Abstract
The utility model discloses a kind of device for quick-detachment Small Cylindrical face, it is characterized in that: comprise that two with upper chuck (1), described chuck (1) inner side is clamping face, and after all chucks (1) combination, the clamping face of inner side can clamp the face of cylinder to be removed; Between described chuck (1), clamp by pinching screw (2); On at least two chucks (1), be provided with handle (3).The utility model is simple in structure, easy to use, flexible, quick release import screw-in cartridge valve, also can be used to dismantle the relief surface often running in routine work and be cylindrical, clamping face is shorter, need the part that very high-torque could be dismantled.
Description
Technical field
The utility model relates to a kind of extracting tool, relates in particular to a kind of device for quick-detachment Small Cylindrical face.
Background technology
Its relief surface often running in import screw-in cartridge valve and routine work is that column type, clamping face are shorter, the needs parts that very high-torque could be dismantled, and owing to there is no suitable provision for disengagement, is difficult to dismantle.Relatively more typical in import screw-in cartridge valve, through development for many years, there is the series of advantages such as volume is little, compact conformation, applying flexible, easy to use, leakage rate is low, stationarity is good, reliability is high, therefore on high-altitude operation vehicle, obtained being widely used, it is leading domestic working arm future development trend.Promoting the use of of import screw-in cartridge valve allows the indices of high-altitude operation vehicle produce qualitative leap, working arm size decreases, operating radius increased, price has reduced, arm shake and arm seriously sink problem also solve.But because import screw-in cartridge valve is not easy dismounting, and design is more accurate, often there will be jam phenomenon in use procedure, and resistance tocrocking is poor.Thoroughly remove if be stuck in the foreign matters of valve core inside, screw-in cartridge valve the lighter performance reduces brings whole vehicle functions to decline, and severe one disabler exists potential safety hazard.
Due to import screw-in cartridge valve and other relief surface parts that are cylindrical structure, appearance and size is little, clamping face generally only has 5mm left and right, while adding the assembling of upper inlet screw-in cartridge valve, can be coated with binding thread glue, finally adopt special equipment to tighten acquisition, therefore use the such instrument of pipe vice to be difficult to carry out clamping dismounting.For similarly not easily detachable parts of import screw-in cartridge valve and other, those skilled in the art still feel simply helpless at present, for the import screw-in cartridge valve that cannot clean reparation after jam or pollution, general employing scrapped processing, causes very large economic loss for this reason.
Summary of the invention
Goal of the invention: the utility model object is a difficult problem that cannot detachable maintaining for existing import screw-in cartridge valve and similar parts, and a kind of device that is specifically designed to quick-detachment Small Cylindrical face is provided, and has really solved the problem of screw-in cartridge valve detachable maintaining.
Technical scheme: the device for quick-detachment Small Cylindrical face described in the utility model, comprise that two with upper chuck, described chuck inner side is clamping face, after all chuck combinations, the clamping face of inner side can clamp the face of cylinder to be removed; Between described chuck, clamp by pinching screw; On at least two chucks, be provided with handle.
Preferably, described chuck is three, is divided into three obtains by circular discs integral cutting one.After well cutting, three chucks are beaten to steel seal label note three position relationship.Finally three chuck surfaces are carried out to cure process, ensure this device service life.
Preferably, in the cutting between described chuck, seam is 2～3mm.
Preferably, on described chuck, be respectively arranged with handle, three handles are uniformly distributed and are fixed on circular discs lateral surface.Three handles uniform stresseds simultaneously when dismounting, can avoid the lever operated generation radial force of tooling order of pipe vice one class like this, effectively avoid the damage of radial force to split part.
In order to ensure chuck quality of fit, preferably described circular discs is carbon tool steel or alloy tool steel board matter.
In order to ensure that clamping chuck face can the reliable grip face of cylinder, on described clamping face, be provided with anti-slop serrations structure.
The structure of anti-slop serrations is processed as required, and preferably, described anti-slop serrations structure is stepped tooth, rectangular teeth or rake tooth structure.
Preferably, described pinching screw enters from the lateral surface of a slice chuck, gos deep into adjacent chuck inside, and two adjacent chucks are clamped.
Beneficial effect: the utility model is simple in structure, easy to use, flexible, quick release import screw-in cartridge valve, also can be used to dismantle the relief surface often running in routine work and be cylindrical, clamping face is shorter, need the part that very high-torque could be dismantled.

Detailed description of the invention
Below by accompanying drawing, technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
embodiment 1:a kind of device for quick-detachment Small Cylindrical face, as shown in Figure 1, comprise three chucks 1, three chucks circular discs integral cutting one is as shown in Figure 2 divided into three and obtains, described circular discs is carbon tool steel or alloy tool steel board matter, in cutting between described chuck 1, stitching 5 is 2～3mm, after well cutting, three chucks is beaten to steel seal label note three position relationship.Described chuck 1 inner side is clamping face, and φ D is this device clamping diameter, and after three chucks 1 combinations, the clamping face of inner side can clamp the face of cylinder to be removed; On described clamping face, be provided with anti-slop serrations structure 4, described anti-slop serrations structure 4 can be selected as required, as stepped tooth, rectangular teeth or rake tooth structure; Between described chuck 1, clamp by pinching screw 2, described pinching screw 2 enters from the lateral surface of a slice chuck, gos deep into adjacent chuck inside, and two adjacent chucks are clamped; On described chuck 1, being respectively arranged with 3, three handles 3 of handle is uniformly distributed and is fixed on circular discs lateral surface.
Operation principle: as shown in Figure 4, six cylinders are fixed, the split spool face of cylinder is put in the middle of chuck 1, regulate pinching screw 2 until chuck 1 clamps the spool face of cylinder, part is evenly pulled three operating grips 3 after clamping, until spool dismounting is come.
Too tightly cause split part cylindrical to produce distortion for preventing that chuck 1 from holding, pinching screw 2 screw-down torques can not be too large, otherwise can cause split part to be scrapped, rule: clamping force regulates and minimizes as far as possible, as long as it is rear without non-slip in distortion, unloading process to ensure that split part clamps.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
