Description

Technical Field

[0001] This invention relates to the field of gear machining accuracy testing technology, specifically to an adjustment mechanism for gear accuracy testing. Background Technology

[0002] Gears are one of the key components in industry, and have always accompanied industrial development. The invention of gears has brought great changes to our lives. Gears are widely used, and at the same time, higher requirements are placed on machining accuracy. Gear machining accuracy testing technology can be used to evaluate gear accuracy. The corresponding testing equipment includes CNC gear measuring centers, gear double-sided meshing comprehensive inspection instruments, gear radial runout testers, gear tooth profile and tooth direction testers, common normal micrometers, chordal tooth height vernier calipers, tooth thickness micrometers, etc.

[0003] Gears, when used at high speeds for extended periods, are prone to fatigue damage. Furthermore, during meshing and rotation, the immense power and resistance exerted on the gears can easily lead to wear or deformation. Currently, gear precision testing requires manual loading of the gears onto the testing device. However, manual loading is inherently uncontrollable, and human error may cause collisions between the tested part and the testing device, damaging not only the tested part but also, in some cases, the testing mechanism itself, significantly reducing the accuracy of the test.

[0004] Therefore, we propose an adjustment mechanism for gear accuracy testing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustment mechanism for gear precision testing, which automates the loading, testing, and unloading processes during gear precision testing, thereby improving the accuracy and efficiency of the testing.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an adjustment mechanism for gear precision detection, comprising a fixed base frame, wherein a feeding platform and a picking platform are respectively provided on both sides of the top of the fixed base frame, an adjustment frame is also provided on the top of the fixed base frame and between the feeding platform and the picking platform, and a mounting bracket is also provided in the middle of the top of the fixed base frame and directly above the adjustment bracket, and an adjustment component is provided inside the mounting bracket;

[0007] The adjustment component includes a mounting frame, which is movably positioned below the mounting bracket. The mounting bracket has four first servo electric cylinders inside, and the drive ends of the four first servo electric cylinders are respectively connected to both sides of the mounting frame. The bottom of the mounting frame is provided with sliding grooves around its four sides, and movable blocks are slidably arranged inside the four sliding grooves. The bottom of the movable blocks is provided with detection blocks through miniature electric cylinders.

[0008] The detection block is trapezoidal in shape, and each of the three inner walls of the detection block is provided with a fixing block. Several detection rods are movably arranged inside the fixing block, and spring plates are sleeved on the surface of each detection rod. A pressure sensor corresponding to the number of detection rods is provided on one side of the inner wall of the fixing block, and the force-bearing end of each pressure sensor is in contact with one end of each detection rod.

[0009] Preferably, a miniature electric cylinder is provided at the bottom of the mounting bracket and on one side of each of the four movable blocks, and a marker block is provided at the drive end of each of the four miniature electric cylinders.

[0010] Preferably, the mounting bracket is provided with a drive block inside, and the drive block is provided with two first lead screws in a cross-shaped rotation. The two ends of the two first lead screws are respectively connected to the internal threads of the four movable blocks, and the two sides of the surface of the two first lead screws are respectively provided with external threads with opposite directions of rotation.

[0011] Preferably, the two first lead screws are arranged vertically inside the drive block, and one end of each of the two first lead screws is driven by a motor.

[0012] Preferably, the top of the mounting bracket is bolted to a top plate, and the top of the mounting support is bolted to a maintenance cover.

[0013] Preferably, both the feeding platform and the unloading platform are provided with a feeding assembly on their front sides. The feeding assembly includes a movable frame, and a second lead screw is rotatably provided inside the movable frame. Clamping frames are threaded on both sides of the surface of the second lead screw, and the two clamping frames are slidably located on both sides inside the movable frame.

[0014] Preferably, the second lead screw has external threads with opposite directions on both sides of its surface, and one end of the second lead screw is driven by a motor, with an electric slide provided on the front of the feeding platform and the picking platform.

