Description

Technical Field

[0001] This invention relates to the technical field of testing equipment, and in particular to a device for testing the quality of I-beam wheels. Background Technology

[0002] H-beam reels are a general-purpose tooling container used for winding metal wires, optical fibers, cables, and textile fibers. They are widely used in manufacturing and logistics processes. H-beam reels generally have a center hole and a drive hole. The center hole is used to position the rotation axis of the H-beam reel, while the drive hole is mainly used to transmit rotational torque to the H-beam reel. The geometric accuracy of the center hole and drive hole on the H-beam reel directly affects the stability of subsequent automatic winding, tension control, and reel changing operations.

[0003] Currently, the inspection of the center hole and drive hole on the I-beam wheel generally relies on manual operation or simple measuring tools. Common methods include using plug gauges and vernier calipers to measure the hole diameter, or using scribing rulers and angle templates to compare and measure the position of the drive hole. These inspection methods are prone to affecting the measurement accuracy due to the subjective error of workers. At the same time, the inspection of a single piece is time-consuming and difficult to meet the requirements of large-scale production. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a quality inspection device for I-beam wheels, the specific technical solution of which is as follows: The present invention provides a quality inspection device for I-beam wheels, comprising a power ring capable of rotating and a clamping structure for fixing the I-beam wheel. The clamping structure makes the axis of the central hole of the I-beam wheel coincide with the axis of the power ring. A rangefinder and a support body are provided on the power ring. The rangefinder is used to detect the distance between itself and the outer circumference of the side plate of the I-beam wheel. A movable sleeve that slides along the radial direction of the power ring and a distance sensor for detecting the position of the movable sleeve on the support body are provided on the support body. A pushing structure is provided at the bottom of the movable sleeve, and a top pressing body is provided at the bottom of the pushing structure. The top pressure body is used to detect the position of the drive hole on the side plate of the I-beam wheel, and the shape of the top pressure body is either conical or spherical.

[0005] Furthermore, a column is provided on the side wall of the power ring, a cross arm is provided on the top of the column, a support frame is provided on one side wall of the column, the support is provided on the cross arm, and the rangefinder is provided on the support frame. The rangefinder is set to one or two. When there is one rangefinder, the support frame slides vertically on the column, so that the rangefinder can detect either of the two side plates on the I-beam wheel. When there are two rangefinders, the two rangefinders detect the two side plates on the I-beam wheel respectively.

[0006] Furthermore, the propulsion structure includes a support sleeve and a movable column that are nested together and can slide relative to each other. The support sleeve and the movable column are respectively disposed on the movable sleeve and the top pressure body. A coil is disposed on the inner wall of the support sleeve, and a magnet is disposed on the inner side of the coil. The magnet is connected to the movable column.

[0007] Furthermore, a ramp and a slider are provided between the movable sleeve and the support sleeve. The ramp is connected to the movable sleeve, and the slider is connected to the support sleeve. The slider slides on the ramp, and the sliding direction of the slider is perpendicular to the radial movement trajectory of the movable sleeve. The ramp and the slider are connected by a spring, and both the ramp and the slider are equipped with electromagnetic suction plates that work together.

[0008] Furthermore, the movable sleeve is provided with a reset structure for providing a reset force to the movable sleeve. The reset structure includes a second coil, a magnetic post located inside the second coil, a connecting plate disposed on the outer wall of the magnetic post, and two conductive plates disposed on each side wall of the connecting plate. The second coil is composed of several coaxially arranged arc-shaped wires. The second coil is fixedly disposed relative to the support body. The magnetic post is fixedly disposed relative to the movable sleeve through the connecting plate. The polarity of the two conductive plates on one side of the connecting plate is opposite to the polarity of the two conductive plates on the other side. The two conductive plates on each side of the connecting plate are electrically connected to the two ends of the arc-shaped wires and can be slidably disposed relative to each other.

