[0002] Figures 8 to 10 For a dual-clutch transmission shift hub, after it is processed in an automotive parts factory, the quality inspection process needs to inspect the processing quality of several key running surfaces on it to check whether its processing quality meets the design requirements, otherwise it will affect the smoothness of the shift. Figure 8 and Fig. 9 The three detection surfaces 11 to 13 of each layer of the shift hub 1 and the cylindrical surface 14 at the center of the upper end of the shift hub 1 shown in the figure need to be placed on the tooling 223 to detect whether their contour lines meet the requirements, otherwise it will affect the uneven shifting.

[0003] Currently, a three-coordinate measuring machine is usually used to inspect the four inspection surfaces 11 to 14 respectively, and only one inspection surface can be inspected at a time, which results in low inspection efficiency and increased processing costs. Summary of the invention

[0004] In view of this, the main purpose of the present invention is to provide a shift hub profile line detection device, which is used to detect the detection surfaces of all shift hubs at one time, improve the detection speed, and save processing costs.

[0007] The tightening and rotating mechanism 22 tightens the shift hub 1 on the tooling 223 and drives it to rotate;

[0008] The profile detection mechanism 24 is disposed near the tooling 223 and can be moved close to the shift hub 1 to detect the profile of the detection surface of the shift hub 1 .

[0009] As above, the shift hub is pressed onto the tooling by the clamping and positioning mechanism, and the shift hub is rotated to the zero-point detection position by the tensioning and rotating mechanism 22 to determine the zero-point detection surface position, and the zero-point detection surface position is used as the starting point for detecting the detection surface; then the tensioning and rotating mechanism 22 drives the shift hub to rotate, and the profile detection mechanism 24 detects whether the profile of the detection surface meets the design requirements while the shift hub rotates, and the profile detection of all detection surfaces is completed in one operation, which improves the detection speed and saves processing costs.

[0064] The shift hub profile detection device of the present invention is a special device for detecting the processing quality of the shift hub of a dual clutch transmission, which can detect all surfaces that need to be detected at one time, thereby greatly improving the detection speed.

[0065] like Figure 1 As shown, the shift hub profile detection device 2 includes a clamping and positioning mechanism 21 which is arranged near the tooling 223 and can be moved above the tooling to press the shift hub onto the tooling and position the zero point detection surface 15 on the shift hub 1, a tensioning and rotating mechanism 22 which tightens the shift hub 1 pressed onto the tooling 223 and drives it to rotate, a position detection mechanism 23 which detects whether the position of the shift hub 1 on the tooling 223 is correctly placed, and a profile detection mechanism 24 which detects the profile of the detection surface of the shift hub 1.

[0066] Pressing and positioning mechanism 21

[0067] Figure 2 Shown is a clamping and positioning mechanism 21, which includes a first horizontal moving component 211 arranged near the tooling, and a clamping component 212, a photographing component 213 and a zero-point positioning component 214 arranged on the first horizontal moving component 211. The first horizontal moving component 211 can drive the clamping component 212, the photographing component 213 and the zero-point positioning component 214 to move horizontally to directly above the tooling.

[0068] The clamping assembly 212 includes a clamping top cone 2121 arranged above the tooling 223 and a top cone cylinder 2122 driving the clamping top cone 2121 to move up and down. The extension rod of the top cone cylinder 2122 is extended downward, and the clamping top cone 2121 is installed at the end of the extension rod of the top cone cylinder 2122; when the clamping assembly 212 is driven by the first horizontal moving assembly 211 to move horizontally to the top of the tooling 223, the extension rod of the top cone cylinder 2122 extends downward, and the clamping top cone 2121 moves downward, pressing the top surface of the cylinder 14 in the center of the shift hub placed on the tooling, and pressing the shift hub 1 tightly against the tooling 223.

[0069] After the pressing assembly 212 presses the shift hub 1, the tensioning rotating mechanism 22 described later performs internal tensioning on the shift hub, and after the position detection mechanism 23 detects whether the shift hub is in the correct position, the photographing assembly 213 takes a photo of the shift hub to confirm the relative angle of the zero point detection surface 15 on the shift hub 1 relative to the zero point position of the tooling. A tooling zero point sensor that can sense the zero point mark on the tooling is set near the tooling supporting the shift hub 1. When the tooling is installed, the zero point mark on the tooling corresponds to the tooling zero point sensor. The tooling zero point sensor senses the zero point mark, confirms the tooling zero point position, and transmits the tooling zero point position to the control processing system.