[0015] Preferably, the bottom of the fixed base frame is provided with a mounting plate, and the top of the mounting plate is provided with a second servo electric cylinder on all four sides. The drive ends of the four second servo electric cylinders are all connected to the bottom of the adjustment frame. The adjustment frame is rotatably provided with a rotating frame inside, and the bottom of the rotating frame is provided with a gear ring. The bottom of the rotating frame is provided with a steering motor, and the output end of the steering motor is provided with a drive gear that meshes with the gear ring.

[0016] Preferably, a third servo electric cylinder is also provided around the bottom of the mounting frame, and each of the drive ends of the third servo electric cylinder is provided with a positioning plate.

[0017] Preferably, the adjustment mechanism for gear accuracy detection is used as follows:

[0018] Step 1: Place the gear to be tested on the feeding platform. Use the second lead screw to rotate and drive the two clamping frames to clamp the two sides of the gear to be tested. Drive the adjustment frame downward through the drive end of the second servo electric cylinder. At this time, the gear to be tested is sent to the top of the adjustment frame through the electric slide table and placed on the top of the adjustment frame.

[0019] Step 2: The drive end of the first servo cylinder pushes the mounting bracket downwards, so that the four positioning plates at the bottom of the mounting bracket are above the adjustment bracket. Then, the drive shaft of the third servo cylinder pushes the positioning plates closer to the detection gear, adjusting the position of the detection gear on the rotating bracket to the center position.

[0020] Step 3: Select the corresponding detection blocks in advance according to the tooth specifications of the detection gear. Then, adjust the position of the four detection blocks by controlling the two first lead screws so that the four detection blocks are distributed at equal angles about the central axis of the detection gear.

[0021] Step 4: After adjusting the position of the detection gear on the rotating frame to the center position, the miniature electric cylinder pushes the detection block downwards. The detection block is used to perform precision detection on the teeth of the detection gear. Then, the output shaft of the steering motor drives the gear ring to rotate through the drive gear, adjusting the direction of the rotating frame, and then adjusting the orientation of the detection teeth of the detection gear on the rotating frame. The continuous detection processing of the teeth of the detection gear is achieved through four detection blocks.

[0022] Step 5: Apply pressure to the force-receiving end of the pressure sensor using one end of the detection rod, and collect the pressure data of the pressure sensor in real time. Make the detection end of the detection rod contact the tooth surface of the detection gear. When the teeth of the detection gear are worn, the detection end of the detection rod extends outward. At this time, the pressure on the force-receiving end of the pressure sensor decreases, so the pressure value of the pressure sensor decreases. When the pressure value of the pressure sensor is less than the maximum wear amount, use the drive end of the micro electric cylinder to drive the marking block to mark the tooth position of the detection gear on the upper surface of the gear.

[0023] Step Six: After completing the precision inspection of the gear, the drive end of the second servo cylinder drives the adjustment frame to move downward. Then, the two clamping frames on the front of the pick-up table move to the top of the adjustment frame. The drive end of the second servo cylinder drives the adjustment frame to move upward. The two clamping frames clamp the two sides of the gear and send the inspected gear to the pick-up table for delivery, thus completing the automated precision inspection of the gear.

[0024] This invention provides an adjustment mechanism for gear accuracy testing. Compared with the prior art, it has the following advantages:

[0025] By setting up a feeding platform and a picking platform on both sides of the top of the fixed base frame, and setting an adjustment frame and mounting bracket between the feeding platform and the picking platform, the feeding assembly automatically transports the detection gear on the feeding platform, adjustment frame, and picking platform. Sponge blocks on one side of the two clamping frames are used to fit the circumference of the gear, protecting the gear surface from damage during transportation and improving the stability of the gear during transportation, preventing the gear from slipping between the two clamping frames. By setting a rotating frame inside the adjustment frame, and installing an electromagnet inside the rotating frame, the detection gear can be limited on the rotating frame. By controlling the rotation of the rotating frame, the orientation of the detection gear can be flexibly adjusted. In conjunction with the four detection blocks set in the adjustment assembly, each tooth of the detection gear is simultaneously inspected for precision, significantly improving the accuracy and efficiency of gear precision inspection.

