Abstract
The present invention relates to the field of pump and the reciprocator is a machine driving piston and driving working machine to reciprocate linearly. The eccentric wheel of the gear box drives the link and rack to move leftwards, the oscillating gear and driving block of the two-way pump are made to rotate clockwise and the driven block counterclockwise, oil is pressed from the pump cavity to the left hydraulic cavity to drive the piston to move rightwards while the oil is made to return from the right cavity to the pump cavity. When the rack is made to move rightwards, the said parts are made to move in the opposite directions. When matched with adjustable gear box and changing the central distance of the eccentric wheel, may be obtained varying speed and changeable stroke.
Description
Two-way pump hydraulic straight line reciprocator of the present invention adheres to the pump field separately, is the hydraulic machinery that a kind of driven plunger drives the working machine straight reciprocating motion.
The background technique of two-way pump linear reciprocation machine: mechanical industry is published the mechanical general teaching material of technical school " machine foundation " chapter 4 of publishing in July, 1980, hydraulic transmission.
Hydraulic transmission, at transport facility, building machinery, particularly aspect such as metal cutting such as broaching machine, grinding machine obtains extensive use.Hydraulic transmission is compared with mechanical transmission, electric drive, has stable drive, in light weight, volume is little, bearing capacity is big advantage.Should see: background technique exists narrow limitation, promptly under the amount of the acting on situation big, simple straight reciprocating motion, also must the adapted commutation, mechanisms such as throttling, overflow, and the hydraulic transmission demand of simplification and the structure of background technique can't be simplified.Respective outer side edges such as two-way pump hydraulic straight line reciprocator of the present invention need not commutation, throttling, overflow can satisfy the straight reciprocating motion needs of working machine, can be widely used in lathe to-and-fro motion working platform, some frequent jacking equipment, aspects such as oil-field oil pumper.
Two-way pump hydraulic straight line reciprocator of the present invention mainly is made of a two-way pump and gearbox, oil hydraulic cylinder.Realize that technological scheme of the present invention is: the driving shaft of two-way pump and initiatively piece, driven axle are with each is fixedlyed connected by motion block, be cemented in the driving tooth of active piece one end and be cemented in and mesh by the passive tooth opposite position of motion block one end, a piece and scraper plate and a leaf spring respectively are housed in the groove of the motion block the other end initiatively, a pumping hole is respectively left in pump housing both sides, each is hinged with the pump housing and end cap for driving shaft and driven axle two ends, the pump housing is fixedlyed connected with end cap, and the axle envelope is housed between driving shaft and the end cap.The outer fixedly connected wobble gear of an end of the pump of driving shaft, two-way pump is fixedly connected on support one end, the fixedly connected gearbox of the support the other end, eccentric wheel on the gearbox is parallel with connecting rod hinged, the connecting rod the other end and tooth bar are hinged, two groups of directed pulleys are supported tooth bar and wobble gear engagement, and each fixedlys connected the seat of directed pulley with support.Each fixedlys connected the piston two ends of hydraulic cylinder cavity with a piston rod, each fixedlys connected oil hydraulic cylinder with a cylinder head seated that leaves upper interface and bottom interface, two exhaust fuel feeding valves are respectively fixedlyed connected with upper interface, between two piston rods and the cylinder head seated oil sealing is housed, two liquid Guan Yiduan each with a pumping hole of two-way pump, each fixedlys connected the other end with the bottom interface of cylinder head seated, and two liquid pipes respectively are furnished with a cooling jacket outward.
