[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] However, there are still some problems in the actual use of the existing CNC lathe clamping device: First, the existing CNC lathe clamping device usually clamps the required parts through two clamping blocks. When encountering special-shaped parts, the clamping blocks themselves cannot clamp the special-shaped parts reasonably, which may cause the special-shaped parts to be offset during processing, thereby affecting the processing accuracy, affecting the use of the processed parts, and causing unqualified products. Utility Model Content

[0004] The purpose of the present invention is to provide a CNC machine tool for parts processing, which can fix the special-shaped parts by adapting to the special-shaped parts, and the clamping method is simple and does not require precise placement of the special-shaped parts, thereby solving the problems raised in the above-mentioned background technology.

[0008] Preferably, a second mounting plate is fixedly connected to the upper side of the other end of the fixed base, a second motor is fixedly connected to one side of the top of the second mounting plate, a second reciprocating screw is fixedly connected to the output end of the second motor, and a limiting semicircular plate is fixedly connected to one end of the second reciprocating screw away from the first motor, an M-shaped push plate is provided on one side of the limiting semicircular plate, a push plate is fixedly connected to one side of the M-shaped push plate, an internal thread is provided inside the push plate, and the push plate is threadedly connected to the second reciprocating screw through the internal thread, the push plate and the M-shaped push plate are in contact with the surface of the first mounting block, and the M-shaped push plate cooperates with the special-shaped part.

[0009] Preferably, a machine tool turning tool is fixedly connected to the interior of the CNC machine tool body, and the machine tool turning tool is arranged corresponding to the special-shaped parts.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1.

[0019] The following will be combined with the drawings in the practical embodiment to clearly and completely describe the technical solution in the practical embodiment. Obviously, the described embodiment is only a part of the embodiment of the practical embodiment, not all of the embodiments. Based on the embodiment in the practical embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical embodiment.

[0020] like Figures 1 to 5 As shown, the practical embodiment provides a CNC machine tool for parts processing, including a CNC machine tool body 1, a fixed pedestal 20 is fixedly connected inside the CNC machine tool body 1, a first mounting block 2 is fixedly connected to the upper side of one end of the fixed pedestal 20, a limiting block 3 is fixedly connected to the top of the first mounting block 2, a first motor 4 is fixedly connected to the top of the first mounting block 2 on one side of the limiting block 3, a rotating shaft 5 is fixedly connected to the output end of the first motor 4, a first bevel gear 6 is fixedly connected to the end of the rotating shaft 5 away from the first motor 4, a second bevel gear 7 is meshedly connected to the upper end of the first bevel gear 6, a first reciprocating screw 8 is fixedly connected to the inside of the second bevel gear 7, a first moving block 9 is threadedly connected to the outer side of the first reciprocating screw 8, a clamping plate 10 is fixedly connected to the outer side of the first moving block 9, and a first reciprocating screw 8 is fixedly connected to the outer side of the first moving block 9. The first motor 4 is driven, and the output end of the first motor 4 rotates to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the first bevel gear 6 to rotate. The rotation of the first bevel gear 6 drives the second bevel gear 7 meshing with it to rotate. The rotation of the second bevel gear 7 drives the first reciprocating screw 8 to rotate inside the limit block 3. The rotation of the limit block 3 drives the first moving block 9 to move. The movement of the first moving block 9 drives the clamping plate 10 to move. The clamping plate 10 moves to match the contour of the special-shaped part 19 to clamp the special-shaped part 19. Since the clamping plate 10 is designed to match the shape of the special-shaped part 19, it can perfectly match the special-shaped part 19 when clamping the special-shaped part 19, thereby perfectly adapting to the special-shaped part, preventing deviation during processing of the special-shaped part, affecting the processing accuracy, affecting the practicality of the subsequent processed parts, and causing the product to be unqualified.

[0021] Among them, a moving groove 11 is opened on one side of the limit block 3, and the moving groove 11 is adapted to the movement trajectory of the first moving block 9. The first reciprocating screw rod 8 is rotatably connected to the inside of the limit block 3. When the first reciprocating screw rod 8 is rotatably connected inside the limit block 3, because the first reciprocating screw rod 8 is not provided with a reciprocating thread at the second bevel gear 7, the first reciprocating screw rod 8 will not drive the second bevel gear 7 to rotate when it rotates, so that the first motor 4 can continuously drive the second bevel gear 7 to rotate to realize the continuous rotation of the first reciprocating screw rod 8, thereby realizing the The reciprocating motion of the first movable block 9 without the motor 4 reversing realizes the loosening and clamping of the special-shaped part 19 by the clamping plate 10, which reduces the economic consumption to a certain extent in the selection of the motor, and the movable groove 11 is adapted to the motion trajectory of the first movable block 9, so that the first movable block 9 can be limited during the movement, so as to better cooperate with the special-shaped part 19, thereby improving the clamping degree of the special-shaped part 19 and the stability of the special-shaped part 19 after clamping, and no vibration will be generated during the processing, thereby affecting the processing.