[0026] By incorporating a detection rod within the detection block, one end of which engages with a pressure sensor, pressure is applied to the force-bearing end of the pressure sensor. The pressure data from the sensor is collected in real time. The detection end of the rod contacts the tooth surface of the gear being tested. As the gear teeth wear down, the detection end of the rod extends outwards, reducing the pressure on the force-bearing end of the pressure sensor and thus lowering its pressure reading. When the pressure reading falls below the maximum wear threshold, the position of the gear teeth is marked. During subsequent gear handling, this marking allows for rapid gear classification. This comprehensive contact detection of the gear tooth surfaces significantly improves the accuracy of gear precision testing.

[0027] By setting a drive block, a first lead screw, and a movable block inside the mounting frame, and using two first lead screws to drive four movable blocks to slide at the bottom of the mounting frame, the position of the movable blocks and the detection blocks can be adjusted. This allows the adjustment assembly to be applicable to the precision detection and adjustment of gears of different sizes, thus improving the applicability of the gear detection and adjustment mechanism.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figures 1 to 9 As shown, an adjustment mechanism for gear precision testing includes a fixed base frame 10, with a feeding platform 20 and a picking platform 30 respectively provided on both sides of the top of the fixed base frame 10, and an adjustment frame 40 also provided on the top of the fixed base frame 10 and between the feeding platform 20 and the picking platform 30.

[0041] A mounting bracket 50 is provided at the center of the top of the fixed base frame 10 and directly above the adjustment frame 40, and an adjustment component is provided inside the mounting bracket 50;

[0042] The adjustment assembly includes a mounting bracket 11, which is movably positioned below the mounting support 50. The mounting support 50 contains four first servo electric cylinders 12, with the drive ends of each cylinder connected to both sides of the mounting bracket 11. Slide grooves 13 are formed around the bottom of the mounting bracket 11, and movable blocks 14 are slidably positioned within each of the four slide grooves 13. A detection block 15 is mounted on the bottom of each movable block 14 via a micro-electric cylinder. By assembling the detection block 15, which engages with the teeth of the detection gear, at the bottom of the movable block 14, the wear condition of the gear teeth is detected. The four sets of detection blocks 15 can simultaneously detect the gear's precision, thereby significantly improving the efficiency of gear precision detection.

[0043] The detection block 15 is trapezoidal in shape, and each of the three inner walls of the detection block 15 is provided with a fixing block 16. Several detection rods 17 are movably arranged inside the fixing block 16, and spring sheets are sleeved on the surface of each detection rod 17. A pressure sensor 18 corresponding to the number of detection rods 17 is provided on one side of the inner wall of the fixing block 16. The force-receiving end of each pressure sensor 18 is in contact with one end of each detection rod 17. The force-receiving end of the pressure sensor 18 is pressured by one end of the detection rod 17, and the pressure data of the pressure sensor 18 is collected in real time. The detection end of the detection rod 17 is in contact with the tooth surface of the detection gear. When the tooth of the detection gear is worn, the detection end of the detection rod 17 extends outward. At this time, the pressure on the force-receiving end of the pressure sensor 18 decreases, so the pressure value of the pressure sensor 18 decreases. When the pressure value of the pressure sensor 18 is less than the maximum wear amount, the tooth position of the detection gear is marked.

[0044] Miniature electric cylinders are installed at the bottom of the mounting bracket 11 and on one side of the four movable blocks 14. Each of the four miniature electric cylinders has a marking block 19 at its drive end. After the teeth of the test gear are tested for accuracy by adjusting the assembly, the teeth of the gears that do not meet the accuracy standards are marked with the marking block 19. The marking block 19 is driven by the drive end of the miniature electric cylinder to mark the upper surface of the gear, which facilitates the subsequent maintenance of the test gear.

