AI Technical Summary
In existing technologies, when inspecting gears of different specifications and sizes, the large difference between the through hole size and the diameter of the central column causes the axis of the central column to deviate from the axis of the through hole, affecting the accuracy of the inspection. Furthermore, the contact area between the thicker part of the forged tooth and the inspection rod is small, requiring multiple operations and resulting in low inspection efficiency.
A cross-shaped abutment block is used to abut against the through hole of the gear forging, so that its axis coincides with the axis of the positioning column. The gear is rotated by a motor, and abutment arms are set on both sides of the detection rod to stabilize the abutment. Combined with a brush to clean the dirt in the tooth thickness, the accuracy and efficiency of the detection are ensured.
This improves the accuracy and efficiency of gear inspection, ensures data accuracy, and keeps the forging surface clean.

Abstract
Description
Technical Field
[0001] This invention relates to the field of forging inspection technology, specifically to a device for inspecting the shape and surface quality of forgings. Background Technology
[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power. To ensure stable transmission, the thickness of gears at different locations needs to be measured during production. Gear tooth thickness measurement is an important standard for judging the shape and quality of gears. The accuracy of gear tooth thickness measurement directly affects the technical performance of the gear pair after assembly. Precise data needs to be obtained to facilitate the later use of gears in various fields.
[0003] In response, Chinese patent application number CN202310858546.X discloses a special inspection tool for detecting the tooth thickness of planetary gear forgings, comprising: a fixed inspection platform; vertically downward support columns fixedly installed at the four corners of the bottom of the fixed inspection platform; a fixing groove opened in the middle of the left end of the fixed inspection platform; and a rectangular slot opened at the left end of the fixed inspection platform. This invention ensures that the detection rod is not blocked by iron filings at the tooth thickness, making the data detected by the detection rod more accurate, and allowing the gear forgings to be used normally in machinery. It solves the problem that newly produced planetary gears have some iron filings on them, requiring cleaning of the iron filings at the tooth thickness. If the iron filings are not cleaned properly, the detection rod stops inserted on the iron filings at the tooth thickness, preventing the detection rod from penetrating the tooth thickness and causing errors in the detected data, making it impossible to accurately detect the tooth thickness.
[0004] The device uses a limiting disc to fix the forging onto the connecting rotating block and a detection rod to abut against the tooth thickness of the forging for inspection. However, in reality, gears of different sizes have different through-hole dimensions. For forgings with larger through-hole dimensions, after being fitted onto the outside of the central column, the inner wall of the through-hole will fit against the outer wall of the central column due to the large difference between the inner diameter of the through-hole and the diameter of the central column. This causes the axis of the central column to shift from the axis of the through-hole. After fixing, the forging will shift, which will affect the accuracy of the inspection. Furthermore, the contact area between the tooth thickness of the forging and the detection rod is small, and it is easy to misalign during contact, requiring multiple operations, which makes the inspection efficiency relatively low and the actual user experience is not ideal.
[0005] Therefore, in order to solve the above problems, a device for inspecting the shape and surface quality of forgings is proposed. Summary of the Invention
[0006] The purpose of this invention is to provide a forging shape and surface quality inspection device to solve the problems mentioned in the background art. In the prior art, the device uses a limiting disc to fix the forging on a connecting rotating block and a detection rod to contact the tooth thickness of the forging for inspection. However, in reality, gears of different sizes have different through-hole dimensions. For forgings with larger through-hole dimensions, after being fitted onto the outside of the central column, the inner wall of the through-hole adheres to the outer wall of the central column due to the large difference between the inner diameter of the through-hole and the diameter of the central column. This causes the axis of the central column to shift from the axis of the through-hole. After fixing, the forging will shift, affecting the accuracy of the inspection. Furthermore, the contact area between the tooth thickness of the forging and the detection rod is small, and they are prone to misalignment during contact, requiring multiple operations, resulting in low inspection efficiency and an unsatisfactory user experience.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a forging shape and surface quality inspection device, comprising: an inspection table, wherein a guide groove is installed on the bottom surface of the upper end of the inspection table, and a gear forging is placed on the top surface of the inspection table;
[0008] The top surface of the testing station is provided with a collection groove, and a scraper is slidably installed on the inner side of the collection groove;
[0009] The top surface of the testing platform is equipped with a positioning structure, which includes a bracket. The bracket is fixedly installed on the right end of the top surface of the testing platform. A motor is fixedly installed on the bottom surface of the upper end of the testing platform. The output end of the motor is movably connected to a first pulley via a damping bearing. A rotating rod is movably installed on the right end of the top surface of the testing platform via a bearing. A second pulley is fixedly connected to the upper and lower ends of the rotating rod. A transmission belt is sleeved on the outer side of the second pulley. A third pulley is movably installed in the middle of the bracket via a bearing. A rotating column is fixedly connected to the bottom surface of the third pulley. A first cross groove is formed on the outer wall of the rotating column. A positioning column is fixedly connected to the top surface of the first pulley. A second cross groove is formed on the outer wall of the positioning column. An electric telescopic rod is fixedly installed on the top surface of the bracket. A cross rod is movably connected to the extended end of the electric telescopic rod via a bearing. A cross abutment block is integrally formed at the bottom end of the cross rod.
