One of the rotating shafts 101 of the rotating mechanism 10 is coupled to one end of a rotating arm 13 and drives the rotating arm 13 to rotate. One end of the linear motion mechanism 11 is coupled to the other end of the rotary arm 13, and when the rotary arm 13 is rotated, the rotary arm 12 causes the linear motion mechanism 11 to rotate synchronously. The clamp module 12 is connected to the other end of the wire moving mechanism 11 and is used for clamping the control rod of the pipe fitting to be tested of the test to be tested. When the rotating arm 13 is rotated to drive the linear motion mechanism 11 to rotate synchronously, the clamp module 12 is also rotated by the linear motion mechanism 11. In addition, the linear motion mechanism 11 performs linear motion, so the linear motion mechanism 11 drives the clamp module 12 to move linearly.

In addition, the controller 16 determines the number of times the test device 1 repeats the test to test the service life of the pipe fittings.

In addition, the testing device 1 of the present invention may further include a displacement sensor 17 and a torque meter 18.

The displacement sensor 17 can be a potentiometer, which changes one of the interiors according to the rotation of the rotating shaft 101. The resistance value, such that its potential changes, the potentiometer will feedback the potential value to the controller 16, so that the controller 16 knows the amount of rotation of the rotating shaft 101, and thus the angle at which the rotating arm 13 rotates. The above-mentioned potentiometer is only one embodiment of the present invention, and the displacement sensor 17 is not limited to a potentiometer, and other types of displacement sensors can be used. The torque meter 18 is also disposed on the rotating shaft 101, and is electrically connected to the controller 16.

Please refer to the second and third figures together. The second figure is a perspective view of one embodiment of the pipe fittings of the present invention, and the third figure is another embodiment of the pipe fittings of the present invention. Stereoscopic view. As shown in the figure, the pipe fitting to be tested in this embodiment is a composite outlet valve 3, and the composite outlet valve 3 includes a body 30, an outlet pipe 31 and a control rod 32. The control rod 32 is used for controlling the user to rotate, push up or down, and controls a water outlet valve (not shown) inside the body 30 to control the water temperature and flow of the water flowing out of the water outlet pipe 31. A handle 33 is mounted on the control lever 32 of the composite outlet valve 3 for the user to rotate, push up or down the control lever 32.

Please refer to the fourth to seventh figures, which are respectively a flow chart of one embodiment of the test method of the present invention, a schematic diagram of an embodiment of the test object for setting a pipe fitting of the present invention, and a test tube for the test device of the present invention. A schematic diagram of one embodiment of a road component to be tested, and another schematic diagram of an embodiment of the test device of the present invention for testing a pipe fitting.

As shown in the fourth figure, when the test apparatus 1 is testing the pipeline component D, the first step S1 is performed to set the pipeline fitting D4 to the positioning seat 15 of the testing device 1. In the present embodiment, the pipe fitting test object 4 is a composite water outlet valve, but the invention is not limited to the composite water outlet valve. During the test, the pipe fittings to be tested 4 will be further connected with cold and hot water pipes to test whether the pipe fittings to be tested 4 can operate normally.

Thereafter, step S3 is performed to clamp the control rod 41 of the pipe fitting DST 4 by the jig module 12 of the testing device 1. Before the test, the handle of the pipe fitting D4 is first disassembled, so that the jig module 12 grips the control rod 41 of the pipe fitting D4. Next, in step S5, the test condition is set by the controller 16 and the test mode is selected to set the direction, time, angle, and direction and time during which the rotary mechanism 10 drives the rotary arm 13 to rotate, and the linear motion of the control rod 41. That is, the test operation of the test device 1 is determined, and the test mode includes the number of times the test is repeated.

In the present embodiment, the test conditions set by the present invention may include the upper limit value of the torque of the rotation of the rotating mechanism 10 and the upper limit value of the force of the linear motion of the linear motion mechanism 11. When the torque of the rotation of the rotating mechanism 10 or the force of the vertical movement of the linear motion mechanism 11 exceeds the upper limit value of the torque or the upper limit of the force, it means that the test device 1 may be abnormally operated due to mechanical failure or other reasons, or the pipe fittings are waiting. The damage condition has occurred in the object 4, and the controller 16 controls the rotation mechanism 10 and the line motion mechanism 11 to stop the operation to stop the test. In addition, the test conditions include cold and hot water pipe supply cold, hot water temperature and water pressure, and the rotational opening and up and down movement of the pipe fitting D4, that is, the maximum angle of rotation of the pipe fitting D4 With the maximum amount of movement up and down, to avoid excessive left and right rotation and move the control rod 41 up and down, and damage the pipeline fitting D. The above test mode is a test mode for testing the pipe fitting D4, which may correspond to a specification, for example, the US specification is the first test mode, and the European specification is the second test mode. The controller 16 of the present embodiment controls the rotating mechanism 10 and the line moving mechanism 11 according to the selected test mode to test the pipe fitting D. Therefore, the present invention is applicable to the specifications of countries.

After the setting test condition and the selection test mode are completed, the process proceeds to step S7, where the controller 16 controls the rotation mechanism 10 and the line motion mechanism 11 according to the test condition and the test mode to drive the clamp module 12 to rotate and move up and down. The control rod 41 driving the pipe fitting D4 is rotated and moved up and down to test the function and service life of the pipe fitting D4. After the test is completed, step S9 is performed to determine the result, for example, according to the number of repeated tests of the control rod 41, to determine the service life of the test object 4 of the pipeline component, or according to the water output of the pipeline component 4 in the test process, The water temperature is used to judge whether the functionality of the test object 4 of the pipe fitting is complete.

