An arm beam tailor-welding tool

Abstract

This utility model relates to a welding fixture for arm beams, including an operating table and two placement plates set on the top of the operating table. The arm beam to be welded is placed in the storage slot on the top of the placement plates. First, two first cylinders are activated, which drive two abutment seats to retract, pressing the arm beam against the abutment seats. The arm beam is then fixed between the abutment seats and the abutment protrusions. Simultaneously, two second cylinders are activated, which push push rods to rotate at the connecting seat, pressing down the adhesive layer seat at the top of the push rod onto the top of the arm beam, providing vertical pressure and fixation for the arm beam. When the first cylinder pushes the abutment seats to move, the guide slider at the bottom of the abutment seats slides in the guide groove, providing guidance for the movement of the abutment seats. When welding a bent arm beam, the placement plates can be rotated to rotate and adjust the column within the operating table. After adjusting to the appropriate position, a third cylinder is activated to move the bonding seat upward, causing the top of the bonding seat to press against the operating table, thus limiting the position of the column.

Description

Technical Field

[0001] This utility model relates to the technical field of boom beam welding equipment, specifically a boom beam welding fixture. Background Technology

[0002] The boom beam consists of multiple parts, and each part needs to be fixed during the welding process; otherwise, the quality of the boom beam after welding will be affected. In the existing technology, the fixation of the boom beam in one direction is not perfect, which makes the boom beam prone to shaking during the welding process. It is impossible to achieve multi-directional fixation and protection of the boom beam. At the same time, some boom beams are curved, and the equipment for fixing the boom beam cannot be adjusted according to the angle, making it difficult to adapt to different types of boom beams for splicing and welding.

[0003] For example, the authorized patent document CN201820662925.6 discloses a rocker arm beam welding fixture, which includes a turntable and a rotating screw positioning mechanism. A base plate is connected to the top of the turntable, and pads are fixed to the left and right sides of the middle of the base plate. A nut seat is installed on the right side of each pad, and a screw is connected to the top of the nut seat. A pressure plate is fixed to the top of the screw, and a welding clamp is installed on the top of the pressure plate. Limit block supports are connected to the left and right sides of the upper end of the base plate, and limit blocks are installed on the top of each limit block support. A baffle is fixed to the right side of the pressure plate, and a movable nut seat is installed on the left side of the base plate. This rocker arm beam welding fixture, by loosening the trapezoidal nut seat, extends and fixes the trapezoidal screw and the tightening sleeve on the support forward, thus preparing the robot for rotating welding. Then, by tightening the trapezoidal nut seat, the trapezoidal screw and the tightening sleeve are pushed to fix the robot, thereby shortening working time and improving work efficiency.

[0004] The aforementioned patent has the problem that the fixation of the boom beam in a single direction is not perfect, which makes the boom beam prone to shaking during the welding process and cannot achieve multi-directional fixation and protection of the boom beam. Therefore, we need to provide a boom beam welding fixture. Utility Model Content

[0026] Please see Figure 1-5This utility model provides a technical solution: a welding fixture for arm beams, comprising:

[0027] Operating table 1, and two placement boards 2 set on top of operating table 1;

[0028] The top of each of the two placement plates 2 is fixedly installed with a placement seat 3. The top of each of the two placement seats 3 is provided with a storage slot 4 for placing the arm beam. One side of each of the two storage slots 4 is provided with a side abutting protrusion 5 for abutting the placement seat 3. The top of each of the two placement seats 3 is provided with a limiting abutting mechanism 6 for clamping the arm beam in multiple directions.

[0029] The bottom of the control panel 1 is equipped with a rotation adjustment mechanism 7 for fixing the placement plate 2 after it rotates;

[0030] Specifically, a placement seat 3 is set on the top of the operating table 1 to place the arm beams, and the arm beams are fixed in multiple directions by a limiting and abutting mechanism 6, which ensures the stability of the arm beams during the welding process, helps to reduce welding deformation and weld defects, and improves welding quality.

[0031] The limiting and abutting mechanism 6 includes two fixed guide rails 61 fixedly installed on the top of the placement plate 2. The interior of the placement seat 3 is provided with a groove 62 for placing the two fixed guide rails 61. The top of the fixed guide rails 61 is fixedly installed with a first cylinder 63 by bolts. The extension end of the first cylinder 63 is fixedly installed with an abutting seat 64 for clamping the arm beam in the horizontal direction. The abutting seat 64 is used in conjunction with the abutting protrusion 5. The interior of the fixed rail is provided with a guide component 60 for pushing the seat to slide in an directional manner.

[0032] In this embodiment, the arm beam to be welded is placed in the storage slot 4 at the top of the placement seat 3. First, the two first cylinders 63 are activated, which respectively drive the two abutment seats 64 to retract, pressing the arm beam against the abutment seats 64. The arm beam is then fixed between the abutment seats 64 and the abutment protrusion 5. Simultaneously, the two second cylinders 82 are activated, which push the push rod 83 to rotate at the connecting seat 84, pressing the adhesive layer seat 11 at the top of the push rod 83 down onto the top of the arm beam, providing vertical support to the arm beam. The pressing and fixing mechanism is as follows: when the first cylinder 63 pushes the abutment seat 64 to move, the guide slider 602 at the bottom of the abutment seat 64 will slide in the guide groove 601 to provide guidance for the movement of the abutment seat 64. When welding the curved arm beam, the rotatable placement plate 2 can drive the column 71 to rotate and adjust in the operating table 1. After adjusting to a suitable position, the third cylinder 703 is activated to drive the bonding seat 704 to move upward, so that the top of the bonding seat 704 presses against the operating table 1 to limit the column 71.

