Description

Technical Field

[0001] The utility model relates to the field of cutting tools, in particular to a cutting tool for a CNC numerically controlled lathe. Background Art

[0002] CNC lathe tools are cutting tools used on computer numerically controlled lathes, primarily in the machining field. Through programming, they enable precise machining of internal and external cylindrical surfaces, conical surfaces, complex rotating surfaces, and threads on shafts and discs. In addition to basic turning operations, CNC lathes can also perform grooving, drilling, reaming, reaming, and boring. Their versatility meets a wide range of machining needs, from simple to complex.

[0003] Traditional CNC cutting tools, due to their fixed size and shape, cannot be folded, thus taking up a lot of space during storage and transportation. This not only increases storage costs but also limits workplace space planning. Furthermore, after use, the exposed tool head is easily damaged due to the lack of folding function, which affects subsequent processing results. Therefore, we propose a cutting tool for CNC lathes.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a tool for a CNC lathe, which has the following beneficial effects:

[0016] 1. The tool of this CNC lathe is designed to fold and store the cutter head and cutting head by rotating the adjusting arm 180 degrees on the pin and then rotating the tool rod 90 degrees so that the outer wall of the protective cover covers the adjusting arm. The foldable cutter head and cutting head can be folded up when not in use, taking up less storage space, which is especially important for machining workshops with limited space. In addition, the exposed cutting part is reduced, reducing the risk of operators being injured by accidentally touching the cutting head, thereby protecting the cutter head and cutting head and extending their service life.

[0017] 2. The tool of the CNC lathe effectively ensures that the push rod and the tool rod can drive the cutter head at the bottom of the adjusting arm to operate during the rotation process by clamping the adjusting shaft into the open groove on the adjusting arm, preventing the adjusting arm from swinging left and right in the first side opening during the rotation operation, thereby ensuring the stability of the cutting head during cutting.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 A tool for a CNC lathe includes a tool bar 1, a protective sleeve 14 being rotatably sleeved on the outer wall of the tool bar 1, a vertical push rod 2 being fixedly mounted on the top of the tool bar 1, the top of the push rod 2 extending out of the protective sleeve 14 and fixedly connected to a mounting block 4 for mounting the tool, adjustment blocks 3 being fixedly mounted on the outer walls of both sides of the push rod 2 extending out of the protective sleeve 14, a cutter head 11 being provided at the bottom of the tool bar 1, and a cutting head 12 for cutting a workpiece being fixedly mounted on the bottom of the cutter head 11, and further comprising:

[0024] The folding assembly is installed on the inner wall of the knife rod 1 and is used to fold and store the knife head 11.

[0025] The top of the shank 1 is completely in contact with the top inner wall of the protective sleeve 14 .

[0026] The top rod 2 extends out of the outer wall of the protective cover 14 and is covered with a top plate 5, and the bottom of the top plate 5 is completely in contact with the top of the protective cover 14.

[0027] There are first side openings 6 on both sides of the tool rod 1 that are interconnected, and vertical sliding grooves 7 are provided on the inner walls on both sides of the first side opening 6. An adjusting shaft 13 is slidably connected between the two sets of sliding grooves 7. When it is necessary to fold the cutter head 11 and the cutting head 12, first push the adjusting shaft 13 upward in the two sets of sliding grooves 7 to slide the adjusting shaft 13 to the uppermost position of the two sets of sliding grooves 7, so that the adjusting arm 9, the cutter head 11 and the cutting head 12 are completely inserted into the first side opening 6, and then press the outer wall of the protective cover 14 and rotate the two sets of adjusting blocks 3 so that the adjusting blocks 3 drive the top rod 2 and the bottom tool rod 1 to rotate to a ninety-degree angle, so that the outer surface of the second side opening 15 completely covers the first side opening 6, and the folding and storage is completed.

[0028] The protective cover 14 is provided with second side openings 15 that are interconnected on both sides. By clamping the adjusting shaft 13 in the opening groove 10 on the adjusting arm 9, it is effectively ensured that the push rod 2 and the cutter rod 1 can drive the cutter head 11 at the bottom of the adjusting arm 9 to operate during the rotation process, preventing the adjusting arm 9 from swinging left and right in the first side opening 6 during the rotation operation, thereby ensuring the stability of the cutting head 12 during cutting.

[0029] The folding assembly includes a pin shaft 8, an adjusting arm 9 and an open slot 10. A pin shaft 8 is fixed between the inner walls of the two sides of the knife rod 1 just below the corresponding adjusting shaft 13. The outer wall of the pin shaft 8 is rotatably sleeved with an adjusting arm 9. An open slot 10 is provided on the top of the adjusting arm 9. The adjusting shaft 13 is slidably engaged in the open slot 10, and then the adjusting arm 9 is driven by the cutter head 11 to rotate 180 degrees on the outer wall of the pin shaft 8. The adjusting shaft 13 is engaged in the open slot 10 to effectively ensure that the top rod 2 and the knife rod 1 can drive the cutter head 11 at the bottom of the adjusting arm 9 to operate during the rotation process, preventing the adjusting arm 9 from swinging left and right in the first side opening 6 during the rotation operation, thereby ensuring the stability of the cutting head 12 during cutting.

[0030] Working principle: When the cutter head 11 and the cutting head 12 need to be folded, first push the adjusting shaft 13 upward in the two sets of slide grooves 7 to make the adjusting shaft 13 slide to the uppermost position of the two sets of slide grooves 7, and then drive the adjusting arm 9 to rotate 180 degrees on the outer wall of the pin shaft 8 through the cutter head 11, so that the adjusting arm 9, the cutter head 11 and the cutting head 12 are completely entered into the first side opening 6, and then press the outer wall of the protective cover 14 and rotate the two sets of adjusting blocks 3 so that the adjusting blocks 3 drive the top rod 2 and the bottom knife rod 1 to rotate to a 90-degree angle so that the outer surface of the second side opening 15 completely covers the first side opening 6, and the folding and storage is completed. The adjusting shaft 13 is clamped in the opening groove 10, which effectively ensures that the top rod 2 and the knife rod 1 can drive the cutter head 11 at the bottom of the adjusting arm 9 to operate during the rotation process, and prevents the adjusting arm 9 from swinging left and right in the first side opening 6 during the rotation operation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
