Description

Technical Field

[0001] The invention relates to the technical field of testing devices, and in particular to a quality inspection testing device for automobile casting materials. Background Art

[0002] Brake disc is one of many castings in automobiles. There are many types of brake discs, which are characterized by thin walls, and the disc and the center are formed by sand cores. Different types of brake discs have differences in disc diameter, disc thickness and the gap between the two discs. The thickness and height of the disc hub are also different.

[0003] Whether there are cracks on the brake disc surface is an important inspection indicator of the brake disc. If there are cracks on the brake disc surface, the braking efficiency will be reduced, the vibration will increase, and the car body will also shake. In extreme cases, it may also cause the brake disc to break, causing serious safety accidents. Temperature is an important factor affecting the cracking of the brake disc surface;

[0004] When the brake disc is in use, a large amount of heat will inevitably be generated on its surface. If the metal material used to make the brake disc does not meet the requirements for anti-deformation function under high temperature environment, the high temperature will cause deformation or cracking on the surface of the brake disc, affecting the normal use of the brake disc. The existing experimental device for exploring the influence of temperature on the metal material of the brake disc has a low degree of automation and cannot automatically explore the effect of temperature on the performance of the brake disc material. At the same time, it cannot automatically screen out defective brake discs before temperature exploration, and often requires manual inspection and screening, which increases the workload of inspectors. Therefore, a quality inspection test device for automotive casting materials is proposed to solve the above problems. Summary of the invention

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 8 A quality inspection test device for automobile casting materials, comprising a conveying disc 1 for conveying and a driving motor arranged below the conveying disc 1 for intermittently driving the conveying disc 1, a plurality of circumferentially distributed rotating mounting openings 101 are provided at the top of the conveying disc 1, an annular mounting frame 2 for placing a brake disc to be tested is rotatably provided inside the rotating mounting opening 101, a clamping mechanism for clamping the brake disc to be tested is provided on the inner side of the annular mounting frame 2, a driven gear ring 8 is fixedly connected to the bottom end of the annular mounting frame 2, further, the clamping mechanism comprises clamping cylinders 5 circumferentially distributed on the side wall of the annular mounting frame 2, an output end of the clamping cylinder 5 extends to the inner side of the annular mounting frame 2 and is fixedly connected to an arc-shaped clamping plate 4, a material leakage opening is provided at the bottom end of the annular mounting frame 2, and the arc-shaped clamping plate 4 is in an L-shaped structure, which plays a role of clamping and lifting the brake disc to be tested;

[0034] Furthermore, the top end of the storage box 7 is fixedly connected with an arc-shaped driving gear plate 20 which is arranged opposite to and used for driving the driven gear ring 8 to rotate.

[0035] It should be noted that: the clamping cylinder 5 drives the arc-shaped clamping plate 4 to move, so as to realize the clamping and fixing function of the brake disc material before the temperature exploration. When the conveying disc 1 drives the annular mounting frame 2 to move to the arc-shaped driving tooth plate 20, the driven gear ring 8 is meshed with the arc-shaped driving tooth plate 20. At this time, under the action of the circular motion of the annular mounting frame 2, the driven gear ring 8 rolls along the arc-shaped driving tooth plate 20, and drives the annular mounting frame 2 fixed on its top to rotate. The annular mounting frame 2 drives the brake disc material to be tested fixed on its inner side to rotate, so that the detection needle 12 can move along the surface of the brake disc material to be tested, so as to realize the detection function of the surface cracks and deformation of the brake disc material before the temperature exploration. The cracks and deformation on the surface of the brake disc material can be detected and screened out before the temperature exploration, so as to avoid the defective products caused by the processing technology affecting the results of the temperature exploration of the deformation resistance and cracking resistance of the brake disc material.

[0036] Reference Figure 2-Figure 4 A rotating arm 6 is rotatably provided at the top of the conveyor disc 1. The rotating arm 6 is composed of an L-shaped rotating rod 601 and a movable sleeve 602. The movable sleeve 602 is slidably provided on the surface of the L-shaped rotating rod 601. An electric push rod 24 is provided inside the movable sleeve 602. One end of the electric push rod 24 is fixedly connected to the inner wall of the movable sleeve 602, and the other end of the electric push rod 24 is fixedly connected to one end of the L-shaped rotating rod 601.

