Description

Technical Field

[0001] The present invention relates to the technical field of ship assembly and manufacturing, in particular to an impact-resistant assembly bracket. Background Art

[0002] During the shipbuilding process, different parts need to be assembled. Assembly is the process of combining qualified hull parts into components, sections, and final sections until the hull is assembled. Hull assembly is divided into hull structure pre-assembly welding and slipway assembly welding. Hull structure pre-assembly welding is further divided into component welding, section welding, and final assembly welding. The main equipment used in hull structure pre-assembly welding includes lifting, electric welding, gas cutting, and compressed air equipment. When pre-assembling the hull structure, ship assembly brackets are used to assist in assembly, and the assembly brackets will support the components during use.

[0003] For ships, their components are heavy, so when the ship components are placed on a conventional assembly bracket, there will be a certain impact on the assembly bracket. Under continuous work, the connection structure of the assembly bracket and its legs and other components will be subjected to a large load, thereby causing certain damage to the various components on the assembly bracket. As a result, the assembly bracket is prone to damage after repeated use, thereby reducing the service life of the assembly bracket. Summary of the Invention

[0004] In view of this, the present invention provides an impact-resistant assembly bracket to solve the problem in the prior art that due to the heavy weight of the components, when placed on the assembly bracket, the assembly bracket is subjected to a large impact, thereby reducing the service life of the assembly bracket.

[0005] The support rod is fixed on one of the base and the workbench, and the support rod is fixed on the other of the base and the workbench, and a sealing structure is provided on the support rod for sealing and sliding with the inner wall of the support rod, wherein a rod section with a support rod and a cavity section without a support rod are formed in the support rod, and a first elastic member for resisting the support rod so that the support rod has a tendency to move outward is also provided in the cavity section of the support rod, and hydraulic oil is also provided in the cavity section of the support rod, and an extension section is also provided on the support rod, and an extension space is provided in the extension section that is connected to the cavity in the cavity section, the sum of the extension space and the space in the cavity section remains unchanged while the space in the extension space and the space section is variable, and an oil hole for controlling the flow rate of hydraulic oil is provided between the cavity body of the extension section and the cavity section.

[0006] Furthermore, the extension section is arranged on the side wall of the cavity section, an oil separator is arranged between the cavity section and the extension section, the oil hole is arranged on the oil separator, and a piston plate is provided at the end of the extension section away from the support tube, which is sealed and slidably matched with the inner wall surface of the extension section.

[0007] Furthermore, the buffer structures are arranged in groups of two, the extension sections of the two buffer structures arranged in the group are aligned, and a second elastic member is provided between the piston plates in the two buffer structures to push the two piston plates to move away from each other.

[0008] Furthermore, a closed buffer cavity is formed between the two piston plates in the same group of buffer structures.

[0009] Furthermore, a fixture for clamping the workpiece to be processed is provided on the workbench, a protection mechanism is provided between the fixture and the workbench, and the protection mechanism includes a third elastic member provided between the fixture and the workbench.

[0010] Furthermore, a guide column is provided on one of the workbench and the fixture, and a guide hole that cooperates with the guide column is provided on the other one, and the third elastic member is a spring sleeved on the guide column.

[0011] Furthermore, a shock-absorbing pad is provided between the workbench and the fixture.

[0012] Furthermore, the workbench includes a platform plate and a mounting seat guided on the platform plate, the fixture is arranged on the mounting seat, and the workbench is also provided with a driving mechanism for driving the mounting seat to move horizontally relative to the platform plate.

[0013] Furthermore, a rolling wheel in contact with the platform plate is provided at the bottom of the mounting seat.

[0014] Furthermore, the base is provided with running wheels for driving the bracket to move.

