Description

Technical Field

[0001] The utility model provides a positioning and fixing mechanism for sheet metal cutting, belonging to the technical field of sheet metal processing. Background Art

[0002] Sheet metal cutting is an important link in sheet metal processing, mainly used for cutting metal sheets according to design drawings to form the required shapes and sizes. There are several common types of sheet metal cutting methods: laser cutting, water jet cutting, plasma cutting

[0003] Shearing cutting, stamping cutting. Each cutting method has its own advantages and disadvantages. The choice of which method usually depends on factors such as the type of material, thickness, cutting accuracy requirements, and production costs.

[0004] Based on the above, the inventor found that:

[0005] In the prior art, positioning and fixing complement each other, the structure is relatively complex and mostly fixed with ordinary structures. If the inverted L-shaped structure is fixed, only the two sides are clamped and fixed, and it is not easy to find that the back side of the sheet metal part is not on the same horizontal plane. In this way, the fixed sheet metal part is not fixed standardly, is skewed from the beginning, will affect the subsequent processing accuracy and can only be cut ordinarily. When laser cutting, it is easy to damage the surface of the sheet metal processing table, which is not user-friendly.

[0006] Therefore, in view of this, the existing structure is studied and improved, and a positioning and fixing mechanism for sheet metal cutting is proposed to solve the above problems. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is that the traditional positioning and fixing mechanism for sheet metal cutting is not fixed standardly and is easy to damage the surface of the sheet metal processing table during laser cutting, which is not user-friendly.

[0008] In order to solve the above problems, the technical solution proposed by the utility model is: a positioning and fixing mechanism for sheet metal cutting, including a sheet metal processing table, a center positioning line is arranged on the sheet metal processing table and a fixing component is arranged on the sheet metal processing table. The fixing component includes a fixing plate, a driving component, two moving plates, and an auxiliary support component. The fixing plate is arranged inside the two moving plates, the moving plates are slidably connected to the sheet metal processing table, and the driving component is used to drive the two moving plates to move.

[0009] Further, the driving component includes a motor and a bidirectional threaded rod. A through hole is arranged on the sheet metal processing table. The motor is fixedly connected to the sheet metal processing table and the output end of the motor is fixedly connected to the bidirectional threaded rod. The other end of the bidirectional threaded rod passes through the through hole and is rotatably connected to the sheet metal processing table.

[0010] Further, the two moving plates are respectively placed on both sides of the bidirectional threaded rod and are respectively threadedly connected to the bidirectional threaded rod. A through groove is provided on the moving plate, and the fixing plate is placed in the through groove and is adapted to its inner diameter.

[0011] Further, a groove is provided on the sheet metal processing table, and an electric push rod I is fixedly connected between the groove and the fixing plate.

[0012] Further, sliding grooves are respectively provided on the outer walls on both sides of the sheet metal processing table, and sliding blocks adapted to the sliding grooves are respectively provided on both sides of the moving plate. The sliding blocks are slidably connected in the sliding grooves.

[0013] Further, the auxiliary support assembly includes a support frame, an electric push rod II, and a mounting plate. The electric push rod II is placed between the support frame and the mounting plate and is fixedly connected thereto. The support frame is placed on the sheet metal processing table.

[0014] Due to the adoption of the above technical solutions, the beneficial effects of the positioning and fixing mechanism for sheet metal cutting of the present utility model are as follows:

[0015] 1. Through the setting of the fixing plate, the back of the sheet metal part is close to the side of the fixing plate, ensuring no inclination in the horizontal direction. In cooperation with the fixing of the two moving plates, it is not easy to be fixed obliquely, the fixing is more standard, and it will not affect the subsequent processing accuracy.

[0016] 2. Through the setting of the auxiliary assembly, the triangular structure at the upper end of the support frame is used to contact the bottom of the sheet metal part. When laser cutting, the laser head is close to the surface of the sheet metal part. When laser cutting, it can prevent the laser cutting from damaging the surface of the sheet metal processing table. When ordinary cutting is performed, the auxiliary assembly can be removed, which is more user-friendly. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The problems of the prior art are fully interpreted in the technical background of this application. There are no problems of generalization or ambiguity. The problems to be solved by this application are specifically described in the following detailed description of the utility model and the specific embodiments, clarifying the technical problems that the technical solutions need to solve, and determining that the technical solutions of this application have beneficial effects compared with the objective prior art.

[0026] Please refer to Figures 1-4 As shown in the figure: The present utility model provides a positioning and fixing mechanism for sheet metal cutting, including a sheet metal processing table 1, a center positioning line 2 is provided on the sheet metal processing table 1, and a fixing component is provided on the sheet metal processing table 1. The fixing component includes a fixed plate 3, a driving component, two moving plates 4, and an auxiliary support component. The driving component includes a motor 5 and a bidirectional threaded rod 6. A through hole 7 is provided on the sheet metal processing table 1. The motor 5 is fixedly connected to the sheet metal processing table 1, and the output end of the motor 5 is fixedly connected to the bidirectional threaded rod 6. The other end of the bidirectional threaded rod 6 passes through the through hole 7 and is rotatably connected to the sheet metal processing table 1.

[0027] As Figures 2-4 shown, the auxiliary support component includes a support frame 11, a second electric push rod 12, and a mounting plate 13. The second electric push rod 12 is disposed between the support frame 11 and the mounting plate 13 and fixedly connected thereto. The support frame 11 is disposed on the sheet metal processing table 1.

[0028] The fixed plate 3 penetrates through the inner sides of the two moving plates 4. The moving plates 4 are slidably connected to the sheet metal processing table 1. The driving component is used to drive the two moving plates 4 to move.

[0029] The two moving plates 4 are respectively arranged on both sides of the bidirectional threaded rod 6, and the two moving plates are respectively threadedly connected to the bidirectional threaded rod 6. A through groove 14 is arranged on the moving plate 4, and the fixing plate 3 is arranged in the through groove 14 and is adapted to its inner diameter.

[0030] A groove 8 is arranged on the sheet metal processing table 1, and an electric push rod 9 is fixedly connected between the groove 8 and the fixing plate 3.

[0031] Chute 10s are respectively arranged on the outer walls on both sides of the sheet metal processing table 1, and sliders adapted to the chute 10s are respectively arranged on both sides of the moving plate 4. The sliders are slidably connected in the chute 10s.

[0032] The principle of a positioning and fixing mechanism for sheet metal cutting of the present utility model is as follows:

[0033] The central positioning line is the midline between the two moving plates. Start the motor to drive the bidirectional threaded rod to rotate, drive the two moving plates to approach or move away from each other, and the sliders move in the chutes to fix both sides of the sheet metal part. For example, Figure 1 as shown, the sheet metal part is an inverted U-shaped structure. Start the electric push rod 1 to drive the fixing plate to approach the side of the sheet metal part. The fixing plate moves in the through groove, and the two sides of the sheet metal part can be cut in the ordinary way. If laser cutting is used, the auxiliary support assembly needs to be placed on the sheet metal processing table, and start the electric push rod 2 to drive the support frame to approach the bottom of the sheet metal part as Figure 1 shown. The triangular sharp corner at the upper end of the support frame contacts the bottom of the sheet metal part, and then laser cutting is carried out.

[0034] Through the setting of the fixing component, the present utility model has more standard fixing, will not affect the subsequent processing accuracy, and is not easy to damage the surface of the sheet metal processing table during laser cutting, which is more user-friendly.

[0035] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they should all fall within the protection scope of the present utility model.
