Description

Technical Field

[0001] The present invention relates to the field of gear chamfer measurement, and specifically to a gear chamfer laser measuring instrument. Background Art

[0002] A gear chamfer laser measuring instrument is a device used to measure the profile dimensions of gear chamfers, mainly applied to the measurement of the profile dimensions and geometric tolerances of the end chamfers of internal and external gears. Such a measuring instrument generally includes a tooth profile positioning component, a rotating work platform, a profile measuring device, a data acquisition and processing device, etc. The gear to be measured is placed on the rotating work platform, the tooth profile positioning component fixes the gear, the profile measuring device detects the position and size of the gear chamfer, and transmits the data to the data acquisition and processing device through a data line.

[0003] For example, the gear chamfer laser measuring instrument disclosed in Chinese Patent CN102322819B adopts a non-contact measurement method, with advantages such as visualization, intelligence, high sampling rate, high precision, and non-destructive measurement. It uses a tooth profile positioning component to achieve accurate positioning of the gear to be measured. The measured value of the laser displacement sensor can be directly used as the Z-direction coordinate value of each measurement point on the scanned section, avoiding system calibration errors, significantly improving the measurement accuracy, and can automatically search for the center of the gear to be measured and realize multi-section continuous measurement of the gear chamfer profile with this center as the reference; the driving method uses a two-dimensional motion method to replace the traditional one-dimensional motion method, which can achieve one-time multi-section measurement of the gear chamfer, and the positioning of each section and the measurement starting point is accurate, eliminating the influence of human factors on the measurement result, with a relatively high degree of intelligence and automation. One computer can synchronously perform tasks such as synchronous control, data acquisition, and data processing; high-precision laser displacement sensors are used to collect data, effectively improving the detection accuracy of the instrument.

[0004] For this structure, although it can measure the gear chamfer, when there is a lot of dust in the surrounding environment, and this measurement structure cannot clean the dust in the surrounding environment. Subsequently, the laser measuring instrument will perform measurement work in an environment with a lot of dust. Since the laser measuring instrument is sensitive to environmental conditions during use, this will cause dust to affect the optical measurement accuracy of the laser measuring instrument, and then affect the use of the laser measuring instrument. Therefore, we propose a gear chamfer laser measuring instrument that can clean dust to improve the measurement accuracy. Summary of the Invention

[0005] The purpose of the present invention is to provide a gear chamfer laser measuring instrument to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a gear chamfer laser measuring instrument, including a processing table, on the outer wall of which a control panel is fixedly installed. Above the processing table, there is a gear body, and a processing component arranged outside the gear body. The processing component includes a protection component arranged above the processing table, a fixing component arranged below the protection component, and a measuring component arranged above the fixing component.

[0007] According to the above technical solution, the protection component includes a bracket fixedly installed on the top surface of the processing table. Inside the bracket, a telescopic rod is fixedly installed. At the end of the telescopic rod, a push plate is fixedly installed. One end of the outer wall of the push plate is hinged with a first connecting plate. The end of the first connecting plate away from the push plate is hinged with a moving frame. On the outer wall of the moving frame, an observation window is fixedly installed. On the side wall of the moving frame, a sealing frame is fixedly installed. On the outer wall of the sealing frame, a fixing frame is slidably arranged. Inside the fixing frame, a pipe groove is communicated. At the end of the pipe groove, a connecting pipe is communicated. The end of the connecting pipe away from the pipe groove is communicated with an air plate. On the outer wall of the air plate, air nozzles are communicated. Inside the fixing frame, an elastic groove is opened. Inside the elastic groove, an elastic sheet is fixedly installed. Inside the fixing frame, a clamping frame is fixedly installed. Inside the clamping frame, an adsorption plate is slidably arranged.

[0008] According to the above technical solution, the fixing component includes a screw rod rotatably connected to the bottom of the processing table. A sleeve block is sleeved on the outer wall of the screw rod. One end of the outer wall of the sleeve block is hinged with a second connecting plate. The end of the second connecting plate away from the sleeve block is hinged with a slider. At the end of the slider away from the second connecting plate, a clamping rod is fixedly installed. On the top surface of the processing table, a sliding groove is opened.

