Technical Field

[0001] The utility model relates to the technical field of bar extractors for numerical control machine tools, and particularly relates to a bar extractor for intelligent numerical control machine tools. Background Technique

[0002] A numerical control machine tool is a machine tool controlled by computer digitalization. It can automatically process the parts to be machined according to a pre-programmed program. The main components of a numerical control machine tool include a numerical control device, a servo system, a detection and feedback device, and a machine tool body. The advantages of a numerical control machine tool include high machining accuracy, high machining efficiency, strong adaptability, high automation degree, etc. A bar extractor is usually used to automatically pull the bar on a CNC lathe, which can help improve production efficiency and reduce manual operation.

[0003] During the process of machining a bar on a numerical control machine tool, a bar extractor is needed to extract the bar for segmented machining. At present, most of the existing bar extractors use the cooperation of a spring and two clamping jaws to make the two clamping jaws perform a contraction movement, so as to quickly clamp the bar.

[0004] However, due to the limited clamping force, the existing bar extractors cannot stably clamp the bar of the mechanism, resulting in the situation that the bar is likely to fall off when the bar is extracted, which requires multiple extractions, consuming a lot of time, and seriously affecting the production efficiency of the bar, and cannot meet the production requirements. Therefore, a bar extractor for intelligent numerical control machine tools is proposed to solve the problems raised above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a bar extractor for intelligent numerical control machine tools, which solves the problems that the existing bar extractors cannot stably clamp the bar of the mechanism, resulting in the situation that the bar is likely to fall off when the bar is extracted, which requires multiple extractions, consuming a lot of time, and seriously affecting the production efficiency of the bar, and cannot meet the production requirements.

[0006] To achieve the above object, the utility model provides the following technical solution: A bar extractor for intelligent numerical control machine tools, comprising a bar extractor main body, a machine base and a bar, and a stable clamping mechanism is arranged inside the bar extractor main body;

[0007] The stable clamping mechanism includes a first V-shaped block and a second V-shaped block fixedly connected to the inner side of the stock puller body. A first lead screw is rotatably connected to the top of the first V-shaped block, and a second lead screw is rotatably connected to the top of the second V-shaped block. V-shaped clamping plates are threadedly connected to the outer surfaces of the first lead screw and the second lead screw. A fixed frame is fixedly connected to the top of the stock puller body, and a small driving motor is fixedly connected to the top of the fixed frame. A driving gear is fixedly connected to the upper section of the first lead screw, a chain is engaged with the outer surface of the driving gear, and a driven gear is fixedly connected to the upper section of the second lead screw.

[0008] Furthermore, fixed rods are fixedly connected to the tops of the first V-shaped block and the second V-shaped block, and the fixed rods are slidably connected to the V-shaped clamping plates.

[0009] Furthermore, through holes are formed in the four surrounding areas of the top of the stock puller body, and the tops of the first lead screw, the second lead screw, and the fixed rods all penetrate through the through holes and extend to the top of the stock puller body.

[0010] Furthermore, the output shaft of the small driving motor is fixedly connected to the top of the first lead screw, and the driving gear is chain-driven with the driven gear through the chain.

[0011] Furthermore, an electric push rod is fixedly connected to the left side of the machine base, the output shaft of the electric push rod is fixedly connected to a moving platform, connecting columns are fixedly connected to the four surrounding areas of the top of the moving platform, and the tops of the connecting columns are fixedly connected to the bottom of the stock puller body.

[0012] Furthermore, a sleeve is fixedly connected to the inner side of the machine base, and the sleeve is slidably connected to the moving platform.

[0013] Furthermore, moving pulleys are rotatably connected to the four surrounding areas of the bottom of the moving platform, and a sliding groove is formed in the inner bottom wall of the machine base.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] The stock extractor for the intelligent numerical control machine tool can stably clamp the bar stock. When in use, the operator only needs to start the small driving motor, which can drive the first lead screw to rotate clockwise. When the first lead screw rotates clockwise, through the chain drive cooperation between the driving gear, the chain and the driven gear, the second lead screw can be driven to rotate synchronously, and then the two V-shaped clamping plates move vertically downward at the same time. Finally, by continuously moving the two V-shaped clamping plates vertically downward, under the combined action of the first V-shaped block and the second V-shaped block, the bar stock can be clamped more stably, avoiding the situation of its falling off. Therefore, compared with the existing stock extractors, the function of stably clamping the bar stock is realized, and the situation of the bar stock falling off during extraction is avoided, so that it is not necessary to extract the bar stock multiple times, saving a lot of time, improving the production efficiency of the bar stock, and better meeting the production requirements.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5, A stock puller for an intelligent numerical control machine tool in this embodiment includes a stock puller main body 1, a machine base 2, and a bar stock 3. A stable clamping mechanism is provided inside the stock puller main body 1;

