Description

Technical Field

[0001] This utility model relates to the field of lathe technology, and more specifically, to a lathe tool post fine-tuning structure. Background Technology

[0002] A lathe is a machine tool that primarily uses a cutting tool to machine rotating workpieces. It consists of a bed, headstock, feed box, and apron. Lathes are characterized by high machining accuracy and strong adaptability, and are widely used in many fields such as machinery manufacturing, automobiles, and shipbuilding. They are an indispensable piece of equipment in manufacturing, capable of processing various metal materials into parts of various shapes, providing fundamental support for industrial production.

[0003] Lathe cutting tools wear down over time, causing a slight shortening in length. Currently, lathe tool turrets are primarily adjusted in the height direction, making length adjustment inconvenient. Furthermore, the tool turret's travel distance during lathe operation is set based on the overall dimensions of the workpiece and the machining process, making adjustment via the feed mechanism difficult. As the tool wears and shortens, the relative position between the tool and workpiece changes during cutting, leading to dimensional deviations and affecting machining accuracy. Therefore, we propose a lathe tool turret fine-tuning structure. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a lathe tool post fine-tuning structure to solve the technical problem that the current tool post is inconvenient to fine-tune the tool, and the relative position of the tool and the workpiece changes during the cutting process after the tool wears and shortens, resulting in deviations in the machining dimensions.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lathe tool post fine-tuning structure, including a mounting mechanism and a fine-tuning mechanism disposed within the mounting mechanism. The mounting mechanism includes a housing, and the fine-tuning mechanism includes a threaded rod rotatably mounted within the housing. An adjusting handle connected to the axis of the threaded rod is rotatably mounted on the upper end of the housing. An adjusting seat is threadedly mounted on the threaded rod. A triangular protrusion is provided on the side end of the adjusting seat. An adjusting block is provided on the triangular protrusion. A connecting rod is provided at the front end of the adjusting block. An adjusting opening is provided on the outer surface of the housing. The connecting rod extends out of the housing from the adjusting opening. A tool holder is mounted at the end of the connecting rod. A bolt is provided on the tool holder, and a tool is mounted on the tool holder by the bolt.

[0006] Preferably, the lower end of the housing is provided with a mounting base, the mounting base is provided with mounting holes, and the side end of the housing is provided with dimension markings.

[0007] Preferably, positioning rods are symmetrically installed inside the housing, and positioning holes are symmetrically opened on the adjusting seat, with the positioning rods located inside the positioning holes.

[0008] Preferably, the triangular protrusion is triangular in shape, and a hollow groove is formed on the triangular protrusion. The hollow groove is obliquely oriented, and the hollow groove forms a limiting rod and an inclined surface on the side end of the triangular protrusion. The adjusting block is sleeved on the limiting rod, and one end of the adjusting block is inclined, with the inclined surface of the adjusting block fitting against the inclined surface of the triangular protrusion.

[0009] Preferably, a pointer is mounted on the upper end of the tool holder, the pointer is L-shaped, and the end of the pointer points to the beginning of the dimension mark.

[0010] Preferably, the rear end of the blade holder is symmetrically provided with limiting sliders, and the outer surface of the housing is provided with a limiting groove corresponding to the position of the limiting slider, and the limiting slider is slidably installed in the limiting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of an adjustment seat structure, uses a hollowed-out groove on the triangular protrusion to form a limiting rod and a slope. This not only limits the adjustment block but also squeezes the adjustment block when the triangular protrusion descends, causing it to move laterally. This allows for a stable change in the position of the adjustment block, thereby adjusting the position of the cutting tool. When the cutting tool wears and shortens, this fine-tuning structure can promptly adjust the relative position between the cutting tool and the workpiece, preventing deviations in machining dimensions due to changes in the cutting tool's position. This ensures the machining accuracy of the workpiece and solves the problem that current tool holders are inconvenient for fine-tuning the cutting tool, and that changes in the relative position between the cutting tool and the workpiece during cutting due to tool wear and shortening lead to deviations in machining dimensions.

[0013] 2. This utility model also incorporates a pointer and dimension mark structure. The L-shaped pointer mounted on the upper end of the tool holder cooperates with the dimension mark on the side of the housing. When adjusting the tool, the operator can accurately determine the length of the tool's forward movement by observing the position of the pointer pointing to the dimension mark, which facilitates the fine-tuning operation of the tool and improves the efficiency and accuracy of fine-tuning.

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a lathe tool post fine-tuning structure, including a mounting mechanism 100 and a fine-tuning mechanism 200 disposed within the mounting mechanism 100. The mounting mechanism 100 includes a housing 101. The fine-tuning mechanism 200 includes a threaded rod 201 rotatably mounted within the housing 101. An adjusting handle 202 rotatably mounted on the upper end of the housing 101 is connected to the axis of the threaded rod 201. An adjusting seat 204 is threaded onto the threaded rod 201. A triangular protrusion 2042 is provided on the side end of the adjusting seat 204. An adjusting block 205 is provided on the triangular protrusion 2042. A connecting rod is provided at the front end of the adjusting block 205. An adjusting port 104 is opened on the outer surface of the housing 101. The connecting rod extends out of the housing 101 from the adjusting port. A tool holder 206 is installed at the end of the connecting rod. A bolt 2061 is provided on the tool holder 206. A cutting tool 207 is installed on the tool holder 206 by means of the bolt 2061. This invention can stably and accurately adjust the position of the tool 207. When the tool 207 is worn and shortened, the relative position of the tool 207 and the workpiece can be adjusted in time through this fine-tuning structure to avoid deviation in the machining dimensions caused by changes in the position of the tool 207, thus ensuring the machining accuracy of the workpiece.

