Description

Technical Field

[0001] This utility model relates to the technical field of piston rings, specifically to a piston ring finishing machine. Background Technology

[0002] Piston rings are critical components installed in the piston grooves of internal combustion engines, directly affecting engine performance, efficiency, and lifespan. By tightly fitting against the cylinder wall, piston rings form a dynamic seal, preventing high-temperature, high-pressure gases (energy generated by combustion) from leaking into the crankcase, ensuring maximum combustion efficiency. Poor sealing allows unburned gases (blow-by gases) to enter the crankcase, contaminating the engine oil, reducing lubrication, and increasing emissions. As the piston moves downwards, piston rings scrape excess oil from the cylinder wall, preventing it from entering the combustion chamber and being burned. Piston rings also form a uniform oil film on the cylinder wall surface, reducing direct friction between the piston and cylinder and minimizing wear.

[0003] When performing the cuff elasticity test on piston rings, several piston rings need to be stacked on the equipment and tested sequentially. The cuffs of these piston rings must be in the same position to facilitate testing. Similarly, during piston ring assembly, the cuffs of the piston rings on the piston need to be staggered according to assembly requirements. When using automated assembly equipment, the cuffs of the piston rings also need to be in the same position to facilitate automatic assembly. Existing automatic cuff alignment equipment is costly and requires transferring the piston rings, affecting work efficiency. Therefore, a piston ring sorting machine needs to be designed. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issues of high cost and the need to transfer piston rings, which affect efficiency, in existing automatic opening alignment equipment.

[0005] To achieve the above objectives, this utility model provides a piston ring finishing machine, comprising: a mounting bracket, a horizontal rubber roller mounted on the mounting bracket via a pair of bearings, a motor drivenly connected to the end of the rubber roller, a pair of mounting units on the symmetrical mounting bracket, and a support tube unit whose ends are detachably mounted on the pair of mounting units.

[0006] The support tube unit includes a support tube that is parallel to the rubber roller when assembled on the mounting unit and a positioning clip that can be detached and assembled on the outer wall of the support tube of the same length. The rubber roller contacts the bottom side of the piston ring to drive the piston ring to rotate.

[0007] Preferably, the end of the support tube is recessed and has several notches evenly distributed along the circumferential direction;

[0008] One end of the positioning strip has a protruding locking part that can be inserted into the corresponding notch, and the other end of the positioning strip is equipped with a locking mechanism that is adapted to the corresponding notch.

[0009] The latching mechanism includes a latching member that is slidably connected to the positioning strip along the length of the positioning strip and matches the corresponding notch, and an elastic member for pushing the latching member closer to the latching part.

[0010] Preferably, the snap-fit ​​mechanism further includes at least one pair of first guide sleeves assembled on the end of the positioning clip, at least one pair of second guide sleeves assembled on the snap-fit ​​member, and at least one pair of guide pins corresponding to the second guide sleeves, wherein the second guide sleeve is located on the side of the first guide sleeve away from the snap-fit ​​portion;

[0011] The guide bolt slides through the corresponding first guide sleeve and second guide sleeve, and the elastic element is at least one spring sleeved on the corresponding guide bolt, with the two ends of the spring abutting against the ends of the first guide sleeve and the guide bolt, respectively.

[0012] Preferably, the snap-fit ​​component is provided with a pull ring portion.

[0013] Preferably, the installation unit includes a mounting base fixedly mounted on a mounting bracket and having a recessed mounting groove for accommodating the end of the support tube, and a limiting mechanism mounted on the mounting base that can press against the top of the support tube.

[0016] Preferably, the output shaft of the motor is connected to the end of the rubber roller via a belt and a pair of synchronous pulleys.

[0017] According to the above technical solution, the piston ring finishing machine provided by this utility model has the following beneficial effects during use:

[0018] Firstly, the positioning clip can be detached and installed on the support tube, which not only avoids the need to customize a large number of tubes to fit this equipment, reducing costs; but also eliminates the need for piston rings to be transferred between the support tube and the customized tube during use, thus improving work efficiency.

