Description

Technical Field

[0001] The present invention relates to the field of laser measurement, and specifically to a laser measuring instrument for the inner diameter of metal workpieces. Background Technique

[0002] Metal workpieces refer to parts or products with metal materials as the processing objects during the machining process. A laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. It measures the time from the emission to the reflection of the laser, and then calculates the distance between the laser and the target object based on the principle of the constant speed of light. Laser rangefinders have the advantages of fast measurement speed, high accuracy, and simple operation, and are widely used in terrain measurement, battlefield measurement, industrial measurement and control, mines, ports and other fields. A laser measuring instrument for the inner diameter of metal workpieces is an instrument used to measure the inner diameter of metal workpieces. It uses laser technology for measurement and has the characteristics of high precision and non-contact measurement.

[0003] As disclosed in a laser measuring instrument for the inner diameter of metal workpieces in Chinese Patent CN118794362B, while the mounting plate drives the main measuring column to descend, the mounting plate will drive the regulating plate and the pressing plate to descend together, and then the pressing plate squeezes the gas in the air storage airbag into the diversion frame, so that the gas enters the flow channel, and later the gas sprays out through the lower through hole, which is convenient to blow away the dust in the surrounding environment of the first laser rangefinding component. At the same time, since the lower through hole is inclined, the wind blown out by the lower through hole will also blow to the surface of the first laser rangefinding component, and then it is convenient to blow off the dust and impurities on the surface of the first laser rangefinding component, so that the amount of dust in the surrounding environment of the first laser rangefinding component is greatly reduced, and then it is avoided that a large amount of dust affects the optical measurement accuracy of the laser measuring instrument. Therefore, it is convenient for the first laser rangefinding component to measure the inner diameter of the metal workpiece well.

[0004] For this structure, although the dust around the laser measuring instrument can be cleaned, the measuring steps of this measuring instrument are cumbersome, resulting in inconvenient measurement. Therefore, we propose a laser measuring instrument for the inner diameter of metal workpieces that can be flexibly adjusted for measurement to make the measurement more convenient. Summary of the Invention

[0005] The purpose of the present invention is to provide a laser measuring instrument for the inner diameter of metal workpieces to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A laser measuring instrument for the inner diameter of a metal workpiece, including a bracket, a laser measuring instrument body is provided below the bracket, a bottom plate is fixedly installed at the bottom end of the bracket, and a processing component is arranged outside the laser measuring instrument body. The processing component includes an adjusting component arranged outside the laser measuring instrument body, a fixing component is arranged outside the adjusting component, and a dust blowing component is arranged outside the fixing component.

[0007] According to the above technical solution, the adjusting component includes a fixed disk fixedly installed on the bottom side of the bracket. A chute is opened on the outer wall of the fixed disk. A first spring is fixedly installed on the inner wall of the chute. A limiting plate is fixedly installed at the end of the first spring. A clamping block is fixedly installed on the side of the limiting plate away from the first spring. An installation plate is fixedly installed at the bottom of the fixed disk. A motor is fixedly installed at the bottom of the installation plate. A reciprocating lead screw is fixedly installed at the output end of the motor. A sleeve block is sleeved on the outer wall of the reciprocating lead screw. The reciprocating lead screw is rotatably connected to a chassis at the end away from the motor. A limiting sleeve is fixedly installed on the outer wall of the sleeve block. A limiting rod is slidably arranged inside the limiting sleeve. A limiting disk is fixedly installed at the end of the limiting rod. A first vertical plate is fixedly installed on the side of the sleeve block away from the limiting sleeve. A worm is rotatably connected inside the first vertical plate. A worm gear is engaged on the outer wall of the worm. The side wall of the worm gear is rotatably connected to a second vertical plate. A connecting frame is arranged outside the second vertical plate.

[0008] According to the above technical solution, the fixing component includes a fixed block fixedly installed on the outer wall of the chassis. A sleeve is fixedly installed inside the fixed block. A suction cup is fixedly installed at the bottom end of the sleeve. A retaining ring is fixedly installed on the inner wall of the sleeve. A second spring is fixedly installed on the top surface of the retaining ring. A sealing ring is fixedly installed at the end of the second spring away from the retaining ring. A sliding rod is fixedly installed on the side of the sealing ring away from the second spring. A limiting ring is fixedly installed on the outer wall of the sliding rod.

[0009] According to the above technical solution, the dust blowing component includes a support plate fixedly installed on the outer wall of the bottom plate. An air pump is fixedly installed on the top surface of the support plate. An air pipe is communicated with the top surface of the air pump. The end of the air pipe away from the air pump is communicated with a blowing plate.

