Description

Technical Field

[0001] This utility model relates to the field of screw processing equipment technology, specifically an automatic screw tail trimming machine. Background Technology

[0002] A self-tapping screw is a fastener with a specially designed tail. It is a sub-type of self-tapping screw or self-drilling screw. Its tail is usually sharp or flat and cut. Some models have a scraping end or cutting groove. Its core function is to achieve efficient drilling and fastening in one step through the innovative tail structure. It is suitable for a variety of materials and industrial assembly scenarios.

[0003] Currently, the production of screws with tails often requires the use of cutting equipment, which is mainly used to achieve precise shaping of the tail structure. Existing cutting equipment has a simple structure. After manual feeding, it is necessary to operate a clamp on a saw blade milling machine for positioning and clamping. The overall operation is time-consuming and labor-intensive, increasing the labor intensity of workers. In addition, during the process of fixing the screws to be cut, direct clamping can easily damage the screws due to excessive force. Therefore, we have proposed an automatic screw tail-cutting machine. Utility Model Content

The material conveying motor is located on the outer side of one end of the crossbeam. The drive shaft is rotatably located between the two crossbeams and is located near the end of the material conveying motor. The driven shaft is located on the end of the crossbeam away from the drive shaft. The toothed conveyor belt is located on the outer side of the drive shaft and the driven shaft. Several placement seats are evenly distributed on the outer surface of the toothed conveyor belt. The positioning and cutting mechanism includes a strip mounting plate, a dual-head motor, a cutting blade, and positioning blocks. The strip mounting plate is disposed inside the mounting frame.

[0007] For example, at least one embodiment of this disclosure provides an automatic screw tail cutter, wherein the drive shaft and the driven shaft are connected by a toothed conveyor belt, and a limit groove is formed on the upper surface of the placement seat.

[0008] For example, at least one embodiment of this disclosure provides an automatic screw tail cutter, wherein the positioning and cutting mechanism further includes a hydraulic cylinder, a piston rod, a limiting slide rod and a clamping spring. The hydraulic cylinder is disposed on the upper surface of the mounting frame, the piston rod is disposed inside the hydraulic cylinder, and the lower end of the piston rod passes through the upper wall of the mounting frame and is connected to the strip mounting plate.

[0014] For example, support feet are provided at both ends of the lower surface of the beam.

[0015] The beneficial effects of this utility model are as follows: In this utility model, by setting a feeding mechanism, the automatic screw tail cutter has a limiting groove on the placement seat during use, which makes it easy to put the screw into the limiting groove, thereby playing a preliminary limiting role for the screw.

The system features a positioning and cutting mechanism with a mounting frame structure that facilitates the installation of a dual-head motor. The dual-head motor effectively drives two cutting blades to rotate synchronously. When the screw inside the mounting base moves directly below the positioning and cutting mechanism, the hydraulic cylinder activates, pushing the strip mounting plate downwards via the piston rod. During this downward movement, the mounting plate, through a compression spring, causes the positioning block to move downwards, first contacting the mounting base. The mounting plate continues to compress the compression spring, and the positioning block cooperates with the mounting base to effectively clamp and fix the screw inside. The cutting blade then completes the cutting of the screw's tail during its downward movement. The operation is simple, time-saving, and labor-saving. Attached Figure Description

