Abstract
The utility model discloses a hydraulic clamping cutter-relieving mechanism which comprises a support shaft, wherein the support shaft is mounted in a box body of a fixed clamping device and a box body of a floating clamping device in a penetrating mode, the top end of one end of the support shaft is fixedly provided with an oil cylinder connector, and the other end of the support shaft is fixedly provided with a transparent cover. A gland is arranged on the outer side of the transparent cover and connected with a piston on the support shaft, the gland and a second sliding sleeve are stacked and fixed on the floating clamping device, a first sliding sleeve is arranged below the second sliding sleeve and also fixed on the floating clamping device, and a dustproof jacket is arranged on the outer side of the first sliding sleeve. A stopping sleeve is further arranged on the fixed clamping device. The hydraulic clamping cutter-relieving mechanism can drive the floating clamping device to enable a pipe which is cut off to be separated from a saw blade after a saw cutting process is finished, and therefore the saw bade cannot scratch a cut face in the lifting process; in addition, before the saw blade is used for cutting next time, the saw blade automatically returns to an original position after returning to a cutting position so that the full-automatic process requirements of a steel tube frame saw machine are met; and the hydraulic clamping cutter-relieving mechanism has the advantages of being simple and compact in structure, high in cutter relieving speed and the like.
Description
Technical field
The utility model relates to and is applied to the mechanism that steel pipe saw and other sawings need to clamp cutter relieving, particularly a kind of hydraulic clamp relieving mechanism.
Background technology
Traditional clamping device does not clamp tool retracting device, lifts in the process at saw blade like this, and saw blade scratches the sawing section easily, affects product quality.The clamping device that perhaps has adopts the standard oil cylinder, makes the clamping device structure too huge and loose, and difficulty is installed.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of hydraulic clamp relieving mechanism, can be reliably and effectively realize clamping cutter relieving, and have simple and compact for structure, cutter relieving rapidly and can realize the advantage such as automation control.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of hydraulic clamp relieving mechanism, fixed clamping device 11 and floating clamping device 10 are linked together, comprise and run through the back shaft 2 that is installed in fixed clamping device 11 casings and floating clamping device 10 box houses, back shaft 2 one ends pass fixed clamping device 11 and the top is fixed with 2 cylinder connectors 1, back shaft 2 other ends are fixed with transparent cover 8, the outside of transparent cover 8 is glands 9, gland 9 is connected with piston 4 on the back shaft 2, gland 9 and 7 stacks of the second sliding sleeve are fixed on the floating clamping device 10, the below of the second sliding sleeve 7 is first sliding sleeves 6, the first sliding sleeve 6 also is fixed on the floating clamping device 10, the arranged outside of the first sliding sleeve 6 has dirt-proof boot 5, also be fixed with interstage sleeve 3 on the fixed clamping device 11, the inclined-plane of interstage sleeve 3 is relative with the inclined-plane of the first sliding sleeve 6.
This device can drive floating clamping device after sawing is finished makes the pipe of cut-out separate with saw blade, thereby make saw blade in lifting process, can not scratch section, and before next time sawing, saw blade automatically resets after getting back to cutting position, has satisfied the full-automatic technological requirement of steel tube gang saw machine.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done and to be described in detail.
With reference to accompanying drawing, a kind of hydraulic clamp relieving mechanism, fixed clamping device 11 and floating clamping device 10 are linked together, simultaneously can allow floating clamping device 10 stretch out and the retraction certain distance with respect to fixed clamping device 11, comprise and run through the back shaft 2 that is installed in fixed clamping device 11 casings and floating clamping device 10 box houses, back shaft 2 one ends pass fixed clamping device 11 and the top is fixed with 2 cylinder connectors 1, back shaft 2 other ends are fixed with transparent cover 8, the outside of transparent cover 8 is glands 9, gland 9 is connected with piston 4 on the back shaft 2, gland 9 and 7 stacks of the second sliding sleeve are fixed on the floating clamping device 10, the below of the second sliding sleeve 7 is first sliding sleeves 6, the first sliding sleeve 6 also is fixed on the floating clamping device 10, the arranged outside of the first sliding sleeve 6 has dirt-proof boot 5, also be fixed with interstage sleeve 3 on the fixed clamping device 11, the inclined-plane of interstage sleeve 3 is relative with the inclined-plane of the first sliding sleeve 6.
Operation principle of the present utility model is: this device is directly installed on fixed clamping device 11 casings and floating clamping device 11 box houses by back shaft 2 and transparent cover 8, gland 9, makes the structure of clamping device compacter, makes when clamping more reliable and more stable.During work, after fixed clamping device 11 and horizontal clamping device 10 are with tube grip, the hydraulic fluid port A oil-feed at cylinder connector 1 place, hydraulic fluid port B oil return, pushing piston 4 moves right, drive floating clamping devices 10 by gland 9 and move right, this moment, the inclined-plane of the first sliding sleeve 6 contacted with the inclined-plane of interstage sleeve 3, thereby with floating clamping device 10 and fix to clamp 11 devices and connect together.After sawing finishes, hydraulic fluid port B oil-feed, hydraulic fluid port A oil return promotes 4 pistons and is moved to the left, and drives floating clamping device 10 by gland 9 and is moved to the left, until piston 4 contacts with transparent cover 8.And sawing section and the saw blade of floating clamping mechanism side are isolated a segment distance at this moment, and saw blade makes saw blade separate with the section that fixes to clamp side by other a mechanism also mobile to the left segment distance, and then saw blade lifts.
