Description

Technical Field

[0001] This utility model relates to the field of component splicing technology, and in particular to a precision splicing device for prefabricated building components. Background Technology

[0002] Prefabricated building components are prefabricated building parts in factories, including beams, slabs, and columns. After being transported to the construction site, they are assembled using reliable connection methods, quickly building a structure like assembling building blocks. However, during use, they often require further assembly. Specialized equipment is used to ensure the precise installation of these components. This equipment has a high-precision positioning system that can accurately identify the position and angle of the components. Its sensors are accurate to the millimeter level, enabling precise alignment of beams and columns during assembly and preventing misalignment. This equipment also has multiple adjustment functions, such as fine-tuning of the components in the horizontal and vertical directions. Precise displacement control is achieved through hydraulic devices and mechanical screw drives, ensuring that each component is tightly assembled. It's like installing a precise navigator and adjuster for the assembly. However, weak assembly often leads to breakage and cracking during use, making the assembly mechanism particularly important.

[0003] Existing splicing mechanisms typically consist of multiple high-precision robotic arms, positioning jigs, and transmission devices. The robotic arms possess multi-degree-of-freedom flexible movement capabilities, enabling them to precisely grasp and move building components in three-dimensional space. The positioning jigs, through special design, can closely fit specific parts of the components, using strong clamping force to ensure the components remain stable during splicing. The transmission device can precisely control the movement speed and position of the robotic arms and positioning jigs, achieving millimeter-level precision positioning. During operation, the robotic arms move different building components step by step to the designated position according to a pre-set program. The positioning jigs assist in the initial fixation of the components, and then the transmission device fine-tunes the position to ensure that the splicing gaps between the components meet the design requirements, thereby achieving precise splicing. However, this splicing method is prone to gaps during splicing, which cannot be completely closed, leading to safety hazards during use and affecting the splicing effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a precision splicing device for prefabricated building components, which aims to improve the problem in the prior art that gaps are easily generated during splicing, making it impossible to completely close the gaps, resulting in safety hazards during use and affecting the splicing effect.

[0006] As a further description of the above technical solution:

[0007] The telescopic mechanism includes a spring 1, the rear side of which is fixedly connected to the front side of the rear base. A stop bar is fixedly connected to the front side of the spring 1, and the front side of the stop bar is slidably connected to the rear side of the front base.

A connecting rod 1 is fixedly connected to the left side of the trapezoidal block near its edge. A pulling rod is slidably connected to the outer wall of the connecting rod 1 near its center. A fixing block is slidably connected to the outer wall of the connecting rod 1 near its edge. A square groove is formed inside the fixing block, and the inner wall of the square groove is slidably connected to the outer wall of the trapezoidal block.

[0008] As a further description of the above technical solution:

[0009] A fixing buckle is fixedly connected to the outer wall of the bidirectional threaded rod near the middle, and the front side of the fixing buckle is fixedly connected to the rear end of the elongated slide groove.

[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] A connecting rod three is fixedly connected to the top front end of the front base near the middle, and a support column is fixedly connected to the rear end of the connecting rod three.

[0016] As a further description of the above technical solution:

[0017] Multiple rear limiting plates are fixedly connected to the top rear end of the front base near the middle, and multiple wheels are fixedly connected to the bottom perimeter of the front base.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the two assembly components to be installed are first placed inside the front and rear limit plates. Then, the sliding rod compresses the spring three and drives the long slide groove to move backward. At this time, the motor is started, driving the threaded sleeve to rotate, and then driving the bidirectional threaded rod to push the connecting rod two to move inward and outward. At this time, the connecting rod two will drive the connecting block and the positioning post to adjust to the rear side of the circular hole of the assembly component. Then, the sliding rod is released, and the square shell will drive the sliding rod to return to its original position. At this time, the positioning post is stuck in the circular hole. Then, the motor is started again, and the positioning post will drive the assembly component to move inward until there is no gap. This achieves the effect of making the assembled components more compact and preventing gaps.

[0022] 2. In this utility model, after the assembly components are assembled, the pull rod is lifted, which will squeeze the connecting rod one. At this time, the connecting rod one will drive the trapezoidal block to squeeze the spring two and leave the square groove of the fixed block. Then the pull rod drives the connecting rod one and the trapezoidal block to move forward. At this time, the trapezoidal block drives the stop bar to return to the interior of the rear base under the reset of the spring one. This realizes the function of allowing the assembly components to be placed on the ground by opening the stop bar after the assembly is completed. Attached Figure Description

[0040] Working principle: First, place the two assembly components 25 to be installed inside the front limit plate 22 and the rear limit plate 24. Then, pull the sliding rod 6 backward. The sliding rod 6 will compress the spring 3 5 and drive the long strip slide 7 to move backward. At this time, the motor 8 will be started. The motor 8 will drive the threaded sleeve 9 to rotate. The threaded sleeve 9 will drive the bidirectional threaded rod 10 to rotate. The bidirectional threaded rod 10 will push the connecting rod 2 11 to move inward and outward. At this time, the connecting rod 2 11 will drive the connecting block 12 and the positioning post 14 to be adjusted to the rear side of the circular hole 21 of the assembly component 25. Then, release the sliding rod 6. The square shell 4 will drive the sliding rod 6 to return to its original position. At this time, the positioning post 14 will be stuck in the circular hole 21. Then, start the motor 8 again. At this time, the positioning post 14 will drive the assembly component 25 to move inward until there is no gap. At this time, the connecting plate 19 and the support post 18 are used to fix it, which can make the assembled components tighter and prevent gaps.

[0041] After the assembly component 25 is assembled, lift the pull rod 206. The pull rod 206 will then press the connecting rod 205. At this time, the connecting rod 205 will drive the trapezoidal block 204 to move inward. Then, while pressing the spring 203, the trapezoidal block 204 will leave the square groove 208 of the fixing block 207. Then, the pull rod 206 will drive the connecting rod 205 and the trapezoidal block 204 to move forward. At this time, the trapezoidal block 204 will drive the stop rod 201 back into the rear base 3 under the reset of the spring 202. The assembly component 25 will then fall. After placement, push the pull rod 206 to make the trapezoidal block 204 slide back into the square groove 208. At the same time, the stop rod 201 will stretch the spring 202, thus enabling the assembly component 25 to be placed on the ground by opening the stop rod 201 after assembly.
