Description

A kind of small-sized range-adjustable pressure testing table
Technical field
The utility model relates to a kind of oil hydraulic cylinder pressure testing table, especially a kind of small-sized range-adjustable pressure testing table.
Technical background
Because the model of piston-type hydraulic cylinder product is various, stroke is obstructed one, and the detection of product performance is cumbersome, and work pressure test especially generally all is please appropriate authority help test, fails to carry out in inside plants, has prolonged the manufacture cycle of product.
Summary of the invention
The utility model provides a kind of small-sized range-adjustable pressure testing table, can effectively test the performance of single-acting piston type oil hydraulic cylinder, and can regulate the test stroke, is applicable to the single-acting piston type oil hydraulic cylinder of all models.
In order to address the above problem, the technical solution of the utility model is as follows: a kind of small-sized range-adjustable pressure testing table, comprise two stand type support and hydraulic workstation, two stands welds together with a plurality of cross bars, hydraulic workstation is placed on the next door of support, it is characterized in that: described two stands column on one side is provided with relative chute, upwards is provided with multistage hydraulic cylinder gudgeon supporting base from the bottom of pillar successively along pillar; Be provided with slide block in chute, the cross bar at pillar middle part is provided with static pulley; Also be provided with static pulley on the cross bar of cantilever tip, the bottom of support another side pillar is placed with the counterweight Support cushion, is equipped with the counterweight counterweight on the counterweight Support cushion, is connected with steel cable on the counterweight Support cushion, and steel cable is walked around two static pulley and is fixed on the slide block; The counterweight supporting base has hydraulic elevating platform.
Improvement to such scheme is: the middle part at the support hypotenuse is provided with shoulder block, and shoulder block is through chute.
To being in improvement of such scheme: be provided with tooth bar on the described shoulder block, tooth bar is engaged with gear, and gear is externally connected with actuation gear, is with chain on the actuation gear.
Beneficial effect:
The utility model in use is stuck in the gudgeon of the oil hydraulic cylinder that needs pressure testing on the gudgeon supporting base, the top cunning of oil hydraulic cylinder is in slide block, connect hydraulic tube, oil hydraulic cylinder is started working, the fore-set of oil hydraulic cylinder withstands slide block and moves upward, steel cable on the slide block drives the counterweight counterweight by two static pulley, the practical work process of oil hydraulic cylinder has been simulated in vertical pressure testing, not only detected the flow process of oil hydraulic cylinder, but also detected the leak case of oil hydraulic cylinder step by step, data are true and reliable, adopt counterweight formula counterweight, can the regulated at will load, reach different experiment demands, the hydraulic elevating platform that has of multistage gudgeon supporting base and counterweight supporting base is in order to regulate formation the oil hydraulic cylinder of different strokes to be carried out hydraulic pressure pressure testing test.
The shoulder block that runs through the pillar middle part is in order to detect the working procedure of oil hydraulic cylinder in pressurization, just simulate lorry and toppling over the pressure that goods is, tooth bar on the shoulder block and meshed gears and the actuation gear that is connected and chain are in order can just to control shoulder block on the ground, to help through pressurization.
The utility model is simple in structure, function is sound, be suitable for the work pressure test of the single-acting sleeve-type hydraulic cylinder product of all models, can effectively test out every running parameter of single-acting sleeve-type hydraulic cylinder, carry out emulation by operating mode to product, the complete state during exhibiting product work, performance that can the more intuitive understanding product.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a left view of the present utility model.
Embodiment
The small-sized range-adjustable pressure testing table of the utility model as shown in Figure 1 and Figure 2 comprises supporting frame 1, static pulley 2 and 3, rope 4, counterweight counterweight 5, counterweight supporting base 6, gear 7, shoulder block 8, chain 9, slide block 10 and gudgeon supporting base 11, hydraulic elevating platform 12.
Be relative chute on two stands 1 pillar, upwards be provided with a plurality of oil hydraulic cylinder gudgeon supporting bases 11 successively, in chute, be provided with slide block 10, on the cross bar at stent strut middle part, be provided with static pulley 2 from the bottom of stent strut; Also be provided with static pulley 3 on the cross bar on support 1 top, the bottom of support 1 another side pillar is provided with counterweight Support cushion 6, is equipped with counterweight counterweight 5 on the counterweight Support cushion 6, and counterweight Support cushion 6 is provided with steel cable 4, and steel cable 4 is walked around two static pulley 2 and 3 and is fixed on the slide block 10; Counterweight Support cushion 6 has hydraulic elevating platform 12.
Middle part at support 1 pillar is provided with shoulder block 8, and shoulder block 8 is through chute.
Shoulder block 8 bottoms are provided with tooth bar, and tooth bar is engaged with gear 7, and gear 7 is externally connected with actuation gear 7, are with chain 9 on the actuation gear 7.
During work, product to be tested upper end is connected on the slide block 10 by cylinder head, the lower end gudgeon is placed directly on the gudgeon supporting base 11, regulate the weight of counterweight counterweight 5, connect in-line, the beginning emulation pressure testing can detect that level is out of order with level, Frequently Asked Questions such as noise is arranged in level and grade seepage, weld seam leakage of oil, the lifting process.During pressurization, by pulling chain 9, gear 7 is rotated, be moved to the left thereby drive shoulder block 8, pass the rectangular opening on the supporting frame 1, giving the oil hydraulic cylinder fuel feeding, by the obstruction of shoulder block 8, finish pressurized operation then, this moment, pressure was 20MPa.When changing different stroke oil hydraulic cylinder product, adjust by selecting gudgeon supporting base 11 upper supports point, and adjust hydraulic elevating platform 12 under the counterweight supporting base.When tested workpiece stroke changes, by hydraulic elevating platform 12, come the position of adjusting slider 10, reach the effect of adjustment stroke.
