Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 2, 3 and 4, the utility model provides a centrifuge shell electric spark processing clamping mechanism, which comprises a connecting shaft 2 connected on a machine tool main shaft 1, the main shaft is connected with the connecting shaft 2 through a flange, an air suction cavity 3 is arranged on the connecting shaft 2, an air suction plate 4 is connected on the air suction cavity 3, external threads are arranged outside the air suction cavity, internal threads are arranged on the air suction plate 4, the connection is realized by screwing the air suction plate and the air suction plate, densely distributed air suction holes 5 are arranged in the center of the air suction plate 4, a rubber ring 6 is arranged on the air suction holes 5 and corresponds to the position of an air suction cavity, a vacuum generating device 12 is arranged on the hollow cavity, namely, the housing can be absorbed by the air suction holes 5 on the air suction plate 4 through the negative pressure formed in the air suction cavity, because the surface of the shell is polished, the shell can be adsorbed and positioned by the air suction plate 4. And because the shell is a circular piece and needs to be driven by the rotation of the main shaft of the machine tool when the hole is punched on the circumference, the shell must be centered, otherwise the punching position is difficult to be uniform, and at least three groups of telescopic centering limit rods 7 are arranged around the air suction plate 4.
Specifically, as shown in fig. 2, the centering limit rod 7 includes a first rod sleeve 8, a second rod sleeve 9 is disposed in the first rod sleeve 8, a rod body 10 is disposed in the second rod sleeve 9, a blocking piece 11 is disposed at an end portion of the rod body 10, the blocking piece 11 is disposed perpendicular to the rod body 10, diameters of the first rod sleeve 8 and the second rod sleeve 9 are gradually reduced, the second rod sleeve 9 can be pulled out from the first rod sleeve 8 and clamped at an end portion of the first rod sleeve 8, the rod body 10 can also be pulled out from the second rod sleeve 9 and can rotate the rod body 10, at least three positioning rods are disposed, a round, preferably uniformly arranged positioning rod can be positioned, a processing shell is pressed on the air suction plate 4 instead of the air suction plate, and the blocking piece 11 is pressed on an outer wall of the shell between the blocking pieces 11 of the positioning rods, since the centering limit rod 7 is of a fixed length, after the centering limit rod 7 is completely pulled out, the circle center of the shell clamped between the three centering limit rods 7 is always at the center of the connecting shaft 2, so that centering is realized, and the stability of the punching position is ensured during rotation.
A clamping block is arranged on the lower portion of the first rod sleeve 8, a clamping groove 14 is formed in the air suction plate 4, and the clamping block is clamped in the clamping groove 14, so that the centering limiting rod 7 can be conveniently dismounted.
In addition, because the negative pressure effect, when changing the product, there is partial liquid to get into, so induced draft accent portion of a housing is equipped with activated carbon layer 13, through setting up to the cavity that the outer wall is the dictyosoid, fill activated carbon in the cavity, induced draft accent portion of a housing inner wall is equipped with protruding edge, the cavity that the activated carbon constitutes is pressed on protruding edge, when induced draft board 4 with induced draft the chamber when revolving, induced draft board 4 is pressed on activated carbon layer 13, add man-hour when the good product of location, through the effective separation moisture entering of activated carbon layer 13, prevent to damage negative pressure generating device, and activated carbon can regularly change, only need to induced draft board 4 from induced draft the chamber department to revolve down change can.
Various modifications to the embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
