Abstract

The utility model discloses a toothed plate positioning device and relates to the technical field of machining process technological equipment. The device comprises a disc base with a middle hole formed in the top surface, wherein the disc base is fixed on a base through a cylindrical base, at least three upwards oblique holes are distributed on the periphery of the middle hole in the top surface of the disc base, a toothed plate positioning device body is arranged on each oblique hole and comprises a telescopic rod with one end stretching out of the top surface of the disc base through the oblique holes, a pressing plate is arranged on the tip of the stretching-out end of each telescopic rod, a pressing nail is arranged on the lateral side, close to the middle hole, of each pressing plate, each pressing nail is provided with a working surface where a plurality of protrusions are distributed, the other end of each telescopic rod is hinged to a transition part through a chain link and a pin shaft, and the transition part is connected with a lifting oil cylinder. Compared with the prior art, the device has the advantages that the problem that an existing scroll plate molded line machining clamp is not firm in clamping and poor in machining accuracy is solved.

Description

Tooth plate positioner
Technical field
The utility model relates to machining equipment technology field, especially a kind of fixture for the molded line of Machining of Vortex Disk of Vortex Compressor is processed.
Background technology
The core component of screw compressor is scroll plate, and scroll plate has an end plate and establishes vortex wall thereon.Screw compressor is during by two intermeshing scroll plate relative motions to the compression of gas, the passing of the potted line ecto-entad of the vortex wall of two scroll plate realizes, so the accuracy of manufacture of scroll plate molded line directly has influence on the service behaviour of screw compressor.Have a kind of tooth plate positioner, this tooth plate positioner includes the disc seat that an end face is provided with interstitial hole, and described disc seat is fixed on base by cylinder seat; Surrounding at the interstitial hole of described disc seat end face is distributed with at least three pressure arms; Scroll plate molded line is added to man-hour, and its step is first jump ring to be packed in the annular groove that the end plate outer rim of scroll plate offers, then scroll plate is packed in centre bore, by pressure arm, the compression of jump ring is fixed on scroll plate on disc seat; Then by milling cutter, the molded line of scroll plate is processed.In use there are the following problems for this processing method: 1,, owing to being that termination by pressure arm applies a downward power to the jump ring in annular groove and is fixed to scroll plate fastening, clamping is firm not; 2, annular groove has gap, and in process, part easily play occurs and affects the machining accuracy of scroll plate molded line.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tooth plate positioner, and this tooth plate positioner can solve the insecure and poor problem of machining accuracy of existing scroll plate profile processing fixture clamping.
The technical scheme that the utility model technical solution problem adopts is: this tooth plate positioner comprises that an end face is provided with the disc seat of interstitial hole, described disc seat is fixed on base by cylinder seat, surrounding at the interstitial hole of described disc seat end face is at least distributed with three inclined holes that are tilted to, described in each, on inclined hole, be equipped with tooth plate positioner, described tooth plate positioner comprises that one end is from the expansion link of the described disc seat end face of stretching out of described inclined hole, described expansion link is provided with pressing plate in its external part termination, described pressing plate is provided with nail pressing in the side of nearly centre bore, described nail pressing has the working face that is distributed with a plurality of projections, the other end of described expansion link is hinged on transition piece by chain link and bearing pin.
The technical scheme of above-mentioned tooth plate positioner, can also be more specifically: the protruding angle of the described projection that described nail pressing working face distributes is 90 degree.
Further, between described nail pressing and the side of described pressing plate, be provided with adjusting pad.
Owing to having adopted technique scheme, the utility model compared with prior art, the beneficial effect having is: this fixture is by a plurality of nail pressings, directly to clamp the cylindrical of end plate to the clamping of scroll plate, and nail pressing is contained in expansion link one end by pressing plate, expansion link oblique cutting is on the inclined hole of disc seat, the other end of expansion link is hinged on transition piece by chain link, and transition piece is connected with hoist cylinder; During clamping, scroll plate to be processed is placed on the centre bore of disc seat, starting hoist cylinder moves downward, nail pressing is along with oblique lower inwardly the tightening when moving moving of transition piece clamps the end plate cylindrical of scroll plate, now, bite at end plate cylindrical is subject to a downward power and a radially effect for internal force simultaneously, and under the force action of these two power, scroll plate is firmly clamped on disc seat; At profile processing process mesoscale eddies dish, can not produce play phenomenon, good stability, machining accuracy is high.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment 1:
Tooth plate positioner as shown in Figure 1 and Figure 2 comprises that an end face has the disc seat 4 of interstitial hole, and 4 of disc seats are contained on cylinder seat 3, and cylinder seat 3 is bolted on base 1; The present embodiment is distributed with three inclined holes that are tilted in the surrounding of the interstitial hole of disc seat 4 end faces, and the oblique angle a of inclined hole is 58 degree; Tooth plate positioner is all housed on each inclined hole, tooth plate positioner comprises that one end is from the expansion link 10 that stretches out disc seat 4 end faces of inclined hole, expansion link 10 is equipped with pressing plate 9 in its external part termination, pressing plate 9 is equipped with nail pressing 7 on the side of the centre bore of nearly disc seat, nail pressing 7 has the working face that is distributed with a plurality of projections, and the protruding protruding angle distributing on the working face of nail pressing 7 is 90 degree; Between nail pressing 7 and the side of pressing plate 9, be provided with adjusting pad 8, to adapt to the needs of the scroll plate 6 of processing different size; The other end of expansion link 10 is hinged on transition piece 5 by chain link 11 and bearing pin, and transition piece 5 is fixed on by screw rod 12 on the piston rod of hoist cylinder 2, and hoist cylinder 2 is bolted on the base 1 in cylinder seat 3.
During work, scroll plate to be processed 6 is placed on the centre bore of disc seat by locating shaft, start hoist cylinder to 2 times motions, nail pressing 7 is along with oblique lower inwardly the tightening when moving moving of transition piece 5 clamps scroll plate 6 end plate cylindricals, now, on the bite of end plate cylindrical, be subject to a downward power and a radially effect for internal force, under the force action of these two power, scroll plate 6 is firmly clamped on disc seat 4, can start to carry out the processing of molded line simultaneously; At profile processing process mesoscale eddies dish, can not produce play phenomenon, good stability, machining accuracy is high.
