Description

Technical Field

[0001] The invention relates to the technical field of conveying wheels, in particular to a Mecanum wheel capable of synchronously adjusting an angle and a conveying device formed by the wheel. Background Art

[0002] Mecanum wheels can realize not only forward and backward conveying, but also oblique conveying. Therefore, conveyor tables made of Mecanum wheels are widely used in flat plate conveying.

[0003] The wheel surface of the Mecanum wheel is equipped with rollers that are set at an inclined angle to the rotation axis of the wheel. When the plate moves on the Mecanum wheel, it can move along the rotation direction of the Mecanum wheel and the rotation direction of the rollers on the wheel surface.

[0004] The rollers on the existing Mecanum wheel are fixedly installed, so when the Mecanum wheel is used as a conveyor, the conveying direction of the conveyor is basically fixed and cannot be adjusted. This results in some flat products being restricted when being conveyed through the Mecanum wheel conveyor. Summary of the invention

[0005] In view of the above problems, the present invention provides a Mecanum wheel with synchronously adjustable angles. Only one adjusting rod is needed to simultaneously control multiple coaxially mounted Mecanum wheels to synchronously adjust the inclination angles of their rollers, thereby greatly improving its application range in automatic control of conveying direction platforms.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A Mecanum wheel capable of synchronously adjusting an angle comprises a base shaft; a first mounting plate is arranged at one end of the base shaft, a mounting shaft is arranged at the other end, a boss is arranged at the connection between the mounting shaft and the base shaft; a second mounting plate, a second spring and a fixing ring are sleeved on the mounting shaft; the fixing ring presses the second mounting plate against the end surface of the boss through the second spring; a strip groove is arranged on the outer wall of the mounting shaft; an elastically retractable push rod for supporting in the strip groove is arranged on the inner wall of the mounting hole of the second mounting plate; embedding holes are distributed in an annular manner on the opposite end surfaces of the first mounting plate and the second mounting plate, the ball head of the ball head rod is embedded in the hole, and the rod body is movable; a rotatable roller is installed between the rod bodies of the corresponding ball head rods; an adjustment hole for installing an adjustment rod is opened on the second mounting plate; an arc hole for sliding the adjustment rod is opened on the first mounting plate.

[0008] Compared with the prior art, the technical effect of the Mecanum wheel of the present invention is as follows: the Mecanum wheel of the present invention that can synchronously adjust the angle of the roller can be adjusted by only rotating the first mounting plate and the second mounting plate relative to each other, without adjusting other components, and can ensure the structural reliability of the Mecanum wheel. At the same time, a single adjustment rod can be used to simultaneously control multiple coaxially mounted Mecanum wheels to synchronously adjust the inclination angle of their rollers, thereby greatly improving its application range in the automatic control of the conveying direction platform.

[0009] As a further improvement of the above technical solution, a mounting groove is provided on the second mounting plate; a radially movable push rod and a first spring for supporting the push rod are provided in the mounting groove; a conical head is provided at the front end of the push rod; and the conical head extends from the inner wall of the mounting hole of the second mounting plate.

[0010] The technical effect of the above improvement is: when the second mounting disk is rotated, the conical head of the push rod is squeezed with the strip groove, so that the push rod automatically retracts. When the second mounting disk is rotated to a predetermined position, the push rod automatically extends again so that the conical head is stuck between the strip grooves, thereby realizing the rotation angle positioning of the second mounting disk, and also enabling the second mounting disk to realize axial movement while the rotation angle positioning moves, thereby adapting to the change in the spacing between the first mounting disk and the second mounting disk caused by the change in the roller angle.

[0011] As a further improvement of the above technical solution, the roller comprises a roller body, the roller body is sleeved on a core shaft, and core shaft holes for inserting the ball head rod are arranged at both ends of the core shaft.

