Abstract

An electric impactor adopts a motor as driving power and comprises a gear reducer, a coordinate power converter, a spring, an impact rod, handles and a switch and the like. The electric impactor can convert kinetic energy generated by rotation of the motor into kinetic energy of linear reciprocating motion through the coordinate power converter. The spring mounted in front of the impact rod so as to keep the motor operating when the impact rod stays still in case of encountering too hard objects, thus, the motor or spare parts can be protected from damage, and the electric impactor can operate and impact continuously.

Description

Electronic ram

Technical field

The impact damage that Fa of the present invention and a kind of energy electric power directly drive be disassembled device, belongs to the industrial technology field.

Background technology

Destructive disassemble or clash into action in our life, often see, as removing body of wall, bump glass etc.At present, it generally all is that the pneumatic type bump is disassembled device that the impact damage that people use is disassembled device because the pneumatic type ram has flexibility and continuity, can change distance ground and clash into, and run into object really up to the mark also can be because clashing into a static driving element that damages.The pneumatic actuation ram can be accomplished flexible like this, be because what use is that the gases at high pressure of high pressure tank promote the bump head and clash into, also can only be static even if run into object really up to the mark, this also be equivalent to the temporary close valve, any parts is produced and destroys.But the air accumulator that pneumatic ram uses can cause that gas atmosphere reduces owing to constantly discharge gas, therefore the power pump must be installed in addition, and the power pump comprises engine part, piston machine part, also has the high pressure gas pipeline part.Like this, an air pressure ram wants operate as normal will attach a series of mechanical apparatus, and this bump that is common people can not use is disassembled device.

Summary of the invention

Too much in order to overcome pneumatic type ram parts, shortcoming such as be difficult to carry, I have invented a kind of ram that directly drives with electric power, it only need a people just the energy both hands pick up and clash into construction continuously, and run into object really up to the mark and also can reduce equipment and weight widely not because of static parts or the motor of damaging of trip rod.

The electronic ram of the present invention technical scheme of taking of dealing with problems is: electronic ram adopts motor as driving force, and electronic ram also comprises mechanical reduction gear, coordinate power changing apparatus, spring, trip rod, hand grip, switch etc.A coordinate power changing apparatus is installed on the electronic ram, an iron is arranged on its ordinate direction, a clamp bar slot is arranged on the abscissa direction, iron and draw-in groove are welded into a whole.

Electronic ram uses be motor as driving force, but motor varies, the power of the work of electronic ram also depends on power of electric motor, uses the more big motor of power, the impact strength of ram is just more big.But if use the excessive motor of power, its weight also can be very big, and the people just is difficult to hand-held, therefore, select the motor that is fit to weight as drive part.The size of the electronic ram also merit watt level because of motor is different, and electronic ram of all sizes, that power is different should be arranged.

The motor that electronic ram uses is with the high speed output energy of rotating shaft, but our required bump is not very at a high speed, therefore necessary high speed rotating shaft is slowed down.Deceleration device only just can be finished the deceleration of rotating speed with one group of pinion drive gear wheel.

Electronic ram uses motor to make the power driving force, but motor is to export energy with the rotation of rotating shaft, by behind the deceleration device equally being the mode of rotation, be the reciprocating kinetic energy of straight line and bump needs, this just need be at electronic ram installation coordinate power changing apparatus.The coordinate power changing apparatus, exactly the kinetic energy that rotates is changed over the kinetic energy of straight reciprocating motion, it have a horizontal draw-in groove and a vertical clamping slot cuboid, circle wheel, one stir bar, put in when being with cuboid to make circular motion together in the draw-in groove when stirring bar, owing to stir bar and can in draw-in groove, do side-to-side movement, the horizontal motion about needn't doing of draw-in groove and cuboid, but the ordinate direction of cuboid vertical clamping slot has not had draw-in groove, therefore stirs bar just with cuboid work rectilinear motion up and down reciprocatingly.

