Description

Technical Field

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

[0002] Intelligent logistics equipment refers to the mechanical equipment, tools and facilities used for various operations and operations in logistics activities. These equipment include various equipment required for loading and unloading, handling, storage, packaging, sorting, transportation and information processing of goods.

[0003] In the actual production process of intelligent equipment, it is often necessary to produce large disc-type bases for transport robots or other intelligent equipment. In the production process of large disc-type bases, the coaxiality between the inner holes is a key factor in the assembly accuracy of intelligent equipment, affecting the qualification rate of subsequent finished products. However, it is difficult to detect it. At present, the invention patent with publication number CN103417476A discloses a "large disc-type workpiece inner hole coaxiality detection device", which includes a handwheel, an inner cone, an outer cone, a handle, a turntable and a dial indicator; when measuring the inner hole of a large disc-type workpiece, two hands hold the handle to put the detection device into the workpiece as a whole. The workpiece is placed in the reference inner hole of the workpiece, and then the handwheel is rotated to force the inner cone to move axially inward. At the same time, the outer circle of the outer cone is expanded by the action of the inner cone, thereby eliminating the gap between the outer circle of the outer cone and the inner hole Φd of the workpiece, and the large disc-type workpiece is fixed on the workbench; then the dial indicator is placed on the turntable so that the measuring end of the dial indicator contacts the inner hole to be measured, and then the turntable is rotated by hand while observing the changes of the dial indicator, thereby completing the coaxiality detection of the workpiece. However, after a long period of measurement, the worker's vision will become fatigued, which will affect the subsequent measurement accuracy of the inner hole of the large disc-type base, thereby reducing the qualified rate of the subsequent intelligent equipment products to a certain extent.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By sliding the drive shaft on the main shaft and adjusting the height of the detection platform on the workbench at the end of the drive shaft, the distance between the reference inner hole and the inner hole to be measured on different parts can be adapted, 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, the rebound force generated by the compression of the first spring drives the measuring rod to contact the inner hole to be measured, thereby being suitable for measuring inner holes of different inner diameters, reducing the design, manufacturing and storage costs of the detection device.

[0018] The turntable rotates on the workbench, driving several fixed blocks to move radially until the ends of the several fixed blocks respectively contact the reference inner holes. The reaction force generated after the contact restricts the large disc-like components from sliding on the workbench, preventing the large disc-like components from unintentionally moving due to external forces during the measurement process, thereby improving the accuracy of measuring the inner holes of large disc-like components. At the same time, it can be applied to fix reference inner holes of different inner diameters, reducing the design, manufacturing and storage costs of the detection device.

[0019] 2. By rotating the main shaft on the workbench, since the main shaft and the transmission shaft are connected by a spline, the torque generated by the rotation of the main shaft is transmitted to the transmission shaft through the spline, driving the transmission shaft to rotate with the main shaft, so that the measuring rod rotates around the main shaft, and the rebound force generated by the compression of the first spring drives 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 drives 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, the baffle is always within the sensing range of the sensor, blocking part of the infrared rays emitted by the sensor, and transmitting the 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. When the distance between the inner hole to be measured and the theoretical inner hole is within the abnormal value range, the baffle will slide out of the sensing range of the sensor and cannot block the infrared rays emitted by the sensor. The signal is fed back to the control center through the sensor, indicating that the coaxiality of the inner hole to be measured and the reference inner hole does not meet the design requirements, thereby achieving the coaxiality of 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 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 component, and improving the qualified rate of finished products of mass-produced intelligent equipment;

[0020] 3. When it is necessary to fix parts on the workbench, the cooperation among the driving motor, spindle, roller and notch drives the turntable to rotate along with the spindle, and the cooperation among the turntable, arc groove, guide rod, square block and guide groove drives several fixed blocks to move the same distance in the radial direction on the workbench at the same time, so that the reference inner hole of the part and the spindle are at the same center after the workbench, avoiding manual adjustment of the position of the fixed block. Due to manual error, the distance between each fixed block and the spindle changes, resulting in the part and the spindle not being at the same center after being fixed, thereby improving the accuracy of subsequent measurement of the coaxiality of the inner hole to be measured and the reference inner hole;

