Technical Field

[0001] The present invention relates to the technical field of construction equipment, and in particular to a fastening assembly and construction equipment. Background Art

[0002] Construction equipment such as putty grinders, polishers, and cutters typically have a driver and an actuator. The driver drives the actuator to rotate to perform the work. During assembly, the output shaft of the driver is susceptible to shaking due to external forces, and auxiliary tools such as wrenches are often required to secure the actuator. However, this requirement hinders operational convenience. Summary of the Invention

[0003] The embodiments of the present invention provide a fastening assembly and construction equipment to improve the above-mentioned problems.

[0004] The embodiments of the present invention achieve the above-mentioned objectives through the following technical solutions.

[0005] In a first aspect, an embodiment of the present invention provides a fastening assembly for construction equipment, wherein the construction equipment includes a driving member and an actuator, wherein the driving member has an output shaft, and the actuator is mounted on the output shaft. The fastening assembly includes a first pressure member, a second pressure member, and an intermediate member, wherein the second pressure member includes an axially connected operating body and a fastening body, wherein the fastening body and the operating body are an integral structure, and the fastening body is rotatably inserted into the first pressure member, and the fastening body is used to be mounted on the output shaft and to press the first pressure member against the actuator. The intermediate member is disposed between the first pressure member and the operating body, and the second pressure member rotates relative to the first pressure member through the intermediate member to reduce the resistance of the second pressure member to rotation relative to the first pressure member.

[0006] In the fastening assembly of the embodiment of the present invention, the operating body of the second pressure piece is axially connected to the fastening body, and the fastening body is rotatably inserted into the first pressure piece. In the process of the fastening assembly fastening the actuator to the output shaft of the driving member, the fastening body is used to be installed on the output shaft of the driving member and press the first pressure piece against the actuator, so that the first pressure piece can press the actuator against the output shaft of the driving member, which helps the output shaft of the driving member not to shake easily under the friction of the actuator, and the intermediate piece is arranged between the first pressure piece and the operating body. The second pressure piece rotates relative to the first pressure piece through the intermediate piece to reduce the resistance of the second pressure piece to rotation relative to the first pressure piece, thereby helping the second pressure piece to be installed on the output shaft through the fastening body, so that the actuator can be fastened to the output shaft of the driving member without the use of auxiliary tools, which helps to improve the convenience of operation. In addition, since the fastening body and the operating body are an integrated structure, it helps to reduce the number of parts of the fastening assembly and improve the assembly efficiency of the fastening assembly.

[0007] In some embodiments, the fastening assembly further includes a sealing member, the sealing member is abutted between the operating body and the first pressing member, and the sealing member is disposed around the intermediate member.

[0008] In this embodiment, the sealing member can better seal the gap between the operating body and the first pressing member. The sealing member can be arranged around the middle member, thereby helping to reduce the impact of external dust and impurities on the movement of the middle member.

[0009] In some embodiments, the operating body includes a mounting boss, the fastening body is connected to the mounting boss, and the intermediate piece is sleeved on the fastening body and disposed on the mounting boss.

[0010] In this embodiment, the mounting boss facilitates the movement of the intermediate piece, and the intermediate piece always surrounds the fastener during movement without deviating from the position of the mounting boss, which helps to ensure the stability of the intermediate piece and thus helps to improve the stability of the second pressure piece in rotating relative to the first pressure piece.

[0011] In some embodiments, the operating body is provided with a seal installation groove, the seal installation groove is arranged around the installation boss, and the seal is installed in the seal installation groove.

[0012] In this embodiment, it helps to ensure that the position of the seal installed on the operating body is accurate, and it also helps to ensure that the position of the seal after being installed in the seal installation groove is not easily shifted due to external vibrations, so that the seal can better prevent external dust and impurities from falling on the middle part.

[0013] In some embodiments, the fastening assembly further includes a limiter mounted on the fastening body, the limiter being located on a side of the first pressing member away from the sealing member, and the limiter being used to limit the first pressing member from moving in a direction away from the sealing member.

