[0044] The beneficial effects of the embodiments of the present application are that the first positioning hole 21 and the second positioning hole 31 are in interference fit with the same connecting piece 40, the center lines of the first positioning hole 21 and the second positioning hole 31 coincide, the first positioning hole 21 and the second positioning hole 31 can be positioned at the same position in the circumferential direction of the rotating piece 10, and the installation error of the relative position of the first cam 20 and the second cam 30 during installation is reduced. The embodiments of the present application can solve the technical problem of large installation error of the relative position of the two cams at one end of the lifting and transferring machine.

[0045] When multiple cam mechanisms 100 are arranged in the lifting and transferring machine to jointly lift an object, the relative position error of the first cam 20 and the second cam 30 in the same cam mechanism 100 is small, the cumulative installation error of the multiple first cams 20 and the multiple second cams 30 in the multiple cam mechanisms 100 is small, and the pressure of the object can be uniformly distributed to the multiple first cams 20 and the multiple second cams 30.

[0046] When the first cam 20 and the second cam 30 lift the same object, the relative position error of the first cam 20 and the second cam 30 is small, and the pressure of the object can be uniformly distributed to the first cam 20 and the second cam 30.

[0049] The first step limiting surface 431 abuts against one end of the first cam 20 close to the second cam 30 along the first direction X, which can block the first cam 20 from moving close to the second cam 30 along the first direction X and limit the axial position of the first cam 20.

[0050] The second step limiting surface 432 intersects the first direction X and intersects the side surface of the second connecting segment 42 to form a stepped shape. Optionally, the second step limiting surface 432 can be formed by setting a flange on the side surface of the second connecting segment 42.

[0054] The recess 13 is recessed from the side of the rotating member 10 towards the direction close to the axis of the rotating member 10. In the first direction X, the recess 13 can extend from the middle of the rotating member 10 to one end surface of the rotating member 10, or the recess 13 can extend from one end of the rotating member 10 to the end surface of the other end.

When the rotating member 10 rotates, the recess 13 abuts against the first flange 43 and drives the first flange 43 to rotate synchronously with the recess 13, so as to prevent the connecting member 40 from moving along the circumferential direction of the rotating member 10. Optionally, the first flange 43 is interference-fitted with the recess 13, and the installation precision of the first flange 43 relative to the recess 13 is higher.

By matching the first flange 43 with the recess 13, the connecting member 40 can be prevented from moving along the circumferential direction of the rotating member 10, that is, the first positioning hole 21 and the second positioning hole 31 can be prevented from moving along the circumferential direction of the rotating member 10, and the first cam 20 and the second cam 30 can be prevented from rotating relative to the rotating member 10.

[0058] In some embodiments, please refer to Figure 4 The first cam 20 is provided with the first protrusion 24 interference-fitted with the recess 13, so as to hinder the first cam 20 from rotating relative to the rotating member 10.

[0059] The first cam 20 comprises the first connecting hole 23 accommodating the rotating member 10, and the first protrusion 24 is protruded from the hole wall of the first connecting hole 23 towards the axis of the first connecting hole 23.

[0061] In some embodiments, referring to Figure 4 , the second protrusion 34 on the second cam 30 is in interference fit with the recessed part 13, which can hinder the rotation of the second cam 30 relative to the rotating member 10.

[0062] The second cam 30 includes a second connecting hole 33 accommodating the rotating member 10, and the second protrusion 34 protrudes from the hole wall of the second connecting hole 33 to the axis of the second connecting hole 33. The second protrusion 34 is in interference fit with the recessed part 13, that is, the second protrusion 34 protrudes in the recessed direction of the recessed part 13 in the recessed part 13, and the second protrusion 34 and the recessed part 13 are in mutual abutment, that is, the second connecting hole 33 and the rotating member 10 are in mutual abutment and interference fit.

[0063] The beneficial effects of the embodiments of the present application are that the second protrusion 34 on the second cam 30 is in interference fit with the recessed part 13, which can accurately position the position of the second protrusion 34 in the circumferential direction of the rotating member 10, that is, accurately position the position of the second cam 30 in the circumferential direction of the rotating member 10; the second connecting hole 33 and the rotating member 10 can accurately position the position of the second cam 30 in the radial direction of the rotating member 10, thereby improving the installation accuracy of the second cam 30 on the rotating member 10.

[0064] In some embodiments, referring to Figure 4 , the first protrusion 24 on the first cam 20 is in interference fit with the recessed part 13, which can hinder the rotation of the first cam 20 relative to the rotating member 10; the second protrusion 34 on the second cam 30 is in interference fit with the recessed part 13, which can hinder the rotation of the second cam 30 relative to the rotating member 10, thereby improving the installation accuracy of the first cam 20 and the second cam 30 on the rotating member 10, and further reducing the error of the relative position of the first cam 20 and the second cam 30.

[0065] In some embodiments, referring to Figure 3 and Figure 4 , the second flange 11 on the rotating member 10 abuts the end of the first cam 20 away from the second cam 30 along the first direction X.

[0066] The second flange 11 is protrudingly arranged on the side of the rotating member 10. In the first direction X, the second flange 11 is arranged on the side of the first cam 20 away from the second cam 30, and the second flange 11 abuts against the end of the first cam 20 away from the second cam 30, so as to block the first cam 20 from moving away from the second cam 30 in the first direction X, and limit the axial position of the first cam 20.

[0067] The beneficial effect of the embodiment of the present application is that the second flange 11 is arranged to abut against the first cam 20, so as to limit the axial position of the first cam 20, and facilitate positioning the first cam 20 during installation.

[0068] In some embodiments, referring to Figure 2 , the first cam 20 is provided with a first protruding portion 22, and the second cam 30 is provided with a second protruding portion 32, and the first protruding portion 22 and the second protruding portion 32 are arranged staggered.

[0069] The first protruding portion 22 refers to the part farthest from the rotation axis of the first cam 20 in the radial direction of the first cam 20. The second protruding portion 32 refers to the part farthest from the rotation axis of the second cam 30 in the radial direction of the second cam 30. The first protruding portion 22 and the second protruding portion 32 are arranged staggered, which means that in the circumferential direction of the rotating member 10, the first protruding portion 22 and the second protruding portion 32 are located at different positions.

[0070] When the first cam 20 drives the object to move, when the first protruding portion 22 gradually approaches the object, the object moves away from the rotating member 10, and when the first protruding portion 22 gradually moves away from the object, the object moves towards the rotating member 10.
