Description
Technical field
The utility model belongs to manufacturing technology equipment, particularly a kind of eccentric shaft calibration vehicle clamper.
Background technology
Two off-axis Lou parts are one of parts commonly used in many plant equipment, and the eccentric processing error that its top two eccentric segments allow is less, and difficulty of processing is big; The general in the past processing unit (plant) extremely easily that adopts, working (machining) efficiency is low, damages the lathe tool tool easily; The dimensioned precision is low; Morpheme worker's difference is difficult to guarantee, causes product percent of pass low, waste of manpower and material resources.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, and a kind of simple in structure, easy to operate, highly versatile, time saving and energy saving eccentric shaft calibration vehicle clamper are provided.
The technical scheme that the utility model technical solution problem adopts is: eccentric shaft calibration vehicle clamper comprises base plate, plain washer, base of the carrier head, base plate lining, ball bearing, bearing (ball) cover; Be characterized in establishing stepped bore at the base plate center; In stepped bore, set a sleeve; Adorn ball bearing between abutment sleeve and the base plate, ball bearing is pushed down with bearing (ball) cover and is with soket head cap screw and spring washer that bearing (ball) cover, abutment sleeve and base of the carrier head is together fastening, and symmetry is established two base plate bush hole on the base plate in the ball bearing outside; Adorn the base plate lining in a base plate bush hole therein; The base of the carrier head bush hole is established in corresponding base plate bush hole position on base of the carrier head, clamping headstock lining in the base of the carrier head bush hole, and dress cylinder connecting axle is connected the calibration alignment pin in base plate lining and base of the carrier head lining; Dress compression spring is also pushed down with the handwheel gland on the cylinder connecting axle; On the calibration alignment pin, adorn handwheel, shock mount chuck in the center internal taper hole of abutment sleeve and base of the carrier head correspondence, collet is threaded fixing with binding nut with base of the carrier head.
The beneficial effect of the utility model is: it is the eccentric shaft of 180 degree that eccentric shaft calibration vehicle clamper can be accomplished the identical and phase difference of eccentric throw through the single clamping, and the multiple turning processing of multi-eccentric section adopts collet to cooperate clamping to locate with the calibration alignment pin; Compare than conventional brace, reduce cutter and lose, easy to operate; Time saving and energy saving, use cost is low, and the mismachining tolerance of workpiece is effectively controlled; Guarantee product quality, enhance productivity.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is that eccentric shaft calibration vehicle clamper structure master looks cutaway view.
Fig. 2 is the right side view of Fig. 1.
Among the figure, the 1-base plate; The 2-screw; The 3-plain washer; The 4-abutment sleeve; The 5-spring washer; The 6-soket head cap screw; The 7-bearing (ball) cover; The 8-ball bearing; 9-base plate lining; The 10-base of the carrier head; 11-handwheel gland; The 12-handwheel; 13-cylinder connecting axle; 14-calibration alignment pin; 15-compresses spring; 16-base of the carrier head lining; The 17-binding nut; The 18-collet.
The specific embodiment
Embodiment; With reference to accompanying drawing 1,2; Eccentric shaft calibration vehicle clamper is to be provided with shoulder hole at the center of base plate 1, and abutment sleeve 4 is housed in shoulder hole, between abutment sleeve 4 and base plate 1, ball bearing 8 is housed; Ball bearing 8 usefulness bearing (ball) covers 7 are pushed down and be with soket head cap screw 6 and spring washer 5 that bearing (ball) cover 7 is fixing, and are simultaneously that the base of the carrier head 10 on abutment sleeve 4 right sides is fixing with it.Symmetry is established two base plate bush hole on the base plate 1 in the outside of ball bearing 8; Adorn base plate lining 9 in a base plate bush hole therein; Corresponding base plate bush hole is established the base of the carrier head bush hole on base of the carrier head 10, and clamping headstock lining 16 in the base of the carrier head bush hole is connected calibration alignment pin 14 with cylinder connecting axle 13 in base plate lining 9 and base of the carrier head lining 16; Dress handwheel 12 on the calibration alignment pin 14; Dress compression spring 15 is also pushed down with handwheel gland 11 on the cylinder connecting axle 13, shock mount chuck 18 in the internal taper hole, center of abutment sleeve 4 and base of the carrier head 10 correspondences, and collet 18 usefulness binding nuts 17 are threaded fixing with base of the carrier head 10.
The method for using of eccentric shaft calibration vehicle clamper is before clamping, unclamps binding nut 17, makes collet 18, is in relaxed state, places collet 18 and abutment sleeve 4 to carry out clamping and positioning to be processed positioning end.After clamping finished, base plate 1 places 300 chucks (or 400 chucks) of engine lathe to fix or be directly fixed on the lathe just can carry out eccentric side turning.After one section eccentric shaft part machines, with portable handwheel 12 calibration alignment pin 14 is inserted in another base plate lining 9 endoporus, carry out the corresponding turning of the eccentric shaft part of next section.
