Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to a welding fixture for fixing a water booster. Background Technology

[0002] In rail transportation, the water booster is a key component of the train's toilet system. It primarily functions to pressurize low-pressure water into a high-pressure flushing flow, thereby efficiently cleaning the toilets. The water booster consists of an upper cover, a lower cover, a sealing ring, and a sealing plate. The sealing ring is positioned between the upper and lower covers, and the sealing plate is welded between them to ensure the water booster's sealing performance.

[0003] In related technologies, the sealing plate in the water booster is welded between the upper and lower covers. This is done by manually attaching the sealing plate between the upper and lower covers, and then welding it in place.

[0004] However, the relevant technologies have low operating efficiency and are prone to situations where the sealing plate cannot fit tightly with the sealing ring, resulting in poor sealing performance. Utility Model Content

[0005] This application provides a welding fixture for fixing a water booster, which solves the problems of low work efficiency and poor sealing performance caused by the sealing plate failing to fit tightly with the sealing ring.

[0006] This application provides a welding fixture for fixing a water booster, comprising:

[0007] Support frame with tool storage section;

[0008] The clamping mechanism includes a first clamping component and a second clamping component. The first clamping component is mounted on a support frame and moves up and down relative to the support frame. The second clamping component is mounted on a tool placement part and has a movable clamping part that moves relative to the support frame to clamp or release the water booster.

[0009] The first clamping assembly is configured to descend and abut against the second clamping assembly to clamp the water booster when the clamping part clamps the water booster; and to rise and separate from the second clamping assembly to release the clamping of the water booster when the clamping part releases the water booster.

[0010] In some embodiments, the first clamping assembly includes a drive member and a pressure plate. The drive member is disposed on a support frame and connected to the pressure plate to drive the pressure plate to move up and down relative to the support frame.

[0011] In some embodiments, a support platform is provided on the support frame, a drive member is provided on the support platform, a clearance hole is provided on the support platform, the drive part of the drive member is connected to the pressure plate through the clearance hole, and the pressure plate is located below the support platform.

[0012] In some embodiments, the pressure plate is provided with a clearance notch to avoid the clamping portion.

[0013] In some embodiments, the clamping part includes a plurality of jaws, and the jaws are provided with a buffer assembly for abutting against the sealing plate of the water booster.

[0014] In some embodiments, the buffer assembly includes a clamping screw, a buffer pad, and a locking screw, wherein the clamping screw passes through the jaw and the buffer pad in sequence, and the end of the clamping screw is provided with a threaded hole;

[0015] The locking screw engages with the threaded hole and abuts against the buffer pad to secure it. The buffer pad is used to abut against the sealing plate of the water booster.

[0016] In some embodiments, the second clamping assembly includes a chuck and a rotating member. The chuck is disposed on the tool placement portion, the clamping portion is movably disposed on the chuck, and the rotating member is rotatably disposed on the chuck. The rotating member drives the clamping portion to move radially along the chuck so that the clamping portion is used to clamp or release the water booster.

[0017] In some embodiments, a first bevel gear and a second bevel gear are provided in the chuck, a rotating member extends into the first bevel gear and drives the first bevel gear to rotate, the first bevel gear meshes with the second bevel gear, the second bevel gear is provided with a first planar thread, and the clamping part is provided with a second planar thread that mates with the first planar thread;

[0018] The second bevel gear is configured such that when the rotating member drives the first bevel gear to rotate, the second bevel gear rotates and drives the clamping part to move radially along the chuck, so that the clamping part is used to clamp or release the water booster.

[0019] In some embodiments, the rotating component is a rotary wrench, and a mounting hole is provided in the first bevel gear, with the rotary wrench engaging with the mounting hole.

[0020] In some embodiments, the tool placement section is a support plate.

