Description

Technical Field

[0001] This invention relates to the field of aero-engine production equipment technology, and more specifically, to a flexible sheep hair brush welding device. Background Technology

[0002] Adjustable stator blades (VSVs) in high-pressure compressors of aero-engines achieve the effects of changing compressor flow rate, increasing compressor operating margin, and improving compressor efficiency by altering the angle of the adjustable stator blades. The angle of the adjustable stator blades is adjusted via an adjustment mechanism. Generally, the adjustment mechanism consists of a rocker arm, a linkage ring, a connecting rod, a crank, a control lever, and a drive unit. The rocker arm is divided into rigid rocker arms and flexible rocker arms. Flexible rocker arms are widely used in mainstream aero-engines because they can significantly reduce the weight of the aero-engine.

[0003] The rocker arm body and rocker arm pin of a flexible rocker arm are often fixed by riveting or welding. However, these methods have the following drawbacks: when riveting the pin, it is difficult to guarantee the accuracy between the pin and the rocker arm body under impact loads; while welding easily causes thermal deformation of both the rocker arm pin and the rocker arm body, making it difficult to guarantee the welding effect. Therefore, how to effectively fix the rocker arm body and rocker arm pin and improve the manufacturing yield of flexible rocker arms has become an urgent technical problem to be solved in this field.

[0036] Figure 1 This is a schematic diagram of the flexible rocker arm 200 provided in this embodiment. Figure 2 This diagram shows the structure of the flexible rocker arm welding equipment 100 provided in this embodiment. Figure 3 A schematic diagram of the rocker arm positioning component 110 in the flexible rocker arm welding equipment 100 provided in this embodiment is shown. Please refer to the attached diagram. Figures 1-3 This embodiment provides a flexible rocker arm welding device 100, which is used to weld a flexible rocker arm 200. Specifically, as shown... Figure 1 As shown, the flexible rocker arm 200 includes a rocker arm body 210 and a rocker arm pin 220. The rocker arm body 210 has a large end 211 and a small end 212. Through holes are provided at the small end 212 and the large end 211 of the rocker arm body 210, respectively. These through holes are a first through hole 213 and a second through hole 214. The rocker arm pin 220 is inserted into the first through hole 213. Therefore, when welding the rocker arm body 210 and the rocker arm pin 220, the welding part 230 is the area around the rocker arm pin 220 at the first through hole 213.

[0037] The flexible rocker arm welding equipment 100 includes a rocker arm positioning component 110 and a rotary welding assembly. A pin positioning hole 113 is provided at the center of the rocker arm positioning component 110, for inserting a rocker arm pin 220 to position it. A positioning protrusion 114 is provided on one side of the pin positioning hole 113, which is inserted into a second through hole 214 on the rocker arm body 210, thereby positioning the rocker arm body 210 and ensuring the positioning accuracy between the rocker arm body 210 and the rocker arm pin 220. The rotary welding assembly includes a rotating component 120 and a welding structure 130 mounted on the rotating component 120. The rotating component 120 drives the welding structure 130 to rotate around the center of the rocker arm positioning component 110. Thus, while the rocker arm positioning component 110 remains fixed, the rocker arm pin 220 is welded around one revolution by the welding structure 130. During the welding process, the rocker arm body 210 and the rocker arm pin 220 are kept in a limited position by the rocker arm positioning component 110 and are not affected by welding heat deformation, thereby helping to improve the manufacturing qualification rate of the flexible rocker arm 200.

[0038] The flexible rocker arm welding equipment 100 provided in this embodiment will be further described below:

[0039] Please continue to refer to the reference. Figures 1-3 In this embodiment, the rocker arm positioning member 110 is generally disc-shaped, and the pin positioning hole 113 is located at the center of the rocker arm positioning member 110 and is coaxially arranged with the rocker arm positioning member 110. The positioning protrusion 114 is located on one side of the pin positioning hole 113. Further, a first boss 111 is provided at the center of the rocker arm positioning member 110, and the pin positioning hole 113 is provided on the first boss 111, which is cylindrical. A second boss 112 is provided radially along the rocker arm positioning member 110. The second boss 112 is strip-shaped, and the positioning protrusion 114 is provided on the second boss 112. During positioning, the small end 212 of the rocker arm body 210 is supported by the first boss 111, and the large end 211 of the rocker arm body 210 is supported by the second boss 112. The height of the second boss 112 is lower than that of the first boss 111, thereby ensuring that the rocker arm body 210 is in a horizontal state.

[0040] Figure 4 This is a cross-sectional structural diagram of the flexible rocker arm welding equipment 100 provided in this embodiment. Please refer to the diagram. Figures 1-4 Furthermore, in this embodiment, the flexible rocker arm welding equipment 100 also includes a clamping nut 117. The positioning protrusion 114 is provided with a threaded portion, and the clamping nut 117 is screwed into the threaded portion, thereby pressing the rocker arm body 210 against the second protrusion 112 of the rocker arm positioning member 110.

