Description

Technical Field

[0001] This utility model relates to the field of machine tools, and more specifically, to a machine tool body and a machine tool. Background Technology

[0002] In existing CNC lathes with inclined machining surfaces, two moving guide rails are typically provided on the upper surface of the bed. The guide rail for mounting the center device and the guide rail for mounting the saddle are both located on this inclined surface. While this layout increases machining flexibility to some extent, it prevents the installation of chip removal structures on the inclined surface of the bed. Alternatively, if additional chip removal structures are needed on the inclined surface, the width of the bed must be increased, thus increasing the machine tool's size. For example, a utility model patent for an inclined machine tool with a chip removal and drainage structure (application number: CN202221984009.7) provides two guide rails on the inclined machining surface of the bed: one for mounting the tool post and the other for mounting the center device. This makes it difficult for chips generated during machining to be easily discharged from the inclined surface. Furthermore, the guide rails of this machine tool have the same slope as the inclined surface, making them prone to deformation.

[0003] Therefore, the machine tool needs to be improved to facilitate chip removal from the machine tool bed. Utility Model Content

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0043] The first aspect of the present invention provides a machine tool body, with reference to Figure 1 and Figure 2The machine tool includes a base 1, a saddle 2, a first drive unit 3, a spindle 4, and a second drive unit 8. The base 1 serves as the basic support structure for the machine tool body, and its upper surface is divided into a tool preparation area 11 and a machining area 12. The tool preparation area 11 is used for tool configuration and preparation; a first guide rail 13 is provided on the tool preparation area 11 to guide the movement of the saddle 2. The machining area 12 is the main area for workpiece machining, further subdivided into a support area 121 and a cutout area 122. The saddle 2 is movably mounted on the first guide rail 13, and its main function is to support and move the tool to a designated position for workpiece machining. The first drive unit 3 is mounted on the tool preparation area 11 and connected to the saddle 2. Through precise control, the first drive unit 3 can drive the saddle 2 to move smoothly and quickly along the first guide rail 13. The spindle 4 is the core component of the machining area 12 and is fixedly mounted on the support area 121. The axis of the spindle 4 is parallel to the extension direction of the first guide rail 13, ensuring machining accuracy and stability. A chuck 5 is mounted on the spindle 4 to securely clamp the workpiece to be machined. The chuck 5 is located on one side of the cutout area 122 of the spindle 4. During machining, the saddle 2 is moved to the position of the chuck 5, so that the tool on the saddle 2 machines the workpiece on the chuck 5, and the resulting chips fall directly into the cutout area 122 and are discharged from the machine body through the discharge channel of the cutout area 122. The second drive unit 8 is mounted on the base 1 and connected to the spindle 4. By driving the rotation of the spindle 4 through the second drive unit 8, precise machining of the workpiece can be achieved.

[0044] Below the hollowed-out area 122 of the machining area 12, a drainage channel is specially designed to collect and discharge waste materials, coolant, and other substances generated during the machining process. Furthermore, the side of the hollowed-out area 122 is designed as an inclined surface 14, which gradually slopes down from the edge of the hollowed-out area 122 towards the drainage channel. This design not only facilitates the smooth discharge of waste materials but also effectively prevents waste materials from accumulating inside the machine tool, thereby maintaining the cleanliness and efficient operation of the machine tool.

[0045] Before machining begins, the operator first selects a suitable tool in the tool preparation area 11 and mounts it on the saddle 2. Under the precise control of the first drive unit 3, the saddle 2 moves along the first guide rail 13 to the predetermined position, ready for machining. The workpiece to be machined is securely clamped on the chuck 5 on the spindle 4. By adjusting the clamping force of the chuck 5, the stability and safety of the workpiece during machining are ensured. The second drive unit 8 is activated to drive the spindle 4 to rotate. According to the machining requirements, the positions of the saddle 2 and the tool are adjusted by the first drive unit 3 to precisely machine the workpiece. During machining, waste material and coolant are smoothly discharged through the drainage channel below the cutter area 122, keeping the machine tool clean and operating efficiently. After machining is completed, the second drive unit 8 is turned off, stopping the rotation of the spindle 4. The operator can then easily remove the machined workpiece and proceed to the next step of operation or inspection.

