[0012] Compared with the prior art, the beneficial effects of this utility model are: this high-precision screw cutting device is reasonable and has the following advantages:

[0013] (1) Through the cooperation of clamping plates, rotating plates, connecting shafts, push plates, and baffles, the problem of unstable cutting quality caused by screw shaking is avoided. When the cutting blade starts to cut the screw, the clamping plates and push plates cooperate closely to precisely clamp the surface of the screw, preventing any displacement or shaking during high pressure and cutting. This allows the cutting blade to maintain a stable cutting depth and angle, thereby improving cutting accuracy, reducing cutting errors, and ultimately improving the cutting quality of the screw. When the cutting blade finishes cutting and returns to its initial position, the structural design of the clamping plates and rotating plates ensures timely release of the screw. The function of the rotating plates and connecting shafts allows the clamping plates to be released flexibly, thus preventing the screw from being restricted in subsequent operations and allowing it to move freely or enter the next process. The key advantage of this design is that it can quickly release the fixation without additional manual intervention, reducing operation time and complexity, and further improving overall work efficiency.

[0014] (2) Through the design of the inclined groove and the vacuum cleaner, the waste can be quickly sucked into the vacuum cleaner, avoiding the accumulation of waste. The biggest advantage of this design is that it reduces the accumulation of waste on the upper part of the operating table, thereby keeping the operating table clean, reducing the frequency of waste cleaning by operators, and greatly saving the time and labor cost of manual cleaning; With the cooperation of the moving mechanism, the screw can be accurately and stably fed towards the operating table continuously. The precise control of the moving mechanism, combined with the efficient feeding design, enables the screw to maintain a constant speed during the cutting process and automatically position itself to the appropriate position, making full preparation for the next cut; And by adjusting the translation component, the user can adjust the cutting size requirements according to the different diameters or lengths of the screw; The addition of this function enables the device to handle screws of different specifications, further improving the applicability and flexibility of the device, and meeting the diverse needs of different production scenarios; Waste generated during the cutting process tends to accumulate around the operating table, which not only affects the cleanliness of the operation, but may also affect the cutting accuracy.

[0022] 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.

[0023] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0024] Example:

[0025] In this embodiment, a high-precision screw cutting device includes a base 1, a screw 7, and an operating table 6. The base 1 has a moving mechanism on its upper end, a clamping seat 3 on one side of the moving mechanism, and a guide plate 12 on the other end. One end of the screw 7 is located inside the clamping seat 3, and the other end of the screw 7 extends through the guide plate 12 into the upper end of the operating table 6. A support frame 4 is provided on one side of the operating table 6, and a chain lifting mechanism 9 is provided on the upper end of the support frame 4. A cutting blade 10 is provided at the output end of the chain lifting mechanism 9. A connecting plate 11 is provided on one side of the chain lifting mechanism 9. A translation component is provided inside the connecting plate 11. The translation component includes a lead screw 23. The lead screw 23 is connected to a baffle 16. A feeding trough 15 is provided below the baffle 16 and on the operating table 6. Connecting shafts 20 are provided on both sides of the upper end of the feeding trough 15. A rotating plate 19 is provided at one end of the connecting shaft 20, and a push plate 21 is provided at the other end of the connecting shaft 20. A fixing component is provided at the upper end of the rotating plate 19, and the push plate 21 is vertically aligned with the baffle 16.

[0026] When cutting the screw 7, the chain lifting mechanism 9 is activated, causing the cutting blade 10 and the baffle 16 to move downwards simultaneously. At this time, the lower end of the baffle 16 passes through the feeding groove 15 and also moves downwards. Figure 3 As shown, the lower end of the baffle 16 pushes one end of a pair of push plates 21, causing the push plates 21 to rotate downwards, which in turn drives the connecting shaft 20 to rotate in the same direction, thereby driving a pair of rotating plates 19 to rotate in the same direction. This causes the clamping plates 25 on the rotating plates 19 to move toward the screw 7, thus fixing the screw 7. The cutting blade 10 is driven by a rotating motor. When the cutting blade 10 contacts the screw 7, the screw 7 is firmly fixed under the action of the pair of clamping plates 25. Therefore, when the cutting blade 10 cuts the screw 7, the screw 7 will not shake, making the cutting operation of the screw 7 more stable and improving the cutting quality of the screw 7.

[0027] The moving mechanism includes a rack 5 and a guide post 8. A pair of racks 5 are respectively disposed on both sides of the base 1. Electric gears 14 are provided on both sides of the lower end of the clamping seat 3 and the guide disk 12. The electric gears 14 mesh with the racks 5. The guide post 8 is horizontally disposed in the base 1 and parallel to the racks 5. The guide post 8 passes through the lower end of the clamping seat 3 and the guide disk 12.

