Abstract
The utility model discloses an automatic compensating device for a C-type arm gap of a medical mobile X-ray unit, and belongs to the technical field of medical instruments. The automatic compensating device for the C-type arm gap of the medical mobile X-ray unit is structurally composed of a C-type arm support (1), a guide wheel support (2), a lateral automatic compensating spring (3), a lateral fixed guide wheel assembly (4), an axial floating guide wheel shaft (5), an axial floating guide wheel assembly (6), a C-type arm (7), a lateral floating guide wheel assembly (8), an axial fixed guide wheel assembly (9), an axial automatic compensation spring (10), a spring base (11) and a spring press plate (12). The automatic compensating device for the C-type arm gap of the medical mobile X-ray unit is characterized in that when the C-type arm (7) moves in an automatic compensating guide rail, a guide wheel of the automatic compensating guide rail makes contact with the rail of the C-type arm (7) all the time as long as the size of the cross section of the rail of the C-type arm (7) changes within a certain tolerance range, and therefore the C-type arm (7) can slide steadily along the automatic compensating guide rail. The automatic compensating device has the advantages of being compact in structure, light in weight, convenient to install and low in cost.
Description
Technical field
The invention belongs to technical field of medical instruments.
Background technology
Existing mobile X-ray unit C type arm is along rail sliding device conventionally in the following ways: the rail-sides of C type arm to guide wheel be radially all fixing uncontrollable, in the time that the rail section dimensional tolerance of C type arm is overproof, sectional dimension is less than lower deviation, the track of C type arm is stuck owing to coordinating tension with the guide rail of C type arm, sectional dimension is greater than the upper deviation, the guide rail of the track of C type arm and C type arm is owing to coordinating pine to occur to swing or shake, the kinematic accuracy of equipment is reduced greatly, even cannot work; Secondly, due to too high to the rail section size tolerance requirements of C type arm, so cause processing technique complexity, high cost; In addition, owing to having certain gap between the track of C type arm and guide rail, when C type arm does 180 ° while waiting centre scan, C type arm can produce end face run-out and circular runout, makes the centre scan precision such as C type arm not reach instructions for use.
Summary of the invention
The design's goal of the invention is: overcome the defect that above-mentioned C type arm brings along rail sliding device, utilize guide rail to come the gap between track and the guide rail of the C type arm that auto-compensation brings because of the rail section scale error of C type arm at side direction and axial auto-compensation guide wheel, in the time that C type arm moves in auto-compensation guide rail, as long as when the rail section size of C type arm changes in certain margin of tolerance, the guide wheel of auto-compensation guide rail all contacts with the track of C type arm from start to finish, eliminate the gap between track and the guide rail of C type arm, make C type arm along auto-compensation guide rail smooth sliding, kinematic accuracy improves greatly.
The design invents and solves the technical scheme that adopts of its technical problem and be: its structure is by C type arm support, wheel bracket, side direction auto-compensation spring, side direction stator ring assembly, axial float guide wheel shaft, axial float guide wheel assembly, C type arm, the side direction guide wheel assembly that floats, axial restraint guide wheel assembly, axially auto-compensation spring, spring base, spring bearer plate composition, it is characterized in that: wheel bracket is fixed on C type arm support, one side assembling side direction stator ring assembly of wheel bracket, the unsteady guide wheel assembly of opposite side assembling side direction of wheel bracket, side direction auto-compensation spring assembling is in the inner of the unsteady guide wheel assembly of side direction, axial restraint guide wheel assembly is assemblied in the interstitial hole of wheel bracket, axial float guide wheel assembly is assemblied in the end hole of wheel bracket, spring base is assembled in the positive face of wheel bracket, below spring base, be pressed on axial float guide wheel shaft, above spring base, place axial auto-compensation spring, spring bearer plate compression axis is to auto-compensation spring, above parts composition auto-compensation guide rail, in the time that C type arm moves in auto-compensation guide rail, as long as when the rail section size of C type arm changes in certain margin of tolerance, the guide wheel of auto-compensation guide rail all contacts with the track of C type arm from start to finish, make C type arm along auto-compensation guide rail smooth sliding.
The design's beneficial effect of the invention is: mobile X-ray unit C type arm is along in slide process, require the motion of C type arm steadily, light, particularly in the centre scan processes such as C type arm, require end face run-out and the circular runout of C type arm to be all less than a pixel (0.2mm left and right), mobile X-ray unit installs additional after C type arm automatic compensator for clearance, in the time that C type arm moves in auto-compensation guide rail, because the guide wheel of auto-compensation guide rail all contacts with the track of C type arm from start to finish, eliminate the gap between track and the guide rail of C type arm, make C type arm along auto-compensation guide rail smooth sliding, the end face run-out and the circular runout that produce because of the gap between guide rail and track are thoroughly eliminated, greatly improve radioscopic image quality.This C type arm automatic compensator for clearance compact conformation, lightweight, easy for installation, low cost and other advantages, working effect is remarkable, safe and reliable.
