Description

Technical Field

[0001] This utility model relates to the field of workpiece riveting and welding positioning, specifically an auxiliary positioning fixture for workpiece riveting and welding processing. Background Technology

[0002] Riveting is a type of electric welding. The typical method involves using a welding rod to penetrate the metal parts being welded. It's generally used for welding thicker metals. It's a process of connecting two or more metal parts using rivets or riveting fittings. Riveting is divided into cold riveting and hot riveting. Cold riveting uses rivets, while hot riveting is welding, which involves melting the joint between two metals at high temperatures. The welding materials can be metal or non-metal. Furthermore, depending on the riveting method, riveting can be classified into mixed riveting and other types. To improve the stability of the workpiece during the riveting process, auxiliary positioning fixtures are needed. Existing positioning fixtures are not convenient for simultaneously positioning two workpieces of different thicknesses at different angles, thus affecting their versatility. Therefore, it is necessary to provide a positioning fixture that facilitates simultaneous positioning of two workpieces of different thicknesses at different angles, enhancing its versatility. Additionally, existing positioning fixtures are not convenient for height adjustment as needed, affecting ease of use. Therefore, it is necessary to provide a positioning fixture that allows for height adjustment as needed, improving ease of use. Utility Model Content

Detailed Implementation

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

[0024] Example 1

[0025] Please see Figures 1-5 This utility model provides an auxiliary positioning fixture for workpiece riveting and welding, including a positioning component 100 and a lifting component 200;

[0026] The positioning component 100 includes a mounting plate 101, with a mounting column 102 fixedly connected to the upper end of the mounting plate 101. A crossbeam 103 is detachably inserted into the interior of the mounting column 102. Positioning plates 104 are detachably installed at both ends of the crossbeam 103. An anti-slip plate 105 is provided at the upper end of the positioning plate 104. A crossbeam 106 is detachably installed at the upper end of the mounting column 102. A fixing tube 107 is fixedly connected to both ends of the crossbeam 106. A positioning rod 108 is inserted into the interior of the fixing tube 107. A positioning block 109 is installed at the lower end of the positioning rod 108. A spherical groove 110 is opened at the lower end of the positioning rod 108. A universal ball 120 is fixedly connected to the upper end of the positioning block 109. The universal ball 120 is installed inside the spherical groove 110.

[0027] The lifting assembly 200 includes a receiving plate 201. Several inclined support legs 202 are fixedly connected to the side surface of the receiving plate 201. Telescopic legs 203 are inserted into the interior of each of the inclined support legs 202. Several pin holes 204 are equidistantly opened on the surface of the inclined support legs 202. A spring 205 is provided inside the upper end of the telescopic leg 203. A clip 206 is fixedly connected to the upper end of the spring 205. A self-locking universal wheel 207 is hinged to the lower end of the telescopic leg 203. A telescopic shaft 208 is detachably installed at the lower end of the receiving plate 201.

[0028] In one specific embodiment, the positioning component 100, in conjunction with the lifting component 200, not only facilitates multi-angle positioning operations on two workpieces of different thicknesses simultaneously, thereby enhancing the versatility of the positioning fixture, but also allows for easy adjustment of the height of the positioning fixture as needed, thus improving its ease of use. In use, controlling several telescopic legs 203 to extend and retract along the inside of the inclined support leg 202 adjusts the total length between the inclined support leg 202 and the telescopic legs 203. When the locking head 206 coincides with one of the pin holes 204 on the surface of the inclined support leg 202, the spring 205 ejects the locking head 206. This allows the clamping head 206 to engage inside one of the pin holes 204, thereby enabling the adjustment of the height of the positioning fixture. When positioning workpieces of different thicknesses, the two workpieces are first placed on the upper ends of the anti-slip plates 105 on both sides. The anti-slip plates 105 can increase the friction with the workpieces and improve stability. Then, the positioning rod 108 is controlled to descend along the fixed tube 107. The positioning plate 104, in conjunction with the positioning block 109, can clamp workpieces of different thicknesses. At the same time, the universal ball 120 rotates in the spherical groove 110, thereby adjusting the angle of the positioning block 109. Therefore, the workpieces can be clamped from different angles to enhance the versatility of the positioning fixture.

