The present invention relates to an output torque measurement test apparatus, and more particularly, an output torque test for testing whether or not the output of a drive side operated by a motor, such as a manufactured gas circuit breaker, actually generates the desired output. Relates to a device.

Generally, various circuit breakers, such as a gas circuit breaker, perform the operation | movement, such as the drive part side through a motor blocking a gas valve.

At this time, whether or not the driving unit side that cuts off the gas valve through the motor actually drives the gas valve is determined by the capacity of the motor. In this case, it is preferable to adopt the motor having the most suitable capacity to operate the driving unit. Do.

This is expensive because of the large capacity of the motor is expensive, while the small capacity has a problem that it is difficult to operate the gas valve sufficiently.

Therefore, there is an absolute need for test equipment that can overcome the economic problems by using a motor with the most suitable capacity and also determine whether the gas valve is fully operated.

Accordingly, the present invention has been made to solve the above-mentioned problems and has the following object.

The purpose is to provide a test apparatus that can accurately know whether the opening and closing operation of the gas valve is properly performed through the use of a motor having the most suitable capacity.

Another object of the present invention is to improve the reliability of the product by enabling a prior quality reduction of the product.                         

In order to achieve this purpose, the measurement test results are based on whether or not the rotational driving force of the motor to be manufactured subject to the measurement test can be rotated by the pneumatic pressure supplied separately. It was possible by knowing.

Hereinafter, with reference to the accompanying drawings which are preferred embodiments for carrying out the present invention described above will be described in detail.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Terms to be described later are set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer producing the product, and the definitions should be made based on the contents throughout the present specification.

1 and 2, Figure 1 is a cross-sectional view for showing the configuration of the torque test apparatus according to the present invention, Figure 2 is a cross-sectional view for showing a state of use of the test apparatus according to the present invention As an example, a transfer table 40 for fixing and transporting the measured object P, a tester body portion 1 for testing torque and durability of the transferred measured object, and the transfer table 40 and the tester body It consists of a work bench 50 which supports the part 1.

First, the feed table 40 is composed of a bracket 41 for fixing the workpiece (P) for testing the torque and durability, a fixing die 43 for fixing the bracket 41, and the fixed die The guard rail 42 for moving the 43 to the tester body portion 1 is coupled to the fixed die 43 so as to be slidable.

And, the front portion of the body portion (1) is rotated in engagement with the object to be measured (P) by moving the slide from the guide rail 42 is rotated 10 is configured to interfere with the rotation.

The pivot 10 is composed of a jig 13 and a rotation pad 12 at both ends with respect to the rotation shaft 11.

The control unit 20 is located at the rear end thereof.

The control unit 2 is a brake pad 21 is fixed to the moving bracket 22 by the bolt 24, the moving bracket 22 to the anti-rotation shaft 23 through one coupling bracket (3) It is fixed, the front end of the piston rod 31 is coupled to the central portion of the bracket 22 is configured.

At this time, the rotation pad 12 and the control means 20 is made to be inserted into the case 2, the coupling bracket 3 is coupled to the case 2 by the long bolt 4 at both ends of the case (2). .

And the transfer table 40 and the body portion 1 is installed on the upper end of the work table 50 on the same horizontal line, and the other side of the work table 50 to apply the air pressure to operate the pneumatic cylinder (30) A line (L1) and a line (L2) for supplying or discharging are formed, and a solenoid valve (V) for blocking or opening a flow path of air supplied from the outside is configured, and a switch for operating the solenoid valve (V). It consists of a pressure gauge (G) which is installed so as to check the state of the pressure of the air pressure supplied to (S1) and the pneumatic cylinder (30).

Referring to the state of use and operation of the torque test and durability test device made of the above configuration are as follows.

First, the rotating unit 10 constitutes a drive coupler 44 connected to a motor shaft or a final output shaft of a gear group connected to the motor shaft which rotates by the driving force of the motor of the measured object P which has been manufactured. The jig 13 is engaged.

