For a use scenario of an existing coupler, in order to solve a problem that a position between a driving member and a driven member coupled by the coupler is relatively fixed due to a structural limitation of the coupler, so that a flexible adjustment of a distance between the driving member and the driven member cannot be performed based on an actual use requirement, an embodiment of the present application provides a coupler, which can be applied to a coupling scenario of the driving member and the driven member, please refer to fig. 1, fig. 2, and fig. 3 to understand the embodiment, fig. 1 is a schematic structural diagram of the coupler provided in the embodiment, fig. 2 is a schematic use scenario diagram of the coupler provided in the embodiment, and fig. 3 is a schematic connection diagram of a coupler block and a distance adjusting mechanism provided in the embodiment.
As shown in fig. 1 and 2, the present embodiment provides a coupling including a first coupling block 1 fixedly connectable to a driving member, a second coupling block 2 fixedly connectable to a driven member, and a spacing adjustment mechanism 3 for connecting the first coupling block 1 and the second coupling block 2 in a spacing-adjustable manner. In this embodiment, the driving member and the driven member may be two shafts or a shaft and a rotating member (e.g., a gear, a pulley, etc.), respectively, for example, the driving member may be a driving shaft of an air cylinder, and the driven member may be a driven shaft driven to rotate by the air cylinder. The split setting of shaft coupling is realized through first shaft coupling piece 1 and second shaft coupling piece 2, because the interval between first shaft coupling piece 1 and second shaft coupling piece 2 is adjustable, consequently, after first shaft coupling piece 1 and drive member fixed connection, and second shaft coupling piece 2 and driven member fixed connection, through adjusting the interval between first shaft coupling piece 1 and second shaft coupling piece 2, can the interval between synchronous regulation drive member and the driven member, this process makes when using shaft coupling hookup drive member and driven member, the interval between drive member and the driven member is adjustable, can carry out nimble adjustment to the interval between drive member and the driven member based on the in-service use demand.
The device or mechanism that can adjust the interval between first coupling piece and the second coupling piece is more, for example, shortens or extends through drive arrangement drive telescopic link, and the telescopic link both ends are respectively in the butt of first coupling piece 1 and second coupling piece 2, through the shortening or the extension of telescopic link for interval is adjustable between first coupling piece and the second coupling piece. In the present embodiment, the above-described distance adjusting mechanism 3 includes an adjusting portion 31 and a locking portion 32, the adjusting portion 31 is used for adjusting the distance between the first coupling block 1 and the second coupling block 2, and the locking portion 32 is used for locking the adjusting portion 31 after the first coupling block 1 and the second coupling block 2 are adjusted to a predetermined distance. In the present embodiment, as shown in fig. 1, the adjusting portion 31 includes a first connecting portion 311 adjustably connected to the first coupling block 1, a second connecting portion 312 adjustably connected to the second coupling block 2, an adjustment triggering portion 313 for moving the first and second connecting portions 311 and 312, and a locking connecting portion 314 cooperating with the locking portion 32 to lock the first and second connecting portions 311 and 312.
The first coupling block 1 and the second coupling block 2 are connected in a manner of adjusting the distance, which may specifically be: when the adjustment trigger 313 is adjusted to move in the first manner, the first coupling block 1 and the second coupling block 2 are apart, or when the adjustment trigger 313 is adjusted to move in the second manner, the first coupling block 1 and the second coupling block 2 are close. That is, when the adjustment trigger 313 moves in two different ways, the first coupling block and the second coupling block can be moved closer to or farther from each other in synchronization. Taking the first coupling block 1 and the second coupling block 2 as an example of screw-locking, the first connecting portion 311 may be a first bolt having a positive screw structure, the second connecting portion 312 may be a second bolt having a negative screw structure, the first coupling block 1 includes a screw hole matching with the first bolt, the second coupling block 2 includes a screw hole matching with the second bolt, the adjusting trigger portion 313 is located between the first bolt and the second bolt, and the adjusting trigger portion 313, the first bolt and the second bolt are fixedly connected or integrally arranged in a manner corresponding to the same axis, in this case, when the adjusting trigger portion 313 rotates clockwise, the first bolt and the second bolt both rotate clockwise, and because the first bolt has a positive screw structure and the second bolt has a negative screw structure, under the action of the screw hole of the first coupling block 1 and the screw hole of the second coupling block 2, the first coupling block 1 and the second coupling block 2 are far away from each other; on the contrary, when the adjusting trigger part 313 rotates counterclockwise, the first bolt and the second bolt both rotate counterclockwise correspondingly, and the first coupling block and the second coupling block are close to each other under the action of the threaded hole of the first coupling block and the threaded hole of the second coupling block.

That is, when the wheel-like structure rotates one rotation unit every time, the moving distance between the first coupling block 1 and the second coupling block 2 corresponds to one distance unit. For example, assuming that the circumference of the wheel-shaped structure is uniformly divided into n rotation units and the pitch of the first bolt and the second bolt is I, the preset distance unit between the first coupling block and the second coupling block is L =2 × L × n/360. Through this kind of setting, the accurate distance of adjusting between first shaft coupling piece and the second shaft coupling piece of the mode of accessible rotation regulation trigger part for the regulation distance between first shaft coupling piece and the second shaft coupling piece is accurate controllable. Also, in the present embodiment, the maximum adjustable range of the distance between the first coupling block and the second coupling block may be defined by the following formula: s = (h-x) × 2, as shown in fig. 3, h is the thread coverage length of the first bolt or the second bolt, which characterizes the bolt adjustable length, and x is the critical safety locking distance between the first bolt and the first coupling block, or the critical safety locking distance between the second bolt and the second coupling block (the minimum distance that enables the bolt and the coupling block to maintain the connection state).
In this embodiment, the locking connection portion 314 may be a gear tooth uniformly distributed on the periphery of the wheel-shaped structure, each gear tooth corresponds to the rotation unit, the n rotation units represent n gear teeth, and when the rotation adjustment trigger portion is rotated, the distance between the first coupling block 1 and the second coupling block 2 may be accurately controlled by controlling the number of the rotation gear teeth. In this case, the locking portion is a locking member that can be locked to the gear teeth to stop the rotation of the wheel-shaped structure. This joint component can be the elasticity jump ring that both ends were fixed respectively and are set up in first coupling piece 1 and second coupling piece 2, and this elasticity jump ring can be after adjusting the distance between first coupling piece 1 and the second coupling piece 2, through the effective locking wheel-shaped structure of the mode of the teeth of a cogwheel of joint in wheel-shaped structure periphery for distance between first coupling piece 1 and the second coupling piece 2 keeps stable.
