Detailed Description

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

Referring to fig. 1, in the abrasive flow treatment process of the corrugated pipe (metal hose 7), it is necessary to clamp both ends of the metal hose 7 by clamps, and then the abrasive flow 8 is processed in different pulse forms inside the metal hose 7 to remove the excess.

In order to improve stability and the efficiency of this type of course of working, refer to fig. 2, fig. 3 and fig. 4, the utility model provides a bellows clamping tool, press from both sides tight segmental arc structure 2 including the anchor clamps body 1 and a plurality of one end trompil, press from both sides tight segmental arc structure 2 movably and install the one end that the anchor clamps body 1 needs the centre gripping bellows, press from both sides the direction of motion of tight segmental arc structure 2 and be on a parallel with the cross section of anchor clamps body 1, when moving to the most be close to anchor clamps body 1 center, press from both sides tight segmental arc structure 2 and stretch into between two ripples of bellows, press from both sides the bellows tightly.

In the processing process, the corrugated pipe is firstly stretched into the open hole of the clamp body 1, and then the clamping arc-shaped structures 2 are pushed inwards until reaching the wave band sunken in the corrugated pipe, so that the corrugated pipe is clamped.

Specifically, the anchor clamps body 1 needs the one end of centre gripping bellows, and it has the protruding 101 of a plurality of segmental arc form to distribute, and the certain distance in interval forms the recess between the protruding 101 of adjacent segmental arc form, every press from both sides tight segmental arc structure 2 and install in the inboard of the protruding 101 of segmental arc form, press from both sides and be equipped with handle 201 on the tight segmental arc structure 2, handle 201 matches in the recess between two adjacent segmental arc form arch 101, in the protruding 101 of segmental arc form and the outside of pressing from both sides tight segmental arc structure 2, is provided with annular apron 3, at annular apron 3, handle 201 with be equipped with fixed subassembly on the corresponding position of the anchor clamps body 1 for will press from both sides tight segmental arc structure 2 and fix in different positions, the handle 201 is kept away from the one end that presss from both sides tight segmental arc structure 2 and.

When the clamping arc-shaped structure 2 is used, the fixing component is firstly released from the handle 201, the handle 201 is pushed downwards to slide along the groove, and after the target position is reached, the fixing component clamps the position of the handle 201 again, so that the position of the clamping arc-shaped structure 2 is fixed.

In order to fix and release the handle 201 conveniently, as the improvement, the fixed subassembly includes location nail 4 and spring 5, and location nail 4 passes annular apron 3 in proper order handle 201 with the anchor clamps body 1 to the annular apron 3 is close to the one side of handle 201, is equipped with the holding tank, and location nail 4 establishes and is equipped with annular arch, and spring 5 connects on the inner wall of annular arch and holding tank, is equipped with a plurality of trompils along same diametric (al) on the handle 201.

When the clamping arc-shaped section structure 2 needs to be moved, the positioning nail 4 is manually pulled to be separated from the clamp body 1 and the handle 201 until the positioning nail 4 is pulled, the handle 201 is pushed by the other hand, the positioning nail 4 pushes the handle 201 to slide under the action of the spring 5 until the next hole is reached, and under the action of the spring 5, the positioning nail 4 is bounced into the positioning holes of the handle 201 and the clamp body 1, so that the clamping arc-shaped section structure 2 is fixed.

In order to form a seal while clamping, as an improvement, the number of the clamping arc-shaped structures 2 is 4, and the 4 clamping arc-shaped structures 2 form a circular ring.

In order to stably cover the annular cover plate 3 on the clamping arc-shaped structure 2 and the arc-shaped protrusion 101, the clamping arc-shaped structure 2 and the arc-shaped protrusion 101 have the same thickness as each other as a modification.

As the corrugated pipe is a hose, in order to prevent damage and seal and fix tightly, as an improvement, a flexible arc-shaped strip 6 is fixed at one end of the clamping arc-shaped structure 2 close to the corrugated pipe.

The utility model discloses can be used in the in-process that the abrasive flow handled the metal collapsible tube inner wall, at this moment, open the through-hole that has the run through on the anchor clamps body 1, the bellows is metal collapsible tube.
