The invention provides an adjustable bolt positioning device which comprises a dial scale with adjustable height and a graduated scale, wherein angle scales are marked on the graduated scale along the circumferential direction, length scales are marked on the graduated scale along the length direction, a slot which is through up and down is arranged in the middle of the graduated scale, and one end of the slotted scale is rotatably connected with the center of the dial scale.

Preferably, a center hole is formed in the circle center of the dial; both ends of the graduated scale are provided with open pores, the central connecting line of the two open pores is superposed with the central line of the open groove, and one open pore is concentrically connected with the central hole.

Preferably, the dial is made of transparent materials; and a pointer is marked at the position of the opening hole concentrically connected with the central hole, the direction of the pointer is overlapped with the central line of the open groove, and the pointer is marked on the graduated scale.

Preferably, an adjusting screw is arranged in the opening.

Preferably, a baffle plate can be detachably connected to the graduated scale.

The bolt positioning device has the beneficial effects that through the matching of the graduated scale and the graduated disc, the bolt mounting accuracy is improved, the bolt positioning speed in irregular arrangement is also improved, and a large amount of time and production cost are saved.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

As shown in fig. 1, the present invention provides an adjustable bolt positioning device, which comprises a dial 1 with adjustable height and a graduated scale 2, wherein the dial 1 is circular and is marked with 360 ° angle graduations along the circumferential direction; the graduated scale 2 is rectangular, length scales are marked along the length direction, a rectangular open slot 21 which is through up and down is arranged in the middle of the graduated scale 2, one end of the graduated scale 2 is rotatably connected with the center of the dial 1, and a pointer 23 is marked at the central rotating hole of the graduated scale 2. The anchor bolt can move in the slot 21 along the length direction of the slot 21, the distance between the anchor bolt and the center of the dial 1 is adjusted according to the scales of the graduated scale 2, the angle is adjusted along with the rotation of the graduated scale 2, and the adjustment angle is determined through the pointing direction of the pointer 23. Still can dismantle on the scale 2 and be connected with baffle 3, baffle 3 can prevent to be located the rag bolt slope in fluting 21, and it keeps vertical to assist it, buries fixedly underground till finally.

As shown in fig. 1 and 2, in an embodiment of the present invention, to ensure the positioning accuracy, the dial 1 is made of transparent material and is located above the scale 2, and the center of the dial is provided with a central hole 11. Both ends of the graduated scale 2 are provided with open pores 22, and the central connecting line of the two open pores 22 is superposed with the central line of the open groove 21. One of the openings 22 is concentrically connected to the central bore 11 and a pointer 23 is marked at this opening 22, which points to coincide with the centre line of the slot 21. All be equipped with adjusting screw 4 in two trompils 22, the cover is equipped with adjusting nut 5 on adjusting screw 4, and the bottom still is equipped with tripod 6, can adjust the height of scale 2 like this through adjusting screw 4, adapts to the rag bolt of different mounting heights.

The arrangement forms of the foundation bolts which are common at present are mainly three: triangular arrangement, symmetrical double-row arrangement and circular arrangement.

Aiming at anchor bolts arranged in a triangular mode, the using method of the bolt positioning device comprises the following steps: firstly, a central point of the equipment is positioned by a simple paying-off method, then the center of the dial scale 1 is superposed with the central point of the equipment, the position of the dial scale 1 is fixed, and then an anchor bolt is placed in a groove 21 of the graduated scale 2 according to the relative size of a site building to determine the position of the anchor bolt. And calculating included angles between the other two foundation bolts and the embedded foundation bolts according to the drawing size, and then rotating the graduated scale 2 according to the graduated scale 1 to determine the positions of the rest foundation bolts to form a triangle. And finally, the height of the graduated scale 2 is adjusted through the adjusting screw rod 4, so that the elevation of the foundation bolt meets the drawing requirement, and the foundation bolt can be embedded and fixed.

For a circular foundation bolt, the use method of the bolt positioning device provided by the invention comprises the following steps: firstly, the circle center is positioned by a simple paying-off method, then the center of the dial 1 is coincided with the circle center, the position of the dial 1 is fixed, at the moment, the circle can be equally divided according to the number of the foundation bolts, the radius and the included angle between two adjacent foundation bolts are calculated, one foundation bolt is placed in the groove 21 of the graduated scale 2, and the position of the foundation bolt is determined. And then sequentially rotating the graduated scale 2 according to the graduated disc 1 to determine the positions of the rest foundation bolts to form circular arrangement.
