Description
Technical field
The utility model belongs to fastening or the technical field of the device of fixed component or machine parts.
Background technology
Before processing workpiece, need workpiece to be fixed and to locate, prevent workpiece from moving in the process of processing.Now common workpiece grip mechanism is clamped by workpiece by two jaws be oppositely arranged, and provide lasting clamping force to be fixed by workpiece.
But adopt said structure to there is following drawback: arranging of jaw needs to design according to the shape of workpiece, otherwise is point cantact between jaw and workpiece, easily makes workpiece impaired.Need to provide special driving mechanism or manpower to make jaw have lasting clamping force to workpiece, ensure that workpiece can not fall down from jaw, but special driving mechanism and manpower clamping will certainly increase the cost of of clamping device itself.
Utility model content
The utility model provides a kind of gasbag-type hold down gag, needs to provide special driving mechanism or manpower to make workpiece by the problem continuing to clamp to solve.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of gasbag-type hold down gag, comprise base and be located at the pressing plate on base, the space holding workpiece is formed between base and pressing plate, also comprise air bag and be fixed on the round pin on base, one end of pressing plate is hinged on base, the other end of pressing plate is hinged with lockplate, lockplate is provided with the groove of one end open, the inwall of groove can contact with round pin, the inwall of groove has groove, catch is provided with in groove, stage clip is provided with between catch and groove, catch is an inclined-plane towards the one side of groove opening, inclined-plane tilts towards the direction away from groove opening, air bag is arranged on pressing plate towards on the side of workpiece.
Principle of the present utility model is: will be filled with appropriate gas in air bag, put into by workpiece between base and pressing plate, rotate pressing plate, pressing plate is detained, the air bag on pressing plate can gradually with absorption surface.When free end and the base contacts of pressing plate, workpiece is just in clamped state, and at this moment, twist-lock plate, makes the round pin on base slip in groove.When round pin contacts with catch, because inclined-plane tilts towards the direction away from groove opening, stage clip can be compressed, and catch can decline, and round pin will arrive the sealed end of groove, and round pin can block by the inclined-plane on catch, round pin is locked, thus is locked by pressing plate.
Compared with prior art, the utility model has the advantage of: 1, pressing plate is provided with air bag, by being filled with the gas of different amount in air bag, thus different workpiece being compressed, not needing to design different pressing plates according to different workpiece.2, pressing plate is provided with lockplate, is locked by pressing plate by lockplate, does not need special drive unit or manpower to provide clamping force, the utility model is compared with other clamping device cost lower.
Further, also comprise the air pump be arranged on base, the gas outlet of air pump is connected with the air inlet of air bag, can conveniently inflate the air bag on pressing plate, and an air pump may correspond to multiple air bag, and in other words, an air pump can be inflated multiple air bag.
Further, described pressing plate has through hole, be convenient to the workpiece with axle, such as gear shaft etc. clamp.
Further, the base holding workpiece space is provided with locating slot, can conveniently position the end face 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 the utility model gasbag-type hold down gag embodiment.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, pressing plate 2, air bag 3, round pin 4, lockplate 5, groove 6, locating slot 7, catch 8, air pump 9.
As shown in Figure 1, a kind of air bag 3 formula hold down gag in the present embodiment, comprises base 1, the pressing plate 2 be located on base 1, air bag 3 and the round pin 4 that is fixed on base 1.Form the space holding workpiece between base 1 and pressing plate 2, the upper surface of base 1 is provided with locating slot 7.Pressing plate 2 has through hole, and the left end of pressing plate 2 is hinged on base 1, the right-hand member of pressing plate 2 is hinged with lockplate 5.Lockplate 5 is provided with the groove 6 of one end open, and the inwall of groove 6 can contact with round pin 4, the inwall of groove 6 has groove, is provided with catch 8 in groove.Be provided with stage clip between catch 8 and groove, catch 8 is an inclined-plane towards the one side of groove 6 opening, and inclined-plane tilts towards the direction away from groove 6 opening, and air bag 3 is arranged on pressing plate 2 towards on the side of workpiece.Air pump 9 on base 1, the gas outlet of air pump 9 is connected with the air inlet of air bag 3.
Be filled with appropriate gas by air inlet by air bag 3, the one end because of pressing plate 2 is hinged on base 1, rotates pressing plate 2, pressing plate 2 is lifted, workpiece is put between base 1 and pressing plate 2, rotate pressing plate 2, pressing plate 2 is detained, air bag 3 on pressing plate 2 can gradually with absorption surface.When the free end of pressing plate 2 contacts with base 1, workpiece is just in clamped state, because air bag 3 can change along with workpiece shapes, therefore can not weigh workpiece wounded.At this moment, twist-lock plate 5, makes the round pin 4 on base 1 slip in groove 6 from the openend of groove 6.When round pin 4 contacts with catch 8, because inclined-plane tilts towards the direction away from groove 6 opening, catch 8 can be depressed along the inclined-plane of catch 8 by round pin 4, round pin 4 will cross the sealed end that catch 8 arrives groove 6, after round pin 4 crosses catch 8, catch 8 can be upspring under the effect of stage clip, and round pin 4 can block by the inclined-plane on catch 8, round pin 4 is locked, thus pressing plate 2 is locked.
When needs unlock, press lower stop piece 8 by external force, catch 8 can be depressed, twist-lock plate 5, and round pin 4 just can depart from groove 6, finally lifts pressing plate 2, just workpiece can be taken out.
Base 1 is provided with air pump 9, can conveniently inflates the air bag 3 on pressing plate 2, and an air pump 9 may correspond to multiple air bag 3, air pump 9 can inflate multiple air bag 3.Pressing plate 2 has through hole, and be convenient to the workpiece with axle, such as gear shaft etc. clamp.The upper surface of base 1 is provided with the locating slot 7 mated with workpiece end face, can conveniently position the end face of workpiece.
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.
