Embodiment Construction
[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0023] Such as Figure 1 to Figure 4 As shown, a piston ring and piston assembly device includes a left plate 1 and a right support 2, a horizontal transmission device 3 is installed between the left plate 1 and the right support 2, and the horizontal transmission device 3 is installed There is a sliding seat 4 on which a piston fixing device 5 is installed.
[0024] The horizontal transmission device 3 includes a guide rod 31 and a lead screw 32 that are horizontally installed between the left plate 1 and the right support 2 through bearings, and the lead screw 32 is connected with a motor 33 fixed on the left plate 1, The sliding seat 4 is threadedly connected with the lead screw 32 ; the sliding seat 4 is slidably connected with the guide rod 31 .
[0025] The piston fixing device ...

The invention relates to an assembling device for a piston ring and a piston. The assembling device comprises a left plate and a right support. A horizontal transmission device is installed between the left plate and the right support. A sliding seat is installed on the horizontal transmission device. A piston fixing device is installed on the sliding seat. Two oblique sliding grooves are symmetrically formed in the upper portion of the right support with the middle portion of the right support serving as the benchmark. A pull block is installed in each sliding groove in a sliding manner. A side hook is arranged at one end of each pull block, and a top hook is arranged on the upper side of the middle portion of the right support. A protruding block is arranged on the right side of each pull block. A kidney-shaped frame is arranged behind the two pull blocks and is connected with a first air cylinder. According to the assembling device for the piston ring and the piston, on the basis that the piston is clamped and fixed and the piston ring is supported and installed, the pull blocks are in sliding fit with the oblique sliding grooves, and therefore the inner diameter of the piston ring can be increased, and a free opening of the piston ring can be enlarged as well. On the basis, under the cooperation of transmission sliding of a screw rod of the piston, the piston and the piston ring can be conveniently assembled, and the assembling stability can be ensured.
Description
technical field [0001] The invention relates to a tool for installing a piston ring, in particular to an assembly device for a piston ring and a piston. Background technique [0002] Piston rings are metal rings used to embed in piston grooves. Piston rings are divided into two types: compression rings and oil rings. The compression ring is used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. The piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the corresponding annular groove of the section. The reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer surface of the ring and the cylinder and one side of the ring and the groove. [0003] Generally speaking, there are two ways to assemble the piston ring into the groove of the piston head. One is to directly expand the free opening of ...
