Height, securely and reliably, the band that can realize that bar adds and chucking power and clamping range are variable under vacuum conditions bottom out protection
Pneumatic charging mechanism.
In order to solve the above technical problems, the utility model is realized in this way:
Variable clamping range band bottoms out the pneumatic charging mechanism of protection, including cylinder, transmission mechanism and Pneumatic clamping mechanism；Institute
The lower part working end for stating Pneumatic clamping mechanism extends vertically into cylinder；The top of the Pneumatic clamping mechanism is fixed with transmission mechanism
Connect.
As a preferred embodiment, Pneumatic clamping mechanism described in the utility model includes outer tube, cylinder, pull rod, taper
Block and folder；The cylinder is fixed at the top of transmission mechanism；The cylinder is fixedly connected by pull rod and circular cone；It is described
Folder is set on circular cone；The fixed outside for being placed on pull rod of the outer tube.
Further, transmission mechanism described in the utility model includes motor, supporting plate, lead screw and screw；The cylinder and support
Plate is fixedly connected；The screw is inserted into supporting plate by through-hole and connects with supporting plate sliding；It is vertically fixed on the supporting plate
Linear bearing；Guide post is cased in the linear bearing；The linear bearing can be along guide post longitudinal sliding motion.
Further, the utility model is fixed with collision block on the top of the screw；Collision block is corresponded on the supporting plate
Position is fixed with travel switch.
Further, outer tube described in the utility model and cylinder contact site are fixed with dynamic sealing device.
Further, folder described in the utility model includes clip, fixture block and hanger；The hanger is fixed at pull rod
End；The lower removable axis of the clip and hanger connects；The fixture block is fixed at the tip inside of clip.
The utility model structure is simple, and processing and manufacturing is low with maintenance cost, easy for installation, safe and reliable, due to using thick stick
The openings of sizes that clip can be changed by adjusting circular cone initial position for rod principle realizes the bar clamping of 60~180mm diameter,
Clip can also replace specification according to service condition and realize that greater or lesser bar clamps；By changing cylinder pressure and changing cylinder
Diameter adjusts chucking power size and realizes the clamping of 120~300kg bar.Due to fixture block when no matter bar diameter clamps using swing fixture block
Forced rotation is automatically parallel with bar to hold bar tightly, and it is more labor-saving safer with bar contact area to increase fixture block.
