Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and is specifically designed as a heavy-duty precision disc-shaped workpiece rotation detection platform. Background Technology

[0002] Heavy-duty precision disc-shaped workpieces are quite large, generally exceeding 100kg, and require batch processing and 100% inspection. Full-surface flaw detection and surface inspection are part of their processing steps. The existing flaw detection method is to place the workpiece on the inspection platform. After one side is inspected, the workpiece needs to be manually flipped 180 degrees to continue inspecting the other side. Because these workpieces are precision parts, they cannot be bumped or scratched, and the surrounding area must be protected. However, these workpieces are large and heavy, and bumps are inevitable during manual flipping and inspection. Moreover, it is time-consuming and labor-intensive, and the scratches caused by human intervention will affect the yield rate. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a heavy-duty precision disc-shaped workpiece rotation detection platform with simple structure and convenient detection.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: A heavy-duty precision rotary inspection platform for disc-shaped workpieces includes a support and a rotary platform. Its characteristic is that a bearing seat is provided on the upper surface of each of the two parallel opposite sides of the upper frame beam at the top of the support. The bearing seats are located in the middle of the upper frame beam, and bearings are installed inside the bearing seats. A rotating shaft is installed inside the bearings. A fixed seat is provided on one side of the bearing seat, on the side of the upper frame beam. The two fixed seats are diagonally positioned. An anti-rotation fork rod is installed inside the fixed seat. The rotary platform has a rectangular central plate, and each of the four sides of the central plate has a vertical plate. The two opposite sides of the vertical plate are respectively connected to the rotating shafts in the two fixed seats. The vertical plates and the rotating shafts can be fixed by welding, keying, or gear connection, allowing the rotary platform to rotate 360 ​​degrees around the two rotating shafts. A vertical plate fork rod hole is provided on each side of the vertical plate at a point corresponding to the anti-rotation fork rod. The four vertical plate fork rod holes allow the rotary platform to rotate... After a 180-degree rotation, the anti-rotation fork can be inserted and limited. A circular hole is located in the center of the central plate of the rotating platform. Multiple fastening bolts are evenly distributed around the central plate around the hole, penetrating and fixing the bolts to the central plate. L-shaped pressure plates are located on both sides of the central plate. The longer plate of the L-shaped pressure plate has a groove, which the pressure plate fits onto the fastening bolts on both sides of the central plate. The shorter end face of the pressure plate faces the central plate. An upper end cover and a lower end cover are also provided. It is a cylindrical tube with a central opening. The bottom of the upper and lower end caps are provided with annular pressure plate edges. The pressure plate edges of the upper and lower end caps are pressed against the pressure plate on the rotating platform. The top of the upper and lower end caps are provided with annular top end face platforms. Each top end face platform is provided with a handle. Support pads are evenly provided on the inner wall of the cylinder of the upper and lower end caps. Support pads are provided on the inner wall of the top end face platforms of the upper and lower end caps. Multiple elliptical holes are opened on the cylinder wall of the upper and lower end caps.

[0005] The beneficial effects of this utility model are: the heavy-duty precision disc-shaped workpiece rotary inspection platform has a simple structure and is easy to use. By rotating the platform 360 degrees, the workpiece can be placed in one go for comprehensive inspection of both the top and bottom sides, saving time and effort. The anti-rotation fork rod can fix the platform in place to prevent it from loosening, ensuring inspection safety and quality. The upper and lower end covers cover both sides of the workpiece, and the inner walls of the upper and lower end covers are equipped with support pads to ensure that the workpiece is not scratched, enabling the workpiece to be inspected efficiently and safely.

