Abstract

[0002] A piston is a reciprocating component in an engine or compressor. The basic structure of a piston can be divided into a crown, a head, and a skirt. During manufacturing, a groove is typically machined into the piston head to meet the sealing requirements during piston operation.

[0029] like Figure 1-8 As shown, the present invention provides a piston grooving device, including a frame 1, a lifting mechanism disposed on the frame 1, a grooving mechanism slidably disposed on the lifting mechanism, a rotating clamping mechanism disposed on the frame 1 for clamping the piston, and a controller 2 disposed on the frame 1 and connected to the lifting mechanism, the grooving mechanism and the rotating clamping mechanism respectively.
[0030] In this invention, the lifting mechanism can drive the grooving mechanism to move, thereby adjusting the opening depth of the piston ring groove.
[0031] This invention provides a rotary clamping mechanism that can not only clamp the piston but also rotate it, thereby reducing the labor intensity of workers and improving the processing efficiency of the piston.
[0032] In some embodiments, a more detailed structure of the rotary clamping mechanism is provided. The rotary clamping mechanism includes a clamping mounting base 3 and a cylinder mounting base 4 mounted on the frame 1, a rotating sleeve 5 rotatably mounted in the clamping mounting base 3, a connecting shaft 6 slidably mounted in the rotating sleeve 5 and rotating synchronously with the rotating sleeve 5, a clamping seat 7 mounted on the connecting shaft 6 and in contact with the rotating sleeve 5 for clamping the piston, a cylinder A8 mounted on the cylinder mounting base 4, a connecting seat 9 with one end rotatably connected to the connecting shaft 6 and the other end connected to the output end of the cylinder A8, and a rotary drive mechanism mounted on the frame 1 and connected to the rotating sleeve 5.
[0033] In this invention, a piston is placed inside a clamping seat 7, with the piston end contacting the bottom of a limiting groove 22. A controller 2 controls the operation of cylinder A8, which in turn moves the connecting shaft 6. The connecting shaft 6 then moves the clamping seat 7. Because the rotating sleeve 5 contacts the outer wall of the clamping seat 7, and the diameter of the clamping seat 7 is slightly larger than that of the rotating sleeve 5, the clamping seat 7 undergoes plastic deformation during movement, thus fixing the piston within the clamping seat 7. Furthermore, during grooving, a rotary drive mechanism is controlled to operate, causing the rotating sleeve 5 to rotate synchronously. The rotating sleeve 5 then rotates the connecting shaft 6. Since the connecting shaft 6 is rotatably mounted within a connecting seat 9, cylinder A8 does not rotate with the connecting shaft 6. The connecting shaft 6 rotates the clamping seat 7, which in turn rotates the piston, facilitating the grooving mechanism's processing of the piston.
[0034] In some embodiments, a more detailed structure of the rotary drive mechanism is provided. The rotary drive mechanism includes a rotary mounting base 10 on the frame 1, a drive motor 11 on the rotary mounting base 10, a drive pulley 12 on the output end of the drive motor 11, a driven pulley 13 on the rotating sleeve 5, and a belt 14 between the drive pulley 12 and the driven pulley 13.
[0035] In this invention, during grooving, the controller 2 controls the drive motor 11 to run, the drive motor 11 drives the active pulley 12 to rotate, the active pulley 12 drives the driven pulley 13 to rotate via the belt 14, the driven pulley 13 drives the rotating sleeve 5 to rotate, the rotating sleeve 5 drives the connecting shaft 6 to rotate, the connecting shaft 6 drives the clamping seat 7 to rotate, and the clamping seat 7 drives the piston to rotate, thereby making the piston rotate, which facilitates the processing of the piston.
[0036] In some embodiments, a more detailed connection structure of the connecting shaft 6 and the rotating sleeve 5 is provided. The connecting shaft 6 is provided with a connecting mounting groove 15, the rotating sleeve 5 is provided with a connecting clearance groove 16, and the rotating sleeve 5 is provided with a connecting block 17 that is slidably connected to the connecting clearance groove 16.
[0037] In this utility model, the connecting block 17 is set in the connecting mounting groove 15, and the connecting block 17 can slide along the connecting clearance groove 16 when it moves. When the rotating sleeve 5 rotates, the rotating sleeve 5 drives the connecting shaft 6 to rotate through the connecting block 17, thereby facilitating the synchronous rotation of the rotating sleeve 5 and the connecting shaft 6.
[0038] In some embodiments, a more preferred structure for the connecting seat 9 is provided, the connecting seat 9 including a first connecting housing 18 disposed on the output end of the cylinder A8, a second connecting housing 19 disposed on the first connecting housing 18, a limiting block 20 disposed on the connecting shaft 6 and located within the second connecting housing 19, and a bearing 21 disposed on the second connecting housing 19 and connected to the limiting block 20 and the connecting shaft 6.
[0039] In this utility model, when the connecting shaft 6 moves, the cylinder A8 drives the first connecting housing 18 to move, the first connecting housing 18 drives the second connecting housing 19 to move, and the second connecting housing 19 drives the connecting shaft 6 and the limiting block 20 to move synchronously through the bearing 21. The limiting block 20 can facilitate the installation of the bearing 21 between the limiting block 20 and the connecting shaft 6, thereby facilitating the cylinder A8 to drive the connecting shaft 6 to move.
[0040] In this invention, when the connecting shaft 6 is rotating, since the connecting shaft 6 and the limiting block 20 are rotatably mounted on the bearing 21, the connecting shaft 6 will not drive the second connecting housing 19 to rotate during the rotation process, so that the cylinder A8 will not rotate with the connecting shaft 6, thus facilitating the processing of the piston.
