Description

Technical Field

[0001] The 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] Diesel generator set is a common power generation equipment, which is composed of a diesel engine and a generator. Diesel generator set has the advantages of high efficiency, reliability, flexibility and economy, so it is regarded as a reliable backup power source in many critical occasions. The core components of diesel generator set are diesel engine and generator. Diesel engine is responsible for converting the energy of fuel (diesel) into mechanical energy, while generator converts mechanical energy into electrical energy.

[0003] In the production process of diesel generator sets, the welding of the shell is an important link. Traditional welding devices often use a fixed clamping method, which is difficult to adapt to shells of different shapes and sizes, resulting in low welding efficiency and difficulty in ensuring welding quality. In addition, when clamping the shell, traditional welding devices are often unable to adjust the angle of the shell according to welding requirements, which brings inconvenience to the welding operation. Therefore, it is particularly important to develop a diesel generator shell welding device that can adapt to shells of different shapes and sizes and can self-adjust the angle. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that welding devices in the prior art often adopt a fixed clamping method, which is difficult to adapt to shells of different shapes and sizes, resulting in low welding efficiency and difficulty in ensuring welding quality. In addition, when clamping the shell, the traditional welding device often cannot adjust the angle of the shell according to the welding requirements, which brings inconvenience to the welding operation. A diesel generator shell welding device with an angle self-adjusting function is proposed.

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

[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 a rotating rectangular plate, a rectangular cavity is opened inside the rotating rectangular plate, and a clamping assembly for clamping the shell is penetrated inside the rotating rectangular plate;

[0008] A fixing component for fixing the position of the housing is arranged inside the rectangular cavity;

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

[0010] In a 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 a possible design, the clamping assembly includes a plurality of clamping rods that slide through the interior of a rotating rectangular plate, one end of the clamping rod is fixedly connected to a first limit plate, one side of the first limit plate and one side of the rotating rectangular plate are fixedly connected with a same tension spring, the tension spring is sleeved on the outside of the clamping rod, and a plurality of slots are provided on the top of the clamping rod.

[0012] In a possible design, the clamping assembly also includes four limiting round rods that slide through the inside of the rotating rectangular plate and are symmetrical in pairs. 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 a possible design, the fixed component 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, the bottom inner wall of the rectangular cavity is slidably connected with two symmetrically arranged sliding blocks, one side of the sliding block is fixedly connected to the inner wall of one side of the rectangular cavity with the same second spring, one side of the sliding block is fixedly connected with a limiting protrusion, the limiting protrusion is used to fix the fixed rectangular block, 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 pushing rods, one end of the pushing rod slides through the rotating rectangular plate and is used in conjunction 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. The bidirectional screw thread passes through the two U-shaped plates, and one end of the bidirectional screw is fixedly connected to a handwheel. 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 the present application, when in use, the shell of the generator 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 approach each other, the two U-shaped plates drive the two sliding rectangular plates to approach each other, and start to clamp the shell of the generator;

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

[0020] When the sliding rectangular plate moves, the two triangular blocks are driven to move horizontally. The inclined surfaces of the triangular blocks are in conflict with the strip plates, and the strip plates can be pushed 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, so that the shell is suspended. When the support plate moves, it drives the slider to move and squeeze the third spring, so as to facilitate the reset of the support plate.

[0021] When the sliding rectangular plate moves to the farthest point, the rotating rectangular plate moves to 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 the top of the limiting convex block to the bottom of the limiting convex block. Since the bottom of the limiting convex block is a plane, the fixed rectangular block cannot move upward, and the sliding cross plate drives multiple plug rods to move downward, and the plug 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 rotate normally around the rotating axis, the workers can adjust the angle of the rotating rectangular plate at will according to their needs, thereby facilitating the welding process. When the clamping state of the device needs to be released, the two second limit plates under the labor can be used. The second limit plate drives the limit round rod and the clamping plate to move laterally, and the clamping plate drives the push rod to move laterally. The push rod pushes the limit protrusion to move laterally, so that the limit protrusion squeezes the second spring and retracts. Since the push rod and the fixed rectangular block are staggered, when the limit protrusion is disengaged from the fixed rectangular block, the braking state of the sliding protrusion plate and the sliding cross plate contacts, and the hand wheel is rotated in the opposite direction. At this time, the arc surface of the sliding protrusion plate can contact the top of the processing table, so that the sliding protrusion plate is retracted, and then the shell can be loosened, which is convenient for the next welding process.

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

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

[0025] The fixing assembly, through the cooperation of the sliding cross plate, the sliding convex plate, the plug rod and other components, can further fix the shell after the clamping rod initially clamps the shell, ensuring that the shell will not be displaced during the welding process, thereby ensuring the welding quality.

[0026] The adjustment assembly can easily adjust the position of the two sliding rectangular plates through the cooperation of the bidirectional screw rod, U-shaped plate and other components, thereby realizing the clamping and loosening operation of the shell. In addition, when the clamping state of the device needs to be released, it only needs to push the second limit plate below, which is simple and quick to operate.

[0027] The overall structure of the device is compact and the components are closely matched, which not only improves the stability and reliability of the device but also facilitates maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
