Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-4, a pneumatic clamping jaw, including mounting panel 1, mounting panel 1 bottom fixedly connected with four fixed blocks 3, four fixed block 3 other ends all articulate there is clamping jaw 4, clamping jaw 4 one side fixedly connected with solid fixed ring 14, gu fixedly connected with on the fixed ring 14 connects rope 16, connect 16 other end fixedly connected with inserted bar 15 of rope, be equipped with claw 13 in the clamping jaw 4, fixedly connected with cylinder 2 on mounting panel 1, cylinder 2 is prior art, do not state here much, cylinder 2 output end fixedly connected with connecting plate 5 No. one, four sides of connecting plate 5 all articulate there is bracing piece 6 No. one, connecting plate 5 bottom fixedly connected with sleeve 7 No. one, sliding connection has slide bar 8 in sleeve 7, slide bar 8 bottom fixedly connected with connecting plate 9 No. two, sleeve 7 surface cover is equipped with spring 10.

Further, as can be seen from fig. 3 and 4, the jaw 4 is provided with a groove 11, and the groove 11 corresponds to a claw head 13, the claw head 13 slides in the groove 11, and the groove 11 is provided with damping rubber, which is not shown in the figure.

Further, referring to fig. 3, it can be known that the two sides of the groove 11 and the claw head 13 are provided with insertion holes 17, and the insertion holes 17 correspond to the insertion rods 15, and the two ends of the insertion rods 15 pass through the insertion holes 17 and extend out of the insertion rods.

Further, as can be known by referring to fig. 1 and 4, four first support rods 6 and four second support rods 12 respectively correspond to one clamping jaw 4, and the other ends of the first support rods 6 and the second support rods 12 are hinged to one side of the clamping jaw 4.

Further, as can be known from fig. 1, two ends of the spring 10 are respectively and fixedly connected to the bottom of the first connecting plate 5 and the top of the second connecting plate 9, and the four first supporting rods 6 are respectively aligned with the second supporting rod 12 up and down.

The scheme has the following working processes: control cylinder 2's output reciprocates during the use, thereby drive connecting plate 5 and remove, and connecting plate 5 removes the one end that can stimulate bracing piece 6 and removes, thereby make clamping jaw 4 rotate, and spring 10 is to the ascending pulling force of connecting plate 9 No. two, make connecting plate 9 up remove, and No. two connecting plate 9 remove can stimulate bracing piece 12 No. two, bracing piece 12 can stimulate clamping jaw 4 No. two, because the angle of clamping jaw 4 receives the restriction of bracing piece 6 No. two, consequently No. two bracing pieces 12 can not change the angle of clamping jaw 4, but can increase clamping jaw 4's clamping-force, thereby prevent clamping jaw 4's clamping-force too little and can not live the work piece.

Because the claw head 13 can also affect the clamping of the clamping jaw 4, the claw head 13 which is not fit for the workpiece can cause unstable workpiece clamping, so the claw head 13 needs to be replaced according to the workpiece, when the claw head 13 is replaced, only the inserting rod 15 needs to be drawn out, a new claw head 13 is inserted into the groove 11, the inserting holes 17 on the groove 11 and the claw head 13 are aligned, and then the inserting rod 15 is inserted.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
