Description

Technical Field

[0001] This utility model relates to the technical field of valve body assembly, specifically to a device for assembling valve body components. Background Technology

[0002] As a key component of fluid control systems, the assembly quality of the valve body assembly directly affects the system's sealing performance, reliability, and service life. During the assembly process, the valve cover, valve seat, or other components are typically fastened to the valve body using multiple bolts to form a pressure-bearing, sealed cavity. This process, while seemingly simple, actually demands stringent requirements in terms of precision, force, and sequence. Even slight deviations in any step can trigger a chain reaction, affecting the overall operational efficiency of the fluid system. To achieve precise assembly of the valve body assembly, a device similar to the valve body assembly assembly itself is needed to assist in the assembly process.

[0003] The existing technology has the following shortcomings: the bolt tightening process of current valve body assemblies mainly relies on manual operation. Operators need to use wrenches to pre-tighten and finally tighten each bolt individually. Manually tightening each bolt requires steps such as positioning, socketing, applying force, and repositioning, which is time-consuming. For valve body assemblies with multiple bolts, the overall tightening time accounts for a significant proportion of the entire assembly process, becoming a bottleneck restricting production efficiency. At the same time, repetitive manual tightening operations, especially when applying large torque or in inconvenient operating positions, are physically demanding for operators, easily leading to fatigue, affecting working conditions and product quality stability. Furthermore, manual operation makes it difficult to accurately control the final tightening torque of each bolt. Insufficient torque may lead to sealing failure and loosening of connections; excessive torque may cause bolt stretching, stripping, or even damage to the valve body threads. Utility Model Content

[0015] 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.

[0016] This utility model provides a technical solution: such as Figure 1 As shown in this embodiment, a device for assembling a valve body assembly includes a placement plate 1 for placing and fixing the valve body assembly. The surface of the placement plate 1 has multiple sets of annular grooves 2 for limiting the mounting bracket 6 and ensuring the stable rotation of the mounting bracket 6. An assembly component is provided above the placement plate 1 for tightening the bolts of the valve body assembly.

[0017] like Figure 2 and Figure 3 As shown, the assembly includes a fixing frame 3, on which a placement plate 1 is bolted for mounting and fixing a first motor 4. The first motor 4 is mounted on the top of the fixing frame 3 to drive a connecting plate 5 to rotate. The output end of the first motor 4 is mounted on the connecting plate 5. Mounting frames 6 are symmetrically mounted on both ends of the bottom of the connecting plate 5 via bolts. A limit rod 7 is mounted on the inner wall of the mounting frame 6 to control the first slider 8 and ensure its horizontal movement. The first slider 8 is slidably mounted on the outside of the limit rod 7. A fixing plate 9 is mounted on the top of the first slider 8. The fixed frame 3 has a U-shaped cross-section. The first slider 8 is slidably disposed with the mounting frame 6, and the mounting frame 6 is slidably disposed with the annular groove 2. The user can adjust the position of the limiting seat 18 and the limiting sleeve 22 by adjusting the front and rear position of the first slider 8, so as to ensure that the limiting seat 18 and the limiting sleeve 22 are located above and below the installation position. After tightening one set of bolts, the user starts the first motor 4. The first motor 4 drives the connecting plate 5 to rotate. The rotation of the connecting plate 5 drives the two sets of mounting frames 6 to rotate, so that the position of the two sets of mounting frames 6 can be adjusted, thereby completing the subsequent tightening of the remaining sets of bolts.

[0018] like Figure 2 and Figure 3 As shown, a motor frame 10 is mounted on the top of the fixing plate 9 for mounting and fixing the second motor 11, and also for limiting the movement of the lead screw nut 13 to ensure its vertical movement. The second motor 11 is mounted on the inner wall of the motor frame 10 to drive the transmission lead screw 12 to rotate. The output end of the second motor 11 is mounted on the transmission lead screw 12 to limit the movement of the second slider 14, ensuring its vertical movement. A lead screw nut 13 is sleeved on the outside of the transmission lead screw 12. A second slider 14 is slidably sleeved on the outside of the transmission lead screw 12 to adjust the height of the limiting seat 18. A return spring 15 is sleeved on the outside of the transmission lead screw 12 to ensure the stability of the limiting seat 18. Two sets of limiting discs 16 are sleeved on the outside of the transmission lead screw 12 to limit the movement range of the lead screw nut 13, thereby controlling the tightness of the nut. The motor frame 10 has a transverse L-shaped cross-section. The lead screw nut 13 is slidably mounted on the motor frame 10. The return spring 15 is located between the second slider 14 and the fixed plate 9. The two sets of limiting plates 16 are located above and below the lead screw nut 13, respectively. The limiting plates 16 and the transmission lead screw 12 are screwed together. The user puts the bolt into the limiting seat 18 and then presses down on the extension plate 17, causing the return spring 15 to compress. Then, the bolt is inserted into the hole to be fixed. Under the return force of the return spring 15, the bolt can be limited and fixed in the hole. When tightening the bolt and nut, the second motor 11 drives the transmission lead screw 12 to rotate clockwise. The rotation of the transmission lead screw 12 causes the lead screw nut 13 to move down. The movement of the lead screw nut 13 causes the limiting plate 19 to move. The movement of the limiting plate 19 causes the limiting sleeve 22 to move, which helps to complete the tightening of the bolt and nut. The user can adjust the position of the limiting plate 16 by rotating it, thereby adjusting the tightness of the nut.

[0019] like Figure 3 and Figure 4As shown, an extension plate 17 is bolted to the side wall of the second slider 14. A limiting seat 18 is installed at the top end of the extension plate 17. The limiting seat 18 and the extension plate 17 are detachable and used to limit the placement of the bolt. A limiting plate 19 is bolted to the side wall of the screw nut 13. The limiting plate 19 has multiple sets of arc-shaped grooves 20 on its surface for limiting the ratchet wrench 21 and ensuring its stable rotation. A ratchet wrench 21 is positioned above the limiting plate 19 for tightening the nut. A limiting sleeve 22 is installed at the end of the ratchet wrench 21. The limiting sleeve 22 and the ratchet wrench 21 are detachable and used to limit the placement of the nut. A third motor 23 is bolted to the bottom of the limiting plate 19 to drive the first connecting rod 24 to rotate. The output end of the third motor 23 is installed with the first connecting rod 24. A second connecting rod 25 is rotatably installed at the end of the first connecting rod 24 for rotating the first connecting rod 24. The transmission is performed by correspondingly setting the limiting seat 18 and the limiting sleeve 22. The arc groove 20 has a T-shaped cross-section. The ratchet wrench 21 is slidably set with the arc groove 20. The end of the second connecting rod 25 is rotatably connected to the ratchet wrench 21. With the limiting seat 18 and the limiting sleeve 22 being detachable, the user can replace the limiting seat 18 and the limiting sleeve 22 according to the size of the bolt and nut. After inserting the bolt into the mounting hole, the user puts the nut into the limiting sleeve 22 and puts it on the outside of the bolt. The third motor 23 drives the first connecting rod 24 to rotate. The rotation of the first connecting rod 24 causes the second connecting rod 25 to move back and forth. The movement of the second connecting rod 25 drives the ratchet wrench 21 to swing back and forth. When the ratchet wrench 21 swings clockwise, it can tighten the nut. When it swings counterclockwise, it returns to its original position and does not tighten. This completes the tightening of the bolt and nut, accurately controls the final tightening torque of each bolt, ensures the stability of product quality, and improves the efficiency of valve body assembly.
