Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to a paving machine. Background Technology

[0002] With the development of power tool technology, tile laying machines are increasingly favored by consumers due to their efficient tile laying.

[0003] In traditional technology, the paving machine has a vibration motor for vibration and a suction cup located at the bottom of the machine. The suction cup is usually activated by a trigger below the handle.

[0004] However, in the current vacuum suction cup structure, the motor-driven suction cup may become loose due to vibration during use, which leads to the failure of the vacuum suction cup and prevents the energy of the vibration motor from being transferred to the tile through the suction cup. Utility Model Content

[0005] Therefore, it is necessary to provide a paving machine to address the problem of suction cup failure caused by vibration.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In one embodiment, a tiling machine is provided, comprising: a housing; a suction cup disposed at a lower end of the housing; a first motor housed within the housing, the first motor having a first output shaft and an eccentric block fixedly connected to the output shaft; a second motor housed within the housing; a controller for controlling the rotation of the first motor and the second motor; and a transmission mechanism including a transmission component and a locking component, the transmission mechanism further including a second output shaft receiving a driving force from the second motor to drive the suction cup, the locking component restricting the second output shaft from applying a driving force to the motor.

[0008] Optionally, the transmission assembly includes a planetary gear set disposed between the second motor and the output shaft. The transmission assembly includes an internal gear ring, planetary gears, and a planet carrier. The internal gear ring is fixedly connected to the housing. A plurality of planetary gears mesh with the internal gear ring. A locating pin is disposed on the side of the planet carrier facing the planetary gears, and the plurality of planetary gears are correspondingly sleeved on the locating pin.

[0009] Optionally, the planetary carrier further includes a drive hole, in which the output shaft is at least partially inserted. The portion of the output shaft inserted in the drive hole is further provided with a force-bearing part, which is an axially extending plane. A drive part is radially protruding from the inner wall of the drive hole. The drive part is fan-shaped, and the two end faces of the drive part can selectively abut against the force-bearing part of the output shaft.

[0010] Optionally, the locking component is disposed between the transmission component and the output shaft, and the locking component receives power from the transmission component to drive the output shaft to rotate.

[0011] Optionally, the locking assembly includes a locking ring and a limiting member, the output shaft extends at least partially into the locking assembly, the portion of the output shaft extending into the locking assembly is provided with a limiting surface, and the limiting member is radially clamped between the limiting surface and the locking ring.

[0012] Optionally, the limiting surface and the limiting member are correspondingly provided, and multiple such limiting surfaces are configured.

[0013] Optionally, the limiting surface and the plane of the force-receiving part are coplanar.

[0014] Optionally, the suction cup is equipped with a pull rod, the pull rod is equipped with a threaded hole, the second output shaft is threadedly connected to the pull rod, the axial end face of the pull rod is also equipped with a limit hole, and the housing is equipped with a positioning pin on the side facing the suction cup, which is inserted into the limit hole, and the positioning pin restricts the rotation of the suction cup.

[0015] Optionally, an elastic element is also provided between the suction cup and the housing.

[0016] Optionally, the rotation axis of the first output shaft is perpendicular to the rotation axis of the second output shaft.

[0017] In this embodiment, the second motor transmits driving force to the output shaft through the transmission component to lift the suction cup, thereby creating a vacuum between the suction cup and the working surface. At the same time, the locking component restricts the output shaft from driving the second motor in the reverse direction, preventing the output shaft from rotating when the whole machine vibrates, which would cause the suction cup to fail.

[0032] See Figure 1 and Figure 2 Figure 1 shows a three-dimensional structural schematic diagram of a paving machine according to an embodiment of this application. Figure 2 A schematic diagram of the internal structure of a paving machine according to an embodiment of this application is shown. An embodiment of this application provides a paving machine 100, including a housing 1, a suction cup 2 disposed at the lower end of the housing 1, a first motor 3 housed within the housing 1, a second motor 4 housed within the housing 1, a controller 5 for controlling the rotation of the first motor 3 and the second motor 4, and a transmission mechanism 6 connecting the second motor 4 and the suction cup 2.

[0033] See Figures 3 to 6 The first motor 3 includes an eccentric block 32 and a first output shaft 31 extending along the axis of the first motor 3. The eccentric block 32 is sleeved on the first output shaft 31 and is fixedly connected to the first output shaft 31. The rotation of the first motor 3 drives the eccentric block 32 to rotate, and the eccentric block 32 outputs eccentric vibration.

[0034] In this embodiment, the transmission mechanism 6 includes a transmission component 61 and a locking component 62. The transmission mechanism 6 also includes a second output shaft 63. The second output shaft 63 receives the driving force of the second motor 4 through the transmission component 61, and the locking component 62 restricts the second output shaft 63 from applying the driving force to the second motor 4.

[0035] In this embodiment, the transmission assembly 61 includes a planetary gear set, which is disposed between the second motor 4 and the output shaft 63. Through the speed reduction transmission of the planetary gear set, the output speed of the second motor 4 on the second output shaft 63 can be reduced, facilitating better control of the movement of the second output shaft 63 on the suction cup 2.

[0036] Specifically, the transmission assembly 61 includes an internal gear ring 611, a planetary gear 612, and a planetary carrier 613. A second motor 4 is fitted with a motor gear 41, which drives the movement of the transmission assembly 61. The internal gear ring 611 is circumferentially fixed to the outer casing 1. Specifically, a positioning protrusion 6111 radially protrudes from the outer peripheral wall of the internal gear ring 611. The outer casing 1 is provided with a receiving cavity 11 that accommodates at least a portion of the transmission mechanism 6. The inner wall of the receiving cavity 11 is provided with a first positioning groove 111 that accommodates the positioning protrusion 6111. The positioning protrusion 6111 is disposed within the first positioning groove 111, restricting the rotation of the internal gear ring 611 relative to the outer casing 1. Multiple planetary gears 612 are provided and are evenly arranged circumferentially around the axis of the internal gear ring 611. Multiple planetary gears 612 mesh with the internal gear ring 611 and with the motor gear 41 respectively. Multiple locating pins 6131 are provided on the side of the planetary carrier 613 facing the planetary gears 612. The planetary gears 612 are sleeved on the locating pins 6131 to receive the driving force of the motor gear 41 and transmit it to the planetary carrier 613.

