Description

Technical Field

[0001] The utility model belongs to the technical field of welding devices for garage frame structures, and particularly relates to a welding device for garage frame structures. Background Art

[0002] A three-dimensional garage is a mechanical or mechanical equipment system assembled by using a steel structure as the main frame, in cooperation with a lifting and traversing device and a control system, and is used for storing and retrieving vehicles in the largest quantity. The welding device for the garage frame structure is mainly used for welding the main frame structure of the three-dimensional garage.

[0003] For the existing garage frame welding device, due to the complex main frame structure and large individual size of the three-dimensional garage, and a large number of welds, when clamping the frame, a placement plate and a quick clamp are used for fixing. When the placement plate clamps an uneven frame, it is not easy to level. The uneven surface causes the clamp to be unable to apply pressure evenly, making it difficult to fix the frame; the placement plate will block the position to be welded, so it is necessary to clamp repeatedly, affecting the work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding device for a garage frame structure, which can avoid blocking the welding area of the frame to be welded.

[0005] The welding device for the garage frame structure includes a device base horizontally arranged for fixing the frame. A welding robotic arm is installed on one side of the device base. Two rotating blocks are symmetrically arranged at left and right intervals on the device base. The rotating blocks can all rotate in the front-back direction. From right to left, they are the first rotating block and the second rotating block in sequence;

[0006] Two first fixing blocks for clamping the frame and distributed vertically are installed at the left end of the first rotating block. The first fixing blocks can move up and down along the first rotating block. The right end of the first rotating block is connected with a bearing that can rotate back and forth. The bearing is connected with a bearing seat. The bottom of the bearing seat is installed with a slide rail that is slidably matched with it left and right. The slide rail is installed on the device base;

[0007] Two second fixing blocks for clamping the frame and distributed vertically are installed at the right end of the second rotating block. The second fixing blocks can move up and down along the second rotating block. The left end of the second rotating block is connected with a driving component for driving it to rotate back and forth.

[0008] The welding robotic arm is used to weld the frame fixed to the inner sides of two rotating blocks. By means of one upper and one lower first fixing block sliding up and down along the first rotating block, the right end of the frame is clamped towards the middle. By means of one upper and one lower second fixing block moving up and down along the second rotating block, the left end of the frame is clamped towards the middle. The bearing block slides left and right along the slide rail to adjust the distance between the first fixing block and the second fixing block, so as to adapt to the fixing of frames of different lengths. The bearing rotates within the bearing block, which can drive the first rotating block to rotate. The driving assembly drives the second rotating block to rotate, driving the first rotating block to rotate, and realizing the adjustment of different welding angles during the frame welding process. The clamping and rotation at both left and right ends can avoid blocking the welding area of the frame to be welded.

[0009] Further, a slider that is in left-right sliding fit with the slide rail is installed on the slide rail. The slider is connected to the bearing block. A first hydraulic cylinder is installed on the device base on the right side of the slide rail. The piston rod of the first hydraulic cylinder is connected to the slider and can drive the slider to move left and right.

[0010] The left-right movement of the piston rod of the first hydraulic cylinder drives the slider to move left and right along the slide rail.

[0011] Further, vertical convex blocks are fixed to the front and rear sides of the left end of the first rotating block and the front and rear sides of the right end of the second rotating block. Clamping blocks that are in up-down sliding fit with the convex blocks are fixed to the first fixing block and the second fixing block. Adjusting assemblies for driving the first fixing block and the second fixing block to move up and down are installed on the first rotating block and the second rotating block respectively.

[0012] The convex blocks and the clamping blocks in up-down sliding fit drive the first fixing block to move up and down along the first rotating block and drive the second fixing block to slide up and down along the second rotating block under the adjustment of the adjusting assembly.

[0013] Further, through grooves with an up-down communicating groove structure are formed on the left side wall of the first rotating block and the right side wall of the second rotating block.

[0014] The adjusting assembly includes a second hydraulic cylinder. The cylinder body of the second hydraulic cylinder is installed in the through groove. The piston rods of the second hydraulic cylinder are respectively connected to the corresponding first fixing block and second fixing block and can drive the first fixing block and the second fixing block to move up and down.

[0015] Installing the cylinder body of the second hydraulic cylinder in the through groove facilitates the piston rod of the second hydraulic cylinder to drive the first fixing block and the second fixing block to move up and down during the up-down movement.

[0016] Further, connection blocks that can move up and down in the through groove are fixed to the connection parts of the piston rod of the second hydraulic cylinder with the first fixing block and the second fixing block. The connection blocks are respectively connected to the piston rod of the corresponding second hydraulic cylinder.

[0017] The piston rod of the second hydraulic cylinder within the first rotating block is connected to the connecting block on the first fixed block, and the piston rod of the second hydraulic cylinder within the second rotating block is connected to the connecting block on the second fixed block, facilitating the installation of the second hydraulic cylinder.

[0018] Furthermore, the driving assembly includes a motor, and the power output end of the motor is connected to the second rotating block.

[0019] The motor drives the second rotating block to rotate, saving time and effort.