[0021] This application provides a welding fixture for fixing a water booster, which includes a support frame and a clamping mechanism. The operation of the first and second clamping components relies on the rigid support of the support frame and the tool placement part to avoid component deformation caused by local stress concentration. Through the dual constraint structure of lateral clamping and vertical clamping, a three-dimensional fixing effect is formed, effectively resisting the movement of the water booster in operation, handling, or vibration environments. The clamping part of the second clamping component can move horizontally, thereby enabling clamping and releasing the water booster, reducing manual operation steps, minimizing human error, and improving work efficiency. The movable clamping part and the liftable first pressing assembly can adapt to water boosters of different sizes and shapes within a certain range. The first pressing assembly descends vertically, so that the upper and lower covers of the water booster are respectively sealed with the sealing ring. In order to ensure that the sealing plate of the water booster fits with the sealing ring, the clamping part moves horizontally to clamp the sealing plate of the water booster, so that there is a contact force between the sealing plate and the sealing ring in the horizontal direction, ensuring that the sealing plate and the sealing ring abut against each other, thereby avoiding the situation where the sealing ring and the sealing plate cannot fit tightly, and improving the sealing effect of the water booster.

[0032] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] The existing water booster includes an upper cover, a lower cover, a sealing ring, and a sealing plate. The sealing ring is located between the upper cover and the lower cover. When a downward force is applied to the upper cover, the upper cover and the sealing ring, as well as the lower cover and the sealing ring, form a sealing fit. The sealing plate is welded between the upper cover and the lower cover to ensure the sealing effect of the water booster.

[0035] However, the existing technology involves manually applying downward force to the top cover, using the sealing ring to achieve a sealing effect, and then manually attaching the sealing plate between the top and bottom covers, followed by welding the sealing plate to fix it. This process is inefficient, and there may be instances where the top cover and the sealing ring or the bottom cover and the sealing ring cannot fit tightly together, resulting in poor sealing performance of the water booster.

[0036] In view of this, this application provides a welding fixture for fixing a water booster to solve the problems of low operation efficiency and poor sealing performance caused by the sealing plate failing to fit tightly with the sealing ring in the prior art.

[0037] The welding fixture for fixing a water booster provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0038] like Figures 1 to 3 As shown, the welding fixture for fixing the water booster in this embodiment includes a support frame 100 and a clamping mechanism 200.

[0039] The support frame 100 includes a tool placement section 110.

[0040] The clamping mechanism 200 includes a first clamping component 210 and a second clamping component 220. The first clamping component 210 is disposed on the support frame 100 and moves up and down relative to the support frame 100. The second clamping component 220 is disposed on the tool placement part 110. The second clamping component 220 has a movable clamping part 221, which moves relative to the support frame 100 to clamp or release the water booster 400.

[0041] The first clamping assembly 210 is configured such that when the clamping part 221 clamps the water booster 400, it descends and abuts against the second clamping assembly 220 to clamp the water booster 400; when the clamping part 221 releases the water booster 400, it rises and separates from the second clamping assembly 220 to release the clamping of the water booster 400.

[0042] In the above structure, the first clamping component 210 can be raised and lowered on the support frame 100, the water booster 400 can be placed on the second clamping component 220, and the second clamping component 220 is movably provided with a clamping part 221, so that the clamping part 221 can position and clamp the water booster 400 in the horizontal direction, preventing the water booster 400 from moving horizontally on the second clamping component 220. The first clamping component 210 can be lowered and abut against the second clamping component 220, thereby applying a vertical force to the water booster 400 to ensure that the water booster 400 is fixed and to prevent the water booster 400 from shaking.

[0043] In the initial state, the first clamping assembly 210 is in the raised position, separated from the second clamping assembly 220, allowing the water booster 400 to be placed on the tool placement section 110. In the clamping state, after the water booster 400 is placed on the second clamping assembly 220, the clamping part 221 of the second clamping assembly 220 moves towards the water booster 400, clamping it laterally (or horizontally) to achieve initial positioning and restrict its horizontal displacement. During the clamping phase, after the clamping part 221 completes its clamping action, the first clamping assembly 210 descends along the support frame 100 until it abuts against the second clamping assembly 220. At this time, the first clamping assembly 210 applies pressure vertically, working in conjunction with the clamping force of the second clamping assembly 220 to firmly fix the water booster 400 on the tool placement section 110, further restricting its vertical displacement. During the release phase, and when it is necessary to remove the water booster 400, the clamping part 221 of the second clamping assembly 220 first moves away from the water booster 400 to release the lateral clamping. Simultaneously, the first clamping assembly 210 rises along the support frame 100 and separates from the second clamping assembly 220, releasing the vertical pressure, and the water booster 400 can be removed from the tool placement part 110.

