Abstract
The utility model provides a cross arm rotation axis structure of a digital X-ray camera, comprising a rotation axis component and a vertical column, wherein the rotation axis component is mounted on the vertical column and coordinated with a motor gear; the rotation axis component comprises a split rotation axis, a central gear and a bearing; the rotation axis and the central gear are fastened as an integer through a screw, and then mounted on a lifting trolley of the vertical column; then a conical bearing, a sleeve, a conical bearing and double nuts are mounted in order; a main difference between the cross arm rotation axis structure of digital X-ray camera and the prior art is the rotation axis component; the cross arm rotation axis structure of digital X-ray camera mainly uses the rotation axis, the central gear and the bearing which are combined into a structure, and the prior art only uses a gear bearing. The cross arm rotation axis structure of digital X-ray camera mainly comprises the rotation axis, the central gear and the bearing to avoid said condition, so that the process is simple, the cost is low, the delivery time is short and the use is reliable.
Description
Technical field
This utility model provides a kind of transverse arm revolute axes configuration of digital X-ray camera.
Background technology
U type, UC type arm digital X-ray camera chain all require transverse arm to pivot, so that satisfy a plurality of position photography requirements, the structural requirement of this rotating shaft is simple and reliable.
For satisfying a plurality of position photography requirements, require transverse arm 1 to rotate around rotating shaft assembly 2, rotation angle range :-30 °-120 ° (with top viewstate is 0 °, clockwise turns to negative), and require arbitrarily angled can stop of transverse arm 1 in limited range.The implementation that transverse arm 1 rotatablely moves: move (central gear is the part of rotating shaft assembly 2) at central gear by the motor-driven planetary gear, thereby allow transverse arm 1 rotation, and rely on the performance of motor self-locking, can realize location and lock function.
At present at home and abroad in the product, the implementation that transverse arm rotatablely moves: on gear-bearing, move (gear-bearing is made up of gear and bearing) by the motor-driven planetary gear, thereby allow the transverse arm rotation, and rely on the performance of motor self-locking, can realize location and lock function.
Gear-bearing is actually gear and bearing is processed into a part, and its difficulty of processing is big, the cost height, and the friendship phase is longer.
The utility model content
This utility model provides a kind of transverse arm revolute axes configuration of digital X-ray camera, the composition structure of its rotating shaft assembly, and part processing is simple, and cost is low.
This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of transverse arm revolute axes configuration of digital X-ray camera, it comprises rotating shaft assembly and column, described rotating shaft assembly is installed on the described column, described rotating shaft assembly cooperates with motor gear, it is characterized in that: described rotating shaft assembly comprises rotating shaft, central gear and the bearing of split, described rotating shaft and described central gear are tightened to one by screw, attach it to again on the lift cart of described column, next conical bearing, sleeve, conical bearing and double nut are installed successively.
Difference between the two is mainly at rotating shaft assembly, a kind of structure that this utility model mainly uses rotating shaft, central gear, three kinds of parts of bearing to be combined into, and the latter has used a kind of part of gear-bearing.
This utility model can be avoided above-mentioned situation, mainly uses rotating shaft, central gear, three kinds of parts of bearing, makes processing simple, and cost is low, and the friendship phase is short, uses same reliable.
Description of drawings
Fig. 1 is existing UC type arm digital X-ray camera chain structure chart;
Fig. 2 is this utility model example structure sketch map;
Fig. 3 is this utility model embodiment partial enlarged drawing;
Fig. 4 is this utility model example structure explosive view.
Wherein: 1-transverse arm, 2-rotating shaft assembly, 3-column, 4-rotating shaft assembly, 6-nut, 7-conical bearing, 8-screw II, 9-rotating shaft, 10-screw III, 11-sleeve, 12-central gear, 13-lift cart.
The specific embodiment
With embodiment this utility model is described in further detail with reference to the accompanying drawings below:
A kind of transverse arm revolute axes configuration of digital X-ray camera, it comprises rotating shaft assembly 2 and column 3, described rotating shaft assembly 2 is installed on the described column 3, described rotating shaft assembly 2 cooperates with motor gear, it is characterized in that: described rotating shaft assembly 2 comprises rotating shaft 9, central gear 12 and the bearing of split, described rotating shaft and described central gear are tightened to one by screw, attach it to again on the lift cart of described column, next conical bearing, sleeve, conical bearing and double nut are installed successively.
The structure that transverse arm 1 is installed to column 3 by rotating shaft assembly 4 as shown in the figure.
Figure below is the partial enlarged drawing of last figure, and after transverse arm inserted rotating shaft assembly 2, the screw I4 that screws on all around was fixed together transverse arm and rotating shaft, makes transverse arm to rotate, and can not do horizontal movement.
The structure that rotating shaft assembly 4 is installed to column 3 as shown in the figure.Earlier rotating shaft 9 and central gear 12 are mounted to an assembly, then use screw II 8 that this assembly is installed on the lift cart 13, next conical bearing 7-sleeve 11-conical bearing 7-double nut 6 is installed successively by screw III 10.
Difference between the two is mainly at rotating shaft assembly, a kind of structure that this utility model mainly uses rotating shaft, central gear, three kinds of parts of bearing to be combined into, and the latter has used a kind of part of gear-bearing.
This utility model can be avoided above-mentioned situation, mainly uses rotating shaft, central gear, three kinds of parts of bearing, makes processing simple, and cost is low, and the friendship phase is short, uses same reliable.
Those skilled in the art do not break away from essence of the present utility model and spirit, can there be the various deformation scheme to realize this utility model, the above only is the preferable feasible embodiment of this utility model, be not so limit to interest field of the present utility model, the equivalent structure that all utilization this utility model description and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
