[0031] The following disclosure provides many different implementation methods or examples for different schemes of implementing this application.

[0032] like Figures 1 to 4 As shown, a first aspect of this application provides a machine tool body. As... Figures 1 to 3 As shown, the machine tool body includes a base 1, a first column 2 and a second column 3 located at the rear of the base 1, a crossbeam 4 mounted on the upper ends of the first column 2 and the second column 3, a spindle box 5 located on the front side of the crossbeam 4, and a Y-axis motion component 6 mounted on the base 1 along the front-rear direction. The base 1 is the basic support component of the machine tool body; the first column 2 and the second column 3 support the crossbeam, forming the frame structure of the machine tool and providing a mounting base for the crossbeam and the spindle box; the crossbeam 4 provides the mounting position for the spindle box 5 and supports its weight; the spindle box 5 is mounted on the front side of the crossbeam and contains a spindle for driving the tool rotation to achieve cutting; the Y-axis motion component 6 realizes the workpiece feed in the Y-axis direction.

[0033] Meanwhile, a chip removal groove 8 is provided above the base 1 along the front-to-back direction of the base 1. A spiral rod 9 is installed inside the chip removal groove 8. The chip removal groove 8 is used to collect chips generated during cutting. The rotation of the spiral rod pushes the chips along the chip removal groove, thereby expelling the chips from the machine tool body. The chip removal groove 8 is located between the Y-axis moving component 6 and the first column 2 and / or between the Y-axis moving component 6 and the second column 3, facilitating the collection of chips generated during machine tool processing. A mesh pedal 7 is installed on top of the chip removal groove 8. The mesh pedal 7 is laid along the front-to-back direction of the base 1 on the top surface of the base 1, adhering to the top surface of the base 1. The mesh pedal 7 enables automatic filtering of large-sized chips, preventing them from clogging the chip removal channel. Simultaneously, the close fit between the mesh pedal 7 and the top surface of the base 1 forms a physical barrier, effectively preventing external debris such as workpieces and tools from falling into the chip removal groove 8 and protecting components such as the spiral rod 9 from accidental impact damage. In addition, the grid pedal 7 provides a stable operating surface, making it easier for staff to enter the machine tool body for routine maintenance, tool replacement and other operations, thereby improving the safety and convenience of using the machine tool body.

[0034] like Figure 3 As shown, the front end of the screw rod 9 is connected to the motor 10 for driving, providing power for the chip removal rotation of the screw rod 9; the base 1 extends forward to form an extension 11 extending out of the base 1, and the motor 10 is located on the lower side of the extension 11, making full use of the space below the extension 11 of the base 1, providing an independent installation space for the motor 10, and avoiding spatial interference with other parts of the machine tool body; and the motor 10 is parallel to and overlaps with the screw rod 9 in the length direction, so that the motor 10 can provide power to the screw rod 9 more directly and efficiently, while saving space and making the overall structure of the machine tool more compact.

[0035] like Figure 3 and Figure 4 As shown, a connecting body 91 is provided at the front end of the screw rod 9. The outer circumference of the connecting body 91 is fixedly connected to the inner ring of the screw rod 9. When the motor transmits power to the connecting body 91, it drives the connecting body 91 to rotate. Since the connecting body 91 is fixedly connected to the screw rod 9, the rotation of the connecting body 91 will drive the screw rod 9 to rotate synchronously, achieving a good connection and transmission effect. In addition, the connecting body 91 can be designed and adjusted according to different motors and screw rod 9 specifications to better match the two, improving the versatility and adaptability of chip removal.

[0036] like Figure 4As shown, the front end of the screw rod 9 is connected to the motor 10 via a transmission mechanism 13. The transmission mechanism 13 includes a driving wheel 131 located in front of the output end of the motor 10 and a driven wheel 132 located in front of the connecting body 91. The driving wheel 131 is connected to the driven wheel 132 via a chain or belt. When the motor 10 starts, its output end drives the driving wheel 131 to rotate. The driving wheel 131 drives the driven wheel 132 via a chain or belt, causing the driven wheel 132 to rotate synchronously with the driving wheel 131. The driven wheel 132 is fixedly connected to the connecting body 91, and the connecting body 91 is fixedly connected to the screw rod 9. Therefore, the rotation of the driven wheel 132 drives the screw rod 9 to rotate together, thereby realizing the chip removal action. In addition, the transmission mechanism 13 can also select driving wheels 131 and driven wheels 132 of different diameters as needed to achieve different transmission ratios to meet the different speed requirements of the screw rod 9, that is, it can adapt to different chip removal volume requirements. The driving wheel 131 and the driven wheel 132 are on the same plane, that is, the rotation axes of the driving wheel 131 and the driven wheel 132 are parallel, which allows the chain or belt to be smoothly transmitted in a plane, ensuring the straightness and stability of the power transmission path.

