Description

Technical Field

[0001] This utility model relates to the field of valve body welding manufacturing, specifically to a guide rail rib welding fixture. Background Technology

[0002] Currently, the guide rail ribs of flat gate valve bodies are generally cast, integrally formed with the valve body. In subsequent processes, the guide rail ribs are machined to limit and match the gate. The guide rail ribs guide the gate on both sides in the width direction and are usually relatively short. For elongated guide rail ribs, the overall length is much longer. Milling the guide rail ribs is inefficient and costly. Since the valve body's guide rail ribs need to withstand fluid pressure, if the guide rail ribs are improperly tilted during manufacturing, the gate will also tilt during operation, causing poor contact between the sealing ring on the retainer and the gate sealing surface, resulting in leakage. Therefore, it is necessary to ensure the connection strength and accuracy between the guide rail ribs and the valve body. Welding can be used to fix the elongated guide rail ribs to the valve body to achieve the desired reliable connection. However, currently, there is a lack of a tooling structure that can provide precise positioning during the welding and fixing of the guide rail ribs to the valve body, ensuring proper alignment of the guide rail ribs. Utility Model Content

[0003] In view of this, the present invention provides a guide rail rib welding fixture to ensure that the guide rail rib is accurately positioned when it is welded and fixed to the valve body, so as to ensure the proper alignment of the guide rail rib.

[0004] This utility model provides a welding fixture for guide rail ribs, including:

[0005] A retainer, suitable for positioning and connecting with the seat ring hole of the valve body;

[0006] At least two locking blocks are disposed on the side of the retainer facing the guide rail rib, each locking block having a locking position for loading the guide rail rib; any two locking blocks are spaced apart.

[0007] The first locking assembly is detachably and relatively positioned to connect the retainer and the locking block;

[0008] And at least one stop member, the stop member and the locking block are detachably connected, the stop end of the stop member is disposed toward the locking position to abut against the action guide rib.

[0009] Beneficial effects: By connecting the retainer to the seat ring hole of the valve body, the seat ring hole provides positioning and a precise reference for subsequent welding operations, ensuring accurate positioning of the tooling on the valve body and guaranteeing the accuracy of the welding position; the locking position is used to load the guide rail rib, and any two locking blocks are spaced apart to load the same guide rail rib. This arrangement allows the guide rail rib to be stably placed in the locking position of the locking block, preventing displacement of the guide rail rib during welding. The locking block and the reinforcing rib are set in parallel, thereby ensuring accurate alignment of the guide rail rib and the valve body and improving welding quality; the first locking assembly provides a detachable relative positioning connection between the retainer and the locking block, as well as a detachable connection between the stop and the locking block, making the entire tooling structure more flexible, easy to install and disassemble, and also easy to adjust and replace various parts of the tooling, improving the service life and versatility of the tooling, and also helping to improve assembly efficiency.

[0010] In some alternative embodiments, the first locking assembly includes a connecting pin and a fastener, the connecting end of the connecting pin passing through the locking block to be fixedly connected to the retainer, the connecting pin being detachably configured with the locking block and the retainer, the stopping end of the fastener passing through the locking block to abut against and limit the retainer, and the fastener being detachably configured with the locking block and the retainer.

[0011] Beneficial effects: The connecting pin passes through the locking block and is fixedly connected to the retainer, and the fastening end of the fastener passes through the locking block and abuts against the retainer for limiting. This double fixing method enhances the connection stability between the locking block and the retainer, preventing the locking block from loosening or shifting during welding, thereby ensuring the stability of the entire tooling and improving welding quality. The connecting pin and fastener, along with the locking block and retainer, are all detachable, allowing for convenient and quick disassembly and reinstallation when adjustments, replacements, or repairs are needed. This improves the maintenance efficiency and flexibility of the tooling and reduces production downtime caused by tooling failures. This detachable connection method allows for the rapid installation and disassembly of various components as needed during assembly, improving assembly efficiency. It also facilitates rapid debugging and calibration of the tooling, ensuring its accuracy and performance.

[0012] In some optional embodiments, the retainer is provided with a first fixing hole and a second fixing hole, the first fixing hole being fixedly connected to the connecting end of the connecting pin, and the second fixing hole being limited and abutting against the fastening end of the fastener; the locking block is provided with a first locking hole and a second locking hole, the first locking hole being connected to the connecting pin, and the second locking hole being connected to the fastener; the first fixing hole and the first locking hole are coaxially arranged, and the second fixing hole and the second locking hole are coaxially arranged.

