Description
Technical field
The utility model relates to a kind of clip dynamometer, especially a kind of clip dynamometer that is applicable to that small-sized clip class ring-shaped work pieces clamping force is measured.
Background technology
Having on the Oil, Water, Gas pipeline of clip and larynx hoop various device in fields such as auto industry, shipping industry and mechanical industry widely and use, is that sebific duct and various flexible pipe connect fastening desirable accessory.Clip can shrink naturally with the sebific duct distortion and reach the chucking effect, and clamping force changes along with the size of gripped object; The size of larynx hoop clamping force is by the locking torque decision of its clamping screw.The clip clamping force has crucial effects to the sealing of sebific duct and flexible pipe, also can be used as the selection of pipeline transportation oil-air pressure size simultaneously, and carries out the foundation of fault analysis and clip quality judging.The big or small available finite element of the clamping force of clip is analyzed, emulation, but because of the difference and the foozle of actual material all can exert an influence to the clamping force of clip reality, thereby make analysis result and actual conditions deviation occur.In order to obtain the actual value of clip clamping force, the manufacturing enterprise of clip need carry out actual measurement to the clip clamping force, but the report of also not measuring both at home and abroad at the clip clamping force.
Utilize hydraulic transmission technology to carry out the existing relevant bibliographical information of force measurement, for example, " hydraulic pressure device for measuring force " that [enterprise technology exploitation] 10 phases of calendar year 2001 deliver provides the thrust-measuring device of a kind of two rings when bolt is pressurized to certain moment of torsion, and [mechanical engineer] 2003 5 phases " a kind of hydraulic pressure device for measuring force " delivered disclose a kind of fluid power measurement mechanism of clamping force of detent band-type brake.Above-mentioned hydraulic pressure device for measuring force structure is big, does not fit into the measurement of clip class part, the measurement of especially small-sized clip class part.
The utility model content
The technical problems to be solved in the utility model provides a kind of clip dynamometer that utilizes hydraulic transmission technology.
The technical solution of the utility model is: a kind of clip dynamometer, comprise measuring seat, and sounding rod, locating part, screw and tensimeter, sounding rod are provided with stopper slot and O-ring seal; Be provided with oil pocket in the measuring seat, the tensimeter of measuring oil pocket pressure is housed on the measuring seat, the measuring seat head has the measured hole that matches with sounding rod in a lateral direction, and measured hole is communicated with oil pocket by eccentric oilhole, by screw oilhole is sealed; Sounding rod inserts measured hole, and the sounding rod head is positioned at the measuring seat outside, and the measuring seat head is equipped with locating part, and locating part stretches into stopper slot.
In order when clip shrinks, to measure to clamping force, measurement size is finely tuned, also comprise the adjusting bolt, described oil pocket and measuring seat afterbody connect, and measuring seat afterbody cavity inboard is processed with screw thread, and by regulating bolt seal.For the ease of processing and test, measuring seat is selected the sleeve of end sealing for use, and blind end is the measuring seat head, and other end inboard processes screw thread.
Exhaust effect in the oil pocket when improving oiling, and accelerate oil injecting speed, described oilhole upper portion side wall is provided with vent port, by screw vent port is sealed.
The utility model adopts eccentric oilhole structure with sounding rod and the distribution straggly of oil pocket structure, and size is little, satisfy little in through clip clamping force Testing requirement, and simple in structure, compact, light.This clip dynamometer is integrated, and is hand-holdable to small-sized clip on-line measurement, easy to use.The utility model can detect the clamping force of clip (larynx hoop) under different operating modes, and accurate data are provided, to guaranteeing the quality of clip, for oil transportation, feed channel faults analysis provide important reference.The existing demand that the clip clamping force is measured of part clip manufacturing enterprise, this clip dynamometer will have enormous and latent market and be worth.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Clip dynamometer as shown in Figure 1 comprises measuring seat 1, sounding rod 2, locating part 4, screw 5, tensimeter 6 and adjusting bolt 3, locating part 4 preferred stop screws.Sounding rod 5 heads are rounded, and the middle part has stopper slot 21, and an O-ring seal 22 respectively is equipped with in stopper slot 21 both sides; Measuring seat 1 inside is provided with oil pocket 11, and the tensimeter 6 of measuring oil pocket 11 pressure is housed on the measuring seat 1, and oil pocket 11 connects with measuring seat 1 afterbody, and measuring seat 1 afterbody cavity inboard is processed with screw thread, and by regulating bolt 3 sealings; Measuring seat 1 head has the measured hole 12 that matches with sounding rod 2 in a lateral direction, and measured hole 12 is communicated with oil pocket 11 by the oilhole 13 of off-axis.Sounding rod 2 stretches in the measured hole 12, and sounding rod 2 heads are positioned at measuring seat 1 outside, on the measuring seat 1 with on stopper slot 21 opposite positions stop screw is housed, and spacing screw inserts stopper slot 21, and sounding rod 2 can slide along measured hole 12; Oilhole 13 upper portion side wall are provided with vent port 14, by 5 pairs of oilholes 13 of screw and vent port 14 sealings.
When assembling first, to vent port 14 overflows, remove bubble side by side, then with screw 5 sealings from oilhole 13 oilings.Adjust by the extension elongation of regulating 3 pairs of sounding rods 2 of bolt, to satisfy the measurement requirement of different clip internal diameters.During measurement, with hoop sleeve at sounding rod 2 places, locking, reading numerical values from the tensimeter.
At the clip of different inner diameters, can prepare the sounding rod of different length specification; Simultaneously, can adapt to different fluting clips by design sounding rod nose shape and clamp force measurement.