Detailed Implementation

[0014] Example, see attached document Figure 1-6The heavy-duty precision disc-shaped workpiece rotation inspection platform consists of a trapezoidal support 2 with four feet fixed to four base feet 1 at the bottom. The four base feet 1 are fixed to the ground. The top of the support 2 has two parallel upper beams 2-1. A bearing seat 9 is provided on the upper end face of each upper beam 2-1. The bearing seats 9 are located in the middle of the upper beam 2-1. The two bearing seats 9 are symmetrically arranged. A bearing 10 is installed in the bearing seat. The rotating shaft 11 is installed in the bearing 10 and rotates within the bearing 10. A fixed seat 12 is provided on the upper beam 2-1 on one side of each bearing seat 9. The two fixed seats 12 are diagonally positioned. An anti-rotation fork rod 13 is installed inside the fixed seat 12. The anti-rotation fork rod 13 can be spring-loaded and elastically pulled out of the fixed seat 12 by the spring. Alternatively, a through hole can be provided at the outer end of the anti-rotation fork rod 12. A cotter pin can be inserted into the through hole to limit the anti-rotation fork rod 13. These are known technologies and will not be described in detail. The method is to lock the anti-rotation fork rod 13 in place, so that the anti-rotation fork rod 13 is fixedly locked in the vertical plate fork rod hole 3-2, thereby stabilizing the rotating platform 3. The rotating platform 3 has a rectangular central plate 3-1, and a vertical plate is fixed on each of the four sides of the central plate 3-1. The rectangular central plate 3-1 and the surrounding vertical plates form a rotating platform. Two vertical plates 3-3 that are close to the two upper beams 2-1 are respectively connected to the rotating shafts 11 in the fixed base 12. The rotating shafts 11 can be welded to the vertical plates 3-3, fixed by key connection, or fixed by gear transmission. These are all known technologies. The rotating shafts 11 are fixed to the vertical plates, so that the rotating platform 3 can rotate 360 ​​degrees around the two rotating shafts 11. Each vertical plate 3-3 has a vertical plate fork hole 3-2 on each side. The vertical plate fork holes 3-2 are located on both sides of the center position where the vertical plate 3-3 connects to the rotating shaft 11. The vertical plate fork holes 3-2 correspond to the positions of the anti-rotation fork rods 13. When the rotating platform 3 rotates to the working position, the two diagonally opposite anti-rotation fork rods 13 can be inserted into the two diagonally opposite vertical plate fork holes 3-2. When the anti-rotation fork rods 13 are made of tension springs, pulling the anti-rotation fork rods 13 outwards will... When the tension spring connected to the anti-rotation fork 13 is compressed, and the anti-rotation fork 13 is aligned with the vertical plate fork hole 3-2, the anti-rotation fork 13 is released. The tension spring connected to the anti-rotation fork 13 rebounds, and the elastic force inserts the anti-rotation fork 13 into the vertical plate fork hole 3-2. The elasticity of the tension spring is large enough to ensure that the anti-rotation fork 13 does not fall out of the vertical plate fork hole 3-2. The two sets of diagonally arranged anti-rotation fork 13 can increase the stability of the rotating platform and prevent accidents during platform rotation and workpiece inspection. Alternatively, a pin hole can be provided at the outermost end of the anti-rotation fork 13. After the anti-rotation fork 13 is inserted into the vertical plate fork hole 3-2, a cotter pin is inserted into the pin hole to stabilize the rotating platform 3. After the rotating platform 3 rotates 180 degrees, the anti-rotation fork 13 is inserted into another pair of diagonally arranged vertical plate fork holes 3-2, and then the other side of the workpiece is inspected.A circular hole is made in the center of the central plate 3-1 of the rotating platform 3. Four fastening bolts 14 are evenly distributed around the central plate 3-1 around the circular hole. The fastening bolts 14 penetrate and are fixed to the central plate 3-1. Four L-shaped pressure plates 8 are provided on the upper and lower sides of the central plate 3-1. The long plate of the L-shaped pressure plate 8 has a sliding groove. The eight pressure plates 8 respectively fit into the sliding grooves on the fastening bolts 14 on both sides of the central plate 3-1. The end face of the short plate of the pressure plate 8 faces the central plate 3-1, which can limit the pressing and compaction of the end cover. Fasteners are used to fasten the pressure plates 8 to all the fastening bolts 14, thereby fixing the pressure plates 8 and firmly fixing the end cover and the workpiece. An upper end cover 7 and a lower end cover 5 are also provided. The upper end cover 7 and the lower end cover 5 are cylindrical with a through hole. The height of the upper and lower end covers is adjustable according to the height of the workpiece. Both the upper cover 7 and the lower cover 5 have circular pressure plate edges at their bottoms. Eight pressure plates 8 press against the pressure plate edges of the upper cover 7 and the lower cover 5, thus fixing the upper and lower covers to the rotating platform 3. Both the upper cover 7 and the lower cover 5 have annular top end face platforms, each with two handles 6. Support pads 4 are evenly distributed on the inner walls of the cylinders of both the upper cover 7 and the lower cover 5, and also on the inner walls of the top end face platforms of both the upper cover 7 and the lower cover 5. These support pads 4 can wrap around the upper, lower, and side cylindrical surfaces of the circular precision workpiece, providing support and clamping, as well as preventing bumps and scratches, thus protecting the workpiece during inspection and rotation. Multiple elliptical holes are also provided on the cylinder walls of the upper cover 7 and the lower cover 5, facilitating observation of the workpiece.