[0014] In this embodiment, it helps to avoid the relative movement between the first pressure piece and the second pressure piece due to external vibration during the transportation of the fastening assembly, resulting in an excessively large distance between the first pressure piece and the operating body, so that the seal does not maintain contact with the operating body and the first pressure piece, and then causes the seal to be unable to block dust and impurities. It also helps to avoid the situation where the seal is not sealed in place due to deviation in the position of the seal.

[0015] In some embodiments, the fastening body is provided with a limiting member installation groove, and the limiting member is sleeved on the fastening body and located in the limiting member installation groove.

[0016] In this embodiment, it helps to ensure that the position of the limit member installed on the fastener is accurate, and it also helps to ensure that the position of the limit member after being installed in the limit member installation groove is not easily offset due to external vibrations, so that the limit member can better limit the movement of the first pressure member in the direction away from the sealing member.

[0017] In some embodiments, the first pressure member includes a pressure member mounting portion and a pressure ring. The pressure member mounting portion is rotatably mounted on the fastening member, and the limiter is configured to limit movement of the pressure member mounting portion in a direction away from the sealing member. The pressure ring is connected to a surface of the pressure member mounting portion facing away from the sealing member, and the limiter is located within a cavity enclosed by the pressure ring.

[0018] In this embodiment, the limiting member does not protrude outside the cavity surrounded by the pressure ring while limiting the movement of the first pressure member, thereby helping to ensure that the fastening assembly presses the actuator to the driving member through the pressure ring.

[0019] In some embodiments, the operating body is provided with a hand-held matching portion, and the hand-held matching portion is located on the outer peripheral surface of the operating body.

[0020] In this embodiment, it helps to avoid disposing the hand-held matching portion at one axial end of the operating body, thereby helping to prevent the hand-held matching portion from protruding along the axial direction of the operating body and affecting the working object.

[0021] In some embodiments, the intermediate member includes a bracket and a plurality of rotating bodies, the plurality of rotating bodies are arranged around the fastening body, each rotating body is rotatably mounted on the bracket, and the second pressing member rotates relative to the first pressing member through the rotating bodies.

[0022] In this embodiment, the plurality of rotating bodies helps to improve the smoothness of the relative rotation between the first pressing member and the second pressing member.

[0023] In a second aspect, an embodiment of the present invention further provides a construction work equipment, which includes a driving member, an executive member, and a fastening assembly of any of the above-mentioned embodiments, wherein the driving member has an output shaft, the executive member is installed on the output shaft, and the fastening body is installed on the output shaft and presses the first pressure member against the executive member.

[0024] In the construction work equipment of the embodiment of the present invention, the operating body of the second pressure piece is axially connected to the fastening body, and the fastening body is rotatably inserted into the first pressure piece. In the process of the fastening assembly fastening the actuator to the output shaft of the driving member, the fastening body is used to be installed on the output shaft of the driving member and press the first pressure piece against the actuator, so that the first pressure piece can press the actuator against the output shaft of the driving member, which helps the output shaft of the driving member not to shake easily under the friction of the actuator, and the intermediate piece is arranged between the first pressure piece and the operating body. The second pressure piece rotates relative to the first pressure piece through the intermediate piece to reduce the resistance of the second pressure piece to rotation relative to the first pressure piece, thereby helping the second pressure piece to be installed on the output shaft through the fastening body, so that the actuator can be fastened to the output shaft of the driving member without the use of auxiliary tools, which helps to improve the convenience of operation. In addition, since the fastening body and the operating body are an integrated structure, it helps to reduce the number of parts of the fastening assembly and improve the assembly efficiency of the fastening assembly.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] See also Figure 1 An embodiment of the present invention provides a construction equipment 1000. The construction equipment 1000 can be wall processing equipment such as a putty grinder, a wall grinder, a large white grinder, etc., or it can be a polishing machine, an angle grinder, an electric grinder, a cutting machine, etc.

