Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1-7, a burr cleaning tool after a workpiece is machined is disclosed, in which the burr cleaning tool 1 includes a shank 11, and a cleaning tool 12 is inserted into one end of the shank. As shown in FIG. 6, the cleaning tool 12 is driven to move along the length of the side edge by holding the tool holder 11 and contacting the cleaning tool 12 with the side edge of the workpiece where the machined burr is formed, so as to rapidly clean the machined burr and improve the surface smoothness of a housekeeper.

In order to increase the flexibility of the operation of the deburring tool, which is usually formed by machining in various forms and has a complicated internal structure, a rotating mechanism for rotating the deburring tool 12 relative to the arbor 11 is further provided at an end portion thereof, as shown in fig. 1. During operation, the knife handle 11 is obliquely placed at the position of a tiger's mouth of a right hand to be supported, a thumb, an index finger and a middle finger of the right hand are held on the rotating mechanism, and the cleaning tool 12 is driven to rotate by a corresponding angle through the driving rotation of the fingers on the rotating mechanism so as to be matched with the burr cleaning requirements of different side structures of a workpiece, improve the use flexibility of the burr cleaning tool and improve the cleaning effect of the burr cleaning tool on the workpiece.

Specifically, as shown in fig. 2, the cleaning tool 12 includes a shank portion 12a, a blade portion 12b, and a grinding portion 12c in this order. Wherein shank portion 12a is used for being connected with rotary mechanism, and blade portion 12b then moves along the contact of work piece side, clears away the processing burr, and grinding portion 12c then is used for blade portion 12b to remove to the work piece and scrapes and realize effectual clearance operation under the clearance operation to further improve this burr clearance cutter's general use nature, make it all can realize effectual burr clearance operation to the work piece of isostructure.

Specifically, as shown in fig. 1 and 6, the rotating mechanism is a rotating column 13 rotatably disposed at an end portion of the tool shank 11, and the tool shank portion 12a of the cleaning tool 12 is fixedly inserted into the rotating column 13. During operation, the right thumb, the index finger and the middle finger can be held on the rotary column 13, when the cleaning angle of the cleaning tool 12 needs to be adjusted, the inclined support of the tool holder 11 on the right tiger's mouth can drive the rotary column 13 to rotate through the fingers, the cleaning tool 12 is driven to rotate, and the cleaning angle adaptive to the workpiece structure is adjusted.

Because the burr and the workpiece body are integrated, the burr is formed by cutting the cutter during processing, and for the metal workpiece, the burr can be removed smoothly only by applying certain external force to the cleaning cutter 12, so that the cleaning angle of the cleaning tool 12 is changed by the sliding rotation of the rotary cylinder 13 compared to the right finger when the cleaning external force is applied, further, since the cleaning state of the cleaning tool 12 cannot be stabilized, as shown in FIGS. 1 and 5, the outer peripheral surface of the rotary post 13 has a polygonal structure, preferably an octagonal structure, which can make the thumb, index finger and middle finger of the right hand hold on the corresponding side surface, limit the problem of the rotation and sliding of the rotary column 13 and the cleaning cutter 12, keep the stability of the cleaning state of the cleaning cutter 12, meanwhile, the rotating column 13 can be driven to rotate quickly, and the cleaning angle of the cleaning tool 12 can be adjusted flexibly.

Specifically, as shown in fig. 2-3, the cross section of the blade portion 12b is a triangle-like structure, which can effectively scrape the burr off the workpiece after contacting the burr. The length direction of the knife edge part 12b is set to be an arc-like line structure, the structure can enable the knife edge part 12b to be relatively limited with the side edge of the workpiece (as shown in the state of figure 6), the problem that the whole cleaning tool 12 is separated from the workpiece due to the fact that the knife edge part 12b is relatively inclined with the workpiece in the forced moving process is avoided, and the cleaning stability is guaranteed.

Specifically, as shown in fig. 1 and 4, the grinding portion 12c has a plate-like structure provided at the tip of the blade portion 12b, and both side walls of the grinding portion 12c are provided as grinding rough surfaces. Because the blade part 12b is in one-way contact sliding to realize cleaning action after contacting with the side edge of the workpiece (as shown in fig. 6), when the cleaning tool 12 cleans the workpiece with the inner side edge, the side edge has a connecting corner (shown as a in fig. 7), when the blade part 12b cleans the connecting corner from one side, the un-cleaned burr is extruded in the connecting corner, so that the burr accumulated in the connecting corner can not be completely and effectively cleaned through the blade part 12b, therefore, the blade part 12b extending into the connecting corner through the plate-shaped structure can repeatedly grind and clean the accumulated burr through the grinding rough surface of the burr, further, the blade part 12b can be assisted to completely and effectively clean the burrs processed by different workpiece structures, and the problem that the burr is difficult to clean and causes residue is solved.

The principle of the utility model is that: when the burrs on the side edge of the machined workpiece are cleaned, the tool shank 11 is obliquely placed at the jaw of the right hand to be supported, the thumb, the index finger and the middle finger of the right hand are held on the rotating column 13, the blade part 12b of the cleaning tool 12 is contacted with the side edge of the workpiece, external force is applied to the whole cleaning tool to enable the blade part 12b to move along the side edge of the workpiece, and then the burrs on the side edge are scraped and treated. When the cleaning angle of the cleaning tool 12 needs to be adjusted, the tool shank 11 is supported on the jaw of the right hand in an inclined mode, the rotating column 13 can be driven to rotate through fingers, the cleaning tool 12 is driven to rotate, and then the cleaning angle matched with a workpiece structure is adjusted. When the burrs at the corners connected with the side edges of the workpiece are cleaned, the grinding rough surface at the outer end part of the cleaning tool 12 moves in a reciprocating contact manner to grind and clean the accumulated burrs at the corners, so that the cleaning tool can completely, effectively and quickly clean the processing burrs of different workpiece structures, and the problem that the burrs are difficult to clean and cause residue is solved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
