Abstract
Description
Technical Field
[0001] This technical solution relates to the field of assembly technology, specifically a general-purpose leveling tool. Background Technology
[0002] The plate assembly method is a ship section assembly process, commonly used in steel structure assembly. It uses plate as a temporary connecting component, and through precise positioning and welding to fix adjacent sections, it achieves rapid docking of the hull structure while controlling accuracy and deformation. It is widely used in the shipbuilding industry.
[0003] The existing method of assembling the steel plates requires that, in order to ensure the flatness of the two steel plates before welding, the steel plates must be leveled first, and then the steel plates must be welded one by one between the steel plates to maintain the flatness of the plate surface. After welding, the steel plates need to be cut. The cutting, grinding and repair processes increase the labor and time consumption, reduce efficiency, and the steel plates cannot be reused, resulting in material waste and high cost. Summary of the Invention
[0004] This technical solution addresses the issue of high costs associated with the non-reusability of the mounting plates used in the mortise and tenon joint method by providing a universal leveling fixture.
[0005] The purpose of this technical solution is achieved as follows:
[0006] A general-purpose leveling fixture includes a first adjusting rod, a second adjusting rod, and a leveling frame. The first and second adjusting rods are movably mounted on the leveling frame, which includes:
[0007] The connecting section has the first adjusting rod and the second adjusting rod respectively connected to opposite sides of the connecting section;
[0008] An extension segment is disposed on the connecting segment and extends downward;
[0009] A pressing section is provided at the lower part of the extension section. The pressing section has a pressing surface. The first adjusting rod is moved to adjust the span distance between the pressing surface and the first adjusting rod. The second adjusting rod is moved to adjust the pressure of the second adjusting rod.
[0010] Through the above technical solution, a universal leveling fixture, when in normal use, is applied to two misaligned workpieces to be leveled. The pressing section of the leveling frame and the first adjusting rod are placed on opposite sides of the same workpiece. The first adjusting rod is adjusted to move the pressing section closer to the workpiece until the pressing surface at the top of the pressing section contacts the workpiece to form a clamping fixation, completing the initial positioning. At this point, the second adjusting rod is positioned above the higher workpiece on the other side. Based on the fixed position of the leveling frame, the second adjusting rod is adjusted to press down on the corresponding workpiece, applying controllable vertical pressure. This forces the higher workpiece to gradually descend until it aligns with the fixed lower workpiece, achieving a aligned and closed state. The first adjusting rod maintains the span stability of the pressing surface, while the second adjusting rod precisely controls the downward pressure. The two rods work together to dynamically compensate for the height difference between the two workpieces. After completion, the fixture can be disassembled and reused without damage, eliminating the need for welding or destructive fixing, thus reducing production costs.
[0011] Preferably, both the first and second adjusting rods have threaded portions, and the connecting section has two threaded holes. The first and second adjusting rods are respectively connected to the two threaded holes through the threaded portions.
[0012] Through the above technical solution, the threaded parts of the first adjusting rod and the second adjusting rod are screwed into the threaded holes on both sides of the leveling frame connecting section, respectively. By rotating the first adjusting rod and the second adjusting rod, they are driven to move their positions axially along the threaded holes, thereby improving the adjustment accuracy, maintaining the stability of the adjustment state, and improving operability.
[0013] Preferably, both the first and second adjusting rods have a screw head at their ends.
[0014] Through the above technical solution, the screwing heads at the ends of the first and second adjusting rods provide a point for direct manual force application. By rotating the screwing heads, the threaded part is driven to simultaneously screw in or out of the threaded hole of the connecting section, simplifying the operation.
[0015] Preferably, the first adjusting rod and the second adjusting rod are respectively fitted with a bearing seat, and each bearing seat has a groove. The ends of the first adjusting rod and the second adjusting rod each have an embedding part for embedding into the corresponding groove.
[0016] The bearing seat has a mounting hole along its circumferential sidewall. The mounting hole is connected to a limiting member. The end of the limiting member protrudes into the inner wall of the groove. The first adjusting rod and the second adjusting rod each have a limiting ring groove for the corresponding limiting member to be inserted.
