Abstract
Description
Technical Field
[0001] This utility model belongs to the field of clamping and positioning tooling technology, specifically relating to a clamping tooling device for batch milling bevels. Background Technology
[0002] In the field of machining, especially in the manufacturing of metal structural components, beveling is a common and critical process. The quality and precision of the beveling significantly impact subsequent welding processes as well as the strength and stability of the entire structure. Traditional beveling methods typically involve using semi-automatic cutting machines or robots to position and gas-cut individual parts one by one. This approach is not only inefficient but also struggles to guarantee consistency and precision. An excessively large bevel increases heat input during welding, causing overheating of the weld joint and resulting in changes in microstructure and properties, such as coarse grains and decreased toughness. This reduces the strength of the weld joint, affecting weld quality. Increased welding deformation affects the dimensional accuracy and shape of the weldment. An excessively small bevel leads to poor fusion during welding, easily resulting in welding defects such as incomplete penetration and lack of fusion. It also hinders the expulsion of gas and inclusions from the weld, potentially leading to defects such as porosity and slag inclusions. This reduces weld strength and sealing performance, affecting the stability and consistency of weld quality. Furthermore, it easily generates significant residual welding stress, which may affect the performance and fatigue life of the weldment. Utility Model Content

A stack of workpieces 7 is placed on the upper surface of the inclined plate of the angle positioning plate 3. One outer end of the stack of workpieces 7 extends to the outer side of the angle positioning plate 3, and one inner end of the stack of workpieces 7 contacts the vertical section of the fixing frame 2.
[0031] A vertical groove is provided at the upper end of the vertical section of the fixed frame 2.

[0036] The working principle of this utility model is as follows:
[0037] like Figure 1 As shown, when the slope to be processed for workpiece 7 is 45°, loosen the fastening bolt 5, insert the slider 4 into the designated T-slot, and then slide the slider 4 inside the T-slot to fix its position. Then tighten the fastening bolt 5, thus fixing the position of the entire fixing frame 2. Then place a stack of workpieces 7 on the upper end of the inclined plate of the angle positioning plate 3, so that one inner end of the stack of workpieces 7 contacts the vertical section of the fixing frame 2. Then place the pressure rib 8 on the upper end of the stack of workpieces 7, with the plane of the inclined side of the pressure rib 8 contacting the upper end face of the stack of workpieces 7, and the plane of the first right-angle side of the pressure rib 8 contacting the vertical section of the fixing frame 2. Then place the pressure tube 9 on the upper end of the pressure rib 8. Place multiple fixing posts 13 on the milling machine platform 1, so that the uppermost end face of the stack of fixing posts 13 is flush with the upper end face of the pressure tube 9. Then, the pressure plate 10 is placed inside the groove at the upper end of the vertical section of the fixed frame 2, so that one end of the pressure plate 10 contacts the upper end face of the pressure tube 9, and the other end of the pressure plate 10 contacts the uppermost end face of the stack of fixed columns 13. At the same time, the upper end of the lifting screw 11 passes through the working hole on the pressure plate 10. Then, a fastening nut 12 is screwed onto the upper end of the lifting screw 11. Tightening the fastening nut 12 makes the pressure plate 10 in close contact with the pressure tube 9 and the fixed columns 13. The pressure plate 10, through the pressure tube 9 and the pressure rib 8, tightly presses and fixes the stack of workpieces 7 to the upper end of the inclined plate of the angle adjustment plate. At this time, the batch milling of bevels on the stack of workpieces 7 can be performed.
[0038] like Figure 2 As shown, when the bevel angle to be processed on workpiece 7 is not 45°, before placing a stack of workpieces 7, first place an angle adjusting wedge 14 on the upper end of the inclined plate of the angle positioning plate 3, so that the lower end face of the angle adjusting wedge 14 contacts the upper end face of the inclined plate, and one inner end of the angle adjusting wedge 14 contacts the vertical section of the fixing frame 2. Then, place a stack of workpieces 7 on the upper end of the angle adjusting wedge 14. Next, place the pressure ribs 8, pressure tubes 9, fixing columns 13, and pressure plates 10 with different inclinations in sequence according to the above steps. In this way, the stack of workpieces 7 is clamped and fixed, and the angle of the stack of workpieces 7 meets the processing requirements. At this time, the batch milling bevel process can be performed on the stack of workpieces 7.