[0038] See also Figure 2 and Figure 3 The construction equipment 1000 includes a driving member 200, an actuator 300, and a fastening assembly 100. The driving member 200 has an output shaft 201, and the actuator 300 is mounted on the output shaft 201. The fastening assembly 100 can fasten the actuator 300 to the driving member 200. The driving member 200 can drive the actuator 300 to rotate via the output shaft 201, allowing the actuator 300 to perform construction operations. The driving member 200 can be a drive motor.

[0039] The fastening assembly 100 includes a first pressing member 10, a second pressing member 30, and an intermediate member 50. The intermediate member 50 is disposed between the first pressing member 10 and the second pressing member 30. The fastening assembly 100 can abut against the actuator 300 via the first pressing member 10. Since the intermediate member 50 facilitates relative movement between the second pressing member 30 and the first pressing member 10, the first pressing member 10 can press the actuator 300 and the driving member 200, and the second pressing member 30 can fasten the actuator 300 to the driving member 200 by moving relative to the first pressing member 10.

[0040] See also Figure 4 and Figure 5 The second pressing member 30 includes an operating body 31 and a fastening body 33 . The operating body 31 is axially connected to the fastening body 33 . The operating body 31 can facilitate manual operation by the user, so that the user can operate the second pressing member 30 through the operating body 31 .

[0041] The operating body 31 may be provided with a hand-held engagement portion 315, which facilitates handheld operation by the user, making the operating body 31 easy to hold. The hand-held engagement portion 315 may be located on the outer circumference of the operating body 31, thereby preventing the hand-held engagement portion 315 from being positioned at one axial end of the operating body 31 and thereby preventing the hand-held engagement portion 315 from protruding axially from the operating body 31 and affecting the workpiece. The hand-held engagement portion 315 may be a knurled structure formed on the outer circumference of the operating body 31.

[0042] See also Figure 5 and Figure 6 The fastening body 33 is rotatably provided through the first pressing member 10, so that the second pressing member 30 can rotate relative to the first pressing member 10. The fastening body 33 can be fastened to the output shaft 201 of the driving member 200. The fastening body 33 and the output shaft 201 of the driving member 200 can be fastened by a threaded structure. For example, the fastening body 33 can be provided with an external thread, and correspondingly, the output shaft 201 of the driving member 200 can be provided with an internal thread. The internal thread can be provided on the inner surface of the output shaft 201, and the internal thread is adapted to the external thread. Then, the external thread of the fastening body 33 can be threadedly connected with the internal thread of the output shaft 201.

[0043] The fastening body 33 and the operating body 31 can be an integrated structure, which helps to reduce the number of parts of the fastening assembly 100 and improve the assembly efficiency of the fastening assembly 100. It also eliminates the need to design a structure connecting the fastening body 33 and the operating body 31, which helps to simplify the structure of the second pressure piece 30.

[0044] The intermediate member 50 is disposed between the first pressure member 10 and the operating body 31. The intermediate member 50 can move relative to the first pressure member 10 or the operating body 31, thereby facilitating relative movement between the operating body 31 and the first pressure member 10, thereby reducing resistance to rotation of the second pressure member 30 relative to the first pressure member 10. Because the fastening body 33 is mounted on the output shaft 201 of the driver 200 and presses the first pressure member 10 against the actuator 300, the first pressure member 10 can press the actuator 300 against the output shaft 201 of the driver 200, thereby preventing the output shaft 201 of the driver 200 from shaking due to the friction of the actuator 300. When the second pressure piece 30 rotates relative to the first pressure piece 10 through the intermediate piece 50, the second pressure piece 30 can be installed on the output shaft 201 through the fastener 33, so that the actuator 300 can be fastened to the output shaft 201 of the driving piece 200 without using auxiliary tools, which helps to improve the convenience of operation, reduce the labor intensity of replacing the actuator 300, and improve the efficiency of replacing the actuator 300.