[0022] Among them, a limiting plate 22 is fixedly connected to one side of the middle of the fixed base 20 at the top of the first mounting block 2, and a special-shaped part 19 is placed on one side of the limiting plate 22, and the limiting plate 22 cooperates with the special-shaped part 19. By setting the limiting plate 22, when the special-shaped part 19 needs to be processed, it is only necessary to place the special-shaped part 19 on the first mounting block 2 and the second motor 13. Since the limiting plate 22 cooperates with the special-shaped part 19, the special-shaped part 19 will be automatically pushed in the subsequent clamping process, so that the special-shaped part 19 will automatically cooperate with the limiting plate 22 in the clamping process, which reduces the working steps of workers when processing the special-shaped part 19, improves work efficiency, and avoids the situation where the clamping position is offset due to the placement position during processing, resulting in substandard part processing.

[0023] Among them, the second mounting plate 12 is fixedly connected to the upper side of the other end of the fixed base 20, and the second motor 13 is fixedly connected to the top side of the second mounting plate 12. The second reciprocating screw rod 14 is fixedly connected to the output end of the second motor 13. The second reciprocating screw rod 14 is fixedly connected to a limited position semicircular plate 18 at one end away from the first motor 4. An M-shaped push plate 17 is provided on one side of the limited position semicircular plate 18. A push plate 16 is fixedly connected to one side of the M-shaped push plate 17. An internal thread 15 is provided inside the push plate 16. The push plate 16 is threadedly connected to the second reciprocating screw rod 14 through the internal thread 15. The push plate 16 and the M-shaped push plate 17 are in contact with the surface of the first mounting block 2. The M-shaped push plate 17 cooperates with the special-shaped part 19. By starting the second motor 13, the output end of the second motor 13 rotates The push plate 16 is driven to move by the internal thread 15. Since the push plate 16 and the M-shaped push plate 17 are in contact with the surface of the first mounting block 2, the surface of the first mounting block 2 limits it and does not rotate synchronously with the second motor 13, so that the push plate 16 moves to push the M-shaped push plate 17 to move. The M-shaped push plate 17 moves to cooperate with the special-shaped part 19. After being pushed to a certain distance, the two sides of the special-shaped part 19 are clamped by the M-shaped push plate 17 and the limiting plate 22 respectively, so that the lateral displacement of the special-shaped part 19 is fixed. Moreover, since the M-shaped push plate 17 is arranged in cooperation with the special-shaped part 19, when the special-shaped part 19 is clamped laterally, it can effectively prevent the special-shaped part 19 from being clamped due to uneven force during the clamping process, thereby preventing the clamping from being offset and unable to clamp the special-shaped part 19, or preventing the clamping from deviating, thereby affecting the processing of the special-shaped part 19.

[0024] Among them, a machine tool turning tool 21 is fixedly connected to the inside of the CNC machine tool body 1, and the machine tool turning tool 21 is arranged corresponding to the special-shaped part 19. During the processing, since the machine tool turning tool 21 is arranged corresponding to the special-shaped part 19, the displacement distance of the machine tool turning tool 21 can be effectively reduced during the processing, thereby improving the processing efficiency.

[0025] Working principle:

[0026] The special-shaped part 19 is placed on the first mounting block 2 and the second mounting plate 12, and the second motor 13 is started. The second motor 13 is started to drive the second reciprocating screw rod 14 to rotate. The second reciprocating screw rod 14 rotates and drives the push plate 16 to move through the internal thread 15. Since the push plate 16 and the M-shaped push plate 17 are in contact with the surface of the first mounting block 2, the first mounting block 2 surface limits it and will not rotate synchronously with the second motor 13, so that the push plate 16 moves to push the M-shaped push plate 17 to move. The M-shaped push plate 17 moves and cooperates with one side of the special-shaped part 19. After being pushed to a certain distance, the other side of the special-shaped part 19 is in contact with the limiting plate 22, and the M-shaped push plate 17 is continued to be pushed so that the two sides of the special-shaped part 19 are clamped by the M-shaped push plate 17 and the limiting plate 22 respectively, thereby fixing the lateral displacement of the special-shaped part 19, preventing the special-shaped part 19 from being clamped due to uneven force during the clamping process, thereby preventing the clamping offset from failing to clamp the special-shaped part 19, or the clamping deviation from affecting the clamping of the special-shaped part 19. To process the part 19, after the lateral position of the special-shaped part 19 is clamped, the first motor 4 is started, and the output end of the first motor 4 rotates to drive the rotating shaft 5 to rotate, and the rotating shaft 5 rotates to drive the first bevel gear 6 to rotate, and the first bevel gear 6 rotates to drive the second bevel gear 7 meshing with it to rotate, and the second bevel gear 7 rotates to drive the first reciprocating screw 8 to rotate inside the limit block 3, and the limit block 3 rotates to drive the first moving block 9 to move, and the first moving block 9 moves to drive the clamping plate 10 to move, and the clamping plate 10 moves to match the contour of the special-shaped part 19 to clamp the special-shaped part 19. Since the clamping plate 10 is designed to match the shape of the special-shaped part 19, it can perfectly match the special-shaped part 19 when clamping the special-shaped part 19, thereby perfectly adapting to the special-shaped part, preventing deviation during processing of the special-shaped part, affecting the processing accuracy, affecting the practicality of the subsequent processed parts, and causing the product to be unqualified. After clamping is completed, start the machine tool turning tool 21 to process the special-shaped part 19.