[0021] After the parts are fixed on the workbench, the cooperation between the fixed block, the reference inner hole, the guide rod and the turntable is used to limit the further rotation of the turntable on the workbench. When the main shaft is further rotated, the cooperation between the roller, the slot, the mounting block, the main shaft and the second spring allows the main shaft to rotate relative to the turntable, and drives the detection platform provided at the end of the transmission shaft to rotate together. The measuring rod contacts the inner hole to be measured to realize the coaxiality detection of the inner hole to be measured and the reference inner hole. At the same time, there is no need to additionally set up 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 main shaft to rotate, and at the same time reduces the cost of 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 slot, the next roller slides into the slot and contacts the slot through the roller. The reaction force generated is continuously applied to the turntable, which offsets the influence of external force on the turntable during the measurement process, and avoids the shaking of the parts during the measurement process affecting the accuracy of measuring the inner hole to be measured and the reference inner hole, thereby improving the accuracy of measuring the coaxiality of the inner hole to be measured and the reference inner hole.

[0022] 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 the tapered block, the main shaft, the first tapered surface, the adjusting block, and the first inclined surface cooperate to drive the several adjusting blocks to slide radially on the main shaft, thereby changing the position of the adjusting block, and the rebound force generated by the compression of the second spring changes the starting position of the roller, thereby changing the compression amount of the second spring required for the roller to slide out of the slot, thereby avoiding the reaction force generated after the roller contacts the slot being too small, failing to drive the turntable to rotate and sliding out of the slot, affecting the normal fixation of the component; at the same time, avoiding the reaction force generated after the roller contacts the slot being too large, aggravating the wear between the fixing block and the workbench, thereby extending the service life of the detection device and improving its detection effect;

[0023] 5. In the initial state, the spline is slidingly set 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, and the coaxiality of the inner hole to be measured and the reference inner hole of the component to be measured is achieved. 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 to be measured and the reference inner hole of the component, and improves the qualified rate of finished products of mass-produced intelligent equipment;

[0024] When the position of the transmission shaft on the main shaft needs to be changed, the spline is driven to slide 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 until one end of the spline slides out of the first spline groove on the main shaft and enters the corresponding third spline groove of the workbench, and 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, the threaded rod on the transmission shaft is threadedly connected with the threaded hole on the main shaft, and the spline limits the rotation of the transmission shaft, so that the transmission shaft slides relative to the main shaft, thereby adjusting the height of the detection platform at the end of the transmission shaft relative to the workbench to adapt to the spacing between the reference inner hole and the inner hole to be measured on different components, thereby reducing the design, manufacturing and storage costs of the detection device; at the same time, there is no need to set up an additional power device on the main shaft to drive the transmission shaft to slide relative to the main shaft, which further reduces the power required to drive the main shaft to rotate, thereby reducing the cost required for the production of the power device and the space required for installation;

[0025] After adjusting the height of the detection platform, the two splines are driven to slide inward at the same time through the cooperation between the telescopic cylinder, the sliding sleeve, the second wedge block, the second cone surface, the first wedge block, and the second inclined surface until the spline slides into the second spline groove again from the third spline groove, and the resistance generated by the contact between the two makes the transmission shaft rotate with the main shaft again, driving the measuring rod to rotate around the main shaft to achieve the coaxiality of 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 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, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0042] The present invention provides a device for detecting inner holes of parts used in the production of intelligent equipment, such as Figure 1 and Figure 7As shown, it includes a workbench 2 for placing a component 1 to be measured, the component 1 is provided with a reference inner hole 3 and an inner hole to be measured, a main shaft 5 is rotatably connected to the workbench 2, and a plurality of fixed blocks 6 are radially slidably connected, the end of the fixed block 6 is in contact with the reference inner hole 3, and the workbench 2 is provided with a turntable 7 for driving the plurality of fixed blocks 6 to move simultaneously. The turntable 7 is rotated on the workbench 2 to drive 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 hole 3. The reaction force generated after the contact limits the large disc-like component 1 from sliding on the workbench 2, and avoids the large disc-like component 1 from being unintentionally moved by external force during the measurement process, thereby improving the accuracy of measuring the inner hole of the large disc-like component 1; at the same time, it is applicable to fixing reference inner holes 3 with different inner diameters, reducing the design, manufacturing and storage costs of the detection device;

