[0003] 1. using reinforcing steel bar to weld and fix, bolt adjustment personnel manually adjusts bolt to qualified position according to measurement data, uses reinforcing steel bar to be close to bolt to form triangle and welds and connects and welds and fixes it on the measure plate, the adjustment mode causes bolt to deviate due to human behavior, bolt is prone to change during welding, and it needs to remove the reinforcing steel bar when readjusting, the operation is relatively complex in the process, easy to cause damage to bolt, easy to cause rework, needs to cooperate with multiple adjustment personnel, the input personnel is larger, and the adjustment time is longer.

[0004] 2. adjust through nut and screw rod, first, weld and fix nut on bolt measure plate, adjust bolt by rotating screw rod, the screw rod is prone to damage the bolt during adjustment, the adjustment personnel cannot guarantee the adjustment intensity, so the bolt cannot be adjusted to position or the adjustment intensity is too large to cause the bolt to be out of tolerance in the opposite direction, the adjustment personnel cannot directly adjust the bolt to position, and the measurement personnel needs to repeatedly measure and provide measurement data. This method consumes a long time, and the efficiency is low. UTILITY MODEL CONTENTS

[0005] The utility model discloses a high-precision bolt's adjusting device, adopt the scheme, through the adjustment of the scale of the resistance of the scale screw rod to each other and clamping, can improve the adjustment accuracy of bolt, improve the efficiency of bolt adjustment through the device.

[0006] The utility model discloses a high-precision bolt's adjusting device, adopt the scheme, through the adjustment of the scale of the resistance of the scale screw rod to each other and clamping, can improve the adjustment accuracy of bolt, improve the efficiency of bolt adjustment through the device.

[0007] A high-precision bolt's adjusting device, comprising:

[0008] The sleeve ring is placed on the measure plate with the bottom being open, and the top center has a hole, which is matched with the size of the embedded bolt;

[0009] Steel plates are evenly distributed on the circumference of the outside of the sleeve ring, and the steel plates can be detachably fixed on the sleeve ring with a space between the steel plates and the side wall of the sleeve ring.

[0010] The steel plate and the collar sidewall each have corresponding through holes. Each steel plate has a graduated screw. The graduated screw passes through the through holes sequentially through the steel plate and the collar sidewall and is used to abut against the sidewall of the pre-embedded bolt. The size of the two through holes is adapted to the graduated screw, and at least one of the two through holes is a first threaded hole.

[0011] Several of the graduated screws are perpendicular to the sidewall of the pre-embedded bolt and are located on the same horizontal plane.

[0012] Compared to existing technologies, where bolts are prone to shifting during welding and adjustment personnel cannot guarantee the correct adjustment force, leading to either incomplete adjustment or excessive force causing the bolt to deviate from its tolerance, this invention provides a high-precision bolt adjustment device. This solution, through the opposing clamping of several graduated screws and adjustment of the scale, improves the bolt adjustment accuracy and increases the efficiency of bolt adjustment. The specific design includes a collar, steel plates, and graduated screws. The retaining plate serves as a tool for the initial positioning of high-precision bolts, primarily acting as a reinforcement carrier for the bolts and a carrier for the adjustment device. The lower end of the collar can be directly placed on the retaining plate; its lower end is open, and its top center has a hole, allowing the bolt to be temporarily fixed by extending it through the hole. Several steel plates are evenly distributed circumferentially, with spacing between them and the sidewalls of the collar. This allows the graduated screws to remain aligned with the pre-embedded bolts under the constraint of two through holes, preventing screw offset. All graduated screws are located on the same horizontal plane, simultaneously and vertically abutting against the circumferential sidewalls of the pre-embedded bolts. Thus, by adjusting the scale values ​​of each graduated screw, the internal pre-embedded bolts can be precisely adjusted, preventing bolt offset. In this design, the adjustment device can be easily fixed to the retaining plate, and this device is easy to disassemble and reuse, allowing for easy positioning of high-precision bolts and improved adjustment accuracy. Furthermore, the bottom sidewall of the collar can be a non-closed plate, with notches facilitating welding.

