Description

Technical Field

[0001] The invention belongs to the technical field of gear processing equipment, and in particular relates to a matching degree detection device for gear processing. Background Art

[0002] After the gears are machined and formed, it is usually necessary to detect their matching degree (such as the cumulative error of the pitch, the radial runout of the gear ring, etc.) to ensure the transmission accuracy and performance of the gears, because the matching degree of the gears directly affects the load-bearing capacity and life of the gear transmission system. By detecting the matching degree, it can be ensured that the parameters such as the gear tooth shape and pitch match the design requirements, thereby ensuring the accuracy and performance of the transmission and improving the processing accuracy. Gear detection is an important means to analyze the source of gear processing errors and improve the gear processing accuracy. Through matching degree detection, errors in the processing process can be found, and the processing parameters can be adjusted in time to improve the processing accuracy of the gears. For example, a Chinese patent discloses a matching degree detection device for gear processing (patent publication number: CN114674553A), which automatically adjusts the angles of two sets of gears to be tested during the process of moving toward each other through an adjustment component, so that the two sets of gears to be tested can accurately enter the meshing state after contact, avoiding the phenomenon of teeth of the two sets of gears to be tested hitting each other due to angle deviation. At the same time, there is no need to manually adjust the gears, which improves the detection efficiency and safety of the gear meshing degree detection process.

[0003] Although the above technical scheme provides a gear matching detection device, which can effectively solve the problem of tooth playing during the meshing process of the gear to be tested, in the actual production and processing process, it is usually necessary to perform meshing matching detection on a large number of gears to be tested. When using the detection device in the comparative document, the staff is required to repeatedly disassemble the gear to be tested and install it on the clamping assembly, and then adjust the angle of the gear to be tested by adjusting the assembly, which greatly increases the burden on the staff and the construction process. Therefore, based on this technical problem, the present invention provides an assembly line automated gear matching detection device, which is used to improve the efficiency of the current large-scale matching detection of gears to be tested.

The upper surface of the operating table is provided with a detection unit corresponding to the standard gear. When any of the gears to be measured moves toward the direction of the standard gear under the action of the moving platform, the gear to be measured first meshes with the rack and meshes with the standard gear under its guiding action. Then the moving platform continues to move until the gear to be measured is no longer meshed with the rack. At this time, the working end of the detection unit faces the meshing position of the gear to be measured and the standard gear and performs a matching detection on them.

[0008] Furthermore, the adjustment unit also includes a slider movably arranged between the upper surface of the fixed seat and the rack and a second drive motor that drives the slider to move, the slider is elastically slidably arranged on the upper surface of the fixed seat along the length direction of the rack, the rack is elastically hinged on the upper surface of the slider, the second drive motor is arranged on the surface of the fixed seat, and the output end of the second drive motor is connected to a connecting piece that drives the slider to reciprocate linearly along the length direction of the rack.

DETAILED DESCRIPTION

[0029] like Figures 1 to 8 As shown,

[0030] A gear processing matching detection device comprises an operating table 1 and a transmission unit 3 installed on the upper surface of the operating table 1 for transporting a gear 2 to be tested. The operating table 1 is rectangular. The transmission unit 3 comprises a plurality of mobile platforms 301 that perform circular motion in a clockwise direction on a horizontal plane and a driving member 302 for driving all the mobile platforms 301 to move. The driving member 302 comprises a circularly arranged belt and a motor (combined with a belt) that drives the belt to move. Figure 1 As shown, its specific operation mode and principle are all existing technologies, which will not be described in detail), the upper surface of each of the mobile platforms 301 is rotatably connected with a vertical rotating shaft 4, and the outer ring of the rotating shaft 4 is sleeved and detachably connected with the coaxial gear to be tested 2, and each of the gears to be tested 2 is horizontally arranged and rotates synchronously with the rotating shaft 4 (the peripheral surface of the rotating shaft 4 is provided with a vertical transmission key, and the rotating shaft 4 rotates synchronously with the gear to be tested 2 through the transmission key); one side of the operating table 1 is provided with a support platform 5 fixed to the ground, and the upper surface of the support platform 5 is rotatably connected with a standard gear 6 for detecting the meshing degree of each gear to be tested 2, the standard gear 6 is horizontally arranged and is in the same horizontal plane with each gear to be tested 2, and the standard gear 6 is dynamically connected with a first driving motor 7 that drives it to rotate (the output end of the first driving motor 7 and the standard gear 6 can realize power transmission through the cooperation of multiple transmission gears, or through the cooperation of components such as belts and pulleys, and the specific method will not be described in detail), and the first driving motor 7 is vertically arranged and fixed on the surface of the supporting platform 5 by bolts;

