[0002] In modern manufacturing, a single production line often needs to be compatible with heavy parts of various specifications. However, there are two problems: First, when machining heavy parts on multiple sides, multiple clamping is required, which can easily lead to the offset of the positioning reference and the cumulative error exceeding the accuracy requirements. Second, traditional special tooling is only suitable for a single part, and the entire part needs to be replaced when changing models. This is not only time-consuming, but also costs hundreds of thousands of yuan for a set of special tooling, which significantly increases production costs and affects production efficiency. Utility Model Content

[0005] By adopting the above technical solution: sliding is achieved through T-shaped guide rail grooves, the tooling worktable provides the installation base, and the limiting ear plate cooperates to lock, forming a sliding and adjustable tooling table structure, providing a moving base for part positioning and enhancing the flexibility of tooling.

[0006] Preferably, the T-shaped guide rail groove has a T-shaped structure, and the two horizontally distributed locking screw holes correspond to the positions of the adjusting threaded holes.

[0007] By adopting the above technical solution: the T-shaped structure ensures stable sliding, the locking screw hole and the adjusting screw hole correspond to facilitate locking, ensure the sliding accuracy of the sliding fixture structure, provide a positional basis for subsequent locking and fixing, and improve the reliability of adjustment.

[0009] By adopting the above technical solution, the base platform is slidably connected to the sliding T-shaped limit guide rail through the T-shaped guide rail groove, which enables the base platform to slide stably within the tooling base plate, thereby ensuring smooth sliding without deviation, guaranteeing the stability and accuracy of the tooling platform position adjustment, and meeting the needs of multi-directional adjustment.

[0010] Preferably, the base plate is connected to the upper end of the tooling base plate by four limiting ear plates, and the four limiting ear plates are respectively connected to four locking bolts through four locking screw holes.

[0011] By adopting the above technical solution: the limiting ear plate is inserted into the tooling base plate for limiting, and the locking bolts are used for connection and fixation, which enhances the stability of the connection between the base platform and the tooling base plate, prevents displacement during operation, and improves the overall load-bearing capacity and safety of the tooling.

[0012] Preferably, one end of each of the four locking bolts passes through the adjusting threaded hole and abuts against the end face of the base.

[0013] By adopting the above technical solution, the locking bolt passes through the adjusting thread hole and abuts against the base. The position of the base can be fixed by compression. This not only quickly and reliably locks the sliding base, but also prevents loosening during processing, ensures the positioning accuracy of the parts, and makes the operation convenient and efficient.

[0014] Preferably, the workpiece positioning structure includes a positioning seat, with connecting bolts threadedly connected to the upper circumference of the positioning seat.

[0019] 2. In this utility model, the positioning seat in the workpiece positioning structure is fixed to the tooling worktable by connecting bolts, which can be easily disassembled and replaced to adapt to the needs of different parts.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-4 This utility model provides a technical solution: A multi-directional tooling for heavy parts includes a tooling base plate 1. The tooling base plate 1 has through-threaded adjustment holes 2 at the middle of its front end and the middle of its rear end. Two locking bolts 3 are threadedly connected to the two adjustment holes 2 respectively. A sliding T-shaped limit guide rail 4 is fixedly connected to the middle of the lower inner wall of the tooling base plate 1. A sliding tooling table structure 5 is slidably connected inside the tooling base plate 1. A workpiece positioning structure 6 is provided at the upper end of the sliding tooling table structure 5.

[0026] In this embodiment, the sliding tooling table structure 5 includes a base 51. A T-shaped guide rail groove 52 is provided in the middle of the lower end of the base 51. A tooling worktable 53 is fixedly connected to the upper end of the base 51. Four fixing screw holes 54 are provided in the upper right part of the tooling worktable 53. Two limiting ear plates 55 are fixedly connected to the front and rear ends of the base 51. Each of the four limiting ear plates 55 has a through locking screw hole 56 at the lower part of the end away from the base 51. The T-shaped guide rail groove 52 has a T-shaped structure and two horizontally distributed locking screw holes 56. The tightening screw holes 56 correspond to the positions of the adjusting threaded holes 2. The base 51 is slidably connected to the tooling base plate 1 through the T-shaped guide rail groove 52 and the sliding T-shaped limit guide rail 4. The base 51 is located inside the tooling base plate 1. The base 51 is inserted into the upper end of the tooling base plate 1 through four limit ear plates 55. The four limit ear plates 55 are respectively threadedly connected to four locking bolts 3 through four locking screw holes 56. One end of the four locking bolts 3 passes through the adjusting threaded holes 2 and abuts against the end face of the base 51.

