Description

Technical Field

[0001] This utility model relates to the field of presses, and in particular to a highly stable press signal transmission structure. Background Technology

[0002] In the signaling structure of a press, the smooth operation of the drive shaft and the accurate positioning of the sprocket are crucial to ensuring the efficient and reliable operation of the entire system. Traditional press signaling structures often suffer from problems such as high friction in the drive shaft and inaccurate sprocket positioning, resulting in low transmission efficiency, shortened service life, and noise and vibration during operation.

[0003] With the development of industrial automation, presses have been widely used in modern manufacturing. The signaling structure of a press, as a key component, directly affects the operating accuracy and stability of the equipment. Existing press signaling structures have some shortcomings in design and function. For example, the transmission system of some signaling structures is not stable enough, and during long-term operation, problems such as high friction in the drive shaft, inaccurate sprocket positioning, and misalignment can easily occur. This not only leads to a decrease in accuracy but also reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable press signaling structure that offers stable operation and minimal wear.

[0005] The purpose of this utility model is achieved as follows: a high-stability press signaling structure includes a base, a drive shaft, a drive sprocket, a driven sprocket, and a cam controller; the drive shaft is provided with a mounting shaft, which is inserted into and fitted with a first fixed seat and a second fixed seat; a first bearing is provided between the mounting shaft and the first fixed seat, and a second bearing is provided between the mounting shaft and the second fixed seat; the second fixed seat is fixed and pressed on the outside by bolts; the first fixed seat and the second fixed seat are placed on the base, and a rotating bracket is provided between the second fixed seat and the base; a limit step is machined on the mounting shaft between the first fixed seat and the second fixed seat; a limit ring is fixed on the limit step; a drive sprocket is provided on the outside of the limit ring; the drive sprocket is pressed and fixed by a pressure sleeve; the drive sprocket is connected to the driven sprocket through a chain; and the driven sprocket is connected to the cam controller.

[0006] Preferably, the limiting ring is fixed to the limiting step by an internal hex bolt, and four sets of limiting posts are evenly distributed on the side of the limiting ring facing the drive sprocket. Four sets of blind holes are evenly distributed on the side of the drive sprocket facing the limiting ring. The drive sprocket and the limiting ring are inserted and connected through the limiting posts and blind holes.

[0007] Preferably, the pressure sleeve and the mounting shaft are connected by a threaded rotation, and rubber gaskets are provided between the pressure sleeve and the drive sprocket, and on both sides of the limiting ring.

[0008] Preferably, the second fixed base extends downward to have a fixed plate, the fixed plate is fixedly connected to one end of the rotating bracket by two sets of bolts, and the other end of the rotating bracket is fixedly connected to the hinge seat on the base by bolts.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. By setting a first bearing and a second bearing between the mounting shaft and the first fixed seat and the second fixed seat, friction and wear during transmission are effectively reduced, and the smoothness and durability of the structure are improved; and the connection stability between the drive sprocket and the limiting ring is enhanced by inserting and docking the limiting post and the blind hole, preventing the components from loosening due to vibration or external force.

[0011] 2. A rotating bracket is installed below the second fixed seat. The rotating bracket can rotate, allowing the chain to bypass the second fixed seat when it needs to be replaced, thus improving the chain replacement efficiency. Attached Figure Description

Detailed Implementation

[0016] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0017] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] 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.

[0019] like Figure 1-3 As shown, a high-stability press signal transmission structure includes a base 1, a drive shaft 2, a drive sprocket 3, a driven sprocket 4, and a cam controller 5. A mounting shaft 201 is provided on the drive shaft 2, which is inserted into and cooperates with a first fixed seat 6 and a second fixed seat 7. A first bearing 8 is provided between the mounting shaft 201 and the first fixed seat 6, and a second bearing 9 is provided between the mounting shaft 201 and the second fixed seat 7. This effectively reduces friction and wear on the drive shaft 2 during operation, improving transmission efficiency, extending service life, and ensuring the smooth operation of the drive shaft 2.

The drive sprocket 3 and the limiting ring 11 are connected by the insertion of the limiting posts 1101 and the blind holes 301. This ensures the axial position stability of the drive sprocket during operation, prevents axial movement of the sprocket, and improves transmission accuracy and reliability.

[0021] like Figure 1 As shown, the pressure sleeve 12 is connected to the mounting shaft 301 by a threaded rotation. Rubber gaskets are provided between the pressure sleeve 12 and the drive sprocket 3, and on both sides of the limiting ring 11, which reduces noise and vibration during transmission and improves the stability of the structure.

[0022] like Figure 3 As shown, the second fixed seat 7 extends downward to a fixed plate 701. The fixed plate 701 is fixedly connected to one end of the rotating bracket 10 by two sets of bolts. The other end of the rotating bracket 10 is fixedly connected to the hinge seat 101 on the base 1 by bolts. The rotating bracket can rotate, and when the chain needs to be replaced, it can bypass the second fixed seat, thereby improving the chain replacement efficiency.
