[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] To provide a clearer and more accurate understanding of the present invention, a detailed description will now be provided in conjunction with the accompanying drawings. The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, but is for illustrative purposes only and is not a drawing based on the original dimensions.

[0033] Existing machine tools (such as lathes) do not have auxiliary material racks. For some rotating bodies with large weight (such as wheel hubs), when operators manually transfer rotating bodies, the large weight of the rotating bodies will affect the efficiency of loading and unloading.

[0034] To solve the above technical problems, please refer to Figure 1 and 2 This utility model provides a machine tool body, which is provided with a base 100, a column 200, a crossbeam 300, a spindle 400, a chuck 500, a turret device 600, and an auxiliary loading and unloading device 700. The auxiliary loading and unloading device 700 is disposed on the side of the column 200, and the loading and unloading end 701 of the auxiliary loading and unloading device 700 is located below the crossbeam 300. In at least one working position of the spindle 400, the chuck 500 can be moved to above the loading and unloading end 701 of the auxiliary loading and unloading device 700.

[0035] It is understood that the loading / unloading end 701 of the auxiliary loading / unloading device 700 is used for loading or unloading workpieces. Since the loading / unloading end 701 of the auxiliary loading / unloading device 700 is located at the loading / unloading position of the spindle 400 and the chuck 500, the operator can place the workpiece to be processed on the loading / unloading end 701 of the auxiliary loading / unloading device 700, which has a certain height, during loading. Then the chuck 500 clamps the workpiece to be processed, eliminating the need for the operator to lift the workpiece directly from the ground onto the chuck 500, thus facilitating loading. After the workpiece is processed, the chuck 500 places the processed workpiece on the loading / unloading end 701 of the auxiliary loading / unloading device 700, which has a certain height, and the operator can then remove the processed workpiece from the loading / unloading end 701 of the auxiliary loading / unloading device 700, which has a certain height. This eliminates the need for the operator to remove the processed workpiece from the chuck 500, which is at the highest position, thus facilitating unloading.

[0036] To facilitate loading and unloading operations, the auxiliary loading / unloading device 700 includes a loading rack 710 and an unloading rack 720. Both the loading rack 710 and the unloading rack 720 are three-dimensional structures with a certain height, and their loading / unloading ends 701 are within the movement range of the chuck 500. The upper surface of the loading rack 710 is flush with the upper surface of the unloading rack 720, facilitating the transfer of workpieces between them and allowing for easy movement of workpieces between them. The loading rack 710 provides workpieces to the chuck 500, which can move to a position close to the top of the loading rack 710 to grip the workpieces. The unloading rack 720 is used to unload the workpieces removed from the chuck 500, and the unloading rack 720 can receive the workpieces unloaded from the chuck 500.

[0037] To facilitate long-distance movement of workpieces and to enable the movement of workpieces with larger diameters, the lengths of the loading rack 710 and unloading rack 720 need to be increased. Specifically, the loading and unloading ends 701 of the loading rack 710 and the unloading rack 720 are projected vertically within the vertical projection of the base 100. The loading rack 710 and the unloading rack 720 also have a transport section and a distal end, the vertical projections of which are located outside the vertical projection of the base 100. This extends the loading rack 710 and the unloading rack 720 to the outside of the base 100, thereby increasing the length of the loading rack 710 and the unloading rack 720, increasing the travel distance of the workpiece on the loading rack 710 and the unloading rack 720, and enabling the placement of workpieces with larger diameters.

[0038] To facilitate loading and unloading operations from a fixed position without requiring operator movement, thereby improving efficiency, the loading rack 710 and the unloading rack 720 are specifically arranged in a V-shape. In this embodiment, one end of the loading rack 710 is positioned close to one end of the unloading rack 720. In other embodiments, one end of the loading rack 710 and one end of the unloading rack 720 may be connected to each other. The loading and unloading ends 701 of the loading rack 710 and the unloading rack 720 are located at the intersection of the V-shape. One of the loading rack 710 and the unloading rack 720 is located below the end of the crossbeam 300, and the other is located below the front side of the crossbeam 300. This allows the operator to stand inside the intersection of the V-shape without moving, ensuring that both the loading rack 710 and the unloading rack 720 are within the operator's operating range, facilitating fixed-point loading and unloading.