[0037] It should be noted that: every time the brake disc to be tested rotates one circle, the electric push rod 24 drives the movable sleeve 602 to move once, so as to ensure that the detection needle 12 has a comprehensive detection function on the surface of the material of the brake disc to be tested.

[0038] A plurality of sliding through holes are evenly arranged inside the movable sleeve 602, a connecting shaft is arranged inside the sliding through hole, an upper conductive column 11 is fixedly connected to the top end of the connecting shaft, a lower conductive column 13 is fixedly connected to the bottom end of the connecting shaft, and a detection needle 12 is fixedly connected to the bottom end of the lower conductive column 13; further, electrode sheets 14 are arranged on the inner wall of the sliding through hole, an auxiliary block 16 is fixedly connected to the surface of the detection needle 12, the auxiliary block 16 is fixedly connected to the side wall of the rotating arm 6 through a connecting spring 17, a controller 9, a current sensor 10 and a power supply 15 are installed on the side wall of the rotating arm 6, and the current sensor 10 is used to receive the current signal emitted by the power supply 15.

[0039] It is worth noting that the tip of the detection needle 12 is a spherical structure to prevent the tip of the detection needle from being stuck inside the crack and unable to move out.

[0040] It is worth noting that: the electrode sheets 14 on one side inside each sliding through hole are arranged in parallel and connected to the negative pole of the power supply 15, and the electrode sheets 14 on the other side are arranged in parallel and connected to the current sensor 10, and one end of the current sensor 10 is connected to the positive pole of the power supply 15 through a wire; the current sensor 10 establishes a signal transmission connection with the controller 9, and the controller 9 controls the operation of the clamping cylinders 5 at various locations.

[0041] It is worth noting that: when the controller 9 receives the feedback signal from the current sensor 10, the controller 9 controls the clamping cylinder 5 to work, and the clamping cylinder 5 drives the arc-shaped clamping plate 4 to move, thereby clamping and fixing the brake disc to be tested. When the controller 9 receives the feedback signal from the current sensor 10 again, the controller 9 controls the clamping cylinder 5 to work, so that the arc-shaped clamping plate 4 releases the clamping and fixing of the brake disc to be tested.

[0042] It is worth noting that: when the brake disc to be tested is placed inside the annular mounting frame 2, the clamping cylinder 5 drives the arc-shaped clamping plate 4 to move closer to the center of the annular mounting frame 2 to achieve clamping and fixing of the brake disc to be tested;

[0043] When the clamping cylinder 5 drives the arc clamping plate 4 away from the brake disc to be tested, the circle formed by the arc clamping plates 4 is larger than the leakage opening at the bottom end of the annular mounting frame 2, ensuring that unqualified brake discs can fall into the storage box 7 through the leakage opening.

[0044] It should be noted that: before the brake disc to be tested is heated, when the detection needle 12 moves to the crack or concave-convex part on the surface of the brake disc to be tested, it indicates that the processing technology of the brake disc to be tested is unqualified, and the detection needle 12 will correspondingly fall or rise (when the detection needle 12 moves to the flat surface of the brake disc to be tested, the connecting spring 17 is in a compressed state, when the detection needle 12 moves to the concave part or the crack, the detection needle 12 moves downward under the elastic force of the connecting spring 17, and when the detection needle 12 moves to the convex part, the convex part will lift the detection needle 12), so that the upper conductive column 11 or the lower conductive column 13 moves to the inside of the sliding through hole and connects with the two The side electrode sheet 14 is in contact, so that the power supply 15 can supply power to the current sensor 10. The current sensor 10 receives the current and feeds back a signal to the controller 9. The controller 9 controls the clamping cylinder 5 at the current sensor 10 that has fed back the signal to work, so that the arc clamping plate 4 is away from the brake disc to be tested, so that the brake disc material with deformation defects caused by the process falls inside the process defect recovery area 701 for recovery, so that the brake disc material can be automatically detected and screened before the temperature exploration, avoiding the defective products caused by the processing technology affecting the exploration results of the temperature on the deformation resistance and cracking resistance of the brake disc material.

[0045] It is worth noting that the staff's workstation is located in the good product recovery area 702 inside the storage box 7. Every time the driving motor drives the conveyor disc 1 to rotate 1 / N intervals (N is the number of annular mounting frames 2), the rotation will be paused for a period of time to facilitate the staff to take out the qualified brake disc inside the annular mounting frame 2, and place a new brake disc to be tested inside the annular mounting frame 2.

