[0032] The following is combined with Figure 1-2 This application is described in further detail.

[0033] This embodiment discloses a hydraulic tooling for a machining center, referring to Figure 1 , including a mounting base 1, a CNC dividing head 2, a rotary tailstock 3, a bridge plate 4, a clamping mechanism 6 and a workpiece base 7. The mounting base 1 serves as the basis of the entire tooling and can be installed on a machine tool or a machining center. The CNC dividing head 2 and the rotary tailstock 3 are coaxially arranged relative to each other and are both mounted on the mounting base 1. The bridge plate 4 is arranged between the CNC dividing head 2 and the rotary tailstock 3, and both ends of the bridge plate 4 are fixedly connected to the CNC dividing head 2 and the rotary tailstock 3 through a fixed seat 5, so as to realize the rotation of the bridge plate 4. The clamping mechanism 6 is fixed on the bridge plate 4, and the workpiece base 7 is detachably connected to the bridge plate 4 through the clamping mechanism 6.

[0034] In this embodiment, the fixing base 5 includes a base portion 51 and an extension portion 52, and is arranged in an L-shape. The base portion 51 is fixedly connected to the CNC dividing head 2 or the rotary tailstock 3, while the extension portion 52 is parallel to the bridge plate 4 and is detachably connected to the bridge plate 4. The fixing base 5 can further enhance the connection stability between the bridge plate 4 and the CNC dividing head 2 and the rotary tailstock 3. The L-shaped fixing base 5 structure not only ensures a stable connection between the bridge plate 4, the CNC dividing head 2 and the rotary tailstock 3, but also facilitates the installation and removal of the bridge plate 4, thereby improving the ease of use of the tooling.

[0035] The clamping mechanism 6 includes a hydraulic cylinder 61 and a pressure plate 62. The pressure plate 62 is fixedly connected to the hydraulic cylinder 61 to achieve stable clamping of the workpiece base 7. The workpiece base 7 is also provided with a fixing member 71 for fixing the workpiece. The fixing member 71 is threadedly connected to the workpiece base 7 to firmly fix the workpiece to the workpiece base 7.

[0036] When using this fixture, first place the workpiece on the workpiece base 7 and fix the workpiece to the workpiece base 7 through the fixing member 71. Then, the hydraulic cylinder 61 drives the pressure plate 62 to clamp the workpiece base 7 on the bridge plate 4. Then, through the cooperation of the CNC dividing head 2 and the rotary tailstock 3, the rotation and precise positioning of the workpiece are achieved. During the processing, the angle and position of the workpiece can be adjusted as needed to achieve comprehensive processing of the workpiece. This fixture structure can quickly complete the clamping and positioning of the workpiece, improve the clamping efficiency and processing accuracy of the workpiece, and effectively solve the problems of cumbersome clamping and large repeated positioning errors in the existing technology.

[0037] In order to ensure the clamping accuracy of the workpiece base 7, the workpiece base 7 is further provided with a positioning hole 72, and a positioning pin is inserted into the positioning hole 72. Through the cooperation of the positioning pin and the positioning hole 72, the positioning accuracy of the workpiece base 7 can be further increased, thereby improving the processing accuracy of the workpiece.

[0038] In addition, positioning ribs 76 are provided at both ends of the workpiece base 7. The positioning ribs 76 protrude from the surface of the workpiece base 7, and the positioning ribs 76 can cooperate with the positioning grooves 621 opened on the pressure plate 62, effectively improving the stability of the cooperation between the workpiece base 7 and the pressure plate 62.

[0039] Further, refer to Figure 2 To enhance the versatility of the workpiece base 7, a workpiece support 8 is provided. This support 8 has a triangular mounting slot 81, and the workpiece base 7 has a protrusion 73 that mates with this slot 81. Protrusion 73 also has inlay slots 74 on either side, and the workpiece support 8 has inlay blocks 82 that mate with these slots 74. The workpiece support 8 and the workpiece base 7 are connected by a fixing member 71.

[0040] The workpiece support 8 can further enhance the stability of the workpiece during machining. The cooperation between the triangular mounting groove 81 and the protrusion 73, as well as the cooperation between the embedding groove 74 and the embedding block 82, makes the connection between the workpiece support 8 and the workpiece base 7 more stable, thereby ensuring the accuracy and stability of the workpiece during machining.

[0041] When using the tooling, first insert the locating pin into the locating hole 72 of the workpiece base 7, and then clamp and position the workpiece. The tight fit between the locating pin and the locating hole 72 can make the position of the workpiece base 7 on the bridge plate 4 more accurate, thereby ensuring the accuracy of the workpiece during the processing.

[0042] In order to improve the machining accuracy of the cylindrical structure or circular hole on the workpiece, a reference hole 75 is further provided on the workpiece base 7, which can be used as a reference when machining the hole column.

[0043] In this application, the rotary tailstock 3 uses a hydraulic tailstock. The design and construction of the hydraulic tailstock ensure its stability during operation. This stability is due to its internal structure and material selection, which enables the hydraulic tailstock to remain stable under high-speed and heavy-load operating conditions, reducing vibration and displacement, thereby improving operating accuracy and efficiency. Preferably, the rotary tailstock 3 can also use a servo tailstock according to actual needs.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
