Abstract
The utility model relates to a telescopic boring head for processing a circular box type inner cavity. The telescopic boring head is provided with a cutter and a cover board, wherein a boring body is positioned through a seam allowance and is connected to a boring machine through a bolt; a main shaft is arranged in the boring body through two thrust bearings and a locking nut; a clutch is arranged on the main shaft; a circular slot is formed in the outer diameter of the boring body; a supporting plate is embedded into the circular slot; an external nut is connected with the supporting plate and an internal screw sleeve; a pressing rod is inserted into a sliding rod shaft hole and an opening slot of the main shaft and is encircled by a planar bearing and the internal screw sleeve; a sliding rod shaft is arranged in an inner hole of the main shaft; a sliding block box is arranged in a sliding window of the main shaft; the cutter is arranged in the sliding block box and is fixed by a screw; and an inclined slot of the sliding rod shaft is coupled with an inclined slot of the sliding block box. The telescopic boring head can extend into an inner cavity of a water cavity to work; the size of the inner cavity and the surface smoothness can be well guaranteed; the requirement for improving the performance of an engine is met; and the telescopic boring head is convenient to operate and high in machining efficiency.
Description
Technical field
The utility model relates to a kind of flexible boring head of processing circular box inner chamber.
Background technology
In the automobile engine production and processing; The cylinder hole water cavity of wet-sleeve cylinder body is to be formed by the loam core casting; Inner chamber is irregular, rough, scab; Cause that thus the cool cycles water resistance is big, flow is inconsistent, defective such as that engine is prone to is overheated, the cylinder sleeve piston is easy to wear influences engine performance.And traditional boring machine generally do not have depth-feed mechanism, so just can not process the water cavity inner chamber.
Summary of the invention
The purpose of the utility model is: provide a kind of and be installed on the boring machine, be used for the inner chamber processing in circular box hole, add and stretch out cutter processing inner chamber man-hour, during withdrawing the flexible boring head of the circular box inner chamber of the processing of cutter indentation withdrawing.
It is achieved in that it is provided with cutter and cover plate, and the boring body is connected on the boring machine through seam location and bolt.Main shaft is assemblied in the boring body through two thrust bearings and locking nut; Clutch device is on main shaft; Processed a circular groove on the external diameter of boring body, in support plate is embedded in; Outer nut and support plate, internal thread cover are connected, and depression bar inserts in the slide bar axis hole in the open slot with main shaft, are put down with spherical bearing and the encirclement of interior silk braid, and sliding pole axis is packed in the endoporus of main shaft; Slide block is box-packed goes in the sliding window of main shaft, and cutter is contained in the slide block box and is screwed, the skewed slot coupling of the skewed slot of sliding pole axis and slide block box.
The advantage of the utility model is: can put in the processing of water cavity inner chamber, guarantee inner cavity size and surface smoothness well, reach and improve the engine performance requirement.Easy to operate, working (machining) efficiency is high.

The specific embodiment
The utility model is provided with cutter 12 and cover plate 13, and boring body 4 is connected on the boring machine through seam location and bolt.Main shaft 5 is assemblied in the boring body 4 with locking nut 2 through two thrust bearings 3; Clutch 1 is contained on the main shaft 5; Processed a circular groove on the external diameter of boring body 4, in support plate 6 is embedded in; Outer nut 7 is connected with support plate 6, interior silk braid 8, and depression bar 9 inserts in sliding pole axis 10 holes in the open slot with main shaft 5, and by plane bearing 3 and interior silk braid 8 encirclements, sliding pole axis 10 is packed in the endoporus of main shaft 5; Slide block box 11 is packed in the sliding window of main shaft 5, and cutter 12 is contained in the slide block box 11 and is screwed, the skewed slot coupling of the skewed slot of sliding pole axis 10 and slide block box 11.
During work, boring machine power drives main shaft 5 rotations through clutch 1, realizes rotatablely moving of cutter 12; Boring body 4 is followed the boring machine slide unit and is done and move up and down, and realizes moving up and down of cutter 12; Silk braid 8 was done and is moved up and down in rotation outer nut 7 drove, and (outer nut can not be done with respect to the boring body and move up and down, and can only rotate), interior silk braid 8 moulded rods 9, sliding pole axis 10, sliding pole axis 10 drives slide block box 11 through skewed slot and realizes 12 radial expansion.
