Abstract

The utility model discloses an adjustable shaft marking bracket, which is characterized in that the left end surface and the right end surface of a dovetail groove of a support platform (6) are both provided with two or more than two support wheel mounting grooves (11), support shafts (4) with supporting wheels are arranged in the support wheel mounting grooves (11), thereby enlarging the markingrange of shafts, and a jack (10) is further arranged on the lower surface of the support platform (6), which enables the lifting of large-sized shafts to be more convenient and labor-saving.

Description

Adjustable axle class line support

Technical field

The utility model relates to a kind of class line support, especially relates to a kind of adjustable axle class line support.

Background technology

At present, there are some defectives in the employed traditional axle class line of mechanical industry support, and is particularly heavy very inconvenient with the axle class line larger axis footpath.One, the dovetail groove left and right sides both ends of the surface of brace table in the past all only are provided with an installation groove respectively and are used for placing the back shaft that support wheel is installed, the position of the back shaft that support wheel is installed can not be adjusted according to diameter of axle size, the big axle class of some diameter of axle can not be rule on support.They are two years old, though traditional line support adopts mechanism's mode of the two guide pillars of two guide rails to guarantee the job stability of axle class line and the bad intensity of using of itself, but great axle class adjustment is being required great effort very much, adjust each time and all want the workman to be placed into to remove to rotate guide pin bushing inside the hole on the guide pin bushing that is installed in two guide pillars to adjust scribing position with lever, adjustment for the scribing position of the axle class of heavy type is very much an effort, utilize overhead traveling crane to adjust and do not reach precision, so not only increased working strength of workers, and precision does not reach yet.The utility model has designed a kind of adjustable axle class line support, has well remedied above defective.

The utility model content

The purpose of this utility model provides a kind of ratio line support that diameter of axle scope was bigger in the past, and a kind of more easily adjustable axle class line of scribing position adjustment support.

In order to achieve the above object, the utility model is to adopt the axle class line support of following structure to solve, the left and right sides both ends of the surface of brace table dovetail groove are provided with two or more support wheels groove are installed, be placed with the back shaft that is used to install support wheel in the groove, can come the axle class of the different diameters of axle is rule in the position that different support wheels are installed groove by changing support wheel.

Described brace table supported underneath has jack, and jack is installed in the blind hole of base bottom.Jack is general common jack, be arranged on brace table below, brace table is carried out lifting.

The beneficial effect of the utility model adjustable axle class line support is: being provided with of jack solved the artificial adjustment inconvenience when setting-out of heavy axle class, and the overhead traveling crane adjustment does not reach the problem of required precision again.Two or more support wheels are installed the line scope that being provided with of groove enlarged the axle class.Adjustable axle class line support after the improvement is rule a class, and scope is big, easy to adjust, use is simple, the efficient height.

Description of drawings

The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model pedestal (2);

Fig. 3 is the structural representation of the utility model brace table (6);

Fig. 4 is that the utility model brace table (6) is increased to the structural representation that three support wheels are installed groove;

1 is that base plate 2 is that pedestal 3 is that adjustment chamber 4 is that back shaft 5 is that support wheel 6 is that brace table 7 is that guide pin bushing 8 is that guide pillar 9 is that packing ring 10 is that jack 11 is back shaft grooves in the accompanying drawing

The specific embodiment

Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, pedestal 2 is installed on base plate 1, two through holes and a blind hole of pedestal 2 bottom surfaces are separately installed with two guide pillars 8 and jack 10, the head of two guide pillars 8 is installed in two installing hole the insides that brace table 6 is provided with, the left and right sides of brace table 6 is installed on two guide rails of both sides of pedestal 2, be convenient to moving of vertical direction, respectively be provided with two or more support wheels on the left and right sides both ends of the surface of the dovetail groove of brace table 6 groove 11 is installed, the back shaft 4 of being convenient to be equipped with support wheel changes the position according to the diameter of axle of part to be processed, makes a part rotation line more flexible.

Described pedestal 2 is approximately the U type, and the upper end cross section is the T type, adopts No. 45 steel.Pedestal 2 left and right sides are provided with two guide rails, and brace table 6 can move up and down on two guide rails, and the bottom surface is provided with two through holes and a blind hole, about two through holes are guide pillar 8 telescopic holes, middle blind hole is the bottom installing hole of jack 10.Respectively be provided with two or more support wheels on the left and right sides both ends of the surface of the dovetail groove of described brace table 6 groove 11 is installed, placed the back shaft 4 that support wheel is installed in support wheel is installed groove 11, the placement location that the back shaft 4 of support wheel is installed by change satisfies the axle class of the different diameters of axle and rules.Brace table 6 bottoms have two blind holes that some distances are arranged, and are used for installing the guide pillar head.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model in use, after the line support is kept steady, the back shaft 4 that support wheel will be installed according to the big or small selectivity of the diameter of axle of axle spare is placed on the proper supporting wheel installation groove 11, about respectively select one, the diameter of axle is less can select in the inner part installation groove for use, and the diameter of axle is bigger can select in the outer part installation groove for use, and putting needs the axle of line part.The dovetail groove of brace table can not become flexible above axle is placed at an angle of 90.Adjust the position by adjusting jack 10 with two guide pillars 8, after reaching desirable position, just can rule, if in the time of also need ruling in other position of bent axle, turning cylinder, the integral position of checking, adjust bent axle then begins line when meeting line and require, up to all draw good till.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
