Abstract
The invention discloses a clamp for machining a molded line of a scroll plate, and relates to the technical field of equipment of mechanical machining processes. The clamp comprises a base of which the top surface is provided with a middle hole, wherein a lower end plate is fixedly connected to the bottom of the base; at least three pressing arms are distributed at the periphery of the middle hole in the top surface of the base and are connected to the base by hinged shafts; each pressing arm is hinged with a pressing arm driving cylinder; positioning pins are arranged on the top surface of the base; each pressing arm is hinged to a lug plate which extrudes out of a connecting ring; and the connecting rings are sleeved outside the upper end of the base and are fixedly connected with the base by bolts. Compared with the prior art, the clamp has the advantage that the scroll plate is clamped on the vertical machining center to be subjected to the machining of the molded line, so that the surface roughness, profile tolerance and dimensional accuracy of the molded line can meet the design requirement, the quality is ensured, and the production cost is saved.
Description
Technical field
The present invention relates to Machining 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, scroll plate have an end plate and on vortex wall.Screw compressor is during by two intermeshing scroll plate relative motions to the compression of gas, and the passing of the potted line ecto-entad of the vortex wall of two scroll plate realizes.Therefore the accuracy of manufacture of scroll plate molded line directly has influence on the service behaviour of screw compressor, and the processing of scroll plate molded line is high especially to the requirement of equipment, and it is mostly to carry out on special processing equipment that early stage people process scroll plate, and equipment and processing charges are extremely expensive.In recent years, development along with Computerized Numerical Control processing technology, especially the raising of machining center precision and performance, the molded line of scroll plate adopts vertical machining centre equipment to process becomes possibility, but a kind of being suitable for scroll plate clamping fixture with convenience and assurance crudy on vertical machining centre not yet arranged at present.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of scroll plate profile processing fixture, and this scroll plate profile processing fixture can carry out profile processing in vertical machining centre to it with the scroll plate clamping.
The technical scheme that technical solution problem of the present invention adopts is: this scroll plate profile processing fixture includes the base that an end face is provided with interstitial hole, the bottom of described base is fixedly connected with bottom plate, be distributed with at least three pressure arms around the interstitial hole of described base top surface, these three pressure arms all are connected on described base by jointed shaft, each described pressure arm is hinged with respectively a pressure arm and drives cylinder, and described base top surface is provided with alignment pin.
The technical scheme of above-mentioned scroll plate profile processing fixture, can also be more specifically: described each pressure arm be to be hinged on stretching out in otic placode on a connecting ring, described connecting ring is sleeved on outside the upper end of described base, and described connecting ring is fixedly connected with described base by bolt.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect that has is: the scroll plate clamping can be carried out the processing of molded line to it by this fixture on vertical machining centre, the surface roughness of molded line, profile tolerance and dimensional accuracy all reach designing requirement, ensure the quality of products, save production cost.
Description of drawings
Fig. 1 is the top view of the embodiment of the present invention.
Fig. 2 is the cutaway view at the A-A place of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Scroll plate profile processing fixture includes the base 4 that an end face is provided with interstitial hole as shown in Figure 1 and Figure 2, the bottom of base 4 is fixedly connected with by interference fit with bottom plate 6, be distributed with three pressure arms 1 around the interstitial hole of base 4 end faces, these three pressure arms 1 all are connected on base 4 by jointed shaft, each pressure arm 1 is hinged with respectively a pressure arm and drives cylinder 5, each pressure arm 1 is to be hinged on stretching out in otic placode on a connecting ring 2, connecting ring 2 is sleeved on outside the upper end of base 4, and connecting ring 2 is fixedly connected with base 4 by bolt 7; Base 4 end faces are equipped with two alignment pins 3.
Pressure arm 1 of the present invention can also be four, and each pressure arm 1 respective hinge has a pressure arm to drive cylinder 5.
During work, compress bottom plate 6 with T-shaped slot bolt scroll plate profile processing fixture is fixed on the workbench of vertical machining centre; Check ring is packed in the annular groove of scroll plate end plate cylindrical, and the vortex wall section of scroll plate upwards is contained in the end face of base 4, and two alignment pins 3 plug-in mounting respectively enter the phase place of fixed scroll in the elongated slot of scroll plate end plate bottom; Three pressure arms 3 are placed on the check ring end face, start pressure arm and drive cylinder 5, the scroll plate compression can be begun to carry out the processing of molded line.
