The specific embodiment
To combine below accompanying drawing to the utility model make detailed introduction: Fig. 1,2, shown in 3; The utility model mainly comprises: a main shaft extension bar 12; Connect body 22 before meeting body 8 and one after one, said main shaft extension bar 12 connects on the rear end screw thread of body 8 after being connected along the axle center successively through locking back-up ring 14, locking nut 15; Connect after said body 8 front ends with before connect body 22 rear ends all offer one with the wide groove of intermediate slider 17, and become to move with the touch with intermediate slider 17 active face through this groove; Connecing body 22 before said is socketed in the joint overcoat 5; Said joint overcoat 5 is through connecing after being threaded on the body 8 front end screw threads, and adopts dog screw 16 location; The afterbody that connects body before said is provided with a keyway, and said keyway locks with keyway on the cutter extension bar 1 through flat key 23 mutually.
Said main shaft extension bar 12 with after connect body 8 between centers and set gradually and be useful on positioning screw 9, lock-screw 10 and the positioning steel ball 11 of setting up the position.
Connect body 8 and intermediate slider 17 between centers after said, intermediate slider 17 with before connect body 22 between centers, the preceding body 22 that connects is respectively arranged with antifriction steel ball 7,18,19 with joint overcoat 5 between centers.
The junction that connects body 22 and cutter extension bar 1 before said is with a quick-change connected set 21, is provided with a spacing steel ball 3 in the said quick-change connected set 21.
The practical implementation process:
One, sees Fig. 2,, connect the positioning screw 9 in body 8 tails after the adjusting, then with lock-screw 10 lockings according to the cutter extension bar 1 relative position needs of system; With placing positioning steel ball 11 behind the lock-screw 10 to push up at the bottom of main shaft extension bar 12 holes; With after connect circle in flat key 13 and main shaft extension bar 12 front ends on the body 8 keyway be connected; With place locking nut 15 on the main shaft extension bar 12 front end cylindricals, locking back-up ring (two pairs are cutd open semicircle) 14 with after connect the thread connection of body 8 and it is locked.So far on the main shaft extension bar 12 that is connected in drive disk assembly that the utility model is firm, with the multiaxis that adapts to system of processing, two-sided synchronous processing request.
Two, cutter extension bar 1 realizes that through the following step quick change connects with the utility model:
A, rapid coupling: the endoporus and the keyway that connect body 22 before cutter extension bar 1 and flat key 23 fixed thereon aimed at respectively; When before cutter extension bar 1 inserts, connecing body 22 endoporus and keyway, will connect lasso 21 soon toward pusher; Connect spring 20 soon owing to the barrier effect that connects the spacing back-up ring 4 on the body 22 before being fixed on compresses the power of holding this moment; Before the spacing steel ball 3 that connects in the body 22 steel ball locating holes can be movable in the neutral gear that connects lasso 21 soon along locating hole, cutter extension bar 1 connects body 22 endoporus before inserting smoothly; Unclamp then and connect lasso 21 soon, connect spring 20 soon and have an effect and before connecing lasso 21 soon, push away, the neutral gear inclined-plane that connects lasso 21 soon blocks spacing steel ball 3 V-shaped groove of cutter extension bar 1 along locating hole; Connect lasso 21 soon owing to connect stopping and the thrust that connects spring 20 soon of body 22 upper limit back-up rings 2 before being fixed on, be fixed on the position that connects locking, cutter extension bar 1 connects completion with the utility model.
B, fast quick-detach: will connect lasso 21 soon toward pusher; Connect spring 20 soon owing to the barrier effect that connects the spacing back-up ring 4 on the body 22 before being fixed on compresses the power of holding this moment; Before the spacing steel ball 3 that connects in the body 22 steel ball locating holes can be movable and break away from the V-shaped groove of cutter extension bar 1 in the neutral gear that connects lasso 21 soon along locating hole, connect body 22 endoporus before cutter extension bar 1 is extracted smoothly; Unclamp then and connect lasso 21 soon, reset owing to connecing stopping with the thrust that connects spring 20 soon of body 22 upper limit back-up rings 2 before being fixed on, cutter extension bar 1 is accomplished with the utility model dismounting.
Remarks: because cutter extension bar 1 is to adopt the V-shaped groove location with spacing steel ball 3, so can arrange a plurality of spacing steel balls 3, to bear biaxial load as far as possible according to the actual arrangement space that preceding connects body 22 steel ball locating holes.
Three, the internal structure of the utility model, error compensation and noise abatement measure:
A, internal structure: after connect body 8 front ends have one with the wide groove of intermediate slider 17, this groove becomes to move with the touch with intermediate slider 17 active face; Intermediate slider 17 biends have the cannelure of placing antifriction steel ball 7,18 (to be simplified
Technology guarantees machining accuracy), and installed spacer pin 6 and rolled within the specific limits along the cross direction respectively at intermediate slider 17 biends with restriction antifriction steel ball 7,18; Antifriction steel ball 7 in the intermediate slider 17 with after connect body 8 front end bottom lands and contact, and can roll along intermediate slider 17 glide directions; Before connect body 22 rear ends also have one with the wide groove of intermediate slider 17, this groove with after connect body 8 grooves and become the arrangement of cross direction, and become to move with the touch with intermediate slider 17 active face; Antifriction steel ball 18 in the intermediate slider 17 with before connect body 22 rear end slots at the bottom of contact, and can roll along intermediate slider 17 glide directions; Be placed with antifriction steel ball 19 preceding connecing 5 in body 22 shaft shoulders and joint overcoat, this steel ball can be within the specific limits along arbitrary directional rolling; Joint overcoat 5 through thread connection after connect on the body 8 front end screw threads, and adopt the dog screw location.
B, error compensation: lathe is when processing work; The main shaft extension bar 12 of power part initiatively must be by centre of gyration revolution separately with the passive even part cutter extension bar 1 of technological equipment; Owing to certainly exist the systematic error of sagittal plane between power part and the technological equipment; If it is not effectively compensated and direct coupled words, will inevitably bring bigger influence to the machining accuracy of member, the service life of technological equipment and the vibration of equipment.The utility model is through intermediate slider 17, along after connect body 8 and before connect body 22 groove do to slide relatively to (be among Fig. 2 Y, Z axial), synthesizing with O is the center of circle, is the plane with Y, Z axle, the circumferential nothing of 360 degree is interfered compensation.X axis system gap in the utility model; Be to connect body 8 after joint overcoat 5 is adjusted and antifriction steel ball 7, intermediate slider 17, antifriction steel ball 18, the preceding gap that connects between body 22, the antifriction steel ball 19 reach the regulation requirement, and positioned by dog screw 16 through regulating.Size that the axial float error that the utility model and cutter extension bar are 1 is (during assembling) through adjustment cutter extension bar 1V shape groove, quick-change connected set 21 with carry out that error range controls cooperating of 3 of spacing steel balls.
C, noise abatement measure: be prone to produce the intrinsic defective of noise when the crosshead shoe shaft coupling runs up for effectively reducing; The utility model after connect body 8 and intermediate slider 17 between centers; Intermediate slider 17 with before connect body 22 between centers, the preceding body 22 that connects adds antifriction steel ball 7,18,19 respectively with joint overcoat 5 between centers, and is aided with lubricating grease; Make former sliding friction between axial convert rolling friction into, effectively reduce the noise that utility model produces in the processing running course of work.