[0013] Beneficial effects: By setting a first fixing hole, a second fixing hole, a first locking hole, and a second locking hole on the retainer and locking block respectively, and aligning the first fixing hole and the first locking hole coaxially, and the second fixing hole and the second locking hole coaxially, precise matching between the connecting pin and fastener and the retainer and locking block can be achieved, further improving the positioning accuracy of the tooling and ensuring the accurate position of the locking block on the retainer, thereby guaranteeing the welding accuracy of the guide rail rib; furthermore, this coaxial arrangement allows the connecting pin and fastener to connect more stably with the retainer and locking block, enhancing the structural stability of the entire tooling, reducing component loosening or displacement caused by vibration and other factors during welding, improving welding quality and tooling reliability; the coaxial hole arrangement facilitates rapid hole alignment and installation during assembly, improving processing and assembly efficiency and reducing production costs.

[0014] In some optional embodiments, four locking blocks are provided, and each locking block is correspondingly configured with two sets of the first locking components, with the two sets of the first locking components being staggered at intervals.

[0015] Beneficial effects: The four locking blocks, along with two sets of first locking components, are staggered at intervals, which enables the fixture to stably fix the guide rail ribs in multiple directions. This enhances the clamping force and stability of the fixture on the guide rail ribs, preventing the guide rail ribs from shaking or shifting during welding, thereby improving welding quality.

[0016] In some alternative embodiments, the retainer is configured as a disc-shaped structure, with all the first locking components centrally symmetrically distributed in the retainer.

[0017] Beneficial effects: The retainer is designed as a disc-shaped structure, and all the first locking components are centrally symmetrically distributed on the retainer. This structural design makes the overall structure of the tooling more compact and reasonable, and can better adapt to valve bodies and guide rails of different shapes and sizes, improving the versatility and applicability of the tooling, while also facilitating the processing and manufacturing of the tooling.

[0018] In some alternative embodiments, the locking block is provided with a locking groove, which is configured as a recessed groove structure, and the recessed groove structure constitutes the locking position.

[0019] Beneficial effects: The recessed groove structure of the locking groove provides a stable placement position for the guide rail rib, allowing it to be accurately embedded in the locking groove. This improves the alignment accuracy between the guide rail rib and the locking block, ensuring the accurate positioning of the guide rail rib during welding and improving welding quality. Furthermore, the locking groove structure of the recessed groove structure can better match the shape of the guide rail rib, increasing the contact area between the locking block and the guide rail rib. This enhances the clamping stability of the locking block on the guide rail rib, preventing the guide rail rib from loosening or shifting during welding and ensuring the smooth progress of the welding process.

[0020] In some alternative embodiments, the locking block is bent, the first locking assembly is disposed on one side of the bent locking block to connect and align the retainer, and the locking position is disposed on the other side of the bent locking block to load the guide rail rib.

[0021] Beneficial effects: The bending design of the locking block makes the connection between the first locking component and the retainer more stable, and also makes the contact between the locking position and the guide rail rib tighter, enhancing the clamping force and stability of the tooling on the guide rail rib, preventing the guide rail rib from shaking or shifting during welding, improving the stability of the tooling, and thus improving welding quality. In addition, the bending design makes the structure of the locking block more compact, better adapting to the overall layout of the tooling, saving space, and also helping to improve the structural strength and rigidity of the tooling, enhancing its durability. Placing the first locking component on one side of the bending of the locking block facilitates quick connection and fixation during assembly, improving assembly efficiency. At the same time, placing the locking position on the other side of the bending of the locking block makes it easier to place and fix the guide rail rib, reducing assembly time and labor costs.

[0022] In some optional embodiments, the locking block is provided with two third locking holes, which are connected to the stop member, and the axial extension directions of the two third locking holes are arranged perpendicularly or perpendicularly to each other.

[0023] Beneficial effects: The two third locking holes are arranged perpendicularly or in opposite directions, allowing the locking element to clamp and fix the guide rail rib from two different directions. This more precisely restricts the position of the guide rail rib and reduces its degrees of freedom in various directions. Because the clamping forces are in different directions, they complement each other, forming a more stable clamping system. This effectively prevents the guide rail rib from shaking or shifting during welding, enhancing positioning accuracy, improving clamping stability, and increasing alignment accuracy and welding quality during the welding stage. Furthermore, this design makes full use of space, allowing the locking block to achieve more effective clamping within a limited space. It also simplifies the tooling structure, reduces additional clamping components, and makes the entire tooling more compact and concise, facilitating processing and manufacturing.