In this case, the jig 13 receives the output driving force output from the drive coupler 44 by the method of configuring the jig 13 and the drive coupler 44 corresponding to the uneven portion, respectively.

In this state, the switch S1 is turned ON to open a flow path (not shown) of the solenoid valve V. FIG.

By this operation, the outside air is supplied to the pneumatic cylinder 30 through the line L1 while indicating the air pressure supplied to the gauge G.

This air again acts to advance the piston rod 31 forward through the piston 80.

Through this operation, the braking pad 21 moves together with the moving bracket 22 of the control means 20 connected to the piston rod 31 to closely adhere to the rotary pad 12 of the pivot 10.

At this time, the adhesive force that is in close contact with the rotary pad 12 is determined by the air pressure supplied.

In this state, by operating the switch (S2) to supply power to the object to be measured (P) to drive a motor (not shown) constituting it.

A motor group (not shown) configured in the object to be measured P by the supply of such power supplies an operation and a gear group (not shown) connected to a motor shaft (not shown) or a motor shaft (not shown) that rotates by the driving force. Rotating drive coupler 44 connected to the final output shaft (not shown) of the).

At this time, since the driving coupler 44 is coupled to the jig 13 that the rotating unit 10 constitutes, the jig 13 is rotated by the rotation driving force finally transmitted to the driving coupler 44. It can't be rotated or rotated.

That is, when the capacity of the motor (not shown) configured in the object to be measured (P) for rotating the drive coupler 44 is smaller than the air pressure supplied, the motor (not shown) does not rotate. When the capacity of is large, the driving force is transmitted to the jig 13 to rotate the jig 13, and thus the rotation pad 12 will also rotate.

However, although the rotation pad 12 is pressurized by air pressure by the braking pad 21, the braking pad 21 has an anti-rotation shaft 23 coupled to the moving bracket 22 on one side of the coupling bracket 3. Since it penetrates through, the brake pad 21 does not rotate.

Therefore, in this case, the rotation pad 12 is rotated in a state of sliding on the brake pad 21.

By such an operation, a constant load is generated in the motor (not shown) configured in the object to be measured P, which affects a constant voltage meter or a constant voltage meter according to the load generated by the rotation.

As a result, in the present invention, a motor (not shown) configured in a certain object P has to have a driving force greater than or equal to a certain torque in order to drive a third drive such as a gas valve, wherein the third drive is 60 kg, for example. A torque of f is required to be used to test whether a motor (not shown) configured in the measured object P can drive a third drive having a torque of 60 kgf.

This results in a motor configured to the object P to be measured by applying the air pressure of 60 kgf or a slightly higher air pressure to bring the brake pad 21 into close contact with the rotary pad 12. Jig in which a drive coupler 44 connected to a final output shaft (not shown) of a gear group (not shown) connected to a motor shaft (not shown) or a motor shaft (not shown) that rotates in response to a driving force of When rotating (13), the driving force of the motor (not shown) comprised in the to-be-measured object P can measure that it can operate a 3rd drive with the driving force of at least 60 kgf or more.

Thus, this repeated measurement makes it possible to select a motor having the most suitable capacity for any object to drive any third drive, and also the object P to drive any third drive. It can be tested whether it can be done.

After the series of measurements, the switch S1 and the switch S2 are operated to change the flow path of the solenoid valve V to supply air through the line L2 to reverse the piston 80. The operation of the measured object P is stopped, and the back of the moving table 40 is removed to remove it, and then the mounting is performed for the next measurement.

The present invention having such a configuration may be variously modified by those skilled in the art and may take various forms.

It is to be understood, however, that the present invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined in the appended claims. It should be understood to do.

As described above, the test apparatus of the present invention receives the rotational driving force of the motor of the measured object to be manufactured to drive any third drive and the third drive. It is possible to determine the selection of the motor with the most appropriate driving force to make it possible and to measure and test the torque and durability of the rotational driving force of the motor of the finished object to be manufactured so that the quality of the product can be reduced beforehand. There is an effect that can strengthen.
