[CN 201621365019.7] Rack and pinion cylinder self-locking hydraulic press with buffer mechanism Title: Rack and pinion cylinder self-locking hydraulic press with buffer mechanism Application number: CN 201621365019.7 Applicant: China Shipbuilding Industry Zhongnan Equipment Co., Ltd. Application date: 2016-12-13 Patent Type: Utility Model The utility model belongs to a kind of power machinery, especially a hydraulic device. A rack and pinion cylinder self-locking hydraulic press with a buffer mechanism. The technical solution is: it includes: a housing (11), a rack and pinion cylinder, a crank connecting rod mechanism, a limit locking device and a buffer mechanism; The utility model uses a rack and pinion cylinder to replace the original swing hydraulic press, which reduces the difficulty of processing; the seal is changed from the original rectangular seal to a regular ordinary seal, which reduces the cost; during maintenance and replacement, it can be easily and quickly disassembled and replaced on site; using the self-locking function of the crank connecting rod mechanism itself, a limit pin and a locking pin are added, so that the hydraulic press can reliably self-lock under vibration conditions.
