Description

Technical Field

[0001] This utility model relates to the field of forging inspection technology, and in particular to a positioning support device for detecting surface defects in forgings. Background Technology

[0002] Forgings are prone to surface cracks, pits and other defects during the manufacturing process. Traditional inspection mainly relies on manual handheld equipment or fixed support devices.

[0003] A search revealed Chinese patent CN219369738U, which discloses a forging surface inspection device. The device includes a transport mechanism fixedly mounted on the top of a support mechanism, an inspection mechanism fixedly mounted on the top of the support mechanism, and a rotating mechanism fixedly mounted on the top of the support mechanism. The device uses two electrically operated telescopic rods that extend and retract in opposite directions to clamp the forging with two clamping plates. A cylinder drives two moving plates and components mounted on their surface walls to move in tandem. A motor then drives the two electrically operated telescopic rods to rotate within two bearings.

[0004] However, the device still has the following problems: the device uses a cylinder set on one side to drive one of the moving plates to rise, and then the moving plate drives the clamping plate to rise. Then, one of the clamping plates pulls the other clamping plate to rise through the forging. Therefore, during the lifting process of the forging, the forging is subjected to uneven force, which poses a risk of deformation and makes it difficult to effectively improve the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning support device for detecting surface defects in forgings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning support device for detecting surface defects in forgings includes a base, two pairs of guide sleeves fixedly connected to the top two sides of the base, a guide rod slidably connected to the inner wall of each guide sleeve, and a support plate fixedly connected to the top of each pair of guide rods. The device also includes a positioning component and a driving component disposed above the base.

[0008] The positioning assembly includes a pair of threaded sleeves rotatably connected to the top sides of the base near the guide sleeves. Each threaded sleeve has a threaded rod threaded to its top end, and the top end of each threaded rod is fixedly connected to the bottom end of the support plate. A drive wheel is fixedly connected to one end of the outer peripheral wall of each threaded sleeve. A belt is fitted onto one end of each pair of drive wheels to form a transmission connection. The belt synchronously drives the double threaded sleeves, ensuring synchronized movement of the support plates on both sides and avoiding uneven loading.

[0009] Each of the support plates has a fixed base fixedly connected to one side of its top. Each fixed base has a mounting plate rotatably connected to one end. One end of one mounting plate is fixedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a worm gear. Near the transmission rod, a pair of fixed brackets are fixedly connected to the top of one of the support plates. One end of each pair of fixed brackets is rotatably connected to a worm gear that meshes with the worm gear, and the helix angle between the worm gear and the worm gear is less than the friction angle. The self-locking design of the worm gear and worm gear fixes the angle of the mounting plate, preventing displacement during testing.

[0010] Preferably, an electric telescopic rod is fixedly connected to the other end of each mounting plate, and a clamping plate is fixedly connected to the extension end of each electric telescopic rod.

[0011] Preferably, a lamp holder is fixedly connected to the top of another support plate near the mounting base, and a lamp head is mounted on one end of the lamp holder. The lamp head provides an adjustable light source, eliminates inspection shadows, and enhances the contrast of surface defects.

[0012] Preferably, the drive assembly includes a motor fixedly connected to the top of the base near the threaded sleeve, and the output shaft of the motor is fixedly connected to a bevel gear.

[0013] Preferably, one of the threaded sleeves has a bevel gear two fixedly connected to the other end of its outer peripheral wall, which meshes with bevel gear one. The threaded sleeve is driven to rotate by the interaction between motor one, bevel gear one, and bevel gear two.

[0014] Preferably, a second motor is fixedly connected to the top of one of the support plates near the fixed frame, and the output shaft of the second motor is fixedly connected to one end of the worm gear.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Through the cooperation between the belt and the drive wheel, a pair of threaded sleeves rotate synchronously, thereby raising a pair of support plates synchronously. This avoids uneven force on the forgings during the lifting process. At the same time, the self-locking effect between the worm gear and the worm prevents external forces from causing the forgings to deflect at an angle, which facilitates subsequent processing of surface defects on the forgings and effectively improves the practicality of the device.

[0017] 2. Through the cooperation between the motor, the worm gear, and the worm, the transmission rod can be driven to rotate slowly and at a uniform speed, which facilitates the comprehensive detection of surface defects in forgings and avoids missed detections. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figure 1-4 A positioning support device for detecting surface defects in forgings includes a base 1, which is made of high-strength alloy material to enhance the overall structural strength of the device. Two pairs of guide sleeves 2 are fixedly connected to the top two sides of the base 1. A guide rod 3 is slidably connected to the inner wall of each guide sleeve 2. A support plate 4 is fixedly connected to the top of each pair of guide rods 3. The movement direction of the support plate 4 is limited by the mutual cooperation between the guide rods 3 and the guide sleeves 2. The device also includes a positioning component and a driving component disposed above the base 1.

