Description
Technical Field
The utility model belongs to the technical field of the machining center technique and specifically relates to an used split type output shaft of toolchanger.
Background
The tool magazine equipped in the numerical control machining center is provided with ATC tool changing devices, when a tool is changed, power is transmitted by the square shaft through the rotation of the rotating tower shaft to drive the output shaft to rotate, and finally the output shaft drives the tool arm to rotate so as to realize tool changing. Wherein the output shaft is connected with the square shaft through the square hole, and current output shaft structure is generally the monolithic structure, and the whole output shaft is run through to the square hole axial, and the technological requirement is higher, and the machining precision is wayward, and the cost of manufacture is also high.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a split type output shaft which is convenient for control the processing precision and reduce the technological requirements.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a split type output shaft for drive the tool arm and rotate and realize the tool changing on the tool magazine tool changer, have output shaft core, output shaft sleeve, the hole front end of output shaft sleeve be the screw hole, output shaft core have with tool changer's square shaft sliding fit's square hole, output shaft core periphery and the screw hole threaded connection of output shaft sleeve.
In order to prevent the threaded connection from loosening, an axial pin is arranged at the joint between the output shaft core and the output shaft sleeve.
The utility model has the advantages that: the utility model discloses with the output shaft split for the output shaft core with the output shaft cover and adopt threaded connection, the preparation is convenient, can reduce the processing requirement, ensures machining precision, reduce cost.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the structure comprises a force shaft core, 2 force shaft sleeves, 3 square shafts, 4 square holes and 5 axial pins.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The split type output shaft shown in fig. 1 is used for driving a tool arm to rotate on a tool magazine tool changer to realize tool changing, and is provided with an output shaft core 1 and an output shaft sleeve 2, wherein the output shaft sleeve 2 is provided with a step inner hole, the front end part of a large hole of the step inner hole is a threaded hole, the rear end part of the large hole of the step inner hole is a round hole, and a step surface is formed between the round hole and the end part of the small hole.
The front end part of the periphery of the output shaft core 1 is provided with an external thread matched with a threaded hole of the output shaft sleeve 2, the rear end part of the periphery of the output shaft core 1 is an optical axis matched with a round hole, when the output shaft core 1 is in threaded connection with the output shaft sleeve 2, the optical axis is matched and positioned with the round hole, and the inner end of the optical axis is attached to the step surface of a step inner hole, so that the matching concentricity of the output shaft core 1 and the output shaft sleeve 2 is ensured.
And an axial pin 5 is screwed in the threaded connection part between the output shaft core 1 and the output shaft sleeve 2 in a straddling way to prevent the threaded connection between the output shaft core 1 and the output shaft sleeve 2 from loosening.
The output shaft core 1 is provided with a square hole 4 which is in sliding fit with a square shaft 3 of the tool changing device, so that the output shaft can slide left and right on the square shaft.
The utility model discloses with the output shaft split for output shaft core 1 and output shaft sleeve 2 and adopt threaded connection, the preparation is convenient, can reduce the processing requirement, ensures machining precision, reduce cost.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
