Abstract
The utility model discloses a cylinder sleeve vertical hinge self-centering fixture. The fixture comprises a hydraulic oil cylinder (1), a rack (4), clamping jaws (5), a base (7), a gear (8) and a fixing seat (9); the hydraulic oil cylinder (1) and the base (7) are mounted on a machine table; a piston rod (2) of the hydraulic oil cylinder (1) is connected with the rack (4) which is meshed with the gear (8); an inner circle assembly surface of the gear (8) matches with the fixing seat (9); the gear (8) is provided with three screw helicoids in uniform distribution along the inner circle peripheral direction; three clamping jaw holes in uniform distribution are reserved on the fixing seat (9) along the peripheral direction; the clamping jaws (5) are mounted in the clamping jaw holes; and big ends of the clamping jaws (5) are abutted against the crew helicoids of the gear (8) under the action of a spring (6). The cylinder sleeve vertical hinge self-centering fixture is simple in structure, convenient to operate and applicable to machining of cylinder sleeves of different kinds; centering is performed automatically according to outer circle shapes of cylinder sleeves; precise positioning of the cylinder sleeves is achieved; and machined cylinder sleeves have small difference in wall thickness.
Description
Technical field
The utility model relates to anchor clamps, is specifically related to the upright hinge of a kind of cylinder jacket self-centering fixture.
Background technology
The upright hinge of cylinder jacket manufacturing procedure adopts the centring ring location at present, and the shortcoming of this location is: 1, the location is inaccurate, and it is poor that interior circle processing produces relatively thick; 2, will be according to different cultivars cylinder sleeve excircle dimension centring ring customized.
Summary of the invention
The purpose of this utility model is: the upright hinge of a kind of cylinder jacket self-centering fixture is provided, can realizes the accurate location of cylinder jacket according to cylinder jacket cylindrical shape automatic capturing center.
Technical solution of the present utility model is: these anchor clamps comprise hydraulic jack, tooth bar, jaw, base, gear and holder, at platen hydraulic jack and base are installed, the piston rod of hydraulic jack connects tooth bar, the tooth bar meshing gear, the interior round fitting surface of gear cooperates holder, gear is opened three equally distributed Archimedes' helicoids along interior round Zhou Fangxiang, three equally distributed jaw holes along the circumferential direction left by holder, jaw is installed in the jaw hole, and the stub end of jaw is withstanding on the Archimedes' helicoid of gear under the effect of spring.
During work, cylinder jacket is installed in the holder through pressing down gear ring, the primer fluid compressing cylinder, piston rod drives the tooth bar moving linearly, the rack drives gear is made circular motion, promote three jaws when the Archimedes' helicoid of gear inside rotates and radially move to the center of circle, finally clamp cylinder jacket and make the cylinder jacket self-centering.
The utility model is simple in structure, and is easy to operate, according to cylinder jacket cylindrical shape automatic capturing center, realizes the accurate location of cylinder jacket, and the cylinder jacket wall thickness difference that processes is very little, is applicable to several different cultivars cylinder jacket processing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 hydraulic jack, 2 piston rods, 3 cylinder jacket, 4 tooth bars, 5 jaws, 6 springs, 7 bases, 8 gears, 9 holders, 10 press down gear ring.
The specific embodiment
As shown in Figure 1, these anchor clamps comprise hydraulic jack 1, tooth bar 4, jaw 5, base 7, gear 8 and holder 9, at platen hydraulic jack 1 and base 7 are installed, the piston rod 2 of hydraulic jack 1 connects tooth bar 4, tooth bar 4 meshing gears 8, the interior round fitting surface of gear 8 cooperates holder 9, gear 8 is opened three equally distributed Archimedes' helicoids along interior round Zhou Fangxiang, three equally distributed jaw holes along the circumferential direction left by holder 9, jaw 5 is installed in the jaw hole, and the stub end of jaw 5 is withstanding on the Archimedes' helicoid of gear 8 under the effect of spring 6.
During work, cylinder jacket 3 is installed in the holder 9 through pressing down gear ring 10, primer fluid compressing cylinder 1, piston rod 2 drives tooth bar 4 moving linearlies, tooth bar 4 driven gears 8 are made circular motion, promote three jaws 5 when the Archimedes' helicoid of gear 8 inside rotates and radially move to the center of circle, finally clamp cylinder jacket 3 and make the cylinder jacket self-centering.
