Description

Technical Field

[0001] The present invention relates to the technical field of gear detection, and particularly relates to a device for all-round laser detection of the tooth thickness of gear forgings. Background Art

[0002] In the gear manufacturing industry, for the detection of the tooth thickness of gear forgings, a series of significant defects have emerged in the existing technologies.

[0003] For example, in a gear parameter laser detection device and method with patent number CN 102322796 B and a gear parameter laser detection device with patent number CN 202149755 U, in terms of positioning, when conventional optical detection equipment fixes a gear, there is a lack of an effective structure for precise positioning from the inner ring of the gear. If the placement position of the gear on the detection table is slightly deviated, it will cause inconsistent reflection paths of light on the tooth surface. When the gear has a small displacement or tilt, it is difficult for measurement equipment based on optical principles to accurately capture the round-trip time of light, thereby resulting in a large error in the tooth thickness measurement data and seriously affecting the accuracy of the detection result.

[0004] From the perspective of the loading and unloading process, most current detection devices rely on manual operation. This not only requires a large amount of labor costs, but also in the frequent loading and unloading process, human negligence is extremely likely to cause collisions between gears, damage the surface of the gears, and reduce the gear quality. At the same time, the speed of manual operation is far from meeting the requirements of rapid detection in modern large-scale gear production, greatly restricting the improvement of production efficiency.

[0005] [[ID=URL]] In addition, in terms of the detection range, traditional optical detection equipment adopts a fixed optical path design. Facing gears with complex structures or special tooth profiles, light is extremely likely to be blocked, making it difficult to comprehensively scan all parts of the gear. As a result, there are many detection dead angles, and it is impossible to achieve all-round detection of the tooth thickness of the gear, making it difficult to meet the requirements for comprehensive control of gear quality in actual production. Summary of the Invention

[0006] To solve the technical problems existing in the background art, the present invention proposes a device for all-round laser detection of the tooth thickness of gear forgings to solve the deficiencies of the existing technologies in gear positioning, loading and unloading, and detection range, and achieve high-precision, high-efficiency, and all-round detection of the tooth thickness of gears.

[0007] The device for all-round laser detection of the tooth thickness of gear forgings proposed by the present invention includes:

[0008] A buffer positioning mechanism for positioning the gear from the inner ring of the gear and buffering and protecting the lower end face of the gear when it is placed;

[0009] An angle adjustment mechanism connected to the buffer positioning mechanism for rotating the buffer positioning mechanism to a vertical state or a horizontal state;

[0010] A control driving mechanism, which is docked with the buffer positioning mechanism and can drive the buffer positioning mechanism to rotate around its own axis, thereby driving the gear to rotate;

[0011] A laser measurement mechanism, which is arranged at the top of the device and is used to irradiate downward to measure the tooth thickness. Moreover, the laser measurement mechanism has the function of adjusting the position in the X-axis and Y-axis directions;

[0012] A loading and unloading mechanism, which is provided with a flipping claw and is used to grab the gear on the buffer positioning mechanism for loading and unloading, and can turn the gear over.

[0013] By setting the buffer positioning mechanism, the gear is prevented from being damaged when placed, ensuring the integrity of the detection; the angle adjustment mechanism can flexibly adjust the position of the gear according to the detection requirements, facilitating all-round detection; the control driving mechanism can accurately drive the gear to rotate, and cooperate with the position adjustment of the laser measurement mechanism in the X-axis and Y-axis directions to realize the accurate measurement of the tooth thickness at different positions of the gear; the flipping claw of the loading and unloading mechanism realizes the automatic loading and unloading and gear flipping operations, greatly improving the detection efficiency, reducing manual intervention, and enhancing the accuracy and stability of the detection.

