Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a general-purpose valve clamp. Background Technology

[0002] In the production of valves, such as common faucet valves, clamps are used to hold them for easier processing. Existing technology often uses a type of clamp called a hafn clamp to hold valves. This type of clamp requires the operator to manually press the two clamping arms together to secure the valve, which is cumbersome and results in low production efficiency.

[0003] To address the aforementioned problems, the inventor previously filed a patent providing an improved portable valve body clamp (application number: CN202220434101.X). Several sets of clamping devices are mounted on the upper and lower surfaces of the base. Each clamping device includes a fixed part, a driving component, and a movable part. The movable part is positioned within a groove on the base. The driving component pushes the movable part along the groove to adjust the clamping distance between the fixed and movable parts, thereby clamping the valve. By moving the movable part within the groove towards the fixed part to clamp the valve, the defect of traditional clamps requiring manual clamping of the clamping arms is effectively solved. Furthermore, the driving component's movement of the movable part towards the fixed part ensures clamping tightness and facilitates adjustment of the clamping distance, making the process convenient and quick.

[0004] In the spirit of continuous improvement, the inventors have discovered the following issues requiring optimization in the above-mentioned solution: The clamping device clamps the valve by forming mutual clamping grooves through recesses on opposite sides of the fixed and movable parts. This limits the applicability of the clamp to similar valves that conform to the shape of the clamping grooves, resulting in low versatility. If it is necessary to clamp workpieces with other structures, both the movable and fixed parts need to be disassembled and redesigned for replacement. This leads to a higher manufacturing load and material cost for the clamp, as well as a longer product debugging time. Summary of the Invention

[0005] In view of the aforementioned defects or deficiencies in the prior art, it is desirable to provide a general-purpose valve fixture in which the clamping element is detachably connected to the moving part and the fixed part. This allows the valve fixture to be used with workpieces of different structures simply by machining the clamping groove of the clamping element according to the shape of the workpiece, and by replacing the appropriate clamping element with the one required for the workpiece. This improves the versatility of the valve fixture, enhances design efficiency, reduces the manufacturing load and material costs, and shortens the development cycle.

[0006] The effect of this utility model is achieved as follows:

[0007] This application provides a general-purpose valve clamp, including a bridge plate. Several clamping assemblies are mounted on the surface of the bridge plate. Each clamping assembly includes a movable part, a pushing assembly, a fixed part, and clamping members. The movable part is slidably connected to the bridge plate via a sliding mechanism. Two symmetrical clamping members are detachably disposed on the movable part and the fixed part, respectively. A clamping groove is recessed on one side of each clamping member, and the clamping groove is configured to conform to the side wall of the workpiece. The pushing assembly is configured to push the movable part towards the fixed part to adjust the clamping distance between the two clamping members to clamp the workpiece. Each set of clamping assemblies includes two fixed parts, left and right. The pushing assembly is disposed between the two fixed parts, and movable parts are connected to both sides of the pushing assembly. The pushing assembly simultaneously pushes the two movable parts on both sides towards the fixed parts.

[0008] Furthermore, the clamping component is detachably connected to the movable part and the fixed part via a threaded connection. This not only ensures high connection strength between the clamping component and the movable and fixed parts, but also makes the installation and removal of the clamping component more convenient.

[0009] Furthermore, a first positioning mechanism is provided between the clamping component, the movable part, and the fixed part. The positioning mechanism includes a first positioning protrusion and a first positioning groove that engage with each other. The first positioning protrusion is disposed on the clamping component, the movable part, and the fixed part, respectively, to form the first positioning groove. This makes the positioning operation during clamping component installation more convenient.

[0010] Furthermore, the jacking assembly includes a jacking part and an adjusting component. The jacking part has a vertically perforated connecting hole. From top to bottom, the adjusting component includes a screwing part, a connecting part, and a threaded part. The connecting part is engaged with the jacking part through the connecting hole, and the diameters of the screwing part and the threaded part are larger than the connecting hole, thus fixing the adjusting component and the jacking part relatively in the vertical direction. The threaded part has an external thread and is threadedly connected to the bridge plate. The end face of the jacking part near the movable part and / or the end face of the movable part near the jacking part are inclined. This allows the adjusting component to drive the jacking part to slide up and down when the screwing part is screwed, thereby pushing the movable part and forcing it to slide left and right along the inclined surface. The transmission effect is stable, the adjustment operation is very simple, and the clamping effect of the valve clamp is relatively stable.

