Abstract
The utility model discloses an adjustable mandrel device used for pipe connecting flange machining. Supporting rings (1) coaxial with a mandrel body (5) are arranged at the two ends of the mandrel body (5), the supporting rings (1) are positioned through bolts (4) in the radial direction and the axial direction and fastened on the mandrel body (5) to be integrally formed, each supporting ring (1) is circumferentially and uniformly provided with a plurality of supporting nails (2), and each supporting nail (2) is positioned through an adjusting nut (3) and fastened onto each supporting ring (1). The mandrel device is installed into a connecting pipe (6), the adjusting nuts (3) are rotated, the supporting nails (2) are moved in the radial direction and abut against the inner wall of the connecting pipe (6) to form shaft-type product components; an axle machining method is adopted on a horizontal lathe, and disposable clamping is achieved to complete turning of flanges at the two ends of the connecting pipe. The adjustable mandrel device can economically, efficiently and precisely machine components of products of the connecting pipe type, and guarantee concentricity requirements for the flanges at the two ends of the connecting pipe.
Description
Technical field
The utility model relate to a kind of for pipe connecting flange processing a kind of radially, the equal adjustable spindle unit of axial dimension.
Technical background
In industrial production, take over the processing of class part two end flanges, need twice and twice above clamping, class part draw ratio is larger when taking over, two end flanges seam concentricity requirement are when high, and processing gets into a difficult position, and conventional processing method can not meet the product quality requirement.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of radially, the equal expansion mandrel device of adjustable pipe connecting flange processing of axial dimension.
In order to solve above-mentioned first technical problem, the expansion mandrel device of the pipe connecting flange processing that the utility model provides, at axle body two ends, be equipped with and this body concentric support ring of described axle, described support ring by bolt radially, axial location be fixed tightly on the axle body and become an integral body, on described support ring, circumferentially evenly be provided with a plurality of support nails, described support nail is located and is fixed tightly on described support ring by adjusting nut.
Described support ring is provided with rectangular channel, the bottom land of described rectangular channel is provided with through hole, described support nail is provided with the rectangle head that an end is the face of cylinder, with described rectangular channel, be slidably matched, the through hole that the double-screw bolt end of described support nail passes the bottom land of described rectangular channel is connected with described adjusting nut.
Adopt the expansion mandrel device for pipe connecting flange processing of technique scheme, by spindle unit adapters of packing into, the rotation adjusting nut, support nail moves radially, and diameter increases, and holds out against nozzle inner wall, formation axis products part; On horizontal lathe, adopt the processing method of axletree, disposable clamping completes takes over two ends flange turning processing.
The utility model advantage is:
1, disposable clamping completes and takes over two ends flange turning processing, economical, efficient, precisely, is particularly useful for and guarantees to take over two end flanges concentricity high requests.
2, radial dimension is adjustable, and axially mounting position size is also adjustable, has versatility.
3, simple to operate, convenient mounting and clamping.
In sum, the disposable clamping of the utility model energy is on horizontal lathe, economical, efficient, and the series products part is taken in processing accurately, and the high concentricity requirement of two end flanges is taken in assurance.
The accompanying drawing explanation
Fig. 1 is spindle unit structure chart of the present utility model.
Fig. 2 is the schematic diagram of installing and using of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, at axle body 5 two ends, be equipped with the support ring 1 concentric with axle body 5, support ring 1 by bolt 4 radially, axial location be fixed tightly on axle body 5 and become an integral body, the axial dimension that support ring 1 spacing is taken over according to product parts is set; On support ring 1, circumferentially evenly be provided with a plurality of rectangular channels 7 that are provided with, in each rectangular channel 7, be provided with a support nail 2, the bottom land of rectangular channel 7 is provided with through hole, and support nail 2 is provided with the rectangle head that an end is the face of cylinder, is slidably matched with rectangular channel 7; The through hole that the double-screw bolt end of support nail 2 passes the bottom land of rectangular channel 7 is connected with adjusting nut 3.
Referring to Fig. 2, the spindle unit product parts of packing into takes over 6, rotation adjusting nut 3, and support nail 2 moves radially, and holds out against to take over 6 inwalls and become an integral body, forms the axis products part; On horizontal lathe, adopt the processing method of axletree, namely clamp axle body 5 one end cylindricals, hold out against axle body 5 other end centre bores, disposable clamping completes takes over two ends flange turning processing.
