It is mainly suitable for machining complex parts such as plates, discs, molds and small shells. The vertical machining center can complete processes such as milling, boring, drilling, tapping and cutting threads. It has the advantages of high degree of automation, high machining precision and high production efficiency.
[0003] However, some existing vertical machining fixtures for vertical machining centers still have problems. For example, they cannot properly position and clamp the workpiece during machining, affecting machining accuracy. They cannot simultaneously fix multiple workpieces, and the workpiece fixing and removal process is inconvenient, which affects ease of use and machining efficiency. These fixtures are not suitable for machining products that require high positioning, clamping accuracy, and machining efficiency, such as EFI valve bodies. Due to their complex structure and precise machining requirements, EFI valve bodies require high-precision machining equipment to ensure machining accuracy and efficiency. Through precise positioning and clamping, they are guaranteed not to shift or deform during machining.

[0046] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the present invention.
[0047] See also Figures 1 and 2 , Figure 1 It is a schematic diagram of the overall structure of the new vertical machining center tooling. Figure 2 yes Figure 1 A longitudinal sectional view of the tooling structure of a vertical machining center is shown.
[0048] As shown in the figure: The present invention provides a vertical machining center tooling 10, which includes a base plate 11, multiple cylinders 12, multiple swinging top blocks 13, multiple positioning blocks 14, and multiple pressure blocks 15. The precise design of each component enables rapid positioning and clamping of the workpiece. Among them, the base plate 11 serves as the foundation of the tooling and firmly supports the entire structure. Multiple cylinders 12 are evenly distributed below the base plate 11 and fixed to the base plate 11. A connector 122 is installed on the top of the piston 121 of each cylinder 12 for transmitting power. In one embodiment, each cylinder 12 is specifically fixed to the base plate 11 through a cylinder seat. Multiple swinging top blocks 13 are evenly distributed above the base plate 11. Each swinging top block 13 is connected to the corresponding cylinder 12 through the connector 122 and moves up and down with the expansion and contraction of the cylinder 12. In addition, a positioning block 14 is provided between two adjacent swinging top blocks 13 for placing the workpiece to be processed (not shown in the figure). A pressure block 15 is provided on both sides of each positioning block 14. Each pressure block 15 is connected to an adjacent swinging top block 13 and moves synchronously with the connected swinging top block 13. In this embodiment, multiple workpieces to be processed are placed on the positioning blocks 14 respectively. The cylinder 12 drives the swinging top block 13 to move up and down through the connector 122. The swinging top block 13 synchronously drives the pressure blocks 15 on both sides of the positioning block to clamp and fix the workpiece, so as to facilitate the clamping or loosening and removal of the workpiece. The vertical machining center tooling disclosed in this embodiment is cleverly designed to achieve precise positioning and clamping. The pressure blocks on the left and right sides of the positioning block can move relative to each other to adapt to the clamping requirements of different workpieces, while supporting the simultaneous processing of multiple workpieces, significantly improving production efficiency and processing quality.
[0049] In some embodiments, the vertical machining center tool 10 is suitable for machining an electronic fuel injection (EFI) valve body. The EFI valve body is a key component in automobile engines, primarily responsible for accurately injecting fuel into the cylinder. It typically consists of a valve body, a nozzle, and a fuel injection hole. Electromagnetic control controls the valve body's opening and closing, thereby achieving fuel injection. The EFI valve body described above is conventional technology, and only a brief overview of its structure is provided here without further detailed description.
[0050] When machining EFI valve bodies on a vertical machining center, this vertical machining center tooling 10 ensures machining accuracy and efficiency. Specifically, the entire EFI valve body or its individual components are placed on the positioning block 14 as the workpiece to be machined. Through precise positioning and clamping, the EFI valve body is prevented from displacement or deformation during machining. Furthermore, multiple workpieces can be machined simultaneously to meet practical application requirements.
[0051] In one embodiment, further reference is made to Figure 1 、 Figure 2As shown in FIG, each swinging top block 13 has a trapezoidal structure, including an upper bottom side 131, a lower bottom side 132, and two inclined surfaces 133. The length of the upper bottom side 131 is shorter than that of the lower bottom side 132. Correspondingly, each pressing block 15 has a T-shaped structure, which is engaged with the two inclined surfaces 133 of the corresponding swinging top block 13.
[0052] In addition, further reference Figure 2 As shown in , the bottom of each pressing block 15 is configured to be in the shape of a barb, and the barb 151 is bent toward the adjacent swing top block 13 , and the front end of the barb 151 is located below the lower bottom edge 132 of the swing top block 13 .