[0044] The welding fixture for fixing a water booster provided in this embodiment relies on the rigid support of the support frame 100 and the tool placement part 110 to prevent component deformation caused by local stress concentration. Through a dual constraint structure of lateral clamping and vertical clamping, a three-dimensional fixing effect is achieved, effectively resisting the movement of the water booster 400 in operation, handling, or vibration environments. The clamping part 221 of the second clamping component 220 can move horizontally, thereby enabling clamping and releasing the water booster 400, reducing manual operation steps, minimizing human error, and improving work efficiency. The movable clamping part 221 and the liftable first pressing assembly 210 can adapt to water boosters 400 of different sizes and shapes within a certain range. The first pressing assembly 210 descends vertically, so that the upper and lower covers of the water booster 400 are respectively sealed with the sealing ring. In order to ensure that the sealing plate of the water booster 400 fits with the sealing ring, the clamping part 221 moves horizontally to clamp the sealing plate of the water booster 400, so that the sealing plate and the sealing ring have a contact force in the horizontal direction, ensuring that the sealing plate and the sealing ring abut against each other, thereby avoiding the situation where the sealing ring and the sealing plate cannot fit tightly, and improving the sealing effect of the water booster 400.

[0045] like Figures 1 to 3As shown, in some embodiments, the first pressing assembly 210 includes a driving member 211 and a pressure plate 212. The driving member 211 is disposed on the support frame 100 and is connected to the pressure plate 212 to drive the pressure plate 212 to rise and fall relative to the support frame 100.

[0046] In this application, the drive member 211 is fixed to the support frame 100 and provides driving force as a power source. The pressure plate 212, as an actuator, is directly connected to the drive member 211 and can abut against the second clamping assembly 220 and apply pressure. After the clamping part 221 of the second clamping assembly 220 completes the lateral clamping of the water booster 400, the drive member 211 receives a trigger signal and transmits power to the pressure plate 212 through actions such as extension, retraction, and movement, driving the pressure plate 212 to move downward along the vertical direction of the support frame 100. After the pressure plate 212 descends to contact the second clamping assembly 220, it maintains pressure under the continuous force of the drive member 211, forming a combined effect with the clamping force of the second clamping assembly 220. When the clamping part 221 releases the clamp, the drive member 211 moves in the opposite direction, driving the pressure plate 212 to rise and reset, separating from the second clamping assembly 220 and releasing the vertical pressure on the water booster 400.

[0047] Specifically, the drive unit 211 can drive the pressure plate 212 to rise and fall by means of a telescopic cylinder or an electric push rod, thereby improving work efficiency. The pressure plate 212 is rigidly connected to the support frame 100 through the drive unit 211. Together with the support frame 100, it can effectively eliminate swaying or offset during the lifting process, ensure accurate docking position with the second pressing component 220, and avoid local stress concentration caused by misalignment.

[0048] It should be noted that the drive component 211 is easy to link with the control system and can automatically trigger the lifting action according to the clamping state of the second clamping component 220 without manual intervention, thereby further improving the automation level and operation efficiency of the device.

[0049] like Figures 1 to 3 As shown, in some embodiments, a support platform 120 is provided on the support frame 100, a drive member 211 is provided on the support platform 120, a clearance hole is provided on the support platform 120, and the drive part of the drive member 211 is connected to the pressure plate 212 through the clearance hole. The pressure plate 212 is located below the support platform 120.

