Description

Technical Field

[0001] The present invention relates to the technical field of diesel generator sets, and in particular to a diesel generator set shell welding device with an angle self-adjusting function. Background Art

[0002] A diesel generator set is a common type of power generation equipment, consisting of a diesel engine and a generator. Due to their high efficiency, reliability, flexibility, and cost-effectiveness, they are considered a reliable backup power source in many critical situations. The core components of a diesel generator set are the diesel engine and generator. The diesel engine converts the energy of the fuel (diesel) into mechanical energy, while the generator converts mechanical energy into electrical energy.

[0003] Casing welding is a crucial step in the production of diesel generator sets. Traditional welding devices often employ a fixed clamping mechanism, making it difficult to adapt to casings of varying shapes and sizes. This results in low welding efficiency and poor weld quality. Furthermore, traditional welding devices often fail to adjust the angle of the casing when clamping it, creating inconvenience during welding. Therefore, developing a diesel generator casing welding device that can adapt to various shapes and sizes and can self-adjust its angle is crucial. Summary of the Invention

[0004] The present invention aims to address the problem that existing welding devices often use a fixed clamping method, making it difficult to adapt to shells of varying shapes and sizes, resulting in low welding efficiency and poor welding quality. Furthermore, conventional welding devices often cannot adjust the shell angle when clamping the shell, which brings inconvenience to the welding operation. The proposed device is a diesel generator shell welding device with a self-adjusting angle function.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A diesel generator housing welding device with an angle self-adjustment function includes a processing table and a welding gun. The welding gun is placed on one side above the processing table. A rectangular groove is formed on the top of the processing table. The inner walls on both sides of the rectangular groove are each provided with a connecting notch. A support assembly for supporting the housing is provided inside the notch.

[0007] The top of the processing table is slidably connected to two symmetrically arranged sliding rectangular plates, one side of the sliding rectangular plate is rotatably connected to a rotating shaft, one end of the rotating shaft is fixedly connected to the rotating rectangular plate, a rectangular cavity is opened inside the rotating rectangular plate, and a clamping assembly for clamping the shell is provided through the inside of the rotating rectangular plate;

[0008] A fixing assembly for fixing the position of the housing is provided inside the rectangular cavity;

[0009] An adjustment component for adjusting the positions of two sliding rectangular plates is provided inside the processing table.

[0010] In one possible design, the support assembly includes two sliding grooves respectively opened on the inner walls on both sides of the notch, a slider is slidably connected inside the sliding groove, a third spring is fixedly connected between one side of the slider and the inner wall of one side of the sliding groove, and a support plate is fixedly connected between the two sliders on the same side.

[0011] In one possible design, the clamping assembly includes a plurality of clamping rods that slide through the interior of the rotating rectangular plate, one end of the clamping rod is fixedly connected to a first limit plate, a same tension spring is fixedly connected between one side of the first limit plate and one side of the rotating rectangular plate, the tension spring is sleeved on the outside of the clamping rod, and a plurality of slots are opened on the top of the clamping rod.

[0012] In a possible design, the clamping assembly also includes four symmetrical limiting round rods that slide through the inside of the rotating rectangular plate, one end of two limiting round rods located at the same height is fixedly connected to the same clamping plate, one end of the limiting round rod is fixedly connected to a second limiting plate, and two symmetrically arranged first springs are fixedly connected between one side of the clamping plate and one side of the rotating rectangular plate.

[0013] In one possible design, the fixing assembly includes a sliding horizontal plate slidably connected to the inner wall of the rectangular cavity, a sliding convex plate is fixedly connected to the middle position of the bottom of the sliding horizontal plate, a rectangular hole is opened in the middle position of the bottom of the rotating rectangular plate, the bottom of the sliding convex plate passes through the rectangular hole, two symmetrically arranged compression springs are fixedly connected between the top of the sliding horizontal plate and the top of the rectangular cavity, and a plurality of plug rods are fixedly connected to the bottom of the sliding horizontal plate, and the plug rods are engaged with the slots.

[0014] In a possible design, the fixing assembly also includes two fixed rectangular blocks respectively fixedly connected to the two sides of the sliding protrusion, and the bottom inner wall of the rectangular cavity is slidably connected with two symmetrically arranged sliding blocks. The same second spring is fixedly connected between one side of the sliding block and one side inner wall of the rectangular cavity, and one side of the sliding block is fixedly connected to a limiting protrusion. The limiting protrusion is used to fix the fixed rectangular block, and the size of the limiting protrusion is larger than the size of the fixed rectangular block. One side of the clamping plate located below is fixedly connected with two symmetrically arranged push rods, and one end of the push rod slides through the rotating rectangular plate and cooperates with the limiting protrusion.