[0046] This invention features a tool-feeding area 11 and a machining area 12 arranged side-by-side on the upper surface of the base 1 for machining. The tool-feeding area 11 has a movable saddle 2 equipped with a cutting tool. The machining area 12 does not have guide rails but is instead designed with a hollow structure. When the spindle 4 and the cutting tool work together, the generated chips can be smoothly discharged from the hollow area 122. This layout, with one side being the area for tool movement and the other side being the workpiece machining area 12, improves the overall cleanliness of the machine tool body and makes chip removal more convenient.

[0047] In one specific implementation, reference is made to Figure 1 and Figure 2 The first guide rail 13 adopts a dual-track design, consisting of a first track 131 and a second track 132 arranged parallel to each other at intervals. This design not only improves the stability of the movement of the saddle 2 but also makes the machine tool body more robust and durable. The first track 131 is located on the side away from the machining area 12, and its position is higher than that of the second track 132. The second track 132 is arranged parallel to the first track 131, jointly supporting and guiding the movement of the saddle 2. The extension range of the first track 131 and the second track 132 matches the range of the hollow area 122. This means that during the movement of the saddle 2, the space below it remains consistent with the hollow area 122, thereby ensuring the smooth discharge of waste material and coolant.

[0048] The saddle 2 carries the cutting tool and is driven by the first drive component 3 to move along the first guide rail 13. The first drive component 3 is installed in the tool preparation area 11 and connected to the saddle 2, enabling the saddle 2 to move smoothly and quickly on the first guide rail 13. Because the first guide rail 13 adopts a double-track design, the movement of the saddle 2 is more stable and smooth. Simultaneously, since the extension range of the first track 131 and the second track 132 matches the hollowing area 122, it ensures the smooth discharge of waste material and coolant, further improving the machining efficiency and cleanliness of the machine tool body.

[0049] In the prior art, the guide rails on the inclined surface of the machine tool are inclined, with the guide rail surface inclined at the same angle as the inclined surface. This inclined guide rail configuration means that the force on the guide rail is mainly on the side. When the guide rail is subjected to the pressure of the saddle, it will deform or tend to deform, especially at high temperatures (see patent CN202221984009.7). In this embodiment, the guide rail surfaces of the first rail 131 and the second rail 132 on the base 1 are horizontally arranged. The force on the first guide rail 13 is primarily the vertical pressure of the saddle 2, avoiding lateral force on the first guide rail 13, effectively reducing the deformation tendency and wear of the first guide rail 13.

[0050] In one specific implementation, reference is made to Figure 1 and Figure 2 A turret component 6 and a matching second guide rail 21 were added. The extension direction of the second guide rail 21 is perpendicular to the first guide rail 13, allowing the turret component 6 to move laterally on the saddle 2, thereby enabling the machining of different parts of the workpiece. The turret component 6 is movably mounted on the second guide rail 21, and various cutting tools for machining the workpiece are mounted on it. Guided by the second guide rail 21, the turret component 6 can be precisely moved to a designated position for workpiece machining.

[0051] Before machining begins, the operator selects a suitable cutting tool based on the workpiece's machining requirements and mounts it on the turret component 6. By adjusting the position of the turret component 6 on the second guide rail 21, quick selection and switching of different cutting tools can be achieved. The workpiece to be machined is securely clamped in the chuck 5 on the spindle 4. Adjusting the clamping force of the chuck 5 ensures the stability and safety of the workpiece during machining. The first drive component 3 drives the saddle 2 to move on the first guide rail 13, moving the turret component 6 to a position close to the workpiece. By adjusting the position of the turret component 6 on the second guide rail 21, a suitable cutting tool is selected for machining. Waste material and coolant generated during machining are smoothly discharged through the drainage channel below the hollowed-out area 122, maintaining the cleanliness and efficient operation of the machine tool's interior.

[0052] In one specific implementation, reference is made to Figure 1 and Figure 3 A motor mount 7 was added, which covers the side of the base 1 and together with the base 1 forms a receiving space. The motor mount 7 is used to mount the motor part of the second drive component 8. With the addition of the motor mount 7, the second drive component 8 and related electrical components are better protected and enclosed, which helps to improve the operational stability and service life of the machine tool body. At the same time, this design also helps to reduce noise and vibration during machine tool operation, improving machining accuracy and efficiency.

