Embodiment Construction

[0042]Opening the opening of the piston ring helps the PVD cylinder to be manually inserted into the ring or removed from the ring, including a bracket 1 and a single-rod double-acting cylinder 29 . The single-rod double-acting cylinder with piston rod 31 is installed and fixed on the bracket and connected in series in the air pressure line, controlled by a two-position five-way pneumatic foot valve. The operator controls the extension and retraction of the piston rod of the single-rod double-acting cylinder through the two-position five-way pneumatic foot valve. The present invention also includes push rods 33 on both sides, transmission plate I7 ​​and transmission plate II23 installed on the linear track of the bracket, piston mouth hook plate I5 and piston mouth hook plate II21, and piston ring support plate 35 installed and fixed on the bracket.

[0043] The transmission plate I7 ​​has a thrust surface of the transmission plate I, and the transmission plate II23 has a thru...

Abstract

The invention relates to a device for expanding openings of piston rings to be beneficial to manually sleeving a PVD barrel in the rings or taking the PVD barrel out of the rings. The device is applied to a piston ring production process to sleeve the PVD barrel with the piston rings in batch or take down the piston rings mounted on the PVD barrel in a sleeving manner in batch. The device comprises a support and a single-rod double-acting air cylinder. The single-rod double-acting air cylinder is provided with a piston rod, is fixedly mounted on the support and connected in an air pressure line in series and is controlled by a two-position five-way pneumatic pedal valve. The device is characterized in that the device further comprises a two-side-face push rod, a transmission plate I, a transmission plate II, a piston opening hook plate I, a piston opening hook plate II and a piston ring supporting plate, wherein the transmission plate I, the transmission plate II, the piston opening hook plate I and the piston opening hook plate II are mounted on a linear rail of the support, and the piston ring supporting plate is fixedly mounted on the support; and the transmission plate I is provided with a push force acting face of the transmission plate I, and the transmission plate II is provided with a push force acting face of the transmission plate II. The device has the beneficial effects that acting force is uniformly applied to slightly expand the piston openings, the minimum expanding amount of the piston openings can be selected, sleeving or demounting of the workpiece piston rings can be completed at a time in batch, and production efficiency is high.

Description

technical field [0001] The invention relates to a device that opens the opening of the piston ring to facilitate the manual insertion or removal of the PVD cylinder into the ring, and is used in the production process of piston rings to put the piston rings on the PVD cylinder in batches or to put the PVD cylinder on the PVD cylinder The piston rings are removed in batches. Background technique [0002] The PVD cylinder is a tooling or part used in the PVD treatment process of the piston ring surface. Before the treatment, the piston rings of the same specification need to be stacked on the same PVD cylinder; after the treatment, the treated piston ring needs to be disassembled from the PVD cylinder. The diameter of the PVD cylinder is slightly larger than the inner circle of the piston ring. Therefore, the opening of the piston ring on the PVD cylinder is slightly larger than the opening of the natural state of the piston ring, and the piston ring can be tightly fitted on...
