The arrival of new technology revolution, the world starts to enter the information age.In the process utilizing information, what first will solve will obtain information accurately and reliably exactly, and sensor is the main path and the means that obtain information in nature and production field, in modern industry produces especially automated production process, the parameters in monitoring and controlling production run is carried out by various LOAD CELLS, make equipment be operated in normal condition or optimum condition, and make product reach best quality.Therefore, the precision requirement that sensor detects is very high.Therefore market has a kind of test machine, utilize load cell, the counterweight of examination criteria weight, thus the degree of accuracy of test load cell, and according to concrete experimental data, carry out offside weight sensor and measure correction, thus ensure the degree of accuracy of sensor.
The counterweight test machine of current detecting sensor, tested sensor is tested after can only being fixed on test platform with hex bolts again.So not only waste time and energy, but also deviate can be produced to test result, thus the false judgment degree of accuracy of sensor.Therefore, such test mode, is badly in need of improving.
Utility model content
The utility model, for deficiency of the prior art, provides a kind of counterweight test machine, can test out the degree of accuracy of load cell accurately, will greatly reduce error, and the operation of the few test of joint, save the test duration, increase work efficiency.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of counterweight test machine, comprise support, the standard test weight being arranged at the test platform on support and testing, described test platform is provided with mount pad, described mount pad is provided with register pin, described mount pad there is tested sensor by register pin location and installation, described test platform is also provided with hydraulic jack, the piston rod of described hydraulic jack withstands on described tested sensor and is fastened on described mount pad by this tested sensor, described tested sensor front end is connected with connecting link, described connecting link is connected with described standard test weight.
In technique scheme, preferably, described tested sensor is connected with signal conductor, and the data transfer that tested sensor detects by described signal conductor carries out data processing to computing machine.

Accompanying drawing explanation
Fig. 1 is existing tester architecture schematic diagram.
Fig. 2 is tester architecture schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: as shown in Figure 1 to Figure 2, a kind of counterweight test machine, comprise support 1, the standard test weight 2 being arranged at the test platform 11 on support and testing, described test platform 11 is provided with mount pad 12, described mount pad 12 is provided with register pin 32, described mount pad 12 there is tested sensor 3 by register pin 32 location and installation, described test platform 11 is also provided with hydraulic jack 4, the piston rod of described hydraulic jack 4 withstands on described tested sensor 3 and is fastened on described mount pad 12 by this tested sensor 3, described tested sensor 3 front end is connected with connecting link 21, described connecting link 21 is connected with described standard test weight 2.
Described tested sensor 3 is connected with signal conductor 31, and the data transfer that tested sensor 3 detects is carried out data processing to computing machine by described signal conductor 31.
Shown in accompanying drawing 1 is exactly the structure of existing tester architecture, wherein have employed four bolts 13 and is fixedly installed on mount pad 12 by tested sensor 3, convenient test.But this mode, wastes time and energy, and, each bolt 13 tighten after state different, tested sensor 3 can be made overall stressed, uneven, therefore result in the weight that tested sensor 3 detects counterweight 2, have huge deviation.Therefore, this quadrat method will be eliminated.
Shown in accompanying drawing 2 is exactly the tester architecture structure that this device adopts.This device, first utilizes register pin 32 to be determined at the position displacement of mount pad 12 by tested sensor 3, and then, tested sensor 3 is fastened on mount pad 12 by recycling hydraulic jack 4.And then utilize this tested sensor 3 to detect the weight of counterweight 2, like this, can measure the most accurately.Thus maximizedly reduce measuring error, thus the true error scope of tested sensor 3 can be drawn accurately.
This device, installs tested sensor 2 very convenient, only needs tested sensor 2 to be positioned on mount pad 12, after making register pin 32 allocation, restarts hydraulic jack and compresses tested sensor 2.Operator needs to do to obtain action, and only have and place tested sensor 2, remaining can from motion action.Very convenient, save job step.
The data that the tested sensor 2 of this device detects can pass through signal conductor 31, are delivered to computing machine and carry out data processing, by the weight of repeated detection various criterion counterweight, and through calculating, thus obtain the metrical error scope of this tested sensor 3.
Protection domain of the present utility model includes but not limited to above embodiment; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection domain of the present utility model.
The utility model can test out the degree of accuracy of load cell accurately, will greatly reduce error, and the operation of the few test of joint, save the test duration, increase work efficiency.
