Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As Fig. 1, shown in Fig. 2, a kind of detection dolly of hydraulic torque wrench, comprise tool car 100 and be arranged at the moment of torsion testing agency 200 on tool car 100, moment of torsion testing agency 200 comprises base 201, static torque sensor 214, fixed head 204, needle bearing 210 and reacting force post 206, base 201 is connected with tool car 100 by flange and base set bolt 202, the shape that base 201 corresponds to static torque sensor 214 is provided with mounting groove, static torque sensor 214 is arranged in this mounting groove, base 201 is provided with connection square hole in the lower end of mounting groove, the output shaft of static torque sensor 214 bottom loads in this connection square hole, the upper surface of base 201 is evenly provided with multiple dowel hole, fixed head 204 is also provided with multiple dowel hole, fixed head 204 is connected in the upper end of base 201 by register pin 203 and corresponding dowel hole, fixed head 204 is provided with installation through hole directly over mounting groove, needle bearing 210 is provided with in this installation through hole, the input shaft on the top of static torque sensor 214 loads in this needle bearing 210, fixed head 204 is provided with reacting force post mounting hole in the side installing through hole, lining 205 is provided with in reacting force post mounting hole, the bottom of reacting force post 206 is connected in lining 205.
Suitable, anticlockwise moment of torsion bears in moment of torsion testing agency 200, and clockwise moment of torsion and counterclockwise moment of torsion are the contrary moments of torsion in a pair equal and opposite in direction, direction, therefore the mutual counteract of forward and reverse moment, all power is born by register pin 203.The upper surface of base 201 is evenly provided with multiple bolt hole, and fixed head 204 is provided with multiple bolt hole, loads bolt of fixing plate 212 in the bolt hole of fixed head 204 and the respective bolt holes of base 201.Bolt of fixing plate 212 plays fixing fixed head 204, does not bear moment of torsion.So also can fix fixed head 204 without bolt of fixing plate 212 when reality uses, being fixedly connected with fixed head 204 is designed by the vibrations in order to prevent when placing hydraulic spanner to be detected.Static sensor is supported by needle bearing 210, and bearing is import high precision bearing, ensure that alignment degree preferably, all side forces is absorbed, improves measuring accuracy.The effect of lining 205 is protection reacting force posts 206, and when bearing moment of torsion for a long time, the first deformed damaged of lining 205, lining 205 is changed more convenient, and compares reacting force post 206 and fixed head 204 cost is lower.When detecting hydraulic spanner, needing first static torque sensor 214 to be connected to detector 300 by signal wire, reading torque value by detector 300.
As shown in Figure 2, fixed head 204 is provided with at least two head screws and installs through hole, and these head screws install through hole just to the upper surface of base 201, and a head screw is installed in through hole and is provided with a head screw 211.When fixed head 204 is connected by register pin 203 with base 201, in order to assurance device one-piece construction is stable and precision, register pin 203 is all precision-fit with fixed head 204 and base 201, dismounting is just more difficult, the effect of propping up head screw 211 is ejected by fixed head 204, after first set bolt 208 being dismantled during dismounting, with a head screw 211, fixed head 204 is ejected.Fixed head 204 is provided with bearing cap mounting groove in the upper end periphery installing through hole, and a bearing cap 209 is arranged at the upper end of this bearing cap mounting groove and needle bearing 210, and bearing cap 209 is connected by set bolt 208 with fixed head 204.Bearing cap 209 can prevent dust and other foreign material from entering needle bearing 210, affects its precision.Fixed head 204 is provided with suspension ring screw, and the upper end of fixed head 204 is provided with lifting bolt 207, and lifting bolt 207 is connected with suspension ring screw.Lifting bolt 207 is convenient to move fixed head 204 when erecting device.Fixed head 204 is also provided with handle 213.
Moment of torsion testing agency 200 firmly need be arranged on and can bear on the tool car 100 of its weight.At the diverse location of fixed head 204, multiple reacting force post 206 is set, reacting force post 206 has been made into cylinder and square column for adopting high strength alloy steel, check that the reacting force post 206 of each position can bear peak torque, the hydraulic torque wrench within the scope of maximum torque can only be detected, and once can only use a reacting force post 206.During operation, hydraulic spanner and reacting force post 206 is kept to press close to as far as possible.Structure of the present invention is applicable to the detection of most of hydraulic spanner, has various switching tooling can for detection hexagonal hydraulic spanner.
As shown in Figure 1, the worktable 108 that tool car 100 comprises vehicle frame 101, is arranged at the castor 102 of vehicle frame 101 lower end and is arranged on vehicle frame 101, worktable 108 is provided with moment of torsion testing agency mounting hole, base 201 and static torque sensor 214 are positioned at the below of worktable 108, the upper surface of fixed head 204 is concordant with the upper surface of worktable 108, the upper end cover of moment of torsion testing agency mounting hole is provided with cover plate 109, the shape that the middle part of cover plate 109 corresponds to fixed head 204 is provided with mounting hole, and fixed head 204 is positioned at this mounting hole.Be connected with backboard 110 on rear side of the upper end of worktable 108, backboard 110 be connected with supporting plate 111, supporting plate 111 is placed detector 300 and computer 400.The side of vehicle frame 101 is provided with handle 107.Vehicle frame 101 is provided with placement cabinet 103 and hydraulic pump cabinet 104 in the below of worktable 108, and vehicle frame 101 is provided with placement cabinet 103 cabinet door and hydraulic pump cabinet 104 cabinet door by hinge 106, and placement cabinet 103 cabinet door and hydraulic pump cabinet 104 cabinet door are provided with door lock 105.Worktable 108 is also provided with power board Bang Zhi district 112.
Hollow or side are driven type hydraulic torque wrench be arranged in the moment of torsion testing agency 200 of tool car 100 by switching tooling, oil pipe is connected with hydraulic torque wrench, confirms that all links have installed and reliably connected, drive hydraulic pump.Apply step by step to adjust moment of torsion according to set check point, the moment of torsion of the hydraulic torque wrench that static torque sensor 214 bears can be presented on detector 300 in real time, directly can transfer to computer 400 and preserve, realize the detection of hydraulic spanner by software.
Finally should be noted that; above content is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; the simple modification that those of ordinary skill in the art carries out technical scheme of the present invention or equivalently to replace, does not all depart from essence and the scope of technical solution of the present invention.
