During installation, a positioning tool is used to connect the two cam mechanisms, the positions of the two cam mechanisms in the circumferential direction of the rotating member are positioned, the cam mechanisms are fixed, and then the positioning tool is removed. Since the positioning tool and the cam mechanisms are detachably connected, the time gap of the connection between the positioning tool and the cam mechanisms is large, the installation precision of the cam mechanisms is low, and the relative position error of the two cam mechanisms in the circumferential direction of the rotating member is large, which easily leads to uneven pressure of the object on the two cam mechanisms.

[0032] The first aspect of this application provides a lifting mechanism for driving an object to move back and forth. This application uses the lifting mechanism in a lifting transfer machine as an example for illustration. It can be understood that the lifting mechanism can also be used in other equipment.

[0033] An embodiment of the first aspect of this application provides a lifting mechanism; please refer to... Figures 1 to 3 The lifting mechanism 100 includes a power mechanism 10, two cam mechanisms 20, and two connecting keys 40. The power mechanism 10 includes a power assembly 11 and a first rotating member 12 connected to the power assembly 11. The power assembly 11 drives the first rotating member 12 to rotate. The first rotating member 12 extends along a first direction X, and both ends of the first rotating member 12 along the first direction X have notches 121, which are directly opposite each other along the first direction X. The two cam mechanisms 20 are respectively connected to the two ends of the first rotating member 12 along the first direction X; the two connecting keys 40 are respectively connected to the two cam mechanisms 20, and the two connecting keys 40 are respectively interference-fitted with the two notches 121 to position the two cam mechanisms 20.

[0034] The power component 11 includes devices such as an electric motor or a hydraulic motor.

[0035] The first rotating member 12 has an axis and is driven by the power assembly 11 to rotate about the axis. Optionally, the first rotating member 12 can be a shaft, a sleeve, etc.

[0036] The notch 121 extends from the end face of the first rotating member 12 along the first direction X into the first rotating member 12. The notch 121 is open on the end face of the first rotating member 12 along the first direction X and on a surface adjacent to the end face.

[0037] The two notches 121 are positioned opposite each other along the first direction X, meaning that the two notches 121 are in the same or substantially the same position in the circumferential direction of the first rotating member 12, and in any direction perpendicular to the first direction X, the two notches 121 are in the same or substantially the same position. Optionally, the two notches 121 are formed using the same steps, which can reduce the relative positional error of the two notches 121.

[0038] The cam mechanism 20 may include one cam or multiple cams. Two cam mechanisms 20 are respectively connected to both ends of the first rotating member 12 along the first direction X, meaning that the two cam mechanisms 20 are fixed to the first rotating member 12 and can rotate synchronously with the first rotating member 12. The two cam mechanisms 20 are used to jointly support and drive the movement of the same object, and the pressure of the object is transmitted to both ends of the first rotating member 12 along the first direction X through the two cam mechanisms 20. Optionally, the cam mechanism 20 and the first rotating member 12 can be fixed by bolts, welding, or other methods.

[0039] The two cam mechanisms 20 are arranged facing each other along the first direction X, meaning that the projections of the two cam mechanisms 20 coincide or substantially coincide on the projection plane perpendicular to the first direction X. Optionally, the two cam mechanisms 20 are formed using the same steps, which can reduce the machining error of the two cam mechanisms 20 and reduce the error in the relative position of the two cam mechanisms 20 in the lifting mechanism 100.

[0040] The connecting key 40 is fixed to the cam mechanism 20. Optionally, the connecting key 40 can be directly connected to the cam mechanism 20, in which the cam is sleeved on the first rotating member 12. Optionally, the connecting key 40 can also be connected to the cam mechanism 20 through other components.

