Abstract
The invention discloses a crank rocker device capable of adjusting the stroke of a slider. The crank rocker device comprises a crank and a rocker and is characterized in that one end of the crank is hinged to a rack, the other end of the crank is hinged to one end of the rocker through a first connecting rod, an eccentric shaft is arranged on the rocker, a gear is fixedly arranged on the eccentric shaft, the gear is meshed with an adjusting gear, the adjusting gear is arranged on the rack, the other end of the rocker is hinged to a second connecting rod, the tail end of the second connecting rod is hinged to the slider, and the second connecting rod drives the slider to move along a guide rail on the rack. Preferentially, the diameter of the gear is larger than that of the adjusting gear. Preferentially, the eccentric shaft is arranged in the center of the rocker. The stroke of the slider can be adjusted any time without shutting down the device, and usage is flexible.
Description
Technical field
The present invention relates to a kind of crank rocker device of adjustable ram travel.
Background technique
Crank rocker device is in the process driving slide block movement, and the stroke of its slide block is generally fixing or has set, in the process of crank rocker device work, generally cannot adjusting slider stroke, and this brings inconvenience in actual production.
Summary of the invention
For the problems referred to above, the invention provides a kind of crank rocker device of adjustable ram travel, can the stroke of adjusting slider at any time, can regulate under the state of not arresting stop work, use flexibly.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
The crank rocker device of adjustable ram travel, comprise crank and rocking bar, it is characterized in that, described crank one end is hinged in frame, the other end is hinged by one end of first connecting rod and rocking bar, described rocking bar is provided with eccentric shaft, described eccentric shaft is fixedly installed gear, described gear and an adjusting gear are meshed, described adjusting gear is arranged in frame, the other end of described rocking bar is hinged with second connecting rod, and described second connecting rod end is hinged with a slide block and with movable slider along the guide rail movement in frame.
Preferably, the diameter of described gear is greater than the diameter of adjusting gear.
Preferably, described eccentric shaft is arranged on the center of rocking bar.
Wherein, adjusting gear can rotate by the tie point in frame, rotates the position of the adjustable gear of adjusting gear, accordingly, have adjusted the throw of eccentric of eccentric shaft, make the fulcrum of rocking bar of adjustable eccentric shaft, thus the stroke of adjusting slider, and, regulate and do not affect by the state of time and device.
The invention has the beneficial effects as follows: can the stroke of adjusting slider at any time, can regulate under the state of not arresting stop work, use flexibly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crank rocker device of the adjustable ram travel of the present invention;
The mark implication of accompanying drawing is as follows:
1: crank; 2: first connecting rod; 3: rocking bar; 4: eccentric shaft; 5: gear; 6: adjusting gear; 7: second connecting rod; 8: frame; 9: slide block; 10: guide rail.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
The crank rocker device of adjustable ram travel, as shown in Figure 1, comprise crank 1 and rocking bar 3, described crank 1 one end is hinged in frame, namely crank 1 and frame are articulated with a place, the other end is hinged with one end of rocking bar 3 by first connecting rod 2, and namely the b end of first connecting rod 2 is hinged with crank 1, and c end is hinged with rocking bar 3.Described rocking bar 3 is provided with eccentric shaft 4, and its shaft core position is e point.Preferably, eccentric shaft 4 is arranged on the center of rocking bar 3, and described eccentric shaft 4 is fixedly installed gear 5, and described gear 5 and an adjusting gear 6 are meshed, and wherein, the diameter of gear 5 is greater than the diameter of adjusting gear 6.Gear 5 can rotate along center of circle d point, and it can be arranged in frame.Described adjusting gear 6 is arranged in frame, can rotate around center of circle f point.
The other end (the g end namely in figure) of described rocking bar 3 is hinged with second connecting rod 7, and generally speaking, described first connecting rod 2 is identical with second connecting rod 7 length.Described second connecting rod 7 end and h place are hinged with a slide block 9, and second connecting rod 7 moves along the guide rail 10 in frame 8 with movable slider 9.
Wherein, the distance of center circle L of described gear 5 and eccentric shaft 4 is 10-50mm, can be 20mm, 30mm etc.
Wherein, adjusting gear 6 can rotate by the tie point f point in frame, rotate the position that adjusting gear 6 can regulate large gear 5, accordingly, have adjusted the throw of eccentric of eccentric shaft 4, make the fulcrum of rocking bar 3 of adjustable eccentric shaft 4, thus the stroke of adjusting slider 9, and, regulate and do not affect by the state of time and device, use flexibly.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
