The present invention 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, features and effects of the present invention, the implementation method and the schema are as follows:

Referring to the first to fifth figures, the present invention provides a center vise device comprising: a vise body (A) that is not adjustable, and the vise body (A) is provided with a guide groove (A1); The lead screw 20 is an integrally formed rod body, and the two sides of the lead screw 20 are respectively provided with positive and reverse threads 21 and 22, and an annular positioning convex portion 23 is arranged in the center of the lead screw 20; The clamping group 30 and the second clamping group 40, the first and second clamping groups 30, 40 are arranged to slide in the vise body (A) guiding groove (A1), and the first clamping group 30 A forward screw internal thread 31 corresponding to the forward screw thread 21 of the lead screw 20 is provided, so that the first clamp group 30 is obtained in the 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.
