Description
Technical Field
[0001] The invention relates to the technical field of gear detection, and in particular to an omnidirectional laser detection device for tooth thickness of a gear forging. Background Art
[0002] In the gear manufacturing industry, the existing technology for detecting the tooth thickness of gear forgings has exposed a series of significant defects. For example, patent number CN 102322796 B, a gear parameter laser detection device and method, and CN 202149755 U, a gear parameter laser detection device, in terms of positioning, conventional optical detection equipment lacks an effective structure for precise positioning from the inner ring of the gear when fixing the gear. A slight deviation in the placement of the gear on the test bench will cause the reflection path of the light on the tooth surface to be inconsistent. When the gear is slightly displaced or tilted, it is difficult for the optically based measurement equipment to accurately capture the round-trip time of the light, which in turn causes large errors in the tooth thickness measurement data, seriously affecting the accuracy of the test results. From the perspective of loading and unloading processes, most of the current detection devices rely on manual operation. This not only requires a lot of manpower costs, but also in the frequent loading and unloading process, manual negligence can easily cause collisions between gears, causing damage to the gear surface and reducing gear quality. At the same time, the speed of manual operation is far from meeting the needs of rapid detection in modern large-scale gear production, which greatly restricts the improvement of production efficiency. In addition, in terms of detection range, traditional optical detection equipment adopts a fixed light path design. When facing gears with complex structures or special tooth shapes, the light is easily blocked, making it difficult to fully scan all parts of the gear. This results in many detection blind spots, making it impossible to achieve all-round detection of gear tooth thickness, and it is difficult to meet the requirements for comprehensive control of gear quality in actual production. Summary of the invention
[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a full-range laser detection device for gear forging tooth thickness to solve the shortcomings of the prior art in gear positioning, loading and unloading, and detection range, and to achieve high-precision, high-efficiency and full-range gear tooth thickness detection.
[0004] The present invention provides a omnidirectional laser detection device for tooth thickness of gear forgings, comprising: The buffer positioning mechanism is used to position the gear from the inner ring of the gear and to provide buffer protection to the lower end surface of the gear when it is placed; An angle adjustment mechanism, connected to the buffer positioning mechanism, used to rotate the buffer positioning mechanism to a vertical state or a horizontal state; The control driving mechanism is connected with the buffer positioning mechanism, and can drive the buffer positioning mechanism to rotate around its own axis, thereby driving the gear to rotate; A laser measuring mechanism is arranged on the top of the device and is used to irradiate downward to measure the tooth thickness. The laser measuring mechanism has the function of adjusting the position in the X-axis and Y-axis directions. The loading and unloading mechanism is provided with a turning claw, which is used to grab the gear on the buffer positioning mechanism for loading and unloading, and can turn the gear over.
[0005] By setting up a buffer positioning mechanism, the gears can be prevented from being damaged during placement, thus ensuring the integrity of the inspection. The angle adjustment mechanism can flexibly adjust the gear position according to the inspection requirements, facilitating all-round inspection. The control drive mechanism can accurately drive the gears to rotate, and cooperate with the laser measurement mechanism to adjust the position in the X-axis and Y-axis directions to achieve accurate measurement of the tooth thickness at different positions of the gears. The flip claws of the loading and unloading mechanism realize automated loading and unloading and gear flipping operations, greatly improving the inspection efficiency, reducing manual intervention, and improving the accuracy and stability of inspection.