[0041] In some embodiments, a more detailed structure of the clamping seat 7 is provided, wherein the clamping seat 7 is provided with a limiting groove 22 for limiting the piston.
[0042] In this utility model, the limiting groove 22 can facilitate the limiting of the piston. In addition, the clamping seat 7 is also provided with several deformation relief grooves 35, which can facilitate the plastic deformation of the clamping seat 7.
[0043] In some embodiments, a more preferred structure for the lifting mechanism is provided. The lifting mechanism includes a slotted mounting base 23 slidably disposed on the frame 1, a sliding plate 24 slidably disposed on the slotted mounting base 23, and an electric push rod 25 disposed on the slotted mounting base 23 and connected to the sliding plate 24; the slotting mechanism is mounted on the slotted mounting base 23.
[0044] In this utility model, when the lifting mechanism is in use, the controller 2 controls the electric push rod 25 to run. The electric push rod 25 pushes, the sliding plate 24 moves, and the sliding plate 24 drives the grooving mechanism to move, thereby adjusting the grooving depth of the grooving mechanism to facilitate the processing of the piston.
[0045] In some embodiments, a more detailed connection structure between the sliding plate 24 and the slotted mounting base 23 is provided. A pair of slide rails A26 are provided on the frame 1, and a slider A27 connected to the slotted mounting base 23 is slidably provided on the slide rails A26.
[0046] In this invention, the slide rail A26 is mounted on the slotted mounting base 23, and the slider A27 is slidably mounted on the slide rail A26 and connected to the sliding plate 24. The cooperation between the slide rail A26 and the slider A27 can effectively reduce the friction of the sliding plate 24 during sliding, making it easier to adjust the position of the slotting mechanism.
[0047] In some embodiments, a more detailed structure of the grooving mechanism is provided. The grooving mechanism includes an adjusting plate 28 slidably disposed on the lifting mechanism, a knife holder 29 disposed on the adjusting plate 28, a grooving knife 30 disposed on the knife holder 29, a buffer spring 31 with one end connected to the side wall of the knife holder 29 and the other end connected to the lifting mechanism, and a cylinder B32 disposed on the lifting mechanism and connected to the adjusting plate 28.
[0048] In this invention, when the piston is slotting, the controller 2 controls the cylinder B32 to operate. The cylinder B32 pushes the adjusting plate 28 to move on the sliding plate 24, so that the adjusting plate 28 compresses the buffer spring 31. The buffer spring 31 can effectively reduce the vibration of the adjusting plate 28 during movement, thereby raising the position of the grooving knife 30. The adjusting plate 28 drives the knife holder 29 to move synchronously, and the knife holder 29 drives the knife holder 29 to move, thereby adjusting the position of the grooving knife 30, so as to facilitate the grooving operation of the piston.
[0049] In some embodiments, a more detailed connection structure of the sliding plate 24 and the adjusting plate 28 is provided. The lifting mechanism is provided with a pair of slide rails B33, and the slide rails B33 are provided with a slider B34 connected to the adjusting plate 28.
[0050] In this embodiment, the slide rail B33 is disposed on the sliding plate 24, and the slider B34 is slidably mounted on the slide rail B33 and connected to the adjusting plate 28. The cooperation between the slide rail B33 and the slider B34 can effectively reduce the friction of the adjusting plate 28 when it moves, thereby improving the adjustment accuracy of the adjusting plate 28.
[0051] The controller 2 used in this invention can be an STM32F1 microcontroller. Working principle.
[0052] In use, the piston is placed in the limiting groove 22. The controller 2 controls the cylinder A8 to operate, which drives the connecting shaft 6 to move. The connecting shaft 6 drives the clamping seat 7 to move. During the movement, the clamping seat 7 comes into contact with the rotating sleeve 5, causing the clamping seat 7 to deform and thus fix the piston. Afterward, the controller 2 controls the drive motor 11 to operate, which drives the driving pulley 12 to rotate. The driving pulley 12 drives the driven pulley 13 to rotate via the belt 14. The driven pulley 13 drives the rotating sleeve 5 to rotate, which in turn drives the connecting shaft 6 to rotate. The connecting shaft 6 drives the clamping seat 7 to rotate, and the clamping seat 7 drives the piston to rotate. The piston rotates, and then the controller 2 controls the electric push rod 25 to move. The electric push rod 25 pushes the sliding plate 24 to move, and the sliding plate 24 drives the adjusting plate 28 to move. The adjusting plate 28 drives the tool holder 29 and the grooving cutter 30 to move synchronously, thereby adjusting the position of the grooving cutter 30. In addition, when the piston is being processed, the controller 2 can also control the cylinder B32 to move. The cylinder B32 pushes the adjusting plate 28 to move on the sliding plate 24. The adjusting plate 28 drives the tool holder 29 and the grooving cutter 30 to move synchronously, thereby adjusting the displacement of the grooving cutter 30. This allows the size of the piston ring groove to be adjusted, which facilitates the processing of the piston and improves the processing efficiency of the piston ring groove.
[0053] The controller 2, cylinder A8, drive motor 11, electric push rod 25, and cylinder B32 used in this utility model are existing technologies and can be purchased and used directly on the market. Therefore, the structure, circuit, and principle of the controller 2, cylinder A8, drive motor 11, electric push rod 25, and cylinder B32 will not be described in detail here.
