The detecting device for detecting intersecting holes in engines has the advantages that predetermined relative angle, first predetermined size and second predetermined size can be determined as references according to the designed angle, relative positions and sizes of the intersecting holes, whether or not the intersecting holes are qualified can be determined clearly, and detecting is fast and accurate.

Description

The pick-up unit in crossing hole on a kind of engine

Technical field

The utility model relates to engine art, particularly the pick-up unit in crossing hole on a kind of engine.

Background technology

On engine, have a lot of groups of crossing deep holes, for example, the mail gallery holes of cylinder block is crossing with oblique oil hole, or the first hole 61 and the second hole 62 in cylinder block 6 as shown in Figure 3.In prior art, the detection method of crossing deep hole is had to two kinds, a kind of is to utilize the light of electric torch to carry out, and the electric torch of opening is placed on to the aperture in a hole, and light extends along this hole, if illumination can be observed in the aperture in another hole, illustrate that two crossing holes lead to.If one of them hole is blind hole, cannot detect in this way.

Another kind method is to utilize the iron wire prebending according to design angle to complete, and iron wire is put in a hole, if bending one end may be hooked to another hole, illustrates that two crossing holes lead to.

These two kinds of methods all cannot determine that whether the relative position in two crossing holes, crossing angle and their size be qualified, cannot determine the quality in crossing hole.

Utility model content

The utility model is in order to overcome defect in above-mentioned prior art, whether by the conduit identical with the length in hole to be measured stretched in hole, and it is qualified to utilize the more soft cable wire of walking in conduit to survey crossing angle and their size in crossing hole.

For realizing above-mentioned utility model object, the utility model provides the pick-up unit in hole crossing on a kind of engine, crossing hole comprises the first hole and the second hole, pick-up unit comprises: conduit, it is for inserting in described the first hole, one end of described conduit is provided with outlet, and the other end is provided with conduit scale and gathering sill, and described conduit is provided with pilot hole; Keeper, it is fastened in described gathering sill, the scale value of the corresponding conduit in restraint location place of described keeper represented described the first hole from the porch in this first hole the length to this first hole and the second intersection, hole; And cable wire, it penetrates in described pilot hole, and the diameter of described cable wire is configured to just pass described the second hole, and described cable wire is provided with cable wire scale.

Preferably, in technique scheme, the lateral surface of keeper is provided with angle scale.

Preferably, in technique scheme, the end of cable wire is fixed with handle.

Compared with prior art, the utlity model has following beneficial effect:

The utility model can as benchmark, can clearly judge that whether crossing hole is qualified according to the design angle in crossing hole, relative position and size definite predetermined relative angle, the first preliminary dimension, the second preliminary dimension on pick-up unit, and detection speed is fast and accurate.And pick-up unit is simple in structure, easy to operate, and production cost is lower.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.

As shown in Figure 3, cylinder block 6 is provided with two crossing holes: the first hole 61 and the second hole 62.

As shown in Figure 1 to Figure 3, on engine of the present utility model, the pick-up unit in crossing hole comprises conduit 5, conduit 5 inserts in the first hole 61 of cylinder block 6, one end of conduit 5 is provided with outlet 52, the other end is provided with the gathering sill 53 of conduit scale 51 and position and conduit scale 51 adaptations, and keeper 3 is fastened in gathering sill 53 by lock-screw 4.Conduit 5 is provided with pilot hole 54, and cable wire 2 penetrates in pilot hole 54, and cable wire 2 forms clearance fit with pilot hole 54, and cable wire 2 is configured to just pass the second hole 62.One end of cable wire 2 is fixed with handle 1, and is provided with cable wire scale.As shown in Figure 4, the lateral surface of keeper 3 is provided with angle scale, for measuring the crossing angle in two holes.

The step that uses pick-up unit of the present utility model to detect is as follows:

According to the predetermined relative location in the second hole 62 and the first hole 61 (being described the first hole from the porch in this first hole to the length of this first hole and the second intersection, hole), determine the scale value that keeper 3 is located at conduit 5, and keeper 3 is fixed in the gathering sill 53 of conduit 5 by lock-screw 4;

Conduit 5 is inserted in the first hole 61 of cylinder block 6, the end face of keeper 3 is connected on the end face of cylinder block 6;

According to the predetermined relative angle in the first hole 61 and the second hole 62, by observing the angle scale 31 of keeper 3, pick-up unit is rotated to predetermined relative angle with respect to cylinder block 6, make the direction of outlet 52 of conduit 5 consistent with the predetermined direction in the second hole 62;

By handle 1 by the pilot hole 54 of cable wire 2 propulsion bulbs 5, observe the scale value of the cable wire at conduit outer face place, if cable wire 2 enters the preliminary dimension that the length of pilot hole 54 is greater than cable wire 2, represent that cable wire 2 enters the second hole 62 by the outlet 52 of conduit 5, judge that the size in relative position, relative angle and the first hole 61 and the second hole 62 in the first hole 61 and the second hole 62 is qualified; Otherwise judge that crossing hole is defective.

Disclosed is above only a specific embodiment of the present utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
