[0029] The scheme is realized through the following technical means:

[0030] Embodiment: in the embodiment, a synchronous opening and closing driving mechanism for a lateral supporting type pipe guide device is given, which can realize effective control of the horizontal translation movement of the two side guide supporting plates 3 provided with supporting bases in the guide device through a simple mechanical transmission structure, ensure that the two side guide supporting plates 3 are synchronized to approach or move away from the pipe to be positioned and guided at the same rate, prevent the guide device from generating a horizontal pushing force on the pipe during clamping and fixing, and thus avoid damage caused by the extrusion deformation of the pipe.

[0031] Specifically, it comprises a fixed bottom base 1, guide plates 2 installed on both sides of the bottom base 1, and a pair of guide support plates 3 movably installed on the guide plates 2, which can move horizontally relative to the guide plates 2, and an opening and closing control assembly 4 is further installed on the bottom base 1, which can drive the two guide support plates 3 to move synchronously inward or outward under the drive of the drive device, realizing the conversion of the guide device between the opening and closing states. The opening and closing control assembly 4 comprises a drive connecting plate 401 that can rotate around a vertical central axis, both ends of the drive connecting plate 401 are provided with opening and closing guide grooves 402 extending in the horizontal direction, and the bottom of the guide support plate 3 is formed with a cylindrical opening and closing guide part 301, which is inserted into the opening and closing guide groove 402 and has the same diameter as the width of the opening and closing guide groove 402, and the opening and closing guide part 301 can move along the opening and closing guide groove 402 while rotating relative to the opening and closing guide groove 402. Of course, it needs to be further explained here that the aforementioned opening and closing guide part 301 cannot be completely fixed and installed on the bottom of the guide support plate 3, but is connected by a slidable clamping structure, so that the opening and closing guide part 301 can reciprocate along the axis direction parallel to the conveying direction of the metal pipe.

Since the two sides of the guide support plate 3 are limited by the guide plate 2, the oblique movement is decomposed into the translation of the guide support plate 3 along the opening and closing guide groove 402 and the translation of the opening and closing guide part 301 relative to the guide support plate 3, thereby realizing the opening and closing translation control of each support seat on the two guide support plates 3.

[0032] The bottom of the guide and support plate 3 is L-shaped, and the two guide and support plates 3 are symmetrically arranged at the center of the bottom of the guide plate 2. A translation guide mechanism 5 is further formed between the two sides of the guide and support plate 3 and the guide plate 2 for guiding the movement of the guide and support plate 3. The bottom of the driving connecting plate 401 is formed with a downwardly protruding cylindrical base column 403, which can be inserted into the central hole of the bottom base 1 and rotate around the bottom base 1. A strip-shaped through slot 201 is further formed in the guide plate 2, and the driving connecting plate 401 is formed with an extension segment 404 which extends outwardly through the strip-shaped through slot 201. A telescopic driving device 6 arranged outside the guide plate 2 and a swing connecting segment 7 are further included, and the two ends of the swing connecting segment 7 are respectively hinged to the output end of the telescopic driving device 6 and the extension segment 404.
