Description

Technical Field

[0001] The invention relates to the technical field of automobile parts detection, and in particular to a diaphragm spring quality detection device. Background Art

[0002] The diaphragm spring is an important component in the automobile clutch. The diaphragm spring is a type of disc spring. The diaphragm spring is a conical spring sheet made of thin spring steel plate with a certain taper and many radial grooves in the center. In the existing technology, when measuring the inclination angle and flatness of the diaphragm spring cone surface, manual measurement is mostly used. Manual measurement is not only inefficient, but also has large errors. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a diaphragm spring quality detection device to overcome the deficiencies in the above-mentioned prior art.

[0004] The technical solution of the present invention for solving the above-mentioned technical problems is as follows: a diaphragm spring quality detection device comprises a bracket, a horizontal position adjustment mechanism, a first lifting mechanism, a second lifting mechanism, a rotating mechanism, a conveyor line, a bearing platform, a digital micrometer and an industrial control computer, wherein the horizontal position adjustment mechanism is arranged on the bracket, the first lifting mechanism is vertically downwardly arranged on the horizontal position adjustment mechanism, and the digital micrometer is arranged on the first lifting mechanism; the second lifting mechanism is vertically upwardly arranged below the digital micrometer, and the second lifting mechanism is connected to the bracket, the rotating mechanism is arranged on the second lifting mechanism, the bearing platform is arranged on the output shaft of the rotating mechanism, and a conical convex surface matching the concave surface of the diaphragm spring to be tested is provided on the bearing platform, a conveyor line is arranged on each side of the bearing platform, and the spacing between the two conveyor lines is smaller than the diameter of the diaphragm spring to be tested, and the horizontal position adjustment mechanism, the first lifting mechanism, the second lifting mechanism, the rotating mechanism, the conveyor line and the digital micrometer are all electrically connected to the industrial control computer.

[0005] The beneficial effects of the present invention are:

[0006] When in use, the diaphragm spring quality inspection device is connected to the production line, and the carrying platform is lowered below the conveying surfaces of the two conveyor lines. The diaphragm spring to be tested on the production line flows into the two conveyor lines, and then the diaphragm spring to be tested is sent to the top of the carrying platform by the conveyor line and aligned with the carrying platform up and down. The industrial control computer then controls the two conveyor lines to stop, and controls the second lifting mechanism to start, so that the rotating mechanism and the carrying platform rise under the action of the second lifting mechanism until the diaphragm spring to be tested is lifted by the carrying platform. The industrial control computer controls the second lifting mechanism to pause, and controls the horizontal position adjustment mechanism and the first lifting mechanism to start, so that the probe of the digital micrometer moves to contact the conical surface of the diaphragm spring to be tested. Finally, the industrial control computer controls the rotating mechanism to start according to actual needs. The diaphragm spring to be tested will rotate under the action of the rotating mechanism, so that the same diameter of the diaphragm spring can be measured at different positions, so that the flatness of the cone surface can be measured, or the industrial computer can control the horizontal position adjustment mechanism and the first lifting mechanism to adjust the probe of the digital micrometer to contact the cone surface at different heights of the same section of the diaphragm spring to be tested according to actual needs, and then the trigonometric function can be used to measure the inclination angle of the cone surface. After testing one diaphragm spring to be tested, the industrial computer controls the horizontal position adjustment mechanism, the first lifting mechanism, and the second lifting mechanism to return to their positions, and when testing another diaphragm spring to be tested, the above steps can be repeated. No manual participation is required in the entire measurement process, which effectively improves the detection efficiency. In addition, it is conducive to production automation.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, it also includes a sensing device for monitoring whether the diaphragm spring to be tested is aligned up and down with the bearing platform, and the sensing device is electrically connected to the industrial control computer.

[0009] Furthermore, the sensing device includes a light emitter and a light receiver, which are respectively arranged on two conveyor lines. The light receiver is electrically connected to an industrial computer. When the diaphragm spring to be tested is conveyed through the two conveyor lines to be aligned with the supporting platform, the light line emitted from the light emitter to the light receiver is blocked.

[0010] The beneficial effects of adopting the above two steps are: it can effectively ensure that the diaphragm spring to be tested is accurately transported to the specified position, thereby facilitating subsequent testing, and the structure is simple and the stability is good.

[0011] Furthermore, the rotating mechanism includes a driving motor and a reduction box, both of which are fixed on the second lifting mechanism, the output shaft of the driving motor is connected to the input shaft of the reduction box, the output shaft of the reduction box is connected to the supporting platform, and the driving motor is electrically connected to the industrial control computer.

