The tightening saw pin is installed on the upper mounting part by tightening a nut.

[0005] The saw blade turning and cutting auxiliary tool mentioned above includes a first cylinder and a baffle fixed to the bottom of the first cylinder. The upper end face of the first cylinder has an axially opened first mounting groove. Two first mounting holes for the first through pin to pass through are symmetrically arranged on the two sides of the first mounting groove. The first cylinder is inserted from bottom to top into the lower mounting part and is limited by the baffle. The lower end of the saw blade extends into the first mounting groove and is connected to the first cylinder through the first through pin.

[0006] The saw blade turning and cutting auxiliary tool described above has a tightening saw pin, which is a stepped column structure with a smaller upper part and a larger lower part. The upper part of the tightening saw pin has an external thread in the circumference, and the bottom of the tightening saw pin has a second mounting groove in the axial direction. Two second mounting holes are symmetrically arranged on the two sides of the groove wall for the second through pin to pass through. The upper end of the saw blade extends into the second mounting groove and is fixedly connected to the tightening saw pin through the second through pin. The tightening saw pin passes through the upper mounting part from bottom to top and is locked by tightening the nut.

[0007] The saw blade turning and cutting tool mentioned above includes a tightening nut comprising a nut body, an internal thread in the central hole of the nut body, and two shanks symmetrically arranged circumferentially on the nut body.

[0008] The saw blade turning and cutting auxiliary tool described above has its tool holder mounted on the tool holder of the turning equipment.

[0009] The beneficial effects of this utility model are as follows: This utility model utilizes ordinary saw blades to meet the sawing capability of ferrous metals, and through the positioning and fixing of saw blade turning and cutting auxiliary tools and the radial feed function of lathe follow tool holder, it meets the saw blade sawing and continuous feeding until the blank is cut off.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 2 , Figure 3 As shown, a saw blade turning and cutting auxiliary tool includes a saw blade 1 and a tool holder 2. The tool holder 2 includes a frame 3. The front end of the frame 3 extends upward and downward to the upper and lower sides respectively to form an upper mounting part 4 and a lower mounting part 5. The saw blade 1 is vertically arranged. The lower end of the saw blade 1 is connected to a pull saw pin 7 through a first through-hole pin 6. The pull saw pin 7 is installed on the lower mounting part 5. The upper end of the saw blade 1 is connected to a tightening saw pin 9 through a second through-hole pin 8. The tightening saw pin 9 is installed on the upper mounting part 4 by tightening a nut 10.

[0019] like Figure 4 As shown, the saw pin 7 includes a first cylinder 11 and a baffle 12 fixed to the bottom of the first cylinder 11. The upper end face of the first cylinder 11 has an axially formed first mounting groove 13. Two first mounting holes 14 for the first through pin 6 to pass through are symmetrically arranged on the two sides of the first mounting groove 13. The first cylinder 11 is inserted into the lower mounting part 5 from bottom to top and is limited by the baffle 12. The lower end of the saw blade 1 extends into the first mounting groove 13 and is connected to the first cylinder 11 through the first through pin 6.

[0020] like Figure 5As shown, the clamping saw pin 9 is a stepped column structure with a smaller upper part and a larger lower part. The upper part of the clamping saw pin 9 is provided with external threads in the circumferential direction. The bottom of the clamping saw pin 9 has a second mounting groove 15 axially opened. Two second mounting holes 16 are symmetrically arranged on the two sides of the groove wall for the second through pin 8 to pass through. The upper end of the saw blade 1 extends into the second mounting groove 15 and is fixedly connected to the clamping saw pin 9 through the second through pin 8. The clamping saw pin 9 is inserted from bottom to top on the upper mounting part 4 and locked by tightening nut 10.

[0021] like Figure 6 As shown, the tightening nut 10 includes a nut body 17, with an internal thread in the center hole of the nut body 17, and two shanks 18 symmetrically arranged around the nut body 17. The shanks 18 are used to tighten the nut 10 with less effort.

[0022] When installing and using this auxiliary tool, after fixing the saw blade 1 to the saw pin 7 and the tightening pin 9 by the first through pin 6 and the second through pin 8, tighten the tightening nut 10 to tighten the saw blade 1. Then install the tool holder 2 on the tool holder of the turning equipment, adjust the cutting position of the saw blade 1, and then you can process the product. Figure 7 As shown; precautions should be taken when using: the hardness of the workpiece should not exceed 40 HRC; saw blade 1 needs to be quenched; the feed speed should not exceed 2 mm / min; when the cutting color turns bluish-black, the saw blade cutting position should be changed or a new saw blade should be replaced. Because sawing involves multiple small saw teeth cutting simultaneously, the chips are small and easy to remove, so the blade is not prone to breakage.