[0019] Secondly, the positioning clips can also be reused. After the positioning clips are removed from the support tube, the support tube can also be used in the previous process, which can reduce the pipe input cost of the entire production line.

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-4 As shown, a piston ring finishing machine includes: a mounting bracket 1, a horizontal rubber roller 2 mounted on the mounting bracket 1 via a pair of bearings, a motor 3 drivenly connected to the end of the rubber roller 2, a pair of mounting units on the mounting bracket 1 in a symmetrical state, and a support tube unit whose two ends are detachably mounted on the pair of mounting units.

[0031] The support tube unit includes a support tube 4 that is parallel to the rubber roller 2 when assembled on the mounting unit, and a positioning clip 5 that can be detached and assembled on the outer wall of the support tube 4 at the same length. The rubber roller 2 contacts the bottom side of the piston ring to drive the piston ring to rotate.

[0032] In the above technical solution, when used in the previous process, the positioning clip 5 on the support tube 4 can be removed. Because the positioning clip 5 will be scratched by long-term contact with the inner wall of the piston ring, several piston rings are sleeved on the support tube 4 to facilitate the transfer of piston rings between processes, and play the role of temporarily storing and transferring piston rings.

[0033] When automatically assembling or testing the elasticity of the piston ring opening, it is necessary to determine the opening direction of the piston ring. At this time, the positioning clip 5 can be assembled on the bottom of the support tube 4, and then the support tube 4 can be rotated so that the positioning clip 5 rotates to the top. Because there is space between the inner wall of the piston ring and the bottom of the support tube 4, it is convenient to assemble the positioning clip 5. After the positioning clip 5 is assembled on the support tube 4, the two ends of the support tube 4 can be assembled on a pair of mounting units. At this time, the piston ring will tilt due to the pressure of the rubber roller 2. Only when the rubber roller 2 rotates can it drive the piston ring to rotate.

[0034] Motor 3 drives rubber roller 2 to rotate, and rubber roller 2 will drive several piston rings sleeved on support tube 4 to rotate. When the opening of the piston ring rotates to the top, it will be stuck in the positioning strip 5 until the opening of several piston rings is stuck in the positioning strip 5, thus completing the opening arrangement of several piston rings to facilitate the next processing step.

[0035] Using rubber roller 2 can increase the friction between it and the piston ring, which is beneficial to drive the piston ring to rotate when the rubber roller 2 rotates. The figure only shows two states of the piston ring. In actual use, several piston rings will be fitted onto the support tube 4 in sequence.

[0036] The positioning clip 5 can be detached and installed on the support tube 4, which not only avoids the need to customize a large number of tubes to match this equipment, reducing costs; but also eliminates the need for piston rings to be transferred between the support tube 4 and the customized tubes during use, thus improving work efficiency; the positioning clip 5 can also be reused; after the positioning clip 5 is removed from the support tube 4, the support tube 4 can also be used in the previous process, which can reduce the tube input cost of the entire production line.

[0037] In a preferred embodiment of the present invention, the end of the support tube 4 is recessed and provided with a plurality of notches 6 evenly distributed along the circumferential direction.

[0038] One end of the positioning strip 5 is provided with a snap-fit ​​part 7 that can be inserted into the corresponding notch 6, and the other end of the positioning strip 5 is equipped with a snap-fit ​​mechanism that is adapted to the corresponding notch 6.

[0039] The latching mechanism includes a latching member 22 that is slidably connected to the positioning strip 5 along the length of the positioning strip 5 and matches the corresponding notch 6, and an elastic member for pushing the latching member 22 closer to the latching part 7 to slide.

