Abstract
The invention provides a device for grinding the inner wall of a hole. The device comprises at least three round cutting discs, gaskets, a pneumatic rod, a pneumatic device and a pneumatic device output shaft. The pneumatic device is installed on the pneumatic rod, the pneumatic device output shaft is connected with the at least three round cutting discs, and one gasket is arranged between every two round cutting discs. Multiple notches are distributed in the edge of each round cutting disc, and the thickness of the gaskets is smaller than or equal to that of the round cutting discs. The grinding speed is increased, one gasket is arranged between every two round cutting discs to separate the round cutting discs, and gaps can be formed between the round cutting discs. Slightly-protruding burrs and unsmooth positions can be ground through the edges of the gaps when the handheld pneumatic rod is fed into the hole, and parts of defects of the inner wall of the deep hole can be removed in the rotating process; and the round diamond cutting discs are more durable, and deep hole processing is facilitated.
Description
Technical field
The present invention relates to casting grinding device field, be specifically related to a kind of hole inner wall grinding device.
Background technology
In casting grinding process, there is the situation that hole inwall needs polishing, multiplex air grinder sanding and polishing endoporus in existing operation, it works in the pivotal mode of pneumatic motor drives emery wheel, utilizes the grinding face of emery wheel to carry out grinding.When utilizing air sander polishing hole inwall, often cannot be polished to projection and the burr of hole inwall, sanding and polishing poor effect.When running into the comparatively dark and hole that aperture is less, existing milling tools is difficult to meet the demands.
Summary of the invention
In view of the defect that prior art exists, the invention provides a kind of hole inner wall grinding device, it is convenient to deep hole processing and can reduces the burr of inner walls of deep holes, improves crudy.
In order to achieve the above object, the technical solution adopted in the present invention is a kind of hole inner wall grinding device, and it comprises at least three circular cutting blades, pad, air-leg, pneumatic means, pneumatic means output shaft; Air-leg installs pneumatic means, and pneumatic means output shaft connects at least three circular cutting blades, arranges pad between every two circular cutting blades; The thickness of described pad is less than or equal to the thickness of circular cutting blade; Described circular cutting blade is waste and old circular cutting piece made from diamond; Described circular cutting blade arranges five; The some breach of described circular cutting blade edge distribution; Described breach is uniformly distributed at circular cutting blade edge.
Beneficial effect of the present invention:
Original grinder buffing changes into and utilizes multiple circular cutting blade to complete sanding and polishing by the present invention, polishing speed is accelerated, and arrange pad between every two circular cutting blades to be separated, the gap that there is 5 ~ 8mm therebetween can be made, the edge in these gaps polishing burr outstanding a little and out-of-flatness can be utilized when hand-held pneumatic bar feeds in hole; Evenly arrange breach at the periphery of circular cutting blade, also can remove the part flaw of inner walls of deep holes in its rotary course, circular cutting piece made from diamond is more durable, and general air-leg adds and grows to 2m by technical scheme of the present invention, is convenient to deep hole processing.

Detailed description of the invention
A kind of hole inner wall grinding device, it comprises at least three circular cutting blades 1, pad 4, air-leg 5, pneumatic means 7, pneumatic means output shafts 6; Air-leg 5 is installed pneumatic means 7, pneumatic means output shaft 6 connects five three circular cutting blades 1, arranges pad 4 between every two circular cutting blades 1; Described circular cutting blade 1 is fixed by bolt 2 and pneumatic means output shaft 6, and the thickness of described pad 4 is less than or equal to the thickness of circular cutting blade 1, and described circular cutting blade 1 is waste and old circular cutting piece made from diamond; Described circular cutting blade 1 edge is uniformly distributed three breach 2.
The course of work: hand-held pneumatic bar 5, pneumatic means 7 drives the some circular cutting blade 1 be connected on pneumatic means output shaft 6 to rotate, and some circular cutting blade side a form an apertured working face of band, and these working faces can be polished to hole inwall 8; Hand-held pneumatic bar 5 feeds in process in hole, and these circular cutting blade edge b can polish through row to the projection of hole inwall 8 and burr; In rotary course, around some circular cutting blades 1, equally distributed gap edge c also can polish through row to the projection of hole inwall 8 and burr.
Original grinder buffing changes into and utilizes multiple circular cutting blade to complete sanding and polishing by the present invention, polishing speed is accelerated, and arrange pad between every two circular cutting blades to be separated, the gap that there is 5 ~ 8mm therebetween can be made, the edge in these gaps polishing burr outstanding a little and out-of-flatness can be utilized when hand-held pneumatic bar feeds in hole; Evenly arrange breach at the periphery of circular cutting blade, also can remove the part flaw of inner walls of deep holes in its rotary course, circular cutting piece made from diamond is more durable, and general air-leg adds and grows to 2m by technical scheme of the present invention, is convenient to deep hole processing.