[0041] Furthermore, the flexible rocker arm welding equipment 100 also includes a clamping screw 116, the lower end of which is used to clamp the rocker arm pin 220.

[0042] Optionally, the rotating component 120 includes a rotating seat 121 and a rotating bracket 123. The rotating seat 121 is rotatably mounted on the rocker arm positioning component 110. The rotating bracket 123 includes a first arm 124, a connecting arm 126, and a second arm 125 connected in sequence. The free ends of the first arm 124 and the second arm 125 are mounted on the rotating seat 121. The connecting arm 126 is located directly above the positioning pin hole. The upper end of the clamping screw 116 is connected to the connecting arm 126, so that the clamping screw 116 is directly above the rocker arm pin 220, thereby applying downward pressure to the rocker arm pin 220 through the clamping screw 116.

[0043] Specifically, the first arm 124, the connecting arm 126, and the second arm 125 can be integrally bent to form a U-shaped structure with the opening facing downwards. The end of the first arm 124 away from the connecting arm 126 is the free end of the first arm 124. The free end of the first arm 124 is bent outwards to form a horizontally extending first connecting arm 126. The rotating base 121 is provided with an annular flange, and the first connecting arm 126 is locked and fixed to the annular flange by the first connecting bolt assembly 127. Similarly, the end of the second arm 125 away from the connecting arm 126 is the free end of the second arm 125. The free end of the second arm 125 is bent outwards to form a horizontally extending second connecting arm 126, and the second connecting arm 126 is locked and fixed to the annular flange by the second connecting bolt assembly 128. This achieves a fixed connection between the rotating base 121 and the rotating bracket 123. It is understood that in some other embodiments, other methods can be used to achieve a fixed connection between the rotating base 121 and the rotating bracket 123.

[0044] Optionally, one end of the welded structure 130 is fixedly mounted on the first support arm 124.

[0045] Figure 5 This is a schematic diagram of the connection structure between the welding structure 130 and the first support arm 124 in the flexible rocker arm welding equipment 100 provided in this embodiment. Figure 6 This diagram shows a partial cross-sectional view of the flexible rocker arm welding equipment 100 provided in this embodiment. Please refer to the attached diagram. Figures 1-6 In this embodiment, the welding structure 130 includes a welding component 131, a wire filling assembly 133, and a mounting assembly 137. The welding component 131 has a welding head extending to the center of the rocker arm positioning component 110. The welding head is used to weld the rocker arm pin 220 to the rocker arm body 210, and a wire fixing tube 132 is provided on the welding head. The wire filling assembly 133 is used to automatically feed the welding wire 146, which extends from the wire filling assembly 133 to the wire fixing tube 132 and is welded under the action of the welding head. The welding component 131 and the wire filling assembly 133 are mounted on the rotating component 120 via the mounting assembly 137.

[0046] Optionally, the wire feeding assembly 133 includes a wire feeding drive wheel 134, a wire feeding driven wheel 135, and a wire feeding motor 136. The wire feeding motor 136 is connected to the wire feeding drive wheel 134 to drive the wire feeding drive wheel 134 to rotate. A wire feeding hole is formed between the wire feeding drive wheel 134 and the wire feeding driven wheel 135 for the wire feeding wire 146 to pass through. Thus, when the wire feeding motor 136 drives the wire feeding drive wheel 134 to rotate, the rotational friction of the wire feeding drive wheel 134 drives the wire feeding wire 146 to be fed, and correspondingly, the wire feeding driven wheel 135 rotates accordingly.

[0047] Optionally, the mounting assembly 137 includes a fixing frame 138 and a welding head clamp 139. The fixing frame 138 is fixedly mounted on the rotating component 120, and a receiving space 143 is formed between the fixing frame 138 and the rotating component 120. A wire feeding drive wheel 134 and a wire feeding driven wheel 135 are rotatably mounted in the receiving space 143. A wire feeding motor 136 is located outside the receiving space 143, and its output end extends into the receiving space 143 to connect with the wire feeding drive wheel 134. The welding head clamp 139 includes an arc-shaped holding portion 141 and a first connecting portion 140 and a second connecting portion 142 located on both sides of the arc-shaped holding portion 141. The first connecting portion 140 and the second connecting portion 142 are clamped between the rotating component 120 and the fixing frame 138 to be fixedly connected to the rotating component 120. The weldment 131 is clamped and fixed between the arc-shaped holding portion 141 and the rotating component 120, thereby achieving the fixation of the weldment 131.

