Flat process need to be with the experience of operating personnel, the bad control of precision；（3）Hydraulic system has certain leakage unavoidably, so every one section
Time will influence operating efficiency to machine again leveling；（4）Even machine two platforms in zero load are flat, two during load
Platform there is also height tolerance, and machine normal use is influenceed when deviation is big.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of automatic leveling shearing type lifter, energy
It is cumbersome to solve existing shearing type lifter leveling process, two workbench when will repeat leveling and load at interval of a period of time
The problems such as difference in height is excessive.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：One
Kind automatic leveling shearing type lifter, including oil pressure unit, control system and two lifting machine bodies, each lifting machine body include
Base, workbench and two shear type frames between base and workbench, two shear type frames are parallel to each other and right
Claim, the bottom surface of the workbench of lifting machine body is provided with button magnet, and the base of lifting machine body is provided with regulating bolt, the tune
Section bolt is provided with magnetic sensor, and reflective photoelectric sensor is provided with the inside of the workbench of a lifting machine body, another
Reflecting plate is installed on the inside of the workbench of individual lifting machine body, the control system includes programmable controller and pressure sensor,
The oil pressure unit includes hydraulic pump and two oil cylinders, magnetic sensor, pressure sensor and reflective photoelectric sensor with volume
Range controller is connected, and pressure sensor is also connected with the workbench of lifting machine, and two oil cylinders are connected by magnetic valve and hydraulic pump
Connect, magnetic valve is connected with programmable controller again, and the workbench in lifting machine body rises in the presence of oil cylinder.
Further, the control system also includes transformer and breaker.
Further, the regulating bolt is stainless steel bolt.
The beneficial effects of the utility model are：Two workbench of two lifting machine bodies in the utility model are past to be risen
When, the signal intensity of workbench rising, programming control can be obtained by the cooperation of two button magnet and two magnetic sensors
Device processed is by the signal intensity that receives, by repairing of the solenoid valve control to two oil cylinders, and then realize two workbench from
Same position synchronously rises, and ensures that two workbench are in a working depth all the time.After load being added on two workbench, pressure
Force snesor senses weight, the change of the signal for the pressure sensor that programmable controller passes through reception, again by magnetic valve
Adjust repairing to oil cylinder, two workbench of correction because have heavy load and caused by difference in height, ensure two workbench have it is negative
All the time a working depth is in during load.In addition, when be in an emergency cause two height of table difference excessive when, programming control
Device processed can also allow machine to be stopped at once by the signal intensity of the reflective photoelectric sensor received.The utility model
Eliminate the cumbersome leveling process of repetition, solve the problems, such as two workbench in zero load put down and load when injustice, and
Twice after leveling, sustained height is remained without other operations, two workbench during lifting machine normal use.
Brief description of the drawings
Fig. 1 is the structural representation of two lifting machine bodies in the utility model.
Fig. 2 is the attachment structure schematic diagram of the oil pressure unit in the utility model.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
As depicted in figs. 1 and 2, a kind of automatic leveling shearing type lifter, including oil pressure unit, control system and two liftings
Machine body, each lifting machine body include base 1, workbench 2 and being parallel to each other between base 1 and workbench 2
And symmetrical two shear type frames 3, the bottom surface of the workbench 2 of each lifting machine body are provided with button magnet, each lifting machine
The base 1 of body is provided with regulating bolt 8, and the regulating bolt 8 is provided with magnetic sensor 4, the work of a lifting machine body
Reflective photoelectric sensor 9 is installed on the inside of platform, reflecting plate, the control are installed on the inside of the workbench of another lifting machine body
System processed includes programmable controller and pressure sensor 5, and the oil pressure unit includes hydraulic pump 6 and two oil cylinders 7, magnetic sensor
4th, pressure sensor 5 and reflective photoelectric sensor 9 are connected with programmable controller, work of the pressure sensor 5 also with lifting machine
Make platform 2 to connect, two oil cylinders 7 are connected by magnetic valve with hydraulic pump 6, and magnetic valve is connected with programmable controller again, Mei Geju
