Description

Technical Field

[0001] This utility model relates to the field of lathes, and in particular to an automatic feed lathe tailstock. Background Technology

[0002] The tailstock of an automatic feed lathe is an important component of the lathe, primarily used to support the workpiece in conjunction with the spindle center, ensuring the workpiece's coaxiality and stability during machining. It can also be used to mount tools such as drills and reamers for hole machining. Existing automatic feed lathe tailstocks typically include a tailstock body, a base, guideways, and a center. The tailstock body is fixedly connected to the base, which is slidably mounted on the guideways to adjust the overall position of the tailstock. The center is manually pushed to achieve feed or retraction operations.

[0003] However, existing manual feed and automatic feed lathe tailstocks have obvious drawbacks: on the one hand, when manually feeding the center, the operator needs to control the movement of the center by turning the handwheel or pushing the push rod, which is not only labor-intensive, but also difficult to accurately control the feed amount. Uneven operating force can easily lead to workpiece positioning deviation and affect machining accuracy; on the other hand, in batch processing or long-term processing scenarios, manual feeding efficiency is extremely low and cannot meet the needs of modern lathes for high-efficiency production. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic feed lathe tailstock, which can realize the rapid movement of the entire tailstock and the precise and automatic feeding of the tip, effectively improving the processing efficiency and automation level.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automatic feed lathe tailstock includes a tailstock body, a base, a guide rail, and a center. The tailstock body is fixedly connected to the base, and the base is slidably mounted on the guide rail. The lathe also includes a first drive assembly and a second drive assembly. The first drive assembly includes a lead screw nut, a first lead screw, a handwheel, and a thrust bearing. The second drive assembly includes a feed rod, a second lead screw, and a motor. The lead screw nut is fixedly mounted on the lathe bed and meshes with the first lead screw. The outer end of the first lead screw is fixedly connected to the handwheel, and the inner end of the first lead screw is connected to the center via the thrust bearing. The tailstock body is rotatably connected. The tailstock body has an axially extending cavity and an opening at the front end. The opening communicates with the cavity. The feed rod is slidably installed in the cavity. The feed rod has a center at its front end and a second lead screw at its rear end. The center extends from the opening to the outside of the tailstock body. The second lead screw is threadedly connected to the feed rod and driven by the motor. The motor drives the second lead screw to rotate and drives the feed rod and the center to move linearly through the threaded transmission, thereby realizing the feeding or retraction of the center.

[0007] Furthermore, the second drive assembly also includes a feed rod bushing and a center bushing. The center bushing is sleeved outside the center and located inside the cavity. The feed rod bushing is sleeved outside the feed rod and fixedly connected to the center bushing to prevent the feed rod from rotating synchronously with the second lead screw.

[0008] Furthermore, the automatic feed lathe tailstock also includes a locking component, which is installed at the bottom of the base and is used to lock the tailstock body, which has been adjusted in position, onto the guide rail.

[0009] Furthermore, the motor is a servo motor, which is electrically connected to the lathe's control system, enabling precise setting of the top feed speed and feed amount through the control system.

[0010] Furthermore, the tip and the front end of the feed rod are connected by a tapered surface, and the tip and the feed rod are fixed by a set screw, which facilitates the disassembly and replacement of the tip.

[0011] Compared to existing technologies, this utility model of an automatic feed lathe tailstock includes a tailstock body, a base, a guide rail, and a center. The tailstock body is fixedly connected to the base, and the base is slidably mounted on the guide rail. It also includes a first drive assembly and a second drive assembly. The first drive assembly includes a lead screw nut, a first lead screw, a handwheel, and a thrust bearing. The second drive assembly includes a feed rod, a second lead screw, and a motor. The lead screw nut is fixedly mounted on the lathe bed and meshes with the first lead screw. The outer end of the first lead screw is fixedly connected to the handwheel, and the inner end of the first lead screw is rotatably connected to the tailstock body via the thrust bearing. The tailstock body has an axially extending cavity and an opening at the front end, which communicates with the cavity. The feed rod is slidably mounted in the cavity. A center is located at the front end of the feed rod, and a second lead screw is located at the rear end. The center extends from the opening to the outside of the tailstock body. The second lead screw is threadedly connected to the feed rod and driven by the motor. The motor drives the second lead screw to rotate and, through threaded transmission, drives the feed rod and the center to perform linear motion, thereby achieving the feeding or retraction of the center.

