[0019] like Figures 1 to 11The illustrated box-type mechanical tooling includes a length-moving clamping device 1, a length-moving positioning device 2, a width positioning pin 3, a moving clamping device 4, and a width-fixing clamping device 5. The length-moving clamping device and the length-moving positioning device are used to position and clamp the box-type workpiece along its length. The width positioning pin 3 and the fixed clamping device are used to position the box-type workpiece along its width. The moving clamping device clamps the box-type workpiece. The moving clamping device has a sliding groove on which the box-type workpiece is placed. The sliding groove provides a stable support base for the box-type workpiece and guides the adjustment of its width. The length-moving positioning device works in conjunction with the width positioning pin to initially position the box-type workpiece, ensuring that the workpiece does not undergo significant displacement during processing. The length-moving clamping device, the moving clamping device, and the width-fixing clamping device work together to reliably clamp and position the box-type workpiece, ensuring processing accuracy.

[0020] like Figures 1 to 6 The illustrated box-type mechanical tooling includes a length-moving clamping device 1 comprising a moving part and a clamping adjustment part, and a length-moving positioning device 2 comprising a moving part and a positioning part. The length-moving clamping device 1 and the length-moving positioning device 2 are respectively disposed on both sides of the box-type workpiece along its length direction, for preliminary positioning and fixing of the box-type workpiece along its length direction. The length-moving clamping device, length-moving positioning device, and moving clamping device of this invention are equipped with locking components, including bolts and nuts, which achieve locking and fixing through threaded engagement. The locking effect is reliable, and disassembly and adjustment are convenient.

[0021] like Figures 1 to 5 The illustrated box-type mechanical tooling includes a length-moving clamping device 1 comprising a slide groove, a moving block, and a clamping bolt. The moving block cooperates with the slide groove, and the clamping bolt is mounted on the moving block. In this length-moving clamping device, the moving block moves on the slide groove to initially adjust the distance between itself and the box-type workpiece. After adjustment, the moving block is fixed on the slide groove. Then, the distance between itself and the box-type workpiece is further adjusted by adjusting the clamping bolt, thereby clamping the workpiece. A clamping plate is provided between the end face of the clamping bolt and the box-type workpiece.

[0022] like Figures 1 to 6 The illustrated box-type mechanical tooling uses a length-moving clamping device 1 and a length-moving positioning device 2, which achieve length-direction positioning adjustment through a pin-hole engagement. The pin holes are spaced apart along the length direction. This invention utilizes a pin-hole engagement for length-direction positioning adjustment, with multiple pin holes spaced apart along the length direction. This allows for quick and easy movement and fixing of the positioning and clamping mechanism to the corresponding position according to the workpiece length requirements. The operation is simple and efficient, ensuring accurate and rapid length-direction positioning.

[0023] like Figures 1 to 4 , Figure 7 and Figure 8 The illustrated box-type mechanical tooling has a positioning pin hole for placing a width positioning pin 3 on one side of the movable clamping device 4. Movable clamping devices 4 are provided on both sides of the box workpiece in the width direction for clamping the box workpiece in the width direction. The width positioning pin 3 is provided on one side of the box workpiece in the width direction for positioning one side of the box workpiece in the width direction. The movable clamping device 4 includes a slide groove and a clamping part, and the box workpiece is placed on the slide groove. The movable clamping devices of this utility model are arranged on both sides of the box-shaped workpiece in the width direction and symmetrically about the center line in the length direction. After the workpiece is positioned, the four movable clamping devices clamp and fix the workpiece. The sliding grooves of the movable clamping devices are combined with the pressure plates to form a clamping structure in the width direction. This structure not only has higher adaptability and can adapt to box-shaped workpieces of different widths, but also provides a stable clamping force to prevent the workpiece from loosening or shifting during processing. In addition, width positioning pins are provided next to the two movable clamping devices on one side of the width direction. The width positioning pins are used in conjunction with the width fixing and tightening device to position the box-shaped workpiece in the width direction.

[0024] like Figures 1 to 4 , Figure 7 and Figure 8 The illustrated box-type mechanical tooling has three pairs of movable clamping devices 4 and positioning pin holes in the width direction. These three pairs are arranged sequentially in the length direction and in the width direction according to their different distances from the box-type workpiece. In this invention, the movable clamping devices and width positioning pins are paired, and corresponding positioning pin holes are provided next to the movable clamping devices at different positions. Depending on the size of the box-type workpiece, the appropriate movable clamping device and width positioning pin can be selected for positioning and clamping, making it convenient and quick.

[0025] like Figures 1 to 4 , Figure 7 and Figure 8 The illustrated box-type mechanical tooling features a sliding groove of a movable clamping device 4 extending along its width. The movable clamping device 4 can slide along the groove and be fixed at a target position. The clamping part of the movable clamping device 4 uses bolts to clamp the box-type workpiece onto the groove. In this invention, the clamping part can slide on the groove. The bolt passes through the clamping part and engages with a nut, which is positioned below the groove. As the clamping part moves along the groove, the nut moves on the other side of the groove. Simultaneously, the outer circumference of the nut is cut with a straight edge to prevent the bolt from rotating. When the clamping part is in position, rotating the bolt, through the engagement of the bolt and nut, clamping of the box-type workpiece is achieved, which is convenient and quick.

[0026] like Figures 1 to 4 , Figure 9 The illustrated box-type mechanical tooling includes a width-fixing and tightening device 5 located on the opposite side of the box-type workpiece's width direction. This device has a clamping part for pressing the workpiece. The clamping part of the width-fixing and tightening device 5 is an adjusting bolt. The width-fixing and tightening device of this invention is located on one side of the box-type workpiece's width direction and in the middle position. It works in conjunction with two width positioning pins on the other side to effectively position and fix the box-type workpiece in the width direction. Both the width positioning pins and the width-fixing and tightening device are detachable, allowing for quick replacement of suitable components according to workpiece size differences without modifying the main structure of the tooling, further improving the tooling's versatility and ease of use.

[0027] like Figures 1 to 11 The box-type mechanical tooling shown has wear-resistant coatings on the sliding contact surfaces of the length moving clamping device 1, the length moving positioning device 2, and the moving clamping device 4.

[0028] The following is the method of using a box-shaped mechanical tooling of this utility model: 1. Based on the dimensions of the box-shaped workpiece to be processed, select and install the appropriate width positioning pin and width fixing clamping device to ensure that they are compatible with the width of the workpiece. 2. Place the box-shaped workpiece on the slide groove of the movable clamping device, slide and adjust the position of the length moving positioning device to match the positioning requirements in the length direction of the workpiece, fix the length moving positioning device by means of pin hole engagement, and at the same time use the width positioning pin to perform preliminary positioning of the workpiece in the width direction, thus completing the preliminary positioning operation of the workpiece. 3. Adjust the position of the sliding adjustment length moving clamping device and the moving clamping device so that they are respectively attached to the parts to be clamped in the length and width directions of the workpiece. Fix the length moving clamping device and the moving clamping device with locking components (bolts and nuts). Then, clamp the workpiece from the other side of the width direction with the width fixing clamping device to achieve full clamping and positioning of the workpiece. 4. When processing box-shaped workpieces of different sizes, loosen the locking assembly, slide and adjust the position of the length moving clamping device, the length moving positioning device, and the moving clamping device, or replace the width positioning pin and the width fixing clamping device with the appropriate size, and repeat the above steps to complete the positioning and clamping of the new workpiece.
