l-leretofore, in order to facilitate the construction of cylinders in a variety of dilferent lengths in accordance with customer requirements, and in order to eliminate the need for an inventory of cylinders in a variety of lengths in anticipation of customer requirements, it has been customary to cut the cylinder body to the desired length from a preconstructed extra long cylinder body, and thereafter attach independently constructed cylinder heads to the opposite ends of the cut cylinder body by means of tie rods interconnecting the heads externally of and independently of the cylinder body.
it is an object of the present invention to provide a new and novel cylinder body construction adding longitudinal strength and rigidity to'the cylinder for minimizing'lateral bending of the cylinder body, and, at the same time, utilize the new cylinder body construction in a new and novel method of manufacturing a cylinder device to facilitate the cutting of cylinder bodies to length from an extra long cylinder body with the subsequent attachment of cylinder heads directly to the ends thereof by means of standard uniform length screws, thus eliminating the need for maintaining an inventory of more expensive tie rods of varying lengths.
In the present invention, this object is achieved by constructing in extra long length a cylinder body having integral therewith and externally disposed thereon a plurality of spaced ribs longitudinally extending along the full length of the body providing longitudinal and lateral rigidity. When the extra long cylinder body is transversely cut to the desired length, the end faces of the ribs are provided with tapped holes for receiving screws by which the cylinder heads are attached to the end faces of the cut cylinder body.
This and other objects will become more readily apparent in the following detailed description, taken in conjunction with I the drawing, in which:
Flt l is an exploded sectional view, taken substantially along the lines ll-l of HG. 2, of a fluid operated cylinder device showing my invention;
FIG. 2 is a sectional view of the cylinder body taken substantially along the line 2-2 of FlG. l; and
FlG-El is an end elevational view of the cylinder device of Flt l.
Referring now to the drawing, there is shown a partially assembled tluid operated cylinder device generally indicated at l and comprising a cylinder body 2, a piston assembly 3 attached to a piston rod 4 and reciprocable disposed in the cylinder body, a pair of cylinder heads 5 and s disposed adjacent opposite ends of the cylinder body, and a plurality of screws 7 attaching the cylinder heads to the cylinder body 2.
in accordance with the present invention, the cylinder body 2 is composed of any suitable metal and may be formed in any suitable manner, as by casting or extrusion where applicable, so as to provide a hollow cylindrical member having externally disposed thereon and integrally formed therewith one or more ribs 8 longitudinally extending the full length of the cylinder body, the ribs ll providing strength and rigidity to the cylinder body to minimize cylinder body sag, and, at the same time, providing novel means, by way of the rib end faces 9, to attach cylinder heads to the cylinder body and thus eliminate the need for the tie rods heretofore utilized in such attachment. The ribs 8 may be solid or may include through passages it), as desired. if the ribs 8 are solid, the end faces 9 of the ribs b are drilled and tapped at ll to receive the abovernentioned screws 7, thereby attaching the corresponding cylinder heads 5 and d to the cylinder body, in a manner hereinafter described. if the ribs contain through passages Ed, the ends of the through passages terminating at the end faces 9 of the ribs provide holes which may be tapped thus eliminating the drilling operation.
The piston assembly 3 and the associated pistonrod do not comprise part of the present invention, and accordingly, they may be of any suitable type.
The cylinder head 5 is generally rectangular in form and includes a combined supply and exhaust port 32 internally communicating with a cavity l3 opening at end face M, the latter communicating with the interior of the cylinder body 2 to supply fluid pressure to or exhaust fluid pressure from the cylinder body, depending upon whether the port 112 is being utilized as a supply or exhaust port. A passage l5, carrying a bearing it is provided through the head 5 coaxially with the cavity 13 to reciprocably receive therethrough the piston rod 4 in the manner shown in FIG. l. A plurality of through passages 17 are located at the comers of the head for axial alignment thereof with respect to the tapped ends 11 of the passages 10 when the head 5 is abutted with the end of cylinder body 2. One of the screws 7 is inserted in each of the through bores 17 and received in tapped ends ll of passages ill to tightly hold the cylinder head 5 in sealed engagement with the end of cylinder body 2.
if desired, suitable conventional cushioning means, not shown, may be provided to cushion movement of the cylinder as it nears the ends of its stroke.
Also in accordance with the invention, the ribbed cylinder body facilitates a new method of making and assembling a cylinder device by cutting to length the desired cylinder body from an extra long ribbed cylinder, drilling and tapping the end faces of the ribs, and attaching the heads to the ends of the cylinder body by screws received in the rib taps ll, thus eliminating the need for tie rods.
Specifically, the cylinder body is formed by casting or extrusion or in any other suitable manner, as a long cylinder body having ribs externally disposed thereon and formed integral therewith, which ribs extend the full length of the long cylinder body. When a cylinder is desired having a length less than the aforementioned long length, the cylinder body of desired length is made by cutting transversely of the cylinder body, the cut extending, of course, the through all the ribs and the cylinder body so that the end faces of the ribs and the cylinder body coincide substantially in a given plane transversely of the cylinder axis, as shown in FIG. ll of the drawing. The end faces 9 of the ribs are then drilled and tapped at ll, if the ribs are solid, or are simply tapped, if the ribs are formed with through bores lb, and, with the piston assembly 3 and piston rod 4 installed in the cylinder 2 at any convenient time after the cylinder body is cut and before the cylinder heads are attached to the cylinder body, the cylinder heads 5 and 6 are attached to the ends of the cut cylinder body by means of standard uniform length screws 7 inserted through the cylinder heads 5 and 6 into tapped holes ll of ribs 3.
From the foregoing, it is seen that regardless of the length of the cylinder body, standard uniform length screws may be utiliaed to attach the cylinder heads to the cylinder body, the length of the screw being determined solely by the thickness of the cylinder head. Moreover, if the ribs are formed to include through bores, the transverse cutting of the cylinder body at any point along its axis provides a convenient already existing hole in the rib end face which hole may be tapped without necessitating drilling.
