Description
Technical field
The present invention relates to a kind of aid of analytical instrument, belong to metallurgical analysis detection technique field, especially a kind of sample analysis anchor clamps that are used for direct-reading spectrometer.
Background technology
Direct-reading spectrometer is the analytical instrument with advanced level; Be widely used in industries such as mechanical, coloured, iron and steel, but along with the increase of enterprise production, the quickening of rhythm of production; The kind of analytic sample is also more and more, and the frequency of utilization of spectrometer also constantly rises thereupon.Usually; The analytic sample shape is varied; What direct reading spectrometry excited platform excites the aperture big and immobilize; Therefore can not satisfy the multifarious needs of sample, particularly small bore sample, such as the analysis of the small-size shaft class of diameter 6mm-10mm, round steel, wire rod, welding rod, rigid line equal diameter than small sample.If after drilling through steel cuttings, adopt its chemical constitution of wet-way analysis, analysis speed is slower; If increased human and material resources and time cost, inapplicable gross sample analysis when using machine tool cold-heading or flattening especially.Generally be not more than the test button of 14mm for diameter, need be by means of the sample analysis anchor clamps.
Through retrieval; Xinxing Cast Pipes Co., Ltd has applied for that in 2011 a patent No. is 201120291196.6 utility model patent, and this patent discloses a kind of analytic sample setting tool that is used for direct-reading spectrometer, and this setting tool comprises base plate and sleeve pipe; Through hole on sleeve pipe and the base plate is slidingly matched; Internal surface of sleeve pipe is provided with the cushion rubber of fixed sample, and this device is to the sample of different size, and the cushion rubber that needs to be equipped with different sizes fixes sample; Can not adjusting of device itself, so its scope of application limits to some extent.
In addition; Application number is that 98212684.0 patent discloses a kind of photo-electric direct reading spectrometer and analyzes the small bore test button and use anchor clamps; These anchor clamps comprise tool cover, chuck body, jaw and involutory internal thread circle, and three the oblique circular holes that evenly distribute around the chuck body are installed mobile jaw in each oblique circular hole; And the slope of thread in the jaw outside is consistent with the gradient of oblique circular hole; Involutory internal thread circle is stuck in the draw-in groove of chuck body, and internally the screw thread in the fillet of screw is identical with the screw thread on the jaw, and the anchor clamps cover is sleeved on the chuck body and the involutory internal thread circle of burst is stuck.Chuck body in these anchor clamps is provided with oblique circular hole; The non-central hole of this type is not easy processing, and jaw is provided with in the oblique circular hole in addition, and can only be provided with three; These three jaws are contacts when contacting with metal sample; Fix sample through extruding, therefore be easy to occur becoming flexible, thus the impact analysis process.
Summary of the invention
The technical matters that the present invention will solve provides kind of a kind of sample analysis anchor clamps that are used for direct-reading spectrometer; These anchor clamps not only can freely be adjusted folder mouthful size, the scope of application is wide, and easy to operate, and precision is high; The result is accurate, can satisfy the requirement of production and scientific research.
For solving the problems of the technologies described above; The technical scheme that the present invention taked is: a kind of sample analysis anchor clamps that are used for direct-reading spectrometer; It is characterized in that comprising the disk body of columniform shell, enclosure and pass shell and the disk body sidewall and the plural claw that can radially slide along shell, the center of said shell and disk body is provided with through hole, and claw is uniformly distributed on the sidewall of shell; The top of claw is provided with and drives the silk dish that claw radially slides; Said silk dish is positioned at the top of shell, and with the shell clamping, the silk dish is rotatably assorted with disk body.
Said structure is done further restriction, and the side of said shell and disk body is evenly distributed with three I shape slotted eyes on same surface level, and the profile of said claw cooperates with the I shape slotted eye, and the claw length direction points to the center of shell.The present invention lays three I shape slotted eyes on shell and disk body circumferencial direction, through the slotted eye guiding, claw is slided in the I shape slotted eye, can realize the sample of clamping different size, increases usable range.
Said structure is done further restriction, and the joint end of said claw is connected with fixed claw, and the front end surface of said fixed claw is an arc, and front end surface inside is inlaid with caulking gum.The present invention fixes through key screw fixed claw, claw and caulking gum, and the three can be in the same way, with the speed motion, because the fixed claw surface is an arc; The arc radius of the caulking gum that uses simultaneously equates; After sample was stepped up, caulking gum can be close to by sample surfaces, friction force between can increasing; Prevent the sample landing, improve accuracy and the precision measured.
Said structure is done further restriction, and the upper surface of said silk dish is provided with spiral flat thread, and the lower surface of each claw is provided with the screw thread with the flat thread engagement, and the upper surface of silk dish contacts with the claw lower surface.The spirality flat thread of silk panel surface of the present invention and the screw-threaded engagement of card bundle; The silk dish drives claw through rotation and passes in and out along the I shape slotted eye; This spiral flat thread can make claw at the uniform velocity mobile, be converted into straight line rotating in a circumferential direction and move, and displacement is controlled easily; Method is easy, is convenient to safeguard and promote.
Said structure is done further restriction, and said silk dish below is provided with the disk body that is slidingly matched with it, is provided with draw-in groove in the said disk body, and the draw-in groove internal fixation has the jump ring that prevents that the silk dish from coming off.
Said structure is done further restriction, and the side of said silk dish and disk body is provided with the aperture that is used to insert the reinforcement bar.In the use, can utilize the reinforcement bar to rotate the silk dish among the present invention, fixedly disk body is easy to adjust quick.
Adopt the beneficial effect that technique scheme produced to be: the present invention is through reinforcement bar rotation disk body and silk dish, and disk body drives claw and moves along the I shape slotted eye, realizes sticking into sample; This device is applicable to the sample analysis in various cross sections; The less sample of area of section particularly, the I of the diameter of sample reaches 6mm, and easy to operate; Can sample firmly be placed, prevent that sample from can't fix the inconvenience that brings to analysis operation because of size is little; The present invention more is applicable to the spectral component analysis of the low alloy steel sample that small-size shaft class, round steel, wire rod, welding rod, rigid line equal diameter are less, and method is easy, is convenient to promote and safeguard, precision is high, and the result is accurate, can satisfy and produce and the requirement of scientific research.Of the present invention with low cost, not only can analyze the sample of various miniature dimensions, and expand the usable range of instrument.
