Detailed Description
The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.
The utility model relates to a testing device which can be used for rapidly configuring different constant load tensile forces and accurately measuring various parameters, so that the testing requirements of electric cylinders, steering engines and the like can be met.
FIG. 1 shows a front view of the test apparatus of the present invention. Referring to fig. 1, the test apparatus of the present invention includes a test platform 1 and a load support 7 at one end of the test platform 1.
The testing platform 1 is provided with a magnetic grid ruler 2, a tension and pressure sensor 3 and a first pulley 6. The upper end of the load support 7 is provided with a second pulley 8, and the setting height of the second pulley 8 is greater than that of the first pulley 6.
Wherein, the magnetic grid ruler 2 is used for realizing the measurement of displacement. The tension and pressure sensor 3 is used for measuring tension or pressure.
One end of the magnetic grid ruler 2 is connected with a tested device through a first steel wire rope 4, and the other end of the magnetic grid ruler is connected with one end of the tension and pressure sensor 3 through a second steel wire rope 10. The other end of the tension and pressure sensor 3 is connected with one end of a third steel wire rope 11. The third steel wire rope 11 passes around the first pulley 6 and the second pulley 8, and the other end of the third steel wire rope 11 is connected with a balancing weight 9. Through the first pulley 6 and the second pulley 8, the vertical movement of the counterweight 9 can be changed into the horizontal movement of the magnetic grid ruler 2, the tension and pressure sensor 3 and the like.
Preferably, the first pulley 6 is mounted on the test platform 1 through a mounting bracket 5 such that the lowermost end of the first pulley 6 is in contact with the third wire rope 11. In this way, the first pulley 6 can be better mounted on the test platform 1.
Figure 2 shows an end view of the load carrier portion of the test apparatus of the present invention. As shown in fig. 2, the load bracket 7 is preferably provided with a vertical guide rail 14. The counterweight 9 passes through the vertical guide rail 14 and can move up and down along the vertical guide rail 14.
More preferably, two vertical guide rails 14 are arranged on the load bracket 7. The other end of the third steel wire rope 11 is connected with the middle part of the counterweight 9, and the two vertical guide rails 14 are positioned at two sides of the third steel wire rope 11. Therefore, when the third steel wire rope 11 drives the counterweight block 9 to move up and down, the counterweight block 9 can move along the vertical guide rail 14, so that the counterweight block is more stable, and the phenomena of drift and the like can not occur.
In the present invention, preferably, a data processor 12 is further disposed on the testing platform 1. The magnetic grid ruler 2 and the pull pressure sensor 3 are respectively connected with the data processor 12 through a data line 13. Thus, the data measured by the magnetic grid ruler 2 and the pull pressure sensor 3 are sent to the data processor 12, and the data processor 12 can obtain the data such as torque, pull thrust, speed, acceleration, position, angle and the like.
Wherein the above data can be obtained by storing the corresponding calculation formula in the processor 12, and therefore, the present invention does not relate to the improvement of the program.
The following describes how the testing device of the present invention works in detail by taking the test of the electric cylinder and the steering engine as an example.
When testing the electric cylinder, as shown in fig. 1, the cylinder body of the electric cylinder a is fixed on the test platform 1 through the electric cylinder fixing member B, and the output shaft of the electric cylinder a is locked with the other end of the first steel wire rope 4.
Thus, when the electric cylinder A reciprocates, the counterweight 9 is driven to work against gravity, and because the friction coefficient of the first pulley 6 and the second pulley 8 is small, the pulling force of the electric cylinder A is approximately equal to the gravity of the counterweight 9. If the load tension needs to be changed, only the corresponding balancing weight needs to be reassembled.
Meanwhile, when the electric cylinder reciprocates, the head of the magnetic grid ruler 2 is driven to displace so as to obtain displacement data, and tension data is obtained through the tension and pressure sensor 3. The data processor 12 collects data of the magnetic grid ruler 2 and the pull pressure sensor 3 at the same time, and then inputs the weight of the balancing weight 9, so that data of push-pull force, speed, acceleration, position and the like of the electric cylinder can be obtained through calculation.
In a similar way, when the steering engine is tested, the steering engine is locked on the test platform 1 through the steering engine fixing part, the output shaft of the steering engine is locked on the steering wheel through the screw, and then the steering wheel is connected with the other end of the first steel wire rope 4.
When the steering engine reciprocates, the balancing weight 9 is driven to complete four-quadrant operation (forward rotation drives the balancing weight to do work, forward rotation brakes the balancing weight, reverse rotation drives the balancing weight to do work, and reverse rotation brakes the balancing weight). Because the friction coefficient of the first pulley 6 and the second pulley 8 is small, the torsion of the steering engine is approximately equal to the gravity of the counterweight 9. If the torsion needs to be changed, only the rudder disks with different radiuses or the balancing weights with different weights need to be reassembled.
Meanwhile, when the steering engine reciprocates, the ruler head of the magnetic grating ruler 2 is driven to displace so as to obtain displacement data, and tension data is obtained through the tension and pressure sensor 3. The data processor 12 collects the data of the magnetic grating ruler 2 and the pull pressure sensor 3 at the same time, and then inputs the radius of the rudder disk and the weight of the balancing weight, so that the data of the steering engine such as torque, speed, acceleration, position/angle and the like can be obtained.
The testing equipment can obtain different constant torque or load pressure by changing the weight of the balancing weight, so that the testing of the electric cylinder, the steering engine and the like is more convenient. And the data of the magnetic grid ruler and the pull pressure sensor are read by the data processor, and various parameters such as torque, pull thrust, speed, acceleration, position, angle and the like can be measured by the conventional calculation formula, so that the test is more complete.
The above examples of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes and modifications which are obvious to the technical scheme of the utility model are covered by the protection scope of the utility model.