[0009] According to the above technical solution, the measuring component includes a mounting plate fixedly installed at the bottom of the push plate. At the bottom of the mounting plate, a motor is fixedly installed. At the output end of the motor, a rotating rod is fixedly installed. On the outer wall of the rotating rod, a first magnetic ring is fixedly installed. Inside the first magnetic ring, a clamping rod is sleeved. At the end of the clamping rod, a second magnetic ring is fixedly installed. Inside the rotating rod, a connecting block is hinged. On the outer wall of the connecting block, a clamping hole is opened. On the outer wall of the connecting block, a laser measuring instrument body is fixedly installed.

[0010] According to the above technical solution, the outer wall of the sealing frame and the inside of the fixing frame are hermetically slidable, and the fixing frame is fixedly installed on the top surface of the processing table. When the first connecting plate pulls the moving frame, the moving frame drives the sealing frame to slide outwards from the fixing frame, and air is sucked into the inside of the fixing frame.

[0011] According to the above technical solution, the number of the moving frames and the fixing frames is two groups, symmetrically distributed along the center line of the top surface of the processing table. Under the protection of the moving frames and the fixing frames, the influence of external dust on the measurement of the laser measuring instrument body can be avoided.

[0012] According to the above technical solution, a frame groove is provided inside the fixed frame. The fixed frame is communicated with a connecting pipe through a pipe groove, and the connecting pipe is communicated with an air head through an air plate. The adsorption plate is made of an adsorption material. When the air head and the adsorption plate are used in cooperation, dust in the measurement environment can be cleaned to improve the measurement accuracy.

[0013] According to the above technical solution, the outer wall of the clamping rod is made of a flexible material. There are six clamping rods, which are distributed circumferentially around the center of the sleeve block. Under the restriction of the clamping rods arranged on the outer wall of the flexible material, the inner side of the gear body can be prevented from being scratched. The clamping rods made of flexible material will not affect the clamping accuracy and stability of the gear body. The six converging clamping rods can release the clamping of the gear body to replace the measured gear body.

[0014] According to the above technical solution, the outer wall of the slider is slidably arranged inside the chute, and the sleeve block is threadedly sleeved on the outer wall of the screw rod. Under the restriction of the second connecting plate and the slider, the rotating screw rod can drive the sleeve block sleeved on its outer wall to move up and down.

[0015] According to the above technical solution, the first magnetic ring and the second magnetic ring are magnetically attracted to each other, and the clamping rod is clamped with the clamping hole. Under their restriction, the measurement angle of the laser measuring instrument body can be adjusted.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The gear chamfer laser measuring instrument of the present invention includes a protection component as one of its parts. When measuring the gear body, it needs to be fixed on the top surface of the processing table through a fixing component and then measured by a measuring component. When there is a lot of dust in the surrounding environment, the dust will affect the optical measurement accuracy of the laser measuring instrument, thereby affecting the use of the laser measuring instrument. Therefore, it is necessary to deal with the dust outside the gear body. After the gear body is fixed, the telescopic rod is started, and it pushes the push plate downward. Since the end of the first connecting plate is hinged to the push plate and the moving frame, and the fixed frame is fixedly installed on the top surface of the processing table, under its restriction, the downward-moving push plate pulls the moving frame through the first connecting plate, causing the moving frame to slide inside the fixed frame. Since the sealing frame fixedly installed at the end of the moving frame seals and slides inside the fixed frame, under its restriction, the sealing frame pumps the gas inside the fixed frame, sucks air through the pipe groove into the connecting pipe and the air plate, and the air heads communicated with the air plate suck the air inside the moving frame and the inner side of the fixed frame, sucking the floating dust into the air heads, the air plate, the connecting pipe and the pipe groove, and at the same time collecting and treating the dust attached to the outer wall of the gear body. When the two moving frames come into contact with each other and no longer slide, the air heads no longer perform the dust suction work, avoiding the influence of the air flow inside the two moving frames and the fixed frame on the measurement of the laser measuring instrument body. When the push plate moves downward, it drives the measuring component to move downward accordingly, and the gear body can be measured through the measuring component. After the measurement is completed, the telescopic rod drives the push plate to move upward, and the moving frame is pushed through the first connecting plate, causing the moving frame to drive the sealing frame to slide into the fixed frame, discharging the dust-containing gas inside it. At this time, even if there is dust on the outer wall of the gear body, it does not affect the taking and placing of the gear body.

