[0002] A machine tool is a device used to manufacture machine parts, also known as a machine tool; it uses cutting tools to perform cutting, grinding, drilling, boring, tapping and other processing operations on metal or other materials to precisely process raw materials into parts with specific shapes, sizes and precision requirements.

[0003] Existing machine tools generally adopt two feeding methods: manual and automatic. Automatic feeding mainly relies on conveyor belts to transport materials to the machine tool. Compared with manual feeding, conveyor belts, with their continuous and stable conveying characteristics, can deliver materials to the processing position at a faster speed, thereby significantly improving the processing efficiency of the machine tool.

[0004] However, because the conveyor belt lacks the function of positioning the material above during the automatic feeding process, the material is very easy to shift in position due to the movement of the conveyor belt during the transmission process; this shift will not only affect the accurate feeding of the material, but also bring many inconveniences to the subsequent machine tool processing. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5A machine tool loading structure for easy positioning includes a loading rack 1, a conveyor belt 2 fixedly installed inside the loading rack 1, and a positioning assembly 3 on the top of the loading rack 1. The positioning assembly 3 includes a support frame 301, a partition plate 302, an electric push rod 303, a blocking bar 304, a moving groove 305, a limiting strip 306, a moving slide 307, an electric push rod 308, a positioning plate 309, and a V-shaped positioning groove 310. The support frame 301 is fixedly connected to the top of the loading rack 1 in a parallel arrangement, the partition plate 302 is fixedly connected to the bottom of the support frame 301 in a parallel arrangement and located above the conveyor belt 2, and the electric push rod 303 is fixedly... Installed on the top of support frame 301, the barrier bar 304 is fixedly installed on the telescopic end of electric push rod 303, the moving groove 305 is opened on the top of the feeding rack 1 and is located in front of support frame 301, the limiting strip 306 is fixedly connected to the inside of the moving groove 305, the moving slide 307 is opened in the inside of the limiting strip 306, the electric push rod 308 is fixedly installed in the inside of the moving groove 305 and is located in front of the limiting strip 306, the positioning plate 309 is slidably installed in the inside of the moving slide 307 and is located above the conveyor belt 2, and the V-shaped positioning grooves 310 are distributed in parallel on the side of the positioning plate 309 near support frame 301.

[0025] The partition plate 302 separates materials to prevent overcrowding during loading. The V-shaped positioning groove 310 adapts to the shape of the materials, allowing them to be positioned within the groove. The barrier bar 304 prevents material movement, increasing the distance between materials. The movable slide groove 307 inside the limiting strip 306 restricts the movement direction of the positioning plate 309. By activating the electric push rod 308, the telescopic end of the electric push rod 308 moves the positioning plate 309 within the movable slide groove 307, thereby adjusting the position of the V-shaped positioning groove 310 to accommodate materials of different specifications. The positioning component 3, through the partition plate 302, first separates and transports the materials on the upper part of the conveyor belt 2. Then, when the distance between the materials is close, the operator can activate the electric push rod 303, causing the telescopic end of the electric push rod 303 to drive the barrier bar 304 down, thereby blocking the materials behind the barrier bar 304 and adjusting the distance between the materials. Then, when the materials are about to be transported to the end of the conveyor belt 2, they will be stuck in the V-shaped positioning groove 310 of the positioning plate 309. The V-shaped positioning groove 310 can center the materials, thus facilitating the subsequent material transfer. This utility model, through the installation of the partition plate 302 and the barrier bar 304, can effectively separate materials, avoid material congestion, and improve the safety and stability of material transportation. At the same time, the opening of the V-shaped positioning groove 310 on the side of the positioning plate 309 can also facilitate the positioning of materials, prevent the position of materials from shifting due to the movement of the conveyor belt 2, effectively improve the stability of material transportation, and facilitate the feeding of materials to the machine tool.

[0026] Furthermore, a second support frame 4 is fixedly installed on the top of the feeding rack 1, and the second support frame 4 is located in front of the first support frame 301. An electric push rod 5 is movably installed at the front end of the second support frame 4, and a moving component for the electric push rod 5 is provided at the front end of the second support frame 4.

