Description

Technical Field

[0001] The utility model relates to the technical field of piston pin processing, in particular to a piston pin processing feeding device. Background Art

[0002] The piston pin is a cylindrical pin installed on the piston skirt. Its main function is to connect the piston and the connecting rod. The middle part of the piston pin passes through the small head hole of the connecting rod, so that the small head of the connecting rod can drive the piston to move together. This design transmits the gas force borne by the piston to the connecting rod, or transmits the movement of the connecting rod to the piston. The piston pin is usually made of high-quality alloy steel and may be designed to be hollow to reduce weight. Because the piston pin is subjected to a large periodic impact load under high temperature conditions and the swing angle in the pin hole is not large, it is difficult to form a lubricating oil film, so it must have sufficient rigidity and strength. In order to improve the efficiency of piston pin processing, the piston pin is often automatically transported to the processing position during piston pin processing. In the prior art, since most piston pins are cylindrical, the piston pin is directly placed on an inclined guide rail when feeding the piston pin. Under the action of gravity, the piston pin is rolled along the feeding guide rail to the processing position. However, the spacing between the piston pins cannot be determined during the transportation process. During the feeding process, the piston pins are prone to collision, resulting in deviation in the feeding position of the piston pin, which affects the efficiency of piston pin processing.

At this time, the right movement of the piston pin is not blocked, and the piston pin moves to the right with the feeding frame plate 84. When the feeding frame plate 84 moves downward, under the top pressure of the top plate 81, the piston pin moves downward and enters between the two placement grooves 7 corresponding to the longitudinal position. As the feeding frame plate 84 continues to reciprocate, the piston pin inside the placement groove 7 is driven to move to the placement groove 7 adjacent to the right, so that the piston pin moves to the right. As the piston pin is continuously discharged from the discharge port of the storage shell 1, the fixed-distance feeding of the piston pin is realized, and the feeding is stable. The mechanism 8 also includes a top plate 81, a guide column 82 and a spring 83. The guide columns 82 are respectively vertically slidably connected to the sliding holes on the upper surface of the feeding plate 2. A top plate 81 is arranged between the upper ends of the guide columns 82. The outer arc surfaces of the guide columns 82 are movably sleeved with springs 83. The lower ends of the springs 83 are respectively fixedly connected to the disks at the lower ends of the guide columns 82. The upper ends of the springs 83 are fixedly connected to the feeding plate 2. Under the elastic force of the springs 83, the vertical position of the top plate 81 is limited to limit the upward movement of the piston pin in the feeding plate 2.

The input end of the single-chip microcomputer 10 is electrically connected to an external power supply. The stable feeding mechanism 8 also includes a rotating plate 86, a slide groove 87 and a motor 89. The motor 89 is respectively Set at the front and rear ends of the base 5, the output shaft of the motor 89 passes through the circular hole in the middle of the return frame 88 and is provided with a rotating plate 86, the surface of the rotating plate 86 is provided with a slide groove 87, the connecting column 85 is slidably connected with the slide groove 87, the input end of the motor 89 is electrically connected to the output end of the single-chip microcomputer 10, the motor 89 is started, and the output shaft of the motor 89 drives the rotating plate 86 to rotate clockwise, so that the connecting column 85 slides in the slide groove 87, the right inner wall of the material storage shell 1 is respectively provided with an inclined plate 3, the inclined plate 3 gradually tilts downward from right to left, and the left inner wall of the material storage shell 1 is respectively provided with an inclined plate 2 4, the inclined plate 2 4 gradually tilts downward from left to right, the inclined plate 1 3 and the inclined plate 2 4 are staggered up and down, and the moving trajectory of the piston pin is guided by the cooperation of the inclined plate 1 3 and the inclined plate 2 4.Avoid excessive accumulation of piston pins that may affect material discharge.

[0022] The working principle of a piston pin processing and feeding device provided by the utility model is as follows: during the processing of the piston pin, the piston pin is placed inside the material storage shell 1, and the cooperation of the inclined plate 1 3 and the inclined plate 2 4 is used to guide the moving trajectory of the piston pin to avoid excessive accumulation of piston pins affecting the discharge, and to ensure that the piston pin is affected by gravity and normally enters the feeding plate 2 from the discharge port at the lower end of the material storage shell 1. After the piston pin enters the feeding plate 2, the top plate 81 is used to limit the upward movement of the piston pin, so that the cross plate 6 blocks the rightward movement of the piston pin, and the motor 89 is started by the single-chip microcomputer 10. The output shaft of the motor 89 drives the rotating plate 86 to rotate clockwise, so that the connecting column 85 slides in the slide groove 87, so that the connecting column 85 drives the feeding frame plate 84 to move, and at the same time, the connecting column 85 slides in the return groove of the return frame 88, and the moving path of the feeding frame plate 84 is guided, so that the feeding frame plate 84 moves along the return trajectory. The piston pin is moved to the right with the feeding frame plate 84. When the feeding frame plate 84 moves downward, the piston pin moves downward and enters between the two placement grooves 7 corresponding to the longitudinal position. As the feeding frame plate 84 moves back and forth, the piston pin enters the groove of the feeding frame plate 84, limiting the left and right position of the piston pin. When the piston pin completely enters the groove, as the feeding frame plate 84 continues to move upward, the elastic force of the spring 83 is overcome, so that the top plate 81 moves upward, and at the same time, the piston pin is driven to move upward to the upper side of the cross plate 6. At this time, the right movement of the piston pin is not blocked, and the piston pin moves to the right with the feeding frame plate 84. When the feeding frame plate 84 moves downward, under the top pressure of the top plate 81, the piston pin moves downward and enters between the two placement grooves 7 corresponding to the longitudinal position. As the feeding frame plate 84 continues to reciprocate, the piston pin inside the placement groove 7 is driven to move to the placement groove 7 adjacent to the right, so that the piston pin continues to move to the right. As the piston pin is continuously discharged from the discharge port of the storage shell 1, the fixed-distance feeding of the piston pin is realized.