[0070] After the photographing assembly 213 takes a photograph of the shift hub pressed on the tooling 223, the position of the zero point detection surface 15 on the shift hub 1 before it rotates.

[0071] After the photographing assembly 213 takes a photo, the zero point positioning assembly 214 and the later-described tensioning rotating mechanism 22 cooperate to accurately position the position of the zero point detection surface 15 of the shift hub. The zero point positioning assembly 214 is arranged adjacent to the pressing assembly 212 and is arranged side by side. It includes a zero point cylinder 2142 whose extension rod extends downward and a shift hub zero point sensor 2141 arranged at the end of the extension rod of the zero point cylinder 2142. After the top cone cylinder 2122 extends downward to press the top cone 2121 to press the shift hub, the zero point cylinder 2142 extends downward, and the shift hub zero point sensor 2141 moves downward to the zero point detection surface 15 on the shift hub 1. The shift hub 1 is positioned at the same height so that when the shift hub 1 rotates in the horizontal plane to contact the zero point sensor 2141 of the shift hub, the shift hub zero point sensor 2141 can sense the zero point detection surface 15 on the shift hub and transmit the sensed zero point detection surface 15 signal to the control unit, the control unit identifies the relative circumferential angle of the zero point detection surface 15 relative to the zero point of the tooling 223, thereby accurately determining the position of the zero point detection surface of the shift hub, the control unit transmits the identified relative circumferential angle of the zero point detection surface 15 relative to the zero point of the tooling 223 to the rotating component of the tensioning rotating mechanism 22 to drive the shift hub to rotate the circumferential angle.

[0072] Because when accurately determining the position of the zero-point detection surface 15 on the shift hub 1, the shift hub needs to be rotated by a certain angle. Otherwise, if the shift hub rotates by a small angle, the shift hub and the shift hub zero-point sensor 2141 will not be in contact and the zero-point detection surface of the shift hub cannot be sensed. If the shift hub rotates by a large angle, the shift hub 1 will collide with the shift hub zero-point sensor 2141 and damage it. Therefore, the angle at which the shift hub needs to rotate must be determined.

[0073] Tensioning and rotating mechanism 22

[0074] like Figure 3As shown, the tensioning and rotating mechanism 22 includes a tooling 223 for supporting the shift hub, a guide sleeve 221 disposed at the upper end of the tooling 223 , a tensioning assembly 222 for tensioning the shift hub 1 from the inside, and a rotating assembly for driving the shift hub 1 to rotate.

[0075] Eight through holes are arranged at intervals on the outer circumference of the guide sleeve 221. The tensioning assembly 222 includes eight tensioning members 2221 which are respectively arranged in the through holes and can extend out of the through holes, and a tensioning cylinder 2222 which drives the eight tensioning members 2221 to extend out of the through holes. When the extension rod of the tensioning cylinder 2222 is extended upward, the eight tensioning members 2221 are pushed out of the outer circumferential surface of the guide sleeve 221 by a triangular wedge ejection mechanism (not shown in the figure), thereby tightening the shift hub 1 sleeved on the guide sleeve 221.

[0076] The rotating assembly includes a driving motor (not shown in the figure), a main pulley (not shown in the figure) arranged on the output shaft of the driving motor, and a slave pulley 224 coaxially arranged on the upper part of the tensioning cylinder 2222 and the extending rod of the tensioning cylinder 2222. When the driving motor is started, it drives the main pulley to rotate, and the main and slave pulleys are driven by a conveyor belt (not shown in the figure) to transmit power to the slave pulley 224, thereby driving the tooling 223 to rotate, and the shift hub 1 tightened on the tooling 223 also rotates accordingly.

[0077] When the zero point detection surface of the shift hub needs to be accurately determined, the rotating assembly drives the shift hub to rotate the identified circumferential angle according to the driving signal transmitted by the control unit, and then the zero point detection surface 15 contacts the shift hub zero point sensor 2141, thereby accurately positioning the zero point detection surface 15. In addition, when the detection surface of the shift hub needs to be measured, the shift hub 1 also needs to be driven to rotate.

