Couple between the radial straight-bar of spiral and first usually determines position and angle by manual measurement, human weld, Later all pads are automatically performed by system again；
Rotating servo motor rotation, by the combination driving translation component of lead screw and ball nut along the side parallel with auger bar To translation；The spiral for being rolled place is arc-shaped rather than spiral arc, is the diameter welded since spiral has one end It has been fixed to straight-bar, arc-shaped spiral can all become spiral arc during translating component translation and pullling, and It requires to weld at once with the radial straight-bar to intersect to fix this shape.So each bending roller group is usually as much as possible It is close from the radial straight-bar of welding position, it is welded at once after rolling over.
The course of work of the invention is as described below.
1) auger bar is linked togather by revolute pair and auger bar bracket, and makes the output shaft and strand of rotating servo motor Imperial bar is fixedly connected.
2) left and right horizontal direction is put into multiple radial straight-bars in V-bucket, then radial straight-bar tumbles downwards automatically, on blanking Radial straight-bar is booked in channel.
3) push plate cylinder driving push plate translates forward, the radial straight-bar for being located at blanking upper channel and horizontal channel connection position Shift the connection position of horizontal channel and blanking lower channel onto along horizontal channel, then radial straight-bar is fallen under blanking lower channel On the horizontal shelf of channel；Blocking surface bumping post radial direction straight-bar on barrier plate cannot roll forward.
4) centering parallelly opening-and-closing type pneumatic clamper drives two centering plate synchronous same-speeds to translate in opposite directions, two centering face synchronous same-speeds Translate and clamp in opposite directions the both ends of the radial straight-bar on the horizontal shelf of channel, make the plane of symmetry between radial straight-bar both ends with The axial line of turning rod is overlapped.
5) it promotes short cylinder driving pushing ram and the combination of long cylinder is promoted to translate forward, pushing ram pushes forward overturning folder Claw assembly overturns finger in parallel-segment guide groove along the direction forward slip for the axial line for being parallel to overturning cylinder, overturning folder Claw assembly translates forward, and two straight-bar handgrip clamping slots move to the two sides up and down for being located at radial straight-bar.
6) parallelly opening-and-closing type pneumatic clamper passes through two straight-bar handgrip parallel synchronous closures of overturning pneumatic clamper finger actuation, two straight-bars Handgrip clamping slot clamps radial straight-bar.
7) centering parallelly opening-and-closing type pneumatic clamper drives two centering plate synchronous same-speeds to translate opposite to each other, and two centering faces are left simultaneously The both ends of radial straight-bar.The radial straight-bar in the clamping of straight-bar handgrip clamping slot has been accurately positioned at this time.
8) long cylinder driving pushing ram is promoted to translate forward, pushing ram pushes forward overturning clip claw assembly.
Overturning finger first continues forward slip along the direction for the axial line for being parallel to overturning cylinder in parallel-segment guide groove, Radial straight-bar will push the blocking surface of barrier plate, and barrier plate overcomes the gravitational moment effect of barrier plate weight to turn over around barrier plate shaft Turn, blocking surface is that radial straight-bar gets out of the way access, and radial straight-bar can be smoothly through blanking lower channel opening facing forward.Then it hinders Baffle is restored to initial position around barrier plate shaft reverse flip under the gravitational moment effect of barrier plate weight.
Finally overturning finger slides in overturning section guide groove, and one edge of pushing ram overturns the direction of cylinder axial line to Forward It is dynamic on one side around overturning cylinder axial line overturning, to the front end for promoting long cylinder stroke after pushing ram overturn 90 degree, straight-bar handgrip Radial straight-bar in clamping slot clamping is also converted to vertical placement by axial line is horizontal positioned, at this time position locating for radial straight-bar Set first of exactly auger radial straight-bar should position, the radial direction straight-bar along auger bar radial direction arrangement, The lower end of the radial direction straight-bar and the cylindrical outer surface face contact of auger bar or the distance for having very little are exactly suitble between the two In the fillet weld of welding.
9) adjacent edge between Intelligent welding robot welding first radial straight-bar and auger bar.
10) the raw material round steel of spiral is made successively to pass through corresponding driven roller, the rolling to pressure roller and passive guide roller.It is artificial to survey The size positions and angle between the raw material round steel for determining spiral and first radial straight-bar are measured, manually the arc-shaped of spiral Section bending helically, manually welds together the position that spiral and first radial straight-bar intersect.
11) combination of bolts and nuts is unscrewed.The position of bending roller group is adjusted along the direction of the fixed slide opening of bending roller group, The spiral at the place of being rolled is set to be exactly equal to the radius of spiral at a distance from auger bar axial line.Along roller group sideslip hole tune The position of whole bending roller support, makes the tangential direction for the spiral for being rolled place just along the side of the helix angle of spiral To.Then the combination of screwing bolts and nut again.
12) it unscrews to pressure roller fixing screws, adjusts the position to press roll component along to press roll component installation long hole, make to drive Dynamic roller can roll out the satisfactory spiral of radius of curvature to pressure roller and passive guide roller.Then it screws again to pressure roller fixing screws.
The parameters index of steel be not complete unity, step 11) and 12) in adjustment process be frequently not primary Perfect condition can be reached, need repeatedly to be adjusted according to the result of processing, an auger is completed in every manufacture will summarize Experience, the experience of long-term accumulation are applied to during adjustment next time.
13) repeat step 10) to 12), make the raw material round steel of other several spirals all successively by corresponding driven roller, To the rolling of pressure roller and passive guide roller, make the spiral at the place of being rolled the half of spiral is exactly equal at a distance from auger bar axial line Diameter makes the tangential direction for the spiral for being rolled place just along the direction of helix angle.
14) rotating servo motor, translation servo-motors, all bending servo motors start simultaneously, rotating servo motor Drive auger bar rotation a quarter week.The output revolving speed of these motors has certain proportionate relationship.Rotating servo motor driving When auger bar rotates a quarter week: the distance of translation servo-motors driving translation component translation a quarter screw pitch；Bending Servo motor drives driven roller and passive guide roller, driven roller, the line length that a quarter circle spiral is rolled out to pressure roller and passive guide roller. The spiral just rolled out is arc-shaped, is not spiral arc, but latter section of spiral is welded on the radial straight-bar being just soldered On, the position that the last period of spiral is being rolled is translated component and tears translation, and position between the two will be pullled At spiral arc.
15) repeat step 3) to 8), second radial straight-bar be placed to should position, the radial direction straight-bar is along strand The radial direction of imperial bar arranges, the lower end of the radial direction straight-bar and the cylindrical outer surface face contact of auger bar or have very little away from From the radial direction straight-bar is just closely packed together with all spirals, is suitable for welding between adjacent edge.
16) phase between Intelligent welding robot welding radial direction straight-bar and auger bar, between radial straight-bar and each spiral Adjacent side.
It constantly repeats step 15) and spiral is rolled into automatically arc-shaped, automatic welding to 16), then the present invention has just reached The purpose of adjacent edge between radial straight-bar and auger bar or each spiral.
17) output shaft and auger bar for making rotating servo motor release connection, and auger bar is removed from auger bar bracket, taken Under the auger that has welded.
Beneficial effects of the present invention: can be automatically that the raw material round steel rolling of spiral is in the arc-shaped, and tear into helical arc Shape, automatic group pair, the adjacent edge between automatic welding radial direction straight-bar and auger bar or radial straight-bar and spiral reduce the labor of worker Fatigue resistance improves working efficiency, improves the presentation quality of product.
