Abstract
A mounting assembly for mounting a pump to a fluid cylinder comprising a tie rod threaded at one end and providing a second end drivingly engageable with a sleeve-like threaded connection for clamping attachment directly into the cylinder block by the direct thread engagement of the connector internally of the cylinder block. The invention eliminates the requirement of machining a fluid cylinder block to provide engageable flanges and form nut pockets, thereby minimizing fabrication time and costs, while increasing strength, stability and alignment accuracy between pump pony rods and plunger assemblies of fluid cylinders generally of the type used for high pressure industrial applications.
Claims16
A mounting assembly for connecting a pump to a fluid cylinder comprising:
- a plurality of tie rods extending between and mechanically affixed to a pump frame and a fluid cylinder block;
- correspondingly axially aligned threaded bores in said pump frame and fluid cylinder block, one said tie rod extending along each axis;
- a sleeve-like threaded connector arranged at one end of each said tie rod having external threading threadably engaged with one of said bores of said fluid cylinder block;
- said tie rods including shouldered heads abuttably engaged by said sleeve-like connectors within said bores of said fluid cylinder block;
- said tie rods having opposites ends having threads being threadably engaged in said bores of said pump frame and further having a shoulder faced toward said pump frame;
- said tie rods extending internally of said fluid cylinder block and being clamped therein by said connectors.
A method of attaching a fluid cylinder to a pump comprising the steps of:
- (a) boring threaded first bores directly into a fluid cylinder block;
- (b) boring a like number of axially aligning threaded second bores having a smaller diameter than said first bores into a pump frame;
- (c) placing externally threaded sleeve-like connectors over first ends of a plurality of tie rods;
- (d) placing a spacer member onto said tie rods adjacent opposite threaded ends of said tie rods;
- (e) thread engaging said opposite threaded ends of said tie rod in said second bores of said pump frame;
- (f) inserting the said first ends of said tie rods into the axially aligning first bores in said fluid cylinder block;
- and,
- (g) turning said sleeve-like connectors to threadably engage the threaded first bores in said fluid cylinder block and urging block-inwardly said tie rods to abuttingly clamp against bottom walls of said first bores of said fluid cylinder block.
A tie rod and connector sleeve for use in mounting a pump to a fluid cylinder block:
- said tie rod comprising an elongate cylindrical-like member having a first end having threading of a diameter less than an adjacent portion of the tie rod thereby forming an annular shoulder, said threading being engageable with a threaded bore in a pump frame, a second end of said tie rod comprising a larger diameter shouldered head for insertion into a bore of a fluid cylinder block;
- and,
- said connector being sleeve-like with external threading and an internal passageway for sliding engagement over the tie rod to abut said shouldered head thereof and said external threading being thread engageable to a threaded bore in a fluid cylinder block to clamp the shouldered head therein.
