Description

Technical Field

[0001] The invention relates to the technical field of automatic detection and roundness correction for gear ring part products, in particular to a roundness correction machine. Background Art

[0002] A roundness calibration machine is a machine that can detect, calculate and calibrate deformed rotating bodies, so that the cylindrical value of the object after calibration is reduced; as a type of rotating body, the processing of gear ring parts needs to first cut the long tube blank into a cylindrical shape of appropriate length, and then put it into a quenching tank for quenching treatment. After quenching, the gear ring parts are subject to thermal stress and structural stress, and the subsequent mechanical stress of the grinding root is superimposed, resulting in elliptical deformation of the thin-walled gear ring. When the elliptical deformation is greater than a certain value, the parts cannot be processed subsequently and must be calibrated;

[0003] At present, there are two conventional methods for gear ring deformation correction. The first method uses an internal expansion ring to physically calibrate the gear ring, which has the disadvantages of poor internal stress elimination effect and complex tooling structure, while the second method uses an external pressure ring to physically calibrate the gear ring, which has the advantages of convenient operation and simple tooling structure. Therefore, the existing external pressure ring method for calibrating the gear ring is the mainstream of existing gear ring parts processing;

[0004] However, in the process of cutting gear ring components from long tube blanks, impurities such as iron filings will be generated. Impurities such as iron filings will adhere to the outer wall of the gear ring, and some residues will remain even after passing through the quenching pool. At the same time, burrs will appear on the cut edges of the cut gear ring. In addition, due to the influence of the environment around the rounding machine, each time the gear ring is rounded, the impurities and burrs attached to the outer wall of the gear ring make the outer wall of the gear ring uneven, which affects the unevenness of the gear ring when placed on the reference support, and at the same time affects the accuracy of the detection device in detecting the outer ring of the gear ring, resulting in inaccurate data collection by the rounding machine, and finally affecting the calibration accuracy of the rounding machine for the gear ring.

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a roundness calibration machine to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 to 6 As shown, a roundness calibration machine according to the present invention comprises:

[0041] Body 1;

[0042] A workbench 2; the workbench 2 is fixedly connected to the lower part of the machine body 1;

[0043] Rotating device 3; the rotating device 3 is arranged at the upper end of the workbench 2, and is used to control the rotation of the workpiece;

[0044] Detection device 4; the detection device 4 is located above the workbench 2 and is used to detect the outer circle data value of the workpiece;

[0045] Calibration device 5; the calibration device 5 is located directly above the workpiece and is used to calibrate the outer circle of the workpiece;

[0046] Industrial computer 6; the industrial computer 6 is fixedly connected to the side wall of the body 1 and is used to control the automatic operation of the present invention;

[0047] The rounding machine also includes:

[0048] Cleaning device 7; the cleaning device 7 is arranged on one side of the rotating device 3, and is used to clean the outer wall of the workpiece before detection;

[0049] During operation, impurities such as iron filings will be generated in the process of cutting gear ring parts from long tube blanks. The iron filings and other impurities will adhere to the outer wall of the gear ring. Even after passing through the quenching tank, some residues will remain. At the same time, the cut edges of the cut gear ring will also appear. In addition, the influence of the surrounding environment of the rounding machine makes the outer wall of the gear ring uneven due to the impurities and burrs attached to the outer wall of the gear ring during each rounding process of the gear ring, which affects the unevenness of the gear ring when placed on the reference support, and further affects the accuracy of the detection device 4 in detecting the outer ring of the gear ring, resulting in inaccurate data collection of the rounding machine, and finally affecting the calibration accuracy of the rounding machine for the gear ring;

[0050] Therefore, the staff of the present invention places the gear ring on the rotating device 3, the cleaning device 7 contacts the outer wall of the gear ring, controls the rotating device 3 to rotate through the industrial computer 6, and the rotation of the rotating device 3 drives the gear ring to rotate, so that the gear ring and the cleaning device 7 form a relative device, so that the cleaning device 7 scrapes the outer wall of the gear ring, so that the burrs on the outer wall of the gear ring and the protruding outer wall of the gear ring edge are scraped off by the cleaning device 7, so that the outer wall of the gear ring is cleaned, ensuring the smoothness of the outer wall of the gear ring, so that impurities will not be stuck between the gear ring and the rotating device 3, causing the gear ring to be placed unevenly and affecting the detection device 4 The detection accuracy is then determined by the industrial computer 6, which drives the detection device 4 to move closer to the gear ring, and finally detects the highest point on the gear ring, and stores the value in the industrial computer 6. The rotating device 3 then drives the gear ring to rotate, detects the value of one circle of the outer edge of the gear ring, and measures and stores the detection value of each point. The industrial computer 6 then controls the calibration device 5 to press down and automatically calibrate the circle, and so on until the entire circle of the gear ring meets the qualified standard, that is, the gear ring calibration is completed. At this time, since the outer wall of the gear ring is cleaned by the cleaning device 7, impurities will not be stuck between the gear ring and the detection device 4, causing the detection accuracy to be affected.