[0013] To further optimize the adjustment and simplify the adjustment and installation process, the collar is square and has four sidewall plates; each sidewall plate corresponds to a steel plate; the four graduated screws are orthogonal to each other. The sidewall plates are all welded to the top plate and are made of steel.

[0014] To further optimize the design and facilitate detachment and fixation of the collar, the steel plate is U-shaped, with its upper and lower sides respectively clamping the top of the collar and the bottom of the control plate.

[0015] Further optimized for rapid installation, the lower edge of the steel plate rests on the lower edge of the control plate; the upper edge of the steel plate is positioned above the top of the collar, with a gap between them; the upper edge of the steel plate has several second threaded holes, and the top of the collar has several third threaded holes corresponding one-to-one with the second threaded holes. A reinforcing screw is connected to each second threaded hole, passing through the second threaded hole from top to bottom and connecting to the third threaded hole. In this design, because of the gap between the upper edge of the steel plate and the top of the collar, the steel plate can be quickly inserted during installation, followed by the insertion of the reinforcing screws from top to bottom, so that the reinforcing screws sequentially connect to the second and third threaded holes, thereby completing the temporary fixation of the entire adjustment device.

[0016] To further optimize the design and facilitate external observation of scale changes, the scale markings on the scale screw are located at the end furthest from the pre-embedded bolt.

[0017] To further optimize the process and facilitate the quick installation of the graduated screw, the through hole on the steel plate is a round hole, and the through hole on the collar is a first threaded hole.

[0018] To further optimize the process and prevent bolt damage during adjustment, a pad is provided on the end of the scale screw near the pre-embedded bolt.

[0019] To further optimize the process and ensure the stability of the bolt adjustment, the pad is arc-shaped and has an arc surface that matches the side wall of the pre-embedded bolt.

[0020] The backing plate has a insert rod on its back, and the end of the graduated screw near the pre-embedded bolt has a slot along its length. The backing plate is inserted into the slot via the insert rod and rotated for connection. The center of gravity of the backing plate is located below the insert rod. In this design, the backing plate can achieve a movable connection by inserting its own insert rod into the slot, and the backing plate can rotate freely around the axis of the slot. During the screwing process, because the center of gravity of the backing plate is located below, the screwing process does not easily cause the backing plate to rotate, keeping the backing plate horizontal until it abuts against the pre-embedded bolt through its curved surface.

[0021] Further optimization involves moving the connection point upwards so that the center of gravity is located below the insertion rod, on the center line of the pad perpendicular to its own arc direction, with the insertion rod positioned above the center line; and the slot is located eccentrically above the end of the pre-embedded bolt.

[0022] To further optimize the design, a dovetail-shaped rotating plate is provided at the end of the graduated screw that is away from the pre-embedded bolt, in order to facilitate the rotation of the graduated screw.

[0023] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0024] 1. This utility model provides a high-precision bolt adjustment device. By using several graduated screws that abut against each other and adjusting the scale, the adjustment accuracy of the bolt can be improved, thus increasing the efficiency of bolt adjustment. Furthermore, the use of dimensional scales makes the bolt adjustment data more intuitive, reducing the frequency of repetitive operations by operators and improving both the accuracy and efficiency of adjustment.

[0025] 2. This utility model provides a high-precision bolt adjustment device, which uses a ring scale to precisely adjust the high-precision bolt and the screw fastening method. The adjustment device can be easily fixed on the control plate. The adjustment device is easy to disassemble and can be reused.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0037] Example:

[0038] This embodiment provides a high-precision bolt adjustment device, such as... Figures 1-6 As shown, it includes:

[0039] The collar 9 has an open bottom and is placed on the measure plate 10; the collar 9 has a hole at the center of its top, and the hole is adapted to the size of the pre-embedded bolt 1.

[0040] Steel plates 4 are evenly distributed around the outer circumferential position of the collar 9. The steel plates 4 are detachably fixed to the collar 9 and a gap is left between them and the side wall of the collar 9.

