In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Combine the following Figures 1 to 3 , describes an anti-deformation chuck for thin pipes according to an embodiment of the utility model, comprising a chuck body, the chuck body being provided with a through slot for the pipe to pass through; the chuck body being provided with a clamping mechanism, the clamping mechanism comprising a driving part and two clamping claws relatively distributed on both sides of the through slot, the driving part being respectively connected to the two clamping claws in a transmission manner to drive the two clamping claws to synchronously move toward and away from each other in a straight line direction, characterized in that:

[0022] The clamping mechanism also includes a limit assembly, which includes a connecting seat, a limit seat and an adjusting screw. The connecting seat is fixedly mounted on the chuck body, the limit seat is connected to one of the jaws of the mechanism, the limit seat is provided with a limit sleeve hole, the adjusting screw is threadedly connected to the limit seat after passing through the limit sleeve hole, and a spacing distance is provided between the head of the adjusting screw and the connecting seat.

[0023] In the utility model, when the driving unit drives the two clamping claws to approach synchronously, it also drives the limit seat to move relative to the adjusting screw until the limit seat abuts against the head of the adjusting screw to limit the limit seat from moving further, thereby causing the driving unit to stop the two clamping claws from approaching each other, thereby preventing the clamping claws from squeezing the pipe and causing the pipe to deform. By rotating the adjusting screw to change the distance between the head of the adjusting screw and the connecting seat, the stroke of the clamping claw is adjustable and variable to adapt to pipes of different sizes, so that the chuck has good applicability.

[0024] Optionally, the connection seat includes a connection plate and two vertical plates, two adjusting screws are provided, the connection plate is connected to the chuck body, the vertical plate is vertically arranged on the connection plate, and the two vertical plates are located on both sides of the clamping jaw, and the two adjusting screws are correspondingly threadedly connected to the vertical plates. In this way, the two sides of the clamping jaw are limited, so that the force on the clamping jaw is balanced, and the stability of the clamping jaw is improved.

[0025] Specifically, optionally, the driving part is two cylinders, and the two cylinders are controlled by the system to extend and retract simultaneously. The chuck body is provided with a limit slide, the driving part is arranged in the limit slide, and the telescopic end of the driving part is provided with a limit block, the limit block is slidably matched with the limit slide, and the claw is connected to the telescopic rod of the driving part. The telescopic direction of the driving part is limited by the sliding cooperation between the limit block and the limit slide, so that the claw moves along the preset direction.

[0026] Specifically, the clamping claw comprises a clamping claw body and a round tube, and two spaced connection parts are provided on one side of the clamping claw body close to the center of the through slot, and the round tube is provided between the two connection parts, and the two ends of the round tube are rotatably connected to the corresponding connection parts respectively. The rotatable round tube is in contact with the pipe material, so that the friction between the pipe material and the clamping claw is reduced, and the pipe material is protected. At the same time, the clamping claw only provides radial force, not axial force, and the processing accuracy of the pipe cutting machine is increased.

[0027] Specifically, the number of the claw bodies and the round tubes is two, the two claw bodies are overlapped, and the two round tubes are correspondingly mounted on the claw bodies, so that double-point contact fixation in one direction is achieved, thereby improving the stability of the chuck in clamping the pipe.

[0028] Specifically, the clamping mechanism is provided with two, four clamping jaws distributed in a circular array with the center of the through slot as the center, so as to achieve clamping of the pipe in four directions, so as to improve the stability of the chuck clamping the pipe.

[0029] The second aspect of the utility model discloses a pipe processing equipment, including the above-mentioned anti-thin pipe deformation chuck. In the material processing equipment of the utility model, when the pipe needs to be clamped, the pipe passes through the through slot, and the driving unit drives the two claws to approach synchronously, and at the same time drives the limit seat to move relative to the adjusting screw until the limit seat abuts against the head of the adjusting screw to limit the limit seat from moving further. At this time, the claws also abut against the pipe to clamp the pipe. Due to the limiting effect of the adjusting screw, the driving unit stops the two claws from approaching each other, so as to avoid the situation where the claws squeeze the pipe and cause the pipe to deform. Among them, the distance between the head of the adjusting screw and the connecting seat is changed by rotating the adjusting screw, so that the stroke of the claws can be adjusted and varied to adapt to pipes of different sizes, so that the chuck has good applicability.

[0030] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
