Description

Technical Field

[0001] This utility model relates to the field of thin-walled part processing technology, specifically a fixture for thin-walled part processing. Background Technology

[0002] Thin-walled parts are components with relatively thin walls and are widely used in many fields such as aerospace, automobile manufacturing, and electronic equipment.

[0003] Currently, when processing irregular thin-walled parts, it is necessary to use a fixture to fix them. However, when traditional fixtures clamp irregular thin-walled parts, the clamping point is subjected to all clamping forces, which may lead to deformation of the clamping point. At the same time, workers need to place the thin-walled part in the center of the fixture to clamp it, which is extremely time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixture for machining thin-walled parts, which has the advantages of clamping force diffusion and positioning structure, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a fixture for processing thin-walled parts, including a fixed plate, a vertical plate fixedly installed on the top of the fixed plate, an electric push rod fixedly installed on the outer wall of the vertical plate, a movable frame fixedly installed on the telescopic end of the electric push rod, a motor fixedly installed on the outer wall of the fixed plate, a sliding plate slidably connected to the inner wall of the movable frame, a flexible connecting strip fixedly installed on the top of the sliding plate, a fixed column rotatably connected to the bottom of the flexible connecting strip, a partition and a limiting column fixedly installed on the inner wall of the movable frame, a spring provided on the outer wall of the limiting column, a double-ended lead screw fixedly installed on the output shaft of the motor, a baffle plate fixedly installed on the inner wall of the fixed plate, a sliding block slidably connected to the inner wall of the fixed plate, a fixed bridge fixedly installed on the top of the sliding block, a spring provided on the inner wall of the fixed bridge, a top plate slidably connected to the inner wall of the fixed bridge, a telescopic frame fixedly installed on the outer wall of the top plate, and a positioning wheel rotatably connected to the bottom of the telescopic frame.

[0006] As a preferred technical solution of this utility model: the number of the sliding block, fixed bridge, spring 2, top plate, telescopic frame and positioning wheel is two, and the two sliding blocks, fixed bridge, spring 2, top plate, telescopic frame and positioning wheel are symmetrically arranged.

[0007] As a preferred technical solution of this utility model: the baffle plate is located above the double-ended lead screw, and the baffle plate passes through the sliding block.

[0008] As a preferred technical solution of this utility model: the double-ended lead screw passes through the sliding block, and the double-ended lead screw and the sliding block are threadedly connected, and the sliding block is in contact with the inner wall of the fixed plate.

[0009] As a preferred technical solution of this utility model: the limiting post passes through the sliding plate, and the limiting post and the sliding plate are slidably connected.

[0010] As a preferred technical solution of this utility model: the number of sliding plates and flexible connecting strips is two, and the two sliding plates and flexible connecting strips are symmetrically arranged; the number of fixing posts is several, and the several fixing posts are arranged in a straight line between the two flexible connecting strips.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This fixture for processing thin-walled parts, by activating the electric push rods on both sides, causes the moving frames on both sides to move towards the center. This in turn causes the moving frames to move the flexible connecting strips and fixed posts on the outside towards the center. When the fixed posts come into contact with the outer wall of the thin-walled part, they generate inward pressure, causing the straight arrangement of the fixed posts to bend. This bends the flexible connecting strips, causing the sliding plates on both sides to move. This causes the sliding plates on both sides to move towards the center, compressing the springs and fixing the thin-walled part. This distributes the clamping force throughout the thin-walled part, reducing the probability of deformation.

[0013] 2. The fixture for processing thin-walled parts, by starting the motor, causes the double-ended lead screw to rotate, which in turn causes the two sliding blocks to rotate through the threaded connection between the double-ended lead screw and the two sliding blocks. This causes the two sliding blocks to move the two fixed bridges toward the center, and the thin-walled part located in the center is positioned in the center by the two springs, the top plate, the telescopic frame and the positioning wheel.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 A fixture for machining thin-walled parts includes a fixed plate 1, a vertical plate 2 fixedly mounted on the top of the fixed plate 1, an electric actuator 3 fixedly mounted on the outer wall of the vertical plate 2, a movable frame 4 fixedly mounted on the telescopic end of the electric actuator 3, a motor 11 fixedly mounted on the outer wall of the fixed plate 1, a sliding plate 5 slidably connected to the inner wall of the movable frame 4, a flexible connecting strip 6 fixedly mounted on the top of the sliding plate 5, a fixed column 10 rotatably connected to the bottom of the flexible connecting strip 6, and a partition 7 and a limiter fixedly mounted on the inner wall of the movable frame 4. The outer wall of the column 8 is provided with a spring 9. The output shaft of the motor 11 is fixedly installed with a double-headed lead screw 12. The inner wall of the fixed plate 1 is fixedly installed with a baffle plate 13. The inner wall of the fixed plate 1 is slidably connected with a sliding block 14. The top of the sliding block 14 is fixedly installed with a fixed bridge 15. The inner wall of the fixed bridge 15 is provided with a spring 16. The inner wall of the fixed bridge 15 is slidably connected with a top plate 17. The outer wall of the top plate 17 is fixedly installed with a telescopic frame 18. The bottom of the telescopic frame 18 is rotatably connected with a positioning wheel 19.

