Description

Technical Field

[0001] The present invention relates to the technical field of valve body assembly, in particular to a valve body assembly tool. Background Art

[0002] The valve body is a control component in fluid conveying systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. There are many types of valve bodies and a wide range of applications. During the valve body production process, different equipment is required to process the valve body to meet different requirements. This process requires the use of dedicated positioning tooling, which is used to position and clamp the valve body to facilitate processing.

[0003] The current valve body assembly tooling has certain shortcomings when used:

[0004] 1. When the existing valve body assembly tool is in use, the jaws on the tool are used to clamp the valve body in the same way, that is, clamping the outside or inside of the valve body. When assembling the valve body in different positions, the traditional tool is relatively limited, which will cause obstacles to the assembly position and affect the user experience of the tool.

[0005] 2. At the same time, the specifications and shapes of valve bodies are not the same. Therefore, when clamping valve bodies of different specifications, different sizes of tooling are needed to clamp and fix the tooling of different specifications, which is very inconvenient, limiting the scope of application of the tooling and making it less applicable.

[0006] 3. When assembling the valve body, if the bottom or position is inconvenient for the operator to operate, the valve body needs to be removed from the tooling and turned over to face the inconvenient position, and then the valve body needs to be reassembled on the tooling, which increases the assembly time and operation steps, and reduces the assembly efficiency.

[0020] 2. The present invention can drive the two groups of internal threaded sleeves to move through the action of the threads by rotating the bidirectional threaded rod, so that the spacing between the two groups of internal threaded sleeves can be flexibly adjusted, and the spacing between the arc-shaped clamping plates on the left and right sides can be changed accordingly. Valve bodies of different lengths can be assembled, thereby improving the applicability of valve body assembly and avoiding the inability to assemble the valve body due to the low applicability of tooling.

[0021] 3. The present invention is provided with a rotatable connecting mechanism, so that the connecting mechanism can drive the clamping mechanism to rotate as a whole, and the valve body is fixed between multiple sets of arc-shaped clamping plates.

The outer side of the first rotating ring 303 is evenly provided with three groups of arc-shaped through grooves 307. The two groups of first rotating rings 303 are evenly hinged with a hinged rod 305 on one side close to each other. The bottom of one side of the three groups of hinged rods 305 is hinged with a clamping rod 304. The bottom of the clamping rod 304 is provided with an arc-shaped clamping plate 306, which can clamp the valve body in different positions and in different ways to ensure different requirements of the valve body during assembly.

[0035] As a preferred solution of this embodiment: the arc-shaped clamping plate 306 is arc-shaped, and anti-slip pads are provided on one side of the top of the arc-shaped clamping plate 306 and the bottom of the arc-shaped clamping plate 306 to increase the friction between the valve body and improve the stability of the valve body when it is fixed.

[0037] As a preferred solution of this embodiment: the top of the clamping rod 304 passes through the interior of the second rotating ring 901, and the clamping rod 304 slides inside the arc-shaped through groove 307, so that the first rotating ring 303 will not be hindered by the clamping rod 304 when rotating.

[0038] As a preferred solution of this embodiment: a mounting seat is provided at the middle position of the top of the tooling base 1, and the bidirectional threaded rod 6 is connected to the mounting seat through a bearing. Both sides of the bidirectional threaded rod 6 extend to the interior of the internal threaded sleeve 7 and are connected to each other through threads, so that the two groups of internal threaded sleeves 7 can move in different directions at the same time.

[0039] As a preferred solution of this embodiment: an annular connecting frame is provided on one side of the pull rod 204, and a placement rack is provided at the middle position of the two ends of the top of the tooling base 1, so that the valve body can be placed still on the tooling while being clamped.

[0040] As a preferred solution of this embodiment, the internal thread of the first rotating ring 303 is connected with a fixing bolt, and the bottom of the fixing bolt contacts the second rotating ring 901 , which can fix the first rotating ring 303 and the second rotating ring 901 .