[0014] Preferably, the buffer positioning mechanism includes:

[0015] A regular polygon column, with a piston column installed at the bottom, and tooth rails are provided on each side surface;

[0016] A cylinder, with a sealed bottom and an open top. The regular polygon column is located inside the cylinder cavity. The piston column and the cylinder can perform piston movement. A support spring for supporting the piston column is installed at the bottom of the cylinder. A number of rectangular slots are opened on the upper and lower sides of the cylinder side wall corresponding to the number of faces of the regular polygon column. A half gear is rotatably installed in each rectangular slot. The toothed side of the half gear is located inside the cylinder cavity and meshes with the tooth rail on the side surface of the regular polygon column. The toothless side is located outside the cylinder and is connected with an upwardly inclined support rod. The support rods of the upper and lower half gears in the same group of upper and lower rectangular holes are parallel to each other and the ends are hinged to a positioning bar, and the positioning bar is parallel to the axis of the cylinder;

[0017] A bearing frustum, which is horizontally and fixedly installed on the lower part of the outer side wall of the cylinder and is located below the lower rectangular hole;

[0018] A lifting plate, which is movably sleeved on the lower part of the outer wall of the cylinder and is parallel to the bearing frustum. A number of reset springs are connected between them. The upper surface of the lifting plate is circumferentially and arrayed with multiple groups of strip-shaped soft support members centered on the axis of the cylinder. The bearing frustum is provided with through grooves that are consistent with the number of support members and are vertically aligned. Under normal conditions, the top ends of the support members penetrate through the through grooves and expose above the upper surface of the bearing frustum;

[0019] The airbag is arranged between the opposite end surfaces of the lifting plate and the supporting circular platform. The movable connection between the lifting plate and the cylinder ensures airtightness. The bottom of the lifting plate is connected to two sets of air guide tubes for inflation and deflation, both of which are equipped with one-way valves. The lower side wall of the cylinder is provided with an air hole. The air hole diameter is smaller than the thickness of the lifting plate and is located below the piston column.

[0020] When the airbag begins to inflate, the lifting plate descends, and this downward movement first drives the support member downward. During this descent, the lifting plate completely seals the air holes, which then connect the cylinder cavity to the airbag. The injected gas then pushes the regular polygonal column upward through the piston, which in turn drives the positioning bar to expand, achieving gear positioning.

[0021] When the airbag is deflated, the lifting plate rises, first causing the air hole to be disconnected from the airbag, then the regular polygonal column falls, the positioning strip is retracted, and finally the support member is driven to rise to support the gear.

[0022] The buffering and positioning mechanism plays a key role during gear loading. Initially, the support member protruding from the bearing table first contacts the gear end face, providing buffering and protection. During this process, the return spring provides the lifting plate with a restoring force while also absorbing external forces at the moment of gear landing, further enhancing the buffering effect in conjunction with the support member.

[0023] When the airbag in the buffer positioning mechanism inflates, the lifting plate descends, driving the support member downward in tandem. As the support member continues to descend, the gear gradually transitions to being fully supported by the bearing platform. At this point, the subsequent effects of the airbag inflation become apparent: the injected gas pushes the piston rod upward, and the regular polygonal column deploys the positioning strip, achieving precise positioning from the inner ring of the gear, achieving a soft landing when loading.

[0024] This structural design enables coordinated control of the two systems simply by controlling the inflation and deflation of the airbag. During loading, the inflation operation causes the buffer support to smoothly retreat, allowing the bearing table to fully support the gear forging, creating conditions for the subsequent deployment of the positioning mechanism, automatically completing the buffering and positioning actions in sequence. After measurement, the airbag is deflated, and the positioning bar is first retracted, releasing the fixation on the inner ring of the gear. The support then rises due to the reset spring as the lifting plate ascends, providing protection for the gear during removal and effectively preventing gear damage.

[0025] Preferably, the angle adjustment mechanism includes:

[0026] Two sets of mounting frames, one of which is equipped with a first driving member;

[0027] A mounting platform is rotatably connected between the tops of the two mounting brackets via a first pin shaft, and the first driving member can rotate the mounting platform to a vertical state or a horizontal state via the pin shaft;

[0028] The bearing frustum of the buffer positioning mechanism is rotatably installed on the mounting table and rotates around its axis.

[0029] The angle adjustment mechanism is simple in structure and stable in operation. Through the first driving member, the angle conversion of the buffer positioning mechanism on the mounting table and the bearing frustum can be easily achieved. Whether in the vertical state or the horizontal state, it can provide different detection perspectives for the laser measurement mechanism, facilitating the comprehensive detection of the tooth thickness of each part of the gear, improving the comprehensiveness and accuracy of the detection, and at the same time facilitating the operator to flexibly adjust the detection posture according to the actual detection situation.

