The utility model is characterized in that: an air cylinder (3) is arranged on the base seat (1) with a vertical piston bar (31). The upper end and the lower end of the piston bar (31) stretch out from the air cylinder (3). The upper end of the piston bar is connected with the connection board and the lower end is connected with a wedge lower inclined block (311). An upper inclined block (4) with a groove (41) is arranged on the base seat (1) and the upper inclined block can move along horizontal direction. The piston bar (31) passes through the groove (41) on the upper inclined block. The top surface of the lower inclined block (311) is parallel to the bottom surface of the upper inclined block (4).
Description
Technical field
The utility model relates to a kind of lifting mechanism of objective table, and the stroke that is specially adapted to objective table is less, and uses under the flexible and changeable situation of stroke.
Background technology
When making bicycle, all can process two rounds on the forward and backward wheel rim of bicycle usually, so that bicycle spoke to be installed; Since two rounds wheel rim axially on distance differ very little, in the prior art, adopt common cylinder transmission inaccuracy; In addition, for the wheel rim of different size, the distance between two rounds also has nothing in common with each other, and original equipment can't be adjusted flexibly according to process requirements.
Summary of the invention
The purpose of this utility model provides the lifting mechanism for objective table that a kind of transmission is accurate and stroke can change flexibly.
The technical solution of the utility model is: a kind of lifting mechanism of objective table, comprise pedestal, the connecting panel that is fixedly connected with objective table, has the guide rod that is provided with along vertical on the described pedestal, described connecting panel is set on the described guide rod slidably, also be set with cylinder on the described pedestal, has the piston rod that is provided with along vertical on the described cylinder, the upper end of described piston rod and bottom pass described cylinder respectively, the upper end of described piston rod and described connecting panel are fixedly connected, the bottom of described piston rod is fixedly connected with the following skewback of wedge shape, but also be provided with the last skewback that along continuous straight runs moves on the described pedestal, described going up on the skewback has groove, described piston rod passes described groove, the described upper surface level that goes up skewback, and the upper surface of described skewback down parallels with the described lower surface of going up skewback.Described going up on the skewback also is fixedly connected with connecting portion, is connected with screw mandrel on the described pedestal rotationally, described screw mandrel and the screw thread fit connection mutually of described connecting portion.
The utility model adopts two rod air cylinder driven objective tables, and by a pair of wedge shape skewback is set the stroke of cylinder can be changed flexibly; Use the screw mandrel transmission also can realize in addition, so it compared with prior art have driving efficiency height, transmission is accurate, easy to adjust, stroke can change flexibly advantage to stroke size ground accuracy controlling.

Wherein: 1, pedestal; 11, guide rod; 2, connecting panel; 3, cylinder; 31, piston rod; 311, following skewback; 4, go up skewback; 41, groove; 42, connecting portion; 5, screw mandrel.
The specific embodiment
Referring to accompanying drawing 1 to shown in the accompanying drawing 5, a kind of lifting mechanism of objective table, comprise pedestal 1 that is connected with supporting object and the connecting panel 2 that is fixedly connected with objective table, pedestal 1 is exactly the part of the frame of main equipment usually, and connecting panel 2 also can be directly as the objective table that carries workpiece.
Have a plurality of guide rods 11 that are provided with along vertical on the pedestal 1, connecting panel 2 is set on the guide rod 11 slidably, and connecting panel 2 slides along guide rod 11 verticals and just can realize lifting (" vertical " described in this specification sheets refers to the above-below direction in the accompanying drawing 1) to wheel rim.
Also be set with cylinder 3 on the pedestal 1, cylinder 3 adopts two rod cylinders, as shown in Figure 1, has the piston rod 31 that is provided with along vertical on the cylinder 3, and the upper end of piston rod 31 and bottom pass respectively outside the cylinder 3, when driving cylinder 3, and piston rod 31 whole upward movements.
For the stroke that makes cylinder 3 can change flexibly, the upper end of this piston rod 31 and connecting panel 2 are fixedly connected, and the bottom of piston rod 31 is fixedly connected with the following skewback 311 of wedge shape.Simultaneously, but the screw mandrel 5 that also is provided with last skewback 4 that along continuous straight runs moves on the pedestal 1 and can rotates along self axial line, have groove 41 on the last skewback 4, the bottom of piston rod 31 is passed groove 41 backs and is linked to each other with following skewback 311, and the upper surface level of last skewback 4, and upward the lower surface of skewback 4 parallels with the upper surface of following skewback 311.Therefore when the Lifting carrying platform, drive cylinder 3, make piston rod 31 drive skewback 311 upward movements down, stop on the skewback 4 up to descending skewback 311 to be against, the upper surface of promptly going up the lower surface of skewback 4 and following skewback 311 respectively and the line distance that intersects between two intersection points that produce of same plumb bob vertical be the stroke of cylinder 3, this segment distance is exactly the distance D in the accompanying drawing 5.
By skewback on the parallel motion 4, the accurate size of control travel D.Be connected with a connecting portion 42 on the last skewback 4, has tapped bore on the connecting portion 42, screw mandrel 5 and connecting portion 42 screw thread fit connection mutually, therefore by rotary screw rod 5 skewback 4 along continuous straight runs are moved, can accurately grasp the angle of screw mandrel 5 rotations and the variation relation of stroke by the design of thread and pitch, thereby accurately grasp the lifting distance of objective table.