[0022] In the above structure, the bottom of the positioning wheel 19 is attached to the top of the fixing plate 1, so that when the positioning wheel 19 moves on the top of the fixing plate 1, the positioning wheel 19 pushes the thin-walled part by attaching with the top of the fixing plate 1.

[0023] In a preferred embodiment, there are two sliding blocks 14, fixed bridges 15, springs 16, top plates 17, telescopic frames 18, and positioning wheels 19, and the two sliding blocks 14, fixed bridges 15, springs 16, top plates 17, telescopic frames 18, and positioning wheels 19 are arranged symmetrically.

[0024] In the above structure, the thin-walled component located in the middle is pushed by moving two sliding blocks 14, fixed bridge 15, spring 16, top plate 17, telescopic frame 18 and positioning wheel 19 towards the middle. The thin-walled component is positioned in the middle of the fixed plate 1 by the positioning wheel 19 outside the fixed bridge 15 on both sides.

[0025] In a preferred embodiment, the baffle plate 13 is located above the double-ended lead screw 12, and the baffle plate 13 passes through the sliding block 14.

[0026] In the above structure, the top of the double-ended lead screw 12 is blocked by the baffle plate 13, so that the debris falling from the top of the double-ended lead screw 12 is blocked by the baffle plate 13, thereby preventing the double-ended lead screw 12 from coming into contact with the debris.

[0027] In a preferred embodiment: the double-ended lead screw 12 passes through the sliding block 14, and the double-ended lead screw 12 and the sliding block 14 are threadedly connected, and the sliding block 14 is in contact with the inner wall of the fixing plate 1.

[0028] In the above structure, by starting the motor 11, the motor 11 drives the double-ended lead screw 12 to rotate, which in turn causes the double-ended lead screw 12 to rotate through the threaded connection with the sliding block 14, thereby causing the sliding block 14 to move the fixed bridge 15.

[0029] In a preferred embodiment: the limiting post 8 passes through the sliding plate 5, and the limiting post 8 and the sliding plate 5 are slidably connected.

[0030] In the above structure, the sliding plate 5 is limited by the limiting post 8, so that the sliding plate 5 will not tilt when it moves, and the sliding plate 5 can only move axially on the outer wall of the limiting post 8 when it moves.

[0031] In a preferred embodiment: there are two sliding plates 5 and two flexible connecting strips 6, and the two sliding plates 5 and flexible connecting strips 6 are symmetrically arranged; there are several fixing posts 10, and the several fixing posts 10 are arranged in a straight line between the two flexible connecting strips 6.

[0032] In the above structure, the movable frames 4 on both sides move towards the center, thereby causing the movable frames 4 to drive the flexible connecting strips 6 and fixed posts 10 on their outer sides to move towards the center. This causes the fixed posts 10 to generate inward pressure when they come into contact with the outer wall of the thin-walled component, causing the straight arrangement of the fixed posts 10 to bend. This causes the flexible connecting strips 6 to bend, causing the flexible connecting strips 6 to drive the sliding plates 5 on both sides to move towards the center, compressing the spring 9 and fixing the thin-walled component.

[0033] Working principle: The thin-walled component is placed on top of the fixed plate 1 and positioned in the middle of the two fixed bridges 15. The motor 11 is then started, causing it to rotate the double-ended lead screw 12. The lead screw 12, through its threaded connection with the two sliding blocks 14, moves the two sliding blocks 14 towards the center. This, in turn, causes the two sliding blocks 14 to move the two fixed bridges 15 towards the center. The movement of the two sliding blocks 14, fixed bridges 15, spring 16, top plate 17, telescopic frame 18, and positioning wheels 19 towards the center pushes the thin-walled component in the center. The positioning wheels 19 on the outside of the two fixed bridges 15 then... The thin-walled component is positioned in the middle of the fixed plate 1. At this time, the two electric actuators 3 are activated, causing the two electric actuators 3 to drive the moving frames 4 on both sides to move towards the middle. This causes the moving frames 4 to drive the flexible connecting strips 6 and the fixed posts 10 on their outer sides to move towards the middle. This causes the fixed posts 10 to generate inward pressure when they come into contact with the outer wall of the thin-walled component, causing the straight arrangement of the fixed posts 10 to bend. This causes the flexible connecting strips 6 to bend, causing the flexible connecting strips 6 to drive the sliding plates 5 on both sides to move towards the middle. This compresses the spring 9, thus fixing the thin-walled component.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