[0041] Two connecting keys 40 are respectively interference-fitted with two notches 121 to position the two cam mechanisms 20. This means that the two connecting keys 40 are respectively located within the two notches 121, with the connecting keys 40 abutting against the walls of the notches 121 along the circumference of the first rotating member 12. The surfaces of the connecting keys 40 at both ends along the circumference of the first rotating member 12 are tightly fitted against the walls of the notches 121. When installing the cam mechanism 20, inserting the connecting keys 40 into the notches 121 positions the connecting keys 40 in the circumferential direction of the first rotating member 12, which in turn positions the various parts of the cam mechanism 20 in the circumferential direction of the first rotating member 12. The two notches 121 and the two cam mechanisms 20 are directly opposite each other, meaning that the two connecting keys 40 are at the same or substantially the same circumferential position in the connected cam mechanism 20. Optionally, the connecting keys 40 can extend from one end of the notch 121 to the other along the first direction X to reduce the gap between the connecting keys 40 and the notches 121. Optionally, in the first direction X, the connecting keys 40 can also be smaller than the size of the notches 121.

[0042] During installation, insert the two connecting keys 40 into the two notches 121 respectively, so that the whole consisting of the cam mechanism 20 and the connecting keys 40 is connected to the cam mechanism 20, and the two cam mechanisms 20 are facing each other along the first direction X.

[0043] For example, when the lifting mechanism 100 drives the object to rise or fall, the object is placed on two cam mechanisms 20. The power component 11 drives the first rotating member 12 to rotate. The first rotating member 12 drives the connecting key 40 and the cam mechanism 20 to rotate. The two cam mechanisms 20 together drive the object to rise or fall.

[0044] The beneficial effects of this application embodiment are as follows: The two cam mechanisms 20 can drive and stably support the object; the two connecting keys 40 are respectively interference-fitted with the two notches 121, which can accurately position the connecting keys 40 in the circumferential direction of the first rotating member 12, that is, accurately position the two cam mechanisms 20 in the circumferential direction of the first rotating member 12, reducing the relative position error of the two cam mechanisms 20. When the two cam mechanisms 20 support the same object, the pressure of the object can be evenly distributed to the two cam mechanisms 20, making the first rotating member 12 subjected to uniform force, which is beneficial to improving the service life of the lifting mechanism 100; this application embodiment can solve the technical problem of large relative position error of the two cam mechanisms in the circumferential direction of the rotating member in the lifting transfer machine.

[0045] In some embodiments, please refer to Figure 4 The connecting key 40 includes a plug portion 41 and a main body portion 42 arranged along a first direction X. In the first direction X, the cross-sectional area of ​​the plug portion 41 gradually increases from the end away from the main body portion 42 to the end closer to the main body portion 42.

[0046] The plug portion 41 refers to the part that first enters the notch 121 when the connecting key 40 is inserted into the notch 121 along the first direction X. The plug portion 41 is directly opposite the closed end of the notch 121 along the first direction X, and the main body portion 42 is located on the side of the plug portion 41 away from the closed end of the notch 121 along the first direction X.

[0047] In the first direction X, the cross-sectional area of ​​the insertion portion 41 gradually increases from the end away from the main body portion 42 to the end closer to the main body portion 42. That is, the circumferential dimension of the insertion portion 41 in the first rotating member 12 gradually increases from the end away from the main body portion 42 to the end connected to the main body portion 42. The insertion portion 41 is inclined on two surfaces along the circumferential direction of the first rotating member 12, and the circumferential dimension of the main body portion 42 in the first rotating member 12 is larger than the circumferential dimension of the end of the insertion portion 41 away from the main body portion 42. Since the main body portion 42 passes through the end of the notch 121 that opens along the first direction X when inserted into the notch 121, the circumferential dimension of the end of the notch 121 that opens along the first direction X in the first rotating member 12 is close to the circumferential dimension of the main body portion 42 in the first rotating member 12, and the circumferential dimension of the end of the notch 121 that opens along the first direction X in the first rotating member 12 is larger than the circumferential dimension of the end of the insertion portion 41 that is away from the main body portion 42 in the first direction X in the first rotating member 12. Here, cross-sectional area refers to the area on a section perpendicular to the first direction X.

