At the present stage, the adjusting device with high intelligence degree and high precision belongs to the combination of a stepping motor and a screw rod, but the application scenes of the stepping motor and the screw rod are limited, and generally, the adjusting device has two limitations, namely, the limitation of high cost on one hand, and the limitation of the length of the screw rod on the other hand.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a precision machinery anchor clamps with adjust structure can realize that the high accuracy is adjusted, and is applicable to the constrictive occasion of installation space, and is with low costs.

In order to achieve the aim, the precision mechanical clamp with the adjusting structure comprises an adjusting block and a square rotating rod, wherein a first threaded hole is formed in the middle of the adjusting block, and an adjusting bolt is connected to the first threaded hole in a threaded manner; second threaded holes are respectively formed in two sides of the first threaded hole, and fixing bolts are connected to the second threaded holes in a threaded mode; the head of adjusting bolt is fixed with the fixture block, first recess has been seted up on the terminal surface of fixture block perpendicular to adjusting bolt axial lead, the left and right sides face of first recess intercommunication fixture block, the left and right sides face center of fixture block runs through and is provided with first through-hole, it has the column sleeve to rotate in the first recess to be connected with, the telescopic rotation plane of column and adjusting bolt axial lead coplanar, square dwang passes column sleeve and both ends threaded connection has the stopper, the size and the first through-hole phase-match of stopper.

The principle and the advantages are as follows:

1. the setting of regulating block, second screw hole and fixing bolt can realize the holistic connection function of dismantling of device through twisting fixing bolt to and realize the stable fixed effect.

2. The first threaded hole and the adjusting bolt are arranged, accurate adjustment can be achieved within a short distance, and the adjustment accuracy depends on the thread pitches of the adjusting bolt and the first threaded hole. Because the device wholly possesses the function of dismantling the connection, consequently if need improve the precision, then change regulating block and adjusting bolt can, therefore extensive applicability, the processing cost is low simultaneously.

3. The clamping block and the square rotating rod are arranged, on one hand, when the cylindrical sleeve is sleeved on the square rotating rod, the square rotating rod is rotated to drive the adjusting bolt to rotate, and the operation is simple and labor-saving; on the other hand, when the inconvenient square dwang of operation of rotation space undersize, can give way the shape dwang and slide under the restriction of form sleeve cover to let the stopper enter into first through-hole, make square dwang rotatable 90, with adjusting bolt axial lead syntropy, realize the extension of length, in order to facilitate the regulation. At the moment, the adjusting bolt can be screwed only by adding a square rotating rod on the limiting block at the end part of the square rotating rod. The operation is simple and labor-saving, and the applicability is wide.

Furthermore, a second through hole penetrates through the side face of the limiting block, and the orientation of the second through hole is perpendicular to the square rotating rod.

The setting of second through-hole can conveniently add a square dwang to form right angle spanner, then can realize moving adjusting bolt's twisting, easy operation is laborsaving, and belongs to detachable construction, and the installation is dismantled also very conveniently.

Furthermore, the limiting block is spherical. Avoid hurting hands.

Further, an arc-shaped chamfer is arranged at the opening of the first through hole.

The arrangement of the arc-shaped chamfers is convenient for the spherical limiting block to smoothly enter the first through hole.

Drawings

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: second through-hole 1, stopper 2, square dwang 3, column sleeve 4, fixture block 5, first through-hole 6, fixing bolt 7, regulating block 8, first recess 9.

Examples

A precision mechanical clamp with an adjustment mechanism, substantially as shown in figure 1: the adjustable adjusting device comprises an adjusting block 8 and a square rotating rod 3, wherein a first threaded hole is formed in the middle of the adjusting block 8, and an adjusting bolt is connected to the first threaded hole in a threaded manner; second threaded holes are formed in two sides of the first threaded hole respectively, and fixing bolts 7 are connected to the second threaded holes in a threaded mode.

The head of adjusting bolt is fixed with fixture block 5, first recess 9 has been seted up on the terminal surface of fixture block 5 perpendicular to adjusting bolt axial lead, first recess 9 intercommunication fixture block 5's the left and right sides face, the left and right sides face center of fixture block 5 runs through and is provided with first through-hole 6, it is connected with cylindrical sleeve 4 to rotate in the first recess 9, the rotation plane and the adjusting bolt axial lead coplanar of cylindrical sleeve 4, square dwang 3 passes cylindrical sleeve 4 and both ends threaded connection has stopper 2, stopper 2's size and first through-hole 6 phase-match, first through-hole 6 can be bigger a little to stopper 2 gets into, and first through-hole 6 is inside to set up to the arc passageway simultaneously, and sleeve 4 also can be set up a little to improve the smoothness degree that stopper 2 got into first through-hole 6.
