Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: A welding equipment for metal parts production, such as... Figures 1-4 As shown, it includes a base 1; It also includes an annular support 2, an annular electric slide rail 3, an electric slider 4, a mounting plate 5, an electric push rod 6, and a welding gun 7; the annular support 2 and the annular electric slide rail 3 are welded on the base 1, with the annular support 2 located inside the annular electric slide rail 3; the electric slider 4 is slidably connected to the annular electric slide rail 3; the mounting plate 5 is connected to the electric slider 4; the electric push rod 6 is fixedly connected to the mounting plate 5; the welding gun 7 is fixedly connected to the telescopic end of the electric push rod 6; the welding gun 7 is located directly above the annular support 2.

[0021] It also includes an electric push rod 21 and an annular pressure plate 22; three electric push rods 21 are fixedly connected to the base 1; the telescopic ends of all the electric push rods 21 are fixedly connected to the annular pressure plate 22; the annular pressure plate 22 is located outside the annular support seat 2.

[0022] It also includes an electric push rod 31, a mounting bracket 32, and a motor 33; the electric push rod 31 is fixedly connected to the electric slider 4; the telescopic end of the electric push rod 31 is fixedly connected to the mounting bracket 32; the motor 33 is bolted to the mounting bracket 32; the output shaft of the motor 33 is fixedly connected to the mounting plate 5.

[0023] When welding, first place the annular steel ring on the annular receiving seat 2, then place the wire mesh on the steel ring, then control the electric push rod 6 to drive the roller welding gun 7 to descend, so that the roller welding wheel of the roller welding gun 7 presses the wire mesh on the steel ring, then control the annular electric sliding rail 3 to drive the electric sliding block 4 mounting plate 5, electric push rod 6 and roller welding gun 7 to make circular motion, so that the roller welding wheel of the roller welding gun 7 rolls on the steel ring, during the rolling process, the roller welding gun 7 is powered on, the roller welding gun 7 works to weld the wire mesh on the steel ring (the roller welding wheel acts as an electrode, when powered on, strong current passes through the electrode tip → through the wire mesh → reaches the steel ring, the metal in the contact area generates Joule heat due to its own resistance, quickly rises to a molten or plastic state, at the same time, under the continuous pressure of the roller welding wheel, the metal at the contact point of the wire mesh and the steel ring is fused or plastically deformed to form a welding point, so the wire mesh is welded on the steel ring), then control the electric push rod 6 to drive the roller welding gun 7 to move up and reset, and the welded wire mesh and steel ring can be taken off from the annular receiving seat 2; the device automatically makes the roller welding gun 7 roll on the steel ring to complete the welding, replacing the manual welding method in the prior art, and ensuring the consistency of the welding quality through precise and uniform motion control.

[0024] Even if the wire mesh and the steel ring surface are visually adhered, there are slight irregularities at the microscopic level, forming a small air gap, when only relying on the roller welding wheel of the roller welding gun 7 to press (such pressing is local and instantaneous), the roller welding wheel will press before the point is pressed, at the moment of contact at the point, a large current must flow through the narrow initial contact point, generating a strong electric arc, which is extremely easy to cause metal molten particles to splash, thereby polluting the workpiece surface and seriously affecting the workpiece quality; therefore, before welding, control the electric push rod 2 1 to drive the annular pressing plate 22 to descend, the annular pressing plate 22 moves down to pre-tightly press the wire mesh on the steel ring, and then welding is performed, so as to avoid strong electric arc and metal molten particles splashing to pollute the workpiece and affect the workpiece quality.

