Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, the embodiment of the present invention discloses a condition monitoring system for a production line, which can be used to detect the coaxiality between a part 30 to be processed and a drill 40 and adjust the coaxiality between the two, wherein the part 30 to be processed is installed on a processing device such as a common drilling machine or a drilling and milling center, the processing device comprises a first installation mechanism 62, a second installation mechanism 61, a third installation mechanism, and a drill 40, the drill 40 is installed on the third installation mechanism, and the drill 40 is installed in a fixed manner, i.e. the drill 40 cannot be radially adjusted before, during and after drilling the part 30 to be processed. Specifically, the monitoring system includes: a sleeve-shaped body 10, a first non-contact detection module and a second non-contact detection module. Wherein, the sleeve-shaped body 10 is mounted on the first mounting mechanism 62, the first mounting mechanism 62 can make the sleeve-shaped body 10 move in three radial directions so as to adjust the position of the axis, thus, the sleeve-shaped body 10 and the drill 40 can meet the required coaxiality by adjusting the radial position so as to make the coaxiality meet the machining precision requirement, and when the part 30 to be machined is drilled, the head of the part 30 to be machined is positioned in the sleeve-shaped part; the first non-contact module is used for detecting whether the coaxiality of the drill bit 40 and the sleeve-shaped body 10 meets the requirement or not; and the second non-contact detection module is used for detecting whether the coaxiality of the drill bit 40 and the sleeve-shaped body 10 meets the requirement or not. Specifically, the second non-contact detection module comprises three distance sensors 51 and a second processing controller 72, the three distance sensors 51 are uniformly arranged on the inner hole wall of the sleeve-shaped body 10, correspondingly, three inverse wave plates 52 are correspondingly arranged on the outer peripheral surface of the drill 40, the three distance sensors 51 respectively emit electromagnetic waves 53 towards the three inverse wave plates 52 and recover the electromagnetic waves 53 generated by the inverse wave plates 52, so as to obtain three distance values; the second processing controller 72 is electrically connected to the three distance sensors 51 and the first mounting mechanism 62, respectively, the second processing controller 72 is configured to obtain three distance values, and perform a difference operation on the three distance values to obtain distance deviations of the three distance values, when the calculated distance deviation is greater than a preset value, which indicates that the drill 40 is not located at a center position that is required to be allowed, that is, the coaxiality between the drill 40 and the sleeve-shaped body 10 does not meet the precision requirement, the second processing controller 72 controls the first mounting mechanism 62 according to the deviation degree and the deviation direction, so that the sleeve-shaped body 10 is adjusted toward a direction in which the coaxiality meets the requirement, and the coaxiality between the sleeve-shaped body 10 and the drill 40 meets the requirement. The first non-contact detection module comprises three light ray transceiving groups and a first processing controller 71, wherein each light ray transceiving group comprises a light ray generator 21 and a light ray receiver 22; the light receiver 22 is used for receiving the light emitted by the light generator 21; the light rays emitted by the three light ray generators 21 in the three light ray receiving and sending groups form a triangle 23, the circle center of an inscribed circle is positioned at the axis of the sleeve-shaped body 10, and the diameter of the inscribed circle is equal to or larger than the diameter of the peripheral surface of the processed part 30; whether the coaxiality of the processed part 30 and the sleeve-shaped body 10 is consistent or not is judged according to the condition of the light received by the three light receivers 22. The specific judgment method is divided into two types. One of them is: the diameter of the inscribed circle of the triangle 23 is only slightly larger than the diameter of the outer peripheral surface of the processed part 30, specifically, the diameter difference between the inscribed circle and the outer peripheral surface is slightly smaller than the maximum value required for coaxiality, the cross section of the light ray is a circle, the diameter of the circle is smaller than the diameter difference between the inscribed circle and the outer peripheral surface (namely the first comparative diameter), in this case, whether the machined part 30 and the sleeve-shaped body 10 meet the requirement of coaxiality is judged according to whether the light receiver 22 receives the light, that is, when all three light receivers 22 are capable of receiving light, it can be considered that the coaxiality of the processed part 30 and the sleeve-like body 10 is satisfactory, when there is a light receiver 22 that fails to receive light, it indicates that the light is blocked by the machined part 30, thus, the coaxiality of the machined part 30 and the sleeve-shaped body 10 is not satisfactory, and the sleeve-shaped body 10 needs to be adjusted to meet the coaxiality requirement. The other mode is as follows: the diameter of the inscribed circle of the triangle 23 is larger than the diameter of the outer peripheral surface of the processed part 30, specifically, the diameter difference between the inscribed circle and the outer peripheral surface is far larger than the maximum value required for coaxiality, the cross section of the light ray is a circle, the diameter of the circle is far larger than the diameter difference (second comparative diameter) between the inscribed circle and the outer peripheral surface, and whether the processed part 30 and the sleeve-shaped body 10 meet the requirement for coaxiality or not is judged according to the area of the light ray received by the light ray receiver 22; when the difference between the areas of the light received by the three light receivers 22 exceeds the predetermined deviation value, it indicates that the coaxiality between the sleeve-shaped body 10 and the part 30 is not satisfactory, and the position of the part 30 needs to be adjusted. Both of the above two ways are judged and controlled by the first process controller 71. For example, in the first mode, the first process controller 71 is configured to obtain a signal indicating whether the light receiver 22 receives light, and when the first process controller 71 does not receive a signal from one of the light receivers, it indicates that the light receiver 22 does not receive light, and at this time, the first process controller 71 controls the second mounting mechanism 61 to adjust the position of the part 30 to be machined so as to meet the requirement of coaxiality; for another example, in the second mode, the first processing controller 71 is configured to receive area receiving signals of three light receivers 22, so as to obtain area values, and compare the area values with each other and preset deviations, and when the difference is greater than the preset deviation, the requirement that the processed part 30 and the sleeve-shaped body 10 are not coaxial is indicated, so that the position of the processed part 30 needs to be adjusted to meet the requirement.
It should be noted that: the distance between the sleeve-shaped body 10 and the machined part 30 is adjusted by the following modes: the direction to be adjusted is decomposed into the direction consistent with the movable direction of the mounting mechanism, and the movement displacement is correspondingly decomposed, so that the sleeve-shaped body 10 and the part 30 to be processed can be moved to the position meeting the coaxiality requirement through the first mounting mechanism 62 and the second mounting mechanism 61.
The invention enables the processed part 30 and the drill 40 to meet the coaxiality requirement in a non-contact mode, and the operation is simpler compared with a contact type adjusting mode, and the coaxiality with higher requirement can be met.
It should be noted that: the present invention uses the sleeve-shaped body 10 as a medium for calibrating the coaxiality between the workpiece 30 and the drill 40, that is, the coaxiality between the drill 40 and the workpiece 30 is judged and adjusted by judging and adjusting the coaxiality between the drill 40 and the sleeve-shaped body 10 and the coaxiality between the workpiece 30 and the sleeve-shaped body 10.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
