Problems solved by technology
[0002] When the machine tool is tapping, the contact of the micro switch needs to keep in contact with the cam, and the cam is easy to jam the contact of the micro switch in the process of reciprocating forward and reverse rotation, resulting in damage to the micro switch, resulting in replacement of the micro switch during the production process. The switching frequency is high, which increases the cost and reduces the production efficiency

Embodiment
[0009] Embodiment: A tapping micro switch protection device, the tapping micro switch includes a micro switch 1 and a cam 2, and the contact 11 of the micro switch 1 can elastically move a set distance along the direction of the line connecting the micro switch 1 with the cam axis There is a contact block 3, one side of the contact block 3 is hinged with the contact point 11 of the micro switch, the other side of the contact block 3 can elastically stop on the surface of the cam 2, and the contact block 3 elastically stops on the cam during use 2 surface, the cam 2 rotates positively and negatively during use, and the contact block 3 will automatically adjust with the cam 2 around its hinged position with the contact point 11 of the micro switch according to the different contact positions, so that the contact block 3 is always in contact with the cam The surface is in fully movable contact, which effectively prevents the bad situation of the contact point from being stuck due ...

The invention discloses a protective device of a tapping microswitch. The tapping microswitch contains a microswitch and a cam, wherein the contact of the microswitch can move a preset distance elastically along the direction of the line between the contact and the axis of the cam; the protective device is provided with a contact block; and one side of the contact block is hinged with the contact of the microswitch and the other side of the contact block can be against the surface of the cam elastically. When the protective device of the invention is used, the contact block is still against the cam elastically; and the contact block can rotate with the cam and perform automatic rotation and adjustment around the hinging position with the contact of the microswitch, thus the contact surface can be effectively increased, the problem that the contact of the microswitch is easy to wear can be solved, the service life of the microswitch can be prolonged, the replacements of fittings can be reduced and the production efficiency can be increased.
Description
technical field [0001] The invention relates to a protection device, in particular to a protection device for a tapping micro switch. Background technique [0002] When the machine tool is tapping, the contact of the micro switch needs to keep in contact with the cam, and the cam is easy to jam the contact of the micro switch in the process of reciprocating forward and reverse rotation, resulting in damage to the micro switch, which causes the micro switch to be replaced during the production process. The switching frequency is high, which increases the cost and reduces the production efficiency. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a tapping micro switch protection device, the tapping micro switch protection device is simple in structure, easy to use, not easy to damage, and reduces the cost. [0004] The technical solution adopted by the present invention to solve its technical problems: a tapping micr...