[0078] Position detection mechanism 23

[0079] When the shift hub 1 is placed on the tooling 223, it is sometimes not placed correctly. The pressing assembly 212 presses it, and when the rotating assembly drives it to rotate, because its central axis deviates from its rotation center, the detection accuracy will be reduced when the shift hub is rotated to detect a circle of lines on its detection surfaces 11 to 14. It is necessary to detect whether the shift hub 1 is placed correctly on the tooling 223. When the shift hub 1 is placed on the tooling 223, the horizontal surface 16 inside the shift hub 1 contacts the tooling horizontal surface 2233, and the inner wall surface 17 of the shift hub is adjacent to the step side surface 2231 on the tooling horizontal surface 2233. Figure 4 and Fig. 9 As shown, if the shift hub 1 is placed off-center, the gap between the inner wall surface 17 of the shift hub and the step side surface 2231 on the tooling surface 2233 increases, and the air pressure between the two surfaces during detection is slightly greater than when the shift hub 1 is placed straight.

[0080] A plurality of air outlet holes 2234 are arranged on the step side surface 2231 of the tooling 223 , and an air inlet hole 2232 communicating with all the air outlet holes 2234 is arranged on the other side surface of the tooling 223 below the step side surface 2231 .

[0081] like Figure 5 As shown, the position detection mechanism 23 includes a compression air pipe 232 and a position detection cylinder 231 for driving the compression air pipe 232 to extend toward the air inlet 2232. The compression air pipe 232 is fixedly connected to the extension rod 2311 of the position detection cylinder 231 through a connecting piece. When the extension rod of the position detection cylinder 231 is extended, the compression air pipe 232 is extended to completely press the air inlet 2232 to prevent gas leakage. The other end of the compression air pipe 232 is connected to a gas tank (not shown in the figure). When the air pipe 232 is compressed to press the air inlet hole 2232, the air tank ventilates into the air inlet hole 2232 through the compressed air pipe 232. When the shift hub 1 is not placed properly, the air pressure between the step side 2231 and the inner wall surface 17 of the shift hub is displayed by the pressure gauge 233 arranged on the bracket at the bottom of the position detection cylinder 231. If the value displayed by the pressure gauge 233 is greater than the set value, it means that the shift hub is not placed properly and the clamping assembly 212 needs to be removed. After the shift hub zero point sensor 2141 is moved up, the shift hub 1 is replaced on the tooling 223.

[0082] Profile detection mechanism 24

[0083] After the pressing assembly 212 and the tensioning assembly have respectively pressed and tensioned the shift hub 1, and the zero-point detection surface 15 of the shift hub is determined by the shift hub zero-point sensor 2141 and the shift hub 1 is aligned, the circle of profile lines of the detection surfaces 11 to 13 of each layer of the shift hub 1 are inspected to check whether its processing quality meets the design requirements.

[0084] like Figure 6 It is a schematic diagram of the structure of the detection mechanism 24, which includes a second horizontal moving component 241, a vertical moving component 242 arranged on the second horizontal moving component 241, and an upper detection component 243, a lower detection component 244 and a bottom detection component arranged on the vertical moving component 242.

[0085] The second horizontal moving assembly 241 includes a horizontal cylinder 2411 whose extension rod can extend horizontally toward the detection surfaces 11 to 13 of the shift hub 1 , and a first plate 2412 disposed on the extension rod of the horizontal cylinder 2411 . The vertical moving assembly 242 is disposed on the first plate 2412 .

[0086] The vertical moving assembly 242 includes a vertical cylinder 2421 with an extending rod extending downward, a second plate 2422 arranged at the bottom of the vertical cylinder 2421 to support the vertical cylinder 2421, and a vertical plate arranged on the first plate 2412 and fixedly connected to the second plate 2422. The upper, lower and bottom surface detection assemblies are all arranged on the extending rod of the vertical cylinder 2421.

[0087] The upper and lower detection components are arranged opposite each other on the extension rod of the vertical cylinder 2421, and the upper detection component 243 includes an upper sensor 2431 for detecting the upper surface 11 of each layer of the shift hub 1, and an upper detection cylinder 2432 for driving the upper sensor 2431 to extend horizontally toward the detection surface 11 of the shift hub 1, and the extension directions of the extension rods of the upper detection cylinder 2432 and the horizontal cylinder 2411 are consistent.

