Abstract
The utility model discloses a sand box cover and body fastening structure, which comprises a box body and a box cover, wherein two vertical lugs are arranged on the surface of the box body below a convex plate at an upper port of the box body; a shaft pin penetrates through holes of the two vertical lugs; a large-diameter step body is arranged at one end of the shaft pin, and a hole matched with a cotter pin is formed in the other end of the shaft pin; a sphere at the lower end of a swing bolt is placed between the two vertical lugs; the left and right sides of the sphere are planes, and a hole matched with the shaft pin in a rotating manner is formed in the sphere; the swing bolt is matched with the convex plate at the box body port and a notch in a convex plate at a box cover port; and a nut is matched with a thread at the upper end of the swing bolt. Compared with the prior art, the sand box cover and body fastening structure has the remarkable advantages of high efficiency, small labor intensity and high safety and reliability.
Description
Technical field:
The utility model relates to a kind of casting sandbox, particularly the fastening structure of a kind of sandbox case lid and casing.
Background technology:
Foundry goods is blank commonly used in machinery, consumption is very large, and foundry goods is in casting cycle, because weight and its coefficient of expansion of molten iron are larger, can cause case lid by jack-up, the lighter's casting deformation and plate are useless, and the overflow of severe one molten iron is accidents caused, for avoiding moving the defects that causes on case lid, existing measure is to place weight on case lid, and weight leans on workman's experience, the shortcoming of this scheme to be, labour intensity is large and efficient is low.
Summary of the invention:
The purpose of this utility model is to provide a kind of labour intensity is low, efficient is high and safe and reliable a kind of sandbox case lid and the fastening structure of casing.
the technical scheme that realizes the utility model purpose is, the fastening structure of a kind of sandbox case lid and casing, comprise casing and case lid, it is characterized in that: be provided with two vertical otic placodes on the tank surface outside the casing upper port below flange, pivot pin is through in the hole of above-mentioned two vertical otic placodes, one end of this pivot pin is provided with large diameter step body, its other end is provided with the hole that matches with split pin, the lower end of waving bolt has a spheroid to be placed between two vertical otic placodes, the left side of this spheroid, right both sides are the plane, be provided with in this spheroid with above-mentioned pivot pin and turn the hole of joining, this breach that waves on the outer flange of bolt and described casing port evagination plate and case lid port matches, nut and the described screw thread that waves the bolt upper end match.
The utility model has the remarkable advantage that efficient is high, labour intensity is little and safe and reliable compared with the prior art.
Description of drawings:
Fig. 1 is perspective view of the present utility model; Fig. 2 is the structural representation that the utility model waves bolt tightening casing and case lid.
The specific embodiment:
in conjunction with above-mentioned accompanying drawing, the utility model is elaborated, bolt is waved in the utility model employing is connected case lid and casing, the otic placode 4 that fixedly parallels on the outer surface of casing 1 surrounding of sandbox, pivot pin 5 is through in the hole of above-mentioned two otic placodes, one end of this pivot pin is the major diameter step body, the other end is provided with the hole that matches with split pin, be provided with on the outer flange 2 of the outer flange of case lid 3 lower port and above-mentioned casing upper port with above-mentioned and wave the breach that bolt 6 matches, this waves the bolt lower end is spheroid, the left side of this spheroid, the right side is the plane, the distance on this two plane is less than or equal to the distance between above-mentioned two otic placodes.The above-mentioned bolt that waves is at least respectively established one on surperficial in forward and backward, the left and right of casing, can arrange a plurality of for larger-size sandbox.
Method of operating of the present utility model: the nut 7 that at first each is waved on bolt unclamps, when carrying out pouring molten iron after sand mold places, case lid is placed on casing, to wave one by one the bolt rotation that makes progress is placed in the outer flange breach of casing and case lid port it, and nut is screwed case lid and casing are tightened up, can carry out pouring molten iron, unclamp each nut when getting foundry goods, make and wave bolt disengagement case lid, can remove case lid and get foundry goods.
