Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology in mechanical manufacturing, specifically to welding tooling for tractor cab door handles. Background Technology

[0002] With the vigorous development of agricultural machinery, agricultural tractors have become one of the important tools used in agricultural cultivation. In the production and processing of door handles for agricultural tractors, welding operations are required. Therefore, precise positioning and stable fixing of the door handle workpiece during the welding process are crucial to ensure welding position accuracy, reduce welding deformation, and improve the consistency of welding quality.

[0003] However, in the existing technology, the welding process of door handrails suffers from unstable positioning, which reduces the processing quality. Utility Model Content

[0004] To address the above problems, this utility model provides a simple, convenient, and reliable welding fixture for tractor cab door handles.

[0005] The technical solution of this utility model is: a welding fixture for the door armrest of a tractor cab, comprising:

[0006] The fixing component includes a welding fixture table, a bracket located in the middle of one side of the top of the welding fixture table, a track screwed to the bottom of the bracket, and a T-shaped connecting block on the track.

[0007] The clamping component includes a sliding block slidably connected to a T-shaped connecting block, a first pressing block located at the center of the bottom end of the sliding block, a second pressing block engaged with the lower end of the first pressing block, a memory spring located between the first pressing block and the second pressing block, and a clamping opening located at the center of the bottom end of the second pressing block, with notches on both sides of the clamping opening.

[0008] The fixing component also includes a strip groove located in the center of the T-shaped connecting block.

[0009] The clamping component also includes a pair of symmetrically arranged clamping groups, each clamping group including two fixed rods located at one bottom end of the sliding block, a torsion spring connected between the two fixed rods, and an irregularly shaped push block sleeved on the torsion spring.

[0010] The clamping component also includes a locking block located on one side of the end of the first extrusion block and a locking groove on the side of the second extrusion block. The locking block engages in the locking groove and slides up and down within the locking groove.

[0011] The clamping component also includes a pressure groove on the upper end of the second pressing block, and the upper end of the irregularly shaped pushing block is located in the pressure groove position.

[0012] The clamping component also includes an anti-slip pad located at one end below the irregularly shaped push block, the anti-slip pad being located within a notch on one side of the clamping opening.

[0013] It also includes a rotating telescopic component, which includes a threaded rod located at the center of the upper end of the sliding block and a nut located on the strip groove, with the threaded rod connected to the nut.

[0014] In operation, when welding the tractor cab handrail, this invention pushes the sliding block, causing it to slide on the T-shaped connecting block and move to the desired position. The handrail is then pressed against the clamping opening at the bottom of the clamping component. The handrail applies force to the clamping opening, causing it to move the second pressure block towards the first compression block. The memory spring is compressed. During this process, the second compression block drives the shaped push block to rotate, with the upper end rotating upwards. This causes the torsion spring to rotate, and the lower end of the shaped push block rotates in the same direction, clamping the handrail of the tractor cab door through the notches on both sides of the clamping opening. When the handrail reduces the force applied to the clamping opening, the torsion spring returns to its original position, and the shaped push block releases its force, preventing excessive force from the handrail on the anti-slip pad, which could lift the anti-slip pad or even damage the clamping opening. This invention, through its clamping component, enhances the clamping force while preventing excessive vibration that could damage the clamping opening and the anti-slip pad, thus preventing the anti-slip pad from being dragged or scraped off.

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.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this utility model is a welding fixture for the door handle of a tractor cab, comprising:

[0025] The fixing component includes a welding fixture 10, a bracket 11 located in the middle of one side of the top of the welding fixture 10, a track 12 screwed to the bottom of the bracket 11, and a T-shaped connecting block 13 on the track 12.

[0026] The clamping component includes a sliding block 20 slidably connected to the T-shaped connecting block 13, a first pressing block 21 located at the center of the bottom end of the sliding block 20, a second pressing block 211 engaged with the lower end of the first pressing block 21, a memory spring 22 located between the first pressing block and the second pressing block, and a clamping opening 23 located at the center of the bottom end of the second pressing block, wherein notches are provided on both sides of the clamping opening 23.

