A kind of Full automatic servo turning device
Technical field
The utility model relates to the batch automatic production field that is applied to industrial part, relates in particular to a kind of turning device of self-servocontrol.
Background technology
At present, some electric turnover mechanisms in existing industrial circle are mainly by foundation framework, upset motor, overturning frame (band sucker), electronic pallet frame, the compositions such as detector switch.
Principle of work is that workpiece is placed on overturning frame, controls sucker and holds, then by after the rotation of upset driven by motor switching mechanism, go to pallet top, control after pallet arrives a position and stop, control and cancel force of suction cup, workpiece falls to pallet, completes the upset of workpiece.
These switching mechanisms, have controlled by PLC substantially, and wherein the detection of position detects and realizes by switch.
The limitation of above technology is:
(1) detector switch control position is limited, and a part has determined a pallet height, and a pallet height has just required a detector switch.So when accessory size is various, the position of detector switch just requires various.For example, 20 part heights, have just required 20 positions, and configure 20 detector switches in finite space, are very painful things.
(2) impact on production efficiency.The river pagination that PLC controls is to arrive also and stop after detection trigger signal at electronic pallet, then switching mechanism action.Wherein, the speed of electronic pallet is difficult to design, will affect the precision of stop position too soon, has influence on too slowly production efficiency.
Utility model content
The utility model has designed a kind of Full automatic servo turning device, and the technical matters of its solution is: (1) existing electric turnover mechanism cannot meet the part demand of differing heights; (2) existing electric turnover mechanism work efficiency is low.
In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
A Full automatic servo turning device, comprises mechanics and electric control system, and mechanics is comprised of foundation framework (4), flip portion and bracket portion, and flip portion and bracket portion are all installed on foundation framework (4); Turning part is divided by electronics sucker (2), overturning frame (3), turnover transmission rig (5) and turn drive motor (6) and is formed, overturning frame (3) is connected with the workpiece (1) of differing heights by electronics sucker (2), overturning frame (3) one end is connected with turnover transmission rig (5) and does movement in a curve, and workpiece (1) is transferred to bracket (10) from overturning frame (3); Bracket portion is comprised of drive motor bracket (7), bracket transmission device (9) and bracket (10), bracket (10) is connected with drive motor bracket (7) by bracket transmission device (9), and bracket (10) is done perpendicular movement under bracket transmission device (9) effect; Described electric control system is comprised of control system (11) and input system (12), the input end of control system (11) is connected with input system (12), and control system (11) mouth is by signal control electronics sucker (2), turn drive motor (6) and drive motor bracket (7).
Further, bracket portion also comprises bracket guiding mechanism (8), and bracket guiding mechanism (8) is positioned between bracket (10) and foundation framework (4).
Further, drive motor bracket (7) adopts servomotor.
Further, turnover transmission rig (5) is gear transmission structure, gear transmission structure comprises driving wheel, flower wheel and belt, turn drive motor (6) output revolving shaft acts on driving wheel, driving wheel provides belt to drive flower wheel rotation, and overturning frame (3) one end is fixedly connected with flower wheel.
This Full automatic servo turning device is compared with existing electric turnover mechanism, has following beneficial effect:
(1) the utility model, by adopting driven by servomotor bracket, can optional position control stop bracket, realizes the requirement of various height parts to upset.
(2) the utility model adopts digital control system, by comparing the deviation of actual position and setting position, determine that servomotor is with optimized speed drive bracket, reduce the time that overturning frame is waited for bracket, thereby improve the work efficiency of a whole set of switching mechanism.
