Description

Technical Field

[0001] The utility model relates to die benchmark positioning, and more specifically, to a scribing auxiliary tool for quickly improving the die benchmark positioning accuracy. Background Technique

[0002] With the continuous development of welding automation technology, more and more automatic welding robots are used to weld workpieces to be welded in the existing welding process. Specifically, the die is first fixed by setting up the die, then the automatic welding robot is adjusted and tested, and finally the automatic welding robot can weld the workpieces to be welded and welding connectors on the die together.

[0003] In actual production or application, most of the products to be welded are only installed on the platform manually, and then the robot performs fixed-point welding on the products. During the welding process, it is necessary to continuously adjust the placement orientation (including position and angle) of the products manually. However, adjusting the products manually cannot accurately adjust the products to a suitable welding orientation, thereby affecting the welding quality.

[0004] Regarding the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

[0005] Regarding the problems in the related art, the utility model provides a scribing auxiliary tool for quickly improving the die benchmark positioning accuracy to overcome the above-mentioned technical problems existing in the existing related art.

[0006] Therefore, the specific technical solution adopted by the utility model is as follows:

[0007] A scribing auxiliary tool for quickly improving the die benchmark positioning accuracy includes a base. On the base, turnover boxes are symmetrically welded. A turnover mechanism is arranged inside the turnover boxes. The turnover mechanism includes a turnover cavity opened inside the turnover boxes. A turnover shaft rod is rotatably connected inside the turnover cavity. A turnover gear is fixedly connected to the turnover shaft rod. A moving block is slidably connected to the bottom end of the turnover cavity far from the turnover shaft rod. A strip tooth is fixedly connected to the moving block. The strip tooth meshes with the turnover gear. A groove is opened on the bottom end of the turnover box. An electric telescopic rod is fixedly installed on the side wall of the groove. The output end of the electric telescopic rod is fixedly connected to a connecting block. The top end of the connecting block extends into the turnover cavity and is fixedly connected to the moving block. One end of the turnover shaft rod far from the turnover gear extends outside the turnover box and is fixedly connected to a platform plate. A clamping mechanism is arranged inside the platform plate.

[0008] Further, in order to fix the product to be welded on the platform plate, the clamping mechanism includes clamping cavities that are equally spaced and staggered inside the platform plate. A reciprocating motor is fixedly installed at the bottom end inside the clamping cavity. The output end of the reciprocating motor is connected to a lead screw through a coupling, and a clamping block is threadedly connected to the lead screw.

[0009] Further, in order to position the product to be welded, the platform plate is sequentially installed with a first X-axis positioning member, a second X-axis positioning member, and a Y-axis positioning member.

[0010] Further, in order to enable the moving block to slide stably in the flipping cavity, sliding grooves are opened at both ends of the inner surface of the flipping cavity. Sliding blocks are welded to both ends of the outer surface of the moving block, and the sliding blocks are slidably connected to the sliding grooves.

[0011] Further, in order to prevent the clamping block from damaging the product to be welded, the top end of the clamping block extends outside the platform plate and is fixedly connected to a rubber pad.

[0012] Further, in order to facilitate the movement of the moving block, moving holes are opened on both sides of the outer surface of the flipping box. The moving holes communicate with the flipping cavity and match the moving block.

[0013] Further, in order to facilitate the installation and disassembly of the base, mounting holes are symmetrically opened at one end of the base away from the flipping box.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The product to be welded is placed on the platform plate. The X-axis reference line corresponding to the product to be welded is fitted with the first X-axis positioning member and the second X-axis positioning member, and the Y-axis reference line corresponding to the product to be welded is fitted with the Y-axis positioning member, which can effectively improve the positioning accuracy of the product to be welded.

[0016] 2. After the product to be welded is positioned, the reciprocating motor works. The reciprocating motor drives the lead screw to rotate in the clamping cavity and makes the clamping block slide on the platform plate. The sliding of the clamping block can fix the product to be welded firmly on the platform plate, preventing the product to be welded from falling during the flipping process of the platform plate and affecting the welding efficiency of the product to be welded.

[0017] 3. The product to be welded is fixed on the platform plate. The automatic welding robot can perform spot welding on the product to be welded. At the same time, by operating the electric telescopic rod, the electric telescopic rod itself expands and contracts, causing the connecting block to move within the groove. The movement of the connecting block causes the moving block to move synchronously within the flipping cavity, and the strip teeth move accordingly. Through the engagement of the strip teeth with the flipping gear, the movement of the strip teeth causes the flipping gear to rotate, and the flipping shaft rod rotates synchronously with the flipping gear. The rotation of the flipping shaft rod causes the platform plate to flip. During the flipping process, the automatic welding robot can perform welding on the product to be welded installed on the platform plate from multiple angles, further improving the welding quality.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] According to an embodiment of the present invention, there is provided a scribing auxiliary tool for quickly improving the reference positioning accuracy of a mold.