[0012] The technical effect of the above improvement is: the roller rotates on the core shaft, and the core shaft can be stably installed between the two ball head rods. When the inclination angle of the roller changes, the ball head rod automatically adjusts the swing angle to adapt, while ensuring the installation stability of the roller.

[0013] As a further improvement of the above technical solution, a fourth spring and a gasket are arranged in one of the core shaft holes; the gasket is located between the ball head rod and the fourth spring.

[0014] The technical effect of the above improvement is that the fourth spring and the gasket can ensure the installation stability of the core shaft when the ball head rod is moved axially in the core shaft hole to adjust its position.

[0015] As a further improvement of the above technical solution, the first mounting plate is fixedly connected to the base shaft.

[0016] The technical effect of the above improvement is that after the first mounting disk is fixedly connected to the base shaft, when the second mounting disk rotates on the base shaft, the positions of the first mounting disk and the second mounting disk move relative to each other, thereby achieving adjustment of the roller angle.

[0017] As a further improvement of the above technical solution, the boss is sleeved on the mounting shaft and can move axially; on the base shaft, an outwardly protruding mounting head is provided at the end opposite to the mounting shaft; a nut ring is provided on the mounting head; a through hole is provided on the end face of the base shaft, and a support shaft is provided in the through hole; the nut ring presses the support shaft so that the other end of the support shaft rests against the boss.

[0018] The technical effect of the above improvement is: the position of the boss on the mounting shaft can be adjusted by rotating the screw, so that the distance between the first mounting plate and the second mounting plate can be adjusted. When the distance between the first mounting plate and the second mounting plate is reduced, the adjustment range of the roller angle can be further expanded.

[0019] As a further improvement of the above technical solution, the boss is fixedly connected to the base shaft; on the base shaft, an outwardly protruding mounting head is provided at the end opposite to the mounting shaft; the mounting head is covered with a third spring, a first mounting plate, and a nut ring; a pin is provided on the first mounting plate; the pin is inserted into a movable hole on the end face of the base shaft; the nut ring presses the first mounting plate and the third spring onto the mounting head.

[0020] The technical effect of the above improvement is: the axial position of the first mounting disk on the mounting head can be adjusted simultaneously by rotating the nut ring, thereby adjusting the distance between the first mounting disk and the second mounting disk, thereby further expanding the adjustment range of the roller angle. At the same time, the nut ring is located in the annular groove and does not take up more space.

[0021] Another object of the present invention is to provide a conveying device composed of a Mecanum wheel with synchronously adjustable angle, comprising the Mecanum wheels installed on a rotating shaft at intervals, and an adjustment rod arranged parallel to the rotating shaft; the adjustment rod is arranged through an adjustment hole and an arc hole of the Mecanum wheel on the corresponding rotating shaft; the end of the adjustment rod is connected to an adjustment sleeve; the adjustment sleeve is sleeved on the rotating shaft; and the adjustment sleeve is connected to a driving mechanism for driving it to rotate.

[0022] Compared with the prior art, the technical effect of the conveying device of the present invention is that by rotating the adjusting rod, all the second mounting disks on the same rotating shaft can be simultaneously controlled to rotate relative to the first mounting disk through the adjusting rod, thereby realizing synchronous adjustment of the roller inclination angles of all Mecanum wheels on the same rotating shaft.

[0023] As a further improvement of the above technical solution, the driving mechanism includes a gear coaxially arranged on the adjusting sleeve, and a rack that can be raised and lowered and is used to mesh with the gear is provided below the rotating shaft.

[0024] The technical effect of the above improvement is that the synchronous adjustment of the roller inclination angles of all Mecanum wheels on multiple rotating shafts can be controlled by lifting and lowering a rack rod, thereby controlling the conveying direction of the entire platform using Mecanum wheels for conveying. When the rack rod rises and meshes with the gear, the rotating shaft rotates a certain angle, which can control the relative rotation of the first mounting plate and the second mounting plate, thereby realizing the synchronous adjustment of the roller inclination angles of all Mecanum wheels.

