[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. The basic components of a CNC machine tool include a machining program carrier, a CNC device, a servo drive device, the machine tool body, and other auxiliary devices. The machine tool body generally also includes a tailstock for fixing the workpiece.

[0003] In existing technology, the tailstock is fixed to the top of the mounting base, and the mounting base is moved by a hydraulic rod, so that the ejector pin is pressed against the workpiece to fix the workpiece.

[0004] Traditional tailstocks are generally controlled by handwheels, and the entire positioning and clamping process requires manual operation, which is time-consuming and labor-intensive, increasing the workload of workers. When dealing with larger objects, multiple people are needed to clamp and position them. The use of manual tailstocks increases the workload and reduces work efficiency. Utility Model Content

[0020] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Traditional tailstocks are generally controlled by handwheels, and the entire positioning and clamping process requires manual operation, which is time-consuming and labor-intensive, increasing the workload of workers. When dealing with larger objects, multiple people are needed to clamp and position them. The use of manual tailstocks increases the workload and reduces work efficiency.

[0022] In view of this, the present invention provides a tailstock structure for a CNC horizontal lathe, which solves the problem that traditional tailstocks are generally controlled by handwheels, and the entire positioning and clamping process requires manual operation, which is time-consuming and labor-intensive, increases the workload of workers, and requires multiple people to clamp and position larger objects. The use of manual tailstocks increases the workload and reduces work efficiency.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1-5 As can be seen, a tailstock structure for a CNC horizontal lathe includes a base 1, with a center pin 11 installed at one end of the base 1. The model of the base 1 is not limited, as long as it meets the actual use requirements. This technology is well known to those skilled in the art, so it will not be described in detail. A fixing frame 12 is fixedly connected to the bottom of the base 1, and a mounting seat 14 is installed at the bottom of the fixing frame 12. A slide rail 15 is movably connected to the inner wall of the mounting seat 14. A groove corresponding to the slide rail 15 is opened at the bottom of the mounting seat 14 to ensure that the mounting seat 14 can move on the outer wall of the slide rail 15. A fixing structure 2 is installed on the top of the slide rail 15. The fixing structure 2 includes: a servo motor 21, fixedly connected to the outer wall of the mounting seat 14; and a bidirectional lead screw 22, which is rotatably connected to the inner wall of the mounting seat 14 through a bearing, and one end of which extends to the outside of the mounting seat 14 is fixed. The system consists of: a top block 23 connected to the output end of the servo motor 21; a top block 23 threadedly connected to the outer wall of the bidirectional lead screw 22 and slidably engaged with the inner wall of the mounting base 14; a limit block 24 pressed against the bottom of the top block 23 and movably connected to the inner wall of the mounting base 14; a mounting rod 25 fixedly connected to the bottom of the limit block 24 and inserted into the inner wall of the mounting base 14; and a fixing block 26 fixedly connected to the bottom of the mounting rod 25 and inserted into the inner wall of the mounting base 14, positioned above the slide rail 15. Through the cooperation of the servo motor 21 and the bidirectional lead screw 22, the top block 23 presses against the limit block 24, and the mounting rod 25 drives the fixing block 26 to press against the top of the slide rail 15. The model of the servo motor 21 is not limited, as long as it meets the actual usage requirements, and an external controller controls the rotation of the servo motor 21.

[0025] In the specific implementation process, it is worth noting that the bottom of the top block 23 is set in a slope shape, and its slope surface contacts the outer wall of the limiting block 24. When the top block 23 presses against the limiting block 24, the mounting rod 25 can drive the fixing block 26 to move and press against the top of the slide rail 15 to fix it. Moreover, the bottom of the fixing block 26 is provided with a wear-resistant layer, which can increase the resistance when it contacts the slide rail 15, thereby fixing the mounting seat 14.

[0026] Furthermore, a return spring 4 is sleeved on the outer wall of the mounting rod 25, and the return spring 4 abuts against the limit block 24 and the mounting base 14;

[0027] In the specific implementation process, it is worth noting that by using the return spring 4 to squeeze the limit block 24, the pressure on the top of the limit block 24 is eliminated, causing the mounting rod 25 to drive the fixed block 26 to rise and separate from the slide rail 15, so that the mounting seat 14 can move normally.

[0028] Furthermore, a limiting plate 16 is provided above the top of the top block 23, and the bottom of the limiting plate 16 is fixedly connected to the top of the mounting base 14 by bolts.

[0029] In the specific implementation process, it is worth noting that the top block 23 is wrapped with the limiting plate 16. When a fault occurs between the top block 23 and the bidirectional lead screw 22, the limiting plate 16 can be removed and its interior can be inspected.

[0030] Specifically, when using the tailstock structure of this CNC horizontal lathe, when fixing the workpiece, push the mounting seat 14 to move it on the outer wall of the slide rail 15, and press the ejector pin 11 against the outer wall of the workpiece. During fixing, the operator can control the servo motor 21 to rotate through the external controller, which drives the bidirectional lead screw 22 to rotate and connect it with the top block 23. The top block 23 will move inside the mounting seat 14 and press the limit block 24, causing the mounting rod 25 to drive the fixing block 26 to press against the top of the slide rail 15, thus fixing the mounting seat 14 and improving the operator's work efficiency. When releasing the workpiece, use the controller to control the servo motor 21 to rotate in the opposite direction, causing the top block 23 to separate from the limit block 24. Under the pressure of the return spring 4, the limit block 24 drives the mounting rod 25 and the fixing block 26 to move, separating the fixing block 26 from the slide rail 15, thereby separating the ejector pin 11 from the workpiece. The top block 23 and the bidirectional lead screw 22 can be inspected by disassembling the limit plate 16.

[0031] Example 2: From Figure 1-5 It can be seen that the bottom of the fixed frame 12 is fixedly connected to the mounting plate 13, the bottom of the mounting plate 13 is fixedly connected to the top of the limiting plate 16 by bolts, and a limiting device 3 is installed between the mounting plate 13 and the limiting plate 16.

[0032] In the specific implementation process, it is worth noting that the base 1 is fixed to the top of the mounting base 14 using the mounting plate 13, so that the mounting base 14 drives the base 1 to move.

[0033] Furthermore, the limiting device 3 includes: an insert block 31, which is fixedly connected to the top of the limiting plate 16 and inserted into the bottom of the mounting plate 13; and a fixing cover plate 32, which is fixedly connected to the top of the insert block 31 through the top opening of the mounting plate 13 and abuts against the top of the mounting plate 13; wherein, the cooperation between the insert block 31 and the fixing cover plate 32 facilitates the installation of the mounting plate 13 and the limiting plate 16.

[0034] In the specific implementation process, it is worth noting that the insert 31 is passed through the mounting plate 13, and after passing through, the fixing cover 32 is pressed against the top of the mounting plate 13, and the fixing cover 32 is fixed to the top of the limiting plate 16 with bolts, and the mounting plate 13 is pressed against it.

[0035] Specifically, based on the above embodiments, when installing the base 1 and the mounting base 14, the insert 31 at the top of the limiting plate 16 is inserted into the interior of the mounting plate 13, and the fixing cover 32 is pressed against the top of the mounting plate 13. After pressing, the fixing cover 32 is fixed to the top of the limiting plate 16 with bolts, which makes it convenient to install fixing bolts between the mounting plate 13 and the limiting plate 16.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
