Description
Technical field
The utility model relates to a kind of sleeve workpiece clamping and fixing device.
Background technology
Existing sleeve workpiece clamping and fixing device is provided with location holder, locating shaft, guide holder and power source, locating shaft is fixed on power source, power source is fixed on guide holder, when work, cover base part is enclosed within on locating shaft, power source provides power drive locating shaft and sleeve workpiece motion and contact with holder, thereby the clamping that realizes cover base part is with fixing.
Because the locating shaft of above-mentioned clamping and fixing device is of a size of fixed, therefore in the time setting the fit clearance of sleeve workpiece and locating shaft, just need to consider that the mismachining tolerance of sleeve workpiece and cover base part can produce micro-deformation amount in welding process, therefore this gap value can be larger, thereby have a strong impact on the positioning precision of sleeve workpiece.
Summary of the invention
In order to overcome the low precision that is fixedly clamped of existing sleeve workpiece clamping and fixing device, the deficiency of pickup difficulty, the utility model provide one to be fixedly clamped precision is high, pickup be easy to sleeve workpiece clamping and fixing device.
The utility model solves the technical scheme that its technical problem adopts:
A kind of sleeve workpiece clamping and fixing device, comprise holder, locating shaft, guide holder and power source, described locating shaft is sleeved in the pilot hole of described guide holder slidably, described power source is fixed on described guide holder, described locating shaft comprises stiff end and positioning end, the power output shaft of described power source is connected with described stiff end, sleeve workpiece is sleeved on described positioning end, the side that described holder is relative with described positioning end is provided with uses the groove stretching into for described positioning end front end, described clamping and fixing device also comprises the head that rises, the described head that rises is fixed in described groove, described rise head center line and the axis of described locating shaft be positioned on same straight line, described positioning end is hollow flap elastomer, the described minimum outer diameter that rises by head is less than the internal diameter of the end of described positioning end, maximum inner diameter when the described maximum outside diameter that rises by head is greater than the end spreading of described positioning end.
Further, described bottom portion of groove is installed and is adjusted packing ring, and head rises described in installing on described adjustment packing ring.
Further, described adjustment packing ring has at least two, adjusts the packing rings layout that superposes up and down at least two.
Further, the end of described positioning end is provided with the conical surface.
The beneficial effects of the utility model are mainly manifested in: simple in structure, compact, easy to operate, and effectively solved the problem such as the low precision that is fixedly clamped, pickup difficulty causing due to factors such as sleeve workpiece mismachining tolerance, welding deformations in welding process.
Brief description of the drawings
Fig. 1 is a kind of structural representation of sleeve workpiece clamping and fixing device.
Fig. 2 is the structural representation of locating shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1～Fig. 2, a kind of sleeve workpiece clamping and fixing device, comprise holder 1, locating shaft 2, guide holder 3 and power source 4, described locating shaft 2 is sleeved in the pilot hole of described guide holder slidably, described power source 4 is fixed on described guide holder 3, described locating shaft 2 comprises stiff end 21 and positioning end 22, the power output shaft of described power source 4 is connected with described stiff end 21, sleeve workpiece 7 is sleeved on described positioning end 22, the side that described holder is relative with described positioning end 22 is provided with uses the groove stretching into for described positioning end 22 front ends, described clamping and fixing device also comprises and rises 6, described rising 6 is fixed in described groove, a described center line of 6 and the axis of described locating shaft 2 of rising is positioned on same straight line, described positioning end 22 is hollow flap elastomer, described 6 the minimum outer diameter of rising is less than the internal diameter of the end 23 of described positioning end 22, maximum inner diameter when described 6 the maximum outside diameter of rising is greater than end 23 spreading of described positioning end 22.
Further, described bottom portion of groove is installed and is adjusted packing ring 5, rises 6 on described adjustment packing ring 5 described in installing.
Further, described adjustment packing ring has 5 at least two, adjusts packing rings 5 layout that superposes up and down at least two.
Further, the end 23 of described positioning end 22 is provided with the conical surface.
In the present embodiment, positioning end 22 diameter of described locating shaft 2 can regulate by adjustment 6 position of rising.
Operation principle of the present utility model is: sleeve workpiece 7 is enclosed within the positioning end 22 of locating shaft 2, power source 4 is worked, drive locating shaft 2 and workpiece 7 to move to holder 1 along guide holder 3, the end face 23 of the positioning end 22 of locating shaft 26 contacts spreading and clamps with rising, workpiece 7 compresses with holder 1 end contact, realizes reliable and stable being fixedly clamped of sleeve workpiece 7 (thickness that can adjust packing ring 5 according to the processing dimension situation utilization increase and decrease of workpiece 7 is adjusted locating shaft 2 and risen by opportunity that contacts of 6).Workpiece 7 completes after weld job under this is fixedly clamped state, power source 4 reverse operations, drive locating shaft 2 and rise 6, workpiece 7 departs from, because the positioning end 22 of locating shaft 2 is hollow flap elastomer, 6 departing from moment locating shafts 2 positioning end 22 size decreases with rising, greatly reduce the resistance that locating shaft 2 and workpiece 7 depart from, thereby solved the problem that causes pickup difficulty due to welding deformation.The end 23 of the positioning end 22 of locating shaft 2, owing to often contacting with 6 impact of rising, therefore be designed to the conical surface, extends its service life.
