Detailed ways

Referring to the accompanying drawings, through the description of the embodiments, the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the function and working principle of each part, and the manufacturing process And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

The structure of the present invention as shown in Fig. 1, Fig. 2 and Fig. 3, the present invention is a corrugated hose press-fit chuck, including a press joint 8. The press joint 8 is tightly connected with the press through the handle portion thereon.

In order to solve the problems existing in the current known technology described in the background technology part of this specification and overcome its defects, and realize the invention purpose of the crimping assembly of the corrugated hose, the technical solution adopted by the present invention is as follows:

The corrugated hose press-fit chuck provided by the present invention, the press-fit chuck is provided with a clamping block 2 and a clamping block 3, the described press-fit chuck is provided with an eccentric clamping mechanism, and the described eccentric clamp The clamping mechanism clamps the corrugated hose 9 through the clamping block 2 and the clamping block 3. The shape of the part of the clamping block 2 and the clamping block 3 clamping the corrugated hose 9 is consistent The shape of the corrugated hose 9 is adapted.

The present invention clamps the corrugated hose 9 with a clamping profiling mouth, which not only ensures that the corrugated hose 9 is not deformed, but also ensures that the corrugated hose 9 can withstand sufficient pressing force. The eccentric clamping mechanism is adopted, which is easy to operate, fast in clamping action and high in production efficiency.

The eccentric clamping mechanism of the present invention is provided with a clamping cam 1, and a clamping handle 5 is provided on the clamping cam 1, and the clamping cam 1 is connected with the clamping block 2, One of the clamping blocks 3 is connected, and the edge of the clamping cam 1 is in contact with the other clamping block.

The clamping and opening are controlled by the cam 1, the structure is simple and the operation is convenient.

The clamping cam 1 of the present invention is connected with the clamping pull rod 4 using a cam turning pin 7 . The cam 1 and the clamping rod 4 form a relative rotary motion to ensure the linear motion of the clamping rod 4 and realize the relative motion of the clamping block 2 and the clamping block 3 .

The lower part of the press joint 8 according to the present invention is provided with a downward rectangular protrusion, and two clamping block guide posts 10 are arranged on the rectangular protrusion and are tightly connected with the rectangular protrusion. Both ends protrude from the rectangular protrusion, and its direction is parallel to the clamping rod 4. The clamping block 2 and the clamping block 3 are connected to the clamping block guide post 10 through the holes. Both ends protrude to form a clearance fit.

The effect of clamping block guide post 10 is to limit the motion track of clamping block 2, clamping block 3, guarantees the accuracy of clamping block 2, clamping block 3 motion tracks.

A spring 6 is provided between the clamping block and the rectangular protrusion in the present invention, and the spring 6 is a compression spring, and is sleeved on the guide column 10 of the clamping block.

The above-mentioned clamping block 2 and clamping block 3 use two sets of spring mechanisms respectively, so that the collet can be opened to both sides at the same time.

In order to prevent the clamping block guide post 10 from loosening and falling off, the clamping block guide post 10 of the present invention is tightly connected to the rectangular protrusion through the guide post fixing screw 12 provided on the press joint 8 .

The use operation method of the present invention:

Rotate the clamping handle 5 by hand to rotate the cam 1 to the loosened position. At this time, the clamping block 2 and the clamping block 3 are opened to the maximum under the action of the spring 6 .

The corrugated hose 9 is put into the mouth of the clamping block 2 and the clamping block 3 which are adapted to the shape of the corrugated hose 9 . Reversely rotate the clamping handle 5 to make the cam 1 turn to the clamping position. At this time, under the action of the clamping rod 4, the clamping block 2 and the clamping block 3 clamp the corrugated hose 9.

After starting the press machine and corrugated hose 9 is pressed in place, the pressing stroke of the press machine stops.

Rotate the clamping handle 5 to turn the cam 1 to the loose position, open the clamping block 2 and the clamping block 3, loosen the corrugated hose 9, and press the corrugated hose to press the collet back to its original position.
