Description

Technical Field

[0001] The invention relates to the technical field of welding auxiliary equipment, and in particular to a welding equipment auxiliary device for mechanical manufacturing. Background Art

[0002] Welding equipment is a tool used to connect materials in mechanical manufacturing and related fields. It firmly connects different metal or non-metal materials by generating high temperature, high pressure or specific energy forms. Welding equipment is of great significance. In industrial production, it can efficiently complete the connection task of complex structures and ensure the strength and sealing of products. For mechanical manufacturing, welding equipment is a key means to realize the assembly of parts, which helps to improve production efficiency, reduce production costs, and ensure product quality and reliability, providing solid technical support for the development of various industries.

[0003] Welding equipment auxiliary equipment is equipment that plays an auxiliary role in the welding process, including fixtures, positioners, manipulators, etc. They improve welding quality and efficiency, expand the application scope of welding equipment, and ensure the smooth progress of welding work by fixing weldments, changing weldment positions, supporting and moving welding equipment, etc., which is very important for welding production.

[0004] In the field of mechanical manufacturing, large-area steel plates are often required for production and manufacturing. In the actual production process, the large-area steel plates directly produced are difficult to transport due to their weight and volume. Therefore, most manufacturers form large-size steel plates by splicing and welding standard-sized steel plates. However, in the welding process, most of them directly place two steel plates on the welding surface for welding. Since the positions of the steel plates are not fixed, the positions of the steel plates are prone to shift during the welding process, which leads to the butt weld of the two steel plates being too large or even causing the butt weld of the two steel plates to be uneven, thereby affecting the welding quality of the steel plates. It is inconvenient for workers in actual operation. Therefore, an auxiliary device for welding equipment for mechanical manufacturing is now needed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that in the existing welding process, most of the time, two steel plates are directly placed on the welding surface for welding. Since the positions of the steel plates are not fixed, the positions of the steel plates are prone to shift during the welding process, which in turn causes the butt weld of the two steel plates to be too large or even causes the butt weld of the two steel plates to be uneven, thereby affecting the welding quality of the steel plates and causing inconvenience to the workers in actual operation. An auxiliary device for welding equipment for mechanical manufacturing is proposed to solve the problem that in the existing welding process, most of the time, two steel plates are directly placed on the welding surface for welding.

[0030] Reference Figure 1-Figure 6 A welding equipment auxiliary device for mechanical manufacturing comprises an L-shaped fixed plate 1, an electric push rod 3 and an L-shaped movable plate 4. The outer wall of the fixed plate 1 is provided with a mounting hole 2, the inner wall of the mounting hole 2 is provided with an electric push rod 3, the telescopic end of the electric push rod 3 is fixedly connected to the movable and telescopic movable plate 4 on the left and right sides of the steel plate, the top of the inner wall of the fixed plate 1 and the movable plate 4 are provided with a cross boss 5 for placing the steel plate and making part of the steel plate suspended, the outer walls of the fixed plate 1 and the movable plate 4 are provided with sliding holes 6 on both sides, the sliding holes 6 are provided with side clamping components 7 that can clamp the front and rear sides of the steel plate, the right outer wall of the movable plate 4 is provided with a limit component to prevent movement, the side clamping component 7 is provided with an auxiliary clamping component 8 that can clamp a small steel plate, and the top of the fixed plate 1 is provided with a correction component 9 that can detect whether the two steel plates are aligned.

[0031] It should be noted that the electric push rod 3, the pulley 23 and the laser level 27 are existing technologies. The specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0032] Furthermore, a slide groove 10 is provided on the outer wall of the fixed plate 1 facing the movable plate 4 , and an insert block 11 is provided on the outer wall of the movable plate 4 facing the fixed plate 1 . The outer wall of the insert block 11 is slidably connected to the inner wall of the slide groove 10 .

[0033] The size of the inner wall of the slide groove 10 is matched with the size of the insert block 11 , so that when the slide groove 10 and the insert block 11 are inserted and connected with each other, the cross bosses 5 on the fixed plate 1 and the movable plate 4 are just merged.

