Description

Technical Field

[0001] The utility model relates to the technical field of piston processing, and more specifically to an automatic boring device for an engine piston. Background Art

[0002] The engine piston is an important component in the internal combustion engine. It is a cylindrical metal component, usually made of materials such as aluminum alloy or cast iron. The piston is located in the cylinder of the engine, and its main function is to convert the gas pressure generated by the combustion of fuel into mechanical energy. When the mixed gas burns in the cylinder, high-temperature and high-pressure gas is generated, which pushes the piston to make reciprocating linear motion in the cylinder. The piston is connected to the connecting rod through the piston pin, and the connecting rod is connected to the crankshaft. In this way, the reciprocating motion of the piston is converted into the rotational motion of the crankshaft, thereby driving the car or other mechanical operation. Usually, the piston needs to be bored to improve accuracy, optimize stress distribution and meet different usage requirements.

During the pre-drilling and reaming process, more debris is often generated in the hole of the piston.

[0034] In this embodiment, through the arrangement of the piston 28, the staff can place the piston 28 into the clamping groove 29. At this time, the output end of the electric push rod 10 moves downward and drives the clamping block 11 to clamp the piston 28. Then the output ends of the two fifth drive motors 27 extend to drive the clamping head 22 to move and clamp the piston 28 through the two clamping heads 22. The piston 28 is clamped both horizontally and vertically to ensure the stability of the piston 28 during processing.

[0036] In this embodiment, by providing the bearing 34 , when the threaded rod 19 rotates inside the bearing 34 , the bearing 34 can ensure the stability of the rotation of the threaded rod 19 .

[0037] Specifically, the driving component also includes: two fixed rods 17, both of which are fixedly connected to the inner bottom wall of the processing seat 12, one end of the fixed rod 17 is fixedly connected to the inner top wall of the processing seat 12, and two circular holes are opened on the top surface of the movable plate 23, and the movable plate 23 is movably connected to the fixed rod 17 through the circular holes.

[0038] In this embodiment, by setting up the fourth drive motor 18, the staff can start the set fourth drive motor 18, and the output end of the fourth drive motor 18 drives the threaded rod 19 to rotate. Since the movable plate 23 is threadedly connected to the threaded rod 19, and the two fixed rods 17 limit the movable plate 23, the movable plate 23 moves in a straight line and drives the movable block 2 to move upward synchronously until the movable block 2 enters the interior of the top hole 30 and is flush with the processing seat 12. At this time, the slider of the third electric slide 33 drives the collecting bin 31 to move until the collecting bin 31 is fitted with the piston 28, and then the wind force output by the fan 21 will enter the interior of the air outlet 26 through the connecting pipe 24, and the wind blown out by the air outlet 26 can blow the debris generated in the hole during pre-drilling and reaming of the piston 28 to the interior of the collecting bin 31 for collection, and the debris can be cleaned.

[0039] The working principle and use process of the utility model are as follows: when in use, the staff can put the piston 28 into the clamping groove 29. At this time, the output end of the electric push rod 10 moves downward and drives the clamping block 11 to clamp the piston 28. Then the output ends of the two fifth drive motors 27 extend to drive the clamping heads 22 to move and clamp the piston 28 through the two clamping heads 22. The piston 28 is clamped both horizontally and vertically to ensure the stability of the piston 28 during processing.

[0040] Then start the second electric slide 16, and the movement of the slider of the second electric slide 16 drives the moving seat 13 and the processing seat 12 to move until the piston 28 corresponds to the drill position of the second drive motor 8. At this time, the second electric slide 16 stops, and the sliders of two of the first electric slides 5 drive the two second drive motors 8 to move, so that the output end of the second drive motor 8 drives the drill bit to pre-drill the piston 28.

[0041] After the pre-drilling is completed, the slider of the second electric slide 16 drives the processing seat 12 to continue to move through the moving seat 13 until the position of the hole pre-drilled by the piston 28 corresponds to the position of the reamer of the third drive motor 14, and then the second electric slide 16 stops. The slider of one of the first electric slides 5 drives the third drive motor 14 to move, and drives the reamer through the output end of the third drive motor 14 to reamer the hole pre-drilled on the piston 28.

[0042] After the hole expansion is completed, the staff can start the fourth drive motor 18, and the output end of the fourth drive motor 18 drives the threaded rod 19 to rotate. Since the movable plate 23 is threadedly connected with the threaded rod 19, and the two fixed rods 17 limit the movable plate 23, the movable plate 23 moves linearly and drives the movable block 2 to move upward synchronously until the movable block 2 enters the inside of the top hole 30 and is flush with the processing seat 12. At this time, the collection bin 31 and the air outlet 26 also move synchronously to the processing seat 12. Then the slider of the third electric slide 33 drives the collection bin 31 to move until the collection bin 31 fits with the piston 28. At this time, the feed port of the collection bin 31 corresponds to the hole position after the piston 28 is expanded, and then the wind output by the fan 21 will enter the inside of the air outlet 26 through the connecting pipe 24, that is, the wind blown by the air outlet 26 can blow the debris generated in the hole during the pre-drilling and expansion of the piston 28 to the inside of the collection bin 31 for collection, and the debris can be cleaned.

[0043] After the cleaning is completed, the slider of one of the first electric slides 5 drives the first drive motor 6 to move, and the boring tool 7 is driven by the output end of the first drive motor 6 to bore the hole after the piston 28 is expanded. Compared with the prior art, when processing the piston 28, the present application can timely clean the debris left inside the hole of the piston 28 during pre-drilling and expansion, so as to avoid the debris affecting the accuracy of boring.
