Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, the utility model describes a kind of adjustable rhombus pin retention mechanisms for Workpiece fixing, comprise rhombus key seat 1, rhombus pin 2 and adjustment block 3, and rhombus key seat 1 is positioned at the below of rhombus pin 2, and adjustment block 3 is positioned at the side of rhombus key seat 1.
Wherein, adjustment block 3 is for having the L-type structure on two limits and being fixed by adjustment block construction bolt 31 and cylindrical pin with internal thread 5;
Preferably, the quantity of adjustment block construction bolt 31 is 3, and the quantity of cylindrical pin with internal thread 5 is 2.
Meanwhile, be provided with between two limits of adjustment block 3 and adjacent rhombus key seat 1 sidewall and adjust pad 4, and this adjustment pad 4 is fixed by clamping screw 7;
Preferably, the quantity adjusting pad 4 and clamping screw 7 is 2
As shown in Figure 3, Figure 4, above-mentioned rhombus key seat 1 is fixed by rhombus key seat construction bolt 11, and its inside is also provided with thin bushing 8, and above-mentioned rhombus pin 2 is inserted rhombus key seat 1 by this thin bushing 8 and is fixed by rhombus pin construction bolt 6.
Preferably, rhombus pin construction bolt 6 is positioned at the bottom of rhombus pin 2 and quantity is 4, and above-mentioned adjustment block construction bolt 31, rhombus pin construction bolt 6 and clamping screw 7 are M5 type bolt, M wherein represents metric thread, and M5 is a kind of expression way of metric thread, namely the nominal diameter of M5 bolt is 5mm, and outside dimension is close to 3/16 inch (about 4.76mm) of English system, the i.e. Bolt sizes of per inch 24 tooth.