[0015] In one possible design, the adjustment assembly includes a bidirectional screw that rotates and passes through the inside of the processing table, and U-shaped holes are opened on the inner walls on both sides of the rectangular groove. A U-shaped plate is slidably connected to the inside of the U-shaped hole, and the bidirectional screw thread passes through the two U-shaped plates. One end of the bidirectional screw is fixedly connected to a handwheel, and the top of the U-shaped plate is fixedly connected to the bottom of the sliding rectangular plate.

[0016] In a possible design, a strip plate is fixedly connected to one side of the top of the support plate, and triangular blocks are fixedly connected to both sides of the sliding rectangular plate, and the triangular blocks are used in conjunction with the strip plate.

[0017] In a possible design, two symmetrically arranged clearance holes are opened inside the sliding rectangular plate, and the clearance holes are used in conjunction with a plurality of first limiting plates.

[0018] In this application, when in use, the generator housing is placed on two support plates, ready for welding operation, the hand wheel is turned, the hand wheel drives the bidirectional screw to rotate, the bidirectional screw drives the two U-shaped plates to move closer to each other, and the two U-shaped plates drive the two sliding rectangular plates to move closer to each other, and start clamping the generator housing;

[0019] At this time, multiple clamping rods gradually come into contact with the shell and can be gradually moved back to different lengths according to the different shapes of the generator shell to adapt to the outer shape of the shell. At the same time, the clamping rod drives the first limit plate to move laterally and stretches the tension spring. At this time, the shell can be initially clamped. When one side of the clamping plate contacts the shell, the hand wheel is stopped and the shell is clamped again by the clamping plate.

[0020] When the sliding rectangular plate moves, it drives the two triangular blocks to move horizontally. The inclined surfaces of the triangular blocks come into conflict with the strip plates, which can push the strip plates away from both sides. The two strip plates drive the two support plates to move away from each other. When the clamping rod clamps the shell, the support plate is separated from the shell, making the shell suspended in the air. When the support plate moves, it drives the slider to move and squeeze the third spring, which facilitates the reset of the support plate.

[0021] When the sliding rectangular plate moves to the farthest point, the rectangular plate is rotated to move into the inside of the rectangular groove. At this time, the sliding cross plate and the sliding convex plate move vertically downward under the elastic force of the compression spring, and the bottom of the sliding convex plate passes through the rectangular hole. At the same time, the sliding convex plate drives the fixed rectangular block to move vertically downward, and the fixed rectangular block moves from above the limit protrusion to below the limit protrusion. Since the bottom of the limit protrusion is a flat surface, the fixed rectangular block cannot move upward, and the sliding cross plate drives multiple insertion rods to move downward. The insertion rods are inserted into the corresponding slots to brake the clamping rods to ensure the stability of the shell clamping;

[0022] At this time, the shell can be welded, and since the rotating rectangular plate can normally rotate around the rotating shaft, workers can adjust the angle of the rotating rectangular plate at will according to needs, thereby facilitating the welding process. When it is necessary to release the clamping state of the device, the two second limiting plates below can be pushed to drive the limiting round rod and the clamping plate to move transversely, the clamping plate drives the push rod to move transversely, the push rod pushes the limiting protrusion to move transversely, so that the limiting protrusion extrudes the second spring and is retracted. Since the push rod and the fixed rectangular block are misaligned, when the limiting protrusion is disengaged from the fixed rectangular block, the sliding protrusion and the sliding transverse plate are in contact in the braking state, and the hand wheel is reversely rotated. At this time, the arc surface of the sliding protrusion can be in contact with the top of the machining table, so that the sliding protrusion is retracted, thereby releasing the shell, and facilitating the next welding process.

[0023] Beneficial effects: the device can adaptively clamp according to the different shapes of the generator shell through the clamping rod and the clamping plate in the clamping assembly. The clamping rod can gradually abut against the shell under the action of the tension spring and gradually move back different lengths according to the shape of the shell, thereby ensuring that the shell is stably clamped.

[0024] The rotating rectangular plate can normally rotate around the rotating shaft, and workers can adjust the angle of the rotating rectangular plate at will according to the welding needs, thereby facilitating the welding process and improving the flexibility and efficiency of welding.

[0025] The fixed assembly can further fix the shell after the clamping rod preliminarily clamps the shell through the cooperation of the sliding transverse plate, the sliding protrusion, the plug rod and the like, so as to ensure that the shell does not displace during the welding process and ensure the welding quality.

[0026] The adjusting assembly can conveniently adjust the positions of the two sliding rectangular plates through the cooperation of the bidirectional screw rod and the U-shaped plate, so as to realize the clamping and releasing operations of the shell. In addition, when it is necessary to release the clamping state of the device, the second limiting plate below only needs to be pushed, and the operation is simple and quick.

[0027] The device has a compact overall structure and a close cooperation between components, which not only improves the stability and reliability of the device, but also facilitates maintenance and maintenance. BRIEF DESCRIPTION OF DRAWINGS
