[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above - mentioned terms in the present invention can be understood according to specific situations.

[0044] Combined with Figures 1 to 7 As shown, the present invention provides an automatic piston oil ring installation device, which can automatically assemble the piston oil ring into the annular groove of the piston, without manual installation, which can not only save labor costs, but also effectively improve work efficiency. Among them, the automatic piston oil ring installation device of the present invention mainly includes a base 11, a top plate 21, a ring support cylinder 34, a lifting mechanism, a ring pressing mechanism and other related structural components.

[0045] Combined with Figure 1 and Figure 2 As shown, a first opening is provided at the center of the base 11, and a ring support cylinder 34 is arranged inside the first opening. A plurality of pneumatic grippers 341 are equally spaced at the top of the ring support cylinder 34. The ring support cylinder 34 can drive the pneumatic grippers 341 to move radially along the ring support cylinder 34, so as to be able to expand the piston oil ring outward, so that the piston oil ring can be assembled into the annular groove of the piston later.

[0046] Combined with Figures 1 to 3As shown, the support ring cylinder 34 is equipped with a lifting mechanism, which can drive the support ring cylinder 34 to rise and fall. The lifting mechanism mainly includes structural components such as a cylinder fixing seat 31, a lifting cylinder 32 and a connecting plate 33. Among them, the cylinder fixing seat 31 is arranged on one side of the base 11, the cylinder body end of the lifting cylinder 32 is fixedly connected to the cylinder fixing seat 31, and the telescopic end of the lifting cylinder 32 is fixedly connected to a connecting plate 33 with an L-shaped outer contour, and the support ring cylinder 34 is arranged on the top of the connecting plate 33. When the support ring cylinder 34 drives the pneumatic clamp 341 to open the piston oil ring outward, wait for the piston to fall into place, the telescopic end of the lifting cylinder 32 is retracted, and the connecting plate 33 drives the support ring cylinder 34 to descend as a whole, and the pneumatic clamp 341 is separated from the piston oil ring, and the piston oil ring inertia retracts and is embedded in the annular groove of the piston to complete the assembly.

[0047] Combination Figure 1 As shown, two symmetrically arranged support shafts 12 are provided on the base 11. The two support shafts 12 are provided on both sides of the first opening, and the top ends of the two support shafts 12 are connected by a support plate 14. A floating spring 13 is provided on each support shaft 12, and the floating spring 13 can perform a reset operation after the piston oil ring is assembled. The bottom end of the floating spring 13 is connected to the top of the base 11, and the top end of the floating spring 13 is connected to the bottom of the support plate 14. The support shaft 12 can drive the support plate 14 to move longitudinally relative to the base 11 under the elastic force of the floating spring 13. At the same time, combined with Figures 1 to 3 As shown, the bottom end of the support shaft 12 passes through the base 11, and a limiting bolt 121 is provided on the bottom plate of the base 11 and opposite to the bottom end of the support shaft 12. The limiting bolt 121 can limit the downward movement of the support shaft 12 to avoid excessive downward pressure that damages the device.

[0048] Combination Figure 6 As shown, the top end of the support shaft 12 is connected to the support plate 14 by bolts. The support plate 14 is located directly above the first opening of the base 11 and is mainly used to carry the floating block 15. Figure 1 As shown, a floating block 15 is arranged at the middle position of the top of the support plate 14, and the peripheral side wall of the floating block 15 is provided with load blocks 151 arranged at equal intervals, and the piston oil ring can be pushed to the top of the load block 151 along the material channel 23, waiting for subsequent operations such as ring support. Among them, a groove is opened on the top of the load block 151, which can limit the position of the piston oil ring and facilitate the subsequent ring support operation.

[0049] The floating block 15 is driven by the pressure from the piston to drive the support plate 14 to descend, and the floating spring 13 is contracted by the pressure. At the same time, the support shaft 12 descends and is limited by the limit bolt 121. After the piston oil ring is assembled, the piston moves up, and the floating spring 13 rebounds and resets by itself. The support plate 14 drives the floating block 15 back to the initial position. The whole process has a high degree of automation, which can effectively improve the assembly efficiency.

[0050] Combined with Figure 6 and Figure 7 As shown, the pneumatic gripper 341 of the support ring cylinder 34 and the load block 151 are arranged at intervals around the floating block 15, and there will be no interference between them. The pneumatic gripper 341 can smoothly open the piston oil ring.

[0051] Combined with Figure 1 and Figure 2 As shown, a top plate 21 is arranged above the base 11. It should be noted that the top plate 21 is fixedly supported by four support columns 22 arranged at its corners with other platen (not shown in the figure), rather than being fixed to the base 11.

