Description

Technical Field

[0001] The utility model relates to the technical field of boring machine processing, in particular to a large-diameter deep hole drilling component for a boring machine. Background Art

[0002] Boring machines often use cutting components to bore workpieces. When performing large-diameter deep hole processing, multi-blade rough boring cutters are often used for boring. However, when adjusting the cutting size of the multi-blade rough boring cutter, the cutting sizes of multiple blades need to be adjusted and locked one by one. Adjusting the cutting sizes of the blades one by one will cause adjustment errors between each blade and the center. When performing precise boring processing on the workpiece, the boring hole size will be offset to a certain extent. In the adjustment process, it is necessary to press the locating seat with one hand and tighten the bolts with the other hand. When tightening the bolts, the locating seat is prone to offset, making adjustment and use more troublesome. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large-diameter deep hole drilling assembly for a boring machine, comprising a tool holder and a boring tool body, both sides of the top of the boring tool body are slidably connected to a first positioning seat and a second positioning seat, the tops of the first positioning seat and the second positioning seat are bolted to the tool holder, a transmission magazine is fixedly connected at the middle position of the top of the boring tool body, the center position of the transmission magazine is rotatably connected to the transmission shaft, the transmission shaft is fixedly connected to a helical gear near the top position, the transmission shaft is fixedly connected to a gear near the bottom end of the helical gear, the transmission magazine is rotatably connected to a worm gear on the side near the helical gear, the first positioning seat is fixedly connected to a first rack on one lateral side, the second positioning seat is fixedly connected to a second rack on one lateral side, and the middle position of the bottom ends of the first rack and the second rack are fixedly connected to a limiting slider.

[0005] Preferably, an end of the worm away from the transmission compartment is fixedly connected to an adjusting disk.

[0006] Preferably, symmetrically arranged limiting sliding grooves are provided on both sides of the top end of the boring tool body.

[0007] Preferably, a scale is provided on the top of the boring tool body on one side opposite to the first positioning seat and the second positioning seat.

[0008] Preferably, the worm is meshedly connected to the helical gear, and the limiting slider is slidably connected to the limiting sliding groove.

[0009] Preferably, the first rack and the second rack are meshed with gears.

[0010] Compared with the existing technology, the beneficial effect of the present invention is that only by rotating the adjusting disk, the first positioning seat and the second positioning seat can be driven to adjust the cutting size of the blade at the same time, avoiding cutting errors caused by adjusting the blades one by one. At the same time, when tightening the bolts, the positioning seat will not be offset due to touch and external force, which facilitates the tightening of the bolts and is more convenient to use.
