Automatic compensation volume synchronization flow divider

Abstract

The invention discloses an automatic compensation volume synchronization flow divider and relates to the field of mechanical equipment, in particular to an automatic compensation volume synchronization flow divider. The automatic compensation volume synchronization flow divider comprises a cylinder barrel assembly, a piston rod and piston assembly, a guide sleeve assembly and compensating valves and is characterized in that the cylinder barrel assembly comprises a left cylinder barrel, a right cylinder barrel and a connecting flange of the left cylinder barrel and the right cylinder barrel; the left cylinder barrel and the right cylinder barrel are of the same structure and have the same size; the connecting flange comprises two flange plates; the flange plates are respectively screwed at one ends of the left and right cylinder barrels by screw threads; the cylinder walls of the left cylinder barrel and the right cylinder barrel are respectively added with two radial oil holes. The automatic compensation volume synchronization flow divider can accurately implement volume synchronization, adopts the high-pressure compensating valve, the low-pressure compensating valve and a reasonable opening differential pressure setting value, can implement a whole-process automatic self-adaptive compensation function, not only can avoid accumulation, which is caused by processing errors and internal leakage, of synchronization errors, but also can avoid a pressure cylinder effect and ensures that synchronous cylinders have low no-load resistance and long service lives.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an automatic compensation volume synchronous shunting device. Background technique [0002] The double-cylinder synchronous drive method is widely used in various mechanical equipment. Due to load, internal friction, internal leakage, machining errors and other reasons, the two cylinders are not synchronously operated, resulting in torsional loads on the supported structure or low working efficiency of the driven mechanism. The use of synchronous oil cylinders to realize the synchronization of two cylinders is one of the synchronous driving methods that people often use. [0003] At present, there are two main ways to apply the synchronous oil cylinder. One is to connect an ordinary double-acting oil cylinder in series between the two working oil cylinders to achieve synchronization or directly connect the two working oil cylinders in series to achieve synchronization, but thi...

Problems solved by technology

[0004] A double-rod double-acting cylinder with the same or proportional cylinder diameter and piston rod diameter is added to each oil chamber pipeline of the oil cylinder, and the cylinder barrels of the two additional double-rod double-acting cylinders are fixedly connected together, sharing a piston Rod, this method also has the following disadvantages: (1) If for some reason one of the two working cylinders is stuck during operation or reaches the end of the stroke in advance, the oil pressure in the cylinder will be doubled or formed. The high vacuum degree is precisely because of the existence of this "pressurized cylinder effect", especially under heavy load conditions, which will lead to the occurrence of ultra-high pressure, causing damage and poor safety and reliability, making its use reliability not high , short service life and other issues
