Description

Technical Field

[0001] This invention belongs to the field of engine technology, and in particular relates to a variable diameter adaptive piston assembly device. Background Technology

[0002] The piston assembly is one of the most important moving parts of an engine. It consists of a piston and piston rings. Piston rings are metal rings embedded in piston ring grooves. After the piston and piston rings are assembled and installed into the cylinder liner, the piston rings and the inner wall of the cylinder liner form a sealed space. The outer diameter of the piston rings in their free state is larger than the inner diameter of the cylinder liner. The piston with piston rings needs to be pressed tightly before it can be installed into the cylinder liner. Current assembly methods often involve using a sheet metal band to tightly bind the piston assembly before installing it into the cylinder liner. This method is only suitable for assembling pistons for engines with a single cylinder diameter, lacking universal assembly capability. Furthermore, this assembly process needs to be repeated for piston assemblies of different engine sizes, making the assembly process complex and posing safety hazards. Summary of the Invention

[0009] Furthermore, the outer circumferential surface of the support ring is provided with two annular grooves, and the first rotating disk and the second rotating disk are respectively disposed in the two annular grooves.

[0010] Furthermore, the telescopic assembly includes a telescopic rod, a guide plate, a limiting block, and a spring; one end of the telescopic rod engages with the guide hole of the first rotating disk through the guide rod; the other end passes through the support ring and is hinged to the middle of the guide plate;

[0011] The upper part of the guide plate is connected to the support ring by a spring;

[0012] The lower part of the guide plate is connected to the telescopic rod through a limiting block. The guide plate and the limiting block are fixedly connected by a pin, and the limiting block and the guide plate are in contact.

[0013] Furthermore, the guide hole of the first rotating disk is a variable diameter trajectory hole, and rotating the first rotating disk can realize the forward and backward movement of the telescopic rod.

[0014] Furthermore, the clamping assembly includes a clamping rod and a clamping block; one end of the clamping rod engages with the guide hole of the second rotating disk via a guide rod, and the other end passes through the support ring and is connected to the clamping block via bolts.

[0015] Furthermore, the guide hole of the second rotating disk is a variable diameter trajectory hole, and rotating the second rotating disk can realize the back-and-forth movement of the clamping rod.

[0016] Furthermore, the clamping block engages with the support edge of the cylinder liner, thereby clamping the cylinder liner.

[0032] A variable diameter adaptive assembly piston assembly device, such as Figures 1-3 As shown, it includes a support ring 1, a telescopic assembly 2, a clamping assembly 3, a first rotating disk 4, and a second rotating disk 5;

[0033] Several of the aforementioned telescopic components 2 are installed on the upper part of the support ring 1 via a first rotating disk 4;

[0034] Several of the clamping components 3 are installed to the lower part of the support ring 1 via the second rotating disk 5;

[0035] The telescopic component 2 is used to complete piston assembly; the clamping component 3 is used to clamp cylinder liner 9; the telescopic component 2 and the clamping component 3 are evenly distributed.

[0036] Preferably, the outer circumferential surface of the support ring 1 is provided with two annular grooves 11, and the first rotating disk 4 and the second rotating disk 5 are respectively disposed in the two annular grooves 11.

[0037] Preferably, the telescopic assembly 2 includes a telescopic rod 21, a guide plate 22, a limiting block 23, and a spring 24; one end of the telescopic rod 21 is engaged with the guide hole 6 of the first rotating disk 4 through the guide rod 7; the other end passes through the support ring 1 and is hinged to the middle of the guide plate 22.

[0038] The upper part of the guide plate 22 is connected to the support ring 1 by a spring 24;

[0039] The lower part of the guide plate 22 is connected to the telescopic rod 21 through the limiting block 23. The guide plate 22 and the limiting block 23 are fixedly connected by the pin 25. The limiting block 23 and the guide plate 22 are in contact.

[0040] The limiting plate and the telescopic rod 21 are rigidly connected and move together; the function of the limiting plate is to restrict the guide plate 22 and prevent the guide plate 22 from forming a funnel-shaped guide cylinder that is smaller at the top and larger at the bottom.

[0041] Preferably, the guide hole 6 of the first rotating disk 4 is a variable diameter trajectory hole, and rotating the first rotating disk 4 can realize the forward and backward movement of the telescopic rod 21.

[0042] Preferably, the clamping assembly 3 includes a clamping rod 31 and a clamping block 32; one end of the clamping rod 31 is engaged with the guide hole 6 of the second rotating disk 5 through the guide rod 7, and the other end passes through the support ring 1 and is connected to the clamping block 32 by bolts.

[0043] Preferably, the guide hole 6 of the second rotating disk 5 is a variable diameter trajectory hole, and rotating the second rotating disk 5 can realize the back-and-forth movement of the clamping rod 31.

[0044] Preferably, the clamping block 32 is engaged with the support edge of the cylinder liner 9, thereby achieving clamping of the cylinder liner 9.

[0045] Preferably, the first rotating disk 4 and the second rotating disk 5 are provided with scale lines 8, which can be used for rotation adjustment according to the scale lines 8.

[0046] Working principle

[0047] The device is placed on the top surface of the crankcase cylinder. The second rotating disk 5 is rotated and adjusted to the corresponding outer diameter of the cylinder liner 9 according to the scale line 8. The second rotating disk 5 drives the clamping rod 31 to move through the guide hole 6, so that several clamping blocks 32 can clamp the cylinder liner 9, thereby achieving precise positioning of the device.

[0048] Then, rotate the first rotating disk 4 and adjust the scale line 8 to the corresponding cylinder liner 9 diameter. The second rotating disk 5 drives the telescopic rod 21 to move through the guide hole 6. The telescopic rod 21 drives the guide plate 22 to move, forming an intermittent guide cylinder device at the center of multiple guide plates 22. This realizes the variable diameter setting of the piston assembly device.

[0049] The spring 24 connected to the upper end of the guide plate 22 stretches the guide plate 22 radially outward along the support ring 1. The guide cylinder formed by multiple guide plates 22 forms a tapered cylinder with a diameter that gradually decreases from top to bottom. The piston assembly is pushed into the guide cylinder and moves downward. As the piston assembly moves downward, the tapered angle of the guide cylinder formed by the guide plate 22 gradually decreases. When the piston ring reaches the middle hinge structure of the guide plate 22, the tapered cylinder becomes a cylindrical cylinder. The diameter of this cylindrical cylinder is the same as the inner diameter of the cylinder liner 9, so the piston ring on the piston assembly can be pressed into the groove of the piston. When passing the middle hinge position of the guide plate 22, the limiting block 23 will limit the guide plate 22. Therefore, the lower part of the guide plate 22 will not expand due to the downward movement of the piston assembly, thus ensuring that the piston ring on the piston assembly can always be in a compressed state. Finally, the piston assembly is pushed into the cylinder liner 9 through the guide plate 22, completing the piston assembly assembly.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