[0010] According to the above technical solution, the outer wall of the limiting disk is slidably arranged in a ring groove opened on the top surface of the chassis. The outer wall of the limiting rod is arranged in an inclined plane. Under its restriction, when the clamping block contacts the inclined plane of the limiting rod, the limiting rod can squeeze the clamping block to adjust the orientation of the laser measuring instrument body.

[0011] According to the above technical solution, the number of the clamping blocks is six, which are distributed circumferentially around the center of the fixed disk. Under the restriction of the six clamping blocks, the sleeve block can be restricted by the limiting rod, so that the rotating reciprocating lead screw can drive the sleeve block to move up and down.

[0012] According to the above technical solution, the outer wall of the sealing ring seals and slides inside the sleeve, and the outer wall of the sliding rod is slidably arranged inside the sleeve. Under the limitation of the sealing slide, the sealing ring can pump the air inside the sleeve and the suction cup, so that the suction cup adsorbs to the inner bottom surface of the metal workpiece.

[0013] According to the above technical solution, the outer wall of the air pipe is fixedly installed inside the bracket, and the outer wall of the blowing plate is fixedly installed inside the bracket. Under the limitation of the air pipe connection, air can be conveyed to the blowing plate through an air pump.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The metal workpiece inner diameter laser measuring instrument of the present invention includes an adjustment component as one of its components. When measuring the inner diameter of a metal workpiece, place the chassis in the measuring device inside the metal workpiece, and install and fix the chassis through the fixing component. At this time, start the motor, and the reciprocating screw fixedly installed at its output end rotates accordingly. When adjusting the height of the laser measuring instrument body, reverse the reciprocating screw, and the sleeve block sleeved on the outer wall of the reciprocating screw rotates in reverse accordingly. The sleeve block drives the limiting sleeve fixedly installed on its outer wall to rotate in reverse, and the limiting sleeve drives the limiting rod slidably arranged inside it to rotate in reverse. The limiting disk fixedly installed at the end of the limiting rod slides inside the chassis. When the side of the limiting rod away from its inclined surface is clamped with the side of the clamping block away from its inclined surface, at this time, the limiting rod limits the sleeve block and the reciprocating screw. The reciprocating screw rotating in reverse drives the sleeve block sleeved on its outer wall to move up and down, so that the limiting sleeve and the limiting rod slide on the outer wall, and the sleeve block moving up and down drives the laser measuring instrument body outside it to move up and down to adjust the measuring height of the laser measuring instrument body. After the adjustment is completed, start the motor to drive the reciprocating screw to rotate forward at this time, and the sleeve block sleeved on the outer wall of the reciprocating screw rotates forward accordingly. The sleeve block drives the limiting rod to rotate through the limiting sleeve, so that the inclined surface of the limiting rod contacts and presses against the inclined surface of the clamping block. The clamping block is driven by the extrusion to drive the limiting plate to slide into the chute and compress the first spring arranged inside the chute. At this time, the limiting rod and the clamping block are no longer clamped, and the measuring orientation of the laser measuring instrument body with the adjusted height can be changed. When the clamping block is not extruded, under the elastic action of the first spring, the limiting plate is pushed towards the outside of the chute to push the clamping block back to its original position. This structure can adjust the height of the laser measuring instrument body and can also adjust the measuring orientation of the laser measuring instrument body, making it flexible to use.

[0015] 2. The inner diameter laser measuring instrument for metal workpieces of the present invention includes an adjustment component as one of its parts. When it is necessary to adjust the measuring angle of the laser measuring instrument body, the worm is rotated at this time. Since the outer wall of the second vertical plate is fixedly installed on the outer wall of the reciprocating screw rod, and the side wall of the worm gear is rotatably connected to the second vertical plate, under its restriction, the rotating worm drives the worm gear meshed with it to rotate. Since the connecting frame fixedly installed on the outer wall of the worm gear is fixedly installed on the outer wall of the laser measuring instrument body, under its restriction, the rotating worm gear drives the laser measuring instrument body to rotate around the center of the worm gear, adjusting the measuring orientation of the laser measuring instrument body. Due to the resistance existing in the meshing of the worm and the worm gear, there is no need to limit it. This structure can flexibly adjust the measuring angle of the laser measuring instrument body, making the laser measuring instrument body easier to use.

[0016] 3. The inner diameter laser measuring instrument for metal workpieces of the present invention includes a fixing component as one of its parts. When measuring the inner diameter of a metal workpiece, place the chassis inside the metal workpiece, press the sliding rod, so that the sliding rod drives the sealing ring to slide towards the suction cup direction, compress the second spring through the retaining ring, and make the suction cup contact the inner bottom surface of the metal workpiece. At this time, release the sliding rod, and under the elastic action of the second spring, push the sealing ring away from the retaining ring direction. Since the sealing ring slides sealingly inside the sleeve, under its restriction, the sealing ring pumps the air inside the sleeve and the suction cup, making the suction cup adsorb to the inner bottom surface of the metal workpiece to fix the chassis stably on the inner bottom surface of the metal workpiece. This structure can stably fix the chassis, enabling the laser measuring instrument body to be stably adjusted and measured.