[0017] 2. The gear chamfer laser measuring instrument of the present invention includes a protection component as one of its parts. When the moving frame drives the sealing frame to slide into the fixed frame, it sucks the dust inside the fixed frame and the moving frame through the air heads. The air drives the dust to flow, and part of the dust is adsorbed on the outer wall of the adsorption plate. In cooperation with the air heads, the adsorption plate can perform dust removal treatment inside the moving frame and the fixed frame, enabling the laser measuring instrument body to measure accurately. When the adsorption plate has been used for a long time and needs to be replaced, press the elastic piece to make the elastic piece move into the elastic groove. At this time, pull the adsorption plate to replace the adsorption plate. This structure cooperates with the adsorption plate and the air heads to remove dust outside the gear body. Since the adsorption plate can be replaced conveniently, it is more convenient to use.

[0018] 3. The gear chamfer laser measuring instrument of the present invention has a fixing component as one of its parts. When measuring the gear body, it needs to be fixed. The inner center of the gear body is sleeved outside the clamping rod. Rotate the screw. Since the sleeve block is hinged to the slider through the second connecting plate, and the slider is slidably arranged inside the chute, under its restriction, the rotating screw can drive the sleeve block sleeved on its outer wall to move upward. The sleeve block pushes the slider through the second connecting plate, so that the slider drives the clamping rod to move. The six clamping rods move in an open manner to support the inside of the gear body. This structure can automatically position the center of the gear body, without the need for the operator to manually adjust the position of the center of the gear body, and this structure can quickly fix the gear body, improving the convenience of measurement.

[0019] 4. The gear chamfer laser measuring instrument of the present invention has a measuring component as one of its parts. When it is necessary to measure the gear body, start the laser measuring instrument body and perform the measurement work in cooperation with the control panel. When it is necessary to adjust the measurement angle, start the motor, and the rotating rod fixedly installed at its output end rotates accordingly. The rotating rod drives the connecting block hinged inside it to rotate, and the connecting block drives the laser measuring instrument body to rotate accordingly to rotate and adjust the measurement angle. When it is necessary to measure the side part, pull out the clamping rod and rotate the laser measuring instrument body and the connecting block so that the connecting block rotates with the hinge point with the rotating rod as the center of rotation. After the angle adjustment is completed, insert the clamping rod into the rotating rod and the card hole. Under the magnetic attraction restriction of the first magnetic ring and the second magnetic ring, it can prevent the clamping rod from falling off the rotating rod. This structure can flexibly adjust the measurement angle to obtain more measurement data. Description of the Drawings

Specific implementation manner

[0021] 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.

[0022] Embodiment 1: A preferred embodiment of a gear chamfer laser measuring instrument provided by the present invention is as Figures 1 to 9 shown: A gear chamfer laser measuring instrument includes a processing table 1; A control panel 2 is fixedly installed on the outer wall of the processing table 1; A gear body 3 is arranged above the processing table 1; and a processing component 4 arranged outside the gear body 3. The processing component 4 includes a protection component 41 arranged above the processing table 1. The protection component 41 includes a bracket 411 fixedly installed on the top surface of the processing table 1. A telescopic rod 412 is fixedly installed inside the bracket 411. A push plate 413 is fixedly installed at the end of the telescopic rod 412. A first connecting plate 414 is hinged to the outer wall of the push plate 413. One end of the first connecting plate 414 away from the push plate 413 is hinged to a moving frame 415. An observation window 416 is fixedly installed on the outer wall of the moving frame 415. A sealing frame 417 is fixedly installed on the side wall of the moving frame 415. A fixed frame 418 is slidably arranged on the outer wall of the sealing frame 417. A pipe groove 419 is communicated and arranged inside the fixed frame 418. A connecting pipe 420 is communicated and arranged at the end of the pipe groove 419. One end of the connecting pipe 420 away from the pipe groove 419 is communicated and arranged with an air plate 421. An air nozzle 422 is communicated and arranged on the outer wall of the air plate 421. An elastic groove 423 is opened on the inner side of the fixed frame 418. An elastic piece 424 is fixedly installed inside the elastic groove 423. A clamping frame 425 is fixedly installed on the inner side of the fixed frame 418. An adsorption plate 426 is slidably arranged inside the clamping frame 425.