[0025] As a further improvement of the above technical solution, the rack is slidably arranged in the guide rail groove; the lower end of the guide rail groove is connected to the lifting mechanism; and the end of the rack is connected to the telescopic mechanism.

[0026] The technical effect of the above improvement is: the lifting mechanism controls the guide rail groove to rise, so that the rack rod rises and engages with the gear, and the telescopic mechanism controls the rack to move in the horizontal plane, thereby driving the gear to rotate a certain angle, so that the first mounting plate and the second mounting plate can be controlled to rotate relative to each other, thereby realizing the synchronous adjustment of the inclination angle of the rollers of all Mecanum wheels.

The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0044] Embodiment 1:

[0045] like Figure 1-7As shown, a Mecanum wheel with synchronously adjustable angle comprises a base shaft 1; a first mounting disk 2 is provided at one end of the base shaft 1, and a mounting shaft 4 is provided at the other end, and a boss 3 is provided at the connection between the mounting shaft 4 and the base shaft 1; a second mounting disk 5, a second spring 11, and a fixing ring 12 are sleeved on the mounting shaft 4; the fixing ring 12 presses the second mounting disk 5 against the end surface of the boss 3 through the second spring 11; a strip groove 10 is provided on the outer wall of the mounting shaft 4; an elastically retractable push rod 9 for supporting in the strip groove 10 is provided on the inner wall of the mounting hole of the second mounting disk 5; embedding holes are distributed in annular shape on the opposite end surfaces of the first mounting disk 2 and the second mounting disk 5, and the ball head of the ball head rod 6 is embedded in the hole, and the rod body is movable; a rotatable roller 7 is installed between the rod bodies of the corresponding ball head rods 6; an adjustment hole 13 for installing an adjustment rod 24 is opened on the second mounting disk 5; an arc hole 27 for sliding the adjustment rod 24 is opened on the first mounting disk 2.

[0046] Specifically, the base shaft 1 is shaft-shaped with an axial hole in the center; the first mounting disk 2 and the second mounting disk 5 are both disc-shaped with the same diameter; the boss 3 is disc-shaped, and the diameter of the boss 3 is smaller than that of the second mounting disk 5; the fixing ring 12 can be a nut, and a tightening screw hole is provided on the side wall of the fixing ring 12.

[0047] Specifically, the strip groove 10 is arranged along the axial direction of the installation shaft 4, and the strip groove 10 is distributed in an annular shape on the outer wall of the installation shaft 4; the strip groove 10 is generally a groove opened on the outer wall of the installation shaft 4, and can also be a groove formed between the protruding racks on the outer wall of the installation shaft 4; the end of the push rod 9 is conical or triangular cone-shaped, and is stuck in the strip groove 10; the denser the strip grooves 10 are, the higher the continuity of the angle adjustment of the roller;

[0048] Specifically, Figure 2 As shown, the embedding hole is spherical and matches the ball head of the ball head rod 6; the embedding hole is composed of a mounting plate and a cover plate 14; the cover plate 14 is annular and is mounted on the end faces of the first mounting plate 2 and the second mounting plate 5 by bolts; the end face edge of the mounting plate is provided with a ring-shaped hole for the rod body part of the ball head rod 6 to pass through; the other end face of the mounting plate is provided with an arc groove connected to the hole; the arc groove on the cover plate 14 matches with the arc groove on the mounting plate to form a spherical cavity; the ball head of the ball head rod 6 is embedded in the spherical cavity, and the rod body is extended and movable.

[0049] like Figure 2 , 4 As shown, as a further optimization of the above embodiment, a mounting groove 51 is provided on the second mounting plate 5; a radially movable push rod 9 and a first spring 8 for supporting the push rod 9 are provided in the mounting groove 51; a conical head is provided at the front end of the push rod 9; and the conical head extends from the inner wall of the mounting hole of the second mounting plate 5.

