Description

Technical Field

[0001] The invention relates to the technical field of wheel detection, in particular to automatic wheel detection equipment. Background Art

[0002] Wheels are composed of tires and hubs. However, the size of the rim plays an important role in the hub when installing the tire. Therefore, the detection of the widest part of the rim is crucial for the selection and installation of tires, because it directly affects the size of the tire and the handling performance of the vehicle. The size of the widest part of the rim also affects the appearance and wind resistance of the vehicle. A rim that is too wide may cause the outer side of the tire to bulge, affecting the appearance of the vehicle and increasing air resistance, while a rim that is too narrow may cause damage to the side of the tire.

[0003] Since the rims of most wheels are inclined or curved, the thickness of rims of different shapes are not consistent. However, due to the different inclination angles, the thickness of the rim needs to be detected perpendicular to the inclination angle of the rim, which is very troublesome to measure and prone to errors. However, the thickness of the curved rim surface is easily inconsistent due to the difference in manufacturing processes. However, the installation of the wheel tire requires the detection of the size of the thickest part of the rim, which not only requires multiple measurements but also requires the adaptation to the curvature of the rim surface. The operation is relatively complicated, the detection cost is extremely high, and the operation difficulty requirements for the staff are relatively high. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-8, an embodiment of the present invention: an automatic wheel detection device, comprising a workbench 1, a clamping mechanism 2 is arranged at the bottom of the workbench 1, an electric screw slide 8 is arranged on the side of the workbench 1, a U-shaped telescopic frame 7 is fixedly arranged at the output end of the electric screw slide 8, a reciprocating mechanism 6 is arranged on the side wall of the U-shaped telescopic frame 7, a measuring mechanism 4 is arranged at the bottom of the inner side wall of the U-shaped telescopic frame 7, a one-way mechanism 5 is arranged at the bottom top of the measuring mechanism 4, the measuring mechanism 4 comprises a first electric push rod 41, a first contact plate 42, two telescopic shafts 43, two first contact springs 44, two contact disks 45, an L-shaped measuring rod 46, a measuring assembly, a second electric push rod 413, a second contact plate 411, an L-shaped measuring rod 46, two second contact springs 49 and a third contact plate 410, the first contact plate 42 is provided with a reciprocating mechanism 6, and the second contact plate 42 is provided with a reciprocating mechanism 6. An electric push rod 41 is fixedly set on the inner wall of the U-shaped telescopic frame 7, the first contact plate 42 ball head is set on the end of the output shaft of the first electric push rod 41, the two telescopic shafts 43 are fixedly set on the first contact plate 42, the two first contact springs 44 are sleeved on the outer walls of the two telescopic shafts 43, the L-shaped measuring rod 46 is fixedly set on the ends of the two telescopic shafts 43, the two contact plates 45 are fixedly set on the side wall of the L-shaped measuring rod 46 away from the telescopic shaft 43, the second electric push rod 413 is fixedly set on the inner wall of the U-shaped telescopic frame 7, the second contact plate 411 ball head is set on the end of the output shaft of the second electric push rod 413, the two second contact springs 49 are fixedly set on the side wall of the second contact plate 411, and the third contact plate 410 is fixedly set on the other end of the two second contact springs 49. First, place the wheel hub to be measured on the workbench 1, and then clamp and fix the wheel hub by the clamping mechanism 2, and then drive the measuring mechanism 4 to move down to a suitable position by the electric screw slide 8, and then measure the thickness of the rim on the wheel hub by the measuring mechanism 4. If the wheel hub is an inclined rim, the rim thickness can be directly measured. If it is a bracket-shaped arc rim, the measuring mechanism 4 automatically determines and then synchronously drives the one-way mechanism 5 to work in conjunction with the reciprocating mechanism 6 to measure the thickness of the thickest position of the rim, which is convenient for the subsequent installation of the tire.