[0031] The upper surface of the operating table 1 is provided with an adjustment unit 8 for correcting the angle of the gear 2 to be measured. The adjustment unit 8 is arranged before the position where the gear 2 to be measured is about to mesh with the standard gear 6. The adjustment unit 8 includes a fixed seat 801 and a rack 802 movably arranged on the upper surface of the fixed seat 801. The length of the rack 802 and the fixed seat 801 are arranged along the direction in which the gear 2 to be measured moves toward the standard gear 6, wherein the fixed seat 801 is "U"-shaped and is vertically fixed to the upper surface of the operating table 1 by bolts. The end of the rack 802 close to the standard gear 6 is elastically hinged on the surface of the fixed seat 801 and rotates in the horizontal plane (a torsion spring is provided at the rotating shaft 4 of the rack 802 to achieve elastic rotation), and the end of the rack 802 away from the standard gear 6 is slidably arranged on the surface of the fixed seat 801, wherein a side surface of the rack 802 with teeth faces the gear 2 to be measured; the upper surface of the operating table 1 is also provided with a detection unit 9 corresponding to the standard gear 6 (the detection unit 9 can adopt a grating sensor to and the data processing equipment matched therewith, the detection principle and application method thereof are already the prior art and will not be described in detail), the detection unit 9 is arranged just above the meshing point of the gear 2 to be tested and the standard gear 6, when any of the gears 2 to be tested moves toward the standard gear 6 under the drive of the mobile platform 301, the gear 2 to be tested first meshes with the end of the rack 802 away from the standard gear 6, and then the gear 2 to be tested continues to mesh with the rack 802 and rotates while moving, when the gear 2 to be tested moves to the end of the rack 802, the gear 2 to be tested just meshes with the standard gear 6, and then the mobile platform 301 continues to move until the gear 2 to be tested is no longer meshed with the rack 802, at this time, the transmission unit 3 stops for a period of time, the working end of the detection unit 9 faces the meshing point of the gear 2 to be tested and the standard gear 6 and performs a matching detection on it, after the detection is completed, the transmission unit 3 continues to work, and moves the next gear 2 to be tested toward the direction of the adjustment unit 8 and repeats the above-mentioned movement process of the gear 2 to be tested.

