The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
Wherein, Fig. 1 ~ 3rd, the structural representation of the connecting rod cap of prior art, for said structure, in the prior art, need to be the different machining tool of each different structural design.
Wherein, the utility model is for These characteristics, a kind of modular fixture using on horizontal Machining centers is provided, utilize the similar structure of bowl cover, all bowl cover mutual foundation fixtures, easy-to-dismount location-plate and compressing member are installed in base jig, are met the requirement of processing different type of machines bowl cover Bolt to position face.
As Fig. 4, 5, described in 6, it comprises: the clamp body 11 that comprises the base jig of connecting machine tool workbench and processed connecting rod cap, described clamp body is pressed on workbench by tommyhead bolt 19 and nut, location-plate 12 is installed above it, the upper plane of location-plate 12 is as the main locating surface of described connecting rod cap, limiting rod lid three degree of freedom, and be fixed on clamp body by housing screw 15 and alignment pin 18, wherein, the trailing flank of described location-plate 12 is provided with pin 16 and screw 17, be used for installing locating piece, prop up on the faying face of various type connecting rod caps, two frees degree of limiting rod lid, wherein, in the side of location-plate 12, side locating piece is installed, prop up on the side of various type connecting rod caps, the one degree of freedom of limiting rod lid, and be also provided with groove in described location-plate 12, removable long nut 13 and removable tommyhead bolt can move in the groove of location-plate 12, and described moving long nut 13 hypomeres are connected with removable tommyhead bolt, in moving long nut 13 epimeres, mounting stud is used for compressing connecting rod cap.
In addition, when in use, the location-plate 12 of described base jig all contacts with the end face of connecting rod cap, and the Bolt to position face of connecting rod cap is higher than described location-plate 12.
Wherein, as shown in Fig. 7,8,9,10, be also provided with connecting rod cap fixture, wherein, its schematic diagram for using, wherein, the title of all parts is followed successively by: side locating piece 1, pressing plate 2, packing ring 3, screw 4, rear locating piece 5, clamp nut 6,7,3 pressure heads 8 of stud.
That is to say, base jig is the shared parts of all connecting rod cap fixtures of processing, and clamp body 11 effects are connecting machine tool workbench and workpiece to be machined, and clamp body is pressed on workbench by tommyhead bolt 19 and nut, and location-plate and compressing member are installed above it.Location-plate 12 is to make with relatively hard materials, is used for bearing connecting rod lid, and upper plane is as the main locating surface of connecting rod cap, limiting rod lid three degree of freedom, and location-plate is fixed on clamp body by housing screw 15 and alignment pin 18.Location-plate 12 trailing flanks are provided with pin 16 and screw 17, are used for installing locating piece, prop up on the faying face of various type connecting rod caps two frees degree of limiting rod lid.In the side of location-plate 12, side locating piece is installed, props up on the side of various type connecting rod caps, the one degree of freedom of limiting rod lid.The six-freedom degree of connecting rod cap is limited completely, belongs to location completely.Removable long nut 13 and removable tommyhead bolt can move in the groove of location-plate 12, can meet different big or small connecting rod caps and clamp demand, moving long nut 13 hypomeres are connected with removable tommyhead bolt, and in moving long nut 13 epimeres, mounting stud is used for compressing connecting rod cap.
