[ background of the invention ]
The working table of the vertical lathe used by the current pump industry factory is at least 800mm, and the minimum diameter of the inner hole of the part which can be tightened by four claws on the chuck is more than 200 mm. The centrifugal pump shell is an eccentric part, and the machining of a through hole or a spigot, an end face and an inlet flange of the centrifugal pump shell is usually completed on a vertical lathe, but the centrifugal pump shell cannot be machined on a vertical lathe because the diameter of the through hole or the spigot is less than 200mm, and is usually machined on a horizontal lathe. When the shell end face and the via hole or the spigot are machined on a horizontal lathe, the centrifugal pump shell is an eccentric part, meanwhile, a balance device is difficult to install on a horizontal lathe chuck, the distance from a clamping inlet flange to a cantilever of the shell end face is long, the clamping rigidity is poor, a workpiece is easy to vibrate when rotating, and the size precision, the form and position tolerance and the surface roughness of the centrifugal pump shell end face and the via hole or the spigot are difficult to guarantee. In order to meet the requirements of size precision, form and position tolerance and surface roughness of the end face of the shell and the through hole or spigot, the rotating speed of a workpiece needs to be reduced, and clamping and turning need to be carried out more than 3 times. Therefore, the clamping and alignment for multiple times are time-consuming, the machining precision is low, the efficiency is low, and the manufacturing cost is increased.
Therefore, the problem to be solved in the field is to provide a machining device for a centrifugal pump shell with a hole or a spigot with the diameter smaller than 200 mm.
[ Utility model ] content
To the above problem, the utility model discloses centrifugal pump shell processingequipment is through increasing anchor clamps between the chuck and waiting to process the casing to this solves the clamping difficult problem of the centrifugal pump shell that hole or tang diameter are less than 200mm on vertical lathe, and the clamping rigidity is strong, can satisfy size precision, form and position tolerance, roughness's requirement, improves production efficiency, reduction in production cost.
In order to solve the problem, the utility model discloses centrifugal pump shell processingequipment includes the lathe, installs knife rest and anchor clamps on the lathe, the lathe includes the main shaft and installs the epaxial chuck of main, anchor clamps are including pressing from both sides the anchor clamps body, disc and the closing device of pressing from both sides tight in the chuck, the upper and lower both ends of the anchor clamps body have round platform and lower round platform, the disc passes through the mounting screw on last round platform, closing device includes clamp plate and clamp bolt, will wait to process the casing and compress tightly between chuck and clamp plate through closing device.
Furthermore, the pressing plate is of a structure shaped like a Chinese character 'jing' and is placed on the upper end face of the shell to be processed, four pressing bolts are respectively connected to four corners of the pressing plate, and nuts are connected to the pressing bolts after the pressing bolts penetrate through the pressing plate.
Further, one end of the pressing bolt is screwed on the chuck.
Furthermore, the utility model discloses centrifugal pump shell processingequipment is through increasing anchor clamps between the chuck and treating to process the casing to this solves the hole or tang diameter and is less than the difficult problem of 200 mm's centrifugal pump shell clamping on vertical lathe, and the clamping rigidity is strong, can satisfy size precision, form and position tolerance, roughness's requirement, improves production efficiency, reduction in production cost.
