Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically to a screw Phillips head slotting machine that is easy to maintain. Background Technology

[0002] A screw Phillips head grooving machine is a specialized machine tool primarily used for machining Phillips head or slotted head grooves on the end faces of screws or other hardware components. It is widely used in potentiometers, toys, water valves, lighting accessories, and other fields. It can efficiently process materials such as copper, iron, aluminum, and stainless steel, achieving high-precision milling through automated control. Suitable for mass production, it significantly improves processing efficiency and reduces defect rates.

[0003] Existing screw Phillips grooving machines have the following prominent problems in practical applications: the grooving mechanism, clamps and transmission components of traditional equipment are mostly fixed integrated designs, with compact internal structures and complex layouts, making it difficult to directly contact and maintain key components.

[0027] 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.

[0028] Please see Figure 1-7 This utility model provides a technical solution: a screw Phillips grooving machine that is easy to maintain, including a machine body 1, a turntable machine 5 installed in the middle of the rear side of the machine body 1, four sets of clamps 26 installed on the turntable machine 5, grooving devices 6 installed on the left and right sides of the rear side of the machine body 1, a clamping component and a feeding component installed on the left and right sides of the middle side of the machine body 1 respectively, a drive component installed inside the machine body 1, and a material conveying component installed on the top of the front side of the machine body 1.

[0029] The screw Phillips head grooving machine uses a conveying assembly to transport screws in an orderly manner to the front of the equipment body 1. The screws then fall precisely into the four sets of clamps 26 on the turntable 5 via the dropping groove 28 of the sliding plate 27. The turntable 5 drives the clamps 26 to rotate periodically. Before the screws are Phillips headed, the clamping assembly clamps the screws from the top inside the clamps 26 to ensure processing stability. Then, the screws to be processed are successively moved to the grooving devices 6 on the left and right sides of the rear of the equipment body 1 to achieve Phillips head grooving. The drive assembly simultaneously lifts and lowers the clamping assembly and the feeding assembly to achieve a continuous automated process and form an efficient cyclic processing.

[0030] The drive assembly includes a rotating rod 14. An installation plate 8 is fixedly installed inside the equipment body 1. Rotating seats 15 are fixedly connected to the bottom left and right sides of the installation plate 8. The rotating rod 14 rotates between the two sets of rotating seats 15. A second synchronous wheel 12 is fixedly sleeved on the right end of the rotating rod 14. A first fixing plate 9 is fixedly installed on the right side of the installation plate 8. A drive motor 10 is fixedly installed on the left side of the first fixing plate 9. A first synchronous wheel 11 is fixedly sleeved on the right end of the drive motor 10. A synchronous belt 13 is tensioned and sleeved between the first synchronous wheel 11 and the second synchronous wheel 12. Cams 34 are fixedly sleeved on both the left and right sides of the rotating rod 14.

[0031] When the drive assembly is in use, the drive motor 10 drives the rotating rod 14, which is mounted on the rotating seat 15, to rotate through the synchronous pulley 11, the synchronous belt 13 and the synchronous pulley 12. The cams 34 at both ends of the rotating rod 14 contact the clamping assembly and the feeding assembly respectively. The periodic rotation of the cams 34 realizes the lifting and lowering, thereby synchronously driving the lifting and lowering actions of the clamping assembly and the feeding assembly, and realizing the precise linkage between the clamping assembly and the feeding assembly.

[0032] The clamping assembly includes a sliding rod 25, which slides through the top left side of the equipment body 1. A fixing plate 30 is fixedly sleeved on the top of the sliding rod 25. A plug rod 31 is installed on the bottom right side of the fixing plate 30. A lifting plate 17 is fixedly connected to the bottom end of the sliding rod 25. A lifting rod 16 slides through the left side of the mounting plate 8. The top end of the lifting rod 16 is fixedly connected to the bottom side of the lifting plate 17. A first reset mechanism is installed on the left side of the fixing plate 30.

[0033] The first reset mechanism includes a sliding rod 32, the top of which is fixedly connected to the left side of the fixed plate 4 30, and the bottom of which slides through the top of the equipment body 1. A spring 2 33 is sleeved on the sliding rod 32.

[0034] When the clamping assembly is in use, the turntable machine 5 rotates periodically, moving the fixture 26 to the processing station. The lifting rod 16 is driven by the drive assembly, which in turn drives the lifting plate 17 to rise and fall, thereby driving the sliding rod 25 and the fixed plate 30 to rise and fall. The screw is tightened from the top by the insert rod 21 at the bottom right side of the fixed plate 30 to ensure processing stability. After clamping is completed, the fixed plate 30 is pushed by the spring 233, which drives the sliding rod 32 to rise and achieve reset.

[0035] The feeding assembly includes a second lifting rod 19, which is slidably installed on the top right side of the equipment body 1. A second fixing plate 21 is fixedly sleeved on the top of the second lifting rod 19. A first insert rod 29 is installed on the bottom left side of the second fixing plate 21. A second reset mechanism is installed on the right side of the second lifting rod 19. A pushing mechanism is installed on the rear side of the second lifting rod 19. The bottom of the second lifting rod 19 is slidably installed on the mounting plate 8.

