Description

Technical Field

[0001] This application relates to the field of welding fixture technology, specifically to a handheld positioning device for splicing welding. Background Technology

[0002] Before welding, the edges of the flat workpiece to be welded need to be aligned and fixed so that it can be sent to the welding station for welding. The positioning and fixing of the flat workpiece before welding is mainly to ensure the stability of the flat workpiece during the welding process, prevent welding deformation and weld position deviation, thereby ensuring the quality and performance of the welded product.

[0003] A laser welding fixture with back protection function, with announcement number CN204735853U, uses two positioning plates and fasteners to position two flat workpieces to be welded. When splicing and positioning the welding edges of the two flat workpieces, it is necessary to visually observe the position of the welding edges of the flat workpieces in the grooves. Positioning the welding edges of the flat workpieces is difficult and the work efficiency is low. Utility Model Content

[0004] To address the aforementioned issues, this application provides a handheld positioning device for splicing welding, which can quickly position flat workpieces, simplify the splicing positioning steps, and improve the welding efficiency of flat workpieces.

[0005] A handheld positioning device for splicing and welding flat workpieces includes a handheld clamping plate and a support base for supporting the welding of the flat workpieces. The support base can adsorb and fix the flat workpieces. The handheld clamping plate is used to fit against the support base.

[0006] The support base is provided with a clearance groove for placing the welding part of the flat workpiece;

[0007] The handheld card plate is provided with at least one positioning component, which can extend into the relief groove to restrict the position of the flat workpiece in the relief groove.

[0008] Preferably, the handheld card plate includes a mounting plate and a handheld component disposed on the mounting plate, wherein the positioning component is disposed on the side of the mounting plate.

[0009] More preferably, when there are at least two positioning components, the positioning components are located on the same side of the handheld card plate and extend to the side opposite to where the handheld component is located.

[0010] More preferably, the width of the positioning component is smaller than the width of the clearance groove.

[0011] Preferably, the support base includes a first support base and a second support base, and the first support base and the second support base form the relief groove. This allows the width of the relief groove to be adjusted according to welding requirements.

[0012] Preferably, the support base fixes the flat workpiece by magnetic attraction or vacuum adsorption. This allows for rapid fixation or release of the flat workpiece with a fast response time, and is also suitable for fixing irregularly shaped flat workpieces.

[0013] Preferably, the system further includes a magnetic platform, with the support base adsorbed onto the top of the magnetic platform. This allows for quick installation and removal of the support base.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application enables rapid splicing and positioning of flat workpieces by using a positioning component on a handheld card plate in conjunction with a clearance groove on a support base. The clearance groove prevents the flat workpiece from being welded to the support base. At the same time, the use of adsorption fixation method for rapid adsorption fixation or release of the flat workpiece greatly simplifies the splicing and positioning steps of the flat workpiece, shortens the splicing and positioning time of the flat workpiece, and improves production efficiency.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] See Figures 1 to 4 Further explanation of this application:

[0025] Combination Figure 1 A handheld positioning device for splicing and welding is used to position and splice flat workpieces. It includes a handheld clamping plate 20 and a support base 10 for supporting the welding of the flat workpieces. The support base 10 can adsorb and fix the flat workpieces. The handheld clamping plate 20 is used to fit the support base 10.

[0026] The support base 10 fixes the flat workpiece by magnetic attraction or vacuum adsorption. In an embodiment not shown, it can also be fixed by a pressure block and bolts. The adsorption fixing method has a fast response speed, which can quickly adsorb and fix the flat workpiece on the support base 10, and is convenient for fixing irregularly shaped flat workpieces (such as parallelograms, triangles, etc.). Compared with the existing positioning and fixing structure, the adsorption fixing method can avoid interference between the flat workpiece and the positioning and fixing structure.

[0027] The support base 10 is provided with a relief groove 100 for placing the welding part (welding edge) of the flat workpiece; the relief groove 100 can prevent the flat workpiece from being welded to the support base 10 during welding.

[0028] At least one positioning component 220 is detachably connected to the handheld card plate 20 so that the positioning component 220 of the corresponding width can be replaced according to the width of the relief groove 100. The positioning component 220 can extend into the relief groove 100 to limit the position of the flat workpiece in the relief groove 100. The positioning component 220 can be a positioning plate.

[0029] Compared to existing technologies, this application allows for the handheld card plate 20 to be held in contact with the surface of the support base 10. By extending the positioning component 220 into the clearance groove 100, one side of the positioning component 220 is made to fit against one side of the clearance groove 100. The other side of the positioning component 220 limits the positioning of the flat workpiece. After positioning, the positioned flat workpiece is fixedly moved out of the positioning component 220. The welding edge of another flat workpiece is aligned with the welding edge of the fixed flat workpiece and fixed, thus completing the splicing of the flat workpiece. This greatly reduces the difficulty of positioning and splicing flat workpieces and improves production efficiency.

[0030] The support base 10 can be equipped with an electromagnetic component, which can generate magnetic force to attract and fix or release the flat workpiece by external power supply or power failure; of course, it can also be provided with several adsorption holes, which can be connected to a vacuum device to achieve adsorption, fixation or release of the flat workpiece.

[0031] In this embodiment, the handheld card plate 20 includes a mounting plate 210 and a handheld component 230 disposed on the mounting plate 210. The positioning component 220 is disposed on the mounting plate 210. The mounting plate 210 is used to fit against the surface of the support base 10 and provide a support reference for the positioning component 220.

[0032] Combination Figure 2 In some embodiments, when there are at least two positioning components 220, all positioning components 220 are located on the same side of the handheld card plate 20. Figure 1 Both are located at the front end of the handheld card plate 20, and the handheld card plate 20 extends to the same side. Figure 1 (The middle part extends towards the bottom of the handheld card plate 20), that is, the positioning component 220 extends towards the opposite side where the handheld component 230 is located.

[0033] The width of the positioning component 220 is smaller than the width of the clearance groove 100. Preferably, the width of the clearance groove 100 is twice the width of the positioning component 220, in which case the weld joint of the spliced ​​flat workpiece is exactly in the middle of the clearance groove 100.

[0034] In some embodiments, the support base 10 is a split structure, wherein the support base 10 includes a first support base 110 and a second support base 120 disposed opposite to each other, and the first support base 110 and the second support base 120 form the clearance groove 100 so that the width of the clearance groove 100 can be adjusted as needed.

[0035] In one embodiment, a magnetic platform (not shown) is also included, on which the support base 10 is attached. The magnetic platform allows for quick installation or removal of the first support base 110 and the second support base 120; the magnetic platform may be a permanent magnet chuck.
