Description
Technical field
The present invention relates to a kind of single face corrosion or clean the single face corrosion of anchor clamps, particularly discoid optical sample or the anchor clamps of cleaning usefulness.
Technical background
Many discoid optical samples need corrode or clean an end face and protect another end face; for example; microchannel plate, fibre optic faceplate; often because of the concrete needs of using; the core material or the cladding of an end face of selective corrosion; and to protect other polished end face well, people often coat erosion-resisting paraffin or protective paint in this protective surface, treat to wash paraffin or protective paint off with aviation gasoline again after a burn into cleans.Consider corrosive medium acid, alkali or organic solvent and being used alternatingly between them often; for accelerated corrosion speed often adopts ultrasonic, magnetic agitation and is accompanied by ancillary methods such as heating; like this; often cause a part or whole part of paraffin or protective paint to come off; cause protected initial quality to can not get ensureing at all; other similar measure also difficulty produces a desired effect; and the those skilled in the art of the industry are difficult to walk out these mistaken ideas; always on the selection protective material, work hard, but result of the test is always unsatisfactory.
Summary of the invention
The present invention is exactly at above-mentioned defective and specialized designs one sleeve clamp, with one or two sample wait corrode or the one side of cleaning and the sealing of protected another side isolated, be implemented under the prerequisite of a fine protection of end face, corrode or clean another end face.Making the material of anchor clamps can determine according to concrete corrosive medium, certain pliability is preferably arranged so that by turning or pushing in the contact position impermeable solution.As for acid, alkali or organic media, select polytetrafluoroethylene (PTFE).These anchor clamps are by stem stem, pressure ring and bung flange are formed, stem stem is to be used for carrying sample and to guarantee a not contact corrosion of end face or cleansing medium and effective district of another end face fully is exposed among corrosion or the cleansing medium by the cooperation of pressure ring and bung flange, be used to carry sample at the inboard design in stem stem upper end one step, its external diameter equates with the external diameter of sample and the straight tube of pressure ring, and internal diameter equates with the effective diameter of sample and the internal diameter of pressure ring, step increases by 2～5mm on the basis of the degree of depth at thickness of sample of upper surface, simultaneously, the internal thread facing-up of the external screw thread of end periphery and bung flange on the stem stem, with guarantee bung flange pass through the external screw thread of the raised ring of pressure ring and stem stem fixing after, impermeable solution is located in each slit.Uniform four the vertical penetrating grooves of end periphery on the stem stem, the width of groove is at 3～6mm, and the degree of depth is to arrive 1/3～1/2 of step width from the side, so that load and unload sample with tweezers.Consider and lay down the sample inconvenience sometimes, establish a through hole at the stem stem center, the cylinder of itself and lower end is coaxial and penetrating, the diameter of the penetrating part in center, upper end arrives between the step internal diameter at 5mm, lower end barrel bore design is arrived between the step internal diameter at 10mm, this structure cooperates with pressure ring and bung flange, can only corrode an end face of a sample at every turn.In order to protect another surface of sample, make its effective district not contact anchor clamps, the shoulder height of design should be at 2～4mm.Diameter as center, stem stem upper end is identical with the barrel bore of lower end, and equals the internal diameter of step, and then a clamping can corrode each end face of two samples.The upper and lower end of above-mentioned stem stem is an one, and according to the size and the concrete condition of corrosion container, can make the upper end highly is 13～20mm, and the lower end height is 10～50mm.
Pressure ring is a cylindrical shape, and in its side one raised ring is arranged, and raised ring is securely fixed in the anchor clamps sample by bung flange with being threaded of stem stem.As indicated above, its inside and outside footpath equates with the interior external diameter of step respectively, considers the solution sealing, and the step external diameter of its external diameter and stem stem should closely cooperate.The raised ring of pressure ring and pressure ring are one, and insert behind stem stem from the stem stem upper surface its lower end is 2～6mm, and the raised ring height is 2～4mm, and the raised ring upper end is 10～20mm to the distance on the pressure ring.
Bung flange is that sample is fixed on the step of stem stem by pressure ring and stem stem, guarantee another side obtain fine protection and wait to corrode or cleaning surface can be exposed to well the corrosion or cleansing medium among.Design its shape and be similar to the lid shape thing that penetrating part is arranged at the top, the total height (being the degree of depth) of the female thread portion of its medial surface and escape part equals stem stem load onto sample after, pressure ring is squeezed on the sample, its raised ring upper end is to the distance of stem stem upper end lower limb, bung flange thickness everywhere is 2～4mm, the diameter of the penetrating part in bung flange upper end is greater than the external diameter 0.5～1.5mm of pressure ring, than the little 2～8mm of diameter of pressure ring raised ring.Skid in order to prevent to turn, the bung flange lateral surface is provided with equally distributed groove or projection.
Above-mentioned three parts cargo handling processes are as follows: at first stem stem is placed on the platform, periphery has an externally threaded end up, sample is contained on the step of stem stem with tweezers, the most advanced and sophisticated orientation of tweezers is relative with groove, pushes the sample periphery gently with the lower end of pressure ring, and bung flange is tightened by pressure ring and with the upper end screw thread of stem stem, the pressure ring inner core is injected deionized water, as impermeable for a long time, then can corrode or cleaning, otherwise ressemble.The dismounting order is not done too much description with above-mentioned opposite at this.
Above-mentioned loading and unloading are just corroded at the single face of a sample, can handle corresponding each end face of two samples simultaneously as clamping, then need pad to go up glassine paper, cigarette paper or the lens paper of the softness of same diameter in the middle of two samples, adopt the diameter stem stem identical with the barrel bore of lower end at center, upper end, the single face corrosion of handling method thereafter such as a slice sample is identical.
The technical barrier that the present invention has caused protected other end difficult quality to ensure when well having solved corrosion or having cleaned the single face sample, handling ease, easy to operate, reach the expection practical function.