[0043] The end of the main shaft 5 is provided with a transmission shaft 8, and the main shaft 5 is provided with a spline 9 that is slidably connected to the transmission shaft 8. The transmission shaft 8 is slid on the main shaft 5, and the height of the detection platform 10 provided at the end of the transmission shaft 8 on the workbench 2 is adjusted to adapt to the spacing 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 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, and a sensor 15 used in conjunction with the baffle 14 is provided on the slider 11. The specific sensor 15 can refer to the AY-44 series photoelectric sensor; 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 after being compressed by the first spring 13 The rebound force generated 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 it is turned within the normal value range, the baffle 14 will slide out of the sensing range of the sensor 15 and will not be able to block the infrared rays emitted by the sensor 15. The signal will be 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, 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, the spline 9 limits the rotation of the transmission shaft 8, so that 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 spacing between the reference inner hole 3 and the inner hole to be measured 4 on different components 1, thereby reducing the design, manufacturing and storage costs of the detection device; at the same time, there is no need to set an additional power device on the main shaft 5 to drive the transmission shaft 8 to slide relative to the main shaft 5, which further reduces the power required to drive the main shaft 5 to rotate, thereby reducing the cost of manufacturing the power device and the space required for installation.

[0048] Preferably, Figure 4As shown, the spline 9 is slidably connected to a push plate 34, and one side of the push plate 34 is provided with a support rod 35 slidably connected to the threaded rod 30, and the outer side of the support rod 35 is provided with a third spring 36, and the third spring 36 is arranged between the push plate 34 and the threaded rod 30. One side of the spline 9 is provided with a first wedge block 37, and the workbench 2 is slidably connected to a sliding sleeve 38, and the sliding sleeve 38 is provided with a second wedge block 39, and one side of the first wedge block 37 is provided with a second inclined surface 40, and one side of the second wedge block 39 is provided with a second conical surface 41 in contact with the second inclined surface 40, and a telescopic cylinder 42 is provided on the workbench 2, and the movable telescopic cylinder 42 The end is connected to the sliding sleeve 38. In the initial state, the spline 9 is in contact with the first spline groove 31 and the second spline groove 32 at the same time. The 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 sliding sleeve 38 is driven to slide upward by the telescopic cylinder 42, so that the first wedge block 37 is no longer in contact with the second wedge block 39. Then, under the action of the rebound force generated by the compression of the third spring 36, the support rod 35 guides the push plate 34 to slide on the threaded rod 30, drives the push plate 34 to slide on the transmission shaft 8, and contacts the spline 9 through the push plate 34, drives the spline 9 to slide on the main shaft 5 until the spline One end of the spline 9 slides out from 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 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 is driven to slide on the main shaft 5, changing the height of the detection platform 10 relative to the workbench 2, adapting to the spacing between the reference inner hole 3 and the inner hole to be measured 4 on different parts 1, and reducing the design, manufacturing and storage costs of the detection device; after the height of the detection platform 10 is adjusted, the sliding sleeve 38 is pushed downward by the telescopic cylinder 42, so that the second wedge block 39 is provided on one side The second conical surface 41 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 at the same time until the spline 9 slides into the second spline groove 32 again through the third spline groove 33. The resistance generated after the contact between the two makes the transmission shaft 8 rotate with the main shaft 5 again, driving the measuring rod 12 to rotate 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 of the component 1 and the reference inner hole 3, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0049] Preferably, Figure 7 and Figure 8As shown, the slider 11 is rotatably connected to a rotating shaft 43, and the rotating shaft 43 is rotatably connected to a first gear 44 and a second gear 45. The slider 11 is slidably connected to a first rack 46 and a second rack 47. 