Description

Technical Field

[0001] The utility model belongs to the technical field of hot riveting welding equipment, and particularly relates to a hot riveting welding device for ship steel structure processing. Background Art

[0002] In the process of ship steel structure processing and manufacturing, hot riveting welding is one of the key processes to ensure the connection strength and stability of the structure. At present, desktop hot riveting welding devices are widely used in the field of ship steel structure processing due to their relatively simple operation and low cost. However, the existing desktop hot riveting welding devices have obvious defects. The compression molding positions during welding are mostly fixedly set, or only have limited longitudinal adjustment functions, and it is difficult to achieve flexible lateral adjustment.

[0003] In actual processing, when a hot riveting weld is completed at one location, if the welding position of the plate needs to be adjusted, the operator often needs to lift the plate and reposition it, which is a cumbersome and inefficient process. At the same time, frequent movement of the plate is likely to cause positioning deviation and affect the welding quality.

[0004] In addition, the plates of ship steel structure parts are generally hot riveted and welded from both sides respectively to ensure the effect of the weld joints of the plates. When welding the position on the other side is required, due to the inability to conveniently adjust the compression molding position laterally, the operator often needs to flip and adjust the plate surface to align the other side with the welding position, which is very inconvenient to operate and reduces the production efficiency. Therefore, another hot riveting welding device for ship steel structure processing is provided to solve the above technical problems. Summary of the Utility Model

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a hot riveting welding device for ship steel structure processing, which is used to solve the problems in the prior art that the compression molding positions during welding of the desktop hot riveting welding device are mostly fixedly set, it is difficult to achieve flexible lateral adjustment, resulting in cumbersome adjustment of the welding position of the plate, and the operation is inconvenient and the production efficiency is low when welding the other side of the plate due to the inability to conveniently adjust the compression molding position laterally.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A hot riveting and welding device for ship steel structure processing, comprising a chassis. At the four corners of the upper surface of the chassis, connecting columns are fixedly installed. Side support plates are fixedly installed between two adjacent front and rear connecting columns. A top frame is fixedly installed above the chassis, and the top frame is fixedly connected to the connecting columns. Hydraulic telescopic columns and T-shaped load blocks are adjustably installed in both the chassis and the top frame. A upper plastic pressing head is fixedly installed on the lower surface of the hydraulic telescopic column, and a telescopic stress plastic head is fixedly installed on the upper surface of the T-shaped load block. The telescopic stress plastic head is directly below the upper plastic pressing head. A alignment and synchronous position adjustment device for driving the hydraulic telescopic column and the telescopic stress plastic head to synchronously adjust their positions is installed between the chassis and the top frame.

[0008] In the above technical solution, the telescopic stress plastic head includes a hollow sleeve fixedly installed on the upper surface of the T-shaped load block. A lower plastic pressing head is slidably installed in the hollow sleeve. A spring is fixedly installed between the lower surface of the lower plastic pressing head and the upper surface of the T-shaped load block.

[0009] In the above technical solution, three positioning holes are circumferentially and equidistantly formed on the outer surface of the lower plastic pressing head. Three electromagnetic pin columns are circumferentially and equidistantly fixedly installed on the outer surface of the hollow sleeve. The telescopic end of the electromagnetic pin column penetrates through the hollow sleeve and is inserted and installed in the corresponding positioning hole. The three electromagnetic pin columns are electrically connected to an external controller.

[0010] In the above technical solution, two sliding grooves are formed on the outer surface of the hollow sleeve. Two sliding blocks are fixedly installed on the outer surface of the lower plastic pressing head, and the sliding blocks are slidably installed in the corresponding sliding grooves.

[0011] In the above technical solution, two sliding channels are penetrated and formed on the upper surfaces of both the top frame and the chassis. A U-shaped load block is slidably installed between the two sliding channels of the top frame. The hydraulic telescopic column is fixedly installed through the front end of the U-shaped load block, and the T-shaped load block is slidably installed in the sliding channel at the front end of the chassis;

[0012] The alignment and synchronous position adjustment device includes two threaded rods. The two threaded rods are respectively rotatably installed on the lower surface of the chassis and the upper surface of the top frame. The rear end of the U-shaped load block is screwed and installed on the outer surface of the upper threaded rod, and the T-shaped load block is screwed and installed on the outer surface of the lower threaded rod. Chain wheels are sleeved on the right ends of the threaded rods, a transmission chain is installed between the two chain wheels, and a hand wheel is fixedly installed on the right end of the upper threaded rod.