[0011] Furthermore, the opposing end faces of the movable part and the pushing part are both inclined in the same direction. This allows the movable part and the pushing part to fit together more closely, resulting in a stronger connection. When the pushing part pushes the movable part vertically, the movable part can slide more stably in the horizontal direction along the inclination direction of the two inclined surfaces, thus making the transmission process between the movable part and the pushing part more stable.

[0012] Furthermore, a second positioning mechanism is provided between the opposing end faces of the movable part and the pushing part. The second positioning mechanism includes a second positioning protrusion and a second positioning groove that engage with each other. The second positioning protrusion is located in one of the movable part and the pushing part, and the second positioning groove is located in the other. When the pushing part pushes the movable part to slide in a left-right direction, the second positioning protrusion slides within the second positioning groove. This enhances the connection strength between the movable part and the pushing part, effectively preventing the movable part from shifting during sliding, thereby improving the stability of the valve clamp.

[0013] Furthermore, the connecting hole has an opening on one side in the horizontal direction, allowing the connecting part to snap into the connecting hole through this opening. This makes the installation and disassembly of the adjusting part and the pushing part more convenient.

[0014] Furthermore, several vertical first limiting members are connected to the bridge plate. Both the front and rear ends of the pushing part are stopped by the first limiting members, so that the pushing part and the bridge plate remain relatively fixed in the front-rear direction. This prevents the pushing part from rotating relative to the bridge plate, thereby avoiding the pushing part from shifting and further improving the stability of the valve clamp.

[0015] Furthermore, the bridge plate is provided with several second limiting members, and each movable part has a second limiting member attached to its front and rear ends. The sliding mechanism includes a sliding part and a sliding limiting groove. The sliding part or the second limiting member has a sliding limiting groove that extends from left to right. The sliding part is correspondingly disposed in another of the sliding part and the second limiting member. The sliding part slides left and right along the sliding limiting groove, thereby allowing the movable part to slide left and right relative to the bridge plate. This improves the connection strength between the movable part and the bridge plate, resulting in better stability.

[0016] The general-purpose valve clamp provided in this application clamps the workpiece between two clamping members by pushing the movable part towards the fixed part using a pushing assembly. This eliminates the need for operators to manually clamp the workpiece, improving the ease of clamping operations and thus increasing production efficiency. Furthermore, the clamping members are detachably connected to the movable and fixed parts, allowing the clamping members to be machined with clamping grooves tailored to the workpiece shape and replaced with the appropriate clamping members as needed when using the valve clamp for workpieces with different structures. This enhances the versatility of the valve clamp, improves design efficiency, reduces manufacturing workload and material costs, and shortens the development cycle.

[0017] Furthermore, the jacking assembly simultaneously pushes the two movable parts on both sides toward the fixed part, so that when the operator adjusts the jacking assembly, it can drive the two sets of clamping parts on both sides to move closer together to clamp the workpiece, that is, clamp two workpieces at once, which makes the valve clamp more convenient to use and operate, and also makes the overall structure of the clamping assembly simpler and more compact.

Detailed Implementation

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0028] Please refer to the attached document. Figure 1-7This application provides a general-purpose valve clamp, including a bridge plate 1. Several clamping components are mounted on the surface of the bridge plate 1. Each clamping component includes a movable part 2, a pushing component, a fixed part 3, and clamping members 4. The movable part 2 is slidably connected to the bridge plate 1 via a sliding mechanism. Two symmetrical clamping members 4 are detachably disposed on the movable part 2 and the fixed part 3, respectively. A clamping groove 401 is formed on one side of the two clamping members 4 facing each other. The clamping groove 401 is configured to fit against the side wall of the workpiece 7. The pushing component is configured to push the movable part 2 to move and slide closer to the fixed part 3, thereby adjusting the clamping distance between the two clamping members 4 to clamp the workpiece 7. Each set of clamping components includes two fixed parts 3 on the left and right. The pushing component is disposed between the two fixed parts 3 and the movable part 2 is connected to both sides of the pushing component. The pushing component simultaneously pushes the two movable parts 2 on both sides to slide towards the fixed part 3.