[0009] Furthermore, the reset structure also includes an isolation cylinder one, which is fixedly connected to the support body. The coil two is fixed to the inner wall of the isolation cylinder one. An opening is provided at the bottom of the isolation cylinder one. An isolation cylinder two is slidably sleeved on the outer wall of the isolation cylinder one. The connecting plate passes through the opening and is fixedly connected to the isolation cylinder two. The isolation cylinder two is fixedly connected to the movable sleeve.

[0010] Furthermore, the clamping structure includes a fixed post and a spindle rotatably located inside the fixed post. Two support groups are arranged opposite each other on the outer wall of the fixed post. Each support group includes a transmission wheel rotatably mounted on the fixed post and a support arm mounted on the outer wall of the transmission wheel. Part of the transmission wheel is located inside the fixed post. Two drive wheels are arranged on the outer wall of the spindle, and the drive wheels are connected to the corresponding transmission wheels in a transmission connection. The transmission wheel and the support arm are both inclined, and the inclination directions of the support arms in the two support groups are opposite. The support arm is arc-shaped, and the outer end of the support arm is set as a right angle, which is used in conjunction with the inner angle of the center hole of the I-beam wheel.

[0011] Furthermore, the power ring is provided with a slide block that slides along the trajectory of the power ring, and the slide block is provided with a second column that is parallel to the first column. The second column is provided with a second cross arm, the end of the second cross arm is rotatably connected to the end of the first cross arm, and the rotatable connection position is offset from the axis of the power ring. The first column is rotatably disposed on the power ring, and the second column is rotatably disposed on the slide block.

[0012] The beneficial effects of this invention are as follows: By positioning the axis of the center hole of the I-beam wheel and using this axis as a reference, the power ring drives the rangefinder to move in a circular motion around the I-beam wheel. This facilitates direct measurement of the distance between the rangefinder and the outer circumference of the side plate of the I-beam wheel. Based on the measurement range, the positional accuracy of the center hole of the I-beam wheel can be quickly detected directly. By using the power ring to synchronously drive the top pressure body in a circular motion, when the top pressure body moves to the position of the drive hole on the I-beam wheel, the propulsion structure pushes the top pressure body and makes it coaxial with the drive hole. Based on the position of the top pressure body moving in the radial direction of the power ring, the positional accuracy of the drive hole can be detected. This achieves rapid and automatic detection of the I-beam wheel, simplifies the operation, and makes the equipment suitable for mass production needs. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 9As shown, the present invention provides a quality inspection device for I-beam wheels, comprising a power ring 2 capable of self-rotation and a clamping structure 3 for fixing the I-beam wheel 1. The clamping structure 3 makes the axis of the central hole of the I-beam wheel 1 coincide with the axis of the power ring 2. The power ring 2 is provided with a rangefinder 4 and a support body 5. The rangefinder 4 is used to detect the distance between itself and the outer circumference of the side plate of the I-beam wheel 1. The support body 5 is provided with a movable sleeve 6 that slides in the radial direction of the power ring 2 and a distance sensor 7 for detecting the position of the movable sleeve 6 on the support body 5. The bottom of the movable sleeve 6 is provided with a pushing structure 8, and the bottom of the pushing structure 8 is provided with a top pressure body 9. The top pressure body 9 is used to detect the position of the drive hole on the side plate of the H-beam wheel 1. The shape of the top pressure body 9 is either conical or spherical.

