Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing, and in particular to an aluminum alloy processing positioning device. Background Technology

[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry. Aluminum alloys have low density but high strength, which is close to or exceeds that of high-quality steel. They also have good plasticity. During the processing of aluminum alloy products, clamping and positioning devices are required to fix the aluminum alloys.

[0003] Currently, planar clamping is commonly used for positioning in aluminum alloy processing. Clamps such as clamps are used to clamp the two sides of the aluminum alloy workpiece. However, the clamping part of the positioning device needs to be bent and fit the surface of the aluminum alloy workpiece, resulting in poor adaptability. Conventional planar clamping structures can only be adapted to workpieces with relatively flat appearance, and the clamping and positioning effect on irregular aluminum alloy parts is poor, resulting in low practicality. Utility Model Content

[0004] To overcome the problem that the existing aluminum alloy processing positioning device has a flat clamping plate structure, which can only be used for workpieces with relatively flat appearance, and has poor clamping and positioning effect on irregular aluminum alloy parts, resulting in low practicality.

[0005] The technical solution of this utility model is as follows: an aluminum alloy processing positioning device, including a base, a positioning platform, and a movable seat. The lower ends of the positioning platform are fixedly connected to the base on both sides by fixing plates. Two movable seats are symmetrically arranged on both sides of the upper end of the positioning platform. The surface of the movable seat is provided with a through hole, and a connecting rod is slidably installed in the through hole. One end of the connecting rod extends to the inner side of the movable seat and is fixedly installed with a clamping head. The other end of the connecting rod extends to the outer side of the movable seat and is fixedly connected with a stop block. A double-ended lead screw is provided between the two fixing plates. Displacement blocks are threaded onto both ends of the surface of the double-ended lead screw. A mounting frame is fixedly installed on the upper end of the movable seat, and an adjusting pressure plate is provided on the inner side of the mounting frame.

[0006] Preferably, when the movable seat moves, the clamping heads on both sides move closer together and contact the surface of the aluminum alloy part, so that the multiple clamping heads adapt to the curvature of the aluminum alloy part surface and fit better on the workpiece, making it easy to adapt to aluminum alloy parts of different shapes. At the same time, the pressure plate moves downward to limit the position of the clamping heads, prevent loosening, and improve practicality.

[0007] Preferably, the connecting rods are evenly spaced, and an adjusting spring is sleeved on the outside of the connecting rod. The two ends of the adjusting spring are fixedly connected to the clamping head and the movable seat, respectively.

[0008] Preferably, the threads at both ends of the double-ended lead screw are opposite and have the same pitch. The two ends of the double-ended lead screw are rotatably connected to the fixed plate, and the left end of the double-ended lead screw extends to the outside of the fixed plate and is fixedly installed with an adjusting motor. The lower end of the adjusting motor is fixedly connected to the base.

[0009] Preferably, the surface of the positioning platform is provided with a sliding groove, in which a connecting block is slidably installed. The lower end of the connecting block is fixedly connected to the displacement block, and the upper end of the connecting block is fixedly connected to the movable seat. The sliding groove and the movable seat correspond one-to-one.

[0010] Preferably, the surface of the positioning platform has guide grooves on both sides of the slide groove, and guide blocks are slidably installed in the guide grooves. The guide blocks are fixedly connected to both sides of the lower end of the movable seat.

[0011] Preferably, the mounting bracket has a U-shaped structure design, and an adjusting cylinder is fixedly installed at the upper end of the mounting bracket. The output end of the adjusting cylinder is fixedly connected to the upper end of the adjusting pressure plate.

[0012] Preferably, the upper end face of the movable seat is provided with an extension groove, which is connected to the through hole. The lower end face of the adjusting plate is provided with a pressure block, which corresponds to the connecting rod. The lower end of the pressure block is designed with an arc shape, and the upper end of the connecting rod surface is provided with a friction plate.

[0013] The beneficial effects of this utility model are:

[0014] This aluminum alloy processing positioning device features multiple clamping heads connected by adjusting springs. As the movable seat moves, the clamping heads contact the surface of the aluminum alloy part. The adjusting springs are compressed according to the curvature of the aluminum alloy part's surface, allowing the clamping heads to better conform to the surface. This facilitates positioning of aluminum alloy parts with different structures, ensures clamping stability, and expands the device's applicability. Furthermore, after clamping, an adjusting cylinder pushes the adjusting pressure plate downwards, causing the pressure block to contact the connecting rod surface. This restricts the position of the connecting rod, preventing the clamping heads from loosening and further enhancing stability. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of an aluminum alloy processing positioning device, including a base 1, a positioning platform 2, and a movable seat 3. The lower ends of the positioning platform 2 are fixedly connected to the base 1 on both sides via fixing plates 4. Two movable seats 3 are symmetrically arranged on both sides of the upper end of the positioning platform 2. A through hole is formed on the surface of the movable seat 3, and a connecting rod 5 is slidably installed in the through hole. One end of the connecting rod 5 extends to the inner side of the movable seat 3 and a clamping head 6 is fixedly installed thereon. The connecting rods 5 are evenly spaced, and an adjusting spring 51 is sleeved on the outer side of the connecting rod 5. The two ends of the adjusting spring 51 are fixedly connected to the clamping head 6 and the movable seat 3, respectively. The other end of the connecting rod 5 extends... A stop block 7 is fixedly connected to the outside of the movable seat 3. A double-ended lead screw 8 is set between the two fixed plates 4. Displacement blocks 9 are threaded onto both ends of the surface of the double-ended lead screw 8. A mounting bracket 10 is fixedly installed on the upper end of the movable seat 3. An adjusting pressure plate 11 is set on the inner side of the mounting bracket 10. When the movable seat 3 moves, the clamping heads 6 on both sides move closer to each other and contact the surface of the aluminum alloy part. This allows the multiple clamping heads 6 to adapt to the curvature of the aluminum alloy part surface, better fit the workpiece, and easily adapt to aluminum alloy parts of different shapes. At the same time, the adjusting pressure plate 11 moves downward to limit the position of the clamping heads 6, prevent loosening, and improve practicality.

