Examples: in some work filling stations, it is often necessary to insert the device into another work piece in a cyclic and reciprocating manner, in which process not only the insertion action but also the feeding action is required, and in general both structures are driven by different motors, which not only requires very precise control of the driving frequency, but also increases the cost in an intangible way.

In general, most of the processing flows of two action stations in the process are basically the same, firstly, a raw material workpiece is sent to a certain set position, at this time, the raw material workpiece is kept motionless, then is sent to another required processing position through another station, and needs to be reset after being sent to a destination, at this time, the previous station is reset and waits for the next round of processing, for example, in the inserting process of a commutator, firstly, a copper sheet to be inserted needs to be sent to a certain place, at this time, the copper sheet is kept motionless, then the copper sheet is pushed (extruded) into a commutator ring core through another station, at this time, the station and the previous station are reset before and after, and wait for the next round of inserting process, most of structures in the prior art are driven by two driving motors, and in the process, enterprises increase operation and maintenance cost and equipment investment cost.

Based on this, this scheme has provided a double cam multistation structure, can realize the action of automation, and the realization that circulates promptly sends the work piece to the purpose in predetermined place to whole frock only uses a motor, very big reduction the input cost of enterprise.

Referring to fig. 1-5, the scheme mainly includes three parts of a frame 1, a longitudinal station 2 and a transverse station 3, the longitudinal station 2 includes a first slider 21 capable of sliding reciprocally along the height direction of the frame 1, the transverse station 3 includes a second slider 31 capable of sliding reciprocally along the length direction of the frame 1, the frame 1 is L-shaped, and the first slider 21 and the second slider 31 are respectively located on two end faces of the concave surface of the frame 1.

For example, when the second slider 31 is used for fixing a feeding mechanism and the material to be assembled moves to one side of the frame 1 through the second slider 31, the second slider 31 moves the material towards the direction where the first slider 21 is located, and the first slider 21 is used for pushing the material of the second slider 31 downward to a destination, and after the first slider 31 is reset, the second slider 31 is reset to one side far from the first slider 31 and waits for the next cycle. (the orientation in this example is adapted to the workpiece to be assembled being at the bottom end of the frame 1 and directly below the first slider 21. The second slider 31 may be provided with a storage slot for the material to be assembled. When the first slider 21 is moved downwards, the material in the slot is pushed into the workpiece, the particular workpiece not shown)

The two sliding blocks are driven by a motor, specifically, a gear motor 11 is installed on the frame body 1, the output shaft end of the gear motor 11 is connected with a driving wheel 111, the rear sides of the first driving disc 22 and the second driving disc 32 are connected with a driven wheel 112, and the driving wheel 111 is in transmission connection with the two driven wheels 112 through a belt.

When the gear motor 11 is started, the first driving disc 22 and the second driving disc 32 rotate synchronously, the diameters of the first driving disc 22 and the second driving disc 32 in the scheme are unequal, an eccentric groove 4 is respectively formed in the end faces of the first driving disc 22 and the second driving disc 32, one side of the first sliding block 21 and one side of the second sliding block 31 roll in the eccentric groove 4 on the first driving disc 22 and the second driving disc 32 respectively through one guide wheel 5, the eccentric groove 4 is not in a regular circle, when the driving discs rotate, the stress magnitude and the stress direction of the guide wheels 5 in the eccentric groove 4 can be changed along with the path of the groove body, and due to the unequal diameters of the two driving discs, any one sliding block can be subjected to various motion states in the rotating process, namely a reciprocating motion state and a stagnation state, when one sliding block is stopped, the other sliding block starts to be stressed and starts to move, and an intermittent working state is formed.

The eccentric slot 4 mainly comprises a connecting part 41, a transition part 42 and a turning part 43, as shown in fig. 3, when the guide wheel 5 on the first driving disc 22 is in the connecting part 41 (in a stagnation state), the guide wheel 5 of the second driving disc 32 can start to move in the turning part 43, and in the next stroke, the guide wheel 5 in the first driving disc 22 can go through the turning part 43 to complete the rolling of the connecting part 41, and the guide wheel 5 in the second driving disc 21 starts to move towards the connecting part 41 after the next transition part 42 is moved in parallel, so as to start to enter the stagnation state.

Specifically, the connecting portions 41 and the turning portions 43 on the first driving disc 22 and the second driving disc 32 in this case are concentric with the driving disc, the transition portions 42 are provided with two portions and symmetrically distributed on two sides of the connecting portions 41, and the transition portions 42 are concave from one side of the connecting portions 41 toward one side of the connecting portions 41, protrude in a direction away from the connecting portions 41, and extend in a direction away from the turning portions 43.

The difference is that the length of the extending path from the transition portion 42 to the turning portion 43 on the first driving disc 22 and the second driving disc 32 is different, and the angle of the bending extending is also different, in practice, the length of the path and the running time for driving the sliding block to move can be achieved according to the length of the path and the bending angle of the customized position which are actually required.

In this case, the distance between the outer edge of the connecting portion 41 on the first driving disc 22 and the center of the first driving disc 22 is smaller than the distance between the outer edge of the turning portion 43 and the center of the first driving disc 22, the distance between the connecting portion 41 on the second driving disc 32 and the center of the second driving disc 32 is larger than the distance between the outer edge of the turning portion 43 and the center of the second driving disc 32, and meanwhile, the radius of the first driving disc 22 is larger than the radius of the second driving disc 32, and the radius ratio is about 3:2.

that is, the distance between the transition portion 42 on the side of the connection portion 41 on the first driving disc 22 is longer, for example, in fig. 3, when the driving disc rotates clockwise, the second driving disc 32 starts to roll at the connection portion 41, the second slider 31 will move to the left in the drawing, the guide wheel 5 will travel in the groove of the whole connection portion 41, the second slider 31 will keep the stagnation state because the connection portion 41 is concentric with the driving disc and the diameters are different, the guide wheel 5 in the first driving disc 22 will drive the first slider 21 to move downwards, the moving distance is the distance between one transition portion 42 and the turning portion 43, when the turning portion 43 is completely moved, the guide wheel 5 in the second driving disc 32 starts to travel in the other transition portion 42, the guide wheel 5 in the second driving disc 32 will travel to the whole connection portion 41 to contact with the transition portion 42 on the right in the drawing, the first slider 21 will move upwards and reset, and the second slider 31 will move rightwards and reset.

In this case, the connecting portion 41 of the first driving disc 22 is a half-half semicircular groove, the radian of the turning portion 43 of the first driving disc 22 is 20 °, the whole transition portion 42 is curved in an S-shape, the outer edge is changed from a concave surface to a convex surface, and one side of the convex surface is connected with the turning portion 43.

The connecting portion 41 of the second driving disc 32 is in the shape of a two-thirds circular groove, the radian of the turning portion 43 of the second driving disc 32 is 60 degrees, the overall curved track of the transition portion 42 is approximately similar to that of the transition portion 42 on the first driving disc 22, but the difference is that the overall length of the transition portion 42 is smaller, the ratio of the lengths of the concave surface and the convex surface formed by the outer edges is different, and the length of the concave surface of the transition portion 42 on the second driving disc 32 is greater than the length of the convex surface, which is opposite to the ratio of the length of the concave surface of the transition portion 42 on the first driving disc 32 to the length of the convex surface.

The moving modes of the first slider 21 and the second slider 31 are not particularly limited, and sliding structures such as sliding pipes and sliding rods can be used for guiding and sliding on the frame body 1 in the present case in a sliding rail mode.
