Abstract

PURPOSE:To make it easily usable in a simple structure and optionally embeddable in an objective spot by constituting a roller support shaft so as to cause its one end to be projected from the side of a support main body and to serve as a locating pin. CONSTITUTION:At the time of application, a fixing shaft 25 is inserted into a fixing shaft insert hole 13 for a boss part 12 of a support main body 10, attaching it to a machine frame A or the like. At this time, a circular long hole (a) is preinstalled in the frame side in a radius ranging from the center of this fixing shaft 25 to the shaft center of a roller support shaft 15. At the time of installation, a projecting end 15' of this roller support shaft 15 is attached so as to be inserted into the long hole (a), and thereby a roller 20 is set so as to come into contact with an objective guide rail B. With such a position that a contact state between the roller 20 and the guide rail B comes to be smoothly operable, a nut 25' screwed in the fixing shaft 25 (mounting bolt) is clamped for fixation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to a guide roller unit that can be used in moving parts or guiding parts of various industrial machines to rationally assemble a guiding mechanism.

Background and Problems of the Invention In general, rollers are placed at locations where partial mechanisms in small equipment move, and the rollers are supported rotatably by pins attached to fixed positions. It is configured to do so. Therefore, the support pins and rollers must be individually housed and combined, and in order to ensure proper contact between the rollers and the guide bodies that come into contact with the rollers, it is necessary to The operation is cumbersome because either of the above must be performed by adjusting the movement.

Particularly, when it is necessary to attach a large number of rollers, it is a matter of course that each roller must be adjusted individually at the attachment portion, which is inconvenient as the adjustment requires a lot of effort. Furthermore, in relatively large-sized devices and equipment, when arranging guide rollers, a method of arranging support pins as described above is used. Therefore, the workability is not good, and furthermore, the combination thereof requires a lot of work, and since it is mainly fixedly attached, it is inconvenient to adjust it. Of course, since it is stored exclusively for use, it also has the disadvantage that it cannot be easily replaced. However, since there are few cases where mass production is possible due to the structure, it is inevitable that the unit manufacturing cost will be high and the labor cost will increase.

Means for Solving the Problems: The present invention solves these problems and provides a unit-type guide roller unit that has a simple configuration, is easy to use, and can be incorporated into any desired location depending on the application. It's about doing.

That is, the present invention has a boss portion provided with a mounting shaft insertion hole in the main body, and the mounting portion of the roller support shaft is installed at a parallel position appropriately spaced apart from the boss portion forming the mounting shaft insertion hole as a reference. A pair of support pieces are combined to form two support bodies; a roller is rotatably supported on a roller support shaft provided on the support body; It is constructed so that it protrudes from the side surface and can serve as a positioning pin at the attachment part.

Various structures can be formed as the supporting body of the present invention.

First, there is a structure in which a support piece is combined with a mounting shaft insertion hole-forming boss portion provided at one end and a roller support shaft disposed at a position a predetermined distance from the boss portion. The plate of this support piece can be selected to have an appropriate thickness depending on the load.

In addition, the mounting shaft insertion hole forming boss part may be formed as a body with respect to the plate (supporting part) forming the support main body, for example, a molded structure, a forged structure, or a combination of the plate and the boss. There are also those that are integrally molded, such as those that are made into one piece by welding. Alternatively, the support piece and the boss may be integrally assembled using a sleeve or hollow rivet, or assembled using a screw structure. These structures can be arbitrarily selected from small to large sizes. . Furthermore, the support main body can also be constructed by dividing the mounting shaft insertion hole forming boss portion at an intermediate position and combining the parts formed left and right symmetrically.

Regarding the outer shape of this supporting body, three arbitrary shapes can be used. The optimal shape may be selected depending on the conditions of the installation location.

Regarding the roller support shaft, at least one end thereof should have a length equivalent to the thickness of the mounting part of the aircraft body etc. to which the guide roller unit of the present invention is attached, and protrude from the side surface of the plate of the support main body, and the protruding end should be attached to the mounting part of the aircraft body side. The roller unit can be mounted in a predetermined position by fitting into a positioning hole provided corresponding to the mounting hole provided in the section.

Note that the mounting shaft may be attached in advance to the storage shaft insertion hole forming boss portion. Alternatively, a screw hole may be provided in the boss portion, and the structure may be such that it is attached by screwing with a bolt.