The coordinate power changing apparatus of installing on the electronic ram changes into the power of the rotation of rotating shaft the power of the straight reciprocating motion of cuboid, we install a trip rod at the rear portion of cuboid again, and trip rod just can be moved by the bump that cuboid promotes to move back and forth.But if electronic ram runs into object really up to the mark in clashing into the work of disassembling, trip rod will stop because of obstruction so, and motor also will stop like this, and impaired situation of motor has just taken place for this.In order to address this problem, we add one section spring at the starting end of trip rod, and trip rod runs into the hard thing motor that stops and also can not stop at once like this, moves back and forth but continue the pushing spring.

The beneficial effect of electronic ram of the present invention is: electronic ram makes to promote medium without gas, a lot of equipment and weight have been reduced, electronic ram directly uses the Motor Drive trip rod, also can not damage parts because running into object really up to the mark, can clash into to continuity construction working.

The specific embodiment

Below in conjunction with accompanying drawing and an embodiment electronic ram of the present invention is further detailed.

At first see Fig. 1, Fig. 1 is the end perspective view that the pinion (3) of (2) on motor in the electronic ram (1) driving shaft directly drives a gear wheel (4).This figure is that the high rotating speed how let us understanding produces motor (1) slows down in the vertical mode of carrying out tooth interlock rotation of mutual plane with gear wheel (4) by pinion (3).Have one to stir bar (6) and be vertically fixed on the gear wheel on the lower circumference limit of the gear wheel among Fig. 1 (4), when motor (1) started rotation work, this stirred bar (6) just along with gear wheel (4) is made circular motion.This composite set of Fig. 1 not only reduces the rotating speed of motor (1), and the rotational plane of driving shaft (2) has been carried out vertical change, and the purpose of this change is to allow all devices can in turn laterally connect and transmit kinetic energy.

The motor of electronic ram (1) is the mode output kinetic energy that rotates, but we needed in bump time but is the reciprocating kinetic energy of orthoscopic, and this has just produced the form that the rotation formula that how motor (1) is produced changes into straight reciprocating motion.This device of Fig. 2 is called the coordinate power changing apparatus, and it can change into the rotation formula of stirring bar (6) on the gear wheel (5) form of straight reciprocating motion.Ordinate direction among Fig. 2 has an iron (10) can just pack into the straight reciprocating motion of making draw and insert-type in the sleeve (11); The abscissa direction has a clamp bar slot (8) to stick into to stir bar (6), and the length of draw-in groove (8) should be equal to or greater than the diameter of gear wheel (4), and draw-in groove (8) is integrally welded with iron (7).If we pack into draw-in groove (8) and stir bar (6), stir when making circular motion in the plane coordinate system of bar (6) in Fig. 2, on the direction of abscissa, no matter stir bar (6) and move to which position, draw-in groove (8) has enough lateral separations to hold that its is free movable, and draw-in groove (8) needn't transverse movement; But, on the direction of ordinate, but do not have draw-in groove to hold this and stir bar (6) lengthwise movement, so draw-in groove (8) must do ordinate direction motion with stirring bar (6), that is to say, does in the process of circular motion stirring bar (6), draw-in groove (8) is unnecessary does the motion of abscissa direction, has only the straight reciprocating motion of making the ordinate direction.Because draw-in groove (8) and iron (10) are welded into a whole, so iron (10) is done the straight reciprocating motion of draw and insert-type in sleeve (11), this motion is just conforming to the motion requirement of continuous bump.

Fig. 3 is the embodiment of electronic ram.Fig. 3 shows the critical piece of electronic ram and the relation of the link position between them in the mode of medial side face profile.Among Fig. 3, under the support that is connected and fixed iron (9) and iron set meal tube (11), motor (1), pinion (3), gear wheel (4), coordinate power changing apparatus (7), spring (12), trip rod (13) are connected and installed successively.A very thick and stiff spring (12) has been installed in the iron sleeve (11) among the figure between coordinate power changing apparatus (7) and trip rod (13), when making trip rod (13) static if this makes the electronic ram of this run into object really up to the mark when clashing into work, iron (10) on the coordinate power changing apparatus (7) is the same to continue reciprocating motion compression spring (12) acting, and motor (1) can not shut down yet.Grip among Fig. 3 (14), push-button switch (15), conductor wire (17), plug (16) have all installed, and really one one is closed hand, portable electronic ram.Conductor wire among the figure (17) and can stretch very long, plug (16) can insert common AC Power supply socket.