[0029] In this embodiment, the push assembly pushes the movable part 2 towards the fixed part 3, thereby clamping the workpiece 7 between the two clamping members 4. This eliminates the need for the operator to hold the workpiece 7 manually, improving the ease of clamping operation and thus increasing production efficiency. Furthermore, the clamping members 4 are detachably connected to the movable part 2 and the fixed part 3. This allows the valve clamp to be used with workpieces 7 of different structures simply by machining the clamping groove 401 of the clamping member 4 according to the shape of the workpiece 7, and by replacing the corresponding clamping member 4 as needed. This improves the versatility of the valve clamp, enhances design efficiency, reduces manufacturing load and material costs, and shortens the development cycle. Additionally, the push assembly simultaneously pushes the two movable parts 2 on both sides towards the fixed part 3, allowing the operator to adjust the push assembly to bring the two sets of clamping members 4 together to clamp the workpiece 7, thus clamping two workpieces 7 at once. This makes the valve clamp operation more convenient and the overall structure of the clamping assembly simpler and more compact.

[0030] Preferably, the two adjacent clamping assemblies share a central fixing part 3, which makes the valve clamp structure simpler and more compact.

[0031] Among them, the bridge plate 1 has a relief opening 101 cut out in the part facing the workpiece 7, so that when the valve clamp is used on the workpiece 7 which is relatively high, the relief opening 101 can avoid the workpiece 7 to ensure the stability of the clamping effect.

[0032] The fixing part 3 is fixed to the bridge plate 1 by bolt connection, so that the clamping assembly is detachably connected to the bridge plate 1, which is convenient for processing and replacement.

[0033] Please refer to the attached document. Figure 2In some embodiments of this application, the clamping member 4 is detachably connected to the movable part 2 and the fixed part 3 by means of a threaded connection. This not only makes the connection strength between the clamping member 4, the movable part 2, and the fixed part 3 high, but also makes the installation and removal of the clamping member 4 more convenient.

[0034] The clamping member 4 has a connecting hole hollowed out in the middle along the left and right directions. The movable part 2 and the fixed part 3 are respectively provided with threaded holes. The bolt is inserted from the clamping groove 401 side of the clamping member 4 and screwed to the movable part 2 or the fixed part 3.

[0035] Please refer to the attached document. Figure 2 In some embodiments of this application, a first positioning mechanism is also provided between the clamping member 4, the movable part 2, and the fixed part 3. The positioning mechanism includes a first positioning protrusion 410 and a first positioning groove 310 that engage with each other. The first positioning protrusion 410 is disposed on the clamping member 4, the movable part 2, and the fixed part 3, and the first positioning groove 310 is formed by corresponding recesses.

[0036] In this embodiment, when installing the clamping member 4, the first positioning protrusion 410 is aligned with the first positioning groove 310 and inserted, so that the clamping member 4 and the movable part 2 or the fixed part 3 are relatively fixed in the front-to-back direction and the vertical direction, thereby facilitating the screwing in of bolts to fix the clamping member 4. As a result, the positioning operation during the installation of the clamping member 4 is relatively simple.

[0037] Preferably, the first positioning protrusion 410 and the first positioning groove 310 are square structures, so that after the first positioning protrusion 410 is engaged with the first positioning groove 310, the clamping member 4 cannot rotate around the movable part 2 or the fixed part 3, thereby improving the positioning accuracy. Of course, in other embodiments of this application, the cross-section of the first positioning protrusion 410 and the first positioning groove 310 can also be a triangular, elliptical, pentagonal, or other structures other than a perfect circle.

