Description
Technical field
The utility model belongs to automobile gas exhausting manifold branch manufacture field, particularly relates to a kind of exhaust manifold sensor mounting hole chamfering tool.
Background technology
Exhaust manifold is the vitals of automobile exhaust system, and it is mainly used in exhaust.In order to detect capacity, designer devises a sensor in the end of exhaust manifold at present, and this sensor is arranged in sensor mounting hole, and the aperture of sensor mounting hole with an angle, needs a kind of chamfering tool of specialized designs for this reason.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of exhaust manifold sensor mounting hole chamfering tool, for exhaust manifold is clamping by this frock, so that chamfering after boring.
The technical solution of the utility model is as follows: a kind of exhaust manifold sensor mounting hole chamfering tool, it is characterized in that: comprise horizonal base plate (1) and mistake proofing screw (4), wherein horizonal base plate (1) is rectangular slab, its thickness is 2-4mm, one piece of location-plate (2) is installed with at horizonal base plate (1) end face, this location-plate upper end towards the rear end of horizonal base plate (1), and forms inclined angle alpha, and 5 °≤α≤60 °; Described location-plate (2) rear side left and right has one piece of stiffener (3) side by side, this stiffener leading flank and location-plate (2) are welded and fixed in plate face afterwards, and bottom surface and described horizonal base plate (1) end face of stiffener (3) are welded and fixed; The number of described mistake proofing screw (4) is one, this mistake proofing screw is vertically fixed on the upper right quarter of described location-plate (2) front face, and the surface roughness of location-plate (2) front face is 0.6-3.2mm, and the length of mistake proofing screw (4) is 8-15mm.
In technique scheme, horizonal base plate of the present utility model (1) is bolted on the workbench of upright drill by T-shaped.During chamfering, first the front face of the faying face of exhaust manifold and location-plate (2) is close to, the positioning end of exhaust manifold is near mistake proofing screw (4), and with hand, exhaust manifold is pressed on location-plate (2), finally by drill bit, chamfering is carried out to the sensor mounting hole that exhaust manifold has bored.Further, stiffener (3) effectively can strengthen structural strength.
Adopt above technical scheme, the utility model can conveniently, effectively be located exhaust manifold, to sensor mounting hole chamfering, and operative is simple, laborsaving, frock convenient disassembly.
In the present case, the numerical value of described α is 50 °.
For the ease of drawing materials, the material of described horizonal base plate (1) and location-plate (2) is Q235.
Beneficial effect: the utility model can conveniently, effectively be located exhaust manifold, to sensor mounting hole chamfering, and operative is simple, laborsaving, frock convenient disassembly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A direction view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of exhaust manifold sensor mounting hole chamfering tool, is formed primarily of horizonal base plate 1, location-plate 2, stiffener 3 and mistake proofing screw 4.Wherein, horizonal base plate 1 is rectangular slab, and its thickness is 2-4mm, and horizonal base plate 1 is bolted on the workbench of upright drill by T-shaped.The material of horizonal base plate 1 and location-plate 2 is Q235, and this two boards is by being welded and fixed.Be installed with one piece of location-plate 2 at horizonal base plate 1 end face, this location-plate 2 upper end towards the rear end of horizonal base plate 1, and forms inclined angle alpha, and 5 °≤α≤60 °.In the present case, the numerical value of α is preferably 15 °, 20 °, 30 °, 45 ° and 50 °.
On rear side of described location-plate 2, left and right has one piece of stiffener 3 side by side, and this stiffener 3 leading flank and the rear plate face of location-plate 2 are welded and fixed, and bottom surface and horizonal base plate 1 end face of stiffener 3 are welded and fixed.The number of mistake proofing screw 4 is one, and this mistake proofing screw 4 is vertically fixed on the upper right quarter of location-plate 2 front face.The surface roughness of location-plate 2 front face is 0.6-3.2mm, so just can effectively locate by exhaust manifold.The length of mistake proofing screw 4 is 8-15mm, the reliably mistake proofing of such guarantee, and the effect of mistake proofing screw 4 matches with exhaust manifold, thus normally locate exhaust manifold.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