[0041] Example 1, as Figure 6-7 As shown, after the three groups of arc clamping plates 306 clamp and fix the outer side of the valve body, it is necessary to assemble the relevant positions on the outer side of the valve body. At this time, the arc clamping plates 306 need to be moved out from the outer side of the valve body. The arc clamping plates 306 are driven away from the outer side of the valve body by rotating the first rotating ring 303 in the opposite direction. Then, the two-way threaded rod 6 is rotated to drive the two groups of mounting plates 8 away from each other through the two groups of internal threaded sleeves 7, and finally the arc clamping plates 306 are driven to move to both sides of the valve body. At this time, the arc clamping plates 306 are driven to close to each other by rotating the first rotating ring 303. When the three valve bodies are completely moved to the interior of the valve body, the first rotating ring 303 is rotated again to move the arcuate splints 306 away from each other, so that the top of the arcuate splints 306 contacts and squeezes the inner side of the valve body, and the valve body is fixed by squeezing the arcuate splints 306. At this time, the components on the outside of the valve body can be assembled, which improves the applicability of the valve body during assembly.

[0042] Example 2, as Figure 2-7As shown, when assembling other positions of the valve body, the valve body needs to be turned over for the convenience of the operator so that the assembly position of the valve body is displayed in front of the operator, and the two sets of pull rods 204 are pulled to drive the fixed rack 207 and the second annular rack 903 to move away from each other, releasing the mutual fixation between the fixed ring 201 and the second rotating ring 901. At this time, the servo motor 202 is turned on to work, driving the driving gear 203 to rotate, and the driving gear 203 drives the first annular rack 902 meshing with it to rotate, thereby driving the second rotating ring 901 to rotate as a whole, and the second rotating ring 901 is rotated through the annular groove 904. The outer side of the annular slider 208 slides steadily, and the second rotating ring 901 drives the clamping mechanism 3 to rotate as a whole. Since the valve body is fixed between the three sets of arc-shaped clamping plates 306, the valve body rotates synchronously with the second rotating ring 901, so that the position where the valve body needs to be assembled is displayed in front of the operator, which is convenient for the operator to assemble and improves the functionality of the assembly tool. After the adjustment is completed, the pull rod 204 is released. Under the elastic force of the spring 206, the fixed rack 207 is reset and meshed with the second annular rack 903, completing the re-fixation of the fixed ring 201 and the second rotating ring 901, thereby preventing the valve body from rotating during assembly.

[0043] Working principle: First, place the valve body between the two sets of connecting mechanisms 9, adjust the distance between the two sets of mounting plates 8 according to the actual length of the valve body, rotate the two-way threaded rod 6, and drive the two sets of internal threaded sleeves 7 to move outside the two-way threaded rod 6 under the action of the thread, and the internal threaded sleeve 7 drives the mounting plate 8 as a whole to move closer to the valve body, thereby driving the three sets of arc-shaped splints 306 to move toward the outside of the valve body. When the three sets of arc-shaped splints 306 move around the valve body, the fixing bolts are rotated to release the first rotating ring 303, and then the first rotating ring 303 is rotated to make the supporting slide rod 302 move inside the arc-shaped groove 301. The first rotating ring 303 is rotated to rotate the supporting slide rod 302 to move inside the arc-shaped groove 301. The movement of the moving ring 303 pushes the three sets of hinged rods 305 to move, and the hinged rods 305 push the corresponding clamping rods 304 to move toward the center of the second rotating ring 901, so that the three sets of arc-shaped clamping plates 306 are close to the outside of the valve body, so that the three sets of arc-shaped clamping plates 306 firmly clamp the valve body. At this time, the fixing bolts are rotated so that the bottom of the fixing bolts are in tight contact with the second rotating ring 901, fixing the first rotating ring 303 to prevent the first rotating ring 303 from reversing and causing the three sets of arc-shaped clamping plates 306 to loosen, thereby avoiding affecting the assembly accuracy during subsequent assembly. At this time, the flange of the valve body can be assembled and other operations such as assembly can be performed.

[0044] When assembling other positions of the valve body, the valve body needs to be flipped over for the convenience of the operator so that the assembly position of the valve body is displayed in front of the operator. At this time, the servo motor 202 is turned on to work, driving the drive gear 203 to rotate, and the drive gear 203 drives the first annular rack 902 meshing with it to rotate, thereby driving the second rotating ring 901 to rotate as a whole. The second rotating ring 901 slides stably on the outside of the annular slider 208 through the annular groove 904, and the second rotating ring 901 drives the clamping mechanism 3 to rotate as a whole. Since the valve body is fixed between the three groups of arc-shaped clamping plates 306, the valve body rotates synchronously with the second rotating ring 901, so that the position where the valve body needs to be assembled is displayed in front of the operator, which is convenient for the operator to assemble and improves the functionality of the assembly tooling.

[0045] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