[0019] In this invention, both the power ring 2 and the clamping structure 3 can be mounted on an external workbench. The power ring 2 can be driven to rotate by a motor, and it provides support for the rangefinder 4, support body 5, and movable sleeve 6. The clamping structure 3 is mainly used to fix and position the I-beam wheel 1, so that the axis of the central hole on the I-beam wheel 1 can coincide with the axis of the power ring 2. In this way, when the power ring 2 rotates, the distance between the rangefinder 4 and the support body 5 on the power ring 2 and the axis of the central hole of the I-beam wheel 1 remains constant. The height position of the rangefinder 4 is... The height position of the upper side plate of the I-beam wheel 1 corresponds to the vertical position of the I-beam wheel 1 side plate. When the axis of the I-beam wheel 1 is vertical, the distance measuring instrument 4 is aligned with the height position of the side plate of the I-beam wheel 1 in the vertical direction. When the axis of the I-beam wheel 1 is horizontal, the distance measuring instrument 4 is aligned with the position of the side plate of the I-beam wheel 1 in the horizontal direction. In other words, the distance measuring instrument 4 is located on the surface of the side plate of the I-beam wheel 1. If the position of the center hole of the I-beam wheel 1 is off-center, the distance between the distance measuring instrument 4 and the outer circumference of the side plate of the I-beam wheel 1 will change when the power ring 2 and the distance measuring instrument 4 rotate. That is, the value measured by the distance measuring instrument 4 is not the specified value.

[0020] The support body 5 can provide support for the movable sleeve 6 and guide the movable sleeve 6 so that the movable sleeve 6 can move in the radial direction of the power ring 2. The distance sensor 7 can directly measure the lateral distance of the movable sleeve 6 on the support body 5. In order to facilitate recording, data analysis and equipment operation control, a controller can be set on the workbench to control the rotation of the power ring 2, the fixing function of the clamping structure 3 on the I-beam wheel 1, the measurement of the rangefinder 4, the measurement of the distance sensor 7 and the switching of the propulsion structure 8.

[0021] In use, the I-beam wheel 1 is fixed on the clamping structure 3. The power ring 2 rotates, driving the rangefinder 4, support body 5, and movable sleeve 6 on it to rotate synchronously. The rangefinder 4 directly measures the distance between the outer circumference of the side plate of the I-beam wheel 1 and the rangefinder 4. When the measured value is within the specified range, the positional accuracy of the center hole of the I-beam wheel 1 is qualified. When the measured value exceeds the specified range, the positional accuracy of the center hole of the I-beam wheel 1 is unqualified. The support body 5, movable sleeve 6, distance sensor 7, propulsion structure 8, and top pressure body 9 move in a circular motion synchronously. When the propulsion structure 8 is energized with a positive current, it will extend and push the top pressure body 9 downward. The bottom of the top pressure body 9 contacts the upper surface of the I-beam wheel 1. As the power ring 2 rotates, the top pressure body 9 slides on the upper surface of the I-beam wheel 1. When the top pressure body 9 is pressed down, the top pressure body 9 slides on the upper surface of the I-beam wheel 1. When the body 9 moves to the position of the drive hole on the I-beam wheel 1, the bottom of the top pressing body 9 can slide into the drive hole by utilizing the shape characteristics of the top pressing body 9, and the axis of the top pressing body 9 will coincide with the axis of the drive hole. At this time, if the distance between the drive hole and the axis of the center hole of the I-beam wheel 1 exceeds the specified range, the movement distance of the top pressing body 9 in the radial direction along the power ring 2 will be outside the specified range. The top pressing body 9 drives the movable sleeve 6 to slide on the support body 5 through the propulsion structure 8. The distance sensor 7 detects that the movement distance of the movable sleeve 6 exceeds the specified range. However, if the position of the drive hole is within the specified range, the detection value of the distance sensor 7 is within the specified range. Thus, the position of the drive hole is detected by utilizing the shape characteristics of the top pressing body 9 and its automatic alignment function with the drive hole.

