[0002] In the prior art, workpieces need to be positioned on the machining platform of a milling machine before milling grooves. However, when positioning some special structure workpieces or milling special grooves, it is often difficult to use the clamps on the existing machining platform of the milling machine for positioning. Therefore, positioning fixtures for different structure workpieces have emerged.

[0003] Currently, traditional milling fixtures that can fix workpieces of different sizes often result in parts of the workpiece being suspended in the air when machining long workpieces due to the limited stroke of the milling machine, which seriously affects the accuracy of fixing the workpiece parts.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The lifting mechanism of this application allows the equipment to be adjusted according to the height of the workpiece, thereby achieving stable clamping of workpieces of different sizes. Through the cooperation of the set screw and the lifting screw, the lifting position of the workpiece can be precisely controlled to ensure processing accuracy.

At the same time, it also has the ability to quickly change workpieces. With simple adjustments, it can adapt to workpieces of different shapes and sizes, greatly improving the flexibility and efficiency of production. In addition, the operation is more convenient, enabling operators to quickly and accurately complete the clamping and unloading of workpieces, thereby shortening the production cycle and improving production efficiency.

The set screw 86 passes through one side of the lead screw nut 81 and abuts against the outer wall of the lifting lead screw 83.

[0026] Please see Figure 1 , Figure 3 and Figure 4 The clamping mechanism 9 includes a pad 91, the lower end of which is fixedly connected to the upper end of the support plate 87. A rubber pad 92 is provided on the upper end of the pad 91. A base plate 93 is provided on both sides of the pad 91. Side plates 94 are fixedly connected to the upper ends of the base plates 93. A guide hole 95 is provided in the middle of the base plate 93. A screw 96 is rotatably connected to one side of the upper end of the pad 91. A pressure plate 97 is threaded to the outer wall of the screw 96. A handle 98 is fixedly connected to the upper end of the screw 96. A rubber pad 99 is bonded to the lower end of the pressure plate 97. A slide rod 910 is slidably connected to the other side of the pressure plate 97. The upper end of the pad 91 is bonded to the lower end of the rubber pad 92. Both sides of the pad 91 are fixedly connected to one side of the base plate 93. There are two side plates 94, which are symmetrically arranged on both sides of the upper end of the base plate 93. The screw 96 and the slide rod 910 are of the same length.

[0027] Working principle: First, the lead screw nut 81 cooperates with the lifting lead screw 83. The rotation of the drive rod 85 achieves the vertical movement of the lifting lead screw 83, thus raising and lowering the pad 91. The fixed block 84 facilitates control of the rotation of the lifting lead screw 83, ensuring its stability. The guide rod 6 cooperates with the guide hole 95 to ensure the smooth movement of the pad 91 and the pressure plate 97. The clamping mechanism 9 is used to fix the workpiece. Its structure allows for quick clamping and release of workpieces of different sizes. Through this design, the milling fixture can adapt to various workpiece sizes, improving processing efficiency and accuracy. The lead screw nut 81, which is fixedly connected to the worktable 1 by bolts 82, the lifting lead screw 83 that cooperates with the lead screw nut 81, and the mechanism 9 fixed to the top of the lifting lead screw 83 are all included. The support plate 87 contacts the bottom of the pad 91, the fixing block 84 is fixed to the lower end of the lifting screw 83, and the drive rod 85 passes radially through the fixing block 84. When the drive rod 85 is rotated, the lifting screw 83 can be driven to rotate and move up and down. When the lifting screw 83 rotates and moves up, the support plate 87 pushes the pad 91 upward to support parts with smaller diameters. When the lifting screw 83 rotates and moves down, the pad moves down to support parts with larger diameters. A set screw 86 is provided on the side wall of the screw nut 81, which locks the screw nut 81 and the lifting screw 83. By rotating the drive rod 85, the lifting screw 83 can be moved up and down, thereby driving the support plate 87 and the pad 91. Lifting and lowering: When it is necessary to change the workpiece, the gap between the pad 91 and the workpiece can be adjusted by rotating the set screw 86 to ensure the stable fixation of the workpiece. The height of the pad 91 is adjusted until the lower end of the workpiece contacts the opening on the pad 91, and then the set screw 86 is locked. At this time, the pad 91 supports the workpiece. Then, the pressure plate 97 is installed on the top of the pad 91, and the workpiece is clamped and fixed by the cooperation of the pressure plate 97 and the pad block. The operator only needs to rotate the handle 98, which drives the screw 96 to rotate. At this time, the pressure plate 97 moves up or down along the external thread of the screw 96, and the pressure plate 97 moves stably along the slide rod 910 until the rubber pad 99 contacts the upper end surface of the workpiece. In addition, the lifting mechanism 8 makes the operation easier. Operators can easily adjust the height of the workpiece to adapt to different processing needs. The entire lifting mechanism 8 has a compact structure and is easy to operate, effectively improving the efficiency and accuracy of workpiece clamping. It also achieves stable clamping and precise positioning of the workpiece. The use of rubber pads 92 and 99 not only increases the clamping friction but also protects the workpiece surface from damage. The rotation of the handle 98 adjusts the clamping force of the pressure plate 97 to accommodate workpieces of different sizes and shapes. The sliding setting of the slide rod 910 allows the pressure plate 97 to move within a certain range, increasing the stability of the pressure plate 97 during movement, thus adapting to workpieces of different lengths and greatly improving the flexibility and efficiency of workpiece processing. When it is necessary to adjust the angle of the pad 91...The operator rotates the two guide nuts 7 at the bottom of the guide rod 6 until they are securely fastened to the upper and lower surfaces of the worktable 1. Then, the operator rotates the pad 91 to a suitable angle and tightens the guide nuts 7, which fix the guide rod 6 in place. This achieves multi-angle adjustable functionality, overcoming the limitations of existing technologies and increasing the overall flexibility of the device.
