Description

Technical Field

[0001] The utility model relates to the field of welding tooling, in particular to a material discharge device of a welding fixture. Background Art

[0002] The common straight seam steel pipe welding in factories is to align and level the steel pipe before using a manual handheld welding torch for welding. A convenient steel pipe welding device with a convenient unloading is disclosed in the Chinese utility model patent with the announcement number CN217344283U. The convenient steel pipe welding device with a convenient unloading, by setting a protective mechanism, enables the protective glass to shield the position of the welding steel pipe, thereby avoiding the problem of workers being burned by flying sparks during welding, shielding flying sparks during welding, and improving the safety of workers during product welding. In the above structure, two steel pipes are placed on top of two placement components respectively, and they are clamped and fixed by the clamping blocks on the left and right sides, and then welded. In this structure, there is not enough space on the left and right ends for removing the steel pipes, and the steel pipes form a whole after welding, which increases their gravity and cannot be directly removed from the top of the placement component. For this reason, we designed a unloading device for the welding fixture. Utility Model Content

[0003] In order to solve the technical problem that the pipes are welded to form a whole, which increases their gravity and makes it impossible to directly remove the steel pipes from above the placement assembly, the utility model provides a material removal device for a welding fixture.

[0004] The utility model is implemented by the following technical scheme: a material discharge device of a welding fixture, comprising a base, a mounting plate is suspended on the upper surface of the base, two lifting plates are symmetrically and suspended on the front and rear sides of the upper end of the mounting plate, bearing frames are respectively arranged on the left and right sides of the upper end of the lifting plate, a support roller is rotatably installed between the two bearing frames above the same lifting plate through a bearing, a lower slide plate is arranged on the upper rear side of the base, and a baffle plate is arranged on the end of the lower slide plate away from the support roller;

[0005] A sliding frame is provided on both left and right sides above the mounting plate for sliding movement, and a three-jaw chuck is provided on one side of the sliding frame for rotation toward the inside.

[0006] As a further improvement of the above scheme, four symmetrically arranged lifting cylinders are arranged under the mounting plate, and the push rods of the lifting cylinders pass through the mounting plate and are connected to the lifting plate. The two front lifting cylinders are connected to the front lifting plate, and the two rear lifting cylinders are connected to the rear lifting plate. The front and rear lifting cylinders are respectively controlled by two independent external power supplies, so that the height of the support roller can be adjusted. It is suitable for steel pipes with different outer diameters, and it is convenient to move the rear support roller downward, thereby facilitating the unloading of the steel pipe.

[0007] As a further improvement of the above scheme, the lower slide plate is arranged at an angle, and the front end of the lower slide plate is higher than the rear end, and the front end top of the baffle plate is below the middle of the support roller. After the welding of the steel pipes placed on the two support rollers is completed, the lifting plate on the rear side moves downward under the action of the two lifting cylinders. At this time, the rear end of the steel pipe will be deviated backward without support, and will then roll onto the lower slide plate.

[0008] As a further improvement of the above scheme, the frontmost side of the lower slide plate is located on the rear side of the outer ring surface of the rear support roller, and the chamfered corners on the upper edge of the front end of the lower slide plate are designed to form a contact arc surface. There is a certain distance between the front end of the lower slide plate and the support roller. The two will not contact when the support roller moves downward, and when the steel pipe rolls downward, the set contact arc surface avoids scratches on the outer surface of the steel pipe. The baffle plate is designed to be perpendicular to the lower slide plate, and a protective pad is provided on the inward side of the baffle plate. The protective pad is a rubber pad with a certain elasticity to prevent the steel pipe from sliding down too fast and causing damage.

[0009] As a further improvement of the above scheme, two side frames are symmetrically arranged on the left and right sides of the mounting plate, and an adjusting hydraulic cylinder is installed on the outward surface of the side frame. The push rod of the adjusting hydraulic cylinder passes through the side frame, and the push rod of the adjusting hydraulic cylinder is connected to the inward surface of the sliding frame. The extension and retraction of the push rod of the adjusting hydraulic cylinder can control the position of the sliding frame, and then the steel pipes of different lengths can be fixed according to needs, and after welding is completed, it can also be quickly moved away from the steel pipe, which is convenient for unloading.

[0010] As a further improvement of the above-mentioned solution, guide rails are symmetrically arranged on the front and rear sides of the left and right ends of the upper surface of the mounting plate, and sliders are slidably arranged on the guide rails. The sliding frame is fixed on two opposite sliders, thereby reducing the resistance of the sliding frame during movement and facilitating the left and right movement of the sliding frame. It is suitable for steel pipes of various sizes.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model arranges liftable support rollers above the mounting plate, and the rear support rollers can be moved downward as needed, so that the steel pipes above the two support rollers slide backward onto the sliding plate due to the center of gravity offset, which is convenient for subsequent workers to carry away;

[0013] 2. By arranging movable three-jaw chucks on the left and right sides above the mounting plate, the two steel pipes can be quickly pressed and fixed, and by arranging liftable support rollers, it can be ensured that the center of the steel pipe is always in line with the axis of the three-jaw chuck, which is suitable for steel pipes of various sizes.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example:

[0021] Please combine Figure 1-Figure 3 A material discharging device of a welding fixture device of the present embodiment comprises a base 1, a mounting plate 2 is suspended on the upper surface of the base 1, two lifting plates 62 are symmetrically and suspended on the front and rear sides of the upper end of the mounting plate 2, bearing frames 61 are respectively arranged on the left and right sides of the upper end of the lifting plate 62, a support roller 6 is rotatably installed between the two bearing frames 61 above the same lifting plate 62 through a bearing, a lower slide plate 7 is arranged on the upper rear side of the base 1, and a baffle plate 71 is arranged on the end of the lower slide plate 7 away from the support roller 6;

[0022] A sliding frame 8 is slidably arranged on both left and right sides above the mounting plate 2, and a three-jaw chuck 4 is rotatably arranged on one side of the sliding frame 8.