[0053] Specifically, when the workpiece needs to be supported, the positioning block 14 is used to place the workpiece. When the cylinder 12 applies pressure, the piston 121 extends out of the cylinder and drives the swinging top block 13 to move upward through the connector 122. The two side surfaces 133 and the upper bottom edge 131 of the swinging top block 13 push the upper parts of the T-shaped structures of the pressure blocks 15 on both sides of the positioning block 14 toward the inner side of the positioning block 14 to clamp and position the workpiece placed on the positioning block 14. When the workpiece is processed and needs to be removed or the position of the workpiece needs to be adjusted, when the cylinder 12 removes the pressure, the piston 121 retracts into the cylinder and drives the swinging top block 13 to move downward synchronously through the connector 122. The lower bottom edge 132 of the swinging top block 13 presses the bottom barb 151 of the pressure block 15, and the pressure block 151 rotates to loosen the workpiece placed on the positioning block 14, so that the workpiece can be removed or its position can be adjusted.
[0054] In addition, in one embodiment, further reference is made to Figure 1 As shown in the figure, each swing top block 13 is provided with a fixed plate 16 around it to limit the swing top block 13. A gap is left between the swing top block 13 and the fixed plate 16 to ensure that the swing top block is limited while facilitating the movement of the swing top block.
[0055] In addition, in some embodiments, the fixing plate 16 is fastened to the base plate 11 via locating pins and screws, and each pressure block 15 is fastened to the fixing plate 16 via locating pins. The locating pins precisely limit the position of the pressure block 14 on the fixing plate 16, as well as the position of the fixing plate 16 on the base plate 11, ensuring precise alignment and fixation between different parts, thereby improving assembly accuracy. In addition, the fixing plate 16 is fastened to the base plate 11 via locating pins and screws. The combined use of locating pins and screw locking can greatly improve the overall stability of the mechanical system. The locating pins ensure precise alignment and fixation between different parts, while the screw locking prevents loosening by providing additional torque, and the two complement each other. In addition, because the locating pins can simplify the assembly process and help quickly align the workpieces, while the screw locking ensures the stability of the fastening position, this combination can significantly improve assembly efficiency. In harsh working environments such as vibration and impact, the combined use of locating pins and screw locking can ensure the stability and safety of the mechanical system, reducing failures and accidents caused by loosening. This combination can also improve the overall performance and service life of the equipment by adjusting the contact pressure of the bolts and improving the sealing.
[0056] Furthermore, in some embodiments, the positioning block 14 is secured to the base plate 11 by combining a cylindrical pin 171 with a diamond pin 172, achieving precise workpiece positioning and enhanced stability with a two-pin-on-one-side configuration. Specifically, cylindrical pins are known for their high-precision positioning, meeting the high demands of machining in applications requiring precise positioning. By aligning with mating holes, they secure the relative position of workpieces and restrict their movement in certain directions. Diamond pins, with their unique diamond-shaped or square-shaped head design, combine with mating holes to create a fixed boss, further maintaining precise workpiece positioning and restricting movement in a single direction, resulting in even higher positioning accuracy. These pins are suitable for applications requiring high-precision positioning, such as electronic fuel injection valve bodies. Furthermore, the flat bottom surface of the diamond pins ensures stable positioning, preventing workpiece displacement during machining and contributing to improved machining accuracy and quality. Furthermore, the self-locking effect of the diamond pins—when subjected to external forces, the diamond head of the diamond pins rubs against the mating holes, generating a friction torque that further enhances the securing effect. Although the cylindrical pin does not directly provide a self-locking effect, its stable structure and matching with the matching hole make the relative position fixation between the workpieces more reliable.
[0057] In addition, further reference Figure 1 、 Figure 2 As shown in the figure, since the positioning block 14 is arranged between the two adjacent swing top blocks 13, there is no adjacent positioning block on the outside of the two swing top blocks on both sides. Therefore, the pressure block 15 is not set on the outward side of the two swing top blocks 13 on both sides, and only a limiting block 161 for limiting and fixing is set, for example, it is directly set as a positioning pin for limiting.
[0058] In summary, the disclosed vertical machining center fixture is suitable for EFI valve bodies. The workpiece is positioned on a positioning block using two pins on one side. Pressure is applied to the cylinder, which pushes upward, and the connector, swinging block, and pressure block clamp the workpiece, thus achieving positioning and clamping prior to machining in the machining center. After the connector retracts, the swinging block, while limited by the fixed plate, allows for some play but still retracts with the connector and the cylinder. Furthermore, because the pressure blocks are designed with barbs, the swinging block presses against the barbs on the left and right pressure blocks, allowing them to rotate and loosen the workpiece, thus achieving precise positioning and clamping. Furthermore, each positioning block in this fixture can hold a workpiece, allowing multiple workpieces to be quickly placed and processed simultaneously. After processing is complete, the workpiece can be quickly removed and a new blank inserted for the next machining cycle. This vertical machining center fixture features an ingenious design. The pressure blocks on the left and right sides of the positioning block can move relative to each other to accommodate the clamping requirements of different workpieces, supporting the simultaneous processing of multiple workpieces, significantly improving production efficiency and processing quality.