[0045] Furthermore, the mounting bracket 11 is internally equipped with a drive block 21, and the drive block 21 has two first lead screws 22 arranged in a cross shape. The two ends of the two first lead screws 22 are respectively connected to the internal threads of four movable blocks 14, and the two sides of the surface of the two first lead screws 22 are respectively provided with external threads with opposite directions. The two first lead screws 22 are located inside the drive block 21, and one end of each of the two first lead screws 22 is driven by a motor. The two first lead screws 22 respectively drive the four movable blocks 14 to slide at the bottom of the mounting bracket 11, thereby adjusting the position of the movable blocks 14 and the detection blocks 15. This allows the adjustment component to be used for the precision detection and adjustment of gears of different specifications and sizes, thus improving the applicability of the gear detection and adjustment mechanism.

[0046] Furthermore, a top plate 23 is bolted to the top of the mounting bracket 11, and a maintenance cover 24 is bolted to the top of the mounting bracket 50. The detachable design of the top plate 23 and the maintenance cover 24 allows for quick inspection of internal parts in case of malfunction of the adjustment mechanism.

[0047] Example 2

[0048] Both the feeding platform 20 and the unloading platform 30 are equipped with feeding components on their front sides. Each feeding component includes a movable frame 31, with a second lead screw 32 rotatably mounted inside the movable frame 31. Clamping frames 33 are threaded onto both sides of the surface of the second lead screw 32, and the two clamping frames 33 are slidably positioned on opposite sides inside the movable frame 31. The second lead screw 32 has external threads with opposite directions on both sides, and one end of the second lead screw 32 is driven by a motor. An electric slide is located on the front sides of the feeding platform 20 and the unloading platform 30, using the electric slide to drive the two feeding components during feeding. The device moves between the platform 20, the feeding platform 30, and the mounting bracket 50. When feeding and testing the detection gear, the second lead screw 32 rotates to drive the two clamping frames 33 to clamp the two sides of the detection gear. Then, the electric slide table sends the detection gear to the top of the adjustment frame 40 for precision testing. Sponge blocks are set on one side of each of the two clamping frames 33. The sponge blocks are used to adhere to the circumference of the gear to protect the integrity of the gear surface during the conveying process, while improving the stability of the gear during the conveying process and preventing the gear from slipping between the two clamping frames 33.

[0049] Example 3

[0050] The bottom of the fixed base frame 10 is provided with a mounting plate 41, and the top of the mounting plate 41 is provided with a second servo electric cylinder 42 around the top. The drive ends of the four second servo electric cylinders 42 are all connected to the bottom of the adjustment frame 40. The adjustment frame 40 is rotatably provided with a rotating frame 43, and the bottom of the rotating frame 43 is provided with a gear ring 44. The bottom of the rotating frame 43 is provided with a steering motor 45, and the output end of the steering motor 45 is provided with a drive gear 46 that meshes with the gear ring 44. The rotating frame 43 is provided with an electromagnet. After the detection gear is fed to the top of the rotating frame 43 by the feeding assembly, the electromagnet is used to limit the position of the detection gear on the rotating frame 43, thereby improving the stability of the detection gear during the adjustment process on the rotating frame 43.

[0051] A third servo electric cylinder 47 is also provided around the bottom of the mounting frame 11, and each of the drive ends of the third servo electric cylinder 47 is provided with a positioning plate 48. After the detection gear is sent to the top of the rotating frame 43, the four positioning plates 48 at the bottom of the mounting frame 11 are used to push the drive shaft of the third servo electric cylinder 47 to adjust the position of the detection gear on the rotating frame 43 to the center position. The micro electric cylinder pushes the detection block 15 downward, and the detection block 15 is used to perform precision detection on the teeth of the detection gear. Then, the output shaft of the steering motor 45 drives the gear ring 44 to rotate through the drive gear 46, adjusting the direction of the rotating frame 43, and then adjusting the orientation of the detection teeth of the detection gear on the rotating frame 43. The continuous detection processing of the teeth of the detection gear is realized through the four detection blocks 15, which significantly improves the detection efficiency of gear precision.

