Description
Technical field
The utility model 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.
Model utility content
For the problems referred to above, the utility model provides a kind of crank rocker device of adjustable ram travel, can the stroke of adjusting slider at any time, can regulate, use flexibly under the state of not arresting stop work.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model 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 beneficial effects of the utility model are: can the stroke of adjusting slider at any time, can regulate, use flexibly under the state of not arresting stop work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the crank rocker device of the adjustable ram travel of the utility model;
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 solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
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 preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification 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 utility model.
