As shown in fig. 1 and 2, the thickness intelligent detection device of the gear processing apparatus includes a thickness detection part for detecting whether the distance between end surfaces on both sides of a gear is changed, and two conveying parts which are respectively located at the front end and the rear end of the thickness detection part and which function to vertically align the gear into the thickness detection part and function to send out the gear, for which the thickness detection has been completed, from the thickness detection part;
the thickness detection component comprises a detection bracket fixedly arranged, a transverse sliding rail 1 fixedly arranged on the detection bracket, two groups of movable setting frames 2 transversely symmetrically and slidingly arranged on the transverse sliding rail 1, two groups of movable measuring frames 3 respectively transversely and symmetrically movably arranged on the two groups of movable setting frames 2, two measuring wheels 4 respectively vertically and freely rotatably arranged on the two groups of movable measuring frames 3, an identification detection mechanism for identifying whether the distance between the two measuring wheels 4 accords with the standard, and a preset adjusting mechanism for adjusting the distance between the two groups of movable measuring frames 3;

Besides the function of conveying the gears, the conveying component has an important function of correcting the gears, so that the gears can be automatically positioned before being conveyed to the thickness detection component, and the gears are reasonable when being detected by the thickness detection component.
Because the thickness specifications of different gears are different, a preset adjusting mechanism is needed to be used for detecting a plurality of different gears, the preset adjusting mechanism can adjust the movable setting frame 2 to a proper position, the position of the movable setting frame 2 represents the position of the movable measuring frame 3 in the natural state of the detecting elastic piece 6, and the design purpose is to adjust the initial preset position of the movable setting frame 2.
The operation method comprises the following steps:
step 1: selecting a gear after machining, manually measuring the thickness of two end surfaces of the gear by adopting a vernier caliper, selecting different angles for 5-8 times, recording numerical values after each measurement, and entering the next step if all the numerical values are the same, otherwise, judging that the flatness requirement of the gear does not reach the standard and marking the gear as a disqualified piece;
step 2: putting the gear into a conveying part at the input end, automatically aligning the gear passing through the conveying part, and automatically feeding the gear into a thickness detection part;
step 3: observing and identifying the dynamic state of the detection mechanism from the moment when the gear enters the thickness detection component, and recording the situation;
step 4: the gear after passing through the thickness detection part automatically enters the conveying part of the output end, and then the gear is automatically sent out from the conveying part of the output end and is taken down;
step 5: and (3) judging the observation of the identification detection mechanism according to the step (3), if the identification detection mechanism gives out an alarm of unqualified gear flatness, marking the gear as an unqualified product, otherwise, repeating the steps (2), 3 and 4) for 3-5 times, and if the identification detection mechanism does not give out an alarm of unqualified gear flatness after multiple times of circulation, judging the gear as a qualified product.
The recognition detection mechanism plays a vital role in the device, an operator judges whether the thickness (actually flatness) of the gear meets the standard according to the reading of the recognition detection mechanism, and the applicant designs various forms in the recognition detection mechanism:
the first form employs the visual detection principle:
as shown in fig. 3 and 4, the identification detection mechanism comprises a visual detection contact 7, a visual detector 8, an adjustment scale bar 9 and a width adjuster, wherein the visual detection contact 7 is provided with two bottoms which are respectively and downwards fixedly arranged on two groups of movable measurement frames 3, the visual detector 8 is provided with two adjustment gears 14 which are respectively and slidably arranged on the transverse slide rail 1, the adjustment scale bar 9 is fixedly arranged on the detection support and is parallel to the two visual detectors 8, the adjustment scale bar 9 is provided with a graduated scale, the width adjuster comprises an extension block 10 fixedly arranged on the transverse slide rail 1, two groups of opposite rods 11 transversely fixedly arranged on the detection support, two groups of width adjustment rods 12 which are respectively and transversely slidably arranged on the two groups of opposite rods 11, the two groups of width adjustment rods 12 are respectively and fixedly arranged on the two visual detectors 8, the extension block 10 is rotationally provided with an adjustment rod 13, notches for exposing the adjustment gears 14 are respectively and slidably arranged on the upper side and the lower side of the extension block 10, the width adjustment rods 12 are symmetrically arranged along the center of the adjustment rods 13, and the two groups of width adjustment rods 12 are meshed with the adjustment gears 14.
In step 5, the act of identifying the unqualified warning of the gear flatness sent by the detection mechanism is as follows: during the intelligent detection of the thickness of the gear wheel, the visual detector 8 detects one or more times the behaviour of the visual detection feeler 7 directly above it.
