Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and specifically to an inner hole detection device for parts used in the production of intelligent equipment. Background Art

[0002] Logistics intelligent equipment refers to mechanical equipment, tools and facilities used for various operations and manipulations in logistics activities. These equipments include various devices required for the links of loading, unloading, handling, storing, packaging, sorting, transporting and information processing of goods.

[0003] In the actual production process of intelligent equipment, it is often necessary to produce large disc-shaped bases for transportation robots or other intelligent equipment. During the production process of large disc-shaped bases, the coaxiality between their inner holes is a key factor affecting the assembly accuracy of intelligent equipment and the qualification rate of subsequent finished products. However, it is difficult to detect. Currently, the invention patent with the publication number of CN103417476A discloses a "coaxiality detection device for inner holes of large disc-shaped workpieces", which includes a handwheel, an inner cone part, an outer cone part, a handle, a rotary table and a dial indicator. When measuring the inner hole of a large disc-shaped workpiece, hold the handle with both hands and put the whole detection device into the reference inner hole of the workpiece. Then rotate the handwheel to force the inner cone part to move axially inward. At the same time, the outer circle of the outer cone part expands through the action of the inner conical surface, so as to eliminate the gap between the outer circle of the outer cone part and the inner hole Φd of the workpiece, and fix the large disc-shaped workpiece on the workbench. Then place the dial indicator on the rotary table so that the measuring end of the dial indicator contacts the inner hole to be measured. Then rotate the rotary table by hand and observe the change of the dial indicator at the same time, so as to complete the detection of the coaxiality of the workpiece. However, after long-term measurement, the vision of workers will become fatigued, which will affect the accuracy of subsequent measurement of the inner holes of large disc-shaped bases, and thus reduce the qualification rate of subsequent intelligent equipment finished products to a certain extent.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By sliding the transmission shaft on the main shaft to adjust the height of the detection platform provided at the end of the transmission shaft on the workbench, so as to adapt to the distance between the reference inner hole and the inner hole to be measured on different parts, reducing the design, manufacturing and storage costs of the detection device; by sliding the slider on the detection platform until the end of the slider is flush with the corresponding scale line, and at the same time, the resilience generated after the first spring is compressed drives the measuring rod to contact the inner hole to be measured, so as to be applicable to the measurement of inner holes to be measured with different inner diameters, reducing the design, manufacturing and storage costs of the detection device; Rotate the turntable on the workbench to drive several fixed blocks to move radially until the end parts of the several fixed blocks are respectively in contact with the reference inner hole. The reaction force generated after contact restricts the sliding of large disc-like parts on the workbench, avoiding the accidental movement of large disc-like parts under external force during the measurement process, thereby improving the accuracy of measuring the inner hole of large disc-like parts. At the same time, it can be applied to the fixation of reference inner holes with different inner diameters, reducing the design, manufacturing, and storage costs of the detection device; 2. By rotating the main shaft on the workbench, since the main shaft and the transmission shaft are connected by splines, the torque generated by the rotation of the main shaft is transmitted to the transmission shaft through the splines, driving the transmission shaft to rotate together with the main shaft, causing the measuring rod to rotate around the main shaft. And through the resilience generated after the compression of the first spring, drive the measuring rod to slide on the slider, so that the end of the measuring rod is always in contact with the inner hole to be measured, and drive the baffle provided at the end of the measuring rod to slide on the slider. When the distance between the inner hole to be measured and the theoretical inner hole is within the normal value range during deflection, the baffle is always within the sensing range of the inductor and blocks part of the infrared rays emitted by the inductor, transmitting a signal to the control center, indicating that the coaxiality of the inner hole to be measured and the reference inner hole meets the design requirements. And when the distance between the inner hole to be measured and the theoretical inner hole is within the abnormal value range during deflection, the baffle will slide out of the sensing range of the inductor and cannot block the infrared rays emitted by the inductor. The signal is fed back to the control center through the inductor, indicating that the coaxiality of the inner hole to be measured and the reference inner hole does not meet the design requirements, thereby realizing the coaxiality of the inner hole to be measured and the reference inner hole of the part. At the same time, there is no need for workers to record or observe for a long time, avoiding visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality of the inner hole to be measured and the reference inner hole of the part, and improving the qualified rate of finished products of mass-produced intelligent equipment; 3. When it is necessary to fix the part on the workbench, through the cooperation between the drive motor, the main shaft, the roller, and the notch, drive the turntable to rotate together with the main shaft, and through the cooperation between the turntable, the arc groove, the guide rod, the square block, and the guide groove, drive several fixed blocks to move the same distance radially on the workbench at the same time, so that after the part is placed on the workbench, its reference inner hole and the main shaft are concentric, avoiding manual adjustment of the position of the fixed block alone. Due to human error, the distance between each fixed block and the main shaft