[0017] Specifically, the one-way mechanism 5 includes a second wedge block 51, an L-shaped mounting plate 52, a compression spring 53, a one-way gear 54, a one-way rack 55, a connecting plate 56, a connecting shaft 57, a sliding rod 58, a baffle 59, a plug shaft 510, a limit shaft 511, a pawl 512, a torsion spring 513, a rotating shaft 514 and a ratchet 515. The L-shaped mounting plate 52 is fixedly arranged on the top of the third contact plate 410, and the plug shaft 510 is movably plugged on the L-shaped mounting plate 52. The second wedge block 51 is fixedly arranged at the bottom of the plug shaft 510, the baffle 59 is fixedly arranged on the top of the L-shaped mounting plate 52, and the compression spring 53 is fixedly arranged on the The side wall of the baffle 59, the sliding rod 58 is slidably set on the top of the L-shaped mounting plate 52, the one-way rack 55 is fixedly set on the side wall of the sliding rod 58, the connecting plate 56 is fixedly set on the side wall of the plug-in shaft 510, the limiting shaft 511 is fixedly set on the top of the connecting plate 56, the connecting shaft 57 is rotatably set on the L-shaped mounting plate 52, the one-way gear 54 is fixedly set on the top of the connecting shaft 57, the ratchet 515 is fixedly set on the bottom of the connecting shaft 57, the rotating shaft 514 is rotatably set on the bottom of the L-shaped mounting plate 52, the pawl 512 is fixedly set on the bottom of the rotating shaft 514, and the torsion spring 513 is sleeved on the rotating shaft 514. The second wedge block 51 moves upward, driving the plug-in shaft 510 and the connecting plate 56 to move upward synchronously. The connecting plate 56 moves upward, driving the limiting shaft 511 to move synchronously. The limiting shaft 511 limits the pawl 512, so that the ratchet 515 can only rotate in one direction. The one-way gear 54 can also only rotate in one direction through the fixation of the connecting shaft 57. As a result, the one-way rack 55 can only move toward the rim direction under the action of the one-way gear 54. This ensures that when measuring the thickness of the arc rim, the thickest dimension to be measured will not be adjusted synchronously as the thickness decreases, so that the dimension of the thickest part on the rim can be measured without the need for additional manual adjustment intervention.

[0018] Specifically, the end of the second electric push rod 413 is located at the upper half of the second contact plate 411 .

[0019] Specifically, the measuring assembly includes a scale bar 47, a special-shaped frame 48, a first wedge block 414 and a resistance block 412. The scale bar 47 is fixedly set on the top of the L-shaped measuring rod 46, the special-shaped frame 48 is fixedly set on the top of the L-shaped mounting plate 52, the first wedge block 414 is plugged into the second resistance plate 411 and the third resistance plate 410, and the resistance block 412 is plugged into between the second resistance plate 411 and the third resistance plate 410. The output shaft of the first electric push rod 41 extends to drive the first contact plate 42 and the contact plate 45 to contact the inner wall of the rim, and the output shaft of the second electric push rod 413 extends to drive the second contact plate 411 and the third contact plate 410 to move toward the rim, so that the third contact plate 410 contacts the outer wall of the rim, so that the first wedge block 414 and the contact block 412 are synchronously contacted and move away from the rim. At this time, the thickness of the rim can be observed by observing the scale on the scale bar 47. The above is an inclined rim. If it is an arc-shaped rim, the extension of the output shaft of the second electric push rod 413 will cause the second contact plate 411 and the upper half of the third contact plate 410 to The lower part of the wheel rim is in contact with the rim, and there is still a gap between the lower part and the rim. At this time, the contact block 412 has not moved, so the secondary rim shape is judged to be a bracket-shaped arc. It is realized that the arc-shaped and inclined rims can be automatically judged and their measurement methods can be distinguished. It is practical, and different measurement methods are used for different shapes, and the measurement effect is good. Due to the setting of the ball head connection, it is also realized that the inclined rim can adapt to the angle, so that the third contact plate 410 and the first contact plate 42 are perpendicular to the rim surface, so that the measured thickness is more accurate, the error is small, and no manual adjustment is required. It is suitable for the measurement of rims with various inclination angles and has strong applicability.