[0039] For convenient remote control of workpieces placed on the loading rack 710 and unloading rack 720, please refer to... Figure 4The loading rack 710 and / or the unloading rack 720 are provided with a conveyor belt 702 and a drive device 703 for driving the conveyor belt 702. The drive device 703 is located at the end of the loading rack 710 and / or the unloading rack 720 away from the loading and unloading end 701. The operator can realize the forward and reverse rotation and stop of the conveyor belt 702 by connecting or disconnecting the power supply of the drive device 703 in the forward and reverse directions.

[0040] It is understandable that, since the drive unit 703 occupies a certain amount of space, the drive unit 703 is set at a position far away from the loading and unloading end 701, so as to avoid installing structural components at the loading and unloading end 701 as much as possible, thereby freeing up space at the loading and unloading end 701 and preventing too many structural components from interfering with loading and unloading.

[0041] For easier movement of workpieces on the loading rack 710 and unloading rack 720, please refer to... Figure 5 The loading rack 710 and / or the unloading rack 720 are equipped with a frame 704 and a plurality of rollers 705 rotatably mounted on the frame 704. The rotation axes of the plurality of rollers 705 are parallel to each other, and the plurality of rollers 705 are spaced apart in the horizontal direction. It can be understood that the rollers 705 can be unpowered rollers or powered rollers. The unpowered rollers replace the friction between the loading rack 710 and the workpiece, and between the unloading rack 720 and the workpiece, with rolling friction. The choice can be made according to the actual situation. Whether it is an unpowered roller or a powered roller, it is convenient for the operator to move the workpieces on the loading rack 710 and the unloading rack 720.

[0042] To reduce the number of structural components on the loading rack 710 and unloading rack 720, please refer back to [link / document]. Figure 1 The loading rack 710 includes a first mounting member 711 and a plurality of first support legs 712 supported below the first mounting member 711. Two first sliding plates 7111 protrude from the top of the first mounting member 711, and workpieces are placed on the first sliding plates 7111 for movement. It is understood that lubricating oil or rollers can be provided on the first sliding plates 7111 to prevent scratches when the workpiece moves on them. The unloading rack 720 includes a second mounting member 721 and a plurality of second support legs 722 supported below the second mounting member 721. Two second sliding plates 7211 protrude from the top of the second mounting member 721, and workpieces are placed on the second sliding plates 7211 for movement. It is understood that lubricating oil or rollers can be provided on the second sliding plates 7211 to prevent scratches when the workpiece moves on them.

[0043] To make the best use of the space on base 100, please refer to... Figure 1 and 2The column 200 is disposed on the rear side of the base 100, and the crossbeam 300 is disposed on the column 200. The length of the crossbeam 300 is longer than the length of the column 200, and the length of the crossbeam 300 is less than or equal to the length of the base 100. The spindle 400 is slidably disposed on the front side of the crossbeam 300, and the spindle 400 extends vertically. The machine tool body is a vertical machine tool body. In some other embodiments, the spindle 400 can be slidably disposed on the top surface of the crossbeam 300, and the machine tool body is a horizontal machine tool body.

[0044] The chuck 500 is mounted on the spindle 400, which drives the chuck 500 to rotate. The turret device 600 is located on the front side of the base 100. It can be understood that the turret device 600 is also located in front of the column 200, so that the machining position of the workpiece is also located in front of the column 200, improving the stability of the spindle 400 machining and ensuring the machining accuracy of the machine tool body.

