The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of circulation top-blown caliper as shown in Figure 1, mainly is made of pedestal, casing, master body, optical measuring head and mistake steel guide pin bushing.Casing vertically is packed in pedestal top, and pedestal is made of the left pedestal 4 of symmetry and right pedestal and a pedestal connecting plate 6, equal symmetrical location wheel 5 of installing on the left and right pedestal.Adopt bolt to be fixedly mounted with between main box bottom and left and right pedestal and the pedestal connecting plate.Box house is fixedly mounted with master body 11, installs many to optical signal launching tube 7 and optical signal receiving barrel 9 formations in the master surface.Optical measuring head all is connected and installed by clip 12 and master body.
The centre of casing connects installed the steel guide pin bushing, this caliper cross the steel guide pin bushing by level coaxial advance steel guide pin bushing 16 and tapping guide pin bushing 14 consists of, this advances between steel guide pin bushing and the tapping guide pin bushing to form the detection optical channel, this advances the steel guide pin bushing and wins in succession with described pedestal by guide pin bushing pole 15 separately respectively with tapping guide pin bushing bottom and be fixed, advancing the steel guide pin bushing is connected with guide pin bushing pole by guide pin bushing seat 20 respectively with the tapping guide pin bushing, guide pin bushing pole adjusting device 21 is installed, the height of realizing guide pin bushing pole is adjustable, when the stocking of rolling different-diameter, made steel guide pin bushing and stocking concentric by regulating to transmit.
The closed box of casing for being made of main box 10, casing shrouding 1 and end shield 3 is referring to accompanying drawing 2.Main box is that main box is integrated casting, present embodiment is circular, also can be square or other arbitrary shapes, be fixedly mounted with described casing shrouding in the positive outer ring of main box, be fixedly mounted with described end shield door at main box front inner ring, end shield door and casing shrouding are connected and fixed by snap close 2, form annular gap 13 between described main box and the end shield door, are provided with a ventilation shaft 8 at main box.Ventilation shaft is connected and installed a centrifugal blower 17 by pipeline 19, and this centrifugal blower connects a filter 18.Referring to Fig. 3.
The operation principle of this caliper is:
Clean compressed air through filter and centrifugal blower generation enters the box house with hermetically-sealed construction by pipeline; produce circulation top-blown air-flow at the place, annular gap; this air-flow has stoped on the one hand external oxidation iron sheet, dust etc. to enter in the main box and has protected the cleaning of camera lens; circulation top-blown air-flow is forming respectively two strands away from the air-flow group of main box into and out of steel guide pin bushing place on the other hand; so that be transferred to away from caliper by the heat that constantly distributes into and out of the steel guide pin bushing, see accompanying drawing 3.Secondly, circulation top-blown air-flow has changed the thermal convection current direction of measurement clearance place hot rolling material, this also be conventional water jacket can't be obtained.When the optical measuring head wiping of regularly carrying out caliper is safeguarded, but off-line (or online) can carry out after snap close takes off end shield by moving.
Although for the purpose of illustration disclosed embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that, in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, and therefore scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