[0023] In this embodiment, when measuring the gear body 3, it needs to be fixed on the top surface of the processing table 1 through the fixing component 43, and then measured by the measuring component 44. When there is a lot of dust in the surrounding environment, the dust will affect the optical measurement accuracy of the laser measuring instrument, and then affect the use of the laser measuring instrument. Therefore, it is necessary to deal with the dust outside the gear body 3. After the gear body 3 is fixed, the telescopic rod 412 is started, which pushes the push plate 413 downward. Since the end of the first connecting plate 414 is hinged to the push plate 413 and the moving frame 415, and the fixed frame 418 is fixedly installed on the top surface of the processing table 1, under its restriction, the downward moving push plate 413 pulls the moving frame 415 through the first connecting plate 414, so that the moving frame 415 slides inside the fixed frame 418. Since the sealing frame 417 fixedly installed at the end of the moving frame 415 seals and slides inside the fixed frame 418, under its restriction, the sealing frame 417 pumps the gas inside the fixed frame 418, sucks air through the pipe groove 419 into the connecting pipe 420 and the air plate 421, and the air head 422 communicated with the air plate 421 sucks the air inside the moving frame 415 and the inner side of the fixed frame 418, sucking the floating dust into the air head 422, the air plate 421, the connecting pipe 420 and the pipe groove 419, and at the same time collecting and processing the dust attached to the outer wall of the gear body 3. When the two moving frames 415 come into contact with each other, they no longer slide, and the air head 422 no longer performs the dust suction work, avoiding the air flow inside the two moving frames 415 and the fixed frame 418 from affecting the measurement of the laser measuring instrument body 449. When the push plate 413 moves downward, it drives the measuring component 44 to move downward accordingly, and then the gear body 3 can be measured by the measuring component 44. After the measurement is completed, the telescopic rod 412 drives the push plate 413 to move upward, pushes the moving frame 415 through the first connecting plate 414, and makes the moving frame 415 drive the sealing frame 417 to slide into the fixed frame 418, discharging the dust-containing gas inside it. At this time, even if there is dust on the outer wall of the gear body 3, it does not affect the taking and placing of the gear body 3. When the moving frame 415 drives the sealing frame 417 to slide into the fixed frame 418, it sucks the dust inside the fixed frame 418 and the moving frame 415 through the air head 422, and the air drives the dust to flow. Part of the dust is adsorbed on the outer wall of the adsorption plate 426. With the cooperation of the adsorption plate 426 and the air head 422, the inside of the moving frame 415 and the fixed frame 418 can be dust-removed, so that the laser measuring instrument body 449 can accurately measure. When the adsorption plate 426 has been used for a long time, it needs to be replaced. Press the elastic piece 424 to make the elastic piece 424 move into the elastic groove 423. At this time, pull the adsorption plate 426 to replace the adsorption plate 426. This structure removes dust from the outside of the gear body 3 through the mutual cooperation of the adsorption plate 426 and the air head 422. Since the adsorption plate 426 can be conveniently replaced, it is easier to use.

[0024] Embodiment 2: The preferred embodiment of a gear chamfer laser measuring instrument provided by the present invention is as Figures 1 to 9As shown in the figure: The fixing component 43 includes a screw rod 431 rotatably connected to the bottom of the processing table 1. A sleeve block 432 is sleeved on the outer wall of the screw rod 431. A second connecting plate 433 is hinged to the outer wall of the sleeve block 432. One end of the second connecting plate 433 away from the sleeve block 432 is hinged to a slider 434. A clamping rod 435 is fixedly installed at one end of the slider 434 away from the second connecting plate 433. A chute 436 is formed on the top surface of the processing table 1.

