Description

Technical Field

[0001] This application relates to the field of spinning equipment technology, specifically to a spinning head installation fixture for automatically tightening screws on the spinning head. Background Technology

[0002] The spinning head is a key component in spinning equipment, its function being to extrude the spinning melt or solution through the spinneret orifice to form filaments. In the chemical fiber production process, the spinning head needs to be cleaned, replaced, or maintained regularly; therefore, the disassembly and installation of the spinning head are routine procedures in the daily operation and maintenance of the production line.

[0003] Currently, the installation of spinning heads typically involves securing them to the spinning assembly or base using multiple screws. Traditional installation methods rely heavily on manual operation. Operators must first place the spinning head in the designated position, then manually insert multiple screws one by one into their corresponding screw holes, and finally tighten each screw sequentially using a tool. This is not only time-consuming and labor-intensive, but also prone to uneven tightening torque and screw stripping, especially in high-precision spinning head installations, leading to defects such as spindle head damage or air leakage. While some automated screw-tightening machines exist, these machines usually require complex fixture designs and adjustments for different products, lacking versatility and flexibility, and failing to meet the specific needs of spinning head installation. Utility Model Content

[0004] The purpose of this utility model is to provide a spinning head installation fixture for automatic screw tightening of spinning heads. Through a structured design, it enables precise and stable positioning and pre-assembly of batches of spinning heads and flange assemblies with pre-set threaded holes, providing a reliable physical basis for the fully automatic, high-precision, and high-efficiency tightening of the automatic screw tightening device for spinning heads, and improving the installation efficiency of spinning heads.

[0005] This application is achieved through the following technical solution, specifically:

[0006] A spinning head mounting fixture for automatically tightening screws on a spinning head includes: a base and at least one mounting seat connected to the end face of the base; the upper part of the base has a first groove for placing the spinning head, the bottom of the mounting seat has an opening communicating with the first groove, a set of positioning posts are symmetrically arranged on both sides of the opening, the inner wall of the positioning posts has a second groove matching the shape of a flange assembly, the flange assembly is used to connect the spinning head, and the flange assembly has a threaded hole for fixing and placing screws.

[0007] In this design, a first groove on the base provides a stable and accurately positioned platform for the spinning head. A positioning post on the mounting base and a second groove whose inner wall matches the shape of the flange assembly precisely guide and fix the position and orientation of the flange assembly, eliminating manual alignment errors and laying a precise alignment foundation for the tightening operation of the automatic spinning head screw-tightening device. This design provides a spinning head mounting fixture for automatic spinning head screw-tightening, enabling precise and stable positioning and pre-assembly of batches of spinning heads and flange assemblies with pre-set threaded holes. This provides a reliable physical basis for the fully automatic, high-precision, and high-efficiency tightening of the automatic spinning head screw-tightening device, improving the spinning head installation efficiency.

[0008] As an improvement to the mounting base in this application, the diameter of the opening is larger than the diameter of the first groove, and forms a stepped hole with the first groove, with the connection between the spinning head and the flange assembly placed in the stepped hole.

[0009] As an improvement to the flange assembly in this application, the flange assembly includes a first flange connected to the bottom of the spinning head and a second flange connected at one end to the pipe joint.

[0010] Furthermore, both the first flange and the second flange are diamond-shaped flanges with rounded chamfers at the four corners. The threaded holes are symmetrically arranged at two of the corners, and the corners where the threaded holes are located match the shape of the second groove.

[0011] As an improvement to the base in this application, the base is provided with handles at both ends.

[0012] As an improvement to the present application, the spinning head mounting fixture further includes a base disposed on the lower end face of the base.

[0013] Furthermore, the base includes a first base plate, a second base plate, and a support column connecting the first base plate and the second base plate.

[0014] Furthermore, a plurality of limiting blocks are provided on the upper surface of the first base plate, and the limiting blocks are distributed around the base.

[0015] The beneficial effects of this application are as follows:

[0016] The solution proposed in this application provides a stable and accurately positioned platform for the spinning head through a first groove on the base. Furthermore, the positioning post on the mounting base and its inner wall, which matches the shape of the flange assembly, precisely guide and fix the position and orientation of the flange assembly, eliminating manual alignment errors and laying a precise alignment foundation for the tightening operation of the automatic spinning head screw-tightening device. This solution provides a spinning head mounting fixture for automatic spinning head screw-tightening, enabling precise and stable positioning and pre-assembly of batches of spinning heads and flange assemblies with pre-set threaded holes. This provides a reliable physical basis for the fully automatic, high-precision, and high-efficiency tightening of the automatic spinning head screw-tightening device, improving the spinning head installation efficiency.