[0024] The stable clamping mechanism includes a first V-shaped block 4 and a second V-shaped block 5 fixedly connected to the inner side of the stock puller main body 1. A first lead screw 6 is rotatably connected to the top of the first V-shaped block 4, and a second lead screw 7 is rotatably connected to the top of the second V-shaped block 5. V-shaped clamping plates 8 are threadedly connected to the outer surfaces of the first lead screw 6 and the second lead screw 7. A fixed frame 9 is fixedly connected to the top of the stock puller main body 1, and a small driving motor 10 is fixedly connected to the top of the fixed frame 9. A driving gear 11 is fixedly connected to the upper section of the first lead screw 6. A chain 12 is engaged with the outer surface of the driving gear 11, and a driven gear 13 is fixedly connected to the upper section of the second lead screw 7. When in use, the staff only needs to start the small driving motor 10 to drive the first lead screw 6 to rotate clockwise. Among them, when the first lead screw 6 rotates clockwise, through the chain drive cooperation between the driving gear 11, the chain 12, and the driven gear 13, the second lead screw 7 can be driven to rotate synchronously, and then the two V-shaped clamping plates 8 move vertically downward at the same time. Finally, the two V-shaped clamping plates 8 move vertically downward continuously, and under the combined action of the first V-shaped block 4 and the second V-shaped block 5, the bar stock 3 can be clamped stably to prevent it from falling off.

[0025] Furthermore, compared with the existing stock pullers at present, the function of stably clamping the bar stock 3 is realized, and the situation of the bar stock 3 falling off during pulling out is avoided. Therefore, it is not necessary to pull out the bar stock 3 multiple times, saving a lot of time, improving the production efficiency of the bar stock, and better meeting the production requirements.

[0026] It should be noted that fixed rods 14 are fixedly connected to the tops of the first V-shaped block 4 and the second V-shaped block 5, and the fixed rods 14 are slidably connected to the V-shaped clamping plates 8. By setting the fixed rods 14, the effect of limiting the V-shaped clamping plates 8 is achieved.

[0027] It should be understood that through holes 15 are provided around the top of the stock puller main body 1. The tops of the first lead screw 6, the second lead screw 7, and the fixed rods 14 all penetrate through the through holes 15 and extend to the top of the stock puller main body 1. The output shaft of the small driving motor 10 is fixedly connected to the top of the first lead screw 6, and the driving gear 11 is in chain drive with the driven gear 13 through the chain 12.

Connecting columns 18 are fixedly connected to the four sides of the top of the moving platform 17, and the tops of the connecting columns 18 are fixedly connected to the bottom of the stock puller main body 1. Through the cooperation of the electric push rod 16, the moving platform 17, and the connecting columns 18, the stock puller main body 1 can be driven to move horizontally, so as to directly stretch the bar stock 3 that is stably clamped.

[0029] In addition, a sleeve 19 is fixedly connected to the inner side of the machine base 2. The sleeve 19 is slidably connected to the moving platform 17. Moving pulleys 20 are rotatably connected to the four peripheries of the bottom of the moving platform 17. A chute 21 is formed in the inner bottom wall of the machine base 2. Through the cooperation of the pulleys 20 and the chute 21, when the moving platform 17 moves horizontally, the pulleys 20 can slide inside the chute 21, thereby achieving the effect of assisting the movement and further reducing the moving pressure of the moving platform 17.

[0030] The working principle of the above embodiment is as follows:

[0031] During use, the staff first needs to start the electric push rod 16, so as to drive the blanking device main body 1 to move towards the bar stock 3 through the moving platform 17 until the bar stock 3 completely passes through the blanking device main body 1. When the bar stock 3 passes through the blanking device main body 1, at this time, only need to start the small drive motor 10, and the first lead screw 6 can be driven to rotate clockwise. Among them, when the first lead screw 6 rotates clockwise, through the chain drive cooperation between the drive gear 11, the chain 12 and the driven gear 13, the second lead screw 7 can be driven to rotate synchronously, and then the two V-shaped clamping plates 8 move vertically downward at the same time. Finally, the two V-shaped clamping plates 8 are continuously moved vertically downward, and under the combined action of the first V-shaped block 4 and the second V-shaped block 5, the bar stock 3 can be stably clamped. When the bar stock 3 is clamped, the moving platform 17 is reset by the electric push rod 16, and the stably clamped bar stock 3 can be directly stretched for processing.