[0050] Specifically, the mounting groove 51 is opened along the radial direction of the second mounting disk 5, the push rod 9 can be square-shaped, and the end is provided with a rod-shaped conical head; the push rod 9 moves radially in the mounting groove 51, and the first spring 8 supports the tail end of the push rod 9; the end of the mounting groove 51 is connected to the inner wall of the inner hole of the second mounting disk 5, so that the conical head can extend into the inner wall of the mounting hole, thereby supporting the strip groove 10.

[0051] like Figure 7 As shown, as a further optimization of the above embodiment, the roller 7 includes a roller body 71, and the roller body 71 is sleeved on a core shaft 72. Both ends of the core shaft 72 are provided with core shaft holes 73 for inserting the ball head rod 6.

[0052] Specifically, the roller 71 is rotatably mounted on the core shaft 72 and cannot move axially; both ends of the core shaft 72 are mounted on the rod body of the ball head rod 6; or the roller 71 is fixedly connected to the core shaft 72, and the core shaft 72 can rotate between the ball head rod 6.

[0053] like Figure 7 As shown, as a further optimization of the above embodiment, a fourth spring 74 and a gasket 75 are disposed in one of the core shaft holes 73 ; the gasket 75 is located between the ball head rod 6 and the fourth spring 74 .

[0054] Specifically, a fourth spring 74 is installed in the core shaft hole 73, and then a gasket 75 is placed therein, and then the ball head rod 6 is inserted; in this way, even if the ball head rod 6 moves axially in the core shaft hole, the core shaft 72 can be ensured to remain stable in the axial direction.

[0055] like Figure 2 As shown, as a further optimization of the above embodiment, the first mounting plate 2 is fixedly connected to the base shaft 1 .

[0056] Specifically, the first mounting plate 2 and the base shaft 1 are an integrated structure, or the first mounting plate 2 is fixedly mounted on the base shaft 1 by bolts.

[0057] The working principle of the above embodiment is as follows:

[0058] The second mounting disk 5 and the first mounting disk 2 are driven to rotate relative to each other by inserting the adjusting rod into the adjusting hole. During the rotation, the push rod 9 telescopes and moves between the strip grooves 10. When the second mounting disk 5 rotates to a predetermined position, the push rod 9 is inserted into the corresponding strip groove 10, so that the second mounting disk 5 and the mounting shaft 4 do not rotate. At this time, the positions of the spherical rods 6 at both ends of the same roller 7 change, resulting in a change in the inclination angle of the roller 7, resulting in a change in the spacing between the first mounting disk 2 and the second mounting disk 5. However, since the second mounting disk 5 is pressed against the boss 3 by the second spring 11, even if the spacing between the second mounting disk 5 and the first mounting disk 2 changes, the second mounting disk 5 can always remain in an adapted position as the spacing changes.

[0059] The compression amount of the second spring 11 can be adjusted by adjusting the axial position of the fixing ring 12 , thereby achieving adjustment of the structural stability of the second mounting plate 5 .

[0060] Since the second mounting plate 5 and the first mounting plate 2 can be relatively rotated to adjust the position and be positioned, the inclination angle of the roller can be adjusted accordingly, thereby achieving an adjustment from at least -45° to +45°.

[0061] Since the roller angle of the Mecanum conveyor wheel of the present invention is adjustable, the user can adjust the conveying direction of the Mecanum conveyor wheel without replacing other wheels, so the application range is wider and the use is more flexible and convenient.

[0062] Embodiment 2:

[0063] like Figure 8 As shown, as a further optimization of the above embodiment, the boss 3 is sleeved on the mounting shaft 4 and can move axially; the base shaft 1 is provided with an outwardly protruding mounting head 21 at the end opposite to the mounting shaft 4; a nut ring 20 is provided on the mounting head 21; a through hole is provided on the end face of the base shaft 1, and a support shaft 18 is provided in the through hole; the nut ring 20 presses the support shaft 18 so that the other end of the support shaft 18 rests against the boss 3.

