Description

Technical Field

[0001] The present invention relates to the field of detection and correction equipment, in particular to an automatic detection and correction machine for H wheels. Background Art

[0002] Steel cord is the skeleton material of radial tires and is mainly used in the production of rubber products such as passenger car tires, light truck tires, heavy truck tires, engineering machinery tires, and aircraft tires. It is a conventional raw material for tire manufacturers. The H wheel is a wire-carrying tool used for the operation and transportation of semi-finished and finished products of steel cord. After the H wheel is manufactured, its core parameters of form and position tolerances need to be tested, including circular runout, which is used to detect the eccentricity of the outer circle and end face of the rim relative to the axial hole to ensure uniform tension when the coil is retracted and unreeled; coaxiality, which is used to verify whether the central axes of the rim, spoke plate, and axial hole coincide to prevent shaking during operation; flatness, which is used to detect whether the end face of the rim is flat and whether it will affect the alignment of the coil; and roundness, which is used to detect whether the outer circle of the rim is a standard circle to avoid local stress concentration in the coil. Currently, the detection and correction of H wheel parameters mainly rely on manual processing, which is inefficient and has poor accuracy. Summary of the Invention

[0003] In response to the problems existing in the prior art, the present invention provides an H-wheel automatic detection and correction machine, which is used to detect the spacing and runout of the webs on both sides of the H-wheel and correct them, and to detect whether the circular runout of the H-wheel center tube is within the tolerance. The loading is automatically inspected and corrected one by one, and qualified and unqualified products are automatically sorted and conveyed to realize automated operation.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: The H-wheel automatic inspection and correction machine includes a feeding device, a material receiving and unloading device, and a detection and correction device.

The clamping mechanism is located on the left and right sides of the receiving plate at the top of the material receiving and unloading device. The detection and correction mechanism is located at the front side of the receiving plate. The feeding device includes a track ramp and a release mechanism, and the release mechanism is installed on the lower end of the track ramp; The material receiving and unloading device includes a V-shaped receiving plate, a flipping mechanism, a lifting mechanism and a receiving track. The receiving plate is located at the front side of the lower end of the track slope plate. The flipping mechanism is installed on the left and right sides of the lifting plate at the top of the lifting mechanism. The end shafts are provided at both ends of the bottom of the receiving plate and are rotatably connected to the flipping mechanism. The receiving tracks are installed below the feeding device and below the detection and correction mechanism, that is, on the front and back sides of the lifting mechanism.

[0005] A further improvement is that the release mechanism includes a first gantry, a second gantry, a first linear actuator, a second linear actuator, a first crossbar, and a second crossbar. The first gantry is located in front of the second gantry. The first and second linear actuators are mounted on the crossbars of the first and second gantry, respectively, with their telescopic rods facing downward. The first and second crossbars are fixed to the bottom ends of the telescopic rods of the first and second linear actuators, respectively. The ends of the first and second crossbars are slidably connected to the vertical rods of the first and second gantry via guide sleeves or linear bearings. The initial height of the first crossbar is lower than the height of the spokes of the H-wheel to be released. The second crossbar is located between the two frontmost H-wheels to be released and its initial height is higher than the height of the spokes of the H-wheel to be released. The first linear actuator drives the first crossbar to raise to release the frontmost H-wheel, while the second linear actuator drives the second crossbar to lower to prevent the second H-wheel from passing, resetting the system in sync. The two release mechanisms release the H-wheels one by one, achieving high efficiency through coordinated operation.

[0006] A further improvement is to provide two or more rails spaced longitudinally on the track ramp to form at least two tracks adapted to H wheels of different axle lengths. The multi-track design accommodates different types of H wheels for feeding inspection.

[0007] A further improvement is that the clamping mechanism includes a drive motor located on the right side of the connector plate, a left clamping head, a right clamping head located on the left side of the connector plate, and a third linear actuator. The left clamping head is fixed to the output shaft of the drive motor, while the right clamping head is pivotally connected to the telescopic rod of the third linear actuator. The third linear actuator pushes forward to clamp various H-type wheels with different center barrel lengths. The drive motor drives the H-type wheels to rotate for detection and calibration.

[0008] A further improvement is that the left and right chucks are of conical structure, inserted into the shaft holes at both ends of the H wheel, and matched with models of different hole diameters for clamping.

[0009] A further improvement is that the detection and correction mechanism includes a mounting plate, a fourth linear actuator, an infrared detector group, a fifth linear actuator, a translation plate and a correction wheel group, the fourth linear actuator is arranged on the rear side of the mounting plate close to the side of the H wheel clamped by the clamping mechanism, the infrared detector group includes an infrared detector 1 and an infrared detector 2 for detecting the spacing and runout of the webs at both ends of the H wheel, and an infrared detector 3 for detecting the runout of the center cylinder of the H wheel, the mounting frame for fixing the infrared detector group is connected to the bottom end of the telescopic rod of the fourth linear actuator, the The fifth linear actuator is arranged on the front side of the bottom of the mounting plate, away from the H wheel clamped by the clamping mechanism. The translation plate is slidably connected to the mounting plate through the forward and backward slide rails. The front side of the translation plate is fixed on the telescopic rod of the fifth linear actuator. The correction wheel group includes the left outer wheel, left inner wheel, right inner wheel and right outer wheel of the web plates at both ends of the correction H wheel. The left and right linear module one is installed at the bottom of the translation plate. Two sliders are provided on the linear module one. The mounting frame for fixing the left inner wheel and the right inner wheel, and the mounting frame for fixing the right inner wheel and the right outer wheel are respectively connected to the two sliders of the linear module one.