[0040] In the above technical solution, when the positioning clip 5 needs to be assembled on the support tube 4, since the support tube 4 is fitted with several piston rings, the support tube 4 can be rotated so that one of the notches 6 is set downwards. After the snap-fit ​​part 7 is snapped into the notch 6 at one end of the support tube 4, the snap-fit ​​part 22 is pulled to align it with the notch 6 at the other end of the support tube 4. Under the action of the elastic element, the snap-fit ​​part 22 will snap into the corresponding notch 6. At this time, the positioning clip 5 is assembled on the support tube 4. The operation is simple and convenient.

[0041] In a preferred embodiment of the present invention, the snap-fit ​​mechanism further includes at least one pair of first guide sleeves 8 assembled on the end of the positioning clip 5, at least one pair of second guide sleeves 9 assembled on the snap-fit ​​member 22, and at least one pair of guide bolts 10 corresponding to the second guide sleeves 9, wherein the second guide sleeves 9 are located on the side of the first guide sleeves 8 away from the snap-fit ​​part 7.

[0042] The guide bolt 10 slides through the corresponding first guide sleeve 8 and second guide sleeve 9. The elastic element is at least one spring sleeved on the corresponding guide bolt 10, and the two ends of the spring abut against the ends of the first guide sleeve 8 and the guide bolt 10, respectively.

[0043] In the above technical solution, after the snap-fit ​​part 7 snaps into the notch part 6, the snap-fit ​​part 22 is pulled away from the positioning clip 5, the distance between the first guide sleeve 8 and the second guide sleeve 9 increases, the spring is further compressed, and when the snap-fit ​​part 22 moves to the notch part 6, it is released. The spring will push the guide bolt 10 to slide close to the snap-fit ​​part 7 on the first guide sleeve 8, thereby driving the snap-fit ​​part 22 to slide into the notch part 6.

[0044] In a preferred embodiment of the present invention, the snap-fit ​​member 22 is provided with a pull ring portion 11.

[0045] In the above technical solution, the pull ring part 11 facilitates the operator to pull the locking part 7.

[0046] In a preferred embodiment of the present invention, the installation unit includes a mounting seat 13 fixedly mounted on the mounting bracket 1 and having a recessed mounting groove 12 for accommodating the end of the support tube 4, and a limiting mechanism mounted on the mounting seat 13 that can press against the top of the support tube 4. The inner wall of the mounting groove 12 is fitted with a locking block 14 that matches the notch 6.

[0047] In the above technical solution, since the end of the support tube 4 is provided with several notches 6, after the positioning clip 5 is assembled in one of the notches 6, the clip 14 can be inserted into the remaining notch 6, and the top of the support tube 4 can be pressed by the limiting mechanism to fix the end of the support tube 4.

[0048] In a preferred embodiment of the present invention, the limiting mechanism includes a limiting arm 16 mounted on the mounting base 13 via a first hinge seat 15, a limiting member 17 mounted on the limiting arm 16 and capable of contacting the top of the support tube 4, a locking arm 18 mounted on the side of the mounting base 13 away from the first hinge seat 15 via a second hinge seat, and a torsion spring 19 mounted on the second hinge seat for pushing the locking arm 18 to rotate upward.

[0049] The end of the limiting arm 16 away from the first hinge seat 15 is provided with a connecting part 20, and the end of the snap-fit ​​arm 18 away from the second hinge seat is provided with a pressing part 21 that can press against the connecting part 20.

[0050] In the above technical solution, after the end of the support tube 4 is placed into the mounting groove 12, the snap-fit ​​arm 18 is rotated away from the limiting arm 16, and then the limiting arm 16 is rotated so that the limiting member 17 contacts the top of the support tube 4. At this time, the limiting arm 16 is released, and the pressing part 21 on the limiting arm 16 will press against the connecting part 20, so that the limiting member 17 cannot be separated from the top of the support tube 4.

[0051] In a preferred embodiment of this utility model, the output shaft of the motor 3 is connected to the end of the rubber roller 2 via a belt and a pair of synchronous pulleys.
