[0032] The overall structure, working principle and technical effects of the chip cutting tool provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.
[0033] Please refer to Figures 1 to 3The chip cutting tool 100 provided by the present invention is used for tapping a hole in a workpiece to form a threaded hole.
[0034] The chip jig 100 includes a chip body 110, a first blade 120, and a second blade 140. A chip removal channel 130 is provided on the chip body 110. The first blade 120 is provided on the chip body 110; the first blade 120 and the chip removal channel 130 are spaced apart. The second blade 140 is provided in the chip removal channel 130. The second blade 140 helps to stir and cut the chip debris, facilitating the smooth discharge of the debris and preventing clogging of the chip removal channel 130. It also reduces the amount of debris in the tapped hole of the workpiece and in the chip removal channel 130, reducing the risk of wear and breakage of the chip jig 100 and extending the service life of the chip jig 100.
[0035] It is understood that the first blade 120 is used to form threads in the tapped hole of the workpiece. The shape and size of the first blade 120 can be designed according to the parameters of the thread to be formed.
[0036] Optionally, the radial height of the second cutting edge 140 along the chip body 110 is no greater than the depth of the chip removal channel 130. In other words, the end of the second cutting edge 140 away from the bottom wall of the chip removal channel 130 should be no higher than the outer peripheral surface of the chip body 110. This arrangement ensures that when the first cutting edge 120 is tapping the tapped hole, the second cutting edge 140 does not affect the operating accuracy of the first cutting edge 120, that is, it does not interfere with the formation of threads in the tapped hole, thereby improving tapping efficiency and accuracy.
[0037] Optionally, the first blades 120 include multiple groups, and the multiple groups of first blades 120 are evenly spaced along the circumference of the chip body 110, and each group of first blades 120 includes multiple first cutting portions 121. In this embodiment, the first blades 120 include four groups, and the four groups of first blades 120 are evenly spaced in the circumferential direction. In this way, the first blades 120 of each group are evenly stressed, reducing wear, which is beneficial to increasing the service life of the first blades 120, and is beneficial to improving work efficiency and work accuracy. Of course, in some embodiments, the first blades 120 may also include one group, two groups, three groups, five groups, six groups or more, which are not specifically limited here.
[0038] Optionally, the plurality of first blades 120 are threaded and used to form threaded holes in a workpiece. The axial spacing of the plurality of first cutting portions 121 can be designed according to the pitch of the threads to be formed.
[0039] Optionally, the second blades 140 include two groups, and the two groups of second blades 140 are symmetrically arranged about the axis of the chip body 110. The second blades 140 and the first blades 120 are spaced apart in the circumferential direction of the chip body 110. The second blades 140 can rotate with the chip body 110 to agitate chips that fall into the chip discharge channel 130, preventing the chips from clogging the chip discharge channel 130. The second blades 140 can also cut off chips that fall into the chip discharge channel 130, further preventing chip clogging and facilitating chip discharge.
[0040] In this embodiment, two groups of second blades 140 are provided. In other embodiments, one, three, four or more groups of second blades 140 may be provided, which is not specifically limited here.
[0041] Optionally, a through hole 142 is provided on the second blade 140. The design of the through hole 142 facilitates the discharge of debris and prevents debris blockage. The shape, size and number of the through hole 142 are not limited.
[0042] Optionally, each set of second blades 140 includes a plurality of second cutting portions 141, which are arranged in the chip discharge channel 130 along the axial direction of the chip body 110. Each second cutting portion 141 is provided with a through hole 142, and the axis of the through hole 142 is parallel to the axis of the chip body 110. In this arrangement, the second cutting portions 141 are arranged along the axial direction, and each second cutting portion 141 has a through hole 142, which facilitates the timely discharge of debris.
[0043] Optionally, the number of first blades 120 is greater than the number of second blades 140. In this embodiment, the number of first cutting portions 121 exceeds the number of second cutting portions 141. In other words, the axial spacing between two adjacent second cutting portions 141 is larger than the axial spacing between the first cutting portions 121. The second cutting portions 141 only need to perform the functions of disturbing and cutting off the debris, and their number can be relatively small. This can occupy less space in the chip removal channel 130, provide more space for the debris in the chip removal channel 130, facilitate the discharge of the debris, and prevent the debris from clogging the chip removal channel 130.
[0044] Optionally, the chip body 110 is cylindrical. In other embodiments, the chip body 110 may also adopt other shapes, which are not specifically limited here. It should be understood that the length of the chip body 110 is greater than the length of the chip discharge channel 130. This helps to improve the structural strength of the chip body 110. The axial length of the first blade 120 is less than the length of the chip discharge channel 130. In addition, the first blade 120 is provided from the end of the chip body 110 where the chip discharge channel 130 is provided, thereby improving the structural strength of the chip body 110.
[0045] It should be understood that the first blade 120 and the second blade 140 can be integrally formed with the chip body 110, or can be separately connected or welded to the chip body 110, etc., which is not specifically limited here.
[0046] Optionally, the chip body 110 is provided with a mounting portion 150, which is used to securely connect the chip body 110 to a driver. In this embodiment, the end of the chip body 110 away from the first cutting edge 120 serves as the mounting portion 150, allowing the chip body 110 to be mounted to the driver. In this embodiment, the mounting portion 150 has a quadrilateral cross-section and can be plugged into the driver to prevent rotation.
[0047] It can be understood that since the length of the chip body 110 is greater than that of the first blade 120, a blank column 111 is left between the first blade 120 and the mounting portion 150, which can improve the structural strength of the chip body 110 and the force-bearing performance of the tail.
[0048] The present invention also provides a chip cutting device, comprising a driving member and a chip cutting jig 100 as described in any of the aforementioned embodiments, wherein the driving member and the chip cutting jig 100 are connected. The driving member and the mounting portion 150 on the chip cutting body 110 are fixedly connected, including but not limited to plugging, clamping, welding, bolting, or other connection methods.
[0049] The chip cutting tool 100 and chip cutting device provided in the embodiment of the present invention work as follows:
[0050] The driving member is connected to the mounting portion 150. One end of the chip body 110 having the first blade 120 is aligned with the tapped hole on the workpiece. The driving member can drive the chip body 110 to rotate so that the first blade 120 forms a thread in the tapped hole of the workpiece, and when the first blade 120 is working, the second blade 140 can achieve agitated cutting of the chips that fall into the chip discharge channel 130, preventing the chips from clogging the chip discharge channel 130 and facilitating the smooth discharge of the chips. In this way, the wear of the first blade 120 by the chips can be reduced, and the risk of wear and breakage of other tapping jigs by the chips during subsequent tapping can also be reduced.
[0051] In summary, the chip cutting tool 100 and the chip cutting device provided by the embodiment of the present invention have the following beneficial effects, including:
[0052] The chip jig 100 provided in the embodiment of the present invention has a second blade 140 disposed within the chip removal channel 130. The second blade 140 helps to stir and cut the chips, facilitating the smooth discharge of the chips and preventing blockage in the chip removal channel 130. This also reduces the amount of chips in the tapped hole of the workpiece and in the chip removal channel 130, lowering the risk of wear and breakage of the chip jig 100 and extending the service life of the chip jig 100.
[0053] The chip cutting device provided by the embodiment of the present invention includes a driving member and the above-mentioned chip cutting fixture 100. The driving member can drive the chip cutting fixture 100 to rotate, thereby improving the tapping efficiency. The chip cutting device has high working efficiency, is not easy to clog the chip removal channel 130, and has a long service life.
[0054] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