[0022] Specifically, a mounting base 102 is provided at the lower end of the housing 101, and a mounting hole is provided on the mounting base 102. Dimension markings 103 are provided on the side of the housing 101. The present invention can be installed on the feed mechanism of a lathe via the mounting base 102.

[0023] Furthermore, positioning rods 203 are symmetrically installed inside the housing 101, and positioning holes 2041 are symmetrically opened on the adjusting seat 204, with the positioning rods 203 located inside the positioning holes 2041. The positioning rods 203 can limit the adjusting seat 204, ensuring the stability of the adjusting seat 204 during descent and ascent, and preventing the adjusting seat 204 from rotating.

[0024] It is worth noting that the triangular protrusion 2042 is triangular in shape, and a hollow groove 2043 is formed on the triangular protrusion 2042. The hollow groove 2043 is angled, and the side end of the triangular protrusion 2042 forms a limiting rod 2044 and an inclined surface. The adjusting block 205 is sleeved on the limiting rod 2044, and one end of the adjusting block 205 is angled, which fits against the inclined surface of the triangular protrusion 2042. The limiting rod 2044 formed by the hollow groove 2043 can limit the adjusting block 205 and prevent it from moving freely. In conjunction with the inclined surface of the triangular protrusion 2042, the position of the adjusting block 205 can be changed, thereby allowing for fine adjustment of the tool 207.

[0025] It is worth mentioning that a pointer 2062 is installed on the upper end of the tool holder 206. The pointer 2062 is L-shaped, and its end points to the beginning of the dimension mark 103. When adjusting the tool 207, the tool 207 is moved forward according to its wear length. During the movement, the pointer 2062 will change position. By observing the position of the pointer 2062 pointing to the dimension mark 103, the length of forward movement of the tool 207 can be determined, which facilitates fine-tuning of the tool 207.

[0026] It is worth noting that the tool holder 206 has symmetrically arranged limit sliders 2063 at its rear end, and the outer surface of the housing 101 has a limit groove 105 corresponding to the position of the limit slider 2063. The limit slider 2063 is slidably installed in the limit groove 105. The setting of the limit slider 2063 and the limit groove 105 can limit the tool holder 206, so that the tool holder 206 can move along the limit groove 105 when the tool 207 is finely adjusted, which can prevent the position of the tool 207 from being deviated.

[0027] Working Principle: This embodiment provides a lathe tool post fine-tuning structure. In use, the invention is first installed on the lathe's feed mechanism through the mounting holes on the mounting base 102, providing the basic installation conditions for subsequent work. When the lathe tool 207 wears down after prolonged use, resulting in a shortened length, fine-tuning of the tool 207 is required. The operator rotates the adjusting handle 202. Since the adjusting handle 202 is axially connected to the threaded rod 201, the rotation of the adjusting handle 202 will cause the threaded rod 201 to rotate within the housing 101. When the threaded rod 201 rotates, the adjusting seat 204, which is threadedly mounted to it, will descend along the axial direction of the threaded rod 201. During this process, the symmetrically opened positioning holes 2041 on the adjusting seat 204 cooperate with the symmetrically installed positioning rods 203 inside the housing 101. The positioning rods 203 are located inside the positioning holes 2041, limiting the adjusting seat 204 and ensuring that the adjusting seat 204 can only move smoothly along the axial direction of the threaded rod 201, preventing the adjusting seat 204 from rotating and ensuring the stability of the adjustment. As the adjusting seat 204 moves downward, the triangular protrusion 2042 on its side end also descends. The inclined surface of the triangular protrusion 2042 will press against the adjusting block 205. The limiting rod 2044 limits the adjusting block 205. Because the vertical position of the adjusting block 205 is fixed, the adjusting block 205 will move laterally. The movement of the adjusting block 205 causes the tool holder 206 to move, which in turn moves the tool 207 mounted on the tool holder 206. During the movement of the tool 207, the limiting sliders 2063 symmetrically arranged at the rear end of the tool holder 206 slide within the corresponding limiting grooves 105 on the outer surface of the housing 101, limiting the tool holder 206 and ensuring that the tool 207 can only move along the direction of the limiting grooves 105, preventing the tool 207 from shifting position during fine-tuning. Simultaneously, the L-shaped pointer 2062 mounted on the upper end of the tool holder 206 points to the dimension mark 103 on the side of the housing 101, allowing the operator to adjust the tool 207 according to its wear length. Tool 207 moves forward. During the movement, pointer 2062 changes position. By observing the position of pointer 2062 pointing to dimension mark 103, the length of forward movement of tool 207 can be accurately determined, thereby achieving precise fine-tuning of tool 207. This ensures that after tool 207 wears and shortens, the relative position of tool 207 and workpiece can be restored to a suitable state, avoiding deviations in machining dimensions due to changes in tool 207 position and ensuring machining accuracy. Each time tool 207 is fine-tuned, the positions of four tools 207 can be adjusted. When tools 207 in other directions are moved, the fine-tuning mechanism 200 can be used to adjust the other tools 207 back to their original positions.
