Description

Technical Field

[0001] This application relates to the field of positioning devices in sheet metal processing equipment, and in particular to a sliding positioning table that facilitates the positioning of sheet metal. Background Technology

[0002] In the sheet metal processing industry, the precise and efficient processing of large sheets is a key step in improving product quality and production efficiency. With the increasing automation of manufacturing, the requirements for the sheet metal pretreatment stage are becoming increasingly stringent. In practice, to ensure that the sheets can smoothly enter the machine tool for precision machining, they typically need to be accurately positioned and transported using stable and reliable devices. This demand has driven the research and development of related equipment and technologies, improving work efficiency while ensuring processing accuracy.

[0003] Currently, the industry generally employs various methods to address the challenges of positioning and transporting large-size sheet metal. These include using clamps to directly fix the edges of the sheet metal and then using a robotic arm to grasp and transfer it; using magnetic platforms to attract metal workpieces and then pushing them forward with rolling bearing tracks; and relying on a multi-point vacuum suction cup array to create an overall surface contact constraint pattern combined with linear motor-driven translation. While these traditional methods can meet basic functional requirements to some extent, they all have their own limitations and shortcomings.

[0004] Existing technologies generally suffer from a trade-off between flexibility and stability, especially when dealing with ultra-wide sheet materials, making it difficult to easily adjust the positioning range while maintaining good fixation. Specifically, most solutions lack an effective rapid adaptation mechanism, resulting in prolonged time consumption when changing to different product specifications, impacting the smoothness of continuous production. Furthermore, some designs may pose a risk of localized deformation due to uneven stress, thereby jeopardizing the quality stability of subsequent processes. Utility Model Content

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a sliding positioning stage that facilitates the positioning of sheet metal. A sliding positioning stage for facilitating the positioning of sheet metal includes two support rods slidably connected to a guide rail. The two support rods are parallel to each other, and the two ends of the support rods are provided with limiting components for limiting the corners of the sheet metal. The limiting components include a vacuum adsorption stage, on which two corner cylinders are provided. The corner cylinders are located on adjacent sides of the vacuum adsorption stage and are used to limit the vertical sides of the sheet metal.

[0006] By adopting the above technical solution, when the user positions the board, the board is hoisted onto the vacuum adsorption table, the vacuum adsorption table adsorbs the board and limits its vertical position, the piston rod of the corner cylinder extends and rotates 90 degrees, and the end of the piston rod of the corner cylinder abuts against the two vertical sides of the corner of the board. The four large corner cylinders on the vacuum adsorption table press against the four corners of the board and limit its horizontal position, thereby fixing the entire board to the top of the support rod.

[0007] Preferably, the piston rod end of the rotary cylinder is provided with a push rod, and a rubber pad is provided on the push rod.

[0008] By adopting the above technical solution, when the user uses the device, the push rod is used to abut against the side wall of the plate, and the rubber pad can reduce the wear between the push rod and the plate.

[0009] Preferably, the push rod is threaded to the end of the piston rod of the rotary cylinder.

[0010] By adopting the above technical solution, the user can adjust the position of the push rod through the threaded connection, thereby limiting the movement of plates of different sizes.

[0011] Preferably, a laser positioning device is provided on the side wall of the vacuum adsorption stage. The laser positioning device is located between two corner cylinders and is a crosshair laser used to position the top rod.

[0012] By adopting the above technical solution, when the size of the board changes, the user needs to adjust the position of the top rod. The crosshair laser positioning device can emit positioning lines according to the size of the board, making it easy to adjust the two top rods to the accurate position.

[0013] Preferably, a positioning rod is fixedly connected to the vacuum adsorption stage, an adjusting ring is slidably connected to the positioning rod, a fixing rod is fixedly connected to the adjusting ring, a bolt is threaded onto the adjusting ring, and the laser positioning instrument is connected to the fixing rod.

[0014] By adopting the above technical solution, users can adjust the position of the laser positioning device according to the size of the board, slide the fixing ring along the positioning rod, and then tighten the bolts to accommodate boards of different lengths.

[0015] Preferably, a positioning ring is slidably connected to the fixed rod, and a bolt is threaded onto the positioning ring, with the laser positioning instrument fixedly connected to the positioning ring.

[0016] By adopting the above technical solution, users can adjust the position of the laser positioning device according to the size of the plate, slide the positioning ring along the fixed rod, and then tighten the bolts. This allows the device to adapt to plates of different widths and makes it easy to adjust the position of the top rod in the width direction.

