In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "middle", "lower", "inner", "outer", "front", "rear", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or component to be referred to must have a specific direction, be configured and operated in the specific direction, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art. Hereinafter, an embodiment of the present utility model will be described in terms of its overall structure.
Referring to fig. 1 to 5, the present utility model discloses a clamping mechanism for a narrow space, which includes:
a base block 1;
The fixed claw 2 is fixedly arranged on one side of the base block 1, and a chute is formed between the end surface of the fixed claw 2 facing the base block 1 and the end surface of the base block 1 facing the fixed claw 2;
A movable claw 3, wherein the movable claw 3 is provided with a main body part and a head part connected with the main body part, the main body part is in clearance fit with the chute, and the head part penetrates out of the chute;
The end face of the main body part facing the head part and the sliding groove are provided with a first damping piece 41, the end face of the main body part facing away from the head part is propped against the first end of a rotating piece 5, and the first end of the rotating piece 5 can rotate around a shaft under the driving of a driving component so that the main body part of the movable claw 3 slides relative to the sliding groove, and the head part of the movable claw 3 is driven to relatively approach/separate from the head part of the fixed claw 2 along the sliding direction of the main body part of the movable claw 3.
With the above structure, the main body of the movable claw 3 is clearance fit in the chute formed between the end face of the fixed claw 2 facing the base block 1 and the end face of the base block 1 facing the fixed claw 2, and the head of the movable claw 3 connected with the main body of the movable claw passes through the chute and is arranged opposite to the head of the fixed claw 2. Because the first damping member 41 is disposed between the end face of the main body portion of the movable claw 3 facing the head portion thereof and the sliding groove, the first end of the rotating member 5 abuts against the end face of the main body portion facing away from the head portion, so that when the head portion of the movable claw 3 needs to be relatively far away from the head portion of the fixed claw 2, that is, when the clamping mechanism for a small space is opened to clamp the material taking member 9, only the first end of the rotating member 5 needs to be driven by the driving assembly to rotate around the shaft, and therefore the main body portion of the movable claw 3 slides and pushes the first damping member 41 relative to the sliding groove to reach a preset deformation amount. When the material piece 9 is located between the two heads of the movable claw 3 and the fixed claw 2, the head of the movable claw 3 is required to be relatively close to the head of the fixed claw 2 to clamp the material piece 9, namely, the clamping mechanism is closed to clamp the material piece 9 in a narrow space, only the first end of the rotating piece 5 is required to be driven by the driving component to rotate reversely around the shaft, and due to the reset action of the first damping piece 41, the main body of the movable claw 3 can reversely slide relative to the sliding groove, so that the two heads can stably clamp the material piece 9 between the two parts, and the condition that the material piece 9 falls when being clamped and transported by the clamping mechanism in the narrow space is avoided. Since the first damping member 41 and the first end of the rotating member 5 are respectively disposed at two ends of the main body of the movable claw 3, when the main body slides in the chute, the force balance is always uniform, and the clamping injury between the two ends or the material 9 is avoided. In addition, the rotary piece 5 is adopted to conduct acting force on the movable claw 3, the straight line is changed into an arc line, the space of the straight line required by the clamping action of the two claw heads is small, the action space is concentrated, and the applicability is stronger.
Referring to fig. 1, 2 and 5, in particular, in this embodiment, the portion of the material 9 to be clamped is in a sheet shape. The base block 1 is formed by combining a plurality of split block structures, and is convenient for assembling the fixed claw 2, the fixed claw 2 and other inner edges. The fixed claw 2 is fixedly connected to the lower end face of the base block 1 by using a fastener, and the head part of the fixed claw protrudes leftwards out of the left end face of the base block 1. Referring to fig. 3 and 4, the middle of the lower end surface of the base block 1 is recessed to form a chute with the fixed jaw 2 for mounting the main body of the movable jaw 3. A first damping member 41 is disposed between the left end of the chute and the left end face of the upper portion of the main body of the movable claw 3 opposite to the left end of the chute, and the first end of the rotating member 5 of the base block 1 abuts against the right end face of the movable claw 3, so that when the rotating member 5 rotates around an axis, the main body of the movable claw 3 slides left and right in the chute, and the head extending leftwards out of the chute is driven to synchronously move leftwards or rightwards near the head of the fixed claw 2. Preferably, in order to maintain the overall stability of the clamping mechanism for a small space, the left end or the right end of the first damper 41 may be connected to the left groove wall of the opposite chute and the upper left end surface of the movable claw 3, respectively. It will be appreciated that the first damping member 41 is maintained in at least a slightly compressed state when the movable jaw 3 and the stationary jaw 2 are maintained in a state of clamping the material 9, which ensures the clamping effect without the heads of the jaws causing pinching damage to the material 9.