[0022] It should be noted that regardless of whether the shape of the pressure body 9 is conical or spherical, when subjected to the downward thrust of the propulsion structure 8, if the pressure body 9 is not coaxial with the drive hole, the side of the pressure body 9 will contact one side of the inner wall of the drive hole. The force between them will provide a tilted reverse thrust for the pressure body 9, causing it to move until it is coaxial with the drive hole. Furthermore, when the pressure body 9 is coaxial with the drive hole and the power ring 2 continues to rotate, the reaction force generated by the drive hole on the pressure body 9 will cause it to overcome the force of the propulsion structure 8 and move upward, thus facilitating... The top pressure body 9 disengages from the drive hole and detects the next drive hole. Alternatively, the push structure 8 can be retracted by providing a reverse current to the push structure 8, causing the top pressure body 9 to disengage from the drive hole. When the top pressure body 9 rotates with the power ring 2 and deviates from the drive hole, the push structure 8 applies a positive current and provides a downward force to the top pressure body 9 again, so as to detect the next drive hole. Since the position detection of the movable sleeve 6 and the top pressure body 9 is mainly based on the distance the movable sleeve 6 moves on the support body 5, the initial position of the movable sleeve 6 on the support body 5 is the standard position of the drive hole.

[0023] By positioning the axis of the central hole of the I-beam wheel 1 and using this axis as a reference, the power ring 2 drives the rangefinder 4 to move in a circular motion around the I-beam wheel 1. This facilitates direct measurement of the distance between the rangefinder 4 and the outer circumference of the side plate of the I-beam wheel 1. Based on the measurement range, the positional accuracy of the central hole of the I-beam wheel 1 can be quickly detected directly. By using the power ring 2 to synchronously drive the pressure body 9 in a circular motion, when the pressure body 9 moves to the position of the drive hole on the I-beam wheel 1, the propulsion structure 8 pushes the pressure body 9 and makes it coaxial with the drive hole. Based on the position of the pressure body 9 moving in the radial direction of the power ring 2, the positional accuracy of the drive hole can be detected. This achieves rapid and automatic detection of the I-beam wheel 1, simplifies the operation, and makes the equipment suitable for mass production needs.

[0024] Furthermore, a column 10 is provided on the side wall of the power ring 2, a cross arm 11 is provided on the top of the column 10, a support frame 12 is provided on the side wall of the column 10, a support body 5 is provided on the cross arm 11, and a rangefinder 4 is provided on the support frame 12. The rangefinder 4 is set to one or two. When there is one rangefinder 4, the support frame 12 slides vertically on the column 10, so that the rangefinder 4 can detect either of the two side plates on the I-beam wheel 1. When there are two rangefinders 4, the two rangefinders 4 detect the two side plates on the I-beam wheel 1 respectively.

[0025] The axis of column 10 is set parallel to the axis of power ring 2. The cross arm 11 can support the support body 5, and the support frame 12 can support the rangefinder 4. When the power ring 2 rotates, the power ring 2 drives the rangefinder 4 and the support body 5 to rotate synchronously through column 10, cross arm 11 and support frame 12. Since the I-beam wheel 1 has two side plates, when the number of rangefinders 4 is set to one, in order to facilitate the detection of two side plates, the support frame 12 can be slidably set on column 10. In this way, after the rangefinder 4 completes the measurement of one side plate, it can move to the corresponding position of the other side plate and measure that side plate. When the number of rangefinders 4 is set to two, the two rangefinders 4 can measure two side plates at the same time.

[0026] Furthermore, the propulsion structure 8 includes a support sleeve 13 and a movable column 14 that are nested together and can slide relative to each other. The support sleeve 13 and the movable column 14 are respectively disposed on the movable sleeve 6 and the top pressure body 9. A coil 15 is disposed on the inner wall of the support sleeve 13, and a magnet 16 is disposed inside the coil 15. The magnet 16 is connected to the movable column 14.

[0027] Coil 15 can be connected to an external power source. An external controller can control the direction of the current in coil 15. When a positive current flows through coil 15, the magnetic field it generates is the same as the magnetic field around the magnetic body 16. Coil 15 pushes the magnetic body 16 to move, which in turn drives the pressure body 9 to move downward through the movable column 14. When a reverse current flows through coil 15, coil 15 attracts the magnetic body 16 upward. At this time, the pressure body 9 moves upward and resets.