[0036] The second reset mechanism includes a fixed plate 22. The left side of the fixed plate 22 is fixedly sleeved on the lifting rod 19. The right side of the fixed plate 22 is fixedly inserted with a sliding rod 23. The bottom end of the sliding rod 23 slides through the top of the equipment body 1. A spring 24 is sleeved on the sliding rod 23.

[0037] The feeding mechanism includes a sliding cylinder 20, which is fixedly installed on the top of the equipment body 1. A sliding plate 27 is slidably installed on the sliding cylinder 20, and a material drop groove 28 is provided on the front side of the sliding plate 27.

[0038] When the feeding assembly is in use, the sliding cylinder 20 pushes the sliding plate 27, so that the bottom of the material drop groove 28 on the sliding plate 27 is precisely positioned with the clamping groove of the clamp 26. Then, the driving assembly drives the lifting rod 19 to descend, thereby driving the fixed plate 21 to descend. The screw is precisely dropped into the clamp 26 on the turntable 5 by the insertion rod 29 installed on the bottom left side of the fixed plate 21. After the feeding is completed, the fixed plate 22 is pushed by the spring 24 sleeved on the sliding rod 23 to achieve reset.

[0039] The material conveying assembly includes a vibratory plate 3, which is installed on the top front side of the equipment body 1. A material conveying channel 4 is also installed on the top front side of the equipment body 1. The output end of the vibratory plate 3 is connected to the material conveying channel 4, and the output end of the material conveying channel 4 is connected to the material drop chute 28.

[0040] When the material conveying assembly is in use, the vibratory plate 3 conveys the screws in an orderly manner to the material conveying channel 4, and then to the material drop chute 28 of the sliding plate 27.

[0041] Lifting plates 18 are fixedly connected to the bottom ends of lifting rod 16 and lifting rod 19. The top of each lifting plate 18 has a mounting groove 35. Rotary wheels 36 are rotatably installed inside each mounting groove 35. The top sides of each rotating wheel 36 abut against the bottom sides of each cam 34. Through the periodic rotation of the cams 34, the rotating wheels 36 in the mounting grooves 35 are pushed down, thereby driving the lifting plates 18 down.

[0042] The equipment body 1 is equipped with four casters 2 at the bottom corners, which facilitates the overall movement and maintenance of the equipment.

[0043] Several heat dissipation holes 7 are provided on both the left and right sides of the equipment body 1. The heat dissipation holes 7 accelerate heat dissipation and ensure stable operation for a long time.

[0044] Working principle: The screw Phillips head grooving machine uses a vibratory feeder 3 to transport screws in an orderly manner to the feeding channel 4, and then to the dropping groove 28 of the sliding plate 27. The sliding cylinder 20 pushes the sliding plate 27 to make the bottom of the dropping groove 28 on the sliding plate 27 precisely positioned with the clamping groove of the clamp 26. Then, the drive motor 10 drives the rotating rod 14, which is rotatably mounted on the rotating seat 15, to rotate through the synchronous pulley 11, synchronous belt 13 and synchronous pulley 12. The periodic rotation of the cam 34 on the right side of the rotating rod 14 pushes the rotating wheel 36 in the mounting groove 35 of the right lifting plate 18, thereby driving the lifting rod 19 to descend, which in turn drives the fixed plate 21 to descend. The screw is accurately dropped into the clamp 26 on the turntable machine 5 by the insertion rod 29 installed at the bottom left side of the fixed plate 21. After feeding, the fixed plate 22 is pushed by the spring 24 sleeved on the sliding rod 23 to achieve reset.

[0045] The rotary table machine 5 continues to drive the fixture 26 to rotate periodically to the next processing station. Then, the drive motor 10 drives the rotating rod 14, which is mounted on the rotating seat 15, to rotate through the synchronous pulley 11, the synchronous belt 13 and the synchronous pulley 12. The periodic rotation of the cam 34 on the left side of the rotating rod 14 pushes the rotating wheel 36 in the mounting groove 35 of the left lifting plate 18, thereby driving the lifting plate 17 to rise and fall, which in turn drives the sliding rod 25 and the fixed plate 4 30 to rise and fall. The screw is tightened from the top by the insertion rod 2 31 at the bottom right side of the fixed plate 4 30 to ensure processing stability. After tightening, the fixed plate 4 30 is pushed by the spring 2 33, which drives the sliding rod 3 32 to rise and achieve reset. This ensures that the screw is tightened from the top of the screw inside the fixture 26 before the cross-grooving is performed, thus ensuring processing stability.

[0046] Then, the screws to be processed are successively transferred to the grooving devices 6 on the left and right sides of the rear of the equipment body 1 to achieve cross grooving, realize continuous automated process, and form efficient cycle processing.