[0030] Preferably, the control driving mechanism includes:

[0031] A driven gear is installed at the bottom of the cylinder;

[0032] A second driving member, a telescopic rod and an air pump. A driving gear is installed on the second driving member for engaging with the driven gear;

[0033] The top of the telescopic rod is installed with a docking pipe. When the telescopic rod extends, it can be docked with the air guide pipe. A hose is connected between the air pump and the side wall of the docking pipe;

[0034] There are two groups of the control driving mechanism, namely the first control driving mechanism and the second control driving mechanism. When the buffer positioning mechanism is in the vertical state, the driving gear of the first control driving mechanism engages with the driven gear in the vertical direction; when the buffer positioning mechanism is in the horizontal state, the driving gear of the second control driving mechanism engages with the driven gear in the horizontal direction.

[0035] The two groups of control driving mechanisms respectively correspond to different states of the buffer positioning mechanism, and can accurately drive the buffer positioning mechanism to rotate around its own axis, ensuring that the gear can rotate stably in different postures and meeting the all-round detection requirements; the cooperation of the air pump, the telescopic rod and the air guide pipe realizes the automatic inflation and deflation control of the airbag in the buffer positioning mechanism, further improving the automation degree of the equipment operation, reducing the manual operation links, and improving the detection efficiency and accuracy.

[0036] Preferably, the laser measurement mechanism includes a laser emission module and a laser reception module, which are oppositely arranged and can synchronously adjust their positions in the X-axis and Y-axis directions to accurately measure the tooth thickness at different positions.

[0037] The relative arrangement of the laser emission module and the reception module and the synchronous adjustment function in the X-axis and Y-axis directions enable the laser measurement mechanism to flexibly align with each tooth thickness detection point of the gear. No matter what angle the gear is in, high-precision measurement can be achieved, effectively improving the accuracy and coverage of the tooth thickness measurement, providing reliable data support for the gear quality detection, and reducing the product misjudgment caused by measurement errors.

[0038] Preferably, the flipping claw includes:

[0039] A main frame, on which two sets of claw frames are slidably installed;

[0040] A third driving member and a rotating rod are installed on the main frame. Threads with opposite helix directions are provided at both ends of the rotating rod, and each thread is threadedly connected to a claw frame respectively;

[0041] Claw jaws are rotatably connected to the opposite surfaces of the two sets of claw frames through second pin shafts. A fourth driving member is installed on the claw frames, which can drive the claw jaws to rotate through the pin shafts and is used for turning over the gear;

[0042] The surface of the claw jaw in contact with the side wall of the gear is made of an elastic material, which can adapt to the size of the gear.

[0043] The design of the flipping claw is ingenious. By driving the rotating rod to rotate through the third driving member, the synchronous opening and closing of the two sets of claw frames are realized by using threads with opposite helix directions, which is convenient for grasping gears of different sizes; the fourth driving member controls the rotation of the claw jaws to turn over the gear, and the operation is simple and efficient; the elastic material of the surface of the claw jaw can not only effectively protect the surface of the gear from being scratched, but also enhance the adaptability to gears of different specifications, greatly improving the working efficiency of loading and unloading and gear turning over, and reducing the labor intensity of workers.

[0044] Preferably, the loading and unloading mechanism further includes a robotic arm, and the flipping claw is installed at the end of the robotic arm. The robotic arm can move flexibly to realize the precise loading and unloading operation of the gear.

[0045] The combination of the robotic arm and the flipping claw endows the loading and unloading mechanism with extremely high flexibility and precision. The robotic arm can move freely in three-dimensional space, and can quickly and accurately place the gear on the buffer positioning mechanism or take it off from it, realizing an automated loading and unloading process, reducing the errors and time losses that may be caused by manual handling, improving the coherence and efficiency of the entire detection process, and meeting the gear detection requirements in modern large-scale production.

[0046] Preferably, the device is also equipped with a control system, which is electrically connected to the first driving member of the angle adjustment mechanism, the second driving member of the control driving mechanism, the air pump, the third driving member and the fourth driving member of the loading and unloading mechanism respectively, and is used to coordinate the operation of each mechanism uniformly.

