The specific embodiment

Contrast accompanying drawing

1,2,5, the structure of double worm transmission line body is the pallet 6 that comprises that two worm screws 2 that rotation direction is opposite and workpiece stand up, the tooth that matches with worm screw is arranged on the pallet, workpiece on the double worm transmission line body stands up, the two ends of two worm screws uses bearing fixing respectively on frame, wherein one has helical wheel, helical wheel engagement on this helical wheel and the drive motor, the pallet of the double worm transmission line body that workpiece stands up comprises liner, the tooth that matches with worm screw, the lower part of tooth cooperates with guide rail, and columnar workpiece has guide function to pallet.

Contrast Fig. 4 is used for the lifting body on the double worm transmission line body that workpiece stands up, comprises that jacking cylinder, jacking are cut somebody's hair, tooth bar, and wherein there is gear at the jacking middle part of cutting somebody's hair, and tooth bar connects jacking cuts somebody's hair, and cuts somebody's hair and rotates so tooth bar can drive jacking; The jacking cylinder connects jacking cuts somebody's hair, and cuts somebody's hair and moves up and down so the jacking cylinder can promote jacking, and the rack drives jacking is cut somebody's hair and rotated and jacking cylinder promotion jacking is cut somebody's hair and moved up and down and can carry out simultaneously, is independent of each other on the function.

Contrast Fig. 5, Fig. 7, the tooth 3 that the pallet of the double worm transmission line body that workpiece stands up comprises liner 5, matches with worm screw, the lower part of tooth 3 cooperates with guide rail, and columnar workpiece has guide function to pallet.

The crouch pallet of the double worm transmission line body put of workpiece comprises vee-block, the tooth that matches with worm screw, and two worm drive pallets that rotation direction is opposite are fed forward, and pallet is subjected to track restrained on the frame.

Embodiment 1, and in double worm transmission line body, the two ends of two worm screws uses bearing fixing respectively on frame, and wherein one has helical wheel, and the helical wheel engagement on this helical wheel and the drive motor can guarantee to act in agreement when two worm screws are rotated like this.As shown in Figure 8.

Embodiment 2, and workpiece is a column, for example are cylindrical, and when workpiece stood up, the profile of tooth of worm screw was made up of two parts, and a part is the part of the root and the close root of worm screw profile of tooth, and another part is the part of tooth top and the close tooth top of worm screw.As shown in Figure 2.

The part of the root of worm screw profile of tooth and close root, the tooth engagement with on the pallet is used to drive pallet and is fed forward; And the part of tooth top of two worm screws and close tooth top is made into the shape that matches with cylindrical work, and as shown in Figure 5, the line body drives pallet and is fed forward in the process, and cylindric workpiece has directional tagging.

Embodiment 3, and when workpiece crouched and to put, columnar workpiece was placed on the vee-block, and pallet 16 relies on its deadweights to make its tooth and worm mesh, and when worm screw was rotated, the both sides of pallet contacted with track on the frame, and track plays effect of contraction to the left and right directions of pallet.As Fig. 6, shown in Figure 7.
