Embodiment 1

[0053] Example one, detailed engineering structure:

[0054] According to the introduction of the basic principle structure above, the present invention designs a detailed engineering structure.

[0055] Such as Figure 4 with Figure 5 As shown, the body 1 is made of insulating material, preferably plastic, and is provided with a cavity for accommodating the elastic element 3 and the head 22 of the push rod 2. The side of the cavity of the body 1 is provided with an opening. The size of the opening of the cavity is The operating space for the push rod 2 to be assembled in the guide hole 12 is satisfied. This opening is covered by the side plate 13 which is fixedly connected to the body 1.

[0056] The bottom of the cavity of the body 1 is provided with a guide hole 12, and the rod 21 of the push rod 2 moves along the axis of the guide hole 12. Preferably, the guide hole 12 is a round hole, the rod 21 is a cylinder, and the guide hole 12 and the rod 21 are There is a slight gap betw...

Embodiment 2

[0062] Example two, detailed engineering structure:

[0063] Such as Image 6 As shown, on the basis of the first embodiment above, the upper end opening of the retaining sleeve 6 is changed to be fixedly connected to the rod 21 of the push rod 2, and the elastic force of the retaining sleeve 6 is required to be less than the elastic force of the elastic element 3. When the first contact When the object 8 pushes the first contact 5 to move upward, the third contact 221 and the fourth contact 4 are still in contact.

[0064] Control method of application position switch:

[0065] The premise is that the position switch body 1 is fixedly connected to the stationary second limit object, and the first limit object 8 extends along a fixed track to approach or move away from the second limit object. The control goal is to make the first limit object 8 accurate Stop at a certain distance from the second limiter, that is, stop the first limiter 8 at the target position accurately.

Abstract

The invention discloses a location switch and a control method applying the switch, and belongs to the field of the mechanical location control. The location switch comprises a body, a push rod, an elastic element, a first contact point, a second contact point, a third contact point, a fourth contact point and a retaining bushing; a cavity is arranged in the body, a guiding hole is arranged at thebottom of the cavity, and the push rod slides along an axial direction of the guiding hole; the fourth contact point is arranged on the upper end surface of the guiding hole, and a third contact point is arranged at the head of a push rod, and the elastic element enables the third contact point to contact with the fourth contact point; the second contact point is arranged at the lower end of therod, and the second contact point is only electrically connected with the third contact point, and the first contact point is arranged below the second contact point; the retaining bushing has the elasticity, and the first contact point and the second contact point are free from contact pointing when the retaining bushing is free from the external force; the retaining bushing can deform by itselfwhen being acted by the external force, so that the first contact point and the second contact point can mutually close until to contact. The problem that the regression setting location is inaccuratein the prior art is solved.

Description

Technical field [0001] The invention discloses a position switch, which belongs to the position control field of 3D printers, numerical control machine tools, industrial robots and mechanical design. Background technique [0002] In the prior art, 3D printers, numerically controlled machine tools and mechanical moving parts all require movement to a specific precise position. Take a 3D printer as an example. Before the 3D printer works, the controller must first move the sliders of each axis to the set origin position according to the set direction, that is, make the nozzle at the origin position. In order to identify the origin position, the prior art uses micro To identify the switch, specifically, fix the micro switch at the set position of the track. When the slider on the track moves to the set direction, it will push the trigger point of the micro switch to send a switch signal to the controller, and the controller receives The movement of the slider is stopped immediately...
