Description
Technical field
A kind of lathe chuck belongs to the lathe chuck auxiliary device with fastener locality adjusting device, is specifically related to guarantee when a kind of secondary is installed the uninfluenced adjustment equipment of fastener.
Background technology
Lathe claims lathe again, is mainly used in processing axle, dish, cover and other have the workpiece of rotary surface, based on cylinder, is to use a widest class lathe in machine-building and the repair factory.Along with enriching constantly of product, complexity and the required precision of parts are all had higher requirement.At the part that lathe is processed, need lift down carry out other PROCESS FOR TREATMENT after, taking the situation of carrying out secondary operations on the lathe more often has generation, however part is taken down will produce when refilling and is debug error, can not satisfy the specification requirement of high-precision part.
Secondary is debug error and be may be summarized to be two aspects, the one, the site error that fastener changes with respect to initial position, the 2nd, the angular error that fastener changes with respect to initial angle if can reduce change in location and angle variation, just can reduce secondary and debug error.The adjustment function of position and angle when yet regrettably, existing lathe is not all debug the jig secondary.
Summary of the invention
In order to address the above problem, the invention discloses a kind of lathe chuck fastener locality adjusting device, not only can adjust the position of fastener in the vertical rotation axis plane, and can adjust the setting angle of fastener, what produce when reducing the fastener secondary and debuging debugs error.
The object of the present invention is achieved like this:
A kind of lathe chuck comprises the shell and the adjustment part that fixedly install with fastener locality adjusting device; Described outer casing end is provided with circular gap, and adjustment part is made up of bar portion and head; Head is rounded down near the connecting portion of bar portion and head, and described radius of corner is identical with the gap radius; Through hole passes adjustment part from the symmetrical centre of bar portion and head; Screw is connected and passes the head points head with head threads symmetrical centre is adjusted in the position; The angle adjustment screw is connected with outer casing screw and passes shell and point to bar portion; Outer casing end gap arranged outside has first magnet, and head is provided with projection, and crowning is provided with second magnet to the first magnet direction position, and described first magnet is opposite with the second magnet relative direction polarity.
Above-mentioned a kind of lathe chuck is threaded with head with fastener locality adjusting device, described position adjustment screw, and the angle adjustment screw is threaded with shell, all adopts fine thread to connect.
Above-mentioned a kind of lathe chuck adopts abrasive polishing process to carry out surface treatment with fastener locality adjusting device, described circular gap and fillet.
Above-mentioned a kind of lathe chuck scribbles lubricating oil with fastener locality adjusting device in the middle of described circular gap and the fillet.
Above-mentioned a kind of lathe chuck fastener locality adjusting device, described first magnet and second magnet are permanent magnet or electromagnet.
Above-mentioned a kind of lathe chuck comprises that with fastener locality adjusting device the different adjustment part of through-hole diameter is a plurality of.
Important breakthrough of the present invention is the design by the combination of accurate screw, magnet and fillet, gap, realize the fine setting of fastener level, upright position and multi-angle direction dexterously, reduce secondary substantially and debug error, realize the high precision of part processing, satisfied the requirement of special-shaped class part precision.Because lathe chuck of the present invention fastener locality adjusting device passes through to adjust the position at the shell that fixedly installs and adjusts screw, realize the position adjustment of fastener in the vertical rotation axis direction, the change in location of fastener when the solution secondary is debug; By adjusting the angle adjustment screw, fillet is rotated in gap, realize the angle adjustment of fastener, the angle of fastener changed when the solution secondary was debug; The unique construction that the two combines makes jig can effectively reduce the error of debuging that the fastener secondary produces when debuging.
Description of drawings
Fig. 1 is lathe chuck of the present invention fastener locality adjusting device cutaway view.
Among the figure: screw, 4 angle adjustment screws are adjusted in 1 shell, 11 first magnet, 2 adjustment parts, 21 bar portions, 22 heads, 23 through holes, 24 projectioies, 25 second magnet, 3 positions.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in further detail.
Specific embodiment one
The lathe chuck of present embodiment fastener locality adjusting device, cutaway view as shown in Figure 1.This fastener locality adjusting device comprises shell (1) and the adjustment part (2) that fixedly installs; Described shell (1) end is provided with circular gap, and adjustment part (2) is made up of bar portion (21) and head (22); (220 connecting portion is rounded down, and described radius of corner is identical with the gap radius for the close bar portion (21) of head (22) and head; Through hole (23) passes adjustment part (2) from the symmetrical centre of bar portion (21) and head (22); Screw (3) is connected and passes head (22) sensing head (22) with head (22) fine thread symmetrical centre is adjusted in four positions that are symmetrically distributed, four the angle adjustment screws (4) that are symmetrically distributed are connected with shell (1) fine thread and pass shell (1) and point to bar portion (21), and adopting the reason of closely-pitched is in order to improve the adjustment precision; Shell (10) end gap arranged outside has first magnet (11), head (22) is provided with projection (24), projection (24) is in the face of first magnet (11) direction position, be provided with second magnet (25), described first magnet (11) and second magnet (25) are the permanent magnet of annular, and relative direction polarity is opposite, by attracting each other between first magnet (11) and second magnet (25), gap is remained with fillet to be contacted, be used for adjusting the angle of adjustment part (2), and then adjust the angle of fastener.Described circular gap and fillet adopt abrasive polishing process to carry out surface treatment, and scribble lubricating oil in gap and fillet centre, not only can improve the angle adjustment precision, and the creeping phenomenon that produces when preventing angle adjustment between gap and the fillet.
