Technical Field

The invention belongs to the technical field of numerically controlled lathes, and particularly relates to an automatic discharging device.

Background

The automation of numerical control equipment has become a major trend of future processing, the full-automatic processing of the current numerical control lathe is also about to become a major trend of the future, the realization of the self-defined feeding and discharging of workpieces is the premise of realizing full automation, so that the increasing product ordering requirements are met, automatic discharging during workpiece processing cannot be realized by a chuck used on the current numerical control lathe, and chips are accumulated in the chuck, so that the workpiece has poor dimensional stability, long processing time and low speed.

Disclosure of Invention

The invention aims to overcome the defects and provide the automatic discharging device which can push out the accumulated chips in the chuck together, reduce the difficulty in cleaning the accumulated chips after the workpiece is machined, keep the interior of the chuck clean, play a good role in improving the quality and the dimensional stability of the machined workpiece, and have short machining time and high speed.

The purpose and the main technical problem to be solved of the invention are realized by adopting the following technical scheme:

the invention relates to an automatic discharging device, which is characterized in that; the middle part is installed with the spring in the shell, and the ejector pin of unloading is installed to one end in the shell, and adjusting bolt is twisted into to the other end, and spring both ends head contacts with an end of ejector pin, a bolt end respectively of unloading.

The two ends of the discharging ejector rod are large, and the middle part of the discharging ejector rod is small.

The discharging ejector rod can move left and right in the shell.

One end of the shell is small, the other end of the shell is large, and threads are arranged outside the other end of the shell.

Compared with the prior art, the invention has obvious beneficial effects; the technical scheme shows that: a spring is arranged in the middle of the shell, an unloading ejector rod is arranged at one end of the shell, an adjusting bolt is screwed into the other end of the shell, and two end heads of the spring are respectively contacted with one end head of the unloading ejector rod and one end head of the bolt. The thread arranged outside the other end of the shell is screwed into the thread in the chuck, when the chuck is in a loosening state, the left end of the discharging ejector rod 1 is flush with the left end surface of the chuck under the pushing action of the spring in the shell, when the chuck is in a loosening state, the workpiece is inserted into the center of the chuck, the workpiece pushes the discharging ejector rod, the discharging ejector rod moves towards the inside of the shell, the discharging ejector rod pushes the spring to apply pressure, the spring is compressed, when the workpiece extends into a proper position in the chuck, the chuck is used for clamping the workpiece, after the workpiece is machined, the chuck is loosened, the discharging ejector rod pushes the workpiece out of the chuck through the elasticity of the spring, accumulated scraps in the chuck are pushed out together while the workpiece is pushed out, the difficulty in cleaning the accumulated scraps after the workpiece is reduced, the inside of the chuck is kept clean, and the quality and the dimensional stability of the machined workpiece are improved, the processing time is short and the speed is high.

Detailed Description

The details of the embodiments, structures, features and functions according to the present invention are described in the following detailed description and the preferred embodiments.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention relates to an automatic discharging device, which is characterized in that; the middle part installs spring 4 in the shell 2, and ejector pin 1 of unloading is installed to one end in the shell 2, and adjusting bolt 3 is twisted to the other end, and 4 both ends of spring contact with 1 end of ejector pin, 3 one end of bolt of unloading respectively.

The two ends of the discharging ejector rod 1 are large, and the middle part of the discharging ejector rod is small.

The discharging ejector rod 1 can move left and right in the shell 2.

One end of the shell 2 is small, the other end of the shell is large, and threads are arranged outside the other end of the shell.

When in use, the chuck 5 is in a loosened state, the left end of the discharging ejector rod 1 is kept flush with the left end surface of the chuck under the pushing action of the spring in the shell 2, when in feeding, by inserting a workpiece into the center of the chuck 5, the workpiece pushes the discharging ejector rod 1, the discharging ejector rod 1 moves towards the inside of the shell 2, the discharging ejector rod pushes the spring 4 to apply pressure, the spring 4 is compressed, the workpiece extends into a proper position in the chuck 5, the chuck 5 is used for clamping the workpiece, after the machining is finished, the chuck 5 is loosened, the spring 4 pushes the discharging ejector rod 1, the unloading ejector rod 1 is pushed by the elasticity of the spring 4 to push the workpiece out of the chuck 5, the accumulated chips in the chuck 5 are pushed out together when the workpiece is pushed out, when the elasticity of the spring 4 pushes the discharging ejector rod 1 to push the workpiece out of the chuck 5, the bolt 3 is adjusted, the bolt 3 is screwed into the shell 2 to push the spring 4 to compress, and the elasticity of the spring 4 is increased.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