[0012] This application achieves automatic feeding and retraction of the center point by setting up a motor, a second leadscrew, and a feed rod, eliminating the need for manual operation and significantly reducing labor intensity. Simultaneously, through the cooperation of the servo motor and control system, the feed speed and feed amount of the center point can be precisely controlled, effectively improving workpiece positioning accuracy and machining precision. Compared to traditional manual feeding methods, the automatic feeding structure of this invention significantly improves center point feeding efficiency, especially in batch processing scenarios, effectively shortening the processing cycle, increasing production efficiency, and meeting the needs of high-efficiency production in modern lathes.

[0018] 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.

[0019] Figures 1-2 The present invention relates to an automatic feed lathe tailstock, comprising a tailstock body 10, a base 20, a guide rail 30, a center point 40, a first drive assembly 50, and a second drive assembly 60.

[0020] In this embodiment:

[0021] The tailstock body 10 is fixedly connected to the base 20. The tailstock body 10 has a cavity extending along the axial direction and an opening at the front end. The opening communicates with the cavity. The diameter of the opening is slightly larger than the diameter of the tip 40 to ensure that the tip 40 can extend or retract smoothly.

[0022] The base 20 is slidably mounted on the guide rail 30.

[0023] The first drive assembly 50 includes a lead screw nut 51, a first lead screw 52, ​​a handwheel 53, and a thrust bearing 54.

[0024] The lead screw nut 51 is fixedly mounted on the bed by screws and meshes with the first lead screw 52. The outer end of the first lead screw 52 is fixedly connected to the handwheel 53 by a flat key. The inner end of the first lead screw 52 is rotatably connected to the tailstock body 10 by a thrust bearing 54. The thrust bearing 54 can withstand the axial thrust of the first lead screw 52 on the tailstock body 10, ensuring the stability of the first lead screw 52 when rotating.

[0025] The second drive assembly 60 includes a feed rod 61, a second lead screw 62, a motor 63, a feed rod bushing 64, and a center bushing 65.

[0026] The feed rod 61 is slidably installed in the cavity. The front end of the feed rod 61 is provided with a center 40 and the rear end is provided with a second lead screw 62. The center 40 extends from the opening to the outside of the tailstock body 10. The center 40 and the front end of the feed rod 61 are connected by a tapered surface. The center 40 and the feed rod 61 are fixed by a set screw, which facilitates the quick disassembly and replacement of center 40 of different specifications according to processing requirements, thereby improving the versatility and ease of use of the equipment.

[0027] The second lead screw 62 is threadedly connected to the feed rod 61 and is also connected to the motor 63. The motor 63 drives the second lead screw 62 to rotate, and through the threaded transmission, it drives the feed rod 61 and the center point 40 to make linear motion, thereby realizing the feeding or retraction of the center point 40. In this embodiment, the motor 63 is a servo motor 63, which is electrically connected to the lathe's control system, and can precisely set the feed speed and feed amount of the center point 40 through the control system.

[0028] The center bushing 65 is sleeved outside the center 40 and located inside the cavity. The feed rod bushing 64 is sleeved outside the feed rod 61 and fixedly connected to the center bushing 65 to prevent the feed rod 61 from rotating synchronously with the second lead screw 62.

[0029] The locking element 70 is installed at the bottom of the base 20 to lock the tailstock body 10, which has been adjusted in position, onto the guide rail 30 to prevent the tailstock body 10 from shifting during processing.

[0030] The working process for this application is as follows:

[0031] The operator first turns the handwheel 53, which drives the first lead screw 52 to rotate. Since the lead screw nut 51 is fixed to the machine bed, the first lead screw 52 pushes the tailstock body 10 and the base 20 to slide along the guide rail 30 under the meshing action, completing the overall rough adjustment of the tailstock position. Then, the feed speed and feed amount of the center point 40 are set through the lathe control system, and the servo motor 63 is started. The servo motor 63 drives the second lead screw 62 to rotate. The second lead screw 62 drives the feed rod 61 to move axially along the cavity through meshing with the internal thread hole, thereby pushing the center point 40 to press against the workpiece. After the machining is completed, the servo motor 63 rotates in the opposite direction, driving the center point 40 to retract.

[0032] This application achieves automatic feeding and retraction of the center point 40 by setting up a motor 63, a second lead screw 62, and a feed rod 61, eliminating the need for operators to manually push the center point 40, thus significantly reducing labor intensity. At the same time, through the cooperation of the servo motor 63 and the control system, the feed speed and feed amount of the center point 40 can be precisely controlled, effectively improving workpiece positioning accuracy and machining accuracy. Compared with the traditional manual feeding method, the automatic feeding structure of this utility model can significantly improve the feeding efficiency of the center point 40, especially in batch processing scenarios, which can effectively shorten the processing cycle, improve production efficiency, and meet the needs of high-efficiency production of modern lathes.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