[0038] Please refer to the attached document. Figure 3-5 In some embodiments of this application, the push assembly includes a push part 5 and an adjusting member 6. The push part 5 has a connecting hole 510 hollowed out along the vertical direction. From top to bottom, the adjusting member 6 includes a screwing part 610, a connecting part 620, and a threaded part 630. The connecting part 620 is engaged with the push part 5 through the connecting hole 510. The diameters of the screwing part 610 and the threaded part 630 are larger than the connecting hole 510, so that the adjusting member 6 and the push part 5 are relatively fixed in the vertical direction. The threaded part 630 has an external thread and is threadedly connected to the bridge plate 1. The end face of the push part 5 near the movable part 2 and / or the end face of the movable part 2 near the push part 5 are inclined. When the screwing part 610 is screwed, the adjusting member 6 drives the push part 5 to slide up and down, thereby pushing the movable part 2 through the push part 5 and forcing the movable part 2 to slide left and right along the inclined surface.

[0039] In this embodiment, the adjusting member 6 is screwed to the bridge plate 1, allowing the operator to simply rotate the screwing part 610 to convert the rotation of the adjusting member 6 into the vertical movement of the pushing part 5. Furthermore, the inclined surface between the pushing part 5 and the movable part 2 further converts the vertical movement of the pushing part 5 into the horizontal movement of the movable part 2, thereby shortening the distance between the two clamping members 4 and clamping the workpiece 7. The transmission effect is stable and the adjustment operation is very simple. Moreover, after stopping the rotation of the screwing part 610, the adjusting member 6 will not rotate, allowing the pushing part 5 and the movable part 2 to be stably fixed in their current positions, thus ensuring a stable clamping effect of the valve clamp.

[0040] Please refer to the appendix. Figure 6 A mounting hole 102 is provided on the bridge plate 1 opposite the adjusting component 6. An internal threaded sleeve 130 is embedded in the mounting hole 102, and the threaded portion 630 is threadedly connected to the internal threaded sleeve 130. Furthermore, the internal threaded sleeve 130 has a stepped structure, including an annular support portion 131 extending outward from the bottom end, and the mounting hole 102 is also a corresponding stepped countersunk hole. After the internal threaded sleeve 130 is inserted into the mounting hole 102, a screw is screwed into the support portion 131, thereby screwing the internal threaded sleeve 130 and the bridge plate 1 together. This not only makes it convenient to install and remove the internal threaded sleeve 130 from the bridge plate 1, but also ensures a high connection strength between the two.

[0041] Preferably, the screwing part 610 is an internal hexagonal nut structure, which allows the operator to easily screw the relatively small screwing part 610 with the help of an internal hexagonal wrench.

[0042] Please refer to the attached document. Figure 3-5 In some embodiments of this application, the opposing end faces of the movable part 2 and the pushing part 5 are inclined in the same direction. This makes the movable part 2 and the pushing part 5 fit together more closely, resulting in a stronger connection. When the pushing part 5 pushes the movable part 2 in the vertical direction, the movable part 2 can slide more stably in the horizontal direction along the inclination direction of the two inclined surfaces, thereby making the transmission process between the movable part 2 and the pushing part 5 more stable.

[0043] Preferably, the inclination direction of the opposing end faces of the movable part 2 and the pushing part 5 is such that the height of the end faces gradually increases from the pushing part 5 towards the fixed part 3. This causes the movable part 2 to be compressed and move towards the fixed part 3 when the pushing part 5 moves downward. Furthermore, the pushing part 5 can be directly installed onto the bridge plate 1 from top to bottom without being blocked by the movable part 2. Of course, in other embodiments of this application, the inclination direction of the opposing end faces of the movable part 2 and the pushing part 5 can also be such that the height of the end faces gradually decreases from the pushing part 5 towards the fixed part 3.

[0044] Please refer to the attached document. Figure 5In some embodiments of this application, a second positioning mechanism is further provided between the opposing end faces of the movable part 2 and the pushing part 5. The second positioning mechanism includes a second positioning protrusion 520 and a second positioning groove 210 that are interlocked with each other. The second positioning protrusion 520 is disposed in one of the movable part 2 and the pushing part 5, and the second positioning groove 210 is disposed in the other of the movable part 2 and the pushing part 5. When the pushing part 5 pushes the movable part 2 to slide in the left-right direction, the second positioning protrusion 520 slides in the second positioning groove 210. This improves the connection strength between the movable part 2 and the pushing part 5, making the movable part 2 and the pushing part 5 relatively fixed in the front-back direction. The movable part 2 can only slide in the inclined direction, effectively preventing the movable part 2 from shifting during the sliding process, thereby improving the stability of the valve clamp.