[0028] In some embodiments, to measure the diameter of the drive hole, the top pressure body 9 can be tapered, and a pressure measuring plate 37 can be added between the movable column 14 and the magnetic body 16. The pressure measuring plate 37 can detect the force provided by the coil 15 to the magnetic body 16. When the top pressure body 9 is coaxially aligned with the drive hole, the top pressure body 9 moves downward, and there is a certain distance between the magnetic body 16 and the coil 15. Since the force between the coil 15 and the magnetic body 16 is related to the distance between them, the force between the magnetic body 16 and the movable column 14 can be measured by the pressure measuring plate 37, thereby measuring the relative position between the coil 15 and the magnetic body 16. This facilitates the measurement of the depth of the bottom of the top pressure body 9 inserted into the drive hole. Combined with the tapered shape of the top pressure body 9, it is convenient to directly measure the inner diameter of the drive hole. The pressure measuring plate 37 can be an electronic pressure gauge or other structure capable of measuring pressure.

[0029] The support sleeve 13 and the movable column 14 can isolate the coil 15 and the magnet 16 inside to prevent magnetic leakage.

[0030] Furthermore, a ramp 17 and a slider 18 are provided between the movable sleeve 6 and the support sleeve 13. The ramp 17 is connected to the movable sleeve 6, and the slider 18 is connected to the support sleeve 13. The slider 18 slides on the ramp 17, and the sliding direction of the slider 18 is perpendicular to the radial movement trajectory of the movable sleeve 6. The ramp 17 and the slider 18 are connected by a spring 19, and both the ramp 17 and the slider 18 are equipped with electromagnetic suction plates 20 that work together.

[0031] When energized, the two electromagnetic chucks 20 attract each other, thus fixing the relative positions of the ramp 17 and the slider 18. When the push structure 8 pushes the top pressure body 9 down and aligns it with the drive hole, the two electromagnetic chucks 20 are in a state of mutual attraction. At this time, the slider 18 cannot move on the ramp 17. After the drive hole measurement is completed, the two electromagnetic chucks 20 are de-energized. At this time, the two electromagnetic chucks 20 are allowed to separate from each other. The power ring 2 rotates and drives the cross arm 11 and the movable sleeve 6 to deviate from the drive hole. At this time, the locking of the top pressure body 9 by the drive hole will restrict the slider 18, causing the slider 18 to move relative to the ramp 17. Since the slider 18 slides at an angle on the ramp 17, the slider 18 can gradually lift the top pressure body 9 and separate it from the drive hole in the vertical direction. Thus, the reverse restriction of the top pressure body 9 by the drive hole will not interfere with or hinder the rotation of the power ring 2.

[0032] It should be noted that, through an external controller, the current flow direction in the propulsion structure 8 can be controlled after the slider 18 slides a certain distance, so that the propulsion structure 8 reverses and lifts the top pressure body 9. Thus, the reverse lifting of the top pressure body 9 by the propulsion structure 8 and the lifting of the top pressure body 9 by the slider 18 are combined. The two functions can be used simultaneously or only one can be used.

[0033] In some embodiments, the inclination of the slider 18 can be set even lower. When the push structure 8 provides thrust to the top pressure body 9 and transmits it in the opposite direction to the slider 18, the horizontal component of the slider 18 is small, and the slider 18 cannot slide on the ramp 17. Only when the top pressure body 9 and the drive hole are misaligned and separated on the horizontal plane can the horizontal resistance provided by the drive hole to the top pressure body 9 enable the slider 18 to move on the ramp 17. At this time, the attraction force between the two electromagnetic chucks 20 can be set to a maximum value. When the top pressure body 9 and the drive hole are misaligned and the resistance provided by the drive hole to the top pressure body 9 exceeds the attraction force between the two electromagnetic chucks 20, the two electromagnetic chucks 20 can also separate from each other. Thus, the two electromagnetic chucks 20 can be directly controlled without a controller. The spring 19 can provide a restoring force for the slider 18.

