Detailed Description

In order to explain technical contents and structural features of the present invention in detail, the following description is made with reference to the embodiments and the accompanying drawings.

Referring to fig. 1 to 4, a pneumatic tooling fixture 100 of the present invention includes a base 1, a shaft center 2, a housing 3, a shaft sleeve 4 and balls 5. The base 1 is provided with an air hole 11 for air to enter, the air inlet end of the air hole 11 is formed at the outer side of the base 1, and the air inlet end of the air hole 11 can be provided with an air pipe joint so as to be connected with an external air pump, and particularly, the base 1 is in a T shape; the axial core member 2 is connected to the base 1, the axial core member 2 has an insertion hole 21 communicated with the outside, a through hole 22 communicated with the insertion hole 21 is formed in a side wall of the axial core member 2, specifically, the insertion hole 21 penetrates through the axial core member 2, and the base 1 is provided with a through hole 12 communicated with the insertion hole 21, so that workpieces 200 with different lengths can be inserted into the insertion hole 21, but the invention is not limited thereto; the outer shell 3 is fixed on the base 1 and sleeved outside the axle center piece 2, specifically, the upper part of the outer shell 3 is provided with a connecting hole 31, and the upper end of the axle center piece 2 is inserted into the connecting hole 31; the base 1, the axle center piece 2 and the shell 3 are surrounded by an installation space 6, the balls 5 are movably arranged in the through holes 22, the shaft sleeve 4 is arranged in the installation space 6 and positioned above the air outlet end of the air hole 11, and the shaft sleeve 4 is sleeved outside the axle center piece 2 in a manner of sliding up and down; the ball 5 is pushed by the sleeve 4 to protrude into the insertion hole 21 and clamp the workpiece 200 in the insertion hole 21, or the external air enters the air hole 11 to push the sleeve 4 to slide upwards, so as to release the ball 5. Initially, the sleeve 4 is carried on the base 1 and abuts against the ball 5, so that the ball 5 protrudes into the insertion hole 21 and clamps the workpiece 200 in the insertion hole 21. When the workpiece 200 needs to be taken out, the external air pump supplies air to the air hole 11, so that external air enters the air hole 11 to push the shaft sleeve 4 to slide upwards, the shaft sleeve 4 does not abut against the ball 5, the ball 5 is loosened and does not clamp the workpiece 200 any more, and the workpiece 200 is convenient to take out. After the external air pump is disconnected to supply air to the air hole 11, the shaft sleeve 4 slides downwards and pushes against the ball 5 again, so that the ball 5 protrudes to the insertion hole 21 and clamps the workpiece 200 positioned in the insertion hole 21.

Referring to fig. 4 and 5, in the present embodiment, a plurality of through holes 22 are distributed on the sidewall of the shaft member 2 along the circumferential direction of the shaft member 2, and each through hole 22 is provided with a ball 5. By providing a plurality of balls 5, the workpiece 200 is clamped more firmly. The inner side of the sleeve 4 is provided with a slope 41 for pushing or releasing the ball 5. By driving the shaft sleeve 4 to slide upwards, the shaft sleeve 4 releases the balls 5 through the inclined surface 41 and no longer abuts against the balls 5, and by driving the shaft sleeve 4 to slide downwards, the shaft sleeve 4 abuts against the balls 5 through the inclined surface 41, so that the shaft sleeve 4 finally abuts against the balls 5 to extend out of the insertion holes 21. The inner side of the sleeve 4 may be provided with a chute having the inclined surface 41, but not limited thereto. Specifically, but not limited to, gaskets are respectively disposed between the shaft sleeve 4 and the base 1 and between the shaft sleeve 4 and the housing 3.

Referring to fig. 4, in the present embodiment, the pneumatic tooling fixture 100 further includes an elastic member 7 for restoring the shaft sleeve 4, and the elastic member 7 is disposed between the shaft sleeve 4 and the housing 3 along the sliding direction of the shaft sleeve 4. When an external air pump supplies air to the air hole 11, the air pushes the shaft sleeve 4 to slide upwards and compress the elastic piece 7. After the external air pump is disconnected to supply air to the air hole 11, the shaft sleeve 4 can slide downwards to reset under the action of the elastic restoring force of the elastic piece 7. But not limited to this, for example, the sleeve 4 may slide downward under its own weight. Specifically, the shaft sleeve 4 is provided with a plurality of slots 42, and a plurality of elastic members 7 are respectively inserted into the slots 42.

Referring to fig. 1 and 4, in the present embodiment, the pneumatic tooling fixture 100 further includes a carrier 8 for carrying the workpiece 200, the carrier 8 is inserted into the insertion hole 21, and a groove 81 for the ball 5 to extend into and clamp is formed on a side wall of the carrier 8. The carrier 8 is provided with a mounting hole for mounting the workpiece 200, in which the workpiece 200 is positioned by insertion. The workpiece 200 is clamped and positioned by driving the balls 5 to project into the insertion holes 21 and clamping the grooves 81 of the carrier 8.

Referring to fig. 6, in another embodiment, the difference is: the base 1 of the pneumatic tool clamp 100 is flat in structure. Due to the different shape and structure of the base 1, the clamping and positioning directions of the workpiece 200 are different, so that the machine can be used for processing different surfaces of the workpiece 200.

With reference to fig. 1 to 6, the pneumatic tool clamp 100 of the present invention has the following specific working principle:

initially, the sleeve 4 is carried on the base 1 and abuts the balls 5 such that the balls 5 project into the receptacles 21 and grip the carrier 8 loaded with the workpiece 200. When the workpiece 200 needs to be taken out, the external air pump supplies air to the air hole 11, so that the external air enters the air hole 11 to push the shaft sleeve 4 to slide upwards and compress the elastic piece 7, the shaft sleeve 4 does not abut against the ball 5, the ball 5 is loosened and does not clamp the workpiece 200, and the workpiece 200 can be taken out. After the air pump is disconnected from the outside to supply air to the air hole 11, the shaft sleeve 4 slides downwards under the elastic restoring force of the elastic piece 7 and is propped against the ball 5 again, so that the ball 5 protrudes to the insertion hole 21 and clamps the carrier 8 loaded with the workpiece 200.

To sum up, the pneumatic tool clamp 100 of the present invention abuts against the balls 5 through the shaft sleeve 4, so that the balls 5 clamp the workpiece 200 located in the insertion hole 21, and the external air enters the air holes 11, pushes the shaft sleeve 4 to slide upwards by the external air, so as to release the balls 5, and the balls 5 are loosened, so that the workpiece 200 located in the insertion hole 21 can be taken out; the utility model discloses a pneumatic frock clamp 100 can regard as frame quick change main part, realizes the outer clamping of machine, replaces current manual vice clamping, saves adjustment time, shortens the regulation and prepares the cycle, reduces the operation degree of difficulty to can improve production efficiency, and the preparation is convenient, low in production cost.
