Description

Technical Field

[0001] This utility model relates to the field of loader seat beam welding technology, specifically a new type of automatic welding clamping fixture for loader seat beams. Background Technology

[0002] The loader seat beam is a core load-bearing component of the loader cab, installed at the bottom of the cab. Its main function is to support the driver's seat and control components, while also connecting the cab frame to the chassis to enhance the overall structural rigidity. It not only bears the weight of the driver and passengers but also disperses and transmits vibrations and impact loads during driving and operation, ensuring driver safety and operational stability. This component is mostly made of high-strength steel plates, stamped and welded. Some are equipped with reinforcing ribs and buffer bushings to improve fatigue resistance and shock absorption. The surface is treated with rust prevention to adapt to harsh environments such as mines and construction sites. Its design directly affects operating comfort and overall machine safety, making it an indispensable key structural component of the loader cab. The loader seat beam welding fixture is a specialized piece of equipment specifically designed for welding loader seat beams. Its core function is to precisely position the various stamped components of the seat beam. A dedicated positioning mechanism and clamping device fix the workpiece position, ensuring the connection accuracy of each component during welding and preventing deformation.

[0003] Traditional loader seat beam assembly structural components have many product specifications, with varying lengths, widths, and heights. Existing welding clamping fixtures cannot achieve adaptability adjustments and often can only adjust the length or width clamping mechanism. During the welding process, displacement and offset are prone to occur, resulting in a high defect rate. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a novel automatic welding and clamping fixture for loader seat beams, thereby solving the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel automatic welding clamping fixture for loader seat beams, comprising a fixture main board and left and right fixed seats located on the upper part of the fixture main board. A side baffle assembly is fixedly installed on the top of the fixture main board on one side above the left and right fixed seats. A side push unit is fixedly installed on the top of the fixture main board away from the side baffle assembly. A raised seat is fixedly installed on the opposite side of the tops of the left and right fixed seats. A movable side pull assembly is provided on the upper part of the right fixed seat. A rotating pressing assembly is fixedly installed on the top of both the left and right fixed seats. Side pull limit blocks are fixedly installed on both sides of the rotating pressing assembly on the top of the right fixed seat. Positioning stop pins are fixedly installed on both sides of the rotating pressing assembly on the top of the left fixed seat. The loader seat beam body is provided above the left and right fixed seats.

[0006] Preferably, the side-push unit includes a side-push bracket, which is fixedly installed on the top of the tooling main board. A cylinder is fixedly installed on the outer side of the side-push bracket. A movable rod is fixedly installed on the movable end of the cylinder, and a push block is fixedly installed on the end of the movable rod away from the cylinder.

[0007] Through the above technical solution, the cylinder can drive the movable rod to drive the push block to perform linear reciprocating motion, which can apply a stable lateral thrust to the loader seat beam body, and form a two-way positioning constraint with the side stop assembly, providing power support for the precise positioning of the seat beam body.

[0008] Preferably, the number of the side push units and the side guard components are the same and correspond one-to-one. The horizontal axes of the side push units and the side guard components are located on the same horizontal line. Both the push block and the side guard components are in contact with the loader seat beam body.

[0009] Through the above technical solution, the corresponding setting and coaxial arrangement of the side push unit and the side stop assembly ensure that the lateral thrust and the blocking force form an effective counterforce on the same straight line. The contact connection between the push block and the side stop assembly and the seat beam body can accurately limit the seat beam body to the preset lateral position and avoid lateral displacement during the welding process.

[0010] Preferably, there are two identical side tension limit blocks and positioning pins, and the two side tension limit blocks and the two positioning pins are symmetrically distributed about the axis of the loader seat beam body.

[0011] Through the above technical solution, two sets of symmetrically distributed side tension limit blocks and positioning pins can form symmetrical constraints from both sides of the loader seat beam body, ensuring that the loader seat beam body will not shift during the welding process.

[0012] Preferably, the side pull limit block adopts an inverted "L" shape structure, the positioning stop pin adopts an "l" shape structure, and both the side pull limit block and the positioning stop pin are in contact with the loader seat beam body.

