Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1 to Fig. 3, the utility model comprises base plate 1, base plate 1 is provided with the fixed mechanism of multiple sets of teeth wheel pump pump housing workpiece 4 side by side, often organize fixed mechanism and comprise the multiple fixing station arranged continuously, therefore on same base plate 1, be provided with the fixing station of multiple gear pump body workpiece 4, achieve simultaneously to the technique effect that multiple workpiece loads.
Fixing station comprises and is fixed on the first cushion block 7 and the second cushion block 12 on base plate 1, that be oppositely arranged, two cushion blocks are used for the workpiece of this fixing station to pave certain altitude, and in the present embodiment, the first cushion block 7 and the second cushion block 12 all adopt sunk screw 6 to be fixedly connected with base plate 1.On base plate 1, the inner side of the first cushion block 7 offers the first pin-and-hole 8, and on base plate 1, the inner side of the second cushion block 12 offers in the second pin-and-hole 11, first pin-and-hole 8 and the second pin-and-hole 11 and be all inserted with pin, and two pins diagonally distribute.After gear pump body workpiece 4 is loaded on fixing station, the first pin-and-hole 8 and the second pin-and-hole 11 insert the connecting hole that a group of workpiece is positioned at diagonal position respectively, realize location, the precision of lifting workpieces processing.
