Specific embodiment
Further to illustrate that the present invention is the technical means and efficacy realizing predetermined goal of the invention and being taken, below in conjunction with Attached drawing and preferred embodiment, to specific embodiment, structure, feature and its effect according to the present invention, detailed description is as follows.
As shown in Figure 1-3, a kind of plasma cutter, including support frame 2, support frame include upper bracket 22 and lower bracket 21, driving assembly, driven subassembly and passive component are provided on upper bracket.
Driving assembly includes a drive shaft 3 being hinged on upper bracket, is provided in drive shaft and drives driven subassembly synchronous First transmission mechanism of rotation, the second transmission mechanism for driving passive component intermittent rotary.
Passive component includes a driven axle 4 being hinged on upper bracket, is provided with swing rod 5 on driven axle, is arranged on swing rod Have and move the first sliding block 51 along swing rod, first, which slides through an adjusting screw 53, connects a rope 6, is additionally provided on the first sliding block Clamping screw 52, the first sliding block is fixed on swing rod.
Driven subassembly includes a driven pipe 8 being hinged on upper bracket, and driven bottom of the tube is provided with to be connected with driven pipe Transverse tube 81, the second sliding block 82 moved along transverse tube is provided on transverse tube, transverse tube bottom is provided with stitches along axial item, slit width Degree is greater than outside diameter of rope, and the second slider bottom is provided with the counterbore for accommodating plasma cut head 9, and counterbore is connected with item seam, with Make rope along the counterbore of driven pipe, transverse tube and the second sliding block sequentially pass through after be connected to plasma cut overhead.Driving assembly When driving passive component rotation, passive component pulls plasma cut head to rise by rope, and driving assembly and passive component are de- When from contact, plasma cut head declines under gravity and drives passive component to reset by rope.
In the present embodiment, counterbore is to be provided with limit guide groove on squared counter bore or inner sidewall, avoids cutting head along counterbore It deflects when axially moving up and down.Cutting head does not depart from counterbore in top in lifting simultaneously.
In the present embodiment, it is also equipped with clamping screw 83 on the second sliding block, the second sliding block is fixed on cross bar.
In the present embodiment, the first transmission mechanism is tape handler 7,
In the present embodiment, the second transmission mechanism include setting on the driving shaft do not complete gear 31, be arranged at passive group With partial gear meshed gears 41 on part, the partial gear two, will with respect to multiple teeth are provided on lateral wall The partial gear quartering.
In the present embodiment, the drive shaft top is provided with the handle 32 for rotate driving axis.
In the present embodiment, the lower bracket is rotatably mounted on a pedestal 1, and the upper bracket is liftable to be mounted on On lower bracket.
In the present embodiment, the pedestal 1 is pipeline clamping mechanism.The upper and lower deck of arc-shaped slot is had including two.
In the present embodiment, lower bracket is screwed at the top of upper blocking seat by one first bolt 23, and lower bracket top is provided with perpendicular To slot, upper bracket lower part is provided through the bolt and nut component 24 of vertical slot, locks after the height to adjust upper bracket On lower bracket.
When upper bracket and pipeline coaxial line, for cutting the annular of pipeline upper part, holder pivots certain angle, is used instantly In the intersection shape of cutting pipe side wall.
In the present embodiment, graduated scale is provided on cross bar and swing rod, the graduated scale on cross bar is conveniently adjusted cutting head and exists Radius of turn on X/Y plane, the graduated scale on swing rod are conveniently adjusted cutting head in the lifting distance of Z-direction.
For all cut conduit upper, in use, by fixing pipeline in pipeline clamping mechanism, according to wanting outer diameter tube, institute The intersection to be cut adjusts the position of the height of upper bracket, the rotational angle of lower bracket, the first sliding block and the second sliding block simultaneously It is locked.Rotational handle, handle drive drive shaft turns, and driven pipe is rotated synchronously with drive shaft, so that cutting head be driven to do Planar circumferential rotates, and when the partial gear on gear driven shaft on driven axle is stirred, pulls rope by swing rod, thus Cutting head is lifted, when the tooth for not completing gear is detached from gear, cutting head falls under the effect of gravity, and it is passive to be driven by rope Axis resets, so that a complete annular of complete twin conduit is cut.
As shown in figure 4, driven axle and cutting head also turn 1/4 circle, the z-axis fortune of cutting head when drive shaft turns 1/4 circle It is dynamic to be held from (low) end in the most top of intersection to minimum (top), that is, rope will pull this section of height distance.It is sliding by first The cutting to different-diameter hole is realized in the adjusting of block, the second sliding block.
The calculation formula of the raising distance is h=c-b=[a2+(a+b)2]1/2-b;
Wherein, h is the height distance that rope is drawn high;A is the distance of cable end on driven axle to the first sliding block, b the Distance of the cable end to driven pipe, cable end on driven pipeline to the first sliding block after c rotates 90 ° for driven axle on one sliding block Distance.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though So the present invention is disclosed as above with preferred embodiment, and however, it is not intended to limit the invention, anyone skilled in the art, not It is detached within the scope of technical solution of the present invention, when the technology contents using the disclosure above are modified or are modified to equivalent change The equivalent embodiment of change, but without departing from the technical solutions of the present invention, implement according to the technical essence of the invention to above Any brief introduction modification, equivalent variations and modification made by example, all of which are still within the scope of the technical scheme of the invention.
