Technical Field
The invention relates to the technical field of locking mechanisms, in particular to a locking mechanism capable of being turned in place.
Background
In some processes, the product under process needs to be turned over for better processing, and a turning plate needs to be used for turning over in the process of turning over the processed product.
The existing turnover plate in-place locking mechanism is mostly completed by adopting a self-locking function of a driving motor, when the turnover plate stays, the driving motor is easy to damage due to overlarge torque, and the service life of the driving motor is shortened.
Disclosure of Invention
The invention aims to solve the defects that in the prior art, most of the in-place overturning locking mechanisms of the turnover plate are completed by adopting the self-locking function of the driving motor, and when the turnover plate stays, the driving motor is easily damaged due to overlarge torque, and the service life of the driving motor is shortened.
In order to achieve the purpose, the invention adopts the following technical scheme:
the turnover in-place locking mechanism comprises a base, wherein two symmetrical mounting seats are fixedly arranged on the base, vertical plates are fixedly arranged at the tops of the two mounting seats, a turnover shaft is arranged between the two vertical plates, the turnover shaft is fixedly provided with a turnover plate, an operation box is fixedly arranged on the outer side of one vertical plate, a cavity is formed in the operation box, one end of the turnover shaft penetrates through the vertical plates and extends into the cavity,
a driving motor is fixedly arranged on the inner wall of one side of the chamber and drives the turnover shaft to rotate,
be located the control box the trip shaft cover is equipped with two brake pads that are close to each other, the fixed cover of driving motor output shaft is equipped with first gear, the fixed cover in the outside of trip shaft is equipped with the second gear, second gear and first gear mesh mutually, and two brake pads are closely laminated with the both sides of first gear respectively.
An elastic plate is fixedly arranged on the inner wall of the top of the cavity, two parallel vertical plates are arranged between the elastic plate and the inner wall of the cavity on one side opposite to the elastic plate, friction blocks are fixedly arranged at the bottoms of the two vertical plates, the two friction blocks horizontally extend in opposite directions and are respectively fixed with the tops of corresponding brake pads, trapezoidal blocks are fixedly arranged on one sides, close to each other, of the two vertical plates, a channel with an equilateral trapezoid-shaped vertical section is formed between the two trapezoidal blocks, an action block is arranged in the channel, the width of the action block is larger than the width of the top of the channel, a driving assembly is in transmission connection with the action block, and the driving assembly can drive the action block to vertically move;
two springs and two guide assemblies which are vertically distributed are arranged between the two vertical plates and the corresponding elastic plates and the inner wall of the cavity.
The guide component comprises a sleeve rod/sleeve connected with the two vertical plates and a sleeve rod/sleeve connected with the corresponding elastic plate and the inner wall of the chamber, and the sleeve rod can be partially inserted into the sleeve in a drawing mode.
Further, carry out longitudinal movement for the drive effect piece, drive assembly includes the electric putter of fixed mounting on the inner wall of cavity top, the one end fixed mounting of electric putter output shaft has the rack, rotate on the inner wall of top of cavity and install the lead screw, and the fixed cover in the outside of lead screw is equipped with the gear, gear and rack mesh mutually, the outside threaded connection of lead screw has the screw block, the bottom of screw block and the top fixed mounting of effect piece.
The invention has the beneficial effects that:
when the two friction blocks are tightly pressed on the two brake pads, the turnover shaft is in a locked state, and the locked state of the turnover shaft needs to be released, the electric push rod is started, so that the output shaft of the electric push rod extends to the maximum distance, the transverse movement of the rack can be converted into the rotation of the screw rod through the meshing relation of the arranged rack and the gear, because the screw rod is in threaded connection with the thread block, when the screw rod rotates, the rotation of the screw rod can be converted into the longitudinal movement of the thread block, the thread block can drive the action block to move upwards, the action block can act on the two trapezoidal blocks to transversely move towards one side away from each other, the extrusion spring deforms, the two friction blocks are separated from the two brake pads, the drive motor is started again to drive the turnover shaft and the turnover plate to turn over, the electric push rod is started again to reset after the turnover plate turns over in place, and the two friction blocks, compared with the traditional locking mechanism of the turnover plate which is self-locked by the driving motor, the locking mechanism of the turnover plate reduces the torque applied to the driving motor, protects the driving motor and prolongs the service life of the driving motor.
In order to solve the problem that when the thread block drives the action block to reset, the two friction plates cannot be attached to the two brake plates again, the reset work of the friction blocks can be facilitated through the spring arranged on the side, close to each other, of the inner wall of one side of the cavity and the elastic plate, and the operation steps are few;
in order to solve the problem that the stability is not high when the action block acts on the trapezoidal block to move, the action block and the two trapezoidal blocks can be in a sliding mode of a sliding rail and a sliding groove through the sliding connection relation of the action block and the two trapezoidal blocks, the action block and the two trapezoidal blocks can not be separated, and the stability of the action trapezoidal block to move can be improved.
