[0044] Example 1

[0045] like Figures 1-4 As shown, a welding fixture for a forklift drive axle includes a posture adjustment fixture. By locking the drive axle housing onto the posture adjustment fixture, the drive axle housing structure can be easily rotated and adjusted during operation.

[0046] The specific structure of the posture adjustment fixture is as follows:

[0047] The posture adjustment fixture includes an inner rotating fixture ring 1, on the inner sidewall of which a pair of sliding mounting parts are slidably connected, and the drive axle housing is locked between the sliding mounting parts.

[0048] Specifically, an annular flange plate 11 is fixedly connected to the inner sidewall of the inner rotating tooling ring 1; the sliding mounting part 12 is slidably connected to the annular flange plate 11.

[0049] Specifically, the aforementioned sliding mounting component 12 includes a slide seat 121 slidably connected to the annular flange plate 11 (the slide seat 121 has an arc-shaped groove corresponding to the shape of the annular flange plate 11, and the arc-shaped groove limits the sliding on the annular flange plate 11), and a fitting structure for fitting the end shaft of the drive axle housing is slidably connected to the slide seat 121; a compression locking screw 1211 is threadedly connected to the slide seat 121.

[0050] The sliding mounting piece can be adjusted by loosening the locking screw.

[0051] Meanwhile, the assembly structure includes a sleeve 122, the bottom of which is fixedly connected to a slide rod slidably connected to a slide block 121 (the slide block 121 has a cavity adapted to the slide rod); a spring 123 is sleeved on the slide rod, with both ends of the spring 123 fixedly connected to the slide rod and the slide block 121 respectively. During operation, the operator presses one side of the sleeve 122 towards the slide block 121. At this time, the slide rod retracts into the cavity of the slide block 121, the spring 123 is compressed, and the end shaft of the drive axle housing is sleeved into the sleeve 122, and positioned by the compression screw 1221 threaded on the sleeve 122. Similarly, the end shaft on the other side of the drive axle housing is sleeved onto the sleeve 122 and locked.

[0052] During operation, after the operator releases the extrusion screw 1221, the sliding mounting component is slidably adjusted. At this time, the drive axle housing rotates and adjusts its posture following the sliding mounting component. Then, the extrusion locking screw on the slide block 121 is extruded and locked to maintain the initial adjustment and positioning of the drive axle housing posture.

[0053] Example 2

[0054] like Figures 1-4 As shown, based on the structure of Embodiment 1, in order to further adjust the posture of the drive axle housing and facilitate welding by operators, the posture adjustment fixture also includes an outer flipping fixture ring concentrically arranged on the outside of the inner rotating fixture ring 1.

[0055] Specifically, the inner rotating tooling ring 1 is rotatably connected to the outer flipping tooling ring 3. The rotatable connection method is as follows: the two ends of the inner rotating tooling ring 1 are respectively fixedly connected to rotating shafts, and the rotating shafts are rotatably connected to the outer flipping tooling ring 3.

[0056] Meanwhile, a motor that drives the inner rotating tooling ring 1 to rotate is mounted on the outer flip tooling ring 3.

[0057] The top of the outer rotating tooling ring 3 is fixedly connected to a mounting base for mounting a motor 2, and the motor 2 is fixedly mounted on the mounting base; the output shaft of the motor 2 is fixedly mounted on a rotating shaft. During operation, the operator turns on the motor 2, which drives the inner rotating tooling ring 1 to rotate. During the rotation of the inner rotating tooling ring 1, the posture of the drive axle housing is adjusted to facilitate exposing the welding position towards the operator.

[0058] Example 3

[0059] like Figures 1-4 As shown, based on the structure of Embodiment 2, the forklift drive axle welding fixture further includes a fixture bracket 5 supported at the bottom of the outer tilting fixture ring 3. Both ends of the fixture bracket 5 are respectively fitted with push wheel mechanisms to push the outer tilting fixture to roll. Specifically, the push wheel mechanism includes a clamping wheel 61, which is rotatably connected to an adjusting rod 62 (the outer end of the adjusting rod 62 is fixedly connected to a handle). The adjusting rod 62 is slidably connected to the vertical part. The push wheel mechanism abuts against both sides of the outer tilting fixture ring 3.

[0060] The abutting wheel 61 includes a wheel frame, on which an abutting wheel is rotatably connected; the adjusting rod 62 is rotatably connected to the wheel frame.

[0061] During operation, the operator turns the handle. At this time, the clamping wheel 61 on one side moves forward and pushes the outer flip tooling ring 3 to roll on the tooling bracket 5, while the clamping wheel 61 on the other side moves backward and cooperates to clamp on the outer flip tooling ring 3. With the cooperation of the clamping wheels 61 on both sides, the outer flip tooling ring 3 can be easily pushed. During the pushing process, the drive axle housing is further flipped to adjust its posture.

[0062] To ensure smooth movement of the outward-flipping fixture ring 3 during the pushing process, arc-shaped sliding openings 31 are provided at both ends of the outward-flipping fixture ring 3. Specifically, vertically oriented portions (with pusher mechanisms mounted on the vertical portions) are integrally formed at both ends of the fixture bracket 5. A track guide rod 4, passing through the arc-shaped sliding opening 31, is fixedly connected to the vertical portion, and the track guide rod 4 slides within the arc-shaped sliding opening 31.

[0063] During the rolling process achieved by the guide rod 4, the outer flipping tooling ring 3 is supported by the guide rod 4. To increase the stability of the support, the guide rod 4 can be a rectangular track plate. During the flipping and rolling process of the outer flipping tooling ring 3, the guide rod 4 prevents the entire device from tipping over, and with the cooperation of the clamping wheel 61, further increases the stability.

[0064] According to the prior art, the bottom of the tool support 5 is fixedly connected with a plurality of U-shaped mounting seats; and the U-shaped mounting seats are threadedly connected with fastening screws.

[0065] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by those skilled in the art within the spirit and scope of the present application should also be within the protection scope of the present application.