[0027] The installation of the electric push rod 35 is used to drive the pneumatic three-jaw chuck 6 at the telescopic end to move up and down, so as to facilitate the transfer of materials inside the V-shaped positioning groove 310 through the pneumatic three-jaw chuck 6.

[0028] Furthermore, the moving component includes a second moving slide 501, a lead screw 502, a limiting slide 503, a moving slider 504, and a linear stepper motor 505. The second moving slide 501 is located in the middle of the front end of the second support frame 4. The lead screw 502 is fixedly installed inside the second moving slide 501. The limiting slide 503 is symmetrically distributed on the upper and lower sides of the second support frame 4.

[0029] The movable slider 504 is slidably connected inside the limiting slide groove 503 and is adapted to the limiting slide groove 503. The linear stepper motor 505 is movably installed inside the movable slide groove 501 and is threadedly connected to the lead screw 502. The linear stepper motor 505 is fixedly connected to the movable slider 504.

[0030] The movable slider 504 is fixedly connected to the electric push rod 5. The movable component is designed so that by activating the linear stepper motor 505, the movable component moves within the movable slide groove 501 via a threaded connection with the lead screw 502. During this movement, the linear stepper motor 505, due to its fixed connection to the movable slider 504 and the movable slider 504, and the fixed connection to the electric push rod 5, moves the electric push rod 5. This invention, by using the movement of the linear stepper motor 505 within the movable slide groove 501 to move the electric push rod 5, facilitates the transfer of materials within the V-shaped positioning groove 310, effectively improving practicality and convenience.

[0031] Furthermore, a pneumatic three-jaw chuck 6 is fixedly installed at the telescopic end of the electric push rod 3 5, and support columns 7 are fixedly connected to the bottom of the feeding rack 1 in a rectangular array. Anti-slip pads 8 are fixedly connected to the bottom of the support columns 7.

[0032] The pneumatic three-jaw chuck 6 can clamp materials by compressing air, and then transfer the materials by working with the linear stepper motor 505 and the electric push rod 3 5. The installation of the anti-slip pad 8 can increase the friction with the placement surface and improve the safety and stability of the structure.

[0033] Furthermore, the telescopic end of the electric push rod 308 is located inside the movable slide groove 307 and is fixedly connected to the positioning plate 309. The space between the V-shaped positioning groove 310 and the partition plate 302 is aligned.

[0034] The material is located between the partition plates 302 and can enter the interior of the V-shaped positioning groove 310 by being transported by the conveyor belt 2.

[0035] In summary:

[0036] In this utility model, when in use, the worker first places the material on the upper part of the conveyor belt 2. Then, the materials are separated for the first time by the installation of the partition plate 302. When the distance between the materials is too close, the electric push rod 303 can be activated, so that the telescopic end of the electric push rod 303 drives the blocking rod 304 to descend, thereby blocking the materials located behind the blocking rod 304, thus completing the adjustment of the distance between the materials. Then, when the material is about to be transported to the end of the conveyor belt 2, it will be stuck in the V-shaped positioning groove 310 of the positioning plate 309. The V-shaped positioning groove 310 is V-shaped, which can center the material.

[0037] Then, the linear stepper motor 505 is started, so that the moving component moves inside the moving slide 501 through the threaded connection with the lead screw 502. During the movement, the linear stepper motor 505 is also moved by the fixed connection between the linear stepper motor 505 and the moving slider 504, and the fixed connection between the moving slider 504 and the electric push rod 5, so that the electric push rod 5 is located at the top of the V-shaped positioning groove 310.

[0038] Then, the electric push rod 35 is activated, causing the pneumatic three-jaw chuck 6 at the telescopic end of the electric push rod 35 to descend. When the pneumatic three-jaw chuck 6 is outside the material, the pneumatic three-jaw chuck 6 is activated to clamp the material. Then, the electric push rod 35 is activated again, causing the pneumatic three-jaw chuck 6 at the telescopic end of the electric push rod 35 to lift the material. The material is then transferred by the movement of the linear stepper motor 505.
