of piston 4 is connected with the pallet 6 being positioned at housing 1, pallet 6 is evenly distributed with at least two pin-and-holes, the axis of guide is provided with in pin-and-hole, the bottom of pallet 6 is provided with external thread column 7, external thread column 7 with female hollow shaft 8 be set be threaded, the motor 9 that hollow shaft 8 rotating support is being positioned at bottom housing 1, what match with spherical groove is provided with the ball 10 that is locked, backstay 11 is also connected with on the top of the ball 10 that is locked.
Described housing 1 is also provided with target ball 12.
Described target ball 12 is multiple, and is uniformly distributed on housing 1.
Compared with the existing technology, tool has the following advantages the utility model:
The trapezoidal thread 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.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model embodiment.
Fig. 2 is the outside drawing of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As Fig. 1, shown in Fig. 2: a kind of trapezoidal thread electric lock ball chuck compact schemes structure, comprise the housing 1 of the cylindrical shape based on, ball seat 2 is fixedly installed on the top of housing 1, be spherical groove in this ball seat 2, at least two are embedded with in circumferentially equally distributed clamping balls 3 in the sidewall of ball seat 2, can the piston 4 of lengthwise movement outer being then socketed with of ball seat 2, piston 4 offers the clamping recess 5 matched with clamping balls 3, the bottom of piston 4 is connected with pallet 6, it is inner that pallet 6 is then positioned at housing 1, pallet 6 is evenly distributed with at least two pin-and-holes, and in pin-and-hole, be also provided with the axis of guide, the bottom of pallet 6 is provided with external thread column 7, this external thread column 7 is threaded with arranging between female hollow shaft 8, hollow shaft 8 is the motor 9 that is being positioned at bottom housing 1 of rotating support then, what match with described spherical groove is also provided with the ball 10 that is locked, the top of this ball 10 that is locked also is fixedly connected with backstay 11, the supporting construction of this kind of version is conveniently installed, housing 1 is also provided with multiple at circumferentially equally distributed target ball 12.
The course of work of the trapezoidal thread electric lock ball chuck compact schemes structure of the utility model embodiment 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 11, then the position matched below each backstay 9 arranges housing 1, under original state, under clamping balls 3 on ball seat 2 sidewall is in the state matched with clamping recess 5, namely clamping balls 3 is positioned at clamping recess 5, the movement locus of the ball 10 that is locked now below circumferentially equally distributed multiple clamping balls and backstay 11 is not interfered, therefore the ball 8 that is locked can drop in spherical groove smoothly, then starter motor, hollow shaft 8 is driven to rotate, owing to being threaded connection between hollow shaft 8 and the external thread column 7 of pallet 6 bottom, and pallet 6 cannot rotate under the effect of the axis of guide, therefore the moment of torsion of hollow shaft 8 exports the lengthwise movement that just can change into pallet 6 and piston 4, when piston 4 lengthwise movement, clamping balls 3 will be forced to roll out from clamping recess 5, because clamping balls 3 cannot be moved in the vertical, therefore all clamping balls 3 will simultaneously to axial direction motion in backstay 11 and with the exterior surface of the ball 10 that is locked, the ball 10 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 ball 8 locking in the Z-axis direction that is locked, because the ball 10 that is locked below backstay 11 can freely rotate, therefore each backstay 11 can both make accommodation according to the stressing conditions of self within the specific limits, to ensure the excellent support to large-scale workpiece, prevent large-scale workpiece itself from meeting with stresses, when installing multiple housing 1, the centre of sphere of the spherical groove ensured on all ball seats 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 12, when installing, only need to ensure that the centre of sphere of all target balls 12 can ensure that on same level height the centre of sphere of all spherical grooves is also on same level height.
