Abstract
The utility model relates to an adjusting device of an adjustable roller carrier. The adjusting device comprises a first lead screw and a second lead screw, the first lead screw and the second lead screw are fixedly connected axially via a connecting sleeve, directions of threads of the first lead screw and the second lead screw are opposite, a first nut matching with the first lead screw is assembled on the first lead screw, the outer end of the first lead screw is supported on a first bearing block, a second nut matching with the second lead screw is assembled on the second lead screw, the outer end of the second lead screw is supported on a second bearing block, and a hand wheel is mounted at the outer end of the second lead screw. Two lead screws with opposite thread directions are utilized to drive the corresponding nuts to move and further to drive two rollers to move, so that the adjusting device is simple and reliable in structure and convenient in mounting and maintenance. In addition, the two rollers can be driven to move to the middle or two sides simultaneously and adjusted accurately by aid of the adjusting device, and the lead screws supported on the bearing blocks are flexible in rotation and can bear tension and thrust simultaneously.
Description
Technical field
The utility model relates to the adjustable turning rolls of welding cylindrical shell class workpiece, relates in particular to a kind of adjusting device of adjustable turning rolls.
Background technology
Turning rolls can be regulated the distance between the roller according to the size of barrel diameter for the assisted class equipment of welding cylindrical shell class workpiece, adjustable turning rolls, and with crosshead, the supporting use of electric welding machine can realize the welding of the inside and outside vertical circumferential weld of cylindrical shell class workpiece.Along with expanding economy, the automaticity of production equipment is more and more higher, and turning rolls is widely used in the middle of the mechanical industry.The use of turning rolls makes the quality of weld seam and outward appearance also obtain improving greatly.
Existing adjustable turning rolls is by the distance between the artificial adjustment roller, wastes time and energy.
Summary of the invention
The utility model provides a kind of adjusting device of adjustable turning rolls at the problems referred to above, and this device is adjusted distance between the roller by machine driving, and is convenient and strength-saving.
According to the technical solution of the utility model: a kind of adjusting device of adjustable turning rolls, comprise first screw mandrel and second screw mandrel that link together by the adapter sleeve axial restraint, first screw mandrel is opposite with the thread rotary orientation of second screw mandrel; Be set with first screw that matches on first screw mandrel, the outer end of first screw mandrel is bearing on the clutch shaft bearing seat; Be set with second screw that matches on second screw mandrel, the outer end of second screw mandrel is bearing on second bearing block, and the outer end of second screw mandrel is equipped with handwheel.
Described adapter sleeve is bearing on the 3rd bearing block.
Described the 3rd bearing block is provided with lubricating cup.
Technique effect of the present utility model is: the utility model adopts two opposite rhizoid bars of thread rotary orientation to drive corresponding screw and moves, and and then drive two rollers and move, simple and reliable for structure, installation and maintenance are convenient; The utility model can make two rollers move to centre or both sides simultaneously, adjusts accurately; Screw mandrel is bearing on the bearing block, rotates flexibly, can bear pulling force and thrust simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
As shown in Figure 1 and Figure 2, the utility model is a kind of adjusting device of adjustable turning rolls, comprises that first screw mandrel 2 and second screw mandrel, 7, the first screw mandrels 2 that link together by adapter sleeve 4 axial restraints are opposite with the thread rotary orientation of second screw mandrel 7.The outer end that is set with first screw, 3, the first screw mandrels 2 that match on first screw mandrel 2 is bearing on the clutch shaft bearing seat 1.The outer end that is set with second screw, 6, the second screw mandrels 7 that match on second screw mandrel 7 is bearing on second bearing block 8, and the outer end of second screw mandrel 7 is equipped with handwheel 9.
For first screw mandrel 2 after preventing to connect and second screw mandrel 7 produce the downwarp phenomenons, adapter sleeve 4 can be bearing on the 3rd bearing block 5.
For adapter sleeve 4 is rotated in the 3rd bearing block 5 flexibly, the 3rd bearing block 5 is provided with lubricating cup 11.
Clutch shaft bearing seat 1, second bearing block 8 and the 3rd bearing block 5 in the utility model all are fixed on the support 12 of turning rolls; First screw 3 in the utility model links to each other with the base plate of first roll wheel assembly 13, and second screw 6 links to each other with the base plate of second roll wheel assembly 10.
Operation principle of the present utility model is: when needs regulate between adjustable turning rolls two rollers apart from the time, shake handwheel 9, drive first screw mandrel 2 and 7 rotations of second screw mandrel, because first screw mandrel 2 is opposite with second screw mandrel, 7 thread rotary orientations, first screw mandrel 2 and second screw mandrel 7 order about first screw 3 respectively and second screw 6 moves to adjustable turning rolls centre or both sides, drive first roll wheel assembly 13 and second roll wheel assembly 10 moves to centre or both sides simultaneously, realize adjusting the distance between two rollers.
The utility model adopts two opposite rhizoid bars of thread rotary orientation to drive corresponding screw and moves, and and then drive two rollers and move, simple and reliable for structure, installation and maintenance are convenient; The utility model can make two rollers move to centre or both sides simultaneously, adjusts accurately; Screw mandrel is bearing on the bearing block, rotates flexibly, can bear pulling force and thrust simultaneously.
