Description

Technical Field

[0001] The present invention relates to the technical field of gear detection, and specifically provides a precision detection device for gear processing. Background Art

[0002] Gear processing is a precise and complex manufacturing process, and its quality directly affects the transmission performance and operation stability of mechanical equipment. At the initial stage of gear processing, it is necessary to carefully select appropriate blank materials, such as steel, according to the specific use and performance requirements of the gear, and make the blank through forging or casting. In the whole processing process, accurate control of processing accuracy, reasonable selection and wear management of cutting tools, optimized setting of process parameters, and appropriate selection of reference and clamping methods are all key factors to ensure the quality of gear processing. Finally, only the gears that pass strict inspection can be put into use to provide reliable guarantee for the stable operation of various mechanical equipment.

[0003] In modern manufacturing, gears are key components for transmitting power and motion in various mechanical equipment, and their processing accuracy plays a decisive role in the operation performance, reliability and service life of the equipment. With the rapid development of high-end manufacturing industries such as aerospace, automotive, and precision instruments, the accuracy requirements for gears are getting higher and higher, and the importance of gear processing accuracy detection is becoming increasingly prominent. The processing accuracy of gears covers multiple aspects, including tooth profile accuracy, pitch accuracy, helix angle accuracy, tooth surface roughness, etc. In order to ensure that gears can meet the design and use requirements, it is necessary to use high-precision detection devices to accurately measure their various accuracy indicators.

[0004] The prior art with the publication number of CN119618064A provides a precision detection device for gear processing, which is applicable to the dynamic performance and single-tooth accuracy detection of gears. The device includes a base, a rotating bracket, a fixed block, a motor, a reduction gearbox, a test gear, a gear to be tested, a main measuring rod and multiple measuring rods, etc. Through the structural design of fiber Bragg grating, grating ruler and auxiliary rod, high-precision detection of gear dynamic balance, vibration parameters and the outer end and contour line of a single gear tooth is realized. The reduction gearbox reduces the gear speed and enhances torque control. Combined with the gear thickness difference design, multiple measuring rods can slide along the outer end of the gear tooth to accurately detect the tooth surface deformation and contact state. The device is made of high-carbon low-alloy tool steel, has high strength and wear resistance, adapts to various gear specifications, can output detection data and analysis results in real time, is easy to operate, has high detection accuracy and strong applicability, and can be widely used in the fields of gear manufacturing, quality inspection and maintenance.

[0005] Although the prior art can carry out dynamic balance detection on gears, there are obvious deficiencies. On the one hand, it only uses a single probe to detect gears, resulting in slow detection speed and extremely low detection efficiency. On the other hand, in actual detection scenarios, the types of gears to be detected are rich and diverse, covering spur gears and special-shaped gears such as bevel gears, helical gears, double helical gears, and double helical gears. For gears with a double-tooth structure like double helical gears, the moving path of the detection head in the existing detection device is difficult to meet the detection requirements, and it cannot accurately and comprehensively detect them.

[0006] It can be seen that a precision detection device for gear processing is needed to solve the problems of low detection efficiency of the existing device using a single probe and the fixed moving path of the probe detection being unable to meet the double-tooth detection requirements mentioned in the above background technology.

The lifting rod is located outside the first lead screw, and the bottom of the lifting rod is connected to the collecting plate.

[0012] Preferably, the number of the detection probes, rotating blocks, rotating cages, limiting blocks and outer sleeve rods is multiple groups, which are arranged in a circular shape at the lower part inside the collecting plate.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 4 , a precision detection device for gear processing, including an assembly 1, and a lifting component 2 for controlling the lifting of the assembly 1 is installed above the assembly 1.