[0046] The top of the conveyor disc 1 is fixedly connected with an L-shaped support rod 23 near the annular mounting frame 2, and one end of the L-shaped support rod 23 is fixedly connected with a heating ring 3 for heating the brake disc to be tested, and an electromagnetic induction heating coil 19 is arranged inside the heating ring 3. A negative pole power connection rail 22 and a positive pole power connection rail 21 that are in electrical contact with the sliding power connection block 18 are fixedly connected between the two ends of the storage box 7. Furthermore, a pair of wire passing grooves are opened inside the L-shaped support rod 23, and a wire passing hole aligned with the wire passing grooves is opened inside the conveyor disc 1. Both ends of the electromagnetic induction heating coil 19 extend to the bottom of the conveyor disc 1 through the wire passing grooves and the wire passing holes, and both ends of the electromagnetic induction heating coil 19 are fixedly connected with the sliding power connection block 18.

[0047] It is worth noting that the negative electrode power connection slide rail 22 and the positive electrode power connection slide rail 21 are respectively connected to the external power source 15.

[0048] It should be noted that: as the conveyor disc 1 continues to rotate, when the sliding power blocks 18 on both sides slide to the inner side of the positive power connection slide rail 21 and the negative power connection slide rail 22 respectively, the external power supply 15 supplies power to the electromagnetic induction heating coil 19 through the negative power connection slide rail 22 and the positive power connection slide rail 21, so that the electromagnetic induction heating coil 19 heats the brake disc to be tested. Before the sliding power blocks 18 on both sides are separated from the positive power connection slide rail 21 and the negative power connection slide rail 22, the electromagnetic induction heating coil 19 can heat the brake disc to be tested to 150°C, simulating the high temperature generated by friction of the brake disc material during actual use. Subsequently, under the action of the detection needle 12, the brake disc material in a high temperature state can be subjected to crack detection and deformation detection, thereby automatically exploring the influence of temperature on the deformation resistance and crack resistance of the brake disc material.

[0049] Furthermore, a support ring is rotatably provided at the bottom end of the conveyor disc 1 to play a supporting role, thereby preventing the driving motor from bearing weight.

[0050] Furthermore, a storage box 7 is provided below the conveyor tray 1 , and a relatively arranged partition is fixedly connected to the interior of the storage box 7 , and the partition divides the interior of the storage box 7 into a process defect recovery area 701 , a good product recovery area 702 and a material defect recovery area 703 .

[0051] It should be noted that brake disc materials that have deformation defects and crack resistance defects due to the process are recycled in the process defect recovery area 701, brake disc materials that have insufficient deformation resistance and qualified crack resistance in high temperature environment are recycled in the material defect recovery area 703, and good products are recycled in the good product recovery area 702.

[0052] The present invention requires a worker to stand at a workstation (the workstation is located at the good product recovery area 702 inside the storage box 7), and the worker is required to place the brake disc to be tested inside the annular mounting frame 2, control the opening of the clamping cylinder 5, and the clamping cylinder 5 drives the arc-shaped clamping plate 4 to move toward the center of the annular mounting frame 2 to clamp and fix the brake disc to be tested, and then manually rotate the rotating arm 6 so that the bottom end of the detection needle 12 on the rotating arm 6 is placed on the detection surface of the brake disc to be tested;

