Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing equipment for forgings, specifically a flipping inspection device for multi-angle flaw detection or dimensional inspection of large forgings. Background Technology

[0002] In the process of forging production quality inspection, it is necessary to conduct multi-faceted inspection of the surface and internal defects of the forgings; existing flipping inspection devices generally have the following technical defects:

[0003] 1. Poor clamping adaptability: Traditional clamps use a rigid positioning structure, which cannot effectively adapt to the curved contour of irregular forgings. This can lead to local stress concentration or insecure fixation during clamping, and the forgings may shake or even fall off during the flipping process.

[0004] 2. Low flipping positioning accuracy: Most equipment relies on motor brakes or pin-type limit switches. The former has inertial displacement that causes angular deviation (above ±2°), while the latter requires repeated manual operation of the hole, making it difficult to achieve fast and accurate locking of standard angles such as 90° and 180°.

[0005] 3. Limited driving mode: Manual flipping devices are inefficient (single-piece operation time ≥ 15 minutes), while pure electric equipment lacks fine-tuning capabilities and cannot meet the fine inspection requirements of small-batch customized forgings. Utility Model Content

[0006] To overcome the problems of unstable clamping of irregular forgings, poor flipping and positioning accuracy, and single driving mode, this utility model provides a forging flipping and inspection device. Through the synergy of symmetrical adjustable clamping components and indexing support components, combined with a dual-mode driving mechanism, it achieves three-dimensional stable clamping of irregular forgings, ±0.5° precise flipping and positioning, and efficient and flexible inspection operations.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a forging turning inspection device, including a frame; a pair of clamping components symmetrically arranged on the upper part of the frame for clamping and fixing forgings; a supporting component connected to the clamping components for driving the clamping components and forgings to turn; the clamping components include a frame, a support plate, a pressure block and a top pin, the inner side of the frame is provided with multiple spaced support plates for supporting forgings, the upper part of the frame is provided with multiple adjustable pressure blocks for pressing down and fixing forgings, and the inner side of the frame is symmetrically provided with top pins for abutting against the side wall of forgings; the supporting component includes a shaft horizontally placed on the frame, a chuck connecting the shaft and the frame, and a valve pin for limiting the chuck, the chuck is provided with multiple U-shaped grooves around its periphery, and the valve pin is adapted to the U-shaped grooves to achieve indexing locking.

[0008] In the aforementioned forging inspection device, a T-shaped support rod is connected to the upper part of the pressure block. The T-shaped support rod passes through the pressure block and is slidably connected to the frame. A handwheel is screwed to the top of the T-shaped support rod to drive the pressure block to move down and lock it.

[0009] The forging turning and inspection device described above has a slide groove on the upper part of the frame for the T-shaped support rod to slide back and forth.

[0010] In the forging turning inspection device described above, a spring is sleeved on the upper part of the top pin, and the two ends of the spring abut against the top pin and the inner wall of the frame respectively to achieve elastic pre-tightening.

[0011] In the aforementioned forging turning and inspection device, the valve pin is connected to the frame via a bearing seat, and the upper part of the bearing seat is provided with a bolt that locks the axial position of the valve pin.

[0012] In the aforementioned forging overturning inspection device, one end of the shaft is connected to a reducer, which is configured as a dual-mode input structure that can be switched to motor drive or handwheel drive.

[0013] The aforementioned forging overturning inspection device uses a worm gear reducer as its speed reducer.

[0014] The forging turning and inspection device described above has a worm gear reducer with a self-locking function.

[0015] In the forging turning and inspection device described above, the pair of clamping components are arranged in a mirror-symmetric manner with respect to the center line of the frame.

[0016] In the aforementioned forging turning inspection device, the U-shaped grooves are evenly distributed around the circumference of the chuck and there are no fewer than four of them.

[0017] The beneficial effects of this utility model are:

[0018] 1. Multi-angle stable clamping: The support plate and the pressure block form a vertical bearing surface, and the top pin provides horizontal elastic pre-tightening to achieve three-dimensional constraint of the forging, adapting to irregular contours such as crankshafts and flanges, and avoiding flipping and shaking;

[0019] 2. Precise indexing and positioning: The mechanical interlock of the valve pin inserting into the U-shaped groove, combined with the axial locking of the bolt, ensures that the repeatability of standard angles such as 90° and 180° is ≤±0.5°;

[0020] 3. Flexible drive adaptation: The dual-mode input of motor / handwheel combined with worm gear self-locking improves automatic flipping efficiency by 60% (up to 5 pieces / hour), and the manual mode supports 0.1° fine adjustment;

[0021] 4. Enhanced operational safety: The T-shaped strut slide adjustment enables rapid alignment of the pressure block, and the worm gear self-locking mechanism eliminates the risk of reverse rotation due to its own weight, ensuring safety during high-altitude operations.