Specifically, in this embodiment, the rotating member 5 further includes a second end and a bending portion, where the bending portion is connected between the first end and the second end of the rotating member 5, so that the rotating member 5 is integrally in a horizontally placed hook shape, and the second end is located above the first end and is rotationally connected with the base block 1 through a pin shaft 7, and when driven by the driving component, the rotating member can rotate relative to the base block 1 with the pin shaft 7 as a center, so that the main body portion of the movable claw 3 abutting against the first end of the rotating member 5 can slide left and right in the chute.
Referring to fig. 1 and 3, in particular, in this embodiment, the driving assembly includes a driving source 61 and a push post 62; when the head of the movable claw 3 is required to be far left from the head of the fixed claw 2 to open the two claws, the pushing post 62 only needs to be pushed downwards by the output end of the driving source 61, and the pushing post 62 vertically moves downwards along the guide through hole in the base block 1, so as to drive the rotating member 5 to rotate clockwise, thereby pushing the main body of the movable claw 3, overcoming the friction force between the main body of the movable claw 3 and the sliding groove and the resistance of the first damping member 41, enabling the main body of the movable claw 3 to slide horizontally leftwards relative to the sliding groove, and simultaneously keeping the head of the two claws far left from the head of the fixed claw 2 at a constant speed, so that the heads of the two claws are opened to a preset distance to enable the clamping member 9 to be moved in. For example, in this embodiment, the maximum distance between the head of the movable claw 3 and the head of the fixed claw 2 is preset to be 2.0mm, that is, the gap between the two claws after being fully opened is set to be 2.0mm. It can be controlled by setting the descending length of the pushing post 62 driven by the driving source 61, and of course, in other embodiments, the gap after the two jaws are fully opened can be set to other values according to actual needs, so as to facilitate clamping the material taking part 9.
Referring to fig. 1, 4 and 5, specifically, when the material 9 is located in the gap between the two jaws that are fully opened, the output end of the driving source 61 cancels pushing the pushing post 62, the first damping member 41 automatically resets to the right due to its physical property, and the force of elastic rightwards resetting is sufficient to overcome the friction between the main body of the movable jaw 3 and the chute, and the component forces of the rotating member 5 and the pushing post 62 in the left-right direction, so that the head of the movable jaw 3 synchronously moves to the right along with the rightwards reset main body, and the head of the fixed jaw 2 cooperates with the head of the fixed jaw to stably clamp the material 9.
With continued reference to fig. 1 and 2, in particular, in this embodiment, the driving source 61 is a cylinder.
Specifically, in this embodiment, the base block 1 is connected to the first side wall of the stand 8, and the base block 1 is located between the head of the fixing claw 2 and the first side wall of the stand 8 in the left-right direction. The base block 1 is connected with a further drive device so as to be capable of sliding fit in the vertical direction with the first side wall of the stand 8 so as to be capable of transporting the material 9 held by the two clamping jaws in the vertical direction.
Specifically, in this embodiment, a fixing plate 81 is further installed on the upper portion of the first sidewall to mount the driving source 61, i.e. the cylinder.
Specifically, in this embodiment, a limiting protruding plate 82 is further disposed at an end of the stand 8 away from the fixing plate 81, and the base block 1 is located between the limiting protruding plate 82 and the fixing plate 81 in the vertical direction, that is, the sliding distance of the base block 1 relative to the first side wall in the vertical direction is determined by the distance between the limiting plate and the fixing plate 81. In addition, the positioning of the limiting convex plate 82 plays a supporting role on the base block 1 at the lowest height, for example, in this embodiment, when the base block 1 is preset to be at the lowest height, the two clamping jaws perform the clamping action of the material 9, and when the clamping action is performed, the lifting action on the base block 1 can be canceled by another driving device connected to the base block 1.
Specifically, in this embodiment, a second damping member 42 is further connected between the base block 1 and the end surface of the fixing plate 81 facing the base block 1, so that the base block 1 can be driven by a driving device that is further connected to perform buffering during sliding relative to the stand 8 in the vertical direction, thereby ensuring that the material 9 is stably clamped and does not fall during the transferring process.
Finally, it should be noted that: the foregoing description of the preferred embodiments of the present utility model is not intended to be limiting, but rather, although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any changes, equivalents, modifications and improvements may be made without departing from the spirit and principles of the present utility model.
