Description
Technical field
The utility model belongs to the technical field of piece-holder.
Background technology
Interior clamping device refers to the device being fixed workpiece by holding workpiece inside, and the form parts such as with dovetail furrow just usually adopts the interior mode clamped.
When clamping the workpiece with dovetail furrow, normally by the outside of jaw, dovetail furrow two side is clamped.But as when carrying, jaw deflects, and the bare terminal of jaw is not be close to dovetail furrow two side, but when being in the position of dovetail furrow notch, workpiece will drop from interior clamping device.Workpiece is easily damaged, if dropped from eminence, also easily to be injured by a crashing object by operating personal, causes safety misadventure.
Utility model content
The utility model provides clamping device in a kind of dovetail furrow, to solve jaw easily from the problem that dovetail furrow notch departs from.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: clamping device in a kind of dovetail furrow, comprise frame and be connected to two main folder pawls in frame, hinged between two main folder pawls, also comprise adjust bar, two expansion links and two sub-folder pawls, the outside of main folder pawl is provided with support plate, expansion link comprise two thread rods and and the sleeve that is connected between two thread rods, expansion link is parallel with the bare terminal of main folder pawl, one end of expansion link is connected on support plate, the other end and sub-folder pawl hinged, adjust bar has several adjustment hole, the bare terminal of two main folder pawls has the mounting hole mated with adjustment hole size.
Principle of the present utility model is: when needing to clamp the dovetail furrow on workpiece, is close in the outside of main folder pawl bare terminal and the sidewall of dovetail furrow, and adjustable telescopic rod, expansion link is extended.Because expansion link is parallel with the bare terminal of main folder pawl, therefore outside the extended main folder pawl of expansion link, expansion link can drive sub-folder pawl to stretch out, sub-folder pawl can be close to the surface outside dovetail furrow, such clamping device is a just many face and absorption surface, main folder pawl is retrained, between workpiece and main folder pawl, just not easily relative rotation occurs.
Compared with prior art, the utility model has the advantage of: workpiece pushes against by the gravity of workpiece self by main folder pawl, by expansion link, sub-folder pawl is stretched out, offset, further by Workpiece clamping with the surface of workpiece.The utility model have employed the mode all clamped up and down, just not easily relative rotation occurs between workpiece and main folder pawl, workpiece not easily drops from the utility model, decreases the damage of workpiece, prevent workpiece to drop staff injured by a crashing object, ensure that the safety of operating personal.
Further, the drive end of main folder pawl is provided with extension spring, and the bare terminal making main folder pawl on condition that an external force is not applied, is in the state of opening, thus pushes against with the sidewall of dovetail furrow.
Further, sub-folder pawl is provided with sucker, and when expansion link extends, the adsorption of workpiece is lived by sucker, prevents sub-folder pawl from the surperficial landing of workpiece.
Further, the outside of main folder pawl bare terminal is provided with rubber layer, and the parts because of jaw class often adopt the material of metal, easily by workpiece mill flower, adopts quality of rubber materials, can play certain protective effect to the inwall of workpiece.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is the structural representation of clamping mechanism embodiment in the utility model dovetail furrow.
Detailed description of the invention
Reference numeral in Figure of description comprises: frame 1, main folder pawl 2, adjust bar 3, sub-folder pawl 4, thread rod 5, sleeve 6, adjustment hole 7, support plate 8.
As shown in Figure 1, clamping device in the dovetail furrow in the present embodiment, comprises frame 1, the two main folder pawls 2 be connected in frame 1, adjust bar 3, two expansion link and two sub-folder pawls 4.The middle part of one main folder pawl 2 and the middle part of another main folder pawl 2 hinged, the outside of main folder pawl 2 is provided with outwardly directed support plate 8, and the drive end of main folder pawl 2 is provided with extension spring, and the outside of main folder pawl 2 bare terminal is provided with rubber layer.Expansion link comprise two thread rods 5 and and the sleeve 6 that is connected between two thread rods 5, rotate forward sleeve 6, two thread rods 5 can stretch out in sleeve 6, and the total length of expansion link can be elongated; Rotate backward sleeve 6, two thread rods 5 can stretch in sleeve 6, and the total length of expansion link can shorten.Expansion link is parallel with the bare terminal of main folder pawl 2, and the upper end of expansion link is connected on support plate 8, lower end and sub-folder pawl 4 hinged, sub-folder pawl 4 is provided with sucker.Bare terminal adjust bar 3 having six adjustment holes 7, two main folder pawl 2 has the mounting hole mated with adjustment hole 7 size.
The use procedure of the present embodiment is as follows, pulls down adjust bar 3 from mounting hole, and operating personal pulls out the drive end of main folder pawl 2 with two, makes the bare terminal of main folder pawl 2 temporarily be in closed state, facilitates the bare terminal of main folder pawl 2 to stretch into from the notch of dovetail furrow.After main folder pawl 2 stretches into dovetail furrow, adjustment main folder pawl 2, the sidewall of main folder pawl 2 bare terminal and dovetail furrow is offseted, and main folder pawl 2 bare terminal under the effect of tension spring, can be close to the sidewall of dovetail furrow.At this moment, adjust bar 3 can be fixed on (employing bolted) on the mounting hole of main folder pawl 2 bare terminal by adjustment hole 7, it is to be particularly noted that need to select suitable adjustment hole 7 to be connected with mounting hole, to ensure that the opening dimension of jaw is greater than the notch place size of dovetail furrow.Rotate forward two sleeves 6 more successively, thread rod 5 is stretched out in sleeve 6, and expansion link can extend.Because expansion link is parallel with the bare terminal of main folder pawl 2, therefore outside the extended main folder pawl 2 of expansion link, expansion link can drive sub-folder pawl 4 to stretch out, and sub-folder pawl 4 can be close to the surface outside dovetail furrow, and the surface of workpiece can adsorb by sucker on sub-folder pawl 4 comparatively securely.
When workpiece is moved to destination locations, operating personal can be buckled with the edge of hand by sucker, air is made to enter sucker, rotate backward sleeve 6 again, expansion link is shortened, and adjust bar 3 gradually away from workpiece, then can draw off from mounting hole by sub-folder pawl 4, finally pull out the drive end of main folder pawl 2 with two, workpiece can be drawn off.
The drive end of main folder pawl 2 is provided with extension spring, and the bare terminal making main folder pawl 2 on condition that an external force is not applied, is in the state of opening, thus pushes against with the sidewall of dovetail furrow.Sub-folder pawl 4 is provided with sucker, and when expansion link extends, the adsorption of workpiece is lived by sucker, prevents sub-folder pawl 4 from the surperficial landing of workpiece.The outside of main folder pawl 2 bare terminal is provided with rubber layer, and the parts because of jaw class often adopt the material of metal, easily by workpiece mill flower, adopts quality of rubber materials, can play certain protective effect to the inwall of workpiece.
The utility model have employed the mode all clamped up and down, just not easily relative rotation occurs between workpiece and main folder pawl 2, workpiece not easily drops from the utility model, decreases the damage of workpiece, prevent workpiece to drop staff injured by a crashing object, ensure that the safety of operating personal.
For a person skilled in the art; under the prerequisite not departing from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
