Abstract
The utility model relates to a movable tightening nut mounting device, which comprises a traveling car (10), wherein, a hydraulic lifting mechanism (9) and a support saddle (7) are fixed on the traveling car (10); a guide sleeve (2) is arranged inside the support saddle (7); a mounting pad (3) is arranged at the upper end of the guide sleeve (2); a support sleeve (6) is arranged inside the lower part of the guide sleeve (2); a thrust ball bearing (5) is arranged between the guide sleeve (2) and the support sleeve (6); and the bottom surface of the support sleeve (6) is in contact with the upper end surface of a piston rod (8) of the hydraulic lifting mechanism (9). By using the movable tightening nut mounting device, a tightening nut can be easily fastened onto a tie bolt, and the installation is labor-saving, and the operation is convenient.
Description
Technical field
The utility model relates to the forcing press field, especially a kind of packaged type tightening nut erecting device.
Background technology
The forcing press product belongs to the closed framework structure, and through the stretching screw pretension, stretching screw lower end nut need be fastened to below the base.For the small pressure machine equipment of routine, because its " tightening nut " size is little, in light weight, in above-mentioned assembling process, rely on two workmans' strength at most, just can be installed to nut on the bolt; Yet bigger for " tightening nut " specification on the large pressing machine equipment, its diameter can reach 500mm; Thickness can reach 350mm; Weight is at least 400 kilograms, and the stretching screw bottom is at least 1500mm far from the difference in height on ground, relies on artificial strength can't finish the operation of this installation process at all.Past nut installation method is: before turnbuckle is fixed on the lathe, suspension ring are installed to the stretching screw upper end, be connected with the crane hook with lifting rope, the stretching screw of slinging moves downward it, to its bottom behind the lower height in ground, the operator rotates pre-load nut in the lower end, nut plate to screw rod, is installed effort, operating difficulties.
Summary of the invention
In order to solve the problem that exists in the background technology, the utility model provides a kind of packaged type tightening nut erecting device, and this device is fastened to tightening nut on the stretching screw easily, installs laborsaving, easy to operate.
The technical scheme that the utility model adopted is: this packaged type tightening nut erecting device comprises travelling car, be fixed with hydraulicefficiency elevation structure and bearing on the travelling car, be provided with guide pin bushing in the bearing, the guide pin bushing upper end is provided with erecting bed, guide pin bushing is provided with splicing sleeve in the bottom, be provided with thrust ball bearing between guide pin bushing and the splicing sleeve, touch mutually with the piston rod of hydraulicefficiency elevation structure the splicing sleeve bottom surface.
This novel beneficial effect that has is: this is novel simple to operate, flexible, safe in utilization, convenient, and to the different size stretching screw, nut all is suitable for.Hydraulicefficiency elevation structure can enlarge the range of nut erecting bed, makes screw rod under motionless situation, need not to take overhead traveling crane, allows the nut erecting bed realize nut directly is promoted to actual operational position, and making nut is rotatable nut in uphill process.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-workpiece, 2-guide pin bushing, 3-erecting bed, 4-bearing pin, 5-thrust ball bearing, 6-splicing sleeve, 7-bearing, 8-piston rod, 9-hydraulicefficiency elevation structure, 10-travelling car.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further specified: this packaged type tightening nut erecting device comprises travelling car 10, be fixed with hydraulicefficiency elevation structure 9 and bearing 7 on the travelling car 10, be provided with guide pin bushing 2 in the bearing 7, guide pin bushing 2 upper ends are provided with erecting bed 3, be provided with thrust ball bearing 5 and splicing sleeve 6 in guide pin bushing 2 bottoms, touch mutually with the upper surface of the piston rod 8 of hydraulicefficiency elevation structure 9 splicing sleeve 6 bottom surfaces, piston rod 8 pumps through the oil pressure generation in hydraulicefficiency elevation structure 9, like this,, can in bearing 7, make circumference and rotate and move up and down by the guide pin bushing 2 that thrust ball bearing 5 holds up by splicing sleeve 6.
During use; workpiece 1 is positioned on the erecting bed 3; erecting bed 3 upper surface excircles are fixed with bearing pin 4; be subjected to bearing pin 4 protections around the workpiece 1; suppress with handlance, hydraulicefficiency elevation structure 9 is raised to erecting bed 3 needs height and position, and the through hole on turning of work piece 1 or the guide pin bushing 2(guide pin bushing 2 can insert steel pipe and be rotated the application of force); thereby tightening nut is fastened on the stretching screw effectively, carries out pretension.Solve manpower and lifted difficulty motionless, the motionless nut of rotation; Operate very flexible.
Claims (2)
1. packaged type tightening nut erecting device, comprise travelling car (10), it is characterized in that: be fixed with hydraulicefficiency elevation structure (9) and bearing (7) on the travelling car (10), be provided with guide pin bushing (2) in the bearing (7), guide pin bushing (2) upper end is provided with erecting bed (3), guide pin bushing (2) is provided with splicing sleeve (6) in the bottom, is provided with thrust ball bearing (5) between guide pin bushing (2) and the splicing sleeve (6), and touch mutually with the upper surface of the piston rod (8) of hydraulicefficiency elevation structure (9) splicing sleeve (6) bottom surface.