[0041] The steel plate 4 and the collar 9 each have corresponding through holes on their sidewalls. Each steel plate 4 is provided with a scale screw 3. The scale screw 3 passes through the through holes sequentially through the steel plate 4 and the sidewall of the collar 9, and is used to abut against the sidewall of the pre-embedded bolt 1. The size of the two through holes is adapted to the scale screw 3, and at least one of the two through holes is a first threaded hole.

[0042] Several of the graduated screws 3 are perpendicular to the side wall of the pre-embedded bolt 1 and are located on the same horizontal plane.

[0043] Compared to existing technologies, where bolts are prone to shifting during welding and adjustment personnel cannot guarantee the correct adjustment force, resulting in bolts not being properly adjusted or excessive adjustment force causing bolts to deviate from their tolerances, this invention provides a high-precision bolt adjustment device. This solution, through the opposing clamping of several graduated screws and the adjustment of the scale, can improve the bolt adjustment accuracy and increase the efficiency of bolt adjustment. The specific solution includes a collar 9, steel plates 4, and graduated screws 3. The measure plate 10 is a tool for the initial positioning of high-precision bolts, mainly used as a reinforcement carrier and adjustment device for high-precision bolts. The lower end of the collar 9 can be directly placed on the measure plate 10. Its lower end is open, and the top center has a hole, so that the bolt can be inserted into the measure plate 10 through the hole for temporary fixation. Several steel plates 4 are evenly distributed around the circumference and have a gap between them and the side wall of the collar 9. At this time, the graduated screws 3 can be kept facing the pre-embedded bolts 1 under the limit of the two through holes, avoiding the offset of the graduated screws 3. Several graduated screws 3 are all located on the same horizontal plane, so that they can simultaneously and vertically abut against the circumferential side wall of the pre-embedded bolts 1. In this way, by adjusting the scale value of each graduated screw 3, the internal pre-embedded bolts 1 can be adjusted with high precision to prevent the pre-embedded bolts 1 from offsetting. In the above solution, the adjustment device can be easily fixed on the measure plate 10, and the adjustment device is easy to disassemble and can be reused. The high-precision bolts can be easily positioned to improve adjustment accuracy. In addition, the bottom side wall of the collar 9 can be a non-closed plate, which allows for easy insertion and welding through the notch.

[0044] In this embodiment, to improve adjustment accuracy and simplify adjustment and installation steps, the collar 9 is square and has four sidewall plates; each sidewall plate corresponds to a steel plate 4; the four scale screws 3 are orthogonal to each other. The sidewall plates are all welded to the top plate and are made of steel.

[0045] In this embodiment, to facilitate detachment and fix the collar 9, the steel plate 4 is U-shaped, and the upper and lower sides of the steel plate 4 respectively clamp the top of the collar 9 and the bottom of the measure plate 10.

[0046] In this embodiment, for easy and quick installation, the lower side of the steel plate 4 is placed on the lower side of the measure plate 10; the upper side of the steel plate 4 is located above the top of the collar 9, with a gap; the upper side of the steel plate 4 has several second threaded holes, and the top of the collar 9 has several third threaded holes corresponding one-to-one with the second threaded holes. Each second threaded hole is connected to a reinforcing screw 6, which passes through the second threaded hole from top to bottom and connects to the third threaded hole. In this solution, because there is a gap between the upper side of the steel plate 4 and the top of the collar 9, the steel plate 4 can be quickly placed in during installation, and then the reinforcing screws 6 are placed from top to bottom, so that several reinforcing screws 6 are screwed into the second threaded holes and the third threaded holes in sequence, thereby completing the temporary fixation of the entire adjustment device. A square plate extending outward can be welded to the top periphery of the collar 9 for connection with the upper side of the steel plate 4, and the third threaded holes can be formed on the square plate.

[0047] In this embodiment, to facilitate external observation of scale changes, the scale mark 7 on the scale screw 3 is located at the end away from the pre-embedded bolt 1.

[0048] In this embodiment, to facilitate the quick installation of the scale screw 3, the through hole on the steel plate 4 is a round hole, and the through hole on the collar 9 is a first threaded hole.