changes, resulting in the part not being concentric with the main shaft after fixation, thereby improving the accuracy of subsequent measurement of the coaxiality of the inner hole to be measured and the reference inner hole; After fixing the components on the workbench, through the cooperation among the fixing block, the reference inner hole, the guide rod and the turntable, the further rotation of the turntable on the workbench is restricted. When the main shaft is further rotated, through the cooperation among the roller, the notch, the mounting block, the main shaft and the second spring, the main shaft can rotate relative to the turntable and drive the detection platform provided at the end of the transmission shaft to rotate together. By making the measuring rod contact with the inner hole to be measured, the coaxiality between the inner hole to be measured and the reference inner hole is detected. At the same time, there is no need to additionally arrange a power device on the main shaft to drive the turntable to rotate relative to the workbench, which further reduces the power required to drive the rotation of the main shaft, and at the same time reduces the cost required for manufacturing the power device and the space required for installation. In addition, by setting the number and spacing of the rollers, when the previous roller slides out of the notch, the next roller slides into the notch, and the reaction force generated by the contact between the roller and the notch is continuously applied to the turntable, offsetting the influence of the external force on the turntable during the measurement process, avoiding the shaking of the components during the measurement process from affecting the accuracy of measuring the inner hole to be measured and the reference inner hole, and thus improving the accuracy of measuring the coaxiality between the inner hole to be measured and the reference inner hole; 4. When the inner diameter of the reference inner hole of the component changes, torque is applied to the adjusting nut by rotating the wrench, and through the cooperation among the tapered block, the main shaft, the first conical surface, the adjusting block and the first inclined surface, a plurality of adjusting blocks are driven to slide radially on the main shaft together, so as to change the position of the adjusting block, and through the resilience generated after the second spring is compressed, the starting position of the roller is changed, so as to change the compression amount of the second spring that needs to be squeezed for the roller to slide out of the notch, avoiding that the reaction force generated after the roller contacts the notch is too small and the roller slides out of the notch before driving the turntable to rotate, affecting the normal fixing of the component; at the same time, avoiding that the reaction force generated after the roller contacts the notch is too large, aggravating the wear between the fixing block and the workbench, and thus prolonging the service life of the detection device and improving its detection effect; 5. In the initial state, the spline is slidably arranged on the main shaft, and the spline is in contact with the first spline groove and the second spline groove at the same time. When the driving motor drives the main shaft to rotate, the main shaft drives the transmission shaft to rotate together, so that the measuring rod rotates around the main shaft, realizing the coaxiality between the inner hole to be measured and the reference inner hole of the component. At the same time, there is no need for workers to record or observe for a long time, avoiding the visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality between the inner hole to be measured and the reference inner hole of the component, and improving the qualified rate of the finished products of mass-produced intelligent equipment; When it is necessary to change the position of the transmission shaft on the main shaft, through the cooperation among the telescopic cylinder, the sliding sleeve, the first wedge block, the second wedge block, the third spring, the support rod, the push plate, the threaded rod and the transmission shaft, the spline is driven to slide on the main shaft until one end of the spline slides out of the first spline groove on the main shaft and enters the corresponding third spline groove on the workbench, while the other end of the spline is always located in the second spline groove, thereby changing the connection relationship between the transmission shaft and the main shaft. At this time, when the main shaft is driven to rotate by the driving motor, since the threaded rod provided on the transmission shaft is in threaded connection with the threaded hole provided on the main shaft, and the spline restricts the rotation of the transmission shaft, the transmission shaft slides relative to the main shaft, so as to adjust the height of the detection platform provided at the end of the transmission shaft relative to the workbench, adapt to the distance between the reference inner hole and the inner hole to be measured on different parts, and reduce the design, manufacturing and storage costs of the detection device; at the same time, there is no need to additionally provide a power device on the main shaft to drive the transmission shaft to slide relative to the main shaft, further reducing the power required to drive the main shaft to rotate, thereby reducing the cost required for manufacturing the power device and the space required for installation; After adjusting the height of the detection platform, through the cooperation among the telescopic cylinder, the sliding sleeve, the second wedge block, the second conical surface, the first wedge block and the second inclined surface, the two splines are driven to slide inward simultaneously until the splines slide back from the third spline groove into the second spline groove, and due to the resistance generated after their contact, the transmission shaft rotates together with the main shaft again, driving the measuring rod to rotate around the main shaft, realizing the coaxiality of the inner hole to be measured and the reference inner hole of the part. At the same time, there is no need for workers to record or observe for a long time, avoiding visual fatigue of workers after long-time measurement, improving the accuracy of detecting the coaxiality of the inner hole to be measured and the reference inner hole of the part, and improving the qualified rate of the finished products of mass-produced intelligent equipment.