[0017] Through the above technical solution, the embedded parts at the ends of the first and second adjusting rods are respectively inserted into the grooves of the corresponding bearing seats. At this time, the position of the limiting ring groove is aligned with the corresponding through-hole of the mounting hole, so that the limiting part can pass through and connect to the mounting hole until its end protrudes and is embedded in the limiting ring groove. The embedded part can rotate freely in the groove, realizing the circumferentially rotatable and axially anti-dislodgement locking operation between the rod body and the bearing seat. The bearing seat supports the rod body and enhances the rod body's resistance to lateral loads, which is suitable for high vibration conditions.
[0018] Preferably, a bearing component is installed in each of the grooves, and the embedding part has a guide shaft protruding for embedding the corresponding bearing component.
[0019] With the above technical solution, the bearing component is placed in the groove, and the guide shaft of the embedded part is precisely inserted into the bearing component. The sliding friction when the adjusting rod rotates is converted into rolling friction by the bearing component. The guide shaft rotates freely in the bearing component. The low resistance characteristics of the bearing make the threaded pair transmission smoother and optimize the adjustment effect.
[0020] Preferably, the bottom of the groove is provided with a relief groove, and the position of the relief groove corresponds one-to-one with the guide shaft.
[0021] The above technical solution aligns the groove with the end of the guide shaft of the embedded part, providing longitudinal clearance space and avoiding frictional resistance caused by rigid contact between the guide shaft and the bottom of the groove.
[0022] Preferably, the bottom of the bearing seat has anti-slip texture.
[0023] Through the above technical solution, the bearing seat contacts the surface of the workpiece being leveled through anti-slip texture. The contact friction between the texture and the workpiece increases the static friction force, resists the horizontal force generated during the leveling process, prevents the bearing seat from slipping on the contact surface with the workpiece, and improves stability.
[0024] Preferably, the end of the limiting member has an inclined annular surface.
[0025] With the above technical solution, the end of the limiting component with the inclined annular surface is installed facing the mounting hole. The inclined direction of the inclined annular surface makes the end of the limiting part gradually narrow along the installation direction, which improves the ease of installation and further reduces frictional resistance.
[0026] Preferably, the opposing sidewalls of the leveling frame are provided with weight-reducing grooves.
[0027] By using the above technical solution, the material in the non-load-bearing area is reduced through the symmetrically distributed weight-reducing groove cavity structure. While maintaining the overall rigidity of the connecting section, extension section and pressure section, the total weight of the tooling is reduced, allowing the operator to quickly adjust the moving speed of the leveling frame on the adjustment rod, resulting in a lightweight structure.
[0028] The key and beneficial technical effects of this technical solution compared to existing technologies are:
[0029] 1. This technical solution uses the first adjusting rod and the pressing section to clamp and fix the lower workpiece, and the second adjusting rod to precisely press down the higher workpiece, dynamically compensating for the height difference to align the two sides. It can be reused, reducing tooling wear and tear costs. Attached Figure Description

[0037] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.
[0038] Example:
[0039] A general-purpose leveling fixture includes a first adjusting rod 1, a second adjusting rod 2, and a leveling frame 3. The first adjusting rod 1 and the second adjusting rod 2 have similar structures and are generally rod-shaped. The leveling frame 3 is movably mounted on the first adjusting rod 1 and the second adjusting rod 2. The opposing side walls of the leveling frame 3 are provided with weight-reducing grooves 18. The first adjusting rod 1, the second adjusting rod 2, and the leveling frame 3 can all move relative to each other to change their positions.
[0040] See Figure 2 and Figure 3 The first adjusting rod 1 and the second adjusting rod 2 are respectively provided with a bearing seat 8. A groove 9 is opened on one side of each bearing seat 8. A bearing component 14 is engaged and installed in each groove 9. One end of the first adjusting rod 1 and the second adjusting rod 2 is provided with an insert part 10 and the other end is provided with a screwing head 7. The insert part 10 is also provided with a guide shaft 19, which protrudes from the end of the insert part 10 away from the screwing head 7. The size of the insert part 10 is adapted to fit the groove 9. The guide shaft 19 is correspondingly inserted into the inner side of the corresponding bearing component 14 and rotated by the bearing component 14.