[0027] The welding fixture 10 is the basic load-bearing component. The bracket 11 is welded to the middle of one side of its top end to fix the track 12. The track 12 is fixed and moved by the T-shaped connecting block 13 through screw connection. The strip groove 131 of the T-shaped connecting block 13 provides space for the rotating telescopic component. The sliding block 20 slides on the connecting block. The first pressing block 21 is fixed at its bottom end and is engaged with the second pressing block 211 with the slot 213 through the locking block 212 to achieve relative sliding. The memory spring 22 assists in the reset between the two. The clamping port 23 directly clamps the door handle.

[0028] The fixing component also includes a strip groove 131 located in the center of the T-shaped connecting block 13;

[0029] The groove 131 provides space for the threaded rod 30 to move while also helping to fix the threaded rod 30 in place.

[0030] The clamping component also includes a pair of symmetrically arranged clamping assemblies. Each clamping assembly includes two fixed rods 201 located at one bottom end of the sliding block 20, a torsion spring 24 connected between the two fixed rods 201, and a shaped push block 25 sleeved around the torsion spring 24. The shaped push block 25 is C-shaped or I-shaped and can be configured according to actual conditions. The upper end of the shaped push block 25 is used to connect to the pressure groove 214, and the lower end is used to connect to the notch on one side of the clamping opening 23.

[0031] The clamping component also includes a locking block 212 located on one side of the end of the first extrusion block and a locking groove 213 located on the side of the second extrusion block 211. The locking block 212 engages in the locking groove 213 and slides up and down within the locking groove 213.

[0032] The fixing rod 201 fixes the torsion spring 24 at both ends of the bottom of the sliding block 20. One end of the irregularly shaped push block 25 outside the torsion spring 24 is in the pressure groove 214 of the second extrusion block 211, and drives the second extrusion block 211 by pushing the pressure groove 214.

[0033] The clamping component also includes a pressure groove 214 on the upper end of the second pressing block 211, and one upper end of the irregular push block 25 is located in the pressure groove 214.

[0034] The compression of the spring causes the pressure groove 214 to move upward, which in turn causes the irregularly shaped push block 25 to rotate, so that the other end of the irregularly shaped push block 25 fits against the handrail.

[0035] The clamping component also includes an anti-slip pad 26 located at one end below the irregular push block 25, the anti-slip pad 26 being located in a notch on one side of the clamping opening 23;

[0036] The anti-slip mat 26 not only prevents the handrail from being scratched, but also increases friction and enhances contact stability.

[0037] When welding is required on the tractor cab handrail, push the sliding block 20 to slide it on the T-shaped connecting block 13 and move it to the required position. The handrail is then pressed against the clamping opening 23 at the bottom of the clamping component. The handrail applies a force to the clamping opening 23, causing the clamping opening 23 to move the second pressure block towards the first extrusion block 21. The memory spring 22 is compressed. During this process, the second extrusion block 211 drives the shaped push block 25 to rotate, with the upper end rotating upwards. The torsion spring 24 is driven, and the lower end of the shaped push block 25 rotates in the same direction, clamping onto the handrail of the tractor cab door through the notches on both sides of the clamping opening 23. When the handrail reduces the force applied to the clamping opening 23, the torsion spring 24 rotates back, and the shaped push block 25 also releases its force, preventing the handrail from exerting excessive force on the anti-slip pad 26, which could lift the anti-slip pad 26 or even damage the clamping opening 23.

[0038] This solution, through the clamping components, enhances the clamping force while preventing excessive vibration from damaging the clamping opening 23 and the anti-slip pad 26, thus preventing the anti-slip pad 26 from being dragged or scraped off.

[0039] However, due to the different sizes of the handrails, the clamping opening 23 needs to be moved up and down to increase the stability of the clamping.

[0040] Specifically, it also includes a rotating telescopic component, which includes a threaded rod 30 located at the center of the upper end of the sliding block 20 and a nut 31 located on the strip groove 131. The threaded rod 30 is connected to the nut 31.

[0041] The threaded rod 30 is located on the upper end of the sliding block 20 and cooperates with the nut 31 on the strip groove 131. When rotated, it drives the sliding block 20 to adjust its position.

[0042] When the distance between the clamping port 23 and the handrail is too far or too close, the entire clamping component can be adjusted by rotating the threaded rod 30. The threaded rod 30 can be rotated on the nut 31 to adjust the angle and length to accommodate handrails with different bending angles, while ensuring that the clamping port 23 is fixed on the handrail.

[0043] This invention adjusts the position of the clamping component by setting a rotating telescopic component, making the tooling more adaptable and able to handle tractor cab handrails of different sizes.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