[0034] Furthermore, the inner wall of the slide groove 10 is fixedly connected with symmetrically distributed limiting sliding rods 12, and the limiting sliding rods 12 penetrate the outer wall of the movable plate 4 and are slidably connected.

[0035] Among them, through the fixed connection between the telescopic end of the electric push rod 3 and the outer wall of the plug block 11, we can know that under the action of the electric push rod 3, the movable plate 4 can move with the extension and retraction of the electric push rod 3, and then the distance between the steel plate on the fixed plate 1 and the steel plate on the movable plate 4 can be adjusted.

[0036] Furthermore, the side clamping assembly 7 includes a uniformly distributed spring 15, a slide rod 13, and a clamping plate 14, one end of the spring 15 is fixedly connected to the inner wall of the slide hole 6, the slide rod 13 is slidably connected to the slide hole 6, and the clamping plate 14 is fixedly connected to one end of the slide rod 13.

[0037] The width of the lower end of the clamping plate 14 is much greater than the width of the fixed plate 1 or the movable plate 4, so that the clamping plate 14 can smoothly contact the outer wall of the steel plate to clamp it.

[0038] Furthermore, the spring 15 is sleeved on the outer wall of the slide rod 13, and the other end of the spring 15 is fixedly connected to the outer wall of the clamping plate 14. The other end of the slide rod 13 is located in the slide hole 6. The slide holes 6 on the front side and the slide holes 6 on the rear side of the fixed plate 1 and the movable plate 4 are staggered and do not contact each other.

[0039] Among them, the side clamping assembly 7 is moved outward by manually pulling the clamping plate 14, and the clamping plate 14 drives the sliding rod 13 to slide out of the sliding hole 6, and at the same time stretches the spring 15. After the clamping plates 14 on the front and rear sides contact the outer wall of the steel plate, the spring 15 returns to its original position under the action of elasticity, and the steel plate is firmly clamped in the middle.

[0040] Furthermore, the limiting assembly includes a limiting rod 16, an extension column 17, a semicircular sleeve 18, a placement groove 19, and a movable groove 20. The semicircular sleeve 18 is fixedly connected to the outer wall of the movable plate 4, the limiting rod 16 is slidably connected to the semicircular sleeve 18, the extension column 17 is fixedly connected to the top outer wall of the limiting rod 16, the movable groove 20 is arranged on the outer wall of the semicircular sleeve 18, and the placement groove 19 is arranged at the top of the semicircular sleeve 18.

[0041] Among them, the limiting component is to limit the contact and support of the insertion rod 16 with the ground, so that the movable plate 4 cannot move easily. The extension column 17 slides in the movable groove 20. When the extension column 17 moves to the top end, it can be placed on the placement groove 19, so that the limiting insertion rod 16 can be away from the ground and no longer restrict the movement of the movable plate 4.

[0042] Furthermore, the bottom end of the fixed plate 1 is fixedly connected with support rods 21 which are symmetrically distributed, the bottom end of the support rods 21 is fixedly connected with anti-skid pads 22, and the bottom end of the movable plate 4 is fixedly connected with pulleys 23 which are symmetrically distributed.

[0043] Among them, the support foot composed of the support rod 21 and the anti-skid pad 22 can prevent the fixed plate 1 from moving at will, and the pulley 23 makes the movement of the movable plate 4 more convenient and also makes the movement of the auxiliary device as a whole easier.

[0044] Furthermore, the auxiliary clamping assembly 8 includes a uniformly distributed circular block 30, a rack 31, a fixed extension plate 32, a rotating shaft 33, a gear 34, a pushing plate 35, and a receiving groove 36. The circular block 30 is fixedly connected to the outer wall of the clamping plate 14, the rack 31 is slidably connected to the inner wall of the circular block 30, the fixed extension plate 32 is fixedly connected to the outer wall of the clamping plate 14, the rotating shaft 33 is rotatably connected to the fixed extension plate 32, the gear 34 is rotatably connected to the bottom end of the fixed extension plate 32, the pushing plate 35 is fixedly connected to the inward end of the rack 31, and the receiving groove 36 is arranged on the outer wall of the inward end of the circular block 30.

