[0002] Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. The main motion is usually the rotation of the milling cutter, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc. At present, when processing the drill rod of a rock drill, the milling machine usually needs to fix the drill rod on an inclined fixture so that the chip surface of the drill rod head corresponds to the milling cutter. However, when the fixed fixture of the drill rod is fixed on the workbench of the milling machine, it is usually necessary to manually adjust its inclination angle, resulting in a large error in chip cutting and an increase in the defective rate of the drill rod. To this end, we provide a tooling for processing inclined arc grooves on a common milling machine to solve the above problems. Utility Model Content

The center of the arc-shaped slide groove 11 is arranged to coincide with the rotation point of the first slot block 21, the slider 3 is slidably engaged in the inner cavity of the arc-shaped slide groove 11, the cross-section of the arc-shaped slide groove 11 is arranged in a convex shape, and the slider 3 is matched with the inner cavity of the arc-shaped slide groove 11, and the internal thread of the slider 3 is connected with a bolt 31, and the threaded end of the bolt 31 is pressed against the bottom of the inner wall of the arc-shaped slide groove 11. When the bolt 31 is tightened to press the bottom of the inner cavity of the arc-shaped slide groove 11, the slider 3 can be fixed in the inner cavity of the arc-shaped slide groove 11, thereby fixing the overall angle of the fixing component 2.

[0014] Specifically, the fixing component 2 also includes two connecting rods 23, which are arranged in parallel. The first slot block 21 and the second slot block 22 are fixedly connected by the two connecting rods 23, and the two connecting rods 23 are respectively located on both sides of the V-shaped groove of the first slot block 21 and the second slot block 22, so that the connecting rod 23 can connect and fix the first slot block 21 and the second slot block 22 while avoiding the position of the fixing component 2 to fix the drill rod. A screw rod 24 is fixedly arranged on the top of the connecting rod 23, and a clamping block 25 is arranged between the two screw rods 24. The clamping block 25 movably passes through the outer walls of the two screw rods 24, and the outer walls of the screw rods 24 are threadedly connected with nuts 26. When the drill rod is placed in the V-shaped groove of the first slot block 21 and the second slot block 22, the clamping block 25 can be sleeved on the outer walls of the two screw rods 24, and the nuts 26 are tightened on the screw rods 24, so that the clamping block 25 can clamp and fix the drill rod.

[0015] Specifically, a pointer 32 is fixedly provided on the side wall of the slider 3 facing away from the second slot block 22, and a scale line 12 is processed on the base 1 corresponding to the movement arc of the pointer 32. By setting the pointer 32 and the scale line 12, the staff can intuitively judge the rotation angle of the fixed component 2, thereby facilitating the angle adjustment of the fixed component 2.

[0016] Specifically, a V-shaped groove is provided on the clamping surface of the clamping block 25, and the V-shaped groove corresponds to the V-shaped grooves of the first groove block 21 and the second groove block 22. The design purpose is to increase the fixing surface of the drill rod, thereby making the fixing assembly 2 more stable for fixing the drill rod.

[0017] Specifically, the screw 24 is arranged at the top center position of the connecting rod 23. Its design purpose is to place the clamping block 25 at the center position of the first slot block 21 and the second slot block 22, so as to stably fix the drill rod. A plurality of mounting holes are opened inside the base 1, and the mounting holes can fix the base 1 on the worktable surface of the milling machine.

[0018] Working principle: When processing the drill rod, the base can be bolted to the workbench of the milling machine through the mounting hole, and the inclination angle of the fixed component can be adjusted according to the processing angle of the drill rod bit. First, loosen the bolt to separate the bolt from the arc-shaped slide. At this time, pull the second slot block to rotate with the rotation point of the first slot block, and judge the rotation angle according to the scale line indicated by the pointer. When the rotation angle of the fixed component is consistent with the processing angle of the drill rod bit, tighten the bolt until the arc-shaped slide is pressed tightly. At this time, the fixed component is fixed. The drill rod is fixed, and then the nut is loosened to separate it from the screw and the clamping block is removed. The drill rod is placed in the V-grooves of the first slot block and the second slot block. At the same time, the initial processing point of the drill rod and the drill bit corresponds to the milling cutter. At this time, the clamping block is sleeved on the outer walls of the two screws, and the two nuts are tightened until the clamping block is pressed down to fix the drill rod. At this time, the workbench of the milling machine can be operated to move horizontally, and the drill rod and the drill bit can be beveled under the rotation of the milling cutter. This fixing method replaces the traditional manual fixing tooling, making the processing angle of the drill rod and the drill bit more accurate.
