Abstract
Description
Technical Field
[0001] This invention relates to the field of turning equipment technology, and in particular to a movable tool holder for turning large workpieces. Background Technology
[0002] The tool post on a lathe is a crucial component for mounting cutting tools. Many tool posts also directly participate in the cutting process, such as the square tool post on a horizontal lathe, the turret tool post on a turret lathe, and the return wheel tool post on a return wheel turret lathe. These tool posts not only hold the cutting tools but also directly participate in the cutting process, bearing immense cutting forces. In traditional lathes, the tool post is typically mounted on the feed mechanism, which controls the relative position between the tool and the workpiece to complete the machining. For ordinary lathes used for rotor or workpiece external turning, once the tool post is fixed, the maximum machining radius of the lathe limits the machining of workpieces to specific dimensions. For large-diameter workpieces, turning operations are impossible. Summary of the Invention
[0003] The purpose of this invention is to provide a movable tool holder for turning large workpieces, in order to solve the problems in the prior art.
[0004] This invention provides a movable tool holder for turning large workpieces, comprising: The base is detachably mounted on the workpiece rotation drive device; A support frame, which is mounted on the base; A longitudinal feed mechanism, which is mounted on the support frame, is used to control the longitudinal feed of the tool; A transverse feed mechanism, which is mounted on the longitudinal feed mechanism, is used to control the tool to perform transverse feed; The tool holder body is mounted on the transverse feed mechanism and is used to clamp the tool.
[0005] According to the present invention, a movable tool holder for turning large workpieces includes a base comprising a front side plate, a left side plate, a rear side plate, a right side plate, and a top panel.

[0008] According to the present invention, a movable tool holder for turning large workpieces is further provided on the base, and the counterweight frame is fixedly connected to the support frame.
[0009] According to the present invention, a movable tool holder for turning large workpieces has a mounting base plate fixedly installed on the top plate of the base, and the counterweight frame and the support frame are both fixedly installed on the mounting base plate.
[0010] According to the present invention, a movable tool holder for turning large workpieces includes a counterweight frame comprising a lower counterweight frame and an upper counterweight frame. The lower counterweight frame includes two parallel first counterweight uprights and a first counterweight top plate, the first counterweight top plate being fixed to the top of the two first counterweight uprights.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to 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 are within the scope of protection of the present invention.
[0019] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention 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 limiting this invention.
[0020] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0021] like Figures 1 to 5As shown, the movable tool holder for turning large workpieces according to an embodiment of the present invention includes a base 1, a support frame 2, a longitudinal feed mechanism 3, a transverse feed mechanism 4, and a tool holder body 5. The base 1 is detachably mounted on a workpiece rotation drive device (not shown). The support frame 2 is mounted on the base 1 and supports the longitudinal feed mechanism 3, the transverse feed mechanism 4, and the tool holder body 5. The longitudinal feed mechanism 3, mounted on the support frame 2, controls the longitudinal feed of the tool to precisely control the relative position of the workpiece and the tool, ensuring the accuracy of the machining dimensions. The transverse feed mechanism 4, mounted on the longitudinal feed mechanism 3, controls the transverse feed of the tool to precisely control the relative position of the workpiece and the tool, ensuring the accuracy of the machining dimensions. The tool holder body 5, mounted on the transverse feed mechanism 4, is used to clamp the tool.
[0022] Therefore, the movable tool holder for turning large workpieces according to the present invention can install the base 1 on the corresponding workpiece rotation drive device that can meet the turning size requirements of the workpiece according to actual use needs, and is no longer limited by the maximum machining radius of the lathe itself. By integrating the tool holder body 5 on the longitudinal feed mechanism 3 and the transverse feed mechanism 4, the tool holder is movable, thereby easily matching with the workpiece rotation drive device to meet the machining requirements of the outer circle and end face of large diameter workpieces.
