Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a metal plate machining positioner. Background Technology

[0002] In the field of sheet metal machining, the positioning device, as a key process equipment, directly affects machining accuracy and production efficiency. Traditional positioning devices mostly adopt fixed clamps or mechanical force balance principles, such as nozzle baffle mechanisms, V-block positioning, and bench vise fixing. Although they can achieve basic positioning functions, they generally suffer from poor specification adaptability. Traditional positioning devices are mostly designed with one clamp per machine, requiring customized clamps for different sheet metal sizes. Chinese patent (publication number CN211277473U) discloses a sheet metal positioning clamp, which has a limited range of adjustment for the sliding adjustment of the positioning column, and requires manual operation, resulting in low efficiency. Therefore, this utility model proposes a positioning device for sheet metal machining to improve the above problems. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of low adjustment efficiency of the existing metal plate machining positioner, thereby providing a metal plate machining positioner.

[0004] To solve the above problems, this utility model provides a metal plate machining positioner, which includes: Frame, The positioning mechanism has two pairs along the length of the frame, one pair is located at one end of the frame, and the other pair is located away from the end of the frame and is slidably connected to the frame. A conveying mechanism is disposed at the top of the frame, and the conveying mechanism is used to convey metal plates along the length of the frame. A guide adjustment mechanism is provided at one end of the frame where the positioning mechanism is located. The guide adjustment mechanism is used to adjust the alignment of the metal plate conveyed by the conveying mechanism along the width direction of the frame.

[0005] Preferably, the positioning mechanism includes: a first connecting rod and a first guide cylinder, the first guide cylinder and the first connecting rod being rotatably connected, one pair of the first connecting rods of the positioning mechanism being disposed near one end of the frame, and the other pair of the first connecting rods of the positioning mechanism being disposed on the sliding plate.

[0006] Preferably, a pair of slide rails are provided on the inner side of the middle part of the frame, and a slider is provided on each of the pair of slide rails. A mounting plate is provided on the side of the pair of sliders that are close to each other, and the sliding plate is connected between the pair of mounting plates. A fixed rod is provided at one end of the frame away from the positioning mechanism. A first electric cylinder is provided between the fixed rod and the slider. The fixed end of the first electric cylinder is rotatably connected to the fixed rod, and the telescopic end of the first electric cylinder is rotatably connected to the sliding plate.

[0007] Preferably, the conveying mechanism includes: U-shaped plates disposed along the length direction of the frame at the top two edges of the frame, with the inner sides of a pair of U-shaped plates facing each other; A connecting plate is provided at each end of the pair of U-shaped plates. A rotating shaft is provided at the end of the connecting plate away from the U-shaped plate. The rotating shaft and the connecting plate are rotatably connected. A pulley is provided at each end of the rotating shaft. A belt ring is sleeved between the two pulleys at both ends of the U-shaped plate. The top part of the belt ring is located at the top of the U-shaped plate. The top part of the belt ring is used to drive the metal plate to be conveyed along the length of the frame.

[0008] Preferably, a first sprocket is provided near one of the pulleys, and a motor is provided at one end of the frame where the first sprocket is provided. The output shaft of the motor is connected to a second sprocket. The second sprocket and the first sprocket are on the same plane, and a chain ring is sleeved between the first sprocket and the second sprocket.

[0009] Preferably, the guiding adjustment mechanism includes: a positioning plate, one end of the positioning plate near the positioning mechanism being provided with two sides of the frame, and the other end of the positioning plate away from the positioning mechanism being provided with a second connecting rod, and a second guide cylinder being rotatably connected to the second connecting rod. The positioning plate is also vertically provided with a guide plate, one end of the guide plate being close to the second guide cylinder, and the other end of the guide plate being inclined towards the inner side of the frame.

[0010] Preferably, the first guide cylinder and the second guide cylinder are uniformly shaped as an inverted frustum.