[0024] In some alternative embodiments, the guide rail welding fixture further includes a pull plate and a second locking assembly, the pull plate being adapted to abut against the lateral end face of the valve body, and the second locking assembly being detachably connected to the pull plate and the retainer to relative position the valve body, the pull plate, and the retainer.

[0025] Beneficial effects: The pull plate abuts against the side end face of the valve body, providing an additional positioning reference for the tooling. Connecting the pull plate to the retainer via the second locking assembly allows for precise adjustment and fixation of the relative position of the tooling and the valve body, thereby improving the positioning accuracy of the tooling on the valve body and ensuring the accuracy of the welding operation. Furthermore, the abutment between the pull plate and the side end face of the valve body increases the contact area and friction between the tooling and the valve body, thus improving the stability of the tooling during the welding process. This helps reduce displacement of the tooling due to vibration and other factors during welding, ensuring weld quality.

[0026] In some optional embodiments, the second locking assembly includes a screw and a nut. One end of the screw is fixedly connected to the retainer, and the other end of the screw is fixedly connected to the pull plate via the nut. The nut is located on the side of the pull plate opposite to the retainer. The pull plate has a connecting hole for the screw to pass through, and the retainer has a third fixing hole, which is fixedly connected to one end of the screw.

[0027] Beneficial effects: The combined use of the screw and nut components enables precise adjustment of the position between the pull plate and the retainer. By rotating the nut, the distance and angle between the pull plate and the retainer can be fine-tuned, thus achieving precise alignment between the tooling and the valve body. The fixed connection between the screw and the retainer, and the fixed connection between the nut and the pull plate, form a robust connection structure. This structure can withstand significant tensile and compressive forces, ensuring a stable connection between the pull plate and the retainer during welding and preventing loosening or displacement of components due to external forces. The screw and nut components have a simple structure, are easy to operate, and are readily processed and manufactured. Simultaneously, this connection method facilitates the maintenance and replacement of the tooling, reducing maintenance costs and time. Furthermore, the nut is located on the side of the pull plate away from the retainer, making it easier for operators to access and improving assembly efficiency.

[0028] In some alternative implementations, two sets of the second locking components are symmetrically arranged.

[0029] Beneficial effects: The two sets of second locking components allow for fixation of the pull plate and retainer from two different directions, forming a more stable connection system. This dual-fixation method effectively disperses and bears external forces, reducing component deformation or damage caused by single-point stress, thereby improving the overall stability of the tooling and ensuring smooth welding. The two sets of second locking components can simultaneously adjust and fix the positions of the pull plate and retainer, further improving the relative positioning accuracy of the tooling and valve body. Precise adjustment of the two sets of locking components ensures a more accurate position of the tooling on the valve body, improving welding quality. Attached Figure Description

[0044] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0045] According to an embodiment of this utility model, in one aspect, a guide rail rib welding fixture is provided, see [link to relevant documentation]. Figures 1 to 3 The guide rail rib welding fixture includes a retainer 201, a locking block 202, a first locking assembly, and a stop member 208. The retainer 201 is adapted to be connected to the seat ring hole of the valve body 101 for limiting.

[0046] In this embodiment, there are one or more locking blocks 202. The locking blocks 202 are located on the side of the fixture 201 facing the guide rail rib 103, and any two locking blocks 202 are spaced apart. The first locking assembly is detachably positioned to connect the fixture 201 and the locking blocks 202.

[0047] The locking block 202 has a locking position for loading the guide rail rib 103; for example, two locking blocks 202 spaced apart can jointly load the same guide rail rib 103. At least one stop member 208 is provided, and the stop member 208 and the locking block 202 are detachably connected. The stop end of the stop member 208 is positioned facing the locking position to abut against the guide rail rib 103.

[0048] The guide rail rib welding fixture provided in this embodiment connects the retainer 201 to the seat ring hole of the valve body 101 for positioning. The seat ring hole provides a precise reference for subsequent welding operations, ensuring accurate positioning of the fixture on the valve body 101 and guaranteeing the accuracy of the welding position. The locking position is used to load the guide rail rib 103, and any two locking blocks 202 are spaced apart to load the same guide rail rib 103. This arrangement ensures that the guide rail rib 103 is stably placed in the locking position of the locking block 202, preventing the guide rail rib 103 from being damaged during welding. During the welding process, the locking block 202 and the reinforcing rib are set in parallel to ensure the accurate alignment of the guide rail rib 103 and the valve body 101, thus improving the welding quality. The first locking assembly is detachably connected to the fixing device 201 and the locking block 202, and the stop part 208 is detachably connected to the locking block 202, making the structure of the entire tooling more flexible, easy to install and disassemble, and also easy to adjust and replace the various parts of the tooling, improving the service life and versatility of the tooling, and also helping to improve assembly efficiency.

