Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, and in particular relates to an embedded tube gripper. Background Technology

[0002] Currently, single-spindle tube grippers in the textile machinery field generally adopt a screw-fastened assembly structure. The mainstream design uses multiple screws to fix the tube gripper to the air frame, typically requiring four screws, resulting in a complex structure. Each additional screw requires separate positioning, tightening, and torque verification steps. Furthermore, it demands high operator skill, as loose or corroded screws are common malfunctions. The multi-screw design necessitates individual disassembly and inspection during routine maintenance, increasing downtime. Utility Model Content

[0003] To address the above problems, this utility model provides an embedded pipe gripper.

[0004] This utility model is implemented as follows: An embedded tube gripper includes a tube gripper base, which is snapped with a tube gripper flared end. The flared end and the base are fixed in a snap-fit ​​manner. During the gripping of the yarn tube, if subjected to an accidental impact, the flared end can fall off without damaging the base, effectively protecting it and allowing for reuse. The base is connected to an air frame profile, and a sealing movable air cushion is provided at the air outlet of the air frame profile. An integrated piston is installed inside the base, and the piston gripping the yarn tube adopts an integrated structure to prevent the separate embedded pressure block from falling off during assembly and use. A spring is fitted on the integrated piston. Under the pressure of the spring, one end of the integrated piston is pressed tightly against the sealing movable air cushion, and the other end is inserted into the through hole of the tube gripper flared end. When the air frame profile is inflated, the integrated piston... The piston movement grips the yarn tube. When air is released from the air frame profile, the spring returns to its original position, allowing the gripper to lower the yarn tube. This action is stable and reliable. A first positioning block is provided on the upper part of the gripper base. The first positioning block is fitted into the positioning notch processed in the air frame profile. Positioning notches are made at required intervals on the upper part of the air frame profile. When making the notches, the distance between multiple grippers can be precisely controlled to ensure accurate gripping of the yarn tube. The lower part of the gripper base is provided with a mounting hole, and a second positioning block is provided at the mounting hole. The second positioning block is embedded and connected to the groove of the air frame profile, which can control the assembly height of each gripper base on the air frame profile to be consistent, ensuring that the gripping position of the entire machine on the air frame profile is uniform. Screws and nuts are provided at the mounting hole. The screws pass through the mounting hole and the groove of the air frame profile and are locked with the nuts to firmly install the gripper base onto the air frame profile. The screw at the second positioning block engages with the base of the tube gripper embedded in the air frame profile at the first positioning block to press and seal the movable air cushion, ensuring that the air frame can smoothly grip and release the yarn tube without leakage during inflation and deflation.

[0005] The pipe gripper base is provided with one mounting hole, and the screws and nuts are provided as a set, which improves the working efficiency of the entire assembly line.

[0006] A gasket is provided between the screw and the base of the tube gripper to further ensure that when the base of the tube gripper is assembled onto the air frame profile, the bottom of the piston can be tightly pressed against the sealing air cushion, ensuring that the air frame can smoothly grip and release the yarn tube without air leakage during inflation and deflation.

[0007] This utility model features a separate structure for the pipe gripper base and the pipe gripper flared mouth, effectively improving the service life of the pipe gripper base. It utilizes a first positioning block and a second positioning block to achieve precise positioning of the pipe gripper base on the gas frame profile. A set of screws and nuts is installed in the mounting hole where the second positioning block is located, and washers are added to enhance connection reliability. Through this rational structural design, only one screw is needed for fixing the pipe gripper base, saving three screws compared to common single-spindle pipe grippers, reducing the number of fasteners by 75%. This correspondingly reduces drilling, tapping, and tightening time; reduces the potential risk of missing or incorrect installations; and improves the overall efficiency of the assembly line.

Detailed Implementation

[0009] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0010] like Figure 1-2An embedded pipe gripper is shown, comprising a pipe gripper base 1, wherein a pipe gripper flared end 2 is snapped onto the pipe gripper base 1. The pipe gripper base 1 and the pipe gripper flared end 2 are of a separate structural design. (This design has been publicly disclosed in existing technology, such as application number 201810941612.9) The invention patent for a mechanical yarn gripper (which will not be described in detail here) states that the gripper base 1 is connected to the air frame profile 3. A sealing movable air cushion 5 is provided at the air outlet 4 of the air frame profile 3. An integrated piston 6 is provided inside the gripper base 1. The piston that clamps the yarn tube adopts an integrated structure to avoid the separate embedded pressure block from falling off during assembly and use. A spring is sleeved on the integrated piston. Under the pressure of the spring, one end of the integrated piston 6 is pressed tightly against the sealing movable air cushion 5, and the other end is inserted into the through hole 7 of the gripper's flared mouth. When the air frame profile 3 is inflated, the integrated piston 6 moves to clamp the yarn tube. When the air frame profile 3 is deflated, the spring returns to its original position, allowing the gripper to lower the yarn tube. A first positioning block 8 is provided at the upper part of the air frame profile 3. The first positioning block 8 is fitted into the positioning notch 9 of the air frame profile. Multiple positioning notches 9 are provided on the air frame profile 3 as needed, so multiple pipe gripper bases 1 are installed on the air frame profile 3. The lower part of the pipe gripper base 1 is provided with a mounting hole 10. A second positioning block 11 is provided at the mounting hole 10. The second positioning block 11 is embedded and connected to the groove 14 of the air frame profile. A screw 12 and a nut 13 are provided at the mounting hole 10. The screw 12 passes through the mounting hole 10 and the groove 14 of the air frame profile and is locked with the nut 13. A washer 15 is provided between the screw 12 and the pipe gripper base 1 to firmly install the pipe gripper base onto the air frame profile. The pipe gripper base 1 is provided with one mounting hole 10, and the screw 12 and nut 13 are provided as a set, which improves the working efficiency of the entire assembly line. This utility model, through its reasonable structural design, requires only one screw to fix the base of the pipe gripper, saving three screws compared to common single-spindle pipe grippers, thus reducing the number of fasteners by 75%. It also reduces the time spent on drilling, tapping, and tightening processes, reduces the potential risk of missing or incorrect installations, and improves the work efficiency of the entire assembly line.

[0011] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