[0047] The setting of the control system makes the entire detection device form an organic whole. By electrically connecting the driving components of each mechanism, it can accurately control each mechanism to work in coordination according to a predetermined program. Whether it is angle adjustment, gear rotation, airbag inflation and deflation, or loading and unloading and gear turning over operations, they can all be carried out in an orderly manner under the unified scheduling of the control system, greatly improving the stability and detection efficiency of the equipment operation, reducing the interference of human factors, and ensuring the accuracy and consistency of the detection results.

[0048] In the present invention, a gear forging tooth thickness omnidirectional laser detection device proposed has the following beneficial effects:

[0049] 1. Precise positioning and buffer protection: The buffer positioning mechanism controls the actions of the support member and the positioning strip through the airbag. When the gear is placed, the support member first provides buffer protection to the lower end face of the gear. After the gear is stable, the positioning strip unfolds to precisely position the gear from the inner circle, avoiding damage to the gear and ensuring the positioning accuracy.

[0050] 2. Multi-angle detection: The angle adjustment mechanism can rotate the buffer positioning mechanism to the vertical or horizontal state, combined with controlling the drive mechanism to drive the gear to rotate around its own axis, and cooperating with the laser measurement mechanism to adjust the position in the X-axis and Y-axis directions, enabling omnidirectional measurement of the gear tooth thickness and meeting different detection requirements.

[0051] 3. Efficient loading and unloading and flipping: The end of the robotic arm of the loading and unloading mechanism is equipped with a flipping claw, which can flexibly grasp the gear for loading and unloading, and can drive the claw to rotate through the fourth driving member to flip the gear, improving the work efficiency.

[0052] 4. System coordinated operation: The control system coordinates the operation of each mechanism uniformly. Each driving member and the air pump are centrally controlled by the control system, ensuring the stability and accuracy of the device operation, reducing manual intervention, and improving the automation level of the detection process.

[0053] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. Brief Description of the Drawings

[0076] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference signs denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0077] As Figures 1 - 11 shown, a full - range laser detection device for the tooth thickness of a gear forging;

[0078] As Figure 1 shown: Overall structure: This device mainly consists of a buffer positioning mechanism 1, an angle adjustment mechanism 2, a control driving mechanism 3, a laser measurement mechanism 4, a loading and unloading mechanism 5, as well as a control system and a base. Each mechanism works together to ensure the comprehensiveness and accuracy of gear tooth thickness detection.

[0079] Buffer positioning mechanism 1:

[0080] As Figures 1 - 6 shown:

[0081] A piston column 1012 is installed at the bottom of a regular polygon column 101. Tooth tracks 1011 are provided on each side surface of the regular polygon column 101. The regular polygon column 101 is located inside the cavity of a cylinder 102 with a sealed bottom and an open top. The piston column 1012 can perform piston movement with the cylinder 102. A support spring 1013 is installed at the bottom of the cylinder 102 to support the piston column 1012. In this embodiment, the end face of the regular polygon column 101 is a regular pentagon;

[0082] Several rectangular slots 1021 are opened on the upper and lower sides of the side wall of the cylinder 102 corresponding to the number of faces of the regular polygon column 101. A half - gear 1022 is rotatably installed in each rectangular slot 1021. The toothed side of the half - gear 1022 is located inside the cavity of the cylinder 102 and meshes with the tooth track 1011 on the side surface of the regular polygon column 101. The toothless side is located outside the cylinder 102 and is connected to an upward - inclined support rod 1023. The support rods 1023 of the half - gears 1022 in the same group of upper and lower rectangular holes are parallel to each other and the ends are hinged to a positioning bar 1024, and the positioning bar 1024 is parallel to the axis of the cylinder 102.

[0083] A bearing frustum 103 is horizontally and fixedly installed on the lower part of the outer side wall of the cylinder 102, located below the lower rectangular hole. A lifting plate 104 is movably sleeved on the lower part of the outer wall of the cylinder 102, parallel to the bearing frustum 103, and several return springs 1042 are connected between them. On the upper surface of the lifting plate 104, a plurality of groups of strip - shaped soft support members 1041 are circumferentially arranged around the axis of the cylinder 102. Through slots 1031 that are consistent in number with the support members 1041 and are vertically aligned are opened through the bearing frustum 103.