[0013] Through the above technical solution, the structural design of the inverted "L"-shaped side pull limit block and the "l"-shaped positioning stop pin can be precisely adapted to the outer contour of the loader seat beam body, enhancing the posture stability of the seat beam body during the welding process.

[0014] Preferably, the movable side-pull assembly includes a second cylinder, a connecting rod is fixedly installed at the movable end of the second cylinder, a connecting plate is fixedly installed at the end of the connecting rod away from the second cylinder, a guide rail, a right limit block and a left limit block are fixedly installed at the top of the right fixed seat, a slider is slidably installed on the upper part of the guide rail, a movable plate is provided at the top of the slider, and the movable plate and the connecting plate are fixedly connected.

[0015] Through the above technical solution, cylinder two can drive the movable plate through the connecting rod and connecting plate. Relying on the sliding cooperation of the guide rail and the slider, the movable plate can move smoothly in a straight line, thereby driving the side pull limit block to complete the application of lateral tension, providing an adjustable lateral positioning force for the seat beam body.

[0016] Preferably, the axes of the cylinder, connecting rod, connecting plate and movable plate are located on the same horizontal line, the right limiting block and the left limiting block are distributed on both sides of the movable plate, the side pulling limiting block is fixedly connected to the movable plate, and the guide rail and slider are symmetrically distributed at the bottom of the movable plate.

[0017] Through the above technical solution, the right limit block and the left limit block can strictly limit the travel range of the movable plate, and avoid deformation of the loader seat beam body due to large clamping force.

[0018] Compared with the prior art, this utility model provides a novel automatic welding clamping fixture for loader seat beams, which has the following beneficial effects: This new type of automatic welding clamping fixture for loader seat beams forms a two-way lateral constraint through the coaxial arrangement of the side push unit and the side stop assembly. Combined with the controllable lateral tension of the movable side pull assembly and the symmetrically distributed positioning pins and side pull limit blocks, it achieves all-round limitation of the seat beam body from the longitudinal and lateral directions. The structural design of the inverted "L"-shaped side pull limit block and "l"-shaped positioning pin can accurately adapt to the outer contour of the seat beam, ensuring no displacement deviation of the seat beam during welding, guaranteeing welding accuracy, and has high practicality. At the same time, it can also be adapted to the welding clamping of loader seat beams of different sizes. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: like Figure 1-7 As shown, this utility model provides a novel automatic welding clamping fixture for loader seat beams, including a fixture main board 1 and a left fixed seat 2 and a right fixed seat 3 located on the upper part of the fixture main board 1. A side baffle assembly 6 is fixedly installed on the top of the fixture main board 1 on one side above the left fixed seat 2 and the right fixed seat 3. A side push unit 4 is fixedly installed on the top of the fixture main board 1 away from the side baffle assembly 6.

Side pull limit blocks 8 are fixedly installed on both sides of the rotating pressing assembly 9 on the top of the right fixed seat 3. Positioning stop pins 11 are fixedly installed on both sides of the rotating pressing assembly 9 on the top of the left fixed seat 2. A loader seat beam body 10 is provided above the left fixed seat 2 and the right fixed seat 3.

[0023] Example 2: like Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0024] Specifically, the side-push unit 4 includes a side-push bracket 401, which is fixedly installed on the top of the tooling main board 1. A cylinder 402 is fixedly installed on the outer side of the side-push bracket 401. A movable rod 403 is fixedly installed on the movable end of the cylinder 402, and a push block 404 is fixedly installed on the end of the movable rod 403 away from the cylinder 402. The advantage is that the cylinder 402 can drive the movable rod 403 to drive the push block 404 to make linear reciprocating motion, which can apply a stable lateral thrust to the loader seat beam body 10. Together with the side stop assembly 6, it forms a two-way positioning constraint, providing power support for the precise positioning of the seat beam body.

