Abstract
The invention discloses a molding sand clearing device for a pneumatic cylinder cover inner cavity in the field of cylinder cover machining and manufacturing. The molding sand clearing device comprises a rack, a support mechanism, an air pump and a silencing mechanism. The air pump is located at the top end of the rack. The support mechanism comprises a support plate and an installation plate. The support plate is located on the lower portion of the rack. The installation plate is located above a vibrating plate. A high pressure blower gun which is connected with the air pump is installed on the installation plate. A vibrating spring is arranged on the support plate. The vibrating plate is arranged at the upper end of the vibrating spring and provided with a vibrating motor and a limiting block. The vibrating plate and the support plate are both provided with sand dropping holes. The silencing mechanism is fixed to the side wall of the rack. A sand collecting box is arranged below the support plate. According to the scheme, molding sand remained in a cylinder cover is cleared up more thoroughly, and the sand dropping ratio is higher. The cylinder cove is buffered through the vibrating spring, so that the defects such as deformation or cracks caused by repeated blows of compressed air to the cylinder cover are effectively avoided, and the defective percentage caused by inner machining is lowered. Noise generated inside is absorbed and weakened through a sponge silencing layer, so that noise pollution is reduced.
Description
Technical field
The present invention relates to cylinder cap processing and manufacturing field, be specifically related to a kind of pneumatic cylinder cap inner chamber molding sand scavenge unit.
Background technology
Cylinder head is the fixture of diesel engine and the part of combustion chamber, and cylinder head is installed with fuel injector, rocker shaft bed indicator valve and inlet and outlet valve etc., there are entering and exhaust channel and cooling water cavity in cylinder head inside, and its complex structure, duct are more, wall unevenness.Cylinder cap is generally sand casting forming, and in actual production process, cylinder cap shaping rear needs removes the molding sand remaining in cylinder cap inner chamber.The sand removal equipment of prior art is primarily of parts compositions such as bed piece, vibrations striking mechanism, workbench, stage support slide rail, operation cabinets.Its operation principle removing molding sand is: fixed on the table by cylinder cap (workpiece), utilize vibrations striking mechanism by compressed air high speed vibration, cylinder cap (workpiece) is hit with certain hitting power, make that the molding sand inside cylinder cap (workpiece) inner chamber is shaken and fragmentation comes off, thus workpiece is cleaned out.
There is following shortcoming in the removing molding sand equipment of prior art: (1) is depended merely on vibrations striking mechanism and hit workpiece, and be difficult to effective knockout, knockout rate is low.(2) because workbench is fixed on bearing rails, absorb impulsive force without buffer structure when hitting operation, so that easily there is crackle when overwhelming in workpiece, causing product fraction defective high on the one hand, cause noise pollution on the other hand.
Summary of the invention
The invention is intended to provide a kind of pneumatic cylinder cap inner chamber molding sand scavenge unit, to improve knockout rate, avoid removing molding sand and damage is caused to cylinder cap.
For achieving the above object, basic technology scheme of the present invention is as follows: pneumatic cylinder cap inner chamber molding sand scavenge unit, comprise frame, supporting mechanism, air pump and silencer mechanism, described supporting mechanism comprises gripper shoe, installing plate, and described gripper shoe is laterally arranged on the bottom of frame.The upper end of gripper shoe is fixed with multiple vibrating spring, and the upper end of vibrating spring is fixed with oscillating plate.Oscillating plate outside vibrating spring is fixed with vibrating motor, and the upper end of oscillating plate is provided with the limited block for locating cylinder cap, and described oscillating plate and gripper shoe are equipped with some drop-holes.Described installing plate is fixed in the frame above oscillating plate, described installing plate is provided with vertical high pressure air pressure gun.Described frame is " door " shape frame structure, and described air pump is fixed on the top of frame, and described high pressure air pressure gun is connected with air pump.Described silencer mechanism is the sponge noise reduction layer be fixed on frame madial wall, and the below of described gripper shoe is provided with the silt box be slidably connected in frame, and the bottom of described silt box is provided with roller.
