Abstract

The invention discloses a locking device, which belongs to the technical field of roll grinding machines. The locking device includes: a pressurized cylinder and a fixed arrangement in the casing, a pressurized piston slidably arranged in the pressurized cylinder; an oil chamber fixedly arranged in the casing; the oil inlet of the first delivery pipeline and the oil chamber The oil outlet of the first delivery pipeline is connected with the pressurized cylinder; the telescopic piston cylinder is slidably arranged in the housing; the oil inlet of the second delivery pipeline is connected with the first delivery pipeline, and the oil outlet of the second delivery pipeline The port is connected with the telescopic piston cylinder; the first end of the telescopic piston is fixedly connected with the telescopic piston cylinder, and the second end of the telescopic piston passes through the housing to connect with the locking block; the disc spring is sleeved on the telescopic piston, and the disc spring is set on the housing Inside the body; the oil inlet of the decompression mechanism communicates with the second delivery pipeline, and the oil outlet of the decompression mechanism communicates with the oil cavity. The locking device of the present invention can reduce labor intensity, avoid damage to components, and facilitate operation.

Description

technical field [0001] The invention relates to the technical field of roll grinders, in particular to a locking device. Background technique [0002] At present, the center frame mechanism of Huachen 8480 grinding machine is locked with four bolts. Due to the variety of grinding rolls, the position of the center frame needs to be changed frequently. Every time the support is moved, it is necessary to use a wrench to loosen the bolts. Fasten the four bolts with a wrench, which increases labor intensity and affects work efficiency. Moreover, due to the lack of elasticity of the bolts, when the center frame mechanism is hit by the rollers, it cannot produce a cushioning effect, which is likely to cause damage to the track and the center frame components. The space around the center frame is narrow, and it is limited by the space when tightening the bolts. It is inconvenient to use a torque wrench with an afterburner rod, which makes it difficult for grinders with little stren...
