Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a high-efficiency cutting and positioning fixture for angle steel. Background Technology

[0002] The high-efficiency angle steel cutting machine is an automated device specifically designed for angle steel cutting, which greatly improves processing efficiency. The equipment is equipped with a high-precision CNC system, which can automatically complete multi-angle and multi-specification cutting of angle steel according to preset programs, with an accuracy of ±0.5mm. It adopts high-power saw blades or plasma cutting technology, with fast cutting speed and can easily handle angle steel of different thicknesses.

[0003] The high-efficiency angle steel cutting and positioning fixture is an auxiliary device used for angle steel cutting. It is made of high-strength metal materials, and the fixture is easy to operate. It can significantly reduce the positioning time of angle steel and significantly improve the cutting efficiency. It has good versatility and stability and is widely used in industries such as steel structure processing and machinery manufacturing, providing reliable technical support for angle steel cutting.

[0004] Existing high-efficiency angle steel cutting positioning fixtures typically employ a fixed structure design, adapting to angle steel within a specific length range. When the angle steel length exceeds the preset size, it cannot be flexibly adjusted to achieve stable clamping, leading to easy displacement and shaking of the angle steel during the cutting process. This affects cutting accuracy and quality, reduces production efficiency, and increases material waste. Therefore, a high-efficiency angle steel cutting positioning fixture is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an efficient angle steel cutting and positioning fixture, which aims to improve the problem that existing technologies cannot clamp angle steels of different lengths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An angle steel high-efficiency cutting and positioning fixture includes a base, a motor is fixedly connected inside the base, a gear is fixedly connected to the drive end of the motor, two rack plates are slidably connected inside the base, the gear and the two rack plates are meshed, a fixing block is fixedly connected to the top of the rack plates, a rotating block is rotatably connected to the fixing block, a connecting rod is rotatably connected to the top of the fixing block, a pressing rod is rotatably connected to the other end of the rotating block, a fixing plate is fixedly connected to one end of the connecting rod, a second roller is rotatably connected to one end of the fixing plate, a first roller is rotatably connected to one end of the fixing plate, and a pushing assembly is provided inside the base.

[0008] As a further description of the above technical solution:

[0009] The pushing assembly includes a pull rod, one end of which is fixedly connected to a movable rod, one end of which is fixedly connected to a limiting plate, and both ends of the pull rod are fixedly connected to springs.

[0010] As a further description of the above technical solution:

[0011] A second motor is fixedly connected inside the base. A rotating rod is fixedly connected to the drive end of the second motor. A limiting rod is fixedly connected to one end of the rotating rod. A limiting frame is slidably connected to the outer wall of the limiting rod. A pushing rod is fixedly connected to the outer wall of the limiting frame. A pushing block is fixedly connected to one end of the pushing rod.

[0012] As a further description of the above technical solution:

[0013] The other end of the pressing rod is rotatably connected to one end of the connecting rod, and the outer wall of the gear is rotatably connected to the inner wall of the base;

[0014] As a further description of the above technical solution:

[0015] One end of the spring is fixedly connected to the inside of the base, and the bottom of the limiting plate is slidably connected to the inside of the base;

[0016] As a further description of the above technical solution:

[0017] The outer wall of the movable rod is slidably connected to the inner wall of the base, and the bottom of the limiting frame is slidably connected to the top of the base;

[0018] As a further description of the above technical solution:

[0019] The outer wall of the push rod is slidably connected to the top of the base, and the bottom of the push block is slidably connected to the top of the base;

[0020] As a further description of the above technical solution:

[0021] The outer wall of roller two is in contact with the outer wall of the L-shaped angle steel, and the outer wall of roller one is in contact with the outer wall of the L-shaped angle steel.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the worker pulls the pull rod, which moves the limiting plate to place the L-shaped angle steel in the base positioning area. After releasing the pull rod, the spring's rebound force resets it, pushing the limiting plate to fit tightly against the angle steel, thus completing a stable clamping. The second motor is started, which drives the rotating rod to rotate. The limiting rod fixed on it makes a circular motion in the limiting frame groove, converting the rotational motion into linear motion. Through the push rod and push block, the fixed L-shaped angle steel is accurately pushed to the cutting platform, providing reliable preparation for the subsequent cutting process.