[0017] 4. The inner diameter laser measuring instrument for metal workpieces of the present invention includes a dust blowing component as one of its parts. When measuring the inner diameter of a metal workpiece, in order to make the measurement data accurate, it is necessary to clean the dust inside the metal. At this time, start the air pump, which conveys air into the blowing plate through the air pipe, and the blowing plate sprays out the gas to blow and clean the dust at the measurement location, avoiding the influence of dust on the measurement data accuracy.

[0023] Embodiment 1: A preferred embodiment of a laser inner diameter measuring instrument for metal workpieces provided by the present invention is as Figures 1 to 9 shown: A laser inner diameter measuring instrument for metal workpieces includes a bracket 1; A laser measuring instrument body 2 is provided below the bracket 1; The bottom end of the bracket 1 is fixedly installed with a bottom plate 3; and a processing component 4 arranged outside the laser measuring instrument body 2. The processing component 4 includes an adjusting component 41 arranged outside the laser measuring instrument body 2. The adjusting component 41 includes a fixed disk 411 fixedly installed on the bottom side of the bracket 1. A chute 412 is formed on the outer wall of the fixed disk 411. A first spring 413 is fixedly installed on the inner wall of the chute 412. A limiting plate 414 is fixedly installed at the end of the first spring 413. A clamping block 415 is fixedly installed on the side of the limiting plate 414 away from the first spring 413. An installation plate 416 is fixedly installed at the bottom of the fixed disk 411. A motor 417 is fixedly installed at the bottom of the installation plate 416. A reciprocating lead screw 418 is fixedly installed at the output end of the motor 417. A sleeve block 419 is sleeved on the outer wall of the reciprocating lead screw 418. One end of the reciprocating lead screw 418 away from the motor 417 is rotatably connected to a chassis 420. A limiting sleeve 428 is fixedly installed on the outer wall of the sleeve block 419. A limiting rod 422 is slidably arranged inside the limiting sleeve 428. A limiting disk 421 is fixedly installed at the end of the limiting rod 422. A first vertical plate 423 is fixedly installed on the side of the sleeve block 419 away from the limiting sleeve 428. A worm 424 is rotatably connected inside the first vertical plate 423. A worm gear 425 is meshed on the outer wall of the worm 424. The side wall of the worm gear 425 is rotatably connected to a second vertical plate 426. A connecting frame 427 is arranged outside the second vertical plate 426.

[0024] In this embodiment, when the inner diameter of a metal workpiece needs to be measured, the chassis 420 in the measuring device is placed inside the metal workpiece and fixed by the fixing component 43. At this time, the motor 417 is started, and the reciprocating lead screw 418 fixedly installed at its output end rotates accordingly. When the height of the laser measuring instrument body 2 needs to be adjusted, the reciprocating lead screw 418 is reversed. The sleeve block 419 sleeved on the outer wall of the reciprocating lead screw 418 rotates in reverse accordingly. The limiting sleeve 428 fixedly installed on the outer wall of the sleeve block 419 rotates in reverse accordingly. The limiting rod 422 slidably arranged inside the limiting sleeve 428 rotates in reverse. The limiting plate 421 fixedly installed at the end of the limiting rod 422 slides inside the chassis 420. When the side of the limiting rod 422 away from its inclined surface is engaged with the side of the clamping block 415 away from its inclined surface, at this time, the limiting rod 422 limits the sleeve block 419 and the reciprocating lead screw 418. The reversed reciprocating lead screw 418 drives the sleeve block 419 sleeved on its outer wall to move up and down, causing the limiting sleeve 428 to slide on the outer walls of the limiting rod 422. The sleeve block 419 moving up and down drives the laser measuring instrument body 2 outside it to move up and down, adjusting the height of the laser measuring instrument body 2 for measurement. After the adjustment is completed, the motor 417 is started to drive the reciprocating lead screw 418 to rotate forward. The sleeve block 419 sleeved on the outer wall of the reciprocating lead screw 418 rotates forward accordingly. The sleeve block 419 drives the limiting rod 422 to rotate through the limiting sleeve 428, causing the inclined surface of the limiting rod 422 to contact and press the inclined surface of the clamping block 415. The clamping block 415 is driven by the extrusion to drive the limiting plate 414 to slide into the chute 412 and compress the first spring 413 arranged inside the chute 412. At this time, the limiting rod 422 and the clamping block 415 are no longer engaged, and the measuring orientation of the laser measuring instrument body 2 with the adjusted height can be changed. When the clamping block 415 is not extruded, under the elastic action of the first spring 413, the limiting plate 414 is pushed outward in the direction of the outside of the chute 412 to push the clamping block 415 back to its original position. This structure can adjust the height of the laser measuring instrument body 2 and can also adjust the measuring orientation of the laser measuring instrument body 2, enabling it to be used flexibly. When the measuring angle of the laser measuring instrument body 2 needs to be adjusted, at this time, the worm 424 is rotated. Since the outer wall of the second vertical plate 426 is fixedly installed with the outer wall of the reciprocating lead screw 418, and the side wall of the worm gear 425 is rotatably connected to the second vertical plate 426, under its restriction, the rotating worm 424 drives the worm gear 425 meshed with it to rotate. Since the connecting frame 427 fixedly installed on the outer wall of the worm gear 425 is fixedly installed with the outer wall of the laser measuring instrument body 2, under its restriction, the rotating worm gear 425 drives the laser measuring instrument body 2 to rotate around the center of the worm gear 425, adjusting the measuring orientation of the laser measuring instrument body 2. Since there is resistance when the worm 424 meshes with the worm gear 425, there is no need to limit it. This structure can flexibly adjust the measuring angle of the laser measuring instrument body 2, making the laser measuring instrument body 2 easier to use.