[0010] A detection structure is installed on the left side of the positioning structure. The detection structure includes an electric push rod, which is fixedly installed on the top left end of the detection platform. A motor is fixedly connected to the extended end of the electric push rod, and a square slotted block is fixedly connected to the output end of the motor. A connecting block is fitted on the outer side of the square slotted block, and an installation groove is opened on the surface of the connecting block. A square block is inserted into the inner side of the square slotted block. A first spring is fixedly connected to one end of the square block, and a connecting rod is fixedly connected to the other end of the square block. An abutment rod is fixedly connected to the end of the connecting rod. Two sets of abutment arms are fixedly connected to the outer wall of the connecting block. The ends of the two sets of abutment arms are rotatably connected to a sector-shaped disk. A coil spring is fixedly connected to the outer side of the sector-shaped disk. A brush is provided on the surface of the sector-shaped disk, and a sector-shaped hole is opened on the surface of the sector-shaped disk. A magnetic block is provided inside the surface of the connecting block, and a magnetic strip is provided on the inner wall of the collection groove. A scale rod is fixedly connected to the surface of the connecting block, and a detection rod is inserted inside the scale rod. A second spring is fixedly connected to the inner wall of the detection rod.
[0011] Preferably, the guide groove communicates with the inside of the collection groove, the surface of the gear forging is provided with a through hole, and the gear forging is sleeved on the outside of the positioning post through the through hole.
[0012] Preferably, the transmission belt is provided in two sets, with the ends of the two sets of transmission belts respectively fitted onto the outside of the first pulley and the third pulley.
[0013] Preferably, the first cross groove and the positioning post are aligned vertically and have the same size. The cross rod and the cross abutment block are slidably installed in the rotating post through the first cross groove. The cross rod and the cross abutment block are adapted to the first cross groove and the positioning post.
[0014] Preferably, the square slotted block is movably mounted inside the mounting groove via a bearing, with one end of the square block inserted inside the mounting groove and the other end of the square block inserted inside the square slotted block, and one end of the first spring fixedly connected to the inner wall of the square slotted block.
[0015] Preferably, the two sets of sector-shaped disks are symmetrically installed and fit together. The connecting rod passes through the two sets of sector-shaped disks through a sector-shaped hole. The diameter of the connecting rod is equal to the inner diameter of the sector-shaped hole. The connecting rod is located at the center of the connecting block. The abutting rod is located on the right side of the sector-shaped disk. The sector-shaped disk is parallel to the connecting block. One end of the coil spring is fixedly connected to the abutting arm.
[0016] Preferably, the scale rod is located on the upper side of the connecting rod, and one end of the second spring is fixedly connected to the inner wall of the scale rod.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The detection device of the present invention can abut against the through hole of the gear forging by setting a cross abutment block, so that the axis of the gear forging coincides with the axis of the positioning column, thereby ensuring that the motor can drive the gear forging to rotate around the axis, thus improving the accuracy of detection. In addition, two sets of abutment arms are set on both sides of the detection rod, which can abut against both sides of the meshing teeth of the gear forging, so as to ensure that the detection rod can be aligned with the tooth thickness of the gear forging, which facilitates the stable abutment between the detection rod and the tooth thickness of the gear forging, thereby improving the detection efficiency.