[0025] In this embodiment, when measuring the gear body 3, it needs to be fixed. The inner center of the gear body 3 is sleeved outside the clamping rod 435. Rotate the screw rod 431. Since the sleeve block 432 is hinged to the slider 434 through the second connecting plate 433, and the slider 434 is slidably arranged inside the chute 436, under its restriction, the rotating screw rod 431 can drive the sleeve block 432 sleeved on its outer wall to move upward. The sleeve block 432 pushes the slider 434 through the second connecting plate 433, so that the slider 434 drives the clamping rod 435 to move. The six clamping rods 435 move in an opening manner to support the inside of the gear body 3. This structure can automatically position the center of the gear body 3, without the need for the operator to manually adjust the position of the center of the gear body 3, and this structure can quickly fix the gear body 3, improving the convenience of measurement.

[0026] Embodiment 3: A preferred embodiment of the gear chamfer laser measuring instrument provided by the present invention is as Figures 1 to 9 As shown in the figure: The measuring component 44 includes a mounting plate 441 fixedly installed at the bottom of the push plate 413.

A first magnetic ring 444 is fixedly installed on the outer wall of the rotating rod 443. A clamping rod 445 is sleeved inside the first magnetic ring 444. A second magnetic ring 446 is fixedly installed at the end of the clamping rod 445. A connecting block 447 is hinged inside the rotating rod 443. A clamping hole 448 is formed on the outer wall of the connecting block 447. A laser measuring instrument body 449 is fixedly installed on the outer wall of the connecting block 447.

[0027] In this embodiment, when it is necessary to measure the gear body 3, the laser measuring instrument body 449 is started, and the measurement work is carried out in cooperation with the control panel 2. When it is necessary to adjust the measurement angle, the motor 442 is started, and the rotating rod 443 fixedly installed at the output end thereof rotates accordingly. The rotating rod 443 drives the connecting block 447 hinged inside it to rotate, and the connecting block 447 drives the laser measuring instrument body 449 to rotate accordingly, so as to rotate and adjust the measurement angle. When it is necessary to measure the side part, the clamping rod 445 is pulled out, and the laser measuring instrument body 449 and the connecting block 447 are rotated so that the connecting block 447 rotates with the hinge point with the rotating rod 443 as the rotation center. After the angle adjustment is completed, the clamping rod 445 is clamped into the rotating rod 443 and the card hole 448. Under the magnetic attraction restriction of the first magnetic ring 444 and the second magnetic ring 446, the clamping rod 445 can be prevented from falling off the rotating rod 443. This structure can flexibly adjust the measurement angle to obtain more measurement data.

[0028] Among them, the outer wall of the sealing frame 417 slides in a sealed manner inside the fixed frame 418. The fixed frame 418 is fixedly installed on the top surface of the processing table 1. When the first connecting plate 414 pulls the moving frame 415, the moving frame 415 drives the sealing frame 417 to slide outward from the fixed frame 418, and the inside of the fixed frame 418 is subjected to air suction treatment.

[0029] Among them, there are two groups of the moving frame 415 and the fixed frame 418, which are symmetrically distributed along the center line of the top surface of the processing table 1. Under the protection of the moving frame 415 and the fixed frame 418, the laser measuring instrument body 449 can be prevented from being affected by external dust during measurement.

[0030] Among them, a frame groove is provided inside the fixed frame 418. The fixed frame 418 is communicated with the connecting pipe 420 through the pipe groove 419, and the connecting pipe 420 is communicated with the air head 422 through the air plate 421. The adsorption plate 426 is made of an adsorption-type material. Under the combined use of the air head 422 and the adsorption plate 426, the dust in the measurement environment can be cleaned to improve the measurement accuracy.

[0031] Among them, the outer wall of the clamping rod 435 is made of a flexible material. There are six clamping rods 435, which are distributed circumferentially around the center of the sleeve block 432. Under the restriction of the clamping rods 435 made of the flexible material on the outer wall, the inner side of the gear body 3 can be prevented from being scratched. The flexible clamping rods 435 will not affect the clamping accuracy and stability of the gear body 3.
