Description

Technical Field

[0001] The present invention relates to the transmission technology field of an adjustment device with a split structure in an automated production line, and particularly relates to an error correction self-locking transmission docking device. Background Art

[0002] In the current high-frequency welded pipe production line technology field, since the processing specifications applicable to the production line are becoming more and more extensive, quick-change devices for changing processing specifications are often added to the production line. Then, the docking problem between the mill adjustment module and the replacement module will be involved. In the existing technology applications, since a transmission shaft is provided between the mill adjustment module and the replacement module to achieve synchronous transmission between the two, if the docking of the transmission shaft fails, the transmission actions between the mill adjustment module and the replacement module will be asynchronous, which will have a great impact on the size adjustment of the mill adjustment module. And when the mill adjustment module and the replacement module are split from each other, the adjustment input shaft of the mill adjustment module will be in a freely rotatable state without being locked and restricted. In this way, due to the relatively complex production environment, sometimes the adjustment input shaft will be accidentally touched by the operator or the adjustment input shaft will be driven to rotate passively due to certain vibrations. The rotation of the adjustment input shaft will cause adjustment deviation of the adjustment module, which will have a great impact on the accuracy of the mill. Therefore, in order to solve such problems, it has become inevitable for those skilled in the art to develop an error correction self-locking transmission docking device that can lock the adjustment input shaft after the mill adjustment module and the replacement module are split from each other and ensure correct docking and synchronous transmission. Summary of the Invention

The extending direction of the anti-rotation key z is parallel to the axis direction of the input shaft 1. At least one anti-rotation groove cz is further provided on the first clutch body a. The anti-rotation groove cz can be engaged with the anti-rotation key z so that the first clutch body a cannot rotate relative to the housing k but can slide relative to the housing k along the extending direction of the anti-rotation key z.

[0007] According to one aspect of the embodiment of the present invention, a first spring a1 is further provided. The first spring a1 is sleeved outside the second spring b2 and is provided on one side of the first clutch body a.

[0008] According to one aspect of the embodiment of the present invention, the pressure sleeve y and the sliding sleeve s are connected through a pressure sleeve sliding key yj. The pressure sleeve y can slide on the sliding sleeve s and rotate synchronously with the sliding sleeve s.

[0030] Such as Figure 3 、 Figure 4 and Figure 5As shown, this embodiment provides an error-correcting self-locking drive docking device that can lock the adjustment input shaft and ensure synchronous transmission after the rolling mill adjustment module and the replacement module are disassembled from each other. By setting a telescopic and sliding sliding sleeve, a first clutch body and a pressure sleeve between the input shaft and the housing of the original structure, the rotation of the input shaft is locked. When the disassembly shaft is inserted into the sliding sleeve, the clutch opens and the input shaft can rotate. When the disassembly shaft abuts against the pressure sleeve, the clutch closes and the input shaft cannot rotate. The specific implementation in this embodiment may include a housing k, an input shaft 1, and a disassembly shaft c. The housing k is installed at one end of the adjustment device p and is hollow cylindrical. At least one anti-rotation key z is also provided along the axial direction of the inner wall of the cylindrical shape inside it. The anti-rotation key z extends uniformly along the center line direction of the hollow cylindrical housing k. A circular plate-shaped first clutch body a is also provided inside the housing k. The first clutch body a is set as a hollow circular plate with a hole in the center. At least one anti-rotation groove cz is provided on its outer circumference. The anti-rotation groove cz can be engaged with the anti-rotation key z. The first clutch body a is placed inside the housing k and the anti-rotation groove cz is engaged with the anti-rotation key z. The first clutch body a can slide relative to the housing k along the extension direction of the anti-rotation key z but cannot rotate relative to the housing k. In addition, a detector t is also provided. The detector t is arranged at the position where the first clutch body a is located and penetrates the housing k to detect whether the first clutch body a remains in the original stationary position.

[0031] The input shaft 1 is arranged on one side of the adjustment device p and protrudes outward from the inside of the adjustment device p. A sliding key j and a sliding sleeve s are also provided on the input shaft 1. The sliding sleeve s is set as a hollow tubular transmission sleeve. A key groove running through the entire sliding sleeve s is also provided inside it. The sliding sleeve s is sleeved on the input shaft 1 and the sliding key j is inserted into the key groove. The sliding sleeve s can slide on the outer surface of the input shaft 1 along the extension direction of the sliding key j, and the input shaft 1 can be driven to rotate synchronously by rotating the sliding sleeve s. In addition, a disc-shaped second clutch body b is also provided on the outer circumferential surface of the sliding sleeve s. The working surface of the second clutch body b is perpendicular to the center line of the sliding sleeve s and is fixedly installed with the sliding sleeve s. The second clutch body b is arranged parallel to the first clutch body a. The second clutch body b can be attached to the first clutch body a and be stationary relative to each other through friction.

