step 1: quantitatively taking a plurality of metal ingots, putting the metal ingots into a smelting furnace for smelting, skimming slag after smelting, exhausting by adopting a high-purity nitrogen exhaust method, and then draining water for casting to obtain a rod-shaped substrate, wherein the metal ingots comprise the following components in percentage by mass: 5.0 to 10.0 percent of zinc, 3.5 to 7.5 percent of yttrium, 2.0 to 3.0 percent of niobium, 1.0 to 1.5 percent of zirconium, 0.5 to 0.8 percent of chromium, 0.05 to 0.15 percent of molybdenum and the balance of iron;

the production equipment of the high-wear-resistance transmission gear of the automobile gearbox comprises a high-precision bar cutting device and a flatness and thickness intelligent detection device; the flatness and thickness intelligent detection device comprises a flat thickness detection part and two positioning conveying parts, wherein the flat thickness detection part is used for detecting whether the distance between end surfaces and the flatness of two sides of a gear are changed, the two positioning conveying parts are respectively positioned at the front end and the rear end of the flat thickness detection part and respectively play a role in vertically aligning and feeding the gear into the flat thickness detection part and a role in feeding the gear with thickness detection from the flat thickness detection part.
As shown in fig. 8, the high-precision bar cutting device comprises a clamping and conveying part 34 fixedly arranged and used for clamping and conveying a bar-shaped substrate, a cutting part 35 fixedly arranged and used for cutting the bar-shaped substrate, a force unloading part used for supporting the front end of the bar-shaped substrate and a control part used for controlling driving parts in the clamping and conveying part 34, the cutting part 35 and the force unloading part to operate, wherein the force unloading part comprises a force unloading base 36, a force unloading cylinder 37 fixedly arranged on the upper side of the force unloading base 36, and a force unloading part 38 fixedly arranged on the upper end part of a piston rod of the force unloading cylinder 37, and an arc-shaped bayonet 39 which is always in radian with the outer ring of the bar-shaped substrate is arranged at the upper end of the force unloading part 38.
Before each cutting, the force unloading part moves the force unloading part 38 to the upper part under the action of the control part, so that the arc-shaped bayonet 39 of the force unloading part 38 clamps the front end part of the rod-shaped base material from the bottom, and the shearing force in the process that the cutting blade of the cutting part 35 cuts the rod-shaped base material from top to bottom can be overcome, because one side of the rod-shaped base material is clamped and fixed by the clamping part 34, the other side of the rod-shaped base material is directly cut by the cutting blade, the shearing force is generated between the cutting blade and the clamping part 34, and the phenomenon that the flatness of the end face of the cutting process is inclined is caused, and the shearing force effect can be removed to a certain extent by supporting the rod-shaped base material from the side of the rod-shaped base material, which is opposite to the clamping part 34, through the force unloading part 38.
Specific structures and principles of the flatness and thickness intelligent detecting device are described below.
The specific description is as follows: in order to facilitate the technical means, a large number of brackets (particularly a detection bracket and a driving bracket) which are easy to block the part vision are hidden in the drawing of the intelligent flatness and thickness detection device, and because the two positioning and conveying components are positioned at the front end and the rear end of the flat and thickness detection component, only one positioning and conveying component is left in order to embody the drawing conveniently.
The present invention also includes, for ease of understanding, the fixing member (an object fixed relative to the support), the rotating member (an object rotatable relative to the support or the sliding member), and the sliding member (an object linearly movable relative to the support) in the drawings, wherein brackets are added to the original basic reference numerals and are additionally marked A, B, C, respectively, for example, 1 (a) indicates that the component with the reference numeral 1 belongs to the fixing member, so as to facilitate observation.
The following references to lateral directions refer to left and right directions horizontal to the ground, vertical directions refer to front and rear directions horizontal to the ground and perpendicular to the lateral directions, and vertical directions refer to directions perpendicular to the ground, and they may be expressed by X-axis, Y-axis, and Z-axis in a three-dimensional coordinate system.
As shown in fig. 1 and 2, the flat thickness detecting component comprises a detecting bracket fixedly arranged, a transverse sliding rail 1 fixedly arranged on the detecting bracket, two groups of movable setting frames 2 transversely symmetrically arranged on the transverse sliding rail 1 in a sliding manner, two groups of movable measuring frames 3 respectively transversely 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 identifying and detecting mechanism for identifying whether the spacing between the two measuring wheels 4 accords with a standard, and a preset adjusting mechanism for adjusting the spacing between the two groups of movable measuring frames 3;
the preset adjusting mechanism comprises a bidirectional adjusting screw 5, the front half section and the rear half section of the bidirectional adjusting screw 5 are respectively a positive thread and a reverse thread with consistent attribute specifications, a positive screw hole and a reverse screw hole are respectively arranged in the height alignment of the two groups of movable setting frames 2, and the front half section and the rear half section of the bidirectional adjusting screw 5 are respectively in threaded butt joint with the two groups of movable setting frames 2;
a plurality of detection sliding holes are formed in the movable setting frame 2, a detection sliding rod is fixedly arranged on one side, aligned with the detection sliding holes, of the movable measuring frame 3, the detection sliding rod is arranged in the detection sliding holes in a sliding mode, a detection elastic piece 6 is sleeved on the detection sliding rod, and two ends of the detection elastic piece 6 are respectively fixed on the movable setting frame 2 and the movable measuring frame 3.
Besides the function of conveying the gears, the positioning conveying component has an important function of correcting the gears, so that the gears can be automatically positioned before being conveyed to the flat thickness detecting component, and the gears are reasonably detected by the flat thickness detecting 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 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 the step 6, 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 positioning and 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 the step 6, 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 with respect to the stepping wheel 24 in the positioning and 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 the step 6, 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.
