Referring to fig. 1 to 10, an embodiment of the present invention provides a connecting assembly including a stationary member 100 and a movable member 200, the stationary member 100 having a first mating surface 110; a first tooth groove 111 engaged with the timing belt 300 is formed on the first mating surface 110 along the length direction thereof; the moveable member 200 is used to mount a load; the movable member 200 is connected to the stationary member 100 to be adjustable in position along the length of the first engagement surface 110, and the minimum displacement of the movable member 200 with respect to the stationary member 100 is smaller than the pitch of the first spline 111.
During installation: first, the first fitting surface 110 of the fixing member 100 is directed to the inside of the timing belt 300 so that the first tooth grooves 111 of the first fitting surface 110 are engaged with the tooth grooves of the timing belt 300. Next, the movable element 200 is fastened to the fixed element 100 from the outside of the timing belt 300, and the timing belt 300 is just clamped between the first mating surface 110 of the fixed element 100 and the movable element 200.
During adjustment: if fine adjustment is required, the movable element 200 is moved along the length direction of the first engagement surface 110 by a predetermined displacement relative to the fixed element 100. To perform rough adjustment, the movable element 200 may be detached from the stationary element 100, the stationary element 100 may be moved in the longitudinal direction of the timing belt 300 to perform a predetermined positional displacement, and then the movable element 200 may be newly attached to the stationary element 100.
It should be noted that the fine adjustment can be achieved by a variety of ways to adjust the position of the moveable member 200 relative to the stationary member 100, such as:
as shown in fig. 5, 6, 9 and 10, the fixing member 100 further has a second engagement surface 120, a second slot 121 is formed on the second engagement surface 120 along the length direction of the first engagement surface 110, and the pitch of the second slot 121 is smaller than the pitch of the first slot 111; the movable member 200 is formed with a third spline 210 engaged with the second spline 121. The included angle between the second mating surface 120 and the first mating surface 110 may be, but is not limited to, 90 °.
In this case, as shown in fig. 5 and 6, the second engagement surface 120 is provided with a first locking portion, and the first side of the movable member 200 is provided with a second locking portion for engaging with the first locking portion through a locking member to lock the first side of the movable member 200 to the stationary member 100; one side of the first mating surface 110 facing away from the second mating surface 120 is provided with a first limiting portion, the second side of the movable element 200 is formed with a limiting plate 230 extending toward the first limiting portion, the limiting plate 230 is provided with a second limiting portion, and the second limiting portion is used for being matched with the first limiting portion to limit the second side of the movable element 200 to move toward the direction facing away from the fixed element 100. The first locking portion is a first bar-shaped hole 112, the second locking portion is a threaded hole 220, the locking member is a screw 400, and of course, the first locking portion may also be a threaded hole 220, the second locking portion is a first bar-shaped hole 112, and the length direction of the first bar-shaped hole 112 is parallel to the length direction of the first matching surface 110; the first position-limiting portion is a protrusion 130, the second position-limiting portion is a second strip-shaped hole 240, the length direction of the second strip-shaped hole 240 is parallel to the length direction of the first matching surface 110, and the protrusion 130 is slidably inserted into the second strip-shaped hole 240.
Taking fig. 2 and 4 as an example, the timing belt 300 extends in the vertical direction, and the tooth grooves of the timing belt 300 face the left side:
during installation: first, the first fitting surface 110 of the fixing member 100 is directed to the right side, and the fixing member 100 is fastened to the timing belt 300 from the left side of the timing belt 300 such that the first tooth grooves 111 of the first fitting surface 110 are engaged with the tooth grooves of the timing belt 300. Then, the movable element 200 is fastened to the fixed element 100 from the front side of the synchronous belt 300, so that the protrusion 130 is inserted into the second bar-shaped hole 240, and the second tooth groove 121 is engaged with the third tooth groove 210; finally, the screw 400 is screwed into the threaded hole 220 through the first strip-shaped hole 112. At this time, the moveable member 200 cannot move in a direction away from the stationary member 100 under the restriction of the protrusion 130 and the screw 400, and the timing belt 300 is exactly clamped between the first mating surface 110 of the stationary member 100 and the moveable member 200.
