Abstract
The utility model relates to a threaded mandrel force unloading device which comprises a machine tool chuck, a processed part and a threaded mandrel. The threaded mandrel is arranged into the machine tool chuck; a cap with a force adding hole is screwed on an external thread of the threaded mandrel; the processed part is screwed on the outer thread of the cap, and is positioned on the excircle and the step of the threaded mandrel; and the cap axially tightens the processed part. The threaded mandrel force unloading device has the beneficial effects of simple structure, convenient loading and unloading, higher shift output and the like.
Description
Technical field
The utility model relates to a kind of threaded mandrel and unloads power apparatus.
Background technology
In the Vehicle Processing of our factory, often use the anchor clamps form of threaded mandrel, part directly screws on the threaded mandrel by inner hole thread, because the effect of rotating inertia force, carrying out along with processing, part screw thread and mandrel thread are more and more tightr, particularly on numerically controlled lathe, process now, thick finishing step is concentrated, chipping allowance is big, and cutting moment also increases thereupon, impels the operator to be difficult to part is spun down from anchor clamps after car is finished the part cylindrical, labor strength is big, darg gets off exhausted, and the screw thread of part and threaded mandrel also is easy to damage, and seriously restricts the lifting of production efficiency and production capacity, increase manufacturing cost, needed double thread mandrel structure to improve for this reason.
Summary of the invention
The purpose of this utility model provides a kind of threaded mandrel simple in structure, that the machine tooling of conveniently assemble and disassemble is used and unloads power apparatus.
The utility model solves by following technical proposal: comprise machine chuck, processing parts, threaded mandrel.The threaded mandrel machine chuck of packing into, establish one with afterburning hole and cap be spun on the external screw thread of threaded mandrel, processing parts is spun on and the cap external screw thread on, processing parts is located on the cylindrical of threaded mandrel and step, and cap is axially strained processing parts.
Description of drawings
Fig. 1 is the utility model embodiment overall structure schematic diagram.
Fig. 2 is the utility model embodiment and cap schematic diagram.
The specific embodiment
As shown in the figure, threaded mandrel 2 is packed on the machine chuck 1, with and cap 3 be spun on the external screw thread of threaded mandrel 2, again part 4 is spun on and cap 3 external screw threads on, part 4 is located on the cylindrical of threaded mandrel 2 and step, and cap 3 is strained part axial, also on the cap 3 afterburning hole 5 is being set, after the part machining is finished, utilize afterburning rod and cap 3 unscrew, part 4 also just be easy to from and cap 3 spin down, here and cap 3 very crucial, the internal and external threads concentricity requirement is higher, take clamping No. one time when processing and cap 3, internal and external threads cuts out simultaneously, or after also cap 3 screws on positioning threads plug 2, the external screw thread ensuring method that direct car goes out on the lathe of processing parts 3 is to guarantee the mutual alignment requirement between the internal and external threads and the location shaft shoulder.
This improvement had solved in the past and had directly clamped the difficult problem that screws off with the threaded mandrel location, was innovation on the method for thinking to the processing of this type of part, had alleviated operator's labour intensity, improved class and produced more than 3 times, and similar part is had general promotional value.
In sum, the utlity model has simple in structure, conveniently assemble and disassemble, raising class and actively effect such as produce.
Claims (1)
1. a threaded mandrel is unloaded power apparatus, comprise machine chuck, processing parts, threaded mandrel, it is characterized in that: the threaded mandrel machine chuck of packing into, if an also cap with afterburning hole is spun on the external screw thread of threaded mandrel, with processing parts be spun on and the cap external screw thread on, processing parts is located on the cylindrical of threaded mandrel and step, and cap is axially strained processing parts.