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, and 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 first gear 44 and the second gear 45 have the same module, and the number of teeth of the first gear 44 is smaller than the number of teeth of the second gear 45. When 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 is meshed with the first gear 44, the first gear 44 is driven on the slider 1 1 rotates and transmits torque through the rotating shaft 43, driving the second gear 45 to rotate. Since the second rack 47 is meshed with the second gear 45, the second rack 47 is driven to slide on the slider 11, thereby driving one end of the baffle 14 set at the end of the second rack 47. At the same time, since the first gear 44 and the second gear 45 have the same module and the number of teeth of the first gear 44 is smaller than the number of teeth of the second gear 45, the measuring rod 12 moves a short distance and drives the first gear 44 to rotate a certain angle. After that, the second gear 45 rotates the same angle and drives the second rack 47 to move a greater distance. By adjusting the gear ratio of the first gear 44 and the second gear 45, the moving distance of the measuring rod 12 can be magnified as much as possible, thereby increasing the width of the baffle 14, allowing the sensor 15 to perform better detection, improving the accuracy of the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the detection component 1, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0050] Preferably, Figure 7 、 Figure 8 and Figure 9As shown, the detection platform 10 is provided with a slide groove 48 along the horizontal direction, and the slider 11 is vertically slidably connected to the slide groove 48 with a slide rod 49, one end of the slide rod 49 is provided with a limit block 50, and the slider 11 is provided with a groove 51 slidably connected to the limit block 50, and a plurality of limit grooves 52 connected to the groove 51. The limit block 50 contacts the limit groove 52 and limits the slider 11 from sliding on the detection platform 10. The other end of the slide rod 49 is provided with a protrusion 53, and a fourth spring 5 is provided between the protrusion 53 and the slider 11. 4. When it is necessary to detect the inner holes 4 to be measured with different inner diameters, the slide bar 49 is pressed on the slider 11, so that the limit block 50 provided at the end of the slide bar 49 slides from the limit groove 52 into the groove 51, thereby releasing the restriction on the sliding of the slider 11 on the detection platform 10. Then, the slider 11 is slid on the detection platform 10 until the end of the slider 11 is flush with the corresponding scale line. At the same time, 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, thereby being 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;

[0051] After adjusting the position of the measuring rod 12, the force applied to the slide bar 49 is canceled. Under the action of the rebound force of the fourth spring 54, the slide bar 49 is driven to reset, so that the limit block 50 provided at the end of the slide bar 49 re-enters the limit groove 52, and the resistance generated by the contact between the limit block 50 and the limit groove 52 limits the sliding of the slider 11 on the detection platform 10, avoiding the external force driving the slider 11 to move on the detection platform 10 during subsequent detection, thereby improving the accuracy of the coaxiality of the inner hole 4 to be tested and the reference inner hole 3 of the detection component 1, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0052] Preferably, Figure 7 As shown, the slider 11 is provided with an L-shaped block 56, the sensor 15 is arranged on the vertical side of the L-shaped block 56, and the horizontal side of the L-shaped block 56 is provided with an adjustment slot 57, and also includes a bolt 58. The bolt 58 is threadedly connected to the slider 11 after passing through the adjustment slot 57. By moving the lateral position of the sensor 15 on the slider 11, the zeroing of the detection device is achieved, thereby improving the accuracy of the coaxiality of the inner hole 4 to be tested and the reference inner hole 3 of the subsequent detection of the component 1. After adjusting the position of the L-shaped block 56, the bolt 58 is passed through the adjustment slot 57 until it is threadedly connected to the slider 11, and by further tightening the bolt 58, it contacts the L-shaped block 56 through the nut, and the resistance generated limits the movement of the L-shaped block 56 on the slider 11, thereby avoiding the external force from accidentally changing the position of the L-shaped block 56, and further improving the qualified rate of the component 1 cost.