[0050] In this application, the support platform 120 serves as the mounting carrier for the drive component 211, fixed to the support frame 100, providing a stable support foundation for the drive component 211 and ensuring that its position does not shift when outputting driving force. The drive part of the drive component 211 (such as a piston rod, push rod, etc.) passes through the clearance hole on the support platform 120 and connects to the pressure plate 212 located below the support platform 120. When the drive component 211 receives a trigger signal, its drive part performs a vertical extension and retraction action through the clearance hole. When clamping is required, the drive part extends downward, driving the pressure plate 212 to descend along the guide direction of the support frame 100 until it abuts against the second clamping assembly 220. When releasing is required, the drive part retracts upward, driving the pressure plate 212 to rise and reset through the clearance hole, returning to the initial position below the support platform 120.

[0051] Specifically, the support platform 120 provides a rigid mounting base for the drive component 211, preventing vibration or displacement from the drive component 211 being directly mounted on the support frame 100, thus ensuring stable transmission of driving force. Simultaneously, the drive unit connects to the pressure plate 212 via clearance holes, further enhancing the stability of the pressure plate 212's lifting and lowering movements. With the drive component 211 mounted on the support platform 120 and the pressure plate 212 located below it, the structure of the first clamping assembly 210 is arranged in vertical layers, avoiding spatial interference between the drive component and the tool placement section 110 below and the second clamping assembly 220. The support platform 120 provides a certain degree of shielding and protection for the drive component 211 located above it.

[0052] like Figures 1 to 3 As shown, in some embodiments, the pressure plate 212 is provided with a clearance notch 2121 for the clearance clamping part 221.

[0053] In this application, when the clamping part 221 of the second clamping assembly 220 moves toward the water booster 400 and completes the clamping action, the clamping part 221 protrudes from the surface of the tool placement part 110. At this time, the pressure plate 212 of the first clamping assembly 210 descends under the drive of the drive member 211. If the pressure plate 212 is a complete plane, its edge or middle may mechanically interfere with the clamping part 221, preventing the pressure plate 212 from descending to the preset clamping position. The shape and position of the clearance notch 2121 are precisely matched with the shape and movement trajectory of the clamping part 221. When the pressure plate 212 descends, the clamping part 221 can be precisely embedded in the clearance notch 2121, so that the pressure plate 212 can smoothly pass through the area where the clamping part 221 is located and accurately abut against the non-clamping part (such as the fixed base) of the second clamping assembly 220 or the top surface of the water booster 400, realizing the vertical clamping action.

[0054] Specifically, the avoidance notch 2121 solves the problem of interference between the pressure plate 212 and the clamping part 221, avoiding structural damage or operational failure caused by component collisions, and improving the reliability of the clamping mechanism 200. It also prevents hard collisions between the pressure plate 212 and the clamping part 221 during movement, extending the service life of the equipment.

[0055] like Figures 1 to 3 As shown, in some embodiments, the clamping part 221 includes a plurality of grippers 2211, and a buffer assembly 300 is provided on the grippers 2211. The buffer assembly 300 is used to abut against the sealing plate of the water booster 400.

[0056] In this application, when the second clamping assembly 220 initiates its clamping action, multiple grippers 2211 simultaneously approach the water booster 400, forming an encirclement from different sides (such as a circumferentially evenly distributed position). Due to the multi-grip structure 2211, stable clamping of the water booster 400 can be achieved through distributed force, avoiding the center of gravity shift that might occur with single-point clamping. When the grippers 2211 contact the water booster 400, the buffer assembly 300 on the grippers 2211, as a direct contact component, first abuts against the sealing plate of the water booster 400. The buffer assembly 300 will adaptively deform or buffer stroke according to the contact pressure. During the continuous tightening of the grippers 2211, the buffer assembly 300 absorbs the impact of the clamping force through its own elastic deformation, preventing instantaneous compression of the sealing plate by rigid contact. When releasing the clamp, the multiple grippers 2211 move synchronously in the opposite direction, and the buffer assembly 300 disengages from the sealing plate along with the grippers, improving the reliability of the clamping structure.