[0013] The hot riveting and welding device for ship steel structure processing of the present utility model, compared with the prior art, has the beneficial effects as follows:

[0014] The utility model installs adjustable hydraulic telescopic columns and T-shaped load blocks in the top frame and the bottom frame respectively. The upper compression head is installed on the lower surface of the hydraulic telescopic column, and the telescopic stress head containing the positioning mechanism is installed on the upper surface of the T-shaped load block. The hydraulic telescopic column is installed at the front end of the U-shaped load block, and the alignment and synchronous adjustment device is set. The alignment and synchronous adjustment device can move the U-shaped load block and the T-shaped load block at the same time, so that the upper compression head and the telescopic stress head are adjusted synchronously to meet the requirements of different transverse welding positions of the plate, solving the problem that the existing device is difficult to achieve flexible transverse adjustment, and improving the production efficiency;

[0015] In addition, by setting a telescopic stress head with three electromagnetic pin columns, during welding, the three electromagnetic pin columns can be used to position the lower compression head to ensure that the hot rivet is compressed into a specific arc. After welding, the electromagnetic pin columns contract, and under the action of the spring, the lower compression head can be pushed and moved downward by the solder joint, so that the solder joint can smoothly disengage from the arc-shaped groove, facilitating the movement and adjustment of the plate for the welding position without lifting the plate, and the operation is more convenient.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The front, rear, left, right, top and bottom in this embodiment are described with Figure 1 as the reference plane. Please refer to Figures 1 - 6 , the present invention provides a technical solution:

[0025] A hot riveting welding device for ship steel structure processing, including a chassis 1 with two sliding grooves penetrating through the upper surface. At the four corners of the upper surface of the chassis 1, connecting columns 2 are fixedly installed. Side support plates 21 are fixedly installed between two adjacent front and rear connecting columns 2. The shapes of the two side support plates 21 are as Figure 1 shown, and the two are used to lift the plate to be welded. When the plate is placed on the side support plates 21, the left and right surfaces of the plate are attached to the two side support plates 21 on both sides. A top frame 3 is fixedly installed above the chassis 1. The top frame 3 is fixedly connected to the connecting column 2. Hydraulic telescopic columns 4 and T-shaped carrier blocks 5 capable of adjusting positions are respectively installed in the top frame 3 and the chassis 1. The T-shaped carrier block 5 is slidably installed in the through sliding groove at the front end of the chassis 1. A upper plastic pressing head 41 with an arc-shaped groove on the lower surface is fixedly installed on the lower surface of the hydraulic telescopic column 4. A telescopic stress plastic head 6 containing a positioning mechanism is fixedly installed on the upper surface of the T-shaped carrier block 5. The telescopic stress plastic head 6 is located directly below the upper plastic pressing head 41, and an arc-shaped groove is provided at the top of the telescopic stress plastic head 6. An alignment and synchronization adjustment device 7 for driving the hydraulic telescopic column 4 and the telescopic stress plastic head 6 to synchronously adjust positions left and right is installed between the chassis 1 and the top frame 3.

[0026] When using this device, first fix the two plates to be welded through external clamps, align and fix the welding holes for hot riveting welding. Then, place the plates on the two side support plates 21. Manually adjust the position of the plates to align the hot rivet holes on the plates with the telescopic stress plastic head 6, and then penetrate the hot rivets. Next, the hydraulic telescopic column 4 extends, driving the upper plastic pressing head 41 to move downward, cooperating with the telescopic stress plastic head 6 to extrude and shape the hot rivets, completing the hot riveting welding operation. After welding, the hydraulic telescopic column 4 drives the upper plastic pressing head 41 to move upward and reset, and the telescopic stress plastic head 6 releases the internal positioning mechanism. Manually push the plate backward, and utilize the stress expansion and contraction characteristics of the telescopic stress plastic head 6 to make the arc-shaped weld spot slide out of the arc-shaped groove of the telescopic stress plastic head 6, and align the next hot rivet hole of the plate with the position below the upper plastic pressing head 41 for subsequent riveting welding work.