[0088] Similarly, the lower detection assembly 244 includes a lower sensor 2441 for measuring the lower surface 13 of each layer of the shift hub 1, and a lower detection cylinder 2442 for driving the lower sensor 2441 to extend horizontally toward the detection surface 13 of the shift hub 1, and the extension rods of the upper and lower detection cylinders extend in the same direction.

[0089] The bottom surface detection assembly includes a line laser detection probe fixedly connected to the upper and lower detection cylinders through an extension rod, and is used to illuminate the bottom surface 12 of each layer of the shift hub 1, so as to measure the profile of the bottom surface 12 of each layer.

[0090] like Figure 2 The clamping and positioning mechanism 21 shown in the figure is also provided with a cylindrical surface detection component for detecting the outer peripheral surface of the cylinder 14 at the center of the upper end of the shift hub 1, such as Figure 7 As shown, the cylindrical detection assembly includes a horizontally arranged cylindrical sensor 246, and the cylindrical sensor 246 and the clamping top cone 2121 are both arranged at the end of the extending rod of the top cone cylinder 2122, and the cylindrical sensor 246 is arranged on one side of the lower part of the clamping top cone 2121, so that after the clamping top cone 2121 compresses the cylinder 14 at the center of the upper end of the shift hub 1, the cylindrical sensor 246 can be close to the outer circumference of the cylinder 14 to detect its one circle profile, thereby detecting whether the profile of the outer circumference of the cylinder is circular.

[0091] The working process of the shift hub profile detection device is described in detail below. First, the shift hub 1 is placed on the guide sleeve 221 of the tooling manually or by a robot. The first horizontal moving component 211 drives the clamping component 212, the camera component 213 and the zero point positioning component 214 to move horizontally above the tooling. The extension rod of the top cone cylinder 2122 of the clamping component 212 extends downward, and moves the clamping top cone 2121 downward to press the upper center cylinder 14 of the shift hub 1, and press the shift hub 1 onto the tooling. 223; the tensioning cylinder 2222 of the tensioning assembly 222 drives the tensioning member 2221 to extend the guide sleeve outward, thereby tightening the shift hub 1 from the inside; the photographing assembly 213 photographs the position of the zero point detection surface on the shift hub 1 and transmits it to the control system, the tooling zero point sensor of the tooling attachment transmits the tooling zero point to the control system, the control system identifies the circumferential angle between the zero point detection surface on the shift hub 1 and the tooling zero point, and the extending rod of the zero point cylinder 2142 of the zero point positioning assembly 214 extends downward to drive the shift hub The zero point sensor 2141 moves downward to the same height as the zero point detection surface. The control system already has the circumferential angle of the shift hub zero point sensor 2141 relative to the tooling zero point. The circumferential angle of the zero point detection surface 15 relative to the shift hub zero point sensor 2141 is calculated based on the two circumferential angles of the zero point detection surface 15 and the shift hub zero point sensor 2141 relative to the tooling zero point. The control system transmits the circumferential angle of the zero point detection surface 15 relative to the shift hub zero point sensor 2141 to the drive motor of the rotating assembly. The drive motor After the shift hub 1 is driven to rotate this angle, the zero point detection surface of the shift hub 1 contacts the shift hub zero point sensor 2141, and the shift hub zero point sensor 2141 senses the zero point detection surface and transmits the signal to the position detection cylinder 231 of the position detection mechanism to extend its extension rod horizontally outward, compress the air pipe 232 to press the air inlet hole 2232 to ventilate inward to detect whether the shift hub 1 is placed correctly, and observe whether the pressure reaches the set value through the pressure gauge 233. If it reaches the set value, the shift hub 1 needs to be repositioned. If the shift hub 1 is placed correctly, the control system reads the value of the pressure gauge and determines that it has not reached the set value, and then controls the second horizontal moving component 241 and the vertical moving component 242 to move horizontally and vertically, and brings the upper detection component 243 and the lower detection component 244 into contact with the upper and lower surfaces of each layer of the shift hub 1, and irradiates the bottom surface of each layer through the line laser probe to detect the contours of the detection surfaces 11 to 13; at the same time, when the top cone cylinder 2122 extends downward, the cylindrical sensor 246 also moves downward together with the pressing top cone 2121, and the pressing top cone 2121 presses the cylinder 14, and the cylindrical sensor 246 is close to the outer circumference of the cylinder 14 to measure the contour of the outer circumference. After all the detection sensors are in place, the control system controls the driving motor of the rotating component to rotate and start measuring the contours of each detection surface.
