Abstract
The utility model discloses a pipe clamping device comprising an internal chuck, a spring chuck, a moving sleeve, a thrust bearing, a ratchet mechanism and a sliding rack. The internal chuck is disposed inside the spring chuck; the moving sleeve is arranged outside the spring chuck; the moving sleeve is driven to move by the thrust bearing; the thrust bearing is driven by the ratchet mechanism; an arc gear matching with a gear of the sliding rack is disposed on the ratchet mechanism; the sliding rack is pneumatically driven to rotate. The pipe clamping device is adaptable to clamping of pipes different in shape and diameter; the whole pipe clamping mechanism is integrated with pneumatic drive, and operation is simple and safe; the pipe clamping device is also applicable to reshaping of round tubes of certain deformation, and high roundness of the round tubes ensures cutting precision.
Description
Technical field
The utility model relates to a kind of clamping device, relates in particular to a kind of pipe clamping device.
Background technology
At present tubing produce and follow-up processing, cutting process in need tubing to be fixed, then carry out follow-up work.Existing tubing fixture adopts chain or pipe wrench to be fixed conventionally, but when needs stretch to tubing or when larger active force, easily there is the phenomenons such as de-pipe, displacement, can not stablize firm fixing tubing, and tubing can beat in rotary course, affect the cutting effect of tubing.In the time of incising pipes, how to fix rectangular tube and be always a difficult point, in prior art or complex structure, or be difficult to firmly fixing.
Summary of the invention
The utility model aims to provide a kind of pipe clamping device, can adapt to different shapes and the tubing of diameter, fixation, simple in structure.
For achieving the above object, the technical solution of the utility model is: a kind of pipe clamping device, comprise built-in chuck, collet, moving sleeve, thrust bearing, ratchet mechanism and sliding rack, described built-in chuck is placed in collet, collet outer race has moving sleeve, described moving sleeve is driven mobile by thrust bearing, described thrust bearing is driven by ratchet mechanism, on described ratchet mechanism, be provided with the wildhaber-novikov gear coordinating with the gear of sliding rack, described sliding rack rotates by gas drive is moving.
Further, described ratchet mechanism comprises the first ratchet mechanism and the second ratchet mechanism, on described the second ratchet mechanism, be provided with the wildhaber-novikov gear coordinating with the gear of sliding rack, the first ratchet mechanism is provided with projection, is provided with the groove coordinating with projection in holder two.
Further, described moving sleeve outer race is equipped with bearing, between described thrust bearing and bearing, is provided with spring, and described spring is fixed on connecting plate.
Further, described collet is made up of spring steel, and collet end is provided with four grooves, and described groove is divided into pintongs end.
Further, described sliding rack two ends are provided with sealing shroud, and described sliding rack seals by seal plug in the through hole of holder two.
Further, described built-in chuck is square or circular.
The beneficial effects of the utility model are: pipe clamping device of the present utility model, can be suitable for the tubing clamping of difformity (square tube, rectangle, ellipse, circle) and diameter.Clamping is to clamp product by collet deformation, and collet pintongs is the while stressed (stressed in the same size), and deformation quantity is consistent, can ensure the pivot degree of product.Whole mechanism and pneumatic realize integrated, simple to operate, safety, pipe that can also the certain deformation quantity of shaping, makes the higher cutting accuracy that ensures of its out of roundness.The appearance and size that total is compared other similar means is much smaller, and is convenient to install.
