Description
Technical Field
The utility model relates to a processing technology technical field of tubulose work piece specifically is a car processing location frock for reducing pipe fitting hole deformation.
Background
In the traditional turning mode, the outer circle of a part is clamped by three claws of a lathe or a liner clamping sleeve is additionally arranged on the outer circle, so that the clamping force is reduced, the influence of clamping force on the inner hole is reduced, the deformation of the inner hole is kept small, the sleeve needs to be sleeved on the excircle of the workpiece before the processing, the excircle needs to be well matched, the consistency of the excircle is required to be good, when in processing, the part sleeved with the clamping liner is placed into the three claws of the machine tool, after the part is processed, the part and the clamping sleeve are taken down together, in the whole processing process, the auxiliary time is long, the efficiency is low, the inner hole of the processed part is changed by about 0.005mm, for tubular workpieces with higher requirements on the precision of the inner hole, the traditional turning is adopted to process the sizes of the excircle, the length and the like, except for clamping the excircle corresponding to the high-precision inner hole, no other clamping parts exist, the clamping of the outer circle can cause the deformation of the inner hole, and the processing mode is not suitable for tubular workpieces with high precision.
SUMMERY OF THE UTILITY MODEL
To the defect among the prior art, the utility model provides a car processing location frock for reducing pipe fitting hole deformation, this frock can effectively solve the problem that pipe fitting hole deformation and machining efficiency are low, is applicable to the tubulose, and the higher work piece of hole required precision prevents to lead to the condition of hole deformation because the clamping-force that the centre gripping excircle produced.
A car processing location frock for reducing pipe fitting hole is out of shape, including at least three and lathe chuck fixed mounting's interior chuck, every interior chuck all includes the canned paragraph and the support section of perpendicular setting, the canned paragraph is used for being connected with the lathe chuck, the support section is the arc axle, and when interior chuck all inwards closed, the arc axle forms the cylinder, and its outer diameter is less than the hole diameter of pipe fitting, makes and waits to process the pipe fitting assembly on the cylinder, when interior chuck all outwards opens, the inner hole wall of waiting to process the pipe fitting is hugged closely to the outer peripheral face of arc axle for support and fixed pipe fitting.
Furthermore, before the pipe fitting is lathed, one end of the pipe fitting is opened by an inner chuck fixedly mounted on a lathe chuck to support the inner hole wall of the pipe fitting for positioning, and the other end of the pipe fitting is propped against the pipe fitting for positioning by a thimble.
The utility model has the advantages that:
1. by designing the special lathe machining auxiliary positioning tool, one end of the inner chuck is fixedly installed with the lathe chuck, the other end of the inner chuck is designed into a circular arc shaft, and the inner hole wall of the pipe fitting is supported in an opening mode, so that the condition that the inner hole is deformed due to clamping force generated by clamping an outer circle is effectively prevented;
2. the pipe fitting is positioned only through the inner clamping head and the ejector pin, the precision and the size of an inner hole of the pipe fitting are not affected, the auxiliary machining time is reduced, and the turning efficiency is improved.

FIG. 2 is a schematic structural view of the inner clamping head of the present invention;
fig. 3 is a schematic structural view of the positioning pipe fitting of the present invention.
In the drawings: 1-pipe fitting, 2-inner clamping head, 3-thimble,
201-fixed section, 202-support section.
Detailed Description
The embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
By taking an inner hole as an example, the requirement for precision is high, the excircle needs to be clamped and the excircle is turned or the full length is cut, the inner hole of the pipe fitting 1 to be processed is a spline, the precision requirement is high, the excircle and the full length need to be turned after rotary swaging, if the excircle of the inner spline is directly clamped, the inner hole can be deformed, the inner hole can be influenced even if the inner clamping container is additionally arranged, the inner hole is changed by 0.005-0.01mm, and customer assembly is influenced.
In order to solve the problems of deformation of an inner hole and deformation of an outer circle of the inner hole, low efficiency and long auxiliary time, a turning positioning tool for reducing deformation of the inner hole of a pipe fitting, which is shown in fig. 2 to fig. 3, is designed, and comprises at least three inner chucks 2 fixedly mounted with a lathe chuck, each inner chuck 2 comprises a fixing section 201 and a supporting section 202 which are vertically arranged, the fixing section 201 is used for being connected with the lathe chuck, the supporting section 202 is an arc-shaped shaft, when the inner chucks 2 are all closed inwards, the arc-shaped shaft forms a cylinder, the diameter of the outer circle of the arc-shaped shaft is smaller than the diameter of the inner hole of the pipe fitting 1, so that the pipe fitting 1 to be machined is assembled on the cylinder, and when the inner chucks 2 are all opened outwards, the outer peripheral surface of the arc-shaped shaft is tightly attached to the inner hole wall of the pipe.
Before the pipe fitting 1 is lathed, one end of the pipe fitting 1 is opened by an inner chuck 2 fixedly installed on a lathe chuck to support the inner hole wall of the pipe fitting for positioning, and the other end of the pipe fitting is propped against the pipe fitting for positioning by a thimble 3.
The supporting section 202 of the inner chuck is obtained by turning, the inner chuck is clamped by using a heightened long clamping jaw matched with a lathe, the three inner chucks 2 are closed, and the arc shaft of the supporting section 202 is turned, so that the arc shaft forms a cylinder with an inner hole smaller than that of the pipe fitting when being closed; after the inner clamping head 2 is machined, a lathe is mounted, the inner clamping head 2 is closed, the supporting section 202 penetrates into an inner hole of the pipe fitting, the inner clamping head 2 is opened, the supporting section 202 is opened to be tightly attached to the inner hole wall of the pipe fitting 1 to support a fixed part, the thimble 3 is arranged at the other end of the pipe fitting 1, if the full length needs to be cut, the inner clamping head is closed, the pipe fitting 1 is loosened and pulled to the rear end to be positioned, and finally, the outer circle is turned and the full length is.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
