Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a flipping structure for precision parts processing. Background Technology

[0002] In machining, workpiece flipping is a common operation, mainly used to achieve multi-faceted machining or to ensure machining accuracy.

[0003] In the prior art, a search revealed a Chinese patent disclosing "A Flipping Structure for Precision Parts Processing," application number "202420811716.9." This patent mainly includes a base plate, with identical support plates fixedly connected to both outer surfaces of the base plate. Two guide rails and a mounting bracket are fixedly connected to the top of the base plate, with the mounting bracket located outside the guide rails. A placement box is located above the base plate, and a flipping assembly is located on the top of the base plate. A drive motor rotates a threaded rod, causing a moving block to move on one side of the two guide rails, thereby pushing a transfer block to move on the two guide rails. While this patent achieves flipping by having a gear rotate when it contacts multiple teeth on the mounting bracket, and the gear simultaneously rotates a rotating shaft, allowing the placement box connected to the rotating shaft to flip without requiring manual flipping of the processed precision parts, thus reducing safety hazards associated with manual operation, the current flipping structure uses a fixed-specification placement box design, only suitable for processing parts of a single specification, resulting in poor versatility. Furthermore, the use of a gear and rack transmission for flipping means that the position of the placement box may shift as the gear rolls along the rack. This positional drift phenomenon forces processing equipment (such as CNC machine tools and laser processing heads) to adjust their processing coordinates in real time. This is particularly problematic in high-precision machining scenarios, increasing the complexity of the control system and reducing processing accuracy and stability. Therefore, this invention provides a flipping structure for precision parts machining to address the problems mentioned in the background section. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model discloses a flipping structure for precision parts processing, which includes a processing table 1. The bottom of the processing table 1 is provided with a U-shaped movable frame 2, which can be raised and lowered. The bottom of the processing table 1 is fixedly provided with a second cylinder 14 and two guide rods 13. The bottom end of the piston rod of the second cylinder 14 is fixedly connected to the movable frame 2. The movable frame 2 and the guide rods 13 are slidably connected to ensure the stability of the movable frame 2 when it is raised and lowered. Both ends of the movable frame 2 are rotatably connected with a rotating shaft 4. One end of the rotating shaft 4 is fixedly provided with a U-shaped rotating plate 3. One side of the movable frame 2 is provided with a drive assembly for driving one of the rotating shafts 4 to rotate. The drive assembly includes a motor 10 fixed on the movable frame 2, a worm gear 17 fixed on the output shaft of the motor 10, and a worm wheel 16 fixed on one end of the rotating shaft 4 and meshing with the worm gear 17.

[0027] The extension and retraction of the piston rod of the second cylinder 14 drives the movable frame 2 to move up and down. When it is necessary to flip the parts, the sliding rod 6 and adjusting rod 7 on the movable plate 5 work together to clamp the parts. The second cylinder 14 drives the movable frame 2 to move upward, so that the parts are separated from the processing table 1. The motor 10 drives the rotating shaft 4 to rotate through the worm gear 17 and worm wheel 16, which drives the rotating plate 3 and the parts to rotate 180° to complete the flipping operation. After flipping, the parts are positioned on the processing table 1 for the next processing step.

[0028] The rotating plate 3 is equipped with a movable plate 5 inside. Each movable plate 5 is symmetrically slidably connected with a horizontally movable slide rod 6. The slide rod 6 is used to clamp and position the precision parts to be processed. A first cylinder 8 is fixedly installed on one side of the movable plate 5. A connecting plate 9 is fixedly installed at the end of the piston rod of the first cylinder 8. One end of the slide rod 6 is fixedly connected to the connecting plate 9. When the first cylinder 8 extends or retracts, it can drive the slide rod 6 to move synchronously, thereby clamping or releasing the workpiece and achieving rapid clamping and stable holding.

[0029] The top of the machining table 1 is equipped with a positioning assembly for positioning precision parts. The positioning assembly includes an electromagnet 11 embedded in the top of the machining table 1 and multiple positioning pins 12 on top of the electromagnet 11. The positioning pins 12 are made of metal. According to the positioning position of the part, the positioning pins 12 are placed on the electromagnet 11. When the electromagnet 11 is energized, it attracts the positioning pins 12, thus achieving positioning and ensuring the stability of the part's support or positioning during machining. Furthermore, the positioning pins 12 are movable and can be freely adjusted or replaced to suit the positioning points of different parts, thus increasing their applicability.

[0030] An adjusting screw 15 is threadedly connected to the inside of the rotating plate 3, near the bottom. The end of the adjusting screw 15 near the movable plate 5 is rotatably connected to the movable plate 5, and the other end of the adjusting screw 15 is fixed with a hexagonal nut for easy rotation. A slide rail 19 is symmetrically fixed to one side of the movable plate 5, and a guide rail 18 is fixed to one side of each end of the rotating plate 3. The slide rail 19 and the guide rail 18 are slidably connected to ensure the smooth movement of the movable plate 5.

[0031] According to the size and specifications of the precision parts, the horizontal position of the movable plate 5 can be adjusted by rotating the adjusting screw 15, which facilitates the adjustment of the position of the slide bar 6 and the adjusting rod 7, thereby increasing or decreasing the distance between the adjusting rods 7, so as to better suit the clamping and flipping work of parts of different sizes, and has a wider range of applications.

[0032] The slide bar 6 has internal threads at the end closest to the precision component, and an adjusting rod 7 is threaded onto it. Rotating the adjusting rod 7 allows adjustment of its extension length, facilitating adjustments to the clamping contact point based on the specific size and shape of the component for better clamping and positioning. An anti-slip pad, made of high-density rubber, is fixed to the end of the adjusting rod 7 furthest from the slide bar 6, providing protection and preventing damage to the precision component from the force exerted by the adjusting rod 7.

[0033] Both the slide rod 6 and the adjusting rod 7 are non-magnetic structures and can be made of stainless steel to eliminate the magnetism during processing, thereby reducing the influence of the electromagnet 11 on the slide rod 6 and the adjusting rod 7. The movable frame 2 has through slots 20 on the inside of both ends and on the side of the hexagonal nut to ensure the free movement of the adjusting screw 15.

[0034] Working principle: When flipping the parts, the first cylinder 8 moves synchronously, driving the slide bar 6 to clamp and stably hold the workpiece; the second cylinder 14 drives the movable frame 2 upward, separating the parts from the processing table 1. The motor 10 drives the rotating shaft 4 to rotate via the worm gear 17 and worm wheel 16, causing the rotating plate 3 and the parts to flip 180° to complete the flipping operation. After flipping to the correct position, the parts are positioned on the processing table 1 for the next processing step.

[0035] Furthermore, the extension length of the adjusting rod 7 can be adjusted by rotating the adjusting rod 7, which makes it easier to adjust the clamping contact point according to the specific size and shape of the parts, so as to better complete the clamping and positioning. At the same time, the horizontal position of the movable plate 5 can be adjusted by rotating the adjusting screw 15 according to the size and specifications of the precision parts, which makes it easier to adjust the position of the slide rod 6 and the adjusting rod 7, thereby increasing or decreasing the distance between the adjusting rods 7, so as to better suit the clamping and flipping of parts of different sizes, with a wider range of applications and strong applicability.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
