The outer surfaces of the sliding blocks are parallel to the inner surfaces of the check blocks, and the inner surfaces of the sliding blocks are cylindrical curved surfaces and provided with slip sheets. According to the hydraulic pipe clamp, the problem that a pipe is inconvenient to clamp in the machining process in the prior art is solved, and the aim of conveniently and fast fixing the pipe to be machined is achieved.
Description
Technical field
The present invention relates to clamping device field, specifically relate to a kind of fluid pressure type tubing fixture.
Background technology
Clamping device is equipment conventional in various mechanical processing process, and it, for fixing material to be processed or parts, is guaranteed that it can not be moved and skew in process, avoid the bias effect of article to be processed to operate.For columniform tubing, in production and processing, very easily roll in cutting process, more need to be fixed, then carry out follow-up work.Existing tubing fixture adopts chain or pipe wrench to be fixed usually, but when needing stretch to tubing or act on larger power, easy appearance takes off the phenomenons such as pipe, displacement, firm fixing tubing can not be stablized, and tubing can be beated in rotary course, affect the cutting of tubing, polishing and other processing effects.In addition, pipe clamping device of the prior art mostly is baroque large pipe clamping device, or simple Purely mechanical clamping device; Large-scale clamping device huge structure, complicated operation, suitable application area is limited, and simple Purely mechanical clamping device exists above-mentioned to the unstable problem of pipe clamping.In a word for the difficulties that tubing fixing is in tubular object extruding process always.
Summary of the invention
The object of the present invention is to provide a kind of fluid pressure type tubing fixture, solve the problem of inconvenience clamping in tubular object extruding process in prior art, realize the object of fixing tubing to be processed easily and efficiently.
The present invention is achieved through the following technical solutions:
A kind of fluid pressure type tubing fixture, comprise hydraulic pump, urceolus, inner core, annular space between described urceolus and inner core forms hydraulic cylinder, be provided with the piston of annular in described hydraulic cylinder, the end winding support of described urceolus has the block of taper, described piston is hinged with two symmetrical connecting rods, the other end of described connecting rod is all hinged with slide block, described outside face thereof is parallel with described block inner surface, and described slide block inner surface is Cylinder Surface, and described slide block inner surface is provided with slips sheet.Complicated or clamp not strongly solid problem for existing pipe clamping apparatus structure, the present invention proposes the simple hydraulic clamping device of a kind of structure, clamping is stable to provide power to guarantee by hydraulic pump.Hydraulic pump of the present invention is communicated with the annular space between described urceolus, inner core, and namely this annular space constitutes hydraulic cylinder.In use procedure, first by manpower or suspender by tubing to be processed from a segment distance in the end feeder of described urceolus, now primer fluid press pump pressurization, pressure increase in described hydraulic cylinder, promote piston, connecting rod, and slide block moves forward, described slide block movement is to block place, because outside face thereof and the inner surface of described block are parallel inclination curved surface, and described connecting rod two ends are all chain connections, so described slide block internally can slide along the inner surface of described block, and also drive described connecting rod to slope inwardly, keep the connection of slide block and piston, make the slips sheet of slide block inner surface embrace tubing to be processed simultaneously, realize the object utilizing hydraulic clamping tubing.After tubular object extruding terminates, only need by hydraulic pump to hydraulic cylinder pressure relief, piston and connecting rod retreat, and slide block resets, and slips sheet can unclamp tubing, completes clamping process.
Further, the tooth of described slips sheet tilts towards described connecting rod direction.Namely the tooth of described slips sheet is inside pawl, thus guarantees firmly to catch tubing to be processed, avoids its displacement or rotates.
Further, the surfaces externally and internally of described piston is provided with O ring recess.All assemble O circle in the O ring recess on inside and outside surface, be respectively used to packed-piston and inner core, gap between piston and urceolus, prevent the hydraulic oil in hydraulic cylinder from overflowing and cause hydraulic means to lose efficacy.
To sum up, the present invention has following beneficial effect:
The promotion to slide block is realized by hydraulic means; By block and the slide block of given shape, realize the control to slide block trend; The clamping treating processing tubing is realized by the slips of slide block inner surface.
