The technical solution of the utility model is that: the utility model provides a piston inner wall taper hole processingequipment which characterized in that: the device comprises a bottom plate 1, wherein a V-shaped iron 2 is arranged on the bottom plate 1, a limiting block 3 is also arranged at one end of the bottom plate 1, a drilling mechanism is arranged at the other end of the bottom plate 1,

the drilling mechanism comprises a sliding plate 4, the sliding plate 4 is connected in a sliding groove 5 arranged on the top end surface of the bottom plate 1 in a sliding way, a positioning shaft 6 is further arranged at one end of the sliding plate 4 facing the V-shaped iron 2, two guide posts 7 are symmetrically arranged on the sliding plate 4, the two guide posts 7 are jointly connected with a lifting seat 8 in a sliding manner, meanwhile, the top ends of the two guide posts 7 are also fixedly supported with a fixed plate 9, a screw 10 is connected in the fixed plate 9 in a rotating way, the bottom of the screw 10 is connected with the lifting seat 8 in a threaded way, an annular groove 11 is arranged at the upper part of the screw rod 10, a limit bolt 12 is connected on the fixing plate 9, the end part of the limit bolt 12 is movably connected in the annular groove 11, and a handle 16 is further arranged at the top end of the screw rod 10, a motor 13 is connected to the lifting seat 8, and a taper hole cutter 14 is arranged at the working end of the motor 13.

Compared with the prior art, the utility model, have following advantage:

this kind of structural style's piston inner wall taper hole processingequipment, its simple structure, design benefit, it is rationally distributed, it is to the problem that exists in the course of working of taper hole on the traditional piston inner wall, design out a special structure, it can accurately control the cutter motion to the inner wall department of piston of processing taper hole, and realize the action of feeding of cutter through simple operation, thereby realize the processing of taper hole on the piston under the condition that does not need to rely on operating personnel proficiency and level, its appearance can effectively improve the work efficiency of piston taper hole processing, and need not be equipped with experienced operator and also can accurately accomplish the taper hole processing operation, the quality hidden danger that the human factor brought has been avoided. The processing device has the advantages of simple manufacturing process and low manufacturing cost, so the processing device has various advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 4: a piston inner wall taper hole processing device comprises a bottom plate 1 used as a foundation, a V-shaped iron 2 is arranged on the bottom plate 1, a limiting block 3 is also arranged at one end of the bottom plate 1, a drilling mechanism is arranged at the other end of the bottom plate 1,

The utility model discloses piston inner wall taper hole processingequipment's working process as follows: firstly, a piston workpiece 15 needing taper hole machining is placed in common drilling machining equipment, and a plurality of basic positioning holes are machined in the side wall of the piston workpiece 15 from outside to inside by the aid of the drilling equipment, wherein the step is a first procedure;

then, the piston workpiece 15 processed in the first process is placed on the V-shaped iron 12 of the device, the piston workpiece 15 is pushed to enable the end face of the piston workpiece to be in contact with the limiting block 3, and the piston workpiece 15 is located at a position to be processed; then an operator pushes the sliding plate 4 to enable the sliding plate 4 and all mechanisms on the sliding plate to move towards the direction of the piston workpiece 15 together, and the sliding plate stops when the positioning shaft 6 contacts with the side face of the sliding chute 5, and at the moment, the taper hole cutter 14 is just positioned above the basic positioning hole at the machining position;

an operator drives the screw rod 10 to rotate through the handle 16, and the limiting bolt 12 is clamped in the annular groove 11 formed in the screw rod 10, so that the screw rod 10 cannot move along the axial direction of the screw rod 10 and only can rotate, and the rotation of the screw rod 10 can drive the lifting seat 8 in threaded connection with the screw rod to move longitudinally, namely when the operator rotates the handle 16, the motor 13 connected to the lifting seat 8 can be driven to move longitudinally (downwards) to realize feeding action, and the feeding action is matched with the high-speed rotation of the taper hole cutter 14, so that a basic positioning hole in a machining position can be expanded into a taper hole (a larger opening of the taper hole is positioned on the inner wall of the piston workpiece 15;

after one taper hole is machined, the handle 16 is rotated reversely to lift the taper hole cutter 14, then the piston workpiece 15 is driven to rotate for a certain angle, the other basic positioning hole moves to the machining position, and the operations are repeated until all the basic positioning holes are machined into taper holes.