[0053] When the driving motor drives the conveyor disc 1 to rotate, the conveyor disc 1 drives the annular mounting frame 2 to make a clockwise circular motion (refer to Figure 1 In the direction of the annular mounting frame 2, the brake disc to be tested fixed on the inner side of the annular mounting frame 2 is driven to make a circular motion. During the rotation, when the driven gear ring 8 is meshed with the arc-shaped driving tooth plate 20, the driven gear ring 8 will rotate under the action of the arc-shaped driving tooth plate 20, thereby driving the annular mounting frame 2 fixed on its top to rotate. The annular mounting frame 2 drives the brake disc to be tested clamped and fixed on its inner side to rotate, so that the detection needle 12 moves on the surface of the brake disc to be tested. When crack resistance or deformation resistance defects appear on the surface of the brake disc to be tested, the end of the detection needle 12 will rise or fall under the action of the defect. At this time, it means that the brake disc to be tested has cracks or unevenness on its surface due to unqualified processing technology, and the detection needle 12 will fall or rise accordingly (when the detection needle 12 moves to the flat surface of the brake disc to be tested, the connecting spring 17 is in a compressed state. When the detection needle 12 moves to a concave or cracked place, the connecting spring 1 7, the detection needle 12 moves downward under the action of the elastic force. When the detection needle 12 moves to the protrusion, the protrusion will lift the detection needle 12), so that the upper conductive column 11 or the lower conductive column 13 arranged above the detection needle 12 moves to the inside of the sliding through hole and contacts with the electrode sheets 14 on both sides, so that the power supply 15 can supply power to the current sensor 10. The current sensor 10 receives the current and feeds back a signal to the controller 9. The controller 9 controls the clamping cylinder 5 at the current sensor 10 that has fed back the signal to work, so that the clamping cylinder 5 drives the arc-shaped clamping plate 4 fixed at its output end away from the brake disc to be tested, so that the brake disc material with deformation defects and crack resistance defects caused by the process falls to the inside of the process defect recovery area 701 for recovery, so that the brake disc material before the temperature exploration can be automatically detected and screened out, so as to avoid the defective products caused by the processing technology affecting the exploration results of the temperature on the deformation resistance and crack resistance of the brake disc material;

[0054] Every time the brake disc to be tested rotates one circle, the electric push rod 24 drives the movable sleeve 602 to move intermittently, so as to ensure the comprehensive detection function of the detection needle 12 on the surface of the material of the brake disc to be tested;

[0055] For the brake disc material to be tested with qualified process, when the detection needle 12 moves on its surface, no lifting movement will occur, and thus the clamping cylinder 5 will not be triggered, so that the brake disc material with qualified process continues to be clamped and fixed on the inner side of the annular mounting frame 2. As the annular mounting frame 2 continues to make a circular motion with the conveying disc 1, when the sliding power connection block 18 connected to the bottom end of the electromagnetic induction heating coil 19 slides to the inner side of the positive power connection slide rail 21 and the negative power connection slide rail 22 respectively (at this time, the driven gear ring 8 is separated from the arc-shaped driving gear plate 20, and the brake disc material no longer rotates ), the external power supply 15 supplies power to the electromagnetic induction heating coil 19 through the negative power rail 22 and the positive power rail 21, so that the electromagnetic induction heating coil 19 heats the brake disc material to be tested inside the annular mounting frame 2 (the brake disc material to be tested here is a brake disc material to be tested with qualified technology). Before the sliding power blocks 18 on both sides are separated from the positive power rail 21 and the negative power rail 22, the electromagnetic induction heating coil 19 can heat the brake disc material to be tested to 150°C, simulating the high temperature generated by friction of the brake disc material during actual use;

[0056] After the sliding power block 18 connected to the bottom end of the electromagnetic induction heating coil 19 is separated from the positive power rail 21 and the negative power rail 22, the electromagnetic induction heating coil 19 stops heating the brake disc material to be tested. Subsequently, the driven gear ring 8 fixedly connected to the bottom end of the annular mounting frame 2 is meshed with the arc-shaped driving gear plate 20 on the other side, so that the driven gear ring 8 drives the annular mounting frame 2 at its top to rotate, and then the annular mounting frame 2 continues to drive the brake disc material to be tested that is clamped and fixed inside to rotate. At this time, the detection needle 12 detects cracks and concave and convex surfaces of the heated brake disc material to be tested (the detection method is the same as described above). If there are cracks or concave and convex surfaces on the surface of the heated brake disc material to be tested, it means that the deformation resistance and cracking resistance of the brake disc material in a high temperature environment are unqualified, then the clamping cylinder 5 controls the arc-shaped clamping plate 4 to separate from the brake disc material to be tested, so that the brake disc material to be tested falls into the material defect recovery area 703 for recovery;

[0057] Brake disc materials with qualified anti-deformation and anti-cracking properties in high-temperature environments will rotate with the annular mounting frame 2 to the position above the good product recovery area 702, that is, the staff's workstation, and the staff will take it down and place it in the good product recovery area 702 for recycling. At the same time, new brake disc materials to be tested can be placed on the inside of the annular mounting frame 2. The above operations are repeated to automatically explore the influence of high temperature on the anti-deformation performance of the brake disc material, ensuring that the brake disc will not have crack defects and deformation defects after high-temperature operation.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