[0041] Each bearing seat 8 is also provided with mounting holes 11. Several mounting holes 11 are provided; in this embodiment, three mounting holes 11 are provided on each bearing seat 8's circumferential sidewall. The three holes are evenly distributed along the circumferential sidewall and extend through to the inner wall of the groove 9, forming a through channel. Each insert 10 also has a limiting annular groove 13 on its surface. The limiting annular groove 13 is annular, and when the insert 10 is fitted into the groove 9, the axial position of the limiting annular groove 13 is exactly aligned with the axis of the three mounting holes 11. Each mounting hole 11 is fitted with a limiting member 12, which can be tapered. Each limiting member 12 has an inclined annular surface 17 at its end. The inclined annular surface 17 makes the end of the limiting part have a tapered structure with a gradually decreasing outer diameter. The limiting member 12 is guided to be inserted into the mounting hole 11 through the inclined annular surface 17. The limiting member 12 can be threaded into the mounting hole 11. The end of the limiting member 12 along the insertion direction protrudes from the inner wall of the groove 9 and extends into the limiting ring groove 13, restricting the corresponding embedded part 10 from axially disengaging from the groove 9. The circumferentially distributed limiting points effectively resist torque in all directions, ensuring that the embedded part 10 always remains coaxially positioned with the shaft seat 8 when the adjusting rod rotates.
[0042] Both the first adjusting rod 1 and the second adjusting rod 2 have threaded portions 5, which are located between the corresponding embedded portions 10 and the screwing head 7. The leveling frame 3 includes a connecting section 31, an extension section 32, and a pressing section 33. The connecting section 31 has threaded holes 6 symmetrically opened at its left and right ends along its length. The first adjusting rod 1 and the second adjusting rod 2 are threadedly connected to the threaded holes 6 on both sides through the threaded portions 5. By rotating the rods clockwise or counterclockwise, the left and right threaded holes 6 are set to rotate in opposite directions (e.g., left end left). (Rotating, right-hand rotation) drives the first and second adjusting rods to extend or retract synchronously along the corresponding threaded hole 6 axially; the extension section 32 is respectively set between the connecting section 31 and the pressing section 33. The extension section 32 is connected to the front side of the connecting section 31 and extends downward, so that it cooperates with the connecting section 31 to form an inverted T-shaped main frame. The extension section 32 extends downward, and the pressing section 33 bends towards the side close to the connecting section 31. The pressing section 33 has a pressing surface 4, which is set as the end face of the pressing section 33 near the connecting section 31.
[0043] See Figure 4 , Figure 5 and Figure 6 The pressing section 33 of the leveling frame 3 and the first adjusting rod 1 are respectively arranged on both sides of the lower side plate 100. The plate 100 can be a T-shaped material, etc. By rotating the first adjusting rod 1, its threaded part 5 is driven to advance axially along the threaded hole 6 of the connecting section 31. Since the bearing 8 of the first adjusting rod 1 abuts against the upper end face of the plate 100, its position is relatively fixed, thereby driving the leveling frame 3 to move, reducing the span distance between the pressing surface 4 and the first adjusting rod 1. The pressing section 33 on the leveling frame 3 is closer to the lower end face of the plate 100. Until the pressure surface 4 abuts against the lower end face of plate 100, forming a rigid clamping reference and completing the span locking; the second adjusting rod 2 is directly facing the upper surface of plate 200, and plate 200 is in a high position relative to plate 100. By rotating the screw head 7 of the second adjusting rod 2 in the opposite direction, the rotational motion is converted into vertical downward linear pressure by the thread transmission, forcing plate 200 to sink evenly. When the two plates are completely aligned, the limit maintains the leveling state and is stable. The modular structure can be directly put into the next station for reuse.
[0044] The specific work process of this plan is as follows:
[0045] This technical solution utilizes the pressing section 33 of the leveling frame 3 and the first adjusting rod 1, which are placed on opposite sides of the workpiece to be leveled on the same side. The first adjusting rod 1 is adjusted to move the pressing section 33 closer to the first plate until the pressing surface 4 at the top of the pressing section 33 contacts the first plate to form a clamping fixation, completing the initial positioning. At this time, the second adjusting rod 2 is located above the second plate, which is higher on the other side. Based on the fixed position of the leveling frame 3, the second adjusting rod 2 is adjusted to press down on the corresponding second plate, applying controllable vertical pressure, forcing the second plate to gradually descend until it is aligned and leveled with the fixed first plate. The two plates reach an aligned and closed state. The first adjusting rod 1 maintains the span stability of the pressing surface 4, and the second adjusting rod 2 precisely controls the downward pressure. The two rods work together to achieve dynamic compensation of the height difference between the two workpieces. After completion, the tooling can be disassembled and reused without damage, without welding or destructive fixing, reducing production costs.