[0024] 2. In this utility model, lifting the pressing rod drives the connecting rod. Rollers one and two at both ends of the right-angled fixed plate on the connecting rod can engage the edge of the angle steel to ensure the stability of the angle steel during cutting. Since the L-shaped angle steel varies in length in actual production, in order to adapt to angle steel of different lengths, the operator starts motor one. Its rotation drives the gear to rotate. The gear meshes with the rack plate, converting the rotational motion into the linear motion of the rack plate. The fixed blocks on the two rack plates are connected to the rotating block through the rotating shaft. The other end of the rotating block is rotatably connected to the pressing rod, which can adjust the size to adapt to angle steel of different lengths. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a high-efficiency angle steel cutting and positioning fixture, comprising a base 1, a motor 3 fixedly connected inside the base 1, a gear 4 fixedly connected to the drive end of the motor 3, the rotation of the motor 3 drives the gear 4 to rotate, the outer wall of the gear 4 is rotatably connected to the inner wall of the base 1, two rack plates 5 are slidably connected inside the base 1, the gear 4 is meshed with the rack plates 5, so that the rotational motion of the gear 4 can be accurately converted into the linear motion of the rack plates 5, a fixing block 6 is fixedly connected to the top of the rack plates 5, a rotating block 7 is rotatably connected to the fixing block 6, a connecting rod 9 is rotatably connected to the top of the fixing block 6, and a pressing rod 8 is rotatably connected to the other end of the rotating block 7. The other end is rotatably connected to one end of the linkage rod 9. One end of the linkage rod 9 is fixedly connected to a fixing plate 10. One end of the fixing plate 10 is rotatably connected to a roller 12 and a roller 11. The outer wall of roller 12 contacts the outer wall of the L-shaped angle steel 2, and the outer wall of roller 11 contacts the outer wall of the L-shaped angle steel 2. Roller 11 and roller 12 are rotatably connected to the fixing plate 10 through a rotating shaft and can rotate freely. As the fixing plate 10 moves, roller 12 and roller 11 approach the outer wall of the L-shaped angle steel 2. With the precise linkage design, the two rollers are tightly attached to different sides of the angle steel to form a stable clamping and positioning, laying a solid foundation for subsequent efficient cutting operations.

[0034] Reference Figure 3 and Figure 4The base 1 has a push assembly inside, which includes a pull rod 13. One end of the pull rod 13 is fixedly connected to a moving rod 14. The outer wall of the moving rod 14 is slidably connected to the inner wall of the base 1. One end of the moving rod 14 is fixedly connected to a limiting plate 15. The bottom of the limiting plate 15 is slidably connected to the inside of the base 1. Pulling the pull rod 13 moves the moving rod 14, which in turn moves the limiting plate 15. Both ends of the pull rod 13 are fixedly connected to springs 16. The springs 16 have good elasticity and will stretch and deform when the pull rod 13 moves, providing buffer and restoring force for the pull rod 13, making the entire pushing process smoother. One end of the spring 16 is fixedly connected to the inside of the base 1. A second motor 17 is fixedly connected to the inside of the base 1. The drive end of the second motor 17 is fixedly connected to a rotating rod 18. A limiting rod 19 is fixedly connected to one end of the limiting rod 19, and a limiting frame 20 is slidably connected to the outer wall of the limiting rod 19. When the second motor 17 starts, the rotating rod 18 will start to rotate with the drive of the second motor 17, thereby driving the limiting rod 19 to move in the groove of the limiting frame 20. The bottom of the limiting frame 20 is slidably connected to the top of the base 1. The rotation of the limiting rod 19 can drive the limiting frame 20 to move linearly along the top of the base 1. A push rod 21 is fixedly connected to the outer wall of the limiting frame 20, and the outer wall of the push rod 21 is slidably connected to the top of the base 1. A push block 22 is fixedly connected to one end of the push rod 21, and the bottom of the push block 22 is slidably connected to the top of the base 1. When the second motor 17 drives the rotating rod 18 to rotate, it drives the limiting rod 19 and the limiting frame 20 to move. The push rod 21 will push the push block 22 to move linearly along the top of the base 1, thereby realizing the pushing function of related components.

[0035] Working principle: When the operator pulls the pull rod 13, the pull rod 13 moves the moving rod 14, which in turn moves the limiting plate 15, placing the L-shaped angle steel 2 in the positioning area of ​​the base 1. Releasing the pull rod 13, under the strong rebound force of the spring 16, the pull rod 13 quickly returns to its original position, pushing the limiting plate 15 towards the L-shaped angle steel 2 until the limiting plate 15 is tightly pressed against the surface of the angle steel. The elastic clamping force securely fixes the angle steel. Then, the second motor 17 is started, driving the rotating rod 18 to rotate. One end of the rotating rod 18 is fixed with a limiting rod 19. The outer wall of the limiting rod 19 slides in the groove of the limiting frame 20. The outer wall of the limiting frame 20 is fixed with a push rod 21. The end of the push rod 21 is connected to the push block 22. As the rotating rod 18 continues to rotate under the drive of the motor 17, the limiting rod 19 makes a circular motion along the groove of the limiting frame 20, converting the rotational motion of the rotating rod 18 into the linear motion of the push rod 21. The push rod 21 drives the push block 22 to push the L-shaped angle steel 2 to the cutting platform, preparing for the subsequent cutting process.

[0036] When the L-shaped angle steel 2 reaches the cutting platform, the pressing rod 8 is lifted upwards. The pressing rod 8 drives the connecting rod 9, which is fixed with a fixing plate 10. The fixing plate 10 is right-angled, with roller 11 and roller 2 12 fixed at both ends. This ingenious right-angle design allows the fixing plate 10 to fit perfectly into the edge of the L-shaped angle steel 2, ensuring the stability of the angle steel during the cutting process. Since the length of the L-shaped angle steel 2 varies in actual production, in order to adapt to angle steel of different lengths, the operator starts the motor 3. The motor 3 rotates, driving the gear 4 to start rotating. The gear 4 and the rack plate 5 are meshed, so that the rotation of the gear 4 can be accurately converted into the linear motion of the rack plate 5. Fixing blocks 6 are installed on the two rack plates 5, and rotating blocks 7 are connected to the fixing blocks 6 through rotating shafts. The other end of the rotating blocks 7 is rotatably connected to the pressing rod 8, which supports the pressing rod 8 and adjusts the size to adapt to angle steel of different lengths.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
