Description

A kind of special fixture processing connection steel band assembly
Technical field
The utility model relates to field of machining, is specifically related to a kind of special fixture processing connection steel band assembly.
Background technology
Connect steel band assembly and comprise steel band, rivet, packing ring and multiple gate block.Steel band and multiple gate block, by together with rivet, ensure that gate block can freely rotate; Steel band is processed into by sheet metal, and there is multiple hole centre; Gate block is arc, opens V-type groove in centre, and centre has a hole to communicate with V-type groove; Left-hand thread connection seat is identical with the structure of right-hand thread connection seat, and just screwed hole is left hand thread and right-handed thread.Left-hand thread connection seat and right-hand thread connection seat and arc-shaped steel belt weld together, inner arc radius, the inner mold of left-hand thread connection seat, right-hand thread connection seat and multiple gate block are identical with width dimensions, ensure the center of the groove of left-hand thread connection seat, right-hand thread connection seat and multiple gate block on the same line after connecting steel band component assembling.
Connect the steel band assembly processing method adopting routine usually more, first process steel band, left-hand thread connection seat, right-hand thread connection seat and each part of multiple gate blocks, be then assembled together on request.When processing steel band, first processing steel band and ensureing long and wide, then with the limit location drilling of steel band, because steel band material is Q235, length 1052mm, wide 20mm, thickness 1mm.The common processing method of steel band, for using plate shearing machine for blanking, is processed both sides with planer, is then being holed with drilling machine.Because steel band length is long, thickness is less, and when processing two long limits with planer, distortion appears in two long limits, do not ensure the linearity of steel band, then use the long limit location drilling of steel band, locate inaccurate, do not ensure the symmetry requirement in each hole, adopt planer processing, inefficiency simultaneously.
In order to solve the processing of steel band, processing method can be changed.
When processing steel band, with plate shearing machine for blanking, width one side stays allowance 0.5mm, and makespan ensures product length.Bore each hole with location, one side Special drill jig of steel band at steel band center line, ensure the center of circle linearity in each hole.With the groove of the hole of steel band and left-hand thread connection seat, right-hand thread connection seat location, welding steel band and left-hand thread connection seat, welding steel band and right-hand thread connection seat, ensure solder technology requirement, ensures left-hand thread connection seat, the groove of right-hand thread connection seat and the symmetry in steel band hole.After riveted joint gate block on lathe the both sides of turning steel band, ensure width.But not revolving body owing to connecting steel band assembly, can not lathe process be used.
Utility model content
The utility model in order to the machining accuracy solving existing connection steel band assembly low, and the problem that production efficiency is low, and then propose a kind ofly to process the special fixture connecting steel band assembly.
The utility model is solve the problems of the technologies described above the technical scheme taked to be: the utility model comprises clamp body, clamp body is hollow shaft, the axis of clamp body is coaxial with lathe spindle, the left side of clamp body is provided with taper locating hole, taper locating hole coordinates with the main shaft orientation face on lathe, the left side of clamp body is laid with four screwed holes, screwed hole by bolt and lathe spindle affixed, the left side of clamp body is provided with dowel hole, detent fit on dowel hole and main shaft, the external peripheral surface of clamp body is provided with boss, the height of boss is greater than the left-hand thread connection seat on connection steel band to be processed, the degree of depth of the inside groove of right-hand thread connection seat and multiple gate block, boss is installed on left-hand thread connection seat, in the inside groove of right-hand thread connection seat and multiple gate block.
The beneficial effect that the utility model compared with prior art comprises is: the utility model can complete the turnery processing of width of steel band on engine lathe, this fixture is adopted to carry out the processing of steel band accessory turning, not only overcome the technical barrier that long thin perforated plate class part is processed on lathe, also meet the requirement that parts batch is produced simultaneously, this clamp structure is simple, clamping is simple, feed is fast, process-cycle is short, connection steel band assembly is made to become revolving body, turning steel band both sides on lathe, while making the linearity of steel band reach 0.05mm, ensure that the symmetry in hole on steel band can reach 0.1mm, adopt lathe process, production efficiency improves 80%, also can be generalized in the middle of field of machining long thin perforated plate class accessory turning technology simultaneously.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram connecting steel band assembly; Fig. 2 is the structural representation of clamp body 1 in the utility model; Fig. 3 is the left view of Fig. 2; Fig. 4 is the structural representation of studs 2 in the utility model; Fig. 5 is the left view of Fig. 4.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 to Fig. 3 illustrates present embodiment, described in present embodiment, a kind of special fixture connecting steel band assembly of processing comprises clamp body 1, clamp body 1 is hollow shaft, the axis of clamp body 1 is coaxial with lathe spindle, the left side of clamp body 1 is provided with taper locating hole 1-1, taper locating hole 1-1 coordinates with the main shaft orientation face on lathe, the left side of clamp body 1 is laid with four screwed hole 1-2, screwed hole 1-2 by bolt and lathe spindle affixed, the left side of clamp body 1 is provided with dowel hole 1-4, detent fit on dowel hole 1-4 and main shaft, the external peripheral surface of clamp body 1 is provided with boss 1-3, the height of boss 1-3 is greater than the left-hand thread connection seat 4 on connection steel band 3 to be processed, the degree of depth of the inside groove of right-hand thread connection seat 5 and multiple gate block 6, boss 1-3 is installed on left-hand thread connection seat 4, in the inside groove of right-hand thread connection seat 5 and multiple gate block 6.