Various types of rollers can be employed as the rollers supported by the roller support shaft. Examples include rolling type rollers with balls, rollers with multiple rollers built in, solid rollers made of synthetic resin, rollers made of oil-impregnated sintered alloy, and composite rollers made of a combination of these. .

If one of these rollers is of a composite type with thrust bearing pieces made of oil-impregnated sintered alloy incorporated in the side, it can be used without difficulty even under thrust loads. . Of course, if a lubricating structure is incorporated, durability can be increased. Alternatively, if a small ball bearing is incorporated into engineering plastic, the roller will be able to withstand thrust loads sufficiently. This type of roller has relatively large dimensions (but is not particularly limited) and is effective when used under heavy loads.

Moreover, as for the outer shape, any shape can be adopted, such as one with an arcuate groove on the outer circumferential surface, one with a square groove, one with a flat surface, and one with a protrusion.

Regarding the roller support shaft mentioned above, it is made eccentric and has a structure in which the rotation of the shaft can be adjusted from the outside.
Instead of adjusting the contact state between the roller and the guide by displacing the axial center position of the roller support shaft with respect to the shaft inserted into the mounting shaft insertion hole forming boss part, the eccentric shaft is rotated to adjust it. You can do it like this. This also applies to the mounting shaft.

Regarding the state in which the rollers are stored, a boss may be provided on the roller support part that is the main support, and the rollers may be supported from both sides by the support shafts.If necessary, the roller support shafts may be The guide roller can be configured to be supported at a position parallel to the mounting axis with a required angular displacement. In this method, a mounting method is adopted in which a plurality of guiding rollers are equally divided around the guide shaft and arranged around the guide shaft.

It is also possible to attach a non-rotating slider to the roller support shaft 9 In this case, it is used as a slide guide piece 6 Function: The guide roller unit of the present invention can be used, for example, for movement in automatic machines, etc. When used as a guide for a body, if a reference mounting hole and an insertion hole for the roller support bearing are previously drilled in the machine frame at the desired position, the shaft insertion hole forming boss section is attached to the mounting hole. Insertion shaft (or pole l-)
, and install the unit using this as a reference. First, insert the tip of the roller support shaft into the support shaft hole so that the guide roller properly contacts the rail, etc. that will serve as a guide. Temporary settings can be easily made. Therefore, if the relationship between the guide roller and the rail is correct, just fix the mounting shaft to the frame as is, but if the contact is not sufficient, rotate the eccentric mounting shaft or the roller support shaft to connect the guide roller and the rail. Adjust so that the contact is correct. Alternatively, if the roller support shaft hole is a long hole, by moving the protruding end of the roller support shaft with reference to the mounting shaft and rotating the support body three times, the contact between the guide roller and the rail can be made correctly. Can be set.

Alternatively, after temporary attachment, the roller support shaft or the attachment shaft (attachment bolt) is rotated and the adjustment operation is performed using the first center of the shaft, thereby making it possible to easily make fine adjustments.

Once this adjustment is completed, dimensional errors in the machining process can be easily corrected by tightening and fixing the mounting shaft.

Moreover, if this roller unit is adopted, a guide mechanism can be easily configured by providing a predetermined hole in the frame and attaching the hole.

Embodiment: The guide roller unit of the present invention will be described below based on embodiment drawings.

The one shown in FIGS. 1 to 3 is the most typical configuration, in which the support main body 10 consists of two support pieces 11.
and one boss 12 for forming an attachment shaft insertion hole, and the boss 12 and the support piece 11 are integrally formed. A mounting shaft insertion hole 13 is bored in the boss 12 portion, and this hole 13 serves as a reference during installation. A roller support shaft hole 14 is bored in the distal end of the support main body 10 in parallel with the attachment shaft insertion hole 13. A roller support shaft 15 is fitted into the support shaft hole 14 with one end protruding outward, and a roller 20 is rotatably provided between both support pieces 11 by the roller support shaft 15.

The attachment relationship between the support piece 11 of the support main body 10 and the boss 12 is determined at the time of assembly (
In order to make the work easier, for example, a fitting structure is adopted and a friction fixing type is adopted. Alternatively, the two support pieces 11 and the boss 12 may be integrally formed using the sleeve 18 by caulking both ends of the sleeve 18.

The roller support shaft 15 is supported at both ends in support shaft holes 14 that are bored in the support piece 11, and the axis of the roller support portion is aligned with the support portion by an appropriate amount (formed by centering). Then, one end of the support piece 11 is protruded outward to form a protruding end of 15°, and a rotation notch 16 is provided on the side that does not protrude from the outer surface of the support piece 11 for a long time. The state of contact between the rollers and the guide rail can be set at .

