DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1-4As shown, a servo drive expansion module grounding structure proposed in an embodiment of the utility model can effectively control the length of the grounding wire to avoid the influence of the wire being too long and affecting the ideal effect in the later stage, and can make the grounding structure convenient to be disassembled and assembled on the servo drive expansion module, so as to facilitate the maintenance and use of the servo drive expansion module in the later stage, including a grounding column 1, a sleeve 2, a limiter 3, a winding shell 4 and a grounding winding piece 5, a sleeve 2 is sleeved on the grounding column 1, a limiter 3 is matched and connected to the sleeve 2, the limiter 3 is matched and connected to the grounding column 1, a winding shell 4 is fixedly connected to the sleeve 2, a grounding winding piece 5 is matched and connected inside the winding shell 4, and the grounding winding piece 5 is matched with the grounding column 1 The interference setting, the grounding winding member 5 is rotated and connected with the sleeve 2, and is installed on the servo drive expansion module through the threaded connection of the threaded column 101. The grounding column 1 is made of conductive metal material and can be used for grounding. The sleeve 2 is sleeved on the grounding column 1, so that the interference cavity 201 and the top of the ball head 102 are in conflict with each other. Due to the limiting member 3 set on the sleeve 2, when the sleeve 2 and the grounding column 1 are sleeved, the ball head 102 will be in conflict with the elastic bar 301, causing it to deform, and then when the ball head 102 is in conflict with the conflict ball 302, the conflict ball 302 will slide and shrink in the connecting hole 203, so that the spring 303 is squeezed and contracted and maintains the rebound force. When the ball head 102 moves to align the limiting groove 103 with the conflict ball 302 When the spring 303 rebounds, the abutment ball 302 is engaged in the limiting groove 103, and the spring bar 301 abuts against the edge of the ball head 102 close to the threaded column 101, so that the sleeve 2 can be installed and used on the grounding column 1. The design of the limiting member 3 can make the sleeve 2 conveniently installed on the grounding column 1. Since the conductive shaft 504 rotatably connected in the plug hole 202 abuts against the top of the ball head 102, the conductive shaft 504 is made of conductive metal material, and the conductive shaft 504 is connected with the lead 501, so that the grounding conduction can be used. By pulling the pressing piece 502, the lead 501 is unwound and extended on the winding reel 503, and the winding reel 503 is rotatably connected to the inside of the winding shell 4, and the conductive shaft 504 is rotatably connected In the combined space of the rotating hole 401 and the plug hole 202, the conduction shaft 504 is always connected with the ball head 102 for rotation and resistance. When the conduction shaft 504 is rotated by the pulling force of the lead 501, the coil spring 505 will be wound and maintain the rebound force. The pressing piece 502 is connected to the grounding column 1. Therefore, after the pressing piece 502 is fixed, the lead 501 can be kept in a straight state under the rebound force of the coil spring 505, which can avoid the lead 501 from stretching too much, resulting in inconvenience in wire management in the later stage, and improve the management and use of the wire harness. The winding shell 4 is made of insulating plastic material. By covering the winding shell 4 on the outside of the winding drum 503, the insulation effect can be achieved. Through the coordinated design, when the servo drive expansion module is overhauled in the later stage,The sleeve 2 is conveniently pulled out from the grounding column 1, so that the grounding column 1 remains connected to the servo drive expansion module. The grounding structure other than the grounding column 1 is disassembled, which improves the convenience of disassembly and assembly of the grounding structure of this scheme.
