Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe welding fixture technology, specifically a corrugated pipe welding fixture for vacuum equipment. Background Technology

[0002] In the field of vacuum equipment manufacturing, bellows is a key component that needs to be connected to components such as flanges through welding. The welding quality directly affects the vacuum sealing and operational reliability of the equipment. Due to the thin-walled and multi-corrugated structure of bellows, it is easy to deform during welding due to end positioning deviation and uneven stress on the pipe body.

[0003] Existing welding fixtures for bellows in vacuum equipment have significant limitations: First, the end extension and retraction adjustment function is insufficient, and most rely on fixed structures or simple bolt adjustments, making it difficult to achieve minute and stable position calibration. This results in low alignment accuracy between the bellows and the flange, and defects such as misalignment and incomplete fusion are prone to occur during welding. Second, the pipe body positioning and clamping methods are unreasonable. Common rigid clamps easily cause deformation of the bellows section under stress, while flexible clamps cannot guarantee the coaxiality of the pipe body. Especially when welding slender bellows, pipe body wobbling will further exacerbate the welding difficulty. Third, the fixtures have poor versatility. Special fixtures need to be changed for bellows of different diameters and lengths, and the adjustment process is cumbersome, reducing welding efficiency. These problems together lead to unstable bellows welding quality, becoming a technical bottleneck restricting the production of vacuum equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a bellows welding fixture for vacuum equipment, which has the advantages of easy bellows fixing, convenient end movement and adjustment, and high tube body positioning accuracy. It solves the problem of difficult bellows welding caused by the inconvenience of the existing bellows welding fixture for vacuum equipment in terms of end extension and adjustment fixing and tube body positioning and clamping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A bellows welding fixture for vacuum equipment includes a base, a bracket, a guide assembly, an end clamping assembly, and an end stretching assembly. The bracket is positioned at the center of the upper end of the base. The guide assembly and the end clamping assembly are respectively positioned on both sides of the bracket. The end stretching assembly is positioned on one side of the guide assembly. The guide assembly includes a support rod. The end clamping assembly includes a first track fixing frame. The end stretching assembly includes a second track fixing frame. The first track fixing frame is fixedly positioned at the upper end of the base. A first slider is provided at the upper end of the first track fixing frame. The first slider is slidably connected along a track on the upper surface of the first track fixing frame. A first cylinder is provided on one side of the first slider. A bellows plug is fixedly positioned at the upper end of the first slider.

[0006] Preferably, the output end of the first cylinder is fixedly connected to the first slider, and the cylinder body of the first cylinder is fixedly connected to the upper end face of the first track fixing frame.

[0007] It is worth noting that the first cylinder can stably drive the first slider to slide along the track of the first track fixing frame, thereby driving the bellows plug to accurately adjust its position, facilitating the docking of the bellows end with other components, effectively ensuring the positional accuracy during welding, and at the same time, the cylinder drive improves the automation level and ease of operation of the tooling.

[0008] Preferably, the second track fixing frame is fixedly installed at the upper end of the base; the upper end of the second track fixing frame is provided with a second slider, and the second slider is slidably connected along the track on the upper end surface of the second track fixing frame.

[0009] It is worth noting that the second track fixing frame provides a stable linear guide track for the second slider, which can ensure the straightness of the second slider when sliding, thereby ensuring the accuracy of the end tensioning assembly in stretching the bellows and avoiding the impact of sliding deviation on the welding quality of the bellows.

[0010] Preferably, a second cylinder is provided on one side of the second slider, and the output end of the second cylinder is fixedly connected to the second slider, and the cylinder body of the second cylinder is fixedly connected to the upper end face of the second track fixing frame.

[0011] It is worth noting that the second cylinder, as a power source, can precisely control the moving distance and speed of the second slider, thereby achieving precise adjustment of the position of the end stretching component. This can meet the stretching requirements of bellows of different lengths and improve the versatility and adjustment accuracy of the tooling.

[0012] Preferably, a cylinder frame is provided at the upper end of the second slider, and the cylinder frame is fixedly connected to the second track fixing frame; a third cylinder is provided on one side of the cylinder frame, and the cylinder body of the third cylinder is fixedly connected to the cylinder frame.

[0013] It is worth noting that the cylinder frame provides a stable mounting support structure for the third cylinder, ensuring the stability of the third cylinder during operation, thereby ensuring the accurate transmission of the output force of the third cylinder and improving the reliability of the telescopic plate driving the bellows connection flange.

[0014] Preferably, the output end of the third cylinder is provided with a telescopic plate, and the telescopic plate is fixedly connected to the output end of the third cylinder, and the telescopic plate is provided with a bellows connection flange.

[0015] It is worth noting that the third cylinder can drive the telescopic plate to extend and retract precisely, so that the flange for connecting the bellows can be accurately aligned with the end of the bellows. At the same time, the flange is designed to facilitate connection and fixation with the bellows, providing a stable connection structure for welding, ensuring the relative position of the bellows and the flange remains stable during the welding process, and improving the welding quality.

[0016] Preferably, the upper end of the bellows plug is provided with a clamp; a clamping cylinder and a pressing clamp are respectively provided on both sides of the clamp, and the output end of the clamping cylinder drives the clamp to press down and connect, and the pressing clamp is located above the bellows plug.

[0017] It is worth noting that the clamping cylinder drives the clamp to press down, which can firmly clamp the end of the bellows onto the bellows plug, preventing the bellows from shifting during welding and ensuring the accuracy of welding. Moreover, the clamping structure of the clamp and the pressing clamp can adapt to the clamping requirements of bellows ends of different specifications, improving the applicability of the tooling.

[0018] Preferably, the support rod is disposed at the upper end of the base, and the support rod is connected to the base by bolts; a U-shaped plate is fixedly disposed on one side of the support rod; a clamping piece is disposed on one side of the U-shaped plate, and the clamping piece is connected to the U-shaped plate by bolts.

[0019] It is worth noting that the support rod and the base are fixed with bolts, which makes installation and disassembly convenient and facilitates subsequent maintenance and replacement. The bolt connection between the U-shaped plate and the clamping plate allows the position of the clamping plate to be adjusted according to the specifications of the corrugated pipe, thereby guiding and limiting the corrugated pipe at different positions, ensuring that the corrugated pipe is in the correct position during the welding process, and improving the accuracy and stability of the welding.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The first, second, and third cylinders of this utility model serve as driving components, which can respectively drive the first slider, the second slider, and the telescopic plate to move precisely. Combined with the guiding function of the first and second track fixing frames, the accuracy of the position adjustment of each component is ensured, the degree of automation of the tooling is improved, and the accurate docking of the corrugated pipe end with other components is facilitated.

[0021] The clamps and pressure clamps achieve a stable grip on the end of the bellows through the clamping cylinder. The U-shaped plate and the clamping piece are connected by bolts and their positions can be adjusted. The two work together to adapt to the clamping and guiding needs of bellows of different specifications, avoid the displacement of the bellows during welding, and improve the applicability of the tooling and the welding stability.
