Description

Pipeline automatic expansion device

The present invention relates to an accessory technology of a mobile platform, and more particularly to an automatic pipe expansion device.

According to the mobile platform technology for providing two-dimensional or three-dimensional directions, the mobile platform is moved to a predetermined position on a platform by means of appropriate power to drive the moving element through two-dimensional or three-dimensional positioning. It has been disclosed for a number of prior art, but regardless of the conventional driving technology such as a planar motor or a linear motor applied by the conventional mobile platform technology, an appropriate line connection is required between the moving component and the control mechanism, and to protect the In the conventional connection circuit, the flexible technology is coated with a bendable flexible coil to protect the outside of the connecting line, and the connecting line is prevented from being unintentionally damaged during the moving process.

It is a protection technique consisting of a flexible pipe such as a snake tube. Since it has a long length to allow the moving element to move at the maximum moving distance, when the moving element is actuated on the platform, especially the moving distance Due to the short stroke, the pipeline itself lacks proper positioning or storage technology, so that the pipeline can only be arbitrarily oscillated uncontrollably on the platform, which easily interferes with the mobile platform and causes the appearance of the mobile platform to be cluttered.

Therefore, the main object of the present invention is to provide an automatic pipe expansion device which connects a telescopic mechanism between a middle portion of a pipe and a base portion of the mobile platform, and causes the telescopic mechanism to be normally located. In the return position, the pipeline between the telescopic mechanism and the moving member of the moving platform is continuously stretched to obtain the positioning of the pipeline.

In order to achieve the above object, the automatic pipe expansion device provided by the present invention comprises a base portion; a moving member can be driven by the power to move on the base; a flexible pipe is end-to-end with The moving member is connected; and the feature further comprises a telescopic mechanism disposed on the base portion, connected to the middle portion of the flexible tube, and displaceable between a retracted position and an extended position, The flexible tube portion between the moving member and the telescopic mechanism is stretched and positioned.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

Referring to the drawings, an automatic pipe expansion device (10) disclosed in a preferred embodiment of the present invention mainly comprises a base (20), a moving member (30), and a flexible portion. a tube (40) and a telescopic mechanism (50), wherein the specific technical contents of each of the base (20), the moving member (30) and the flexible tube (40) are the same as those disclosed in the prior art. However, it is one of the conventional techniques, and it is not intended to be excessively explained in this embodiment. In other words, in general, the base (20) is platform-shaped and can be used in the conventional mobile platform technology. The platform, when it is powered by a planar motor, forms the base (20) by the stator platform, and when the linear motor is used as the power source, the working platform forms the base (20).

The moving member (30) is driven by a suitable power source to be displaced above the base (20).

The flexible tube (40) is connected at one end to the moving member (30), and the other end is connected to a control mechanism (not shown) located on the base portion (20) for connecting the connection control mechanism with The move The connecting line (not shown) of the piece (30) is covered to provide protection for the connecting line.

The telescopic mechanism (50) is the main technical feature of the present invention. Specifically, the telescopic mechanism (50) includes a connecting portion (51), a force applying portion (52), and a pair of guide wheels (53); the connecting portion (51) is attached to the base portion (20) and connected to a middle portion of the flexible tube (40), and has a linear transmission mechanism (511) of an appropriate length , is fixed on the upper surface (21) of the base (20), a sliding seat (512) is connected to the middle portion of the flexible tube (40), and is slidably disposed on the linear transmission mechanism (511) And reciprocatingly sliding on the linear transmission mechanism (511) between an extended position and a retracted position; the urging portion (52) has an end seat (521) erected on the base of the base (20) (21) above and located on one side of the linear transmission mechanism (511), an elastic member (522) composed of a tension spring is bridged at both ends to the end seat (521) and the sliding seat (512) Upper, 俾 provides elastic force to position the slider (512) normally in the retracted position; the pair of guide wheels (53) are juxtaposed and spaced apart from each other to be pivoted on the table top of the base (20) (21 And with the linear actuator (511) One end of the long axis is adjacently adjacent, and the flexible tube (40) is sandwiched between the pair of guide wheels (53).

The pipe automatic telescopic device (10) can be applied to the mobile platform technology by the composition of the above components, and the flexible pipe is synchronously driven when the moving member (30) is controlled to move. 40) changing the position, and the telescopic mechanism (50) maintains the flexible tube (40) in a state of being stretched between the moving member (30) and the connecting portion (51), and is positioned In order to prevent the flexible tube (40) from swinging as desired in an unpredictable position. In the above, the interference occurs between the other constituent elements of the mobile platform and affects the normal use. Specifically, the present embodiment is a flexible tube between the moving member (30) and the sliding seat (512). 40) a state in which the length is a fixed length, according to which, when the travel distance of the displacement of the moving member (30) is less than or equal to the fixed length, the telescopic mechanism (50) is maintained at the retracted position. a state, as shown in the third figure; and when the displacement travel distance of the moving member (30) is greater than the fixed length, the movement of the moving member (30) is transmitted through the flexible tube (40) The slider (512) is driven to be synchronously displaced, and the displacement distance of the slider (512) is compensated for by the displacement distance of the slider (512), so that the movement of the moving member (30) is not affected. As shown in the four figures, and at the same time, the movement of the carriage (512) synchronously drives the stretching of the elastic member (522), whereby the moving member (30) is displaced to the fixed length range. When the elastic member (522) is retracted, the sliding seat (512) is moved from the extended position to the retracted position to ensure the deflection. Tube (40) to the base portion (20) of the mesa does not like conventional technologies (21) positioned generally unaffected by the absence of any interference caused by the chaotic pendulum.
