Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a multifunctional laser welding jig. Background Art

[0002] Laser welding is a welding process that uses a laser as a heat source. Its principle is that a high-energy laser beam is focused on the surface of the welding material, quickly heating and melting the welding part to form a weld seam. Before welding, the material needs to be placed on a positioning member, and the positioning member positions the material. Among them, the positioning member is fixed by a jig. The jig is composed of a positioning plate and a clamping block. A bolt is provided on the clamping block. When fixing, the positioning member is placed between the two clamping blocks, and by rotating the bolt, the bolt abuts against the side of the positioning member, thereby fixing the positioning member.

[0003] When in use, the material is placed in the positioning groove of the positioning member, and the material is welded by a laser welding machine. The laser beam moves along the direction of the positioning groove. When the laser beam moves beyond the positioning groove, the laser beam will irradiate the switch on the side of the positioning member, which will damage the switch and seriously cause a short circuit in the internal circuit. Therefore, the present application provides a multifunctional laser welding jig to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a multifunctional laser welding jig to solve the problem that when the laser beam moves beyond the positioning groove, the laser beam will irradiate the switch on the side of the positioning member, which will damage the switch and seriously cause a short circuit in the internal circuit.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A multifunctional laser welding jig includes a positioning plate and two clamping blocks fixed on the top of the positioning plate. Bolts are threadedly connected to the opposite surfaces of the two clamping blocks for fixing a positioning member placed inside the clamping blocks. It further includes:

[0007] A protection component. The protection component includes a protection block provided on the clamping block. When in use, the side surface of the protection block fits against the side surface of the positioning member, and an adaptation groove adapted to the positioning groove on the top of the positioning member is opened on the top of the protection block.

[0008] Preferably, a connecting block is fixed on the side surface of the protection block, a fixing block is fixed on the top of the clamping block, and a screw rod is rotatably connected to the surface of the fixing block. The connecting block is threadedly connected to the surface of the screw rod.

[0009] Preferably, a sphere is provided at one end of the screw rod away from the positioning member, and anti-slip stripes are provided on the surface of the sphere.

[0010] Preferably, a replacement block is provided on the inner wall of the adaptation slot, and the shape of the replacement block is adapted to the shape of the adaptation slot.

[0011] Preferably, a magnetic block is inlaid on the inner wall of the adaptation slot. During use, the replacement block is fixed in the adaptation slot by the magnetic force of the magnetic block.

[0012] Preferably, a positioning hole is provided at the bottom of the adaptation slot, and a positioning block is fixed at the bottom of the replacement block. During use, the positioning block is movably inserted into the positioning hole.

[0013] Preferably, the bottom of the positioning block is provided with a curved surface.

[0014] Preferably, a groove is provided on one side of the protection block close to the positioning member, and a curved panel is fixed on the side of the groove away from the positioning member. During use, the curved panel fits on the side surface of the positioning member.

[0015] Preferably, a limiting plate is fixed on the side of the groove away from the positioning member, and the limiting plate is located below the curved panel.

[0016] Preferably, the limiting plate is provided with a curved surface.

[0017] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0018] In the above solution, by providing a protection component, during use, the protection block fits on the side surface of the positioning member, and the protection block is located above the switch of the positioning member. When the laser beam moves out of the positioning slot of the positioning member, the laser beam will irradiate on the protection block, thereby protecting the switch and avoiding damage to the switch. Secondly, the replacement block provided in the adaptation slot can be replaced when the laser irradiates on the replacement block multiple times, and it is not necessary to replace the entire protection block, achieving the effect of saving resources.

[0019] By providing a curved panel, the curved panel has a certain elasticity. After the protection block fits on the surface of the positioning member, the curved panel will tightly fit on the surface of the positioning member, reducing the gap between the curved panel and the positioning member, further preventing the laser beam from irradiating on the switch, and improving the protection ability of the switch.

[0032] As Figures 1-5 shown, an embodiment of the present utility model provides a multifunctional laser welding fixture, including a positioning plate 1 and two clamping blocks 2 fixed on the top of the positioning plate 1. Bolts are threadedly connected to the opposite surfaces of the two clamping blocks 2 for fixing a positioning member 3 placed inside the clamping blocks 2. A switch is provided on the side surface of the positioning member 3. It further includes:

[0033] A protection component 4, the protection component 4 includes a protection block 41 provided on the clamping block 2. During use, the side surface of the protection block 41 fits against the side surface of the positioning member 3. The protection block 41 can be made of stainless steel. An adaptation groove 42 adapted to the positioning groove at the top of the positioning member 3 is provided at the top of the protection block 41.

