Abstract
The invention discloses a multi-position load-bearing telescopic mechanism. The multi-position load-bearing telescopic mechanism comprises a machine frame, two linear guide rails, a cylinder a, a cylinder b, a cylinder connecting block and a connecting block. The two linear guide rails are fixedly installed on two sides of the machine frame respectively, every linear guide rail is internally provided with a linear slideway, sliding block ends are installed on the two linear slideways respectively, part of every sliding block end is located in the linear guide rails, another part of every sliding block end is located outside the linear guide rails, the tail end of a cylinder body of the cylinder a and an extending-out rod end of the cylinder b are installed in a series connection through the cylinder connecting block, an extending-out rod end of the cylinder a is connected with the sliding block ends of the two linear guide rails through the connecting block, and a cylinder body of the cylinder b is fixedly connected with the machine frame. Rapid stretching of the guide rails at fixed positions is achieved pneumatically on the premise that large loads are borne in every direction.
Description
Technical field
The present invention relates to a kind of telescoping mechanism, particularly can bear the telescoping mechanism of multi-direction heavy load.
Background technology
While needing allocation mobile object in daily production, life, the general form that adopts cylinder directly to drive, but owing to having certain gap between cylinder piston rod and cylinder body, therefore it is generally merely able to bear the pressure from axial, other directions do not possess large bearing capacity.Industrial when need to carry multiple directions load, T-shaped or the dove-tail form linear ramp of general employing, simultaneously in conjunction with actuators such as motors, realize rectilinear motion, high-rigidity multi-stage expansion mechanism as disclosed in application for a patent for invention CN200910091097, has realized high rigidity, the motion of high-precision linear telescopic.But because motor is originally as rotatablely moving, is converted into and drives guide rail rectilinear motion, also must coordinate screw-nut structure, overall structure relative complex, and pick and place application scenario for industrial allocation, use the drive form of servomotor, speed is slow, and controls complicated.
Summary of the invention
The object of this invention is to provide under guaranteeing that all directions are born compared with the prerequisite of heavy load, by pneumatic a kind of multiposition load telescoping mechanism of realizing the quick-expansion of guide rail allocation.
A multiposition load telescoping mechanism, comprises frame, two line slideways, cylinder a, cylinder b, cylinder contiguous block, contiguous block; Two line slideways are fixedly mounted on respectively frame both sides; Linear ramp is all set in each line slideway, a slider end is respectively installed on two linear ramps, and a part for each slider end is positioned at line slideway, another part of each slider end is positioned at outside line slideway; The rod end that stretches out of the cylinder body end of cylinder a and cylinder b is installed in series by cylinder contiguous block, and the rod end that stretches out of cylinder a is connected with the slider end of two line slideways by contiguous block, and the cylinder body of cylinder b is fixedly connected in frame.
A kind of multiposition load telescoping mechanism also comprises:
The linear ramp of two line slideways and slider end are T-shaped or dove-tail form, and two line slideway space parallels.
The active length of the active length of cylinder a and cylinder b is unequal.
Beneficial effect of the present invention:
Owing to adopting pneumatic direct driving, the operating rate of mechanism drives fast compared with motor; And adopting guide rail ruggedized construction in parallel, more conventional Telescopic-cylinder guide rail, has again the load capacity of multi-direction large load.
Accompanying drawing explanation
Fig. 1 is the overall structure sketch of telescoping mechanism;
Fig. 2 is the cylinder coupling part structure diagram of telescoping mechanism;
The position length figure of telescoping mechanism when Fig. 3 inflates for cylinder a5 is pressurizeed separately;
The position length figure of telescoping mechanism when Fig. 4 inflates for cylinder b6 is pressurizeed separately;
The position length figure of Fig. 5 telescoping mechanism when cylinder a5 and cylinder b6 being pressurizeed simultaneously to inflation.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.As shown in Figure 1 and Figure 2, three grades of telescoping mechanisms of the present invention comprise a frame 1 that supports all execution units, the both sides of frame are installed with respectively line slideway a2 by securing member 4, with line slideway b3, line slideway adopts has the T-shaped of higher stiffness and precision or dove-tail form linear ramp, during installation, two line slideways need the fully depth of parallelism in assurance space, otherwise whole mechanism can produce extra resistance to sliding because of 2 influencing each other of guide rail.Line slideway a2 and line slideway b3 have formed slip load part, because adopting the linear ramp with stronger rigidity and precision, it not only can bear the larger load on axis direction, and can bear the load of other all directions, and by being installed in parallel of 2 line slideways, further strengthened the ability of bearing other direction load.Together with cylinder a5 is installed in series by cylinder contiguous block 7 with cylinder b6, wherein extension bar one end of cylinder a5 is connected with the slider end of line slideway b3 with line slideway a2 by contiguous block 8, and the cylinder body of cylinder b6 is fixed in frame 1 by securing member 4.Contiguous block 8, as end, can be installed tong etc., to realize the final workpiece that picks and places, or other executing agencies.
As shown in Fig. 3,4,5: cylinder a5, cylinder b6, according to need of work, select the cylinder of suitable extension elongation; During work, when inflation that cylinder a5 is pressurizeed separately, the active length that contiguous block 8 of mechanism's end stretches out cylinder a5; When inflation that cylinder b6 is pressurizeed separately, the active length that contiguous block 8 of mechanism's end stretches out cylinder b6; When inflation that cylinder a5 and cylinder b6 are pressurizeed simultaneously, the contiguous block 8 of mechanism's end stretches out the stack active length of cylinder a5 and cylinder b6.
When the active length of cylinder a5, cylinder b6 is different, it is flexible that mechanism can realize the allocation of three different lengths.
