AI Technical Summary
When welding, it is difficult to ensure welding accuracy, which leads to the space composed of guide rods being easily stuck when filling objects. Due to the different expansion coefficient and thickness of the material, the welding deformation is difficult to control, and the aging and calibration process takes a long time.
The new non-welded structure of self-positioning guide rods is adopted. Through the design of the front and rear reinforcement plates, the coordination of limit holes, blind holes and screw holes is used to tighten the guide rods and guide groove rods by screws to achieve welding-free tightening.
The structure is simple, and there is no welding at the connection of each component. The orientation device can be completely tightened by its own structure and screws alone, reducing welding deformation, ensuring straightness accuracy, and shortening manufacturing time.

[0036] A plurality of front rib plates 10 and a rear rib plate 20 are spaced apart from each other, a guide groove rod 40 passes through the grooves on the plurality of front rib plates 10 and is connected to the positioning block 22 on the rear rib plate 20; the four guide rods pass through the limiting holes 12 on the plurality of front rib plates 10 and are then passed into the blind holes 24 on the rear rib plate 20, and a screw 60 for locking the guide rod 30 and the guide groove rod 40 is installed in the screw hole 50.
[0037] It is understood that in the present application, a plurality of front ribs 10 and a rear rib 20 are parallel and distributed at a certain spacing, which can be distributed at equal spacing or at unequal spacing, wherein a plurality of front ribs 10 are located on the front side of the rear rib 20. It should be understood that the terms "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature.
[0038] In addition, the limiting holes 12 and the blind holes 24 in the present application correspond to one another in a straight line when the plurality of front rib plates 10 and the rear rib plates 20 are arranged, ensuring that the guide rod 30 can smoothly pass through the plurality of corresponding limiting holes 12 and the blind holes 24.
