[0002] Diaphragm accumulators are important hydraulic components widely used in various hydraulic systems. They are mainly used to store and release hydraulic energy, and play a role in stabilizing system pressure, absorbing pressure pulsations, and compensating for leakage. During the production process, the hemispherical shells need to be connected into a whole by welding.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222037324U, which discloses a welding device for a diaphragm accumulator, including a welding table and a fixing frame; the fixing frame is provided on one side of the top of the welding table, a moving component is provided on the top of the fixing frame, a cylinder is provided at the bottom of the moving component, and a welding gun is provided on one side of the cylinder; a clamping structure is provided on the top of the welding table, and a heat dissipation structure is provided at the front end of the clamping structure.

[0004] The aforementioned device uses a fixed plate and a chuck to fix the accumulator. During installation, the components need to be supported, making the operation inconvenient. For mass production, it requires a lot of physical labor, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a rotary welding platform for diaphragm accumulators to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diaphragm accumulator rotary welding platform, comprising a mounting frame, wherein two symmetrically arranged support rings are fixedly connected to the top of the mounting frame, and a receiving component is installed inside each of the two support rings. The receiving component includes a rotating ring rotatably connected to the inner circumference of the support ring, and a mounting frame is fixedly connected inside the rotating ring. A vertically arranged bidirectional lead screw is rotatably connected inside the mounting frame, and a movable seat is threaded onto the threaded ends of the bidirectional lead screw. A receiving plate is fixedly connected to one side of each of the two movable seats, and the two receiving plates are symmetrically arranged. Two vertically arranged guide rods are fixedly connected inside the mounting frame, and the two movable seats are slidably sleeved on the outside of the two guide rods. A toothed ring is coaxially fixed to the outer circumference of the rotating ring.

[0007] The accumulator housing is directly placed into the double-support plate structure, which automatically completes precise positioning without the need for personnel support. The operation process is simple and efficient. Adjust the position of the two support plates of the support component according to the size of the accumulator housing, and start rotating the bidirectional screw by turning the knob. The rotating bidirectional screw drives the two moving seats to move closer to each other along the guide rod. The support plates fixed outside the moving seats will also be moved synchronously. The operator only needs to push the housing directly between the two support plates without support. The housing will also be in the center of the rotating ring, which helps to improve welding accuracy. Then, drive the two support plates to clamp again to complete the final fixation.

[0008] As a further preferred embodiment of this technical solution, a second support frame is fixedly connected to the top outer wall of the mounting frame. A horizontally arranged transmission rod is rotatably connected inside the second support frame. Two gears are coaxially fixed to the outside of the transmission rod. A second motor is fixedly installed on the outer wall of one end of the second support frame. The output end of the second motor is coaxially fixed to one end of the transmission rod. The two gears mesh with two gear rings respectively.

[0009] As a further preferred embodiment of this technical solution, a support frame is rotatably sleeved on the outside of the mounting frame, and a motor is fixedly installed on one side of the outer wall of the support frame. The output end of the motor is coaxially fixed with one end of the rotating shaft of the support frame.

[0010] As a further preferred embodiment of this technical solution, the receiving plate, the movable seat, the mounting frame, the rotating ring, and the support ring are all made of metal materials.

[0011] As a further preferred embodiment of this technical solution, the thread helix angle of the threads at both ends of the bidirectional lead screw is less than the equivalent friction angle.

[0012] As a further preferred embodiment of this technical solution, the first motor is a stepper motor.

[0013] As a further preferred embodiment of this technical solution, the end of the receiving plate near the middle of the mounting frame is arc-shaped.

[0014] This utility model provides a rotary welding platform for diaphragm accumulators, which has the following advantages:

[0015] This invention, by setting up a receiving component, allows the accumulator housing to be directly placed into a double receiving plate structure, automatically achieving precise positioning without the need for manual assistance. The operation is simple and efficient. The positions of the two receiving plates in the receiving component are adjusted according to the size of the accumulator housing. A knob drives the bidirectional lead screw to rotate, which in turn drives the two moving seats to move closer to each other along the guide rod. The receiving plates fixed outside the moving seats are also moved synchronously. The operator simply pushes the housing directly between the two receiving plates without any support, and the housing is positioned in the center of the rotating ring, which helps improve welding accuracy. Finally, the two receiving plates are clamped together to complete the final fixation. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the diaphragm accumulator rotary welding platform includes a mounting frame 2. Two symmetrically arranged support rings 5 ​​are fixedly connected to the top of the mounting frame 2. A receiving component 4 is installed inside each of the two support rings 5. The receiving component 4 includes a rotating ring 401 rotatably connected to the inner circumference of the support ring 5. A mounting frame 402 is fixedly connected inside the rotating ring 401. A vertically arranged bidirectional lead screw 403 is rotatably connected inside the mounting frame 402. A movable seat 405 is threaded at both ends of the bidirectional lead screw 403. A receiving plate 406 is fixedly connected to one side of each of the two movable seats 405, and the two receiving plates 406 are symmetrically arranged. Two vertically arranged guide rods 404 are fixedly connected inside the mounting frame 402. The two movable seats 405 are slidably sleeved on the outside of the two guide rods 404. A toothed ring 407 is coaxially fixed to the outer circumference of the rotating ring 401.

