Abstract
The present invention relates to a digital controlled pressed liquor presser with a guarded device and precise travel testing devices, which is characterized in that (1) a guarded device is installed between a working table and an upper beam of a digital controlled pressed liquor presser; (2) precise travel testing devices are installed between an upper slide block and the working table and between the lower slide block and the working table. The present invention can overcome deficiency existing in publicly known travel testing devices, and has the characteristics that the presser still has the memory of slide block displacement quantity after the presser is stopped; the final slide block downward displacement quantity and the recorded displacement quantity are consistent; the slide block displacement quantity is tested more precisely, and the precision is high, so the zero position needs not to be sought again when the presser works again. A guarded device is added on the presser, which can prevent operators from mistakenly entering the presser working section, and effectively avoids accidents relating to personal safety.
Description
Technical field
The invention belongs to pressing hydraulic machine, particularly relate to a kind of numerical control pressing hydraulic machine with protection and precise stroke checkout gear.
Background technology
Present known pressing hydraulic machine (hereinafter to be referred as press), be by master cylinder and column under installing on the sill, sliding block under being set with on the column and being contained on the master cylinder, on column, also be set with workbench and top shoe, after installing master cylinder on the entablature, be set in column, top shoe even is loaded on master cylinder, by locknut with entablature, workbench and sill fixing and locking in column, the device for detecting distance of travel that mainly is made of gear and tooth bar all is housed between upper and lower slide block and workbench forms.Because the device for detecting distance of travel that in press, is equipped with, the main composition of its structure is a gear ﹠ rack structure, though the ratio of precision of its detection slider displacement is higher, but also have deficiency, one is after press is shut down, the memory of the no slider displacement amount of press itself, cause the last slide block amount of moving down not conform to, so press need small change position again when working again with the record displacement; Its two because structural reason own, it can not satisfy the requirement to the more accurate detection of slider displacement amount.In addition, because protector is not installed on press, so the unavoidable sometimes accident that relates to personal safety.
Summary of the invention
The present invention provides a kind of that satisfy to slider displacement that more accurate detection requires and have the band protection of slider displacement amount and the numerical control pressing hydraulic machine of precise stroke checkout gear at press itself for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The present invention is by master cylinder and column under installing on the sill, sliding block under being set with on the column and being contained on the master cylinder, on column, also be set with workbench and top shoe, after installing master cylinder on the entablature, be set in column, top shoe even is loaded on master cylinder, by locknut with entablature and workbench and sill fixing and locking in column, all be equipped with between upper and lower slide block and the workbench on the basis that the device for detecting distance of travel that mainly is made of gear and tooth bar forms, it is characterized by: 1. between entablature and workbench protector is housed; 2. respectively and the precise stroke checkout gear all is installed between the workbench at upper and lower slide block.
The present invention can also adopt following technical measures to realize:
The concrete structure of described protector is, by screw rod and nut rebound is installed on entablature, leaves certain displacement between rebound and entablature and the nut, and by screw installation protection network, protection network is loaded on workbench by screw on rebound.
Have at least 3 slotted holes with column direction consistent location on the rebound in above-mentioned protector.
The concrete structure of described precise stroke checkout gear is, on top shoe and sliding block, pass through all mounting brackets of screw respectively, on support, installing rack is housed by screw, axle is housed on installing rack, suit adjusting rod and cover on axle, axle is installed in installing rack by nut, by nut hinge-rod is housed on adjusting rod, and the location magnetic patch is installed in the hinge-rod end; Linear displacement transducer is housed on workbench, maintains the h gap value between linear displacement transducer and the location magnetic patch.
The h gap value that maintains between linear displacement transducer in the above-mentioned precise stroke checkout gear and the location magnetic patch is≤5 millimeters.
Have at least 2 slotted holes with slide block fore-and-aft direction consistent location on the support in above-mentioned precise stroke checkout gear, on support, also have at least 2 slotted holes with slide block left and right directions consistent location.
Advantage and good effect that the present invention has are: because the precise stroke checkout gear is housed in press; therefore it can overcome the deficiency that known device for detecting distance of travel exists; have not only after press is shut down; press itself still has the memory of slider displacement amount; make last slide block amount of moving down and the characteristics that conform to of record displacement, but also have more accurate detection of slider displacement amount and the high characteristics of precision, so when press is worked again; do not need small change position again, only transfer once just to put in place.In addition, on press, increase and adorned protector, can prevent that operating personnel are strayed into the press operation interval, effectively avoid relating to sometimes the accident of personal safety.
