Abstract

The utility model discloses a numerical control drilling machine for piston dowel holes, which is provided with a servo rotary mechanism and a piston jacking mechanism coaxially and oppositely arranged. A positioning clamp is arranged on a rotary shaft of the servo rotary mechanism, a piston is fixed into the positioning clamp, a jacking pin of the piston jacking mechanism is aligned to the end of the piston, a single-shaft servo feeding unit is arranged on the side of the servo rotary mechanism, and the moving direction of the single-shaft servo feeding unit is parallel to the axis of the servo rotary mechanism. A drilling device is arranged on the single-shaft servo feeding unit and comprises a drilling spindle, and a drilling tool is arranged at the end of the drilling spindle connected with a power mechanism. The drilling tool is aligned to a dowel hole processing position of the piston, the piston is driven by the servo rotary mechanism to rotate and be positioned at an optional angle, and various dowel holes on the piston can be processed by means of the drilling tool fixed on the single-shaft servo feeding unit after precision feeding and moving of the single-shaft servo feeding unit. The numerical control drilling machine is suitable for processing piston dowel holes in various specifications, and drilling precision and drilling efficiency can be improved.

Description

Numerical control piston pin hole drilling machine
Technical field
The utility model relates to the drilling hole machine tool technical field, relates in particular to a kind of numerical control piston pin hole drilling machine.
Background technology
As shown in Figure 1, there are two pin holes 51 to need processing on the piston 5, because these two pin holes 51 are positioned at not on the piston face of cylinder on the same one side.Prior art can't utilize existing drilling hole machine tool to process simultaneously, can only at twice the fixing back of piston clamping be processed on drilling machine, the clamping handling ease causes two angles between the pin hole inaccurate at twice, and since on the piston distance and the angle between two pin holes plurality of specifications is arranged, when processing different angles pin hole, need to change different clamping positioning tools, so existing piston pin hole machining accuracy is low, working (machining) efficiency is also low.
Summary of the invention
The utility model purpose provides a kind of borehole accuracy and the high numerical control piston pin hole drilling machine of efficient.
The utility model adopts following scheme to realize: numerical control piston pin hole drilling machine, it is provided with frame, frame is provided with the servo rotating mechanism and the piston jacking mechanism of coaxial and positioned opposite, the rotating shaft of servo rotating mechanism is provided with positioning fixture, piston is fixed in the positioning fixture, the thimble of piston jacking mechanism is aimed at pistons end, the side of servo rotating mechanism is provided with single shaft servo feed unit, the direction of motion of single shaft servo feed unit is parallel with servo rotating mechanism axis, single shaft servo feed unit is provided with drilling equipment, drilling equipment comprises drill spindle, the axle head of drill spindle is provided with drilling tool, drill spindle connects actuating unit, and drilling tool is aimed at a pin hole Working position of piston; Add man-hour, the thimble of piston jacking mechanism holds out against pistons end, actuating unit drives drill spindle and drilling tool rotates, make the drilling tool feeding process first pin hole, processing back drilling tool is return, servo rotating mechanism drive rotating shaft and on piston rotation, the unit feeding of single shaft servo feed makes drilling tool aim at second pin hole Working position, drilling tool is second pin hole of feeding processing again.
Described drill spindle adopts the high-speed drilling main shaft.
Described drilling tool is an alloy bit.
The beneficial effects of the utility model are: adopt said structure, control servo rotating mechanism by the digital control system of being furnished with in the lathe and drive piston rotation fixed thereon, realize the pin hole processing of diverse location on the piston, digital control system can be controlled servo rotating mechanism drive piston rotation and be positioned arbitrarily angled, single shaft servo feed unit accurately feeding moves, and the drilling tool that is fixed on the single shaft servo feed unit is processed the different pin holes on the piston; When distance between the pin hole and angle change, only need in digital control system, to import different parameters and just can realize, be fit to the piston pin hole of processing plurality of specifications.The utility model adopts numerically-controlled precise control to improve borehole accuracy and drilling efficiency, reduces the piston pin gimlet for nail hole time, can cut down finished cost.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is further elaborated:
Fig. 1 is the structural representation of the utility model piston pin hole;
Fig. 2 is the schematic top plan view of the utility model numerical control piston pin hole drilling machine.
The specific embodiment
As shown in Figure 2, the utility model is provided with frame 1, frame 1 is provided with the servo rotating mechanism 2 and the piston jacking mechanism 3 of coaxial and positioned opposite, the rotating shaft 21 of servo rotating mechanism 2 is provided with positioning fixture 4, piston 5 is fixed in the positioning fixture 4, the thimble 31 of piston jacking mechanism 3 is aimed at piston 5 ends, the side of servo rotating mechanism 2 is provided with single shaft servo feed unit 6, the direction of motion of single shaft servo feed unit 6 is parallel with servo rotating mechanism 2 axis, single shaft servo feed unit 6 is provided with drilling equipment 7, drilling equipment 7 comprises drill spindle 71, the axle head of drill spindle 71 is provided with drilling tool 72, drill spindle 71 connects actuating unit 73, and drilling tool 72 is aimed at pin hole 51 Working positions of piston 5; Add man-hour, the thimble 31 of piston jacking mechanism 3 holds out against piston 5 ends, actuating unit 73 drives drill spindle 71 and drilling tool 72 rotates, make drilling tool 72 feedings process first pin hole 51, processing back drilling tool 72 is return, servo rotating mechanism 2 drive rotating shafts 21 and on piston 5 rotate, 6 feedings of single shaft servo feed unit make drilling tool 72 aim at second pin hole 51 Working position, drilling tool 72 is second pin hole 51 of feeding processing again.
Described drill spindle 71 adopts the high-speed drilling main shaft.
Described drilling tool 72 is an alloy bit.
The utility model not only can the machining piston pin hole, by changing cutter and anchor clamps, can also process other similar workpiece of cutting.