[0024] In this embodiment, the lifting assembly 2 is generally not installed separately, but is installed together with the displacement platform. The displacement platform can drive the lifting assembly 2 to perform lateral and longitudinal displacements. The displacements in two directions can drive the detection probe 305 to move anywhere, so that the gear can be detected more flexibly. No matter where the gear is fixed on the plane, it can be detected. The displacement platform is a prior art and will not be elaborated here. In the case where the detection base is fixed, the detection probe 305 generally does not need to move over a large range. Therefore, only the lifting assembly 2 is specifically mentioned in this case. A fixed vertical plate is installed at the rear of the lifting assembly 2 to provide support for the installation of the assembly 1 and the lifting assembly 2. The detection base is located below the double-tooth gear 5 and is fixed through the hollow part inside the double-tooth gear 5.

[0025] Specifically, the assembly 1 includes a collecting plate 101 and limiting grooves 102. The number of the limiting grooves 102 is multiple groups. Multiple groups of limiting grooves 102 are equidistantly opened below the inside of the collecting plate 101, and multiple groups of limiting grooves 102 are penetrated by the outer sleeve rod 301 and the rotating block 304.

[0026] In this embodiment, an installation bin is arranged below the collecting plate 101, and parts such as the displacement and rotation assembly 3 and the adjustment assembly 4 can be installed inside it, providing installation space and support for the parts in the displacement and rotation assembly 3 and the adjustment assembly 4. In this embodiment, the number of the limiting grooves 102 is set to six groups, and the actual number can be adjusted according to the on-site use situation, such as eight groups, twelve groups, etc. Correspondingly, the numbers of the detection probe 305, the rotating block 304, the rotating cage 303, the limiting block 302, and the outer sleeve rod 301 also need to be changed accordingly.

[0027] Specifically, the lifting assembly 2 includes a rotating motor 201, and the output end of the rotating motor 201 is connected with a small pulley 202. One side of the small pulley 202 is connected with a large pulley 203 through a belt, and a central part 204 is arranged at the middle position inside the large pulley 203. Both sides below the large pulley 203 are connected with telescopic sleeves 210, and one end of the telescopic sleeve 210 is connected to the collecting plate 101.

[0028] In this embodiment, the rotating motor 201 can be a servo motor, which rotates at a certain angle after starting, or a controller can be additionally installed to control its rotation speed and rotation angle. After the rotating motor 201 is started, it will drive the large pulley 203 to rotate through the small pulley 202. The large pulley 203 drives the assembly 1 to rotate through two telescopic sleeves 210. When the assembly 1 rotates at a certain angle, the detection position of the detection probe 305 can be changed. Additionally, infrared sensors can be installed on the detection base and the bottom end of the rotating gear 401. When the rotating motor 201 is started, the calibration purpose can be achieved through the cooperation of the infrared sensors to check whether the device is in the correct position.

[0029] Specifically, a through hole is provided inside the central member 204, and a first lead screw 205 is arranged inside the through hole. The top end of the first lead screw 205 is connected to a first bevel gear set 208, and a lifting motor 209 is installed on one side of the first bevel gear set 208. A first moving block 206 is arranged on the outer side of the first lead screw 205, and the first moving block 206 is connected to a lifting rod 207. The lifting rod 207 is located on the outer side of the first lead screw 205, and the bottom of the lifting rod 207 is connected to the collecting plate 101.

[0030] In this embodiment, a bearing is arranged in the through hole inside the large pulley 203 and is connected to the central member 204 through the bearing. When the large pulley 203 rotates, the internal central member 204 will not rotate under the action of the bearing. The central member 204 includes a top disc portion, two side support rods and a lower sleeve portion. The top disc portion is located inside the large pulley 203. The two side support rods are connected to the lower sleeve portion, and the two side support rods are located at the bottom end of the top disc portion. The lower sleeve is sleeved with the lifting rod 207. Therefore, when the lifting rod 207 moves up and down, the central member 204 will also remain stationary. The first bevel gear set 208 includes two sets of meshing bevel gears, one of which is connected to the lifting motor 209. When the lifting motor 209 drives one set of bevel gears to rotate, the other set of bevel gears will also rotate.

