Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of spinning machine cradle technology, and more specifically to a highly stable cradle. Background Technology
[0002] The high-stability cradle is a key component of the drafting mechanism in spinning frames of textile machinery, playing a crucial role in yarn quality. It transmits pressure by inflating an air bladder. When the air pressure inside the bladder reaches a certain value, the bladder expands and pushes the cradle arm, thereby applying pressure to the rollers and top rollers to control yarn drafting. Because pressure is transmitted through air pressure, relatively consistent pressure can be achieved to a certain extent. The cradle also utilizes the elastic deformation of leaf springs to provide pressure. The leaf springs are pre-deformed during installation, and when the cradle is installed on the spinning frame, the leaf springs attempt to return to their original shape, thus applying pressure to the rollers and top rollers. The advantages of this type of cradle are good parallelism of the upper and lower roller axes and stable pressure.
[0003] However, in practice, it has been noted that the cradle is usually fitted onto the fixed rod of the spinning machine and can rotate on the fixed rod. The cradle is fixed to the fixed rod by the squeezing force of the locking structure. However, the centrifugal force generated when the yarn moves at high speed will exert an upward force on the end of the cradle. When this force is greater than the squeezing force, the end of the cradle will slide circumferentially on the fixed rod, affecting the normal use of the cradle. Utility Model Content
[0004] The purpose of this invention is to provide a highly stable cradle. The cradle has locking structures located on both sides of the fixed rod of a spinning machine inside. The inner side of the locking structures is arranged in a circular array of triangular anti-slip strips, which engage with the anti-slip strips on the fixed rod, thereby improving the stability of the cradle after it is fixed. This solves the technical problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A highly stable rocker arm includes a rocker arm housing, a locking handle is provided on the upper part of the rocker arm housing, and the end of the locking handle extends through the rocker arm housing to the inner end of the rocker arm housing;
[0007] The inner side of the rocker arm housing is provided with an anti-slip clamping seat and a sliding locking seat. The anti-slip clamping seat includes an arc-shaped fixed seat, and a rotating clamping seat is symmetrically provided above the arc-shaped fixed seat. Furthermore, a fixed shaft is movably connected to one end of each rotating clamping seat near the arc-shaped fixed seat.
[0008] The inner sides of the arc-shaped fixing seat and the rotating clamping seat are each integrally provided with triangular anti-slip strips.
[0009] As a further technical solution of this utility model, the cradle housing is provided with a shaft hole, wherein the arc-shaped fixing seat is located below the shaft hole, and the rotating clamping seat is located on both sides of the shaft hole, and the circular holes between the symmetrical rotating clamping seat and the arc-shaped fixing seat are correspondingly provided with the shaft hole.
[0010] As a further technical solution of this utility model, the sliding locking seat includes an inverted U-shaped sliding seat, and the inner side of the sliding locking seat is symmetrically provided with inclined surfaces, while the upper part of the rotating clamping seat slides in cooperation with the inner side of the inverted U-shaped sliding seat.
[0011] As a further technical solution of this utility model, the locking rocker includes an L-shaped pressure rod, one end of which is fixedly connected to an anti-slip handle, and the other end of which extends through the rocker arm housing to the left side of the anti-slip clamping seat. The end of the L-shaped pressure rod away from the anti-slip handle is fixedly connected to a positioning shaft.
[0012] As a further technical solution of this utility model, both ends of the positioning shaft are movably connected to the rocker arm housing, and the rocker arm housing is integrally provided with a grooved claw at one end near the positioning shaft.
[0013] As a further technical solution of this utility model, a tension spring is symmetrically fixedly connected to the upper part of the inverted U-shaped sliding seat, and an extension pressure rod is integrally provided on the side of the inverted U-shaped sliding seat near the locking handle, and the groove claw is attached to the upper part of the extension pressure rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In this invention, by pressing down the L-shaped pressure bar with the anti-slip handle at the hand end, the grooved claw at the other end of the L-shaped pressure bar applies downward pressure to the inverted U-shaped sliding seat. Meanwhile, the tension spring above the inverted U-shaped sliding seat can drive the inverted U-shaped sliding seat to move upward, so that the symmetrically arranged anti-slip clamping seats can be released, thereby stably fixing the cradle housing to the installation position of the spinning machine.
[0016] In this utility model, when the inverted U-shaped sliding seat moves downward, the inclined surface of the inner side of the inverted U-shaped sliding seat cooperates with the inclined surface of the rotating clamping seat, thereby bringing the symmetrically arranged rotating clamping seats closer together. Then, in conjunction with the arc-shaped fixing seat, the cradle shell is fixed by the extrusion force.
[0017] In this invention, the inner sides of both the arc-shaped fixed base and the rotating clamping base are provided with triangular anti-slip strips in a ring array, which mesh with the triangular protrusions on the surface of the fixed rod through the shaft hole, preventing the cradle housing from rotating circumferentially on the fixed rod, thereby improving the stability of the device during use.

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-7 The present invention provides a highly stable rocker arm, including a rocker arm housing 1, a locking handle 4 on the upper part of the rocker arm housing 1, and the end of the locking handle 4 extends through the rocker arm housing 1 to the inner end of the rocker arm housing 1.
[0029] The inner side of the rocker housing 1 is provided with an anti-slip clamping seat 6 and a sliding locking seat 7 respectively. The anti-slip clamping seat 6 includes an arc-shaped fixing seat 61. A rotating clamping seat 62 is symmetrically provided above the arc-shaped fixing seat 61. Furthermore, a fixed shaft 63 is movably connected to one end of each rotating clamping seat 62 near the arc-shaped fixing seat 61.
