Embodiment 1

[0061] Embodiment 1, the detailed engineering structure is as follows:

[0062] like figure 1 and figure 2 As shown, the guide rod 30 is made up of a handle 31 and a guide 32, the handle 31 and the guide 32 are cylindrical, the cross-sectional diameter of the handle 31 is smaller than the cross-section diameter of the guide 32, the handle 31 and the guide 32 have a total The axes are fixed together, the handle 31 is clamped by the chuck, and the axis of the handle 31 coincides with the rotation axis of the chuck. The upper part of the body 10 is provided with a guide cavity 11, the guide cavity 11 is preferably a round hole, the guide part 32 of the guide rod 30 can move axially in the guide cavity 11, and there is only a small radial gap between the guide part 32 and the guide cavity 11 , so that the axes of the guide portion 32 and the guide cavity 11 coincide. The elastic element 20 is preferably a coil spring, which is assembled between the lower end surface of the gui...

Embodiment 2

[0067] Embodiment 2, the detailed engineering structure is as follows:

[0068] Will figure 2 The characteristic wheel 41 in the shown embodiment 1 drives the displacement indicating table 50 to cancel the whole set of structure for displaying the displacement, and the pointer 70 is fixedly connected with the claw 40, and the engraved line 16 is fixedly connected with the body 10 to form Figure 11 In the second embodiment shown, the rest of the structure and coordination relationship are consistent with the first embodiment.

[0069] like Figure 12 As shown, the pointer 70 is fixedly connected with the claw 40, and the claw 40 swings, and the pointer 70 also swings along with it; the engraved line 16 is fixedly connected with the body 10; When overlapping, the top of the pointer 70 just points to the engraved line 16.

[0070] Preferably, the outline of the body 10 facing the pointer 70 is provided with a score line 16, and the score line 16 can be fixed on the surface o...

Embodiment 3

[0071] Embodiment three, the detailed engineering structure is as follows:

[0072] Will Figure 11 In the second embodiment shown, the pointer 70 and the engraved line 16 are canceled, the body 10 is fixedly connected with the trigger switch 80, and the corresponding actuating plate 45 is added to the arm of the claw 40 to form a Figure 13 In the third embodiment shown, the rest of the structure and coordination relationship are consistent with the second embodiment.

[0073] like Figure 13 and Figure 15 As shown, the trigger switch 80, the power supply 84 and the prompter 88 (not shown) form a circuit, and the trigger switch 80 is fixedly connected to the body 10. The trigger switch 80 can and can only be in the free state and the free state of the push rod 82. Inwardly compress the conduction within a very small distance, and design different driving circuits, so that the prompter 88 can be driven to make sudden changes in prompts such as sound, light, vibration (for ...

Abstract

The invention discloses a centralizer and a use method, belongs to the field of machining, and particularly relates to a device for assisting in a machine tool or a mechanical arm in looking for the circle center of an object to be machined. The centralizer comprises a body, an elastic element, a guide rod and a claw. The body moves along the axis of the guide rod, and the guide rod and the body trend to move to be away from each other through the elastic element. The claw can swing around an axis fixedly connected to the bottom of the body. Two measurement faces are arranged on the lower portion of the claw. No material is arranged on the area, smaller than 180 degrees, formed by the two measurement faces. A first symmetric face is a face passing through the swing axis of the claw, and the two measurement faces are symmetric about the first symmetric face. When the claw swings to the first symmetric face to coincide with the axis of the guide rod, the centralizer can send signals capable of being recognized. During centering of the centralizer, machine tool measurement equipment is not needed, the error is small, and efficiency is high; and a non-full circle section can be centered, and the problem in the prior art is solved.

Description

technical field [0001] The invention discloses a centering device, which belongs to the field of mechanical processing, and in particular relates to a device for assisting a machine tool or a mechanical arm in finding the center of a workpiece to be processed. Background technique [0002] In the prior art, the drilling machine will pre-adjust the spindle of the machine tool to intersect with the center of the bar before processing the hole features of the cylindrical bar surface through the center of the circle, or milling on the circular surface along the axial direction and milling the keyway features. , the jargon is called alignment. [0003] In the prior art, centering is achieved by fixing the material, then starting the spindle to rotate, the tool is just in contact with both sides of the round bar, recording the distance moved by the tool at the two contact points, and the moving tool is located in the center of the contact point, that is, the centering is completed...
