Description

Technical Field

[0001] This utility model relates to the field of weaving equipment technology, and in particular to a screw body structure, a spindle assembly, and a weaving machine. Background Technology

[0002] The spindle assembly in a braiding machine includes the spindle, compression spring, and screw body. The spindle refers to the main shaft or rod-like structure supporting the rotating parts; the compression spring provides pressure, damping, or reset; the screw body is threaded to the spindle, with both ends of the compression spring fixed between one end of the spindle and the screw body. The core function of the screw body is to adjust the pressure applied to the spindle by changing the compression of the compression spring through rotation. Forward rotation (tightening): increases the compression of the compression spring → increases the preload of the spindle → enhances yarn tension or mechanical stability; Reverse rotation (loosening): reduces the compression of the compression spring → reduces spindle pressure → alleviates yarn tension or vibration. The screw body allows for precise adjustment of spring pressure, directly affecting yarn quality (such as uniformity and breakage rate) and equipment lifespan.

[0003] See Figure 1 As shown, Figure 1 This is a schematic diagram of the screw body in the prior art; one end of the screw body 1' is threadedly connected to the spindle, and the two ends of the compression spring are respectively fixed between one end of the spindle and the screw body 1'. A pin hole 11 is provided in the middle of the screw body 1', and the pin hole 11 is arranged radially along the screw body 1'. When disassembling the screw body 1', a tool is inserted into the pin hole 11, with the tool perpendicular to the screw body 1'. By rotating the disassembly tool, the screw body 1' is disassembled.

[0004] When it is necessary to replace a new compression spring or a new screw body 1', or to add lubricating oil during maintenance, the screw body must be removed from the spindle.

[0005] The applicant has discovered that the prior art has at least the following technical problems: the two spindles on the braiding machine are very close together, making it difficult to insert the tools used for disassembly into the pin holes. Disassembly and maintenance can only be performed by rotating the other spindle to the outer ring after one of them has been replaced. Therefore, the disassembly of the screw body 1' in the prior art is very difficult and time-consuming. Utility Model Content

[0006] The purpose of this utility model is to provide a screw body structure, a spindle assembly, and a braiding machine to solve the technical problems of time-consuming, labor-intensive, and difficult operation when removing the screw body from the spindle in the prior art; the various technical effects of the preferred technical solutions provided by this utility model are described in detail below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The screw body structure provided by this utility model includes a screw body, on which a disassembly groove and an oil inlet channel are provided, wherein:

[0009] The disassembly groove is opened at one end of the screw body, and the other end of the screw body is used to install the compression spring. The groove opening is set in a direction away from the compression spring.

[0010] The oil inlet channel extends through both ends of the screw body. When the screw body is threadedly connected to the spindle, the oil outlet of the oil inlet channel is in communication with the inner cavity of the spindle.

[0011] Preferably, the oil inlet of the oil inlet channel is connected to the disassembly groove.

[0012] Preferably, the oil inlet channel, the disassembly groove, and the screw body are arranged coaxially.

[0016] The threaded section extends into the spindle and is threadedly connected to the spindle. The guide pin is fixed to the end of the threaded section opposite to the disassembly groove. The compression spring can be sleeved on the guide pin and abuts against the end face of the threaded section.

[0017] The oil inlet channel passes through the threaded section and the guide pin, and the oil outlet of the oil inlet channel is located at the end of the guide pin opposite to the threaded section.

[0018] Preferably, the end of the guide pin opposite to the disassembly groove is provided with a chamfered structure.

[0019] Preferably, the screw body is provided with an annular groove, which is used to engage and fix the pressure cap.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] See Figure 1 As shown, Figure 1 This is a schematic diagram of the screw body in the prior art. One end of the screw body 1' is threaded to the spindle, and the two ends of the compression spring are respectively fixed between one end of the spindle and the screw body 1'. A pin hole 11 is provided in the middle of the screw body 1', and the pin hole 11 is arranged radially along the screw body 1'. When disassembling the screw body 1', a tool is inserted into the pin hole 11, with the tool perpendicular to the screw body 1'. The screw body 1' is disassembled by rotating the disassembly tool. When it is necessary to replace a new compression spring or a new screw body 1', or to add lubricating oil for maintenance, the screw body needs to be removed from the spindle. The two spindles on the braiding machine are very close together, making it difficult to insert the disassembly tool into the pin hole. Only after replacing one of them can the other spindle be rotated to the outer ring for disassembly and maintenance. Therefore, the disassembly of the screw body 1' in the prior art is very difficult and time-consuming.

[0035] To address the aforementioned problems, this utility model provides a screw body structure, a spindle assembly, and a braiding machine, which facilitates the disassembly and assembly of the screw body and the lubrication and maintenance of the spindle assembly.

[0036] The following is combined with Figures 2-6 The technical solution provided by this utility model will be described in more detail.

[0037] Example 1:

[0038] See Figures 2-4As shown, the screw body structure of this embodiment includes a screw body 1, on which a disassembly groove 2 and an oil inlet channel 3 are provided. The disassembly groove 2 is opened at one end of the screw body 1, and the other end of the screw body 1 is used to install a compression spring 7. The groove opening of the disassembly groove 2 is arranged in a direction away from the compression spring 7. The oil inlet channel 3 passes through both ends of the screw body 1. When the screw body 1 and the spindle 8 are threadedly connected in place, the oil outlet 32 ​​of the oil inlet channel 3 is connected to the inner cavity of the spindle 8.

[0039] In this embodiment, the screw body structure has a disassembly groove 2 at the end of the screw body 1, which is located away from the direction of the compression spring 7. When the auxiliary disassembly tool is inserted into the disassembly groove 2, the auxiliary disassembly tool does not occupy the space between adjacent spindles 8. Therefore, the auxiliary disassembly tool will not interfere with the other spindles 8, which facilitates the disassembly and assembly of the screw body 1.

