Technical Field

The invention relates to the technical field of metalworking practice, in particular to a method for preventing a lathe from colliding with a cutter and the lathe.

Background

At present, metalworkers in colleges and universities have common lathe training courses, and students who practice all contact the lathe for the first time and have no knowledge about the common lathe training courses. However, people are very interested in touching real operation classes for the first time after going through theoretical classes for a long time, and are in the first place to start up to operate. But if the machine tool is improperly operated, physical injury can be directly brought to students. Therefore, teachers can particularly emphasize standard operation and carefully practice operation when explaining the operation steps of the machine tool.

However, in the actual gold worker practice process, a lathe hurting event still occurs occasionally because the conventional common lathe has no safety protection device, if a practice student mistakenly operates the automatic moving knife rest, or because of nervousness, when the moving knife rest is started, the moving knife rest is obviously seen to be very close to the high-speed chuck, and how to stop the feeding of the moving knife rest in the Z direction is taken, the moving knife rest collides with the chuck at a high speed, so that the machine is damaged, even the student is injured, a serious accident occurs, a light person causes the damage of a cutter, and a serious person causes personal injury because the collided knife rest is rebounded to the student.

Disclosure of Invention

The invention aims to solve the technical problems that in order to avoid repeated occurrence of safety accidents and rehearsal of tragedies in metalworker practice courses, students can safely and boldly operate a lathe, and a method for preventing the lathe from colliding with a cutter and the lathe are designed.

The technical scheme adopted by the invention for solving the technical problems is as follows: a method of preventing a lathe from crashing into a knife, comprising the steps of: a lock ring and a belt groove are arranged at the rear end of the moving tool rest, and a locking mechanism is arranged at the rear end of the rack; a belt is arranged in the belt groove, one end of the belt is tied to the lock ring, and the other end of the belt is tied to the locking mechanism; a boring cutter is arranged on the moving cutter frame; when the moving tool rest moves normally, the belt and the locking mechanism move normally; when the movable tool rest moves forwards reversely, the locking mechanism is locked instantly, the belt prevents the movable tool rest from moving forwards continuously, and the movable tool rest stops moving forwards.

A lathe, comprising: a frame; the moving tool rest is arranged on the rack in a sliding manner; the boring cutter is arranged on the moving cutter frame; the belt groove is arranged at the rear end of the moving knife rest; a lock ring disposed at a rear end of the moving blade holder, the lock ring disposed within the belt groove; the locking mechanism is arranged at the rear end of the rack; and one end of the belt is tied to the lock ring, and the other end of the belt is tied to the locking mechanism.

Furthermore, a rubber pull belt is arranged in the middle of the belt.

Furthermore, the lock ring is connected with the movable tool rest by an adjusting rod.

Further, a centrifugal clutch is arranged in the locking mechanism.

The invention has the beneficial effects that:

1. the injury to personal safety caused by the fact that students are nervous or unskilled and improper in operation can be effectively avoided, the safety of the lathe is greatly improved, the sense of insecurity in mind caused by the fact that the students practice operating the lathe by the college metalworkers is solved, and the practice level of the students is improved;

2. the safety protection device is designed, the safety is ensured by judging the movement of the moving tool rest, the collision between the tool rest and the chuck is avoided, the safety of the lathe is improved, and the risk of tool collision of the lathe caused by misoperation and tension of a metalworker practice student is solved.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments is as follows:

a method for preventing a lathe from colliding with a cutter, as shown in fig. 1, comprising the steps of:

the rear end of the moving tool rest 2 is provided with a lock ring 5 and a belt groove 4, the rear end of the rack 1 is provided with a locking mechanism 6, the belt groove 4 is internally provided with a belt 7, one end of the belt 7 is tied on the lock ring 5, and the other end of the belt 7 is tied on the locking mechanism 6.

A boring cutter 3 is mounted on the moving cutter holder 2.

When the moving tool rest 2 moves normally, the belt 7 and the locking mechanism 6 move normally; when the movable tool rest 2 moves forwards reversely, the locking mechanism 6 is locked instantly, the belt 7 prevents the movable tool rest 2 from moving forwards continuously, and the movable tool rest 2 stops moving forwards.

The invention also provides a lathe comprising the method, which is a specific application of the method and can realize the same beneficial effects as the method.

A lathe, as shown in figure 1, comprises a frame 1, a movable tool rest 2, a boring tool 3, a belt groove 4, a lock ring 5, a locking mechanism 6 and a belt 7.

The moving tool rest 2 is arranged on the frame 1 in a sliding mode, the boring tool 3 is arranged on the moving tool rest 2, the belt groove 4 is formed in the rear end of the moving tool rest 2, the lock ring 5 is arranged at the rear end of the moving tool rest 2, the lock ring 5 is arranged in the belt groove 4, the locking mechanism 6 is arranged at the rear end of the frame 1, one end of the belt 7 is tied on the lock ring 5, and the other end of the belt is tied on the locking mechanism 6.

When the moving tool rest 2 moves, the belt 7 moves along with the moving tool rest and is straightened. When the belt 7 moves forwards reversely, namely, the belt exceeds the safe movement distance, or the movement speed exceeds the normal speed, the locking mechanism 6 can fix the belt 7 instantly, which is similar to the principle of an automobile safety belt, so that the movable knife rest 2 is protected, and the safety is improved. The locking mechanism 6 may employ a centrifugal clutch.

Preferably, the middle part of the belt 7 is provided with a rubber pull belt for playing a role of buffering. The locking ring 5 is connected with the moving tool rest 2 by adopting an adjusting rod 8 to adjust the safety distance of the belt 7.

The invention has been described above with reference to a preferred embodiment, but the scope of protection of the invention is not limited thereto, and various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the invention, and features mentioned in the various embodiments can be combined in any way as long as there is no structural conflict, and any reference sign in the claims should not be construed as limiting the claim concerned, from which the embodiment is to be regarded as being exemplary and non-limiting in any way. Therefore, all technical solutions that fall within the scope of the claims are within the scope of the present invention.