[0027] The above solution involves sliding the T-shaped guide rail groove 52 of the base plate 51 to the sliding T-shaped limit guide rail 4 of the tooling base plate 1, which can drive the tooling worktable 53 to adjust its position along the guide rail. This allows for multi-directional machining of the part after a single clamping, avoiding multiple clamping operations. After adjustment, the locking screw hole 56 of the limit ear plate 55 is aligned with the adjusting threaded hole 2, and the locking bolt 3 passes through and is tightly abutted against the end face of the base plate 51 for fixation. This reduces the number of clamping operations, avoids positioning datum offset, reduces cumulative error, improves machining accuracy, and makes the operation convenient and efficient.

[0028] In this embodiment, the workpiece positioning structure 6 includes a positioning seat 61. The upper end of the positioning seat 61 is threaded with connecting bolts 62 around its perimeter. A V-shaped positioning fixture block 63 is fixedly connected to the upper middle part of the positioning seat 61. A V-shaped groove 64 is provided in the upper middle part of the V-shaped positioning fixture block 63. A bracket 65 is provided on the outer right side of the positioning seat 61. The lower end of the bracket 65 is fixedly connected to the upper right part of the fixture worktable 53. A threaded sleeve 66 is embedded in the upper middle part of the bracket 65. An adjusting screw 67 is threadedly connected to the upper middle part of the threaded sleeve 66. A pressure plate 68 is fixedly connected to the lower end of the adjusting screw 67. The pressure plate 68 is located directly above the V-shaped groove 64. The positioning seat 61 is threadedly connected to the fixture worktable 53 through four connecting bolts 62 and four fixing screw holes 54. The V-shaped groove 64 is V-shaped.

[0029] With the above solution: the positioning seat 61 is connected to the fixing screw hole 54 of the tooling worktable 53 by the connecting bolt 62, which can be quickly disassembled and replaced. The V-shaped groove 64 of the V-shaped positioning tooling block 63 can adapt to cylindrical parts of different diameters. The adjusting screw 67 drives the clamping plate 68 to clamp the parts through the screw sleeve 66. Therefore, the modular design enables quick replacement of the positioning components. The V-shaped structure is compatible with multiple specifications of parts, so there is no need to replace the entire tooling, shortening the changeover time, reducing the cost of special tooling, reducing production costs, and improving production efficiency.

[0030] It should be noted that this utility model is a multi-directional tooling for heavy parts. In use, firstly, the tooling base plate 1 serves as the basic support. The base 51 of the sliding tooling table structure 5 cooperates with the sliding T-shaped limit guide rail 4 through the T-shaped guide rail groove 52, and can slide and adjust its position along the tooling base plate 1 to meet the multi-face processing requirements of the parts. After adjustment, the locking bolt 3 passes through the adjusting threaded hole 2 and the locking screw hole 56 of the limit ear plate 55 and abuts against the base 51 to achieve a stable lock. In the workpiece positioning structure 6, the positioning seat 61 is connected to the fixing screw hole 54 of the tooling worktable 53 through the connecting bolt 62. The V-shaped slot 64 of the V-shaped positioning tooling block 63 places the parts. Rotating the adjusting screw 67 drives the clamping plate 68 to move down and clamp the parts through the screw sleeve 66. This structure achieves multi-face processing in one clamping through sliding adjustment. The V-shaped slot 64 and the replaceable positioning seat 61 are suitable for parts of various specifications, reducing clamping errors and changeover costs, and improving processing accuracy and efficiency.