[0048] Specifically, the fixing frame 138 has a recessed space with an opening at one end, the opening of which faces the first connecting arm 126, and the opening is blocked by the first connecting arm 126, thereby forming a receiving space 143. The first connecting part 140 and the second connecting part 142 are respectively clamped between the fixing frame 138 and the first connecting arm 126 on both sides of the opening.

[0049] Furthermore, the mounting assembly 137 also includes a first locking screw 144 and a second locking screw 145. The first locking screw 144 passes through the rotating component 120 and the first connecting portion 140 and is screwed onto the fixing bracket 138. The second locking screw 145 passes through the rotating component 120 and the second connecting portion 142 and is screwed onto the fixing bracket 138, thereby fixing the fixing bracket 138 and the welding head clamp 139 onto the rotating component 120.

[0050] Specifically, the fixing bracket 138 is provided with a first threaded hole and a second threaded hole on at least two sides of the opening. The first locking screw 144 passes through the first connecting arm 126 and the first connecting part 140 and is screwed into the first threaded hole. The second locking screw 145 passes through the first connecting arm 126 and the second connecting part 142 and is screwed into the second threaded hole.

[0051] Please continue to refer to the reference. Figures 1-6 In this embodiment, the flexible rocker arm welding equipment 100 further includes a drive motor 151, a motor bracket 152, and a transmission gear. The drive motor 151 is mounted on the motor bracket 152. The transmission gear includes a rotating drive wheel 153 and a rotating driven wheel 155 that mesh with each other. The rotating drive wheel 153 is mounted on the output shaft of the drive motor 151, and the rotating driven wheel 155 is mounted on the rotating component 120 so as to drive the rotating component 120 to rotate through the drive motor 151.

[0052] Specifically, the drive motor 151 is fixedly mounted on the motor bracket 152, and the output shaft of the drive motor 151 is rotatably supported on the motor bracket 152 via the first bearing 154. The rotating drive wheel 153 is mounted on the output shaft of the drive motor 151, and when the output shaft of the drive motor 151 rotates, the rotating drive wheel 153 rotates synchronously. The rotating driven wheel 155 meshes with the rotating drive wheel 153, and the rotating driven wheel 155 is fixedly connected to the rotating seat 121, so that the rotating drive wheel 153 drives the rotating driven wheel 155 to rotate, and drives the rotating seat 121 to rotate synchronously.

[0053] Furthermore, the rotating component 120 has a mounting hole 122 in the middle, and a mounting shaft 115 is provided on the lower side of the rocker arm positioning component 110. The mounting base is inserted into the mounting hole 122, and the end of the mounting shaft 115 is fixedly mounted on the motor bracket 152. The driven wheel 155 is rotatably supported on the mounting shaft 115 by a bearing, which is the second bearing 156.

[0054] Specifically, a mounting hole 122 is provided at the center of the rotating base 121. The mounting hole 122 is coaxially arranged with the rotating base 121; in other words, the axis of rotation of the rotating base 121 is the axis of the mounting hole 122. The lower end of the mounting shaft 115 extends out of the mounting hole 122, meaning the lower end of the mounting shaft 115 is located on the lower side of the rotating base 121, and the mounting shaft 115 is fixedly connected to the motor bracket 152, thus achieving the fixed installation of the rocker arm positioning component 110. The driven wheel 155 rotates and supports the portion of the mounting shaft 115 located between the motor bracket 152 and the rotating base 121 via the second bearing 156. Correspondingly, the driven wheel 155 is located below the rotating base, and the driven wheel 155 is fixedly connected to the lower part of the rotating base 121 by bolts.

[0055] The flexible rocker arm welding device 100 provided in the embodiments of the present invention, in use, first installs the rocker arm body 210 and the rocker arm pin 220 onto the rocker arm positioning component 110, and presses the rocker arm body 210 and the rocker arm pin 220 onto the rocker arm positioning component 110 by clamping nut 117 and clamping screw 116, so that the rocker arm positioning component 110 ensures the positional accuracy between the rocker arm body 210 and the rocker arm pin 220. Then, the drive motor 151 is started, which drives the rotating drive wheel 153 to rotate. Correspondingly, the rotating driven wheel 155 and the rotating seat fixedly connected to the rotating driven wheel 155 rotate synchronously, thereby causing the rotating bracket 123 and the welding structure 130 to rotate relative to the rocker arm positioning component 110. During the rotation, the rocker arm pin 220 is welded one revolution by the welding structure 130. The flexible rocker arm welding equipment 100 enables automated, high-precision welding of the flexible rocker arm 200. During the welding process, the rocker arm body 210 and the rocker arm pin 220 are precisely clamped and limited, unaffected by welding heat deformation, further improving the yield rate of the flexible rocker arm 200. The automated welding equipment increases the production efficiency of the flexible rocker arm 200, reduces the labor intensity of workers, and further reduces production costs.

[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