[0022] The following will be combined with the appendix Figures 1-2 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] In view of the problems existing in the background technology or products, Figure 1 A schematic diagram of a spinning head mounting fixture for automatically tightening screws on a spinning head, according to an embodiment of this application, is shown. Figure 1 As shown, this application embodiment provides a spinning head mounting fixture for automatically tightening screws on a spinning head, including: a base 1 and at least one mounting seat 2 connected to the end face of the base 1;

[0024] The base 1 has a first groove 11 for placing the spinning head 3 on its upper part. The mounting base 2 has an opening 21 at its bottom that communicates with the first groove 11. A set of positioning posts 22 are symmetrically arranged on both sides of the opening 21. The inner wall of the positioning post 22 has a second groove 23 that matches the shape of the flange assembly 4. The flange assembly 4 is used to connect the spinning head 3, and the flange assembly 4 has a threaded hole for fixing and placing screws.

[0025] Specifically, the base 1 is a strip-shaped base with at least one first groove 11 on its upper part. The number of first grooves 11 can be set according to actual needs, and this application does not limit this. The position and number of the first grooves 11 correspond to the mounting base 2. An opening 21 is opened at the bottom of the mounting base 2. The position of the opening 21 is spatially connected to the first groove 11 on the base 1, ensuring that when the spinning head 3 is placed in the first groove 11, the part that needs to be connected to the flange assembly 4 can be exposed or docked through the opening 21. Preferably, the diameter of the opening 21 is larger than the diameter of the first groove 11, and forms a stepped hole with the first groove 11. The connection part of the spinning head 3 and the flange assembly 4 is placed in the stepped hole. This allows the connection part to be well accommodated and supported, avoiding the connection operation of the spinning head 3 and the flange assembly 4 due to insufficient space.

[0026] To achieve precise positioning of flange assembly 4, a set of positioning posts 22 are symmetrically arranged on both sides of opening 21. These two positioning posts 22 extend vertically upward and have a second groove 23 on their inner wall that matches the outer contour of flange assembly 4. This achieves circumferential positioning and axial limiting of flange assembly 4, and also fixes the position of threaded hole on flange assembly 4. This provides a reliable alignment basis and stable workpiece state for the subsequent automatic screw tightening device of spinning head to accurately grasp the screw and align it with the threaded hole for fully automatic, high-precision, and high-efficiency tightening operation.

[0027] Continue reading Figure 1 In one implementation, the flange assembly 4 includes a first flange 41 connected to the bottom of the spinning head 3 and a second flange 42 connected at one end to the pipe joint 5.

[0028] Specifically, the spinning head 3 is connected to the pipe joint 5 through the first flange 41 and the second flange 42, and then connected to the equipment containing the spinning melt or solution (not shown in the figure) through the pipe joint 5.

[0029] Figure 2 This is a top view of a spinning head mounting fixture for automatically tightening screws on a spinning head, according to an embodiment of this application. See also... Figure 1 and 2 Preferably, both the first flange 41 and the second flange 42 are diamond-shaped flanges with rounded chamfers at the four corners. The threaded holes are symmetrically arranged at two of the corners, and the corners where the threaded holes are located match the shape of the second groove 23.

[0030] Specifically, when the flange assembly 4, consisting of the first flange 41 and the second flange 42, is placed into the mounting base 2, the bevel with the threaded hole will be accurately embedded into the second groove 23 on the positioning post 22. Through the shape constraint of the diamond flange, not only is the translation of the flange assembly 4 in the horizontal plane restricted, but its rotation angle is also limited, ensuring that the posture of the flange assembly 4 relative to the spinning head 3 is accurately fixed. In particular, the threaded hole is accurately positioned on the preset spatial coordinates, providing a reliable positioning basis for the subsequent automated screw tightening device to accurately align the screw with the threaded hole, place the screw, and perform the tightening operation, which greatly improves the assembly accuracy and automation efficiency.

[0031] Continue reading Figure 1 In one implementation, handles 12 are connected to both ends of the base 1. The purpose of the handles 12 is to provide operators with convenient gripping points, facilitating the movement and adjustment of the tooling's position and orientation.

[0032] Continue reading Figure 1 In one implementation, the spinning head mounting fixture further includes a base 6 disposed on the lower end face of the base 1.

[0033] The base 6 provides a more stable and reliable foundation support for the spinning head installation fixture, thereby reducing displacement or shaking that may be caused by vibration or external force during automated screw tightening, and further ensuring positioning accuracy.

[0034] Optionally, the base 6 includes a first base plate 61, a second base plate 62, and a support column 63 connecting the first base plate 61 and the second base plate 62. The base 1 is located on the upper surface of the first base plate 61. This structure not only provides stable support, but also allows adjustment of the working height of the entire tooling by adjusting the height of the support column 63, adapting to different automated production lines or operational needs.

[0035] Continue reading Figure 2Preferably, the upper surface of the first base plate 61 is provided with a plurality of limiting blocks 64, which are distributed around the base 1. When the base 1 is placed on the first base plate 61, the side edges of the base 1 abut against these protruding limiting blocks 64, thereby restricting the movement of the base 1 on the plane of the first base plate 61, thus achieving rapid, accurate and repeatable positioning of the base 1 relative to the base 6.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
