The driving device of the compressive detecting machine has the advantages that moving range of the cross beam is large and moving stability of the cross beam is good.

Description

A kind of gearing of resistance to compression machines
Technical field
The utility model relates to a kind of resistance to compression machines, especially refers to a kind of gearing of resistance to compression machines.
Background technology
The resistance to compression machines mainly is applicable to the test of tension pressure energy power of bearing part, the frock part of metal material.The resistance to compression machines is widely used in Aero-Space, vehicle manufacturing, machine-building, industry analysis and departments such as check and industrial and mining enterprises' technical supervision such as building materials household electrical appliances at present.Resistance to compression machines of the prior art generally comprises crossbeam, hydraulic cylinder, column, base plate; Crossbeam is parallel with base plate; Two root posts are vertically between crossbeam and base plate, and whole resistance to compression testing agency is " mouth " font, and hydraulic cylinder is between column; Crossbeam is connected on the piston rod that hydraulic cylinder stretches out, and crossbeam relies on the flexible up and down purpose that rises and descend that reaches of piston rod.Because crossbeam is directly to link to each other with piston rod; This moment, the cylinder sleeve of hydraulic cylinder must be at the column top or the bottom, and the crossbeam moving range is little, in addition; It is stable bad that crossbeam and piston rod ways of connecting can cause that crossbeam moves up and down, and the situation that has obstruction sometimes takes place.And being connected of hydraulic cylinder cylinder sleeve and column fix also relative complex.
Summary of the invention
The gearing of a kind of resistance to compression machines of the utility model, purpose are in order to solve the problem of the little and mobile stability of prior art middle cross beam moving range.
For realizing above purpose, the technical scheme that the utility model is taked is: a kind of gearing of resistance to compression machines comprises crossbeam, column, hydraulic cylinder and base plate; Two root posts vertically are positioned at the base plate both sides; Hydraulic cylinder is positioned at the vertical base plate that points within the column, and crossbeam is parallel with base plate, and said hydraulic cylinder is the double piston-rod hydraulic cylinder; On the cylinder sleeve of two double piston-rod hydraulic cylinders symmetry hold-down support is installed, the crossbeam both sides are connected with the hydraulic cylinder cylinder sleeve through hold-down support.
Be flexible connection between said crossbeam and the hold-down support.
Said crossbeam bottom is equipped with pick-up unit.
Said pick-up unit is a pressure transducer.
The piston rod of said double piston-rod hydraulic cylinder comprises upper piston rod and lower piston rod, and there is round bar at upper piston rod and lower piston club head place, and the diameter of round bar is less than upper piston rod and lower piston rod, and column top and bottom steel plate have the hole corresponding with round bar.
The beneficial effect of the utility model is:
1, adopt the double piston-rod hydraulic cylinder, the crossbeam both sides are connected with cylinder sleeve through hold-down support, and crossbeam moves along with the mobile of cylinder sleeve, and cylinder sleeve plays the effect of guiding, and the mobile stability that makes crossbeam better, the moving range of crossbeam is bigger.
2, because there is round bar at upper piston rod and lower piston club head place; Column top and bottom steel plate have the hole corresponding with round bar; And the diameter of round bar only need pass the hole on the steel plate with round bar less than upper piston rod and lower piston rod during installation, can accomplish the installation of hydraulic cylinder in the column and fixing.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is that the utility model middle cross beam is connected synoptic diagram with the double piston-rod hydraulic cylinder.
Fig. 3 is the utility model vertical view.
Wherein, crossbeam 1, column 2, base plate 3, double piston-rod hydraulic cylinder 4, cylinder sleeve 5, hold-down support 6, pick-up unit 7, upper piston rod 8, lower piston rod 9, round bar 10, steel plate 11, hole 12.
Embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3 the utility model is described further.
A kind of gearing of resistance to compression machines; Comprise that crossbeam 1, column 2, hydraulic cylinder and base plate 3, two root posts 2 vertically are positioned at base plate 3 both sides, hydraulic cylinder is positioned at the vertical base plate 3 that points within the column 2; Crossbeam 1 is parallel with base plate 3; Said hydraulic cylinder be on the cylinder sleeve 5 of 4, two double piston-rod hydraulic cylinders 4 of double piston-rod hydraulic cylinder symmetry hold-down support 6 is installed, crossbeam 1 both sides are connected with cylinder sleeve 5 through hold-down support 6.
Be flexible connection between said crossbeam 1 and the hold-down support 6.
Said crossbeam 1 bottom is equipped with pick-up unit 7.
Said pick-up unit 7 is a pressure transducer.
The piston rod of said double piston-rod hydraulic cylinder comprises upper piston rod 8 and lower piston rod 9; Upper piston rod 8 has round bar 10 with lower piston rod 9 bar head places; The diameter of round bar 10 is less than upper piston rod 8 and lower piston rod 9, and column 2 tops and bottom steel plate 11 have the hole 12 corresponding with round bar 10.
During use, workpiece to be detected is placed between base plate 3 and the crossbeam 14 motions of control double piston-rod hydraulic cylinder; Because upper piston rod 8 has round bar 10 with lower piston rod 9 bar head places, column 2 tops and bottom steel plate 11 have the hole 12 corresponding with round bar 10, and the diameter of round bar 10 is less than upper piston rod 8 and lower piston rod 9; Round bar 10 passes the hole 12 on the steel plate 11; Making piston rod withstand steel plate 11 must not move up and down, thereby cylinder sleeve 5 drives crossbeam 1 motion, and pick-up unit 7 is equipped with in crossbeam 1 below; Pick-up unit 7 can be pressure transducer or displacement transducer, in order to accomplish resistance to compression or the deformation test to workpiece for measurement.Owing to adopted double piston-rod hydraulic cylinder 4, crossbeam 1 both sides are connected with cylinder sleeve 5 through hold-down support 6, and crossbeam 1 moves along with the mobile of cylinder sleeve 5, and cylinder sleeve 5 plays the effect of guiding, and the mobile stability that makes crossbeam 1 better, the moving range of crossbeam 1 is bigger.The utlity model has the characteristics of the big and mobile good stability of crossbeam 1 moving range.