[0084] The airbag 1043 is arranged between the opposite end faces of the lifting plate 104 and the bearing frustum 103. The connection part between the lifting plate 104 and the cylinder 102 ensures airtightness. The bottom of the lifting plate 104 is connected with two groups of air guide pipes 1044 respectively for inflation and deflation, and both are equipped with one-way valves. An air hole 1014 is opened on the lower side wall of the cylinder 102. The aperture of the air hole 1014 is smaller than the thickness of the lifting plate 104 and is located below the piston rod 1012. By inflating and deflating the airbag 1043, the coordinated movement of the support member 1041 and the positioning strip 1024 can be realized, so as to accurately position and buffer protect the gear.

[0085] Angle adjustment mechanism 2:

[0086] As Figures 7 - 9 shown:

[0087] It includes two groups of mounting brackets 201, and a first driving member 202 is mounted on one of the mounting brackets 201. The tops of the two groups of mounting brackets 201 are rotatably connected to the mounting table 204 through a first pin shaft 203. The first driving member 202 can rotate the mounting table 204 to a vertical state or a horizontal state through the pin shaft. The bearing frustum 103 of the buffer positioning mechanism 1 is rotatably mounted on the mounting table 204 and rotates around its axis, so as to realize flexible adjustment of the angle of the buffer positioning mechanism 1 and meet different detection requirements.

[0088] Control driving mechanism 3:

[0089] As Figures 8 - 10 shown:

[0090] The bottom of the cylinder 102 is mounted with a driven gear 307. The control driving mechanism 3 includes a second driving member 301, a telescopic rod 303 and an air pump 305. A driving gear 302 is mounted on the second driving member 301 for engaging with the driven gear �07.

[0091] The top of the telescopic rod 303 is mounted with a docking pipe 304, which can be docked with the air guide pipe 1044 when it extends. A hose 306 is connected between the air pump 305 and the side wall of the docking pipe 304. Two groups of control driving mechanisms 3 are provided, which are respectively engaged with the driven gear 307 when the buffer positioning mechanism 1 is in a vertical or horizontal state, so as to realize the driving of the buffer positioning mechanism 1 and the control of the inflation and deflation of the airbag 1043.

[0092] There are two groups of control driving mechanisms 3, namely the first control driving mechanism 31 and the second control driving mechanism 32. When the buffer positioning mechanism 1 is in a vertical state, the driving gear 302 of the first control driving mechanism 31 is engaged with the vertically oriented driven gear 307; when the buffer positioning mechanism 1 is in a horizontal state, the driving gear 302 of the second control driving mechanism 32 is engaged with the horizontally oriented driven gear 307.

[0093] Laser measurement mechanism 4: It is arranged at the top of the device and includes a laser emission module and a laser reception module that are oppositely arranged. The two can synchronously adjust their positions in the X-axis and Y-axis directions. By emitting and receiving laser, the round-trip time of the laser is measured, and then the tooth thickness is accurately calculated.

[0094] Loading and unloading mechanism 5: It is equipped with a robotic arm, and a flipping claw 501 is installed at the end of the robotic arm.

[0095] As Figure 11 shown:

[0096] Two groups of claw frames 5014 are slidably installed on the main frame 5011 of the flipping claw 501. The main frame 5011 is installed with a third driving member 5012 and a rotating rod 5013. Threads with opposite helix directions are provided at both ends of the rotating rod 5013 and are respectively threadedly connected to a claw frame 5014. The opposite surfaces of the two groups of claw frames 5014 are rotatably connected to a claw 5016 through a second pin shaft 5015. A fourth driving member 5017 is installed on the claw frame 5014, and the claw 5016 can be driven to rotate through the pin shaft, realizing the grasping, loading and unloading, and flipping operations of the gear.

[0097] Control system: It is electrically connected to the first driving member 202 of the angle adjustment mechanism 2, the second driving member 301 of the control driving mechanism 3, the air pump, 305, the third driving member 5012 and the fourth driving member 5017 of the loading and unloading mechanism 5, and coordinates the operation of each mechanism uniformly to ensure the stable and efficient operation of the device.