Regarding the cut 16 of the support shaft 15, if the shaft has a small diameter, a single cut as shown in the figure may be sufficient, but if the shaft has a large diameter, a rectangular bottomed hole may be provided. In this way, the rotation can be adjusted using a wrench, which is convenient.

Various rollers can be used as the roller 20. The most common type is one with internal ball bearings, and the roller body is made of, for example, synthetic resin or resin with high mechanical strength, such as nylon. The shape of the outer periphery can be arbitrarily set depending on the purpose, such as a flat shape, a concave curved surface (arc groove), a V-shaped groove, or a flanged shape. In the axial direction, there is a slot between the inner surface of the support piece 11 and the outer surface of the roller 20.
- By interposing the plate 17 in the support, the roller can rotate without any problem even if it receives a load in the axial direction.

In addition to the above-mentioned combination of bearing and main body, there are also needle bearings whose outer ring is used as a roller, ball bearings that are used as rollers, those made from a single synthetic resin, and oil-impregnated sintered alloys. or the like can be arbitrarily adopted depending on the purpose.

The guide roller unit has the configuration described above.

In use, for example, as shown in FIGS. 4 and 5,
The attachment shaft 25 is inserted into the attachment shaft insertion hole 13 of the boss portion 12 of the support main body 10 so as to be attached to the frame A of the machine or the like. At this time, an arcuate long hole a° is previously provided on the frame side with a radius from the center of the attachment shaft 25 to the axis of the roller support shaft 15.

At the time of installation, the protruding end 15'' of the roller support shaft 15
The roller 20 is installed so as to be inserted into the elongated hole a, and set so that the roller 20 comes into contact with the target guide rail B.

The nut 25 screwed onto the mounting shaft 25 (mounting pole l-) is tightened and fixed in a posture such that the contact state between the roller 20 and the guide rail B can operate smoothly.

In this way, the moving part of the machine (frame A) with the rollers 20 along the guide rail B is facilitated to be guided and moved. Or, conversely, the guide rail B (the guiding shaft) becomes easier to move.

In addition to the above-mentioned types of units, see Figure 6 (
aHb), the supporting body 108 is attached to the boss portion 12.
It is also possible to form a structure in which the hollow sleeve 18 is inserted into the mounting shaft insertion hole 13a by symmetrically arranging the two parts a, which are integrally molded, and are fixed by expanding them at both ends and caulking them together. .

Alternatively, as shown in FIG.
At one end of the flanged attachment shaft 26 fitted into the support piece 1
1b is caulked and fixed in the seat hole 13b', and is integrated with this mounting shaft 26, and the mounting shaft 2
It is also possible to use a screw shaft 26' at the bent end of 6 so that it can be fastened with a nut when attached to a frame or the like. Note that in this specific example, two rollers 20 are arranged side by side on the roller support shaft 15b, but of course it can be formed in the same way even if there is only one roller 20. In this case, the roller support shaft 15b can also be adjusted by the contact state between the roller and the guide rail in the same manner as in the above case by making it a rotary center shaft.

For any of the above-mentioned types, they can be attached to the frame of the equipment as described above, but as for how to attach them,
Various combinations can be considered as necessary, and these can be arbitrarily set according to the conditions.

When using the above-mentioned guide roller unit, as shown in FIG. 8, for example, as shown in FIG. touches the guide surface. In this case, when the protruding end 15' of the roller support shaft 15 is inserted into a positioning hole pre-drilled in the machine body, the eccentric shaft can be rotated by a notch 16 provided at the opposite end. Thus, the contact state between the roller 20 and the guide surface can be adjusted to an optimal state. Alternatively, as shown in FIG. 9, the guide roller unit IOA can be attached to the machine body A, the rollers 20 can be brought into contact with the guide rail B, and either the machine body A or the guide rail B can be moved. In both of these, the protruding end 15° of the roller support shaft 15 is engaged with a hole provided in the body (frame), the support main body 10 or IOA is fixed, and the steel core of the support shaft is used to make contact. This shows how adjustments can be made.

As shown in FIG. 10, long holes a and a' for attachment are drilled in the frame A of the machine, and the protruding ends of the attachment shaft and roller support shaft are inserted into each of them to attach the roller 20. When contacting the guide body B, the guide roller unit 10 can be moved up and down (not necessarily moved up and down, but relative to the guide surface) along the long hole, and the nut is tightened and fixed in the optimal state. A method like this can be adopted. Of course, the method of use is not limited to those described above, and any combination of these methods can be used by attaching and using an optimal method.