Detailed implementation manners

[0026] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0027] The present invention provides a device for detecting the inner hole of parts used in intelligent equipment production, as Figure 1 and Figure 7As shown in the figure, it includes a workbench 2 for placing the component 1 to be measured. The component 1 is provided with a reference inner hole 3 and a measured inner hole 4. A main shaft 5 is rotatably connected to the workbench 2, and several fixing blocks 6 are slidably connected along the radial direction. The end of the fixing block 6 is in contact with the reference inner hole 3. A turntable 7 for driving several fixing blocks 6 to move simultaneously is provided on the workbench 2. By rotating the turntable 7 on the workbench 2, several fixing blocks 6 are driven to move along the radial direction until the end parts of several fixing blocks 6 are respectively in contact with the reference inner hole 3. The reaction force generated after the contact restricts the sliding of the large disc-like component 1 on the workbench 2, avoiding the accidental movement of the large disc-like component 1 under external force during the measurement process, thereby improving the measurement accuracy of the inner hole of the large disc-like component 1; at the same time, it can be applicable to the fixation of reference inner holes 3 with different inner diameters, reducing the design, manufacturing, and storage costs of the detection device; A transmission shaft 8 is provided at the end of the main shaft 5. A spline 9 that is slidably connected to the transmission shaft 8 is provided on the main shaft 5. The transmission shaft 8 is slid on the main shaft 5 to adjust the height of the detection platform 10 provided at the end of the transmission shaft 8 on the workbench 2, so as to adapt to the distance between the reference inner hole 3 and the inner hole 4 to be measured on different parts 1, reducing the design, manufacturing, and storage costs of the detection device. A detection platform 10 is provided at the end of the transmission shaft 8. A slider 11 is slidably connected to the detection platform 10. A measuring rod 12 that contacts the inner hole 4 to be measured is slidably connected to the slider 11. A first spring 13 is provided between the measuring rod 12 and the slider 11. A baffle 14 is provided at the end of the measuring rod 12. An inductor 15 that cooperates with the baffle 14 is provided on the slider 11. Specifically, the inductor 15 can refer to the photoelectric sensor of the AY-44 series; by rotating the main shaft 5 on the workbench 2, since the main shaft 5 and the transmission shaft 8 are connected by the spline 9, the torque generated by the rotation of the main shaft 5 is transmitted to the transmission shaft 8 through the spline 9, driving the transmission shaft 8 to rotate together with the main shaft 5, causing the measuring rod 12 to rotate around the main shaft 5, and through the resilience generated after the compression of the first spring 13, driving the measuring rod 12 to slide on the slider 11, so that the end of the measuring rod 12 always contacts the inner hole 4 to be measured, and driving the baffle 14 provided at the end of the measuring rod 12 to slide on the slider 11. When the distance between the inner hole 4 to be measured and the theoretical inner hole is within the normal value range, the baffle 14 is always within the sensing range of the inductor 15 and blocks part of the infrared rays emitted by the inductor 15, transmitting a signal to the control center, indicating that the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 meets the design requirements. When the distance between the inner hole 4 to be measured and the theoretical inner hole is within the non-normal value range, the baffle 14 will slide out of the sensing range of the inductor 15 and cannot block the infrared rays emitted by the inductor 15. The signal is fed back to the control center through the inductor 15, indicating that the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 does not meet the design requirements, thereby realizing the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the part 1. At the same time, there is no need for workers to record or observe for a long time, avoiding visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the part 1, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0028] Preferably, as Figure 1 、 Figure 2 and Figure 3As shown, a driving motor 55 is provided on the workbench 2, and the movable end of the driving motor 55 is connected to the main shaft 5 to provide power for the rotation of the main shaft 5. A plurality of guiding grooves 16 are provided on the workbench 2 in the radial direction. Further included is a guide rod 17 provided at the end of the fixed block 6. A square block 18 that is slidably connected to the guiding groove 16 is provided in the middle of the guide rod 17. A plurality of arc-shaped grooves 19 that are in contact with the guide rod 17 are provided on the turntable 7. By rotating the turntable 7 on the workbench 2, the arc-shaped grooves 19 provided on the turntable 7 are brought into contact with the guide rod 17. The component forces generated after the contact drive a plurality of guide rods 17 to move following the turntable 7, and through the sliding contact between the square block 18 and the guiding groove 16, it plays a guiding role in the sliding of the fixed block 6 on the workbench 2, thereby driving a plurality of fixed blocks 6 to simultaneously move the same distance in the radial direction on the workbench 2, such that after the component 1 is placed on the workbench 2, its reference inner hole 3 and the main shaft 5 are concentric. This avoids manually adjusting the positions of the fixed blocks 6 individually, which may cause the distances of the respective fixed blocks 6 from the main shaft 5 to change due to manual errors, resulting in the component 1 not being concentric with the main shaft 5 after being fixed, and thus improving the accuracy of measuring the coaxiality of the to-be-measured inner hole 4 and the reference inner hole 3 in the subsequent process.

