Description
Technical field
This utility model is related to hydraulic press technical field, more particularly, to a kind of four-column hydraulic press locking device.
Background technology
At present, various hydraulic presses are only locked in limit superior by the support loop in hydraulic system slide block after quitting work
The method of position, can not meet the needs of actual safety in production.In production process, if there is support loop card valve or valve
Situations such as body is damaged, easily causes slide block under the influence of self gravitation, from the automatic slide downward of upper extreme position.This not only can
Mould is damaged, more likely operator is damaged.
For this reason, it is necessary to study a kind of locking device, slide block is locked in into upper extreme position, improves the safety of machine.
Utility model content
The purpose of this utility model is to provide a kind of locking device for locking four-column hydraulic press slide block upper extreme position.
To achieve these goals, this utility model is adopted the following technical scheme that：
A kind of four-column hydraulic press locking device, particularly, including guide rail and the locking seat that vertically can be moved back and forth；This is led
Rail is provided with the closing piece that can be moved back and forth along itself guidance axis；The locking seat is provided with the limited block being engaged with closing piece；Also
Including the driving means for driving closing piece opposite rail to slide；The motion portion of the driving means is connected with slide block.
Principle of the present utility model is as follows：
When locking seat is moved to upper extreme position, driving means action, its motion portion can promote closing piece opposite rail to slide,
Closing piece is put under in locking seat, and positioned at the lower section of limited block, be engaged with limited block.If locking seat is under upper extreme position
Sliding, limited block is slid to closing piece, and closing piece forms effectively stop, it is to avoid locking seat continues to glide.Above-mentioned driving means can be with
Be cylinder, oil cylinder or other be usually used in realizing the executive component of linear reciprocal movement.
Locking seat can be connected by user with the slide block of four-column hydraulic press, and guide rail and driving means are then arranged on four post liquid
On the upper beam slab of press.When the support of the relative four-column hydraulic press of slide block is vertically moved back and forth, locking seat follows slide block phase immediately
Support is vertically moved back and forth.When slide block is moved to upper extreme position, i.e., when locking seat is moved to upper extreme position, driving means
Action, its motion portion promote closing piece opposite rail to slide, and closing piece is put under in locking seat and is located at the lower section of limited block.If four posts
Because of unexpected downslide, slide block drives locking seat to glide to the slide block of hydraulic press, limited block is slid to closing piece, and due to closing piece
Stop and stop gliding, so that slide block stops gliding.User adjusts locking seat and guide rail, the mutual spacing of closing piece, you can make
Upper extreme position of the slider locking in four-column hydraulic press.
During for avoiding locking seat from not moving to upper extreme position, driving means action slides closing piece opposite rail, causes
Closing piece clashes into locking seat, causes potential safety hazard, can be provided with the proximity switch electrically connected with driving means on the guide rail, and locking seat
On be then provided with the first sensor block being engaged with the proximity switch.After locking seat goes upward to upper extreme position, guide rail is arranged at
On proximity switch sense the first sensor block in locking seat, proximity switch sends signal immediately to driving means, makes
Driving means action, drives closing piece to put under in locking seat.
For limiting the stroke of driving means, it is to avoid cause driving means to be damaged because the stroke of driving means is improper, guide rail
On can be provided with the first travel switch for controlling driving means feed distance and for control that driving means reclaim stroke the
Two travel switches, first travel switch, the second travel switch are electrically connected with driving means, and be then provided with closing piece with this
The second sensor block that one stroke switch, the second travel switch are engaged.During driving means feed, on guide rail
When first stroke inductive switching is to the second sensor block being located on closing piece, the first travel switch sends signal to driving means,
Driving means stopping action being made, now, closing piece puts under in locking seat and is located at the lower section of limited block；In the mistake that driving means are reclaimed
Cheng Zhong, when the second travel switch on guide rail senses the second sensor block on closing piece, the second travel switch is sent out
Go out signal to driving means, make driving means stopping action, now, closing piece completely disengages from locking seat.
This utility model passes in and out locking seat by controlling closing piece, so as to realize the upper extreme position of four-column hydraulic press slide block
Locking and release；This locking device is arranged on the outside of the upper beam slab and slide block of four-column hydraulic press so that maintenance and debugging are all more
Plus it is convenient.