[0034] Furthermore, the movable sleeve 6 is provided with a reset structure 21 for providing a reset force to the movable sleeve 6. The reset structure 21 includes a second coil 22, a magnetic post 23 located inside the second coil 22, a connecting plate 24 disposed on the outer wall of the magnetic post 23, and two conductive plates 25 disposed on each side wall of the connecting plate 24. The second coil 22 is composed of several coaxially arranged arc-shaped wires. The second coil 22 is fixedly disposed relative to the support body 5. The magnetic post 23 is fixedly disposed relative to the movable sleeve 6 through the connecting plate 24. The polarity of the two conductive plates 25 on one side of the connecting plate 24 is opposite to the polarity of the two conductive plates 25 on the other side. The two conductive plates 25 on each side of the connecting plate 24 are electrically connected to the two ends of the arc-shaped wires and can be slidably disposed relative to each other.

[0035] Several arc-shaped wires on coil 22 are arranged along the moving direction of movable sleeve 6 on support body 5, and the two ends of the arc-shaped wires can be used with two conductive plates 25 on each side of connecting plate 24. The total length of conductive plates 25 on both sides of connecting plate 24 is greater than the length of the arc-shaped wires, thus ensuring that the arc-shaped wires are always connected to the circuit. The polarities of the conductive plates 25 on both sides of connecting plate 24 are opposite, that is, one conductive plate 25 on the left side of connecting plate 24 is connected to the positive terminal of the external circuit, and the corresponding conductive plate 25 on the right side of connecting plate 24 is connected to the negative terminal of the external circuit. In the initial state, the magnetic column 23 is located on the coil At the middle position of 22, the number of arc-shaped wires on both sides of the magnetic post 23 is the same. The magnetic force generated by the arc-shaped wires cancels out the effect of the magnetic post 23. When the movable sleeve 6 moves to the left, the movable sleeve 6 drives the magnetic post 23 and the four conductive plates 25 to move to the left synchronously through the connecting plate 24. At this time, the number of arc-shaped wires connected to the two conductive plates 25 on the left side of the connecting plate 24 decreases, and the number of arc-shaped wires on the right side of the connecting plate 24 increases. The magnetic post 23 is subjected to a force to the right as a whole. Similarly, when the movable sleeve 6 moves to the right, the magnetic post 23 is subjected to a force to the left as a whole. Thus, this structure provides a restoring elastic force for the movable sleeve 6.

[0036] When the distance sensor 7 is a rangefinder, it can measure the offset of the drive hole by directly measuring the movement position of the movable sleeve 6 or the magnetic column 23. In this case, the four conductive plates 25 on both sides of the connecting plate 24 can be connected to the same circuit. When the distance sensor 7 is an ammeter, the conductive plates 25 on both sides of the connecting plate 24 are connected to two different circuits. The two conductive plates 25 on one side of the connecting plate 24 are connected to the same circuit as the distance sensor 7. In this way, the distance sensor 7 measures the current between the corresponding two conductive plates 25, thereby measuring the offset of the magnetic column 23 and the movable sleeve 6. Of course, the distance sensor 7 can also be other structures that can measure the position of the movable sleeve 6, all of which are within the protection scope of this case.

[0037] Furthermore, the reset structure 21 also includes an isolation cylinder 26, which is fixedly connected to the support body 5. The coil 22 is fixed on the inner wall of the isolation cylinder 26. A notch 28 is provided at the bottom of the isolation cylinder 26. An isolation cylinder 27 is slidably sleeved on the outer wall of the isolation cylinder 26. The connecting plate 24 passes through the notch 28 and is fixedly connected to the isolation cylinder 27. The isolation cylinder 27 is fixedly connected to the movable sleeve 6.

