Abstract
The utility model relates to installation of large-sized vertical type oil hydraulic presses, in particular to an elastic force type rotary tray and a method for installing nuts of a large-sized oil hydraulic press stand column. The elastic force type rotary tray comprises a bottom board, a pressure plate and a tray, a spring supporting device is symmetrically arranged between the pressure plate and the bottom board, a guiding sleeve is fixed in the middle of the bottom of the pressure plate, and a guiding column of the guiding sleeve is fixed on the upper portion of the bottom board. The tray is installed on the pressure plate through a thrust ball bearing, staircase-shaped locating blocks are fixed on the upper portion of the tray at intervals in a circumferential distribution mode, and top screws are installed on the locating blocks. The elastic force type rotary tray is simple in structure and low in manufacturing cost, and the installation of the nuts of the large-sized oil hydraulic press stand column is practical. Regardless of the weight and tightened force of the nuts, requirements on installation and fastening can be met by means of selecting proper types of springs, thrust ball bearings and pressure plates, so that the nuts and threads of the stand column cannot be damaged, construction efficiency can be improved, construction labor is reduced, and costs for labor and machinery are saved.
Description
Technical field:
The utility model relates to the installation of large-scale vertical hydraulic press, specifically is a kind of elastic force type rotary-tray.
Background technology:
At present, the volume and the tonnage of hydraulic press are increasing, for the installation of vertical hydraulic press upright nut and fastening, adopt traditional pallet to install and can't be suitable for.Its problem is; The weight of nut reaches 1.4 tons; The center of the centre of gyration of pallet, the center of nut and column is difficult to be consistent, and the frictional force between nut when rotation and the column can be very big, and then can wound occur grinding in external screw thread first buckle of column when nut center and leghole decentraction; If not noting grinding hinders details and can cause the stubborn more wound of more tightly grinding of nut more and more serious, last so that nut can not screw in and can not screw out.
The utility model content:
The utility model is intended to solve the problems referred to above of installation of large-sized hydraulic press upright nut and fastening existence; And provide a kind of nut that can guarantee in fastening process, can not injure itself and column screw thread, can improve the elastic force type rotary-tray of mechanization of building operation degree and efficiency of construction simultaneously.
The technical scheme that the said problem that solves the utility model adopts is:
A kind of elastic force type rotary-tray comprises base plate, platen, pallet, is symmetrically arranged with spring supporting device between said platen and the base plate, and platen bottom center fixed has fairlead, and base plate top is fixed with the lead of this fairlead; Said pallet is installed on the platen through thrust ball bearing, and there is stepped locating piece on pallet top by the circumference fixed interval, and jackscrew is housed on the locating piece.
Said spring supporting device is separately positioned on the corner location of platen and base plate; It is made up of spring, stud, adjusting nut and positioning sleeve; Run through stud in the middle of this spring; This stud upper and lower end passes from the bolt hole of base plate and platen respectively, and is fixed by adjusting nut, and the positioning sleeve of spring is housed on the stud.
Four angles of said base plate are provided with the bolt of adjustment rotary-tray levelness and height.
The dial gauge of measuring the platen falling head is housed between said platen and the base plate.
Compared with prior art, the beneficial effect of the utility model is: simple in structure, cost of manufacture is low, the nut of installing on the large-sized hydraulic press column is had very strong practicality; Nut weight and had much no matter by tight power; Select suitable spring, thrust ball bearing and platen model just can satisfy and install and fastening needs, can guarantee that nut can not injure itself and column screw thread in fastening process, improved efficiency of construction; Reduce construction intensity, practiced thrift manpower and machinery expenses.
Description of drawings:
Fig. 1 is the utility model example structure sketch map front view.
Fig. 2 is the utility model example structure sketch map vertical view.
Among the figure: pallet 1, locating piece 2, jackscrew 3, adjusting nut 4, platen 5, spring 6, positioning sleeve 7, bolt 8, stud 9, fairlead 10, lead 11, thrust ball bearing 12, base plate 13, dial gauge 14, nut 15.
The specific embodiment:
Below in conjunction with embodiment the utility model is described further.
Referring to Fig. 1, Fig. 2, the base plate 13 of elastic force type rotary-tray is rectangle, and four angles of base plate 13 are provided with the bolt 8 of adjustment rotary-tray levelness and height.Bolt 8 adopts the bolt of M30*200, and during use, the bottom of four bolts 8 is provided with backing plate with parts such as the platen 5 on stable support base plate 13 and top thereof and pallets 1.
Be provided with guider between base plate 13 and the platen 5; This guider is made up of fairlead that is fixed on platen 5 bottom centre 10 and the lead 11 that is fixed on base plate 13 central upper portion; Fairlead 10 adopts the steel pipe of Φ 227*4; Lead 11 adopts the steel pipe of Φ 219*4, is welded on respectively on platen 5 and the base plate 13.This guider can guarantee rotating freely of platen 5, and can not cause the levelness of pallet 1 to change because of four spring 6 unbalance stress.
Pallet 1 is installed on the platen 5 through the thrust spherical bearing 12 that its bottom centre is provided with, and the center of the centre of gyration of pallet 1 and nut 15 and the center of column are consistent, and nut 15 can be screwed on the column smoothly.When installed thrust spherical bearing 12; Needing is respectively circular draw-in grooves of thrust ball bearing 12 processing on platen 5 and pallet 1, and the degree of depth is advisable at 3mm, guarantees that thrust ball bearing 12 centers are consistent with pallet 1 center; Thereby make the pallet rotation steadily, and can reduce the resistance of pallet 1 rotation greatly.
Pallet 1 top all is equipped with jackscrew 3 by four stepped locating pieces 2 of circumference fixed interval on each locating piece 2.Because column will stretch out nut 15 a part of distances when nut 15 rotated to final stage; The ladder height of four locating pieces 2 promptly processes by the distance that column stretches out; Guaranteed that 1 on nut 15 and pallet have enough gaps, can not hinder stretching out of column, nut 15 disposable rotations are put in place.When the pivot of nut 15 and thrust ball bearing 12 is inconsistent, can utilize the position of jackscrew 3 accurate adjustment nuts 15, guarantee that nut 15 is consistent with the pivot of thrust ball bearing 12 and play hold-down nut 15.
The dial gauge 14 of measuring the platen falling head is housed between platen 5 and the base plate 13.Can measure the falling head of platen 5.