[0053] Example 1

[0054] The present invention provides a device for detecting inner holes of parts used in the production of intelligent equipment, such as Figure 1 and Figure 7 As 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 main shaft 5 on the workbench 2 passes through the reference inner hole 3. Then, the transmission shaft 8 is slid on the main shaft 5, and the height of the detection platform 10 provided on the end of the transmission shaft 8 on the workbench 2 is adjusted 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, thereby being suitable for measuring inner holes 4 to be measured with different inner diameters, thereby reducing the design, manufacturing and storage costs of the detection device;

[0055] 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 respectively contact the reference inner hole 3. The reaction force generated after the contact restricts the large disc-like component 1 from sliding on the workbench 2, preventing the large disc-like component 1 from unintentionally moving due to external forces during the measurement process, thereby improving the accuracy of measuring the inner hole of the large disc-like component 1. At the same time, it is applicable to fixing reference inner holes 3 of different inner diameters, reducing the design, manufacturing and storage costs of the detection device.

[0056] 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 along 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, transmitting 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, 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 mass-produced intelligent equipment.

[0057] Example 2

[0058] On the basis of Example 1, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, when it is necessary to fix the component 1 on the workbench 2, the main shaft 5 is driven to rotate by the driving motor 55, 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 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 with the turntable 7, and through the sliding contact between the square block 18 and the guide groove 16, it guides the sliding of the fixed block 6 on the workbench 2, thereby driving several fixed blocks 6 to move the same distance radially on the workbench 2 at the same time, so that the component 1 is behind the workbench 2, and its reference inner hole 3 is at the same center of the circle as the main shaft 5, avoiding manual adjustment of the position of the fixed block 6 separately. Due to manual error, the distance between each fixed block 6 and the main shaft 5 changes, resulting in the component 1 being not at the same center of the circle with the main shaft 5 after being fixed, thereby improving the accuracy of subsequent measurement of the coaxiality of the inner hole 4 to be measured and the reference inner hole 3

[0059] 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 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 to the next notch 20. 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 main shaft 5 can rotate relative to the turntable 7, and drive the detection platform 10 provided at the end of the transmission shaft 8 to rotate together, and contact the inner hole 4 to be measured through the measuring rod 12 to achieve the measurement. The coaxiality detection of the inner hole 4 and the reference inner hole 3 is carried out without additionally setting a power device on the main shaft 5 to drive the turntable 7 to rotate relative to the workbench 2, which further reduces the power required to drive the main shaft 5 to rotate, and at the same time reduces the cost of 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 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 the external force on the turntable 7 during the measurement process, avoiding the shaking of the 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;

[0060] In addition, when the inner diameter of the reference inner hole 3 of the component 1 changes, the torque can be applied to the adjusting nut 28 by rotating the wrench, driving the conical block 26 to rotate on the main shaft 5, and the first conical surface 27 provided at the end of the conical block 26 contacts the first inclined surface 25 provided at the end of the adjusting block 24. The component force generated drives several adjusting blocks 24 to slide radially on the main shaft 5 together, thereby changing the position of the adjusting block 24, and the rebound force generated by the compression of the second spring 23 is changed, thereby changing the starting position of the roller 22, thereby changing the compression amount of the second spring 23 required to squeeze the roller 22 out of the slot 20, avoiding the reaction force generated after the roller 22 contacts the slot 20 being too small, failing to drive the turntable 7 to rotate and sliding out of the slot 20, affecting the normal fixation of the component 1; at the same time, avoiding the reaction force generated after the roller 22 contacts the slot 20 being too large, aggravating 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.

