Description

Follow the tool rest structure

This creation belongs to the technical field of a lathe processing, specifically referring to a CNC lathe's follower structure, which can avoid deflection during the turning process and improve the machining accuracy.

According to the existing lathe machining process, the slenderness ratio of the workpiece is restricted during turning. When the ratio of the diameter to the length of the workpiece is too small, the rigidity of the workpiece will be insufficient, and the pressure of the turning tool will cause the workpiece to be cut. In the turning process, force deflection will occur, resulting in poor machining surface, roundness and concentricity will also be affected, which will affect the accuracy of machining dimensions, and even form defective products. In order to solve the aforementioned problems, the lathe industry has developed two accessories, the center frame and the follower, which are used in the processing environment of relatively small workpieces;

Generally, the follower tool holder can move in the same direction with the tool holder body. Under normal circumstances, it is forward turning, which is most effective for turning slender shafts, while the center frame is fixed in position. Generally, position adjustment is not performed in a process, but only for strengthening. The workpiece is rigidly supported, but the existing accessory tool holder has some problems. For example, its contact and separation with the workpiece is accomplished by rotating the two supporting claws on the tool holder to advance and retreat, and During the machining process, fixing bolts are required to tighten the supporting claws, which is extremely inconvenient in operation, resulting in great limitations on functions and effects.

In other words, since the existing follower tool holder simply moves in the same direction with the tool holder body, it is not easy to adjust when the bearing claw of the follower tool holder is far away from the workpiece, and it supports the axis of different workpieces in the same batch of workpieces. The accuracy is poor. At the same time, when the machining is completed, the tool holder needs to be manually withdrawn, which affects the overall machining efficiency. How to solve the aforementioned problems is what the industry expects and is also a technical problem that this creation intends to solve.

In view of this, the author has made in-depth discussions on the problems faced by the existing follower tool holders. Based on the needs of technological development in recent years, through continuous efforts to improve and trial, finally successfully developed a follower tool holder structure to overcome The trouble caused by the inconvenient operation before and after the existing processing.

Therefore, the main purpose of this creation is to provide a tool holder structure that can be controlled by a servo motor to facilitate the contact and exit of the processing of the same size after the adjustment is completed. There is no need to repeatedly adjust the contact, and it can automatically exit. Can improve the overall processing efficiency.

Furthermore, another main purpose of this creation is to provide a tool holder structure that can maintain the supporting accuracy of the same batch of workpieces, thereby improving the processing accuracy and yield of the same batch of workpieces.

Based on this, this creation is mainly through the following technical means to specifically achieve the aforementioned objectives and effects: the lathe is equipped with a body on a machine table, and the body has a movable tool module, wherein the tool mold The assembly is provided with a saddle that can be linearly displaced on the fuselage, and one end of the saddle is provided with a tool holder for selectively installing tools, so that the tool holder can drive the tool to move vertically relative to the axis of a workpiece. Its characteristics are:

The saddle of the tool module is different from the tool holder and the other end is provided with a corresponding knife module. The knife module has a base, wherein the base is locked to the aforementioned mounting base, and on the base It has a guide rail extending perpendicular to the axis of the workpiece, and a mounting seat is slidably provided on the base guide rail, and a drive unit is arranged between the base and the mounting seat, and the drive unit can servo actuate the mounting seat on the base for selection It is close to or far away from the workpiece, and the mounting seat is provided with a follower holder, and the follower holder has at least two supporting claws corresponding to the periphery of the workpiece.

In this way, through the specific realization of the above technical means, the follower tool holder structure of this creation can be fixed on the side of the tool module saddle by using the base of the follower module, so that the mounting seat on the base can use the drive unit Actuate, so that the mounting seat can drive the follower tool holder to approach the workpiece, so that after the completion of the axis support adjustment, it can automatically approach and support the same batch of workpieces and automatically return. There is no need to set one by one like the existing one, which can greatly improve work efficiency. At the same time, it can also maintain the axis support accuracy of the same batch of workpieces, thereby improving the processing accuracy and yield of the same batch of workpieces, so as to increase its added value and further improve its economic benefits.