[0032] For ease of display, Figure 1Only a partial view of the operating table 1 and the transmission unit 3 is shown; multiple mobile platforms 301 rotate in the counterclockwise direction under the action of the driving member 302, and the staff can install multiple gears 2 to be tested that need to be tested for meshing degree on each mobile platform 301 respectively, and during the installation process, the gear 2 to be tested needs to be placed horizontally and coaxial with the rotating shaft 4, and then move vertically downward along the axis of the rotating shaft 4 and cooperate with the rotating shaft 4. The mobile platform 301 loaded with the gear 2 to be tested moves toward the adjustment unit 8 and the detection unit 9 under the action of the driving member 302. When this mobile platform 301 moves to the detection unit 9, the gear 2 to be tested on this mobile platform 301 first contacts with one end of the rack 802. Since the gear 2 to be tested is installed on the mobile platform 301 by the staff, the gear 2 to be tested 2 is not perfectly meshed with the rack 802 at an ideal angle (of course, the gear 2 to be tested will not be perfectly meshed with the standard gear 6). When one of the tooth tops of the gear 2 to be tested abuts against the rack 802, the rack 802 will deflect a short distance in the horizontal plane in the direction away from the gear 2 to be tested, so that the two tooth tops of the rack 802 and the gear 2 to be tested will not collide, thereby causing damage to the gear; there is also a situation where, when the rack 802 and the gear 2 to be tested are meshed, the tooth at one end of the rack 802 is exactly located between the two tooth roots on the gear 2 to be tested, and the gear 2 to be tested will abut against the rack 802 and rotate during the movement, thereby realizing the meshing between the rack 802 and the gear 2 to be tested, and avoiding the occurrence of tooth collision between the rack 802 and the gear 2 to be tested;When the gear 2 to be tested continues to move in the direction of the standard gear 6, the gear 2 to be tested will mesh with the rack 802 during the movement and generate self-rotation, so that the gear 2 to be tested will mesh with the standard gear 6 according to the predetermined trajectory (the standard gear 6 will stop at a specific angle under the action of the first drive motor 7, so as to mesh with the gear 2 to be tested that enters the predetermined trajectory), until the gear 2 to be tested is no longer meshed with the rack 802, and the mobile platform 301 stops moving for a period of time (of course, this position is provided with a trigger mechanism or related sensors, when the mobile platform 301 reaches this position, it can be sensed and stopped, we can call this position a detection station), at this time, the first drive member 302 drives the standard gear 6 and the gear 2 to be tested to rotate, and the detection end of the detection unit 9 continues to detect the gear 2 to be tested. The meshing part with the standard gear 6 is tested, and its test data is transmitted to the relevant equipment. After a period of testing, the first driving member 302 stops rotating at a specific angle (the angle after stopping rotation coincides with the position when it was previously meshed with the gear 2 to be tested), and the mobile platform 301 drives the gear 2 to be tested to continue to move counterclockwise and away from the gear 2 to be tested. Subsequently, the next gear 2 to be tested moves in the direction of the gear driven by the mobile platform 301 and repeats the above-mentioned work process. After the gear 2 to be tested that has been tested is removed by the staff, the gear 2 to be tested that has not been tested is replaced, realizing the large-scale, semi-automatic meshing degree testing of the gear 2 to be tested, greatly reducing the operating steps and workload of the staff, and effectively improving the meshing degree testing efficiency of the gear 2 to be tested. ;

[0033] In this embodiment, the adjustment unit 8 also includes a slider 803 movably arranged between the upper surface of the fixed seat 801 and the lower surface of the rack 802, and a second drive motor 804 that drives the slider 803 to move. The slider 803 is elastically slidably arranged on the upper surface of the fixed seat 801 along the length direction of the rack 802, and the rack 802 is elastically hinged on the upper surface of the slider 803. The second drive motor 804 is fixed on the surface of the fixed seat 801 by bolts, and the output end of the second drive motor 804 is connected to a connecting member that drives the slider 803 to reciprocate linearly along the length direction of the rack 802, wherein the connecting member is a cam, and the cam is horizontally arranged at one end of the slider 803, and the peripheral surface of the cam is in contact with the surface of the slider 803.

[0034] Combination Figure 6As shown, when the gear 2 to be measured is about to start to contact one end of the rack 802, the second drive motor 804 drives the cam to rotate and causes the slider 803 to reciprocate along the length direction of the rack 802, wherein the movement distance of the slider 803 is less than the tooth spacing of the gear 2 to be measured; when one of the tooth tops of the gear 2 to be measured is in contact with the rack 802, since the rack 802 reciprocates on the horizontal plane with the slider 803, the first tooth on the rack 802 close to the gear 2 to be measured has a greater probability of being located between the two tooth roots of the gear 2 to be measured. Compared with the previous fixed method, the meshing success rate between the rack 802 and the gear can be effectively improved, even if the rack 802 is not located between the two tooth roots of the gear 2 to be measured during the movement. During the movement, the rack 802 can also abut against the gear 2 to be measured and rotate it, thereby actively looking for a more suitable meshing angle (of course, during the process of the rack 802 abutting against the gear 2 to be measured, the rack 802 will deflect slightly in the horizontal plane, thereby reducing the impact force during the collision and protecting the integrity of the contact surface between the two), effectively improving the meshing speed of the gear 2 to be measured and the rack 802. As more gears 2 to be measured need to be detected, the accumulated time undergoes a qualitative change, which can effectively improve the efficiency of meshing degree detection; wherein, when the meshing of the gear 2 to be measured and the rack 802 is completed, the second drive motor 804 will stop moving, and the rack 802 will stop at a preset position, thereby ensuring the meshing stability between the subsequent gear 2 to be measured and the standard gear 6.

