Abstract
The utility model provides a clamp which is used when a sensor is fixed on a vibration table to carry out an analog experiment. The clamp comprises a flange seat, a reinforcing rib and a sensor fixing flange disc. The clamp adopts a high end and low end design, the low end is provided with 5 mounting holes which are in threaded connection with the sensor fixing flange disc, the other high end of the flange seat is provided with 4 mounting holes which are in threaded connection with the sensor fixing flange disc, the reinforcing rib is arranged between each mounting hole and a mounting surface, and the mounting surface is connected with the vibration table through bolts. The clamp for sensor analog vibration experiments enables the number of the sensor analog vibration experiments to be increased to 9 each time from 1 each time, enables the original vibration amplifying amount to be reduced to 0.5 times from 2 times and enables the experiment efficiency to be enhanced by 3 times.
Description
Technical field:
The utility model relates to a kind of anchor clamps, specifically, is a kind of anchor clamps that use when carrying out simulation test on the bumper that sensor is fixed on.
Background technology:
Sensor applications is extensive, and is of a great variety, as is used for the pressure transducer of gaging pressure, is used for the liquid level sensor of measuring liquid level, is used for the speed pickup of measuring speed, is used to temperature sensor of measuring temperature or the like.But concerning the liquid level sensor and temperature sensor that are used for the aircraft use, technical requirement and performance index are unusual.The influence of vibration when particularly aircraft these two kinds of sensors in practical flight will afford flight.So selected liquid level sensor and temperature sensor must be done the vibration simulation test in process of production on shaking table, just make the vibrational state of shaking table simulated flight device, sensor is installed on the shaking table works, under vibrational state, whether reach technical requirement on design with test liquid level sensor and temperature sensor.
Generally speaking, sensor is when doing the analog vibration experiment, adopt test fixture as shown in Figure 1, by the steel flanges dish of 38 millimeters thick, and a joist steel be welded to form, because surface of contact was little when this anchor clamps were connected with shaking table, cause the resonance of anchor clamps and shaking table easily, increased the vibration amplification quantity, had a strong impact on the precision of test.In addition, this anchor clamps can only be tested three products at every turn, inefficiency, can not satisfy growing demand sensor far away supplies with, because aircraft uses the task of sensor to increase year by year in recent years, the production of sensor also will increase product quantity except quality improves, so improve sensor production efficient and reduce cost of products, the vibration amplification quantity of limiting sensor when doing the analog vibration experiment.Most important, it directly determines the index of bearing vibration of sensor.Because the vibration condition of shaking table is to design according to state of flight fully.Desirable vibration test fixture be on shaking table, make product vibrational state near in the designing technique condition given vibrational state.Vibratory output is not done any amplification.Just vibrate amplification quantity and approach zero.
Summary of the invention:
Approach zero in order to solve sensor vibration amplification quantity when doing the analog vibration experiment, improve test efficiency simultaneously, the utility model proposes a kind of anchor clamps that are used for the Sensor Analog Relay System vibration test, these anchor clamps are by flange seat, reinforcement 3, the sensor fixed flange is formed, described flange seat adopts high low side design, low side is provided with 5 mounting holes 1, be spirally connected with the sensor fixed flange, another high-endly is provided with 4 mounting holes 2 flange seat, be spirally connected with the sensor fixed flange, described reinforcement 3 is arranged between each mounting hole and the installed surface, and installed surface is connected with bumper by screw.
Owing to adopted a kind of anchor clamps that are used for the Sensor Analog Relay System vibration test that the utility model proposes, make the sensor vibration test, be reduced to 0.5 times by 2 times of original vibration amplification quantity.Test efficiency improves 3 times.Aspect production efficiency, test 170 sensors, save test fee more than 30,000 yuan, save labour cost (with per hour 30 yuan of calculating of labour cost): (171/3-171/9) * and 30 * 3=3420 unit, save at least about 33820 yuan every year by such estimation.
Description of drawings:
Fig. 1 is former test fixture structural representation
Fig. 2 is the utility model structural representation
Fig. 3 is the utility model trystate structural representation
Embodiment
Fig. 1 is former test fixture structural representation, and Fig. 2 and Fig. 3 are structural representations of the present utility model, and implementation method can be passed through explanation as shown in Figures 2 and 3.As seen from the figure, when working, reach effective weight balancing in order to solve anchor clamps, reduce possible resonance, flange seat adopts high low side design, low side is provided with 5 mounting holes 1, be used for the installation test sensor, the threaded hole that screw adopts the spring swivel nut is installed, is spirally connected with the sensor fixed flange, another high-endly is provided with 4 mounting holes 2 flange seat, also be to be used for the installation test sensor, the threaded hole that screw adopts the spring swivel nut equally is installed, is spirally connected with the sensor fixed flange, sensor passes mounting hole, so once just can test 9 sensors, the intact back of vibratory test efficient when dismounting effectively improves.
And for example shown in Figure 2, each flange and fixed installation face support by reinforcement, so just contact with installed surface to have formed 9 reinforcements 3.Effectively reduced because the transverse vibration that the height of anchor clamps causes.Reduced the vibration amplification quantity, installed surface is connected with shaking table with screw by fixed orifice, and its area design makes installed surface utilize the shaking table installed surface to greatest extent, to reduce because vibration table contacts issuable resonance with device.
As shown in Figure 3, select casting aluminium material for use, the vibration test fixture installed surface is fixed on the simulating vibration table sliding table by fixed orifice, then 9 sensors is passed 9 flange holes of vibration test fixture, be fixed on the test fixture with the ring flange of M6 screw at last sensor.Begin to do vibration test.And according to the table top physical size of shaking table, utilize slide unit table top gib screw to greatest extent, the vibration tong plane is done greatly as far as possible, the wall thickness of the mounting flange of test unit is increased to 25mm from original 8mm, can increase the rigidity of anchor clamps like this, off-test, dismounting attachment screw, change sensor and detect, off-test.