[0064] Specifically, the boss 3 is in a circular ring shape and is sleeved on the mounting shaft 4; the support shaft 18 is a smooth shaft, one end of which is in contact with or connected to the boss 3, and the outer wall of the mounting head 21 is provided with a thread, which cooperates with the nut ring 20; the nut ring 20 is threadedly installed on the mounting head 21; by rotating the nut ring 20, the support shaft 18 can be pushed to move in the through hole, so that the support shaft 18 pushes the boss 3 to move, thereby driving the second mounting disk 5 to move axially to adjust the position, so that the spacing between the first mounting disk 2 and the second mounting disk 5 changes, thereby adapting to the spacing change caused by the inclination of the roller.

[0065] The working principle of the above embodiment is as follows:

[0066] The second mounting plate 5 can be rotated and positioned on the mounting shaft 4 to adjust the inclination angle of the roller 7. At the same time, in order to achieve more flexible adjustment, when the nut ring 20 is rotated, the axial position of the nut ring 20 on the mounting head 21 changes, so that all the support shafts 18 are telescopically moved, so that the boss 3 moves axially, so that the spacing between the first mounting plate 2 and the second mounting plate 5 changes, which can adapt to the spacing changes caused by the different inclination angles of the roller 7, so as to ensure the rotational stability of the roller after the inclination angle changes. Since the spacing between the first mounting plate 2 and the second mounting plate 5 can be actively adjusted, the rotational stability of the roller after the inclination angle changes can be ensured; and it is more convenient for users to replace the roller. For example, replacing a roller with a smaller diameter can make the inclination angle range of the roller larger, thereby improving the angle adjustment range of the Mecanum wheel roller.

[0067] Embodiment three:

[0068] like Fig.10 As shown, as a further optimization of the above embodiment, the boss 3 is fixedly connected to the base shaft 1; the base shaft 1 is provided with an outwardly protruding mounting head 21 at the end opposite to the mounting shaft 4; the mounting head 21 is sleeved with a third spring 23, a first mounting disk 2, and a nut ring 20; the first mounting disk 2 is provided with a pin 17; the pin 17 is inserted into a movable hole 22 on the end face of the base shaft 1; the nut ring 20 presses and fixes the first mounting disk 2 and the third spring 23 on the mounting head 21.

[0069] Specifically, a pin shaft 17 is installed in a ring shape on the first mounting disk 2, and a corresponding number of movable holes 22 are provided on the end face of the base shaft 1; the pin shaft 17 is inserted into the movable hole 22, thereby limiting the first mounting disk 2 to move only in the axial direction; when the nut ring 20 is rotated, the nut ring 20 can drive the first mounting disk 2 to move axially on the mounting head 21; at the same time, it cooperates with the third spring 23 to ensure that the installation of the first mounting disk 2 remains stable.

[0070] The working principle of the above embodiment is as follows:

[0071] When the nut ring 20 is rotated, the position of the screw 17 in the screw hole of the base shaft 1 changes, so that the first mounting plate 2 moves along the axial direction of the mounting head 21, so that the spacing between the first mounting plate 2 and the second mounting plate 5 changes, which can adapt to the spacing changes caused by the different inclination angles of the roller 7, thereby ensuring the rotational stability of the roller after the inclination angle changes. Since the spacing between the first mounting plate 2 and the second mounting plate 5 can be actively adjusted, the rotational stability of the roller after the inclination angle changes can be ensured; and it is more convenient for users to replace the roller. For example, replacing a roller with a smaller diameter can make the inclination angle range of the roller larger, thereby increasing the angle adjustment range of the Mecanum wheel roller.