[0023] Please see Figure 1 and Figure 2 In this embodiment, the threads at both ends of the double-ended lead screw 8 are opposite and have the same pitch. The two ends of the double-ended lead screw 8 are rotatably connected to the fixed plate 4 respectively. The left end of the double-ended lead screw 8 extends to the outside of the fixed plate 4 and is fixedly installed with an adjusting motor 81. The lower end of the adjusting motor 81 is fixedly connected to the base 1. The adjusting motor 81 drives the double-ended lead screw 8 to rotate, and the two displacement blocks 9 move synchronously, thereby adjusting the position of the movable seat 3 and realizing clamping and positioning.

[0024] Please see Figure 2In this embodiment, the surface of the positioning platform 2 is provided with a sliding groove 21, and a connecting block 22 is slidably installed in the sliding groove 21. The lower end of the connecting block 22 is fixedly connected to the displacement block 9, and the upper end of the connecting block 22 is fixedly connected to the movable seat 3. The sliding groove 21 and the movable seat 3 correspond one-to-one. The surface of the positioning platform 2 is provided with guide grooves on both sides of the sliding groove 21, and guide blocks are slidably installed in the guide grooves. The guide blocks are fixedly connected to both sides of the lower end of the movable seat 3. When the displacement block 9 moves, the movable seat 3 is moved synchronously through the connecting block 22, so that the two movable seats 3 come together, which facilitates the clamping and positioning of the aluminum alloy parts. The guide block slides in the guide groove to achieve guiding and limiting.

[0025] Please see Figure 1 , Figure 4 , Figure 5 In this embodiment, the mounting frame 10 has a U-shaped structure design. An adjusting cylinder 101 is fixedly installed on the upper end of the mounting frame 10. The output end of the adjusting cylinder 101 is fixedly connected to the upper end of the adjusting pressure plate 11. An extension groove 31 is opened on the upper end surface of the movable seat 3. The extension groove 31 and the through hole are connected to each other. A pressure block 111 is provided on the lower end surface of the adjusting pressure plate 11. The pressure block 111 corresponds to the connecting rod 5 one by one. The lower end of the pressure block 111 has an arc-shaped structure design. A friction plate is provided on the upper end of the surface of the connecting rod 5. The adjusting cylinder 101 drives the adjusting pressure plate 11 to move downward, so that the pressure block 111 enters the through hole through the extension groove 31 and contacts the friction plate on the surface of the connecting rod 5, forming a stable clamping limit, preventing the connecting rod 5 from sliding, and ensuring the stability of the clamping head 6 during clamping.

[0026] During operation, the aluminum alloy part is placed on the positioning table 2, and the adjusting motor 81 drives the double-headed lead screw 8 to rotate. The two displacement blocks 9 move synchronously, and the movable seats 3 move synchronously through the connecting block 22, so that the two movable seats 3 come together. The clamping head 6 contacts the surface of the aluminum alloy part and adapts to the curvature of the aluminum alloy part surface. The elasticity of the spring 51 is adjusted so that the multiple clamping heads 6 fit better on the workpiece, which is convenient for adapting to aluminum alloy parts with different shapes. Then, the adjusting cylinder 101 drives the adjusting pressure plate 11 to move downward, so that the pressure block 111 enters the through hole through the extension groove 31 and contacts the friction plate on the surface of the connecting rod 5 to form a stable clamping limit, preventing the connecting rod 5 from sliding and ensuring the stability of the clamping head 6 during clamping. After processing, the adjusting cylinder 101 first drives the adjusting pressure plate 11 to reset, and then the adjusting motor 81 rotates in the opposite direction, and the two movable seats 3 on both sides separate, making it convenient for personnel to remove the aluminum alloy part.

[0027] Through the above steps, when the movable seat 3 moves, the clamping heads 6 on both sides move closer to each other and contact the surface of the aluminum alloy part. This allows the multiple clamping heads 6 to adapt to the curvature of the aluminum alloy part surface, better fit the workpiece, and easily adapt to aluminum alloy parts of different shapes. At the same time, the pressure plate 11 is adjusted to move downward to limit the position of the clamping heads 6, prevent loosening, and improve practicality. This solves the problem that the existing aluminum alloy processing positioning device with a flat clamping plate structure can only adapt to workpieces with relatively flat appearance, and has poor clamping and positioning effect on irregular aluminum alloy parts, resulting in low practicality.
