Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The hydraulic machine tool tailstock provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0038] like Figures 1 to 4As shown in the figure, this application embodiment provides a hydraulic machine tool tailstock, including a tailstock mounting base 100, a guide sleeve 300 slidably disposed on the tailstock mounting base 100, and a positioning component fixedly disposed on the guide sleeve 300.

[0039] The tailstock mounting base 100 is also fixedly provided with a drive assembly for driving the guide sleeve 300 to slide relative to the tailstock mounting base 100, and the positioning assembly includes a positioning gripper assembly 220 fixedly connected to one end of the guide sleeve 300.

[0040] In this embodiment, a hydraulic machine tool tailstock as described above is used. The driving component can drive the positioning component to move relative to the tailstock mounting base 100, thereby adjusting the relative position of the positioning gripper component 220 and the workpiece. The positioning gripper component 220 can clamp the workpiece. Especially for slender workpieces, the positioning gripper component 220 can apply radial clamping force to the workpiece to ensure the positioning stability of the workpiece. Through the cooperation between the positioning component and the workpiece positioning fixture (set on the machine tool, not shown in the figure, used to clamp and fix the workpiece), the workpiece can be fixed and positioned from both ends at the same time, effectively improving the machining accuracy and reducing the deformation of the workpiece during the machining process.

[0041] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the positioning assembly also includes a rotary hydraulic cylinder 210 that is fixedly connected to the guide sleeve 300.

[0042] The rotary hydraulic cylinder 210 is coupled to the positioning gripper assembly 220 and can drive the positioning gripper assembly 220 to rotate along its own axis and perform workpiece clamping.

[0043] In a preferred embodiment, a transmission component located within the guide sleeve 300 is provided between the rotary hydraulic cylinder 210 and the positioning gripper assembly 220.

[0044] In a preferred embodiment, such as Figure 2 As shown, the positioning gripper assembly 220 is specifically configured as a three-jaw chuck.

[0045] Similar to the chuck structure in traditional machine tool fixtures, the positioning gripper assembly 220 is driven by a rotary hydraulic cylinder 210. The gripper can hold the workpiece, thereby achieving the fixation and positioning of the workpiece.

[0046] It is understandable that the structure of the positioning gripper assembly 220 is not limited to the one mentioned above. For example, it can also be set as a five-jaw chuck or an external support clamping chuck, in which case it can externally support and clamp the tubular workpiece. As long as the positioning of the workpiece can be achieved, it will not be elaborated here.

[0047] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the drive assembly includes an adjusting cylinder 430 fixedly mounted on the tailstock mounting base 100. A drive rod 410 is fixedly mounted on the telescopic end of the adjusting cylinder 430. A connecting plate 420 fixedly connected to the guide sleeve 300 is fixedly mounted on the drive rod 410.

[0048] The extension and retraction direction of the regulating cylinder 430 is parallel to the central axis of the guide sleeve 300.

[0049] When the adjusting cylinder 430 drives the drive rod 410 to move, the drive rod 410 drives the guide sleeve 300 and the positioning component to move synchronously through the connecting plate 420, thereby realizing the position adjustment between the positioning component and the workpiece.

[0050] It is understandable that the configuration of the drive component is not limited to one type. For example, it can also be configured as a threaded screw structure or a gear rack structure, as long as it can achieve axial movement of the guide sleeve 300 relative to the tailstock mounting base 100. This will not be elaborated here.

[0051] In a preferred embodiment, such as Figure 3 , Figure 4 As shown, the tailstock mounting base 100 includes a base 110 and a guide hole 150 that passes through the base 110.

[0052] The guide sleeve 300 is slidably disposed within the guide hole 150, and the rotary hydraulic cylinder 210 and the positioning gripper assembly 220 are respectively disposed at both ends of the guide sleeve 300.

[0053] In a preferred embodiment, such as Figure 4 As shown, the seat 110 has a cavity 160, and the adjusting cylinder 430 is fixedly installed in the cavity 160.

[0054] In a preferred embodiment, such as Figure 4 As shown, a reinforcing plate 170 is fixedly installed inside the cavity 160, and mounting holes 180 are respectively provided on the inner wall of the reinforcing plate 170 and the side of the cavity 160 near the rotary hydraulic cylinder 210.

[0055] The regulating cylinder 430 is embedded in the mounting hole 180 and fixedly connected to the base 110.

[0056] In a preferred embodiment, such as Figure 3 , Figure 4 As shown, at least one fixing ear 120 is fixedly provided on the base 110, and at least one mounting hole 130 is provided through the fixing ear 120.

[0057] The tailstock mounting base 100 can be bolted to the external mounting platform through the mounting hole 130.

[0058] In a preferred embodiment, such as Figure 3 , Figure 4 As shown, two fixing ears 120 are fixedly provided on the base 110.

[0059] In the axial direction of the guide sleeve 300, two fixing ears 120 are located on opposite side end faces of the seat body 110.

[0060] In a preferred embodiment, such as Figure 3 , Figure 4 As shown, two mounting holes 130 are provided through the fixing lug 120.

[0061] The two mounting holes 130 are arranged at intervals in a reference direction, which is specifically the direction perpendicular to the central axis of the guide sleeve 300 on the horizontal plane.

[0062] In a preferred embodiment, such as Figure 3 , Figure 4 As shown, the bottom of the seat 110 is provided with a sliding groove 140.

[0063] The slide groove 140 is connected to the seat 110 in the reference direction.

[0064] Understandably, when the tailstock mounting base 100 is installed on the external mounting platform, the slide groove 140 can cooperate with the slider on the machine tool, that is, the tailstock mounting base 100 can move relative to the machine tool along the reference direction. At this time, the positioning component can move on the horizontal coordinate system, which further improves the flexibility of the hydraulic machine tool tailstock.
