A drive device with adoption of double-sided rack-circle-shaped synchronous belt comprises a support, a rack-circle-shaped synchronous belt drive gear, a drive rotating shaft, a drive gear pedestal bearing, a rack-circle-shaped synchronous belt driven gear, a driven circular shaft, a driven gear pedestal bearing, a rack-circle-shaped synchronous belt pinion, a pinion rotating shaft, a pinion pedestal bearing, a double-sided rack-circle-shaped synchronous belt, a single-sided rack-circle-shaped synchronous belt and a thin steel plate. When in use, the drive device is welded with a numerical control cutting machine or an automatic welding machine; the drive rotating shaft of the drive device is driven by a motor to drive the numerical cutting machine or the automatic welding machine to reciprocate for to-and-fro processing. In operation no mechanical vibration is produced and no base is needed for the installation of rack, so that the cost and weight of the entire machine can be reduced.
Description
The utility model relates to a kind of being used for and is converted to reciprocating transmission device with rotatablely moving, and further is meant a kind of double cog arc drive unit of band synchronously that adopts.
Being used for to rotatablely move in the machineries such as existing oxyacetylene plasma cantilevered mode digital control cutting machine, oxyacetylene plasma tubular type (comprising cylindrical tube, irregular barrel) numerical control cutting machine, automatic arc welding is converted to reciprocating drive unit, generally all is to adopt rack and pinion directly to mesh.The problem that this engagement system exists is: 1. because rack and pinion is a rigid engagement, so produce the circular runout along gear, this mechanical vibration can't be eliminated, so that influence the quality of processing of production technology.2. because tooth bar must be installed in a machining accuracy height and the basal plane of roughness higher (promptly not too coarse) on, therefore cause consumable material, the processing cost of pedestal is very high.3. tooth bar pedestal that the place is installed must guarantee that also enough strength and stiffness are arranged, thus make and have influence on the pedestal heaviness complete machine and can't realize microminiaturization, thus limited the using scope of machine product.
Because the above-mentioned defective of prior art, the purpose of this utility model, be for machineries such as existing oxyacetylene plasma cantilevered mode digital control cutting machine, oxyacetylene plasma tubular type numerical control cutting machine and automatic arc welding provide employing double cog arc that a kind of supporting use do not have the machinery vibration drive unit of band synchronously, making simultaneously that it need not to provide the pedestal of installation tooth bar and is placed on the irregular working surface also can carry out operation smoothly.
Solution of the present utility model is as follows.It has a support, fixedly be equiped with the driving wheel block bearing in the perforate on the dual-side of support respectively, an active rotating shaft is located in these two driving wheel block bearings, active rotating shaft in support tightens and is fitted with a sector just as step band driving gear, in support, also have take turns footpath size and the number of teeth all with sector just as the wheel footpath of step band driving gear and the number of teeth equates and its axial and sector just as go on foot be with driving gear the sector that axially parallels just as going on foot With a driven gear, sector is equiped with two follower block bearings just as the axial aperture internal fixation of step With a driven gear, a driven circular shaft that is located in these two follower block bearings, its two ends are fixed in the perforate on the support dual-side, sector just as step band driving gear and sector just as the support that goes on foot between the With a driven gear in, it is all identical with the number of teeth and axially all be with small gear with a plurality of sectors that sector is with the quantity that axially parallels of driving gear to be at least 5 just as the step just as going on foot to be equiped with wheel footpath, all fasteningly in the axial aperture of each sector just as step band small gear be fitted with the steamboat rotating shaft, the two ends of every steamboat rotating shaft are located in the steamboat block bearing of fixing installing in the perforate of support dual-side respectively, in support, also has one around being engaged on sector just as step band driving gear, sector is just as the step With a driven gear and a plurality of sector all is processed with engaging tooth just as two outer faces of step band small gear and double cog arc in the form of a ring is with synchronously, have the strip single cog arc that is meshed with it and be with synchronously below the double cog arc is with synchronously, this single cog arc bottom of band synchronously is fixed on the sheet metal of a strip.
The utility model with said structure is when installing and using, the processing main frame and the support of the present utility model of machineries such as aforementioned numerical control cutting machine and automatic arc welding are solidly fixed, simultaneously active rotating shaft of the present utility model are associated in the motor of processing main frame by coupling, retarder.The scene adds man-hour, and synchronous band of the single cog arc that is fixed together and strip sheet metal are placed on the workpiece to be processed of work-yard.Like this, under the drive of motor, sector rotates towards certain direction (as clockwise direction) just as step band driving gear, drive the double cog arc that is meshed with it and be with synchronously, the synchronous band of double cog arc drives sector again and rotates toward the clockwise direction together just as step band small gear just as step With a driven gear and a plurality of sector; Otherwise the double cog arc is with synchronously if sector just as going on foot the band driving gear towards rotation counterclockwise, then drives, sector rotates according to counter clockwise direction just as going on foot the band small gear together just as step With a driven gear and a plurality of sector.Because a plurality of sectors are the engagement of no gap with the synchronous band of double cog arc just as step band small gear this moment, also just make synchronous band of double cog arc and single face sector mesh for no gap between the band synchronously, but because the synchronous band of single cog arc is fixed on the processed piece motionless, therefore just make the utility model remaining part that is positioned at its top together with the processing main frame that is connected, do reciprocating linear motion along the synchronous band of the single cog arc of below, thereby reach the purpose that main frame is back and forth processed.
The utlity model has following advantage: 1. because all driving gears are not directly to be with synchronously with fixed single cog arc to be meshed, but realize engagement indirectly by double cog arc band and the engagement of band synchronously of single cog arc synchronously, so just eliminated effectively along gear beating radially, make complete machine not have the machinery vibration, thereby guaranteed the quality of mechanical technology processing.Such as the minimizing of beating of the cutting head that can make numerical control cutting machine, guarantee that the roughness of cutting surface improves (being that cutting surface is not too coarse).2. the utility model need not to provide for machining accuracy, roughness, the high pedestal of strength and stiffness requirement for the synchronous band of single cog arc is installed, so reduced raw-material consumption, has reduced cost, has alleviated weight, thereby can realize the microminiaturization of complete machine.Even being placed on the irregular working surface, synchronous band of the single cog arc that 3. is fixed together and strip sheet metal also can successfully process.These characteristics are well suited for the split requirement of aforementioned numerical control cutting machine and automatic arc welding, can satisfy and cut on the irregular non-ferrous metal plate with on cylindrical tube, the irregular barrel, thereby the realization conveniently moving is not limited by the work-yard, has just enlarged the using scope of product yet.
