Abstract
The invention discloses a clamping cutter relieving device which comprises a supporting shaft which is arranged inside a fixed clamping device box body and a floating clamping device box body in a penetrating mode, wherein a cylinder joint is fixed on the top of one end of the supporting shaft; a transparent cover is fixed at the other end of the supporting shaft; the outer side of the transparent cover is provided with a gland; the gland is connected with a piston on the supporting shaft; the gland and a second sliding sleeve are fixedly superposed on a floating clamping device; a first sliding sleeve is arranged below the second sliding sleeve and is fixed on the floating clamping device; the outer side of the first sliding sleeve is provided with a dustproof cover; and a spacer sleeve is fixed on the fixed clamping device. According to the device, the floating clamping device can be driven after saw cutting is finished, so that the cut pipe is separated from the saw blade, and therefore, the saw blade is prevented from scratching the section in the lifting process; and moreover, the saw blade returns to a cutting position and is automatically returned before the next saw cutting, the full automatic process requirements of a steel pipe frame saw machine are met, and the clamping cutter relieving device has the advantages of simple and compact structure, rapid cutter relieving and the like.
Description
Technical field
The present invention relates to be applied to the mechanism that steel pipe saw and other sawings need to clamp cutter relieving, particularly a kind of tool retracting device that clamps.
Background technology
Traditional clamping device does not clamp tool retracting device, lifts in process like this at saw blade, and saw blade easily scratches sawing section, affects product quality.Or some clamping devices adopt standard oil cylinder, make clamping device structure too huge and loose, difficulty is installed.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of the present invention is to provide a kind of tool retracting device that clamps, can reliably and effectively realize clamping cutter relieving, there is simple and compact for structure, cutter relieving rapidly and can realize the advantages such as automation control.
In order to achieve the above object, technical scheme of the present invention is achieved in that
A kind of tool retracting device that clamps, fixed clamping device 11 and floating clamping device 10 are linked together, comprise and run through the back shaft 2 that is arranged on fixed clamping device 11 casings and floating clamping device 10 box houses, back shaft 2 one end pass fixed clamping device 11 and 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 the piston 4 on back shaft 2, gland 9 and the second sliding sleeve 7 stacks are fixed on floating clamping device 10, the below of the second sliding sleeve 7 is first sliding sleeves 6, the first sliding sleeve 6 is also fixed on floating clamping device 10, the arranged outside of the first sliding sleeve 6 has dirt-proof boot 5, on fixed clamping device 11, be also fixed with interstage sleeve 3, 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 that the pipe cutting off is separated with saw blade after sawing completes, thereby make saw blade in process, can not scratch section lifting, and before upper once sawing, saw blade automatically resets after getting back to cutting position, meet the full-automatic technological requirement of steel tube gang saw machine.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in detail.
With reference to accompanying drawing, a kind of tool retracting device that clamps, fixed clamping device 11 and floating clamping device 10 are linked together, can allow floating clamping device 10 stretch out and retraction certain distance with respect to fixed clamping device 11 simultaneously, comprise and run through the back shaft 2 that is arranged on fixed clamping device 11 casings and floating clamping device 10 box houses, back shaft 2 one end pass fixed clamping device 11 and 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 the piston 4 on back shaft 2, gland 9 and the second sliding sleeve 7 stacks are fixed on floating clamping device 10, the below of the second sliding sleeve 7 is first sliding sleeves 6, the first sliding sleeve 6 is also fixed on floating clamping device 10, the arranged outside of the first sliding sleeve 6 has dirt-proof boot 5, on fixed clamping device 11, be also fixed with interstage sleeve 3, the inclined-plane of interstage sleeve 3 is relative with the inclined-plane of the first sliding sleeve 6.
Operation principle of the present invention is: this device is directly installed on fixed clamping device 11 casings and floating clamping device 10 box houses by back shaft 2 and transparent cover 8, gland 9, makes the structure of clamping device compacter, more reliable and more stable while making to clamp.When work, when fixed clamping device 11 and horizontal clamping device 10 are by after tube grip, the hydraulic fluid port A oil-feed at cylinder connector 1 place, hydraulic fluid port B oil return, promoting piston 4 moves right, drive floating clamping device 10 to move right by gland 9, now the inclined-plane of the first sliding sleeve 6 contacts with the inclined-plane of interstage sleeve 3, thus by floating clamping device 10 with 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 to be moved to the left, until piston 4 contacts with transparent cover 8 by gland 9.And now the sawing section of floating clamping mechanism side and saw blade are isolated a segment distance, saw blade, by other a mechanism also mobile to the left segment distance, makes saw blade separate with the section that fixes to clamp side, and then saw blade lifts.
