Abstract
The utility model discloses a synchronous detecting device for the multi-cylinder linkage in the field of the hydraulic machine, comprising a shell fixed on the cross beam of the hydraulic machine. The shell is provided with a first rotary shaft, the end of which is provided with an inputting gear; the sliding block of the hydraulic machine is fixed with a gear rack engaging with the inputting gear; the shell and the fist shaft space is vertically provided with a second rotary shaft, and the first rotary shaft and the second rotary shaft are connected through a worm and a worm wheel; a third rotary shaft parallel to the second rotary shaft is arranged, and the second rotary shaft and the third rotary shaft are connected through a increasing gear pair; the end of the third gear extending out of the shell is connected with a rotary encoder transmitting the speed signal to the control system. When in use, a plurality of cylinders of the hydraulic machine are set, and the speed signal of the sliding block moving is transmitted to the control system through the rotary encoder, and the control system regulates the oil inlet amount of the cylinders, ensuring the synchronous run of the cylinders of the hydraulic machine and achieving good synchronism of the hydraulic machine and more reliable operation.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly the multi-cylinder of large hydraulic press interlock checkout gear.
Background technology
In the prior art, large hydraulic press generally all adopts many oil cylinder linkage works, and the multi-cylinder interlock must guarantee that each cylinder is synchronous.Present synchronisation measures has machinery and the synchronous two kinds of forms of hydraulic pressure, and what hydraulic press generally adopted is a kind of form in back, and promptly hydraulic pressure is synchronous; Detect the general synchronously grating chi that adopts, the employing magnetic railings ruler is also arranged, but magnetic railings ruler not only cost is high, it is had relatively high expectations to working environment, the abominable working environment such as vibrations, dust, greasy dirt that can not adapt to hydraulic press, the sync detection device that uses at present is the grating chi, the grating chi passes to control system with the position signalling of different oil cylinder slide blocks during work, control system will pass to proportioning valve or proportioning pump through the output signal that computing obtains, and realize the slide block synchronous working by the flow that changes proportioning valve or proportioning pump.But the grating chi low precision of this synchronous detection, dependability is poor.
The utility model content
The purpose of this utility model provides a kind of hydraulic press multi-cylinder interlock sync detection device, makes its accuracy of detection height, can make the hydraulic press synchronism good.
The purpose of this utility model is achieved in that hydraulic press multi-cylinder interlock sync detection device, comprise the casing that is fixed on the top beam of hydraulic machine, be provided with first rotating shaft in the casing, first rotating shaft is stretched out the outer axle head of housing and is provided with the input gear, its glide direction of slider of hydraulic press upper edge is fixed with a tooth bar, described input gear and tooth bar are meshed, be provided with second rotating shaft with the first rotating shaft spatial vertical in the casing, but the worm screw of warp speedup between first rotating shaft and second rotating shaft, worm-drive connects, be provided with the 3rd rotating shaft with second shaft parallel, be in transmission connection through speed increasing gear train between second rotating shaft and the 3rd rotating shaft, the 3rd gear stretches out the outer axle head of casing and is connected with the rotary encoder that transmits tach signal to control system.
The utility model can be provided with a plurality of at each cylinder correspondence position of multicylinder hydraulic machine, the equal access control system of the signal of its rotary encoder, when slide block moves up and down, the motion of drive rack linear, tooth bar promotes the input gear and rotates, first rotating shaft is rotated, through speedup of worm and gear, again through speed increasing gear train secondary speedup, tach signal is directly hoed the fields to rotary encoder, rotary encoder is that data signal is passed to control system with analog signal conversion, this data signal is corresponding one by one with the running speed signal of a slide block, control system compares the data signal of being accepted, obtain the output signal of each cylinder oil-feed, regulate the oil inlet quantity of each cylinder, make that each cylinder of hydraulic press can synchronous operation through proportioning valve or proportioning pump.This control system is consistent with existing control system, therefore, can transform existing hydraulic press, only needs to increase hydraulic press multi-cylinder interlock sync detection device described in the utility model and gets final product.Compared with prior art, because the precision height of rotary encoder own, can send pulse signal and the overall process of slider of hydraulic press work is controlled and be fed back, make that the synchronism of hydraulic press is better, use more reliable.
