Detailed description of the invention
Below by accompanying drawing, technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
embodiment 1
A kind of longitudinal joint back chipping that the present embodiment provides, structure as shown in Figure 1-Figure 3, comprise base assembly, be fixed on the columns assemblies for supporting on base assembly, base assembly comprises the base plate, road wheel and the retaining mechanism on road wheel that are arranged on walking track, and retaining mechanism arranges on the base plate above road wheel by screw-threaded coupling bar; Vertical direction in columns assemblies is provided with ball screw, the top of ball screw to be driven with column motor by drive positioning unit and is connected, the side of columns assemblies is provided with the top that cat ladder leads to column, columns assemblies is provided with linear slide rail from top to bottom, linear slide rail is provided with guide plate, guide plate is connected with ball screw by feed screw nut, is driven on the slide rail of guide plate between column move up and down by ball screw; Guide plate is provided with transverse arm slide rail and guide plate motor, the transverse arm slide rail of guide plate is provided with transverse arm, transverse arm direction is vertical with column direction, and transverse arm is provided with the transverse arm tooth bar parallel with transverse arm slide rail, and transverse arm tooth bar is engaged by the driven wheel on guide plate motor and drives; At one end of transverse arm fixed installation back chipping head, the other end is provided with dust catcher, and back chipping head is connected by leading dirt airduct.
The drive positioning unit of the present embodiment comprises bearing block, thrust ball bearing and deep groove ball bearing, bearing block is fixedly mounted on the top of upright post main, upper bearing (metal) groove and lower bearing groove is respectively equipped with at the two ends up and down of bearing block, be provided with thrust ball bearing, catch, zanjon bearing shim and dust cover in upper bearing (metal) groove successively, in lower bearing groove, be provided with thrust ball bearing and packing ring successively; Ball screw top is provided with one end smooth section and thread segment, and smooth section is through bearing block, and thread segment is passed bearing block and tightened by round nut fixing.
The present embodiment central post assembly is connected by screw on base assembly 1, guide plate 10 is then connected with screw with column 2 by column linear slide rail 7 top shoe, and transverse arm 3 is also connected with screw with guide plate 10 by the slide block on transverse arm linear slide rail, back chipping head 4 and 5, dust catcher are individually fixed in transverse arm two ends, and guide plate 10 is connected with ball screw 6 by feed screw nut.Columns assemblies 2 upper end is mounted with the motor 8 for driving ball screw 6, guide plate 10 is provided with guide plate motor 11, and transverse arm 3 is fixed with transverse arm tooth bar 12, and guide plate motor 11 axle head is equipped with gear, engages drive with transverse arm tooth bar 12.
The drive positioning unit of ball screw by dissimilar bearing with the use of the object reaching " suspension ".Ball screw top has thread segment, its lower for part be smooth section to settle bearing, be ball screw tapping working region below smooth part.Smooth part is divided into upper and lower two parts by bearing block 21, and top is made up of with a thrust ball bearing I17 and catch 20 deep groove ball bearing 13, and bottom is then made up of a thrust ball bearing II18 and a packing ring 19.After assembling, top deep groove ball bearing 13 accepts screw mandrel radial load, and thrust ball bearing I17 accepts axial load, and round nut 14 provides the power hanging screw mandrel.Power, by a correspondingly-sized packing ring 15, is transmitted to transmission deep groove ball bearing 13 inner ring being unlikely to affect bearing by round nut 14.There is a catch 20 between deep groove ball bearing 13 and thrust ball bearing 17, make deep groove ball bearing 13 inner ring power even transition on thrust ball bearing I17, screw mandrel evenly can be rotated and be unlikely to damage bearing.Thrust ball bearing I17 is laid in bottom in bearing block 21, isolates, make screw mandrel tapping end uniform stressed in the running, do not cause damage with packing ring 19 and screw mandrel threaded section.
The specific works process of this example is: move on the supporting station of back chipping front by needing the pipe fitting of operation, adjustment position while welding is to peak, rotated by the rotating of motor 8, drive ball screw 6 and ball nut generation relative motion, and then drive guide plate 10 rise and fall, thus realize the lifting of transverse arm 3, carry out the caliber adapting to this pipe fitting with rotary bistrique 4.By fine setting, guarantee position while welding and the transverse arm direction of motion point-blank.Thereafter start head 4 and dust catcher 5, by starting guide plate board motor 11, driving transverse arm tooth bar 12 with it relative motion to occur, and head 4 is moved forwards or backwards, completing back chipping operation.
Like this, by as above designing and operating, can complete original design object, job safety is reliable, easy to maintenance, failure rate is low, reduces production cost, improves the quality of products, guarantee carrying out continuously of production, be convenient to production line and carry out continuous productive process management, improve company's productivity effect.