[0011] The metal plate machining positioner provided by this utility model has the following beneficial effects: 1. This utility model uses two pairs of positioning mechanisms arranged along the length of the frame. The positioning plates along the length of the frame can be positioned by adjusting these two pairs of positioning mechanisms. One pair of positioning mechanisms is installed at one end of the frame, and the other end is slidably connected to the frame away from the end with the positioning mechanism installed, thus allowing for length-direction adjustment. The conveying mechanism transports the metal plate along the length of the frame, so that one end of the metal plate abuts against the end with the positioning mechanism installed, and the other pair of positioning mechanisms abuts the other end of the metal plate. A guide adjustment mechanism is located near the end of the frame close to the positioning mechanism. The guide adjustment mechanism is used to adjust the centering of the metal plate along the width of the frame during the conveying process, thereby achieving adjustment of the metal plate along its length and width directions and improving adjustment efficiency. 2. This utility model also uses the telescopic movement of the first electric cylinder to adjust the position of the sliding plate relative to the frame, thereby realizing the adjustment of the two positioning mechanisms; 3. This utility model also allows for the adjustment of the length and width of the metal plate as it moves towards one end of the frame via the conveying mechanism. Since the length and width of the plates vary depending on their specifications, the length can be adjusted using two pairs of positioning mechanisms. During the width adjustment process, since the two second guide cylinders are located during the conveying process of the conveying mechanism, if one end of the metal plate contacts one of the second guide cylinders while the other maintains a gap, rolling friction is generated between the second guide cylinders during the contact process. This causes the adjusting guide plate to move to the other side along the width direction of the frame during the conveying process. Afterward, the front end of the metal plate contacts between a pair of guide plates and gradually aligns with the center, thereby completely adjusting the length and width of the metal plate.

[0014] like Figure 1-4 As shown, this utility model provides a metal plate machining positioner, which includes: The frame 1 includes two pairs of positioning mechanisms arranged along its length: one pair located at one end of the frame 1, and the other pair located away from the end of the frame 1 and slidably connected to it. A conveying mechanism is located at the top of the frame 1 and is used to convey metal plates along its length. A guide adjustment mechanism is located near the end of the frame 1 where the positioning mechanisms are located and is used to adjust the alignment of the metal plates conveyed by the conveying mechanism along the width of the frame 1. Figure 1-4 As shown, a metal plate machining positioner includes a frame 1 that supports and mounts the entire device. Two pairs of positioning mechanisms are arranged along the length of the frame 1. The positioning plate 16 along the length of the frame 1 can be positioned by adjusting the two pairs of positioning mechanisms. One pair of positioning mechanisms is installed at one end of the frame 1, and the other end is slidably connected to the frame 1 away from the end where the positioning mechanism is installed, thereby adjusting the length direction. A conveying mechanism conveys the metal plate along the length of the frame 1, so that one end of the metal plate abuts against the end where the positioning mechanism is installed, and the other end of the metal plate abuts against the other end through the other pair of positioning mechanisms. A guide adjustment mechanism is set at the end of the frame 1 near the positioning mechanism. The guide adjustment mechanism is used to adjust the centering of the metal plate along the width direction of the frame 1 during the conveying process of the conveying mechanism, thereby realizing the adjustment of the metal plate along its length and width directions and improving the adjustment efficiency.

[0015] In some implementations, such as Figure 1-4 As shown, the positioning mechanism includes: a first connecting rod 2 and a first guide cylinder 3. The first guide cylinder 3 and the first connecting rod 2 are rotatably connected. One end of the first connecting rod 2 of the positioning mechanism is located near the frame 1. The connection between the first connecting rod 2 and the frame 1 can be by bolting, welding or bonding. The first connecting rod 2 of the other pair of positioning mechanisms is located on the sliding plate 4. The connection can be by bolting, welding or bonding.

[0016] In some implementations, such as Figure 1-4As shown, a pair of slide rails 5 are provided on the inner side of the middle part of the frame 1. The slide rails 5 and the inner side of the frame 1 can be connected by bolts, welding, or bonding. A slider 6 is provided on each of the pair of slide rails 5, and the slider 6 is slidably connected to the slide rails 5. Mounting plates 7 are provided on the sides of the pair of sliders 6 that are close to each other, and the connection can be by bonding or bolting. A sliding plate 4 is connected between the pair of mounting plates 7. The two ends of the sliding plate 4 are perpendicularly connected to the mounting plates 7, and the connection can be by bolting. This links the two sliders 6 together. When the sliding plates 4 move relative to each other, the sliders 6 at both ends slide on the two slide rails 5. This achieves a change in the position of the sliding plate 4 relative to the frame 1, thereby changing the distance between the two pairs of positioning mechanisms, thus achieving centering and positioning of the metal plate along its length. A fixed rod 8 is provided at the end of the frame 1 away from the positioning mechanism. A first electric cylinder 9 is provided between the fixed rod 8 and the slider 6. The first electric cylinder 9 is commercially available. The fixed end of the first electric cylinder 9 is rotatably connected to the fixed rod 8, and the telescopic end of the first electric cylinder 9 is rotatably connected to the sliding plate 4. Through the telescopic movement of the first electric cylinder 9, the position of the sliding plate 4 relative to the frame 1 is adjusted, thereby achieving the adjustment of the two positioning mechanisms.

