Abstract

The invention relates to a lifting mechanism for a double worm transmission line body, which is characterized by comprising a lifting air cylinder, a lifting push head and a rack, wherein the middle part of the lifting push head is provided with a gear, and the rack is connected with the lifting push head to drive the lifting push head to do rotary motion. The lifting air cylinder is connected with the lifting push head to push the lifting push head to do vertical motion. The rack drives the lifting push head to do rotary motion, the lifting air cylinder drives the lifting push head to do rotary motion at the same time, and the functions are not mutually affected. The lifting mechanism has the advantages that the lifting mechanism calculates the specific location of the follower fixture of the double worm transmission line body with stood workpieces by controlling the rotation speed of worms; the worms are applied to the transmission line body, so the use of the traditional worm for changing the direction of rotation is changed; the teeth of the follower fixture are only opened and are not closed; the frictional resistance is small, and the working efficiency reaches 0.9; the workpieces have an orientation function; and the orientation functions of other transmission modes are realized by guide rails, and the like.

The specific embodiment

Contrast accompanying drawing

1,2, double worm transmission line body comprise two worm screws and the pallet that rotation direction is opposite, and the tooth 3 that matches with worm screw is arranged on the pallet.Workpiece on the double worm transmission line body stands up, and also can crouch and put.

Contrast accompanying drawing 3, its structure are to comprise that jacking cylinder, jacking cut somebody's hair 7, tooth bar 8, and wherein there is gear at the jacking middle part of cutting somebody's hair, and tooth bar connects jacking and cuts somebody's hair and drive jacking and cut somebody's hair and rotate; The jacking cylinder connects jacking cuts somebody's hair and promotes jacking and cut somebody's hair and move up and down, and the rack drives jacking is cut somebody's hair and rotated and the jacking cylinder promotes jacking and cuts somebody's hair and move up and down and can carry out simultaneously, is independent of each other on the function.

Contrast Fig. 4, be used for the lifting body 18 on the double worm transmission line body that workpiece stands up, its structure comprises that jacking cylinder, jacking cut somebody's hair 7, tooth bar 8, and wherein there is gear at the jacking middle part of cutting somebody's hair, 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.

Contrast Figure 10, to be sliding rail 17 stand up and crouch between two double worm transmission line bodies putting at workpiece its structure, changes line manipulator 10 and can slide on sliding rail 17; Lifting body 18 is installed on the double worm transmission line body that workpiece stands up, and lifting body can eject pallet with the workpiece in the pallet; Described commentaries on classics line manipulator 10 comprises telescopic cylinder 13, guide pillar 11, clamps cylinder 12, clamp jaw 14, rotating mechanism 15, wherein clamp cylinder 12 and act on clamp jaw 14, can be with work-holding, the anchor clamps cylinder is fixed on the S. A. of rotating mechanism 15, rotating shaft terminal is changeing on the line manipulator by bearing installation, S. A. one end connects motor, and telescopic cylinder 13 is positioned at the S. A. top, does guide pillar 11 exist? the position play the guiding role.

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.

Embodiment 4, when workpiece need be transferred on the line delivery of putting that crouches from the line delivery that stands up, need to use commentaries on classics line manipulator.When the workpiece that stands up is transported on pallet when changeing line manipulator 10 times, the telescopic cylinder 13 that changes on the line manipulator stretches out, then clamp cylinder 14 with work-holding, telescopic cylinder 13 withdrawals, workpiece breaks away from pallet 6, rotating mechanism 15 on the manipulator turns over 90 °, manipulator travels to pallet 16 tops of crouching and to put, and the telescopic cylinder 13 that changes on the line manipulator stretches out, and then clamps cylinder 14 workpiece is put down, the line delivery of putting that crouches is seen workpiece off, so far finishes thread-changing.As shown in Figure 9.
