Description

Technical Field

[0001] This utility model belongs to the field of worm gear processing technology, specifically relating to a quick-change annular envelope worm gear processing machine tool. Background Technology

[0002] Currently, the machining of annular envelope worm gears mainly relies on dedicated CNC machine tools or precision-modified general-purpose machine tools. The machining process typically involves multiple steps, including roughing, semi-finishing, and finishing. Due to the complex tooth profile and extremely high precision requirements of the worm gear, each step often requires the use of cutting tools of different specifications, shapes, or materials.

[0003] A search revealed Chinese patent CN222643414U, which discloses a worm gear toroidal finishing machine tool, including an operating table, a machining table on the operating table, and a grinding mechanism on the operating table next to the machining table; however, existing machine tools require tool resetting every time the tool is changed, resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change annular envelope worm gear machining machine tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-change annular envelope worm gear machining machine tool, including a lathe tool post, a tool placement groove is provided inside the lathe tool post, a lathe tool body is disposed inside the tool placement groove, a fixed shell is fixedly connected to the surface of the lathe tool post by bolts, a length limiting plate is disposed inside the fixed shell, a force application block is fixedly connected to the surface of the length limiting plate, a pointer is fixedly connected to the surface of the force application block located outside the fixed shell, a ruler plate is disposed on one side of the fixed shell located on the pointer, a limiting mechanism for locking the length limiting plate is disposed on the top surface of the fixed shell, and a display mechanism is disposed at one end of the length limiting plate.

[0008] Preferably, a rubber block is fixedly connected to one end of the positioning rod inserted into the limiting groove, and the rubber block is in close contact with the fixing shell.

[0009] Preferably, a first guide rod is slidably connected to the surface of the linkage plate, the first guide rod passes through the surface of the linkage plate and is fixedly connected to the force-applying block.

[0010] Preferably, the display mechanism includes a positioning frame fixedly connected to the end of the length limiting plate away from the force application block. The positioning frame has a U-shaped structure, with a light emitter installed on the inner bottom surface of the positioning frame and a light receiver installed on the inner top surface of the positioning frame. The light emitter and the light receiver are on the same axis.

This eliminates the tedious process of repeatedly measuring, test cutting and calibrating each tool in the traditional method, greatly shortening the tool change and initial tool setting time and improving the machine tool processing efficiency.

[0015] 2. This utility model integrates an infrared light sensor transmitter and a light sensor receiver within an U-shaped positioning frame at the end of the length limiting plate. This photoelectric positioning mechanism provides the operator with clear and real-time auditory feedback, accurately indicating that the blade tip has reached the target position coaxial with the end of the length limiting plate, effectively avoiding errors from human visual judgment and ensuring the repeatability and positioning accuracy of the blade installation.

[0016] 3. This utility model drives the positioning plate to slide along the second guide rod by tightening the second bolt. This structural design effectively compensates for the risk of slight tool deviation or loosening that may occur when clamping in one direction, so that the cutting tool remains stable during the machining process and ensures that the tool tip position is strictly consistent with the preset calibration position, thereby ensuring the machining accuracy of the final circumferential worm gear.

[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a quick-change annular envelope worm gear machining machine tool, including a lathe tool post 1. The lathe tool post 1 has a tool placement groove 2 inside, and a cutting tool body 3 is placed inside the tool placement groove 2. A fixed shell 4 is bolted to the surface of the lathe tool post 1. A length limiting plate 5 is installed inside the fixed shell 4. A force application block 8 is fixedly connected to the surface of the length limiting plate 5. A pointer 12 is fixedly connected to the surface of the force application block 8 located on the outer side of the fixed shell 4. A ruler plate 9 is provided on one side of the fixed shell 4 near the pointer 12. A limiting mechanism for locking the length limiting plate 5 is provided on the top surface of the fixed shell 4. A display mechanism is provided at one end of the plate 5. When installing the cutting tool body 3, the cutting tool body 3 is placed inside the tool placement groove 2, and then force is applied to the force block 8 to make the length limiting plate 5 slide inside the fixed shell 4. Then, the length of the cutting tool body 3 is determined by observing the distance the pointer 12 moves on the surface of the ruler plate 9. When the length limiting plate 5 moves to the appropriate length, the length limiting plate 5 is positioned by the limiting mechanism. Then the cutting tool body 3 can be moved so that the tip of the cutting tool body 3 is on the same axis as one end of the length limiting plate 5. This achieves quick tool loading without the need for calibration of each tool, making it more efficient.

[0025] In this embodiment, both ends of the fixed shell 4 are interconnected, and the fixed shell 4 is located below the cutting tool body 3. The two ends of the fixed shell 4 are interconnected to prevent debris from entering the interior of the fixed shell 4 during processing and being difficult to discharge, thereby affecting the accuracy.

