Summary of the invention
The utility model has solved the various drawbacks of the partial installation of the sensor that prior art exists, provide a kind of reasonable in design, integrated, go up bottom plate adjust parallel easily, Weighing cell module easy for installation.Novel Weighing cell module is difficult for damaging in installation process, and has high conformity, serviceable life than characteristics such as length.
The utility model has also solved the sensor inconvenient maintenance that prior art exists, and problems such as maintenance cost height provide a kind of easy to maintenance, Weighing cell module that maintenance cost is low.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise upper mounted plate and bottom plate and be located at upper mounted plate and bottom plate between sensor unit, described upper mounted plate is provided with at least 4 through holes, be provided with cramp bar and the anchorage bar vertical with bottom plate with upper mounted plate between described bottom plate and the upper mounted plate, described cramp bar and anchorage bar two ends and described threaded hole match.Before Weighing cell module is installed on the weighing platform, by clamp nut with tightly upper mounted plate and bottom plate are adjusted to parastate (adjusted when dispatching from the factory because of bar, as causing a deviation owing to vibrating in the transportation, and when being necessary to adjust), by mounting hole Weighing cell module is installed on the weighing platform then, one by one each Weighing cell module is installed, after putting down weighing platform the bottom plate of each Weighing cell module is fixed, the anchorage bar that screws out each sensor again breaks away from its lower end and cramp bar, and is at the two ends of anchorage bar installing nut that the upper mounted plate and the weighing platform of Weighing cell module is further affixed respectively then.Like this, the problem of being parallel to each other of upper and lower fixing plate can solve before Weighing cell module is mounted to weighing platform, is beneficial to the leveling of Weighing cell module and center of effort's line of definite sensor, is convenient to the installation of Weighing cell module; When the weighing platform installation, the module of LOAD CELLS has been broken down into trisome, be respectively upper mounted plate (affixed seaming chuck), sensor unit and bottom plate (affixed push-down head), the quality of weighing platform and finished detection by sensor unit by weighing, the effect of cramp bar disappears simultaneously.The physical dimension of last bottom plate and installation dimension and position, hole are by existing weighing platform installation requirement design, and the overall height of Weighing cell module adapts to former weighing platform requirement simultaneously, and the user need not change weighing platform structure and installation dimension.The top of anchorage bar is higher than the about 10mm of upper mounted plate, is beneficial to determine when LOAD CELLS and weighing platform installation mounting hole site.
As preferably, be installed with a pair of symmetry and the cramp bar vertical on the described bottom plate with bottom plate, described cramp bar upper end is provided with internal thread, and described anchorage bar is by matching with the internal thread of cramp bar and being connected with bottom plate.Cramp bar and anchorage bar adopt the split design, can strengthen the intensity of supporting system, have shortened the length of anchorage bar simultaneously, and the stroke when having shortened the anchorage bar operation has improved the convenience of operation.
As preferably, described anchorage bar stage casing is provided with smooth section, and the diameter of described smooth section is smaller or equal to the path of anchorage bar thread segment; The length of described smooth section is more than or equal to the thickness of upper mounted plate.Wherein, set up smooth section in the anchorage bar and can shorten the stroke that anchorage bar turns when operation, make more hommization of operation of the present utility model.
As preferably, be provided with interior hexagonal on the described stud bolt and turn the hole.Can turn the compounding practice in hole when wherein, turning stud bolt by specific purpose tool and interior hexagonal.
Be embedded with nut in the counterbore on the described upper mounted plate, described nut is fixed by the holding screw of its side, in order to avoid when screwing out anchorage bar, cause nut to rotate, prevent from simultaneously to become flexible owing to vibration causes Weighing cell module in transportation, the upper end of described anchorage bar and the internal thread of described nut match.
As preferably, the output cable of described sensor unit is provided with the terminal box assembly.Wherein, the terminal box assembly can be avoided the impaired often phenomenon of cable (being out of shape because of tying up) threading in installation process of traditional sensors, different or the variation of weighing platform structure be can adapt to and individual sensor line length or the short situation of line caused, all cable length has been avoided waste by user oneself decision.
As preferably; be provided with the O RunddichtringO in the seaming chuck of described Weighing cell module, be provided with diaphragm in the push-down head of described Weighing cell module, what guaranteed sensor unit is subjected to the line of force at same straight line; have dust reduction capability simultaneously, protected the surface of contact of stress point.
Therefore, the utlity model has reasonable in design, last bottom plate adjust parallel easily, easy for installation, characteristics such as Weighing cell module is difficult for damaging in installation process, and serviceable life is longer, and is easy to maintenance, and maintenance cost is low.Wherein, adopt the terminal box mode,, need only change it and needn't change other parts, also needn't install cable again, increased the convenience of maintenance, reduced maintenance cost if sensor unit breaks down.Wherein, the cooperation of cramp bar and anchorage bar becomes one module, and has reversibility and operability easily, and anchorage bar has the effect of stud bolt again simultaneously.Wherein, set up smooth section in the anchorage bar and can shorten the stroke that anchorage bar turns when operation, make more hommization of operation of the present utility model.Wherein, set up the intensity that cramp bar can strengthen supporting system, shortened the length of anchorage bar simultaneously, the stroke when having shortened the anchorage bar operation has improved the convenience of operation.Wherein, the top of anchorage bar is higher than the about 10mm of upper mounted plate, is beneficial to determine when LOAD CELLS and weighing platform installation mounting hole site.Wherein, the lower end of sensor unit is connected by radial screw with push-down head, causes output line to be broken to prevent sensor unit from taking place radially to rotate.When Weighing cell module is installed on weighing platform, by mounting hole Weighing cell module is installed on the weighing platform, one by one each Weighing cell module is installed, putting down weighing platform fixes the bottom plate of each Weighing cell module again, the anchorage bar of each sensor of turn breaks away from its lower end and cramp bar again, and is at the two ends of anchorage bar installing nut that the upper mounted plate and the weighing platform of Weighing cell module is further affixed respectively then.Like this, the problem of being parallel to each other of upper and lower fixing plate can solve before Weighing cell module is mounted to weighing platform, is beneficial to not to be subjected on the performance minimum level of Weighing cell module to install to influence, and is convenient to the installation of Weighing cell module; The gravity of weighing platform is born jointly by sensor unit and anchorage bar when weighing platform falls, and has decomposed the power that acts on the sensor unit, and sensor unit is difficult for having protected Weighing cell module because of impacting or damaged by force unbalance.