[0040] See Figure 2 As shown, when an auxiliary disassembly tool, such as a wrench, is inserted into the disassembly groove 2, the auxiliary disassembly tool extends along the axial direction of the screw body 1 without occupying the space between adjacent spindle assemblies, which facilitates the disassembly and assembly of the screw body 1.

[0041] See Figures 2-4 As shown, the oil inlet channel 3 runs through both ends of the screw body 1. The oil can be directly added into the oil inlet channel 3 from the end of the screw body 1 and enter the inner cavity of the spindle 8 for lubrication without disassembling the screw body 1, which facilitates the lubrication and maintenance of the spindle assembly.

[0042] As an optional implementation, see Figure 2 and Figure 4 As shown, the oil inlet 31 of the oil inlet channel 3 is connected to the disassembly and assembly groove 2.

[0043] The oil inlet 31 of the oil inlet channel 3 extends through to one end of the disassembly groove 2. This design eliminates the need to open two ports at the end of the screw body 1, resulting in a compact structure that is easy to process.

[0044] As an optional implementation, see Figure 2 and Figure 4 As shown, the oil inlet channel 3, the disassembly groove 2, and the screw body 1 are arranged coaxially.

[0045] With the above structure, the lubricant is applied from the side of the disassembly groove 2 away from the groove opening (oil inlet 31 of the oil inlet channel 3). The lubricant can enter the inner cavity of the spindle 8 from the oil inlet channel 3 along the axial direction of the screw body 1, thus achieving a lubrication effect.

[0046] As an optional implementation, see Figures 2-4 As shown, the outer edge of the slot of disassembly slot 2 is a planar structure.

[0047] The front end of tools such as wrenches can be inserted into the disassembly slot 2 to facilitate disassembly and assembly. This planar structure can provide a certain degree of support and facilitate the application of force.

[0048] As an optional implementation, see Figure 3 As shown, the disassembly slot 2 is an internal polygonal blind hole.

[0049] In this embodiment, the disassembly slot 2 is a blind hexagonal socket, which makes it easy to insert a common wrench. By cooperating with the disassembly slot 2, turning the wrench can drive the screw body 1 to rotate around its own axis, thereby removing the screw body 1 from the spindle 8.

[0050] As an optional implementation, see Figure 2 and Figure 6 As shown, the screw body 1 includes a threaded section 4 and a guide pin 5, wherein: the threaded section 4 extends into the spindle 8 and is threadedly connected to the spindle 8; the guide pin 5 is fixed to one end of the threaded section 4 away from the disassembly groove 2; the compression spring 7 can be sleeved on the guide pin 5 and abuts against the end face of the threaded section 4; the oil inlet channel 3 passes through the threaded section 4 and the guide pin 5, and the oil outlet 32 ​​of the oil inlet channel 3 is located at one end of the guide pin 5 away from the threaded section 4.

[0051] The threaded section 4 is used to extend into the spindle 8 and be threadedly connected to the spindle 8. The guide pin 5 is used to position the compression spring 7. The guide pin 5 extends into one end of the compression spring 7 and plays a role in preventing the compression spring 7 from tilting. This structure facilitates the extension and retraction of the compression spring 7 along the axis of the spindle 8 and improves the stability of the structure.

[0052] As an optional implementation, see Figure 2 As shown, the guide pin 5 has a chamfered structure 51 at one end away from the disassembly groove 2.

[0053] See Figure 5 and Figure 6 As shown, the chamfered structure 51 facilitates the smooth insertion of the compression spring 7 into the guide pin 5, making assembly easier. During installation, the guide pin 5 provides better guidance when it mates with the compression spring 7, preventing uneven force on the compression spring 7 caused by improper assembly or misalignment.

[0054] As an optional implementation, see Figure 2 As shown, the screw body 1 is provided with an annular groove 6, which is used to engage and fix the pressure cap. The annular groove 6 is located at one end of the screw body 1 near the disassembly groove 2, which facilitates the fixation of the pressure cap.

[0055] The screw body structure of this embodiment, in terms of manufacturing process, includes: 1. Blank cutting; 2. Machining: drilling (pin turning) – tapping – chamfering; 3. Surface treatment: polishing – electroplating. The main process flow is: blank cutting – drilling and tapping – chamfering – polishing – electroplating. It is simple to manufacture and easy to process.

[0056] Example 2:

[0057] See Figure 5and Figure 6 As shown, this embodiment provides a spindle assembly, including a spindle 8, a compression spring 7, and the aforementioned screw body structure. The screw body 1 is threadedly connected to the spindle 8, and the compression spring 7 is located inside the spindle 8 and abuts against the inner end of the spindle 8 and the screw body 1.

[0058] In this embodiment of the spindle assembly, when it is necessary to disassemble the screw body 1 to replace it with a new screw body 1 or the compression spring 7, an auxiliary tool such as a wrench is inserted into the disassembly groove 2 to rotate the screw body 1 and remove it from the spindle 8. Since the disassembly groove 2 is located at the end of the screw body 1 and the groove opening is away from the compression spring 7, when the auxiliary tool such as the wrench is inserted into the disassembly groove 2, the auxiliary tool extends along the axial direction of the screw body 1, without occupying space between adjacent spindle assemblies, facilitating the rotation of the auxiliary tool. When it is necessary to lubricate the spindle 8 with oil, there is no need to disassemble the screw body 1, yarn tube, etc. The oil is added to the oil inlet 31 at the bottom of the disassembly groove 2, and the oil flows into the inner cavity of the spindle 8 through the oil inlet channel 3, lubricating the inner cavity of the spindle 8 and the compression spring 7, greatly saving labor and improving efficiency.