[0032] In this embodiment, according to one aspect of this embodiment, a cylindrical hollow shell-shaped pressure sleeve y is further provided on the outer side of the sliding sleeve s. The pressure sleeve y is sleeved on the sliding sleeve s, and at least one pressure sleeve sliding key yj is further provided on the outer surface of the sliding sleeve s. Corresponding to the number of the pressure sleeve sliding keys yj, pressure sleeve key grooves are further provided on the inner cylindrical surface of the pressure sleeve y. The pressure sleeve key grooves can be engaged with the pressure sleeve sliding keys yj. The pressure sleeve y being sleeved on the sliding sleeve s and the pressure sleeve key grooves being engaged with the pressure sleeve sliding keys yj can enable the pressure sleeve y to slide along the central axis of the sliding sleeve s, and when the sliding sleeve s is rotated, the pressure sleeve y can be driven to rotate synchronously. The pressure sleeve y passes through the housing k and abuts against the first clutch body a.

[0033] In addition, a first spring a1 and a second spring b2 are further provided inside the housing k. The pressure sleeve y is sleeved on the sliding sleeve s, the sliding sleeve s is sleeved on the input shaft 1. The first clutch body a is embedded inside the housing k through the mutual engagement of the anti-rotation key z and the anti-rotation groove cz and is sleeved on the sliding sleeve s. The first spring a1 is provided between the first clutch body a and the outer wall of the adjustment device p. The second clutch body b is disposed on the outer side of the first clutch body a relative to the housing k. The first spring a1 is sleeved on the second clutch body b, and the first clutch body a can be pressed against the inner wall of the housing k by the tension of the first spring a1. The second spring b2 is provided between the second clutch body b and the outer wall of the adjustment device p, and the second spring b2 can press the second clutch body b towards the first clutch body a and enable relative static between the second clutch body b and the first clutch body a through friction.

[0035] Figure 11 It is a left view schematic diagram of the split shaft c in the preferred embodiment of the present invention.

[0036] As Figure 10 and Figure 11 shown, according to one aspect of the embodiment of the present invention, a keyhole groove yc and a pressure hole groove yy are further provided on the pressure sleeve y. Both the keyhole groove yc and the pressure hole groove yy can penetrate the pressure sleeve y along the central axis direction of the pressure sleeve y. A transmission key cj and a pressure key ya are further provided on the split shaft c. When the split shaft c is inserted into the sliding sleeve s, the transmission key cj can pass through the keyhole groove yc and be aligned with the sliding key j, and the pressure key ya can pass through the pressure hole groove yy and abut against the sliding sleeve s.

[0038] Figure 5 It is a schematic diagram of the retraction of the pressure sleeve y in the preferred embodiment of the present invention.

[0039] As Figure 4 and Figure 5 shown, according to one aspect of the embodiments of the present invention, the specific working process is as follows. When the splitting shaft c fails to dock with the input shaft 1, that is, the splitting shaft c is not correctly inserted into the sliding sleeve s, the end of the splitting shaft c will abut against the end of the pressure sleeve y. As the splitting shaft c continues to move towards the input shaft 1, the pressure sleeve y will be pushed towards the housing k by the splitting shaft c. At the same time, the pressure sleeve y will press the first clutch body a and drive the second clutch body b and the sliding sleeve s in parallel to overcome the tension of the first spring a1 and the second spring b2 and synchronously move towards the inside of the housing k. When the insertion action of the splitting shaft c stops, the first clutch body a, the second clutch body b, and the sliding sleeve s stop moving synchronously. At this time, the detector t detects that the first clutch body a has left its stationary position and immediately feeds back a signal of the docking failure between the splitting shaft c and the input shaft 1 to the computer. At this time, since the first clutch body a and the second clutch body b continue to be pressed against each other, the input shaft 1 cannot rotate.

[0043] Figure 9 is another cross-sectional schematic diagram of the pressure key ya pressing the sliding sleeve s in a preferred embodiment of the present invention.

[0044] As Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, according to one aspect of the embodiments of the present invention, the specific working process is as follows. When the splitting shaft c docks successfully with the input shaft 1, that is, the splitting shaft c is correctly inserted into the sliding sleeve s, the transmission key cj can pass through the key hole groove yc and be aligned with the sliding key j, and the pressure key ya can pass through the pressure hole groove yy and abut against the sliding sleeve s. As the splitting shaft c continues to move towards the housing k, the pressure key ya continues to push the sliding sleeve s to slide towards the housing k and gradually enables the second clutch body b to overcome the tension of the second spring b2 and separate from the first clutch body a. At this time, the detector t does not detect that the first clutch body a has left its original stationary position, indicating that the splitting shaft c and the input shaft 1 are docked successfully. At this time, rotating the splitting shaft c can achieve the synchronous rotation of the splitting shaft c and the input shaft 1.

[0045] Figure 1 is a schematic diagram of the basic overall layout structure in an embodiment of the present invention.

[0046] Figure 2 It is a schematic diagram of the basic structure of the overall layout of another embodiment of the present invention.

The protection scope of the present invention is defined by its claims and covers all embodiments falling within its scope and their obvious equivalent variations.