[0061] Example 3

[0062] On the basis of Example 1, Figure 1 and Figure 4 As shown, in the initial state, the spline 9 is slidably arranged on the main shaft 5, and the spline 9 is in contact with the first spline groove 31 and the second spline groove 32 at the same time, so that when the driving motor 55 drives the main shaft 5 to rotate, the main shaft 5 drives the transmission shaft 8 to rotate together, so that the measuring rod 12 rotates around the main shaft 5, and the coaxiality of the inner hole 4 to be measured and the reference inner hole 3 of the component 1 is achieved. 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;

[0063] When the position of the transmission shaft 8 on the main shaft 5 needs to be changed, the sliding sleeve 38 is driven to slide upward by the telescopic cylinder 42, so that the first wedge block 37 is no longer in contact with the second wedge block 39. Subsequently, under the action of the rebound force generated by the compression of the third spring 36, the support rod 35 guides the push plate 34 to slide on the threaded rod 30, driving the push plate 34 to slide on the transmission shaft 8, and through the push plate 34, it contacts the spline 9, driving 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 of the workbench 2, while the other end of the spline 9 is always located in the second spline groove 32, thereby changing the position between the transmission shaft 8 and the main shaft 5. The connection relationship is that at this time, when the main shaft 5 is driven to rotate by the driving motor 55, 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 spline 9 is used to limit the rotation of the transmission shaft 8, so that 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, adapting to the distance between the reference inner hole 3 and the inner hole to be measured 4 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 set 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 main shaft 5 to rotate, thereby reducing the cost required for the production of the power device and the space required for installation;

[0064] After the height of the detection platform 10 is adjusted, the sleeve 38 is pushed downward by the telescopic cylinder 42, 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 at the same time until the spline 9 slides into the second spline groove 32 again through the third spline groove 33, and through the resistance generated after the contact between the two, the transmission shaft 8 rotates with the main shaft 5 again, driving the measuring rod 12 to rotate 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, and 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 of the component 1 and the reference inner hole 3, and improving the qualified rate of finished products of mass-produced intelligent equipment.

[0065] Example 4

[0066] On the basis of Example 1, Figure 7-Figure 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, and 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 is engaged with the first gear 44, the first gear 44 is driven to rotate on the slider 11, and the torque is transmitted through the rotating shaft 43, driving the second gear 45 to rotate. Since the second rack 47 is engaged with the second gear 45, the second rack 47 is driven to slide on the slider 11, thereby driving one end of the baffle 14 set at the end of the second rack 47. At the same time, due to the first gear 44 The module of the first gear 44 is the same as that of the second gear 45, and the number of teeth of the first gear 44 is smaller than that of the second gear 45, so that after the measuring rod 12 moves a short 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. By adjusting the gear ratio of the first gear 44 to the second gear 45, the distance moved by the measuring rod 12 can be magnified as much as possible, thereby increasing the width of the baffle 14, allowing 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, and improving the qualified rate of finished products of mass-produced intelligent equipment;

[0067] When it is necessary to detect the inner holes 4 to be measured with different inner diameters, the slide bar 49 is pressed on the slider 11, so that the limit block 50 provided at the end of the slide bar 49 slides from the limit groove 52 into the groove 51, thereby releasing the restriction on the sliding of the slider 11 on the detection platform 10. Then, the slider 11 is slid on the detection platform 10 until the end of the slider 11 is flush with the corresponding scale line. At the same time, 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, thereby being 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;

[0068] After adjusting the position of the measuring rod 12, the force applied to the slide bar 49 is canceled. Under the action of the rebound force of the fourth spring 54, the slide bar 49 is driven to reset, so that the limit block 50 provided at the end of the slide bar 49 re-enters the limit groove 52, and the resistance generated by the contact between the limit block 50 and the limit groove 52 limits the sliding of the slider 11 on the detection platform 10, avoiding the external force driving the slider 11 to move on the detection platform 10 during subsequent detection, thereby improving the accuracy of the coaxiality of the inner hole 4 to be tested and the reference inner hole 3 of the detection component 1, and improving the qualified rate of finished products of mass-produced intelligent equipment.