[0051] The present invention uses the cleaning device 7 to clean the outer surface of the workpiece before the workpiece is detected, thereby reducing the influence of impurities on the outer surface of the workpiece on the detection result, thereby improving the accuracy of the workpiece roundness correction.

[0052] As an embodiment of the present invention, the roundness calibration machine further includes a support head 8 and a second hydraulic cylinder 81; the second hydraulic cylinder 81 is fixedly connected to the center of the workbench 2; the upper end of the second hydraulic cylinder 81 is fixedly connected to the support head 8;

[0053] The rotating device 3 includes a support block 31, a roller 32 and a No. 1 motor 33; the support blocks 31 are located on both sides of the support head 8 and are fixedly connected to the upper end of the workbench 2, and a roller 32 is rotatably connected between every two support blocks 31; the central axes of the two rollers 32 are parallel, and one end of one of the rollers 32 is fixedly connected to the output shaft of the No. 1 motor 33; the No. 1 motor 33 is fixedly connected to the upper end of the workbench 2;

[0054] The detection device 4 includes a screw 41, a slide bar 42, a detection plate 43, an upper plate 44 and a second motor 45; the upper part of the body 1 is fixedly connected to the upper plate 44; the screw 41 is rotatably connected between the upper plate 44 and the workbench 2, and the slide bar 42 is fixedly connected between the upper plate 44 and the workbench 2; a detection plate 43 is provided between the upper plate 44 and the workbench 2; the detection plate 43 is slidably connected to the slide bar 42, and the detection plate 43 is threadedly connected to the screw 41; the upper end of the upper plate 44 is fixedly connected to the second motor 45; the second motor 45 is fixedly connected to one end of the screw 41;

[0055] The calibration device 5 includes a No. 1 hydraulic cylinder 51 and a pressure head 52; the No. 1 hydraulic cylinder 51 is fixedly connected to the upper part of the machine body 1; the No. 1 hydraulic cylinder 51 is located directly above the support head 8; the output shaft of the No. 1 hydraulic cylinder 51 is fixedly connected to the pressure head 52;

[0056] The cleaning device 7 comprises a cleaning plate 71; a surface of the cleaning plate 71 close to the workpiece is knurled;

[0057] During operation, after the gear ring is placed between the two rollers 32 and contacts with the rollers 32, the No. 1 motor 33 drives the rollers 32 to rotate, and the rotation of the rollers 32 drives the gear ring to rotate. The rotated gear ring and the cleaning plate 71 produce relative displacement, and the knurled side of the cleaning plate 71 increases the friction between the cleaning plate 71 and the outer surface of the gear ring, thereby improving the cleaning effect of the cleaning plate 71. After the outer surface of the gear ring is cleaned, the industrial computer 6 controls the No. 2 motor 45 to rotate, and the rotating No. 2 motor 45 drives the screw 41 to rotate, so that the detection plate 43 slides along the slide rod 42 driven by the screw 41, and finally contacts with the highest point above the gear ring. The industrial computer 6 records this point, and then the No. 1 motor 33 drives the corresponding roller 32 to continue to rotate, so that the industrial computer 6 captures one circle value of the gear ring, and finally After analysis, the No. 1 hydraulic cylinder 51 drives the pressure head 52 to extrude the gear ring through the detection plate 43, so that the gear ring is calibrated. In the process of the No. 1 hydraulic cylinder 51 driving the pressure head 52 to extrude the gear ring, the No. 2 hydraulic cylinder 81 drives the support head 8 to hold the lowest point below the gear ring to provide support for the gear ring, thereby reducing the deformation of the roller 32 caused by the pressure of the gear ring being transmitted to the roller 32, thereby greatly improving the service life of the present invention. For gear rings of different specifications, the No. 2 hydraulic cylinder 81 rises to different heights, so that the present invention can be applied to different specifications. In the process of the gear ring being cleaned by the cleaning plate 71, the No. 2 hydraulic cylinder 81 drives the support head 8 away from the gear ring to prevent the support head 8 from contacting with the gear ring and scraping off impurities on the outer edge of the gear ring and falling to the upper end of the support head 8, thereby affecting the support effect of the support head 8 on the gear ring.