[0048] The beneficial effects of this application embodiment are as follows: the cross-sectional area of ​​the plug portion 41 gradually increases from the end away from the main body portion 42 to the end close to the main body portion 42, so that the dimension of the end of the notch 121 that opens in the first direction X in the circumferential direction of the first rotating member 12 is greater than the dimension of the end of the plug portion 41 that is away from the main body portion 42 in the first direction X in the circumferential direction of the first rotating member 12, making it easier to insert the plug portion 41 into the notch 121; the two end faces of the plug portion 41 are inclined along the circumferential direction of the first rotating member 12, which can guide the main body portion 42 into the notch 121, making it convenient to insert the connecting key 40 into the notch 121 during installation.

[0049] In some embodiments, please refer to Figure 2 and Figure 3 The first rotating component 12 is a drum, and the power assembly 11 is located inside the drum. The lifting mechanism 100 also includes two second rotating components 30, which are inserted into the end of the drum along the first direction X to close the drum. Two cam mechanisms 20 are respectively sleeved on the two second rotating components 30, and two connecting keys 40 are respectively located on the two second rotating components 30.

[0050] The power mechanism 10 is a drum motor. Optionally, the power assembly 11 may include a motor and a gear reduction mechanism, with the motor connected to the drum via the gear reduction mechanism.

[0051] The second rotating component 30 is fixed to the drum and can rotate with the drum. Both ends of the drum are open along the first direction X. The second rotating component 30 is inserted into the drum through the opening at one end along the first direction X, closing the opening. Optionally, the annular outer surface of the second rotating component 30 extending along the first direction X seals against the inner wall of the drum, providing a good sealing effect. Optionally, there can also be a small gap between the annular outer surface of the second rotating component 30 extending along the first direction X and the inner wall of the drum. The second rotating component 30 has a cylindrical surface adapted to the inner wall of the drum and a cylindrical surface adapted to the cam in the cam mechanism 20, so that the axis of the cam in the cam mechanism 20, the axis of the second rotating component 30, and the axis of the drum coincide or substantially coincide. Optionally, the second rotating component 30 can be a sleeve, end cap, or other element with through holes, facilitating the fixing of the power assembly 11 to an external component of the drum. Optionally, blind holes can also be provided on the second rotating component 30, providing a better sealing effect on the drum when the lifting mechanism 100 is not installed or in use.

[0052] Both the cam mechanism 20 and the connecting key 40 are fixed to the second rotating member 30. The rotation of the roller can drive the connecting key 40 to rotate, which in turn drives the second rotating member 30 and the cam mechanism 20 to rotate. The connecting key 40 is connected to the annular outer surface of the roller extending along the first direction X.

[0053] During installation, a support shaft 50 is used to pass through the second rotating member 30 and connect to the power assembly 11. The support shaft 50 supports the second rotating member 30 and the power assembly 11. After the support shaft 50 is fixed, the power assembly 11 remains stable and can drive the roller and the second rotating member 30 to rotate around the support shaft 50.

[0054] The beneficial effect of this application embodiment is that by setting the power assembly 11 inside the drum and setting the second rotating member 30 to close the drum, the power assembly 11 can be separated from the external environment of the drum, preventing dust and other debris from entering the power assembly 11.

[0055] In some embodiments, the second rotating member 30 is interference-fitted with the roller, that is, the second rotating member 30 and the inner wall of the roller abut against each other along the radial direction of the roller, and the outer surface of the second rotating member 30 extending along the first direction X is in close contact with the inner wall of the roller, which can improve the coaxiality of the second rotating member 30 and the roller, improve the coaxiality of the two second rotating members 30 connected to the roller, reduce the relative position error of the two cam mechanisms 20 on the two second rotating members 30, and when the two cam mechanisms 20 support the object together, the pressure of the object is evenly distributed to the two cam mechanisms 20.

[0056] In some embodiments, the cam mechanism 20 is interference-fitted with the second rotating member 30.

