This creation provides a designer of a center vise device.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, the implementation method and the schema are as follows: See the first to fifth figures, this creation provides a central tiger. The clamp device comprises: a vise body (A) that is not adjustable, the vise body (A) is provided with a guide groove (A1), a lead screw 20, and the lead screw 20 is an integrally formed rod body. The two sides of the screw 20 are respectively provided with positive and reverse threads 21 and 22, and an annular positioning protrusion 23 is arranged in the center of the lead screw 20; a first clamping group 30 and a second clamping group 40, the first The two clamping jaw groups 30 and 40 are disposed to slide in the vise body (A) guiding groove (A1), and the first clamping group 30 is provided with a rotating internal thread 31 corresponding to the forward screw thread 21 of the lead screw 20; So that the first clamping group 30 is obtained in the aforementioned lead screw 20 The second clamping group 40 is provided with a counter-rotating internal thread 41 corresponding to the counter-rotating screw 22 of the lead screw 20, so that the second clamping group 40 is rotated when the lead screw 20 rotates. The action of clamping or loosening is generated, and the first and second clamping groups 30, 40 can be clamped and clamped together, and the loose and the same action; the first and second clamping groups 30, 40, A positioning block group 50 and the lead screw 20 constitute an adjustable portion (B). The positioning block group 50 is provided with an annular positioning groove 51 for engaging the annular positioning convex portion 23, and the positioning block group 50 is provided by an upper portion. The positioning block 60 and the lower positioning block 70 are combined. The lower positioning block 70 is provided with two recessed recesses 71. The top positioning block 60 has a top pressing block 62 protruding from the lower side of the upper positioning block 60. 60 is provided with two screw holes 61 corresponding to the abutting recessed holes 71. The vise body (A) is provided with guiding grooves (A2) on both sides of the guiding groove (A1), and the two top pressing blocks of the upper positioning block 60 62 is embedded in the guiding groove (A2); two pressing screws 80, the two pressing screws 80 are respectively locked to the two screw holes 61, and penetrated into the foregoing When the recessed holes 71 are pressed to lock the two tensioning screws 80 (as shown in FIG. 5), the two upper pressing blocks 62 of the upper positioning block 60 abut against the guiding grooves (A2). The lower positioning block 70 abuts against the guiding groove (A2) to complete the positioning of the adjustable portion (B), and loosens the two pressing screws 80 (as shown in the fourth figure), and the adjustable portion (B) ) It is possible to adjust the center position of the fine adjustment with the rubber hammer and the precision gauge to ensure the accuracy of the center accuracy and the convenience of fine adjustment.

In the center vise device, the tensioning screw 80 adjusts the range of the elastic distance so as not to disengage the annular positioning convex portion 23 from the annular positioning groove 51.

In the center vise device, the two ends of the lead screw 20 are provided as tool sleeves 24, 25.

In summary, the original reason for the creation of this case is that the center position of the conventional center vise equipment may be displaced after a period of processing on the working bed, resulting in inaccurate accuracy. The conventional center vise can not be adjusted after the positioning block group is positioned and fixed. In this creation, as long as the tightening screw 80 is loosened, the adjustment of the adjustable portion (B) can be performed, and after the adjustment, the tightening screw 80 is completed to complete the positioning of the adjustable portion (B). Therefore, the shifting of the center position of the conventional center vise produces a problem of inaccurate accuracy, which can be easily eliminated by this creation.

It can be seen from the above that the center vise device of this creation is indeed the first in the industry and meets the novel requirements of the new patent, and its comprehensive and innovative design conforms to the progressive requirements of the new patent, and includes the vise body. And the adjustable part is composed, and when the tightening and tightening screw is adjusted, the adjustable part can finely adjust the center precision, and the tightening screw is used to complete the positioning of the adjustable part, which is in line with better industrial utilization.

The foregoing description of the preferred embodiments of the present invention is specifically described as a technical feature of the present invention; however, those skilled in the art can make changes and modifications to the present invention without departing from the spirit and principles of the present invention. Such changes and modifications shall be covered by the scope of the following patent application.

In summary, the creation department provides a center vise device, which has indeed achieved all the purposes of this creation. The spatial pattern of the combined structure is not found in similar products, nor has it been disclosed before the application, and has been in compliance with the Patent Law. It is stipulated that the application should be made according to law.