[0023] A support frame 408 is fixedly connected to the top outer wall of the mounting bracket 2. A horizontally arranged transmission rod 409 is rotatably connected inside the support frame 408. Two gears 411 are coaxially fixed to the outside of the transmission rod 409. A motor 410 is fixedly installed on the outer wall of one end of the support frame 408. The output end of the motor 410 is coaxially fixed to one end of the transmission rod 409. The two gears 411 mesh with two gear rings 407 respectively.

[0024] Adjust the positions of the two receiving plates 406 of the receiving assembly 4 according to the size of the accumulator housing. Drive the bidirectional lead screw 403 to rotate via a knob. The rotating lead screw 403 drives the two moving seats 405 to move closer together along the guide rod 404. The receiving plates 406 fixed to the outside of the moving seats 405 will also move synchronously. The operator simply pushes the housing directly between the two receiving plates 406 without any support. The housing will also be positioned in the center of the rotating ring 401, which helps improve welding accuracy. The final fixation is completed by clamping the two receiving plates 406 together again. During the welding process, the motor 410 outside the support frame 408 is started. The motor 410 drives the transmission rod 409 to rotate, and the gear 411 outside the transmission rod 409 is driven to rotate synchronously. The gear 411 drives the two gear rings 407 to rotate through meshing. The gear rings 407 drive the two rotating rings 401 to rotate. The two housings are fixed on the rotating rings 401 respectively. Therefore, the two housings will be driven to rotate, so that the entire connection can be welded.

[0025] like Figure 1As shown, a support frame 1 is rotatably mounted on the outside of the mounting frame 2. A motor 3 is fixedly mounted on one side of the outer wall of the support frame 1. The output end of the motor 3 is coaxially fixed with one end of the rotating shaft of the support frame 1. If welding is required on the end cover of the accumulator, the motor 3 outside the support frame 1 is started. The motor 3 drives the mounting frame 2 to rotate 90 degrees, and the end cover of the accumulator will be directly aligned with the welding torch of the external welding device, without the need for secondary adjustment.

[0026] like Figure 2 As shown, the receiving plate 406, the movable seat 405, the mounting frame 402, the rotating ring 401 and the support ring 5 are all made of metal. The grounding clamp of the external welding device can be clamped on the outside of the support ring 5 so as to form a passage with the welding torch.

[0027] like Figure 4 As shown, the thread helix angle of the threads at both ends of the bidirectional lead screw 403 is less than the equivalent friction angle, giving it self-locking properties and ensuring that the position of the movable seat 405 connected to it will not change with use.

[0028] like Figure 1 As shown, motor 3 is a stepper motor, which helps to improve the accuracy of the flipping angle of the mounting bracket 2.

[0029] like Figure 1 and Figure 2 As shown, the end of the receiving plate 406 near the middle of the mounting bracket 2 is arc-shaped, which makes the insertion process of the accumulator housing convenient enough.

[0030] This utility model provides a rotary welding platform for diaphragm accumulators, the specific working principle of which is as follows:

[0031] When the device is working, adjust the positions of the two receiving plates 406 of the receiving assembly 4 according to the size of the accumulator housing. Drive the bidirectional lead screw 403 to rotate via a knob. The rotating lead screw 403 drives the two moving seats 405 to move closer together along the guide rod 404. The receiving plates 406 fixed outside the moving seats 405 will also move synchronously. The operator simply pushes the housing directly between the two receiving plates 406 without any support, and the housing will be positioned in the center of the rotating ring 401, which helps improve welding accuracy. Then, drive the two receiving plates 406 to clamp them again to complete the final fixation. During welding, start the support frame two. The external motor 410 drives the transmission rod 409 to rotate. The gear 411 outside the transmission rod 409 is driven to rotate synchronously. The gear 411 meshes with the two gear rings 407 to rotate. The gear rings 407 drive the two rotating rings 401 to rotate. The two housings are fixed on the rotating rings 401 respectively. Therefore, the two housings will be driven to rotate, so that the entire connection can be welded. If welding is required at the end cover of the accumulator, the external motor 3 of the support frame 1 is started. The motor 3 drives the mounting frame 2 to rotate 90 degrees. The end cover of the accumulator will be directly aligned with the welding gun position of the external welding device, without the need for secondary adjustment.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
