Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for metal parts processing, specifically a limiting support device for metal parts processing. Background Technology

[0002] In the metal parts processing, to ensure the machining accuracy of the parts, it is necessary to provide limiting support to prevent displacement or vibration of the parts during cutting, drilling, grinding and other processing steps. At present, the limiting support devices on the market are single fixed clamps and adjustable fixed clamps. The support width and support angle of the single fixed clamp cannot be adjusted, and it can only be adapted to metal parts of specific shapes and sizes. It has poor versatility. For metal parts of different shapes, it is difficult to achieve full fit support, which can easily lead to uneven force and displacement of the parts during processing, affecting the machining accuracy. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a limiting support device for metal parts processing, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a limiting support device for metal parts processing, comprising a mounting box, two first support plates, two second support plates, and a bidirectional sliding mechanism. The mounting box has two first sliding grooves inside, and each of the two first sliding grooves has a third sliding block slidably connected inside. A sliding limiting plate is fixedly connected to the top of each of the two third sliding blocks. The two first support plates are located inside the mounting box and slidably connected to it. The two second support plates are located inside the mounting box and below the first support plates, and are slidably connected to it. The mounting box is equipped with a bidirectional sliding mechanism, which includes two worm gears and two worms. The worm gears and worms are rotatably mounted inside the mounting box and mesh with each other. A connecting rod is fixedly connected to one side of the two worms that are close to each other. A first bevel gear is fixedly mounted on the outer side of the connecting rod. A first motor is fixedly mounted on one side of the mounting box. A second bevel gear is fixedly mounted on the output end of the first motor and meshes with the first bevel gear. A screw is fixedly connected to one side of each of the two worm gears, and a second sliding block is threadedly connected to the outer side of each of the two screws.

[0005] Preferably, a bidirectional screw is rotatably connected inside the first sliding groove. The bidirectional screw passes through two third sliding blocks and is threadedly connected to them. The third sliding blocks are located on both sides with opposite thread directions of the bidirectional screw. A second motor is fixedly installed inside the mounting box. The output end of the second motor is fixedly connected to one end of the bidirectional screw. The bidirectional screw causes the sliding limit plates on both sides to move towards each other.

[0006] Preferably, square limiting strips and trapezoidal limiting strips are fixedly connected to the outer sides of both the first and second support plates. A square limiting groove is provided on one side of the mounting box. Trapezoidal limiting grooves are provided on the corresponding sides of the inner wall of the mounting box and on the side where the two sliding limiting plates are close to each other. The square limiting strip is located inside the square limiting groove and is slidably connected to it. The trapezoidal limiting strip is located inside the trapezoidal limiting groove and is slidably connected to it, thereby limiting the first and second support plates so that they will not detach from the equipment during movement.

[0007] Preferably, cylinders are fixedly installed on both sides of the interior of the two second support plates, and trapezoidal sliding blocks are fixedly connected to the output ends of the two cylinders. An air outlet pipe is fixedly installed on one side of the two second support plates, and the air outlet pipes are used to connect the two cylinders to the external air circuit, thereby controlling the extension and retraction of the cylinders.

[0008] Preferably, one side of the mounting box has an operating groove and a groove for the air supply pipe to pass through at both ends. A controller is fixedly installed on one side of the mounting box and to the right of the operating groove. A fourth sliding groove is provided on one side of the mounting box. The screw is located inside the fourth sliding groove and is rotatably connected to it. The second sliding block is located inside the fourth sliding groove and is slidably connected to it. The operating groove facilitates the user to adjust the height of the first sliding block.

[0009] Preferably, a V-shaped groove is formed on one side of the top of the first support plate, and a second sliding groove is formed inside the first support plate and on one side of the V-shaped groove. A V-shaped sliding block is slidably connected inside both of the two second sliding grooves, and an electric telescopic rod is installed inside both of the two second sliding grooves. The output end of the electric telescopic rod is fixedly connected to the V-shaped sliding block, so that the device can be used for smaller parts and has a wider range of applications.

[0010] Preferably, a third sliding groove is provided on the side of each of the two second sliding blocks that are far apart from each other. A fourth sliding block is slidably connected inside the third sliding groove. A first sliding block is fixedly connected to one side of the fourth sliding block. An auxiliary ball is fixedly connected to one side of each of the two first sliding blocks. A magnetic plate is provided on the side of the first support plate, the second support plate, and the adjacent side of the first sliding block. The installation of the auxiliary ball makes it easier to move the first sliding block.