In addition, the present invention can further perform step S2 to position the testing device 1 after the installation of the pipe fitting D4 to the positioning seat 15 of the testing device 1 in this manner, which is to adjust the height of the rotating mechanism 10 at the fixing seat 14, To match the height of the pipe fittings 4 to be tested. Further, the adjustment fixing base 14 is fixed to the position of the positioning seat 15 to match the width of the pipe fitting DART 4, and the rotating shaft 101 of the rotating mechanism 10 corresponds to the control lever 41.

Please refer to the eighth figure, which is a schematic diagram of the action path of an embodiment of the test device fitting test object of the test device of the present invention. The action path of this embodiment corresponds to the previously selected test mode, for example, this action path corresponds to the European specification. Initially, the control rod 41 of the pipe fitting D4 is located at the position L0 (as shown in the fifth figure), that is, in normal use, the handle is in the middle position and the water is closed. Next, the controller 16 controls the line moving mechanism 11 to move the control rod 41 upward to the position L1, that is, to open the pipe fitting D4 and discharge the water. Then, the line moving mechanism 11 drives the control lever 41 to move down to the position L2 (returning to the position of L0), that is, closing the pipe fitting D4 and stopping the water discharge. Thereafter, the controller 16 controls the rotating mechanism 10 to drive the control lever 41 to rotate counterclockwise, which is equivalent to rotating the handle to the right to the position L3, that is, controlling the outlet water temperature to be a low temperature. Then, the line moving mechanism 11 drives the control rod 41 to move up to the position L4 to open the pipe fitting D4 and discharge the water, and the water is cold water. Then, the rotating mechanism 10 drives the control rod 41 to rotate clockwise, which is equivalent to rotating the handle to the left to the position L5. This action is to continuously open the pipe fitting D4 and continue to discharge water, and directly adjust the water temperature to a high temperature. Next, the rotating mechanism 10 drives the control rod 41 to rotate counterclockwise, that is, the handle is rotated to the right to the position L6. This action is to continuously open the pipe fitting D4 and discharge water, and directly adjust the outlet water temperature to a low temperature. Thereafter, the line moving mechanism 11 drives the control lever 41 to move down to the position L7, that is, the pipe fitting DART 4 is closed to stop the water discharge. Thereafter, it is equivalent to turning the handle to the left to the position L8 and moving up to the position L9. Next, it moves down to position L10 and finally to the right to return to the initial position L0, which is a test period.

The above test action path is only one embodiment of the present invention, and the user can select various test modes in step S5 of the fourth figure according to the test requirements, so as to meet the various test actions and action cycles required by the national specifications. .

In addition, the present invention can measure the angle at which the rotating mechanism 10 rotates the rotating arm 13 by the displacement sensor 17, and therefore, after the clamping module 12 clamps the control rod 41 of the pipe fitting DART 4, and sets the test. Before the condition, the control lever 41 can be rotated left and right to the left and right dead point positions (for example, the position L8 and the position L7), and the two potential values measured by the displacement sensor 17 are recorded, and the two potential values respectively represent the control rod. The left and right dead spots of 41 are set as test conditions. The detailed operation is to rotate the control lever 41 clockwise until it can not rotate, and the handle is rotated to the left to the position L8. At this time, the displacement sensor 17 measures a first potential value, that is, sets the first potential value to the left dead point. . Thereafter, the control lever 41 is rotated counterclockwise until it is unable to rotate, and the handle is rotated to the right to the position L7. At this time, the displacement sensor 17 measures a second potential value, that is, sets the second potential value to the right dead point. Subsequently, during the test process, the displacement sensor 17 feedbacks the measured potential value to the controller 16, and the controller 16 compares the feedback potential value with the second potential value according to the set first potential value. And the angular position at which the lever 41 is rotated is judged to avoid excessively rotating the lever 41.

In addition, the controller 16 calculates an average of the first potential value and the second potential value to obtain a third potential value, which is set to an intermediate position, that is, the handle is rotated to the intermediate position. For example, when the handle needs to be rotated from the position L10 to the right to return to the position L0, the controller 16 controls the rotation mechanism 10 to rotate counterclockwise until the potential value returned by the displacement sensor 17 reaches the third potential value to stop the lever. 41 can stop at the intermediate point (position L0).

As can be seen from the above, the test apparatus 1 of the present invention measures the potential value of the control lever 41 rotated to both ends by the displacement sensor 17, and the controller 16 calculates the average of the two to know the potential value of the corresponding intermediate point (position L0). So that the controller 16 can surely control the rotating mechanism 10 to drive the control lever 41 to rotate to the intermediate point. Thus, the rotating mechanism 10 of the present invention can be implemented by using a lower-cost DC motor, that is, the above-described purpose of stopping the control lever 41 at the intermediate point can be achieved without using a costly servo motor or a stepping motor.

In summary, the test device of the pipe fitting of the present invention and the test method thereof can allow the pipe fittings to rotate and move the wire to be tested, so that the pipe fittings can be tested, and the test conditions and test modes can be set. And to achieve a variety of test actions, the number of tests to meet the needs of national standards. In addition, the test device of the present invention is movable, so when the test is performed, the pipe fittings are first set, and then the height and horizontal position of the rotating mechanism of the test device are determined to match the various pipe fittings. Appearance.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and the variations, modifications, and modifications of the shapes, structures, features, and spirits described in the claims of the present invention. All should be included in the scope of the patent application of the present invention.
