Description
Technical field
The present invention relates to a kind of adjustment mechanism of the bent axle dead-centre position of the continuous grid production line striking machine of green plate, specifically
It is related in a kind of continuous grid striking machine work and adjusts the mechanism that mould time control koji-making axle quickly, is accurately parked in dead-centre position.
Background technology
In the production process of lead-acid accumulator core part grid, the single, double mode of production for continuing to use gravity casting will
Progressively tend to be superseded, and cleaned by the mode of developing, efficiently, a large amount of technique for saving alloy lead material and equipment production continuous slab
The mode of grid increasingly obtains the accreditation of people.Crankshaft structure is being used as continuous grid striking machine mould main motion mode
In equipment, when needing to be finely adjusted mould in striking machine work, changes cutter, changing product type and maintenance etc. and operate
It is required that bent axle can fast and accurately be parked in dead-centre position, original structure be fixed on bent axle a top dead-centre cam and
One stopping cam, the position that cam is detected by two proximity switches send what signal controlled pneumatic clutch to complete, this
The shortcomings that kind structure is that equipment can only be in the frequency of use that equipment manufacturer adjusts（Speed of production）Production, and work as user
Need to adjust frequency of use（Speed of production）During production, bent axle is parked in dead-centre position and will changed, it is necessary to readjust, because
This is very inconvenient.
The content of the invention
Goal of the invention：The invention aims to overcome deficiency of the prior art, there is provided a kind of continuous grid production
The mechanism that mould time control koji-making axle quickly, is accurately parked in dead-centre position is adjusted in the work of line striking machine.
Technical scheme：In order to solve the above-mentioned technical problem, a kind of continuous grid striking machine bent axle dead point of the present invention
Position adjusting mechanism, it includes being located at the synchronous pulley of bent axle one end, and the synchronous pulley is connected with rotary encoder, the rotation
Turn encoder to be fixed on striking machine fuselage side plate, the rotary encoder is connected by PLC with electromagnetism-gas-driving valve, the electromagnetism
Pneumatic operated valve rear portion is connected with pneumatic clutch, and the electromagnetism-gas-driving valve is anterior to be connected with pneumatic triple piece, the pneumatic triple piece
It is connected with pressure switch, the pressure switch is connected by compressed air piping with pneumatic clutch.
The rotary encoder rotates with crankshaft-synchronous.
The synchronous pulley number of teeth on the rotary encoder is identical with the synchronous pulley number of teeth on the bent axle.
The rotary encoder, which rotates a circle, produces 1024 pulses.
Rotation and the stalling of bent axle are to provide electric signal by magnetic valve to be controlled by pneumatic clutch in the present invention, pneumatically from
When clutch is passed through compressed air, bent axle rotation, when not having compressed air, bent axle shuts down.
Due to technologic needs, when bent axle shuts down, extension mould cope plate will be parked in topmost（It is commonly called as dead
Point）.Because extension mould volume is bigger, weigh more than 500 kilograms, bent axle with cope plate it is reciprocating when, inertia is bigger,
Therefore, in order to ensure to extend mould it is accurate be parked in top dead-centre, it is necessary to detect the specific position that bent axle rotates to：
On this ad-hoc location, after pneumatic clutch is stopped bent axle can remained in operation in the presence of inertia about 0.2 second when
In shut down, and the position that this stops is exactly the top dead-centre for extending mould, thus will to crankshaft operation this is specific
Detected position.
Rotary encoder is fixed on striking machine fuselage side plate, is connected by timing belt with bent axle, mounted in rotary encoder
On synchronous pulley it is identical with the synchronous pulley number of teeth on bent axle, it is ensured that bent axle rotates a circle, and rotary encoder is similarly
Rotate a circle, the crankshaft-position signal detected is passed to PLC by rotary encoder, is automatically switched by PLC control electromagnetism-gas-driving valves
Open compressed air to act into pneumatic clutch, stall bent axle.
Rotary encoder often rotates a circle, produce 1024 pulses, each pulse correspond to bent axle rotate a circle it is relative
Angle.For example shut down at the 100th pulse, extension mould is just parked in top dead-centre when stopping, if in the 101st pulse
Place is shut down, then draws in the net position of mould when stopping just not in top dead-centre, but in top dead-centre to the position of former point, therefore, when
After rotary encoder detects crankshaft-position signal, as long as the umber of pulse of bent axle stopping is simply provided on the touchscreen（0-1024）
Bent axle can be just set to be parked in the position of top dead-centre.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：It is reasonable that overall structure of the present invention is set, and makes
The position of bent axle is detected with rotary encoder, accurate, quick, especially for the speed of service when adjusting frequency, bent axle is all
Top dead-centre can be parked in, meets technological requirement, solving over can only used using the structure of proximity switch detection cam
Frequency is parked in top dead-centre, and after rotary encoder, adjustment is very easy, simple to after starting stopping several times, on the touchscreen
The umber of pulse stopped being set（0-1024）Can.