[0031] Please refer to Figures 5 - 8 , a precision detection device for gear processing, and a displacement rotation assembly 3 is installed inside the assembly part 1. The displacement rotation assembly 3 includes a plurality of detection probes 305 arranged at equal intervals in a circular shape. A double-tooth gear 5 to be detected is installed on one side of the bottom end of the detection probe 305, and the top end of the detection probe 305 is connected to a rotating block 304. One side of the rotating block 304 is connected to an outer sleeve rod 301, and a limiting block 302 is connected below one end of the outer sleeve rod 301. A rotating cage 303 is arranged at one end of the outer sleeve rod 301. The limiting block 302 is located in a rotating groove 307, and the rotating groove 307 is arranged inside a large gear 306. A small gear 308 meshing with the large gear 306 is arranged on one side of the large gear 306. The limiting block 302 is penetrated by a pin tooth 311, and the pin tooth 311 is arranged on a rotating disc 310.

[0032] In this embodiment, a controller is installed in the device, and the controller is electrically connected to the electronic components in the device to facilitate direct control of the device startup. In this embodiment, the number of rotating grooves 307 and the number of detection probes 305 are matched. The purpose of rotating the large gear 306 is to cause the rotating groove 307 to move. The displacement of the spiral rotating groove 307 will directly drive the limit block 302 to move, so that the outer sleeve rod 301 moves inside the limit groove 102, and then the multiple groups of detection probes 305 have the same movement, approach together, or move away together. The multiple groups of detection probes 305 are distributed in a circle, the same shape as the gear to be tested, and will merge into a small circle when they are close together, and move away together. It will expand into a large circle, so that it can flexibly cooperate with gears of different sizes to be tested for testing, and by rotating the pin teeth 311, the rotating cage 303 will also be driven to rotate. The rotating cage 303 and the pin teeth 311 are actually a cage gear structure. The rotating cage 303 is two upper and lower disks, and the middle circumferentially equidistantly filled cage columns. The teeth of the pin teeth 311 cooperate with the cage columns. The rotating cage 303 can be driven to rotate by rotating the pin teeth 311. The rotating cage 303 has multiple groups, which are distributed in a circle on the top of the pin teeth 311. Due to the matching structure of the cage gear, the rotating cage 303 can still maintain contact and matching with the pin teeth 311 even if it moves a certain distance. Therefore, when the outer rod 301 drives the rotating cage 303 to move, the matching relationship between them is not affected.

[0033] Specifically, there are multiple groups of detection probes 305, rotating blocks 304, rotating cages 303, limit blocks 302 and outer rods 301, which are arranged in a circle at the bottom of the collecting plate 101. One end of the rotating cage 303 is connected to a rotating shaft 3031, and the rotating shaft 3031 passes through the outer rod 301 and is connected to the rotating block 304. A bearing is arranged between the end of the outer rod 301 and the rotating cage 303. There are multiple groups of rotating grooves 307, and the multiple groups of rotating grooves 307 are equidistantly distributed in a spiral shape inside the large gear 306. The limit blocks 302 move inside the rotating grooves 307, and a displacement motor 309 is installed below the small gear 308.

[0034] In this embodiment, the rotation of the rotating disk 310 will drive the pin teeth 311 to rotate. The pin teeth 311 penetrate the large gear 306 and extend above it to contact the rotating cage 303. After the rotating cage 303 is turned, it will drive the rotating shaft 3031 to rotate, thereby driving the rotating block 304 and the detection probe 305 to rotate. The rotation angle of the detection probe 305 is coordinated with the inclination angle of the double-tooth gear 5, so the detection probe 305 can be driven to tilt from top to bottom in coordination with the lifting of the lifting assembly 2 to detect the bevel angle of the double-tooth gear 5. The detection probe 305 can use a scanning probe or a laser probe.

[0035] Specifically, a through hole is provided inside the large gear 306, and a rotating disk 310 is arranged below the large gear 306. The number of pin teeth 311 is multiple groups, which are equidistantly distributed in a circular shape at the center of the rotating disk 310. The pin teeth 311 penetrate through the large gear 306 and extend into the tooth gaps of the rotating cage 303. The bottom end of the rotating disk 310 is connected to a rotating gear 401.