[0010] A further improvement is that there are two sets of left inner wheels and right inner wheels, which are arranged on the same mounting frame. The webs of two types of H wheels with different lengths of center tubes are corrected.

[0011] A further improvement involves mounting a second left-right linear module at the bottom of the mounting plate, with an adjustment plate positioned on the slider of the second linear module. The fifth linear actuator is mounted on the adjustment plate, and a forward-backward slide rail is mounted at the bottom of the adjustment plate. The translation plate is connected to the adjustment plate via the forward-backward slide rail. When inspecting and calibrating different H-wheel models, first adjust the initial position.

[0012] A further improvement involves mounting the sixth linear actuator of the lifting mechanism at the bottom of the support plate. The linear actuator's telescopic rod extends through the support plate, its top end fixed to the lifting plate above. Two sets of flipping mechanisms are mounted on the left and right sides of the lifting plate, with their rotating components connected to the end shafts at the bottom ends of the receiving plate. The flipping mechanisms selectively tilt the receiving plate to either side, routing the H-wheels on it to the receiving tracks on different sides, completing the automatic sorting of qualified and unqualified products.

[0013] A further improvement is that the driving mechanism is a telescopic rod of the cylinder connected to a rack, and the rack is engaged with the gears on the end shafts at both ends of the bottom of the connecting plate. Beneficial effects

[0015] 2. The detection and correction device uses an infrared detector to detect whether the spacing and runout of the webs on both sides of the rotating H wheel and the circular runout of the center cylinder are within the tolerance, and uses the correction wheel to correct the webs accurately and efficiently.

[0016] 3. After the H-wheel inspection and calibration, the final product qualification is obtained.

[0021] The material receiving and unloading device 2 includes a V-shaped connecting plate 21, a turning mechanism 22, a lifting mechanism 23, and a receiving track 24. The connecting plate 21 is located at the front end of the track ramp 11. The sixth linear actuator 232 of the lifting mechanism 23 is mounted on the bottom of the support plate 233. The telescopic rod of the sixth linear actuator 232 passes through the support plate 233 and its top end is fixed to the lifting plate 231 above. Two sets of turning mechanisms 22 are respectively mounted on the left and right sides of the lifting plate 231. The driving members of the two turning mechanisms 22 are respectively connected to the end shafts provided at the bottom ends of the connecting plate 21. The turning mechanism 22 is a telescopic rod of a cylinder 221 connected to a rack 222, which meshes with gears 223 on the end shafts at the bottom ends of the connecting plate. The receiving track 24 is installed below the feeding device 1 and below the detection and correction mechanism 32, that is, on the front and rear sides of the lifting mechanism. To ensure a more stable ascent and descent of the lifting platform carrying the receiving plate and the tilting mechanism, the lifting platform is equipped with guide posts 234 on the left and right sides of the linear actuator's telescopic rod. These guide posts 234 extend through the support plate 233 below. The receiving track 24 is constructed with two side baffles 242 mounted on a sloped panel 241, and a baffle 243 at the end. The baffles 242 have a flared start.

[0022] Working process: Place the H wheel to be inspected on the track ramp, turn on the equipment, and the first linear actuator of the release mechanism drives the first crossbar to lift and release upward, while the second linear actuator drives the second crossbar downward to block. At this time, only the H wheel at the front end rolls down to the receiving plate of the material receiving and unloading device (when the first and second crossbars are driven to reset, the second H wheel at the front end moves to the front end and is blocked by the first crossbar to prepare for the next round of operation). The H wheel that falls on the receiving plate is clamped by the left and right clamps under the push of the third linear actuator of the clamping mechanism. The lifting mechanism of the material receiving and unloading device drives the receiving plate to descend, and the fourth linear actuator of the detection and correction mechanism pushes the infrared detector group downward to the upper position on the front side of the H wheel. The H wheel rotates under the drive motor of the clamping mechanism. During the rotation, infrared detectors 1 and 2 detect whether the spacing and runout of the webs at both ends of the H wheel are within the tolerance range. Infrared detector 3 detects whether the runout of the center cylinder of the H wheel is within the tolerance range. If the spacing and runout of the webs at both ends of the H wheel are not within the tolerance range, the fifth linear actuator pushes the translation plate to drive the correction wheel group to move to the H wheel position for internal pressure or external extrusion correction. The parameters after correction and detection are used to determine whether the product is qualified. Then, the information transmission equipment controller synchronously drives the fourth linear actuator to drive the infrared detector group, and the fifth linear actuator drives the correction wheel group to reset. The lifting mechanism drives the receiving plate upward, the clamping mechanism releases the H wheel, and the H wheel falls back on the receiving plate. The lifting mechanism drives the receiving plate downward until it is close to the receiving track. Depending on whether the H wheel is qualified, the cylinder solenoid valve at one end of the flipping mechanism is opened, pushing the lifting plate to flip to the front or back side, and the H wheel is automatically sorted.