[0018] Equipped with a positioning and detection structure, the gear forging is fitted onto the outside of the positioning post through a through hole. Activating the electric telescopic rod pushes the cross rod downwards, causing it to descend into the first cross groove within the rotating post. This causes the cross rod to push the cross-shaped abutment block out from the bottom of the rotating post and insert it into the second cross groove within the positioning post. As the cross-shaped abutment block moves within the second cross groove, its bottom end inserts into the through hole of the gear forging and abuts against the inner wall of the through hole, allowing the gear forging to move outside the positioning post. Because the through hole is circular and the cross-shaped abutment block is cross-shaped, when the cross-shaped abutment block abuts against the inner wall of the circular hole, it pushes the gear forging to move outside the positioning post, aligning the axis of the gear forging with the axis of the positioning post, ensuring that the gear forging can rotate around the axis. While the line rotates, the gear forging can be fixed. Starting the motor causes the damping shaft to rotate the first pulley and positioning post. The rotation of the first pulley drives the third pulley via the transmission belt, second pulley, and rotating rod. The third pulley then drives the rotating post, which in turn drives the cross rod and cross abutment block to rotate via the first cross groove. The cross abutment block then drives the positioning post to rotate via the second cross groove, which in turn drives the gear forging to rotate, adjusting its angle. The first and second cross grooves can be kept vertically aligned. Starting the electric push rod causes the motor, connecting block, and brush to approach the gear forging. The brush then contacts the tooth thickness of the gear forging. Starting the motor again drives the connecting block, abutment arm, sector disc, and brush. The rotating brush removes dirt from the thicker areas of the gear forging teeth, keeping the surface clean. The removed dirt falls into a collection tank. Pulling the scraper moves the dirt in the collection tank, allowing it to drain through a guide groove. The connecting rod passes through a fan-shaped hole and a fan-shaped disk, with the outer wall of the connecting rod fitting against the inner wall of the fan-shaped hole. This ensures the fan-shaped disk remains fixed while the brush is in contact with the gear forging surface, providing support and maintaining sufficient rigidity for improved cleaning. As the electric push rod continues to operate, the abutment rod contacts the surface of the gear forging, and the abutment rod reacts against the connecting rod, pushing the square block out of the mounting slot until it is fully inserted into the slot. Inside the sleeve block, the connection between the square slotted sleeve block and the connecting block can be released. At this point, the continued operation of the motor will not be able to drive the connecting block to rotate, and the connecting block will stop. It will remain fixed under the magnetic attraction of the magnetic block and magnetic strip. At this time, the two sets of sector-shaped disks on the two sets of abutment arms will be symmetrically located on both sides of the tooth thickness of the gear forging. At the same time, the connecting rod moves away from the inside of the sector-shaped hole, thus releasing the restriction on the sector-shaped disks. As the electric push rod continues to run, the gear forging pushes the brush and the sector-shaped disks, causing the sector-shaped disks to rotate on the abutment arms and deform the coil spring. Therefore, the two sets of sector-shaped disks are located on both sides of the tooth thickness of the gear forging, and the ends of the abutment arms will abut against both sides of the tooth thickness of the gear forging. The gear forging then drives the positioning column and the first pulley to rotate at the output end of the motor through the damping shaft.By adjusting the angle of the gear forging, the detection rod is aligned with the center of the gear forging's tooth thickness. When the detection rod is in contact with the tooth thickness of the gear forging, the gear forging pushes the detection rod to slide inside the scale rod. The detection rod compresses the second spring. By observing the position of the detection rod relative to the scale on the scale rod, accurate data can be measured. Attached Figure Description

A cross rod 213 is movably connected to the extended end of the electric telescopic rod 212 through a bearing. A cross abutment block 214 is integrally formed at the bottom end of the cross rod 213.
[0037] A detection structure 3 is installed on the left side of the positioning structure 2. The detection structure 3 includes an electric push rod 31, which is fixedly installed on the top left end of the detection table 1. A motor 32 is fixedly connected to the extended end of the electric push rod 31. A square slotted block 35 is fixedly connected to the output end of the motor 32. A connecting block 33 is fitted on the outer side of the square slotted block 35. An installation groove 34 is opened on the surface of the connecting block 33. A square block 36 is inserted into the inner side of the square slotted block 35. A first spring 37 is fixedly connected to one end of the square block 36. A connecting rod 38 is fixedly connected to the other end of the square block 36. An abutment rod 39 is fixedly connected to the end of the connecting rod 38. Two sets of abutment arms 310 are fixedly connected to the outer wall of the connecting block 33. A sector-shaped disk 311 is rotatably connected to the end of each of the two sets of abutment arms 310. A coil spring 312 is fixedly connected to the outer side of the sector-shaped disk 311. A brush 313 is provided on the surface of the sector-shaped disk 311. The surface of the disc 311 has a fan-shaped hole 314. The surface of the connecting block 33 has a magnetic block 315 inside. The inner wall of the collecting groove 12 has a magnetic strip 316. The surface of the connecting block 33 is fixedly connected to a scale rod 317. A detection rod 318 is inserted inside the scale rod 317. A second spring 319 is fixedly connected to the inner wall of the detection rod 318. The cross abutment block 214 can abut in the through hole of the gear forging 14, so that the axis of the gear forging 14 coincides with the axis of the positioning column 210, so that the motor 22 can drive the gear forging 14 to rotate around the axis, thereby improving the accuracy of detection. Two sets of abutment arms 310 are provided on both sides of the detection rod 318. The abutment arms 310 can abut on both sides of the meshing teeth of the gear forging 14, so that the detection rod 318 can be aligned with the tooth thickness of the gear forging 14, which facilitates the stable abutment of the detection rod 318 with the tooth thickness of the gear forging 14 and improves the detection efficiency.