[0012] The above method has the further beneficial effect of effectively driving the diaphragm spring to be tested to rotate, which is convenient for testing, and the addition of a reduction gearbox can reduce the rotation rate of the diaphragm spring to be tested, which is beneficial for subsequent testing.

[0013] Furthermore, the second lifting mechanism includes a support plate and multiple electric push rods, all of which are vertically arranged on the bracket, the support plate is connected to all the electric push rods, the reduction box and the drive motor are respectively arranged on the upper and lower end surfaces of the support plate, and the electric push rods are electrically connected to the industrial control computer.

[0014] A further beneficial effect of the above method is that the supporting platform can be driven to rise and fall effectively and stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, a diaphragm spring quality detection device includes a bracket 1, a horizontal position adjustment mechanism 2, a first lifting mechanism 3, a second lifting mechanism 4, a rotating mechanism 5, a conveyor line 6, a bearing platform 7, a digital micrometer 10 and an industrial computer 8. The horizontal position adjustment mechanism 2 is arranged on the bracket 1, and the first lifting mechanism 3 is connected to the horizontal position adjustment mechanism 2. In this embodiment, the horizontal position adjustment mechanism 2 is preferably a screw slide mechanism, and the first lifting mechanism 3 is preferably an electric push rod. Therefore, the connection between the first lifting mechanism 3 and the horizontal position adjustment mechanism 2 is as follows: the electric push rod is vertically arranged below the screw slide mechanism, and the electric push rod is connected to the slide in the screw slide mechanism, and the digital micrometer 10 is arranged on the first lifting mechanism 3. After the horizontal position adjustment mechanism 2 is working, it will drive the first lifting mechanism 3 to move in the horizontal direction, and after the first lifting mechanism 3 is working, it will drive the digital micrometer 10 to move in the vertical direction.

[0022] The second lifting mechanism 4 is arranged below the digital micrometer 10, and the second lifting mechanism 4 is connected to the bracket 1, the rotating mechanism 5 is arranged on the second lifting mechanism 4, and the bearing platform 7 is arranged on the output shaft of the rotating mechanism 5. The second lifting mechanism 4 is mainly used to drive the rotating mechanism 5 and the bearing platform 7 to rise and fall. The bearing platform 7 is provided with a conical convex surface that matches the concave surface of the diaphragm spring to be tested. A conveyor line 6 is arranged on each side of the bearing platform 7. Figure 1 From the perspective shown, a conveyor line 6 is arranged on each of the left and right sides of the carrying platform 7. The conveying surfaces of the two conveyor lines 6 are flush, and the distance between the two conveyor lines 6 is smaller than the diameter of the diaphragm spring to be tested, so that the diaphragm spring to be tested can be conveyed by the two conveyor lines 6 to be aligned with the carrying platform 7 up and down. The conveyor line 6 is a traditional belt conveyor line or a roller conveyor line. The signal input end of the horizontal position adjustment mechanism 2 is electrically connected to the signal output end of the industrial computer 8, the signal input end of the first lifting mechanism 3 is electrically connected to the signal output end of the industrial computer 8, the signal input end of the second lifting mechanism 4 is electrically connected to the signal output end of the industrial computer 8, the signal input end of the rotating mechanism 5 is electrically connected to the signal output end of the industrial computer 8, the signal input end of the conveyor line 6 is electrically connected to the signal output end of the industrial computer 8, and the signal output end of the digital micrometer 10 is electrically connected to the signal input end of the industrial computer 8.

[0023] The diaphragm spring quality detection device also includes a sensing device 9 for monitoring whether the diaphragm spring to be tested is aligned up and down with the supporting platform 7. The sensing device 9 is electrically connected to the industrial control computer 8. The so-called up and down alignment means that after the supporting platform 7 rises, the conical convex surface and the concave surface of the diaphragm spring to be tested fit perfectly.

[0024] Normally, the sensing device 9 includes a light emitter 910 and a light receiver 920, and the light emitter 910 and the light receiver 920 are respectively arranged on two conveyor lines 6, and the signal output end of the light receiver 920 is electrically connected to the signal input end of the industrial control computer 8. When the diaphragm spring to be tested is transported through the two conveyor lines 6 to be aligned with the supporting platform 7 up and down, the light path emitted from the light emitter 910 to the light receiver 920 is blocked. The light emitter 910 and the light receiver 920 are both commonly used devices on existing production lines.