[0017] In some implementations, such as Figure 1-4 As shown, the conveying mechanism includes: U-shaped plates 10 disposed along the length of the frame 1 at the top two edges of the frame 1; the connection between the U-shaped plates 10 and the frame 1 can be by bolting, welding, or bonding; the inner sides of a pair of U-shaped plates 10 are arranged opposite each other; connecting plates 11 are respectively disposed at both ends of the pair of U-shaped plates 10, and their connection can be by bolting or bonding; a rotating shaft 12 is respectively disposed at the end of the connecting plate 11 away from the U-shaped plate 10; the rotating shaft 12 and the connecting plate 11 are rotatably connected, and... The rotating shaft 12 is provided with pulleys 13 at both ends. The pulleys 13 and belt rings 14 are commercially available. A belt ring 14 is sleeved between the two pulleys 13 at both ends of the U-shaped plate 10. The pulleys 13 drive the belt ring 14 for transmission. The top part of the belt ring 14 is located at the top of the U-shaped plate 10, so that after the belt ring 14 passes through the top of the U-shaped plate 10, it drives the metal plate to be conveyed along the length direction of the frame 1. The top part of the belt ring 14 is used to drive the metal plate to be conveyed along the length direction of the frame 1.

[0018] In some implementations, such as Figure 1-4As shown, a first sprocket is also provided near one of the pulleys 13. A motor 15 is also provided at one end of the frame 1 where the first sprocket is provided. The motor 15 is commercially available. The output shaft of the motor 15 is connected to a second sprocket. The connection between the output shaft of the motor 15 and the second sprocket can be achieved by first connecting the output shaft of the motor 15 to a coupling. The coupling is connected to a rotating rod, and the rotating rod is connected to the second sprocket. The second sprocket and the first sprocket are on the same plane, which makes their transmission smoother. A chain ring is sleeved between the first sprocket and the second sprocket. Driven by the motor 15, the transmission is transmitted to the rotating shaft 12 where the first sprocket is located. The transmission is transmitted to the two pulleys 13 through the rotating shaft 12, so that the two belt rings 14 synchronously transmit the metal plate, realizing the conveying of the metal plate.

[0019] In some implementations, such as Figure 1-4 As shown, the guiding adjustment mechanism includes: a positioning plate 16, with one end of the positioning plate 16 near the positioning mechanism and two sides of the frame 1 connected by bolts or adhesive. A second connecting rod 17 is provided on the end of the positioning plate 16 away from the positioning mechanism; the connection between the second connecting rod 17 and the positioning plate 16 can be by insertion, snap-fit, or bolting. A second guide cylinder 18 is rotatably connected to the second connecting rod 17. A guide plate 19 is also vertically arranged on the positioning plate 16, and its connection can be by bolts or adhesive. One end of the guide plate 19 is near the second guide cylinder 18, and the other end of the guide plate 19... The metal plates are tilted towards the inner side of the frame 1. When the metal plates move towards one end of the frame 1 with the conveying mechanism, the length and width of the plates are different for different specifications. The length can be adjusted by two pairs of positioning mechanisms. During the width adjustment, since the two second guide cylinders 18 are in the conveying process of the conveying mechanism, if one end of the metal plate contacts one of the second guide cylinders 18 while the other is kept at a gap, rolling friction is generated between the second guide cylinders 18 during the contact process. This causes the adjusting guide plate 19 to move to the other side along the width direction of the frame 1 during the conveying process. Then, the front end of the metal plate contacts the pair of guide plates 19 and gradually aligns with the center, thus completely adjusting the length and width of the metal plate.

[0020] In some implementations, such as Figure 1-4 As shown, the first guide cylinder 3 and the second guide cylinder 18 are uniformly shaped into a frustum shape. The frustum shape of the first guide cylinder 3 and the second guide cylinder 18 can adapt to different thicknesses. During the adjustment process, it avoids lifting one corner of the metal plate between the four first guide cylinders 3, and the frustum shape forms a constraint.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