[0020] Furthermore, a mounting plate is fixed on the device base between the second rotating block and the motor, and the rotating shaft of the motor independently passes through the mounting plate and then is connected to the second rotating block.

[0021] The mounting plate can protect the motor.

[0022] Furthermore, a robotic arm mounting base is provided at the bottom of the welding robotic arm.

[0023] The robotic arm mounting base facilitates the installation of the welding robotic arm.

[0024] Furthermore, a rotating shaft is fixed to the right end of the first rotating block, and the right end of the rotating shaft is connected to the bearing within the bearing housing.

[0025] The rotating shaft facilitates being inserted into the bearing.

[0026] Furthermore, grooves are formed on the walls of the first fixed block and the second fixed block facing the inner side of the clamping portion.

[0027] The grooves facilitate the limiting of the clamping portion.

[0028] Compared with the prior art, the present utility model has the following beneficial effects:

[0029] The welding robotic arm is used to weld the frame fixed inside the two rotating blocks. By means of one upper and one lower first fixed block sliding up and down along the first rotating block to clamp the right end of the frame towards the middle, and one upper and one lower second fixed block moving up and down along the second rotating block to clamp the left end of the frame towards the middle, the bearing housing slides left and right along the slide rail to adjust the distance between the first fixed block and the second fixed block, so as to adapt to the fixation of frames of different lengths; the bearing rotates within the bearing housing, which can drive the first rotating block to rotate, and the driving assembly drives the second rotating block to rotate, driving the first rotating block to rotate, realizing the adjustment of different welding angles during the frame welding process. The clamping and rotation at both left and right ends can avoid blocking the welding area of the frame to be welded. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Manufacture two second fixing blocks 10; the second fixing blocks 10 have the same structure as the first fixing block 9 and are manufactured by the same method.

[0060] Manufacture one slider 15; as Figure 2 and Figure 6 shown, the main body of the slider 15 is a rectangular block structure, and two "T"-shaped sliding grooves that are symmetrically arranged front and back in the direction as Figure 2 shown are formed at the bottom of the slider 15.

[0061] Step 2: Assembly

[0062] As Figure 1 shown, horizontally place the robotic arm mounting base 1 and the device base 3, and weld the robotic arm 2 to the robotic arm mounting base 1; install the slide rail 5 on the top surface of the right side of the device base 3, and fit the slider 15 onto the slide rail 5; as Figure 2 shown, install a bearing seat 6 on the top surface of the slider 15, and pass a rotating shaft 7 through the bearing in the bearing seat 6; fix the first rotating block 8 at the left end of the rotating shaft 7, and the through groove 16 of the first rotating block 8 is located on the left side wall and is vertically connected, and two second hydraulic cylinders 14 that are symmetrically arranged up and down are installed in the through groove 16; fit the first fixing block 9 onto the first rotating block 8, and make the clamping block 19 and the convex block 20 in vertical sliding fit; connect the connecting block 18 to the piston rod of the corresponding second hydraulic cylinder 14;

[0063] As Figure 1 shown, install the cylinder body of the first hydraulic cylinder 4 at the top of the right end of the device base 3, on the device base 3 on the right side of the two slide rails 5; as Figure 2 shown, fix the piston rod of the first hydraulic cylinder 4 to the slider 15;

[0064] As Figure 2 shown, install the motor 13 on the top surface of the left end of the device base 3, and pass the right end of the rotating shaft of the motor 13 through the through hole of the mounting plate 12 and then fix it to the second rotating block 11; install the second fixing block 10 and the second hydraulic cylinder 14 on the second rotating block 11, and the cooperation relationship is the same as that between the first rotating block 8 and the first fixing block 9, and they are installed by the same method.

[0065] The usage instructions are as follows:

[0066] During use, as Figure 7 shown, first, according to the length of the garage frame structure, start the first hydraulic cylinder 4 to make the slider 15 slide along the slide rail 5, thereby adjusting the distance between the first fixing block 9 and the second fixing block 10; the first fixing block 9 and the second fixing block 10 are opened or closed in the clamping area through the second hydraulic cylinder 14 to clamp the garage frame structure;

[0067] The welding robot arm 2 welds the front surface of the garage frame structure. After the welding of this surface is completed, start the motor 13 to drive the second rotating block 11 to rotate. With the cooperation of the bearing seat 6, the first rotating block 8 and the second rotating block 11 rotate simultaneously, thereby driving the garage frame structure to turn over or adjust the angle, and the welding robot arm 2 welds other angles of the garage frame structure; the self-locking function of the bearing seat 6 can prevent the first rotating block 8 from shifting due to gravity after the garage frame structure is unloaded.

[0068] In the above solution, by clamping and fixing both ends of the garage frame structure, the occlusion of the garage frame structure is minimized to avoid occlusion of the welding position, reduce the number of clamping operations, and improve work efficiency; both the first fixing block 9 and the second fixing block 10 are centrally clamped through the second hydraulic cylinder 14, so that when the sizes of both ends of the garage frame structure are inconsistent, horizontal clamping can still be performed, with good stability and reduced deformation or displacement caused by gravity.