[0053] Further, refer to Figure 1 , Figure 3 and Figure 4 The second drive component 8 includes a pulley transmission mechanism and a drive motor. The drive motor provides power to drive the pulley transmission mechanism to rotate, which in turn drives the spindle 4 of the machine tool body to rotate. This pulley transmission mechanism mainly includes a driving pulley 81, a driven pulley 82, and a belt 83. The driving pulley 81 is connected to the output shaft of the drive motor; when the drive motor operates, the driving pulley 81 rotates accordingly. The driven pulley 82 is connected to the spindle 4 on the base 1 via a method (such as bearings and connectors); when the driven pulley 82 rotates, the spindle 4 also rotates accordingly. The belt 83 is a high-strength, wear-resistant, and anti-aging V-belt. One end of the belt 83 is fitted onto the driving pulley 81, and the other end is fitted onto the driven pulley 82, forming a closed loop. When the driving pulley 81 rotates, the belt 83 drives the driven pulley 82 to rotate together, thereby transmitting the motor's power to the spindle 4.

[0054] The motor mount 7 is mounted on the base 1, forming a receiving space for accommodating the drive pulley 81 and part of the belt 83. When the belt 83 extends from the receiving space and is fitted onto the driven pulley 82, it effectively transmits the power of the drive motor to the spindle 4 while maintaining the neatness and aesthetics of the machine tool body. Furthermore, the design of the receiving space reduces vibration and noise of the belt 83 during operation, improving the overall performance of the machine tool body.

[0055] Further, refer to Figure 1 , Figure 3 and Figure 5The motor mount 7 includes an end cover 71, side plates 73, a base plate 74, and a fastening plate 75. In specific embodiments, the end cover 71, side plates 73, base plate 74, and fastening plate 75 can be integrally formed. The materials used can be metals with sufficient strength and rigidity, such as steel or aluminum alloy. The end cover 71 has a circular countersunk hole at its center, with a through-hole 72 inside. The size of the 72 matches the drive motor to be installed, ensuring the motor shaft can pass through smoothly. Two side plates 73 are vertically positioned on either side of the end cover 71, forming a stable support structure. The shape and size of the side plates 73 must match the end cover 71 to provide sufficient strength and stability. The base plate 74 is vertically positioned on the bottom surface of the end cover 71, located between the two side plates 73, and together with the side plates 73 and the end cover 71, constitutes the main structure of the motor mount 7. The base plate 74, side plates 73, and end cap 71 surround and enclose to form an open receiving space; in use, this opening facilitates the exit of the drive belt from the receiving space. Each of the two side plates 73 is provided with a fastening plate 75, which is perpendicular to the side plates 73 and parallel to the end cap 71. The fastening plates 75 are provided with fastening holes 76, which are typically designed as threaded holes, to allow the fastening plates 75 to be securely connected to the external structure using bolts or other fasteners.

[0056] The motor mount 7 is configured as a non-plate-like block structure, with the end cover 71, side plate 73, and base plate 74 forming an open receiving space. When the motor mount 7 is installed on the base 1, the motor mount 7 and the base 1 form the receiving space, and the end cover 71 and the base 1 have a certain distance between them. In use, the motor mount 7 and the base 1 form the receiving space. When installing the pulley drive mechanism, this receiving space provides installation space for the drive pulley 81, and the belt 83 can be led out from this receiving space. The drive motor is connected to the drive pulley 81 through the motor hole 72. This receiving space provides installation space for the drive pulley 81 and protects the drive pulley 81. (Refer to...) Figure 3 and Figure 4 .

[0057] In one specific implementation, reference is made to Figure 1 , Figure 4 and Figure 5The fastening holes 76 on the fastening plate 75 are designed as oblong holes, rather than traditional circular holes. Adjustment holes 77, extending through to the fastening holes 76, are provided on the side of the fastening plate 75. The axis of the adjustment hole 77 is collinear with the length direction of the oblong hole. Each fastening hole 76 is paired with an adjustment hole 77, which extends from the outside of the fastening plate 75 to the fastening hole 76. These rectangular through holes are arranged along the length of the side plate 73, allowing for a wider adjustment range to accommodate fastening requirements in different installation scenarios. The oblong hole design increases the flexibility of the fit between the fastening plate 75 and fasteners (such as bolts), making it easier to perform vertical fine-tuning of the motor mount 7 during installation. The adjustment holes 77 are located on the sides of the two fastening plates 75 parallel to the base plate 74 and communicate with the fastening holes 76.