Thus, when fine adjustment is required, first the screw 400 is unscrewed, that is, the screw 400 is unscrewed a short length from the threaded hole 220; then, the movable member 200 is moved forward until the restriction of the second tooth groove 121 on the third tooth groove 210 is released; since the length directions of the first bar-shaped hole 112 and the second bar-shaped hole 240 are both parallel to the length direction of the first mating surface 110, the movable element 200 can be directly moved along the length direction of the first mating surface 110, i.e., the up-down direction, until the displacement of the movable element 200 relative to the second mating surface 120 is an integral multiple of the pitch of the second tooth space 121. In the process, the screw 400 moves along the length direction of the first bar-shaped hole 112, and the second bar-shaped hole 240 moves relative to the protrusion 130. Next, the movable member 200 is moved backward until the third tooth groove 210 is re-engaged with the second tooth groove 121. Finally, the screw 400 is tightened to lock the first side of the moveable member 200 to the stationary member 100. At this time, the movable member 200 cannot move in a direction away from the stationary member 100 under the restriction of the protrusion 130 and the screw 400.
Of course, in order to further reduce the length of the first strip-shaped hole 112, i.e. the length of the fixing member 100, the number of the threaded holes 220 may be plural. For example, the number of the screw holes 220 is two. As shown in fig. 1, taking the screw 400 screwed into the upper threaded hole 220 as an example, when the movable element 200 moves upward a certain distance relative to the fixed element 100, the screw 400 is blocked by the top surface of the inner wall of the first strip-shaped hole 112 and cannot move upward, and if the movable element 200 needs to move upward, the screw 400 can be screwed out of the threaded hole 220 and screwed into the lower threaded hole 220. At this time, there is a certain distance between the threaded hole 220 and the top surface of the inner wall of the first bar-shaped hole 112, and the screw 400 can continue to move along the first bar-shaped hole 112.
In addition to the above-described form, the first locking portion, the second locking portion, and the first position-limiting portion and the second position-limiting portion may be in other forms, for example:
as shown in fig. 7 to 10, a first locking portion is disposed on a side of the second engagement surface 120 opposite to the first engagement surface 110, a first limiting plate 231 extending toward the first locking portion is formed on the first side of the movable member 200, and a second locking portion is disposed on the first limiting plate 231 and is used for being buckled with the first locking portion to lock the first side of the movable member 200 to the fixed member 100; one side of the first mating surface 110 facing away from the second mating surface 120 is provided with a first limiting portion, the second side of the moving element 200 is formed with a second limiting plate 232 extending toward the first limiting portion, the second limiting plate 232 is provided with a second limiting portion, and the second limiting portion is used for being matched with the first limiting portion to limit the second side of the moving element 200 to move toward the direction facing away from the fixing element 100. As shown in fig. 9 and 10, the first locking portion is a first rib 140 extending along the length direction of the first mating surface 110, and the second locking portion is a second rib 250 for engaging with the first rib 140; the first position-limiting portion is a protrusion 130, the second position-limiting portion is a second strip-shaped hole 240, the length direction of the second strip-shaped hole 240 is parallel to the length direction of the first matching surface 110, and the protrusion 130 is slidably inserted into the second strip-shaped hole 240.
Taking fig. 7 and 8 as an example, the timing belt 300 extends in the vertical direction, and the tooth grooves of the timing belt 300 face the left side:
during installation: first, the first fitting surface 110 of the fixing member 100 is directed to the right side, and the fixing member 100 is fastened to the timing belt 300 from the left side of the timing belt 300 such that the first tooth grooves 111 of the first fitting surface 110 are engaged with the tooth grooves of the timing belt 300. Then, the movable element 200 is fastened to the fixing element 100 from the rear side of the timing belt 300, so that the protrusion 130 is inserted into the second strip-shaped hole 240, and the first protrusion strip 140 and the second protrusion strip 250 are fastened. At this time, the movable element 200 cannot move in a direction away from the fixed element 100 under the constraint of the protrusion 130 and the first protruding strip 140, and the timing belt 300 is just clamped between the first mating surface 110 of the fixed element 100 and the movable element 200.
