A machining device for a pump cover of an end suction pump

Abstract

The application discloses a machining device for a pump cover of an end suction pump and relates to the technical field of end suction pump machining. The machining device comprises a workbench, a pressing mechanism and a drilling mechanism. A fixing seat is rotatably connected to the workbench. A positioning column is arranged on the fixing seat. The pressing mechanism is arranged on a support frame on the workbench. The drilling mechanism is arranged on a fixing frame on the workbench. The pump cover is pressed on the fixing seat by the pressing cylinder and the inserting rod on the pressing plate of the pressing mechanism. The extruding plate is driven to move downward by the drilling cylinder of the drilling mechanism, so that the extruding driving block moves towards the side plate of the pump cover. The side plate of the pump cover is reinforced by the reinforcing frame, so that the side plate of the pump cover is more stable during drilling. After the drilling is completed, the reinforcing frame is reset under the elastic force of the spring. The burrs at both ends of the hole on the side plate of the pump cover are polished by the polishing pieces on the inner wall of the reinforcing frame, so that the workers are prevented from being injured by the burrs when the pump cover is removed.

[0035] When drilling the pump cover 81, the center hole of the pump cover 81 to be drilled is sleeved on the positioning column 3 of the fixing base 2, and the pump cover 81 is rotated so that one of the side plates 811 is located directly above the through hole 11 of the workbench 1;

[0036] Then, the piston rod of the pressing cylinder 42 is controlled to extend, so that the inserting rod 432 on the pressing plate 43 moves downward, the inserting rod 432 on the pressing plate 43 is inserted into the mounting hole on the pump cover 81, and the pressing plate 43 presses the pump cover 81 against the fixing base 2;

[0037] Then, the drilling motor 66 is turned on, and the piston rod of the drilling cylinder 65 is controlled to extend, so that the extrusion plate 64 moves downward along the inner slide rail 71 of the fixing frame 7; when the extrusion inclined surface 641 on the side of the extrusion plate 64 contacts the driving inclined surface 631 on the driving block 63, the driving block 63 is extruded, the driving block 63 moves along the guide rod 62 towards the side plate 811 of the pump cover 81, the limiting groove 612 on the reinforcing frame 61 is sleeved on the side plate 811 of the pump cover 81, the drilling motor 66 continues to move downward, the drill bit 67 on the drilling motor 66 enters the reinforcing frame 61 through the drilling hole 613 on the reinforcing frame 61, the output shaft of the drilling motor 66 drives the drill bit 67 to rotate to drill the side plate 811 of the pump cover 81, and the generated debris can be discharged to the bottom of the workbench 1 through the discharge hole 614 on the reinforcing frame 61;

[0038] When the drilling of the side plate 811 of the pump cover 81 is completed, the piston rod of the drilling cylinder 65 is controlled to retract, so that the drill bit 67 of the drilling motor 66 moves upward; when the extrusion inclined surface 641 of the extrusion plate 64 contacts the driving inclined surface 631 of the driving block 63, the driving block 63 moves outward under the elastic force of the spring 622 on the guide rod 62, so as to drive the reinforcing frame 61 to move away from the side plate 811 of the pump cover 81; in the process of moving of the reinforcing frame 61, the burrs at both ends of the hole just drilled on the side plate 811 of the pump cover 81 are polished by the polishing piece 68 on the inner wall of the reinforcing frame 61;

[0039] When the reinforcing frame 61 is reset, the belt pulley one 45 on the output shaft of the driving motor 44 drives the belt pulley two 47 and the rotating disc 41 to rotate through the driving belt 46, so that the pump cover 81 on the fixing base 2 rotates; when the next side plate 811 of the pump cover 81 to be drilled is rotated to be directly below the drill bit 67, the rotation of the output shaft of the driving motor 44 is stopped, and then the side plate 811 is drilled.
