[0002] The truck head refers to the front part of the truck, which includes a cab, an engine, a steering system, and other mechanical and electronic components necessary for controlling the vehicle operation. The truck head is usually connected to a trailer through a fifth-wheel coupling device (also known as a turntable or gooseneck) behind the cab, enabling the truck to tow different trailers. Depending on the type of truck, the design and size of the head will also vary. For example, there are various types such as heavy trucks, semi-trailer tractors, dump trucks, etc. And during the production process of truck head parts, a punching device and a turning device are required to turn and punch some positions to facilitate assembly.

[0003] However, when the existing punching device is working, it usually relies on workers to manually use external bolts or other fixing tools to limit and install between the truck head parts and the turning device, which is time-consuming and laborious. After the parts are turned over and punched, due to the small clamping area of the turning parts, the vibration generated during the punching process and the gravity of the parts themselves are likely to cause the punching positions of the parts to tilt, making it inconvenient to use. Therefore, we have proposed a head turning tooling with the function of being easy to use and urgently need to be developed. Summary of the Utility Model

[0025] When the existing punching device is working, it usually relies on workers to manually use external bolts or other fixing tools to limit the installation between the parts of the truck head and the flipping device, which is time-consuming and laborious. After the parts are flipped and punched, due to the small clamping area of the flipping parts, the vibration generated during the punching process and the gravity of the parts themselves are likely to cause the punching position of the parts to tilt, which is not convenient for use. Therefore, through research, the inventor provides a head flipping tooling. By the combined use of the clamping component and the auxiliary support component, the clamping and limiting of the truck head parts and the auxiliary support of the parts during drilling are realized, thereby avoiding the tilting of the parts during drilling, further providing the stability during drilling, and using the clamping component to clamp and limit parts of different thickness models, thus avoiding the need for users to manually use external fixing tools for installation and disassembly, saving time and effort, reducing the work burden of users, and improving the work efficiency of users, being convenient for use, and thus solving the above defects.

[0026] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Please refer to Figures 1 to 8 , the embodiment of the present invention provides a head flipping tooling, including two mounting brackets 1. A bearing seat 2 is connected to the top of the mounting bracket 1. A positioning rod 3 is rotatably connected to the inner cavity of the bearing seat 2. One end of the positioning rod 3 is connected to a rotating disk 4. A first motor 5 connected to the rotating disk 4 is connected to the top of the mounting bracket 1;

[0028] Please refer to Figures 2 to 8, on the side of the rotary disk 4 opposite to the positioning rod 3, a clamping assembly 6 is jointly provided. The clamping assembly 6 includes a fixed box 61 connected to the outer surfaces of the positioning rod 3 and the rotary disk 4. The front side of the fixed box 61 is connected to a fixed block 62. A cylinder 63 is disposed through the inner surface of the fixed block 62. One end of the cylinder 63 is bolted to the fixed box 61. Among them, the fixed box 61 on the right side is bolted to the cylinder 63. The output end of the cylinder 63 penetrates into the inner cavity of the fixed box 61 and is connected to a moving plate 64. The bottom of the moving plate 64 is slidably connected to the inner cavity of the fixed box 61. Both sides of the moving plate 64 are rotatably connected to a connecting plate 65. Both sides of the inner cavity of the fixed box 61 are rotatably connected to a rotating rod 66. The outer surface of the connecting plate 65 is rotatably connected to an L-shaped pushing frame 67. A push rod 68 is slidably connected to the inner cavity of the L-shaped pushing frame 67. Two limiting plates 610 arranged symmetrically up and down are slidably connected to the outer surface of the left fixed box 61. The right fixed box 61 is provided with two open structures adapted to the limiting plates 610. And a plurality of protective patterns are provided on the surface of the limiting plates 610. Two symmetrically arranged positioning blocks 69 are connected to the outer surface of the limiting plates 610. The outer surface of the positioning block 69 is rotatably connected to the push rod 68. Among them, the positioning block 69 is installed with a bearing by inlaying in the inner cavity and is rotatably connected to the push rod 68 by using a shaft body;

[0029] Specifically, when the user needs to clamp different parts of the truck head, the parts can be placed between the two limiting plates 610, and then the cylinder 63 is started. The output end of the cylinder 63 contracts and pushes the moving plate 64 to move forward. During the movement of the moving plate 64, it pushes the two connecting plates 65 and pushes the L-shaped pushing frame 67 to swing in the opposite direction with the rotating rod 66 as the center. Then the two L-shaped pushing frames 67 push the two push rods 68 to move in the opposite direction. The push rod 68 drives the positioning block 69 and the limiting plate 610 to move synchronously at the same time, so as to clamp parts of different thickness models and facilitate clamping;

[0030] Please refer to Figures 2 to 7, an auxiliary support assembly 7 for cooperating with the clamping assembly 6 is provided at the rear side of the mounting bracket 1. The auxiliary support assembly 7 includes a protective box 71 connected to the rear side of the mounting bracket 1. A positioning box 72 is connected to the rear side of the protective box 71. A second motor 73 is bolted inside the positioning box 72. The output shaft of the second motor 73 penetrates through the protective box 71 and is connected to a threaded rod 74, and the front end of the threaded rod 74 is rotatably connected to the inner cavity of the protective box 71. Two opposite external threads are provided on the surface of the threaded rod 74. Two first threaded blocks 75 and second threaded blocks 76 which are symmetrically arranged front and back are threadedly connected to the surface of the threaded rod 74. Internal threads adapted to the threaded rod 74 are provided inside the first threaded block 75 and the second threaded block 76. Open structures are provided on both the front and back sides of the top of the protective box 71. Two reset springs 77 are connected to both sides of the top of the second threaded block 76. The top ends of the reset springs 77 are connected to a support plate 78, and both sides of the support plate 78 are smooth;

[0031] Specifically, after clamping the components, the second motor 73 can be started. The output shaft of the second motor 73 drives the threaded rod 74 to rotate. The threaded rod 74 uses opposite threads and drives the first threaded block 75 and the second threaded block 76 to move in opposite directions, so that the second threaded block 76 drives the reset spring 77 and the support plate 78 to move synchronously. When moving to a suitable position, the support plate 78 presses the reset spring 77, causing the support plate 78 to move downward, and using the support plate 78 to assist in supporting the components for easy support.

[0032] In summary, the working principle of a front-end flipping tooling according to an embodiment of the present invention: First, the user places the truck front-end components to be drilled into the clamping assembly 6.
