Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to a chuck with a limiting mechanism. Background Technology

[0002] A chuck is a type of clamping equipment that clamps the workpiece to be processed by controlling the movement of the jaw mechanism. A drive mechanism is set inside the chuck, which drives the opening and closing mechanism to move the jaw mechanism. The existing technology is to set a rack on one side of the jaw seat at the bottom of the chuck mechanism. The drive mechanism drives the rack through gears, which can control the movement of the jaw seat and thus realize the opening and closing of the jaws.

[0003] When using a chuck, the stroke of the jaw mechanism needs to be adjusted according to the specifications of the pipe fittings being clamped. If the stroke is too small, the clamping force will be insufficient, and if the stroke is too large, the clamped pipe fittings will be easily damaged. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a chuck with a limiting mechanism, which offers higher stroke adjustment accuracy and more convenient operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a chuck with a limiting mechanism, comprising a body, wherein the body is provided with a chuck mechanism, an opening and closing mechanism and a driving mechanism, wherein the driving mechanism can drive the chuck mechanism to open and close through the opening and closing mechanism, characterized in that: a limiting mechanism is provided on one side of the chuck mechanism, the limiting mechanism comprising a base and a limiting block, the limiting block being mounted on an adjusting rod on the base, the limiting block comprising a connecting part and a baffle, the base comprising an adjusting frame and a bottom plate, the adjusting rod passing through the connecting part and mounted on the adjusting frame, and being fixed by fixing bolts.

[0006] In the above technical solution, the upper part of the adjustment frame is provided with a bolt groove, and the fixing bolt passes through the bolt groove and is installed on the connecting part.

[0007] In the above technical solution, the main body is provided with two pairs of claw mechanisms, and each pair of claw mechanisms has a limiting mechanism on its side.

[0008] In the above technical solution, the adjusting rod is a bolt.

[0009] In the above technical solution, the end of the baffle is fitted with a bent section.

[0010] In the above technical solution, a buffer sleeve is provided at the end of the baffle.

[0011] Compared with the traditional technical means, the technical scheme of the utility model has the beneficial effect that the utility model sets the limiting mechanism on the side of the claw mechanism, the limiting mechanism can loosen the fixing bolt to greatly adjust the limiting clamping block, and also adjusts the relative position of the limiting clamping block and the claw through the rotation of the adjusting rod, so that the claw assembly can realize full stroke limiting, and the stroke of the claw mechanism is accurately controlled, and the operation is more convenient during adjustment, on the one hand, prevents insufficient clamping force caused by too small stroke, and on the other hand, prevents too large stroke, avoids damaging the clamped pipe fittings when clamping the thin-walled pipe.
