Description

Technical Field

[0001] This utility model relates to the field of limiting tooling, and in particular to a guide rail welding limiting tooling. Background Technology

[0002] A guide rail is a mechanical device used to guide and limit the movement trajectory of an object. A guide rail welding limiting fixture is a special process equipment used to position, fix and limit the position of the guide rail during the welding process. It usually consists of a combination of positioning mechanism, clamping mechanism and limiting mechanism. Through precise positioning and limiting, the guide rail can maintain the correct position and posture during welding, thereby ensuring that the dimensional accuracy and geometric tolerance of the welded guide rail meet the design requirements.

[0003] Most existing limiting fixtures adopt unidirectional fixation. Since the guide rails used in different projects or products vary in size, shape and model, if the fixture is not easy to adjust, it can only be used for guide rails of specific specifications. It cannot be used for guide rails of other sizes or types. This greatly limits the versatility of the fixture. At the same time, it makes it difficult to adjust the positioning and clamping method of the guide rail according to the actual welding process requirements, thus affecting the welding quality.

[0004] Therefore, since most of the existing limiting fixtures adopt unidirectional fixation, which is inconvenient to adjust, it will limit the versatility of the fixtures and cause the fixtures to not be able to fully fit the guide rail, thus affecting the welding quality. A guide rail welding limiting fixture can be designed, and the limiting fixture can be adjusted to make it fully fit the guide rail, thereby improving the welding quality. Utility Model Content

[0005] To overcome the problem that most existing limit fixtures adopt unidirectional fixation, which is inconvenient to adjust, will limit the versatility of the fixtures and cause the fixtures to not be able to fully fit the guide rail, thus affecting the welding quality.

[0006] The technical solution of this utility model is as follows: a guide rail welding limiting fixture, including an operating table; symmetrically arranged at both ends of the operating table are limiting modules for limiting operations from both sides of the guide rail, each limiting module including a rotary motor, a rotary motor installed at one edge of the operating table, a threaded rod fixedly connected to the output end of the rotary motor, a rectangular threaded sleeve threaded on the outer wall of the threaded rod, a rectangular telescopic sleeve fixedly connected to the upper end of the rectangular threaded sleeve, a rectangular column fitted inside the rectangular telescopic sleeve, a drive motor installed at the end of the rectangular column away from the rectangular telescopic sleeve, a rotating column fixedly connected to the output end of the drive motor, a rotating plate provided at the end of the rectangular column away from the rectangular telescopic sleeve, the rotating plate being rotatably connected to the rectangular column through the rotating column, a rectangular snap-fit ​​groove provided on the side of the rotating plate away from the rectangular column, a limiting plate provided on the side of the rotating plate away from the rectangular column, and a rectangular snap-fit ​​block fixedly connected to one side of the limiting plate.

[0007] Furthermore, rectangular sliding grooves are provided at both ends of the upper part of the control panel, and multiple sets of plug-in holes are evenly distributed in the middle of the upper part of the control panel.

[0008] Furthermore, a special limiting mold is provided above the operating table, and the special limiting mold is positioned and snapped into the operating table through a plug hole.

[0009] Furthermore, the threaded rod is rotatably mounted on the operating table via bearings and is positioned along the extension direction of the rectangular slide groove.

[0010] Furthermore, a cylinder is installed at one end of the rectangular telescopic sleeve, and the output end of the cylinder is fixedly connected to the rectangular column.

[0011] Furthermore, the rectangular snap-fit ​​block is positioned and connected to the rotating plate via a rectangular snap-fit ​​slot.

[0012] Furthermore, a fixing stud is transversely inserted in the middle of the rectangular snap-fit ​​block, and fixing nuts are threaded on the outer walls of both ends of the fixing stud. A rubber pad is fixed to the inner side of the limiting plate.

[0013] The beneficial effects of this utility model are as follows: The tooling has an adjustable limiting structure. During welding operations, it can accurately select and assemble a suitable limiting mold according to the specific size, shape, and model of the guide rail. Simultaneously, based on the actual requirements of the guide rail's welding position and angle, the limiting module can be precisely moved, extended, and rotated, thereby achieving high-precision limiting operation of the guide rail. This process effectively and precisely controls the position and angle of the guide rail during welding, ensuring its stable fixation, greatly reducing deviations and displacements during welding, significantly improving the quality and precision of the welded joint, and effectively guaranteeing the straightness of the guide rail. Key parameters such as linearity and flatness strictly meet design requirements, providing a solid guarantee for high-quality guide rail welding. At the same time, the tooling's significant adjustable feature gives it strong adaptability. Regardless of the specifications, size, or shape of the guide rails being welded, only corresponding and convenient adjustments to the tooling are needed to quickly meet the welding requirements of various types of guide rails. This innovative design greatly expands the applicability of the tooling, eliminating the need for frequent replacement or customization of special tooling for different guide rails. This effectively improves the tooling's versatility, reduces the investment cost for enterprises in guide rail welding tooling, and enhances production efficiency and economic benefits.
