Description

Technical Field

[0001] This application relates to the technical field of fixtures for magnesium alloy sheet processing, and specifically to a workbench for dry milling of magnesium alloys. Background Technique

[0002] As a light metal, magnesium alloy has been widely used in the fields of aerospace, 3C products, automotive manufacturing, etc. due to its low density, high strength, good heat dissipation performance and excellent damping characteristics. Due to these unique advantages of magnesium alloy, its processing technology has also attracted much attention, especially milling. Milling, as a key link in the manufacturing process, is of great significance for improving the processing quality and production efficiency of magnesium alloy products. In traditional magnesium alloy milling, cutting fluid is often used to reduce the processing temperature, lubricate the tool and the workpiece, but this method has problems such as environmental pollution and increased manufacturing costs. Therefore, dry milling technology has emerged and gradually become a trend.

[0003] Dry milling mainly uses high-performance tool materials to reduce the dependence on cutting fluid by optimizing the processing conditions. Since there is no flushing by cutting fluid, there will be more debris scattered around the milling equipment during the milling process. If a traditional workbench is used to fix the magnesium alloy component during dry milling, since the surface of the traditional workbench has a chute for adjusting the fixture, the debris generated during the milling process is extremely easy to accumulate inside the chute, thus causing the blockage of the chute, making the fixture unable to be adjusted normally. At the same time, it is very difficult for the existing workbench to fix the magnesium alloy special-shaped plate component. Utility Model Content

[0004] This application provides a workbench for dry milling of magnesium alloys. During the dry milling process, the generated debris can be conveniently collected together, and the debris at this time will not affect the normal adjustment of the fixture during the milling process. At the same time, this workbench can realize the rapid clamping and positioning of magnesium alloy special-shaped plate components, and can effectively solve the problems in the background technique.

[0024] Specifically, the magnesium alloy plate to be milled is placed on the upper surface of the guide rod 4 18. The magnesium alloy plate is hoisted by hoisting equipment during loading. After loading is completed, the adjusting screw 12 is rotated so that the slide 2 4 set at the end of the adjusting screw 12 can clamp the magnesium alloy plate.

[0025] More specifically, for a magnesium alloy plate with regular shape, it can be directly hoisted onto the upper surface of the second sliding table 4, and then the position of the second sliding table 4 is adjusted so that the first thrust screw 5 arranged on its upper surface can tightly press the workpiece.

[0026] The flow guiding groove 6 is connected with a first guide rod 3 through struts 15 arranged on the left and right sides in the middle of its upper surface. The first guide rod 3 and the fourth guide rod 18 are vertically and cross - arranged. Both the front and rear ends of the outer side surface of the first guide rod 3 are slidably connected with a first sliding table 2, and a second thrust screw 17 is installed on the upper surface of the first sliding table 2.

[0027] Specifically, the first sliding table 2 is pushed along the first guide rod 3 so that the second thrust screw 17 on the first sliding table 2 can closely adhere to the workpiece, and then the position of the first sliding table 2 is fixed.

[0028] More specifically, the second thrust screw 17 is a tapered rod with a larger upper part and a smaller lower part. After the position of the first sliding table 2 is fixed, the second thrust screw 17 is rotated so that the second thrust screw 17 can tightly press the outer surface of the workpiece to be processed.

[0029] Further, the flow guiding groove 6 is arranged to be inclined forward.

[0030] Specifically, the flow guiding groove 6 arranged to be inclined forward is convenient for cleaning debris.

The protective cover 13 is slidably connected with the through - hole arranged on the U - shaped support 1, and the end of the protective cover 13 is fixed on the outer side surface of the second sliding table 4.

[0035] Specifically, the setting of the protective cover 13 can effectively prevent debris generated during the machining process from falling onto the thread of the position - adjusting screw 12, thus affecting the normal rotation of the position - adjusting screw 12.

[0036] Further, the first sliding table 2 is fixed on the first guide rod 3 through a stud - head screw 14.

[0037] Specifically, the leading stud two 14 passes through the threaded hole provided on the first sliding table 2 and its end presses tightly against the outer surface of the first guide rod 3, thereby fixing the position of the first sliding table 2.

[0038] Furthermore, a plurality of internal threaded holes 16 are linearly and evenly distributed on the upper surface of the first sliding table 2, and the second thrust screw 17 is installed on the internal threaded holes 16.

[0039] Specifically, according to the shape of the magnesium alloy plate to be fixed, the installation position and the number of the second thrust screws 17 on the first sliding table 2 can be adjusted, so that the second thrust screws 17 can clamp the magnesium alloy plate in the front and back directions.

[0040] During use: The magnesium alloy plate to be milled is hoisted onto the upper surface of the fourth guide rod 18. After the feeding is completed, the positioning screw 12 is rotated so that the second sliding table 4 provided at the end of the positioning screw 12 can clamp the left and right sides of the magnesium alloy plate.

[0041] Then, the first sliding table 2 is pushed along the first guide rod 3, so that the second thrust screws 17 on the first sliding table 2 can closely adhere to the workpiece. Subsequently, the position of the first sliding table 2 is fixed, and the second thrust screws 17 are rotated downward so that the second thrust screws 17 can tightly press against the outer surface of the workpiece to be machined, thereby realizing the front and back position fixation of the workpiece.

[0042] The metal chips produced during the machining process of the workpiece can fall into the diversion groove 6, which facilitates the collection of the chips.
