Detailed Description

Exemplary embodiments of the present utility model are described in detail below with reference to the attached drawings. The exemplary embodiments described below and illustrated in the drawings are intended to teach the principles of the present utility model to enable one skilled in the art to make and use the present utility model in a number of different environments and for a number of different applications. The scope of the utility model is therefore defined by the appended claims, and the exemplary embodiments are not intended, and should not be considered, as limiting the scope of the utility model. Moreover, for ease of description, the dimensions of the various elements shown in the figures are not necessarily drawn to actual scale, and references to orientation, such as upper, lower, left, right, top, bottom, etc., are based on the orientation or positional relationship shown in the figures, merely to facilitate description of the utility model and simplify description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the utility model. Like elements are denoted by like or similar reference numerals throughout the drawings. Conventional structures or local constructions will be omitted when they may cause confusion or unaware of an understanding of the present disclosure. The order and numerical values of the components and assembly steps set forth in the embodiments do not limit the scope of the present utility model unless specifically stated otherwise.

An on-machine knuckle aperture detection device 10 is generally composed of a shank 1, a body 2 (also referred to as a main body), a first contact microsensor 3, a second contact microsensor 4, a third contact microsensor 5, and a fourth contact microsensor 6.

The shank 1 is a standard for connecting a spindle (not shown) of a machine tool, and different models can be selected to adapt to different machine tools, such as model numbers HSK63A, BT40, etc. The tool shank may also be referred to as a spindle, and is commonly referred to as a tool shank because it may follow the standard interface of a conventional tool with the spindle of a machine tool.

One end side of the body 2 is mounted on the shank 1 by means of heat shrinkage. Preferably, the method comprises the steps of. A plurality of contact micro sensors are uniformly distributed along the circumferential direction on the other end side of the body 2 away from the tool shank 1.

Each touch type microsensor is a commercially available product, and has a mounting hole 9 for mounting and a contact 11 for detection as shown in fig. 5, where fig. 5 (a) is a front view, fig. 5 (B) is a side view, and fig. 5 (C) is a top view.

In this way, the first contact type microsensor 3, the second contact type microsensor 4, the third contact type microsensor 5, and the fourth contact type microsensor 6 can be mounted on the body 2 by bolts through the mounting holes 9. The radial projecting amounts of the sensors from the outer peripheral surface of the body 2 may be arbitrarily set as required, for example, uniformly arranged with the contact apexes on the same circumference.

In actual use, the device 10 is firstly placed on a calibration ring gauge for calibration, and the device 10 is installed in a tool magazine of a machine tool after the calibration is completed.

And then the machine tool performs feeding processing, and after the detection hole is processed, the machine tool spindle returns to the tool changing position, and at the moment, the device is automatically installed on the machine tool spindle under the control of a numerical control program. The numerical control program controls the machine tool spindle to extend into the hole 8 of the machined workpiece 7 with the device (as shown in fig. 3). At this time, the first contact type micro-sensor 3, the second contact type micro-sensor 4, the third contact type micro-sensor 5 and the fourth contact type micro-sensor 6 are respectively contacted with the inner wall of the hole 8, after the first contact type micro-sensor 3, the second contact type micro-sensor 4, the third contact type micro-sensor 5 and the fourth contact type micro-sensor 6 are used for detecting and outputting data, whether the aperture is qualified and is in a state close to the upper and lower difference or not is judged, if the aperture is qualified and the size is in the median value, the next machining is carried out at this time, the main shaft returns to the position, the device is returned to the tool magazine, and then the next machining tool is replaced for machining; if the part is unqualified, automatically stopping the machine tool, alarming, unloading the part by an operator, and analyzing the unqualified reason; if the size is qualified but is near the upper and lower difference, the numerical control program is automatically compensated, and then the cutter changing operation of 'qualified and size is in the median' is performed, so that the machining is performed. The above actions are repeated for each processing cycle.

Thus, on-machine detection of at least part of the plurality of knuckle holes can be realized, and when detection is needed, one device can be compatible with the detection of the aperture with a certain range, and the aperture is determined according to the selected sensor range; if the aperture phase difference to be detected is too large, a plurality of tool shanks with different sizes can be arranged according to the requirement, namely, a plurality of devices for on-machine detection of the knuckle aperture of the tool shanks with different sizes are arranged.
