Compared with the prior art the utility model has following distinguishing feature and good effect.Base of the present utility model adopts casting large-scale rigidity worktable form, thereby can stably support large-sized heavy test specimen; In conjunction with the auxiliary table that is located on the base, be easy to install special-shaped test specimen.Connect the frame that constitutes by many guiding back shafts with back up pad and base, not only improved rigidity, and increased free space; In conjunction with elevating mechanism, go for the test specimen of bigger width and height.Simultaneously,, can eliminate elastic deformation and stand stretch, measure the error that depth of cup produced thereby eliminate because elevating mechanism adopts the double nut clearance adjustment mechanism.Test can reach high precision, and repeatability and repdocutbility error are less than 1%.Therefore, it is low to the utlity model has overall height, and the space setting range is big, the rigidity height, and good looking appearance, the characteristics of wide adaptability are easy to measure heavy type, bigger, higher test specimen and special-shaped test specimen, thin-walled test specimen.
Four, description of drawings:
Fig. 1 is a main pseudosection of the present utility model
Fig. 2 is a side view of the present utility model
Fig. 3 is a vertical view of the present utility model
Five, embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Fig. 1, Fig. 2, Fig. 3 as can be known, the utility model sclerometer liftable frame comprises frame, elevating mechanism, double nut clearance adjustment mechanism.
This frame comprises base 1, back up pad 12 and three guiding back shafts that are not located along the same line 5,16,17 that base and back up pad are linked together; The upper end of above-mentioned three guiding back shafts is packed on the back up pad by fastening bolt 15, and its lower end is packed in the rear portion of base 1 by support axle head cover 3, frame protective cover 4.Because the front portion of base 1 is the planar shaped worktable, be not suitable for special-shaped test specimen, axle class test specimen and other measurement, therefore to process above-mentioned test specimen, just V-arrangement auxiliary table 2 need be installed on base; This auxiliary table is corresponding with the pressure head on adding off-load and measuring unit 6 automatically.
The utility model adopts three guide pillar frames of the high rigidity high position precision that is made of jointly base, three guiding back shafts, back up pads, replaces traditional fixedly toxoplasm structure.Because base 1 adopts casting large-scale rigidity worktable, thereby has increased the worktable contact area, has improved load-bearing capacity and stability, large-scale heavy test specimen can directly be positioned on the big worktable, can reach 120000mm as the useful area of worktable
2, maximum capacity is 2000kg.Owing to leading screw, screw no longer are installed on the base, make that like this gap that was present in originally between leading screw and screw, the worktable is eliminated, the measuring error of Chan Shenging has not just existed yet therefrom; Simultaneously,, also just there is not the concentricity problem between pressure head and the worktable, eliminated the error problem that the side direction unbalance loading causes because base is no longer installed leading screw, screw; And owing on the base leading screw, screw are installed no longer, make that height space obtains saving, can reach 400mm as the maximum space height between base and the pressure head, improve the ability that this machine holds higher test specimen widely, be easy to measure higher test specimen, big test specimen and heavy test specimen.
This elevating mechanism is made of jointly lifting body 7, leading screw 11, three guiding back shafts 5,16,17 and handwheel devices 13.The leading screw 11 that matches with back up pad 12 is installed in centre position at two adjacent guiding back shafts 16,17, the upper end of this leading screw is provided with the handwheel devices 13 that is packed on the back up pad 12, and this handwheel devices comprises the handwheel that is arranged on leading screw one end, is installed in two bearings, axle sleeve and bearing (ball) covers on the leading screw.This lifting body 7 forms thread connection with leading screw, also forms to be slidingly matched with guiding back shaft 16,17, and by mother nut 10 and secondary nut 8 latched positions.Elevating mechanism is because the self-locking performance of leading screw, makes the position relative fixed of lifting body and three back shafts that lead, and lifting body moves up and down when carrying out height control convenient laborsavingly doing, and can improve system stiffness and repetitive positioning accuracy greatly.
This double nut clearance adjustment mechanism comprises leading screw 11, is arranged on lifting body 7, mother nut 10, secondary nut 8, the fastening bolt 14 on the leading screw and adjusts bolt 9.This mother nut is packed on the relative two sides on lifting body top with secondary nut by at least 3 fastening bolts; Adjust bolt 9 and also be equipped with at least 3 on the secondary nut, this least significant end of adjusting bolt can form with lifting body 7 and closely contact.This double nut, the effect of adjusting bolt are: make cooperating between secondary nut 8, mother nut 10 and the leading screw 11 reach no gap by regulating the overhang of adjusting bolt 9, the measuring error that elimination is produced by stand stretch, thus test power precision and measuring accuracy guaranteed.
Elevating mechanism places on the measuring mechanism, more can reduce influence of measurement error.Certainly, according to actual needs, four guiding back shafts can be set also.
Principle of work of the present utility model is: because the operating position relative fixed, and the adjustment in fall head space is to drive the lifting body be installed on the frame leading screw by handwheel devices to move up and down and realize, thereby when needs are adjusted fall head, can rotate handwheel and drive leading screw 10 rotations, because mother nut 10, secondary nut 8 is fixed on the lifting body 7, and lifting body is by two guiding back shafts 16,17 guiding, rotatablely moving of leading screw 10 can be become moving up and down of lifting body thus, thereby drive be installed on the lifting body add off-load automatically and measuring unit 6 moves up and down, realized the adjustment of fall head.Because base 1 is good with the rigidity of frame that guiding back shaft 5,16,17 and back up pad 12 connect and compose, precision is high, thereby can guarantee the accurately reliable of displacement of pressing head.
