Description

Technical Field

[0001] This application belongs to the field of winding head technology, specifically relating to a clamping mechanism, a cradle mechanism, and a winding head mechanism. Background Technology

[0002] The textile industry is a labor-intensive industry, requiring a large number of workers and equipment. Currently, with rising production costs, especially labor and land costs, more and more textile mills are adopting textile equipment that is more automated, compact, and easier to operate and maintain. Currently, a single bearing is commonly used to reduce the width of the cradle mechanism to achieve ultra-small spindle pitch requirements. However, using a single bearing results in poor durability, low coaxiality, and low stability of the cradle mechanism, which does not meet the requirements of robustness and durability for textile equipment. Summary of the Invention

The bearings include a first bearing and a second bearing. The pulley has a groove on its side near the bearing chamber. The first bearing and the second bearing are both located within the bearing chamber, with the bearing chamber partially situated within the pulley groove. This reduces the width of the rocker arm and pulley combined, thus achieving the requirement of an ultra-small spindle pitch. The chuck, facing the rocker arm, has a concave diameter equal to that of the bearing chamber, allowing the chuck to be positioned further closer to the rocker arm, further reducing the width of the rocker arm and chuck combined. By employing two bearings, the first and second bearings, the durability, coaxiality, and stability of the clamping mechanism are significantly improved. The bearing chamber is partially located within the pulley groove, and the chuck is concave on its rocker arm side, which reduces the overall width of the pulley, rocker arm, and chuck, thereby achieving the requirement of an ultra-small spindle pitch.

[0009] Specifically, a groove is made inside the pulley. Based on mechanical calculations and analysis, a suitable bearing is selected. Then, based on the bearing width, the force on the pulley, and the size of the bearing housing, the depth of the groove and the width of the pulley are determined.

[0036] To better understand the above-mentioned objects, features, and advantages of the embodiments according to this application, the embodiments according to this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features of the embodiments according to this application can be combined with each other.

[0037] Numerous specific details are set forth in the following description in order to provide a full understanding of the embodiments according to this application. However, the embodiments according to this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection provided by the embodiments according to this application is not limited to the specific embodiments disclosed below.

[0038] The following reference Figures 1 to 4 Some embodiments provided in this application are described.

[0039] like Figure 1 and Figure 2 As shown, a clamping mechanism 10 according to an embodiment of this application includes a rocker arm 110, a pulley 120, a bearing, and a chuck 140. Specifically, the rocker arm 110 is provided with a bearing chamber 112. The pulley 120 is located on one side of the bearing chamber 112, and a groove is provided on the side of the pulley 120 near the bearing chamber 112, with part of the bearing chamber 112 located within the groove. The bearing includes a first bearing 132 and a second bearing 134. The first bearing is located within the bearing chamber 112, and the second bearing 134 is located within the bearing chamber 112 and on the side of the first bearing 132 away from the pulley 120. The chuck 140 is connected to the side of the rocker arm 110 away from the pulley 120, and the side of the chuck 140 near the rocker arm is recessed.

[0040] The clamping mechanism 10 provided in this embodiment includes a rocker arm 110, a pulley 120, bearings, and a chuck 140. The rocker arm 110 has a bearing chamber 112 for mounting bearings. The bearings include a first bearing 132 and a second bearing 134. The pulley 120 has a groove on its side near the bearing chamber 112, which partially covers the bearing chamber 112. The second bearing 134 and the first bearing 132 are both located within the bearing chamber 112, thereby reducing the width of the rocker arm 110 and pulley 120 to achieve the requirement of ultra-small spindle pitch. The chuck 140, facing the rocker arm, has a concave diameter range equal to that of the bearing chamber 112, allowing the chuck 140 to be further close to the rocker arm, thus reducing the width of the rocker arm 110 and chuck 140. By using two bearings, the first bearing 132 and the second bearing 134, the durability, coaxiality and stability of the clamping mechanism 10 will be significantly improved. The bearing chamber 112 where the first bearing 132 is located is partially contained in the pulley 120. The chuck 140 is recessed on the side facing the rocker arm, which can reduce the overall width of the pulley 120 plus the rocker arm 110 plus the chuck 140, thereby achieving the requirement of ultra-small spindle pitch.

[0041] Specifically, based on mechanical calculations and analysis, a suitable bearing is selected. Then, based on the width of the bearing, the force on the pulley 120, and the size of the bearing housing 112, the depth of the groove and the width of the pulley 120 are determined. The bearing housing 112 is partially contained within the pulley 120, reducing the combined width of the rocker arm 110 and the pulley 120, thereby achieving the requirement of ultra-small spindle pitch.

[0042] In some embodiments, the clamping mechanism 10 further includes a drive shaft 150. The drive shaft 150 is a through shaft inserted into the bearing chamber 112. The drive shaft 150 has a stepped portion on the chuck 140 side, which cooperates with the chuck 140 for positioning the chuck 140.

[0043] Furthermore, the drive shaft 150 is connected to the pulley 120 via a keyway connection. The drive shaft 150 is connected to the chuck 140 via a milling flat connection or a keyway connection.

[0044] In the above embodiment, the clamping mechanism 10 further includes a first retaining ring 162 and a second retaining ring 164. The first retaining ring 162 is disposed between the first bearing 132 and the pulley for fixing the first bearing 132. The second retaining ring 164 is disposed between the second bearing 134 and the bearing housing 112 for fixing the second bearing 134. The dimensions of the first retaining ring 162 are designed to match the outer ring of the first bearing 132. The dimensions of the second retaining ring 164 are designed to match the outer ring of the second bearing 134.