[0052] Example 4

[0053] Furthermore, this invention also discloses a method for using an adjustment mechanism for gear accuracy detection, the specific steps of which are as follows:

[0054] Step 1: Place the gear to be tested on the feeding table 20. Use the second lead screw 32 to rotate and drive the two clamping frames 33 to clamp the two sides of the gear to be tested. Drive the adjustment frame 40 downward through the drive end of the second servo electric cylinder 42. At this time, the gear to be tested is sent to the top of the adjustment frame 40 through the electric slide table and placed on the top of the adjustment frame 40.

[0055] Step 2: The drive end of the first servo cylinder 12 pushes the mounting bracket 11 downward, so that the four positioning plates 48 at the bottom of the mounting bracket 11 are above the adjustment bracket 40. Then, the drive shaft of the third servo cylinder 47 pushes the positioning plates 48 closer to the detection gear, and adjusts the position of the detection gear on the rotating bracket 43 to the center position.

[0056] Step 3: Select and install the corresponding detection blocks 15 according to the tooth specifications of the detection gear in advance. Then, adjust the position of the four detection blocks 15 by controlling the two first lead screws 22 so that the four detection blocks 15 are distributed at equal angles about the central axis of the detection gear.

[0057] Step 4: After adjusting the position of the detection gear on the rotating frame 43 to the center position, the micro electric cylinder pushes the detection block 15 downward. The detection block 15 is used to perform precision detection on the teeth of the detection gear. Then, the output shaft of the steering motor 45 drives the gear ring 44 to rotate through the drive gear 46, adjusting the direction of the rotating frame 43, and then adjusting the orientation of the detection teeth of the detection gear on the rotating frame 43. The continuous detection processing of the teeth of the detection gear is realized through the four detection blocks 15.

[0058] Step 5: Apply pressure to the force-receiving end of the pressure sensor 18 using one end of the detection rod 17, and collect the pressure data of the pressure sensor 18 in real time. Make the detection end of the detection rod 17 contact the tooth surface of the detection gear. When the teeth of the detection gear are worn, the detection end of the detection rod 17 extends outward. At this time, the pressure on the force-receiving end of the pressure sensor 18 decreases, so the pressure value of the pressure sensor 18 decreases. When the pressure value of the pressure sensor 18 is less than the maximum wear amount, use the drive end of the micro electric cylinder to drive the marking block 19 to mark the tooth position of the detection gear on the upper surface of the gear.

[0059] Step Six: After completing the precision inspection of the gear, the drive end of the second servo cylinder 42 drives the adjustment frame 40 to move downward. Then, the two clamping frames 33 on the front of the picking platform 30 move to the top of the adjustment frame 40. The drive end of the second servo cylinder 42 drives the adjustment frame 40 to move upward. The two clamping frames 33 clamp the two sides of the gear and send the inspected gear to the picking platform 30 for delivery, thus completing the automated precision inspection of the gear.

At this time, the pressure on the force-bearing end of the pressure sensor (18) decreases, so the pressure value of the pressure sensor (18) becomes smaller. When the pressure value of the pressure sensor (18) is less than the maximum wear amount, use the drive end of the micro electric cylinder to drive the marking block (19) to mark the upper surface of the gear tooth position. Step 6: After completing the precision test of the gear, the drive end of the second servo cylinder (42) drives the adjustment frame (40) to move downward. Then, the two clamping frames (33) on the front of the picking platform (30) move to the top of the adjustment frame (40). The drive end of the second servo cylinder (42) drives the adjustment frame (40) to move upward. The two clamping frames (33) clamp the two sides of the gear and send the tested gear to the picking platform (30) for delivery, thus completing the automated precision test of the gear.