[0045] To improve the space utilization of the machine tool body, please review... Figure 1 and 3 A channel T can be formed between the crossbeam 300, the column 200, and the base 100. The channel T is used to accommodate part of the loading rack 710 or part of the unloading rack 720. Specifically, one end of the crossbeam 300 is suspended above the column 200. The crossbeam 300, the column 200, and the base 100 enclose a channel T with an opening on the side. A part of the auxiliary loading / unloading device 700 is disposed in the channel T. Specifically, a part of the loading rack 710 or a part of the unloading rack 720 is disposed in the channel T. It can be understood that the length of the crossbeam 300 is at least 1 / 3 longer than the length of the column 200, so that the length of the channel T along the extension direction of the crossbeam 300 is large enough to accommodate the width of the loading rack 710 or the width of the unloading rack 720. The height of the channel T is equal to the height of the column 200. The height of the column 200 can accommodate the sum of the heights of the loading rack 710 and the workpiece, and the height of the column 200 can also accommodate the sum of the heights of the unloading rack 720 and the workpiece.

[0046] By adding a loading rack 710 and a unloading rack 720, and forming a channel T adjacent to the column 200 under the crossbeam 300, a part of the auxiliary loading / unloading device 700 (e.g., a part of the loading rack 710 or a part of the unloading rack 720) is set in the channel T. This allows for the convenient placement and sliding of heavy workpieces on the loading rack 710 and the unloading rack 720, facilitating loading and unloading for the operator. On the other hand, it also conceals part of the structure of the loading rack 710 or the unloading rack 720, thereby improving the compactness of the machine tool body structure.

[0047] To improve the protection of the channel T and the loading rack 710 or unloading rack 720 located within the channel T while increasing the utilization rate of the machine tool body space, please refer to... Figure 1 The machine tool body also includes a cover 800, which protects the area above the passage T. The cover 800 is located below the crossbeam 300 and at the top of the passage T, with its extension direction parallel to that of the passage T. The cover 800 includes a top plate and two side plates located on either side of the bottom of the top plate. The top plate is horizontally positioned, and the side plates are vertically positioned. Chips and cutting fluid falling onto the top plate are routed to the base 100 via the two side plates, thus preventing them from falling onto the loading rack 710 or unloading rack 720 within the passage T. The top plate may have a certain degree of inclination to facilitate the movement of chips and cutting fluid.

[0048] To isolate the machining area in front of the channel T and the crossbeam 300 as much as possible, and thus prevent cutting fluid and chips from contaminating the internal structural components of the channel T along the front-to-back direction (the direction perpendicular to the front side of the crossbeam 300) during machining, please refer to [reference needed]. Figure 1 The front side of the crossbeam 300 is provided with a telescopic cover 900 that blocks or releases the channel T. The loading rack 710 is located in front of the telescopic cover 900 and is located in front of the base 100 and near a bend in the channel T. The unloading rack 720 is located behind the telescopic cover 900. The turret device 600 is located in front of the base 100 and away from another bend in the channel T. The loading rack 710 and the turret device 600 are spaced apart. The base 100 is provided with a chip discharge port 102 between the loading rack 710 and the turret device 600. The chip discharge port 102 is used to discharge the chips and cutting fluid generated during workpiece processing.

[0049] The telescopic cover 900 extends vertically. It can be understood that when there is a gap between the loading rack 710 and the unloading rack 720, the telescopic cover 900 is located within the gap. When the loading rack 710 and the unloading rack 720 are connected, the telescopic cover 900 is provided with a clearance opening to avoid the loading rack 710 or the unloading rack 720. When the telescopic cover 900 is extended, the loading rack 710 or the unloading rack 720 is positioned within the clearance opening.

[0050] After a channel T is provided between the beam 300, the column 200, and the base 100, the cross-sectional area of ​​the column 200 is smaller than that of the beam 300. In order to improve the strength of the connection between the column 200 and the base 100, the cross-sectional area of ​​the bottom of the column 200 in the horizontal direction is larger than that of the top of the column 200. The bottom of the column 200 is connected to the base 100. By increasing the size of the bottom of the column 200, the contact area between the column 200 and the base 100 can be increased. This allows for the provision of more mounting holes 210 while ensuring that the column 200 has a certain degree of rigidity.

