The utility model content
The technical problems to be solved in the utility model provides that a kind of to adopt linear bearing guiding and main body rack be the insert-pull pin mechanism of open by design, and it is reliable to guarantee that not only its serviceability is promptly moved smooth and easy accurate positioning; And guarantee that its maintainability well is conveniently assembly and disassembly of inner body.
In order to solve the problems of the technologies described above, this practicality newly provides following technical scheme:
A kind of insert-pull pin mechanism that is used on weld jig workpiece hole face location, it comprises a location pin assemblies and a main body rack, this pin assembly is by cylinder, the cylinder connecting rod, lead and the alignment pin formation that is assembled together successively, wherein said cylinder connection piece links to each other with described cylinder, described alignment pin inserts in the centre bore of described lead and by a fixture and is fastened in this centre bore, described lead removably links to each other with described cylinder connection piece, described cylinder is fastened on the described main body rack, described pin assembly inserts and is installed in the support unit of described main body rack, described support unit is positioned at around the described lead
Described main body rack is an Open architecture, and when dismantling described pin assembly with box lunch, described pin assembly can separate from the side with on the described main body rack.
Preferably, described main body rack is made of the vertical support unit and the horizontal support member that are perpendicular to one another, described support unit is installed in the described vertical support unit, described horizontal support member is used to install described cylinder, has the elongated gap of width greater than described lead on described horizontal support member.
Preferably, described support unit is a linear bearing.
Preferably, also comprise a protective cover, it can be installed on the described main body rack to form enclosure space.
Preferably, described fixture is a jackscrew.
Preferably, described cylinder is installed by magnetic switch, is used for detecting cylinder and is in and stretches out or retracted mode when work.
Characteristics of the present utility model are accurate positionings, and are simple in structure, easy to maintenance.Can be used as standard portion product is widely used in robot welding system and the manual welding system.
After adopting insert-pull pin of the present utility model mechanism, make this mechanism's alignment pin expanding-contracting action smooth and easy, long-time accurate positioning is reliable, adopted alignment pin to be fixed on the guide rod, by the structure of linear bearing guiding, linear bearing guiding accuracy height, friction mode is rolling friction, resistance is little, move smooth and easy, and long service life.The open design that the main body rack of this mechanism adopts.The side of the horizontal support member of the installation cylinder on the main body rack has the gap of width greater than the cylinder shank diameter, can make things convenient for the dismounting of cylinder; Dodge the diameter of the bore dia of cylinder bar on the horizontal support member, guide rod is extracted out very easily greater than the maximum position of guide rod; The mounting screw of locating surface is arranged in the outside, easily dismounting; Alignment pin takes off the back at locating surface and only need twist one and hold out against screw and just can change very easily.According to above design each part in the assembling can both be loaded and unloaded very easily, reached the short purpose of maintenance time.