[0006] Preferably, the buffer positioning mechanism comprises: A regular polygonal column with a piston column mounted at the bottom and racks on all sides; A cylinder, with a sealed bottom and an open top, wherein the regular polygonal column is located in the inner cavity of the cylinder, the piston column and the cylinder can perform piston motion, a support spring for supporting the piston column is installed at the bottom of the cylinder, a number of rectangular grooves are opened at the upper and lower parts of the side walls of the cylinder corresponding to the number of faces of the regular polygonal column, a half gear is rotatably installed in each rectangular groove, the toothed side of the half gear is located in the inner cavity of the cylinder and meshes with the gear rail on the side of the regular polygonal column, and the toothless side is located outside the cylinder and connected to an upwardly inclined support rod, the support rods of the half gears in the same group of upper and lower rectangular holes are parallel to each other and the ends are hinged to positioning strips, and the positioning strips are parallel to the axis of the cylinder; The load-bearing round platform is horizontally fixedly installed on the lower part of the outer wall of the cylinder and is located below the lower rectangular hole; The lifting plate is movably sleeved on the lower part of the outer wall of the cylinder and is parallel to the bearing truncated platform. A number of reset springs are connected between the two. A plurality of groups of long strip soft support members are arranged in a circular array around the axis of the cylinder on the upper surface of the lifting plate. The bearing truncated platform is provided with through slots that are the same in number as the support members and are directly opposite to each other up and down. In a normal state, the top of the support member passes through the through slot and is exposed on the upper surface of the bearing truncated platform; The airbag is arranged between the opposite end faces of the lifting plate and the supporting truncated table. The movable connection between the lifting plate and the cylinder ensures air tightness. The bottom of the lifting plate is connected with two sets of air guide pipes respectively used for inflation and deflation and both are equipped with one-way valves. The lower side wall of the cylinder is provided with an air hole, the diameter of which is smaller than the thickness of the lifting plate and is located below the piston column. When the airbag starts to inflate, the lifting plate descends, and the descending action first drives the support member to descend. During the descent of the lifting plate, the lifting plate first completely seals the air hole, and then the air hole connects the inner cavity of the cylinder with the airbag. Then, the filled gas pushes the regular polygon column up through the piston column, which in turn drives the positioning strip to unfold, thus realizing the positioning of the gear; 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 down, the positioning strip is retracted, and finally the supporting member is driven up to support the gear.
[0007] During the gear feeding process, the buffer positioning mechanism plays a key role. In the initial state, the support member protruding from the bearing truncated table first contacts the gear end face and assumes the responsibility of buffer protection. During this process, the return spring provides the lifting plate with a return force on the one hand, and absorbs external force at the moment of gear landing on the other hand, and cooperates with the support member to further enhance the buffer effect.
[0008] When the airbag of the buffer positioning mechanism is inflated, the lifting plate descends, driving the support member to move down synchronously. As the support member continues to descend, the gear gradually transitions to being fully supported by the load-bearing truncated table. At this time, the subsequent effect caused by the inflation of the airbag appears. The gas pushes the piston column up, and the regular polygon column drives the positioning strip to unfold, achieving precise positioning from the inner ring of the gear, achieving a soft landing effect when loading.
[0009] This structural design can realize linkage control of the two systems only by controlling the inflation and deflation of the airbag. When loading, the inflation operation makes the buffer support member retreat smoothly, and the bearing round table fully supports the gear forging, creating conditions for the subsequent deployment of the positioning mechanism, and automatically completing the buffering and positioning actions in sequence. After the measurement is completed, the airbag is deflated, the positioning bar is retracted first, and the fixation on the inner ring of the gear is released. Then the support member rises under the action of the reset spring during the rising process of the lifting plate, and provides protection for the gear again when it is removed, effectively avoiding gear damage.
[0010] Preferably, the angle adjustment mechanism comprises: Two sets of mounting frames, one of which is equipped with a first driving member; A mounting platform is rotatably connected between the tops of the two mounting frames 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; The bearing truncated table of the buffer positioning mechanism can be rotatably mounted on the mounting table and rotate around its axis.
[0011] The angle adjustment mechanism has a simple structure and stable operation. The angle conversion of the buffer positioning mechanism on the mounting table and the load-bearing circular table can be easily realized through the first driving member. Whether in a vertical state or a horizontal state, it can provide different detection viewing angles for the laser measurement mechanism, which is convenient for comprehensive detection of the tooth thickness of each part of the gear, thereby improving the comprehensiveness and accuracy of the detection. At the same time, it is also convenient for the operator to flexibly adjust the detection posture according to the actual detection situation.
[0012] Preferably, the control drive mechanism comprises: A driven gear is installed at the bottom of the cylinder; A second driving member, a telescopic rod and an air pump, wherein the second driving member is provided with a driving gear for engaging with a driven gear; A butt joint is installed at the top of the telescopic rod, and the telescopic rod can be butt jointed with the air guide pipe when extended, and a hose is connected between the air pump and the side wall of the butt joint; The control drive mechanism is provided with two groups, namely a first control drive mechanism and a second control drive mechanism. When the buffer positioning mechanism is in a vertical state, the driving gear of the first control drive mechanism is engaged with the driven gear in the vertical direction; when the buffer positioning mechanism is in a horizontal state, the driving gear of the second control drive mechanism is engaged with the driven gear in the horizontal direction.