[0038] Furthermore, the guide groove 11 is connected to the inside of the collection groove 12, and the surface of the gear forging 14 is provided with a through hole. The gear forging 14 is sleeved on the outside of the positioning post 210 through the through hole. The dirt in the collection groove 12 can be discharged through the guide groove 11, and the rotation of the positioning post 210 can drive the gear forging 14 to rotate.
[0039] Furthermore, two sets of transmission belts 26 are provided. The ends of the two sets of transmission belts 26 are respectively sleeved on the outside of the first pulley 23 and the third pulley 27. The rotation of the first pulley 23 can drive the second pulley 25, the rotating rod 24 and the third pulley 27 to rotate through the transmission belts 26, so as to ensure that the positioning post 210 and the rotating post 28 remain aligned, and facilitate the movement of the cross rod 213 and the cross abutment block 214 between the first cross groove 29 and the second cross groove 211.
[0040] Furthermore, the first cross groove 29 and the positioning post 210 are aligned vertically and have the same dimensions. The cross rod 213 and the cross abutment block 214 are both slidably installed in the rotating post 28 through the first cross groove 29. The cross rod 213 and the cross abutment block 214 are adapted to the first cross groove 29 and the positioning post 210. The cross rod 213 and the cross abutment block 214 can move in the rotating post 28 through the first cross groove 29 and can move downward in the positioning post 210 through the second cross groove 211.
[0041] Furthermore, the square slotted block 35 is movably mounted inside the mounting groove 34 via a bearing. One end of the square block 36 is inserted inside the mounting groove 34, and the other end of the square block 36 is inserted inside the square slotted block 35. One end of the first spring 37 is fixedly connected to the inner wall of the square slotted block 35. The connecting block 33 can rotate outside the square slotted block 35. The square block 36 provides a connection for the fixing between the connecting block 33 and the square slotted block 35, so that the connecting block 33 can rotate under the action of the motor 32. The first spring 37 provides power for one end of the square block 36 to be pushed out from inside the square slotted block 35 and inserted into the mounting groove 34.
[0042] Furthermore, the two sets of sector-shaped disks 311 are symmetrically installed and fit together. The connecting rod 38 passes through the two sets of sector-shaped disks 311 via the sector-shaped hole 314. The diameter of the connecting rod 38 is equal to the inner diameter of the sector-shaped hole 314. The connecting rod 38 is located at the center of the connecting block 33. The abutting rod 39 is located on the right side of the sector-shaped disk 311. The sector-shaped disk 311 is parallel to the connecting block 33. One end of the coil spring 312 is fixedly connected to the abutting arm 310. The connecting rod 38 fits against the inner wall of the sector-shaped hole 314, which allows the two sets of sector-shaped disks 311 to remain in a fitted state and parallel to the connecting block 33, so that the sector-shaped disk 311 maintains a fixed angle on the abutting arm 310, providing a bearing for the sector-shaped disk 311 to brush the gear forging 14. The abutting rod 39 can fit against the gear forging 14 when the abutting arm 310 is close to the gear forging 14, so as to push the connecting rod 38 out from the inside of the abutting arm 310.
[0043] Furthermore, the scale rod 317 is located on the upper side of the connecting rod 38, and one end of the second spring 319 is fixedly connected to the inner wall of the scale rod 317. When the detection rod 318 is in contact with the tooth thickness of the gear forging 14, the contact position has been cleaned by the coil spring 312, which can maintain the detection effect. The second spring 319 provides power for the detection rod 318 to reset on the scale rod 317.