[0058] As an embodiment of the present invention, the cleaning device 7 also includes a slide cylinder 72, a slide plate 73, a sliding rod 74 and a spring 75; the slide cylinder 72 is fixedly connected to the top of the workbench 2; the slide cylinder 72 is located below the two ends of the cleaning plate 71; the inner wall of the slide cylinder 72 is slidably connected to the slide plate 73; the lower end of the slide plate 73 is fixedly connected to the spring 75; the upper end of the slide plate 73 is fixedly connected to the sliding rod 74; the sliding rod 74 extends to the outside of the slide cylinder 72; the cleaning plate 71 is rotatably connected between the two sliding rods 74; during operation, when the gear ring is placed in the rotating device 3, due to the action of the spring 75, the spring 75 squeezes the slide plate 73 to the upper limit position inside the slide cylinder 72, so that the slide plate 73 drives the sliding rod 74 to a certain upper limit position, and the sliding rod 74 drives the cleaning plate 71 to move to the upper limit position, and the elastic force of the spring 75 is greater than the gravity of the gear ring, so when the cleaning plate 71 is away from the cleaning plate 7 1, the gear ring is tilted and stuck between the roller 32 far away from the cleaning plate 71 and the cleaning plate 71, and then the No. 1 motor 33 drives the roller 32 to rotate, so that the roller 32 drives the gear ring to rotate. This suspended and tilted manner prevents the gear ring with impurities from contacting the other roller 32 and the support head 8, reducing the adhesion of impurities to the other roller 32 and the support head 8, and reducing the impact of impurities adhesion on the roller 32 and the support head 8 during the detection process. The detection accuracy is affected by the adhesion of impurities between the roller 32 and the support head 8. This embodiment can also clean the roller 32 during the rolling process by arranging a scraper between the bottom of the roller 32 and the workbench 2. After the gear ring is cleaned, the No. 2 motor 45 drives the detection plate 43 to press the gear ring, so that the gear ring overcomes the elastic force of the spring 75 and is stuck between the two rollers 32, and then the detection device 4 cooperates with the rotating device 3 to realize the detection. In this way, the cleaning device 7 can clean gear rings of different specifications, and its application range is wider.

[0059] As an embodiment of the present invention, both ends of the cleaning plate 71 are fixedly connected to extension rods 76; the two extension rods 76 are fixedly connected to one side of the collecting membrane 77; a collecting box 11 is provided at the lower part of the body 1; a through-hole 21 is provided at the upper end of the workbench 2; the through-hole 21 is connected to the collecting box 11, and the upper end of the through-hole 21 is connected to the other side of the collecting membrane 77; during operation, in the process of scraping and cleaning the gear ring by the cleaning plate 71, impurities on the gear ring will fall on the collecting membrane 77, and finally extend along the collecting membrane 77 along the through-hole 21 to the collecting box 11 for collection. In the process of scraping impurities by the cleaning plate 71, such as burrs, vibration will occur, and the vibration will drive the extension rod 76 to vibrate, and the vibration of the extension rod 76 will drive the collecting membrane 77 to vibrate, and the impurities on the collecting membrane 77 will fall into the collecting box 11 along the through-hole 21 under the action of the vibration.

[0060] As an embodiment of the present invention, the extension rod 76 extends away from the cleaning plate 71; an iron chain 78 is fixedly connected to one side of the collecting film 77; the iron chain 78 is fixedly connected between the two extension rods 76; during operation, the collecting film 77 will be squeezed when the gear ring is placed on the cleaning plate 71 and the roller 32, and the collecting film 77 will be deformed to make linear contact with the outer surface of the gear ring, and also contact with the side end surface of the gear ring. During the rotation of the gear ring after being driven, the iron chain 78 on the collecting film 77 can protect the collecting film 77 on the one hand, and can grind the outer surface and side end surface of the gear ring on the other hand, thereby saving the subsequent workpiece deburring processing steps.

[0061] As an embodiment of the present invention, one end of the extension rod 76 that is fixedly connected to the cleaning plate 71 is fixedly connected to a baffle rod 79; the baffle rod 79 can contact the sliding rod 74 after the cleaning plate 71 rotates; during operation, after the gear ring is calibrated and removed, the spring 75 will drive the slide plate 73 to slide upward along the inner wall of the slide tube 72, and the slide plate 73 will drive the sliding rod 74 to slide upward during the sliding process, and the sliding rod 74 will drive the cleaning plate 71 to move upward, and the cleaning plate 71 will rotate under the pull of the collecting film 77. After the cleaning plate 71 rotates, the baffle rod 79 restricts the rotation of the cleaning plate 71, and finally the baffle rod 79 contacts the sliding rod 74. In this state, the cleaning plate 71 can be kept in an inclined state, which is convenient for the new gear ring to be placed again, otherwise the cleaning plate 71 will deviate from the new gear ring under the pull of the collecting film 77.