[0023] The workpiece rotation drive device only needs to be able to reliably and securely clamp the workpiece and drive it to rotate, and its size needs to meet the requirements for machining the outer diameter and end face of large-diameter workpieces after the movable tool holder is installed. Therefore, the movable tool holder of this embodiment can be used in conjunction with various existing rotary drive devices that meet the above requirements, making it more versatile.
[0024] Specifically, the base 1 includes a front side plate, a left side plate, a rear side plate, a right side plate, and a top panel. The front side plate, left side plate, rear side plate, and right side plate together form a first rectangular frame, and the top panel is fixed to the top of the first rectangular frame. This structural form of the base ensures the structural stability and reliability of the base 1, thereby providing a stable and reliable mounting foundation for the support frame 2, the longitudinal feed mechanism 3, the transverse feed mechanism 4, and the tool holder body 5.
[0025] Multiple connecting lugs can be provided at the bottom of the base 1 to facilitate connection and installation with the corresponding workpiece rotation drive device.
[0026] Specifically, the support frame 2 includes a front support plate, a left support plate, a rear support plate, a right support plate, and a top support plate. The front support plate, left support plate, rear support plate, and right support plate together form a second rectangular frame, and the top support plate is fixed to the top of the second rectangular frame. This structural form of the support frame 2 ensures its structural stability and reliability, thereby providing stable and reliable support for the longitudinal feed mechanism 3, the transverse feed mechanism 4, and the tool holder body 5.
[0027] The height of the support frame 2 is set to ensure that the cutting tool can be aligned with the center of the pre-machined workpiece.
[0028] Furthermore, a counterweight frame is installed on the base 1, and this counterweight frame is connected and fixed to the support frame 2. By setting up the counterweight frame, the overall structural stability of the movable tool post can be improved, preventing the movable tool post from shaking due to an unstable center of gravity during processing.
[0029] The counterweight frame includes a lower counterweight frame 6 and an upper counterweight frame 7. The lower counterweight frame 6 includes two parallel first counterweight uprights 601 and a first counterweight top plate 602, with the top plate 602 fixed to the top of the two first counterweight uprights 601. The upper counterweight frame 7 is fixed to the top plate 602 and includes three parallel second counterweight uprights 701 and a second counterweight top plate 702, with the top plate 702 fixed to the top of the three second counterweight uprights 701.
[0030] Specifically, a mounting base plate 8 is fixedly installed on the top plate of the base 1, and the counterweight frame and support frame 2 are both fixedly installed on the mounting base plate 8 to further improve the connection stability between the counterweight frame and the support frame 2, thereby improving the overall structural stability of the mobile tool holder.
[0031] The first lifting ring 201 is installed on the support frame 2, and the second lifting ring 603 is installed on the lower counterweight frame 6, which facilitates the lifting of the mobile tool holder during its relocation and installation.
[0032] Specifically, the longitudinal feed mechanism 3 includes a longitudinal guide rail 301, a longitudinal sliding seat 302 that slides with the longitudinal guide rail 301, and a first lead screw and nut drive mechanism 303 that drives the longitudinal sliding seat 302 to move along the longitudinal guide rail 301. The longitudinal guide rail 301 is fixedly installed on the top of the support frame 2. By controlling the action of the first lead screw and nut drive mechanism 303, the tool on the tool holder body 5 can be controlled to perform longitudinal feed motion.
[0033] Specifically, the transverse feed mechanism 4 includes a transverse guide rail 401, a transverse sliding seat 402 that slides with the transverse guide rail 401, and a second lead screw and nut drive mechanism 403 that drives the transverse sliding seat 402 to move along the transverse guide rail 401. The transverse guide rail 401 is mounted on the longitudinal sliding seat 302, and the tool holder body 5 is mounted on the transverse sliding seat 402. By controlling the action of the second lead screw and nut drive mechanism 403, the tool on the tool holder body 5 can be controlled to perform transverse feed motion.
[0034] The first lead screw and nut drive mechanism 303 and the second lead screw and nut drive mechanism 403 can be electric lead screw and nut drive mechanisms.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
