TECHNICAL FIELD
[0001] The utility model relates to the technical field of piston pin, and specifically relates to a compact punching equipment for machining piston pin. BACKGROUND
[0002] The piston pin is a cylindrical pin installed on the piston skirt and is an important structure connecting the piston and the connecting rod. From raw materials to finished products, it needs to go through multiple processes such as cutting, rough grinding, fine grinding, punching, slotting, and polishing. Among them, the main purpose of the punching process is to punch a through hole along the radial direction of the piston pin. The volume of the piston pin is very small, and the device used in the single punching process does not occupy too much space. However, in order to improve the degree of automation and the overall processing efficiency, it is necessary to introduce a conveying device, such as a common conveyor belt or a turntable. This will significantly increase the space occupied by the punching equipment, which is not conducive to the efficient use of space and affects the further improvement of production capacity. Based on this situation, how to reduce the space occupied by the punching equipment while ensuring the processing efficiency has become an urgent problem for relevant technical personnel. SUMMARY

[0027] Furthermore, the interior of the horizontal seat 26 is coaxially and horizontally connected to the through hole in the fixture 33 to form an inner cavity 34. A first cylinder 13 is fixedly installed at the left end of the horizontal seat 26, and a push rod 27 is fixedly installed at the output end of the first cylinder 13.

A conduit is installed at the outlet of the air pump 28, and the end of the conduit away from the air pump 28 is connected to the inner cavity 34.
[0028] Furthermore, a liquid tank 4 is fixedly installed on the upper part of the workbench 3, and a liquid delivery pipe 25 is installed at the outlet position of the liquid tank 4, with the free end of the liquid delivery pipe 25 located above the fixture 33.
[0029] Furthermore, a material box 8 is provided on the right side of the carrier 6, and a waste liquid box 7 is provided below the material box 8. The material box 8 corresponds to the position of the fixture 33.
[0030] The working principle of this compact drilling device for processing piston pins is as follows: The lower connecting plate 18 is moved left and right to a suitable position and then fixed with bolts 21 to ensure that the loading part 17 does not conflict with the discharge part 16 and the fixing device 33 when it moves up and down. At the same time, the distance between the loading part 17, the discharge part 16, and the fixing device 33 is minimized to ensure that the piston pin is smoothly transmitted between the discharge part 16 and the loading part 17, and between the loading part 17 and the fixing device 33. Vibration is then started. Vibrator 2, second cylinder 9, third cylinder 19, fourth cylinder 35, motor 31, liquid tank 4 switch, first cylinder 13, air pump 28, vibrator 2 drives vibrating plate 1 to vibrate continuously, the piston pin in vibrating plate 1 enters the feeding pipe 24 along the internal channel of vibrating plate 1, enters the feeding section 17 through the discharge section 16, under the sliding limit of the upper slide rail 15 on the upper slider 12, the output end of the second cylinder 9 pushes the lower horizontal plate 23 to move down until the feeding section 17 is located directly to the right of the fixer 33, the third cylinder 19 ...19, third cylinder 19, fourth cylinder 19, motor 31, liquid tank 4 switch, first cylinder 13, air pump 28, vibrator 2 drives vibrating plate 1 to vibrate continuously, the piston pin in vibrating plate 1 enters the feeding pipe 24 along the internal channel of vibrating plate 1, enters the feeding section 17 through the discharge section 16, enters the feeding section 17 through the discharge section 16, enters the feeding section 17 through the discharge section 17, under the sliding limit of the upper slide rail 15 on the upper slide rail 12, the The output end of cylinder 9 pushes the piston pin from the loading section 17 into the retainer 33, which fixes the piston pin. The output shaft of motor 31 drives drill bit 32 to rotate continuously. Under the sliding limit of lower slide rail 29, the output end of fourth cylinder 35 pushes lower slide block 30 closer to each other, and maintains a certain time difference in the movement of the front and rear sets of lower slide block 30. The rear drill bit 32 first drills half a hole at the predetermined position at the rear of the piston pin and then resets. Then the front drill bit 32 drills the remaining half hole at the front of the piston pin and then resets. This process... During the process, the liquid delivery pipe 25 continuously guides the coolant in the liquid tank 4 to the surface of the retainer 33 and the piston pin at its center to cool it down. The output end of the first cylinder 13 pushes the push rod 27 to the right. At the same time, the air pump 28 pressurizes the inner cavity 34 instantly through the conduit. The push of the push rod 27 and the pressurization of the air pump 28 cause the piston pin that has been drilled to "fly" out and fall into the material box 8. The coolant on the surface of the piston pin leaks into the waste liquid box 7. The above process continues, and the staff can empty the material box 8 periodically.
[0031] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
