Detailed Description
To further illustrate the technical means and effects of the present invention for achieving the predetermined purpose, the following detailed description of a high-precision clamping tool holder according to the present invention, its specific implementation, structure, features and effects will be given below with reference to the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
It will be understood that when an element is referred to as being "disposed" or "connected" to another element, it can be directly on the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The specific scheme of the high-precision clamping tool holder provided by the invention is specifically described below with reference to the accompanying drawings.
Referring to fig. 1 to 5, in order to solve the technical problem of low positioning accuracy of the fit between the inner hole of the cutter and the positioning cylinder of the cutter handle, the embodiment of the invention provides a high-accuracy clamping cutter handle, and the cutter handle converts the fit relationship between the surfaces into the fit relationship between the points and the surfaces, so that the positioning accuracy is effectively improved. Specifically, the high-precision clamping knife handle comprises a knife handle body 1, a positioning cylinder 3, a retaining sleeve 2 and a blocking piece. In this embodiment, the snap spring 6 is used as a blocking member, the positioning cylinder 3 is provided with a snap groove 31, and the snap spring 6 is installed in the snap groove 31 to achieve the blocking function.
Specifically, the positioning cylinder 3 is arranged on the tool holder body 1 and used for clamping a tool. The retaining sleeve 2 is coaxially sleeved on the outer side of the positioning cylinder 3. A plurality of balls 21 are fitted in the circumferential direction of the retaining sleeve 2, and the diameter of the balls 21 is larger than the thickness of the retaining sleeve 2. When the cutter is sleeved on the positioning cylinder 3, the cutter radially extrudes the ball 21 to enable the ball 21 to compress the positioning cylinder 3, and then the cutter is tightly matched with the positioning cylinder 3 through the retaining sleeve 2. In order to prevent the axial movement of the retaining sleeve 2, a locking groove 31 is provided circumferentially at the end of the positioning cylinder 3, a locking spring 6 is mounted in the locking groove 31, and the axial movement of the retaining sleeve 2 is blocked by the locking spring 6.
In conclusion, the invention provides a high-precision clamping tool handle, the tool handle is tightly matched with a tool through a retaining sleeve 2 sleeved outside a positioning cylinder 3, a ball 21 arranged on the retaining sleeve 2 radially extrudes the positioning cylinder 3, and the positioning accuracy is improved through a matching mode between a point and a surface. When the steel balls are abraded, only the retainer needs to be replaced, and the original knife handle can be recycled, so that the service life of the knife handle is prolonged.
Preferably, the cutter handle is a flange plate 5 type cutter handle, and the flange plate 5 is provided with a threaded hole 51, so that the installation and the precision adjustment are convenient. For the adjustment of the accuracy, the mounting positions of the screws in the screw holes 51 in the flange 5 may be adjusted.
Preferably, the tool holder further comprises a reference ring 4, the reference ring 4 is adjacent to the positioning cylinder 3, the outer diameter of the reference ring 4 is larger than that of the positioning cylinder 3, and a notch 41 is formed in the reference ring 4 and used for reference during precision adjustment.
Preferably, the diameter of the snap spring 6 is larger than the diameter of the positioning cylinder 3, that is, the outer edge of the snap spring 6 protrudes out of the circumference of the positioning cylinder 3, so that the snap spring 6 is in blocking fit with the protection sleeve 2 to prevent the protection sleeve 2 from being separated from the positioning cylinder 3, that is, after the snap spring 6 is clamped into the clamping groove 31, the snap spring protrudes out of the clamping groove 31 to play a role in blocking the retention sleeve 2 from being separated from the positioning cylinder 3.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