[0098] In the working process of this embodiment:

[0099] Working principle:

[0100] Buffer positioning principle: When the airbag 1043 is inflated, the lifting plate 104 descends, driving the support member 1041 to descend. At the same time, the lifting plate 104 seals the air hole 1014, so that the air hole 1014 connects the inner cavity of the cylinder 102 with the airbag 1043. The gas filled pushes the piston column 1012 to rise, and the regular polygon column 101 rises to drive the positioning strip 1024 to unfold, positioning the gear from the inner ring of the gear; when the airbag 1043 deflates, the lifting plate 104 rises, the air hole 1014 is disconnected from the airbag 1043, the regular polygon column 101 falls, the positioning strip 1024 is retracted, and the support member 1041 rises to support the gear.

[0101] Angle adjustment principle: The first driving member 202 of the angle adjustment mechanism 2 drives the mounting table 204 to rotate through the pin shaft. The rotation of the mounting table 204 can change the angle of the buffer positioning mechanism 1, realizing the switching between the vertical and horizontal states.

[0102] Control and drive principle: The second driving part 301 of the control and drive mechanism 3 drives the driving gear 302 to rotate. The driving gear 302 is clamped and engaged with the driven gear 307 at the bottom of the cylinder 102, driving the buffer positioning mechanism 1 and the gear to rotate. The telescopic rod 303 extends under the command of the control system, and the docking pipe 304 at its top is accurately docked with the air guide pipe 1044 at the bottom of the lifting plate 104 of the buffer positioning mechanism 1. The air pump 305 is connected to the docking pipe 304 through the hose 306. When the air pump 305 is started, the gas enters the airbag 1043 through the hose 306, the docking pipe 304 and the air guide pipe 1044, realizing the inflation operation of the airbag 1043; similarly, when the air pump 305 works in the reverse direction, the gas in the airbag 1043 can be pumped out to realize deflation, thereby realizing the control of the buffer positioning mechanism 1. The one-way valve can prevent the airbag 1043 from leaking air.

[0103] Laser measurement principle: The laser emission module of the laser measurement mechanism 4 emits laser downward, and the laser reception module receives the reflected light, and calculates the tooth thickness by measuring the round-trip time of the laser. And the laser emission module and the reception module can be synchronously adjusted in the X-axis and Y-axis directions to measure the tooth thickness at different positions.

[0104] Loading and unloading principle: The robotic arm drives the flipping claw 501 to move to the gear position. The third driving part 5012 drives the rotating rod 5013 to rotate, so that the two sets of claw frames 5014 move relatively or away from each other to grasp the gear. The fourth driving part 5017 drives the claw 5016 to rotate through the pin shaft, realizing the flipping of the gear and completing the loading and unloading operation.

[0105] Working steps

[0106] Loading: The robotic arm of the loading and unloading mechanism 5 moves to the gear to be detected. The flipping claw 501 adjusts the distance between the claw frames 5014 through the third driving part 5012 to grasp the gear, and then transports the gear above the buffer positioning mechanism 1 and slowly puts it down.

[0107] Positioning: The airbag 1043 of the buffer positioning mechanism 1 is inflated, the support 1041 descends, the gear falls on the bearing turntable 103, and the positioning strip 1024 unfolds to position the gear from the inner circle.

[0108] Angle adjustment: According to the detection requirements, the first driving part 202 of the angle adjustment mechanism 2 works to rotate the buffer positioning mechanism 1 to the vertical or horizontal state.

[0109] Detection: The control and drive mechanism 3 drives the gear to rotate. The laser measurement mechanism 4 adjusts its position in the X-axis and Y-axis directions to perform a full-range measurement of the gear tooth thickness, and the measurement data is recorded in real time.

[0110] Turning over and secondary detection: If it is necessary to detect the other side of the gear, the flipping claws 501 of the loading and unloading mechanism 5 grab the gear, and the fourth driving part 5017 drives the clamping claws 5016 to rotate to turn over the gear, and then place it on the buffer positioning mechanism 1 again, and repeat steps 3 - 4 for secondary detection.

[0111] Unloading: After the detection is completed, the airbag 1043 deflates, the positioning strip 1024 retracts, and the support 1041 rises. The robotic arm of the loading and unloading mechanism 5 transports the gear to the designated position to complete the unloading operation.