[0062] As an embodiment of the present invention, a chip groove 711 is provided through the end surface of the cleaning plate 71 close to the workpiece; the chip groove 711 is arranged at an angle; during operation, impurities generated in the process of the cleaning plate 71 scraping the outer wall of the gear ring are discharged through the chip groove 711 and finally fall on the collection film 77, thereby preventing the cleaning effect of the cleaning plate 71 from being affected due to the impurities on the cleaning plate 71 not being discharged in time.

[0063] As an embodiment of the present invention, the portion where the blocking rod 79 and the sliding rod 74 are close to each other is made of a magnetic material, such as a magnet; the magnetism on the blocking rod 79 and the sliding rod 74 is oppositely arranged; the collecting film 77 is made of an elastic material, such as rubber; during operation, after the gear ring is removed from the rotating device 3, the cleaning plate 71 moves upward under the action of the spring 75, so that the cleaning plate 71 pulls the collecting film 77, so that the cleaning plate 71 rotates under the pull of the collecting film 77, and the rotating cleaning plate 71 drives the blocking rod 79 to approach the sliding rod 74, but because the blocking rod 79 and the sliding rod The opposite magnetic settings on 74 make the two repel each other, and the repelling baffle 79 drives the cleaning plate 71 to rotate, so that the cleaning plate 71 pulls the collecting film 77 again, and at the same time the spring 75 is deformed again, causing the cleaning plate 71 and the collecting film 77 to vibrate and shake, so that the impurities on the collecting film 77 fall into the through-port 21 under the action of vibration, and the impurities on the cleaning plate 71 fall off under the action of vibration, thereby ensuring the cleanliness of the cleaning plate 71, thereby maintaining the cleaning effect. The better the cleaning effect of the outer surface of the gear ring, the higher the detection accuracy of the detection device 4, that is, the higher the calibration accuracy of the circularity machine.

[0064] The specific workflow is as follows:

[0065] The staff places the gear ring on the rotating device 3, and the cleaning device 7 contacts the outer wall of the gear ring. The industrial computer 6 controls the rotation of the rotating device 3, and the rotation of the rotating device 3 drives the gear ring to rotate, so that the gear ring and the cleaning device 7 form a relative device, so that the cleaning device 7 scrapes the outer wall of the gear ring, so that the burrs on the outer wall of the gear ring and the protruding outer wall of the gear ring edge are scraped off by the cleaning device 7, so that the outer wall of the gear ring is cleaned, ensuring the smoothness of the outer wall of the gear ring, so that impurities will not be stuck between the gear ring and the rotating device 3, causing the gear ring to be placed unevenly and affect the detection accuracy of the detection device 4, then the industrial computer 6 drives the detection device 4 to move close to the gear ring, and finally detects the highest point above the gear ring, and saves the value in the industrial computer 6, then the rotating device 3 drives the gear ring to rotate, detects the value of one circle of the outer edge of the gear ring, and measures and saves the detection value of each point, and then the industrial computer 6 controls the calibration device 5 to press down for automatic rounding, and so on until one circle of the gear ring meets the qualified standard, that is, the gear ring rounding is completed;

[0066] Among them, after the gear ring is placed between the two rollers 32 and contacts with the rollers 32, the No. 1 motor 33 drives the rollers 32 to rotate, and the rotation of the rollers 32 drives the gear ring to rotate. The rotated gear ring and the cleaning plate 71 produce relative displacement, and the knurled side of the cleaning plate 71 increases the friction between the cleaning plate 71 and the outer surface of the gear ring, thereby improving the cleaning effect of the cleaning plate 71. After the outer surface of the gear ring is cleaned, the industrial computer 6 controls the No. 2 motor 45 to rotate, and the rotating No. 2 motor 45 drives the screw 41 to rotate, so that the detection plate 43 slides along the slide rod 42 driven by the screw 41, and finally contacts with the highest point above the gear ring. The industrial computer 6 records this point, and then the No. 1 motor 33 drives the corresponding roller 32 to continue rotating, so that the industrial computer 6 can check one circle of the gear ring. It is worth capturing, and finally after analysis, the pressure head 52 is driven by the No. 1 hydraulic cylinder 51 to squeeze the gear ring through the detection plate 43, so that the gear ring completes the rounding. In the process of the No. 1 hydraulic cylinder 51 driving the pressure head 52 to squeeze the gear ring, the No. 2 hydraulic cylinder 81 drives the support head 8 to hold the lowest point below the gear ring to provide support for the gear ring, reduce the deformation of the roller 32 caused by the pressure of the gear ring being transmitted to the roller 32, and greatly improve the service life of the present invention. The No. 2 hydraulic cylinder 81 rises to different heights for gear rings of different specifications, so that the present invention can be applied to different specifications. In the process of the gear ring being cleaned by the cleaning plate 71, the No. 2 hydraulic cylinder 81 drives the support head 8 away from the gear ring to prevent the support head 8 from scraping off the impurities on the outer edge of the gear ring due to contact with the gear ring and falling to the upper end of the support head 8;