[0049] In this embodiment, in order to protect the bolts and prevent bolt damage during the adjustment process, a pad 5 is provided on the end of the scale screw 3 near the pre-embedded bolt 1.

[0050] In this embodiment, to ensure the stability of the adjustment bolt process, the pad 5 is arc-shaped and has an arc surface that matches the side wall of the pre-embedded bolt 1.

[0051] The back of the pad 5 has a insert rod, and the end of the graduated screw 3 near the pre-embedded bolt 1 has a slot along its own length. The pad 5 is inserted into the slot through the insert rod and rotated. The center of gravity of the pad 5 is located below the insert rod. In this solution, the pad 5 can be movably connected by inserting its own insert rod into the slot, and the pad 5 can rotate freely around the axis of the slot. During the screwing process of the graduated screw 3, since the center of gravity of the pad 5 is located below, the screwing process of the graduated screw does not easily cause the pad 5 to rotate, so that the pad 5 always moves forward in a horizontal position until the pad 5 abuts against the pre-embedded bolt 1 through the arc surface.

[0052] In this embodiment, in order to move the connection point upward so that the center of gravity is located below the insertion rod, the insertion rod is located above the center of the center line of the pad 5 perpendicular to its own arc direction; and the slot is located above the eccentric position of the end of the pre-embedded bolt 1.

[0053] In this embodiment, to facilitate the rotation of the scale screw 3, the end of the scale screw 3 away from the pre-embedded bolt 1 is equipped with a dovetail-shaped rotating plate 2.

[0054] How this solution works:

[0055] The top of the collar 9 is a 10cm*5cm cuboid with an 8cm diameter hole for mounting the pre-embedded bolt 1. The four side panels have 2cm diameter holes with internal threads at their centers for the calibration screw 3. A 6cm*6cm square plate is welded to the four sides of the top horizontal plane, and each steel plate 4 has a 1cm diameter hole with internal threads for reinforcing the U-shaped steel plate 4 with the screw 6. The top of the U-shaped steel plate 4 has a 1cm diameter hole for bolt connection with the square plate, and its bottom is tightly fitted to the support steel plate 4. The support plate 10 is clamped to the bottom of the steel plate 4 by the reinforcing screw 6, thus fixing the adjustment device. The side of the steel plate 4 has a 2.2cm diameter hole for installing the calibration screw 3 and for reading the screw-in values.

A square plate with a diameter of 6cm*3cm*5mm is welded on the four sides of the 10cm*10cm cuboid. A hole with a diameter of 1cm is drilled 1.5cm away from the center of the square plate and threaded to reinforce the installation of the screw 6. A hole with a diameter of 2cm is also drilled on the 10cm*5cm side of the cuboid and threaded to install the graduated screw 3.

The other end has a 1.1cm deep hole at its center for installing an arc-shaped pad 5, which is installed on the collar 9 and passes through the steel plate 4.

[0061] The reinforcing screws 6 are all externally threaded 8 with a diameter of 1cm, used to connect the square plate and the steel plate 4.

[0062] The backing plate 5 has a curvature of 2cm, a thickness of 5mm, and a width of 2cm. A cylinder with a diameter of 1cm and a length of 1cm protrudes from the middle of its curved back and is installed at the end of the graduated screw 3. It is used to protect the pre-embedded bolt 1.

[0063] Step 2: Assembly and adjustment of usage instructions:

[0064] First, fit the collar 9 onto the pre-embedded bolt 1. Connect the steel plate 4 to the collar 9 with the reinforcing bolt and tighten the reinforcing bolt. The three parts, the protective plate 10 and the bottom of the steel plate 4, are tightly connected together. Fix the square collar 9. Next, pass the scale screw 3 through the steel plate 4 and rotate it through the collar 9. Finally, install the arc-shaped pad 5 onto the end of the scale screw 3. The adjustment device is now assembled.

[0065] The operator can adjust the pre-embedded bolt 1 by rotating the scale screw 3. The screw-in dimension can be obtained according to the scale mark 7 on the scale screw 3, so as to accurately adjust the pre-embedded bolt 1.
