Detailed Description
The invention is further described with reference to the following specific drawings and examples.
As shown in fig. 1 to 3, the present embodiment specifically relates to a tool for drilling a drill jig for drilling a circumferential surface of a water pump motor end cover with a center height of H400 or H500, which includes a radial drilling machine 17 and a drilling machine workbench 11, wherein an adjustable spindle 8 is fixed on a top surface of the drilling machine workbench 11; the outer end of the rear part of the (axial) adjustable mandrel 8 is sleeved with a seamless steel pipe 10, the outer side of the radial surface of the seamless steel pipe 10 has two functions through a lifting ring screw 9, and the tool can play a role in lifting and connecting an L-shaped position reference plate 18; the outer circle of the front part of the adjustable mandrel 8 is provided with a rolling bearing 7, and the periphery of the rolling bearing is provided with a roller 4; the front end face of the adjustable mandrel is provided with a shaft end baffle plate 2 through an assembly part 6 of the shaft center, and the lower part of the shaft end baffle plate 2 is provided with a positioning part 3.
As a further improvement, the adjustable mandrel 8 in the adjusting axial direction is fixed on the drill press workbench 11 through a bolt and an opening base plate 16 according to the thickness of the workpiece.
As a further improvement of the utility model, the roller 4 is a nylon roller.
As the further improvement of the utility model, the rolling bearing 7 and the stepped seam of the adjustable mandrel are provided with the elastic retainer ring 5 for the shaft.
Firstly, according to the figures 1 and 2, all parts are assembled, namely the adjustable core shaft 8 is assembled in the seamless steel pipe 10, the two open base plates 16 can be respectively and firmly welded by electric welding according to the positions of the trapezoidal grooves of the corresponding drilling machine working platform 11, and according to the schematic diagram, the two open base plates are fixed on the upper surface of the drilling machine working platform 11 by using T-shaped bolts 12, flat pads, spring washers, nuts and the like. Then two sets of rolling bearings 7 are arranged in the nylon roller 4 according to the requirements of the drawing (corresponding lubricating grease is added in the inner cavity of the rolling bearing 7), and then the assembled parts are assembled at the left end of the adjustable core shaft 8 and are fixed by the elastic retainer ring 5 for the shaft;
after the workpiece 1 is hung and a specific position is determined by the position reference plate 18, the shaft end baffle plate 2 is fixed at the shaft end of the adjustable mandrel 8 by the hexagon socket head cap screw 6, and after the final drilling or tapping position is finely adjusted, the positioning is fixed by the positioning screw 3.
During specific operation, the inner hole of the motor end cover of the motor H400/H500 water pump which is scribed by a fitter and needs to be processed is pressed on the nylon roller 4 by a corresponding lifting appliance, the workpiece 1 is initially fixed on the side surface of the drilling machine workbench 11 by the shaft end baffle 2 and the hexagon socket head cap screw 6, and then final adjustment is carried out according to the position reference plate 18. And simultaneously the radial drilling machine 17 is adjusted to enter a machining state. When the direction needs to be changed for machining, the corresponding wrench needs to slightly loosen the socket head cap screw 6, then the excircle of the workpiece 1 is slightly rotated to the position needing drilling by the hand, and the socket head cap screw 6 is screwed by the corresponding wrench for fixing after the position reference plate 18 (the vertical center line mark is carved at the sharp corner of the V-shaped notch and is painted yellow, so that the line drawn by naked eyes and the workpiece 1 can be conveniently aligned to determine whether the line is overlapped or not). And circulating the way until the whole processing is finished. Then, for the sake of safety, the workpiece is pre-tightened and hung by the hanger, then the socket head cap screws 6 are unscrewed by the corresponding plates and are detached together with the shaft end baffle 2, and the workpiece 1 is lifted to leave and reasonably placed.
Because the nylon roller 4 (internally provided with two sets of rolling bearings 7) is designed, the whole workpiece is easy and flexible in the rotating process. And the adjustable telescopic mandrel 8 is designed to be freely and freely matched with the inner diameter of the seamless steel pipe 10 according to the width L of the workpiece 1, and the workpiece 1 is locked by a suspension ring screw 9 after being positioned, so that no axial displacement occurs in the machining process of the workpiece 1. The processing quality is ensured. And because the nylon roller 4 is designed, the machined inner hole surface is not damaged when the workpiece 1 is loaded and unloaded. Therefore, the whole process of installing, adjusting and drilling the workpiece is more labor-saving, convenient and safe.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
