[0103] The embodiment of the present disclosure provides a following device 30. Figure 1 and Figure 2 As shown, the follower device 30 includes a first coupling end 32 and a second coupling end 34. The first coupling end 32 and the second coupling end 34 have a mating width in a first direction F and a guiding length in a second direction S orthogonal to the first direction F. One of the first coupling end 32 and the second coupling end 34 can drive the other to move in the first direction F and guide the other to move in the second direction S. At least one of the first coupling end 32 and the second coupling end 34 is an adjustable end, and the mating width of the adjustable end is adjustable.

[0104] In the technical solution provided by the embodiments of the present disclosure, by making the mating width of the adjustable end adjustable, the mating accuracy between the first coupling end and the second coupling end can be adjusted by varying the mating width, thereby eliminating the need for high machining precision for the first coupling end and the second coupling end. This allows the follower device to have lower manufacturing costs. Furthermore, even if the mating precision of the first coupling end and the second coupling end decreases due to wear and tear after prolonged use, the mating precision can be maintained by adjusting the mating width, thereby allowing the follower device to have lower maintenance costs.

[0105] In some examples, such as Figure 1 and Figure 2 As shown, the first coupling end 32 is an adjustable end, and the second coupling end 34 is a non-adjustable end. Here, the mating width of the non-adjustable end is not adjustable. In other examples, the first coupling end 32 and the second coupling end 34 can both be adjustable ends, or the first coupling end 32 can be a non-adjustable end.

[0106] In some examples, the first direction F is a horizontal direction, and the second direction S is a vertical direction.

[0107] In some examples, such as Figure 1 and Figure 2 As shown, the second coupling end 34 drives the first coupling end 32 to move along the first direction F and guides the first coupling end 32 to move along the second direction S. In other examples, the first coupling end 32 can drive the second coupling end 34 to move along the first direction F and guide the second coupling end 34 to move along the second direction S.

[0108] In some examples, such as Figure 2As shown, the adjustable end includes a first adjustment element 36 and a second adjustment element 38. The first adjustment element 36 and the second adjustment element 38 are arranged opposite to each other in a first direction F. The first adjustment element 36 and the second adjustment element 38 can move closer to and farther from each other in the first direction F to change the fitting width of the adjustable end.

[0109] In some examples, such as Figure 2 As shown, the adjustable end further includes a track and a positioning element 40. The track extends in a first direction F, and the positioning element 40 can be locked or unlocked with the track. When the positioning element 40 is locked with the track, the first adjustment element 36 is fixed to the track or the positioning element 40. After the positioning element 40 is unlocked from the track, the positioning element 40 can move along the track in the first direction F, thereby enabling the first adjustment element 36 to move along the track in the first direction F.

[0110] In some examples, such as Figure 2 、 Figure 6 as well as Figure 8 As shown, the adjustable end further includes a sliding seat 94. The track is a waist-shaped hole provided on the sliding seat 94, extending in a first direction F. The positioning element 40 is a fastener that passes through the track. When the positioning element 40 is tightened, it locks with the track, and at least a portion of the first adjustment element 36 and the positioning element 40 are fixed relative to the sliding seat 94. When the positioning element 40 is loosened, the positioning element 40 is unlocked from the track, and the first adjustment element 36 and the positioning element 40 can move relative to the sliding seat 94 in the first direction F.

[0111] In some examples, such as Figure 2 As shown, at least a portion of the second adjusting element 38 is fixedly connected to the sliding seat 94 .

[0112] In some examples, such as Figure 2 As shown, the first adjusting element 36 and / or the second adjusting element 38 include rollers 42. In this way, the first coupling end 32 can be smoothly guided by the second coupling end 34, thereby facilitating improved matching accuracy between the first coupling end 32 and the second coupling end 34.

[0113] In some examples, such as Figure 2 As shown, roller 42 is a pulley.

[0114] In some examples, such as Figure 2 As shown, the roller 42 of the first adjusting element 36 and the roller 42 of the second adjusting element 38 are arranged opposite each other in a first direction F.

[0115] In some examples, such as Figure 2As shown, the adjustable end further includes a stopper element 44, which is used to limit the movement of one of the first adjusting element 36 and the second adjusting element 38 toward or away from the other. Thus, the stopper element 44 can share the load of the first adjusting element 36 or the second adjusting element 38 in the first direction F, thereby enhancing the reliability of the follower device 30. Furthermore, the stopper element 44 can also be used to precisely adjust the distance between the first adjusting element 36 or the second adjusting element 38, making the distance between the first adjusting element 36 and the second adjusting element 38 easier to adjust.

[0116] In some examples, such as Figure 2 As shown, the adjustable end further includes a seat member 46 and a locking member 48. The limiting member 44 is threadedly engaged with the seat member 46. The limiting member 44 is configured to be rotatable relative to the seat member 46 when the locking member 48 is in the unlocked state, so as to move in the first direction F. Furthermore, the limiting member 44 is configured to be fixed relative to the seat member 46 when the locking member 48 is in the locked state.

[0117] In some examples, such as Figure 2 As shown, the limiting element 44 is screwed into the locking element 48. The locking element 48 can rotate relative to the limiting element 44 to switch between a locked state and an unlocked state.

[0118] In some examples, such as Figure 2 As shown, the limiting element 44 is a jackscrew and the locking element 48 is a nut. When the locking element 48 is tightened, the locking element 48 is in a locked state. When the locking element 48 is not tightened, the locking element 48 is in an unlocked state.

[0119] In some examples, such as Figure 2 As shown, the first coupling end 32 includes a channel 50, and the second coupling end 34 includes a guide post 52. The guide post 52 is disposed within the channel 50, and the channel 50 and the guide post 52 have a mating width and a guide length. One of the channel 50 and the guide post 52 is provided with a recess 54, and the other of the channel 50 and the guide post 52 is provided with a protrusion 56. The recess 54 receives the protrusion 56, so that the first coupling end 32 and the second coupling end 34 are mutually restrained in a third direction T that is orthogonal to both the first direction F and the second direction S. In this way, by restraining the first coupling end 32 and the second coupling end 34 in the third direction T, the mating accuracy between the first coupling end 32 and the second coupling end 34 is further improved.

[0120] In some examples, the third direction T is a horizontal direction.

[0121] In some examples, such as Figure 2As shown, the channel 50 is defined by the first adjustment element 36 and the second adjustment element 38. In other words, the channel 50 is the space between the first adjustment element 36 and the second adjustment element 38. The guide post 52 can extend into the space between the first adjustment element 36 and the second adjustment element 38 to be located in the channel 50.

[0122] In some examples, such as Figure 1 As shown, the channel 50 is provided with a recessed portion 54 and the guide post 52 is provided with a raised portion 56 .

The guide rails 72 extend in the second direction S, and the nut 68 is connected to the guide rails 72 via the sliders 74. When the nut 68 moves in the second direction S, it is guided by the guide rails 72. In this way, the guide rails 72 and sliders 74 can share the load on the screw 66 and the nut 68, thereby extending the service life of the screw 66 and the nut 68.

[0134] In some examples, such as Figure 6 and Figure 8 As shown, the follower device 30 further includes a moving plate 76 . The nut 68 is fixedly connected to the slider 74 via the moving plate 76 .

For example, the screw rod 66 can be supported on the mounting seat 84 by a bearing.

[0140] In some examples, the bearing supporting the screw 66 for rotation is configured to float along the second direction S. In this way, the bearing can adapt to the length of the screw 66 when the screw 66 elongates due to temperature increase, thereby facilitating improved transmission accuracy of the screw 66 .
