Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools, in particular to an auxiliary tool for welding a T-shaped section steel and a flat steel plate with a ball. Background Technique

[0002] During the ship section manufacturing process, it is often necessary to longitudinally and parallelly weld a plurality of flat steel bars with balls on the upper surface of a steel plate (such as a longitudinal bulkhead plate) as longitudinal stiffeners, and then horizontally and parallelly weld a plurality of T-shaped section steels on the upper surface of the steel plate as transverse stiffeners. The T-shaped section steel is provided with a through hole for the flat steel bar with a ball to extend into; however, when installing the existing T-shaped section steel, it is necessary to first install a reinforcing support between the T-shaped section steel and the steel plate to prevent the T-shaped section steel from deforming during the welding process.

[0003] For example, after retrieval, the utility model patent with the Chinese patent publication number CN217799827U discloses: an auxiliary tool for welding a T-shaped section steel and a flat steel plate with a ball, including two clamps, two vertical rods, a support top plate and a jack; the two vertical rods are arranged at intervals, and through holes are oppositely arranged at the upper parts of the two vertical rods; both ends of the support top plate are respectively installed through the through holes of the two vertical rods; the two clamps are respectively arranged at the lower parts of the two vertical rods, and the clamps are provided with ball section accommodating grooves matching the shape of the ball section of the flat steel bar with a ball; the vertical rod cooperates with the corresponding clamp to limit the ball section of the flat steel bar with a ball embedded in the ball section accommodating groove; the jack is placed between the support top plate and the panel of the T-shaped section steel; the device of the utility model has a simple structure, is convenient to operate, can be reused, can effectively fix the T-shaped section steel, ensure its stability and perpendicularity during welding, and will not leave a mark after use, avoiding subsequent grinding and spraying operations, saving manpower and material resources while shortening the production cycle;

[0004] However, the above existing device will still have the following problems in the actual use process:

[0005] During the process of clamping the steel by the above existing device, only one flat steel plate with a ball can be clamped and fixed. After welding, it is necessary to transfer the clamping device and then perform the clamping operation again. This clamping method reduces the clamping effect of synchronously clamping the flat steel plates with balls, and thus reduces the welding efficiency. Therefore, we propose an auxiliary tool for welding a T-shaped section steel and a flat steel plate with a ball to solve the above-mentioned problems. Content of the Utility Model

[0028] Embodiment

[0029] Please refer to Figures 1-4 , an auxiliary tooling for welding a T-shaped profile and a bulb flat steel plate, comprising a workbench 1, a T-shaped steel 2 and a bulb flat steel 3. The bottom end of the bulb flat steel 3 is attached to the top end of each T-shaped steel 2. The T-shaped steel 2 is closely attached to the top end of the workbench 1 through a plurality of first clamping mechanisms, and the bulb flat steel 3 is closely attached to the top end of the workbench 1 through a second clamping mechanism; The first clamping mechanism includes a first fixing plate 4, which is fixedly installed on the top end of the workbench 1. A first screw rod 6 is rotatably installed horizontally through the first fixing plate 4. A first clamping plate 5 is screwed on the first screw rod 6. A limiting mechanism is arranged between each first clamping plate 5; The first fixing plate 4 and the first clamping plate 5 are closely attached to the bottom area of the T-shaped steel 2; The second clamping mechanism includes a second fixing plate 9, which is fixedly installed on the top end of the workbench 1. A second screw rod 7 is rotatably installed on the second fixing plate 9. Two connecting plates 8 are symmetrically and rotatably installed on the second screw rod 7. A second clamping plate 10 is screwed on the second screw rod 7. The second clamping plate 10 and the second fixing plate 9 are closely attached to the bottom area of the bulb flat steel 3;

[0030] Please refer to Figures 1-4, a transmission mechanism is arranged between the two first screws 6. The transmission mechanism includes transmission wheels 11. The transmission wheels 11 are fixedly installed at one end of the first screws 6. A transmission belt 12 is tensioned and sleeved between the two transmission wheels 11. Through the transmission of the transmission wheels 11 and the transmission belt 12, the two first screws 6 perform synchronous rotation operations. One end of the second screw 7 is fixedly installed with a first gear 13, and a second gear 14 is fixedly installed on the first screw 6. The first gear 13 and the second gear 14 are meshed. Through the meshing of the first gear 13 and the second gear 14, when the first screw 6 rotates, it synchronously drives the second screw 7 to perform a rotation operation. For the auxiliary tooling for welding T-shaped profiles and bulb flat steel plates, by rotating the first screw 6, each first clamping plate 5 is synchronously driven to move towards one end close to the first fixing plate 4, and then the bottom area of each T-shaped steel 2 is vertically clamped by the first fixing plate 4 and the first clamping plate 5. By rotating the second screw 7, the second clamping plate 10 is synchronously driven to move towards one end close to the second fixing plate 9, and then the bottom area of the bulb flat steel 3 is clamped and fixed by the second fixing plate 9 and the second clamping plate 10. Thus, the device synchronously clamps and fixes the bulb flat steel 3 and multiple T-shaped steels 2, improving the clamping efficiency of the device for the T-shaped steels 2 and the bulb flat steel 3, improving the welding operation efficiency of the device, and improving the practicability.

[0031] Please refer to Figure 3 , it should also be noted that the limiting mechanism includes a limiting plate 15. The limiting plate 15 is fixedly installed between the two first fixing plates 4 at the farthest end. The limiting plate 15 is slidably connected to each stabilizing plate 16. By installing the limiting plate 15, the limiting operation of each first clamping plate 5 is performed.

[0032] Please refer to Figure 2 , a stabilizing plate 16 is fixedly installed at the top end of the workbench 1. The stabilizing plate 16 is rotationally connected to the two first screws 6. By installing the stabilizing plate 16, the rotation operation of each first screw 6 is improved.

[0033] Please refer to Figure 4 , one end of one of the first screws 6 is fixedly installed with a reciprocating motor 17. The reciprocating motor 17 is fixedly installed at the top end of the workbench 1. By installing the reciprocating motor 17, power support is provided for the first screw 6.

[0034] In summary, when the auxiliary tooling for welding T-shaped steel and bulb flat steel is in use, the T-shaped steel 2 and the bulb flat steel 3 are respectively moved to the top of the workbench 1 and aligned. Then, the reciprocating motor 17 is started. This motor is a well-known device directly purchased in the market by those skilled in the art. Here, we only use it without making improvements to its structure and function, so we will not elaborate on it in detail here. And the motor is provided with a matching control switch, and the installation position of the control switch is selected according to actual practical needs for the convenience of the operator to operate and control. The reciprocating motor 17 outputs power to drive the first screw rod 6 to rotate synchronously. Since the first screw rod 6 and the first clamping plate 5 are screwed together, when the first screw rod 6 rotates, the first clamping plate 5 moves under the limitation of the limiting plate 15. The T-shaped steel 2 is clamped by the first clamping plate 5 and the first fixing plate 4. Through the transmission of the transmission wheel 11 and the transmission belt 12, the two first screw rods 6 are driven to rotate synchronously. When the first screw rod 6 rotates, the second screw rod 7 is driven to rotate through the transmission of the first gear 13 and the second gear 14. When the second screw rod 7 rotates, the second clamping plate 10 is driven to move, and thus the bottom area of the bulb flat steel 3 is clamped and fixed by the second clamping plate 10 and the second fixing plate 9, and then the clamping and fixing operations of multiple T-shaped steels 2 and bulb flat steels 3 are completed.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
