Description

Technical Field

[0001] This utility model relates to the field of ball valve manufacturing, and in particular to a ball valve welding and testing device. Background Technology

[0002] Ball valve hot melt welding is a welding method used to connect ball valve components. It is mainly applied to ball valves made of plastic materials, especially thermoplastic ball valves such as polypropylene (PP) and polyethylene (PE). This welding process softens the material by heating to achieve the purpose of connection, thereby assembling the ball valve parts.

[0003] When welding ball valve components, the ball valve is usually fed by a vibrating feeder. The feeding assembly then places the ball valve component in the support seat on the support platform. The welding gun, under the action of the lifting mechanism, can then perform welding processing on the ball valve component.

[0004] Furthermore, to improve the quality of ball valve component production, after the ball valve component welding is completed, an inspection instrument is usually installed on the side of the supporting platform. This instrument checks the position and firmness of the welded ball valve components to determine whether the welding quality is up to standard. The inspection instrument also moves up and down via a lifting mechanism. Since the supporting platform stops rotating when the welding gun is welding the ball valve component, the inspection instrument also descends to inspect the quality of the ball valve component. However, using two independent lifting mechanisms to drive the welding gun and the inspection instrument up and down separately not only increases the equipment manufacturing cost but also causes the welding gun and the inspection instrument to move asynchronously, thus introducing certain defects.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides, for example Figure 1-3 The image shows a ball valve welding and testing device.

[0041] Example 1

[0042] The assembly includes a support platform 1, a drive disc 2, a support base 3, a welding gun 4, a testing instrument 5, and a lifting assembly 6. The drive disc 2 is rotatably mounted on top of the support platform 1, and a servo motor is installed at the bottom of the support platform 1. The servo motor drives the drive disc 2 to rotate a certain angle, thereby moving the ball valve component on the support base 3 to the bottom of the welding gun 4 and the testing instrument 5. This is existing technology and will not be described in detail here. The support base 3 is installed in a circular array on top of the drive disc 2 and is used to support the ball valve component. The welding gun 4 is located on top of the support platform 1 and is used to weld the ball valve component on the support base 3. In the welding process, the inspection instrument 5 is set on the top of the support platform 1. The inspection instrument 5 is used to inspect the ball valve parts on the support seat 3. The inspection instrument 5 is composed of pressure sensors, position sensors, etc. Thus, the detection probe of the inspection instrument 5 contacts the welded part of the ball valve part, and can perform quality inspection. This is existing technology and will not be described in detail here. The lifting assembly 6 is installed on the support platform 1. The lifting assembly 6 is used to drive the welding gun 4 and the inspection instrument 5 to move up and down. The lifting assembly 6 drives the welding gun 4 to make flexible contact with the ball valve part, which not only reduces the equipment manufacturing cost, but also reduces the damage caused by rigid extrusion between the welding gun 4 and the ball valve part.

[0043] Furthermore, the lifting assembly 6 includes an integrated frame 61, a first arm plate 62, a second arm plate 63, and a drive cylinder 64. The integrated frame 61 is mounted on the top of the support platform 1. The outer wall of the first arm plate 62 is slidably connected to the integrated frame 61, and one end of the first arm plate 62 is connected to the welding gun 4. The outer wall of the second arm plate 63 is slidably connected to the integrated frame 61, and one end of the second arm plate 63 is connected to the detector 5. The drive cylinder 64 is mounted on the top of the integrated frame 61, and the output end of the drive cylinder 64 is connected to the second arm plate 63. The second arm plate 63 is located on top of the first arm plate 62, thereby driving the cylinder. The cylinder 64 can drive the second arm plate 63 to move up and down. The lifting assembly 6 also includes a connecting assembly 65 and a limiting spring 66. The connecting assembly 65 is disposed between the second arm plate 63 and the first arm plate 62, and the limiting spring 66 is disposed between the second arm plate 63 and the first arm plate 62. The second arm plate 63 can drive the first arm plate 62 to descend through the connecting assembly 65 and the limiting spring 66. When the second arm plate 63 descends, the second arm plate 63 squeezes the first arm plate 62 to descend through the limiting spring 66, so that the welding gun 4 can flexibly contact the ball valve component, thereby allowing the welding gun 4 to perform heat fusion flexible welding on the welding joint of the ball valve component.

[0044] Specifically, the connecting assembly 65 includes a connecting rod 651, a limiting block 652, a limiting collar 653, and a positioning plate 654. The top of the connecting rod 651 is fixedly connected to the second arm plate 63, and the outer wall of the connecting rod 651 is slidably inserted into the first arm plate 62. The limiting block 652 is fixedly connected to the bottom of the connecting rod 651. When the driving cylinder 64 drives the second arm plate 63 to rise, the second arm plate 63 can drive the first arm plate 62 to rise through the connecting rod 651 and the limiting block 652, thus limiting the movement of the first arm plate 62. Block 652 is located at the bottom of the first arm plate 62, and the limiting collar 653 is fixedly sleeved on the bottom of the connecting rod 651. The limiting collar 653 is located at the top of the first arm plate 62, and the end of the positioning plate 654 is connected to the integrated frame 61. The positioning plate 654 is used to limit the first arm plate 62. Under the action of the positioning plate 654 and the limiting collar 653, when the second arm plate 63 drives the detector 5 to descend to the detection area, the first arm plate 62 drives the welding gun 4 to descend to the lowest welding position.

[0045] Example 2

[0046] Based on Embodiment 1, the integrated frame 61 includes a mounting bracket 611, a top cover 612, a guide rod 613, and a fixing collar 614. The bottom of the mounting bracket 611 is fixedly connected to the support platform 1. The top cover 612 is fixedly installed on the top of the mounting bracket 611 by internal bolts. The top of the guide rod 613 is fixedly connected to the top cover 612. The outer wall of the guide rod 613 is slidably inserted and sleeved with the first arm plate 62 and the second arm plate 63. The limiting spring 66 is slidably sleeved on the outside of the guide rod 613. The fixing collar 614 is fixedly connected to the bottom of the inner wall of the mounting bracket 611. By removing the top cover 612, the guide rod 613 can be removed, thereby allowing the first arm plate 62 and the second arm plate 63 to be disassembled and maintained. The bottom of the outer wall of the guide rod 613 is slidably sleeved with the fixing collar 614. The guide rod 613 can ensure the stability of the first arm plate 62, the second arm plate 63, and the limiting spring 66 during use.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