[0037] like Figure 1 and 4 As shown, a mounting plate 12 is fixedly installed at the front end of the base 1, and the mounting plate 12 is fixedly connected to the front end of the extension 11. The motor 10 is fixed on the mounting plate 12, and the output end of the motor 10 passes through the mounting plate 12 and is connected to the drive wheel 131. The connecting body 91 passes through the mounting plate 12 and is connected to the driven wheel 132. The mounting plate 12 allows the motor 10 to make full use of the space under the extension 11 of the base 1 while also being stably connected to the base 1, ensuring that the motor 10 will not shift during operation. The connection between the output end of the motor 10 and the drive wheel 131, and the connection body 91 and the driven wheel 132, ensures accurate alignment and transmission precision between the drive wheel 131 and the driven wheel 132, allowing power to be reliably transmitted from the motor 10 to the screw 9, thus improving the chip removal efficiency of the screw 9.

[0038] like Figure 2 As shown, the chip removal groove 8 has a V-shaped groove structure with a rounded bottom. The spiral rod 9 is an integral hollow spiral structure, and its outer diameter matches the curvature of the bottom of the V-shaped groove. The V-shaped groove design of the chip removal groove 8 allows chips to more easily accumulate at the bottom under gravity. Furthermore, the rounded bottom curvature matches the outer diameter of the spiral rod 9, enabling it to maximize contact with the chips at the bottom of the V-shaped groove. The rotation of the spiral rod 9 more effectively propels the chips, improving chip removal efficiency and reducing chip accumulation within the chip removal groove 8. Simultaneously, the integral hollow spiral structure of the spiral rod 9 ensures structural strength while reducing its weight, thus lowering the load on the motor 10 and achieving efficient chip removal.

[0039] like Figure 2 As shown, the surface of the chip discharge groove 8 is fitted with a stainless steel plate 81, which has good wear resistance, corrosion resistance, and high temperature resistance, protecting the base material of the chip discharge groove 8 and extending its service life. Meanwhile, the stainless steel plate 81 extends from the rear end of the base 1 along the front-rear direction, providing a continuous and smooth discharge channel for the chips. Driven by the screw rod 9, the chips move along the chip discharge groove 8 and are guided to a designated collection position when passing the extended portion of the stainless steel plate 81, preventing chips from scattering and facilitating centralized chip processing.

[0040] like Figure 2 As shown, the mesh pedal 7 includes horizontally spaced mesh pieces 71 and vertically spaced connecting rods 72. The mesh pieces 71 and the connecting rods 72 are fixedly connected to form an integral mesh structure, which can filter large-sized chips, effectively prevent the chip removal groove 8 from clogging, and effectively prevent external debris such as workpieces and tools from falling into the chip removal groove 8, protecting components such as the screw rod 9 from accidental impact damage. The connecting rods 72 support and connect the mesh pieces 71 in the vertical direction, enhancing the overall strength and rigidity of the mesh pedal 7, enabling it to withstand the weight of the operator and other external forces that may be generated, providing the operator with a stable standing platform, allowing the operator to maintain balance during operation inside the machine tool body, and reducing operational errors or safety accidents caused by instability.

[0041] like Figure 1 As shown, there are two chip removal grooves 8, one between the Y-axis moving component 6 and the first column 2, and the other between the Y-axis moving component 6 and the second column 3. These grooves facilitate the collection of chips generated by the Y-axis moving component 6, the worktable, and the area near the machining zone, maximizing coverage of areas where waste may be generated. The mesh pedal 7 completely covers the helical rod 9 along the front-to-back direction of the base 1, providing the operator with a stable and safe standing position, preventing accidental stepping on the helical rod 9 and facilitating operator access to the machine tool for operation and observation, thus reducing the risk of accidents.

[0042] A second aspect of this application provides a machine tool. In some embodiments of this application, the machine tool includes a machine tool body as described in one of the preceding embodiments. The Y-axis motion component 6 of the machine tool body includes a guide rail 61, a worktable disposed on the guide rail 61, and a drive mechanism 62 for driving the worktable. A spindle is also disposed inside the spindle box 5, with the working end of the spindle facing the worktable. Since this machine tool has the aforementioned machine tool body, it also has the corresponding effects of the machine tool body, which will not be described again here.

[0043] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
