specific Embodiment 1

[0036] Embodiment 1 The advantages of the piston ring assembly equipment are: the installation of the first and second piston rings can be completed in one process, the process is simplified, the work efficiency is improved, and the labor intensity of production personnel can be reduced.

[0037] The second specific embodiment of the piston ring assembly equipment of the present invention is shown in Figure 10, which is roughly the same as the first specific embodiment, the difference is that four support mechanisms 301, 302, 303 and 304 are provided, and the axis of the ring cup 12 is The center is symmetrically arranged, and the front ends of the supporting mechanisms 301, 302, 303 and 304 are trapezoidal, as shown in Figure 4C, when they are in the supporting position, the diameter of the largest inner circle that can be formed by surrounding the front ends of the four trapezoids is smaller than the outer diameter of the piston ring, and Larger than the maximum diameter of t...

specific Embodiment 2

[0038] The piston ring assembly equipment of the specific embodiment 2 uses four support mechanisms to make the support more stable.

[0039] The third embodiment of the piston ring assembling equipment of the present invention is roughly the same as the first embodiment, the difference is that an elastic device is provided between the support mechanism 30 and the driving device for driving its movement, as shown in Figure 11 is a support with a spring 300 Bracing mechanism 30, because the required elastic displacement of supporting mechanism 30 is extremely small, so spring 300 can be replaced by other devices with elastic functions such as rubber pads, when supporting mechanism 30 draws in to the center, the diameter of the inner circle formed by its front end is less than The largest diameter of the ring cup 12. During the descent of the ring cup 12, the squeeze supporting mechanism 30 slides slightly to the outside, and the supporting mechanism 30 leans against the ring cup...

Abstract

The invention relates to a piston ring assembly equipment that comprises the working platform with assisted installation ring and the first pushing structure and also the second pushing structure and at least two support structure for supporting the second piston ring. It uses the static piston ring and the down of the piston to put the piston ring on the piston, further using the support structure to stop of the dropping down of the piston for ring installation and further dropping down to install the first piston ring, to realize the assembly of the first and second piston in one assembly process, with improved productivity, and reduced labor cost.

Description

technical field [0001] The invention relates to a piston ring assembling device, in particular to a piston ring assembling device capable of assembling two piston rings of an engine piston at one time. Background technique [0002] The piston ring is an important part of the engine, it includes the first piston ring and the second piston ring, and its assembly quality has a great influence on the performance of the engine. At present, the assembly of piston rings is mostly carried out by hand or simple tools. In the process of manual assembly, the operator directly holds the piston ring and the piston in his hand, and then aligns the ring groove to snap the piston ring on. If it is too large, it will break or produce imperceptible cracks, which will bury hidden dangers for the normal operation of the engine. [0003] In the prior art, mechanical devices are also used to assemble piston rings. One of the piston ring assembly equipment includes: a worktable with a vertical t...
