Referring to fig. 1-4, the present invention provides an embodiment: the utility model provides a machinery burring hand tool, including wedge rectangular block 1, centering guide pin bushing 2, bolt cover 3, bolt 4, hexagon socket head cap screw 5, packing ring 6, assembled handle 7, cutter arbor 8 and box wallboard 9, settle the right-hand member side of wedge rectangular block 1 has centering guide pin bushing 2, and the upper end side of wedge rectangular block 1 installs bolt cover 3 through cup jointing, settle the left end of centering guide pin bushing 2 has bolt 4, and hexagon socket head cap screw 5 is installed to the left end of wedge rectangular block 1, packing ring 6 settles in hexagon socket head cap screw 5's the outside, and the tip of hexagon socket head cap screw 5 settles and have assembled handle 7, cutter arbor 8 is installed to the left end of wedge rectangular block 1, and box wallboard 9 is installed to the outer end side of wedge rectangular block 1.

Furthermore, the right end of the wedge-shaped long block 1 is rectangular, the diameter of the left end opening of the wedge-shaped long block 1 is smaller than that of the right end of the wedge-shaped long block 1, the wedge-shaped long block 1 and the centering guide sleeve 2 are matched and sleeved with each other, the centering guide sleeve 2 and the box body wall plate 9 are adjusted with each other, the right end of the wedge-shaped long block 1 is rectangular, the wedge-shaped long block can be conveniently taken away and used, the operation and the control are more convenient, the wedge-shaped left end of the wedge-shaped long block can be conveniently inserted into the end side of the centering guide sleeve 2 to be assembled and used, the butt joint is convenient, meanwhile, the centering guide sleeve 2 and the box body wall plate 9 are sleeved with each other, the end part;

furthermore, the bolt sleeve 3 and the cutter bar 8 are mutually sleeved, and the bolt 4 and the wedge-shaped long block 1 are mutually embedded and movably connected, so that the bolt sleeve 3 and the cutter bar 8 are mutually sleeved, the bolt can be conveniently spliced, the splicing effect of the device body in use is conveniently improved, the device body is more convenient to disassemble, and the bolt 4 is used, so that the wedge-shaped long block 1 can be more firmly positioned;

further, the socket head cap screw 5 and the cutter arbor 8 between mutually support and be connected, and mutually support between packing ring 6 and the socket head cap screw 5 and cup joint, threaded connection each other between assembled handle 7 and the socket head cap screw 5, and the horizontal axis of the two coincides each other, through the butt joint of socket head cap screw 5, can splice cutter arbor 8, accomplish its montage and use, can be through the use of assembled handle 7 simultaneously, can conveniently take away the controlling device body, the better burring operation that carries on.

The working principle is as follows: cutter arbor 8 is a cylinder and gets rid of the middle part, 8 internal walls of cutter arbor have certain gradient in a certain position department, make triangle-shaped cutting edge at cutter arbor 8 bottom, will have and put in body of rod bottom intermediate space with little wedge 1 that the inner wall gradient is the same and have the connecting rod, then it has the annular knurl to overlap from the 8 other end of cutter arbor to have centering guide pin bushing 2 outside, it puts into the position of fenestrate position and connecting rod upper end hole from this end to have the annular knurl to bolt cover 3 outside again, connect wedge and bolt cover 3 in the back with bolt 4 patchhole, need to screw up fixedly through hexagon socket head cap screw 5 with assembled handle 7 at the during operation, get rid of box inner wall burr through rotatory assembled handle 7 with the cutter. Just so assemble into a complete mechanical burring hand tool, this type of burring machine tool goes on in batches for guaranteeing the processing, will assemble in advance, at first chooses suitable centering cover, puts the centering cover to the cutter arbor 8 middle part from the cutter arbor 8 rear, later inserts bolt 4 and overlaps 3 connection wedges with the bolt, at last with assembled handle 7 dress can. The tool is mainly used for deburring processing of processing instruments of small factories, namely deburring processing is carried out on the inner sides of punching holes of boxes, pipes and flat plates or invisible places, because burrs appear on a plurality of places of processed workpieces due to a plurality of processing modes such as a boring machine, a milling machine and a drilling machine at present, such as outer wall edges and corners or inner walls of outer walls of forming holes, or burrs of hidden inner walls of boxes or through holes which cannot be removed by common deburring tools, the deburring tool of the utility model mainly removes burrs on the places,

after the deburring tool is assembled, firstly, because a wedge-shaped block is not completely clamped, the deburring tool can be placed into a hole when the bottom opening of a cutter rod 8 is small, a selected centering sleeve is placed at the position of the hole to be fixed, then the tool is placed downwards until a cutting edge completely enters the hole, the rear edge of the cutter of the tool is ensured to be below the hole wall, then a bolt sleeve 3 is upwards pulled, a long wedge-shaped block is propped open at the bottom of the cutter rod 8 through the bolt sleeve 3 until the rear edge props against the outer side of the hole, at the moment, the uppermost cutter rod 8 is rotated leftwards and rightwards to remove the inner side or invisible burrs, after the burrs are removed, the bolt sleeve 3 is pulled downwards until the cutter rod 8 recovers the small opening state, then the centering sleeve is pulled out, finally, the deburring tool is taken out, and the next;

wherein:

the wedge-shaped long block 1 is used for expanding the front end of the cutter rod 8 when the bolt sleeve 3 is pulled, so that the blade at the front end can cut burrs inside the hole. A hard iron block with better effect can be selected;

the centering guide sleeve 2 is used for fixing a deburring tool, so that the cutter bar 8 is always positioned at the center of a hole, and the operation cannot be influenced by left-right shaking during deburring. Because the workpiece is often oil stain, in order to prevent workers from pushing in or pulling out the centering guide sleeve 2 to slip during operation, knurls are engraved on the outer surface of the centering guide sleeve 2, so that the friction force is increased;

the bolt sleeve 3 is used for pushing and pulling the wedge-shaped long block 1, burrs can be cut off when the front end of the wedge-shaped long block 1 is expanded, and the diameter of the wedge-shaped long block 1 can be folded when the front end of the wedge-shaped long block is loosened, so that the tool can be put into or taken out of the hole conveniently. The outer surface of the roller is also provided with knurls, so that the friction force is increased;

a cutter bar 8: no. 45 high-quality carbon structural steel is selected, and has good plasticity, proper strength and good technological properties. The tail of the cutter rod 8 is milled into a hexagonal shape by a milling machine so as to be convenient for assembling a handle and fixing the assembled handle after the assembled handle is assembled, the cutter head part of the cutter rod 8 is a cutter edge, local quenching treatment is carried out, and the hardness of the cutter edge is improved to 45-50 HRC (Rockwell hardness). Cutting edge with 0 degree front angle and certain back angle for cutting burr on inner side of hole wall

Assembled handle 7: the circular shape handle is fixed by socket head cap screw 5, can dismantle, and it is convenient to load onto the rotation, and the material also is made by 45 # steel, and outside process annular knurl, friction dynamics is moderate. The worker can cut off burrs on the inner side of the hole wall by rotating the handle by hand.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
