Description

Technical Field

[0001] The utility model belongs to the field of screw sleeve manufacturing, and in particular relates to an integrated device for plugging and sealing detection of a pre-buried screw sleeve. Background Art

[0002] During the manufacturing process of wind turbine blades, it is necessary to pre-embed the threaded sleeve at the root end so as to connect it to the tower or other components. When pre-embedded, in order to prevent the resin from entering the interior of the threaded sleeve and destroying the threaded connection, a plug needs to be provided at one end of the threaded sleeve located inside the wind turbine blade. The plug and the threaded sleeve body are sealed by sealant or a sealing ring to ensure that the resin does not penetrate into the interior of the threaded sleeve, thereby ensuring the connection stability and corrosion resistance of the threaded sleeve. Therefore, it is necessary to go through the process of pressing the plug and testing the sealing performance, connect the air tightness detection device, stabilize the air pressure, and observe whether the air pressure is significantly reduced to judge the sealing performance. In the prior art, pressing the plug and testing the sealing performance are performed separately on two devices, and are manually transferred between the two devices, resulting in low production efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an integrated device for pressing and sealing of a plug of an embedded screw sleeve, which solves the problem that pressing and sealing are performed on two devices respectively, resulting in low production efficiency.

[0022] Compared with the prior art, the utility model provides an integrated device for pressing and sealing detection of the plug, which places the screw sleeve 1.1 on one of the positioning seats 111 and fixes it with a corresponding clamping device 113, then places the plug on the top of the screw sleeve 1.1, and starts the corresponding linear reciprocating drive member 120 to press the plug, then the rotating table 110 rotates a certain angle to the bottom of the other linear reciprocating drive member 120, so that the other positioning seat 111 is in front, and repeats the above steps, at the same time, the other linear reciprocating drive member 120 presses the plug, and uses an airtightness detection system to perform a sealing detection on the screw sleeve 1.1 with the plug pressed on it. When the sealing is being tested, and the next screw sleeve 1.1 is also pressed on, the rotating table 110 rotates, the screw sleeve 1.1 with the sealing detected is removed, and a new screw sleeve 1.1 is installed, and the operation is repeated in this way, so that the pressing and sealing detection can be performed uninterruptedly, thereby eliminating the need for manual transfer and improving production efficiency.

[0023] In one embodiment, see Figure 3 The positioning seat 111 includes a support block 1111 and an annular guide 1112 arranged on the top of the support block 1111. The annular guide 1112 is used to guide the end face of the screw sleeve 1.1 to fit with the top surface of the support block 1111. Specifically. The support block 1111 is cylindrical in shape. The support block 1111 and the annular guide 1112 are fixed by screws for easy disassembly. The split structure is also easier to manufacture. The upper part of the inner wall of the annular guide 1112 is a conical surface, which guides the end of the screw sleeve 1.1, and the lower part is a cylindrical surface, which provides a certain radial support for the screw sleeve 1.1 to prevent the screw sleeve 1.1 from tipping over when it is placed.

[0024] Further, see Figure 3The top surface of the support block 1111 is provided with an annular groove 1114, and a sealing ring is arranged in the annular groove 1114 to improve the sealing between the support block 1111 and the screw sleeve 1.1.

[0025] In one embodiment, see also Figure 3 The through hole 1113 extends inward from the side wall of the positioning seat 111 and bends upward to extend through the positioning seat 111, so that the airtightness detection system can communicate with the internal threaded hole of the screw sleeve 1.1. Specifically, the through hole 1113 is opened in the support block 1111, one end of which is located on the side wall of the support block 1111, and the end is a threaded hole for screwing the connector 114, and the other end is located at the top center of the support block 1111. When the airtightness detection system is inflated, it can enter the inner hole of the screw sleeve 1.1 through the through hole 1113.

[0026] In one embodiment, the connector 114 is a quick connector, which improves the convenience of connecting and disconnecting the connector 114 from the air tightness detection system.

[0027] In one embodiment, the linear reciprocating drive member 120 is an oil cylinder, an electric cylinder or a pneumatic cylinder. Preferably, the linear reciprocating drive member 120 for pressing the plug is an oil cylinder, which can more easily complete the plug pressing with a higher pressure, and the linear reciprocating drive member 120 for limiting the plug is an electric cylinder, which can perform the action more quickly and has a smaller weight.

[0028] In one embodiment, a columnar pressing head is provided at the output end of the linear reciprocating driving member 120 for press-fitting the plug. During press-fitting, the columnar pressing head only contacts the plug, thereby reducing pressure dispersion and avoiding contact with other components to cause damage.

[0029] In one embodiment, a pressure cap is provided at the output end of the linear reciprocating drive member 120 for limiting the plug, and the pressure cap surrounds the end of the screw sleeve 1.1.

[0030] In one embodiment, the clamping device 113 is a pneumatic clamp.

[0031] In one embodiment, the integrated device for pressing and sealing detection of the plug of the embedded screw sleeve also includes a bracket 2 130 and a bracket 3 140, which are respectively used to install a linear reciprocating drive member 120 for pressing and installing the plug and a linear reciprocating drive member 120 for limiting the plug. The linear reciprocating drive members 120 with different functions are respectively arranged on the bracket 2 130 and the bracket 3 140, so that the structure of the bracket is more flexible, and the bracket can be designed to be more conducive to taking and placing the screw sleeve 1.1.
