Description

Technical Field

[0001] The present invention relates to the field of welding technology, in particular to a weld scar flattening jig and weld scar flattening equipment. Background Art

[0002] Currently, many products require welding during processing. For example, the battery lead-out conductive busbars of new energy vehicles are formed by welding aluminum semi-finished products with copper semi-finished products. However, after welding, the products usually leave weld scars due to overflowing solder. Since overflowing weld scars not only affect the appearance but also affect subsequent processing steps, the weld scars of the products need to be flattened or smoothed. In the existing technology, the weld scars are usually smoothed by pure manual grinding, which not only has high labor costs, but also has a long production cycle and extremely low production efficiency. Summary of the Invention

[0003] The main purpose of the present invention is to provide a weld scar flattening jig and a weld scar flattening device, aiming to solve the technical problem of high labor cost and low efficiency in existing weld scar removal.

[0004] Based on the above purpose, the present invention proposes a weld scar flattening jig, comprising an upper punch head, a scar flattening punch head and a product fixing seat;

[0005] The product fixing seat is provided with a bearing groove adapted to the product and a receiving groove adapted to the scar pressing punch, and the bearing groove is communicated with the receiving groove;

[0006] The scar pressing punch is embedded in the receiving groove, and the upper surface of the scar pressing punch protrudes from the bottom of the bearing groove. The upper surface of the scar pressing punch is provided with a scar pressing protrusion adapted to the size of the product welding area;

[0007] The upper punch is arranged above the scar pressing punch and is controlled by an external device to press down on the scar pressing punch or to move away from the scar pressing punch.

[0008] Furthermore, the scar-pressing protrusion includes a plurality of small protrusions, and the plurality of small protrusions enclose and form an outline of the shape of the product welding area.

[0009] Furthermore, it also includes a jig fixing seat, which is provided with a groove, the lower end of the scar pressing punch is embedded in the groove, and the product fixing seat is fixed on the jig fixing seat.

[0010] Furthermore, a limiting block extends from the product fixing seat toward the accommodating groove. When the scar pressing punch is embedded in the accommodating groove, the limiting block contacts the upper surface of the scar pressing punch to limit the scar pressing punch.

[0011] Furthermore, a conducting groove is provided on the bearing groove, and the conducting groove includes a side wall groove and a bottom groove connected to the side wall groove. The bottom groove is provided at the bottom of the bearing groove, and the side wall groove is provided on the side wall of the bearing groove and is located at a position corresponding to the bottom groove.

[0022] Reference Figure 1-2 The weld scar flattening jig provided by the present invention is used to flatten weld scars with overflowing solder, specifically, it includes an upper punch head 200, a scar flattening punch head 300 and a product fixing seat 400; wherein, the product fixing seat 400 is provided with a bearing groove 410 adapted to the product 100 and a receiving groove 420 adapted to the scar flattening punch head 300, and the bearing groove 410 is communicated with the receiving groove 420; in this embodiment, the above-mentioned product 100 is welded by a square thin sheet aluminum semi-finished product and an "S"-shaped thin sheet copper semi-finished product, and the welding area of the two is a square area, the bearing groove 410 is square, and one corner end thereof overlaps and communicates with the receiving groove 420. When the product 100 is placed in the bearing groove 410, the square thin sheet aluminum semi-finished product is embedded in the bearing groove 410, and the welding area is exactly located at the position where the bearing groove 410 and the receiving groove 420 overlap and communicate.

[0023] The scarring punch 300 is embedded in the receiving groove 420, and the upper surface of the scarring punch 300 protrudes from the bottom of the bearing groove 410. That is, when the product 100 is placed in the bearing groove 410, it is also placed on the scarring punch 300 and contacts the scarring punch 300. The upper surface of the scarring punch 300 is provided with a scarring protrusion 310 that is adapted to the size of the welding area of the product 100. When the product 100 is placed here, the overflowing weld scar of the product 100 contacts the scarring protrusion 310. The upper punch 200 is arranged above the scarring punch 300 and is controlled by an external device to press down on the scarring punch 300 or move away from the scarring punch 300. When working, the external equipment drives the upper punch head 200 to move toward the product 100, contacts and presses down, so that the scar pressing protrusion 310 squeezes the weld scar overflowing from the product 100, flattens it or presses the weld scar into the interior of the product 100. In this way, the weld scar can be flattened directly by the weld scar flattening jig without manual grinding, which not only reduces labor costs, but is also fast and efficient, greatly improving production efficiency.

[0024] The above-mentioned external device can be an automatic moving mechanism, such as a module that moves up and down under the control of a motor. The module includes a vertically arranged slide, a slider provided on the slide, and a motor that controls the slider to slide up and down. The slider extends downward, and the upper punch head 200 is provided on the slide, and is driven by the slider to move up and down, contacting and pressing the product 100 or moving upward away from the product 100. The above-mentioned external device can also be a mechanism that controls the up and down movement of the upper punch head 200 by a cylinder, or a punching machine, and the above-mentioned mechanism is provided on the punching machine. The present invention does not limit the external device, as long as the device can control the up and down movement of the upper punch head 200.

[0025] In one embodiment, the scar-pressing protrusion 310 includes a plurality of small protrusions, which enclose the shape of the welding area of the product 100. For example, when the welding area is rectangular, the corresponding small protrusions enclose a rectangular frame. In this way, the welding area is enclosed by a plurality of small protrusions. These small protrusions can press the overflowing weld scar into the product 100 or flatten it, so that the flattening purpose can be achieved without being pressed or a large pit being pressed out. In another embodiment, the scar-pressing protrusion 310 can also be set to a square, a circle, etc. according to the welding area. The shape of the small protrusion is not limited here, as long as it encloses the shape of the welding area.

The lower end of the scar flattening punch 300 is embedded in the groove 510 and is fixed in the groove 510 by a fixing pin. The product fixing seat 400 is fixed on the jig fixing seat 500. The jig fixing seat 500 is provided with a mounting hole, and is installed on an external device through the mounting hole.

[0027] In one embodiment, a stopper 430 extends from the product holder 400 toward the receiving groove 420. When the scarring punch 300 is inserted into the receiving groove 420, the stopper 430 contacts the upper surface of the scarring punch 300 to limit the position of the scarring punch 300. Furthermore, the stopper 430 contacts the scarring punch 300 near the edge, thereby achieving positional limitation while avoiding affecting the upper punch 200 from pressing the product 100 downward.

[0028] In one embodiment, a conducting groove is provided on the carrying groove 410, and the conducting groove includes a side wall groove 442 and a bottom groove 441 connected to the side wall groove 442. The bottom groove 441 is provided at the bottom of the carrying groove 410, and the side wall groove 442 is provided on the side wall of the carrying groove 410, so that the carrying groove 410 is connected to the outside world, and the side wall groove 442 is located at the position corresponding to the bottom groove 441. For example, the bottom groove 441 is provided in a "door" shape, and the bottom grooves 441 at both ends of the "door" are connected to the side wall grooves 442. When working, the product 100 is placed above the bottom groove 441 and is located in the carrying groove 410. In this way, when the product 100 needs to be taken out of the carrying groove 410, it can be directly flipped up by passing through the side wall groove 442 and contacting the lower end of the product 100 from the bottom groove 441. This not only saves materials but also makes it convenient to take.

[0029] The present invention also includes a weld scar flattening device including the above-mentioned weld scar flattening jig, including a base and a movable structure. The movable structure can be the above-mentioned automatic movable mechanism, or it can be a manual beer machine.