[0025] like Figures 1-5As shown, it illustrates an automatic screw tail cutter according to an embodiment of the present invention, including two parallel crossbeams 1, a material conveying mechanism 3 between the two crossbeams 1, a mounting frame 5 on the upper surface of the crossbeams 1, and a positioning and cutting mechanism 6 on the mounting frame 5. The material conveying mechanism 3 includes a material conveying motor 301, a drive shaft 302, a driven shaft 303, and a toothed conveying belt 304. The material conveying motor 301 is located on the outer side of one end of the crossbeam 1. The drive shaft 302 is rotatably located between the two crossbeams 1 and is located near the end of the material conveying motor 301. The driven shaft 303 is located on the end of the crossbeam 1 away from the drive shaft 302. The toothed conveying belt 304 is located on the outer side of the drive shaft 302 and the driven shaft 303. A plurality of placement seats 305 are evenly spaced on the outer surface of the toothed conveying belt 304. The positioning and cutting mechanism 6 includes a strip mounting plate 603, a dual-head motor 604, a cutting blade 605, and positioning blocks 608. The strip mounting plate 603 is installed inside the mounting frame 5. A mounting frame is provided at the center of the lower surface of the strip mounting plate 603 via a connecting column. The dual-head motor 604 is installed inside the mounting frame. There are two cutting blades 605, which are respectively installed at the two output ends of the dual-head motor 604. The mounting frame facilitates the installation of the dual-head motor 604. When the dual-head motor 604 is working, it can effectively drive the two cutting blades 605 to rotate synchronously. There are two positioning blocks 608, which are respectively installed below both ends of the strip mounting plate 603.

[0026] This embodiment provides a structure consisting of a feeding motor 301, a drive shaft 302, a driven shaft 303, a toothed conveyor belt 304, a placement seat 305, a hydraulic cylinder 601, a piston rod 602, a strip mounting plate 603, a dual-head motor 604, a cutting blade 605, a clamping spring 607, and a positioning block 608. During use, the placement seat 305 effectively holds screws. The feeding motor 301 drives the drive shaft 302, which, in turn, drives the toothed conveyor belt 304 to rotate, thus effectively feeding the screws. When the screw inside the placement seat 305 moves directly below the positioning and cutting mechanism 6, the hydraulic cylinder 601 operates, pushing the strip mounting plate 603 downwards via the piston rod 602. During the downward movement of the strip mounting plate 603, the positioning block 608 moves downwards via the compression spring 607, first contacting the placement seat 305. The strip mounting plate 603 continues to compress the compression spring 607 and move downwards. The positioning block 608 can cooperate with the placement seat 305 to effectively clamp and fix the screw inside the placement seat 305. Then, the cutting blade 605 completes the cutting of the screw tail during the downward movement. The operation is simple, time-saving, and labor-saving.

[0027] See in some examples Figure 3 and Figure 4 One end of the drive shaft 302 passes through the side wall of the crossbeam 1 and is connected to the output end of the conveying motor 301. Two toothed conveying belts 304 are provided, and the two toothed conveying belts 304 are respectively provided at both ends of the outer surface of the drive shaft 302 and the driven shaft 303. The drive shaft 302 and the driven shaft 303 are connected by the toothed conveying belts 304. A limit groove 306 is provided on the upper surface of the placement seat 305.

[0028] In the above structure, by opening a limiting groove 306 on the placement seat 305, it is easy to put the screw into the limiting groove 306, which can play a preliminary limiting role for the screw. When the feeding motor 301 works, it can effectively drive the drive shaft 302 to rotate, and then, with the cooperation of the driven shaft 303, it can effectively drive the toothed feeding belt 304 to rotate, thereby realizing the effective feeding of the screw.

[0029] Further as Figure 5 As shown, the positioning and cutting mechanism 6 also includes a hydraulic cylinder 601, a piston rod 602, a limiting slide rod 606, and a clamping spring 607. The hydraulic cylinder 601 is disposed on the upper surface of the mounting frame 5, and the piston rod 602 is disposed inside the hydraulic cylinder 601. The lower end of the piston rod 602 passes through the upper wall of the mounting frame 5 and is connected to the strip mounting plate 603.

[0030] In the above structure, the piston rod 602 moves up into the cylinder body to retract or moves down to extend out of the cylinder body when the hydraulic cylinder 601 works. The up and down movement of the piston rod 602 can drive the strip mounting plate 603 to move up and down synchronously.