[0072] Embodiment 4:

[0073] like Figure 11-15 As shown, a conveying device composed of a Mecanum wheel capable of synchronously adjusting an angle includes the Mecanum wheel installed on a rotating shaft 25 at a spacing, and an adjustment rod 24 arranged parallel to the rotating shaft 25; the adjustment rod 24 is arranged through the adjustment hole 13 and the arc hole 27 of the Mecanum wheel on the corresponding rotating shaft 25; the end of the adjustment rod 24 is connected to an adjustment sleeve 26; the adjustment sleeve 26 is sleeved on the rotating shaft 25; and the adjustment sleeve 26 is connected to a driving mechanism for driving it to rotate.

[0074] Specifically, the Mecanum wheel is installed on the rotating shaft 25 through the shaft hole 15; the rotating shaft 25 is driven to rotate by a motor; the adjusting rod 24 is arranged through the adjusting hole 13, and the adjusting rod 24 can rotate around the rotating shaft 25, thereby driving the second mounting plate 5 to rotate, and the adjusting rod 24 moves in the arc hole 27; the arc length of the arc hole 27 limits the range of movement of the adjusting rod 24; the adjusting sleeve 26 is clearance-matched with the rotating shaft 25, so that the adjusting sleeve 26 can rotate on the rotating shaft 25; the adjusting sleeve 26 can be driven to rotate by the auxiliary motor installed on the rotating shaft 25.

[0075] like Figure 12-13 As shown, as a further optimization of the above embodiment, the driving mechanism includes a gear 30 coaxially arranged on the adjustment sleeve 26, and a rack 28 that can be raised and lowered and is used to mesh with the gear 30 is provided below the rotating shaft 25.

[0076] Specifically, a gear 30 is provided on the outer wall of the adjustment sleeve 26; the rack 28 is located below the end of the rotating shaft 25, and is driven up and down by the lifting mechanism 29; when the rack 28 rises and engages with the gear 30, the adjustment sleeve 26 cannot move synchronously with the rotating shaft 25; at this time, the rotating shaft 25 is driven by the servo motor to rotate a predetermined angle, and the rotating shaft 25 drives the base shaft 1 and the first mounting disk 2 to rotate. At this time, the second mounting disk 5 is restricted by the adjusting rod 24 and cannot rotate, thereby realizing the relative rotation of the first mounting disk 2 and the second mounting disk 5, thereby adjusting the inclination angle of the roller 7.

[0077] As a further optimization of the above embodiment, the rack 28 is slidably disposed in the guide rail groove 32 ; the lower end of the guide rail groove 32 is connected to the lifting mechanism 29 ; and the end of the rack 28 is connected to the telescopic mechanism 31 .

[0078] Specifically, a gear 30 is provided on the outer wall of the adjusting sleeve 26; the rack 28 is located below the end of the rotating shaft 25, and the rack 28 is staggered with the rotating shaft and is located below the rotating shaft 25; the rack 28 is installed in the guide groove 32; it can slide in the guide groove 32 along the length direction; the guide groove 32 is driven up and down by the lifting mechanism 29, and the lifting mechanism 29 can be a cylinder cylinder or an electric push rod; one end of the rack 28 is connected to the telescopic mechanism 31, and the telescopic mechanism 31 can be a cylinder cylinder or an electric push rod; the lifting mechanism 29 drives the guide groove 32 to rise, so that the rack 28 is engaged with the gear 30, and then the telescopic mechanism 31 drives the rack 28 to move along the length direction, and the rack 28 drives the gear 30 to rotate, thereby driving the adjusting sleeve 26 to rotate, and the adjusting sleeve 26 drives the adjusting rod 24 to rotate around the rotating shaft 25, thereby driving the second mounting plate 5 to rotate, so that the first mounting plate 2 and the second mounting plate 5 rotate relative to each other, thereby adjusting the inclination angle of the roller 7.

[0079] Since the Mecanum wheel on a rotating shaft can be adjusted by an adjusting rod, and the adjusting rod is connected to the adjusting sleeve; a rack can drive the adjusting sleeves on multiple rotating shafts to rotate, so the roller angle adjustment of the Mecanum wheel of the entire conveying table can be driven by a rack.
