Abstract
The utility model relates to a fixing device convenient for adjusting a guide rail shaft. The fixing device comprises two guide rail shaft seats extending longitudinally, wherein a transverse through hole is arranged in the upper part of each guide rail shaft seat, and the end parts of the guide rail shaft are inserted into the through holes. The fixing device is characterized in that multiple parallel annular arc-shaped inward bulges are arrayed along the axial direction to form the inner wall of each through hole, or multiple parallel strip-type arc-shaped inward bulges are arrayed along the periphery of the section to form the inner wall of each through hole; the fixing device also comprises hollow cylindrical positioning devices transversely arranged at the outer ends of the guide rail shaft seats, a pair of strip-type openings are arranged in the side walls of the positioning devices, the connection line of the positions of the two strip-type openings is along the radial direction of the section of the positioning device, and screws passing through the two strip-type openings are arranged on the positioning device. According to the fixing device, the inner wall of each guide rail shaft seat is designed into a structure that multiple arc-shaped inward bulges are arrayed, and the contact area of the guide rail shaft and the through hole inner walls of the guide rail shaft seats is reduced, so that the adjustment on the guide rail shaft becomes convenient and labor-saving.
Description
Technical field
The utility model relates to a kind of fixture of textile machine parts, relates in particular to a kind of fixture of air-jet loom lead rail axis.
Background technology
Heald frame mainly plays driving the effect that heald forms opening as one of significant components of air-jet loom, adopts aluminium matter alloy to make more.For guaranteeing that laterally braiding is even, smooth, integraty is good, usually needs regularly to adjust the heald frame lateral attitude by lead rail axis and realizes.But because the space between lead rail axis two ends and place lead rail axis block hole inwall is less, cause mobile difficultly because of reasons such as corrosions easily, directly knock vertically lead rail axis when coming adjusting position with hammer, very painstaking.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to adjust, laborsaving, the lead rail axis fixture of positioning stablity.
For achieving the above object, the technical solution adopted in the utility model is: a kind of convenient fixture of regulating lead rail axis, the guide rail axle bed that comprises two longitudinal extensions, the top of described guide rail axle bed is provided with cross through hole, described lead rail axis end is plugged in the described through hole, it is characterized in that: the inwall of described through hole is arranged vertically by a plurality of parallel ring-type arc convexes and is formed, perhaps formed by cross section, convex edge circumferential array in a plurality of parallel strip arcs, described fixture also comprises the hollow tube-shape locator that crosses at described guide rail axle bed outer end, described locator sidewall has the strip gab that a pair of difference is extended vertically, the position line of described two strip gabs is along the locator cross-section radial, and described locator is provided with the screw that passes described two strip gabs.
In preferred embodiment of the utility model, comprise that further described locator internal diameter equals described lead rail axis diameter.
In preferred embodiment of the utility model, further comprise described locator internal diameter greater than described lead rail axis diameter, and the inwall bottom flushes with described lead rail axis bottom height.
In preferred embodiment of the utility model, the inwall that further comprises described locator is also arranged vertically by a plurality of parallel ring-type arc convexes and is formed, and is perhaps formed by cross section, convex edge circumferential array in a plurality of parallel strip arcs.
In preferred embodiment of the utility model, the axial length that further comprises described locator is 2-4 times of lead rail axis block hole length.
In preferred embodiment of the utility model, comprise that further a described strip gab is positioned at the bottom of described locator, another strip gab is positioned at the top of described locator.
The utility model has solved the defective that exists in the background technology, the fixture of convenient adjusting lead rail axis of the present utility model is designed to the structure that a plurality of arc convexes arrangements form with the inwall of guide rail axle bed, reduced the contact area of lead rail axis and lead rail axis block hole inwall, probability and area that corrosion occurs have fundamentally been reduced between the two, weakened and caused lead rail axis to move the factor of difficulty, reduced simultaneously frictional resistance, so that the convenience that the adjusting of lead rail axis becomes is laborsaving.Locator has increased the lateral separation of back guide axle on the one hand, so that the length of lead rail axis block hole can reduce, to reach the purpose that further reduces with lead rail axis Contact area, on the other hand by the location of screw realization to the lead rail axis position, keep the lateral stability of lead rail axis.The internal diameter of locator can be set greater than the lead rail axis diameter, only with locator base plate back guide axle, reduce unnecessary contacting between locating shaft and lead rail axis, help equally more easily rail plate axle.

The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Embodiment 1, and as shown in Figure 1, a kind of convenient fixture of regulating lead rail axis comprises the guide rail axle bed 2 of two longitudinal extensions, and crosses at respectively two hollow tube-shape locators 4 of two guide rail axle bed 2 outer ends.The top of two guide rail axle beds 2 is respectively equipped with cross through hole 6, and the end of heald frame 1 two ends lead rail axis 3 is plugged in respectively in the through hole of two guide rail axle beds 2.The inwall of the inwall of through hole 6 and locator 4 by a plurality of identical circular arc convexes 8 parallel to each other vertically close-packed arrays form, locator 4 internal diameters equal the diameter of lead rail axis 3.Locator 4 sidewalls have the strip gab that a pair of difference is extended vertically, strip gab 12 is positioned at the bottom of locator 4, another strip gab 14 is positioned at the top of locator 4, the position line of two strip gabs is along locator 4 cross-section radials, locator 4 is provided with the screw 16 that passes described two strip gabs, the head of screw 16 is positioned at strip gab 14 outsides, and afterbody passes strip gab 16, and is fixing with nut 18.Locator 4 itself is threaded connection and is fixed in guide rail axle bed 2, the axial length of locator 4 be guide rail axle bed 2 through holes 6 length 2-4 doubly, have guide rail axle bed 2 back guide axles 3 most of weight than the through hole 6 of short axial length with cooperation, guarantee stability.
