Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a manufacturing and welding tooling for a dry-process granulation mesh frame. Background Technology

[0002] Granulation frames are widely used in the machinery industry, especially in the granulation system of dry granulation machines. As a component of the granulation system, the granulation frame has high requirements for manufacturing precision.

[0003] A manufacturing fixture for a dry-process grain-forming mesh frame, application number CN202322927403.8, includes a fixture base plate, a fixture pressure plate disposed above the fixture base plate, and a support rod disposed between the fixture pressure plate and the fixture base plate. The fixture base plate has a positioning groove B that matches the shape of one side of the grain-forming mesh frame, and the fixture pressure plate has a positioning groove A that matches the shape of the other side of the grain-forming mesh frame. A set of locking nuts B is provided on the side of the fixture base plate along the outer shape of the positioning groove B, and a set of locking nuts A is provided on the side of the fixture pressure plate along the outer shape of the positioning groove A. This invention allows the grain-forming mesh frame parts to be placed in the fixture for positioning and locking before welding, avoiding inaccurate assembly and reducing welding deformation. After welding, the fixture can still be used for finishing, avoiding inaccurate clamping and ensuring the machining datum, significantly reducing machining difficulty and cost, and improving overall machining accuracy. However, after welding one end of the space frame, it is necessary to remove the space frame, flip it over, and then fix it again for welding, which results in low welding efficiency.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a manufacturing welding fixture for a dry-process granulation mesh frame, comprising:

[0021] The base plate 1 has a fixedly connected frame 2 and support rod. A pad 16 is fixedly connected to the lower end of both the frame 2 and the support rod. The lower end of the pad 16 has anti-slip textures to improve the overall stability of the device. An anti-slip pad layer made of rubber is provided inside the placement groove to improve the stability of the mesh frame body 9 within the placement groove. Multiple limiting components are installed on the base plate 1, and a positioning opening is provided on the base plate 1. Placement components are installed on the frame 2.

[0022] The placement assembly includes two lifting slots 3 on the upright frame 2. A threaded rod 4 is rotatably connected to the inner wall of one of the lifting slots 3. Two connecting frames 5 are slidably connected between the two lifting slots 3. The threaded rod 4 is threaded through the two connecting frames 5. A placement frame 6 is fixedly connected to one of the connecting frames 5, and a placement slot is opened on the placement frame 6. A positioning frame 7 is fixedly connected to the other connecting frame 5. The shape of the positioning frame 7 matches the shape of the positioning port. A servo motor 8 is fixedly installed on the upper end face of the upright frame 2. The rotating end of the servo motor 8 is fixedly connected to the threaded rod 4. A screen frame body 9 is installed between the placement slot and the positioning frame 7. The screen frame body 9 consists of two directional crossbars and a screen. A guide rod is fixedly connected to the inner wall of the other lifting slot 3. The guide rod slides through the two connecting frames 5, making the lifting of the connecting frame 5 more stable.

[0023] The limiting assembly includes two movable slots 10 on the base plate 1, each with a movable plate 11 slidably connected to it. Two spring frames 12 are fixedly connected to the base plate 1. Connecting rods 13 are fixedly connected to the side walls of the two movable plates 11. The two connecting rods 13 slidably pass through the base plate 1 and are respectively fixedly connected to the two spring frames 12. Support frames 14 are fixedly connected to the two movable plates 11. Multiple rollers 15 are rotatably connected to the two support frames 14. The surface of the rollers 15 is provided with a protective pad.

[0024] The detailed working process of this utility model is as follows:

[0025] First, the device is placed in the designated processing area. Then, one of the directional crossbars is placed in the placement slot on the placement frame 6. Subsequently, the servo motor 8 starts working, causing the threaded rod 4 to rotate. The two connecting frames 5 move down in the lifting slot 3, causing the placement frame 6 to move below the base plate 1. Then, the user passes the screen through the positioning frame 7 and the positioning port and installs it on one of the directional crossbars. When the screen is inserted into the positioning port, the screen will first contact the roller 15, causing the spring frame 12 to retract. The moving plate 11 moves in the moving slot 10, causing the two support frames 14 to move away from each other, allowing the screen to pass between the rollers 15. The rollers 15 on the two support frames 14 will limit and fix the screen, improving the stability of the screen and preventing the screen from moving and bending during welding, thus improving the welding quality. At this time, the other directional crossbar is installed on the screen and welded. When it is necessary to weld the bottom directional crossbar, the servo motor 8 starts working, causing the connecting frame 5, which was originally located below the base plate 1, to rise above the base plate 1, making it easier for the user to perform welding work again and improving welding efficiency.
