Installing hole described in the utility model is elongated.
Rear locating piece described in the utility model is provided with the adjustment screwed hole for regulating forward and backward locating piece gap.
Prelocalization block described in the utility model and rear locating piece outline are square structure.
The lug boss of pedestal described in the utility model is provided with the material-dropping hole for unloading waste material.
The utility model first open-work and the second open-work elongated.
The utility model compared with prior art, has the following advantages and effect:
1, the utility model adopts the benchmark of forward and backward locating piece as fix vertical degree of two pieces of square structures, and offer the first boring and the second boring at the end face of forward and backward locating piece and side respectively, two borehole perpendicularities through this location are high, accurate positioning.
2, the gap between forward and backward locating piece described in the utility model is adjustable, and be therefore applicable to the boring demand of different fuel feed hole spacing, applicability is wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of pedestal described in the utility model embodiment.
Fig. 3 is the structural representation of prelocalization block, rear locating piece described in the utility model embodiment.
Fig. 4 is the structural representation of bent axle described in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1 to 4, the frock of the upper and lower oilhole of brill bent axle described in the utility model, comprise pedestal 1, prelocalization block 2, rear locating piece 3 and lining 4, the cross section of described pedestal is in " convex " font, pedestal 1 is provided with lug boss 11, prelocalization block 2 and rear locating piece 3 are equipped with fluting A, the fluting A respective protrusions portion 11 of prelocalization block 2 and rear locating piece 3 installs, the lug boss 11 of pedestal 1 locates the glide direction of prelocalization block 2 and rear locating piece 3, lug boss 11 is exactly as a slide rail, prelocalization block 2 and rear locating piece 3 are by the spacing slip of this slide rail, prelocalization block 2 and rear locating piece 3 are provided with perforate B, major axis Q1 because of bent axle Q is linear, processing operation time axle Q1 penetrates perforate B, therefore the axis of the perforate B of prelocalization block 2 and rear locating piece 3 is positioned at same straight line, lining 4 is embedded to be located in perforate B, prelocalization block 2 and pedestal 1 fixedly mount, the side of prelocalization block 2 is provided with the first boring 21 and the screwed hole 22 for locking workpiece, described lock screw 5 is threaded with screwed hole 22, the end face of rear locating piece 3 is provided with the second boring 31 and for the installing hole 32 fixing with pedestal 1, rear locating piece 3 fixedly mounts with pedestal 1 through installing hole 32 by fixed screw 6, described lining 4 is hollow tubular structures, the sidewall of lining 4 is provided with the first open-work 41, second open-work 42 and location open-work 43, first open-work 41 aims at the first boring 21, second open-work 42 aims at the second boring 31, location open-work 43 aims at screwed hole 22.
