Description

Technical Field

[0001] The utility model relates to the technical field of lathe manufacturing, in particular to an automatic centering device for machining special-shaped workpieces on a lathe. Background Technique

[0002] A lathe is regarded as the "mother machine" of all equipment in industry. It can process many types of workpieces and is an essential production tool in many manufacturing processing industries. A lathe mainly uses a turning tool to perform turning processing on a rotating workpiece. For a regular-shaped circular revolving body, a three-jaw chuck is generally used for clamping. With the development of modern industry and the popularization of automated processing lines, the types of workpieces are becoming more and more diverse. In order to adapt to the automated production line and handle more variable workpieces, there are more challenges for lathes. Therefore, a lathe suitable for special-shaped workpieces and capable of automatically clamping workpieces conforms to the development trend of modern manufacturing and will bring a huge improvement in efficiency to modern manufacturing. Therefore, technical personnel in this field have provided an automatic centering device for machining special-shaped workpieces on a lathe to solve the problems raised in the above background technique.

An irregular L-shaped workpiece is placed at a limited position in the middle of the centering device group.

[0004] The centering device group includes a workpiece base, a placement groove, a fixing notch, an insertion slot, a threaded live hole, an avoidance groove, a limit bolt, a fixing rotating rod, a positioning rotating rod, a receiving groove, and a threaded slot hole. A placement groove is opened in the middle of the front end face of the workpiece base. An insertion slot is opened on the left side of the bottom of the placement groove. The insertion slot and the placement groove form a notch to facilitate the accommodation of the irregular L-shaped workpiece. Fixing notches are opened in the upper part of the front end face of the workpiece base. Two left and right threaded live holes are opened on the wall groove surface of the fixing notch. A fixing rotating rod is arranged in the left threaded live hole. By rotating the fixing rotating rod into the placement groove, the irregular L-shaped workpiece placed in the placement groove is limited and fixed, thus ensuring stable processing. A threaded slot hole is opened on the left side of the workpiece base. A positioning rotating rod is arranged in the threaded slot hole. The positioning rotating rod passes through the threaded slot hole to limit and fix the irregular L-shaped workpiece, thus preventing the irregular L-shaped workpiece from shifting during the processing.

[0005] Preferably: A receiving groove is opened in the middle of the bottom of the placement groove. The receiving groove is used to accommodate the lathe machining head after the machining of the irregular L-shaped workpiece is completed.

[0006] Preferably, a limit bolt is arranged in the threaded live hole on the right side. The limit bolt inside the threaded live hole is pre-rotated, and the limit bolt is inserted into the placement groove, so that the position of the special-shaped L workpiece in the placement groove is adjusted relative to the lathe machining position, ensuring the centering machining of the special-shaped L workpiece.

[0007] Preferably, an avoidance groove is opened on the front groove surface of the fixed notch. The limit bolt and the fixed rotating rod are correspondingly arranged with the avoidance groove, so as to ensure the normal movement of the limit bolt and the fixed rotating rod to restrict the special-shaped L workpiece and prevent movement blockage.

[0008] Preferably, the assembly component includes a collar, a connecting end post and a bolt groove. The collar is fixedly installed at the rear end of the workpiece base, and the connecting end post is fixedly installed at the rear end of the collar.

[0009] Preferably, a bolt groove is annularly arranged on the side end face of the connecting end post, and a fixing bolt is arranged in the bolt groove. The connecting end post is fixedly installed on the machine tool through the cooperation of the fixing bolt and the bolt groove, so as to facilitate the processing and fixing of the special-shaped L workpiece.

[0010] The technical effects and advantages of the present utility model:

[0011] When the present utility model is used, the connecting end post is fixedly installed on the machine tool through the cooperation of the fixing bolt and the bolt groove. The limit bolt inside the threaded live hole is pre-rotated, and the limit bolt is inserted into the placement groove, so that the position of the special-shaped L workpiece in the placement groove is adjusted relative to the lathe machining position, ensuring the centering machining of the special-shaped L workpiece. The special-shaped L workpiece is inserted into the notch formed by the insertion slot and the placement groove. By rotating the fixed rotating rod and inserting it into the placement groove, the special-shaped L workpiece placed in the placement groove is limited and fixed, so as to ensure stable processing. Then, the positioning rotating rod is rotated to pass through the threaded groove hole to limit and fix the special-shaped L workpiece, so as to prevent the special-shaped L workpiece from shifting during the processing, control the pressing and loosening of the special-shaped L workpiece, and cooperate with the manipulator to meet the requirements of the production line.
