[0027] The feed box 12 is transmission-connected to the spindle box 13 , and the feed box 12 is transmission-connected to the lead screw 121 .

[0028] The spindle box 13 is a power unit of the lathe body 100 . A spindle is installed in the spindle box 13 , and a chuck 131 is fixedly installed at one end of the spindle facing outward. In this embodiment, the chuck 131 is a three-jaw chuck.

[0029] The saddle 15 is slidably mounted on two guide rails 111. A slide box 151 is arranged on the saddle 15 corresponding to the lead screw 121. A transverse coarse adjustment hand wheel 1511 for driving the slide box 151 to move is installed on the outer side surface of the slide box 151. A longitudinal adjustment hand wheel 152 for driving the middle slide 16 to move is installed on one side of the saddle 15.

[0030] The middle slide plate 16 is slidably mounted on the saddle 15 in a direction perpendicular to the guide rail 111 .

[0031] A transverse fine adjustment hand wheel 181 for driving the small slide 18 to slide relative to the rotary disk 17 is installed at one end of the small slide 18 .

[0032] refer to Figure 4 As shown, the tool holder 19 includes a tool holder body 191 rotatably disposed on the small slide 18 and a handle sleeve 192 located at the center of the top of the tool holder body 191. In this embodiment, a threaded hole 1921 is provided at the top of the handle sleeve 192.

[0033] like Figure 4 As shown, the fixing mechanism 300 includes a disc body 31 , a threaded rod 32 and a pressing block 33 .

[0034] In this embodiment, the disk body 31 is a disk-shaped structure. In this embodiment, three handles 311 are fixed at equal intervals on the side of the disk body 31. The threaded rod 32 is fixedly installed at the center of the bottom of the disk body 31, and the threaded rod 32 corresponds to the threaded hole 1921 on the tool holder 19.

[0035] In this embodiment, four pressing blocks 33 are provided, but not limited to four, and the pressing blocks 33 are arranged at equal intervals at the bottom of the tray body 31 around the center of the tray body 31 .

[0036] refer to Figure 1 and 3 As shown, the cutting mechanism 200 includes a rotating shaft 21 , a spacing sleeve 22 sleeved on the rotating shaft 21 , two cutters 23 sleeved on the rotating shaft 21 and located on both sides of the spacing sleeve 22 , and a nut 24 .

[0037] One end of the rotating shaft 21 corresponds to the chuck 131 and is clamped and fixed by the chuck 131, and the other end of the rotating shaft 21 is held by the top of the tailstock 14, so that the rotating shaft 21 is clamped by the chuck 131 and the tailstock 14, so that the rotating shaft 21 can rotate with the chuck 131, and the rotating shaft 21 is also provided with an external threaded portion 211 corresponding to the nut 24.

[0038] The spacing sleeve 22 is clearance-matched with the rotating shaft 21 , so that the spacing sleeve 22 can be detachably sleeved on the rotating shaft 21 , and the length of the spacing sleeve 22 can be replaced according to actual needs.

[0039] In this embodiment, the cutter 23 is a saw blade.

[0040] Two nuts 24 are provided, which are screwed onto the external threaded portion 211 of the rotating shaft 21 , and the two nuts 24 respectively abut against the side surfaces of the two cutters 23 facing away from the spacing sleeve 22 .

[0041] The working process of the modified lathe for processing and forming square parts of the present invention is described below in conjunction with the accompanying drawings:

[0042] The blank cut from the rod is sent to the drilling machine and the center hole is drilled to obtain the workpiece to be processed; first, a spacing sleeve 22 of appropriate length is selected according to actual needs, and the center hole of the workpiece to be processed is passed through the handle sleeve 192 on the tool holder 19, and then the operator holds the handle to align the threaded rod 32 on the disk body 31 with the threaded hole 1921 and screws it in, and finally the clamping block 33 at the bottom of the disk body 31 is pressed against the top of the workpiece, thereby fixing the workpiece on the tool holder 19, completing the loading process before processing.

[0043] Then, the lathe body 100 is turned on to rotate the rotating shaft 21, and the rotation speed of the chuck 131, i.e., the rotating shaft 21, is adjusted to a suitable value by controlling the spindle box 13, and the slide box 151 is driven to slide along the lead screw 121 by the transverse coarse adjustment handwheel 1511, thereby driving the saddle 15 and the workpiece on the saddle 15 to move along the guide rail 111 until the workpiece moves to the exact center position of the two tools 23, and further driving the small slide 18 to move by the transverse fine adjustment handwheel 181, so as to make precise adjustment to the position of the workpiece on the tool holder 19, and finally, by rotating the longitudinal coarse adjustment handwheel 1511, the middle slide 16 is driven to move in a direction perpendicular to the guide rail 111, that is, the workpiece is driven to move closer to the tool 23, until the tool 23 passes through the workpiece to cut the opposite side of the workpiece, so that the edge of the workpiece cut by the tool 23 forms a parallel plane. ; After the workpiece passes through the tool 23 and completes one side cutting, the rotation of the chuck 131 is turned off, and then the disk body 31 is rotated by the handle 311, thereby driving the tool holder body 191 and the workpiece on the tool holder body 191 to rotate 90°, and the chuck 131 is reversed by adjusting the spindle box 13, and the workpiece is driven to pass through the tool 23 again by the longitudinal adjustment hand wheel 152, and the workpiece is cut against the side again by the tool 23 to form two parallel planes again. After two perpendicular cuts are made on the side of the workpiece, the workpiece is processed into a square piece. If the required square piece is of unequal length and width, the spacing sleeve 22 can be replaced to change the spacing between the two tools 23. In order to improve the processing efficiency, the workpiece to be processed can also be processed alternately by two lathes modified in this embodiment with different spacing sleeves 22.

[0044] The present invention discloses a modified lathe for processing and forming square parts. The modified lathe is modified based on an existing lathe main body 100, and comprises a lathe main body 100 and a cutting mechanism 200 and a fixing mechanism 300 arranged on the lathe main body 100. The cutting mechanism 200 comprises a rotating shaft 21 clamped on a chuck 131 of the lathe main body 100 and two cutting tools 23 spaced apart and sleeved on the rotating shaft 21. The fixing mechanism 300 comprises a disc body 31 rotatably connected to a tool holder 19 of the lathe main body and a pressing block 33 arranged on the disc body. The pressing block 33 on the disc body 31 can clamp and fix the workpiece on the tool holder 19, and the lathe main body 100 drives the tool holder 19 and the workpiece to move toward the cutting tool 23, so as to cut the opposite sides of the workpiece to form parallel planes. The rotating tool holder 19 drives the workpiece to rotate 90° and then cuts the opposite sides of the workpiece again. Finally, the workpiece is quickly processed into a square part through two perpendicular cuts. The modified lathe for processing and forming square parts reduces the processing cost and is easy to implement.

[0045] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the scope of the present invention through the above description. The technical scope of this invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