[0029] Preferably, as Figure 3 , Figure 4 and Figure 5As shown, the turntable 7 is rotatably arranged on the outside of the main shaft 5, and a plurality of notches 20 are arranged on the turntable 7. A mounting block 21 is slidably connected to the main shaft 5, and a roller 22 in contact with the notch 20 is rotatably connected to the mounting block 21. A second spring 23 is arranged between the mounting block 21 and the main shaft 5. When one of the rollers 22 slides out of the notch 20, the next roller 22 slides into the corresponding notch 20. When the main shaft 5 is rotated on the workbench 2, the roller 22 contacts the notch 20, and the two come into contact. The reaction force generated drives the turntable 7 to rotate along with the main shaft 5, and drives several fixed blocks 6 to slide radially on the workbench 2 until the ends of several fixed blocks 6 contact with the reference inner hole 3 at the same time. The resistance generated after the contact will be transmitted to the turntable 7 through the fixed block 6 and the guide rod 17, limiting the turntable 7 from further rotating on the workbench 2. When the main shaft 5 is further rotated, the component force generated after the roller 22 contacts the notch 20 will drive the mounting block 21 to slide on the main shaft 5 and compress the second spring 23 until the roller 22 moves. The spindle 5 moves to the next notch 20, and then the rebound force generated by the compression of the second spring 23 drives the roller 22 to slide out of the notch 20, so that the spindle 5 can rotate relative to the turntable 7, and drives the detection platform 10 provided at the end of the transmission shaft 8 to rotate together, and the measuring rod 12 contacts the inner hole 4 to be measured, so as to realize the coaxiality detection of the inner hole 4 to be measured and the reference inner hole 3. At the same time, there is no need to set an additional power device on the spindle 5 to drive the turntable 7 to rotate relative to the workbench 2, which further reduces the power required to drive the spindle 5 to rotate, and reduces the power The cost required for device manufacturing and the space required for installation. In addition, by setting the number and spacing of rollers 22, when the previous roller 22 slides out of the slot 20, the next roller 22 slides into the slot 20, and the roller 22 contacts the slot 20, and the reaction force generated is continuously applied to the turntable 7, offsetting the influence of external force on the turntable 7 during the measurement process, avoiding the shaking of component 1 during the measurement process to affect the measurement accuracy of the inner hole 4 to be measured and the reference inner hole 3, thereby improving the measurement accuracy of the coaxiality of the inner hole 4 to be measured and the reference inner hole 3.

[0030] Preferably, Figure 5 and Figure 6As shown, a number of adjusting blocks 24 are slidably connected to the main shaft 5. The second spring 23 is arranged between the adjusting block 24 and the mounting block 21. The end of the adjusting block 24 is provided with a first inclined surface 25. A tapered block 26 is threadedly connected to the main shaft 5. The end of the tapered block 26 is provided with a first tapered surface 27 that contacts the first inclined surface 25. One end of the tapered block 26 extends to the outside and is provided with an adjusting nut 28. By rotating the wrench to apply torque to the adjusting nut 28, the tapered block 26 is driven to rotate on the main shaft 5. The first tapered surface 27 provided at the end of the tapered block 26 contacts the first inclined surface 25 provided at the end of the adjusting block 24, and the generated component force drives a number of adjusting blocks 24 to slide radially on the main shaft 5 together, thereby changing the position of the adjusting block 24. And through the resilience generated after the compression of the second spring 23, the starting position of the roller 22 is changed, thereby changing the compression amount of the second spring 23 that needs to be compressed by the roller 22 to slide out from the notch 20, avoiding that the reaction force generated after the roller 22 contacts the notch 20 is too small and the roller 22 slides out from the notch 20 without driving the turntable 7 to rotate, which affects the normal fixing of the component 1; at the same time, avoiding that the reaction force generated after the roller 22 contacts the notch 20 is too large, which aggravates the wear between the fixing block 6 and the workbench 2, thereby extending the service life of the detection device and improving its detection effect.

[0031] Preferably, as Figure 1 and Figure 4As shown, a threaded hole 29 is provided on the main shaft 5, and a threaded rod 30 threadedly connected to the threaded hole 29 is provided on the transmission shaft 8. First spline grooves 31, second spline grooves 32, and third spline grooves 33 that are slidably connected to the spline 9 are respectively provided on the main shaft 5, the transmission shaft 8, and the workbench 2. The spline 9 is slidably arranged on the main shaft 5, and the spline 9 is in contact with both the first spline groove 31 and the second spline groove 32 at the same time. The main shaft 5 drives the transmission shaft 8 to rotate together, so that the measuring rod 12 rotates around the main shaft 5, realizing the coaxiality of the inner hole 4 to be measured of the component 1 and the reference inner hole 3. At the same time, there is no need for workers to record or observe for a long time, avoiding visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1, and improving the qualified rate of finished products of intelligent equipment in mass production; the spline 9 is in contact with both the second spline groove 32 and the third spline groove 33 at the same time, and the generated resistance restricts the rotation of the transmission shaft 8 on the workbench 2, enabling the main shaft 5 to rotate independently relative to the transmission shaft 8. At the same time, since the threaded rod 30 provided on the transmission shaft 8 is threadedly connected to the threaded hole 29 provided on the main shaft 5, and the rotation of the transmission shaft 8 is restricted by the spline 9, the transmission shaft 8 slides relative to the main shaft 5, thereby adjusting the height of the detection platform 10 provided at the end of the transmission shaft 8 relative to the workbench 2 to adapt to the distances between the reference inner hole 3 and the inner hole 4 to be measured on different components 1, reducing the design, manufacturing, and storage costs of the detection device; at the same time, there is no need to additionally provide a power device on the main shaft 5 to drive the transmission shaft 8 to slide relative to the main shaft 5, further reducing the power required to drive the rotation of the main shaft 5, thereby reducing the cost required for manufacturing the power device and the space required for installation.