[0027] It should be noted that the telescopic stress plastic head 6 includes a hollow sleeve 61 fixedly installed on the upper surface of the T-shaped load block 5. A downward pressure plastic head 62 is vertically and slidably installed in the hollow sleeve 61. The arc-shaped groove at the top of the telescopic stress plastic head 6 is arranged on the upper surface of the downward pressure plastic head 62. A spring 63 is fixedly installed between the lower surface of the downward pressure plastic head 62 and the upper surface of the T-shaped load block 5. Three positioning holes 621 are circumferentially and equidistantly arranged on the outer surface of the downward pressure plastic head 62. Three electromagnetic pin columns 64 are circumferentially and equidistantly fixedly installed on the outer surface of the hollow sleeve 61. The telescopic end of the electromagnetic pin column 64 penetrates through the hollow sleeve 61 and is inserted into the corresponding positioning hole 621 to position the downward pressure plastic head 62 from three directions. When the telescopic stress plastic head 6 cooperates with the upper pressure plastic head 41, the downward pressure plastic head 62 is stressed under the positioning of the three electromagnetic pin columns 64 to ensure that the hot rivet can be compressed into a specific arc shape. After the hot riveting is completed, the electromagnetic pin column 64 is contracted, and its telescopic end is withdrawn from the positioning hole 621 to release the fixation of the downward pressure plastic head 62. When the plate moves while being attached to the side support plate 21, under the action of the spring 63, the downward pressure plastic head 62 can be pushed by the solder joint and move downward and contract into the hollow sleeve 61, so that the solder joint can smoothly disengage from the arc-shaped groove on the downward pressure plastic head 62 to ensure the normal movement of the plate. The advantage of this design is that when moving the plate, it is not necessary to lift the plate, and only by pushing it backward, the solder joint can be pushed away from the arc-shaped groove on the downward pressure plastic head 62, which can make the adjustment of the welding position of the plate more convenient.

[0028] The three electromagnetic pin columns 64 are electrically connected to an external controller;

[0029] Regarding the synchronous control and telescoping of the three electromagnetic pin columns 64, the principle is as follows: The three electromagnetic pin columns 64 are connected to a unified drive circuit, and this drive circuit adopts a parallel connection method, so that the voltage at both ends of each electromagnetic pin column 64 remains the same. By sending a specific electrical signal through the external controller, this electrical signal is amplified and distributed and then acts on the three electromagnetic pin columns 64 simultaneously, thereby achieving the effect of synchronous telescoping. During the control process, the external controller can precisely control the telescoping time and force of the electromagnetic pin columns 64 to meet different working requirements.

[0030] Two sliding grooves 611 are arranged on the outer surface of the hollow sleeve 61. Two sliding blocks 622 are fixedly installed on the outer surface of the downward pressure plastic head 62. The sliding blocks 622 are slidably installed in the corresponding sliding grooves 611. Through the cooperation of the sliding blocks 622 and the sliding grooves 611, the downward pressure plastic head 62 can slide vertically, ensuring that after self-resetting, the positioning hole 621 can correspond to the position of the electromagnetic pin column 64 to ensure the accuracy of positioning.

[0031] The upper surface of the top frame 3 is also provided with two sliding grooves penetrating therethrough. A U-shaped carrier block 31 is slidably installed between the two sliding grooves of the top frame 3. The hydraulic telescopic column 4 is fixedly installed through the front end of the U-shaped carrier block 31. Two fixing plates are symmetrically and fixedly installed on the upper surface of the top frame 3 and the lower surface of the bottom frame 1 respectively.

[0032] The alignment and synchronous position adjustment device 7 includes two threaded rods 71. The two threaded rods 71 are respectively rotated through bearings between two adjacent fixing plates on the left and right. The rear end of the U-shaped carrier block 31 is screwed and installed on the outer surface of the upper threaded rod 71. The T-shaped carrier block 5 is screwed and installed on the outer surface of the lower threaded rod 71. Sprockets 72 are respectively sleeved on the right ends of the threaded rods 71. A transmission chain 73 is sleeved between the two sprockets 72. And a handwheel 74 is fixedly installed by welding on the right end of the upper threaded rod 71.

[0033] When it is necessary to perform left-right synchronous position adjustment on the upper compression head 41 located above and the lower compression head 62 located below, only need to manually rotate the handwheel 74. Through the cooperation of the sprocket 72 and the transmission chain 73, the two threaded rods 71 are synchronously driven to rotate, and then the U-shaped carrier block 31 and the T-shaped carrier block 5 are synchronously driven to slide left or right, so as to adjust the positions of the hydraulic telescopic column 4 and the telescopic stress plastic head 6, and finally complete the synchronous adjustment of the upper compression head 41 and the lower compression head 62 to meet the adjustment requirements of different welding positions of the plate in the transverse direction. During the actual welding operation process, there is no need to adjust the welding surface of the welding material by turning over, and the welding position can be adjusted transversely, which is convenient and fast to use and can improve the welding efficiency.