[0049] In one embodiment, see Figure 2 and Figure 5 The locking block 202 is bent, and the first locking component is located on one side of the bend of the locking block 202 to connect to the alignment fixture 201. The locking position is located on the other side of the bend of the locking block 202 to load the guide rail rib 103.

[0050] The guide rail rib welding fixture provided in this embodiment features a bent locking block 202, which makes the connection between the first locking component and the retainer 201 more stable. It also ensures a tighter contact between the locking position and the guide rail rib 103, enhancing the clamping force and stability of the fixture on the guide rail rib 103. This prevents the guide rail rib 103 from shaking or shifting during welding, improving fixture stability and thus welding quality. Furthermore, the bent design makes the locking block 202 more compact, better adapting to the overall layout of the fixture, saving space, and also improving the structural strength and rigidity of the fixture, enhancing its durability. Positioning the first locking component on one side of the bent locking block 202 facilitates quick connection and fixation during assembly, improving assembly efficiency. Simultaneously, positioning the locking position on the other side of the bent locking block 202 allows for easier placement and fixation of the guide rail rib 103, reducing assembly time and labor costs.

[0051] In one embodiment, see Figure 2The first locking assembly includes a connecting pin 203 and a fastener 204.

[0052] The guide rail rib welding fixture provided in this embodiment has a connecting pin 203 that passes through a locking block 202 and is fixedly connected to a retainer 201. The fastening end of the fastener 204 also passes through the locking block 202 and abuts against the retainer 201 for limiting. This dual fixing method enhances the connection stability between the locking block 202 and the retainer 201, preventing the locking block 202 from loosening or shifting during welding, thus ensuring the stability of the entire fixture and improving welding quality. The connecting pin 203 and fastener 204 are detachable from both the locking block 202 and the retainer 201, allowing for convenient and quick disassembly and reinstallation when adjustments, replacements, or repairs are needed. This improves the maintenance efficiency and flexibility of the fixture and reduces production downtime caused by fixture malfunctions. This detachable connection method allows for rapid installation and disassembly of various components during assembly, improving assembly efficiency. It also facilitates rapid debugging and calibration of the fixture, ensuring its accuracy and performance.

[0053] In one embodiment, see Figure 4 and Figure 5 The fastener 201 has a first fixing hole 2011 and a second fixing hole 2012.

This structural design makes the overall structure of the fixture more compact and reasonable, and can better adapt to valve bodies 101 and guide rail ribs 103 of different shapes and sizes, improving the versatility and applicability of the fixture, while also facilitating the processing and manufacturing of the fixture.

[0059] In one embodiment, see Figure 5 The locking block 202 is provided with a locking groove 2023, which is configured as a recessed groove structure, and the recessed groove structure constitutes a locking position.

[0060] The guide rail rib welding fixture provided in this embodiment has a recessed groove structure in the locking groove 2023 that provides a stable placement position for the guide rail rib 103, allowing the guide rail rib 103 to be accurately embedded in the locking groove 2023. This improves the alignment accuracy between the guide rail rib 103 and the locking block 202, ensuring the accurate position of the guide rail rib 103 during the welding process and improving the welding quality. Furthermore, the locking groove 2023 with the recessed groove structure can better match the shape of the guide rail rib 103, increasing the contact area between the locking block 202 and the guide rail rib 103. This enhances the clamping stability of the locking block 202 on the guide rail rib 103, preventing the guide rail rib 103 from loosening or shifting during the welding process and ensuring the smooth progress of the welding process.

[0061] In one embodiment, see Figure 5 The locking block 202 is provided with two third locking holes 2024, which are connected to the stop member 208. The axial extension directions of the two third locking holes 2024 are either perpendicular or perpendicular to each other.