[0015] The working process of this utility model is as follows: Connect and fix the four feet 1 to the bracket 2, and fix the feet 1 to the ground. First, insert the two diagonally opposite anti-rotation fork rods 13 into the two corresponding vertical plate fork rod holes 3-2 at the diagonal of the rotating platform 3, and lock and fix the anti-rotation fork rods 13, thereby locking the rotating platform 3. Pull out the four pressure plates 8 on one side of the lower end cover 5 along the slide groove, put the lower end cover 5 on the rotating platform 3, and then push the four pressure plates 8 inward along the slide groove. The pressure plates 8 abut against the outer wall of the lower end cover 5, and then fasten them to the four fastening bolts 14 on one side of the lower end cover 5 with fasteners, so that the four pressure plates 8 press and fix the edge of the pressure plate of the lower end cover 5, thereby firmly connecting the lower end cover 5 and the rotating platform 3. Pull out the two anti-rotation fork rods 13, rotate the rotating platform 180 degrees, and then insert the two anti-rotation fork rods 13 into the two diagonally opposite vertical plate fork rod holes 3-2 to lock the anti-rotation fork rods 13 in place. At this time, hoist the workpiece onto the top of the lower end cover 5 of the rotating platform 3. The bottom and sides of the workpiece are in contact with the support pads 4 of the lower end cover 5 to prevent scratches on the workpiece. Begin inspecting the top and sides of the workpiece. After the inspection is completed, pull out the four pressure plates 8 on one side of the upper end cover 7 along the slide groove, put the workpiece on the upper end cover 7, and the support pads 4 on the inner wall of the upper end cover 7 provide support and protection for the workpiece. Then push the four pressure plates 8 inward along the slide groove and press against the outer wall of the upper end cover 7. Secure them with the four fastening bolts 14 on one side of the upper end cover 7 using fasteners. The four pressure plates 8 press and secure the edges of the pressure plates of the upper end cover 7, thus firmly connecting the upper end cover 7 and the rotating platform 3 together. Remove the anti-rotation fork rod 13, rotate the rotating platform 3 180 degrees, and then insert the two anti-rotation fork rods 13 into the corresponding vertical plate fork rod holes 3-2 to lock the anti-rotation fork rods 13. Loosen the fasteners on one side of the lower end cover 5, pull out the pressure plate 8 on one side of the lower end cover 5 along the slide groove, and remove the lower end cover 5 from the rotating platform 3. Inspect the remaining surface of the disc workpiece. After inspection, replace the lower end cover 5, push the four pressure plates 8 inward along the slide groove, and then tighten them with fasteners and four fastening bolts. Remove the two anti-rotation fork rods 13, rotate the rotating platform 180 degrees, insert the anti-rotation fork rods 13, loosen the fasteners on one side of the upper end cover 7, pull out the four pressure plates 8 on one side of the upper end cover 7 along the slide groove, remove the upper end cover 7, and take out the workpiece to complete the inspection of one complete workpiece. Then put in the next workpiece and perform the cyclic inspection process.
