Do you know how to clamp a boring and milling machine?

(1) Drilling and arranging holes, drilling and arranging holes on a larger workpiece can directly clamp the workpiece on the workbench, and clamp the workpiece with pressure plate bolts. The clamping position should be reasonably symmetrical. In order to prevent drilling damage to the workbench, the drilling position can be set in the T-groove of the workbench. If the diameter of the hole is larger than the width of the straight groove, a parallel pad should be inserted between the workpiece and the table. Note that after the machine mattress is put into the cushion block, the clamping position of the pressure plate should fall on the cushion block. Generally, the center of the hole is found by pre-marking, proofing and punching, and the reference circle of the trial drilling cone pit can be planned by marking the more accurate hole. (2) Drill radial holes on the shaft, and drill radial holes on the cylindrical surface of shaft parts, so that the workpiece can be stuck in the V-shaped groove of the V-shaped block. For long workpieces, V-shaped blocks with the same height should be used, and pressure plates and bolts should be installed reasonably. The clamping point of the pressure plate should be located in the V-shaped groove. When clamping the workpiece, it should be noted that the V-shaped groove surfaces of the two V-shaped blocks should be in contact with the circumferential surface of the workpiece, and the clamping operation should gradually clamp the two pressure plates in turn. The axial position of the hole is determined by scribing, and the radial position of the hole is generally aligned by drawing a reticle on the end face. When drilling, the center drill should be used to align the sample drilling cone hole, and then the twist drill should be used to drill the hole. (3) Drilling equal-diameter holes, that is, drilling equal-diameter holes on the workpiece, so that the workpiece of the machine tool can be clamped on the indexing head or the rotating workbench, and clamping the rectangular workpiece with a four-jaw single-acting chuck. Clamp the four-jaw Dandong chuck on the turntable, and then clamp the turntable on the milling machine for processing. After machining a hole, you can turn an equal angle and drill the next hole. The diameter of the hole distribution circle can be determined by pre-marking. (4) Drilling a through hole, that is, drilling a through hole on a smaller rectangular workpiece. The workpiece can be clamped by a machine tool with flat pliers, and a parallel pad can be inserted between the workpiece and the positioning surface of the machine tool guide rail with flat pliers. Note that parallel pads should be equal in height on both sides of the drilling position. The position and size of holes and datum planes are determined by pre-marking and inspection.