Before the detection, the two visual detectors 8 are adjusted to a proper position through the width adjuster (the proper position is that after the measuring wheel 4 is extruded and sprung by the gear with standard specification, the visual detectors 8 detect that the visual detection contact 7 is just above the visual detection contact), and the left-right movement distance of the two visual detectors 8 is completely consistent in the adjustment process due to the design of the adjusting gear 14 and the double adjusting racks adopted by the width adjuster, which corresponds to the symmetrical design of the two measuring wheels 4. Then, when the gear is fed between the two measuring wheels 4, the visual detection feeler 7 performs a positional shift because the two measuring wheels 4 are pressed and sprung apart, and if the gear is qualified and the surface thereof has no tilting phenomenon, then when the gear is fed between the two measuring wheels 4, the two visual detection feelers 7 always detect that the two visual detection feelers 7 are just above them respectively, and if the gear has a thickness variation at a position or positions, at least one visual detection feeler 7 does not detect the visual detection feeler 7 for a certain time, and the operator can judge that the gear flatness and thickness deviation are unqualified from "the behavior of the visual detector 8 has one or more times and does not detect the visual detection feeler 7 above it".
The second form uses the principle of friction:
as shown in fig. 5, the identification and detection mechanism includes two limiting drivers 15 fixedly disposed on the two movable measuring frames 3, the two limiting drivers 15 respectively butt-joint with the two measuring wheels 4 and drive the two measuring wheels 4 to perform the same-speed phase inversion, the friction force of the gears received by the two measuring wheels 4 is opposite to the stepping direction of the gears, but the friction force benefit of the measuring wheels 4 to the gears is insufficient to change the conveying component to continuously drive the gears to step forward, the gears and the two measuring wheels 4 generate slipping phenomenon, and a speed sensor for detecting the rotation speed of the gears is disposed in the limiting drivers 15.
In step 5, the act of identifying the unqualified warning of the gear flatness sent by the detection mechanism is as follows: the speed sensor detects that the rotational speed of the restriction drive 15 is not a constant mean value range, and one or more times the rotational speed of the restriction drive 15 is detected to be too slow or too fast.
The measuring wheel 4 itself has a power of rotation and this power of the measuring wheel 4 gives the reverse thrust of the gear (a force opposite to the stepping direction of the gear), but the surface of the measuring wheel 4 is smoother than the stepping wheel 24 in the conveying member, so that the reverse thrust of the gear given by the automatic process of the measuring wheel 4 does not have a suppressing effect on the stepping of the gear. Based on the above premise, after the measuring wheel 4 is extruded by the gear, because the pressure becomes large, the friction force which hinders the rotation of the measuring wheel 4 also becomes large, and if the thickness and the inclination flatness of the gear change, the distance between the two measuring wheels 4 also changes slightly, and finally the tangential pressure given by the gear to the measuring wheels 4 is changed, and the friction force of the rotation of the measuring wheels 4 is changed. Therefore, when the operator finds that the "the rotation speed of the restriction driver 15 is not a constant average value range, there are cases where the rotation speed of the restriction driver 15 is detected too slow or too fast one or more times, which is caused by the flatness and thickness variation of the gears.
The design function of the limiting driver 15 is not used for limiting the stepping of the gear, but is used for limiting the stepping of the gear so as to provide different rotating speeds, and the information source of the rotating speeds can be used for judging whether the flatness and the thickness of the gear change.
The third form employs the principle of energized contact:
as shown in fig. 6 and 7, the identification detection mechanism includes a signal lamp 16 with a battery, two insulating sliding bases 17 slidably disposed on the transverse sliding rail 1, two first power transmission rods 33 fixedly disposed at bottoms of the two groups of movable measurement frames 3 respectively, a second power transmission rod 18 is fixedly disposed on the insulating sliding bases 17, the two first power transmission rods 33 are connected through a first power transmission wire 19, the two second power transmission rods 18 are connected through a second power transmission wire 20, the signal lamp 16 is located on a line where the second power transmission wire 20 is located, and the first power transmission rods 33 and the second power transmission rods 18 can be in contact and butt joint in the sliding process of the movable measurement frames 3.
In step 5, the act of identifying the unqualified warning of the gear flatness sent by the detection mechanism is as follows: in the process of intelligently detecting the thickness of the gear, the signal lamp 16 has one or more flickering conditions.
Before the detection, the two insulating carriages 17 are adjusted in advance to the proper position (the proper position is that after the measuring wheel 4 is extruded and sprung by a gear with standard specification, the two first through-holes 33 are just respectively connected with the two second through-holes 18 in an opposite way). Then, when the gear is fed between the two measuring wheels 4, because the two measuring wheels 4 are pressed and sprung, the first through-air lever 33 moves along with the movable measuring frame 3, if the gear is qualified, the surface of the gear is not inclined, then when the gear is fed between the two measuring wheels 4, the two first through-air levers 33 are just respectively opposite to the two second through-air levers 18, so that the whole line is completed, the signal lamp 16 is constant, if the gear has a condition that the thickness of the gear changes at one or more positions, at least one first through-air lever 33 is separated from the second through-air lever 18 and staggered within a certain time, so that the signal lamp 16 is extinguished, and an operator can judge that the deviation of the flatness and the thickness of the gear is unqualified according to the condition that the signal lamp 16 has one or more flashes.