[0029] Please see Figure 2 and Figure 3 The side surface of the mounting plate 101 is provided with several slots 111, the upper end of the positioning plate 104 is provided with a mounting groove 112, and the anti-slip plate 105 is installed inside the mounting groove 112.

[0030] In one specific embodiment, the mounting groove 112 can improve the installation stability of the anti-slip plate 105, thereby improving the clamping and fastening of the workpiece.

[0031] Please see Figure 2 and Figure 3 Both ends of the crossbeam 103 are fixedly connected with plug rods 121. A plug groove 122 is provided on one side of the positioning plate 104, and the plug rods 121 are inserted into the plug groove 122.

[0032] In one specific embodiment, the plug rod 121 is inserted into the plug groove 122 to improve the ease of disassembly and replacement between the crossbeam 103 and the mounting column 102.

[0033] Please see Figure 2 and Figure 3 A screw tube 131 is fixedly connected to one side of the fixed tube 107, and a tightening bolt 132 is connected to the internal thread of the screw tube 131.

[0034] In one specific embodiment, the positioning rod 108 is clamped and fixed by rotating the clamping bolt 132 along the screw tube 131, thereby improving the installation and clamping stability of the positioning rod 108.

[0035] Please see Figure 2 and Figure 3 The lower end of the mounting column 102 is provided with a slot 141, and the crossbeam 103 is inserted into the slot 141.

[0036] In one specific embodiment, the crossbeam 103 is inserted into the slot 141, which facilitates the quick assembly and disassembly of the crossbeam 103, thereby improving the ease of assembly and disassembly of the various components of the positioning fixture.

[0037] Please see Figure 2 and Figure 3 The surface of the mounting plate 101 has several screw holes 151, and each screw hole 151 is threaded with a connecting bolt 152.

[0038] In one specific embodiment, the connecting bolt 152 is threaded into the screw hole 151, thereby enhancing the connection strength between the mounting plate 101 and the receiving plate 201, so as to improve the overall safety of the positioning operation.

[0039] Please see Figure 4 and Figure 5 The upper end of the receiving plate 201 is provided with a stabilizing groove 211. The mounting plate 101 is installed inside the stabilizing groove 211. Several locking blocks 212 are fixedly connected inside the stabilizing groove 211, and the locking blocks 212 are all locked inside the locking slot 111.

[0040] In one specific embodiment, the locking block 212 is engaged inside the slot 111 to prevent the mounting post 102 from rotating, thereby further improving the stability of the workpiece positioning and clamping.

[0041] Please see Figure 4 and Figure 5 A fixing rod 221 is fixedly connected to the lower end of the receiving plate 201, and a positioning hole 222 is opened at the upper end of the telescopic shaft 208, with the fixing rod 221 inserted into the positioning hole 222.

[0042] In one specific embodiment, the fixing rod 221 is inserted into the positioning hole 222, and together with the telescopic shaft 208, it can stabilize the height adjustment of the positioning fixture, thereby improving the safety of use.

[0043] Working principle: In use, several telescopic legs 203 are first controlled to telescopically move along the inside of the inclined support leg 202, thereby adjusting the total length between the inclined support leg 202 and the telescopic legs 203. When the clamping head 206 and one of the pin holes 204 on the surface of the inclined support leg 202 coincide, the spring 205 pops the clamping head 206 out, so that the clamping head 206 is engaged inside one of the pin holes 204, thereby adjusting the height of the positioning fixture. When positioning workpieces of different thicknesses, the two workpieces are first placed on the upper end of the anti-slip plates 105 on both sides. Then, the positioning rod 108 is controlled to descend along the fixed tube 107. The positioning plate 104 and the positioning block 109 can clamp workpieces of different thicknesses. At the same time, the universal ball 120 rotates in the spherical groove 110, thereby adjusting the angle of the positioning block 109, thus clamping the workpiece from different angles, thereby enhancing the versatility of the positioning fixture.