[0032] Preferably, as Figure 4As shown, a push plate 34 is slidably connected to the spline 9. A support rod 35 slidably connected to the threaded rod 30 is provided on one side of the push plate 34. A third spring 36 is sleeved outside the support rod 35. The third spring 36 is arranged between the push plate 34 and the threaded rod 30. A first wedge block 37 is provided on one side of the spline 9. A sliding sleeve 38 is slidably connected to the workbench 2. A second wedge block 39 is provided on the sliding sleeve 38. A second inclined surface 40 is provided on one side of the first wedge block 37. A second conical surface 41 in contact with the second inclined surface 40 is provided on one side of the second wedge block 39. A telescopic cylinder 42 is provided on the workbench 2. The movable end of the telescopic cylinder 42 is connected to the sliding sleeve 38. In the initial state, the spline 9 is in contact with both the first spline groove 31 and the second spline groove 32 at the same time. The acting force generated after the contact causes the main shaft 5 to drive the transmission shaft 8 to rotate together. When it is necessary to change the position of the transmission shaft 8 on the main shaft 5, the telescopic cylinder 42 is used to drive the sliding sleeve 38 to slide upward, so that the first wedge block 37 is no longer in contact with the second wedge block 39. Subsequently, under the action of the restoring force generated after the compression of the third spring 36, and in cooperation with the guiding of the support rod 35 for the sliding of the push plate 34 on the threaded rod 30, the push plate 34 is driven to slide on the transmission shaft 8, and the push plate 34 is in contact with the spline 9 to drive the spline 9 to slide on the main shaft 5 until one end of the spline 9 slides out of the first spline groove 31 on the main shaft 5 and enters the corresponding third spline groove 33 on the workbench 2, while the other end of the spline 9 is always located in the second spline groove 32, thereby changing the connection relationship between the transmission shaft 8 and the main shaft 5. At this time, when the main shaft 5 is driven to rotate by the driving motor 55, the transmission shaft 8 slides on the main shaft 5, changing the height of the detection platform 10 relative to the workbench 2 to adapt to the distance between the reference inner hole 3 and the to-be-tested inner hole 4 on different parts 1, reducing the design, manufacturing, and storage costs of the detection device; after adjusting the height of the detection platform 10, the telescopic cylinder 42 is used to push the sliding sleeve 38 to slide downward, so that the second conical surface 41 provided on one side of the second wedge block 39 is in contact with the second inclined surface 40 provided on one side of the first wedge block 37. The component force generated after the contact drives the two splines 9 to slide inward at the same time until the spline 9 slides back into the second spline groove 32 from the third spline groove 33 again, and through the resistance generated after their contact, the transmission shaft 8 follows the main shaft 5 to rotate again, driving the measuring rod 12 to rotate around the main shaft 5, realizing the coaxiality of the to-be-tested inner hole 4 and the reference inner hole 3 of the part 1. At the same time, there is no need for workers to record or observe for a long time, avoiding visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality of the to-be-tested inner hole 4 and the reference inner hole 3 of the part 1, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0033] Preferably, as Figure 7 and Figure 8As shown, a rotating shaft 43 is rotatably connected to the slider 11. A first gear 44 and a second gear 45 are rotatably connected to the rotating shaft 43. A first rack 46 and a second rack 47 are slidably connected to the slider 11. The first gear 44 and the second gear 45 are respectively meshed with the first rack 46 and the second rack 47. The measuring rod 12 is arranged on the first rack 46. The first spring 13 is arranged between the first rack 46 and the slider 11. The baffle 14 is arranged at the end of the second rack 47. The module of the first gear 44 and the second gear 45 is the same, and the number of teeth of the first gear 44 is less than that of the second gear 45. When the end of the measuring rod 12 contacts the inner hole 4 to be measured, the generated reaction force drives the measuring rod 12 to slide on the slider 11, and at the same time drives the first rack 46 to slide on the slider 11 together. Since the first rack 46 is meshed with the first gear 44, it drives the first gear 44 to rotate on the slider 11, and transmits torque through the rotating shaft 43 to drive the second gear 45 to rotate. Since the second rack 47 is meshed with the second gear 45, it drives the second rack 47 to slide on the slider 11, thereby driving one end of the baffle 14 arranged at the end of the second rack 47. At the same time, since the module of the first gear 44 and the second gear 45 is the same, and the number of teeth of the first gear 44 is less than that of the second gear 45, after the measuring rod 12 moves a small distance and drives the first gear 44 to rotate a certain angle, the second gear 45 rotates the same angle and drives the second rack 47 to move a greater distance. It is possible to increase the width of the baffle 14 by adjusting the tooth number ratio of the first gear 44 and the second gear 45 as much as possible to magnify the distance moved by the measuring rod 12, so that the inductor 15 can perform better detection, improve the accuracy of detecting the coaxiality of the inner hole 4 to be measured of the component 1 and the reference inner hole 3, and improve the qualified rate of the finished products of the mass-produced intelligent equipment.