[0020] Specifically, the clamping mechanism 2 includes a turntable 21, four arc-shaped grooves 22, four limit columns 23, four limit channels 24, four clamping rods 25, four arc plates 26, a clamping motor 27 and a fixed plate 28. The clamping motor 27 is fixedly arranged at the bottom of the workbench 1, and the fixed plate 28 is fixedly arranged at the top of the workbench 1. The turntable 21 is fixedly arranged at the end of the output shaft of the clamping motor 27. The four arc-shaped grooves 22 are arranged on the turntable 21 in an equidistant circular array. The four limit channels 24 are fixedly arranged on the top of the fixed plate 28 in an equidistant circular array. The four clamping rods 25 are respectively slidably arranged in the four limit channels 24. The four limit columns 23 are fixedly arranged on the top of the corresponding clamping rods 25, and the four arc plates 26 are respectively fixedly arranged at the ends of the corresponding clamping rods 25. The output shaft of the clamping motor 27 rotates to drive the turntable 21 and the arc groove 22 to rotate. The rotation of the turntable 21 drives the limiting column 23 to move along the arc groove 22. The movement of the limiting column 23 drives the clamping rod 25 to move along the limiting channel 24. The movement of the clamping rod 25 drives the arc plate 26 to clamp the wheel hub. This achieves a good clamping effect for wheel hubs of different sizes, and is highly practical.

[0021] Specifically, the reciprocating mechanism 6 includes a hinged plate 61, two U-shaped connecting frames 62, a reciprocating screw rod 63, a telescopic column 64, a driving motor 65, a mounting spring 66, a side plate 67, a cross plate 68, a slide groove 69, a first bevel gear 610, a second bevel gear 611, two L-shaped sliding plates 612, a long plate 613, two L-shaped limit frames 614 and a fixed block 615, one end of the hinged plate 61 is hingedly set at the end of the abutment block 412, one end of the two U-shaped connecting frames 62 is fixedly set on the side wall of the hinged plate 61, the telescopic column 64 is fixedly set at the bottom of the hinged plate 61, and the telescopic column 64 is located at the top of the workbench 1 to slide, and the two L-shaped sliding plates 612 are fixedly set on the two U-shaped connecting frames 6 2, the driving motor 65 is fixedly arranged at one end of two L-shaped sliding plates 612, the transverse plate 68 is fixedly arranged on the side wall of the U-shaped telescopic frame 7, the slide groove 69 is arranged on the transverse plate 68, the first bevel gear 610 is fixedly arranged on the end of the output shaft of the driving motor 65, the two L-shaped limit frames 614 are fixedly arranged on the side wall of the U-shaped telescopic frame 7, the long plate 613 is fixedly arranged on the top of the two L-shaped limit frames 614, the fixed block 615 is fixedly arranged on the side wall of the U-shaped telescopic frame 7, the reciprocating screw rod 63 is rotatably arranged at the bottom of the fixed block 615, the second bevel gear 611 is fixedly arranged at the bottom of the reciprocating screw rod 63, and the first bevel gear 610 and the second bevel gear 611 are meshed with each other. It is worth noting that the U-shaped telescopic frame 7 can not only be telescopic up and down, but also telescopic left and right. First, the U-shaped telescopic frame 7 is used to adjust the contact block 412 and the hinge plate 61 to a suitable distance from the rim, and then the contact block 412 is contacted to drive the hinge plate 61 to move, thereby driving the L-shaped limit frame 614 and the L-shaped sliding plate 612 as well as the drive motor 65 and the first bevel gear 610 to move synchronously, so that the first bevel gear 610 and the second bevel gear 611 are disengaged. If it is an arc-shaped rim, at this time, since the end of the output shaft of the second electric push rod 413 is located at the upper half of the second contact plate 411, when the third contact plate 410 contacts the surface of the arc-shaped rim, the lower half of the third contact plate 410 cannot contact the rim, so that The abutment block 412 cannot move, so that the driving motor 65 is reset by the action of the mounting spring 66, so that the first bevel gear 610 and the second bevel gear 611 are meshed, and the output shaft of the driving motor 65 rotates to drive the first bevel gear 610 to rotate, and the first bevel gear 610 drives the second bevel gear 611 to rotate, and the second bevel gear 611 rotates to drive the reciprocating screw rod 63 to rotate, and the reciprocating screw rod 63 rotates to drive the long plate 613 to move, and the movement of the long plate 613 drives the U-shaped telescopic frame 7 to extend and retract up and down, and the U-shaped telescopic frame 7 drives the whole to move, so as to measure the arc rim as a whole; the overall thickness of the arc rim can be automatically measured without manual adjustment, with a high degree of automation and simple operation, which is worthy of promotion.