[0015] The beneficial effects of the impact-resistant assembly bracket in the present invention are as follows: the impact-resistant assembly bracket in the present invention arranges the base and the workbench at intervals up and down, and provides a buffer structure between the two. Then, after a heavy component is placed on the workbench, a part of the impact will be buffered by the buffer structure, thereby reducing the impact on the bracket; specifically, by providing a nested support cylinder and a support rod, which are respectively connected to the base and the workbench, it is convenient for the base and the workbench to produce relative displacement; by providing a sealing structure on the support rod, it is convenient to maintain a closed space in the support cylinder during movement; by providing the first elastic member, it is convenient to elastically support the workbench, so that the workbench has the possibility of downward movement; because hydraulic oil is provided in the closed space, the support cylinder is used to release the oil. An extension section is also provided on the top. By setting an oil hole, the sum of the space in the extension space and the cavity section remains unchanged while the space in the extension space and the space section is variable. When a component to be processed is placed on the workbench, the workbench will be pressed down under the action of gravity, so that the workbench and the base are close to each other, the first elastic member is compressed and deformed, and the volume in the cavity section is reduced. In order to prevent the first elastic member from deforming too much, the hydraulic oil will flow into the extension space through the oil hole at this time. Since the oil hole can control the flow rate, the space in the cavity section will not change too quickly, making the descent and ascent of the workbench more gradual, thereby solving the problem in the prior art that due to the heavy weight of the component, the assembly bracket is subjected to a large impact when placed on the assembly bracket, thereby reducing the service life of the assembly bracket.

[0028] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0029] In embodiment 1 of the impact-resistant mounting bracket of the present invention:

[0030] like Figure 1 As shown, the impact-resistant assembly bracket in this embodiment includes a workbench and a base 1 spaced apart from each other. The workbench is located at the top, and the base 1 is used to support the ground. A buffer structure 33 is provided between the workbench and the base 1 to cushion the impact on the workbench. A clamp is provided on the workbench to clamp and secure the workpiece. Two sets of bases 1 are provided, one on each side of the bottom of the workbench. The bases 1 are equipped with running wheels 11, which can be used to move the assembly bracket to a specific position for convenient use.

[0031] like Figure 1 and Figure 4As shown, specifically, the buffer structure 33 includes a support tube 331 and a support rod 332 arranged between the base 1 and the workbench. One end of the support tube 331 is closed and the other end is open. The support tube 331 with an open end accommodates the support rod 332 nested therewith, and the support rod 332 is exposed from the support tube 331. In this embodiment, the end of the support rod 332 away from the support tube 331 is fixedly connected to the workbench, and the support tube 331 is fixedly connected to the base 1. The support rod 332 can slide in the support tube 331, that is, the base 1 and the workbench can move relative to each other. In addition, the support rod 332 is also provided with a sealing structure for sealing contact with the inner wall surface of the support tube 331. The support rod 332 divides the support tube 331 into two parts within the support tube 331, one of which is a rod section with the support rod 332, and the other is a cavity section without the support rod 332. It is worth noting that since the support rod 332 is movable relative to the support tube 331, the lengths of the rod section and the cavity section will also change accordingly. A first elastic member is provided in the cavity section for supporting the support rod 332 so that the support rod 332 has a tendency to move outward. In this embodiment, the first elastic member is a first spring 333. When a heavy component is placed on the workbench, an instantaneous impact will act on the workbench, and the impact will be transmitted to the first spring 333 through the support rod 332, forcing the first spring 333 to produce compression deformation. Of course, in other embodiments, the positions of the support rod and the support tube can also be swapped, so that the support rod is connected to the base and the support tube is connected to the workbench.

[0032] The characteristic of a spring is that its elastic force increases as the compression stroke increases. Therefore, a large deformation may occur at the moment of impact, which is not conducive to the placement of components. Therefore, in this embodiment, hydraulic oil is also provided in the cavity section, and an extension section 334 is provided on the outer wall of the support cylinder 331 located in the cavity section. An oil separator is provided between the cavity section and the extension section 334. The oil separator is provided with an oil hole 337. The oil hole 337 is a small hole that limits the speed at which the hydraulic oil flows. A piston plate 335 is also provided at the end of the extension section 334 away from the support cylinder 331, which is sealed and slidably matched with the inner wall surface of the extension section 334, thereby allowing the space within the extension section 334 to change. Under the action of the support rod 332, the volume of the cavity section will also change, thereby allowing the hydraulic oil to flow from one chamber to another through the oil hole 337. The limited size of oil hole 337 limits the flow rate, further affecting the change in volume within the cavity section and extension section 334, slowing down the change rate of the cavity section and extension section 334. Specifically, when a heavy component is placed on the workbench, the first spring 333 is compressed, reducing the volume within the cavity section. Hydraulic oil then enters the extension section 334 through oil hole 337. However, the small size of oil hole 337 limits the flow rate of the hydraulic oil. Due to the incompressibility of hydraulic oil, the change in the cavity section's volume is equal to the volume of the hydraulic oil flowing, thus slowing down the change rate of the cavity section and effectively absorbing and dissipating pressure from the workbench.