As shown in FIG. 11, the mounting shaft insertion boss portion 12c of the support main body 10C is slightly different from the above-mentioned type.
Make the shaft insertion hole 13C into a screw hole to attach the frame A of the machine, etc.
When attaching to a vehicle, etc., the bolt 27 may be screwed in for attachment.The other structural parts are the same as those described above.

In addition, the roller and guide rail (guide surface) during installation
When adjusting the contact condition, do not fully tighten the mounting shaft.
After adjusting and setting the eccentricity of the roller support shaft properly, the mounting shaft portion is fully tightened, thereby positioning the roller under a predetermined condition.

Next, FIGS. 12 and 13 show another type of roller unit, in which the support main body 30 has a mounting shaft insertion boss 32 in the center, and link-shaped support parts on both sides. Two pieces 31 are arranged.

The support piece 31 and the boss 32 are integrally fastened together using a hollow rivet or a thin sleeve, or screwed together using a screw or the like. Of course, it can also be welded.

With reference to the mounting shaft insertion hole 33 provided in the boss portion 32, shaft holes are provided at both ends of the support piece 31, and the roller support shafts 35 inserted into these holes allow the rollers 20 to
is rotatably supported between both supporting pieces. Even in this state, the roller support shafts 35 are mounted with one or both ends protruding from the outer surface of the support piece. Regarding the roller 20 to be used, one having an external shape depending on the application can be selected and adopted, similar to the above-mentioned types.

In use, the mounting shaft is inserted into the mounting shaft insertion hole 33 or a bolt is inserted to attach it to a frame or the like. The protruding end 3 of the roller support shaft 35 is inserted into the positioning hole provided on the frame side in the same manner as in the above specific example.
5° and insert roller 2 into the guide rail (not shown).
Bring 0 into contact. At this time, it is possible to contact two guide rails at the same time. By making the hole into which the protruding end of the roller support shaft is inserted into a long hole, the contact state between the roller 20 and the guide rail can be conveniently adjusted by rotating the support body 31 with reference to the mounting shaft. It is. Of course, after setting, it is necessary to fix rotation on the mounting shaft. In addition, in this type of guide roller unit 30, it is not necessary to use the roller 21 [1 as is, but instead use the protruding end of the support shaft of one roller as a means for fixing the guide. 6. It can be used without restricting the positioning of the support shaft end on the roller side that contacts the rail. In addition, any other use is possible as required.

FIG. 14 and FIG. 15 show a further embodiment of the pond, and this type of guide rail unit 1- is constructed by combining a pair of molded support bodies 40, and is similar to the above-described one. Unlike the above, a roller support shaft insertion hole 14 is provided in the center, the roller 20 is supported by a support shaft 45 inserted therein, and mounting shaft insertion holes 43 are provided at both ends with reference to this roller position. It was established. This support main body 40 is integrally fastened with a hollow one-piece l-48 at each housing (+ shaft insertion hole 43 forming boss portion 42).The roller 20 used is the same as described above. The diameter of the 60-shaft 20 used is naturally larger than the height of the support body 41.

When using the housing 11, although this is also optional, it can be easily positioned using both storage shaft insertion holes 43 as references. Moreover, if one mounting shaft is used as a reference, reliable mounting can be achieved by setting the contact state between the roller and the guide surface and then inserting a bolt or the like into the other mounting shaft insertion hole to fix it. Preferably, the protruding end 45' of the roller support shaft 45 is inserted into the support hole so that it becomes stable. In this type as well, the roller support shaft can be made to have an eccentric structure in the same manner as in the above embodiment.

As described above, in the present invention, various types of RANO can be proposed, and they can not only be selectively adopted depending on the application, but also partially changed to correspond to the corresponding use. It can be the most appropriate one for the conditions. Therefore, it goes without saying that partial improvements are also included in the present invention.

Effects of the Invention: According to the present invention, the guide mechanism of not only small devices but also large machines, in which rollers and the like were previously made and assembled individually, has been made into a unit type. For example, it can be used in the same way as Units l-bearings, and since it does not require complicated machining, it is easy to install, easy to adjust, and has excellent workability. By choosing a material that has corrosion resistance, it is useful as a guide mechanism in water. Moreover, since it has a configuration that allows for mass production, it can be provided at low cost and can be said to be useful as a highly versatile guide unit.