[0037] In this embodiment, the planetary carrier 613 further includes a drive hole 6132 that mates with the second output shaft 63. At least a portion of the second output shaft 63 is inserted into the drive hole 6132. The portion of the second output shaft 63 inserted into the drive hole 6132 is provided with a force-bearing portion 631. For ease of processing, the force-bearing portion 631 can be an axially extending plane. The inner wall of the drive hole 6132 has a radially protruding drive portion 6133. The projection of the drive portion 6133 along the axial direction of the planetary carrier 613 is fan-shaped. The two sides of the drive portion 6133 can selectively abut against the force-bearing portion 631 on the second output shaft 63, so that the planetary carrier 613 can selectively apply a clockwise or counterclockwise rotational driving force to the second output shaft 63.

[0038] In this embodiment, the locking component 62 is disposed between the transmission component 61 and the second output shaft 63. The locking component 62 receives power from the transmission component 61 and drives the rotation of the second output shaft 63. By transmitting the decelerated driving force to the second output shaft 63 through the locking component 62, the rotational parameters of the second output shaft 63 can be better controlled, such as the number of rotations.

[0039] See Figure 5 and Figure 6 The locking assembly 62 includes a locking ring 621 and a limiting member 622. At least a portion of the second output shaft 63 extends into the locking assembly 62 to receive the driving force applied by the locking assembly 62 to the second output shaft 63. Specifically, the locking ring 621 has an annular central hole 6211. The portion of the second output shaft 63 extending into the locking assembly 62 is provided with a limiting surface 632. The limiting member 622 is radially sandwiched between the limiting surface 632 and the central hole 6211. The limiting surface 632 is an axially extending plane, and the limiting member 622 can be a rolling element such as a ball or a pin. Preferably, the limiting member 622 is a pin, which has a large contact surface with the limiting surface 632 and the locking ring 621, allowing for more effective locking.

[0040] In this embodiment, in order to fix the locking ring 621 circumferentially on the outer shell 1, the outer peripheral wall of the locking ring 621 has a protrusion 6212 that protrudes radially, and the inner wall of the receiving cavity 11 is provided with a second positioning groove 112 to accommodate the protrusion 6212. The protrusion 6212 is disposed in the second positioning groove 112 to restrict the rotation of the locking ring 62 relative to the outer shell 1.

[0041] In this embodiment, multiple limiting surfaces 632 and multiple limiting members 622 are provided. The limiting surfaces 632 and the limiting members 622 correspond one-to-one and are evenly arranged along the axial and circumferential directions of the central hole 6211.

[0042] In this embodiment, the planes of the limiting surface 632 and the force-receiving part 631 are coplanar, and the plane of the force-receiving part 631 is positioned closer to the axial end than the limiting surface 632. This simplifies the manufacturing process and reduces costs.

[0043] In this embodiment, the transmission assembly 61 further includes a bearing 64 supporting the output shaft 63 and a first retaining ring 65 restricting the axial movement of the bearing 64. The bearing 64 is fixedly installed in the receiving cavity 11, and one end of the bearing 64 abuts against the outer shell 1, while the other end abuts against the first retaining ring 65.

[0044] The second output shaft 63 is sleeved in the central hole of the bearing 64, and a radially protruding annular rib 633 is located near the lower end face of the bearing 64, restricting the axial downward movement of the second output shaft 63. An annular groove 634 is positioned near the upper end face of the bearing 64, and the annular groove 634 engages with the second retaining spring 66, restricting the axial upward movement of the second output shaft 63. The second output shaft 63 is axially restricted by the bearing 64.

[0045] In this embodiment, the suction cup 2 is equipped with a pull rod 21. The end face of the pull rod 21 facing the second output shaft 63 has a threaded hole 211. The second output shaft 63 has a threaded portion 634 that is threadedly connected to the threaded hole 211. The pull rod 21 is threadedly connected to the second output shaft 63. A limiting hole 212 is also provided on the end face of the pull rod 21 facing the second output shaft 63. A positioning pin 12, which inserts into the limiting hole 212, is provided on the side of the housing 1 facing the pull rod 21. The positioning pin 12 restricts the relative rotation of the suction cup 2 relative to the second output shaft 63. At this time, the rotation of the second output shaft 63 can drive the axial movement of the pull rod 21.

[0046] It is understandable that when the suction cup 2 moves axially under the driving force of the second output shaft 63, within the axial range of motion of the suction cup 2, the threaded hole 211 also has a clearance space to avoid the second output shaft 63, and similarly, the limiting hole 212 also has a clearance space to avoid the positioning pin 12.

[0047] In this embodiment, an elastic element 7 is also disposed between the suction cup 2 and the outer shell 1. One end of the elastic element 7 abuts against the suction cup 2 and the other end abuts against the outer shell 1. The elastic element 7 has an elastic restoring force that drives the suction cup 2 away from the outer shell 1 and provides an auxiliary force when the suction cup 2 returns to a non-vacuum state.

[0048] In this embodiment, the rotation axis of the first output shaft 31 and the rotation axis of the second output shaft 63 are perpendicular. This avoids the vibration caused by the rotation of the eccentric block 32 fixed on the first output shaft 31 acting on the locking component 62, which provides a reliable locking function.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
