Drawings
FIG. 1 is a sectional view of a movable guide sleeve mounting structure of a special machine for drilling a rough surface and an oblique oil hole of an air cylinder body according to an embodiment of the utility model;
in the figure: 1. The device comprises a workpiece 2, a frame 3, a movable guide sleeve 4, a deflector rod 5, a transmission shaft 6 and an intermediate sleeve.
Detailed Description
The utility model will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The special machine for drilling the rough surface and the oblique oil hole of the cylinder block comprises a machine tool body, a drill bit, a machine frame 2 and a middle sleeve 6, wherein a transmission shaft 5 is arranged on the machine frame 2, the transmission shaft 5 is connected with a shifting rod 4, one end of the shifting rod 4 is inserted into a movable guide sleeve 3 and movably connected with the movable guide sleeve, the movable guide sleeve 3 is slidably sleeved on the middle sleeve 6, the drill bit is slidably inserted into the movable guide sleeve 3, and the tail end of the movable guide sleeve 3 is matched and matched with a surface where a hole to be processed is located.
When the utility model is implemented, the implementation key points are as follows:
before a workpiece is machined, firstly, the oil cylinder drives the transmission shaft 5, the transmission shaft 5 drives the deflector rod 4 to stir the movable guide sleeve 3, the movable guide sleeve 3 slides forwards in the fixed middle sleeve 6 until the front end surface (convex surface) of the movable guide sleeve is tightly attached to the workpiece 1, the movable guide sleeve does not move, then, a drill bit starts to drill through the movable guide sleeve 3, and when the drill bit is about 5mm deep, the drill bit stops drilling. At this moment, the oil cylinder drives the transmission shaft 5, the transmission shaft 5 drives the deflector rod 4 to deflect the movable guide sleeve 3 in the opposite direction, the movable guide sleeve 3 moves backwards, the movable guide sleeve 3 stops moving when the front end face of the movable guide sleeve 3 is about 10mm away from the workpiece 1, the drill bit restarts drilling, the workpiece 1 is withdrawn after the drilling is finished, and the movable guide sleeve 3 also retracts to the original position.
Attention is paid to: the movable guide sleeve 3 slides forwards along the fixed middle sleeve 6 until the front end surface (convex surface) of the movable guide sleeve is tightly attached to the workpiece 1 and does not move, and the drilling depth of the drill bit is 5mm so that the drill bit can be positioned firstly and does not slide on the concave surface of the workpiece 1 after being drilled to a certain depth; the movable guide sleeve 3 stops moving when moving backwards to the position where the distance between the front end face of the movable guide sleeve 3 and the workpiece 1 is about 10mm, so that the drill bit restarts drilling, and the movable guide sleeve is used for conveniently removing chips, and the scheme for drilling the rough surface hole is more reasonable.
In an embodiment of the present application, the end of the movable guide sleeve 3 is provided with an inclined surface, and the inclined surface is overlapped with the surface where the hole is located after contacting, so that the hole processing of the inclined surface is realized, and the hole processing can also be realized under the condition that the surface is a rough surface.
In one embodiment of the present application, the end of the movable guide sleeve 3 is provided with a spherical surface, and the spherical surface is embedded and overlapped after contacting with the surface where the hole is located, so as to realize hole processing of the spherical concave surface.
In an embodiment of the present application, the end of the movable guide sleeve 3 is provided with a concave surface, and the concave surface is overlapped with the surface where the hole is located after contacting, so as to realize hole machining of the convex spherical surface.
In an embodiment of the application, the transmission shaft 5 is driven by the oil cylinder to rotate forwards or backwards, the oil cylinder is used for driving, the implementation is facilitated, driving pieces are reduced, the advantage that the machine tool is provided with the hydraulic cylinder is utilized, and the cost is reduced.
