Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw production technology, specifically to an automatic processing device for cross-grooves in screw production. Background Technology
[0002] A screw is a type of small, cylindrical or conical metal rod with threads, sharp at the end like a nail. It has a grooved or recessed head and is used alone. After the threads are machined, a groove is usually made at the top of the screw head. Some are flat, some are cross-shaped, and some are other shapes, to facilitate disassembly with a screwdriver.
[0003] As disclosed in the patent announcement CN218658184U, a screw cross-shaped groove processing device includes a production line and a guide channel. A support rod is mounted on the surface of the production line via bearings, and a rotating disk is fixedly connected to the top surface of the support rod. A support plate is fixedly mounted on the front of the production line, and a support base is fixedly connected to the top of the support plate. A protective sleeve is fixedly mounted on the top of the support base, and a connecting rod is inserted into the bottom end of the protective sleeve. A grinding disc is fixedly connected to the bottom end of the connecting rod. The beneficial effect of this invention, using the above technical solution, is that it allows the grinding disc to contact the top surface of the screw, facilitating automatic grinding and preventing burrs from affecting the quality.
[0004] Although the aforementioned patent can automatically grind the screws using a grinding disc, there is no limiting mechanism on the rotating disc, which makes it impossible to clamp the screws during grinding. This can cause the screws to shift or rotate during grinding due to lack of fixation, thus affecting processing accuracy and efficiency, and may even cause uneven wear or damage to the groove on the screw head.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This automatic cross-grooving processing device for screw production uses an electric push rod to drive the clamping ring and the bottom ring to cooperate with the support sleeve, thereby achieving bidirectional fixation of the screw during the processing.

Detailed Implementation
[0025] 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.
[0026] like Figure 1-5 As shown, this utility model provides a technical solution:
[0027] An automatic machining device for cross-grooving screws includes a worktable 1, a motor 2 fixedly connected to the center of its bottom end, a turntable 3 fixedly connected to the output shaft of the motor 2 passing through the worktable 1, and a support 4 vertically fixedly connected to the outside of one side of the worktable 1. A limit mechanism is provided between the support 4 and the turntable 3. The limit mechanism includes a limit retaining ring 19 movably disposed outside the turntable 3 and an electric push rod 6 fixedly connected to the lower right side of the support 4. The output shaft of the electric push rod 6 is fixedly connected to a lifting plate 7. A clamping ring 8 is fixedly connected side by side to the right side of the lifting plate 7. A bottom ring 9 is fixedly connected to the bottom end of the clamping ring 8. A plurality of workpiece positions 10 are evenly distributed on the outer periphery of the turntable 3. A support sleeve 11 is fixedly connected to the inner wall of the bottom end of the workbench 1. A discharge guide groove 12 is provided on the left side of the workbench 1. An opening 13 is provided on the side of the limiting ring 19 near the discharge guide groove 12. A vertical guide groove 14 is provided on the front of the support 4. A guide block 15 that slides vertically with the guide groove 14 is fixedly connected to the left side of the lifting plate 7. A cross frame 5 is fixedly fixed to the upper front end of the support 4. A grooving mechanism is provided below the front end of the cross frame 5. The grooving mechanism includes a hydraulic rod 16 fixedly connected to the top of the front end of the cross frame 5. A tool holder 17 is fixedly connected to the output shaft of the hydraulic rod 16. A cross pressure knife 18 is detachably installed on the tool holder 17. Both the workpiece position 10 and the support sleeve 11 are U-shaped structures.
[0028] In this embodiment, the electric push rod 6 drives the clamping ring 8 and the bottom ring 9 to cooperate with the support sleeve 11, thereby achieving bidirectional fixation of the screw during the processing. This effectively prevents the screw from shifting or rotating during the pressing process, and solves the problems of low processing accuracy and uneven groove wear caused by the lack of a limiting mechanism in the prior art.
[0029] Furthermore, through the synergistic effect of the limiting ring 19 and the opening 13, the outer side of the turntable 3 is closed during processing to ensure stable screw delivery. During unloading, the outer limiting is released through the opening 13, allowing the screw to automatically tilt and slide into the unloading guide groove 12.
[0030] Working principle: After the motor 2 starts, it drives the turntable 3 to rotate. The limit ring 19 on the outside of the turntable 3 prevents the screw from falling off during rotation. When the workpiece position 10 carries the screw to the processing position, the output shaft of the electric push rod 6 retracts and drives the lifting plate 7 to descend. The lifting plate 7 drives the clamping ring 8 to press the turntable 3 from the top to the bottom, while simultaneously driving the bottom ring 9 to penetrate into the workpiece position 10, cooperating with the support sleeve 11 to clamp the screw and keep it stable during processing. Then the hydraulic rod 16 pushes... The tool holder 17 descends, and the tool holder 17 drives the cross pressure knife 18 to press out a cross groove on the head of the screw. After the machining is completed, the electric push rod 6 pushes the lifting plate 7 to rise, so that the clamping ring 8 and the bottom ring 9 are reset and the screw is released from the fixation. The turntable 3 continues to rotate. When the workpiece position 10 moves to the opening 13 position of the limit stop ring 19, the screw loses the obstruction of the limit stop ring 19 on the outside. Under the action of gravity, the screw tilts to the outside and slides out from the workpiece position 10. Finally, it is discharged along the unloading guide groove 12, completing the automatic unloading.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
