Description
Technical field
The utility model relates to a kind of industrial cutting equipment, particularly a kind of be used for cutting in vertical drive apparatus of numerical control plasma cutting machine of metal sheet.
Background technology
In the industrial circle, welding structural element all has utilization widely in all trades and professions.The sheet material cutting is the first step in the welding processing process, is the important procedure that guarantees welding quality, and the utilization rate of material is risen several percentage points, and its economic results in society are considerable.Intelligent accurate cutting technique not only can guarantee the welding quality of product, raises labour productivity, simultaneously also make the manufacturing cost of enterprise product descend significantly, shorten life cycle of the product, especially utilize plasma to carry out the groove cutting, from economic angle, it is more and more important to become.Meticulous plasma cutting machines cutting accuracy of numerical control and surface roughness can reach the lower range of laser cutting, invest little, maintaining, operating cost is low, is the first-selected economic cutting equipment that substitutes laser cutting.In steel construction was produced, this product shared ratio in market sale was ascendant trend year by year.
The meticulous plasma cutting technique of class laser is the pith of cutting processing application, is one of advanced in the world at present cutting technique, also is the trend of cutting industry technology development.In recent years, the class laser technology began to be applied to the cutting of thin plate in the metal.Compare with traditional oxy-acetylene, plasma arc cutting, the class laser cutting has that speed is fast, joint-cutting is narrow, the heat affected area is little, the joint-cutting edge-perpendicular is smooth, economy advantage such as save time again.The sheet material otch roughness Ra≤6.3 μ m that go out with the class laser cutting, otch perpendicularity≤1 °, kerf quality reaches the lower range of laser cut quality, and the slot width is about common isoionic 1/2, the common plasma of cut lengths ratio of precision doubles approximately, and cutting speed is higher than laser, when cutting cut deal especially, be common isoionic 5-7 times considerably beyond common plasma the service life of electrode, nozzle.Class laser cutting device cost of investment and operating cost only are 1/4～1/10 of laser cutting machine, and the scope of its cutting material is very wide, but carbon steel, stainless steel, steel alloy and non-ferrous metal etc.
Vertical transmission device of CUT is to cut first slipping mechanism that walks, and whether whether accurately, steadily straight skidding is related to the metallic plate cutting accurate.Because present vertical transmission all is to drive by the motor that is installed in cutting body both sides, and motor and decelerator are installed on the special holder, holder is rotationally connected by hinge and cutting body again.The normally single spill spin block of above-mentioned hinge is formed, though be provided with elastomeric pad, but unavoidable hinge deformation takes place stressed when big, influence the relative position between motor and the longitudinal rail, and further have influence on vertical transmission steadily reach precision.
The utility model content
The purpose of this utility model is to provide a kind of reliable, as to have less straight skidding deviation vertical transmission device of CUT that uses.
The technical scheme that realizes the utility model purpose is:
The vertical transmission device of a kind of CUT, has the holder that is installed on the body, holder is provided with motor, decelerator and the travelling gear that can cooperate with guide rail, said fixing seat left side is connected by hinge through with body, the right side is connected with the body Elastic Sliding, above-mentioned hinge comprises the left-handed rotating vane of fixedlying connected with body, be fixedly connected on dextrorotation rotating vane and bearing pin on the holder, left-handed rotating vane has the left-handed switch block of 3 or 5 spaced sets, the dextrorotation rotating vane has the dextrorotation switch block of corresponding 4 or 6 spaced sets, an above-mentioned left side, be provided with in the middle of the dextrorotation switch block and be used for interting the through hole of bearing pin.
The right side of said fixing seat has lug, and lug is provided with notch, and the backstay that cooperates with the notch of lug on the body is with spring on the backstay.
Benefit of the present utility model is that the hinge of this transmission device adopts the multijaw pivoting leaf to be connected, cooperation between the left rotation and right rotation leaf is tightr, have axial preferably weight capacity, in transmission process, be difficult for deformation takes place, can guarantee the accurately steady of travelling gear and guide rail relative motion; The holder right side of this transmission device is connected with body elasticity, both the travelling gear that is installed on the holder can be pressed on the guide rail, the assurance slippage is accurate, and elasticity connects and can prevent that again the travelling gear and the guide rail field of conjugate action from killing damage equipment under unexpected situation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the exploded perspective view of hinge among Fig. 1.
The specific embodiment
See Fig. 1 and Fig. 2, the vertical transmission device of the utility model has the holder 1 that is installed on the body 100, holder is used for installing drive motors, decelerator and travelling gear, travelling gear is used for and is fixed on longitudinal rail tooth bar engagement on the bottom surface, work workshop, by drive motors work, holder is followed travelling gear guide rail slippage relatively together.The said fixing seat passes on left hinge 2 and is rotationally connected with body, the right side is connected with body elasticity, when the travelling gear on the holder cooperates relative motion with guide rail, with the also relative together guide rail slippage of body 100 of holder connection, cutting machine is just realized lengthwise movement, finishes the cutting task.
Above-mentioned hinge 2 comprises left-handed rotating vane 21, dextrorotation rotating vane 22 and bearing pin 23, left-handed rotating vane has the left-handed switch block 211 of 3 spaced sets, the dextrorotation rotating vane has the dextrorotation switch block 221 of 4 spaced sets, left and right spill spin block can closely snap together, and above-mentioned left and right spill spin block central authorities all are provided with through hole, and bearing pin passes this through hole left and right pivoting leaf is rotationally connected.Cooperate because hinge has the multijaw spill spin block, can bear bigger axial compressive force, be not easy to take place deformation.
The right side of said fixing seat 1 has lug 11, have notch on the lug, the relevant position is provided with backstay 3 on the body 100, backstay passes the notch of lug, be with spring 4 on the backstay, the backstay top is provided with screw thread, and by nut check, spring is tightly pushed down the lug of holder, guarantee that holder is connected with body elasticity.
During the utility model work, electric motor starting also drives the travelling gear rotation, and travelling gear cooperates with the guide rail tooth bar, and relative motion takes place, and the body that is connected with holder is able to along the guide rail slippage.Because be rotationally connected by hinge 1 between holder and the body, hinge has the multijaw spill spin block, at the relative position that still can guarantee under the load-bearing situation between holder and the body, when the body straight skidding cut, it is better that line mass is walked in cutting like this.
Obviously, the above-mentioned specific embodiment of the present utility model only is for the utility model example clearly is described, and is not to be qualification to the utility model embodiment.For those of ordinary skill in the field, can also be easy to make other pro forma variation or alternative on the basis of the above description, and these changes or alternative also will being included within the definite protection domain of the utility model.
