Abstract
The invention discloses a milling clamp for flexible and variable thin-wall cylindrical parts, which comprises two matched semicircular hoops, wherein butt-joint holes are formed in two ends of each semicircular hoop, the two semicircular hoops are connected through hoop butt-joint pins, hoop butt-joint bolts and hoop butt-joint nuts to form a circular hoop, mounting holes are formed in the semicircular hoops, and the semicircular hoops are connected with arc-shaped ejector blocks through ejector block mounting bolts and ejector block mounting nuts. The invention solves the problems that when the internal grid is milled due to the deformation of a cylindrical thin-wall part, the alignment of the part is difficult, the thickness of the grid machine is difficult to guarantee due to the roundness change of the part, the milling efficiency of the grid is low, the quality of the part is difficult to guarantee, and the like.
Description
Technical Field
The invention relates to a milling clamp for flexible variable cylinder thin-wall parts.
Background
Due to the characteristic of rigidity, when the cylindrical thin-wall part is subjected to meshing, the cylindrical thin-wall part is influenced by roundness deformation, the alignment of the part is complex, the thickness of the mesh is difficult to ensure, and the machining efficiency is greatly influenced. At present, an optimized process scheme, milling strategy and parameter adjustment and a tool are mainly and comprehensively adopted to constrain a part within a bearable roundness range for processing. The existing common tool mainly adopts uniformly distributed arc-shaped jacking blocks, has certain effect from the practical effect, but still needs to adopt a trial cutting-compensation processing method in the grid milling process, has low processing efficiency and has higher requirement on the skill level of an operator.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a milling clamp for a flexible variable cylinder thin-wall part.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a flexible variable drum thin wall class part mills and cuts anchor clamps, includes two assorted semicircle staple bolts, two semicircle staple bolts both ends all are equipped with the butt joint hole, connect through staple bolt butt joint round pin, staple bolt butt joint bolt, staple bolt butt joint nut, form a circular staple bolt, be equipped with the mounting hole on the semicircle staple bolt, be connected with the arc kicking block through kicking block construction bolt and kicking block construction nut.
As a preferred mode, the arc-shaped jacking blocks are uniformly distributed on the semicircular hoops.
Preferably, the arc-shaped top block is provided with different thicknesses.
Preferably, the ejector block mounting bolt is located on the inner side of the semicircular hoop, and the ejector block mounting nut is located on the outer side of the semicircular hoop.
The invention has the following advantages:
the invention solves the problems that when the internal grid is milled due to the deformation of a cylindrical thin-wall part, the alignment of the part is difficult, the thickness of the grid machine is difficult to guarantee due to the roundness change of the part, the milling efficiency of the grid is low, the quality of the part is difficult to guarantee, and the like.
Drawings
FIG. 1 is a schematic view of a clamp according to the present invention;
FIG. 2 is a schematic view of the structure of the arc-shaped top block of the present invention.
In the figure: 1. the hoop comprises a semicircular hoop, 2 arc-shaped ejector blocks, 3 hoop butt bolts, 4 hoop butt nuts, 5 hoop butt pins, 6 ejector block mounting bolts and 7 ejector block mounting nuts.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example (b):
the utility model provides a flexible variable drum thin wall class part mills and cuts anchor clamps, includes two assorted semicircle staple bolts 1, 1 both ends of two semicircle staple bolts all are equipped with the butt joint hole, connect through staple bolt butt joint round pin 5, staple bolt butt joint bolt 3, staple bolt butt joint nut 4, form a circular staple bolt, be equipped with the mounting hole on the semicircle staple bolt 1, be connected with arc kicking block 2 through kicking block mounting bolt 6 and kicking block mounting nut 7. The arc-shaped top blocks 2 are uniformly distributed on the semicircular anchor ears 1. The arc-shaped top block 2 is provided with different thicknesses. The ejector block mounting bolt 6 is located on the inner side of the semicircular hoop 1, and the ejector block mounting nut 7 is located on the outer side of the semicircular hoop 1.
The working principle of the invention is that two high-rigidity semicircular hoops 1 are connected to form a circular hoop and matched with an arc-shaped jacking block 2 with corresponding thickness to realize quick clamping and constraint of parts, so that the parts are kept in a circular state and prevented from deforming. Two semicircle staple bolts 1 are connected through staple bolt locating pin 5, staple bolt jack bolt 3, staple bolt jack nut 4, and arc kicking block 2 is through kicking block construction bolt 6, kicking block construction nut 7 evenly distributed on semicircle staple bolt 1 surface, through the arc kicking block 2 that uses different thickness in order to adapt to different part diameters to make this frock have stronger flexibility and maintainability. By adopting the scheme of the integral rigid hoop, the deformation of the product is restrained by utilizing the high rigidity of the tool, and the product is directly cut according to a theoretical value after clamping is finished, so that the processing efficiency is greatly improved under the condition of ensuring that the wall thickness of the part is not over-poor; the modularized arc-shaped jacking block 2 is arranged in the semicircular hoop 1, can be adjusted according to the outer diameter of a part, and is made of the same material as the part in order to prevent the electrochemical corrosion of the surface of the part, so that the integral rigidity is not influenced, and the part is not damaged; if the frock produces the deformation in the later stage use, can change partial arc kicking block 2, have good maintenance performance.
The invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.