[0036] In this embodiment, the large gear 306 is only driven to rotate by the small gear 308. A bearing can be installed between the lower part of the large gear 306 and the rotating disk 310. The bearing provides support for the large gear 306, and the large gear 306 will not rotate when the rotating disk 310 rotates.

[0037] Please refer to Figures 9 - 11 , a precision detection device for gear processing. A regulating component 4 is arranged below the displacement rotating component 3. The regulating component 4 includes a rotating gear 401, and a rack plate 402 meshing with the rotating gear 401 is connected to the rear side of the rotating gear 401. One end of the rack plate 402 is connected to a second connecting plate 405 through a first connecting plate 403 and a hinge plate 406. The bottom end of the second connecting plate 405 is hinged to a hinge connecting rod 409 and a central hammer 410 through an extension shaft 408. Eccentric hammers 411 are arranged on both sides of the central hammer 410. The central hammer 410 and the eccentric hammers 411 are both penetrated by a penetrating shaft 412. The inner side of the hinge connecting rod 409 is hinged to a connecting rod 414, and one end of the connecting rod 414 is hinged to a threaded block 415. A second moving block 416 is arranged at the rear side of the threaded block 415. The threaded block 415 moves in a sector-shaped groove 417. The threaded block 415 is penetrated by a second lead screw 418, and the top end of the second lead screw 418 is connected to a second bevel gear set 419.

[0038] In this embodiment, the fixed back plate 404 is fixed in the installation bin. Both ends of the fixed back plate 404 are not sealed. The second connecting plate 405 and the first connecting plate 403 both move inside the fixed back plate 404. The rack plate 402 also moves inside the fixed back plate 404. When the rack plate 402 moves, it contacts the rotating gear 401 and thus drives the rotating gear 401 to rotate. The moving amplitude of the rack plate 402 can be adjusted, so the rotating amplitude of the rotating gear 401 can be adjusted. The larger the rotation angle of the rotating gear 401, the larger the rotation amplitude of the rotating cage 303, and thus the larger the rotation angle of the detection probe 305.

[0039] Specifically, a fixed back plate 404 is installed at the rear side of the rack plate 402, and a vertical chute is provided inside the fixed back plate 404. One end of the rack plate 402 is connected to a first connecting plate 403, and one end of the first connecting plate 403 is hinged to a hinged plate 406. The other end of the hinged plate 406 is hinged to a second connecting plate 405, and the second connecting plate 405 is located in the vertical chute. A positioning plate 407 is provided inside the fixed back plate 404, and the other end of the positioning plate 407 is hinged to the center position of the hinged plate 406.

[0040] In this embodiment, the vertical chute includes a longitudinal portion and a transverse portion, which are connected at the end. The second connecting plate 405 moves in the longitudinal portion, and the first connecting plate 403 moves in the transverse portion. One end of the positioning plate 407 is positioned inside the fixed back plate 404. The second connecting plate 405 is lifted and lowered by the up-and-down swing of the extension shaft 408. The lifting and lowering of the second connecting plate 405 will drive the first connecting plate 403 to move left and right reciprocally through the hinged plate 406 and the positioning plate 407, thereby driving the rack plate 402 to move reciprocally.

[0041] Specifically, the second connecting plate 405 is hinged to the extension shaft 408, and the extension shaft 408 penetrates through the fixed back plate 404 and extends to the outside thereof. Circular holes are provided inside the center hammer 410 and the eccentric hammer 411, and the circular holes are matched with the through shaft 412. One end of the through shaft 412 is provided with a driving motor 413.

