Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding tooling, in particular to a lobe welding tooling device. Background Technique
[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. Laser welding is an important aspect of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.
[0003] When laser welding lobes on the surface of a workpiece, in order to ensure the accuracy of the lobe position, it is usually necessary to use a fixing tooling to press the lobe tightly on the surface of the workpiece to avoid the lobe position shifting before and during welding. The existing fixing tooling usually only uses structures such as bolt pressing plates to cooperate to press the lobe tightly. However, in the actual production process, the arcs of the lobes of different styles of products will be different. When using a flat pressing plate to press tightly in a small range, other parts and edges of the lobe are prone to warping, which will affect the welding effect. Therefore, different types of pressing plates need to be customized, but this also increases the cost. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a lobe welding tooling device, which solves the problems that the use of a general fixing structure has a poor fixing effect and affects the welding effect, while customizing the fixing structure increases the cost.
[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A lobe welding tooling device includes a base for placing the workpiece to be welded, and a fixing mechanism is installed on the base to press the lobe tightly against the side of the workpiece to be welded. A flexible structure is arranged in the fixing mechanism to avoid damaging the lobe.
[0006] The fixing mechanism includes a main pressing plate for pressing the middle part of the lobe, and side pressing strips elastically arranged on both sides of the main pressing plate for pressing both sides of the lobe. An auxiliary pressing plate adapted to the arc of the lobe is also elastically arranged on the main pressing plate.
[0007] Preferably, the bottom of the auxiliary pressing plate is elastically connected to the top of the main pressing plate through a torsion spring, and both sides of the main pressing plate are fixedly connected to the side pressing strips through elastic plates.
[0008] Preferably, rubber pads for avoiding damaging the lobe are arranged on one side of the auxiliary pressing plate and the main pressing plate close to the lobe.
[0009] Preferably, the fixing mechanism further includes a mounting seat fixedly connected to the base. Two rows of guide rods are horizontally and slidably penetrated through the lower layer inside the mounting seat and connected up and down, and one end of the guide rod is fixedly connected to the surface of the main pressing plate.
[0010] Preferably, a tightening bolt is horizontally and threadedly penetrated through the upper layer inside the mounting seat, and one end of the tightening bolt is rotatably connected to the surface of the main pressing plate.
[0011] Preferably, the tightening bolt includes a main screw rod threadedly penetrated through the mounting seat. A screw sleeve is rotatably sleeved at one end of the main screw rod close to the screw head. The external thread of the screw sleeve is threadedly connected to the inner side of the mounting seat and the thread rotation direction is opposite to that of the main screw rod. A plurality of rubber bump points are embedded in the head end face of the screw sleeve.
[0012] Beneficial effects
[0013] The utility model provides a lobe welding tooling device. Compared with the prior art, the following beneficial effects are achieved:
[0014] 1. For this lobe welding tooling device, by setting the main pressing plate to mainly press the lobe, and the side pressing strip and the auxiliary pressing plate cooperate to assist in pressing the remaining arc section and the side of the lobe, the lobe can be better stressed and kept firmly pressed on the surface of the workpiece to be welded, without displacement during the laser welding process, ensuring the welding quality.
[0015] 2. For this lobe welding tooling device, by setting the bolts on the inner and outer sides, the main screw rod is responsible for screwing and pushing the main pressing plate to press the lobe. The screw sleeve can rotate in the reverse direction and slide out in the reverse direction to abut against the head of the main screw rod. The reverse spiral and the resistance applied by the rubber bump points make the main screw rod more stable during the working process and not easily loosen, resulting in the lobe not being tightly pressed.

Specific Embodiments
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] The present utility model provides two technical solutions:
[0023] Figures 1-3 The first embodiment is shown: A lobe welding tooling device includes a base 2 for placing the workpiece 1 to be welded. A fixing mechanism 4 for pressing the lobe 3 against the side of the workpiece 1 to be welded is installed on the base 2. There are 24 groups of the fixing mechanism 4 arranged in a circle, corresponding to fixing 24 lobes 3. A flexible structure for preventing damage to the lobe 3 is provided inside the fixing mechanism 4;
[0024] The fixing mechanism 4 includes a main pressing plate 41 for pressing the middle part of the lobe 3, and side pressing strips 42 arranged on both sides of the main pressing plate 41 for pressing both sides of the lobe 3. The side pressing strips 42 are of a ductile structure to facilitate matching the arc of the lobe 3. An auxiliary pressing plate 43 for adapting to the arc of the lobe 3 is elastically provided on the main pressing plate 41. The bottom of the auxiliary pressing plate 43 and the top of the main pressing plate 41 are elastically connected by a torsion spring. Both sides of the main pressing plate 41 are fixedly connected to the side pressing strips 42 through elastic plates 48. Rubber pads 44 for preventing damage to the lobe 3 are provided on both the auxiliary pressing plate 43 and the side of the main pressing plate 41 close to the lobe 3.
[0025] The fixing mechanism 4 further includes a mounting seat 45 fixedly connected to the base 2. Two upper and lower rows of guide rods 46 are horizontally slidably penetrated through the lower layer inside the mounting seat 45 and connected, and one end of the guide rod 46 is fixedly connected to the surface of the main pressing plate 41. An adjusting bolt 47 is horizontally threaded through the upper layer inside the mounting seat 45, and one end of the adjusting bolt 47 is rotatably connected to the surface of the main pressing plate 41.
[0026] By setting the main pressing plate 41 to mainly press the lobe 3, and the side pressing strips 42 and the auxiliary pressing plate 43 cooperate to assist in pressing the remaining arc section and the side of the lobe 3, the lobe 3 can be better stressed and be firmly pressed on the surface of the workpiece 1 to be welded in an all-round and stable manner without displacement during the laser welding process, ensuring the welding quality.
[0027] Figure 4The second embodiment is shown. The main difference from the first embodiment is that the tightening bolt 47 includes a main screw rod 471 whose thread penetrates through the mounting seat 45. One end of the outer part of the main screw rod 471 near the screw head is rotatably sleeved with a screw sleeve 472. The external thread of the screw sleeve 472 is threadedly connected to the inner side of the mounting seat 45 and the thread rotation direction is opposite to that of the main screw rod 471. A plurality of rubber bumps 473 are embedded in the head end face of the screw sleeve 472.
[0028] By providing bolts on both the inner and outer sides, the main screw rod 471 is responsible for screwing and pushing the main pressing plate 41 to press the lobe 3. The screw sleeve 472 can rotate in the reverse direction and slide out reversely to abut against the head of the main screw rod 471. The reverse spiral and the resistance applied by the rubber bumps 473 make the main screw rod 471 more stable during operation and not easily loosen, resulting in the lobe 3 not being tightly pressed.
[0029] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0030] During use, the lobe 3 is attached to a specified position on the side of the workpiece 1 to be welded. Then, the main screw rod 471 is rotated to push forward structures such as the main pressing plate 41, the side pressing strip 42, the auxiliary pressing plate 43, and the rubber pad 44. The main pressing plate 41 presses the flat section of the lower half of the lobe 3, and the side pressing strip 42 and the auxiliary pressing plate 43 elastically press the side and the arc section of the upper half of the lobe 3 to tightly press the lobe 3 in all aspects. Then, the screw sleeve 472 is rotated in the reverse direction to rotate out reversely and abut against the tightening bolt 47 to limit its rotation. After that, the base 2 can be rotated to drive the entire mechanism to rotate intermittently at a fixed angle to perform laser welding on a circle of lobes 3.
[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to this process, method, article or device.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