[0017] Preferably, the bottom of the vacuum adsorption stage is fixedly connected to a base, the base has a sliding groove, the sliding groove is slidably connected to a support rod, and multiple bolts are threaded onto the base.

[0021] The following will be combined with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.

[0022] This application provides a sliding positioning stage for facilitating the positioning of sheet metal, as shown in the embodiments below. Figure 1 and Figure 2 The system includes two support rods 1 that are slidably connected to the guide rail 4, and the two support rods 1 are parallel to each other. Limiting components 2 are provided at both ends of the support rods 1. The limiting components 2 have the same structure; here, only one limiting component 2 is used as an example. The limiting component 2 includes a vacuum adsorption stage 21 and two corner cylinders 22. The corner cylinders 22 are located on adjacent sides of the vacuum adsorption stage 21, and their function is to limit the vertical sides of the plate.

[0023] Specifically, the vacuum adsorption stage 21 adopts a planar structure with venting holes and can be made of aluminum alloy or stainless steel, possessing high strength and corrosion resistance. For example, anodized aluminum alloy or 304 stainless steel can be selected as material options. A base 211 is connected to the bottom of the vacuum adsorption stage 21, and the vacuum adsorption stage 21 is mounted to the base 211 by bolts or other fasteners. A sliding groove 212 is provided on the bottom of the base 211. This groove 212 can be designed in a dovetail or T-shape, and it slides smoothly onto the support rod 1, thereby increasing friction and preventing accidental dislodgement. The base 211 also has multiple threaded holes for bolt locking, allowing the entire positioning stage to be flexibly adjusted according to actual needs to adapt to plates of different widths.

[0024] The piston rod end of the corner cylinder 22 is equipped with a push rod 221. The push rod 221 is made of carbon steel and undergoes a heat treatment process to improve its hardness and wear resistance. To avoid damage to the surface of the sheet metal, a soft rubber pad 222 is added to the front end of the push rod 221, which serves as a buffer while also increasing the contact area and enhancing the clamping force. In addition, considering the needs of sheet metal of different thicknesses, the push rod 221 can be adjusted in extension length through a threaded interface design, which allows a single set of equipment to be used in a wider range of applications.

[0025] Next, we will discuss the assembly relationship between the various components: First, place two identical vacuum adsorption stages 21 opposite each other, leaving a certain gap between them; then, use screws to fix them to their respective bases 211; next, insert and calibrate each pair of matching corner cylinders 22 in sequence, ensuring that their movements are coordinated and do not interfere with each other; finally, check that all key nodes are firm and reliable to complete the initial assembly. This compact yet non-interfering spatial layout greatly improves overall operating efficiency and service life.

[0026] Reference Figure 3 A laser positioning device 3 is installed on the side wall of the vacuum adsorption stage 21. The laser positioning device 3 is located between two corner cylinders 22. The laser positioning device 3 is a crosshair laser used to position the top rod 221. A positioning rod 31 is fixedly connected to the vacuum adsorption stage 21. An adjusting ring 32 is slidably connected to the positioning rod 31. A fixing rod 33 is fixedly connected to the adjusting ring 32. A bolt is threadedly connected to the adjusting ring 32. A positioning ring 34 is slidably connected to the fixing rod 33. A bolt is threadedly connected to the positioning ring 34. The laser positioning device 3 is fixedly connected to the positioning ring 34.

[0027] The implementation principle of a sliding positioning table for facilitating the positioning of a board material in this application embodiment is as follows: When positioning the board material, the board material is hoisted onto the vacuum adsorption table 21. The vacuum adsorption table 21 is evacuated to position the board material vertically. The corner cylinder 22 rotates 90 degrees, and the top rod 221 abuts against and supports the side of the board material, pressing against the four sides of the board material to achieve horizontal positioning of the board material.

[0028] When the size of the board changes, the position of the top rod 221 needs to be adjusted. The crosshair laser positioning instrument 3 can emit positioning lines according to the size of the board, which makes it easy to adjust the two top rods 221 to the accurate position. By sliding the fixing ring along the positioning rod 31 and then tightening the bolt, the position of the top rod 221 in the length direction can be adjusted. By sliding the positioning ring 34 along the fixing rod 33 and then tightening the bolt, it can adapt to boards of different widths and make it easy to adjust the position of the top rod 221 in the width direction.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