[0045] Furthermore, the bearing housing 112 of the rocker arm 110 is a through hole, within which a first annular groove and a second annular groove are provided. The size of the through hole conforms to the tolerance dimensions of the bearing's outer diameter. The first annular groove and the second annular groove are used to install the first snap ring 162 and the second snap ring 164, respectively.

[0046] In some embodiments, the clamping mechanism 10 further includes a bearing inner ring washer 170, which conforms to the tolerance dimensions of the bearing inner ring. The bearing inner ring washer 170 mates with the first bearing 132 and the second bearing 134, respectively.

[0047] In some embodiments, the clamping mechanism 10 further includes a wave washer 180, which is disposed between the first bearing 132 and the second retaining ring 164. The wave washer 180 is a wave spring washer. The wave spring washer prevents loosening by pressing the connected parts together with its elastic deformation. The wave spring force is small, the force is evenly distributed, and it does not damage the surface of the connected parts.

[0048] In the above embodiments, the clamping mechanism 10 further includes a handle 190, which is connected to the rocker arm 110 and is used to drive the rocker arm 110 to move.

[0049] like Figure 3 As shown, a cradle mechanism 20 according to an embodiment of this application includes a clamping mechanism 10 as described in any of the above embodiments.

[0050] The cradle mechanism 20 provided according to the embodiments of this application includes the clamping mechanism 10 as described in any of the above embodiments, and thus has all the beneficial effects of the clamping mechanism 10 as described in any of the above embodiments, which will not be repeated here.

[0051] like Figure 4 As shown, a winding head mechanism 30 according to an embodiment of this application includes a cradle mechanism 20 as described in any of the above embodiments or a clamping mechanism 10 as described in any of the above embodiments.

[0052] The cradle mechanism 20 provided according to the embodiments of this application includes the cradle mechanism 20 as described in any of the above embodiments or the clamping mechanism 10 as described in any of the above embodiments, and thus has all the beneficial effects of the cradle mechanism 20 as described in any of the above embodiments or the clamping mechanism 10 as described in any of the above embodiments, which will not be repeated here.

[0053] like Figures 1 to 4 As shown, the winding head mechanism 30 according to a specific embodiment of this application mainly consists of a crossbeam, a left cradle mechanism 20, and a right cradle mechanism 20. This application relates to the most critical component of the left cradle mechanism, the left clamping mechanism 10. The left clamping mechanism 10 consists of a pulley 120, a drive shaft 150, a key, a bearing chamber 112, a first retaining ring 162, a first bearing 132, a wave washer 180, a second retaining ring 164, a bearing inner ring washer 170, a second bearing 134, and a chuck 140, among other components.

[0054] To meet the requirements of ultra-small spindle pitch, the cradle needs to be made narrow, yet still able to accommodate the aforementioned components.

[0055] Although a single bearing can be used to reduce the width of the cradle, based on practical and testing experience, using dual bearings significantly improves durability, coaxiality, and stability, and better meets the requirements of textile equipment for robustness and durability.

[0056] To achieve the cradle width requirements for ultra-small spindle pitch, the following work needs to be done:

[0057] First, based on mechanical calculations and analysis, a suitable bearing is selected. Then, based on the bearing width, the force on the pulley 120, and the size of the bearing housing 112, the depth of the bearing hole (groove) and the width of the pulley 120 are determined. The bearing housing 112 is partially enclosed within the pulley 120, reducing the combined width of the rocker arm 110 and the pulley 120, thereby achieving the requirement of ultra-small spindle pitch.

[0058] Secondly, the drive shaft 150 should be a through shaft, with a step on the chuck 140 side for positioning the chuck 140. The drive shaft 150 is connected to the pulley 120 via a keyway. The drive shaft 150 is connected to the chuck 140 via milling or keyway.

[0059] Third, the bearing housing 112 of the rocker arm 110 is a through hole with two slots, the size of which conforms to the tolerance dimensions of the bearing's outer diameter. These two slots are used to install the first retaining ring 162 and the second retaining ring 164, respectively.

[0060] Fourth, the dimensions of the bearing retaining ring must match the design requirements of the bearing outer ring.

[0061] Fifth, the bearing inner ring gasket 170 conforms to the tolerance dimensions of the bearing inner ring.

[0062] Sixth, the chuck 140 facing the cradle has a concave diameter range equal to that of the bearing chamber 112, which allows the chuck 140 to be brought closer to the cradle, thereby reducing the width of the "cradle + chuck 140".

[0063] By using the above six points, the overall width of "pulley 120 + cradle + chuck 140" can be reduced, thereby meeting the requirements for ultra-small spindle pitch.

[0064] In summary, the beneficial effects of the embodiments of this application are as follows:

[0065] 1. The use of dual bearings significantly improves the durability, coaxiality, and stability of the clamping mechanism, making it more in line with the requirements of textile equipment for robustness and durability.

[0066] 2. The bearing housing is partially contained within the pulley, and the chuck is recessed on the side facing the rocker arm. This reduces the overall width of the pulley, rocker arm, and chuck, thus achieving the requirement of ultra-small spindle pitch.
