Abstract
The utility model relates to a clamping device of a crank-connecting rod and provides a clamping device of a connecting rod of a thermal burring machine. The clamping device of the connecting rod of the thermal burring machine comprises a guide sleeve, a mandril, an isometric connecting rod, a base, a fixed seat, and a thrust cylinder, wherein the number of isometric connecting rods is two, one end of a first isometric connecting rod and one end of a second isometric connecting rod are connected with a link pin, the link pin is connected with an movable end of the thrust cylinder, the other end of the first isometric connecting rod is connected with the fixed sear through another link pin, the other end of the second isometric connecting rod is connected with one end of the mandril in a vertical state through a third link pin, the other end of the mandril is provided with the guide sleeve and connected with the base, and the base is arranged below the base of a combustor of the thermal burring machine. The clamping device of the crank-connecting rod of the thermal burring machine is tight in structure, simple and efficient, convenient to assemble and maintain, and stable in performance, so that a potential safety hazard is effectively solved because a device failure is less than explosive force and hot air is ejected between the combustor and the base.
Description
Technical field
The utility model relates to a kind of toggle clamping device, a kind of specifically thermal deburring bed toggle clamping device.
Background technology
The thermal deburring bed is to utilize combustion gas and oxygen mix igniting back implode in the combustion chamber, and the HTHP that utilizes blast to produce is burnt the burr on the workpiece in the combustion chamber.Explosion time will produce the inside that huge explosive force acts on the combustion chamber, approximately 40MPa.If act between combustion chamber and the base thrust because of equipment fault less than explosive force, red-hot air-flow just possibly from spraying between combustion chamber and the base, with producing serious consequence.This just requires the clamping device between combustion chamber and the base reliable and stable.
Summary of the invention
The utility model technical problem to be solved is: a kind of thermal deburring bed toggle clamping device is proposed, and compact conformation, simple efficient, stable performance is assembled easy to maintenancely, guarantees the safety of equipment.
The technical scheme that the utility model solves above technical problem is:
Thermal deburring bed toggle clamping device; Comprise fairlead, push rod, equidistance connecting rod, base, holder and propelling oil cylinder; The equidistance connecting rod is provided with two, an end of the first equidistance connecting rod and the second equidistance connecting rod link pin that all links to each other, and link pin connects the movable end that advances oil cylinder; The other end of the first equidistance connecting rod connects holder through another link pin; The other end of the second equidistance connecting rod connects an end of the push rod that is vertical state through the 3rd link pin, and the other end of push rod is provided with fairlead and connects base, and base is positioned at thermal deburring bed combustor base below.
The technical scheme that the utility model further limits is:
Aforesaid thermal deburring bed toggle clamping device, the angle of two equidistance connecting rods changes between 36 degree and 180 degree.
The utility model has the advantages that: the utility model uses an oil cylinder to accomplish mechanical action, has realized that simultaneously the direction of power changes, active force and stroke amplification, and mechanical interlocking more helps the overall structural arrangement of thermal deburring bed; The utility model compact conformation, simple efficient, assemble easy to maintenancely, stable performance can effectively solve the serious potential safety hazard that the red-hot air-flow that causes less than explosive force because of equipment fault goes out from injection between combustion chamber and the base.

The specific embodiment
Embodiment one
Present embodiment is a kind of thermal deburring bed toggle clamping device; Comprise fairlead 1, push rod 2, equidistance connecting rod 3, base 5, holder 8 and advance oil cylinder 7; The equidistance connecting rod is provided with two; The end of the first equidistance connecting rod 3A and the second equidistance connecting rod 3B link pin 4 that all links to each other; Link pin 4A connects the movable end that advances oil cylinder 7, and the other end of the first equidistance connecting rod 3A connects an end of the push rod 2 that is vertical state through the 3rd link pin through the other end of another link pin 4B connection holder 8, the second equidistance connecting rod 3B; The other end of push rod 2 is provided with fairlead 1 and connects base 5, and base 5 is positioned at thermal deburring bed combustor base 6 belows.
The angle that advances oil cylinder to drive two equidistance connecting rods changes between 180 degree and 36 degree, thereby the push rod that drives slides up and down along guide pin bushing, and at this moment the push rod upper end promotes base, and makes it to realize the airtight of combustion chamber and open.The angle of two equidistance connecting rods is when 180 spend, and combustion chamber and base are in air-tight state.Mechanism kinematic is to the dead-centre position this moment, and beginning is transformed into mechanical force by the thrust that advances oil cylinder to produce.Advance the oil cylinder oil pressure to reduce even equipment fault this moment makes, can not change the combustion chamber and base is in air-tight state, guarantee the safety of equipment.The utility model uses an oil cylinder to accomplish this mechanical action, has realized that simultaneously the direction of power changes, and active force amplifies with stroke, and mechanical interlocking more helps the overall structural arrangement of lathe, and compact conformation simply efficiently, assembles easy to maintenance.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of the utility model requirement protection.