[0033] The buffer structures 33 are arranged in pairs. In this embodiment, two groups of buffer structures 33 are provided, with two buffer structures 33 in each group. The extensions 334 of the two buffer structures 33 in each group are aligned and sealed together, forming a sealed buffer chamber between the two piston plates 335 within the two buffer structures 33. Within this buffer chamber is a second elastic member, in this embodiment a second spring 336, which propels the two piston plates 335 away from each other. Two second springs 336 are provided, one for each piston plate 335, with a mounting bracket for mounting the second springs 336 located between the two second springs 336. Due to the sealed buffer chamber, the piston plates 335 must compress the air within the chamber during movement, increasing resistance to movement. This resistance is further increased by the action of the second springs 336, slowing the movement of the piston plates 335 and providing greater resistance to dissipating and absorbing the initial impact. That is, through the arrangement of the above structure, when the workbench is impacted, the impact is transferred to the chamber structure where the hydraulic oil is located, and the workbench is prevented from swinging up and down by slowly deforming the volume of the chamber. Of course, in other embodiments, each buffer structure can also be provided separately.

[0034] like Figure 2 and Figure 3As shown, the workbench is equipped with two fixtures for clamping the workpiece to be processed: a positioning fixture 22 placed above the workbench and a fixing fixture 23 hingedly mounted on the side of the workbench. A protective structure is also provided between the positioning fixture 22 and the workbench to protect against impact. The positioning fixture 22 and the fixing fixture 23 can clamp and secure the workpiece to be processed.

[0035] The workbench includes a platform plate 26 fixedly connected to a support rod 332 and a mounting base 31 located on the platform plate 26 for mounting the positioning fixture 22. During use, the position of the fixing fixture 23 needs to be moved to different positions according to different components, so the position of the mounting base 31 relative to the platform plate 26 is adjustable. Specifically, in this embodiment, the workbench is also provided with a driving mechanism, which includes a motor 24 and a lead screw disposed on the output shaft of the motor 24. The mounting base 31 is provided with a threaded hole that cooperates with the lead screw. The lead screw and the mounting base 31 also constitute a lead screw nut mechanism. When the motor 24 rotates, the motor 24 can drive the mounting base 31 to move on the platform plate 26. In order to reduce frictional resistance during movement, a rolling wheel 325 is also provided at the bottom of the mounting base 31. The rolling wheel 325 converts sliding friction into rolling friction, facilitating better movement of the mounting base 31. In addition, to further limit the movement direction of the mounting base 31, a rectangular guide frame 21 is fixedly provided on the platform plate 26, and the motor 24 is fixedly mounted on the guide frame 21.

[0036] The positioning fixture 22 is arranged on the mounting seat 31. In order to facilitate installation, a fixture base plate 322 is provided below the positioning fixture 22. In order to protect the positioning fixture 22, a guide hole 321 is provided on the mounting seat 31. A guide column that cooperates with the guide hole 321 is provided at the bottom of the fixture base plate 322 of the positioning fixture 22. A third elastic member is also sleeved on the guide column. The third elastic member is a spring, which makes it convenient for the positioning fixture 22 to move up and down relative to the workbench when it is subjected to force, and to consume part of the impact through the third elastic member. In addition, a shock-absorbing pad 326 is also provided between the fixture base plate 322 and the mounting seat 31. Of course, in other embodiments, a guide hole 321 can also be provided on the fixture base plate 322, and a guide column can be provided on the mounting seat 31, so that the two will not be disengaged during movement. Alternatively, in other embodiments, the third elastic member can also be an elastic washer.

[0037] During use, the part to be processed is first placed on the positioning fixture 22, at which point it will cause a certain impact on the assembly bracket. This impact first acts on the third spring 324 and the shock pad 326, which absorb some of the impact. The impact is then applied to the buffer structure 33 along the workbench. The support rod 332 on the buffer structure 33 moves downward, compressing the first spring 333, which absorbs some of the impact. Simultaneously, the support rod 332 acts on the hydraulic oil, causing it to move from the cavity section toward the extension section 334, thereby driving the piston plate 335 outward. This movement overcomes the elastic force of the second spring 336, which absorbs some of the impact. Due to the limited diameter of the oil hole 337, not much hydraulic oil can pass through at the moment of contact. Therefore, the cavity and the hydraulic oil absorb some of the impact, ultimately significantly reducing the impact on the fixture and the workbench.

[0038] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
