Description

Technical Field

[0001] This utility model relates to the field of window frame processing technology, specifically a window frame cross positioning device. Background Technology

[0002] In the manufacturing process of window frames, precise positioning is crucial for ensuring the quality and accuracy of the frames. As window frame projects continue to evolve, positioning solutions are also constantly being improved. Traditional positioning methods have shortcomings in terms of processing complexity, adjustment performance, clamping stability, applicability, and maintenance costs, making it difficult to meet increasingly demanding production requirements. For example, traditional V-block / plane positioning requires precision grinding of the V-shaped bevel, resulting in high processing complexity. Adjustment necessitates disassembling and regrinding the positioning block, which is time-consuming and labor-intensive. Furthermore, it suffers from low repeatability, poor clamping stability, limited applicability, and high maintenance costs. Therefore, it is necessary to design a cross-shaped positioning device for window frames. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a window frame cross positioning device, including a base 1 and a positioning mechanism;

[0022] The positioning mechanism is mounted on the base 1. The positioning mechanism consists of a longitudinal positioning component and a transverse positioning component. The longitudinal positioning component and the transverse positioning component form a cross-shaped reference coordinate system perpendicularly.

[0023] The longitudinal positioning component includes a fixing pin 2 and a wear-resistant plate 3. The fixing pin 2 is fixedly installed on the base 1 by bolts. The wear-resistant plate 3 is disposed on one side of the fixing pin 2 and fits against the base 1, with the contact surface of the wear-resistant plate 3 facing the window. The fixing pin is fixedly installed on the base to restrict the movement and rotation of the window frame in the Y-axis direction. The wear-resistant plate is disposed on one side of the fixing pin and contacts the window frame. Its material is a wear-resistant material with a hardness of HRC50+, such as hardened steel, and the surface is hard chrome plated to improve wear resistance and anti-adhesion performance of the frame.

[0024] The lateral positioning component includes an adjustable stop 4, which is located in the vertical direction of the longitudinal positioning component, and the bottom of the adjustable stop 4 is slidably connected to the base 1.

[0025] In this invention, the wear-resistant plate 3 includes an elastic support base 5, a floating connecting block 6, and a wear-resistant plate body 7. The elastic support base 5 is fixed above the base 1 and has a compression spring 8 inside. The floating connecting block 6 is hinged to the top of the elastic support base 5 by bolts, with the hinge axis extending along the width direction of the window frame. The wear-resistant plate body 7 is fixed to the outside of the floating connecting block 6. The compression spring inside the elastic support base pushes the floating connecting block, causing the wear-resistant plate to produce an elastic displacement of 0.01-0.1mm in the Z-axis direction. This compensates for wear caused by long-term use in real time, avoids positioning deviation due to wear accumulation, and ensures that the repeatability accuracy is maintained within ±0.015mm. The contact surface of the wear-resistant plate body 7 has a slight inclination angle of 85°-88° with the window frame.

[0026] In this invention, the adjustable stop block 4 is bolted to the base 1. The base 1 has bolt holes, which are elongated holes extending laterally. A spring 9 is provided between the adjustable stop block 4 and the base 1. One end of the spring 9 abuts against the back of the adjustable stop block 4, and the other end is fixed to the base 1, keeping the adjustable stop block 4 in a pre-tightened state and allowing it to slide along the elongated hole. This facilitates adjustment of the position of the adjustable stop block, thereby limiting the movement of the window frame in the X-axis direction.

[0027] In this invention, the longitudinal positioning component has at least two fixing pins along the length of the window frame, and the spacing between adjacent fixing pins is equal; the transverse positioning component has at least one adjustable stop block along the width of the window frame, and the length direction of the adjustable stop block is perpendicular to the width direction of the window frame, so that the two form a surface contact positioning.

[0028] Working principle: During use, the window frame is placed on the base, with its side contacting the fixing pin and wear-resistant plate of the longitudinal positioning component, restricting its movement and rotation in the Y-axis direction. The position of the adjustable stop of the transverse positioning component is adjusted so that it contacts the other side of the window frame, restricting its movement in the X-axis direction. Then, clamping force is applied to the center area of ​​the cross, ensuring uniform force on the window frame, thus completing the positioning. During processing, if the wear-resistant plate wears, the spring-preloaded adjustable stop of the transverse positioning component automatically compensates for the wear, maintaining positioning accuracy.

[0029] In summary, this utility model has a novel structural design. It uses mutually perpendicular positioning elements to form a "cross-shaped" reference coordinate system, and achieves precise positioning of the window frame in a two-dimensional plane through rigid constraints, ensuring the stability of the clamping line and reducing the scrap rate.
