Description

Guided collet

The invention relates to a guiding collet, in particular to a cutter collet structure which can assist in concentrating the cutting fluid to the tool processing and avoiding the deviation of the tool from the axis.

With the advancement of industrial processing technology, the application of automated multi-function processing tools (such as CNC lathes) to process objects such as cutting, drilling, etc., to replace the traditional processing of manpower control tools is becoming more and more popular. The processing type, and the various types of tools and various sizes of tools can be selectively switched to the characteristics of automatic multi-function processing tools in response to various processing operations.

In the case of the conventional automatic processing machine, in a tool holding device having a cutting fluid from the inside, the tool is often fixed by a clamping collet and a locking cap when clamping the tool, and the clamping is performed. The collet itself is an additional sleeve, so it is easy to have a problem of being fixed off the axis. As a result, the cutter itself is eccentric and affects the machining, and the cutting fluid discharged from the inside is converged from the center. Therefore, it is also possible to lose through the gap of the clamping collet, so that the cutting fluid is not easily concentrated to be sprayed into the processing place where the chipping is accumulated, so that the obtained chip removing effect is compromised, which leads to the necessity of using more The external jet cutting fluid is used for chip removal, which has its deficiencies in application. Therefore, the inventors of the present invention have thought about and designed a guiding collet with water sealing function in view of the prior art. The lack of it is improved to enhance the implementation and utilization of the industry.

In view of the above-mentioned shortcomings of the prior art, the present invention designs a guiding collet having a sealing function with novelty, advancement and industrial utilization, etc., in order to overcome the difficulties of the prior art.

In order to achieve the above object, the technical means adopted by the present invention is to design a guiding collet, comprising: a collet body having a set of holes in the center to be correspondingly sleeved on a cutter, and the collet The body is provided with at least one adjusting opening on the outer wall surface of the sleeve hole, so that the collet body has elasticity; and an extending section correspondingly disposed on one end of the collet body is a ring shape Straight sleeve structure.

Wherein, the adjustment opening is distributed on the body of the collet.

Wherein, one end of the collet system is a rear end, and the other end is a front end.

Wherein the extension is disposed at the rear end of the collet body.

Wherein, in one of the extensions, the inner wall surface of the ring is further provided with a waterproof sealing ring groove.

The guiding collet with water sealing function of the invention is designed to provide a steerable assembly tool, which is accurately aligned with the axis of the tool holder, and at the same time provides an insulating cutting fluid to prevent leakage The problem is that it has excellent application convenience and excellent application convenience.

In order to make the above-mentioned objects, technical features, and gains after actual implementation more obvious, a more detailed description will be given below with reference to the corresponding drawings in the preferred embodiments.

The present invention will be described in conjunction with the accompanying drawings in the accompanying drawings, and the drawings The subject matter is only for the purpose of illustration and description.

Those terms defined by the dictionary should be understood to have the meaning consistent with the relevant fields, and unless explicitly defined in the following text, they will not be understood in terms of excessive idealization or excessive formality.

Referring to Figures 1 to 3, the present invention provides a guiding collet having a water sealing function, which is assembled in a tool holder (90) to fix a cutter (80) and pass through a The lock cap (70) is forced, and in a preferred embodiment, a collet body (10) and an extension (20) can be included.

The collet body (10) has a set of holes (11) in the center to be correspondingly sleeved on the cutter (80), and the collet body (10) is outside the ring wall of the sleeve hole (11). The upper system is provided with at least one adjusting opening (12), which may be disposed on the collet body (10) in a long shape, so that the collet body (10) has elasticity and is sleeved on the locking cap (70). When the outside of the collet body (10) is pressed or loosened, the collet body (10) can be clamped and loosened to the cutter (80), and the collet body (10) is further One end is the rear end (13) and the other end is the front end (14) to conform to the inclined wall surface of one of the opening of the lock cap (70).

The extension (20) is correspondingly disposed on one end of the collet body (10), or may be disposed at the rear end (13), which is an annular straight sleeve structure, and can be correspondingly matched. Directing one of the openings of the tool holder (90) to guide the straight groove (91), thereby generating a guiding function to avoid deviation from the axis during assembly and outside the extension (20) A first waterproof sealing ring (60) may be further disposed between the ring wall surface and the guiding straight groove (91), and the first waterproof sealing ring (60) is compressed to achieve a waterproof function.

And a waterproof sealing ring groove (21) is further disposed on the inner wall surface of the extending portion (20), and further disposed on the waterproof sealing ring groove (21) when being disposed on the cutter (80) The second waterproof sealing ring (61) functions as a closed waterproof.

Please further refer to FIG. 4, wherein in a modified embodiment, the front end (14) of the collet body (10) may correspond to one of the tool holders (90A) opening, and the extension The segment (20) corresponds to a guide straight hole (71A) opening in one of the lock caps (70A), and is further provided with a first waterproof seal ring (60) to produce a waterproof function equivalent to the above; the second waterproof seal ring (61) is disposed between the extension (20) and the cutter (80) and is compressed to produce a waterproof effect. Wherein, the lock cap (70A) can be used without adding a disc to the collet body (10), and is matched with the extension (20) to clamp the tool holder. At the same time, there is no problem of leakage of the cutting fluid, and at the same time, the time for tool replacement can be saved.

Through the ingenious change of the design of the guide collet with water sealing function of the present invention, it provides a steerable assembly tool (80) which is accurately aligned with the tool holder (90) (90A) The axis of the shaft, and at the same time provides the problem of isolating the cutting fluid to prevent it from leaking out, has excellent application convenience, and is inaccessible to the conventional technology, so the gain is visible.