[0052] Combined with Figure 1 As shown, a second opening is provided in the middle position of the top plate 21, and the floating block 15 is located within the second opening. Among them, a stop block is provided at the side wall of the second opening of the top plate 21 and opposite to the load block 151. The stop block can prevent the piston oil ring from following the pneumatic gripper 341 and descending. A material channel 23 is provided at the top of the top plate 21, and limiting baffles 24 are arranged on both sides of the material channel 23. Among them, the piston oil ring is pushed by a pushing mechanism (not shown in the figure) from the upper-level mechanism through the material channel 23 to the second opening of the top plate 21, that is, onto the load block 151 of the floating block 15 for storage. At the same time, the limiting baffles 24 can relatively limit the size of the pushed piston oil ring. Combined with Figure 1 and Figure 5 As shown, a proximity switch 25 is also provided on the top plate 21. The proximity switch 25 can be used to detect whether the pneumatic gripper 341 has fully opened the piston oil ring.

[0053] Combined with Figure 5 As shown, a ring pressing mechanism is arranged inside the top plate 21. The ring pressing mechanism can abut against the piston oil ring to prevent the piston oil ring from popping out and falling off during the opening process, so as to ensure the smooth progress of subsequent assembly operations. The ring pressing mechanism mainly includes structural components such as a push-pull cylinder 41, a push plate 42, a rack 43, a gear disk 44, and a pressing block 45.

[0054] Combined with Figure 5As shown in the figure, the cylinder body end of the push-pull cylinder 41 is fixedly connected to the bottom of the top plate 21, the telescopic end of the push-pull cylinder 41 is fixedly connected to the push plate 42, and a rack 43 is arranged on the push plate 42. The gear disk 44 is arranged at the edge of the second opening of the top plate 21, and the gear disk 44 can rotate relative to the top plate 21, and the gear disk 44 meshes with the rack 43. An annular plate is arranged at the inner ring edge of the gear disk 44, and strip-shaped holes are formed at the relative positions of the annular plate and the top plate 21. A connecting shaft is arranged at the bottom of the pressing block 45, the connecting shaft is inserted into the strip-shaped hole, and the pressing block 45 can slide along the strip-shaped hole through the connecting shaft. When the gear disk 44 rotates, the pressing block 45 can extend or retract. When the pressing block 45 slides and extends, it can abut against the piston oil ring, so as to prevent the piston oil ring from popping out and falling off during the opening process.

[0055] Combined with Figure 5 As shown in the figure, when the piston oil ring has not been positioned at the top of the load block 151, the strip-shaped holes on the top plate 21 coincide with the strip-shaped holes on the annular plate. At this time, the pressing block 45 does not extend; when the piston oil ring is positioned at the top of the load block 151, the telescopic end of the push-pull cylinder 41 retracts, and the rack 43 arranged on the push plate 42 drives the gear disk 44 to rotate clockwise. At this time, the strip-shaped holes of the top plate 21 and the annular plate are misaligned, the connecting shaft moves along the strip-shaped hole towards the center of the second opening, and the pressing block 45 extends and is located above the piston oil ring, realizing the shielding and pressing of the piston oil ring to prevent the piston oil ring from popping out and falling off during the opening process.

[0056] The working process of the piston oil ring automatic installation device of the present utility model is as follows:

[0057] First of all, the piston oil ring is pushed to the second opening of the top plate 21 through the pushing mechanism (not shown in the figure) via the material channel 23, that is, stored at the top of the load block 151 of the floating block 15; secondly, the push-pull cylinder 41 drives the gear disk 44 to rotate clockwise, and the pressing block 45 extends and moves above the piston oil ring to prevent the piston oil ring from popping out during the subsequent opening process; the ring expanding cylinder 34 drives the pneumatic gripper 341 to expand the piston oil ring outwards, and the piston oil ring leaves the load block 151; after the proximity switch 25 detects that the piston oil ring is expanded, the piston presses down the floating block 15 and moves to the preset position; the lifting cylinder 32 drives the connecting plate 33 to descend, driving the ring expanding cylinder 34 to descend as a whole. Due to the block of the stopper, the piston oil ring is separated from the pneumatic gripper 341, and the piston oil ring retracts by inertia and automatically embeds into the annular groove of the piston to complete the installation.

[0058] Combined with Figures 1 to 7As shown in the figure, the present utility model provides an automatic piston oil ring installation device. By adding a ring pressing mechanism, it can prevent the piston oil ring from popping out and falling off during the expansion process. At the same time, by adding a proximity switch 25, it can detect whether the piston oil ring is fully expanded. By adding a limit bolt 121 to the base 11, it can prevent damage to the device caused by excessive downward pressure of the support shaft 12. By adding a floating spring 13, the piston oil ring can automatically reset after assembly. At the same time, the degree of automation of the entire assembly process is relatively high, which can effectively improve the assembly efficiency. The automatic piston oil ring installation device of the present utility model can automatically install the piston oil ring into the annular groove of the piston without manual installation, which can not only effectively improve the working efficiency, save a certain amount of labor costs, but also avoid damage to the piston oil ring caused by manual installation.

[0059] Of course, the above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model and should be protected by the present utility model.
