Description
Technical field
The utility model belongs to technical field of mechanical processing, is related to a kind of truning fixture, especially a kind of cylindrical turning dress
It sets.
Background technique
Matrix is the important part on steel tube expansion, and shape is cuboid, and top is arc surface, and lower section is plane, mould
Piece is usually used cooperatively with skewback, and skewback is fitted in cone by inclined-plane；When work, by the axial movement of cone, so that
Skewback is moved along cone inclined-plane, is driven matrix to move radially, is expanded using the arc surface of matrix to steel pipe inner wall, to make
Steel pipe reaches the cylindricity of requirement；For the cylindricity requirement for guaranteeing steel pipe, the excircle dimension coherence request of each matrix is very
Height, since every pair of matrix is all made of eight to 12 matrixs, if can also complete to process using machining center programming, still
Efficiency is lower, occupies numerically-controlled machine tool, and higher cost is improved processing efficiency, can be realized using turnery processing to save processing cost
This purpose is also easier to guarantee excircle dimension consistency.
Matrix Excircle machining need to be realized by tooling, carry out Fixture Design according to part time job state；Due to steel pipe
Specification is more and size has big difference, and in line with the principle of save the cost, should not make too many tooling；Therefore to similar specification
Using a set of tooling, different cushion blocks is needed to change only to realize processing；Through being ground, flatness is higher for the bottom surface of matrix, can be used as
Benchmark, and bottom surface can be positioned there are three seam allowance, devise structurally reasonable dress simple, cost is relatively low using this structure
Set the turnery processing to realize this part.
Utility model content
The technical problems to be solved in the utility model is in view of the deficiencies of the prior art, to propose that one kind can be on center lathe
The cylindrical turning device used.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of cylindrical turning device packet
Cone is included, the both ends of cone are respectively arranged with mandrel and closure plate；It is provided with T-slot in cone, T-type item is provided in T-slot；Cone
Taper liner block is combined on external surface, taper liner block is connected by T-type item with cone；Taper liner block is provided with matrix on outer surface,
It is provided with backing plate between taper liner block and matrix, taper liner block is connected by round key through backing plate and flat key with matrix；Taper liner block
One end close to closure plate is provided with positioning disc；Keyway is arranged in taper liner block lower inclined plane, and round seam allowance is arranged in plane on taper liner block, tiltedly
Setting positioning round key on cushion block.
Preferably, round key two sides are symmetrically arranged with a pair of flat key.
Preferably, taper liner block is equipped with the beveled keyway matched with T-type item close to the side of cone.
Compared with prior art, the utility model has the following beneficial effects: the utility model sufficiently combines the knot of matrix itself
Structure feature only needs to change intermediate correspondence for the matrix of different size using the representative instance that center lathe carries out processed in batches
Backing plate, it is reliable that backing plate top and bottom are respectively provided with positioning spigot positioning, easy for installation；The utility model changes traditional single-piece and adds
The mode of work, Expanding design thinking can process the higher outer circle of precision.

Specific embodiment
A kind of cylindrical turning device, as shown in Figure 1 and Figure 2, including cone 3, the both ends of cone 3 are respectively arranged with 1 He of mandrel
Closure plate 14；It is provided with T-slot in cone 3, T-type item 5 is provided in T-slot；Cone is combined with taper liner block 7, taper liner on 3 outer surface
Block 7 is connected by T-type item 5 with cone 3；It is provided with matrix 9 on 7 outer surface of taper liner block, is arranged between taper liner block 7 and matrix 9
There is a backing plate 12, taper liner block 7 is connected by round key 8 through backing plate 12 and flat key 11 with matrix 9；Taper liner block 7 is close to closure plate 14
One end be provided with positioning disc 13；Keyway is arranged in 7 lower inclined plane of taper liner block, and round seam allowance, taper liner block is arranged in plane on taper liner block 7
The round key of positioning is set on 7；8 two sides of round key are symmetrically arranged with a pair of flat key 11；Taper liner block 7 is equipped with close to the side of cone 3 and T
The beveled keyway that profile bar 5 matches.
Mandrel 1 and closure plate 14 are respectively placed in 3 or so stomidium of cone, are fixed on lathe, then T-type item 5 is placed in T-type
In slot, T-type item 5 is caught in the beveled keyway on taper liner block 7, screw connection not tighten first, positioning disc 13 is placed in taper liner
7 right side of block connects tight each skewback with screw, tight seamless between the two with clearance gauge inspection, by screw-driving, then will pad
Plate 12 is placed in plane on taper liner block 7, is connected by a round key 8 and two flat keys 11, matrix 9 is finally placed in plane on backing plate 12,
It connects, is processed after confirmation is suitable, until reaching requirement yet by a round key 8 and two flat keys 11.