[0051] The following describes the specific connection method between the column 200 and the base 100. Please refer to [link / reference]. Figure 2 and 3 The machine tool body also includes fasteners. The bottom periphery of the column 200 is provided with mounting holes 210, and the base 100 is provided with mating holes 101 corresponding to the mounting holes 210. The fasteners lock the column 200 and the base 100 through the mounting holes 210 and the mating holes 101. It can be understood that the fasteners can be bolts, the mounting holes 210 can be through holes, and the mating holes 101 can be threaded holes.

[0052] Please refer to Figure 2 and 3 A reinforcing rib 220 protrudes from the front side of the column 200 near the base 100. At least two mating holes 101 are vertically and spaced apart within the reinforcing rib 220. The cross-sectional area of ​​the reinforcing rib 220 increases sequentially from top to bottom, and the bottom end 221 of the reinforcing rib 220 is vertically flush. By providing the reinforcing rib 220, not only is a structural foundation provided for the opening of the mounting hole 210, but the rigidity of the column 200 is also improved. In addition, the column 200 and the crossbeam 300 are integrally formed, thereby improving the stability of the connection between the column 200 and the crossbeam 300.

[0053] The following section describes the detailed structure of the DotTorch 600; please refer back to [link / reference needed]. Figure 1The turret device 600 includes a housing 610, a rotating tool holder 620 rotatably mounted on the housing 610, a plurality of tools 640 disposed on the outer periphery of the rotating tool holder 620, and a driving member 630 for driving the rotating tool holder 620 and the plurality of tools 640 to rotate relative to the housing 610. The driving member 630 is close to the periphery of the base 100, and the rotating tool holder 620 is located near the middle position of the front side of the base 100. The rotation axis of the rotating tool holder 620 is parallel to the extension direction of the crossbeam 300. The housing 610 is fixedly installed on the front side of the base 100, and the housing 610 and the loading rack 710 are respectively located on both sides of the chip discharge port 102, thereby facilitating the discharge of chips and cutting fluid generated by the tools 640 during processing through the chip discharge port 102 to the outside of the base 100.

[0054] The machine tool body described above includes a base 100, a column 200, a crossbeam 300, a spindle 400, a chuck 500, a turret device 600, and an auxiliary loading / unloading device 700. The column 200 is located on the rear side of the base 100, the crossbeam 300 is located on the column 200, the spindle 400 is slidably mounted on the front side of the crossbeam 300, the chuck 500 is mounted on the spindle 400, and the spindle 400 is used to drive the chuck 500 to rotate. The turret device 600 is located on the front side of the base 100, and the auxiliary loading / unloading device 700 is located on the side of the column 200. The loading / unloading end 701 of the auxiliary loading / unloading device 700 is located below the crossbeam 300, and in at least one position of the spindle 400, the chuck 500 can move to above the loading / unloading end 701 of the auxiliary loading / unloading device 700.

[0055] The loading / unloading end 701 of the auxiliary loading / unloading device 700 is used for loading or unloading workpieces. Since the loading / unloading end 701 of the auxiliary loading / unloading device 700 is located at the loading / unloading position of the spindle 400 and the chuck 500, the operator can place the workpiece to be processed on the loading / unloading end 701 of the auxiliary loading / unloading device 700 during loading, and then the chuck 500 clamps the workpiece to be processed. The operator does not need to directly install the workpiece to be processed onto the chuck 500, which is convenient for loading. After the workpiece is processed, the chuck 500 places the processed workpiece on the loading / unloading end 701 of the auxiliary loading / unloading device 700, and then the operator removes the processed workpiece from the loading / unloading end 701 of the auxiliary loading / unloading device 700. The operator does not need to directly remove the processed workpiece from the chuck 500, which is convenient for unloading.

[0056] This utility model also provides a machine tool, including an outer sheet metal protective cover and the aforementioned machine tool body, wherein the outer sheet metal protective cover is disposed on the base of the machine tool body.
