Abstract
The invention discloses a scratch-free boring technique for a chain piece. According to the scratch-free boring technique for the chain piece, two boring tool bits which are fed synchronously are used for machining two shaft holes of the chain piece at the same time, the two boring tool bits are both provided with a main blade used for machining the corresponding shaft hole, and one of the boring tool bits is further provided with an auxiliary blade used for machining a dustproof hole. The scratch-free boring technique for the chain piece comprises the steps that 1, the chain piece is placed on a clamping device and is clamped and fixed; 2, the directions of the main blades of the two boring tool bits are adjusted to be identical; 3, the two boring tool bits are fed until the main blades stretch out of the shaft holes, fine boring of the shaft holes is completed, then primary tool retracting is conducted to enable the main blades to be still located outside the shaft holes and the auxiliary blade to retract out of the dustproof hole, the two boring tool bits stop rotating, and the main blades and the auxiliary blade do not make contact with the chain piece; 4, the directions of the main blades of the two boring tool bits are adjusted so that the main blades of the two boring tool bits can both face the left side or the right side, the chain piece is loosened by the clamping device, the chain piece is moved horizontally towards the main blades in the length direction of the chain piece so that the main blades can avoid the walls of the shaft holes, then the chain piece is clamped by the clamping device, and the two boring tool bits retract.
Description
Technical field
The present invention relates to a kind of chain sheet boring process.
Background technology
Known, crawler belt chain forms primarily of some chain links that head and the tail are hinged, the chain sheet that chain link is oppositely arranged primarily of two, be arranged on the axle between two chain sheet one end and be arranged on the axle sleeve composition between the two chain sheet other ends, chain sheet one end is formed with the first axis hole (aperture) passed for described axle, the other end is formed with the second axis hole (macropore) passed for described axle sleeve, chain sheet medial surface is also formed with the dust-proof hole coaxial with the first axis hole, dust-proof hole is for installing dust ring, usual first, the processing in the second axis hole and dust-proof hole synchronously completes on boring machine, the workbench of boring machine is arranged the clamping device being used for fixing chain sheet crude green body, be provided with for processing first, the two bore hole cutter heads in the second axis hole and dust-proof hole, two bore hole cutter heads all have the major cutting edge for processing axis hole, wherein a bore hole cutter head also has the auxiliary-blade for processing dust-proof hole, current first, second axis hole and dust-proof hole are employing two bore hole cutter head synchro-feed and the mode of synchronous withdrawing is processed, this mode is when withdrawing, the inwall of major cutting edge meeting scratch two axis hole, scratch is formed at inwall, affect the quality of chain sheet.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of without scratch chain sheet boring process.
Object of the present invention realizes by following technical solution:
A kind of without scratch chain sheet boring process, it is characterized in that: adopt two bore hole cutter heads of synchro-feed to process two axis holes of chain sheet simultaneously, two bore hole cutter heads all have the major cutting edge for processing axis hole, wherein a bore hole cutter head also has the auxiliary-blade for processing dust-proof hole, comprises the steps:
(1), by chain sheet be placed on clamping device, and be fixedly clamped;
(2), regulate the major cutting edge of two bore hole cutter heads towards, make the major cutting edge of two bore hole cutter heads towards identical;
(3), two bore hole cutter heads are fed to major cutting edge and stretch out outside axis hole, complete axis hole right boring, then carry out first withdrawing, make that major cutting edge is also in outside axis hole, auxiliary-blade exits dust-proof hole, two bore hole cutter heads stop operating, and at this moment major and minor blade does not all contact with chain sheet;
(4), regulate two bore hole cutter head major cutting edges towards, make the major cutting edge of two bore hole cutter heads all towards left or right direction, clamping device unclamps chain sheet, by chain sheet towards major cutting edge side along chain leaf length direction translation certain distance, major cutting edge is made to avoid axis hole hole wall, then clamping device clamp chain sheet, two bore hole cutter heads carry out withdrawing.
By chain sheet translation 1-3mm in described step (3), major cutting edge is made to avoid main aperture hole wall.
The present invention has following beneficial effect:
First first withdrawing is carried out before complete withdrawing, make that major cutting edge is also in outside axis hole, auxiliary-blade exits dust-proof hole, unclamp chain sheet and make major cutting edge avoid axis hole hole wall the translation of chain sheet, then clamp chain sheet carries out withdrawing, major cutting edge so can be made to avoid axis hole hole wall, thus effectively avoid major cutting edge scratch shaft hole inner wall.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention, completes axis hole right boring.
Fig. 2 is structural representation of the present invention, first withdrawing.
Fig. 3 is structural representation of the present invention, and chain sheet, towards the translation of major cutting edge side, makes major cutting edge avoid axis hole hole wall.
Detailed description of the invention
Shown in Fig. 3, a kind of without scratch chain sheet boring process, adopt first, second bore hole cutter head 2,3 of synchro-feed to process two axis holes 11,12 of chain sheet 1 simultaneously, first, second bore hole cutter head 2,3 all has the major cutting edge 21,31 for processing axis hole 11,12, first bore hole cutter head 2 also has the auxiliary-blade 22 for processing dust-proof hole 13, comprises the steps:
(1), by chain sheet 1 be placed in clamping device (not shown), and be fixedly clamped, clamping device is known features, here no longer describes in detail;
(2), regulate the major cutting edge 21,31 of first, second bore hole cutter head 2,3 towards, make the major cutting edge 21,31 of first, second bore hole cutter head 2,3 towards identical;
(3), first, second bore hole cutter head 2,3 is fed to major cutting edge 21,31 and stretches out outside axis hole 11,12, complete axis hole right boring, then first withdrawing is carried out, make that major cutting edge 21,31 is also in outside axis hole 11,12, auxiliary-blade 22 exits dust-proof hole 13, first, second bore hole cutter head 2,3 stops operating, and at this moment major and minor blade 21,31,22 does not all contact with chain sheet 1;
(4), regulate the major cutting edge 21,31 of first, second bore hole cutter head 2,3 towards, make the major cutting edge 21,31 of first, second bore hole cutter head 2,3 all towards right direction, clamping device unclamps chain sheet 1, by chain sheet 1 towards left direction translation 1-3mm, major cutting edge 21,31 is made to avoid axis hole 11,12 hole wall, then clamping device clamp chain sheet 1, first, second bore hole cutter head 2,3 carries out withdrawing.