[0034] As Figure 2 shown, in this embodiment, a connecting block 48 is fixed to the side surface of the protection block 41, a fixing block 47 is fixed to the top of the clamping block 2, a screw rod 49 is rotatably connected to the surface of the fixing block 47, the connecting block 48 is threadedly connected to the surface of the screw rod. Two rings are fixedly sleeved on the surface of the screw rod 49, and the two rings are located on both sides of the fixing block 47. Through the positioning of the screw rod 49 by the rings, when rotating, the screw rod 49 can only rotate within the fixing block 47 and will not undergo axial displacement.

[0035] As Figure 2 shown, in this embodiment, a sphere is provided at one end of the screw rod 49 away from the positioning member 3. Anti-slip stripes are provided on the surface of the sphere. The sphere is fixed to the end of the ring. By means of the sphere, the contact surface with the hand is increased, and the anti-slip stripes are for increasing the friction with the fingers, making it more labor-saving to rotate the screw rod 49.

[0036] As Figures 3-5 shown, in this embodiment, a replacement block 43 is provided on the inner wall of the adaptation groove 42. The shape of the replacement block 43 is adapted to the shape of the adaptation groove 42. The replacement block 43 is a consumable. When the replacement block 43 is worn out, the replacement block 43 is replaced, and there is no need to replace the entire protection block 41, achieving the purpose of saving resources.

[0037] As Figure 4As shown, in this embodiment, a magnetic block 44 is inlaid on the inner wall of the fitting groove 42. During use, the replacement block 43 is fixed in the fitting groove 42 by the magnetic force of the magnetic block 44. Fixing the replacement block 43 in the way of using the magnetic block 44 is more convenient when replacing the replacement block 43.

[0038] As Figure 3 and Figure 4 shown, in this embodiment, a positioning hole 45 is opened at the bottom of the fitting groove 42, and a positioning block 46 is fixed at the bottom of the replacement block 43. During use, the positioning block 46 is movably inserted into the positioning hole 45. After the positioning block 46 is inserted into the positioning hole 45, the positioning of the replacement block 43 is realized, avoiding the horizontal movement of the replacement block 43 and making the replacement block 43 more stable after being fixed.

[0039] As Figure 3 and Figure 4 shown, in this embodiment, the bottom of the positioning block 46 is provided with a curved surface, and the curved surface can guide the positioning block 46, making it easier for the positioning block 46 to slide into the positioning hole 45.

[0040] As Figure 3 shown, in this embodiment, a groove 5 is opened on the side of the protective block 41 close to the positioning member 3, and a curved panel 6 is fixed on the side of the groove 5 away from the positioning member 3. During use, the curved panel 6 fits on the side of the positioning member 3. By closely fitting the curved panel 6 on the side of the positioning member 3, the laser beam is further prevented from irradiating on the switch, further improving the protection effect on the switch.

[0041] As Figure 3 shown, in this embodiment, a limiting plate 7 is fixed on the side of the groove 5 away from the positioning member 3. The limiting plate 7 is located below the curved panel 6. The limiting plate 7 limits the curved panel 6, preventing the curved panel 6 from rebounding to the horizontal state. When the curved panel 6 is in the bent state, it makes it easier for the curved panel 6 to closely fit on the side of the positioning member 3.

[0042] As Figure 3 shown, in this embodiment, the limiting plate 7 is provided with a curved surface, and the limiting plate 7 is adapted to the shape of the curved panel 6, reducing the damage to the limiting plate 7 during limiting.

[0043] Working principle: Before use, fix the positioning plate 1 on the working table of the laser welding machine, place the positioning member 3 between the clamping blocks 2, and fix the positioning member 3 with the bolts on the side of the clamping blocks 2. Then rotate the screw 49 on the fixing block 47, and the screw 49 drives the connecting block 48 to move towards the positioning member 3 until the protective block 41 fits on the side of the positioning member 3. At the same time, the curved panel 6 in the groove 5 also fits on the side of the positioning member 3;

[0044] During welding, the material is placed in the positioning groove of the positioning member 3, and the material is welded by a laser welding machine. When the laser beam exceeds the positioning groove, the laser beam will irradiate on the replacement block 43, and the laser beam will not irradiate on the switch of the positioning member 3, realizing the protection of the switch;

[0045] After being used multiple times, the replacement block 43 is severely burned. At this time, the replacement block 43 is pulled out upward, a new replacement block 43 is taken, the positioning block 46 at the bottom of the body block is inserted into the positioning hole 45, and the replacement block 43 is placed in the fitting groove 42 again. At this time, the magnetic force of the magnet 44 fixes the replacement block 43, and then it can be used continuously.

[0046] The present utility model covers any alternatives, modifications, equivalent methods and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions.

[0047] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