[0011] This utility model provides a limiting support device for processing metal parts, which has the following advantages: 1. This limiting support device for processing metal parts first changes the position of the first sliding block by moving the auxiliary ball. When it is located above and completely on one side of the first support plate, the controller controls the output end of the first motor to rotate, causing the second sliding block to drive the first sliding block to slide forward along the screw, pushing the first support plate to one side of the sliding limiting plate. Then, the second motor is controlled to rotate, causing it to drive the sliding limiting plate and the first support plate to move forward, placing the part above the V-groove. If the second support plate is needed, the first sliding block is slid down until it is completely on one side of the second support plate. The movement method is the same as that of the first support plate, enabling the equipment to process different sizes and shapes.

[0012] 2. The limiting support device for metal parts processing extends the electric telescopic rods on both sides through the first motor, causing the two V-shaped sliding blocks to retract inward, or pushes the two trapezoidal sliding blocks toward each other by controlling the cylinders on both sides of the second support plate, making the locking of the equipment more stable and applicable to metal parts of various sizes, thus improving processing efficiency.

[0016] Please see Figures 1 to 10 This utility model provides a technical solution: a limiting support device for metal parts processing, including a mounting box 1, two first support plates 3, two second support plates 8, and a bidirectional sliding mechanism 34. Square limiting strips 6 and trapezoidal limiting strips 9 are fixedly connected to the outer sides of both first support plates 3 and second support plates 8. A square limiting groove 13 is provided on one side of the mounting box 1. An operating groove 23 and a groove for the insertion of an air supply pipe 31 are provided at both ends of one side of the mounting box 1. A controller 17 is fixedly installed on one side of the mounting box 1, located to the right of the operating groove 23. A fourth sliding groove 19 is provided on one side of the mounting box 1. A screw 18 is located inside the fourth sliding groove 19 and rotatably connected to it. A second sliding block 29 is located inside the fourth sliding groove 19 and slidably connected to it. The operating groove 23 facilitates user adjustment of the height of the first sliding block 12.

[0017] Trapezoidal limiting grooves 10 are provided on the corresponding sides of the inner wall of the mounting box 1 and on the side of the two sliding limiting plates 2 that are close to each other. A square limiting strip 6 is located inside the square limiting groove 13 and is slidably connected to it. A trapezoidal limiting strip 9 is located inside the trapezoidal limiting groove 10 and is slidably connected to it, limiting the first support plate 3 and the second support plate 8 so that they will not detach from the equipment during movement. Cylinders 30 are fixedly installed on the corresponding sides of the inner walls of the two second support plates 8. Trapezoidal sliding blocks 15 are fixedly connected to the output ends of the two cylinders 30. An air outlet pipe 31 is fixedly installed on one side of the two second support plates 8. The air outlet pipe 31 is used to connect the two cylinders 30 to the external air passage, thereby controlling the extension and retraction of the cylinders 30.

[0018] The mounting box 1 has two first sliding grooves 4 inside, and a bidirectional screw 21 is rotatably connected inside the first sliding groove 4. The first sliding groove 4 is a through groove that passes through the mounting box 1. The outer side of the bidirectional screw 21 and the outer side of the screw 18 are provided with screw protective sleeves. The bidirectional screw 21 passes through two third sliding blocks 35 and is threadedly connected to them. The third sliding blocks 35 are located on both sides of the bidirectional screw 21 with opposite thread directions. A second motor 20 is fixedly installed inside the mounting box 1. The output end of the second motor 20 is fixedly connected to one end of the bidirectional screw 21. The bidirectional screw 21 causes the sliding limit plates 2 on both sides to move closer to each other. The two first sliding grooves 4 are slidably connected to the third sliding blocks 35. The top of the two third sliding blocks 35 is fixedly connected to the sliding limit plates 2. The two first support plates 3 are located inside the mounting box 1 and are slidably connected to the mounting box 1. The two second support plates 8 are located inside the mounting box 1 and below the first support plates 3, and are slidably connected to the mounting box 1.

[0019] A V-groove 5 is provided on one side of the top of the first support plate 3. A second sliding groove 7 is provided inside the first support plate 3 and on one side of the V-groove 5. A V-shaped sliding block 32 is slidably connected inside both second sliding grooves 7. An electric telescopic rod 33 is installed inside both second sliding grooves 7. The output end of the electric telescopic rod 33 is fixedly connected to the V-shaped sliding block 32, so that the device can be used for smaller parts and has a wider range of applications.

