Description
Technical field
The utility model relates to a kind of cylinder, especially relates to a kind of jacking apparatus cylinder synchronizer gear.
Background technology
Cylinder is synchronously an important content in pneumatics, in the design process of white vehicle body welding fixture, often can adopt two or more cylinder as power to realize the jack-up of bodywork parts.In order to realize the synchronization action of cylinder, usually adopt mechanical connection to force each cylinder synchronization action, the method structure is simple, with low cost, use more extensive.But the uncertainty of drag size suffered by two cylinders easily makes rigidly connected two cylinders occur stuck phenomenon, thus the normal work of impact.
As shown in Figure 1, strip structure is certain rigid connector to existing jacking apparatus, and the take-off lever of two synchronous cylinders is linked together by rigid connector, and point of connection is respectively M1, P1, and ideally two cylinders can be synchronized with the movement.In fact when the cylinder elder generation action on the left side, theoretical power output is F, rigid connector is subject to the effect of moment of rotation M=FL1, and this moment of rotation is impelled between the cylinder take-off lever on rigid connector and the right and occurred stuck phenomenon, and the take-off lever of the right cylinder can not normally be stretched out.
Utility model content
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists a kind of maintain jacking apparatus cylinder stress equalization, ensure the jacking apparatus cylinder synchronizer gear that cylinder running velocity is identical with trend.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of jacking apparatus cylinder synchronizer gear, described jacking apparatus comprises rigid connector, and with it rigidly connected two or more cylinder, it is characterized in that, synchronizer gear is provided with between adjacent two cylinders, this synchronizer gear comprises stationary rack, and the two groups of rack and pinion assemblies be arranged on this stationary rack, often organize rack and pinion assembly and include stay bearing plate, gear and movable rack, wherein stay bearing plate connects rigid connector, movable rack is fixed on stay bearing plate side, and and gears meshing, gear and stationary rack are connected with a joggle.
Two groups of described rack and pinion assemblies are positioned at stationary rack two ends, respectively near the cylinder of both sides.
The rectangular triangle of described stay bearing plate, one bar square edge is fixed on rigid connector, and another square edge is fixedly connected with movable rack.
Engage with stationary rack bottom described gear, side is engaged with movable rack.
Stationary rack is arranged on guide rail.
Compared with prior art, the utility model has the following advantages:
(1) stay bearing plate adopts right angle trigonometry frame, and good stability is not yielding.
(2) gear and tooth bar engaging mechanism is adopted, reproducible, long service life.
(3) stationary rack is arranged on guide rail, guarantees that tooth bar path of motion remains unchanged, and improves synchronous effect.
(4) be applicable to two or more cylinder synchronous, applicability is wide.
(5) the method structure is simple, with low cost.
Accompanying drawing explanation
Fig. 1 is the path of motion schematic diagram of existing jacking apparatus;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is rigid connector path of motion schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 2, the synchronizer gear that the utility model comprises left cylinder 51, right cylinder 52, stationary rack 2, rigid connector 6 and is arranged between two cylinders, wherein synchronizer gear comprises stationary rack 2 and the left gear tooth bar assembly that is arranged on this stationary rack 2 and right gear tooth bar assembly.Wherein left gear tooth bar assembly comprises left support plate 11, left gear 31 and left movable rack 41, and right gear tooth bar assembly comprises right support plate 12, right gear 32 and right movable rack 42.
Take-off lever and the rigid connector 6 of left cylinder 51 just connect, left support plate 11 is triangle at right angles, one bar square edge is fixed on rigid connector 6, another square edge is fixedly connected with movable rack 41, and therefore left support plate 11, left movable rack 41 are synchronized with the movement with the take-off lever three of left cylinder 51.Left gear 31 center-point is fixed, and bottom is engaged with stationary rack 2, and side is engaged with left movable rack 41, and stationary rack 2 is arranged on dovetail furrow guide rail or cylindrical guide.Right cylinder 52 position and left cylinder 51 are symmetrical, among right synchronizer gear the position of each several part and annexation identical with left synchronizer gear.
As shown in Figure 3, rectangular in figure is the rigid connector 6 of mechanism, point M1, N1 are respectively the point of connection of the take-off lever of left cylinder 51, left support plate 11 and rigid connector 6, and some O1, P1 are respectively the point of connection of the take-off lever of right cylinder 52, right support plate 12 and rigid connector 6.When left cylinder 51 first upward movement, M1 point on rigid connector 6 is pushed to M2 point position by its take-off lever, now because a M1 and some N1 is apart from very near, the moment of rotation M=FL2 that rigid connector 6 is subject to is very little, the point N1 driven on rigid connector 6 is moved to a N2 by left support plate 11, left movable rack 41 also moves thereupon, left gear 31 is driven to rotate by left movable rack 41, left gear 31 drives stationary rack 2 to be moved to the left, stationary rack 2 drives right gear 32 to rotate, right gear 32 drives right tooth bar 42 and right support plate 12 to move up, point O1 will move to an O2, point P1 will move to a P2, thus drive the take-off lever upward movement of right cylinder 52, synchronization action is realized with left cylinder 51.
In like manner, if right cylinder 52 first moves, left for drive cylinder 51 is also realized synchronization action by this structure, thus ensures that the running velocity of cylinder is identical with operation trend, avoids the phenomenon that machinery is stuck.
