Description

Technical Field

[0001] The utility model relates to the technical field of ships, and more specifically to a ship workpiece assembly support and positioning structure. Background Art

[0002] Ships refer to water vehicles used to transport goods, personnel or carry out other specific activities on water. There are many types of ships, including cargo ships, passenger ships, fishing boats, tankers, aircraft carriers, etc. The assembly of ship parts is an important part of the shipbuilding process. It involves the process of assembling various components and parts into the final ship assembly or system. However, the support and positioning structures commonly used in the assembly of ship parts are usually fixed. Fixed support and positioning structures cannot compensate or adjust small position deviations during the assembly process, which may limit the assembly accuracy to a certain extent, especially for the assembly of ship parts with high precision requirements.

[0009] Among them, the fixing assembly includes a lower tube clamp, an upper tube clamp, a T-shaped threaded rod, and a threaded knob. The lower tube clamp is fixedly connected to the top of the connecting base, the upper tube clamp is movably installed on the top of the lower tube clamp, the T-shaped threaded rod is rotatably installed at the bottom of one end of the lower tube clamp, and the threaded knob is threadedly sleeved on the T-shaped threaded rod.

[0010] It also includes a clamping device, which has two groups of clamping devices symmetrically fixedly installed on the bottom of the first support frame and the second support frame.

[0011] Among them, the clamping device includes a limiting shell, a support block, a double-headed threaded rod, a movable splint, and a rotating handle. The limiting shell is fixedly installed on the bottom of the second support frame, the support block is fixedly installed inside the limiting shell, the double-headed threaded rod is rotatably installed inside the limiting shell, and is movably sleeved on the inner surface of the support block. The movable splint is provided with two groups of symmetrical and movably sleeved on the left and right ends of the double-headed threaded rod, and the rotating handle is fixedly connected to the right end of the limiting shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the above scheme, the utility model is provided with a spacing adjustment device, which moves the threaded tube threadedly connected with the first threaded rod by rotating the first threaded rod, and the movement of the threaded tube drives the second support frame to move closer to or away from the first support frame, thereby changing the spacing between the workpieces. After the positioning is adjusted, the upper tube clamp is rotated so that the upper tube clamp and the lower tube clamp are connected to the outer surface of the threaded tube, and the threaded knob is rotated so that the threaded knob applies a downward force to tightly clamp the threaded tube. By utilizing the above structure, the spacing between the workpieces is adjusted to compensate for the position deviation occurring during the assembly process, thereby improving the effect of assembly accuracy.

[0014] The double-headed threaded rod is driven to rotate by turning the rotating handle, and the rotation of the double-headed threaded rod causes the two sets of movable clamps movably sleeved thereon to move toward the supporting block under the limiting action of the limiting shell. At this time, the two sets of movable clamps shrink and clamp the workpiece to be assembled. Utilizing the above structure, a higher tightness is achieved when clamping the workpiece, and installation and disassembly are more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

A connecting base 45 is fixedly installed on the top of the first support frame 1, and a fixing component 46 is fixedly installed on the top of the right end of the connecting base 45, and the fixing component 46 is arranged on the outer surface of the threaded tube 44.

[0027] Among them, the fixing assembly 46 includes a lower tube clamp 461, an upper tube clamp 462, a T-shaped threaded rod 463, and a threaded knob 464. The lower tube clamp 461 is fixedly connected to the top of the connecting base 45, the upper tube clamp 462 is movably installed on the top of the lower tube clamp 461, the T-shaped threaded rod 463 is rotatably installed at the bottom of one end of the lower tube clamp 461, and the threaded knob 464 is threadedly sleeved on the T-shaped threaded rod 463; the T-shaped threaded rod 463 is composed of a short threaded rod and a movable rod to form a T-shaped structure, and the threaded knob 464 is rotated to make the lower tube clamp 461 fit tightly with the upper tube clamp 462, so as to firmly clamp the threaded tube 44. Because the fixed end of the connecting base 45 is at the top of the first support frame 1, it provides higher stability, so that the first support frame 1 and the second support frame 3 are not easy to change position due to vibration and other reasons after positioning.

[0028] The invention also includes a clamping device 5 , which comprises two groups of clamping devices 5 symmetrically fixedly installed at the bottom of the first support frame 1 and the bottom of the second support frame 3 .

[0029] Among them, the clamping device 5 includes a limiting shell 51, a support block 52, a double-headed threaded rod 53, a movable splint 54, and a rotating handle 55.

[0030] The working process of the utility model is as follows:

[0031] After the staff puts the workpiece to be assembled into the clamping device 5, the double-headed threaded rod 53 is driven to rotate by turning the rotating handle 55. The rotation of the double-headed threaded rod 53 causes the two sets of movable clamping plates 54 movably sleeved thereon to move toward the support block 52 under the limiting action of the limiting shell 51. At this time, the two sets of movable clamping plates 54 shrink and clamp the workpiece to be assembled. By rotating the first threaded rod 42, the threaded tube 44 threadedly sleeved with the first threaded rod 42 is moved, the threaded tube 44 is connected to the second fixed block 43, the second fixed block 43 is connected to the second support frame 3, and the threaded tube 44 moves It will drive the second support frame 3 to move closer to or away from the first support frame 1, thereby changing the distance between the two groups of clamping devices 5, so that the distance between the workpieces changes. After the positioning is adjusted, the upper tube clamp 462 is rotated to make the upper tube clamp 462 and the lower tube clamp 461 sleeved on the outer surface of the threaded tube 44. At this time, after the T-shaped threaded rod 463 is rotated to the upper surface of the upper tube clamp 462, the threaded knob 464 is rotated to make the threaded knob 464 contact the outer surface of the upper tube clamp 462, and a downward force is applied to make the lower tube clamp 461 and the upper tube clamp 462 tightly connected, thereby tightly clamping the threaded tube 44.