[0044] Working principle: During testing, the gear forging 14 is sleeved on the outside of the positioning post 210 through the through hole. The electric telescopic rod 212 is activated, pushing the cross rod 213 downwards. This causes the cross rod 213 to descend in the first cross groove 29 within the rotating post 28. The cross rod 213 then drives the cross abutment block 214 out from the bottom of the rotating post 28 and inserts it downwards into the second cross groove 211 within the positioning post 210. As the cross abutment block 214 moves inside the second cross groove 211... Its bottom end is inserted into the through hole of the gear forging 14 and abuts against the inner wall of the through hole, so that the gear forging 14 can move outside the positioning post 210. Since the through hole is circular and the cross abutment block 214 is cross-shaped, when the cross abutment block 214 abuts against the inner wall of the circular hole, it will push the gear forging 14 to move outside the positioning post 210, so that the axis of the gear forging 14 coincides with the axis of the positioning post 210, ensuring that the gear forging 14 can rotate around the axis while fixing the gear forging 14.
[0045] When the motor 22 is started, the damping shaft drives the first pulley 23 and the positioning post 210 to rotate. The rotation of the first pulley 23 can drive the third pulley 27 to rotate through the transmission belt 26, the second pulley 25 and the rotating rod 24. The third pulley 27 drives the rotating post 28 to rotate. The rotating post 28 drives the cross rod 213 and the cross abutment block 214 to rotate through the first cross groove 29. The cross abutment block 214 drives the positioning post 210 to rotate through the second cross groove 211. The positioning post 210 drives the gear forging 14 to rotate, so as to adjust the angle of the gear forging 14. The first cross groove 29 and the second cross groove 211 can be kept vertically aligned.
[0046] When the electric push rod 31 is activated, it drives the motor 32, connecting block 33, and brush 313 to approach the gear forging 14. The brush 313 then comes into contact with the tooth thickness of the gear forging 14. Activating the motor 32 causes the connecting block 33, abutment arm 310, sector disc 311, and brush 313 to rotate. The rotating brush 313 removes dirt from the tooth thickness of the gear forging 14, keeping the surface of the gear forging 14 clean. The removed dirt falls into the collection tank 12. By pulling the scraper 13, the dirt in the collection tank 12 can be scraped away, making it... The material is discharged through the guide groove 11, and the connecting rod 38 passes through the fan-shaped hole 314 through the fan-shaped disk 311. Simultaneously, the outer wall of the connecting rod 38 fits against the inner wall of the fan-shaped hole 314. Therefore, when the brush 313 is in contact with the surface of the gear forging 14, the fan-shaped disk 311 remains fixed to provide support for the brush 313, allowing the brush 313 to maintain sufficient rigidity and improve the cleaning effect. As the electric push rod 31 continues to operate, the abutment rod 39 fits against the surface of the gear forging 14, and the abutment rod 39 reacts to the connecting rod 38, which in turn pushes the square block 36, causing the square block 36 to... Pushed out from the inside of the mounting slot 34, the square block 36 is fully inserted into the square slot sleeve block 35, releasing the connection between the square slot sleeve block 35 and the connecting block 33. At this point, the continued operation of the motor 32 can no longer drive the connecting block 33 to rotate, and the connecting block 33 will stop and remain fixed under the magnetic attraction of the magnetic block 315 and the magnetic strip 316. At this time, the two sets of sector disks 311 on the two sets of abutment arms 310 will be symmetrically located on both sides of the tooth thickness of the gear forging 14. At the same time, the connecting rod 38 moves away from the inside of the sector hole 314, thus releasing the restriction on the sector disk 311. As push rod 31 continues to operate, gear forging 14 pushes brush 313 and sector disk 311, causing sector disk 311 to rotate on abutment arm 310 and pull coil spring 312 to deform. Therefore, the two sets of sector disks 311 are located on both sides of the tooth thickness of gear forging 14, and the end of abutment arm 310 will abut on both sides of the tooth thickness of gear forging 14. Gear forging 14 then drives positioning column 210 and first pulley 23 to rotate at the output end of motor 22 through damping shaft to adjust the angle of gear forging 14 so that detection rod 318 is aligned with the middle of tooth thickness of gear forging 14.
[0047] When the detection rod 318 is in contact with the tooth thickness of the gear forging 14, the gear forging 14 will push the detection rod 318 to slide inside the scale rod 317. The detection rod 318 can compress the second spring 319. By observing the position of the detection rod 318 and the scale on the scale rod 317, accurate data can be measured.