[0013] The two sets of control drive mechanisms correspond to the different states of the buffer positioning mechanism, and can accurately drive the buffer positioning mechanism to rotate around its own axis, ensuring that the gears can rotate stably in different postures and meet all-round detection needs; the cooperation of the air pump, telescopic rod and air guide tube realizes the automatic inflation and deflation control of the airbag in the buffer positioning mechanism, further improving the degree of automation of equipment operation, reducing manual operation links, and improving detection efficiency and accuracy. Preferably, the laser measuring mechanism comprises a laser emitting module and a laser receiving module, which are arranged relative to each other and can be synchronously adjusted in the X-axis and Y-axis directions to accurately measure the tooth thickness at different positions.
[0014] The relative setting of the laser transmitting module and the receiving 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 at, high-precision measurement can be achieved, which effectively improves the accuracy and coverage of tooth thickness measurement, provides reliable data support for gear quality inspection, and reduces product misjudgment caused by measurement errors.
[0015] Preferably, the turning claw comprises: A main frame, on which two sets of claw frames are slidably mounted; The main frame is provided with a third driving member and a rotating rod, and both ends of the rotating rod are provided with threads with opposite rotation directions, and each thread is respectively connected with a claw frame thread; The opposite surfaces of the two groups of claw frames are rotatably connected with claws through the second pin shaft, and a fourth driving member is installed on the claw frame, which can drive the claw to rotate through the pin shaft to turn over the gear; The surface where the claw contacts the side wall of the gear is made of elastic material and can adapt to the size of the gear.
[0016] The flipping claw is cleverly designed. The third driving member drives the rotating rod to rotate, and the two sets of claw frames are opened and closed synchronously by using threads with opposite rotation directions, which is convenient for grabbing gears of different sizes. The fourth driving member controls the rotation of the claw to flip the gear, which is easy and efficient to operate. The claw surface made of elastic material can not only effectively protect the gear surface from being scratched, but also enhances the adaptability to gears of different specifications, greatly improving the efficiency of loading and unloading and gear flipping, and reducing manual labor intensity.
[0017] Preferably, the loading and unloading mechanism further includes a mechanical arm, and the flip claw is installed at the end of the mechanical arm. The mechanical arm can be flexibly moved to realize precise loading and unloading operations of the gears.
[0018] The combination of the robotic arm and the flip claw gives the loading and unloading mechanism extremely high flexibility and precision. The robotic arm can move freely in three-dimensional space, and can quickly and accurately place the gear on or remove it from the buffer positioning mechanism, realizing the automated loading and unloading process, reducing the errors and time loss that may be caused by manual handling, improving the consistency and efficiency of the entire detection process, and meeting the gear detection needs in modern large-scale production.
[0019] Preferably, the device is also equipped with a control system, which is electrically connected to the first drive member of the angle adjustment mechanism, the second drive member of the control drive mechanism, the air pump, the third drive member and the fourth drive member of the loading and unloading mechanism, respectively, for unified coordination of the operation of each mechanism.
[0020] The setting of the control system makes the whole detection device an organic whole. By electrically connecting the driving components of each mechanism, it can accurately control each mechanism to work together according to the predetermined program. Whether it is angle adjustment, gear rotation, airbag inflation and deflation, or loading and unloading and gear flipping, all operations can be carried out in an orderly manner under the unified dispatch of the control system, which greatly improves the stability of equipment operation and detection efficiency, reduces interference from human factors, and ensures the accuracy and consistency of the detection results.
[0021] In the present invention, a gear forging tooth thickness omnidirectional laser detection device is proposed, which has the following beneficial effects: 1. Precise positioning and buffer protection: The buffer positioning mechanism controls the movement of the support and the positioning strip through the airbag. When the gear is placed, the support first buffers the lower end face of the gear. After the gear is stable, the positioning strip unfolds to accurately position the gear from the inner ring to avoid damage to the gear and ensure positioning accuracy.
[0022] 2. Multi-angle detection: The angle adjustment mechanism can rotate the buffer positioning mechanism to a vertical or horizontal state, and combined with the control drive mechanism to drive the gear to rotate around its own axis, and cooperate with the laser measurement mechanism to adjust the position in the X-axis and Y-axis directions, it can realize all-round measurement of gear tooth thickness to meet different detection needs.