[0027] Embodiment 1;

[0028] As Figures 1-3 shown, the scribing auxiliary tool for quickly improving the reference positioning accuracy of a mold according to an embodiment of the present invention includes a base 1. Symmetrically welded on the base 1 are turning boxes 3. At one end of the base 1 away from the turning boxes 3, installation holes 2 are symmetrically provided. Threadedly connected in the installation holes 2 are installation bolts, which facilitate the installation and disassembly of the base 1. Inside the turning box 3 is provided a turning mechanism. The turning mechanism includes a turning cavity 4 opened inside the turning box 3. Rotatably connected in the turning cavity 4 is a turning shaft rod 5. Fixedly connected to the turning shaft rod 5 is a turning gear 6. At the bottom end inside the turning cavity 4 away from the turning shaft rod 5, a moving block 7 is slidably connected. In order to make the moving block 7 slide stably in the turning cavity 4, sliding grooves 9 are opened at both ends of the inner surface of the turning cavity 4. Welded to both ends of the outer surface of the moving block 7 are sliding blocks 8. The sliding blocks 8 are slidably connected with the sliding grooves 9. Fixedly connected to the moving block 7 is a bar tooth 10. The bar tooth 10 meshes with the turning gear 6. On both sides of the outer surface of the turning box 3 are opened moving holes 11. The moving holes 11 communicate with the turning cavity 4 and match with the moving block 7. At the bottom end of the turning box 3 is opened a groove 12. Fixedly installed on the side wall of the groove 12 is an electric telescopic rod 13. The electric telescopic rod 13 is electrically connected to the control system of the automatic welding robot. The output end of the electric telescopic rod 13 is fixedly connected to a connecting block 14. The top end of the connecting block 14 extends into the turning cavity 4 and is fixedly connected to the moving block 7. The end of the turning shaft rod 5 away from the turning gear 6 extends outside the turning box 3 and is fixedly connected to a platform plate 15. The product to be welded is fixed on the platform plate 15. The automatic welding robot can perform fixed-point welding on the product to be welded. At the same time, by making the electric telescopic rod 13 work, the electric telescopic rod 13 itself expands and contracts, causing the connecting block 14 to move in the groove 12. The movement of the connecting block 14 causes the moving block 7 to move synchronously in the turning cavity 4 and makes the bar tooth 10 move accordingly. Through the meshing of the bar tooth 10 with the turning gear 6, the movement of the bar tooth 10 causes the turning gear 6 to rotate and makes the turning shaft rod 5 rotate synchronously with the turning gear 6. The rotation of the turning shaft rod 5 causes the platform plate 15 to turn. During the turning process, the automatic welding robot can perform multi-angle welding on the product to be welded installed on the platform plate 15, further improving the welding quality.

[0029] Example 2

[0030] Please refer to Figure 1 and Figure 4 In order to fix the product to be welded on the platform plate 15, a clamping mechanism is provided inside the platform plate 15. The clamping mechanism includes clamping cavities 16 that are equidistantly and staggeredly distributed inside the platform plate 15. A reciprocating motor 17 is fixedly installed on the bottom end inside the clamping cavity 16. The reciprocating motor 17 is wirelessly connected to the control system of the automatic welding robot. The output end of the reciprocating motor 17 is connected to a lead screw 18 through a coupling. A clamping block 19 is threadedly connected to the lead screw 18. In order to prevent the clamping block 19 from damaging the product to be welded, the top end of the clamping block 19 extends outside the platform plate 15 and is fixedly connected to a rubber pad 20. After the positioning of the product to be welded is completed, the reciprocating motor 17 operates. The reciprocating motor 17 drives the lead screw 18 to rotate inside the clamping cavity 16 and makes the clamping block 19 slide on the platform plate 15. The sliding of the clamping block 19 can firmly fix the product to be welded on the platform plate 15, preventing the product to be welded from falling during the flipping process of the platform plate 15 and affecting the welding efficiency of the product to be welded.

[0031] Example 3

[0032] Please refer to Figure 1 In order to position the product to be welded, the platform plate 15 is successively installed with a first X-axis positioning member 21, a second X-axis positioning member 22, and a Y-axis positioning member 23. The first X-axis positioning member 21 and the second X-axis positioning member 22 are arranged on the X-axis reference line of the installation station of the product to be welded, and the Y-axis positioning member 23 is arranged on the Y-axis reference line of the installation station of the product to be welded. The product to be welded is placed on the platform plate 15. Aligning the X-axis reference line corresponding to the product to be welded with the first X-axis positioning member 21 and the second X-axis positioning member 22, and aligning the Y-axis reference line corresponding to the product to be welded with the Y-axis positioning member 23 can effectively improve the positioning accuracy of the product to be welded.

[0033] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0034] In actual application, first, the product to be welded is placed on the platform plate 15. The X-axis reference line corresponding to the product to be welded is fitted to the first X-axis positioning member 21 and the second X-axis positioning member 22, and the Y-axis reference line corresponding to the product to be welded is fitted to the Y-axis positioning member 23. After the positioning of the product to be welded is completed, secondly, the reciprocating motor 17 is operated. The reciprocating motor 17 drives the lead screw 18 to rotate in the clamping cavity 16, and the clamping block 19 slides on the platform plate 15. The sliding of the clamping block 19 can fix the product to be welded firmly on the platform plate 15, preventing the product to be welded from falling during the flipping process of the platform plate 15. Then, the automatic welding robot performs spot welding on the product to be welded. At the same time, by operating the electric telescopic rod 13, the electric telescopic rod 13 expands and contracts itself, causing the connecting block 14 to move in the groove 12. The movement of the connecting block 14 causes the moving block 7 to move synchronously in the flipping cavity 4, and the strip teeth 10 move accordingly. Through the engagement of the strip teeth 10 with the flipping gear 6, the movement of the strip teeth 10 causes the flipping gear 6 to rotate, and the flipping shaft rod 5 rotates synchronously with the flipping gear 6. The rotation of the flipping shaft rod 5 causes the platform plate 15 to flip. During the flipping process, the automatic welding robot can weld the product to be welded installed on the platform plate 15 at multiple angles, further improving the welding quality.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
