Description

Technical Field

[0001] The present invention relates to a wire taking screw rod, specifically a wire taking screw rod docking head. Background Art

[0002] The wire taking screw rod is installed on the wire taking vehicle. When the wire taking screw rod needs to take a branch pipe, first remove the wire cake and let it fall on the wire taking screw rod, then the wire taking vehicle takes the wire cake to the wire dropping station. At this time, the wire taking screw rod on the wire taking vehicle is already vacant. Move the wire taking vehicle to the branch pipe feeding position to take the branch pipe, and then send it to the wire cake taking station, so as to wind the wire intuitively, and repeat the above actions;

[0003] However, when the wire taking screw rod takes the branch pipe, the front end of the conventional wire taking screw rod has a chamfer, and the docking head is rigid, which causes the wire taking screw rod to wear during long-term docking contact and the branch pipe to be stuck in the groove formed by the chamfer;

[0004] In summary, how to prevent the branch pipe from being stuck in the groove formed by the chamfer and reduce the wear of the end of the wire taking screw rod has become an urgent problem for the researchers of our company to solve. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: how to prevent the branch pipe from being stuck in the groove formed by the chamfer and reduce the wear of the end of the wire taking screw rod;

[0006] To solve the above problems, the present invention adopts the following solutions:

[0007] The present invention is a wire taking screw rod docking head, including: a connecting flange; an extension pipe, the bottom of which is connected to the connecting flange, and an opening groove is formed at the top extending towards the bottom; a docking shaft head, which is placed in the opening groove, and a compression spring is arranged between the docking shaft head and the bottom of the extension pipe; a travel groove, which is formed on the outer wall of the extension pipe; a travel block, which is fixed on the side wall of the docking shaft head and is adapted to move linearly along the travel groove;

[0008] In this solution, the connecting flange is used to connect the extension pipe and the end of the wire taking screw rod. The end of the docking shaft head abuts against the end of the branch pipe feeding place. Since the docking shaft head is pressed, the docking shaft head will move along the mouth groove towards the bottom of the extension pipe. In order to prevent the docking shaft head from flipping during the movement, this solution adopts the travel block to move along the travel groove, and the docking shaft head is always abutted against the end of the branch pipe feeding place through the compression spring. When the end of the branch pipe feeding place compresses the compression spring until it abuts against the end of the extension pipe, at this time, the branch pipe feeding place and the extension pipe of the wire taking screw rod will not cause the branch pipe to be stuck due to the groove. In addition, since the docking shaft head and the end of the branch pipe feeding place are elastically connected, the generation of wear of the docking shaft head is reduced.

[0009] To prevent the docking shaft head from detaching from the extension tube, the present invention is characterized in that a long circular hole is provided on the outer wall of the extension tube along its height direction; a limit pin is installed on the side wall of the docking shaft head and is movably placed in the long circular hole;

[0010] During the process of compressing the docking shaft head, the limit pin moves in the long circular hole, thereby preventing the docking shaft head from detaching from the extension tube.

[0011] To enable the fine movement of the screw rod docking head, so as to achieve self-floating positioning during docking, the present invention adopts an extension tube including a tube body, a chassis placed at the bottom of the tube body and fixedly connected to the tube body; a shoulder screw that passes through the chassis and fixedly connects its threaded part to the connecting flange; a spring that is sleeved on the shoulder screw and has its ends respectively abutted against the connecting flange and the chassis;

[0012] In this solution, due to the existence of the spring and the shoulder screw, the chassis can displace within a small range relative to the connecting flange, thereby enabling the fine movement of the screw rod docking head.

[0013] The beneficial effects of the present invention: The present invention is a screw rod docking head. The end of the elastic docking shaft head abuts against the end of the branch pipe feeding part, so that the end of the branch pipe feeding part and the extension tube will not be stuck due to the existence of the chamfer. In addition, since the docking shaft head and the end of the branch pipe feeding part are elastically connected, the generation of wear of the docking shaft head is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the drawings and embodiments.

[0015] Figure 1 is an exploded view of the present invention;

[0016] Figure 2 is a sectional view of the present invention;

[0017] In the figure: 1 - connecting flange, 2 - extension tube, 3 - opening groove, 4 - docking shaft head, 5 - compression spring, 6 - travel groove, 7 - travel block, 8 - long circular hole, 9 - chassis, 10 - shoulder screw, 11 - spring DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0019] Such as Figure 1-2As shown, the present invention is a screw rod joint, comprising: a connecting flange 1; an extension tube 2, the bottom of which is connected to the connecting flange 1, and the top of which extends to the bottom to open an open groove 3; a docking shaft head 4, which is placed in the open groove 3, and a compression spring 5 is arranged between the bottom of the extension tube 2; a travel groove 6, which is opened on the outer wall of the extension tube 2; a travel block 7, which is fixed to the side wall of the docking shaft head 4 and is suitable for linear motion along the travel groove 6;

[0020] In this solution, the connecting flange is used to connect the extension tube and the end of the screw rod, and the end of the docking shaft head is abutted against the end of the branch tube feeding place. Since the docking shaft head is under pressure, the docking shaft head will move along the mouth groove toward the bottom of the extension tube. In order to prevent the docking shaft head from flipping during the movement, this solution adopts a stroke block to move along the stroke groove, and the compression spring is used to ensure that the docking shaft head is always abutted against the end of the branch tube feeding place. When the end of the branch tube feeding place compresses the compression spring until it abuts against the end of the extension tube, at this time, the branch tube feeding place and the extension tube of the screw rod will not cause the branch tube to be stuck due to the groove. In addition, since the docking shaft head and the end of the branch tube feeding place are elastically connected, the wear of the docking shaft head is reduced.

[0021] like Figure 1 As shown, in order to prevent the butt joint shaft head from being separated from the extension tube, the present invention adopts an oblong hole 8 opened on the outer wall of the extension tube 2 along its height direction; a limit pin movably placed in the oblong hole 8 is installed on the side wall of the butt joint shaft head 4;

[0022] When the butt joint shaft head is compressed, the limit pin moves in the oblong hole, thereby preventing the butt joint shaft head from being separated from the extension tube.

[0023] like Figure 1-2 As shown, in order to realize the micro-movement of the screw rod to the joint, so as to realize self-floating positioning during docking, the present invention adopts an extension tube 2 including a tube body, a chassis 9 placed at the bottom of the tube body and fixedly connected to the tube body; a shoulder screw 10, which passes through the chassis 9 and has its threaded portion fixedly connected to the connecting flange 1; a spring 11, which is sleeved on the shoulder screw 10, and has its ends respectively abutted against the connecting flange 1 and the chassis 9;

[0024] In this solution, due to the presence of the spring shoulder screw, the chassis can undergo a small range of displacement relative to the connecting flange, thereby enabling micro-movement of the screw rod to the joint.

[0025] The present invention is a screw rod joint, in which the end of an elastic joint shaft head abuts against the end of a branch pipe feeding place, so that the end of the branch pipe feeding place and the extension pipe will not be stuck due to the existence of the chamfer, and in addition, since the joint shaft head and the end of the branch pipe feeding place are elastically connected, the wear of the joint shaft head is reduced.

[0026] Taking the above-described ideal embodiment of the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