[0067] When the gear ring is placed in the rotating device 3, due to the action of spring 75, the spring 75 squeezes the slide plate 73 to the upper limit position inside the slide cylinder 72, so that the slide plate 73 drives the sliding rod 74 to the upper limit position, and the sliding rod 74 drives the cleaning plate 71 to move to the upper limit position. The elastic force of spring 75 is greater than the gravity of the gear ring. Therefore, under the support of the cleaning plate 71 and the roller 32 away from the cleaning plate 71, the gear ring is tilted and stuck between the roller 32 away from the cleaning plate 71 and the cleaning plate 71. Then the No. 1 motor 33 drives the roller 32 to rotate, so that the roller 32 drives the gear ring to rotate. This suspended and tilted method makes it possible to remove impurities The gear ring does not contact the other roller 32 and the support head 8, reducing the adhesion of impurities to the other roller 32 and the support head 8, and reducing the impact of impurities adhesion on the detection accuracy during the detection process. The present embodiment can also clean the roller 32 during the rolling process by setting a scraper between the bottom of the roller 32 and the workbench 2. After the gear ring is cleaned, the second motor 45 drives the detection plate 43 to press the gear ring, so that the gear ring overcomes the elastic force of the spring 75 and is stuck between the two rollers 32, and then the detection is realized by the detection device 4 and the rotating device 3. In this way, the cleaning device 7 can clean gear rings of different specifications.

[0068] In the process of cleaning the gear ring by scraping the cleaning plate 71, the impurities on the gear ring will fall on the collecting film 77, and finally extend along the collecting film 77 along the through-hole 21 to the collecting box 11 for collection. In the process of cleaning the impurities by scraping the cleaning plate 71, such as burrs, vibration will occur, which will drive the extension rod 76 to vibrate, and the vibration of the extension rod 76 will drive the collecting film 77 to vibrate. Under the action of the vibration, the impurities on the collecting film 77 will fall into the collecting box 11 along the through-hole 21; when the gear ring is placed on the cleaning plate 71 and the roller 32, the collecting film 77 will be squeezed, and the collecting film 77 will be deformed. The outer surface of the gear ring will be in line contact with the gear ring, and it will also be in contact with the side end surface of the gear ring. When the gear ring is driven to rotate, the iron chain 78 on the collection film 77 can protect the collection film 77 on the one hand, and can grind the outer surface and side end surface of the gear ring on the other hand, thereby saving the subsequent workpiece deburring processing steps; after the gear ring is calibrated and removed, the spring 75 will drive the slide plate 73 to slide upward along the inner wall of the slide cylinder 72. During the sliding process of the slide plate 73, it drives the sliding rod 74 to slide upward, and the sliding rod 74 drives the cleaning plate 71 to move upward. The cleaning plate 71 will be pulled by the collection film 77. The cam 77 is pressed against the locking cam 74 so that the locking cam 73 is in contact with the locking cam 74. When the cam 77 is in contact with the locking cam 74, the locking cam 73 is in contact with the locking cam 74. When the cam 77 is in contact with the locking cam 74, the locking cam 73 is in contact with the locking cam 74. The membrane 77 causes the cleaning plate 71 to rotate under the pull of the collecting membrane 77, and the rotating cleaning plate 71 drives the blocking rod 79 to approach the sliding rod 74. However, since the magnetic properties on the blocking rod 79 and the sliding rod 74 are set in opposite directions, the two repel each other, and the repelling blocking rod 79 drives the cleaning plate 71 to rotate, so that the cleaning plate 71 pulls the collecting membrane 77 again, and at the same time the spring 75 is deformed again, causing the cleaning plate 71 and the collecting membrane 77 to vibrate and shake, so that the impurities on the collecting membrane 77 fall into the through-hole 21 under the action of the vibration, and the impurities on the cleaning plate 71 fall off under the action of the vibration.
