Technical Field
[0001] This utility model relates to the field of servo tool post technology for CNC automatic lathes, and particularly to a radial feed structure for a servo tool post of a CNC automatic lathe. Background Technology
[0002] A cam-type automatic lathe is an automatic machining tool that controls the machining program through a cam mechanism. It is mainly used in the mass production of precision small parts in the instrument, watch, automobile and electronics industries.
[0003] Existing general-purpose cam-driven automatic lathes with tool post slides mainly rely on cams to drive levers to swing and screw semicircular contacts to drive the tool post to achieve radial feed and linear movement, thus fulfilling the functional requirements of machining the outer diameter of parts. However, in this structure, when the screw semicircular contacts drive the tool post to achieve radial feed and linear movement, the semicircular contacts and the end face of the tool post experience sliding hard friction. High-frequency and long-term operation will wear down the surface, leading to changes in the machining dimensions and affecting the stability of the machining dimensions. Utility Model Content
[0004] The main objective of this invention is to provide a radial feed structure for a servo tool post of a CNC automatic lathe, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A radial feed structure for a servo tool post of a CNC automatic lathe includes a right-angle reversing connector. A servo motor is fixedly connected to one side of the right-angle reversing connector. A tool post dovetail support is fixedly connected to the lower surface of the right-angle reversing connector. A ball screw is fixedly connected to the output end of the right-angle reversing connector. A tool box dovetail slide is slidably connected to the inner wall of the tool post dovetail support. A tool post radial positioning pin is fixedly connected to one side of the tool box dovetail slide. A tool post longitudinal positioning stud is fixedly connected to one side of the tool box dovetail slide.
[0006] In order to achieve the effect of radial machining of the workpiece, as a radial feed structure of the servo tool post of the CNC automatic lathe of this utility model, a tool holder is provided on the other side of the dovetail slide of the tool box, and a lathe tool is fixedly connected to one side of the tool holder.
[0007] In order to provide power to the radial feed structure, the right-angle reversing connector and the servo motor are fixed together by bolts as a radial feed structure of the servo tool post of the CNC automatic lathe of this utility model.
[0008] In order to achieve the effect of vertical power conversion and transmission, the right-angle reversing connector and the dovetail support of the tool post are fixed together by bolts as a radial feed structure of the servo tool post of the CNC automatic lathe of this utility model.
[0009] Compared with the prior art, the present invention has the following beneficial effects: The radial feed structure of the servo tool post of this CNC automatic lathe is achieved through the setting of a right-angle reversing connector, a servo motor, a tool post dovetail support, a ball screw, a tool box dovetail slide, a tool post radial positioning pin, and a tool post longitudinal positioning stud. A servo motor mounting bracket is added to the tool box, the servo motor is horizontally mounted, and the servo motor is connected and fixed to the right-angle reversing connector. The servo motor is also connected to the tool post lead screw through the right-angle reversing connector, so that the tool post can achieve servo-driven radial feed and complete the functional requirements of external diameter cutting of the part.

[0012] 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.
[0013] Example 1 like Figure 1-5As shown, a radial feed structure for a servo tool post of a CNC automatic lathe includes a right-angle reversing connector 1, a servo motor 2 fixedly connected to one side of the right-angle reversing connector 1, a tool post dovetail support 3 fixedly connected to the lower surface of the right-angle reversing connector 1, a ball screw 4 fixedly connected to the output end of the right-angle reversing connector 1, a tool box dovetail slide 5 slidably connected to the inner wall of the tool post dovetail support 3, a tool post radial positioning pin 6 fixedly connected to one side of the tool box dovetail slide 5, and a tool post positioning longitudinal stud 7 fixedly connected to one side of the tool box dovetail slide 5.
[0014] In practical use, the tool holder is equipped with a right-angle reversing connector 1, a servo motor 2, a tool post dovetail support 3, a ball screw 4, a tool box dovetail slide 5, a tool post radial positioning pin 6, and a tool post positioning longitudinal stud 7. A mounting bracket for the servo motor 2 is added to the tool box, and the servo motor 2 is horizontally mounted. The servo motor 2 is connected and fixed to the right-angle reversing connector 1, and connected to the tool post screw via the right-angle reversing connector 1. This enables the tool post to achieve servo-driven radial feed, fulfilling the functional requirements of external diameter cutting of parts. During use, the servo motor 2 is started, and under the action of the right-angle reversing connector 1, the power is transferred to the ball screw 4, causing the tool box dovetail slide 5 in the tool post dovetail support 3 to move downwards, driving the cutting tool 9 downwards to perform radial cutting on the workpiece. The tool post positioning longitudinal stud 7 allows for longitudinal adjustment of the tool, enabling radial cutting at different positions. This upgrades the radial cutting feed of the tool post from a mechanical cam lever drive to a CNC servo motor 2 drive, improving the cutting feed response speed and feed accuracy.
[0015] In this embodiment, a tool holder 8 is provided on the other side of the tool box dovetail slide 5, and a lathe tool 9 is fixedly connected to one side of the tool holder 8.
[0016] In practical use, the workpiece is radially machined by setting the cutting tool 9.
[0017] In this embodiment, the right-angle reversing connector 1 and the servo motor 2 are fixed together by bolts.
[0018] In practical use, the servo motor 2 is used to provide power to the radial feed structure.
[0019] In this embodiment, the right-angle reversing connector 1 and the tool holder dovetail support 3 are fixed together by bolts.
[0020] In practical use, the power is vertically converted and transmitted through the right-angle reversing connector 1.
[0021] Working principle: When in use, the servo motor 2 is started, and under the action of the right angle reversing connector 1, the power is converted and transmitted to the ball screw 4, so that the tool box dovetail slide 5 in the tool holder dovetail support 3 moves downward, driving the cutting tool 9 to move downward to perform radial cutting on the workpiece. The tool holder positioning longitudinal stud 7 can adjust the tool longitudinally to perform radial cutting at different positions.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