[0045] Preferably, a second positioning groove 210 extending along the length direction is recessed on the side wall of the movable part 2 near the pushing part 5, and a second positioning protrusion 520 is correspondingly protruded on the side wall of the pushing part 5. Of course, in other embodiments of this application, the second positioning groove 210 may also be formed on the side wall of the pushing part 5, and the second positioning protrusion 520 may be correspondingly provided on the side wall of the movable part 2.

[0046] Please refer to the attached document. Figure 5 In some embodiments of this application, the connecting hole 510 is open on one side in the horizontal direction, allowing the connecting part 620 to be inserted into the connecting hole 510 through the opening. This makes the installation and disassembly of the adjusting member 6 and the pushing part 5 more convenient.

[0047] Preferably, the connecting hole 510 is provided with an opening on the left or right side, that is, on the side of the push part 5 near the movable part 2.

[0048] Please refer to the attached document. Figure 4-5 In some embodiments of this application, a plurality of vertical first limiting members 110 are connected to the bridge plate 1, and the front and rear ends of the pushing part 5 are stopped by the first limiting members 110, so that the pushing part 5 and the bridge plate 1 remain relatively fixed in the front and rear orientation.

[0049] In this embodiment, the push part 5 is stopped by the two first limiting members 110 at the front and rear, so that the push part 5 cannot rotate relative to the bridge plate 1. This prevents the push part 5 from being rotated by the adjusting member 6 when the adjusting member 6 rotates, thereby avoiding the push part 5 from deviating and further improving the stability of the valve clamp.

[0050] The front and rear side walls of the pushing part 5 are recessed to form vertical limiting grooves 501. The first limiting member 110 abuts against the limiting groove 501 and slides within the limiting groove 501 when the pushing part 5 moves up and down. This further enhances the connection strength between the first limiting member 110 and the pushing part 5, resulting in better stability. Furthermore, the bottom of the first limiting member 110 has external threads, and the first limiting member 110 is fixed to the bridge plate 1 by a threaded connection, making installation and disassembly convenient.

[0051] Please refer to the attached document. Figure 7 In some embodiments of this application, the bridge plate 1 is provided with a plurality of second limiting members 120, and the front and rear ends of each movable part 2 are attached to the second limiting member 120. The sliding mechanism includes a sliding part 220 and a sliding limiting groove 121. The sliding part 220 or the second limiting member 120 is provided with a sliding limiting groove 121 that runs through the left and right sides. The sliding part 220 is correspondingly disposed in the other of the sliding part 220 and the second limiting member 120. The sliding part 220 slides left and right along the sliding limiting groove 121, so that the movable part 2 can slide left and right relative to the bridge plate 1.

[0052] In this embodiment, the sliding part 220 and the sliding limiting groove 121, which are interlocked with each other, allow the movable part 2 to slide only left and right relative to the bridge plate 1, thereby improving the connection strength between the two and preventing the movement direction of the movable part 2 from deviating and affecting the clamping effect, resulting in better stability.

[0053] Preferably, the second limiting member 120 has an inverted L-shaped structure and is fixed to the bridge plate 1 by screws. The gap between its horizontal portion and the bridge plate 1 forms a sliding limiting groove 121. The bottom of the front and rear ends of the movable part 2 protrudes to form sliding portions 220, so that when installing the movable part 2, it is only necessary to place the movable part 2 on the bridge plate 1 first, and then screw the second limiting member 120 to the bridge plate 1 and press the sliding portion 220 into the sliding limiting groove 121. Of course, in other embodiments of this application, the sliding portion 220 can also be provided on the second limiting member 120, and the sliding limiting groove 121 can be provided on the movable part 2.
