Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a chassis fillet welding fixture. Background Art

[0002] In the machinery manufacturing and assembly industry, welding is a common connection method, and its accuracy and efficiency directly affect the quality and production efficiency of the final product. Especially when welding the four corners of the chassis or similar box structures, how to ensure the correct positioning of each component before welding and prevent the displacement of components during welding becomes the key to improving welding quality.

[0003] Traditional welding fixture designs often focus on simple clamping mechanisms and lack consideration for specific shapes or special welding needs. Especially when dealing with arc welding at the four corners of a box, it is difficult for traditional fixtures to achieve accurate positioning and stable clamping of the box and the arc strip to be welded, which not only affects the beauty and consistency of the welded seam, but also may lead to product failure in the high-standard precision manufacturing process. In addition, the splashing of sparks during welding may also damage the fixture or affect the safety of the operator, and traditional fixtures often have insufficient protective measures for this.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] Furthermore, an elbow is fixedly connected to the top of the buckle strip.

[0010] Furthermore, the box clamping mechanism includes a positioning frame, a cylinder is connected to the side of the positioning frame, a push plate is connected to the telescopic end of the cylinder, a push head is connected to the side of the push plate, and the push heads are distributed at equal intervals along the length direction of the push plate;

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By combining a trapezoidal base with a fixed platform, and setting a baffle and buckle strip at the waist of the base, this fixture effectively improves the stability and accuracy of the welding operation. The trapezoidal base enhances the stability of the entire structure, while the design of the baffle and buckle strip ensures the precise positioning of the box during the clamping process, thus solving the positioning problem of traditional fixtures when handling special shape welding.

[0037] The side of the first connecting plate 314 is connected with a rounded push piece 32, which is a key component used in the present fixture to position and clamp the arc strip 5. Its design ensures that the arc strip 5 can be accurately aligned with the four corners of the box body 4 to be welded. The bottom of the base 311 is connected with a box clamping mechanism 35, and the box body 4 is clamped between the box clamping mechanism 35 and the fixed platform 31. This design not only ensures the stable positioning of the box body 4 before welding, but also effectively prevents the splash of sparks during welding through the use of the shielding cover 34, thereby improving the safety of operation; the arc strip 5 is clamped between the rounded push piece 32 and the shielding cover 34, and this setting ensures that the arc strip 5 can maintain the correct position during welding, thereby improving the welding quality.

[0038] See also Figure 3 The top of the buckle strip 312 is fixedly connected with an elbow 3121. The design of the elbow 3121 takes into account the convenience of operation and the reliability of clamping. Through the engagement with the baffle strip on the outside of the box opening, the stability of the box 4 is further enhanced.

[0039] See also Figure 3-4 The clamping mechanism 35 includes a positioning frame 351, a cylinder 352 is connected to the side of the positioning frame 351, a push plate 353 is connected to the telescopic end of the cylinder 352, a push head 354 is connected to the side of the push plate 353, and the push heads 354 are evenly spaced along the length of the push plate 353; this design makes the clamping force more uniform, effectively improving the stability of the clamping process and the accuracy of the welding operation. A second connecting plate 3511 is fixedly connected to one side of the bottom of the positioning frame 351, and the second connecting plate 3511 is connected to the side of the base 311 by screws. This structural design enhances the stability of the entire clamping mechanism and ensures durability during repeated use.

[0040] See also Figure 3-4The rounded push piece 32 includes a pin seat 321, a push handle 322 is rotatably connected to the pin seat 321, an adapter seat 323 is rotatably connected to the inner side of the push handle 322, a positioning plate 324 is connected to the side of the adapter seat 323, a clamping plate 325 corresponding to the push head 354 is connected to the side of the positioning plate 324, and an arc groove 3251 is provided at one end of the clamping plate 325; this coherent design allows the operator to achieve precise clamping and positioning of the arc strip 5 through simple manual operation, thereby improving the efficiency and quality of the welding operation.

[0041] See also Figure 5 The bottom of the base 311 is fixedly connected to a base 33, and the base 33 includes a bottom plate 331, and the bottom plate 331 is connected to the table top 2 by screws, thereby ensuring the stability of the entire fixture; and the upper end surface of the bottom plate 331 is connected to a vertical plate 332, and the top of the vertical plate 332 is fixedly connected to a top plate 333, and the top plate 333 and the bottom of the bottom plate 331 are connected by screws. This structural design not only provides a solid support for the fixture, but also facilitates the installation and movement of the fixture, meeting the needs of different working environments.

[0042] The working principle of the utility model is:

[0043] When in use, the four corners of the box body 4 to be welded are inserted between the push head 354 and the stop bar 313. During the placement process, the stop bar 313 located at the waist of the base 311 will block the outside of the four corners of the box body 4, and the elbow 3121 set at the top of the buckle bar 312 will be stuck on the stop bar outside the box opening;

[0044] Then, under the push of the cylinder 352, the cylinder 352 moves toward the position where the blocking bar 313 is located, and then the box body is clamped between the push head 354 and the blocking bar 313, and the shielding cover 34 provided on the box clamping mechanism 35 can wrap the box clamping mechanism 35 to prevent sparks generated during the welding process from falling onto the box clamping mechanism 35;

[0045] After the box body 4 is fixed, it is necessary to manually push the push handle 322 upwards. As the push handle 322 moves upwards, the clamping plate 325 will move away from the pushing head 354, and then the arc strip 5 to be welded is inserted into the four corners of the box body 4 to be welded, and the edge of the arc strip 5 is aligned with the notch position of the box body 4, and then the push handle 322 is pushed downwards. As the push handle 322 is pushed downwards, the clamping plate 325 will move closer to the pushing head 354, and as the clamping plate 325 moves, the arc strip 5 and the box body 4 will fit tightly together, which can avoid misalignment between the arc strip 5 and the box body 4 during the welding process, thereby improving the welding accuracy.

[0046] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