[0023] 3. Efficient loading and unloading and turning over: A turning claw is installed at the end of the mechanical arm of the loading and unloading mechanism, which can flexibly grab the gear for loading and unloading, and can drive the claw to rotate and turn the gear over through the fourth driving member to improve work efficiency.
[0024] 4. System coordinated operation: The control system coordinates the operation of various mechanisms. Each drive component and air pump is centrally controlled by the control system to ensure the stability and accuracy of the device operation, reduce manual intervention, and improve the degree of automation of the detection process. Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

By emitting and receiving lasers, the round-trip time of the laser is measured, and the tooth thickness is accurately calculated.
[0036] The loading and unloading mechanism 5 is provided with a mechanical arm, and a turning claw 501 is installed at the end of the mechanical arm.
[0037] like Fig.11 As shown: Two groups of claw frames 5014 are slidably mounted on the main frame 5011 of the flip claw 501, and the main frame 5011 is mounted with a third driving member 5012 and a rotating rod 5013. The two ends of the rotating rod 5013 are provided with threads with opposite rotation directions, which are respectively threadedly connected with one claw frame 5014. The opposite surfaces of the two groups of claw frames 5014 are rotatably connected with the clamping claw 5016 through the second pin shaft 5015. The fourth driving member 5017 is mounted on the claw frame 5014, which can drive the clamping claw 5016 to rotate through the pin shaft, so as to realize the operations of grabbing, loading and unloading, and turning over the gear.

The air pump 305 is connected to the docking tube 304 through the hose 306. When the air pump 305 is started, the gas enters the airbag 1043 through the hose 306, the docking tube 304 and the air guide tube 1044 to realize 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 extracted to realize deflation, thereby realizing the control of the buffer positioning mechanism 1, and the one-way valve can prevent the airbag 1043 from leaking.
[0042] Laser measurement principle: The laser emitting module of the laser measuring mechanism 4 emits laser downwards, and the laser receiving module receives the reflected light, and the tooth thickness is calculated by measuring the round trip time of the laser. The laser emitting module and the receiving module can be adjusted synchronously in the X-axis and Y-axis directions to measure the tooth thickness at different positions.
[0043] Loading and unloading principle: the mechanical arm drives the flip claw 501 to move to the gear position, the third driving member 5012 drives the rotating rod 5013 to rotate, so that the two sets of claw frames 5014 move relative to or opposite to each other to grab the gear. The fourth driving member 5017 drives the claw 5016 to rotate through the pin shaft to realize the gear flipping and complete the loading and unloading operation.
[0044] Working steps Loading: The mechanical arm of the loading and unloading mechanism 5 moves to the gear to be detected, and the flip claw 501 adjusts the spacing of the claw frame 5014 through the third driving member 5012 to grab the gear, and then moves the gear to the top of the buffer positioning mechanism 1 and slowly puts it down.
[0045] Positioning: The airbag 1043 of the buffer positioning mechanism 1 is inflated, the support member 1041 descends, the gear falls on the supporting truncated table 103, the positioning strip 1024 unfolds, and the gear is positioned from the inner ring.
[0046] Angle adjustment: According to the detection requirements, the first driving member 202 of the angle adjustment mechanism 2 works to rotate the buffer positioning mechanism 1 to a vertical or horizontal state.
[0047] Detection: Control the driving mechanism 3 to drive the gear to rotate, and the laser measuring mechanism 4 adjusts the position in the X-axis and Y-axis directions to measure the gear tooth thickness in all directions, and the measurement data is recorded in real time.
[0048] Turning over and secondary inspection: If the other side of the gear needs to be inspected, the turning claw 501 of the loading and unloading mechanism 5 grabs the gear, and the fourth driving member 5017 drives the claw 5016 to rotate to turn the gear over and re-place it on the buffer positioning mechanism 1, and repeat steps 3-4 for secondary inspection.
[0049] Unloading: After the inspection is completed, the airbag 1043 is deflated, the positioning bar 1024 is retracted, and the support member 1041 rises. The mechanical arm of the loading and unloading mechanism 5 moves the gear to the designated position to complete the unloading operation.