[0045] Among them, the auxiliary clamping component 8 is achieved by manually rotating the rotating shaft 33, the rotating shaft 33 drives the gear 34 to rotate, the gear 34 drives the rack 31 to slide in the groove of the circular block 30, and the rack 31 pushes the pushing plate 35 to clamp the two sides of the steel plate, so that the steel plate with an area smaller than the fixed plate 1 can also be clamped.

[0046] Furthermore, the rack 31 and the gear 34 are meshed with each other, the rotating shaft 33 is fixedly connected to the top of the gear 34 , the push plate 35 and the receiving groove 36 are adapted in shape and size, and the push plate 35 and the receiving groove 36 are slidably connected.

[0047] The position of the rack 31 is higher than the top of the cross boss 5 so that the rack 31 will not be blocked by the cross boss 5 when moving inward.

[0048] Furthermore, the correction component 9 includes a rectangular slide 24, a fixed rod 25, a rotating slider 26, a laser level 27, a socket 28, and a pin 29. The rectangular slide 24 is arranged at the top of the fixed plate 1, the fixed rod 25 is fixedly connected to the inner wall of the rectangular slide 24, the rotating slider 26 is slidably connected to the fixed rod 25, the laser level 27 is rotatably connected to the rotating slider 26, the socket 28 is arranged on the outer wall of the fixed plate 1, and the pin 29 is inserted into the socket 28 to make the rotating slider 26 immovable, and the rotating slider 26 is slidably connected to the rectangular slide 24.

[0049] Among them, the correction component 9 is achieved by manually pushing the rotating slider 26 to slide on the fixed rod 25, and the laser level 27 can emit a linear laser to facilitate the correction of the position of the steel plate. The combination of the two allows the position of the laser level 27 to be adjusted, and steel plates of different sizes can be detected; a hole is opened on the side of the rotating slider 26 facing the socket 28. When the rotating slider 26 needs to be fixed, it is only necessary to connect the pin 29 to the hole through the socket 28.

[0050] Working principle: When using the device, first start the electric push rod 3, the electric push rod 3 pushes the movable plate 4 away from the fixed plate 1, and then place the two steel plates on the cross bosses 5 on the fixed plate 1 and the movable plate 4 respectively, and then manually pull the clamping plate 14 to move outward, the clamping plate 14 drives the slide rod 13 to slide out of the slide hole 6, and at the same time stretches the spring 15, after the clamping plates 14 on the front and rear sides contact the outer wall of the steel plate, the spring 15 returns to its original position under the action of elasticity, and the steel plate is firmly clamped in the middle, and the electric push rod 3 is started again to bring the movable plate 4 closer to the fixed plate 1 until the two steel plates are in contact, thus completing the clamping and placement of the steel plates.

[0051] If the steel plate is too small for the fixed plate 1 and the movable plate 4 to clamp, the rotating shaft 33 can be rotated manually, and the rotating shaft 33 drives the gear 34 to rotate, and the gear 34 drives the rack 31 to slide in the groove of the circular block 30. The rack 31 pushes the pushing plate 35 to clamp both sides of the steel plate, so that the steel plate smaller than the area of ​​the fixed plate 1 can also be clamped. Then, the rotating slider 26 can be manually pushed to slide on the fixed rod 25, and the laser level 27 can be started to emit a linear laser to correct the position of the steel plate. The combination of the two makes it possible to adjust the position of the laser level 27, so that steel plates of different sizes can be detected.

[0052] Finally, the limiting rod 16 is lifted by the extension column 17, so that the extension column 17 leaves the placement groove 19 and moves downward along the movable groove 20 until the limiting rod 16 contacts the ground, thereby fixing the position of the steel plate. It will not easily shift during the welding process, and it is not easy to affect the welding quality of the steel plate, which is more convenient for the staff to operate.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