[0030] The inner sides of the arc-shaped fixing seat 61 and the rotating clamping seat 62 are respectively provided with triangular anti-slip strips 64.
[0031] Furthermore, the cradle housing 1 has a shaft hole 2, wherein the arc-shaped fixing seat 61 is located below the shaft hole 2, and the rotating clamping seat 62 is located on both sides of the shaft hole 2. The circular holes between the symmetrical rotating clamping seat 62 and the arc-shaped fixing seat 61 are correspondingly provided with the shaft hole 2.
[0032] By adopting the above technical solution, the inner sides of the arc-shaped fixed seat 61 and the rotating clamping seat 62 are provided with triangular anti-slip strips 64 in a ring array, which mesh with the triangular protrusions on the surface of the fixed rod through the shaft hole 2, preventing the cradle housing 1 from rotating circumferentially on the fixed rod, thereby improving the stability of the device during use.
[0033] Furthermore, the sliding locking seat 7 includes an inverted U-shaped sliding seat 71, and the inner side of the sliding locking seat 7 is symmetrically provided with inclined surfaces, while the upper part of the rotating clamping seat 62 slides in cooperation with the inner side of the inverted U-shaped sliding seat 71.
[0034] By adopting the above technical solution, when the inverted U-shaped sliding seat 71 moves downward, the inclined surface of the inner side of the inverted U-shaped sliding seat 71 cooperates with the inclined surface of the rotating clamp seat 62, so that the symmetrically arranged rotating clamp seats 62 move closer to each other, and then cooperate with the arc-shaped fixing seat 61 to fix the cradle housing 1 by extrusion force.
[0035] Furthermore, the locking rocker arm 4 includes an L-shaped pressure rod 41, one end of which is fixedly connected to an anti-slip handle 42, and the other end of the L-shaped pressure rod 41 extends through the rocker arm housing 1 to the left side of the anti-slip clamping seat 6. The end of the L-shaped pressure rod 41 away from the anti-slip handle 42 is fixedly connected to a positioning shaft 5.
[0036] By adopting the above technical solution, the L-shaped pressure bar 41 is pressed down by the anti-slip handle 42 at the hand end, so that the groove claw 43 at the other end of the L-shaped pressure bar 41 applies downward pressure to the inverted U-shaped sliding seat 71. The tension spring 72 above the inverted U-shaped sliding seat 71 can drive the inverted U-shaped sliding seat 71 to move upward, so that the symmetrically arranged anti-slip clamping seats 6 can be released, thereby stably fixing the rocker shell 1 to the installation position of the spinning machine.
[0037] More specifically, both ends of the positioning shaft 5 are movably connected to the rocker arm housing 1, and the rocker arm housing 1 is integrally provided with a grooved claw 43 at one end near the positioning shaft 5.
[0038] Furthermore, a tension spring 72 is symmetrically fixedly connected to the upper part of the inverted U-shaped sliding seat 71, and an extension pressure rod 73 is integrally provided on the side of the inverted U-shaped sliding seat 71 near the locking handle 4, and the groove claw 43 is attached to the upper part of the extension pressure rod 73.
[0039] Furthermore, the fixed rod of the spinning machine (not shown in the figure) passes through the shaft hole 2, and the rotating clamping seat 62 is symmetrically arranged on both sides of the fixed rod. Moreover, the fixed rod is fixedly connected in a ring array with triangular protrusions corresponding to the triangular anti-slip strips 64, and the triangular anti-slip strips 64 and the triangular protrusions mesh with each other, thereby improving the anti-slip effect at the connection and increasing the stability of the cradle.
[0040] Furthermore, the tension spring 72 is located inside the rocker housing 1, and the end of the tension spring 72 away from the inverted U-shaped sliding seat 71 is fixedly connected to the top of the rocker housing 1. When the L-shaped pressure rod 41 moves upward, the groove claw 43 at the end of the L-shaped pressure rod 41 is released, and then the tension spring 72 drives the inverted U-shaped sliding seat 71 to move upward, thereby releasing the symmetrical rotating clamping seat 62.
[0041] The working principle of this utility model is as follows: In use, first, the fixed rod on the spinning machine is passed through the shaft hole 2. At this time, the cradle housing 1 can rotate on the fixed rod of the spinning machine until the cradle housing 1 is rotated to a suitable position. Then, the anti-slip handle 42 is held and the L-shaped pressure rod 41 is pressed down. The L-shaped pressure rod 41 rotates around the positioning shaft 5 at its end. At this time, the grooved claw 43 at the end of the L-shaped pressure rod 41 presses down on the extension pressure rod 73, thereby causing the extension pressure rod 73 to move downwards. The inclined surface on the inner side of the inverted U-shaped sliding seat 71 cooperates with the inclined surface on the outer side of the rotating clamping seat 62, allowing the rotating clamping seat to... Rotating around the fixed shaft 63, the symmetrical rotating clamping seats 62 move closer together, reducing the space between the arc-shaped fixed seat 61 and the rotating clamping seat 62. This clamps the fixed rod with compressive force, thus fixing the cradle housing 1 to the fixed rod. Furthermore, the triangular anti-slip strip 64, integrally formed by the arc-shaped fixed seat 61 and the rotating clamping seat 62, engages with the triangular protrusion on the fixed rod of the spinning machine, preventing the cradle housing 1 from rotating circumferentially on the fixed rod under external force, thus improving the stability of the device after locking. The structure is simple, the operation is very convenient, and it effectively reduces manual labor intensity.