[0058] The machine tool body includes a fixing assembly 9, which comprises two main components: a fixing bolt 91 and an adjusting bolt 92. The fixing bolt 91 is a slender rod-shaped component with a diameter slightly smaller than the width of the fastening hole 76, allowing it to be inserted into the machine base mounting position or the machine tool body from one end of the fastening hole 76. The function of the fixing bolt 91 is to provide an initial fixing point during the installation of the motor base 7, preventing displacement of the motor base 7 during installation. The adjusting bolt 92 is also a rod-shaped component, but its length and diameter can be adjusted as needed. The adjusting bolt 92 can be inserted from the adjusting hole 77 into the fastening hole 76 and abuts against the already inserted fixing bolt 91. By adjusting the position of the adjusting bolt 92 within the fastening hole 76, the position of the motor base 7 can be further fine-tuned to ensure precise alignment with the base 1.

[0059] During assembly, first insert the fixing bolt 91 into the mounting position of the base through one end of the fastening hole 76, ensuring that the fixing bolt 91 is firmly fixed to the base 1, and then tighten the motor mount 7 into the mounting position. Next, insert the adjusting bolt 92 into the fastening hole 76 through the adjusting hole 77, and press it against the fixing bolt 91. By gently tapping or rotating the adjusting bolt 92, the position of the motor mount 7 can be finely adjusted until the required precision is achieved. Once the position of the motor mount 7 is adjusted, use fasteners (such as bolts and nuts) to firmly fix the motor mount 7 to the base 1. (Reference) Figure 3 and Figure 4 In this embodiment, four sets of fixing components 9 are provided. The fixing bolts 91 of each set are inserted into the fastening holes 76 in a vertically distributed manner. The adjusting bolts 92 of each set are inserted from the top and bottom of the fastening plate 75 into the fastening holes 76 and abut against the fixing bolts 91.

[0060] In this embodiment, the base 1 incorporates a fixing component 9, enabling precise installation and fine-tuning of the motor mount 7. This design is particularly suitable for applications requiring extremely high precision from the machine tool body, such as precision machining and optical processing. The use of the fixing component 9 simplifies the installation and adjustment process of the motor mount 7, improving work efficiency and accuracy. Furthermore, the design of the fixing bolt 91 and adjusting bolt 92 allows for fine-tuning in multiple directions, increasing the flexibility and adaptability of the motor mount 7.

[0061] In one specific implementation, reference is made to Figure 1 , Figure 3 and Figure 5 This embodiment incorporates a vibration damping structure (not shown in the figure) to improve the stability of the motor mount 7 and reduce vibration transmission. The vibration damping structure is a device for absorbing and dispersing vibrations. It is located on the side of the fastening plate 75 away from the cover, directly between the fastening plate 75 and the base 1 when the motor mount 7 is mounted on the base 1. The vibration damping structure can be a pad, block, or assembly made of rubber, springs, silicone, or other materials with vibration damping properties. The design of the vibration damping structure must match the shape and size of the fastening plate 75 to ensure a tight fit and sufficient damping effect. When the base 1 vibrates, the vibration damping structure reduces vibration transmission, thereby reducing the vibration of the motor mount 7. The vibration damping structure effectively absorbs and disperses vibrations generated by the machine tool body, thus reducing the problem of motor displacement and wobbling due to lathe vibration.

[0062] In one specific embodiment, the machine tool body further includes a cooling system (not shown in the figure), the output of which leads to the receiving space for cooling. This embodiment describes a highly efficient machine tool body with excellent cooling performance, particularly suitable for long-duration, high-intensity metal cutting operations. The structure of the machine tool body has been expanded to include a cooling system, thereby improving machining efficiency and workpiece quality.

[0063] The primary function of the cooling system is to cool the space housing the machine tool body, thereby reducing the impact of temperatures generated during cutting on the machining accuracy of the machine tool. The cooling medium used in the cooling system is typically cutting fluid, a liquid specifically designed for metal cutting, possessing excellent cooling, lubrication, and cleaning properties. Cutting fluid effectively removes heat generated during cutting, lowering the temperature of the workpiece and tool, while simultaneously reducing friction between the tool and workpiece, improving machining efficiency and workpiece quality. The cooling system includes a cutting fluid delivery nozzle responsible for spraying the cutting fluid in the form of a mist or droplets into the housing space and cutting area for effective cooling and lubrication. Alternatively, air cooling can be used, where air is directed from the cooling system through pipes or nozzles to the motor mount 7 or the housing space.

[0064] A second aspect of this invention provides a machine tool, including a machine tool body as described above, with a protective cover (not shown in the figure) provided on the machine tool body. The protective cover is the outer shell of the machine tool body and covers the machine tool body. An openable / closable protective door is provided on the side of the protective cover corresponding to the machining area 12, through which workpieces and cutting tools can be changed.

[0065] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