[0038] Isolation cylinder 1 26 and isolation cylinder 27 can isolate and protect the internal structure to prevent magnetic leakage. At the same time, when the movable sleeve 6 moves, it will drive isolation cylinder 27 to slide on isolation cylinder 1 26. Furthermore, isolation cylinder 27 will drive the magnetic column 23 and the four conductive plates 25 to move synchronously through the connecting plate 24.

[0039] Furthermore, the clamping structure 3 includes a fixed post 29 and a spindle 32 rotatably located inside the fixed post 29. Two support groups are arranged opposite each other on the outer wall of the fixed post 29. Each support group includes a transmission wheel 30 rotatably mounted on the fixed post 29 and a support arm 31 mounted on the outer wall of the transmission wheel 30. Part of the transmission wheel 30 is located inside the fixed post 29. Two drive wheels 33 are arranged on the outer wall of the spindle 32. The drive wheels 33 are connected to the corresponding transmission wheels 30 in a transmission connection. The transmission wheel 30 and the support arm 31 are both inclined, and the inclination directions of the support arm 31 in the two support groups are opposite. The support arm 31 is arc-shaped, and the outer end of the support arm 31 is set as a right angle, which is used in conjunction with the inner angle of the center hole of the I-beam wheel 1.

[0040] The fixed column 29 is fixed on the external workbench. The spindle 32 can be driven to rotate by a motor. When the I-beam wheel 1 is placed on the outside of the clamping structure 3, the spindle 32 is rotated. The spindle 32 can drive several transmission wheels 30 to rotate through the drive wheel 33. The transmission wheels 30 drive the support arm 31 to rotate, thereby driving the support arm 31 from a position close to the outer wall of the fixed column 29 to a position away from the fixed column 29. The support arm 31 can contact the inner wall of the center hole of the I-beam wheel 1. Several support arms 31 in the support group provide synchronous external support to the inner wall of the center hole of the I-beam wheel 1, thereby realizing the axis fixing function and clamping function of the center hole. The two support groups move synchronously, thereby improving the firmness of clamping the I-beam wheel 1.

[0041] By utilizing the inclined arrangement of the transmission wheel 30 and the support arm 31, when the support arm 31 rotates outward, the right angle at the outer end of the support arm 31 can be used to match the inner angle position of the central hole. The inclination directions of the support arms 31 in the two support groups are opposite, so the two support groups can achieve a synchronous external support and fixation effect on the I-beam wheel 1 in the vertical direction, realizing multi-directional fastening of the I-beam wheel 1. Since the transmission wheel 30 is inclined, the shape of the drive wheel 33 can be adjusted to a conical shape to facilitate mutual transmission between the transmission wheel 30 and the drive wheel 33.

[0042] Furthermore, a slide block 36 is provided on the power ring 2, which slides along the trajectory of the power ring 2. A column 35 parallel to the column 10 is provided on the slide block 36. A cross arm 34 is provided on the column 35. The end of the cross arm 34 is rotatably connected to the end of the cross arm 11, and its rotatable connection position is offset from the axis of the power ring 2. The column 10 is rotatably set on the power ring 2, and the column 35 is rotatably set on the slide block 36.

[0043] The slide block 36 can slide on the power ring 2 driven by an external motor. The cross arm 34, the column 35 and the slide block 36 can provide auxiliary support for the cross arm 11, thereby improving the strength and stability of the overall structure. Since the connection position between the cross arm 34 and the cross arm 11 is off the axis of the power ring 2, when the slide block 36 moves toward the column 10, the slide block 36 will pull the cross arm 11 away from the axis of the power ring 2 through the column 35 and the cross arm 34. The column 10 rotates on the power ring 2, thereby moving the cross arm 11 and its structure away from the I-beam wheel 1, which facilitates the disassembly and assembly of the I-beam wheel 1.

[0044] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