[0045] The intermediate member 50 may be a rolling structure. For example, the intermediate member 50 may include a bracket 51 and a plurality of rotating bodies 53. The rotating bodies 53 may be mounted on the bracket 51. For example, each rotating body 53 may be rotatably mounted on the bracket 51. The rotating axis of each rotating body 53 may be perpendicular to the axial direction of the fastening body 33. The second pressing member 30 may be rotated relative to the first pressing member 10 via the rotating body 53. The plurality of rotating bodies 53 may be arranged around the fastening body 33. The plurality of rotating bodies 53 may help to improve the smoothness of the relative rotation between the first pressing member 10 and the second pressing member 30. The rotating body 53 may be a bearing. For example, the rotating body 53 may be a thrust bearing. The rotating body 53 may also be a structure such as a needle roller or a roller. In other embodiments, the intermediate member 50 may be a sliding structure.

[0046] The fastening assembly 100 may further include a seal 70, which may be positioned between the operating body 31 and the first pressure member 10, allowing the seal 70 to contact the operating body 31 and the first pressure member 10, respectively, thereby effectively sealing the gap between the operating body 31 and the first pressure member 10. The seal 70 may be disposed around the intermediate member 50, thereby helping to reduce the risk of external dust and impurities from settling on the intermediate member 50 and affecting its mobility. The seal 70 may be a sealing ring, such as a rubber ring, a silicone ring, or the like.

[0047] The fastening assembly 100 may further include a stopper 90, which may be mounted on the fastening body 33, for example, on the outer circumferential surface of the fastening body 33. The stopper 90 may be located on the side of the first pressing member 10 facing away from the sealing member 70. The stopper 90 may be used to limit the movement of the first pressing member 10 in a direction away from the sealing member 70, thereby facilitating relative movement between the first pressing member 10 and the second pressing member 30 due to external vibrations during transportation of the fastening assembly 100. This may prevent the first pressing member 10 and the second pressing member 30 from moving relative to each other due to excessive spacing between the first pressing member 10 and the operating body 31, thereby preventing the sealing member 70 from being able to resist the operating body 31 and the first pressing member 10. This may help prevent the sealing member 70 from being unable to block dust and impurities, and also help prevent the sealing member 70 from being misaligned due to deviation in position. The stopper 90 may be a retaining ring.

[0048] The structure of the first pressing member 10 can be adjusted according to the structures of the second pressing member 30 and the limiting member 90 .

[0049] For example, the first pressing member 10 may include a pressing member mounting portion 11 and a pressing ring 13, wherein the pressing member mounting portion 11 is connected to the pressing ring 13. The pressing member mounting portion 11 is rotatably mounted on the fastening body 33, and the pressing ring 13 may be connected to a surface of the pressing member mounting portion 11 facing away from the sealing member 70. The first pressing member 10 may abut against the actuator 300 via the pressing ring 13.

[0050] The limit member 90 can be used to limit the movement of the pressure member mounting portion 11 in a direction away from the sealing member 70. The limit member 90 can be located in the cavity 131 surrounded by the pressure ring 13, so that the limit member 90 will not protrude outside the cavity 131 surrounded by the pressure ring 13 while maintaining the restriction on the movement of the first pressure member 10, thereby helping to ensure that the fastening assembly 100 presses the actuator 300 against the driving member 200 through the pressure ring 13 rather than the limit member 90.

[0051] The structure of the second pressing member 30 can be adaptively adjusted according to the structure of the intermediate member 50 .

[0052] For example, the operating body 31 of the second pressure piece 30 may include a mounting boss 311, the fastening body 33 may be connected to the mounting boss 311, and the intermediate piece 50 may be sleeved on the fastening body 33 and set on the mounting boss 311. On the one hand, the mounting boss 311 facilitates the movement of the intermediate piece 50; on the other hand, the intermediate piece 50 always surrounds the fastening body 33 during the movement and will not deviate from the position of the mounting boss 311, which helps to ensure the stability of the intermediate piece 50, thereby helping to improve the stability of the second pressure piece 30 in rotating relative to the first pressure piece 10.

[0053] The structure of the second pressing member 30 can also be adaptively adjusted according to the structure of the sealing member 70 .

