Description
Technical field
The utility model relates to a kind of main shaft detecting structure coordinated with proximity switch.
Background technology
In mechanical field, usually through the rotation of main shaft, carry its tools rotates, thus cutter can be utilized to process workpiece.At present, for the ease of detecting tool changing state and the operating condition of main shaft, often needing to be provided with on main shaft to detect position accordingly, detecting for corresponding sniffer.If but the situation that this detection position occurs wearing and tearing or damages, then need to change whole main shaft, thus cause the wasting of resources.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of main shaft detecting structure coordinated with proximity switch, it is by being arranged on detecting on nut by outward flange, breach, and detection nut is bolted on pull bar, if the situation that breach, outward flange occur wearing and tearing or damage, nut is detected by dismantling and changing, and without the need to changing whole main shaft, thus can saving resource.
For solving the problem, the technical scheme that the utility model adopts is as follows:
The main shaft detecting structure coordinated with proximity switch, be provided with the pull bar that can rotate along with it, and this pull bar can move up and down by relative main in described main shaft; The lower end of described pull bar is provided with the pulling claw assembly for clamping handle of a knife; This main shaft detecting structure comprises the detection nut being bolted on pull bar upper end, and the upper end of described detection nut is provided with the cylindrical portion in hollow form, and the left and right sides of this cylindrical portion all offers breach, and described breach is formed as the detected object of proximity switch; The periphery wall of described detection nut is also provided with the outward flange extended along its circumferencial direction, and described outward flange is formed as the detected object of proximity switch.
Described detection nut is bolted on pull bar by three, and these three bolts arrange around the circumference of pull bar; The axis of described bolt and the axis being parallel of pull bar.
The lower end of described detection nut is provided with location division, described location division is provided with the locating slot embedded for pull bar upper end.
Compared to existing technology, the beneficial effects of the utility model are:
The utility model is by being arranged on detecting on nut by outward flange, breach, and by detection nut is bolted on pull bar, if the situation that breach, outward flange occur wearing and tearing or damage, nut is detected by dismantling and changing, and without the need to changing whole main shaft, thus can saving resource; And the processing detecting nut is simple and convenient, and it is convenient to install, and can reduce costs; In addition, its by with the coordinating of proximity switch, operator judges main shaft duty according to the output signal of proximity switch can be convenient to.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
Wherein, 1, nut; 11, breach; 12, outward flange; 3, bolt; 4, pull bar.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further, understands the utility model technical thought required for protection so that clearer.
As shown in Figure 1, 2, be the main shaft detecting structure coordinated with proximity switch of the present utility model, the pull bar 4 that can rotate along with it is installed in described main shaft, and this pull bar 4 can move up and down by relative main under external force; The lower end of described pull bar 4 is provided with the pulling claw assembly for clamping handle of a knife; This main shaft detecting structure comprises the detection nut 1 being fixed on pull bar 4 upper end by bolt 3, the upper end of described detection nut 1 is provided with the cylindrical portion in hollow form, the left and right sides of this cylindrical portion all offers breach 11, and described breach 11 is formed as the detected object of proximity switch; The periphery wall of described detection nut 1 is also provided with the outward flange 12 extended along its circumferencial direction, described outward flange 12 is formed as the detected object of proximity switch.
Described detection nut 1 is fixed on pull bar 4 by three bolts 3, and these three bolts 3 arrange around the circumference of pull bar 4; The axis of described bolt 3 and the axis being parallel of pull bar 4, with by said structure, can, while improving the fastness detecting nut 1 installation, also be convenient to install.
Preferably, the lower end of described detection nut 1 is provided with location division, described location division is provided with the locating slot embedded for pull bar 4 upper end, to be convenient to the installation location detecting nut 1, can improve the installation effectiveness detecting nut 1.The middle part of described detection nut 1 is also provided with through hole.
In actual use, can judge that described main shaft is in running or halted state by utilizing the testing result of proximity switch to the breach 11 detecting nut 1, it is specific as follows: when the speed of mainshaft is higher, detecting nut 1 can along with pull bar 4 High Rotation Speed, proximity switch can export lasting high potential, to represent that main shaft is in operating condition; And when main shaft stops gradually, proximity switch constantly exports height two current potentials, until finally continue to remain on some current potentials (high potential or electronegative potential), thus represent that main shaft is in halted state.And when main shaft is in exchanging knives process, pull bar 4 drives pulling claw assembly relative main to move up and down, and detecting nut 1 and can move along with pull bar 4, thus, by utilizing proximity switch to the testing result of outward flange 12 detecting nut 1, main shaft tool changing state can be judged.
The utility model is by being arranged on detecting on nut 1 by outward flange 12, breach 11, and by detection nut 1 is arranged on pull bar 4 by bolt 3, if the situation that breach 11, outward flange 12 occur wearing and tearing or damage, nut 1 is detected by dismantling and changing, and without the need to changing whole main shaft, thus can saving resource; And the processing detecting nut 1 is simple and convenient, and it is convenient to install, and can reduce costs; In addition, its by with the coordinating of proximity switch, operator judges main shaft duty according to the output signal of proximity switch can be convenient to.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
