[0002] In machining and assembly processes, tooling tables are key equipment for ensuring workpiece machining accuracy and operational efficiency. Traditional tooling tables typically employ a single clamping or pressing structure, which has the following shortcomings: The fixing method is limited and cannot adapt to workpieces of different shapes and sizes, resulting in poor versatility. Insufficient stability of the workpiece fixation can easily lead to loosening or displacement during processing, affecting processing accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide an expandable tooling fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An expandable tooling fixture includes a tooling table and a second hinge block. L-shaped support plates and a support plate are fixedly connected to the top left and right sides of the tooling table. The L-shaped support plates are located on the side of the support plate. A cylinder is installed on the side of the L-shaped support plate away from the support plate. A hinge joint is installed at the pushing end of the cylinder. A second hinge seat is installed at the clamping part of the hinge joint. A first hinge seat is fixedly connected to the end of the second hinge seat away from the hinge joint. A first hinge block is hinged to the clamping part of the first hinge seat. A front block is installed at the front end of the first hinge block. A fixed plate is fixedly connected to the upper part of the side of the L-shaped support plate away from the cylinder. A pressure plate is fixedly connected to the top of the fixed plate. A pressure pin is fixedly connected to the front end of the pressure plate. A support vertical plate is fixedly connected to the inner side of the support plate, and a second pressure plate is installed on the top of the support vertical plate. A second cylinder is located on the rear part of the outer wall of the second pressure plate.

[0005] As a further embodiment of this utility model: the telescopic end of the cylinder two is equipped with a connector, and the top of the connector is hinged to the tail of the pressure plate two, and the hinge block two is snapped onto the upper surface of the pressure plate two.

[0006] As a further improvement of this utility model: a pressure handle is installed on the top front part of the hinge block one, and an operating component is pressed and provided on the lower part of the front block.

[0007] As a further improvement of this utility model, the hinge block two and the pressure plate two are the same size and specifications.

[0008] As a further improvement of this utility model: the lower part of the front end of the hinge joint is notched, and the top of the notch is located on the side of the lower surface of the operating member.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This device is practical and has high stability: Cylinder 1 and Cylinder 2 drive the corresponding clamping structures respectively, and together with the pressure pin, pressure plate 1, pressure plate 2 and other components, the operating parts are clamped and fixed from multiple directions, which effectively avoids loosening and displacement of the operating parts during the processing and ensures the processing accuracy. This utility model uses a cylinder-driven method to achieve automated clamping, which greatly improves operating efficiency and reduces manual labor intensity compared to the traditional manual fixing method. This utility model, through the design of a hinged structure, allows the clamping component to have a certain adjustment range, enabling it to adapt to operating parts of different sizes and shapes, thus expanding the applicability of the tooling table. In this utility model, the recessed design at the lower front end of the hinge joint reduces the contact area with the operating component when supporting and limiting it, thus avoiding large-area indentations or damage to the surface of the operating component. Its structure is more optimized and its design is more reasonable. Attached Figure Description

[0014] 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.

[0015] Please see Figures 1-3 In this embodiment of the utility model, an expandable tooling fixture includes a tooling table 1 and a hinge block 16. The tooling table 1 serves as the basic support component of the entire device, providing an installation platform for other components. L-shaped support plates 3 and support plates 14 are fixedly connected to the top left and right sides of the tooling table 1. The L-shaped support plates 3 are located on the side of the support plates 14. The L-shaped support plates 3 and support plates 14 together serve to support and install other functional components. A cylinder 5 is installed on the side of the L-shaped support plate 3 away from the support plate 14. The cylinder 5 provides power for the clamping action on this side. A hinge joint 6 is installed on the pushing end of the cylinder 5. A hinge seat 11 is installed on the clamping part of the hinge joint 6. A hinge seat 10 is fixedly connected to the end of the hinge seat 11 away from the hinge joint 6. A hinge block 9 is hinged to the clamping part of the hinge seat 10. Through the cooperation of these hinge structures, the pushing force of the cylinder 5 can be converted into the rotation or movement of the hinge block 9. A front block 12 is installed at the front end of the hinge block 9. An operating member 2 is pressed and installed at the lower part of the front block 12 for pressing the operating member 2. A pressure handle 13 is installed at the top front part of the hinge block 9. The pressure handle 13 can be used to manually adjust the position of the hinge block 9. A fixing plate 4 is fixedly connected to the upper part of the L-shaped support plate 3 on the side away from the cylinder 5. A pressure plate 7 is fixedly connected to the top of the fixing plate 4. A pressure pin 8 is fixedly connected to the front end of the pressure plate 7. The pressure plate 7 and the pressure pin 8 cooperate to further press and position the operating part 2 from above. The lower front end of the hinge joint 6 is recessed, and the top of the recess is located on the side of the lower surface of the operating member 2. This recessed structure supports the operating member 2 while reducing the contact area with the operating member 2, thus protecting the surface of the operating member 2 from damage. A support vertical plate is fixedly connected to the inner side of the support plate 14. The support vertical plate provides installation support for the pressure plate 2 17. The pressure plate 2 17 is installed on the top of the support vertical plate. A cylinder 2 15 is provided on the rear part of the outer wall of the pressure plate 2 17. The cylinder 2 15 provides power for the movement of the pressure plate 2 17. A connecting piece is installed at the telescopic end of cylinder 2 15, and the top of the connecting piece is hinged to the tail of pressure plate 2 17. Through this hinged connection, the telescopic movement of cylinder 2 15 can drive pressure plate 2 17 to rotate, thereby pressing or releasing the operating component 2. Hinge block 2 16 is snapped onto the upper surface of pressure plate 2 17. Hinge block 2 16 and pressure plate 2 17 are of the same size and specifications, ensuring the symmetry and interchangeability of the structure, and facilitating the replacement and maintenance of components.

[0016] The working principle of this utility model is as follows: When using, place 2 on top of 4, while also placing 2 below 7, to clamp the sides of 2. When in use, place the operating component 2 in the corresponding position on the tooling table 1. Start the cylinder 5, and the pushing end of the cylinder 5 extends. Through the transmission of the hinge structure such as the hinge joint 6, hinge seat 2 11, and hinge seat 10, the hinge block 9 is driven to rotate, so that the front block 12 presses the operating component 2 downward. At the same time, the pressure pin 8 on the pressure plate 7 presses and positions the operating component 2 from above. Simultaneously, cylinder 2 (15) is activated. The telescopic end of cylinder 2 (15) extends and retracts, driving pressure plate 2 (17) to rotate around the mounting point at the top of the supporting vertical plate via the connecting piece. This causes pressure plate 2 (17) to press against the other side of operating component 2. Through multi-directional pressing action, operating component 2 is ensured to be firmly fixed for subsequent processing operations. When it is necessary to remove the operating component 2, control cylinder 1 5 and cylinder 2 15 to reset, thereby driving each clamping component to loosen the operating component 2. The hinge block 2 16 and the pressure plate 2 17 are interchangeable.

[0017] Although the present invention 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 invention should be included within the protection scope of the present invention.
