Description

The cylindrical conicity measurement mechanism
Technical field
The utility model relates to a kind of measuring appliance, relates in particular to the conicity measurement mechanism that uses when being applicable to the processing of major diameter cylindrical tapering, check.
Background technology
At present, in machining, the measurement of workpiece tapering has two kinds of methods usually, and promptly gauge grinds face method and sine gauge method.Whether gauge grinds the face method, tints on the workpiece conical surface exactly, with the circular cone socket gauge bedding-in of standard, judges workpiece tapering and size whether in the range of size of regulation by the coloring degree of gauge and the workpiece conical surface, qualified with definite workpiece.Adopt this method must make the precise gauge of required tapering in advance; Workpiece is easily by plucking and scuffing simultaneously, and testing result depends on operator's technical merit to a great extent, and error is big; And when measuring large diameter tapering, the manufacturing of gauge and use be difficulty quite.The sine gauge method is about to workpiece and places on the measuring table, carries out taper measurement with sine gauge or slip gauge, adopts this method can not random measurement, and workpiece is difficult for fixingly, and detection efficiency is low.
Use conventional methods the detection needs when being difficult to satisfy on-the-spot batch process the in batches, especially when processing major diameter tapering,, add the very difficult machining precision that guarantees in man-hour owing to lack suitable survey instrument, therefore need a kind of suitable produced on-site, check, easy to operate tapering pick-up unit.
The utility model content
It is a kind of easy and simple to handle reliable that technical problem to be solved in the utility model is to provide, the cylindrical conicity measurement mechanism that can use at random.
The technical solution of the utility model is as follows: a kind of cylindrical conicity measurement mechanism, and transverse slat and support are perpendicular, and an end of transverse slat is fixedlyed connected with the lower end of support, at the other end of transverse slat retainer is installed, and the top of this retainer offers the V-type groove; Be provided with parallel with it differential head bearing above described transverse slat, an end of this differential head bearing is installed two differential heads side by side, and the other end of differential head bearing is connected on the support, and differential head bearing can move up and down along support.
When the utility model is used to measure the cylindrical tapering, regulate the height of differential head bearing on support earlier, V-type groove with retainer is placed on the workpiece conical surface then, make the V-type groove be close to surface of the work, regulate two differential heads more respectively, the gauge head of differential head is just contacted with surface of the work,, just can obtain the difference in height that two differential heads are surveyed by differential head reading.Because the centre distance of two differential heads is fixed, therefore can obtain the tangent value of the cone angle of the workpiece of surveying, thereby can calculate the tapering of workpiece.
Processing for convenience offers square three-way groove at the bottom land of above-mentioned retainer V-type groove.
The bottom of above-mentioned retainer is fixed by an end of screw and transverse slat, and the other end of transverse slat snaps in the square draw-in groove of support lower end, also passes through screw retention.Above structure connects reliable, and easy disassembling can be changed the retainer of different V-type grooves as required.
For the ease of assembling and regulate, above-mentioned support is installed in the square draw-in groove on the differential head bearing, fixes by milled screw between support and the differential head bearing, and this milled screw is located in the strip hole that its length direction of support upper edge offers.
For simplified structure, help installing, above-mentioned differential head bearing is

Shape, the crosspiece of this differential head bearing is connected with support by milled screw, respectively has a mounting hole at the two ends of the vertical section of differential head bearing, fixing assembling differential head in this mounting hole, the lock-screw that wears perpendicular to this mounting hole is tight with the described differential crown.
In order to improve the accuracy of measurement, the gauge head of above-mentioned differential head bottom is spherical measurement face.
Beneficial effect: the utility model overcome need when adopting classic method to measure tapering accurate ring gauge, can not random measurement limitation; This utility model compact conformation, easy to operate, measurement range is big, is specially adapted to the measurement of major diameter tapering, can accurately reflect the workpiece tapering; Use this device to carry out random measurement, in time detect the workpiece tapering, make the operator can in time adjust cutting-tool angle, guarantee the machining precision of workpiece workpiece.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model partly is made of retainer 1, transverse slat 2, support 3, differential head bearing 4, differential head 5 and screw etc.Wherein differential head bearing 4 and transverse slat 2 are up and down and are arranged in parallel, and both are all perpendicular with support 3.One end of described transverse slat 2 is fixed by the bottom of pan head screw and retainer 1, offer V-type groove 1a at the top of retainer 1, the size of V-type groove 1a determines according to the circular cone size of workpiece for measurement, and the bottom land of V-type groove 1a offers square three-way groove 1b, so that processing.The other end of described transverse slat 2 snaps in the square draw-in groove of support 3 lower ends, fixes by pan head screw.
As can be known, its length direction offers strip hole 3a in support 3 upper edges from Fig. 1, Fig. 2, and this strip hole 3a extends to the upper end from the middle and lower part of support 3 always.Described differential head bearing 4 is