[0035] In this embodiment, the back side of the rack 802 is detachably connected to a vertical connecting plate 10 by bolts, and the connecting plate 10 is elastically hinged to the slider 803 and moves in a horizontal plane, and a vertical stopper 11 is fixed to the upper surface of the slider 803 by bolts, and the stopper 11 is arranged on a side away from the standard gear 6 and facing away from the rack 802, and the stopper 11 is spaced apart from the connecting plate 10, and a horizontally arranged arc block 12 is welded and fixed to the surface of one side of the connecting plate 10 close to the stopper 11, and one end of the arc block 12 away from the connecting plate 10 is elastically penetrated on the surface of the stopper 11, and one end of the arc block 12 penetrated on the connecting plate 10 is fixed with a limit block 16 abutting against the surface of the stopper 11, wherein the limit block 16 is arranged on the side away from the connecting plate 10, and a spring is sleeved on the outer surface of the arc block 12, and the two ends of the spring respectively abut against the surfaces of the connecting block and the stopper 11.

[0036] As shown in the figure, when the gear 2 to be tested moves toward the rack 802 and in the process of mutual meshing, when the two have a tooth-beating phenomenon, the rack 802 will deflect a small angle away from the gear 2 to be tested due to the impact force (combined with Figure 6As shown, the dotted line part represents the deflection angle of the rack 802), at this time, the corresponding spring is compressed and absorbs the impact force. Of course, the rack 802 also reciprocates along its length direction at the same time. When the gear 2 to be tested continues to move driven by the mobile platform 301, the gear 2 to be tested and the rack 802 then enter into a meshing state, and then the second drive motor 804 stops rotating. The rack 802 is also reset under the action of the spring and meshes with the gear 2 to be tested, which can effectively absorb the impact force when the gear 2 to be tested and the rack 802 are in a tooth-breaking situation, and reduce the damage to both, thereby ensuring the accuracy of the subsequent meshing degree detection of the gear 2 to be tested and the standard gear 6.

[0037] In this embodiment, a vertically arranged slot 13 is provided on the side surface of the rack 802 away from the standard gear 6, and a movable tooth 14 is detachably connected in the slot 13, and a gap is formed between the peripheral side surface of the movable tooth 14 and the slot 13, and an elastic connecting member is provided between the peripheral side surface of the movable tooth 14 and the slot 13, and the elastic connecting member is a spring, which is arranged in the gap (the specific arrangement method can be combined with Figure 7 As shown), and the two ends are respectively against the surfaces of the movable tooth 14 and the slot 13, and the peripheral side surface of the movable tooth 14 in contact with the gear to be measured 2 is covered with a flexible buffer material, such as silicone or rubber material.

[0038] Combination Figure 6 As shown, when the gear 2 to be measured is meshed with the rack 802, tooth hitting occurs. The flexible buffer material on the surface of the movable tooth 14 first contacts the gear 2 to be measured and effectively protects the collision surface of the two. Then the movable tooth 14 is squeezed and transmits its pressure to the corresponding spring. The spring contracts after being compressed. When the movable tooth 14 continues to squeeze the spring and abuts against the inner wall of the slot 13, the movable tooth 14 will drive the rack 802 to deflect a small angle. The spring arranged between the connecting plate 10 and the stopper 11 performs a second buffer, further absorbing and reducing the collision force between the gear 2 to be measured and the rack 802, which can effectively protect the measured gear and the rack 802, not only ensuring the integrity of the gear 2 to be measured, but also extending the service life of the rack 802 and the movable tooth 14.

