The table top 4 is used as a main operation area, and a clamp mechanism 7 is arranged on the table top 4 for fixing metal materials (mainly metal plates), and the clamp mechanism 7 can be an existing conventional clamp, such as an existing clamp for polishing the metal materials, and mainly plays a role in fixing the metal materials. In order to improve polishing efficiency, it is common practice to drive the polishing mechanism 6 through a displacement assembly, so that the polishing mechanism 6 automatically moves to polish back and forth, and the displacement assembly can adopt a linear guide rail which is respectively arranged transversely and longitudinally, but the linear guide rail has higher cost and is easy to break down, and the screw rod screw has the same problem. The crank push rod mechanism has simple structure and lower cost, can be used as a driving component for linear movement, but the traditional crank push rod mechanism has the problem of larger vibration, as shown in fig. 1, mainly because one end of a crank 1 of the traditional crank push rod mechanism is fixed, the other end of the crank push rod mechanism performs circular movement to drive one end of a push rod 2, so that the other end of the push rod 2 is driven to perform linear movement, a linear movement path of a piston 3 is used as a center line, the positions of one end of the push rod 2 are alternated on two sides of the center line, when an included angle exists between the push rod 2 and the center line, acting force in the radial direction is generated on the piston 3, the positive and negative alternation of the direction of the acting force can generate vibration, and meanwhile, part of energy provided by the crank 1 can be consumed in an invalid way.
In the invention, a crank push rod mechanism is specially improved, as shown in fig. 3, by arranging an annular gear 13 and a planetary gear 14, wherein the diameter of the annular gear 13 is twice that of the planetary gear 14, one end of a gear side crank 15 is fixedly connected with the axle center of the planetary gear 14, the rotation axle center of the push rod 16 rotationally connected with the gear side crank 15 is positioned on the indexing circle of the planetary gear 14, and when the axle center of the planetary gear 14 and the axle center of the annular gear 13 are positioned on the same vertical plane, the rotation axle center of the push rod 16 rotationally connected with the gear side crank 15 is positioned at the center of the annular gear 13. Therefore, when the driving motor 11 drives the planetary gear 14 to rotate in the ring gear 13 through the motor side crank 12, the rotation axis of the rotation connection of the push rod 16 and the gear side crank 15 moves left and right along the horizontal center line of the ring gear 13, and the other end of the push rod 16 is slidably connected with the U-shaped frame 8, so that the whole push rod 16 moves left and right along the horizontal center line of the ring gear 13, the force in the radial direction generated at the piston is greatly reduced, the vibration is greatly reduced, and the ineffective consumption of the energy of the driving motor 11 is also reduced. According to the invention, the polishing mechanism 6 is driven to move left and right by the improved crank push rod mechanism, so that the polishing of the metal material is completed, and the whole device has a good vibration reduction effect and high energy utilization rate. In order to balance the weight of the two sides of the motor side crank 12 and further reduce vibration, a balancing weight can be arranged at the other end of the motor side crank 12 opposite to the connecting planetary gear 14, and the weight of the balancing weight is suitable for meeting the matching of the loads at the two ends of the motor side crank 12.

In order to reduce the number of motors and realize the transverse and longitudinal movement of the polishing mechanism 6 by using a single motor, the invention particularly designs the longitudinal displacement assembly 10 matched with the transverse displacement assembly 9, the sliding grooves 19 on the guide plate 17 form an integral S-shaped structure, and one end of each sliding groove 19 positioned on the front side and the rear side is independently provided with no connecting part 20. Initially, the top end of the guide rod 18 is located at the independent end of the sliding groove 19 on the front side or the rear side, taking the independent end of the sliding groove 19 on the front side as an example, that is, the top end of the guide rod 18 is initially located at the right end of the uppermost sliding groove 19 in fig. 3, when the push rod 16 polishing mechanism 6 drives the guide rod 18 to slide leftwards into the connection part 20, the connection part 20 guides the guide rod 18 to drive the polishing mechanism 6 to move transversely and simultaneously move longitudinally, in the longitudinal direction, the polishing mechanism 6 slides on the push rod 16, along with the longitudinal displacement of the guide rod 18, the guide rod 18 presses the limiting block 25 towards the inside of the mounting groove 22 through the inclined surface 26 on the limiting block 25, so that the limiting block 25 is allowed to move the guide rod 18 into the reversing groove 21, after the guide rod 18 enters the reversing groove 21, the spring 24 pushes the limiting block 25 out of the mounting groove 22 to continue limiting, the push rod 16 also reaches the stroke reset to start pulling the guide rod 18 rightwards, in the rightward moving process of the guide rod 18, the guide rod 18 slides to the other side of the connecting part 20 to enter the lower adjacent sliding groove 19 due to the limiting of the limiting block 25, after the guide rod 18 reaches the right end of the lower adjacent sliding groove 19, the guide rod 18 is repeatedly operated in the connecting part 20, the longitudinal stepping movement is realized while the transverse reciprocating movement is realized, and the polishing mechanism 6 fixedly connected with the guide rod 18 also longitudinally moves simultaneously while the guide rod 18 longitudinally moves, so that the large-area polishing of the metal material is realized.
Through the description of the working principle, the invention can realize the transverse and longitudinal movement of the polishing mechanism 6 by only adopting one driving motor 11 matched with a corresponding mechanical structure, thereby greatly saving the cost and maintenance difficulty of the device, and the specially designed crank push rod mechanism can also greatly reduce the vibration of the device, so that the polishing quality is better.