[0023] Four symmetrically arranged lifting cylinders 3 are arranged under the mounting plate 2. The push rods of the lifting cylinders 3 pass through the mounting plate 2 and are connected to the lifting plate 62. The two front lifting cylinders 3 are connected to the front lifting plate 62, and the two rear lifting cylinders 3 are connected to the rear lifting plate 62. The front and rear lifting cylinders 3 are respectively controlled by two independent external power supplies, so as to adjust the height of the supporting roller 6. It is suitable for steel pipes with different outer diameters and is convenient for moving the rear supporting roller 6 downward, so as to facilitate the unloading of the steel pipe.

[0024] The lower slide plate 7 is set at an angle, and the front end of the lower slide plate 7 is higher than the rear end. The top of the front end of the baffle plate 71 is below the middle of the support roller 6. After the welding of the steel pipes placed on the two support rollers 6 is completed, the lifting plate 62 on the rear side moves downward under the action of the two lifting cylinders 3. At this time, the rear end of the steel pipe will be deviated backward without support, and then will roll onto the lower slide plate 7.

[0025] The frontmost side of the lower slide plate 7 is located on the rear side of the outer ring surface of the rear support roller 6, and the chamfered corners on the upper edge of the front end of the lower slide plate 7 form a contact arc surface 73. There is a certain distance between the front end of the lower slide plate 7 and the support roller 6. The two will not contact when the support roller 6 moves downward, and when the steel pipe rolls downward, the contact arc surface 73 is set to avoid scratches on the outer surface of the steel pipe. The baffle plate 71 is designed to be perpendicular to the lower slide plate 7, and a protective pad 72 is set on the inner side of the baffle plate 71. The protective pad 72 is a rubber pad with a certain elasticity to prevent the steel pipe from sliding down too fast and causing damage.

[0026] Two side frames 21 are symmetrically arranged on the left and right sides of the mounting plate 2. An adjusting hydraulic cylinder 5 is installed on the outward surface of the side frame 21. The push rod of the adjusting hydraulic cylinder 5 passes through the side frame 21, and the push rod of the adjusting hydraulic cylinder 5 is connected to the inward surface of the sliding frame 8. The extension and retraction of the push rod of the adjusting hydraulic cylinder 5 can control the position of the sliding frame 8, so that steel pipes of different lengths can be fixed according to needs, and after welding is completed, it can also be quickly away from the steel pipe, so as to facilitate unloading.

[0027] Guide rails 22 are symmetrically arranged on the left and right ends and the front and rear sides of the upper surface of the mounting plate 2. Slide blocks are slidably arranged on the guide rails 22. The sliding frame 8 is fixed on two opposite slide blocks to reduce the resistance of the sliding frame 8 when it moves, thereby facilitating the left and right movement of the sliding frame 8, and is suitable for steel pipes of various sizes.

[0028] The implementation principle of a material discharge device of a welding fixture in the embodiment of the present application is as follows: first, the height of the two support rollers 6 is adjusted according to the actual size of the steel pipe, so that the center of the steel pipe placed above the support rollers 6 is in line with the axis of the three-jaw chuck 4, and then the two steel pipes to be welded can be placed in the space between the two support rollers 6, and the sliding frame 8 moves inward under the action of the push rod of the adjustment hydraulic cylinder 5 and places the claws of the three-jaw chuck 4 on the inner circle of the steel pipe and fixes it, and then welding can be carried out. After the welding is completed, the three-jaw chuck 4 releases the fixation on the steel pipe, and the sliding frame 8 moves outward so that the three-jaw chuck 4 is separated from the steel pipe, and the lifting plate 62 on the rear side moves downward under the action of the two lifting cylinders 3. At this time, the rear end of the steel pipe will be deviated backward without support, and then will roll onto the lower slide plate 7, and the workers can stand on both sides of the steel pipe and lift it away;

[0029] By arranging a liftable support roller 6 above the mounting plate 2, the rear support roller 6 can be moved downward as needed, so that the steel pipe above the two support rollers 6 slides backward onto the lower slide plate 7 due to the center of gravity offset, which is convenient for subsequent workers to carry away;

[0030] By arranging movable three-jaw chucks 4 on the left and right sides above the mounting plate 2, the two steel pipes can be quickly clamped and fixed, and by arranging liftable support rollers 6, it can be ensured that the center of the steel pipe is always in line with the axis of the three-jaw chuck 4, which is suitable for steel pipes of various sizes.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