Thus, when fine adjustment is required, the movable element 200 is moved backward until the restriction of the second tooth groove 121 on the third tooth groove 210 is released. Since the length directions of the first protruding strip 140 and the second strip-shaped hole 240 are both parallel to the length direction of the first mating surface 110, the movable element 200 can be directly moved along the length direction of the first mating surface 110 until the displacement of the movable element 200 relative to the second mating surface 120 is an integral multiple of the pitch of the second tooth groove 121. In the process, the second rib 250 moves relative to the first rib 140, and the second slot 240 moves relative to the protrusion 130. Next, the movable member 200 is moved forward until the third tooth groove 210 is re-engaged with the second tooth groove 121. At this time, the movable element 200 cannot move in a direction away from the stationary element 100 under the constraint of the protrusion 130 and the first protrusion 140.
It should be noted that, in order to reduce the engagement resistance between the first protruding strip 140 and the second protruding strip 250, a second inclined surface 251 is arranged on a side of the second protruding strip 250 facing away from the first limiting plate 231, and the first protruding strip 140 is formed with a first inclined surface 141 movably engaged with the second inclined surface 251.
In the second form, the fixing member 100 further has a second matching surface 120, a plurality of through holes are formed in the second matching surface 120 along the length direction of the first matching surface 110, and the distance between two adjacent through holes is smaller than the pitch of the first tooth grooves 111; the first side of the movable member 200 is formed with connection holes corresponding to the through holes one to one, and the through holes and the corresponding connection holes are used to install pins, so that the stationary member 100 is connected to the movable member 200. Wherein, a first locking portion is disposed on a side of the second matching surface 120 opposite to the first matching surface 110, a first limiting plate 231 extending towards the first locking portion is formed on the first side of the movable member 200, the first limiting plate 231 is provided with a second locking portion, and the second locking portion is used for being buckled with the first locking portion to lock the first side of the movable member 200 to the fixed member 100; one side of the first mating surface 110 facing away from the second mating surface 120 is provided with a first limiting portion, the second side of the moving element 200 is formed with a second limiting plate 232 extending toward the first limiting portion, the second limiting plate 232 is provided with a second limiting portion, and the second limiting portion is used for being matched with the first limiting portion to limit the second side of the moving element 200 to move toward the direction facing away from the fixing element 100. For example, the first locking portion is a first rib 140 extending along the length direction of the first mating surface 110, and the second locking portion is a second rib 250 for engaging with the first rib 140; the first position-limiting portion is a protrusion 130, the second position-limiting portion is a second strip-shaped hole 240, the length direction of the second strip-shaped hole 240 is parallel to the length direction of the first matching surface 110, and the protrusion 130 is slidably inserted into the second strip-shaped hole 240.
It should be noted that, the connection mode between the pin and the connection hole may be, but is not limited to, a snap connection or a threaded connection. Use the connecting hole as the screw hole, the tip of round pin post seted up with screw hole complex external screw thread as the example:
during fine adjustment: firstly, screwing the pin out of the threaded hole; since the length directions of the first protruding strip 140 and the second strip-shaped hole 240 are both parallel to the length direction of the first mating surface 110, the movable element 200 can be directly moved along the length direction of the first mating surface 110 until the displacement of the movable element 200 relative to the second mating surface 120 is an integral multiple of the distance between the two through holes; and finally, the pin columns penetrate through the corresponding through holes and then are screwed into the corresponding threaded holes. At this time, the movable element 200 cannot move in a direction away from the stationary element 100 under the constraint of the pin, the protrusion 130 and the first protrusion 140.
