Description

Technical Field

[0001] The utility model relates to an alloy boring tool, in particular to an alloy boring tool with adjustable boring depth, belonging to the technical field of alloy boring tools. Background Art

[0002] Boring cutters are important and indispensable tools in precision hole processing. The precision of the processed holes can reach IT6 level, and the surface roughness can reach 'Ra0.8~1.6μm. Common types include threaded fine-tuning boring cutters, eccentric fine-tuning boring cutters, slide-type double-edged boring cutters and floating boring cutters. These fine-tuning boring cutters have their own characteristics and are widely used in actual production. They can be used on boring machines, lathes or milling machines.

[0003] In the prior art, as disclosed in announcement number CN221289553U, an alloy boring tool with adjustable boring depth is first connected to the tool rod through the machine tool equipment, and then the workpiece can be processed. During the processing, when the boring depth of the tool needs to be adjusted, the user loosens the second bolts on both sides so that the second bolts no longer conflict with the surface of the moving rod, and then turns the handle. The rotation of the handle drives the first rotating rod to rotate, and the first rotating rod rotates and then drives the second bevel gear to rotate. The rotation of the second bevel gear drives the first bevel gear to rotate. The rotation of the first bevel gear drives the first screw to rotate. The rotation of the first screw drives the moving rod to move inside the tool rod through the limit of the limit slider, so that the boring depth can be adjusted according to actual milling requirements.

[0004] However, in the implementation of relevant technologies, it was found that the alloy boring tool with adjustable boring depth designed above has the following problems: in the prior art, the length of the tool is adjusted by the cooperation of components such as the second bolt, but in actual use, the tool is in a rotating form and is only resisted by the cooperation of components such as the second bolt. When the torsional force is large, it may become loose, thereby causing the tool to become loose and affecting its use. In view of this, an alloy boring tool with adjustable boring depth is provided to overcome the above defects. Utility Model Content

[0005] The utility model provides an alloy boring tool with adjustable boring depth to solve the problem that the tool may become loose when the torsional force is large, thereby causing the tool to become loose and affecting its use.

[0007] The adjusting mechanism includes a ring, which is slidably connected to the outer wall of the sleeve, and a slider is fixed to the outer wall of the sleeve corresponding to the slide groove. The slider is inserted into the interior of the sleeve and is fixed with a fixed block, and a limiting hole is provided inside the fixed block. A limiting block is provided inside the limiting hole, and a connecting disk is fixed to the bottom end of the limiting block.

[0008] As a further solution of the present invention: a sliding structure is formed between the collar and the sleeve, and a sliding structure is formed between the sleeve and the slider through the sliding groove.

[0009] As a further solution of the present invention: an upper connecting ring is sleeved above the outer ring of the sleeve, and a lower connecting ring is sleeved below the outer ring of the sleeve.

[0010] As a further solution of the present invention: upper connecting frames are fixed on both sides of the outer wall of the upper connecting ring, and lower connecting frames are fixed below both sides of the outer wall of the sleeve.
