Abstract
The invention relates to a boring mechanism capable of realizing fine-adjustment feeding, which comprises boring rods, a fastening sleeve and a positioning block, and is characterized in that: a boring rod A is a hollow shaft; a regulating rod is arranged in the hollow shaft; the two ends of the regulating rod have a bearing I and a bearing II; the boring rod A extends from one side of the regulating rod; the top end of the boring rod A is provided with a dial scale and a handle; a gear is arranged in the fastening sleeve on the other side of the regulating rod; the boring rod A and a boring rod B are connected into a whole by the fastening sleeve; the boring rod A and the boring rod B are axially positioned by a positioning block; a square hole is formed on the fastening sleeve; a turning tool is arranged below the square hole; a bearing positioning hole is arranged on the inner side of the square hole; the upper part of the square hole is provided with a regulating main shaft; bearings are arranged on the two sides of the regulating main shaft; the two bearings are arranged in the positioning block and the fastening sleeve respectively; the regulating main shaft is provided with a gear, which forms a pair with the gear in the fastening sleeve, between the two bearings; and one side of the regulating main shaft is provided with external threads which are meshed with the internal threads on the turning tool. The boring mechanism has the advantages of accurately regulating turning tool, machining to preset size and improving machining efficiency.
Description
Technical field
The present invention relates to a kind of boring mechanism that realizes finely tuning feed.
Background technology
Boring bar is generally used in a series of circular hole processing of opening in the existing double entry pump pump housing on the face, and boring bar relies on special-purpose power-equipment that axially-movable is provided and rotatablely moves, and on boring bar, boring bar drives the lathe tool cutting to lathe tool with screw in compression.After the lathe tool cutting at one time is finished, carry out size adjustment, but can not realize size adjustment accurately, working (machining) efficiency low (with reference to Fig. 1).Therefore demand urgently developing a kind of can be in the boring process, the device that can accurately regulate lathe tool feed size is beneficial to open in the double entry pump pump housing the accurate processing of a series of circular holes on the face.
Summary of the invention:
The objective of the invention is to solve in the prior art lathe tool and tightly on boring bar, can't carry out size with screw and accurately regulate existing problem, a kind of boring mechanism that realizes finely tuning feed is provided.The present invention designs a kind of boring mechanism that realizes finely tuning feed, comprise the boring bar first, boring bar second, adapter sleeve, locating piece, it is characterized in that:, the boring bar first is a hollow shaft, in adjusting rod is housed, there is each bearing at the adjusting rod two ends, adjusting rod one side is stretched out the boring bar first, dial and handle are equipped with in its top, and the adjusting rod opposite side is positioned at adapter sleeve a gear, boring bar first are housed, boring bar second connects in aggregates by adapter sleeve with adapter sleeve, boring bar first and boring bar second are come axial location with locating piece, have square opening on the adapter sleeve, under the square opening lathe tool is arranged, there is the bearing locating hole square opening inboard, the adjusting main shaft is arranged at square opening top, regulate the main shaft both sides bearing is housed, two bearings is respectively charged in locating piece and the adapter sleeve, regulates main shaft and is being positioned at two bearings, between gear is housed, the gear that this gear and adjusting rod one side are positioned at adapter sleeve forms a pair of gear pair, and regulating main shaft one side has external screw thread, stretches into adapter sleeve internal thread interior and on the interior lathe tool of square hole and is meshed.Advantage of the present invention is to regulate lathe tool exactly, is worked into predetermined size, improves working (machining) efficiency.
Description of drawings:
Fig. 1 is the prior art constructions schematic diagram,
Fig. 2 is a structural representation of the present invention,
Below in conjunction with accompanying drawing and construction embodiment the present invention is made detailed operation instruction.
The specific embodiment:
Comprise boring bar first 1 among the figure, boring bar second 2, adapter sleeve 3, locating piece 4, it is characterized in that:, boring bar first 1 is a hollow shaft, in adjusting rod 5 is housed, there are bearing 6 and bearing 7 in adjusting rod 5 two ends, adjusting rod 5 one sides are stretched out boring bar first 1, dial 8 and handle 9 are equipped with in its top, adjusting rod 5 opposite sides are positioned at adapter sleeve 3 gear 10 are housed, boring bar first 1, boring bar second 2 connects in aggregates by adapter sleeve 3 usefulness adapter sleeves 3, boring bar first 1 and boring bar second 2 usefulness locating pieces 4 come axial location, have square opening 11 on the adapter sleeve 3, lathe tool 12 is arranged under the square opening, there is the bearing locating hole square opening 11 inboards, the main shaft 13 of adjusting is arranged at square opening 11 tops, regulate main shaft 13 both sides bearing 14 and bearing 15 are housed, two bearings 14,15 are respectively charged in locating piece 4 and the adapter sleeve 3, regulate main shaft 13 and be positioned at two bearings 14, gear 16 is housed between 15, the gear 10 that this gear 16 and adjusting rod 5 one sides are positioned at adapter sleeve 3 forms a pair of gear pair, regulating main shaft 13 1 sides has external screw thread 17, stretches into adapter sleeve 3 internal threads 18 interior and on interior 11 lathe tools 12 of square hole and is meshed.
When turning handle, adjusting rod rotates, and the gear that drives the other end rotates, and gear pair rotates, and regulates main shaft and also rotates, and the thread belt motor-car cutter of regulating main shaft moves in square opening.When handle rotated, dial can accurately be measured rotational angle and the moving distance of lathe tool, realizes small adjusting.