[0034] Preferably, as Figure 7 、 Figure 8 and Figure 9As shown, a chute 48 is provided horizontally along the detection platform 10. A slide bar 49 that is slidably connected to the chute 48 is vertically slidably connected to the slider 11. A limiting block 50 is provided at one end of the slide bar 49. A groove 51 that is slidably connected to the limiting block 50 is provided on the slider 11, and a number of limiting grooves 52 that communicate with the groove 51 are provided. The limiting block 50 contacts the limiting grooves 52 and restricts the slider 11 from sliding on the detection platform 10. A convex block 53 is provided at the other end of the slide bar 49. A fourth spring 54 is provided between the convex block 53 and the slider 11. When detecting the inner holes 4 to be measured with different inner diameters, press the slide bar 49 on the slider 11, so that the limiting block 50 provided at the end of the slide bar 49 slides from the limiting groove 52 into the groove 51, releasing the restriction on the slider 11 from sliding on the detection platform 10. Then slide the slider 11 on the detection platform 10 until the end of the slider 11 is flush with the corresponding scale line. At the same time, the resilience generated after the first spring 13 is compressed drives the measuring rod 12 to contact the inner hole 4 to be measured, so as to be applicable to the measurement of the inner holes 4 to be measured with different inner diameters, reducing the design, manufacturing and storage costs of the detection device; After adjusting the position of the measuring rod 12, cancel the force applied to the slide bar 49. Under the action of the resilience of the fourth spring 54, drive the slide bar 49 to reset, so that the limiting block 50 provided at the end of the slide bar 49 re-enters the limiting groove 52, and through the resistance generated after the limiting block 50 contacts the limiting groove 52, restrict the slider 11 from sliding on the detection platform 10, avoiding the slider 11 being driven to move on the detection platform 10 by external forces during subsequent detection processes, thereby improving the accuracy of the coaxiality of the inner hole 4 of the detected part 1 and the reference inner hole 3, and improving the qualified rate of the finished products of mass-produced intelligent equipment.

[0035] Preferably, as Figure 7 shown, an L-shaped block 56 is provided on the slider 11. The inductor 15 is arranged on the vertical side of the L-shaped block 56. An adjustment groove 57 is provided on the horizontal side of the L-shaped block 56. A bolt 58 is also included. The bolt 58 passes through the adjustment groove 57 and is threadedly connected to the slider 11. By moving the horizontal position of the inductor 15 on the slider 11, zero adjustment of the detection device is realized, thereby improving the accuracy of the coaxiality of the inner hole 4 of the detected part 1 and the reference inner hole 3 in subsequent detection. After adjusting the position of the L-shaped block 56, pass the bolt 58 through the adjustment groove 57 until it is threadedly connected to the slider 11, and by further tightening the bolt 58, the nut contacts the L-shaped block 56, and the generated resistance restricts the L-shaped block 56 from moving on the slider 11, avoiding the position of the L-shaped block 56 being inadvertently changed by external forces later, and further improving the qualified rate of the cost of the parts 1.

[0036] Embodiment 1 The present invention provides an inner hole detection device for parts used in the production of intelligent equipment, as Figure 1 and Figure 7As shown, when it is necessary to measure the coaxiality between the reference inner hole 3 and the inner hole 4 to be measured of a large disc-like component 1, the large disc-like component 1 is first placed on the workbench 2, and the spindle 5 on the workbench 2 passes through the reference inner hole 3, then the transmission shaft 8 is slid on the spindle 5, and the height of the detection platform 10 provided at the end of the transmission shaft 8 on the workbench 2 is adjusted, so as to adapt to the spacing between the reference inner hole 3 and the inner hole 4 to be measured on different components 1, thereby reducing the design, manufacturing and storage costs of the detection device; at the same time, the slider 11 is slid on the detection platform 10 until the end of the slider 11 is flush with the corresponding scale line, and the rebound force generated by the compression of the first spring 13 drives the measuring rod 12 to contact the inner hole 4 to be measured, so as to be suitable for measuring the inner holes 4 to be measured with different inner diameters, thereby reducing the design, manufacturing and storage costs of the detection device; Then, the turntable 7 is rotated on the workbench 2, driving the plurality of fixed blocks 6 to move radially until the ends of the plurality of fixed blocks 6 are respectively in contact with the reference inner holes 3. The reaction force generated after the contact restricts the large disk-like component 1 from sliding on the workbench 2, thereby preventing the large disk-like component 1 from being accidentally moved by external force during the measurement process, thereby improving the accuracy of measuring the inner hole of the large disk-like component 1; at the same time, it can be applied to fix the reference inner holes 3 with different inner diameters, reducing the design, manufacturing and storage costs of the detection device; Finally, by rotating the main shaft 5 on the workbench 2, since the main shaft 5 and the transmission shaft 8 are connected by the spline 9, the torque generated by the rotation of the main shaft 5 is transmitted to the transmission shaft 8 through the spline 9, driving the transmission shaft 8 to rotate with the main shaft 5, so that the measuring rod 12 rotates around the main shaft 5, and the rebound force generated by the compression of the first spring 13 drives the measuring rod 12 to slide on the slider 11, so that the end of the measuring rod 12 is always in contact with the inner hole 4 to be measured, and drives the baffle 14 provided at the end of the measuring rod 12 to slide on the slider 11. When the distance between the inner hole 4 to be measured and the theoretical inner hole is within the normal value range, the baffle 14 is always within the sensing range of the sensor 15, and blocks part of the infrared rays emitted by the sensor 15, and the sensor 15 is turned on. A signal is transmitted to the control center, indicating that the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 meets the design requirements. When the distance between the inner hole 4 to be measured and the theoretical inner hole is within the abnormal value range, the baffle 14 will slide out of the sensing range of the sensor 15 and cannot block the infrared rays emitted by the sensor 15. The signal is fed back to the control center through the sensor 15, indicating that the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 does not meet the design requirements, thereby achieving the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1. At the same time, there is no need for workers to record or observe for a long time, which avoids visual fatigue of workers after long-term measurement, improves the accuracy of detecting the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1, and improves the qualified rate of finished products of mass-produced intelligent equipment.

