Description

Drilling deburring tool

Technical Field

The utility model relates to a burring frock technical field especially relates to a drilling burring frock.

Background

When drilling holes in the side wall of a workpiece with an inner hole, the inner hole of the workpiece can turn up burrs. The existing treatment method is to adopt manual removal or other tools for removal, so that a procedure is added, the labor cost is increased, and the labor intensity is high.

SUMMERY OF THE UTILITY MODEL

Handle the problem that the hole burr increases cost of labor and intensity of labour among the prior art scheme, the utility model provides a drilling burring frock.

The utility model provides a following technical scheme: the utility model provides a drilling burring frock, is including cup jointing the dabber on the work piece hole, the dabber lateral wall is provided with at least one mounting groove, be provided with the shearing piece in the mounting groove, the outer wall of shearing piece just is provided with toper shear groove with work piece hole clearance fit, the less one end orientation of toper shear groove area the dabber outside makes the outer wall of shearing piece with toper shear groove handing-over department forms the shearing edge of a knife.

Preferably, the toper shear groove is logical groove, just the bottom of mounting groove is provided with the burr holding tank.

Preferably, the quantity of mounting groove is a plurality of and centers on dabber axis evenly distributed, and is a plurality of burr holding tank communicates each other.

Preferably, the dabber is provided with the reference column, the reference column is kept away from the one end of dabber is provided with the external screw thread.

Preferably, the material of the shearing part is hard alloy.

The utility model has the advantages that: before drilling, the conical shearing groove of the shearing piece is aligned to the drill bit, burrs generated by drilling are turned inwards in the conical shearing groove, the workpiece is rotated relative to the mandrel, the burrs are cut off by utilizing the shearing force of the shearing tool opening acting on the burrs, simplicity and convenience are realized, and the labor cost generated by manually removing the burrs is saved.

Detailed Description

The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides a drilling burring frock as shown in fig. 1-3, including cup jointing dabber 1 on 8 holes of work piece, 1 lateral wall of dabber is provided with at least one mounting groove 2, be provided with shearing piece 3 in the mounting groove 2, shearing piece 3's outer wall and 8 hole clearance fit of work piece just are provided with toper shear groove 4, the less one end orientation of 4 area in toper shear groove 1 outside messenger the outer wall of shearing piece 3 with 4 handing-over departments in toper shear groove form the shearing edge of a knife 5.

The core shaft is sleeved on the inner hole of the workpiece and used for positioning the workpiece, so that the clamping is convenient. The shearing part is used for removing burrs by utilizing the shearing force generated when the workpiece rotates relative to the shearing part, can be made of hard alloy, is higher in cost and can generate abrasion, and the shearing part is arranged in the mounting groove on the surface of the side wall of the mandrel, so that the shearing part is convenient to replace. Specifically, the shearing part is provided with a conical shearing groove, and one end with a smaller area faces the outer side of the shearing part to form a sharp shearing knife edge, so that burrs are cut conveniently; meanwhile, the outer wall of the shearing part is in clearance fit with the inner hole of the workpiece, so that the shearing tool opening can be tightly attached to the inner hole of the workpiece, and the remaining amount of burrs is reduced as much as possible.

The utility model discloses when using, can at first aim at the drill bit of drilling with shearing the piece, make the burr enstrophe that drilling produced in the toper shearing groove, rotatory for the dabber with the work piece, utilize the shearing force of shearing the tool opening effect on the burr to amputate the burr, simple and convenient.

Preferably, the tapered shearing groove 4 is a through groove, and the bottom of the mounting groove 2 is provided with a burr receiving groove 6. The burr that is cuted falls into the burr holding tank through the toper shear groove, and the burr holding tank can be kept in by the burr of cuting, makes the drilling operation can continue to go on, avoids increasing the time of trading and produces.

Preferably, the quantity of mounting groove 2 is a plurality of and centers on 1 axis evenly distributed of dabber, it is a plurality of burr holding tank 6 communicates each other, is convenient for clear up the burr that accumulates.

Preferably, the mandrel 1 is provided with a positioning column 7, and one end of the positioning column 7, which is far away from the mandrel 1, is provided with an external thread. As shown in fig. 1, the mandrel is fixed on the support frame 9 through a positioning column, and an external thread on the positioning column is used for matching with a bolt to fix the mandrel.

Preferably, the material of the shearing part 3 is cemented carbide.

The foregoing is directed to one or more embodiments of the present invention, which are described in some detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