[0054] For example, the operating body 31 of the second pressure piece 30 can be provided with a seal installation groove 313, and the seal installation groove 313 can be arranged around the installation boss 311, and the seal 70 can be installed in the seal installation groove 313. This helps to ensure that the seal 70 is installed in the operating body 31 at an accurate position, and also helps to ensure that the position of the seal 70 after being installed in the seal installation groove 313 is not easily shifted due to external vibrations, so that the seal 70 can better prevent external dust and impurities from falling on the middle piece 50.

[0055] The structure of the second pressing member 30 can also be adaptively adjusted according to the structure of the limiting member 90 .

[0056] For example, the fastening body 33 of the second pressure member 30 may be provided with a stopper mounting groove 331. The stopper mounting groove 331 may be provided on the outer circumference of the fastening body 33 and may be an annular groove. The stopper 90 may be sleeved on the fastening body 33 and located within the stopper mounting groove 331. This helps ensure that the stopper 90 is accurately positioned within the fastening body 33 and that the position of the stopper 90, once installed in the stopper mounting groove 331, is not easily displaced by external vibrations. This allows the stopper 90 to effectively restrict movement of the first pressure member 10 away from the sealing member 70.

[0057] In a scenario where the fastening assembly 100 is used to fasten the actuator 300 to the driving member 200, the actuator 300 can be first placed on the output shaft 201 of the driving member 200, and the actuator 300 can be leaned against the step surface 203 of the output shaft 201; then, the operating body 31 of the fastening assembly 100 is held by hand, and the first pressure member 10 is directed toward the actuator 300, and then the fastening body 33 is passed through the actuator 300 and installed on the output shaft 201 of the driving member 200. As the fastener 33 screws into the output shaft 201, the output shaft 201 primarily bears axial force, with the radial force it bears being relatively small and offset by contact with the first pressure piece 10. As the fastener 33 is tightened, the fastener 33 transmits the axial force generated by the threaded pair to the first pressure piece 10 via the intermediate piece 50, and then to the actuator 300 via the first pressure piece 10, causing the actuator 300 to press against the stepped surface 203 of the output shaft 201 with the same axial force, thereby gradually tightening the actuator 300 to the driver 200. After the fastener 33 is tightened, the rotational force generated by the fastener 33 is largely offset by the movement of the intermediate piece 50, so that this embodiment is not affected by the positive pressure generated by the actuator 300 being tightened to the driver 200. This allows the actuator 300 to be easily and quickly tightened manually to the driver 200, while providing a relatively large pressing force for the actuator 300.

[0058] In a scenario where the actuator 300 is removed from the driving member 200 using the fastening assembly 100, the fastening body 33 can be loosened through the operating body 31 first. Since the rotational resistance generated by the output shaft 201 of the actuator 300 and the driving member 200 on the operating body 31 is smaller than the moving friction force of the intermediate member 50, the fastening assembly 100 of this embodiment can facilitate the user to quickly remove the actuator 300.

[0059] See also Figure 2 In addition to the three basic structures of the driving part 200, the executive part 300 and the fastening assembly 100, the construction equipment 1000 may also have additional structures according to the application scenario. For example, the construction equipment 1000 may be a wall treatment device, and the executive part 300 may be a grinding disc. Then the construction equipment 1000 may also include a dust suction pipe 400, a protective cover 500, a dust-proof brush 600, etc. The dust suction pipe 400 can be installed on the driving part 200 through the mounting plate 700. The dust suction pipe 400 can collect the dust generated during the grinding process of the executive part 300. The protective cover 500 can be installed on the executive part 300. The protective cover 500 can prevent the executive part 300 from being damaged and flying out, causing personal injury. The dust-proof brush 600 can be set around the executive part 300. The dust-proof brush 600 can prevent the dust generated during the grinding process from flying out and spreading into the working environment.

[0060] See also Figure 1 and Figure 2 The construction equipment 1000 may further include a horizontal driving mechanism 801, and the driving member 200 may be installed on the horizontal driving mechanism 801. For example, the driving member 200 may be installed on the horizontal driving mechanism 801 through a hinge seat 205, so that the horizontal driving mechanism 801 can drive the executive member 300 to move in the horizontal direction, which helps to improve the flexibility of the executive member 300 in performing construction operations in the horizontal direction.