[0042] In this embodiment, the adjustment process includes rotating the handle on one side of the second bevel gear set 419 to rotate one set of bevel gears, thereby driving the other set of bevel gears meshing with it to rotate, and then driving the second lead screw 418 to rotate. The rotation of the second lead screw 418 will drive the threaded block 415 to descend, and then the second moving block 416 will move along the inner side of the sector groove 417, moving from the higher end of the sector groove 417 to the lower end. The end of the connecting rod 414 hinged to the articulated connecting rod 409 will displace, and then the swing amplitude of the extension shaft 408 that swings following the rotation of the through shaft 412 will increase, so that the lifting and lowering amplitude of the second connecting plate 405 will increase, the reciprocating movement amplitude of the rack plate 402 will increase, and the rotation amplitude of the rotating gear 401 will increase.

[0043] Specifically, the second bevel gear set 419 includes two sets of meshing bevel gears, a cage, a handle, and a fixed block. The cage is arranged between the two sets of meshing bevel gears. One of the bevel gears is internally connected through a shaft, and the shaft penetrates through the fixed block at the same time. One end of the shaft is connected to the handle.

[0044] In this embodiment, a motor can be installed on the rear side of the handle, or the handle can be driven manually. When the handle is rotated to change the position of the second moving block 416, the second screw rod 418 tilts as a whole, thereby driving a group of bevel gears connected to the second screw rod 418 to revolve around another group of bevel gears.

[0045] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the gear to be tested is placed on a fixed seat and waits for testing. Then, the positions of multiple groups of detection probes 305 can be adjusted according to the diameter of the gear to be tested, and the displacement motor 309 is started. The displacement motor 309 drives the small gear 308 to rotate. The rotation of the small gear 308 drives the large gear 306 to rotate through meshing. The rotation of the large gear 306 changes the position of the rotating groove 307, thereby limiting the limit block 302, so that the limit block 302 is displaced. The limit block 302 drives the rotating block 304 and the detection probe 305 to be displaced through the outer sleeve rod 301, so that the multiple groups of detection probes 305 distributed in a circle are expanded outward or contracted inward together. The probe stops rotating when it is close to the teeth of the double-toothed gear 5. After the position is adjusted, the lifting motor 209 can be started, so that the lifting motor 209 drives the first bevel gear set 208 to rotate, and the first bevel gear set 208 drives the first screw rod 205 to rotate, thereby driving the first moving block 206 to descend, and the first moving block 206 drives the lifting rod 207 to descend, so that the position of the assembly 1 is lowered, so that the position of the detection probe 305 is lowered and close to the gear to be tested, and the detection probe 305 can detect the gear to be tested; If it is a helical gear or a double helical gear, the drive motor 413 can be started, so that the drive motor 413 drives the through shaft 412 to rotate, thereby driving the second connecting plate 405 to move up and down through the central hammer 410, the hinge connecting rod 409 and the extension shaft 408. The lifting action of the second connecting plate 405 is transmitted to the first connecting plate 403 through the hinge plate 406 and the positioning plate 407, so that the rack plate 402 moves back and forth, thereby driving the rotating gear 401 meshed on one side thereof to rotate back and forth, and the rotation of the rotating gear 401 drives the rotating disk 31 0 rotates, the rotation of the rotating disk 310 will move the rotating cage 303 through the pin teeth 311, so that the multiple groups of rotating cages 303 rotate synchronously, and then drive the rotating block 304 and the detection probe 305 to rotate through the rotating shaft 3031, and the detection probe 305 rotates and cooperates with the descending action to detect the helical teeth of the double-tooth gear 5 from top to bottom. Since the reciprocating rotation of the rack plate 402 will drive the rotating gear 401 to rotate forward and reverse, the detection probe 305 will rotate and tilt in the opposite direction when it tilts to a certain angle, meeting the detection requirements of the double-helical gear; After a set of teeth has been detected, the position of the detection probe 305 rises, and the rotation motor 201 drives the large pulley 203 to rotate once through the small pulley 202, thereby driving the assembly 1 to rotate once through the telescopic sleeve 210, and then changing the position of the detection probe 305 to make the detection probe 305 rotate around the teeth for detecting the next set of teeth.
