The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, one end at holder 1 is fixedly mounted and is connected stock 2 by screw thread, connect on stock 2 connector 3 is installed, by this connector 3, caliper angle adjusting piece 4 is installed, and caliper angle adjusting piece 4 is fixedly connected with cylinder 6, by regulating caliper angle adjusting piece 4, change the angle that connects stock 2 and cylinder 6 axis.
As shown in Figures 2 and 3, expansion link 7 is installed on cylinder 6, by cylinder 6, is driven the flexible of expansion link 7.Above-mentioned expansion link 7 is at the interior moving telescopic of reducing sleeve 18, and the end of simultaneous retractable bar 7 is connected with one end of adapting rod 8 by bearing pin A14, and the other end of adapting rod 8 is connected with the lower end of lower clamp 17 by bearing pin C16.
The end of above-mentioned reducing sleeve 18 is connected with upper clamp 9, on upper clamp 9, bearing pin B15 is installed, and by bearing pin B15, is connected with the upper end of lower clamp 17.
As shown in Figure 2, when expansion link 7 is pulled by cylinder 6, left during rectilinear motion, because expansion link 7 is connected by bearing pin A14 axle with adapting rod 8, therefore pulling adapting rod 8 to rotate adapting rod 8 straight lines simultaneously around the position of bearing pin A14 moves to left, the now motion of adapting rod 8 is the compound motion that moves to left and be rotated counterclockwise, drive the lower clamp 17 being connected with adapting rod 8 axles to swing clockwise around bearing pin B15 simultaneously, because lower clamp 17 is connected by bearing pin B15 axle with upper clamp 9, therefore lower clamp 17 and upper clamp 9 open certain angle.Control the size that above-mentioned cylinder 6 pulls expansion link 7 to move to left, can control the opening angle of lower clamp 17 and upper clamp 9.
As shown in Figure 3, when expansion link 7 is pushed to the right by cylinder 6 drivings, expansion link 7 moving linearly to the right in reducing sleeve 18, adapting rod 8 is pushed and moves to right, because adapting rod 8 is connected with lower clamp 17 axles by bearing pin C16, lower clamp 17 is connected with upper clamp 9 axles by bearing pin B15 again, therefore lower clamp 17 is driven by adapting rod 8, can only upwards swing around the position of bearing pin B15, the movement locus that is the bearing pin C16 on adapting rod 8 is restricted to the circular motion around bearing pin B15 rotation, the now motion of adapting rod 8 is the compound motion that moves to right and turn clockwise, the motion that is rotated counterclockwise that drives lower clamp 17 to do around bearing pin B15, make lower clamp 17 and upper clamp 9 closures.
Fig. 4 is the partial schematic diagram of caliper angle adjusting piece part in Fig. 1, and the direction shown in Fig. 4 is the direction that top from Fig. 1 is seen vertical.
Described caliper angle adjusting piece 4 comprises eyelet bolt 21, rotary handle 22 and split pin 19.Eyelet bolt 21 upper ends are processed with movable joint ring, and rotary handle 22 is arranged in movable joint ring, and can in movable joint ring, move the turning arm length that regulates two ends.Cylinder 6 one sides are processed with suspension ring hole, and suspension ring hole extend in connector 3, and eyelet bolt 21 passes the suspension ring hole of cylinder 6, and is threaded with connector 3, and the suspension ring hole of cylinder 6 can turn to certain angle around eyelet bolt 21 like this.Split pin 19 is arranged on the bottom of eyelet bolt 21, is used for preventing that eyelet bolt 21 from screwing out and coming off from connector 3.Between the suspension ring hole of cylinder 6 and connector 3, place friction pad 20, during installation, eyelet bolt 21, simultaneously through friction pad 20, makes frictional force increase like this, and cylinder 6 can be kept reliably with the relative connection angle of connector 3.
Certainly, also the structure of connector 3 can be processed into integral body with being connected stock 2, the one end that connects stock 2 is sleeved on outside the suspension ring hole of cylinder 6, and eyelet bolt 21 is through the suspension ring hole of cylinder 6, and connection stock 2 is threaded.
When using, pneumatic pliers can coordinate journal stirrup jointly to use, journal stirrup is generally erected at connector 3 or connects the below of stock 2, in order to make journal stirrup, reliably install, on connector 3 or connection stock 2, process journal stirrup groove, journal stirrup passes through the reliable clamping cylinder suspension ring of journal stirrup groove, thereby further guarantees that cylinder 6 can be kept reliably with the relative connection angle of connector 3.
When caliper angle adjusting piece 4 is artificially regulated, conversion connects the angle of stock 2 and cylinder 6 axis, drives expansion link 7, adapting rod 8 and clamp to swing simultaneously, thereby makes clamp approach object with best angle.Meanwhile, cylinder 6 is controlled again the flexible of expansion link 7, thereby changes the position that moves axially of clamp, with most suitable distance, approaches by the object of gripping.
For the adjusting of caliper angle adjusting piece 4 is controlled, the folding angle of the air inlet of control cylinder 6 simultaneously and then control clamp is installed and is controlled hand valve 10 on holder 1, and the control tracheae 13 of controlling on hand valve 10 is communicated with cylinder 6 by joint 5.And the inlet suction port 12 of above-mentioned control hand valve 10 connects gas source pipe 11, by this structure air inlet.
When having gripping object, by connecting stock 2, pneumatic pliers is moved near object, hand valve 10 is controlled in rotation opens 9 mouthfuls of clamps, and jaw end extends object outside, and hand valve 10 is controlled in rotation remains silent clamp 9, gripping object, by connecting stock 2, pneumatic pliers is moved to the place (as collection container mouth) of expection, hand valve 10 is controlled in rotation, and clamp 9 and lower clamp 17 are opened, discharge object, complete once the removing of microscler hard foreign matter.
