The utility model content
The technical problems to be solved in the utility model provides a kind of simple to operate and once clamp the processing check valve screw vehicle clamper that just can realize four screw Vehicle Processings.
For solving the problems of the technologies described above, the processing check valve screw that provides comprises the work supporting block that can be connected on the lathe chuck with vehicle clamper, its design feature is: be connected with the supporting plate that can vertically slide on the work supporting block, the locking device of locking supporting plate is housed on the work supporting block, horizontal longitudinal sliding motion is connected with the locking device of lower plate and locking lower plate on the supporting plate, lower plate is provided with workpiece jack and workpiece alignment pin, be fixed with the lead that two parallel interval arrange on the lower plate, the top movable of lead is connected with the train wheel bridge of corresponding setting with lower plate, be bolted with pressure head on the train wheel bridge, the inner extending end of pressure head is equipped with the briquetting that adapts to the workpiece end face.
Vertical both sides of described supporting plate are fixed with the slideway that two levels are oppositely arranged, and lower plate has along the slide rail that inserts in the slideway and slide along slideway, and described locking device is the lock(ing) bolt that is screwed onto on the slideway.
Baffle plate is equipped with respectively in the front and back end section of supporting plate, is bolted with caging bolt on the baffle plate.
Work supporting block comprises disk and the clamp holder that is packed on the disk, and described supporting plate is connected on the disk.
Described disk is provided with at least vertical chute that arranges of twice, and described locking device is the clamping screw that is screwed onto on the supporting plate and passes chute.
When the processing oil transportation screw of employing said structure machines with vehicle clamper, train wheel bridge is removed from the column top of leading, workpiece (being fuel supply pump housing) is placed between train wheel bridge and the lower plate, accurately locate by workpiece jack and alignment pin the bottom of workpiece, by screwing pressure head workpiece firmly is fixed between briquetting and the lower plate, this work supporting block is contained on the lathe, moving horizontally lower plate also fixes by locking device and locking device respectively with vertical mobile pallet, make lathe tool aim at one of them check valve screw, can realize the Vehicle Processing to one of them the check valve screw on the fuel supply pump housing, after process finishing, fix by locking device after unclamping locking device and moving horizontally the lower plate certain distance, can machine another check valve screw, in like manner, vertical mobile pallet and transverse shifting supporting plate can be realized in addition two the Vehicle Processing of check valve screw of fuel supply pump housing, employing once clamps the Vehicle Processing that can realize four check valve screws like this, thereby operation is very simple, the Vehicle Processing of four check valve screws is to machine at same datum level, thereby avoided occurring check valve screw center and do not aligned up and down, the phenomenon that level is not concordant, product percent of pass improves greatly, reduced workman's operation easier, efficiency is high and saved production cost.
In sum, the utlity model has simple to operate and once clamp the advantage that just can realize four screw Vehicle Processings.