[0057] Specifically, the distributed arrangement of multiple grippers 2211 can apply clamping force to the water booster 400 from multiple directions, making the force on the sealing plate and the entire workpiece more uniform and reducing the tilting or displacement of the workpiece caused by unilateral force. The buffer assembly 300 transforms the rigid clamping of the grippers 2211 into flexible contact through elastic buffering, avoiding scratches, deformation or sealing performance failure of the sealing plate due to instantaneous rigid compression.

[0058] like Figure 4 As shown, in some embodiments, the buffer assembly 300 includes a clamping screw 310, a buffer pad 320, and a locking screw 330. The clamping screw 310 passes through the clamping jaw 2211 and the buffer pad 320 in sequence. The end of the clamping screw 310 is provided with a threaded hole. The locking screw 330 is threadedly engaged with the threaded hole and abuts against the buffer pad 320 to fix the buffer pad 320. The buffer pad 320 is used to abut against the sealing plate of the water booster 400.

[0059] In this application, the clamping screw 310 passes sequentially through the pre-set through hole of the clamp 2211 and the mounting hole of the buffer pad 320, so that the buffer pad 320 is tightly attached to the inner side of the clamp 2211. At this time, the threaded hole at the end of the clamping screw 310 is exposed on the outer side of the buffer pad 320. The locking screw 330 is screwed in through the thread engagement with the threaded hole until it tightly abuts against the surface of the buffer pad 320. The buffer pad 320 is firmly fixed between the clamping screw 310 and the clamp 2211 by axial pressure, forming a rigid connection of "clamp - clamping screw - buffer pad - locking screw". When the clamp 2211 approaches the water booster 400, the buffer pad 320 (usually made of elastic materials such as rubber or silicone) is the first to contact the surface of the sealing plate as a direct contact component. As the gripper 2211 continues to tighten, the sealing plate applies reverse pressure to the buffer pad 320, forcing the buffer pad 320 to undergo elastic deformation. The degree of deformation increases with the increase of the clamping force. The material's own elasticity absorbs the impact force during the clamping process, preventing the rigid force of the gripper 2211 from acting directly on the sealing plate.

[0060] Specifically, the tightening action of the locking screw 330 ensures that the buffer pad 320 will not shift relative to the clamping screw 310 when deformed under force, so that the deformation of the buffer pad 320 is always controlled by the clamping action of the gripper 2211. At the same time, the rigid connection between the clamping screw 310 and the gripper 2211 stably transmits the clamping force to the buffer pad 320, ensuring that the buffer pad 320 will not fall out of the installation position due to excessive force, and realizing the force transmission method between the rigid clamping frame and the flexible contact interface through the elastic deformation of the buffer pad.

[0061] like Figures 1 to 3 As shown, in some embodiments, the second clamping assembly 220 includes a chuck 222 and a rotating member. The chuck 222 is disposed on the tool placement portion 110, the clamping portion 221 is movably disposed on the chuck 222, and the rotating member is rotatably disposed on the chuck 222. The rotating member drives the clamping portion 221 to move radially along the chuck 222 so that the clamping portion 221 is used to clamp or release the water booster 400.

[0062] In this application, the chuck 222 is fixed to the tool placement section 110, and the clamping sections 221 (such as multiple jaws 2211) are distributed circumferentially around the chuck 222 and can move along guide rails or grooves on the chuck surface. A rotating component is rotatably connected to the chuck 222 and forms a transmission engagement with the clamping sections 221. When the water booster 400 needs to be clamped, an external force drives the rotating component to rotate, and its rotational motion is converted into radial movement of the clamping sections 221 through a transmission structure. Multiple clamping sections 221 synchronously contract radially, ultimately enclosing and clamping the sealing plate of the water booster 400 circumferentially. When it is necessary to release the clamp, the rotating component rotates in the opposite direction, driving the clamping sections 221 to move radially outward along the chuck 222 through the transmission structure. Multiple clamping sections 221 synchronously open, releasing the constraint on the water booster 400, allowing it to be removed from the tool placement section 110.

