Abstract
The utility model relates to a main body mechanism for a torsion tester, which comprises an oil pressure cylinder and a piston, wherein the oil pressure cylinder is connected with a pressure displaying meter and the piston is arranged in the oil pressure cylinder. The utility model is characterized in that a screw rod used for pushing the piston is arranged in a thread hole at the middle part of a cover plate of one end of the oil pressure cylinder, and an outer end head of the cover plate extended out by the screw rod is provided with a regular polygon end head convenient for torsion. The utility model is not only beneficial for a user to adopt the mechanism to match with a torque-force socket wrench capable of displaying the torque for use so that the torque of a pneumatic socket wrench can be tested, but also has the advantages of simple structure, convenient operation and long service life.
Description
Technical field
The utility model relates to a kind of torque test device main body mechanism.
Background technology
Traditional torque test device is made of bearing 1, oil pressure cylinder 2, piston 3, screw rod 4, nut 5 and tubular key 6 etc. as shown in Figure 1; During work, because nut is subjected to the restriction of flange 7 can only rotate and can not be moved to the left, and screw rod is subjected to the restriction of register pin 8 and flange 9 can not rotate and can only move, when nut 5 is rotated, forcing screw rod 4 to drive piston 3 moves right, make the pressure oil in the oil pressure cylinder produce the pressure variation, and feed back to connected pressure display table, thereby demonstrate the pressure indicating value.When test, the user applies rotary torque to produce certain pressure indicating value with pneumatic tubular key to this mechanism earlier like this; Then can test out the torque under same pressure indicating value with the Torque sleeve spanner that can show moment of torsion and this mechanism's cooperating again.
The defective that this device exists is: (1) is for fear of influencing the effective propelling pressure of piston under equal sectional area, effective external diameter of screw rod is subjected to the restriction of piston size, can only be processed into the following screw rod of M30, and its active length is longer, thereby very easily fractures; (2) in order to prevent that screw rod from rotating, need slot on screw rod and flange 9 and fix with register pin, not only complex procedures inconvenience is installed, and register pin fractures easily; (3) dismounting difficulty is big, because piston is big and stroke is short, can make the stuck piston oil pressure cylinder slightly partially during installation; (4), make screw rod will withdraw from very difficulty of piston in case screw rod fractures, and the broken thing of its distortion fracture can stop up the gap between piston and the oil pressure cylinder; (5) complex structure is not only made difficulty, cost height, and failure rate height, and test is unstable.
Summary of the invention
The purpose of this utility model is to provide a kind of main body mechanism of torque test device, it not only helps the user and adopts this mechanism and can show that the Torque sleeve spanner of moment of torsion is used, thereby test out the moment of torsion of pneumatic tubular key, and simple in structure, easy to operate, long working life.
The utility model is to constitute like this, it comprises the oil pressure cylinder that is connected with pressure display table and is located at the interior piston of oil pressure cylinder, it is characterized in that: be provided with in the middle part threaded hole of oil pressure cylinder one end casing in order to promote the screw rod of piston, the external end head that screw rod stretches out cover plate is provided with so that the regular polygon termination of reversing.
During work, when the user applies rotary torque with pneumatic tubular key to the screw rod of this mechanism, screw rod is advanced and promote piston reach, make pressure oil in the oil pressure cylinder produce pressure and change, thereby and feed back to connected pressure display table and demonstrate certain pressure indicating value; Then can test out the torque under same pressure indicating value with the Torque sleeve spanner that can show moment of torsion and this mechanism's cooperating again.
Than prior art, the utility model be owing to will make the pulling force of piston motion become thrust, thereby have following remarkable advantage: (1) propelling power evenly, steadily; (2) piston does not have hollow, and not only effectively working area increases, and the anti-leak performance is good; (3) the screw diameter size is not subjected to the restriction of piston effective area, but thereby overstriking design preventing that it from fractureing, and impulse stroke shortens and can prevent effectively that also it from fractureing; (4) screw rod can be packed into from the working position, and it is very convenient to change; (5) not only simple in structure, easy accessibility, and cost is low damages for a short time, thereby has long mission life.
Description of drawings
Fig. 1 is traditional torque test device synoptic diagram.
Fig. 2 is the utility model embodiment organigram (dotted portion is depicted as the tubular key with the sexangle termination cooperating of screw rod among the figure).
Embodiment
With reference to Fig. 2, the utility model comprises the oil pressure cylinder 10 that is connected with pressure display table and is located at the interior piston 11 of oil pressure cylinder, it is characterized in that: be provided with in the middle part threaded hole 13 of oil pressure cylinder one end casing 12 in order to promote the screw rod 14 of piston, the external end head that screw rod stretches out cover plate is provided with so that the regular polygon termination of reversing 15.
Above-mentioned regular polygon external end head is in order to maybe can show the sexangle termination of the Torque sleeve spanner cooperating of moment of torsion with pneumatic tubular key.
For the ease of production and processing and dismounting maintenance, the nut 18 in order to the screw rod cooperating that above-mentioned cover plate 12 has the bearing 17 in thread connection hole 16 by perimembranous and is embedded at the bearing middle part constitutes, described oil pressure cylinder through passing its all mural margin connecting through hole 19 and the bolt 20 in the thread connection hole 16 of bearing link with bearing; Described nut medial extremity has the collar flange 21 that is embedded in the bearing medial surface counterbore, the perimembranous of this collar flange is provided with threaded hole 22, and described bearing is provided with corresponding to the threaded hole position of collar flange and runs through through hole 23 and be placed through bolt connection part 24 in the threaded hole that runs through through hole and nut collar flange successively.
The utility model simple structure, easy to use, have bigger application value.
