Description

TECHNICAL FIELD

[0001] The utility model relates to shipbuilding technical field, especially a kind of self-adapting alignment equipment for ship section closing. BACKGROUND

[0002] Ship section closing is the key technology of shipbuilding, and its core task is to accurately splice prefabricated sections into a complete ship body. The traditional alignment device mainly relies on manual operation and simple mechanical tools, which has the following technical bottlenecks:

[0003] 1. The existing device uses independent adjustment mechanism (such as single screw lift or hydraulic jacking device), which can only realize single-axis translation or single-angle compensation, and cannot handle complex deviations in three-dimensional space simultaneously. For ship sections with complex curvature, traditional devices are difficult to adapt, and frequent tool replacement or manual intervention is required.

[0004] 2. The device fixed by bolts or pins is prone to retreat due to ship vibration or external impact after adjustment, and needs to be frequently checked. It lacks automatic locking function, increasing the complexity and time cost of operation.

[0005] 3. Multi-axis adjustment requires the cooperation of multiple workers, with complicated operation steps and long time consumption. The existing device does not integrate limiting and buffering functions, which may cause mechanical damage due to overtravel sliding or overload.

[0006] Therefore, the inventor has made unremitting research and improvement, and finally produced the self-adapting alignment equipment for ship section closing. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to provide a self-adapting alignment equipment for ship section closing, which can simultaneously realize horizontal translation, vertical lifting and pitch angle adjustment, and fix the adjusted position through mechanical locking mechanism, with the characteristics of simple structure, convenient operation and reliable locking.

[0008] The above technical purpose of the utility model is realized by the following technical scheme: a simple alignment device for ship section closing, comprising a base, a translation adjustment mechanism, an angle adjustment mechanism and a locking mechanism. The base is provided with adjustable supporting feet at the bottom. The translation adjustment mechanism is installed above the base and comprises a horizontal sliding table and a vertical sliding table. The horizontal sliding table is connected with the base through a guide rail. The vertical sliding table is connected with the horizontal sliding table through a lead screw. The angle adjustment mechanism is arranged at the top of the vertical sliding table and comprises a hinged support and an adjusting screw. The hinged support is hinged with the vertical sliding table. One end of the adjusting screw is threadedly connected with the side surface of the hinged support. The locking mechanism comprises locking bolts arranged on the horizontal sliding table and the vertical sliding table. The end of the locking bolt abuts against the nut of the guide rail and the lead screw.

[0009] By adopting the technical scheme, the horizontal sliding table and the vertical sliding table realize X / Y axis translation, the hinged support and the adjusting screw realize pitch angle compensation, and the locking bolt provides reliable mechanical locking function, thereby solving the problems of single function and poor locking reliability of the traditional device.

[0010] Further, the thread of the screw lifting rod is a self-locking trapezoidal thread, the pitch is 4mm, and the thread outer diameter is gap-fitted with the mounting hole of the base.

[0011] By adopting the technical scheme, the self-locking trapezoidal thread prevents the base from loosening in a vibrating environment, and the pitch accuracy matches the millimeter-level adjustment requirement of the ship section closing.

[0012] Further, the guide rail of the horizontal sliding table is a double-V type guide rail, and the two sides of the guide rail are provided with scale marks.

[0013] By adopting the technical scheme, the double-V type guide rail provides stable sliding support, and the scale marks are convenient for an operator to intuitively read the adjustment amount.

[0014] Further, the axis of the adjusting screw is perpendicular to the hinged axis of the hinged support, and the bottom of the adjusting screw is provided with a hand wheel.

[0015] By adopting the technical scheme, the hand wheel provides greater operating torque, and it is convenient for a single person to complete angle adjustment.

[0016] Further, the end of the locking bolt is provided with a rubber gasket, and the rubber gasket is in contact with the surfaces of the guide rail and the nut.

[0017] By adopting the technical scheme, the rubber gasket increases friction, prevents the locking bolt from loosening due to vibration, and protects the surfaces of the guide rail and the nut.

[0018] Further, the guide rail of the horizontal sliding table is provided with limit blocks at both ends, the limit blocks are fixedly connected with the base through bolts, and the inner side of the limit block is provided with a buffer pad.

[0019] By adopting the technical scheme, the limit blocks prevent the sliding table from sliding beyond the range, the buffer pad absorbs impact force, and the service life of the device is prolonged.

[0020] Further, the bottom of the lead screw of the vertical sliding table is provided with a hand crank, the axis of the hand crank is collinear with the shaft of the lead screw, and the surface of the hand crank is provided with anti-skid lines.

[0021] By adopting the technical scheme, the hand crank provides greater operating torque, and the anti-skid lines ensure stable operation in a humid environment. BRIEF DESCRIPTION OF DRAWINGS