[0063] Specifically, the rotational motion of the rotating component synchronously drives all clamping parts 221 to move radially via mechanical transmission, ensuring that the displacement of multiple clamping parts 221 is consistent and avoiding uneven force or workpiece displacement caused by the delayed action of a single clamping part. The rotation angle of the rotating component is linearly related to the moving distance of the clamping part 221. By controlling the rotation amount of the rotating component, the contraction amplitude of the clamping part 221 can be precisely adjusted, thereby controlling the magnitude of the clamping force.

[0064] In some embodiments, a first bevel gear and a second bevel gear are provided within the chuck 222. A rotating member extends into the first bevel gear and drives it to rotate. The first bevel gear meshes with the second bevel gear. The second bevel gear has a first planar thread, and the clamping portion 221 has a second planar thread that mates with the first planar thread. The second bevel gear is configured such that when the rotating member drives the first bevel gear to rotate, the second bevel gear rotates, driving the clamping portion 221 to move radially along the chuck 222, so that the clamping portion 221 is used to clamp or release the water booster 400.

[0065] In this application, a rotating component extends into and is fixed to the inner hole of the first bevel gear. When the rotating component rotates, it directly drives the first bevel gear to rotate synchronously. Since the first and second bevel gears mesh with each other, the rotational motion of the first bevel gear is transmitted to the second bevel gear through tooth surface meshing, achieving a 90° change in the direction of power; that is, the axial rotation of the rotating component is converted into the radial rotation of the second bevel gear. A first planar thread is machined on the end face of the second bevel gear, while a second planar thread matching the first planar thread is provided at the bottom of the clamping part 221. When the second bevel gear rotates under the drive of the first bevel gear, the first and second planar threads generate relative motion through tooth surface meshing. Because the clamping part 221 is constrained by the guide rail of the chuck 222, the axial force generated by the thread meshing will push the clamping part 221 to move linearly along the radial direction of the chuck 222. When the rotating component rotates in the forward direction, the first bevel gear drives the second bevel gear to rotate in the forward direction, and the first planar thread drives the second planar thread of the clamping part 221, causing the multiple clamping parts 221 to retract synchronously in the radial direction, thus completing the clamping of the water booster 400. When the rotating component rotates in the reverse direction, the transmission direction is reversed, and the clamping parts 221 open synchronously in the radial direction, releasing the clamping.

[0066] Specifically, the bevel gear meshing has a small transmission clearance, and combined with the helical guidance of the planar thread, the displacement adjustment of the clamping part 221 can be achieved. Simultaneously, multiple clamping parts are driven by the same planar thread, ensuring completely consistent radial movement and preventing eccentricity of the water booster 400 due to uneven force. The first and second planar threads have a self-locking function; after stopping the drive of the rotating component, the static friction of the thread meshing prevents the clamping part 221 from moving in the opposite direction, keeping the clamping force stable without requiring continuous power supply, thus saving energy and preventing accidental loosening. Furthermore, the bevel gear drive has high force transmission efficiency, efficiently converting the driving force of the rotating component into clamping force.

[0067] In some embodiments, the rotating component is a rotary wrench, and a mounting hole is provided in the first bevel gear, with the rotary wrench engaging with the mounting hole.

[0068] In this application, by engaging the rotary wrench with the mounting hole in the first bevel gear, the rotary wrench can drive the first bevel gear to rotate when it is turned, thereby moving the clamping part 221. Afterward, by disengaging the rotary wrench from the mounting hole, the clamping part 221 can be kept in the clamping position.

[0069] like Figures 1 to 3 As shown, in some embodiments, the tool placement part 110 is a support plate 111.

[0070] In this application, the support plate 111 provides support for the second clamping assembly 220. The support plate 111 possesses sufficient rigidity and strength to stably bear the weight of various tools, preventing structural deformation or damage caused by tool placement, ensuring tool stability after placement, and reducing the risk of tool slippage. The support plate 111 provides a stable placement surface, adaptable to tools of different shapes and sizes, ensuring a secure connection.

[0072] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
