Referring to fig. 1-3, the present embodiment provides an adjusting center, which includes a threaded sleeve 2, a base 3 and a threaded rod 1. The screw sleeve 2 is clamped on the base 3 and can rotate on the base 3, that is, the screw sleeve 2 can only rotate on the base 3 and cannot move up and down. The top end of the screw rod 1 is provided with a top bead 4 used for abutting against a workpiece, specifically, the top of the screw rod 1 is provided with a platform, the middle of the top surface of the platform is provided with a spherical hole, a steel ball is driven into the spherical hole, one part of the steel ball is exposed on the platform, and point contact is realized between the steel ball and the corresponding workpiece. The body of rod and the swivel nut 2 screw-thread fit of screw rod 1 can make screw rod 1 activity from top to bottom on base 3 through rotating swivel nut 2. The screw rod 1 is close to or far away from the workpiece in a vertical up-and-down moving mode, and the workpiece is not scratched, so that damage to the workpiece is reduced, and meanwhile, the height is convenient to adjust in the arrangement mode.
In order to prevent the screw 1 from rotating along with the screw sleeve 2 when the screw sleeve 2 is rotated, optionally, a first square hole 11 is formed in the middle of the bottom end of the screw 1, the first square hole 11 extends along the length direction of the screw 1, a guide square rod 5 is matched in the first square hole 11, the bottom end of the guide square rod 5 is installed on the base 3, and the top end of the guide square rod extends into the first square hole 11; when the screw sleeve 2 is rotated, the guide square bar 5 cannot rotate, so that the screw 1 can be limited to rotate by the guide square bar 5. The screw 1 can only move in the length direction of the guide square bar 5, i.e. move up and down in the vertical direction.
Optionally, the thread insert 2 is clamped on the base 3 and can rotate on the base 3 in a specific structural form that an annular clamping groove is formed in the outer wall of the thread insert 2, optionally, the base 3 can be set to be a cylindrical structure, and certainly, the base can also be a square structure or other structures, an annular flange is arranged at the top of the cylindrical structure and clamped in the annular clamping groove, that is, the movement of the thread insert 2 in the vertical direction can be limited through the matching form of the annular clamping groove and the annular flange.
Optionally, in order to realize that the screw sleeve 2 is rotatably disposed on the base 3, the inner diameter of the annular flange needs to be larger than the inner diameter of the annular clamping groove and smaller than the outer diameter of the screw sleeve 2, that is, a certain gap is left between the annular flange and the annular clamping groove when the annular flange is matched with the annular clamping groove, so that the screw sleeve 2 can rotate.
In a possible implementation mode, in order to ensure that the position of the adjusting center does not change when the height is adjusted, the adjusting center is tightly attached to the workbench, specifically, the bottom of the base 3 is provided with a bottom opening, a magnet 6 is installed in the bottom opening, and the adjusting center is tightly attached to the workbench through the magnetic force of the magnet 6; alternatively, the magnet 6 is a powerful magnet; optionally, a second square hole is formed in the middle of the magnet 6, and the bottom end of the guide square rod 5 is clamped in the second square hole, so that the bottom end of the guide square rod 5 is fixed.
Alternatively, the magnet 6 is provided in a circular shape, a circular hole is provided at the bottom of the base 3, the magnet 6 is provided in the circular hole, and the rotating shafts 61 are symmetrically provided on the side wall of the magnet 6. Alternatively, the rotation shaft 61 is provided in the diameter direction of the magnet 6, and alternatively, the rotation shaft 61 is fixed to the magnet 6. The side wall of the base 3 is correspondingly provided with mounting holes for matching with the rotating shafts 61, and the two rotating shafts 61 are mounted in the mounting holes, so that the position of the magnet 6 is limited and the magnet can only rotate by taking the rotating shafts 61 as central axes. Optionally, the upper and lower surfaces of the magnet are made of different materials, so that the magnet 6 has different attractive forces, thereby meeting different compression requirements, for example, when the magnet is arranged on a workbench, the magnet 6 is turned to a strong compression state to prevent the adjustment tip from moving, and when the magnet is not required to be used, the magnet 6 is turned to a weak magnetic force state to facilitate the movement of the adjustment tip. The magnet 6 is restricted from being turned over by the guide square bar 5, and when the turning-over 5 is required, the turning-over can be performed only after the restriction of the guide square bar 5 is released. Optionally, a space is provided in the base 3 in which the magnet 6 can be turned.
In a possible realization, the magnet 6 is provided on a first face with a non-magnetic conductive layer 62; the second face of the magnet 6 or the surface of the non-magnetically permeable layer 62 may be coplanar with the bottom surface of the base when the magnet 6 is flipped. That is, when the magnet 6 is turned to the second face down, the magnetic force is strongest due to the contact between the magnet 6 and the table, and the pressing force is maximized. When the magnet 6 is turned to the surface of the non-magnetic conductive layer 62 to contact the work table, the attraction force between the magnet 6 and the work table is weakened due to the separation of the non-magnetic conductive layer 62, and the magnet is easy to take. Alternatively, the non-magnetic conductive layer 62 may be a non-magnetic conductive rubber layer.
Alternatively, the guide square bar 5 is made of a non-magnetic material to facilitate the movement of the screw 1.
In a possible implementation, the base 3 is provided as a split structure, that is, it is formed by a two-part symmetrical structure cut from the middle of the base 3, that is, a first half seat 31 and a second half seat 32, wherein the first half seat 31 and the second half seat 32 are provided with mounting lugs on both sides, and the mounting is realized by fastening the first half seat 31 and the second half seat 32 through fasteners. Wherein, the first half seat 31 and the second half seat 31 equally divide the annular flange and the mounting hole into two parts so as to facilitate the installation of the screw sleeve 2 and the rotating shaft 61.
For example, when the adjusting device is used specifically, the installed adjusting tip is flatly placed on a workbench, the second surface of the magnet 6 is arranged downwards and is tightly attached to the workbench, the adjusting tip is forcibly moved to a position to be adjusted, the screw sleeve 2 is rotated to enable the screw rod 1 to move upwards, and when the top bead 4 at the top of the screw rod 1 is in contact with a workpiece and is adjusted to a proper position, the rotation is stopped. When the adjustment is not needed or strong adsorption force is not needed, the magnet 6 can be turned to the non-magnetic-conductive layer 62 downwards by moving out the guide square rod 5 in the magnet 6, and the magnet is adsorbed by weak magnetic force, so that the movement is convenient.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
