[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] like Figures 1-5 The automatic welding fixture for mop frames shown includes a fixture table 1, on which a support mechanism, a rotating mechanism, a clamping mechanism 9, and a power distribution box 15 are provided.

[0018] The tooling table 1 serves as the basic support structure for the entire welding tooling, bearing important components such as the support mechanism, rotating mechanism, clamping mechanism 9, and electrical distribution box 15.

[0019] The support mechanism is a key part to ensure the accurate positioning and stable support of each part of the mop frame, including the first support component 2, the second support component 3, and the bearing bracket 4.

[0020] Bearing bracket 4: Two bearing brackets 4 are fixed on the tooling table 1 one after the other. The upper part of the bearing bracket 4 is equipped with a bearing, and the rotating shaft 5 can rotate flexibly through the bearing, which provides support for the rotating shaft 5.

[0021] like Figure 5As shown, the first part 12 is a U-shaped sheet metal part, which is supported and limited by the second support component 3; the second part 13 is a cover part, which has a downward-opening box part 131 at the front and a downward-L-shaped bent part 132 at the rear; the third part 14 is an end seal part that matches the front end of the second part 13. The bent part 132 of the second part 13 covers the upper part and rear side of the first part 12 and is welded together. The rear side of the box part 131 of the second part 13 is welded to the front side of the first part 12. The third part 14 is welded to the front side of the box part 131 of the second part 13. The three parts are tightly fitted and welded together.

[0022] The first support assembly 2 is located between the two bearing brackets 4 and includes a first connecting plate 21, a positioning support frame 22, a positioning block 23, and a rotating clamping mechanism 26. The first connecting plate 21 is vertically arranged, and its lower part is fixed to the rotating shaft 5, serving to connect and support other components. The positioning support frame 22 is horizontally fixed to the middle of the rear side of the first connecting plate 21, used to support the front of the second part 13 of the mop frame upward, ensuring the stability of the second part 13 in the horizontal direction. The positioning block 23 is fixed to the upper part of the rear side of the first connecting plate 21, and its rear side is provided with a positioning groove 24 and a positioning protrusion 25, which cooperate with each other. In this embodiment, the positioning... The protrusion 25 is an arched protrusion that matches the recess in the middle of the third part 14, providing accurate positioning and upward support for the third part 14 of the mop frame. The rotary pressing mechanism 26 includes a rotary motor 261 and a pressing cylinder 263. The rotary motor 261 is fixedly installed on the top of the first connecting plate 21. The pressing cylinder 263 is connected and fixed to the output shaft of the rotary motor 261 through the cross arm 262. A pressing head 264 is provided at the lower end of the pressing cylinder 263. During operation, the pressing head 264 of the rotary pressing mechanism 26 can be rotated to a suitable position and pressed downward to the front of the second part 13, further fixing the second part 13 and preventing it from shifting during the welding process, thus ensuring the accuracy of the welding.

[0023] The second support assembly 3 is located at the rear of the bearing bracket 4, including a second connecting plate 31 and a positioning upper plate 32, a positioning middle plate 33, and a positioning bottom plate 34 fixed to the rear side of the second connecting plate 31. The second connecting plate 31 is vertically arranged, with its middle part fixed to the rotating shaft 5, responsible for connecting and supporting the positioning upper plate 32, the positioning middle plate 33, and the positioning bottom plate 34. The two positioning upper plates 32 are symmetrically arranged on both sides of the upper part of the second connecting plate 31, the positioning middle plate 33 is located in the middle of the second connecting plate 31, and the positioning bottom plate 34 is located at the bottom of the second connecting plate 31. For the first part 12 of the mop frame, it is a U-shaped... The first part 12 is a sheet metal part, with its bottom supported by a positioning base plate 34, its middle part located on both sides of a positioning middle plate 33, and its upper part located inside a positioning upper plate 32. This design allows the first part 12 to be accurately positioned and stably supported in three directions. At the same time, the inner side of the positioning upper plate 32 is provided with an upper positioning block 35, both sides of the positioning middle plate 33 are provided with middle positioning blocks 36, and the upper side of the positioning base plate 34 is provided with a lower positioning block 37. The distance between the three positioning blocks and the corresponding three positioning plates can be adjusted. These adjustable positioning blocks can be flexibly adjusted according to the different specifications of the first part 12, enhancing the versatility of the tooling.

[0024] The rotating mechanism is located in front of the rotating shaft 5 and includes a control motor 6 and a reducer 7. It is fixed to the tooling table 1 by a motor bracket 11 and drives the rotating shaft 5 to rotate through a coupling 8. Its function is to drive the first support assembly 2 and the second support assembly 3 installed on the rotating shaft 5, as well as the mop frame parts placed on the support assemblies, to rotate. Through rotation, welding of different parts of the mop frame can be achieved without manual adjustment of the parts, which greatly improves the efficiency and accuracy of welding. For example, when welding the corners or ring parts of the mop frame, the rotating mechanism can make the parts rotate along a preset trajectory, so that the welding equipment can weld the weld evenly and ensure the consistency of the welding quality.

[0025] The clamping mechanism 9 is located at the tail of the rotating shaft 5 and is a clamping cylinder 91 mounted on the tooling table 1. A clamping head 10 is located at the front end of the piston shaft 92 of the clamping cylinder 91. The clamping head 10 is rotatably mounted on the piston shaft 92. Its main function is to press the side of the second part 13 of the mop frame tightly against the first part 12 during the welding process. This ensures that the second part 13 and the first part 12 are tightly fitted together, preventing gaps from appearing during welding and thus ensuring the strength of the weld. Meanwhile, the rear end of the positioning plate 33 is... The end plate 38 is rotatably mounted and corresponds to the clamping head 10. The end plate 38 provides a relative support point for the clamping head 10. On the other hand, the rotatable end plate 38 and the clamping head 10 can clamp the lower vertical plate 1321 on the bent part of the second part 13. In this way, the lower vertical plate 1321 will not generate rotational friction with the top plate during rotation, thereby reducing the possibility of misalignment between parts. The rotating shaft 5 passes through the positioning plate 33, which helps to ensure the stability of the entire device during rotation.

[0026] Electrical components are installed in the distribution box 15 to control the operation of various electrical devices in this device. By controlling the electrical components, the starting, stopping, and speed adjustment of the rotating mechanism, the clamping mechanism 9, and other electrical equipment that may be involved in the welding equipment are realized, so as to ensure that the entire welding fixture can operate stably according to the preset program and requirements.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