[0025] The rotating mechanism 5 includes a driving motor 510 and a reduction box 520, both of which are fixed on the second lifting mechanism 4, the output shaft of the driving motor 510 is connected to the input shaft of the reduction box 520, the output shaft of the reduction box 520 is connected to the supporting platform 7, and the driving motor 510 is electrically connected to the industrial control computer 8.

[0026] The second lifting mechanism 4 includes a support plate 410 and multiple electric push rods 420. All the electric push rods 420 are vertically arranged on the bracket 1. The support plate 410 is connected to all the electric push rods 420. The reduction box 520 and the drive motor 510 are respectively arranged on the upper and lower end surfaces of the support plate 410. The electric push rods 420 are electrically connected to the industrial control computer 8.

[0027] In addition, in order to further ensure that the diaphragm spring to be tested can effectively move to align with the upper and lower sides of the carrier 7, a limit plate 11 is installed on each of the two conveyor lines 6, and the distance between the opposite sides of the two limit plates 11 is greater than or equal to the diameter of the diaphragm spring to be tested. If it is greater than, the difference between the two is 0.1mm-5mm. The limit plates 11 are provided with through holes. The setting of the through holes is mainly to not block the light receiver 920 from receiving the light emitted by the light transmitter 910. In addition, the second lifting mechanism 4, the rotating mechanism 5 and the carrier 7 are connected together. When the diaphragm spring to be tested is raised to the detection position, the diaphragm spring to be tested must still be between the two limit plates 11, so that when the diaphragm spring to be tested is tested, the diaphragm spring to be tested is not easy to shake. Furthermore, a limit protrusion can be set on the side of the limit plate 11 close to the diaphragm spring to be tested. When the second lifting mechanism 4, the rotating mechanism 5 and the supporting platform 7 jointly raise the diaphragm spring to be tested to the detection position, the diaphragm spring to be tested can be attached to the lower end surface of the limit protrusion, so that when the diaphragm spring to be tested is tested, the diaphragm spring to be tested is not easy to skew.

[0028] When in use, the diaphragm spring quality detection device is connected to the production line, and the bearing platform 7 is lowered below the conveying surface of the two conveyor lines 6. The diaphragm spring to be tested on the production line flows into the two conveyor lines 6, and then the conveyor lines 6 convey the diaphragm spring to be tested until the sensing device 9 detects the diaphragm spring to be tested. At this time, the diaphragm spring to be tested is located above the bearing platform 7 and is aligned with the bearing platform 7 up and down. The industrial control computer 8 then controls the two conveyor lines 6 to stop, and controls the second lifting mechanism 4 to start, so that the rotating mechanism 5 and the bearing platform 7 rise under the action of the second lifting mechanism 4 until the diaphragm spring to be tested is lifted up by the bearing platform 7. The industrial control computer 8 controls the second lifting mechanism 4 to start. The mechanism 4 is paused, and controls the horizontal position adjustment mechanism 2 and the first lifting mechanism 3 to start, so that the probe of the digital display micrometer 10 moves to contact the conical surface of the diaphragm spring to be tested. Finally, according to actual needs, the industrial control computer 8 controls the rotation mechanism 5 to start, and the diaphragm spring to be tested will rotate under the action of the rotation mechanism 5, so that the diaphragm spring with the same diameter at different positions can be measured, so that the flatness of the conical surface can be measured. When it is necessary to detect the flatness of the conical surface at different diameters, the industrial control computer 8 controls the horizontal position adjustment mechanism 2 and the first lifting mechanism 3 to adjust the probe of the digital display micrometer 10 to contact the conical surface at different diameters of the diaphragm spring to be tested, and then repeat the above test;

[0029] Alternatively, according to actual needs, the industrial computer 8 controls the horizontal position adjustment mechanism 2 and the first lifting mechanism 3 to adjust the probe of the digital micrometer 10 to contact the conical surface at different heights of the same section of the diaphragm spring to be tested, and then the inclination angle of the cone surface can be measured using trigonometric functions. Of course, in order to ensure the accuracy of the detection, the industrial computer 8 can control the rotation mechanism 5 to start, and the diaphragm spring to be tested will rotate a certain angle under the action of the rotation mechanism 5, so that different sections of the diaphragm spring to be tested can be measured, and then the above detection is repeated. After testing one diaphragm spring to be tested, the industrial computer 8 controls the horizontal position adjustment mechanism 2, the first lifting mechanism 3, and the second lifting mechanism 4 to return to their positions, and when testing another diaphragm spring to be tested, the above steps can be repeated.

[0030] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
