Abstract

The utility model discloses an inclined hole position detector, being characterized in that the detector uses a length bar to penetrate a cone block so as to insert the length bar into an inclined hole of a workpiece; and at the same time two indicators are respectively corresponding to the horizontal direction and the vertical direction of the inclined hole. Due to use of the above structure, the inclined hole position detector has the advantages that 1, the inclined hole position detector can accurately and quickly detect the inclined hole position of the workpiece; 2, as the indicators are used as the detection tools, the positional deviation for the inclined hole can be visually read, and the incorrect position can be corrected when the workpiece processes the inclined hole; and 3, the inclined hole position detector is simple in structure and convenient to detect.

Description

A kind of inclined hole position detecting device
Technical field
The utility model relates to field of machining, particularly a kind of inclined hole position detecting device.
Background technology
In the machining of auto parts and components, hydraulic pressure components and parts, have all to have inclined hole on a lot of workpiece, the inspection of inclined hole position is relatively more difficult when making these parts in enormous quantities.
Usually all be to guarantee,, need make regular check on or the part workpiece is inspected by random samples,, can not guarantee that workpiece to be machined inclined hole position 100% is qualified even so also occur the omission phenomenon easily to anchor clamps simultaneously in order to guarantee that processing work is qualified with technology, frock.
A kind of novel pick-up unit is provided, thus can be rapidly, exactly the workpiece inclined hole to be carried out quality inspection be the problem that prior art need solve.
The utility model content
The utility model technical matters to be solved is a kind of inclined hole position detecting device to be provided, with the purpose that realizes the workpiece inclined hole is carried out quality inspection fast.
For solving the problems of the technologies described above; The technical scheme of the utility model is; A kind of inclined hole position detecting device is characterized in that: described pick-up unit is to insert in the inclined hole of workpiece after length bar passes the centrum piece, is provided with two indicators horizontal direction and the vertical direction of corresponding inclined hole respectively simultaneously.
The angle of described cone piece cone angle is the twice at inclined hole oblique angle; Cone piece outside diameter is 1.5~2 times of inclined hole diameter; Cone tile height 10~15mm adds the data that indicator obtains, and through calculating inclined hole is detected.
Described indicator is installed on the dial framework, and the bottom of dial framework is fixed with block.
Described workpiece bottom is provided with block, thereby the position of workpiece is fixed.
A kind of inclined hole position detecting device, owing to adopt said structure, this pick-up unit has the following advantages: 1, can accurately, promptly carry out the inspection of workpiece inclined hole position; 2, owing to used indicator, the position deviation of inclined hole can be intuitively read, the out of position of workpiece when the processing inclined hole can also be corrected as checking tool; 3, simple in structure, easy to detect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation;
Fig. 1 is the structural representation of a kind of inclined hole position detecting device of the utility model;
Fig. 2 is the partial structurtes synoptic diagram of a kind of inclined hole position detecting device of the utility model;
Fig. 3 is second kind of application structure synoptic diagram of a kind of inclined hole position detecting device of the utility model;
Fig. 4 is that second kind of a kind of inclined hole position detecting device of the utility model used the partial structurtes synoptic diagram;
In Fig. 1-2,1, block; 2, length bar; 3, indicator; 4, workpiece; 5, centrum piece.
Embodiment
The utility model purpose is the deficiency that has now in processing, the inspection in order to overcome, and adopts the length bar 2 of suitable configuration, the dial framework of band indicator 3 and the combination of reference gauge, and workpiece is positioned, thereby can carry out the quality inspection of workpiece inclined hole rapidly, exactly.
The utility model is that length bar 2 passes in the inclined hole of centrum piece 5 back insertion workpiece 4, is provided with two indicators 3 horizontal direction and the vertical direction of corresponding inclined hole respectively simultaneously.
The angle of cone piece 5 cone angles is the twice at inclined hole oblique angle; Cone piece 5 outside diameters are 1.5~2 times of inclined hole diameter; Cone piece 5 height 10~15mm adds the data that indicator 3 obtains, and through calculating inclined hole is detected.
Indicator 3 is installed on the dial framework, and the bottom of dial framework is fixed with block.Workpiece 4 bottoms are provided with block, thereby the position of workpiece 4 is fixed.
The utility model is chosen length bar 2 and is inserted in the tested inclined hole; And make length bar 2 insertion portions and inclined hole tolerance clearance minimum; With workpiece 4 appropriate location; Carry out the inspection of the horizontal direction size and the vertical direction size of hole site as required with the dial framework of two band indicators 3, proofread zero-bit with reference gauge before indicator 3 uses.
Shown in Fig. 1-2, cone piece 5 cone angles 2 α are the twice at inclined hole oblique angle, and cone angle tolerance is taken as 1/2~1/3 of workpiece 4 inclined hole oblique angle tolerance values; Cone piece 5 outside diameters are taken as 1.5~2 times of tested inclined hole diameter, and tolerance is got 1/5~1/10 of seized size minimal tolerance value; Cone piece 5 height 10~15mm.
For example, in order to check the seized A of being of a size of ± 0.05, the inclined hole of B ± 0.02, through length bar 2 convert X into, the Y value realizes, that is:
X=A+ab?, ab=D/(4sinα);
Y=B+ac, ac=0.5×D×cosα;
Calculate X, Y value back only need with indicator on numeral whether can draw the inclined hole that is detected after comparing qualified.
Shown in Fig. 3-4, be examined and be of a size of E ± 0.01, the key dimension of length bar 2 is: d1: insert diameter; D2: the cone end diameter (d2>d1); H: cone height; 2 α: cone angle; In this example, 2 α=2 * (90 °-β °), the manufacturing tolerance of d2, H is got 1/5~1/10 of measured size tolerance, and the manufacturing tolerance of cone angle 2 α is pressed workpiece oblique angle tolerance value or its 1/2 and is got final product.
Size conversion Y value: Y=E+H+0.5 * d2 * ctg α.
Calculate Y value back only need with indicator on numeral whether can draw the inclined hole that is detected after comparing qualified.
Inspection inclined hole position in batch process; Can be according to the concrete condition of workpiece 4 inclined hole positions; With the length bar 2 of different profiles, the dial framework and the reference gauge of band indicator 3, accurately, promptly carry out the inspection of workpiece 4 inclined hole positions, the utility model is owing to used indicator 3 as checking tool; The position deviation of inclined hole can be intuitively read, the out of position of workpiece when the processing inclined hole can also be corrected.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as the various improvement of having adopted the utility model technical scheme to carry out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
