Description
Technical Field
[0001] The utility model relates to the technical field of machine tool accessory equipment, in particular to a new type of rotary hexagonal punch holder. Background Technique
[0002] The automatic lathe core-pulling machine belongs to precision lathe processing equipment, which can quickly and automatically cut and extrude various products with internal hexagonal structures, and is widely used in the batch processing of precision hardware and special-shaped non-standard parts of shafts.
[0003] During the process of using the automatic lathe core-pulling machine to process parts, the punch holder, as a key component, has an important impact on the machining accuracy and efficiency of the machine tool. When the traditional punch holder is used for a long time, the punch is prone to looseness or vibration, and the stability is insufficient, affecting the machining accuracy of the parts; moreover, some existing punch holders have insufficient wear resistance and poor durability, affecting the service life. Therefore, in view of the existing problems, we urgently need an improved punch holder to improve its stability, durability and convenience of use. Content of the Utility Model
[0004] In view of the above situation, to overcome the current technical defects, the utility model provides a new type of rotary hexagonal punch holder that is easy to use. Through this punch holder, the stability during processing can be improved, the influence of punch shaking on processing can be prevented, and the machining accuracy of parts can be guaranteed.
[0005] The technical solution adopted by the utility model is as follows: The new type of rotary hexagonal punch holder provided by this solution includes a back shaft main body installed on a CNC lathe core-pulling machine. A bearing sleeve is threadedly connected to the front end of the back shaft main body. A punch sleeve is detachably installed in the bearing sleeve. A bearing one and a bearing two are respectively arranged at the front and rear parts of the connection between the punch sleeve and the bearing sleeve. The bearing one can play a role in limiting and supporting the punch sleeve, so that the friction coefficient during the movement of the punch sleeve can be reduced when it rotates, and its rotational accuracy can be guaranteed; the bearing two arranged can play a role in strengthening the support of the punch sleeve, reducing the swing and friction coefficient during the movement of the punch sleeve, and guaranteeing the rotational accuracy of the punch sleeve.
[0006] Further, a punch for cutting and processing parts is installed at the front end of the punch sleeve, and the punch and the punch sleeve are installed, fixed and limited through a fixing screw one.
[0007] Further, the connection between the rear end of the punch sleeve and the bearing sleeve is installed and fixed through a screw two. The punch sleeve and the bearing sleeve can be stably installed and fixed through the screw two, ensuring that the punch and the punch sleeve will not move up, down, left or right in the bearing sleeve, and improving the stability of the punch during use.
[0008] In order to facilitate the installation and disassembly of the punch holder, screw through holes for installation and fixation with a CNC lathe are provided on the back shaft body.
[0009] The beneficial effects achieved by the present utility model with the above structure are as follows:
[0010] 1. The first bearing provided can play a role in limiting and supporting the punch sleeve, enabling the punch sleeve to reduce the friction coefficient during its movement when rotating and ensuring its rotational accuracy.
[0011] 2. The second bearing provided can play a role in strengthening the support of the punch sleeve, reducing the swing and friction coefficient during the movement of the punch sleeve, and ensuring the rotational accuracy of the punch sleeve.
[0012] 3. The first fixing screw can facilitate the installation, fixation and replacement of the punch.
[0013] 4. The second screw can firmly install and fix the punch sleeve and the bearing sleeve, ensuring that the punch and the punch sleeve will not move up, down, left or right within the bearing sleeve, and improving the stability of the punch during use.
[0014] 5. Through the screw through holes provided on the back shaft body for installation and fixation with a CNC lathe, the installation and disassembly of the punch holder can be facilitated. Description of the Drawings