[0025] like Figures 2-4As shown, in one embodiment, the positioning assembly includes a pair of threaded sleeves 5 rotatably connected to the top sides of the base 1 near the guide sleeves 2. Each threaded sleeve 5 has a threaded rod 6 threadedly connected to its top end, and the top end of each threaded rod 6 is fixedly connected to the bottom end of the support plate 4. Through the interaction between the threaded sleeves 5 and the threaded rods 6, the support plate 4 moves up and down. A transmission wheel 10 is fixedly connected to one end of the outer peripheral wall of each threaded sleeve 5. A belt 11 is fitted onto one end of each pair of transmission wheels 10 to form a transmission connection. Through the interaction between the transmission wheels 10 and the belt 11, the pair of threaded sleeves 5 rotate synchronously, thereby driving the pair of support plates 4 to rise and fall synchronously. A threaded rod 6 is fixedly connected to one side of the top of each support plate 4. Each fixed base 12 has a mounting plate 13 rotatably connected to one end. One end of one mounting plate 13 is fixedly connected to a transmission rod 16, which drives the mounting plate 13 to rotate. One end of the transmission rod 16 is fixedly connected to a worm gear 17. A pair of fixed brackets 18 are fixedly connected to the top of one of the support plates 4 near the transmission rod 16. One end of the pair of fixed brackets 18 is rotatably connected to a worm 19 that meshes with the worm gear 17. Through the cooperation between the worm gear 17 and the worm 19, the transmission rod 16 is driven to rotate. The helix angle between the worm 19 and the worm gear 17 is less than the friction angle. Through the self-locking effect between the worm 19 and the worm gear 17, the rotation of the mounting plate 13 is prevented by external forces.

[0026] like Figure 1 and Figure 2 As shown, in one embodiment, each mounting plate 13 is fixedly connected to an electric telescopic rod 14 at its other end, and each electric telescopic rod 14 is fixedly connected to a clamping plate 15 at its extended end. The forging is clamped and fixed by the mutual cooperation between the pair of clamping plates 15. A lamp holder 21 is fixedly connected to the top of another support plate 4 near the fixing seat 12. A lamp head 22 is installed at one end of the lamp holder 21. The brightness of the forging surface is enhanced by the mutual cooperation between the lamp head 22 and the lamp holder 21, which facilitates the detection of defects on the surface of the forging.

[0027] like Figure 3 and Figure 4 As shown, in one embodiment, the driving assembly includes a motor 7 fixedly connected to the top of the base 1 near the threaded sleeve 5. The output shaft of the motor 7 is fixedly connected to a bevel gear 8. The other end of the outer peripheral wall of one of the threaded sleeves 5 is fixedly connected to a bevel gear 9 that meshes with the bevel gear 8. Through the mutual cooperation between the motor 7, the bevel gear 8, and the bevel gear 9, one of the threaded sleeves 5 is driven to rotate. A motor 20 is fixedly connected to the top of one of the support plates 4 near the fixing frame 18. The output shaft of the motor 20 is fixedly connected to one end of the worm gear 19. The motor 20 serves to start the rotation of the worm gear 19.

[0028] Working principle: In use, firstly, a pair of electric telescopic rods 14 are activated, which drive a pair of clamping plates 15 to clamp and fix the forging. Then, motor 7 is activated, and through the interaction between motor 7, bevel gear 8, and bevel gear 9, one of the threaded sleeves 5 is driven to rotate. Then, through the interaction between belt 11 and transmission wheel 10, the two threaded sleeves 5 are driven to rotate synchronously. Then, through the interaction between threaded sleeve 5 and threaded rod 6, the support plate 4 is lifted to a specified height, so that the forging is at a specified height. Then, the surface of the forging is inspected by the detection device. At the same time, motor 20 is activated, which drives worm gear 19 to rotate. Then, through the interaction between worm gear 19 and worm wheel 17, the transmission rod 16 is driven to rotate slowly and uniformly, which facilitates comprehensive inspection of surface defects of the forging. When a surface defect of the forging is detected, motor 20 is turned off. Through the self-locking effect between worm wheel 17 and worm gear 19, the angle of the forging is prevented from deflecting due to external force, which facilitates subsequent processing of surface defects of the forging.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
