Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustment mechanism technology, and in particular to a milling depth adjustment mechanism. Background Technology
[0002] Milling uses a milling cutter as a cutting tool. Through the rotational motion of the milling cutter and the feed motion of the workpiece, the cutting edge on the milling cutter cuts the workpiece, thereby removing excess material and giving the workpiece the desired shape, size and surface quality.
[0003] During milling, each tooth of the milling cutter is equivalent to an independent cutting tool, which cuts the workpiece in sequence. When the cutting teeth enter and exit the workpiece, cutting force and cutting heat are generated. The cutting force and cutting heat during the milling process will cause residual stress on the surface of the workpiece. Residual tensile stress will cause cracks on the surface of the workpiece and reduce the fatigue strength of the workpiece. Residual compressive stress will affect the dimensional stability of the workpiece. Therefore, this application proposes a milling depth adjustment mechanism. Utility Model Content

A cooling mechanism is provided on the mounting plate 2 to uniformly dissipate heat from the milled product on the base plate 1.
[0028] like Figure 2 As shown, the cooling mechanism includes a compressor 8 fixedly mounted on a mounting plate 2. A connecting pipe 9 is fixedly mounted on one side of the compressor 8. A track plate 12 is fixedly mounted on one side of the bottom of the mounting plate 2. A sliding groove is formed in the track plate 12, and a slider 15 is slidably mounted in the groove. A reciprocating screw 14 is rotatably mounted in the track plate 12 and is threadedly connected to the slider 15. A guide cavity 11 is fixedly mounted on one side of the slider 15. The guide cavity 11 is hollow and inclined. Multiple nozzles 16 are fixedly mounted on the guide cavity 11. One end of the connecting pipe 9 is connected to... The guide cavity 11 is connected. When milling, the compressor 8 and motor 13 are started. The compressor 8 draws the cooled air into the guide cavity 11 from the connecting pipe 9, and then sprays it out from the nozzle 16 on one side of the guide cavity 11. The output shaft of the motor 13 drives the reciprocating screw 14 to rotate. The reciprocating screw 14 drives the slider 15 to make horizontal reciprocating motion on the track plate 12. Together with the gas sprayed from the nozzle 16, it can uniformly cool the milling process and the milled product, eliminate residual stress, and improve product quality. The base plate 1 is equipped with an adjustment mechanism to adjust the descent height of the mounting plate 2 in stages.
[0029] like Figure 3As shown, the adjusting mechanism includes a threaded rod 5 fixedly mounted on the base plate 1. A first sleeve 23 is threaded onto the threaded rod 5. The threaded rod 5 is slidably connected to the mounting plate 2. A first external tooth 21 is provided on the outer side of the first sleeve 23.

Then, the second sleeve 20 is rotated to further control the descent distance of the mounting plate 2. Finally, the third sleeve 6 is rotated to perform high-precision control of the descent distance. The compressor 8 and the motor 13 are started.

With the gas sprayed from the nozzle 16, it can uniformly cool the milling process and the milled product, realizing multi-level adjustment of the milling depth, improving milling accuracy, eliminating residual stress, and improving product quality.
