Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a buffer-type welding nail placing fixture for welding. Background Art

[0002] A fixture is a device used to fix the object to be processed in the process of mechanical manufacturing so that it occupies the correct position to accept construction or welding. In particular, it can be used to quickly, conveniently and safely install welding studs and products during the welding process. During welding commissioning and production, the welding fixture has no buffer, and the clamping mechanism (such as strong magnetism) of the fixture has a great impact on the clamp when it is clamped or opened. There is often damage to the welding fixture, or the impact force when the fixture is closed causes the deformation of the product or welding studs, affecting the product quality. However, if the clamping mechanism is not used, the product and welding studs cannot be fixed, which leads to the inability to position the welding of multiple points, slow processing efficiency, and low quality of welding products. Utility Model Content

[0018] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0019] Please refer to the attached Figure 1 -Attached Figure 3As shown, a buffer-type welding nail placement fixture for welding includes a clamp seat 1 and a clamp seat 2 which are hinged to each other, and the surfaces of the clamp seat 1 and the clamp seat 2 which are in contact with each other are provided with a strong magnet 11, so that when the clamp seat 1 and the clamp seat 2 are closed, they are used to press the product and the welding nail 9, which is convenient for welding in the subsequent process. The clamp seat 2 is provided with a through groove 3, and the through groove 3 is used to place a fixing block 4 with the welding nail 9, and the fixing block 4 is used to fix the position of the welding nail 9. The upper surface of the fixing block 4 is provided with a groove 5 for placing the welding nail 9 , the size of the groove 5 is adapted to the size of the welding nail 9. In order to facilitate the subsequent welding of the welding nail 9 and the product, after the welding nail 9 is placed in the groove 5, the surface of the welding nail 9 is slightly higher than the groove 5. The subsequent laser welding is performed on the protruding part of the welding nail 9 and the product, and the product to be welded is placed on the surface of the clamp seat 2; preferably, in order to fix the product and prevent the product from shifting when closed, the clamp seat 2 is symmetrically provided with a limiting boss 10 slightly higher than the upper surface of the clamp seat 2, and the product is placed between the two limiting bosses 10;

[0020] The impact force generated by the sudden closing of the clamp seat 1 and the clamp seat 2 under the action of the strong magnet 11 is relatively large, which will cause the welding nail 9 to push out a bulge the size of the welding nail on the surface of the product, thereby affecting the product quality. Therefore, a buffer mechanism is provided on the clamp seat 2, that is, a buffer hole 6 connected to the groove 5 is also provided in the fixing block 4, and a probe 8 is provided in the buffer hole 6, and the top of the probe 8 extends into the groove 5; specifically, the welding nail 9 is first placed in the groove 5, and then the product is placed above the welding nail 9, that is, on the surface of the clamp seat 2; when the welding nail 9 is placed, the probe 8 pushes the welding nail 9 out of a part of the groove 5, so that when the clamp seat 1 and the clamp seat 2 are closed, the welding nail 9 compresses the probe 8 downward in the groove 5, and the elasticity of the probe 8 has a certain buffering effect on the welding nail 9 and the product, preventing the deformation of the product welding part under the action of the welding nail 9, and ensuring that the welding nail 9 is in full contact with the product surface for easy welding.

[0021] The fixing block 4 is a consumable, because when welding the welding nail 9, laser welding will inevitably cause certain losses to the fixing block 4, that is, the groove 5. Therefore, the fixing block 4 can be detachably placed in the through groove 3, so that it can be replaced at any time. The through groove 3 is symmetrically provided with card grooves 14 on both sides, and the fixing block 4 is provided with card blocks 7 that cooperate with the card grooves 14 on both sides. The fixing block 4 detachably fixes the welding nail 9 on the clamp seat 2 2 through the cooperation of the card block 7 and the card groove 14.

[0022] In the above embodiments, please refer to the attached Figure 2 As shown, preferably, notches are symmetrically provided on both sides of the groove 5, and the welding nails 9 are conveniently taken in and placed through the notches.

[0023] According to actual production needs, the bottom of the buffer hole 6 is threadedly connected with a limiting bolt, and the position height of the probe 8 is adjusted by the limiting bolt, thereby adjusting the distance by which the top end of the probe 8 pushes the welding nail 9 out, which is easy to operate.

[0024] Please adopt the monthly attachment Figure 2 and attached Figure 3 As shown, when the clamp seat 1 and the clamp seat 2 are completely closed, the entire clamp seat is turned over, and the laser welding head extends from the other end of the through slot 3 to weld the welding pin 9 and the product. Because the laser welding head has a certain tilt angle when welding, in order to facilitate welding, the cross-section of the side of the fixing block 4 is trapezoidal, which is easy to operate, ensures welding quality and improves work efficiency.

[0025] In the above embodiment, preferably, a positioning pin 12 is provided on the surface of the clamp seat 2, and a positioning hole 13 cooperating with the positioning pin 12 is provided on the surface of the clamp seat 1. When closed, the positioning pin 12 and the positioning hole 13 play a certain guiding and positioning role on the clamp seat 1 to avoid displacement when the clamp seat 1 is closed.

[0026] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