[0022] Specifically, the U-shaped telescopic frame 7 is configured with a telescopic end and a fixed end, and the output end of the electric screw slide 8 is fixedly connected to the fixed end of the U-shaped telescopic frame 7 .

[0023] Working principle: first, place the wheel hub to be measured on the workbench 1, and then the output shaft of the clamping motor 27 rotates to drive the turntable 21 and the arc groove 22 to rotate, the rotation of the turntable 21 drives the limit column 23 to move along the arc groove 22, the movement of the limit column 23 drives the clamping rod 25 to move along the limit channel 24, the movement of the clamping rod 25 drives the arc plate 26 to clamp the wheel hub, and then the measuring mechanism 4 is driven down to a suitable position by the electric screw slide 8, and then the output shaft of the first electric push rod 41 is extended to drive the first contact plate 42 and the contact plate 45 to contact the inner wall of the rim, and the output shaft of the second electric push rod 413 is extended to drive the second contact plate 411 and the third contact plate 410 to move toward the rim direction, so that the contact of the third contact plate 410 The outer wall of the rim is contacted by the first wedge block 414 and the contact block 412, so that the first wedge block 414 and the contact block 412 are contacted synchronously and move in the direction away from the rim. At this time, the thickness of the rim can be observed by observing the scale on the scale bar 47. The above is an inclined rim. If it is an arc-shaped rim, the extension of the output shaft of the second electric push rod 413 will make the second contact plate 411 and the upper part of the third contact plate 410 contact the rim, and the lower part cannot and there is still a gap between the rim. At this time, the contact block 412 has not moved, so it is judged that the shape of the secondary rim is a bracket-shaped arc. The contact block 412 and the hinged plate 61 are adjusted to a suitable distance from the rim by the U-shaped telescopic frame 7, and then the contact block 412 is contacted to drive the hinged plate 61 to move, thereby driving the L-shaped limit frame 614 and the L-shaped slide The movable plate 612 and the driving motor 65 move synchronously with the first bevel gear 610, so that the first bevel gear 610 and the second bevel gear 611 are disengaged. If it is an arc-shaped rim, at this time, since the end of the output shaft of the second electric push rod 413 is located at the upper half of the second contact plate 411, when the third contact plate 410 contacts the surface of the arc-shaped rim, the lower half of the third contact plate 410 cannot contact the rim, so that the contact block 412 cannot move, so that the driving motor 65 is reset by the action of the mounting spring 66, so that the first bevel gear 610 and the second bevel gear 611 are engaged, the output shaft of the driving motor 65 rotates to drive the first bevel gear 610 to rotate, the first bevel gear 610 drives the second bevel gear 611 to rotate, and the rotation of the second bevel gear 611 drives the reciprocating The screw rod 63 rotates, and the reciprocating screw rod 63 rotates to drive the long plate 613 to move. The movement of the long plate 613 drives the U-shaped telescopic frame 7 to extend and retract up and down, and the U-shaped telescopic frame 7 drives the whole to move, so as to measure the arc rim as a whole. Then, the second wedge block 51 moves up to drive the plug-in shaft 510 and the connecting plate 56 to move up synchronously, and the connecting plate 56 moves up to drive the limiting shaft 511 to move synchronously. The limiting shaft 511 limits the pawl 512, so that the ratchet 515 can only rotate in one direction, and the one-way gear 54 can only rotate in one direction through the fixation of the connecting shaft 57, so that the one-way rack 55 can only move toward the rim direction under the action of the one-way gear 54, and the thickness of the thickest position of the rim is measured, which is convenient for the subsequent installation of the tire.