[0061] The construction equipment 1000 can also include a vertical drive mechanism 802. The horizontal drive mechanism 801 can be installed on the vertical drive mechanism 802. The vertical drive mechanism 802 can drive the horizontal drive mechanism 801 to move, thereby driving the actuator 300 to move in the vertical direction, which helps to improve the flexibility of the actuator 300 in performing construction operations in the vertical direction.

[0062] The construction equipment 1000 may further include a driving chassis 803 , and the vertical driving mechanism 802 may be mounted on the driving chassis 803 . The driving chassis 803 has a plurality of driving wheels, and the driving chassis 803 may enable the construction equipment 1000 to move on the ground.

[0063] In the fastening assembly 100 and the construction work equipment 1000 of the embodiment of the present invention, the operating body 31 of the second pressure member 30 is axially connected to the fastening body 33, and the fastening body 33 is rotatably provided on the first pressure member 10. In the process of the fastening assembly 100 fastening the actuator 300 to the output shaft 201 of the driving member 200, the fastening body 33 is used to be installed on the output shaft 201 of the driving member 200 and to press the first pressure member 10 against the actuator 300, so that the first pressure member 10 can press the actuator 300 against the output shaft 201 of the driving member 200, which helps the driving member 200 to be tightened. The output shaft 201 of the actuator 200 is not easily shaken due to the friction of the actuator 300, and the intermediate member 50 is disposed between the first pressure member 10 and the operating body 31. The second pressure member 30 rotates relative to the first pressure member 10 via the intermediate member 50, thereby reducing the resistance to the rotation of the second pressure member 30 relative to the first pressure member 10. This helps the second pressure member 30 be installed on the output shaft 201 through the fastener 33, so that the actuator 300 can be fastened to the output shaft 201 of the driver 200 without the use of auxiliary tools, which helps to improve the convenience of operation. In addition, because the fastener 33 and the operating body 31 are an integrated structure, it helps to reduce the number of parts of the fastening assembly 100 and improve the assembly efficiency of the fastening assembly 100.

[0064] See also Figure 7The above-mentioned construction equipment 1000 can also be used as a robot 2000, which includes a robot body 900, a driving member 200, an actuator 300, and a fastening assembly 100 according to any of the above-mentioned embodiments. The robot body 900 can be adjusted according to the application scenario of the robot 2000. For example, the robot body 900 can be a robotic arm. The driving member 200 is provided on the robot body 900. The driving member 200 has an output shaft 201. The actuator 300 is mounted on the output shaft 201. The fastening body 33 is mounted on the output shaft 201 of the driving member 200 and causes the first pressing member 10 to be pressed against the actuator 300.

[0065] In the robot 2000 of the embodiment of the present invention, the operating body 31 of the second pressing member 30 is axially connected to the fastening body 33, and the fastening body 33 is rotatably provided on the first pressing member 10. When the fastening assembly 100 fastens the actuator 300 to the output shaft 201 of the driving member 200, the fastening body 33 is used to be installed on the output shaft 201 of the driving member 200 and to press the first pressing member 10 against the actuator 300, so that the first pressing member 10 can press the actuator 300 against the output shaft 201 of the driving member 200, which helps the output of the driving member 200 to be faster. The rotating shaft 201 is less likely to wobble due to the friction of the actuator 300. Furthermore, the intermediate member 50 is disposed between the first pressure member 10 and the operating body 31. The second pressure member 30 rotates relative to the first pressure member 10 via the intermediate member 50, thereby reducing the resistance to rotation of the second pressure member 30 relative to the first pressure member 10. This facilitates the installation of the second pressure member 30 on the output rotating shaft 201 via the fastener 33. This allows the actuator 300 to be fastened to the output rotating shaft 201 of the driver 200 without the use of auxiliary tools, thereby improving operational convenience. Furthermore, since the fastener 33 and the operating body 31 are integrally structured, the number of parts in the fastening assembly 100 is reduced, thereby improving assembly efficiency.
