Description
Technical field
This utility model relates to field of machining, is specifically related to a kind of boring grab.
Background technology
Spiral surface part is a kind of part of the heating compound die of Aero-Space isolating pad production and processing, can be at height
Temperature, high pressure environment in work, its service life is low；Owing to the development of China's aviation industry is swift and violent, cause such spiral surface
The demand of part increases, and directly makes it need high-volume to process.
For ensureing production efficiency and the crudy of this spiral surface part, devise the boring grab in this patent, with
Can be accurately positioned, fast and reliable carry out the processing of thread Pilot hole on spiral surface part, and ensure the life of spiral surface part
Produce efficiency and crudy.
Utility model content
This utility model is intended to provide a kind of boring grab, to realize being accurately positioned, fast and reliable carry out spiral surface
The processing of thread Pilot hole on part.
A kind of boring grab in this programme, including base, described base is fixedly connected with side by side spitting drill template and
Latch segment, described spitting drill template is fixedly connected with at least one pair of slide rail, in slide rail on slidably connect clamping stake, described folder
Hold and on the front end face of stake, offer the first V-shaped groove, described latch segment offers the second V-shaped groove, the notch of the first V-shaped groove and
The notch of two V-shaped grooves is oppositely arranged, and described spitting drill template offers through hole, and through hole female thread connects screw, screw with
The rear end face of clamping stake is rotationally connected；Offer on described latch segment for the drill jig sleeve of boring on spiral surface part.
The operation principle of this programme: by rotate screw, screw through hole complete advance or retreat, and then promote or
Pull clamping stake advance or retreat so that the first V-shaped groove near or away from the second V-shaped groove, and to spiral surface part produce
Life is fixing or unclamps, and owing to the surface of the first V-shaped groove and the second V-shaped groove and spiral surface part is point cantact, increases folder
The pressure on the surface of tool and spiral surface part, and then make spiral surface part more stable with contacting of fixture；By boring
The surface of spiral surface part can be processed by die sleeve.
The beneficial effect of this programme: use this fixture, can by the close of the first V-shaped groove and the second V-shaped groove or away from,
Completing spiral surface part fixing or unclamping on fixture rapidly, recycling drill jig sleeve can be to the table of spiral surface part
Face is processed, it is to avoid in the appearance of the slippery surface situation of spiral surface part, improve the precision of processing.
Further, described latch segment offers the pin-and-hole for fixing spiral surface part, in pin-and-hole, is socketed with location
Pin.Increase the surface of spiral surface part and the stability of fixture part, it is to avoid when spiral surface part is processed, spiral
Swinging and causing the decline of machining accuracy occur in profile part, causes the processing failure of spiral surface part.
Further, on described screw, pin connection has the handle for rotating screw.Screw is increased by arranging handle
Surface area, and then increase the point of application between screw and palm, in order to rotate screw and realize clamping advance or the retrogressing of stake.
Further, circular groove is all offered at the bottom tip of described first V-shaped groove and the second V-shaped groove.Alleviate the whole of fixture
While body weight, also reduce the material consumption in fixture manufacturing process.
Accompanying drawing explanation
Fig. 1 is the overall structure figure of a kind of boring grab of this utility model.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: base 1, spitting drill template 2, handle 3, spline pin 4, screw 5, clamping
Stake 6, drill jig sleeve 7, alignment pin 8, spiral surface part 9, trip bolt 10, slide rail 11.
Embodiment is the most as shown in Figure 1: a kind of boring grab includes iron base 1, on base 1 the most also
Row's trip bolt 10 connects spitting drill template 2 and clamping stake 6, and spitting drill template 2 is vertically connected with a pair slide rail 11, this slide rail
Slidably connect clamping stake 6 in 11, the front end face of clamping stake 6 offers the first V-shaped groove, clamping stake 6 offers the 2nd V
Shape groove, the notch of the first V-shaped groove and the second V-shaped groove is relative, and on the groove face of the first V-shaped groove and the second V-shaped groove, erosion has anti-skidding
Stricture of vagina, all offers circular groove at the bottom tip of the first V-shaped groove and the second V-shaped groove simultaneously.
Offering through hole in spitting drill template 2, through hole female thread connects screw 5, by spline pin on the end of screw 5
4 are connected to rotate the handle 3 of screw 5, and the surface of handle 3 is provided with lines, offers circle on the rear end face of clamping stake simultaneously
Groove, is rotatably connected to fixing post in circular groove, the top of screw 5 is fixing with fixing post to be connected.
Clamping stake 6 on offer on spiral surface part 9 boring drill jig sleeve 7, clamping stake 6 on offer for
The pin-and-hole of fixing spiral surface part 9, is socketed with alignment pin 8 in pin-and-hole, the axis of this alignment pin 8 and the axis of drill jig sleeve 7