[0026] In this embodiment, the limiting mechanism includes a limiting groove formed on the top surface of the fixed shell 4, and a positioning rod 13 is provided inside the limiting groove. The positioning rod 13 is slidably connected to the fixed shell 4 through the limiting groove. A linkage plate 15 is fixedly connected to the top of the positioning rod 13. A first bolt 14 is threadedly connected to the end of the linkage plate 15 away from the positioning rod 13. The first bolt 14 passes through the linkage plate 15 and is threadedly connected to the force application block 8. A rubber block is fixedly connected to the end of the positioning rod 13 inserted into the limiting groove, and the rubber block is in close contact with the fixed shell 4. When it is necessary to limit the length limiting plate 5, the first bolt 14 is rotated, and the linkage plate 15 threadedly connected to the first bolt 14 will drive the positioning rod 13 to insert into the interior of the limiting groove. Through the tight contact between the rubber block and the fixed shell 4, the friction force is used to limit the length limiting plate 5.

[0027] In this embodiment, a first guide rod 16 is slidably connected to the surface of the linkage plate 15. The first guide rod 16 passes through the surface of the linkage plate 15 and is fixedly connected to the force application block 8. When the first bolt 14 is rotated, the linkage plate 15 is limited by the first guide rod 16 to prevent it from rotating.

[0028] In this embodiment, the display mechanism includes a positioning frame 6 fixedly connected to the end of the length limiting plate 5 away from the force application block 8. The positioning frame 6 has a U-shaped structure. A light sensor 7 is installed on the inner bottom surface of the positioning frame 6, and a light sensor receiver 10 is installed on the inner top surface of the positioning frame 6. The light sensor 7 and the light sensor receiver 10 are on the same axis. A buzzer 11 is installed on the top surface of the positioning frame 6. The buzzer 11 is electrically connected to the light sensor receiver 10. When the cutting tool body 3 is installed, the light sensor 7 is connected to the power supply and then started. The light sensor 7 will emit infrared light upwards, which will then be received by the light sensor receiver 10. When the tip of the cutting tool body 3 moves to block the light, the light sensor receiver 10 will activate the buzzer 11, which will sound an alarm to remind the operator that the tool has moved to the appropriate position.

[0029] It should be noted that the light sensor emitter 7 consists of a laser diode, a driving circuit, an optical lens, and a housing, etc., and converts electrical signals into light signals of a specific wavelength. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0030] The light receiver 10 includes a photosensitive element, a signal processing circuit, optical components, and an output interface. It receives light signals emitted by the transmitter or ambient reflected light and converts them into electrical signals. Those skilled in the art can configure it according to actual needs, which will not be elaborated here.

[0031] In this embodiment, a second guide rod 19 is fixedly connected to the surface of the lathe tool post 1, a positioning plate 17 is slidably connected to the surface of the second guide rod 19, a second bolt 18 is threadedly connected to the surface of the positioning plate 17, and the second bolt 18 is threadedly connected to the lathe tool post 1. A pressing block 20 is fixedly connected to the side of the positioning plate 17 facing the tool body 3. After the tool body 3 is calibrated, force is applied to the second bolt 18 to move the positioning plate 17 on the surface of the second guide rod 19. The pressing block 20 then applies lateral pressure to the tool body 3 to prevent the tool body 3 from tilting during vertical pressure, thereby making the tip of the tool body 3 different from the calibration position.

[0032] The use of this utility model involves the following steps:

[0033] S1: When installing the cutting tool body 3, place the cutting tool body 3 into the tool placement groove 2, and then apply force to the force application block 8 to make the length limiting plate 5 slide inside the fixed shell 4. Then, observe the distance the pointer 12 moves on the surface of the ruler plate 9 to determine the extension length of the cutting tool body 3. When the length limiting plate 5 moves to the appropriate length, the length limiting plate 5 is positioned by the limiting mechanism. Then the cutting tool body 3 can be moved so that the tip of the cutting tool body 3 and one end of the length limiting plate 5 are on the same axis. This achieves quick tool loading without the need for calibration of each tool, making it more efficient.

[0034] S2: When it is necessary to limit the length limiting plate 5, rotate the first bolt 14, and the linkage plate 15 threadedly connected to the first bolt 14 will drive the positioning rod 13 to insert into the inside of the limiting groove. Through the tight fit between the rubber block and the fixed shell 4, the friction force is used to limit the length limiting plate 5.

[0035] S3: When installing the cutting tool body 3, connect the light sensor 7 to the power supply and start it. The light sensor 7 will emit infrared light upwards, which will then be received by the light sensor receiver 10. When the tip of the cutting tool body 3 moves to block the light, the light sensor receiver 10 will activate the buzzer 11, which will sound an alarm to remind the operator that the tool has been moved to the appropriate position.

[0036] S4: After the tool body 3 is calibrated, force is applied to the second bolt 18 to move the positioning plate 17 on the surface of the second guide rod 19. The tool body 3 is then subjected to lateral compression by the compression block 20 to prevent the tool body 3 from tilting during vertical compression, thus making the tip of the tool body 3 different from the calibration position.

[0037] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0038] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