[0037] Example 2 On the basis of Example 1, Figure 2, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , when the component 1 needs to be fixed on the workbench 2, the driving motor 55 drives the main shaft 5 to rotate, driving the roller 22 to contact the notch 20. The reaction force generated after the contact between the two drives the turntable 7 to rotate together with the main shaft 5, so that the arc-shaped groove 19 provided on the turntable 7 contacts the guide rod 17. The component force generated after the contact drives several guide rods 17 to move along with the turntable 7, and through the sliding contact between the square block 18 and the guide groove 16, it plays a guiding role in the sliding of the fixing block 6 on the workbench 2, thereby driving several fixing blocks 6 to move radially on the workbench 2 by the same distance at the same time. After the component 1 is on the workbench 2, its reference inner hole 3 and the main shaft 5 are concentric, avoiding manual adjustment of the position of the fixing block 6 alone, and due to manual error, the distance between each fixing block 6 and the main shaft 5 changes, resulting in the component 1 not being concentric with the main shaft 5 after being fixed, thereby improving the accuracy of measuring the coaxiality of the measured inner hole 4 and the reference inner hole 3 in the subsequent measurement. After the component 1 is fixed on the workbench 2, since the ends of several fixing blocks 6 are in contact with the reference inner hole 3 at the same time, the resistance generated after the contact will be transmitted to the turntable 7 through the fixing blocks 6 and the guide rods 17, restricting the further rotation of the turntable 7 on the workbench 2. When the main shaft 5 is further rotated, the component force generated after the roller 22 contacts the notch 20 will drive the mounting block 21 to slide on the main shaft 5 and compress the second spring 23 until the roller 22 moves to the next notch 20. Then, through the resilience generated after the compression of the second spring 23, the roller 22 is driven to slide out of the notch 20, enabling the main shaft 5 to rotate relative to the turntable 7 and driving the detection platform 10 provided at the end of the transmission shaft 8 to rotate together. By contacting the measured inner hole 4 with the measuring rod 12, the detection of the coaxiality of the measured inner hole 4 and the reference inner hole 3 is realized. At the same time, there is no need to additionally set a power device on the main shaft 5 to drive the turntable 7 to rotate relative to the workbench 2, further reducing the power required to drive the rotation of the main shaft 5, and at the same time reducing the cost required for manufacturing the power device and the space required for installation. In addition, by setting the number and spacing of the rollers 22, when the previous roller 22 slides out of the notch 20, the next roller 22 slides into the notch 20, and through the contact between the roller 22 and the notch 20, the generated reaction force is continuously applied to the turntable 7, offsetting the influence of external forces on the turntable 7 during the measurement process, avoiding the shaking of the component 1 during the measurement process from affecting the accuracy of measuring the measured inner hole 4 and the reference inner hole 3, thereby improving the accuracy of measuring the coaxiality of the measured inner hole 4 and the reference inner hole 3; In addition, when the inner diameter of the reference inner hole 3 of the component 1 changes, torque can be applied to the adjusting nut 28 by turning a wrench, driving the tapered block 26 to rotate on the main shaft 5. The first conical surface 27 provided at the end of the tapered block 26 contacts the first inclined surface 25 provided at the end of the adjusting block 24, and the generated component force drives a plurality of adjusting blocks 24 to slide radially on the main shaft 5 together, thereby changing the position of the adjusting block 24. Through the resilience generated after the compression of the second spring 23, the starting position of the roller 22 is changed, thereby changing the compression amount of the second spring 23 that needs to be compressed for the roller 22 to slide out of the notch 20, avoiding the situation where the reaction force generated after the roller 22 contacts the notch 20 is too small to drive the turntable 7 to rotate and the roller 22 slides out of the notch 20, which affects the normal fixation of the component 1; at the same time, it avoids the situation where the reaction force generated after the roller 22 contacts the notch 20 is too large, which exacerbates the wear between the fixing block 6 and the workbench 2, thereby extending the service life of the detection device and improving its detection effect.