[0020] The mounting box 1 is internally equipped with a bidirectional sliding mechanism 34, which includes two worm gears 24 and two worms 27. Both worm gears 24 and worms 27 are rotatably mounted inside the mounting box 1 and mesh with each other. A connecting rod 28 is fixedly connected to the side of the two worms 27 closest to each other. A first bevel gear 25 is fixedly mounted on the outer side of the connecting rod 28. A first motor 14 is fixedly mounted on one side of the mounting box 1. A second bevel gear 26 is fixedly mounted on the output end of the first motor 14. The first bevel gear 25 and the second bevel gear 26 mesh with each other. Each of the two slide blocks 18 is fixedly connected to one side. The outer sides of the two slide blocks 18 are threaded with second sliding blocks 29. The two second sliding blocks 29 are provided with third sliding grooves 11 on the side away from each other. The third sliding grooves 11 are slidably connected to the inside of the third sliding grooves 11. A first sliding block 12 is fixedly connected to one side of the fourth sliding block 36. Auxiliary balls 16 are fixedly connected to one side of each of the two first sliding blocks 12. Magnetic plates are provided on the adjacent sides of the first support plate 3, the second support plate 8, and the first sliding block 12. The installation of auxiliary balls 16 makes it easier to move the first sliding block 12.

[0021] In summary, this limiting support device for metal part processing allows for the selection of a corresponding support plate based on the shape of the metal part to be processed. For example, if the first support plate 3 is selected, the first sliding block 12 is moved upwards along the third sliding groove 11 by the auxiliary ball 16 until it is completely positioned on one side of the first support plate 3. Because the fourth sliding block 36 is in contact with the inner side of the third sliding groove 11, the resulting friction prevents the first sliding block 12 from shifting without external force. This allows the first sliding block 12 to move along with the second sliding block 29. The controller 17 then controls the output of the first motor 14 to rotate, causing it to drive the second bevel gear 26 and the first bevel gear 25 to rotate. The first bevel gear 25 drives the connecting rod 28 and the worm 27 to rotate. Because the worm 27 meshes with the worm wheel 24, it drives the worm wheel 24 to rotate, causing the screws 18 on both sides to rotate. This causes the second sliding block 29 and the first sliding block 12 to slide forward. The first sliding block 12 then drives the first support plate 3, causing the trapezoidal limiting strip 9 on one side of the first support plate 3 to slide inside the trapezoidal limiting groove 10 until it completely slides into the trapezoidal limiting groove 10 on one side of the sliding limiting plate 2. The second motor 20 drives the bidirectional screw 21 to rotate, causing the third sliding block 35 to move. This causes the sliding limiting plates 2 and the first support plate 3 on both sides to slide forward until both sides reach the second sliding limit plate 29. When the inner side of the first support plate 3 is in contact with the metal part, the movement stops. If it is necessary to retract the first support plate 3, simply control the output end of the second motor 20 to rotate in the opposite direction, driving the sliding limit plate 2 back to its original position. Since the first support plate 3 and the first sliding block 12 are both provided with magnetic plates on their adjacent sides, they are attracted together. Controlling the first motor 14 to rotate in the opposite direction will move the second sliding block 29 to the initial position, and drive the first sliding block 12 and the first support plate 3 to move in the initial direction until one side of the first support plate 3 is in contact with the inner side of the mounting box 1, thus completing the storage of the first support plate 3. If the second support plate 8 is selected, simply lower the first sliding block 12. Move the part to one side completely aligned with the second support plate 8. The other steps are the same as above. If the part is too small, if the first support plate 3 is used, the controller 17 controls the electric telescopic rods 33 inside the second sliding grooves 7 on both sides to extend outward, thereby driving the V-shaped sliding blocks 32 on both sides to move outward. The movement stops when the inner side of the V-shaped sliding block 32 is in contact with the outer side of the part. If the second support plate 8 is used, the controller 17 controls the cylinders 30 inside the second support plates 8 on both sides to push the trapezoidal sliding blocks 15 on both sides to move towards each other until the inner side of the trapezoidal sliding block 15 is in contact with the side of the part. This completes the limiting and support of the part.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
