Description

Technical Field

[0001] The invention relates to the technical field of conveying wheels, in particular to an angle-adjustable Mecanum conveying 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 an angle-adjustable Mecanum conveyor wheel, which can adjust the inclination angle of the roller on the wheel surface only by relatively rotating the mounting plate, thereby changing the conveying direction of the roller and ensuring the stability of the product structure.

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

[0007] An angle-adjustable Mecanum conveyor wheel 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 onto 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 pushing into 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.

[0008] Compared with the prior art, the technical effect of the present invention is that the Mecanum conveyor wheel of the present invention can adjust the roller angle only by relatively rotating the first mounting plate and the second mounting plate, without adjusting other components, and can ensure the structural reliability of the Mecanum wheel, and the roller angle adjustment range can be at least between +45° and -45°.

[0009] As a further improvement of the above technical solution, the boss is provided with scale lines; and the second mounting plate is provided with an observation hole for displaying the scale lines.

[0010] The technical effect of the above improvement is that when the second mounting plate is rotated, the observation hole and the scale line move relative to each other, so that the correct scale position can be displayed through the observation hole, which is convenient for the user to know the rotation angle at this time, thereby better confirming the tilt angle of the roller on the Mecanum wheel.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] The technical effect of the above improvement is that the isomorphic fourth spring and 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 the position.

[0017] As a further improvement of the above technical solution, the first mounting plate is fixedly connected to the base shaft.

[0018] 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.

[0019] As a further improvement of the above technical solution, the boss is sleeved on the installation shaft and can move axially; a screw hole is provided at the end of the base shaft, and a screw passes through the screw hole from the other end of the base shaft and then abuts against the boss.

[0020] 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.

[0021] 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 and a first mounting disk; a screw is provided on the first mounting disk; the screw is threadedly connected to the end face of the base shaft; the first mounting disk presses the third spring against the end face of the base shaft.

[0022] The technical effect of the above improvement is: by rotating the screw, the third spring can be shortened and extended, so that the axial position of the first mounting plate on the base shaft can be adjusted, thereby adjusting the distance between the first mounting plate and the second mounting plate, thereby further expanding the adjustment range of the roller angle.

[0023] As a further improvement of the above technical solution, the boss is sleeved on the mounting shaft and can move axially; an annular groove is provided on the end of the base shaft opposite to the mounting shaft; a through hole is provided on the bottom surface of the annular groove, and a support shaft is provided in the through hole; a nut ring is threadedly connected in the annular groove, and the nut ring presses the support shaft so that the other end of the support shaft rests against the boss.

[0024] The technical effect of the above improvement is: the positions of multiple support shafts can be adjusted simultaneously by only rotating the nut ring, thereby adjusting the axial position of the boss on the mounting shaft, 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.

[0025] 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.

[0026] The technical effect of the above improvement is: the positions of multiple support shafts can be adjusted simultaneously by only rotating the nut ring, thereby adjusting the axial position of the boss on the mounting shaft, 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 threadedly connected to the mounting head, making it more convenient for the operator to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. 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.

[0043] Embodiment 1:

[0044] See also Figures 1 to 7 , an angle-adjustable Mecanum conveyor wheel, comprising a base shaft 1, a first mounting plate 2 is arranged at one end of the base shaft 1, a mounting shaft 4 is arranged at the other end, a boss 3 is arranged at the connection between the mounting shaft 4 and the base shaft 1; a second mounting plate 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 plate 5 against the end surface of the boss 3 through the second spring 11; a strip groove 10 is arranged on the outer wall of the mounting shaft 4; an elastically retractable push rod 9 for supporting in the strip groove 10 is arranged on the inner wall of the mounting hole of the second mounting plate 5; embedding holes are distributed in annular shapes on the opposite end surfaces of the first mounting plate 2 and the second mounting plate 5, the ball heads of the ball head rods 6 are embedded in the holes, and the rod bodies are movable; a rotatable roller 7 is installed between the rod bodies of the corresponding ball head rods 6.

[0045] 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.

[0046] Specifically, Figure 5 As shown, 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 pointed cone, 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;

[0047] Specifically, Figure 2As 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.

[0048] like Figure 2-4 As shown, as a further optimization of the above embodiment, the boss 3 is provided with scale lines 31 ; and the second mounting plate 5 is provided with an observation hole 13 for displaying the scale lines 31 .

[0049] Specifically, the scale line 31 is in the shape of an arc or a circle; specific degrees can be marked above the scale line 31, such as several key degrees such as: 0° refers to the roller being parallel to the axis of the Mecanum wheel; +45° refers to the roller being inclined at a positive angle of 45° to the axis of the Mecanum wheel; -45° refers to the roller being inclined at a negative angle of 45° to the axis of the Mecanum wheel; when the second mounting plate 5 rotates, the observation hole 13 can display the scale of the corresponding position, so that the operator can know the inclination angle of the roller at this time.

