Description
Technical field
The utility model relates to a kind of frock, the oblique water hole of particularly a kind of marine diesel piston head cooling water cavity processing tool.
Background technology
The piston head of diesel engine is in manufacture process; Need process (as shown in Figure 1) to the oblique water hole of cooling water cavity; The traditional processing frock is a special tooling platform that the fixed angle inclined-plane is arranged; The external diameter of piston head is supported with two fixed rotating shafts, make it can do rotation, reach the purpose of centering.Being operated in need rule by pincers worker when confirming position, oblique water hole of this structure operated; After having bored a hole at every turn; Need unclamp the pressure spanner, move by hand piston head and it is rotated to the position in next hole and adjust repeatedly, carry out rotary cut processing after the clamping once more.The man-hour that on frock adjustment clamping, just needs labor like this.Especially in the process of manually pulling the rotation centering,, rely on the line centering fully, often cause the oblique water hole Working position precision between outer water cavity hole and the interior water cavity not reach requirement because workpiece does not have circumferential positioning reference.Utilize this traditional frock to process, complex operation not only, inefficiency, but also do not reach required precision, therefore need a kind of novel frock that can address the above problem now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology; Propose a kind of simple in structure; Design ingenious; Can circumferentially adjust the workpiece (piston head of diesel engine) of clamping easily and efficiently, and can guarantee the oblique water hole of the marine diesel piston head cooling water cavity processing tool of machining accuracy.
The technical solution of the utility model is: the oblique water hole of a kind of marine diesel piston head cooling water cavity processing tool; It is characterized in that: described frock comprises substrate 1; On substrate 1, be connected with tilt flat plate 2; One end of tilt flat plate 2 is connected through hinges 3 with substrate 1, and it is hinged to tune whole leading screw 4 about the other end and double end, and the other end that tunes whole leading screw 4 about double end is connected with substrate 1 through hinges 3 equally; Tilt flat plate 2 is provided with circular groove 5; On the circumference of the rotating disc 6 that matches with circular groove 5 equidistance be provided with 36 dowel holes 7, tilt flat plate 2 is provided with two locating holes 8 that match with dowel hole 7, the angle between two lines in these two locating holes 8 and circular groove 5 centers of circle is the integral multiple of 10 degree; Be furnished with alignment pin 9 mutually with dowel hole 7 and locating hole 8, also be provided with set bolt 10 at the circle centre position of circular groove 5 and rotating disc 6.
The utility model is compared with prior art, has following advantage:
The oblique water hole of the marine diesel piston head cooling water cavity processing tool of this kind of version; It is simple in structure; Design ingeniously, it creatively designs the rotating disc that circumference is provided with 36 dowel holes of equidistance to the in use existing problem of processing tool in the oblique water hole of existing piston head of diesel engine cooling water cavity; And on fixed tilt flat plate, be provided with the locating hole that matches with these dowel holes; This structure is equipped with alignment pin again, just can realize the adjustment of some fixed angles fast and accurately, and then realizes on blank, processing accurately and rapidly the purpose in oblique water hole.And the manufacture craft of this frock is simple, and is cheap for manufacturing cost, therefore we can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.

The specific embodiment
Below with the specific embodiment of accompanying drawings the utility model.Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: the oblique water hole of a kind of marine diesel piston head cooling water cavity processing tool; It comprises a substrate 1 as the basis; Be connected with tilt flat plate 2 in the upper end of substrate 1; One end of this tilt flat plate 2 links to each other through hinges 3 with substrate 2, and the other end then with about double end tunes whole leading screw 4 to hinged, and the other end that tunes whole leading screw 4 about double end is connected with substrate 1 through hinges 3 equally; Through tuning whole leading screw 4 about the adjustment double end, adjust the angle of inclination of tilt flat plate 2; Tilt flat plate 2 is provided with circular groove 5; Be provided with rotating disc 6 with this circular groove 5 matches; Rotating disc 6 can rotate in circular groove 5, and on the circumference of rotating disc 6, goes back 36 dowel holes 7 that are provided with of equidistance, on tilt flat plate 2, then is provided with two and can overlaps and measure-alike locating hole 8 with these dowel holes 7; Two line shapes between these two locating holes 8 and circular groove 5 centers of circle in an angle, and the angle of this angle be 10 the degree integral multiple; Be furnished with alignment pin 9 mutually with dowel hole 7 and locating hole 8, also be provided with set bolt 10 at the home position place of circular groove 5 and rotating disc 6.
The course of work of the oblique water hole of the marine diesel piston head cooling water cavity processing tool of the utility model embodiment is following: at first blank is fixedly connected on the rotating disc 6 through set bolt 10 that (blank and set bolt 10 direct-connected parts further can removed in the process; Therefore this connection can not influence final workpiece processing); Holing when needs adds man-hour, through tuning whole leading screw 4 about the adjustment double end, adjusts the angle of inclination of tilt flat plate 2; After treating that angle adjustment is good; The processing (as shown in Figure 2) of holing after the hole completion of processing, is pulled up the alignment pin 9 of cross-under in dowel hole 7 and locating hole 8; According to the five equilibrium quantity of hole on circumference of required processing, decide the quantity of the dowel hole of being walked in rotating disc 6 rotation processes 7.
As to work as the inclined hole of being processed be timesharing such as 6 on circumference; After processing first inclined hole; After only need rotating disc 6 being rotated 36/6=6 dowel hole 7, alignment pin 9 inserted again fix in dowel hole 7 and the locating hole 8 and locate, get final product holing to process; 5 times so repeatedly, just can realize the processing of the inclined hole of 6 five equilibriums on the circumference.
The effect that is arranged on two locating holes 8 on the tilt flat plate 2 is to help rotating disc 6 centering apace, in the process of rotating disc 6 rotations, only needs to observe through dowel hole 7 locating hole 8 at its rear, and whether the position that just can judge rotation is accurate; Because the central angle angle between per two adjacent dowel holes 7 is 10 degree, therefore the central angle angle between two locating holes 8 is that the integral multiple of 10 degree gets final product.
