Abstract
The utility model discloses a fixing device used in the field of mechanical machining and design, and particularly relates to a fixing device for the hole turning of a connection rod. The fixing device comprises a packing, sliders, pull rods, a fixing disc, a hole turning flat plate and a positioning plate; two sliders and two pull rods are positioned at the upper end of the packing; the upper ends of the pull rods are connected with a horizontally placed press plate; the lower ends of the pull rods are connected with a cylinder by the sliders; the hole turning flat plate and the positioning plate are arranged at the upper part of the fixing disc in sequence. The fixing device for the hole turning of the connection rod has the advantages that the positioning plate is the V-shaped structure, has good universality, is suitable for workpieces of different sizes and standards and realizes the fast and reliable positioning and clamping of connection rod-type workpieces. The fixing device is simple in structure and high in reliability, the assisting time for the hole turning of the workpieces is shortened and the production efficiency and the machining precision of the workpiece machining are improved.
Description
Technical field
The utility model relates to a kind of machining design field fixture, specifically, relates to a kind of fixture that is applicable to connecting rod car hole.
Background technology
Utilize engine lathe to carry out car hole to connection rod type workpiece and add man-hour, not high to the appearance and size required precision of workpiece, and higher for position and the dimension precision requirement of macropore on connecting rod and aperture.
Traditional method is first on connecting rod workpiece, to draw the position in car hole, then according to drawn hole line and four paws claw clamping, centering, finally again according to endoporus centering grinding hole, this kind of mode is comparatively applicable for the not high workpiece hole-turning of requirement on machining accuracy, but for the higher workpiece of eccentric throw precision prescribed, need to there is strict requirement to the pitch of holes in car hole, for guaranteeing physical dimension and the geometric accuracy of workpiece, need to there is special clamping and fixing device, in particularly producing in enormous quantities, the production efficiency that traditional processing technology has a strong impact on and machining accuracy.
Utility model content
The purpose of this utility model is the shortcoming in the machining process of car hole for existing connection rod type workpiece, provide a kind of reliably, connecting rod car hole fixture that precision is high.
The technical solution of the utility model is: a kind of connecting rod car hole fixture, be fixed on lathe spindle, it is characterized in that: this fixture comprises packing, slide block, pull bar, fixed disk, car hole flat board and location-plate, described slide block and pull bar are positioned at packing upper end, respectively there are two, pull bar upper end is connected with a pressing plate of laterally placing, and lower end is connected with cylinder by slide block; The top of fixed disk is provided with car hole flat board and location-plate successively.
Preferably, described location-plate is V-structure, and location-plate longitudinal axis place is provided with clamping screw.
Preferably, described pressing plate and pull bar upper end are fixed by fillister head screw.
Preferably, described pull bar and fixed disk contact position are provided with wear-resisting copper sheathing, and copper sheathing is positioned at the outer end of pull bar.
Preferably, between described packing and fixed disk, be provided with mounting bracket, fixed disk and mounting bracket are bolted.
The utility model beneficial effect is compared with prior art:
(1) pull bar lower end is connected with cylinder by slide block, and the required drive that is fixedly clamped obtains from being installed on lathe upper cylinder, saves labour;
(2) location-plate is V-structure, location-plate longitudinal axis place is provided with clamping screw, connection rod type workpiece can easily fix to clamp the inside in V-structure, and V-structure has versatility well, be applicable to the workpiece of different size and specification, realize quick, the location clamping reliably of connection rod type workpiece;
(3) fixture of the present utility model, is fixed on lathe spindle, simple in structure, reliability is high, not only shortens the non-cutting time of workpiece hole-turning processing, and can improve production efficiency and the machining accuracy of workpiece processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-packing, 2-slide block, 3-pull bar, 4-fixed disk, 5-car hole is dull and stereotyped, 6-location-plate, 7-pressing plate, 8-clamping screw, 9-copper sheathing
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described:
Referring to Fig. 1, a kind of connecting rod car hole fixture, be fixed on lathe spindle, this fixture comprises packing 1, slide block 2, pull bar 3, fixed disk 4, car hole dull and stereotyped 5 and location-plate 6, slide block 2 and pull bar 3 are positioned at packing 1 upper end, respectively have two, pull bar 3 upper ends are connected with a pressing plate 7 of laterally placing, and lower end is connected with cylinder by slide block 2; The top of fixed disk 4 is provided with car hole dull and stereotyped 5 and location-plate 6 successively.