[0029] This embodiment describes in detail a forging turnover inspection device, such as... Figure 1-5 As shown, the forging turning inspection device mainly includes a frame 1 for supporting the forging off the ground. The upper part of the frame 1 is symmetrically arranged with clamping components 2 for clamping and fixing the forging. A support component 3 is arranged on one side of the clamping components 2 to support its rotation. The clamping components 2 are arranged in a mirror symmetrical manner. This design facilitates the all-round inspection of the forging.

[0030] The clamping assembly 2 includes a frame 21, a support plate 22, pressure blocks 23, and a top pin 24. The frame 21 is located on the upper part of the machine frame 1 and does not directly contact the machine frame 1, providing an installation base and support structure for other components. Support plates 22 are arranged at intervals along the length of the inner side of the frame 21. These support plates 22 are used to horizontally support the forging. When the forging is placed on the inspection device, the bottom of the forging rests smoothly on the support plate 22, providing initial positioning and support. Pressure blocks 23 are evenly and at intervals along the length of the upper part of the frame 21. The pressure blocks 23 are used to press down and fix the forging. A T-shaped support rod 25 is arranged on the upper part of the pressure block 23, penetrating its surface and slidingly connected to the frame 21. A handwheel 26 is screwed to the top of the T-shaped support rod 25. When installing the forging, first place the forging on the support plate 22, then adjust the position of the pressure block 23 to align it with the part of the forging that needs to be clamped, and then turn the handwheel 26. The handwheel 26 gradually moves downward. The handwheel 26 abuts against the upper surface of the pressure block 23. As the handwheel 26 continues to rotate, it exerts downward pressure on the pressure block 23, thereby achieving the locking and adjustment operation of the pressure block 23 and firmly fixing the forging to the support plate 22. The upper part of the frame 21 is also provided with a slide groove for the T-shaped support rod 25 to reciprocate and slide. This allows the T-shaped support rod 25 to move flexibly in the slide groove according to the size and shape of the forging, thereby adjusting the position of the pressure block 23 to meet the fixing requirements of forgings of different specifications. The top pin 24 is symmetrically arranged on the inner side of the frame 21 and is used to abut against the side wall of the forging. In order to ensure that the top pin 24 abuts against the side wall of the forging, a spring 27 is sleeved on the upper part of the top pin 24 to abut against the inner wall of the frame 21. When the forging is placed on the support plate 22 and the position is adjusted, the top pin 24, under the action of the spring 27, always applies a stable thrust to the side wall of the forging, so that the forging remains stable in the horizontal direction and prevents shaking or displacement during the flipping inspection.

[0031] The support assembly 3 includes a shaft 31, a chuck 32, and a valve pin 33. The shaft 31 is horizontally positioned on the upper part of the frame 1 and connected to the frame 1 via a bearing seat. The bearing seat supports the shaft 31 and reduces its rotational friction, allowing the shaft 31 to rotate smoothly. One end of the shaft 31 is bolted to the chuck 32, which is also bolted to the frame 21. Thus, the rotation of the shaft 31 drives the chuck 32 and the frame 21 to rotate together, thereby achieving the flipping of the forging. The chuck 32 has inwardly recessed U-shaped grooves 34 evenly formed around its circumference. These U-shaped grooves 34 provide a structural basis for subsequent clamping and limiting operations. A valve pin 33 is arranged on one side. The valve pin 33 is also connected to the frame 1 through the bearing seat. One end of the valve pin 33 is adapted to the U-shaped groove 34. When the forging needs to be positioned for inspection, the valve pin 33 is inserted into the corresponding U-shaped groove 34 to perform a locking and limiting operation on the chuck 32, so that the chuck 32, the frame 21 and the forging stop rotating and are maintained at a specific inspection angle. The valve pin 33 is axially locked and fixed by the bolts on the upper part of the bearing seat. After the valve pin 33 is inserted into the U-shaped groove 34, the bolts on the upper part of the bearing seat are tightened to fix the valve pin 33 in the current position, preventing the valve pin 33 from accidentally coming out during the inspection and ensuring the stability of the forging positioning.

[0032] One of the supporting components 3 is keyed to a reducer 4. The reducer 4 is bolted to the upper part of the frame 1. A motor or handwheel 26 can be connected to one side of the reducer 4 for driving operation. When the motor is connected, the motor rotates at high speed. After the reducer 4 reduces speed and increases torque, it outputs a suitable speed and torque, driving the shaft 31 to rotate, thereby realizing the automatic flipping of the forging. This driving method is suitable for large-scale production inspection, with high efficiency and convenient operation. When the handwheel 26 is connected, the operator can manually rotate the handwheel 26 to drive the shaft 31 to rotate, realizing the manual flipping of the forging. The manual driving method is suitable for some occasions where the requirements for flipping speed and angle are not strict, or where fine adjustment and inspection are required. In this embodiment, the reducer 4 is preferably a worm gear reducer 4. The worm gear reducer 4 has a self-locking function. When the motor or handwheel 26 stops rotating, the transmission structure of the worm gear can prevent the shaft 31 from reversing due to the weight of the forging and other factors, further ensuring the stability and safety of the forging during the inspection process.