[0038] Embodiment 3 On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, in the initial state, the spline 9 is slidably arranged on the main shaft 5, and the spline 9 contacts both the first spline groove 31 and the second spline groove 32 at the same time. When the driving motor 55 drives the main shaft 5 to rotate, the main shaft 5 drives the transmission shaft 8 to rotate together, causing the measuring rod 12 to rotate around the main shaft 5, realizing the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1. At the same time, there is no need for workers to record or observe for a long time, avoiding visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1, and improving the qualified rate of finished products of intelligent equipment in mass production; When it is necessary to change the position of the transmission shaft 8 on the main shaft 5, the telescopic cylinder 42 drives the sliding sleeve 38 to slide upward, so that the first wedge block 37 no longer contacts the second wedge block 39. Subsequently, under the action of the resilience generated after the third spring 36 is compressed, cooperating with the guiding of the support rod 35 for the sliding of the push plate 34 on the threaded rod 30, the push plate 34 is driven to slide on the transmission shaft 8, and by contacting the spline 9 through the push plate 34, the spline 9 is driven to slide on the main shaft 5 until one end of the spline 9 slides out of the first spline groove 31 on the main shaft 5 and enters the corresponding third spline groove 33 of the workbench 2, while the other end of the spline 9 always remains in the second spline groove 32, thereby changing the connection relationship between the transmission shaft 8 and the main shaft 5. At this time, when the main shaft 5 is driven to rotate by the driving motor 55, since the threaded rod 30 provided on the transmission shaft 8 is threadedly connected with the threaded hole 29 provided on the main shaft 5, and the rotation of the transmission shaft 8 is restricted by the spline 9, the transmission shaft 8 slides relative to the main shaft 5, thereby adjusting the height of the detection platform 10 provided at the end of the transmission shaft 8 relative to the workbench 2 to adapt to the distance between the reference inner hole 3 and the to-be-tested inner hole 4 on different parts 1, reducing the design, manufacturing and storage costs of the detection device; at the same time, there is no need to additionally provide a power device on the main shaft 5 to drive the transmission shaft 8 to slide relative to the main shaft 5, further reducing the power required to drive the rotation of the main shaft 5, thereby reducing the cost required for manufacturing the power device and the space required for installation; After adjusting the height of the detection platform 10, the telescopic cylinder 42 is pushed to drive the sliding sleeve 38 to slide downward, so that the second conical surface 41 provided on one side of the second wedge block 39 contacts the second inclined surface 40 provided on one side of the first wedge block 37. The component force generated after the contact drives the two splines 9 to slide inward simultaneously until the splines 9 slide from the third spline groove 33 back into the second spline groove 32 again, and through the resistance generated after their contact, the transmission shaft 8 rotates together with the main shaft 5 again, driving the measuring rod 12 to rotate around the main shaft 5, realizing the coaxiality of the to-be-tested inner hole 4 and the reference inner hole 3 of the part 1. At the same time, there is no need for workers to record or observe for a long time, avoiding the visual fatigue of workers after long-term measurement, improving the accuracy of detecting the coaxiality of the to-be-tested inner hole 4 and the reference inner hole 3 of the part 1, and improving the qualified rate of the finished products of mass-produced intelligent equipment.

[0039] Example 4 On the basis of Example 1, as Figures 7 - 9As shown, when measuring the coaxiality of the inner hole 4 to be measured and the reference inner hole 3, the end of the measuring rod 12 contacts the inner hole 4 to be measured. The reaction force generated drives the measuring rod 12 to slide on the slider 11, and at the same time drives the first rack 46 to slide on the slider 11. Since the first rack 46 meshes with the first gear 44, it drives the first gear 44 to rotate on the slider 11, and transmits torque through the rotating shaft 43 to drive the second gear 45 to rotate. Since the second rack 47 meshes with the second gear 45, it drives the second rack 47 to slide on the slider 11, thereby driving one end of the baffle 14 provided at the end of the second rack 47. At the same time, since the module of the first gear 44 and the second gear 45 is the same, and the number of teeth of the first gear 44 is less than the number of teeth of the second gear 45, when the measuring rod 12 moves a small distance and drives the first gear 44 to rotate a certain angle, the second gear 45 rotates the same angle and drives the second rack 47 to move a greater distance. It is possible to amplify the distance moved by the measuring rod 12 as much as possible by adjusting the tooth ratio of the first gear 44 and the second gear 45, thereby increasing the width of the baffle 14, enabling the sensor 15 to perform better detection, improving the accuracy of detecting the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1 to be detected, and improving the qualified rate of the finished products of mass-produced intelligent equipment; When it is necessary to detect the inner hole 4 to be measured with different inner diameters, press the sliding rod 49 on the slider 11, so that the limiting block 50 provided at the end of the sliding rod 49 slides from the limiting groove 52 into the groove 51, releasing the restriction on the sliding of the slider 11 on the detection platform 10. Then slide the slider 11 on the detection platform 10 until the end of the slider 11 is flush with the corresponding scale line. At the same time, the resilience generated after the first spring 13 is compressed drives the measuring rod 12 to contact the inner hole 4 to be measured, so as to be applicable to the measurement of the inner hole 4 to be measured with different inner diameters, reducing the design, manufacturing and storage costs of the detection device; After adjusting the position of the measuring rod 12, cancel the force applied to the sliding rod 49. Under the action of the resilience of the fourth spring 54, drive the sliding rod 49 to reset, so that the limiting block 50 provided at the end of the sliding rod 49 re-enters the limiting groove 52, and through the resistance generated by the contact between the limiting block 50 and the limiting groove 52, restrict the sliding of the slider 11 on the detection platform 10, avoiding the movement of the slider 11 on the detection platform 10 driven by external forces during subsequent detection processes, thereby improving the accuracy of detecting the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1 to be detected, and improving the qualified rate of the finished products of mass-produced intelligent equipment.
