Description

Technical Field

[0001] The utility model relates to the field of braiding machine structures, in particular to a quick-changing spring mechanism for spindles and a spindle. Background Art

[0002] The spindle is an important component structure of a braiding machine. A braiding machine has multiple groups of spindles, which process multiple strands of wire into a final product. The spring spindle structure in the prior art is shown in the patent document with the publication number CN2495669Y. One end of the right column 18 (i.e., the slide bar) with a spring 10 is fixed on the runway rod 7, and the other end is fixed to the porcelain eye frame 19. Since different braided finished products use different braided wires, the tension requirements are also different, so it is often necessary to replace the springs sleeved on the slide bar to meet the tension adjustment of different wires. As shown in the aforementioned reference, the two ends of the slide bar in the prior art are fixed on the slide bar frame (in the aforementioned reference, the slide bar seat is an integral structure formed by accessories such as the porcelain eye frame 19 and the runway rod 7). When it is necessary to replace the spring sleeved on the slide bar, the slide bar frame needs to be disassembled for replacement. For example, in the aforementioned reference, the porcelain eye frame 19 needs to be removed, and other accessories connected to the porcelain eye frame 19 also need to be removed, resulting in a very complicated and cumbersome process of replacing the spring. Utility Model Content

[0003] In view of the above problems, the utility model provides a spring mechanism for quickly replacing a spindle and a spindle.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A quick-change spring mechanism for a spindle, comprising:

[0006] A mounting seat, one end of the mounting seat having a mounting structure and the other end having a positioning groove;

[0007] A mounting rod, one end of which is mounted on the mounting structure and the other end of which is embedded in the positioning groove;

[0008] A spring, which is sleeved on the mounting rod;

[0009] The pressing plate is rotatably arranged on the mounting seat, and has a notch area and a non-notch area. When the notch area corresponds to the positioning groove, the pressing plate will not limit the mounting rod, and one end of the mounting rod embedded in the positioning groove can be moved out of the positioning groove. When the non-notch area corresponds to the positioning groove, the pressing plate limits the mounting rod, and the mounting rod cannot be moved out of the positioning groove.

[0010] Fasteners are used to secure the pressure plate to the mounting base.

[0011] The steps for replacing the spring in the present application are as follows: loosen the fastener, then rotate the pressure plate to align the notch area of ​​the pressure plate with the positioning slot (the fastener can also be re-locked at this time), push the mounting rod from the inside to the outside, so that one end of the mounting rod moves out of the positioning slot, and the mounting rod forms a certain angle, so that the spring can be smoothly pulled out of the mounting rod. After replacing the new spring, press the spring downward to ensure that the spring is under the mounting rod seat, press the mounting rod into the positioning slot from the outside to the inside, rotate the pressure plate so that the non-notch area of ​​the pressure plate corresponds to the mounting rod, and finally lock the fastener to complete the operation of quickly replacing the spring.

[0012] The present application can quickly unlock the mounting rod by changing the angle of the pressure plate, thereby enabling quick replacement of the spring, which is more convenient to use.

[0013] In one embodiment of the present invention, the pressing plate is a circular plate with a notch, and the notch is the notch area.

[0014] In one embodiment of the present invention, the pressure plate has a locking working position and an unlocking working position, and a side of the pressure plate in contact with the mounting rod has an arc-shaped limit slot. When the pressure plate is in the locking working position, the limit slot cooperates with the mounting rod.

[0015] The design of the limiting slot enables the pressure plate to better limit the installation rod.

[0016] In one embodiment of the present invention, the unlocking working position and the locking working position of the pressing plate are 90° apart.

[0017] In one embodiment of the present invention, the fastener is a bolt.

[0018] In one embodiment of the present invention, the fastener is a hexagon socket screw.

[0019] In one embodiment of the present invention, the mounting rod is an elastic mounting rod.

[0020] In one embodiment of the present invention, the mounting structure includes a mounting slot, and one end of the mounting rod is inserted into the mounting slot.

[0021] In one embodiment of the present invention, the pressing plate is located at the top of the mounting seat.

[0022] The present application also discloses a spindle, including the quick-change spring mechanism of the spindle described above, the spindle also including a guide rod fixed on the mounting seat and a sliding seat slidably arranged on the guide rod, the mounting rod passes through the sliding seat, one end of the spring is against the pressure plate or the mounting seat, and the other end is against the sliding seat.

[0023] The beneficial effect of the utility model is that the application can quickly unlock the installation rod by changing the angle of the pressure plate, so that the spring can be quickly replaced, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