[0057] The cam in the cam mechanism 20 has a mounting hole. The wall of the mounting hole of the cam in the cam mechanism 20 abuts against the second rotating member 30. The wall of the mounting hole is in close contact with the outer surface of the second rotating member 30 extending along the first direction X. This can improve the coaxiality between the cam in the cam mechanism 20 and the second rotating member 30, improve the coaxiality of the cams in the two cam mechanisms 20, and reduce the error in the relative position of the cams. When the two cam mechanisms 20 support an object together, the pressure of the object is evenly distributed on the multiple cams of the two cam mechanisms 20.

[0058] In some embodiments, the second rotating member 30 is interference-fitted with the roller, and the cam mechanism 20 is interference-fitted with the second rotating member 30, further improving the coaxiality of the cams in the two cam mechanisms 20. When the two cam mechanisms 20 support the object together, the pressure of the object is evenly distributed on the multiple cams of the two cam mechanisms 20, preventing the roller from being damaged due to excessive local pressure.

[0059] In some embodiments, please refer to Figure 3 The second rotating member 30 is provided with a flange 31, which abuts against the end face of the roller along the first direction X.

[0060] The flange 31 protrudes from the outer surface of the second rotating member 30 extending along the first direction X in a direction away from the axis of the second rotating member 30. The end face of the flange 31 along the first direction X abuts against the end face of the roller along the first direction X, preventing the second rotating member 30 from approaching the roller along the first direction, thus facilitating the positioning of the axial position of the second rotating member 30 during installation.

[0061] In some embodiments, please refer to Figure 3 and Figure 4 The connecting key 40 and the second rotating component 30 are integrated into one structure, which improves production efficiency.

[0062] In some embodiments, please refer to Figure 3 and Figure 4 The notch 121 extends from the outer surface of the roller to the inner surface of the roller along its own axis and the roller axis. That is, in the direction of the arrangement of the notch 121 and the roller axis, both ends of the notch 121 are open, and the notch 121 connects the inside of the roller and the outside of the roller. The direction of the arrangement of the notch 121 and the roller axis is the radial direction of the roller. The size of the notch 121 in this radial direction of the roller is large, which increases the contact area between the notch 121 and the connecting key 40, and the connection between the connecting key 40 and the notch 121 is more stable.

[0063] In some embodiments, please refer to Figure 1 In the first direction X, the connecting key 40 extends from one end of the notch 121 to the other end of the notch 121 to close the notch 121.

[0064] In the first direction X, one end of the connecting key 40 is flush with the end face of the roller, and the other end of the connecting key 40 contacts the closed end of the notch 121. The connecting key 40 closes the notch 121, that is, both ends of the connecting key 40 in the first direction X are flush with both ends of the notch 121, and the two end faces of the connecting key 40 in the circumferential direction of the roller are tightly fitted with the wall of the notch 121. The connecting key 40 fills the notch 121, preventing dust and other debris from entering the roller from the notch 121, thus ensuring stable operation of the power assembly 11. When a flange 31 is provided on the second rotating member 30, the connecting key 40 extends along one end in the first direction X to the flange 31.

[0065] In some embodiments, please refer to Figure 5 The cam mechanism 20 includes a first cam 21 and a second cam 22. The first cam 21 is provided with a first protrusion 211, and the second cam 22 is provided with a second protrusion 221. The first protrusion 211 and the second protrusion 221 are staggered.

[0066] The first protrusion 211 refers to the portion of the first cam 21 that is furthest from its axis along the radial direction of the first cam 21. The second protrusion 221 refers to the portion of the second cam 22 that is furthest from its axis along the radial direction of the second cam 22. The first protrusion 211 and the second protrusion 221 are offset from each other, meaning that the first protrusion 211 and the second protrusion 221 are located at different positions in the circumferential direction of the second rotating member 30.

