Description

Protection device for cutting tools

Technical field

The technical solution relates to a safety device for cutting tools, in which the protection of the cutting tool in case of its jamming or wrong approach to the working position is solved.

BACKGROUND OF THE INVENTION

So far, cutting tools, such as taps and threaded eyes, are fixed in machine tools and automatic machines. That is, through a cone or cylindrical surface. When the tool is moved to the working position or during the working operation, the tool may get stuck and result in failure of both the tool and the machined part.

The essence of the technical solution

These drawbacks are largely eliminated by a safety device for cutting tools consisting of a body, a cam and springs, which is based on the fact that the base body, with an internal abutment and an external clamping surface, is slidably and rotatably supported over the second spring on the internal abutment a clamping body with a clamping space into which a cutting tool or a first holder or a second holder is inserted. At the same time, the clamping body is fastened in the axle by a release clip. The other end of the release tab is seated over the first spring on the internal support shoulder. A pawl is seated in the central part of the clamping body via a release spring. A cam pawl is mounted against the pawl in the base body on the pivot pin. On the first holder, an outer gripping shoulder with formed punches and threaded holes is provided on both sides, a through hole is formed in the central part and internal clamping holes are formed on both sides. On the other holder, on the one hand, an outer retaining shoulder with pits is formed, on the other hand, an internal clamping bore with threaded holes is formed, and a through hole is provided in the central part.

Said belay device allows a slight cushioning upon engagement and locking of the cutting tool by sliding the latch system. Furthermore, it allows forwards when cutting the thread to the head of the screw, the reverse is hard.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The technical solution is explained in more detail by means of the drawings, in which FIG. 1 shows a cross-section of a belaying device for cutting tools, FIGS. 2, 3 show a first holder and FIGS.

Exemplary embodiment

The locking device for the cutting tools consists of a base body 2 and a clamping body 1. In the base body 2, with an internal abutment 12 and an outer clamping surface 3, a clamping body I with a clamping body 1 is slidably and rotatably supported over the second spring 5. At the same time, the clamping body 1 is fastened in the O-axis by the release tab 6. The second end of the release tab 6 is seated via the first spring 4 on the inner support shoulder 12. In the middle part of the clamping body 1, through the release spring 11 with the adjusting screw 10, a pawl 9 is seated against which a cam pawl 7 is mounted in the base body 2 on the pivot pin 8. On the first holder 14 an outer gripping shoulder 15 is formed on both sides. threaded holes 20, with a through hole formed in the central portion 16, and internal clamping holes 18 are formed from both sides. On the other holder 17 an outer gripping shoulder 15 is formed from one side

On the other hand, an internal clamping bore 18 is provided with threaded holes 20, and a through bore 16 is provided in the central portion.

For example, a threaded eyelet or tap or a first holder 14 or a second holder 17 is firmly incorporated into the clamping space 13. When the working operation is started, the clamping body 1 can spring by means of a second spring 5. In the event of blocking the cutting tool.

Industrial applicability

The safety device for cutting tools can be used in machine tools, lathes, machining centers and automatic machines.