[0025] In order to increase the connection strength of the wire mesh and the steel ring, the device can also perform secondary welding on the wire mesh and the steel ring: after the wire mesh is welded at the top end of the steel ring, the control of the electric push rod two 21 drives the annular pressing plate 22 to continue to move downward, the annular pressing plate 22 presses the part of the wire mesh protruding from the steel ring, so that the part of the wire mesh protruding from the steel ring is deformed downward and adheres to the side of the steel ring, then the control of the motor one 33 drives the mounting plate one 5, the electric push rod one 6 and the roller welding gun 7 to rotate, so that the roller welding wheel of the roller welding gun 7 is perpendicular to the side of the steel ring, then the control of the electric push rod three 31 drives the mounting frame 32, the motor one 33, the mounting plate one 5, the electric push rod one 6 and the roller welding gun 7 to move, so that the roller welding wheel of the roller welding gun 7 adheres to the side of the steel ring, that is, the wire mesh is pressed tightly on the side of the steel ring, then the control of the annular electric sliding rail 3 drives the electric sliding block 4, the mounting plate one 5, the electric push rod one 6 and the roller welding gun 7 to do circular motion, so that the roller welding wheel of the roller welding gun 7 rolls on the side of the steel ring, during the rolling process, the roller welding gun 7 is powered, and the roller welding gun 7 works to weld the wire mesh on the side of the steel ring, so as to realize secondary welding and increase the connection strength of the wire mesh and the steel ring.

[0026] Example 2: based on example 1, as shown in Figures 1-4 The base 1 is connected with the mounting plate two 41; the mounting plate two 41 is connected with the lower limiting plate 42; the upper limiting plate 44 is placed on the lower limiting plate 42.

[0027] The positioning rod 43 is further included; the positioning rod 43 is welded in the middle of the lower limiting plate 42; the upper limiting plate 44 is inserted with the positioning rod 43.

[0028] In order to facilitate the upper limiting plate 44 to be sleeved on the positioning rod 43, the upper part of the positioning rod 43 is tapered.

[0029] In order to facilitate manual holding and moving of the upper limiting plate 44, a handle is arranged on the upper limiting plate 44.

[0030] The electric push rod four 45 is further included; three electric push rod fours 45 are fixedly connected to the base 1; the extension ends of all the electric push rod fours 45 are fixedly connected with the mounting plate two 41.

[0031] In order to monitor the size of the pushing force on the wire mesh, a pressure sensor is arranged between the extension end of the electric push rod four 45 and the mounting plate two 41.

[0032] The motor two 46 is further included; the motor two 46 is bolted in the middle of the mounting plate two 41; the output shaft of the motor two 46 is fixedly connected with the lower limiting plate 42.

[0033] When the welded wire mesh is relatively thin and bulky, after the wire mesh is placed on the steel ring, the part of the wire mesh on the inside of the steel ring is uneven, which leads to uneven wire mesh after welding and affects product quality; therefore, a lower limiting plate 42 is arranged on the inside of the annular receiving seat 2, when the steel ring is placed on the annular receiving seat 2, the upper end of the steel ring is flush with the upper side of the lower limiting plate 42, and then the upper limiting plate 44 is placed on the lower limiting plate 42, so that the wire mesh is flattened on the lower limiting plate 42 by the upper limiting plate 44, and then welding is performed, so as to avoid uneven wire mesh affecting product quality; the positioning rod 43 is arranged in the middle of the lower limiting plate 42, and the upper limiting plate 44 is sleeved on the positioning rod 43, so that the lower limiting plate 42 and the upper limiting plate 44 are always aligned, ensuring the flattening effect on the wire mesh.

[0034] In order to ensure the welding quality, during the production process, it is usually necessary to periodically check the welding quality, and the current operation is to transfer the product to a detection station for detection, which takes a long time and affects production; the present device can directly and quickly detect the welding quality without the need to transfer to a detection station for detection: after welding is completed, the annular pressing plate 22 is first kept to press the outer edge of the wire mesh downward, and then the electric push rod four 45 drives the mounting plate two 41, the lower limiting plate 42, the positioning rod 43 and the upper limiting plate 44 to move upward, the lower limiting plate 42 and the upper limiting plate 44 together drive the wire mesh to move upward, so that the wire mesh is pushed upward and tends to separate from the steel ring, the pushing force is monitored by the pressure sensor between the extension end of the electric push rod four 45 and the mounting plate two 41, and after a certain time, whether the wire mesh and the steel ring at the welded part are loose is observed, so as to detect the welding quality; after the detection is pushed, the motor two 46 can be controlled to drive the lower limiting plate 42, the positioning rod 43 and the upper limiting plate 44 to rotate, so that the lower limiting plate 42 and the upper limiting plate 44 rotate and move the wire mesh, so that the wire mesh tends to separate from the steel ring in the horizontal transverse direction, so as to detect the connection strength under the action of the horizontal pushing force, so as to improve the detection reliability.
