Embodiment 1
[0038] See this example figure 1 , figure 2 and image 3 , which includes a suction table and an auxiliary device, characterized in that: the suction table is a suction table 18 comprising an iron base plate 19 and a vacuum chuck 36, and the auxiliary device is a vacuum pump device 1; a suction table is installed on the suction table 18 Box 20, the suction table box 20 is fixed on the iron base plate 19, and the outer mounting plate 32 and two handles 14 at both ends are also installed on the iron base plate 19, and the leak-proof ball valve 29 is fastened on the outer mounting plate 32, and the suction table box 20 The top plate 38 of the top plate is used as a working table for sucking grinding parts. The horizontal clamping plate 21 and two vertical clamping plates 22 are fastened by countersunk screws on the left side of the top plate 38. The vertical clamping plate 22 and the horizontal clamping plate 21 are vertically supported on the horizontal At both ends of the cl...
Embodiment 2
[0043] The difference between this embodiment and the suction table implementation one is that three impact plate vacuum chucks 50 are installed on the suction table box 20, three suction cup through holes 49 are arranged on the top plate 38 of the suction table box 20, and each impact plate uses a vacuum The upper end of sucker 50 is inserted into corresponding sucker through hole 49, (one sucker through hole 49 is inserted), and four-way joint 47 is also installed in the sucker box 20, and wherein three joints are connected by a short sucker connecting pipe respectively. 48 is connected with the impact plate with a vacuum suction cup 50, and the other joint is connected with the tee joint 27. Each impact plate is sucked with a vacuum suction cup 50 for one impact workpiece, and the impact plate draw-in groove 51 places three impact workpieces, see Figure 6 , the others are the same as the first embodiment of the suction table.

Embodiment 2
[0050] This embodiment is realized by using the second embodiment of the suction table, and the impact workpiece is placed in the groove 51 of the impact plate, and the others are the same as the first embodiment of the adsorption method.
[0051] illustrate
[0052] The top plate 38 of the above two embodiments requires sufficient hardness to counteract the repeated wear of a large number of samples, so its material is selected as No. 45 steel.
[0053] The heat treatment process is determined as quenching heat treatment, and the scheme is as follows:
[0054] ⑴ Quenching treatment: put into the furnace at 860°C, heat for 1 hour, and quench in water.
[0055] ⑵ Tempering treatment: Temper in an oven at 200°C for 2 hours.
[0056] ⑶ Hardness value: 52 HRC.
[0057] vacuum pump 9
[0058] Since a large amount of grinding wheel chips, waste chips and cooling grinding fluid are produced during the grinding process, some of them inevitably enter the vacuum pipeline. Therefore,...