[0033] The guide assembly 60 includes two guide grooves 601 formed in the fixed guide rail 61. Guide sliders 602 are slidably installed inside the two guide grooves 601. The top of the guide sliders 602 is fixedly installed to the bottom of the abutment seat 64. A support corner seat 603 is fixedly installed between the top of the guide sliders 602 and the surface of the abutment seat 64. A pressing mechanism 8 for pressing the arm beam vertically is installed on the top of the placement plate 2.

[0034] Specifically, when the first cylinder 63 pushes the abutment seat 64 to move, the guide slider 602 at the bottom of the abutment seat 64 will slide in the guide groove 601 to provide guidance for the movement of the abutment seat 64, and the support corner seat 603 is set between the top of the guide slider 602 and the surface of the abutment seat 64 to provide a certain support force for the abutment seat 64.

[0035] The pressing mechanism 8 includes two bases 81 fixedly installed on the top of the placement plate 2. A second cylinder 82 is fixedly installed on the front of each of the two bases 81. The extension end of the second cylinder 82 passes through the surface of the base 81 and is connected to a push rod 83. A connecting seat 84 is fixedly installed on the surface of the base 81. A short rod 85 is rotatably installed on the surface of the connecting seat 84. One end of the short rod 85 is fixedly installed on the surface of the push rod 83.

[0036] Furthermore, the two second cylinders 82 are activated, which can push the push rod 83 to rotate at the connecting seat 84, pressing the rubber layer seat 11 at the top of the push rod 83 down onto the top of the arm beam, providing vertical pressure and fixation for the arm beam.

[0037] The top of the push rod 83 is movably sleeved with the insert rod 9, the surface of the insert rod 9 is threaded with a limit bolt 10, the lower end of the insert rod 9 is fixedly installed with a rubber layer seat 11, and the surface of the insert rod 9 is integrally formed with an abutment ring 12.

[0038] It should be noted that the rotatable limiting bolt 10 can be detached from the surface of the insert rod 9, and the insert rod 9 can be removed from the surface of the push rod 83. Other rubber layer seats 11 can be replaced to adapt to different types of arm beams for use.

[0039] The rotation adjustment mechanism 7 includes a column 71 fixedly installed at the bottom of the placement plate 2. The column 71 is rotatably installed on the surface of the operating table 1. Limiting rings 72 are provided at the top and bottom of the operating table 1. Both limiting rings 72 are fixedly installed on the surface of the column 71. A fixing member 70 is installed at the bottom of the column 71.

[0040] It is worth noting that both limiting rings 72 are fixedly installed on the surface of the column 71, thereby restricting the column 71 to rotate and adjust only within the operating table 1 and preventing it from moving vertically. The fixing member 70 is provided to limit and fix the column 71.

[0041] The fastener 70 includes a disc 701 fixedly installed at the bottom of the column 71. Two grooves 702 are installed inside the disc 701. The two grooves 702 are located on both sides of the column 71. A third cylinder 703 is fixedly installed inside the two grooves 702 through a plate. A fitting seat 704 is fixedly installed at the extended end of the top of the third cylinder 703.

[0042] Furthermore, the rotatable placement plate 2 drives the column 71 to rotate and adjust within the operating table 1. After adjusting to a suitable position, the third cylinder 703 is activated to drive the bonding seat 704 to move upward, so that the top of the bonding seat 704 presses against the operating table 1, thereby limiting the position of the column 71.

[0043] A display rack 13 is fixedly installed at the bottom of the control panel 1, and a control console 14 is provided on one side of the display rack 13;

[0044] The control console 14 is electrically connected to the first cylinder 63, the second cylinder 82 and the third cylinder 703, and is used to control the use of the first cylinder 63, the second cylinder 82 and the third cylinder 703. The power distribution box is installed on the display frame 13.

[0045] The device places the arm beam to be welded in the storage slot 4 on top of the placement seat 3. First, the two first cylinders 63 are activated, which drive the two abutment seats 64 to retract, pressing the arm beam between the abutment seats 64 and the abutment protrusion 5. At the same time, the two second cylinders 82 are activated, which push the push rod 83 to rotate at the connecting seat 84, pressing the top of the adhesive layer seat 11 of the push rod 83 down to the top of the arm beam, providing vertical pressure and fixation for the arm beam. When the first cylinder 63 pushes the abutment seat 64 to move, the guide slider 602 at the bottom of the abutment seat 64 will slide in the guide groove 601, providing guidance for the movement of the abutment seat 64. When welding the bent arm beam, the placement plate 2 can be rotated to rotate and adjust the column 71 in the operating table 1. After adjusting to the appropriate position, the third cylinder 703 is activated to move the bonding seat 704 upward, so that the top of the bonding seat 704 presses against the operating table 1, thereby limiting the position of the column 71.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
