[0024] 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.

[0025] Please see Figures 1-4 This utility model provides a skirt frame welding fixture, including: a base 0, a coarse positioning mechanism, a clamping positioning mechanism, a hydraulic clamping mechanism, and a pressure plate 7;

[0026] The base 0 has a rectangular frame structure, and the skirt frame fixture is mounted on the support block 10 that can be detachably installed on the base 0; the coarse positioning mechanism is installed on the base 0 to perform preliminary positioning of the skirt frame fixture; the clamping and positioning mechanism is located on the base 0 to clamp and position the skirt frame fixture; the hydraulic clamping mechanism is located at the rib plate of the skirt frame fixture and clamps and limits the position through the hydraulic clamping mechanism; the pressure plate 7 is located at the thin plate of the skirt frame fixture and is installed on the base 0 by bolts to clamp the thin plate of the skirt frame fixture.

[0027] In practice:

[0028] like Figure 1 As shown, the coarse positioning mechanism includes several sets of clamping units 9 installed on one side of the base 0 and a rotary positioning 5 set at any end of the base 0. The skirt frame fixture is coarsely positioned by the rotary positioning 5 and the several sets of clamping units 9.

[0029] The clamping and positioning mechanism includes a pull-back clamping 3 and a clamping unit 9 installed on one end of the base 0 near the rotary positioning 5, a hydraulic cylinder 6 installed on the other side of the base 0, a manual pump 1 for driving the extension and retraction of the hydraulic cylinder 6, and several sets of rotary clamping and positioning 4 on the side of the base 0 near the hydraulic cylinder 6. The pull-back clamping 3 pulls back and positions the skirt frame fixture, and the several sets of rotary clamping and positioning 4 and the clamping unit 9 position and clamp the skirt frame fixture.

[0030] like Figure 2 As shown, as a further improvement: one or more sets of the bottom of several sets of rotating clamping positioning 4 are equipped with horizontally adjustable slide rails 8.

[0031] The hydraulic clamping mechanism includes a hydraulic cylinder 6 and a manual pump 1. The manual pump 1 drives the hydraulic cylinder 6 to extend and retract to clamp the skirt ribs.

[0032] like Figure 3 As shown, it should be further explained that the above-mentioned rotary clamping positioning 4 consists of a support column 401 mounted on the base 0 or slide rail 8, a clamping arm 402 axially connected to the support column 401, and a clamping head 403 on the clamping arm 402 for clamping the skirt frame fixture. The clamping arm 402 is equipped with a rotary plunger 2, which restricts the rotation of the clamping arm 402.

[0033] like Figure 4 As shown, the aforementioned rotary positioning 5 includes a rotary seat 501 mounted on the base 0. A slot is provided in the center of the rotary seat 501 to mount a positioning block 502. The positioning block 502 is mounted on the rotary seat 501 near its bottom via a rotating shaft 503. A knob plunger 504 is mounted on the rotary seat 501 above the rotating shaft 503 for positioning the positioning block 502. Quick-release pins 505 also pass through the rotary seat 501 and the positioning block 502.

[0034] When using this skirt welding fixture, the skirt workpiece is transferred to the support block 10 on the base 0 by the transfer device, and coarse positioning is performed by the rotation positioning 5 and the clamping unit 9.

[0035] After the rough positioning is completed, the vertical position of the skirt frame workpiece is fixed by the pull-back clamping 3. The pull-back clamping 3 consists of a positioning post and a pull-back head extending from the positioning post. A clamping bolt is installed on the pull-back head. Rotating the clamping bolt extends it towards the positioning post to pull back and clamp the skirt frame workpiece. Then, it is clamped by the clamping unit 9, and the manual pump 1 is started to drive the hydraulic cylinder 6 to extend and press against the skirt frame rib. The clamping arm 402 of the rotary clamping positioning 4 is adjusted to a suitable angle and then limited by the rotary plunger 2. Finally, it is clamped by the clamping head 403 to complete the clamping and positioning before welding.

[0036] Finally, the thin plate of the skirt frame workpiece is pressed by the pressure plate 7 to prevent welding deformation.

[0037] It should be noted that, except for hydraulic cylinder 6, all the above-mentioned clamping components not mentioned above use threaded connections for telescopic clamping, but are not limited to threaded connections. They can also use hydraulic, fixed pin, or other methods to achieve clamping. Those skilled in the art can make appropriate selections according to the actual working conditions, and will not be described in detail here.

[0038] Both the rotary positioning 5 and the rotary clamping positioning 4 are adjustable. The support block 10 can be replaced according to the corresponding model based on the actual working conditions.

[0039] Any content not described in detail in this specification is prior art known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
