The dial indicator is composed of a dial body, a fixed rod, a movable rod and a measuring rod which is arranged at the lower end of the movable rod, and the lower end of the measuring rod is connected with a proofreading rod through a connecting rod; the sleeve is sleeved at the periphery of the measuring rod, the upper end of the sleeve is connected with the fixed rod, the proofreading block is provided with a tapered hole for inserting the proofreading rod in the length direction, and the inner wall of the tapered hole is in contact with the outer wall of the proofreading rod; and a fixed block capable of moving up and down along the sleeve is sleeved at the periphery of the lower part of the sleeve. The gauge disclosed by the utility model can be used to measure the angle of a tapered hole of a deep hole quickly and accurately, the human factors can be reduced, and the consistency of products can be ensured.
Description
Technical field
The utility model relates to a kind of survey instrument, especially relates to a kind of cubing for measuring the bellmouth angle.
Background technology
Adopt the two-way heating power expansion valve of taper valve port throttling, in valve port processing and checkout procedure, because its straight hole adds the taper pore structure, at present the angle of bellmouth do not had infallible detection means, mostly adopt range estimation, consequently degree of accuracy is low, human factor is large, and homogeneity of product is poor.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, and a kind of simple in structure, the cubing that can fast, accurately measure the bellmouth angle is provided.
To achieve these goals, the utility model is by the following technical solutions: a kind of cubing of measuring the bellmouth angle, comprise dial gauge, sleeve and proof-reading block, dial gauge is made of table body, fixed bar and the sounding rod of being located at the fixed bar lower end, and the bottom of sounding rod is connected with a correcting rod by connecting link; Jacket casing is located at the periphery of sounding rod, and the upper end of sleeve is connected with fixed bar, and proof-reading block is provided with the taper hole that inserts for sleeve along its length, and the bottom surface excircle of the outer wall of correcting rod and sleeve all contacts with the inwall of taper hole; The bottom outer race of sleeve is provided with a fixed block that can move up and down along sleeve.
As preferably, described lower cartridge is provided with one and falls " U " shape groove, and " U " shape groove that should fall comprises minor face groove, long limit groove and base, and the lower end of long limit groove is communicated with the end of sleeve; Described fixed block inwall is provided with and falls the projection that " U " shape groove matches.
As preferably, the sidewall on the top of described sleeve is provided with threaded hole, is provided with a clamping screw in the threaded hole.
The utlity model has following advantage: the utility model can fast, accurately be measured deep hole bellmouth angle, reduces human factor, guarantees the consistance of product.

Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
Shown in Fig. 1-4, a kind of cubing of measuring the bellmouth angle, comprise dial gauge, sleeve 3 and proof-reading block 5, dial gauge is made of table body 7, fixed bar 8 and the sounding rod 4 of being located at fixed bar 8 lower ends, and the bottom of sounding rod 4 is connected with a correcting rod 92 by connecting link 91; Sleeve 3 is sheathed on the periphery of sounding rod 4, and the upper end of sleeve 3 is connected with fixed bar 8, and proof-reading block 5 is provided with the taper hole 51 that inserts for sleeve 3 along its length, and the bottom surface excircle of the outer wall of correcting rod 92 and sleeve 3 all contacts with the inwall of taper hole 51; The bottom outer race of sleeve 3 is provided with a fixed block 1 that can move up and down along sleeve 3.Sleeve 3 bottoms are provided with one and fall " U " shape groove, and " U " shape groove that should fall comprises minor face groove 21 and long limit groove 22, and the lower end of long limit groove 22 is communicated with the end of sleeve 3; Described fixed block 1 inwall is provided with and falls the projection that " U " shape groove matches.The sidewall on the top of sleeve 3 is provided with threaded hole, is provided with a clamping screw 2 in the threaded hole.
The maximum outside diameter of correcting rod 92 must be less than the external diameter of sleeve 3, and must be greater than the minimum diameter of measured workpiece 6 bellmouths, and the external diameter of sleeve 3 must be less than the maximum gauge of measured workpiece 6 bellmouths, and must be greater than the minimum diameter of measured workpiece 6 bellmouths.The external diameter of locating piece 1 must be greater than the maximum end diameter of bellmouth 51.This method is to utilize the circle of the different-diameter of two circles on same straight line, and centre distance is different, and its public outer tangent line is different from the angle of center line.
During use, first sounding rod is connected with dial gauge, sleeve is placed on the fixed bar of dial gauge again, lock with clamping screw.Locating piece is packed into from the inverted U-shaped flute length limit groove on the sleeve, by the U-lag base, rotate to again the minor face groove, fixed block can be moved freely in vertical direction, and other directions are tied, as shown in Figure 3, Figure 4.Sounding rod is inserted in the proof-reading block again, make sleeve bottom surface cylindrical and standard zeroing proof-reading block conical inboard wall close contact, locating piece is subjected to gravity automatically and standard zeroing proof-reading block upper surface is fitted, and guarantees verticality.This moment the sounding rod end correcting rod can be because self elastic force of dial gauge and standard return to zero the tight line of conical inboard wall of proof-reading block contact.Turn the dial gauge dial plate, make pointer to zero.Then, sleeve is inserted the measured workpiece deep hole, as shown in Figure 2, make sleeve bottom surface cylindrical and measured workpiece circular cone inwall close contact, measuring head contacts with the taper hole inwall automatically.When measured workpiece bellmouth angle during less than standard angle, the dial gauge reading is less than zero, and when measured workpiece bellmouth angle during greater than standard angle, the dial gauge reading is greater than zero.During calculating, get the ultimate value of bellmouth maximum angle tolerance, the diameter range that allows to change is changed into the dial gauge value of moving up and down.
