Problems solved by technology

[0002] The working principle of the thermal relay is that the current flowing into the heating element generates heat, which causes the bimetal sheets with different expansion coefficients to deform. When the deformation reaches a certain distance, the push rod is pushed to move, so that the control circuit is disconnected, so that the contactor When the power is off, the main circuit is disconnected to realize the overload protection of the motor, and the elastic force value of the push rod is the main production technical parameter of the push rod assembly. Stable, resulting in a low pass rate, becoming the bottleneck of relay production

Embodiment 1

[0033] see Figure 1 to Figure 4 , a device for testing the elasticity of a relay push rod assembly of the present invention includes a workbench, which is installed on the workbench and is used to accommodate the control assembly 1 of the push rod assembly 100, the clamping assembly 2 and the force measuring assembly 3, and the control assembly 1 is used When the push rod assembly 100 is energized, the clamping assembly 2 is used to limit the control assembly 1 on the workbench, and the force measuring assembly 3 is used to test the resistance force of the push rod assembly 100 to external contacts.

[0034] The workbench is provided with a limiting blind slot for accommodating the control assembly 1 , and the control assembly 1 is provided with a power terminal 11 protruding into the limiting blind slot and supplying power to the push rod assembly 100 .

[0035] The force measuring assembly 3 is slidably connected to the workbench, and the force measuring assembly 3 is provi...

Embodiment 2

[0048] Please refer to Figure 5 , the force-measuring component 3 is provided with a stopper 311 , the workbench is provided with a screw micrometer 312 , and the threaded rod of the screw micrometer 312 is used to limit the stopper 311 .

[0049] Specifically, the main difference between this embodiment and Embodiment 1 is: a screw micrometer 312 is installed on the mounting plate 42, and a stopper 311 is installed on the workbench, and the screw micrometer 312 and the mounting plate 42 move relative to the workbench. After reaching a certain range, the stopper 311 limits the position movement of the screw micrometer 312 to realize the stability and standardization of the test.

[0050] The rest of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of relay detection, and particularly relates to a relay push rod assembly elasticity testing device. The relay push rod assembly elasticity testing devicecomprises a workbench, a control assembly which is arranged on the workbench and used for accommodating a push rod assembly, a clamping assembly and a force measurement assembly, wherein the control assembly is used for energizing the push rod assembly, the clamping assembly is used for restricting the control assembly on the workbench, and the force measurement assembly is used for testing a resistance force of the push rod assembly for an external contact. The beneficial effects are that a relay push rod assembly to be detected is placed on the clamping assembly of the workbench, the controlassembly energizes the push rod assembly, the force measurement assembly tests the resistance force of the push rod assembly for the contact, and whether the resistance force is within a set value range or not is detected through a displayed value, so that the detection process is simplified and standardized, the external artificial interference in the detecting process is reduced, and the product qualification rate is improved.

Description

technical field [0001] The invention relates to the technical field of relay detection, and in particular discloses a device for testing the elasticity of a relay push rod assembly. Background technique [0002] The working principle of the thermal relay is that the current flowing into the heating element generates heat, which causes the bimetal sheets with different expansion coefficients to deform. When the deformation reaches a certain distance, the push rod is pushed to move, so that the control circuit is disconnected, so that the contactor When the power is off, the main circuit is disconnected to realize the overload protection of the motor, and the elastic force value of the push rod is the main production technical parameter of the push rod assembly. Stability, resulting in a low pass rate, has become a bottleneck in relay production. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the pr...