[0062] The guide rail rib welding fixture provided in this embodiment has two third locking holes 2024 whose axial extension directions are either perpendicular or perpendicular to each other. This structure allows the locking member 208 to clamp and fix the guide rail rib 103 from two different directions, more precisely restricting the position of the guide rail rib 103 and reducing its degrees of freedom in various directions. Because the clamping forces are in different directions, they can complement each other, forming a more stable clamping system, thereby effectively preventing the guide rail rib 103 from shaking or shifting during welding, enhancing positioning accuracy, improving clamping stability, and improving alignment accuracy and welding quality during the welding stage. Furthermore, this design makes full use of space, allowing the locking block 202 to achieve a more effective clamping function within a limited space. At the same time, it simplifies the fixture structure, reduces additional clamping components, making the entire fixture more compact and concise, and facilitating processing and manufacturing.

[0063] In one embodiment, see Figure 1 and Figure 3 The guide rail welding fixture also includes a pull plate 205 and a second locking assembly. The pull plate 205 is adapted to abut against the lateral end face of the valve body 101. The second locking assembly is detachably connected to the pull plate 205 and the retainer 201 so as to relative position the valve body 101, the pull plate 205 and the retainer 201.

[0064] The guide rail rib welding fixture provided in this embodiment has a pull plate 205 that abuts against the side end face of the valve body 101, providing an additional positioning reference for the fixture. Connecting the pull plate 205 to the retainer 201 via the second locking assembly allows for precise adjustment and fixation of the relative position between the fixture and the valve body 101, thereby improving the positioning accuracy of the fixture on the valve body 101 and ensuring the accuracy of the welding operation. Furthermore, the abutment between the pull plate 205 and the side end face of the valve body 101 increases the contact area and friction between the fixture and the valve body 101, thus improving the stability of the fixture during the welding process. This helps reduce displacement of the fixture due to vibration and other factors during welding, ensuring welding quality.

[0065] In one embodiment, see Figure 1 , Figure 4 and Figure 6 The second locking assembly includes a screw 206 and a nut 207. One end of the screw 206 is fixedly connected to the retainer 201, and the other end of the screw 206 is fixedly connected to the pull plate 205 through the nut 207. The nut 207 is located on the side of the pull plate 205 away from the retainer 201. The pull plate 205 is provided with a connecting hole 2051 for the screw 206 to pass through. The retainer 201 is provided with a third fixing hole 2013, which is fixedly connected to one end of the screw 206.

[0066] The guide rail welding fixture provided in this embodiment, through the cooperation of the screw 206 and the nut 207, enables precise adjustment of the position between the pull plate 205 and the fixture 201. By rotating the nut 207, the distance and angle between the pull plate 205 and the fixture 201 can be finely adjusted, thereby achieving precise alignment between the fixture and the valve body 101. The fixed connection between the screw 206 and the fixture 201, and the fixed connection between the nut 207 and the pull plate 205, form a robust connection structure. This structure can withstand significant tensile and compressive forces, ensuring a stable connection between the pull plate 205 and the fixture 201 during the welding process and preventing loosening or displacement of components due to external forces. The screw 206 and the nut 207 have a simple structure, are easy to operate, and are easy to process and manufacture. Simultaneously, this connection method facilitates the maintenance and replacement of the fixture, reducing maintenance costs and time. In addition, the nut 207 is located on the side of the pull plate 205 away from the retainer 201, which makes it easier for operators to operate and improves the efficiency of work assembly.

[0067] In one embodiment, two sets of second locking components are symmetrically arranged. These two sets of second locking components can fix the pull plate 205 and the retainer 201 from two different directions, forming a more stable connection system. This dual-fixing method effectively disperses and bears external forces, reducing component deformation or damage caused by single-point force, thereby improving the overall stability of the tooling and ensuring the smooth progress of the welding process. The two sets of second locking components can simultaneously adjust and fix the positions of the pull plate 205 and the retainer 201, further improving the relative positioning accuracy of the tooling and the valve body 101. By precisely adjusting the two sets of locking components, the position of the tooling on the valve body 101 can be ensured to be more accurate, improving the welding quality.

[0068] In the specific operational process:

[0069] 1. The retainer 201 is positioned by the bottom plane of the step in the seat ring hole of the valve body 101 and the inner hole;

[0070] 2. Specifically, the reinforcing rib is fixed by locking block 202, and the locking block 202 is parallel to the reinforcing rib;

[0071] 3. The locking block 202 can be wire-cut to ensure that the groove of the locking position is parallel to the plane of the reinforcing rib;

[0072] 4. The retainer 201 and the locking block 202 are fixed by pins and screws.

[0073] 5. The pull plate 205 and the retainer 201 on the end face of the valve body 101 are locked and fixed by screws and nuts.

[0074] 6. Welding sequence: first spot weld, then weld around the opening, gradually remove the tooling, and then weld around the inside of the cavity.