[0067] For example, when the lifting mechanism 100 drives two objects to rise and fall, the first object is placed on the two first cams 21 of the two cam mechanisms 20, and the second object is placed on the two second cams 22 of the two cam mechanisms 20. The power assembly 11 drives the first rotating member 12 to rotate, and the first rotating member 12 drives the first cam 21 and the second cam 22 to rotate synchronously. As the first protrusion 211 gradually approaches the first object, the second protrusion 221 gradually moves away from the second object. The first object moves away from the axis of the first rotating member 12 and rises, while the second object moves closer to the axis of the first rotating member 12 and falls. As the first protrusion 211 gradually moves away from the first object, the second protrusion 221 gradually approaches the second object. The first object moves closer to the axis of the first rotating member 12 and falls, while the second object moves away from the axis of the first rotating member 12 and rises. The first object and the second object rise and fall alternately.

[0068] The beneficial effect of this application embodiment is that: the first protrusion 211 and the second protrusion 221 are staggered, so the first cam 21 and the second cam 22 can drive two objects to move in opposite directions respectively, and the lifting mechanism 100 has a wider range of applications.

[0069] In some embodiments, please refer to Figures 1 to 4The lifting mechanism 100 includes a power mechanism 10, two second rotating members 30, two cam mechanisms 20, and two connecting keys 40. The power mechanism 10 includes a power assembly 11 and a first rotating member 12 connected to the power assembly 11; the first rotating member 12 extends along a first direction X and is a roller; both ends of the first rotating member 12 along the first direction X are provided with notches 121, and the two notches 121 are arranged opposite each other along the first direction X; the power assembly 11 is used to drive the first rotating member 12 to rotate, and the power assembly 11 is located inside the roller.

[0070] Two second rotating members 30 are respectively inserted into both ends of the roller along the first direction X to close the roller; the second rotating members 30 are interference-fitted with the roller. Two cam mechanisms 20 are respectively sleeved on the two second rotating members 30, and the cam mechanisms 20 are interference-fitted with the second rotating members 30.

[0071] Two connecting keys 40 are respectively disposed on the two second rotating members 30. The two connecting keys 40 are respectively interference-fitted with the two notches 121 to position the two cam mechanisms 20. The connecting key 40 includes a plug portion 41 and a main body portion 42 arranged along the first direction X. In the first direction X, the cross-sectional area of ​​the plug portion 41 gradually increases from the end away from the main body portion 42 to the end closer to the main body portion 42.

[0072] The second aspect of this application also provides a lifting and transfer machine, which includes a first conveying mechanism, a second conveying mechanism, and a lifting mechanism 100 of any one of the embodiments of the first aspect. The first conveying mechanism and the second conveying mechanism are used to convey items in different directions. The cam mechanism 20 includes a first cam 21 and a second cam 22. The first cam 21 is provided with a first protrusion 211, and the second cam 22 is provided with a second protrusion 221. The two first protrusions 211 and the two second protrusions 221 are staggered. The first cam 21 is used to lift the first conveying mechanism, and the second cam 22 is used to lift the second conveying mechanism.

[0073] The first conveying mechanism is located on two first cams 21. Optionally, the first conveying mechanism can be a conveyor belt mechanism, a conveyor roller mechanism, etc.

[0074] The second conveying mechanism is located on two second cams 22. Optionally, the second conveying mechanism can be a conveyor belt mechanism, a conveyor roller mechanism, etc.

[0075] The first protrusion 211 and the second protrusion 221 are misaligned, meaning that the first cam 21 and the second cam 22 can respectively lift the first conveying mechanism and the second conveying mechanism to move in opposite directions.

[0076] In use, the power component 11 drives the first rotating member 12 to rotate, and the first rotating member 12 drives the first cam 21 and the second cam 22 to rotate. The first cam 21 and the second cam 22 drive the first conveying mechanism and the second conveying mechanism to rise alternately, which can alternately transport items to different directions.

[0077] The beneficial effects of the embodiments of this application are as follows: The lifting and transfer machine provided by the embodiments of this application includes the lifting mechanism 100 of any one of the first aspect embodiments, which can accurately position the two cam mechanisms 20 in the upward position of the first rotating member 12 circumferences, reduce the error in the relative position of the two cam mechanisms 20, and have all the advantages of the lifting mechanism 100.