[0028] The aforementioned electric gear 14 is a device in which a motor drives a gear, and the gear meshes with the rack 5;

[0029] Through the design of the moving mechanism, when the electric gear 14 is activated, the guide plate 12 and the clamping seat 3 can be driven to move horizontally within the base 1 in cooperation with the rack 5 and the guide post 8. The guide plate 12 is used to limit the screw 7, and the clamping seat 3 is used to fix one end of the screw 7, so that the guide plate 12 is fixed on one side of the operating table 6. Then, by moving the clamping seat 3 toward the guide plate 12, the screw 7 can be moved toward the upper end of the operating table 6, so that the screw 7 can continue to perform cutting operations.

[0030] The translation component includes a moving groove. The lower end of the connecting plate 11 is provided with a moving groove. A lead screw 23 is horizontally provided in the moving groove. One end of the lead screw 23 passes through the moving groove and a rotating handle 22 is provided on one side. The lead screw 23 is threadedly connected to the upper end of the baffle 16.

[0031] By rotating the handle 22, the screw 23 can be rotated, which in turn causes the baffle 16 to move horizontally in the moving groove. The lower end of the baffle 16 can abut against the screw 7. Combined with the design of the clamp and the clamping seat 3, the cutting length of the screw 7 can be adjusted.

[0032] The fixing component includes a telescopic box 24, a spring 26 is provided on one side of the upper end of the rotating plate 19, the spring 26 is connected to one side of the telescopic box 24, the outer side of the telescopic box 24 is movably connected to the rotating plate 19, and a clamping plate 25 is provided at the end away from the spring 26.

[0033] Through the design of the telescopic box 24, spring 26, and clamping plate 25, when a pair of rotating plates 19 rotate in opposite directions, they can drive the clamping plate 25 on them to clamp and fix the screw 7, thereby strengthening the stability of the screw 7 during cutting and ensuring the cutting quality of the screw 7.

[0034] The rotating handle 22 is provided with damping between it and the connecting plate 11.

[0035] The surface of the clamping plate 25 is provided with a rubber pad;

[0036] With the design of rubber pads on the surface of the clamping plates 25, when a pair of clamping plates 25 clamp and fix the screw 7, the screw 7 is threaded, which can prevent the clamping plates 25 from damaging the threads on the surface of the screw 7.

[0037] The lower end of the feeding trough 15 is provided with an inclined trough 17, and a vacuum cleaner 18 is provided on one side of the inclined trough 17.

[0038] The design of a vacuum cleaner 18 on one side of the inclined groove 17 can remove cutting waste generated around the feed chute 15, reducing the accumulation of waste on the surface of the workbench 6, reducing the frequency of waste cleaning by operators, and saving labor.

[0039] The base 1 has a discharge port 2 on its side, and the discharge port 2 is connected to the lower side of the inclined groove 17.

[0040] With the design of the discharge port 2 and the inclined groove 17, the cut screw 7 can fall from the discharge trough 15 into the inclined groove 17 under the action of gravity, and then be discharged through the discharge port 2, which makes it convenient for operators to collect the screw 7 and saves labor.

[0041] Working principle: When using this device, first check its integrity. Fix one end of the screw 7 inside the clamping seat 3, and ensure the other end of the screw 7 passes through the guide plate 12 and extends above the operating table 6, abutting against the baffle 16. When cutting the screw 7, activate the chain lifting mechanism 9, causing the cutting blade 10 and the baffle 16 to move downwards simultaneously. At this time, the lower end of the baffle 16 also moves downwards through the feeding chute 15. Figure 3 As shown, the lower end of the baffle 16 pushes one end of a pair of push plates 21, causing the push plates 21 to rotate downwards, which in turn drives the connecting shaft 20 to rotate in the same direction. This, in turn, drives a pair of rotating plates 19 to rotate in the same direction, causing the clamping plates 25 on the rotating plates 19 to move toward the screw 7, thereby fixing the screw 7. The cutting blade 10 is driven by a rotating motor. When the cutting blade 10 contacts the screw 7, the screw 7 is firmly fixed under the action of the pair of clamping plates 25. Therefore, when the cutting blade 10 cuts the screw 7, the screw 7 will not shake, making the cutting operation of the screw 7 more stable and improving the cutting quality of the screw 7. The cut screw 7 segments fall from the feeding groove 15 into the inclined groove 17 and are then removed from the feeding port 2, which is convenient for the operator to collect. The design of the vacuum cleaner 18 allows the cutting waste generated around the upper end of the feeding groove 15 to enter the vacuum cleaner 18 through the inclined groove 17, reducing the labor cost of the operator.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