[0039] In this embodiment, a positioning unit 15 corresponding to the gear 2 to be tested is provided on the upper surface of the operating table 1, and the positioning unit 15 includes a positioning plate 1501 which moves in the vertical direction and is placed horizontally, and a telescopic rod 1502 which drives the positioning plate 1501 to move vertically, the positioning plate 1501 is rotatably connected to the working end of the telescopic rod 1502, and the lower surface of the positioning plate 1501 is elastically slidably connected with a positioning ring 1503 which is coaxial with the positioning plate 1501 and moves in the vertical direction (a spring is provided between the positioning plate 1501 and the positioning ring 1503, which is not shown in the figure), and three positioning posts 1504 which are evenly spaced along a ring are fixed to the lower surface of the positioning ring 1503, and three positioning holes which match the positioning posts 1504 one by one are opened on the surface of each of the gears 2 to be tested.

[0040] When the gear 2 to be tested moves toward the standard gear 6 driven by the mobile platform 301 and meshes with it (the gear 2 to be tested and the rack 802 are no longer meshed), in other words, when the gear 2 to be tested moves to the detection station, the gear 2 to be tested is coaxial with the telescopic rod 1502, the positioning plate 1501 and the positioning ring 1503. At this time, the first drive motor 7 drives the standard gear 6 to rotate slowly, thereby indirectly driving the gear 2 to be tested to rotate. At the same time, the telescopic rod 1502 is started and drives the positioning plate 1501 to move vertically downward for a distance until the positioning column 1504 contacts the surface of the gear 2 to be tested, so that the positioning ring 1503 squeezes the spring and moves toward the positioning plate 1501. In this process, the slowly rotating gear 2 to be tested can Each positioning hole is able to cooperate with the corresponding positioning column 1504, and then the positioning ring 1503 abuts against the surface of the gear 2 to be tested and fixes it under the pressure of the spring, and the telescopic rod 1502 stops moving. At this time, the gear 2 to be tested is clamped between the positioning ring 1503 and the mobile platform 301 and is limited in the vertical direction, which can effectively ensure the stability of the gear 2 to be tested and the standard gear 6 when rotating at high speed, thereby improving the data accuracy during matching detection; when the matching detection is completed, the telescopic end of the telescopic rod 1502 moves vertically upward and resets, and the positioning ring 1503 and the positioning plate 1501 are away from the gear 2 to be tested. At this time, the mobile platform 301 can transport the gear 2 to be tested after the detection to the next workstation.

[0041] In this embodiment, the upper surface of the support platform 5 is provided with a fixing frame 17 for supporting the standard gear 6 (the shape of the fixing frame 17 is combined with the shape of the fixing frame 17). Figure 1As shown), the standard gear 6 and the first drive motor 7 are both mounted on the fixing frame 17 (of course, the standard gear 6 is also detachably connected to the fixing frame 17), the fixing frame 17 and the support platform 5 are detachably connected by bolts, and a plurality of bolt holes in a linear array facing the telescopic rod 1502 are provided on the upper surface of the support platform 5. The fixing frame 17 cooperates with different bolt holes to adjust the distance between the fixing frame 17 and the telescopic rod 1502. The rotating shaft 4 and the mobile platform 301 are also detachably connected by bolts, and bolt holes in a linear array are also provided on the upper surface of the mobile platform 301 (only some of the bolt holes are shown on the surfaces of the support platform 5 and the mobile platform 301 in the figure). By cooperating with different bolt holes, the fixed position of the rotating shaft 4 between the mobile platform 301 on the horizontal plane can be adjusted.

[0042] When it is necessary to perform matching detection on gears 2 to be tested of different sizes, it is of course necessary to replace the standard gear 6 that matches the gear 2 to be tested. Therefore, it is necessary to compensate for the spacing between the two gears of different sizes when they are meshing. By removing the bolts and moving the fixing frame 17 on the horizontal plane, the distance between the standard gear 6 and the telescopic rod 1502 is adjusted, so as to adjust the position of the standard gears 6 of different sizes. At the same time, by removing the bolts and moving the position of the rotating shaft 4 on the mobile platform 301 horizontally, the meshing position of the standard gear 6 and the gear 2 to be tested is always guaranteed to remain unchanged and within the optimal detection position of the detection unit 9; it can meet the matching detection of gears of various sizes, and effectively improve the scope of application and work efficiency of the present invention.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