[0050] like Figure 5 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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 .

[0055] 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.

[0056] As a further optimization of the above embodiment, the first mounting plate 2 is fixedly connected to the base shaft 1 .

[0057] 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.

[0058] The working principle of the above embodiment is as follows:

[0059] The second mounting disk 5 is rotated so that the second mounting disk 5 and the first mounting disk 2 rotate relative to each other. During the rotation, the push rod 9 telescopes and moves between the strip grooves 10. When the second mounting disk 5 is rotated 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 ball head rods 6 at both ends of the same roller 7 change, causing the inclination angle of the roller 7 to change, 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 adaptive position as the spacing changes.

[0060] The compression amount of the second spring 11 can be adjusted by adjusting the axial position of the fixing ring 12 , thereby achieving the adjustment of the structural stability of the second mounting plate 5 .

[0061] 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°.

[0062] 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.

[0063] Embodiment 2:

[0064] like Figure 8-9As shown, as a further optimization of the above embodiment, the boss 3 is sleeved on the mounting shaft 4 and can move axially; a screw hole is opened at the end of the base shaft 1, and the screw 17 passes through the screw hole from the other end of the base shaft 1 and then abuts against the boss 3.

[0065] Specifically, the boss 3 is in the shape of a disk and is sleeved on the mounting shaft 4. Through screw holes are provided at both ends of the base shaft 1. The screw 17 is in the shape of a long screw and is threadedly connected in the screw hole, with the end thereof abutting against the boss 3. The other end of the boss 3 is abutted by the second spring 11. A countersunk hole is provided at the end of the screw hole so that the screw head of the screw 17 sinks into the countersunk hole. By rotating each screw 17, the boss 3 can be moved axially on the mounting shaft 4, and the second spring 11 expands and contracts accordingly. The movement of the boss 3 will change the spacing between the first mounting plate 2 and the second mounting plate 5, thereby adapting to the spacing change caused by the inclination of the roller.

[0066] The working principle of the above embodiment is as follows:

[0067] 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 screw 17 is rotated, the position of the screw 17 in the screw hole of the base shaft 1 changes, so that the boss 3 moves along the axial direction of the mounting shaft 4. When the boss 3 moves toward the base shaft, the distance between the first mounting plate 2 and the second mounting plate 5 is reduced. When the boss 3 moves away from the base shaft, the distance between the first mounting plate 2 and the second mounting plate 5 is expanded. The change in the distance between the first mounting plate 2 and the second mounting plate 5 can adapt to the distance change 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 distance 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 of the roller larger, thereby increasing the angle adjustment range of the Mecanum wheel roller.

[0068] Embodiment three:

[0069] 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 and a first mounting disk 2; the first mounting disk 2 is provided with a screw 17; the screw 17 is threadedly connected to the end face of the base shaft 1; the first mounting disk 2 presses the third spring 23 against the end face of the base shaft 1.

[0070] Specifically, four or six screws 17 are arranged in a ring shape. By rotating the screws 17 to the same depth, the first mounting plate 2 can be adjusted to move along the mounting head 21, so that the distance between the first mounting plate 2 and the second mounting plate 5 changes, thereby adapting to the distance change caused by the inclination of the roller.

[0071] The working principle of the above embodiment is as follows:

[0072] 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 screw 17 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.

[0073] Embodiment 4:

[0074] like Figure 11-12 As shown, as a further optimization of the above embodiment, the boss 3 is sleeved on the mounting shaft 4 and can move axially; an annular groove 19 is provided on the end of the base shaft 1 opposite to the mounting shaft 4; a through hole is provided on the bottom surface of the annular groove 19, and a support shaft 18 is provided in the through hole; a nut ring 20 is threadedly connected in the annular groove 19, and the nut ring 20 presses the support shaft 18 so that the other end of the support shaft 18 is against the boss 3.

[0075] Specifically, the support shaft 18 is a smooth shaft, one end of which is in contact with or connected to the boss 3, and the other end is pressed by the nut ring 20, so that the support shaft 18 and the second mounting plate 5 clamp the boss 3 together; the position of the nut ring 20 in the annular groove 19 can be adjusted by rotating the nut ring 20, thereby adjusting the expansion and contraction of the support shaft 18, thereby adjusting the moving position of the boss 3. Since the annular groove 19 is directly embedded in the end surface of the mounting shaft 4, the nut ring 20 is hidden in the annular groove 19 and does not occupy space.

[0076] The working principle of the above embodiment is as follows:

[0077] 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 depth of the nut ring 20 in the annular groove 19 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, 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.

[0078] Embodiment five:

[0079] like Figure 13-14 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.

[0080] Specifically, 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 plate 5 to move axially to adjust the position, so that the spacing between the first mounting plate 2 and the second mounting plate 5 changes, thereby adapting to the spacing change caused by the inclination of the roller.

[0081] The working principle of the above embodiment is as follows:

[0082] 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.
