Description

Technical Field

[0001] This utility model relates to the field of piston machining technology, and in particular to a composite boring and milling lathe based on piston machining. Background Technology

[0002] As the "heart" of an internal combustion engine, the piston's machining quality directly determines the engine's performance, fuel consumption, noise, and service life. A piston is a typical part with a complex shape and extremely high precision requirements. Its structural features include irregularly shaped outer cylindrical profiles, annular grooves, pin holes, internal cavities, and complex top designs. Traditionally, machining a finished piston requires sequential processing on multiple specialized machine tools, such as rough and finish turning the outer diameter on a lathe, milling the annular grooves on a milling machine, drilling the pin holes on a drilling machine, and machining the internal cavity on a specialized machine tool.

[0003] Chinese Patent Publication No. CN210703582U discloses a piston rod positioning fixture and a boring and milling machine using the fixture. The fixture includes a support plate and two sets of clamping components welded to the upper surface of the support plate for clamping the piston rod. Each set of clamping components has a movable clamping plate rotatably connected to its sidewall and lower end via a pin. Each clamping component has an insertion groove on its upper surface, and a fixing bolt is rotatably disposed inside the insertion groove via a pin. A threaded cap and a washer are threadedly connected to the end of the fixing bolt near the movable clamping plate. The upper surface of the movable clamping plate has a groove for the fixing bolt to be inserted. The piston rod is fixedly clamped onto the clamping components by the clamping force of the threaded pair, achieving a stable clamping effect on the piston rod.

[0004] However, in actual use, the device generates a large amount of iron filings when boring and milling the piston. These filings fall onto the top of the sliding track, and over time, they can affect the position adjustment of the clamping components, thus affecting the boring and milling operation.

[0031] Working Principle: This utility model discloses a composite boring and milling lathe based on piston machining. The workpiece is placed on top of two support plates 17. Then, the pressure plate 24 is moved so that the top and bottom of the workpiece are in contact with the inner side of the adjacent limiting groove 28. Then, the nut 26 is put on and tightened by the operating rod 27. The nut 26 presses and fixes the pressure plate 24, which fixes the workpiece. Then, the support plate 17 is moved, which drives the workpiece to move horizontally. The support plate 17 drives the second slider 19 to move through the second connecting rod 18 and the third connecting rod 31. The second slider 19 moves in the inner cavity of the second slide groove 20. After the workpiece moves to the front side of the milling cutter 6, the rocker wheel 23 is rotated. The rocker wheel 23 drives the first threaded rod 22 to rotate. The first threaded rod 22 rotates to insert into the adjacent limiting hole 30, thereby fixing the position of the support plate 17 and thus fixing the position of the workpiece.

[0032] Then, start the drive motor 4, which drives the milling cutter 6 to rotate. Start the adjustment motor 12, which drives the lead screw 11 to rotate in the inner cavity of the first screw hole 10. The movable plate 9 moves forward under the action of the thread. The movable plate 9 drives the mounting base 3 to move through the first connecting rod 7. The first connecting rod 7 drives the first slider 14 to move in the inner cavity of the first slide groove 15. The mounting base 3 drives the milling cutter 6 to move towards the workpiece. The milling cutter 6 performs boring and milling on the workpiece.

[0033] The device, through the setting of the second slider 19 and the second slide 20, can adjust the horizontal position of the workpiece, thereby facilitating the boring and milling operation of the workpiece. Furthermore, the second slide 20 is set on the side wall of the clamping worktable 16 to prevent iron chips from falling into the second slide 20 during the boring and milling process, thereby ensuring the normal operation of the second slide 20 and thus ensuring the normal progress of the boring and milling operation.

[0034] By setting the first threaded rod 22 and the second threaded hole 21, after the horizontal position of the workpiece is adjusted, the first threaded rod 22 is rotated by the rocker wheel 23 and inserted into the inner cavity of the adjacent limiting hole 30, thereby fixing the position of the workpiece and facilitating the milling cutter 6 to perform boring and milling on the workpiece.
