Abstract
The utility model relates to an electric flat-nose plier designed for the machine work, which is used for automatically clamping the work piece and mainly used for planing machines, milling machines and surface grinding machines. The electric flat-nose plier comprises an electric control part, a speed reduction part and a drive part. In the electric flat-nose plier, the clamping force can be adjusted according to the size, weight and the material property of the processed component within the range of 25 kg-550 kg. The utility model has the advantages of simple structure, small size, light weight, easy fabrication and convenient operation.
Description
A kind of electronic flat-nose pliers, it is manually designing on the flat-nose pliers basis.Mainly form, be mainly used in planer, milling machine and surface grinding machine by automatically controlled part, the part of slowing down, driving part.
Factory's extensive use is manual flat-nose pliers at present, has occurred application hydraulic pressure and pneumatic flat-nose pliers afterwards again.Manually flat-nose pliers mainly relies on manually to shake and removes coming holding workpiece, and labour intensity is bigger, inefficiency, and the operator does not note sometimes, removes often to injure workman's pin by a crashing object falling down, and is unfavorable for safety.Hydraulic pressure and pneumatic flat-nose pliers are that applying pressure oil and compressed air promotion moving caliper move holding workpiece.This can't use the producer that some medium or small factory enterprises do not have air compression station and inconvenience to use hydraulic pressure.And use the hydraulic oil container floor space big, and the leakage of oil situation that works together is inevitable, and noise was big when pneumatic flat-nose pliers was worked, and the workman is reluctant to use; These two kinds of flat-nose pliers are when making and install, and required precision is higher, use maintenance difficult.
Newly-designed electronic flat-nose pliers has overcome above deficiency, on manual flat-nose pliers basis, increases automatically controlled part and deceleration and partly designs a kind of practical flat-nose pliers.
Below in conjunction with accompanying drawing concrete structure of the present invention and working condition are described in further detail.
Fig. 1 is the electronic flat-nose pliers of the present invention, the concrete structure profile.
Fig. 2 is that the electronic flat-nose pliers of Fig. 1 is along A-A line cutaway view.
Fig. 3 is the automatically controlled part circuit theory diagrams of the present invention.
With reference to Fig. 1, Fig. 2, electronic flat-nose pliers, it is to be that 6 millimeters screw threads are that trapezoidal bull screw mandrel (3), screw mandrel two ends cooperate with caliper (1) by copper sheathing (4), (5) by moving caliper (2), pitch; Moving caliper (2) is combined integrated with nut (12); Gear (6) combines with the worm screw (7) of bull trapezoidal thread; Gear (6) is connected with the micromachine (10) of reduction box (9) outside with gear (8) engagement back; Worm gear (11) combines with screw mandrel (3).With reference to Fig. 3 when pressing the button 1AN, electric current forms the loop by the normally-closed contact of A.C. contactor 2CJ and the coil of A.C. contactor 1CJ, circuit is connected, motor (10) rotating band moving gear (8) rotates, gear (8) driven gear (6), worm screw (7), worm gear (11) rotate, worm gear (11) drives screw mandrel (3) and rotates, and orders about nut (12) and moves forward, and promotes moving caliper (2) clamping work pieces.
Electric current relay LJ is connected in the circuit, and when workpiece is pressed from both sides when stressed, motor is rotated further that current strength increases gradually in the circuit, and when electric current reached predetermined value, the normally-closed contact of electric current relay LJ disconnected, and the current motor that cuts off 1CJ stops operating.At this moment workpiece is clamped, can carry out machining.After workpiece processes, press the button 2AN, A.C. contactor 2CJ work, the motor counter-rotating, moving caliper (2) moves backward, unclamps clamped workpiece.
When processed workpiece poor rigidity or sheet parts, the little or forging of force request, blank require stressed when big, can adjust electric current relay, change size of current in the circuit, to reach suitable clamping force.25～550 kilograms of the electronic flat-nose pliers of the present invention, clamping force adjustable extents.
The present invention not only realizes the automation of holding workpiece, alleviates operator's labour intensity, increase work efficiency, and designed electric flat-nose pliers volume is little, in light weight, simple in structure, make installation and be very easy to, use safety, easy to maintenance, be the very practical anchor clamps of present medium or small factory.