[0031] In a preferred embodiment, the strip mounting plate 603 has sliding holes at both ends. The upper end of the limiting slide rod 606 passes through the sliding hole and is provided with a limiting plate. The limiting slide rod 606 is slidably connected to the strip mounting plate 603. The lower end of the limiting slide rod 606 is connected to the positioning block 608. The compression spring 607 is sleeved on the outer surface of the limiting slide rod 606. The upper and lower ends of the compression spring 607 are provided with connecting pieces. The upper end of the compression spring 607 is connected to the strip mounting plate 603 through the connecting piece, and the lower end of the compression spring 607 is connected to the positioning block 608 through the connecting piece.

[0032] In the above structure, by setting a limiting slide bar 606, during the movement of the positioning block 608 driven by the compression spring 607 of the strip mounting plate 603, the limiting slide bar 606 can effectively limit the movement, ensuring that the positioning block 608 moves vertically and preventing the positioning block 608 from shifting position. During the downward movement of the strip mounting plate 603, the positioning block 608 is driven downward by the compression spring 607 and first contacts the placement seat 305. The strip mounting plate 603 continues to compress the compression spring 607 and move downward. The positioning block 608 can cooperate with the placement seat 305 to effectively clamp and fix the screw inside the placement seat 305. Then, the cutting blade 605 completes the cutting of the screw tail during the downward movement.

[0033] In a preferred embodiment, an inner support frame 4 is provided at the middle of the inner wall of each of the two crossbeams 1. A boss is provided at the front end of the inner support frame 4. The lower end surface of the placement seat 305 extending out of the toothed conveyor belt 304 contacts the boss at the front end of the inner support frame 4.

[0034] In the above structure, through the inner support frame 4 and the boss structure at its front end, when the screw inside the placement seat 305 moves to the position cutting mechanism 6 directly below, the front end of the placement seat 305 is located on the upper surface of the boss of the inner support frame 4. When the positioning block 608 moves down to cooperate with the placement seat 305 to press the screw, the boss can effectively provide bottom support for the placement seat 305.

[0035] In a preferred embodiment, support feet 2 are provided at both ends of the lower surface of the crossbeam 1.

[0036] In the above structure, the supporting foot 2 structure can effectively support the crossbeam 1 and ensure the overall stability.

[0037] Working principle: A limiting groove 306 is provided on the placement seat 305 to facilitate the insertion of screws into the limiting groove 306, thereby providing initial limiting for the screws. When the feeding motor 301 is working, it can effectively drive the drive shaft 302 to rotate, which in turn can effectively drive the toothed conveyor belt 304 to rotate with the cooperation of the driven shaft 303. During the movement of the toothed conveyor belt 304, it drives the placement seat 305 and the screws placed on it to move synchronously, thereby achieving effective conveying of the screws.

[0038] Furthermore, the mounting frame facilitates the installation of the dual-head motor 604. The dual-head motor 604 effectively drives the two cutting blades 605 to rotate synchronously. When the screw inside the placement seat 305 moves directly below the positioning and cutting mechanism 6, the hydraulic cylinder 601 operates, pushing the strip mounting plate 603 downwards via the piston rod 602. During this downward movement, the strip mounting plate 603, through the compression spring 607, drives the positioning block 608 to move downwards, first contacting the placement seat 305. The strip mounting plate 603 continues to compress the compression spring 607, allowing the positioning block 608 to cooperate with the placement seat 305, effectively clamping and fixing the screw inside. Thus, the cutting blade 605 completes the cutting of the screw's tail during the downward movement. The operation is simple, time-saving, and labor-saving. With the inner support frame 4 and its front boss structure, when the screw inside the placement seat 305 moves to the position cutting mechanism 6 directly below, the front end of the placement seat 305 is located on the upper surface of the boss of the inner support frame 4. When the positioning block 608 moves down to cooperate with the placement seat 305 to press the screw, the boss can effectively support the placement seat 305.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
