Description
Technical Field
The invention relates to a lever induction meter for detecting the position degree of an electromagnet assembly, belonging to the technical field of manufacturing and assembling of sealed relays.
Background
As shown in fig. 1, the electromagnet assembly 101 is a very important component in a sealed relay, and the riveting quality (the combination form of the iron core 1011 and the magnetic pole riveting part, the deformation degree of the riveting part, the position degree between parts in the assembly after riveting, and the like) of the assembly and the consistency of the size of the assembly after riveting directly affect the assembly quality of the subsequent process of the product, and are related to the technical performance and the operation reliability of the whole product. In actual assembly, the length of the electromagnet assembly 101 is easy to guarantee, and the consistency is good, but the long pole 1012 usually has a hook or a head, and the parallelism cannot meet the requirement shown in fig. 1. These two conditions will affect the quality of the assembly shown in figure 2 in different ways. That is, when the long magnetic pole 1012 hooks, the deflection angle of the armature in the armature movable reed assembly 201 and the working air gap between the armature and the long magnetic pole 1012 are reduced, so that the contact pressure between the movable contact 2011 and the stationary contact is small or no pressure exists, and the product is not released; when the long pole 1012 rises, the deflection angle of the armature and the working air gap between the armature and the long pole 1012 increase, which results in a small gap between the movable contact 2011 and the stationary contact and a large attracting voltage or even no work.
In order to make the riveted electromagnet assembly 101 meet the parallelism requirement of fig. 1, a common method is to clamp the working end of the long magnetic pole 1012 by using a flat tongs, forcibly push one end of the short magnetic pole 1013 to correct, make the angle β of the long magnetic pole 1012 slightly change, mount the long magnetic pole working face 10121 and the short magnetic pole working line 10131 by using a knife edge ruler, and observe whether the knife edges of the long magnetic pole working face 10121 and the knife edge ruler are completely attached to judge that the technical requirement of the electromagnet assembly 101 is met. By doing so, the following disadvantages and risks exist: (1) the technical requirements are difficult to meet through one-time correction and observation, and the operation can be successful through repeated operation; (2) the condition of the gap is observed by using a knife edge ruler, although the condition is visual, the measurement error is large, quantification cannot be realized, and the influence of human factors is large; (3) the long magnetic pole working face is repeatedly clamped by using flat tongs, so that the long magnetic pole working face is easily damaged to different degrees; (4) repeated correction easily causes poor combination of the long magnetic pole and the riveted part of the iron core, sometimes causes loosening phenomenon, and needs to be riveted for the second time.
Disclosure of Invention
The invention aims to solve the problems, and a more ideal correction and detection mode is sought, so that the following requirements are met: 1. the long magnetic pole working face is ensured not to be damaged in the correction process to the maximum extent; 2. the riveting position of the iron core and the two magnetic pole rivets is in a non-stressed state in the component correction, and the component is prevented from loosening after being corrected; 3. in the correction process, the deformation degree and the detection result of the component are quantized and visualized, and the correction value of the component can be adjusted timely according to the detection result; 4. the work efficiency of correction, detection is improved, reduces operator's intensity of labour. The positioning, stress and detection conditions of the assembly in the correction and detection are shown in FIG. 3:
in order to ensure that the working surface of the long magnetic pole is not damaged in the correction process, the working surface of the long magnetic pole is firstly attached to a positioning surface A of a clamp, then pressure F1 is applied to the back surface of the working surface, the electromagnet assembly is fixed in the clamp, the height difference between the lowest point (working line) of the short magnetic pole and the positioning surface A is monitored by a lever induction meter to represent the flatness of the working surface of the magnetic pole and the working line of the short magnetic pole, and if the monitored value is greater than the parallelism value shown in figure 1, a pushing force F2 or a pulling force F3 is applied to the riveting end (the area shown in figure 3) of the long magnetic pole according to the direction shown by an indicator of the induction meter until the monitored value of the assembly meets the technical requirements of figure 1 under the condition that the assembly is not.
In order to achieve the purpose, the invention adopts the following technical scheme:
an electromagnet assembly detection and correction device comprises a base 1, a locking knob 2, a guide block a3, a pressing tongue 4, a spring ejecting ball 5, a support 6, an adjusting knob 7, a guide block b8, a push-pull rod 9, a push-pull claw 10, a reference limit seat 11, a lever induction meter 12, a meter head clamp seat 13 and a limit seat 14;
