[0002] In modern industrial production, sheet metal processing is an important part of the manufacturing industry. Sheet metal processing requires precise cutting technology to ensure product quality and material utilization. Four-sided saws are a common device for sheet metal cutting, especially suitable for completing straight line cutting. Four-sided saws can cut in multiple directions at the same time, which greatly improves production efficiency and reduces processing time.

[0003] However, to achieve high-quality cuts, it is vital to ensure consistent and precise board size. In practice, the performance of a four-sided saw depends largely on how accurately and quickly it can position the board.

[0004] Current status and challenges of positioning technology:

[0005] Although four-sided saws are widely used in plate processing, their positioning systems still face some technical challenges, especially in centering. Traditional four-sided saw positioning mechanisms usually rely on manual adjustment or simple mechanical guide systems, which are not only time-consuming but also inefficient, and cannot meet the requirements of fast and accurate centering. In addition, non-automated positioning systems are particularly inefficient when processing large quantities or repetitive high-precision work. Therefore, developing a mechanism that can automatically, quickly and accurately complete centering is the key to improving the efficiency and quality of four-sided saw processing.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0031] See also Figure 1-4 As shown, the utility model provides a technical solution of a four-side saw positioning mechanism: a four-side saw positioning mechanism, comprising a workbench 1, a cavity 2 is opened on the inner side of the workbench 1, the cavity 2 is respectively provided with a displaced center positioning mechanism 3 in the transverse and longitudinal directions, and a driving mechanism 4 is connected to the side of the center positioning mechanism 3;

[0032] The centering positioning mechanism 3 includes a plurality of double bearing seats 301, double-headed screws 302, and positioning plates 304. The double bearing seats 301 are fixedly installed inside the cavity 2. The middle part of the double-headed screw 302 is rotatably connected to the inside of the double bearing seat 301. The two ends of the double-headed screw 302 are designed with threaded portions 303 in opposite directions. The two ends of the double-headed screw 302 are connected to the driving mechanism 4. The positioning plate 304 includes a high-position portion 3041 and a positioning portion 3042. The inner side of the high-position portion 3041 is connected to the threaded portion 303 of the double-headed screw 302 by opening a threaded hole. The positioning plate 304 is located at both ends of the double-headed screw 302. In the specific implementation process, the high-position portion 3041 of the positioning plate 304 can be designed according to the actual height to ensure that the positioning plate The positioning parts 3042 of 304 are at the same height. In addition, the positioning plates 304 on the double-headed screw 302 can be symmetrically arranged on both sides thereof to achieve an ideal centering positioning effect. When centering the plate, the operator needs to place the plate on the workbench 1 first, and ensure that the edge parts of the plate are all located on the inner side of the positioning plate 304, and then rotate the double-headed screw 302 through the driving mechanism 4 so that the positioning plates 304 move toward the center part of the workbench 1 at the same time. When the positioning plates 304 in the width direction clamp the side of the plate, the longitudinal positioning is completed, and when the positioning plates 304 in the length direction clamp the side of the plate, the lateral positioning is completed. If both the lateral and longitudinal positioning are completed, the plate will be centered at this time to ensure the cutting accuracy and improve the cutting quality.

[0033] The driving mechanism 4 includes a bearing support plate 401 and a motor 403. The bearing support plate 401 is arranged at one end of the double-headed screw 302. The other end of the double-headed screw 302 is designed with a first wide-tooth gear 402. The motor 403 is arranged at the opposite end of the bearing support plate 401. The output end of the motor 403 is connected to the second wide-tooth gear 404. The first wide-tooth gear 402 and the second wide-tooth gear 404 are meshed with each other. When the plate is centered, the motor 403 provides power for the rotation of the double-headed screw 302 as an output. When the double-headed screw 302 starts to rotate, the positioning plates 304 on both sides will move toward each other and finally achieve the clamping and positioning effect of the plate. In this process, the bearing support plate 401 plays a stable supporting role to ensure that the double-headed screw 302 maintains correct alignment and smooth rotation during movement.

[0034] A plurality of rollers 5 are arranged on the positioning portion 3042 of the positioning plate 304, and the rollers 5 can provide smooth surface contact during the plate positioning process. In the specific positioning process, the rollers 5 allow the plate to move freely in the non-positioning direction when being positioned horizontally or vertically without damaging the plate due to excessive friction, so that the edge of the plate can be protected even when it is tightened or adjusted, thereby maintaining the integrity and appearance quality of the plate.

[0035] The upper end surface of the workbench 1 is provided with a positioning groove 6, which can provide precise positioning support for small plates to adapt to different plate configurations, thereby improving processing efficiency and enhancing positioning flexibility.

[0036] The first wide-tooth gear 402 and the second wide-tooth gear 404 have the same gear ratio. This design allows the two gears to operate at the same speed and torque output at all times, which helps to avoid mechanical stress and wear caused by speed or torque mismatch. In addition, the same gear ratio simplifies the production process and reduces manufacturing and maintenance costs.

[0037] The positioning portion 3042 of the positioning plate 304 is made of plastic. This design can reduce the weight of the positioning plate 304 itself, thereby reducing the burden on the entire four-sided saw positioning mechanism during operation, improving the response speed and accuracy of the equipment, reducing energy consumption, and extending the service life of the equipment.

[0038] The working principle of the utility model is as follows:

[0039] When processing a plate using a four-sided saw positioning mechanism of the present embodiment, the operator first places the plate on the workbench 1 and ensures that its edge is located on the inner side of the positioning plate 304. Then, by activating the motor 403, the double-headed screw 302 is driven to rotate, so that the positioning plate 304 moves toward the center of the workbench 1. When the positioning plate 304 clamps the side of the plate, the longitudinal and lateral positioning of the plate is completed. This mechanism ensures that the plate is accurately centered before processing by precisely controlling the rotation of the double-headed screw 302 and the movement of the positioning plate 304, thereby greatly improving the cutting accuracy and processing quality.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