[0025] Specifically, the number of side-push units 4 and side-block components 6 are the same, and they correspond one-to-one. The horizontal axes of the side-push units 4 and side-block components 6 are on the same horizontal line. Both the push block 404 and the side-block components 6 are in contact with the loader seat beam body 10. The advantage is that the corresponding setting and coaxial arrangement of the side-push units 4 and side-block components 6 ensure that the lateral thrust and blocking force form an effective counterforce on the same straight line. The contact connection between the push block 404 and the side-block components 6 and the seat beam body can accurately limit the seat beam body to a preset lateral position, avoiding lateral displacement during the welding process.

[0026] Example 3: like Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, two identical side tension limit blocks 8 and positioning pins 11 are provided, and the two side tension limit blocks 8 and the two positioning pins 11 are symmetrically distributed about the axis of the loader seat beam body 10. The advantage is that the two sets of symmetrically distributed side tension limit blocks 8 and positioning pins 11 can form symmetrical constraints from both sides of the loader seat beam body 10, ensuring that the loader seat beam body 10 will not shift during the welding process.

[0028] Specifically, the side tension limit block 8 adopts an inverted "L" shape, and the positioning pin 11 adopts an "l" shape. Both the side tension limit block 8 and the positioning pin 11 are in contact with the loader seat beam body 10. The advantage is that the structural design of the inverted "L" shaped side tension limit block 8 and the "l" shaped positioning pin 11 can be precisely adapted to the outer contour of the loader seat beam body 10, enhancing the posture stability of the seat beam body during the welding process.

[0029] Example 4: like Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0030] Specifically, the movable side-pull assembly 7 includes a second cylinder 701. A connecting rod 702 is fixedly installed at the movable end of the second cylinder 701. A connecting plate 703 is fixedly installed at the end of the connecting rod 702 away from the second cylinder 701. A guide rail 706, a right limiting block 707, and a left limiting block 708 are fixedly installed at the top of the right fixed seat 3. A slider 705 is slidably installed on the upper part of the guide rail 706. A movable plate 704 is provided at the top of the slider 705. The movable plate 704 and the connecting plate 703 are fixedly connected. The advantage is that the second cylinder 701 can drive the movable plate 704 through the connecting rod 702 and the connecting plate 703. Relying on the sliding cooperation between the guide rail 706 and the slider 705, the movable plate 704 can move smoothly in a straight line, thereby driving the side-pull limiting block 8 to complete the application of lateral tension, providing an adjustable lateral positioning force for the seat beam body.

[0031] Specifically, the axes of cylinder 701, connecting rod 702, connecting plate 703, and movable plate 704 are located on the same horizontal line. Right limit block 707 and left limit block 708 are distributed on both sides of movable plate 704. Side pull limit block 8 is fixedly connected to movable plate 704. Guide rail 706 and slider 705 are symmetrically distributed at the bottom of movable plate 704. The advantage is that right limit block 707 and left limit block 708 can strictly limit the stroke range of movable plate 704, preventing deformation of the loader seat beam body 10 due to excessive clamping force.

[0032] Working principle: During use, the operator uses hoisting equipment to lift the loader seat beam body 10 onto the upper part of the tooling main board 1, and places the loader seat beam body 10 on the raised seat 5 at the top of the left fixed seat 2 and the right fixed seat 3. At this time, the side push unit 4 and the moving side pull assembly 7 are activated. Cylinder 1 402, through the movable rod 403 and the push block 404, pushes the loader seat beam body 10 longitudinally until the push block 404 and the side block assembly 6 initially contact the loader seat beam body 10. Cylinder 2 701, through the connecting rod 702 and the connecting plate 703, pulls... The movable plate 704 moves toward the loader seat beam body 10 until the side pull limit block 8 hooks onto the loader seat beam body 10 and the positioning stop pin 11 abuts against the loader seat beam body 10. Then, the rotating pressing component 9 is activated at the same time to press the loader seat beam body 10. At this time, the tooling clamps the loader seat beam body 10, which facilitates the subsequent welding operation. After welding is completed, the rotating pressing component 9, the moving side pull component 7, and the side push unit 4 are released in sequence, and then the loader seat beam body 10 is lifted off the tooling main plate 1.

[0033] 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.