[0025] Embodiment 2: A preferred embodiment of the inner diameter laser measuring instrument for metal workpieces provided by the present invention is as follows Figures 1 to 9 As shown: The fixing component 43 includes a fixing block 431 fixedly installed on the outer wall of the chassis 420. A sleeve 432 is fixedly installed inside the fixing block 431. A suction cup 433 is fixedly installed at the bottom end of the sleeve 432. A retaining ring 434 is fixedly installed on the inner wall of the sleeve 432. A second spring 435 is fixedly installed on the top surface of the retaining ring 434. One end of the second spring 435 away from the retaining ring 434 is fixedly installed with a sealing ring 436. A sliding rod 437 is fixedly installed on the side of the sealing ring 436 away from the second spring 435. A limiting ring 438 is fixedly installed on the outer wall of the sliding rod 437.

[0026] In this embodiment, when measuring the inner diameter of a metal workpiece, place the chassis 420 inside the metal workpiece. Press the sliding rod 437 to drive the sealing ring 436 to slide towards the suction cup 433. Compress the second spring 435 through the retaining ring 434 to make the suction cup 433 contact the inner bottom surface of the metal workpiece. At this time, release the sliding rod 437. Under the elastic action of the second spring 435, push the sealing ring 436 away from the retaining ring 434. Since the sealing ring 436 slides in a sealed manner inside the sleeve 432, under its restriction, the sealing ring 436 pumps the air inside the sleeve 432 and the suction cup 433, so that the suction cup 433 adsorbs to the inner bottom surface of the metal workpiece to fix the chassis 420 on the inner bottom surface of the metal workpiece. This structure can stably fix the chassis 420, enabling the laser measuring instrument body 2 to be stably adjusted and measured.

[0027] Embodiment 3: A preferred embodiment of the inner diameter laser measuring instrument for metal workpieces provided by the present invention is as follows Figures 1 to 9 As shown: The dust blowing component 44 includes a support plate 441 fixedly installed on the outer wall of the bottom plate 3.

One end of the air pipe 443 away from the air pump 442 is communicated and arranged with a blowing plate 444.

[0028] In this embodiment, when measuring the inner diameter of a metal workpiece, in order to make the measurement data accurate, it is necessary to clean the dust inside the metal. At this time, start the air pump 442, which conveys air into the blowing plate 444 through the air pipe 443, and the blowing plate 444 sprays out the gas to blow and clean the dust at the measurement location, avoiding the influence of dust on the accuracy of the measurement data.

[0029] Among them, the outer wall of the limiting disk 421 is slidably arranged in the annular groove opened on the top surface of the chassis 420. The outer wall of the limiting rod 422 is arranged in an inclined plane. Under its restriction, when the clamping block 415 contacts the inclined plane of the limiting rod 422, the limiting rod 422 can squeeze the clamping block 415 to adjust the orientation of the laser measuring instrument body 2.

[0030] Among them, there are six clamping blocks 415, which are distributed circumferentially around the center of the fixed disk 411. Under the restriction of the six clamping blocks 415, the sleeve block 419 can be restricted by the limiting rod 422, so that the reciprocating lead screw 418 in rotation can drive the sleeve block 419 to move up and down.

[0031] Among them, the outer wall of the sealing ring 436 slides in a sealed manner inside the sleeve 432, and the outer wall of the sliding rod 437 is slidably arranged inside the sleeve 432. Under the restriction of the sealed sliding, the sealing ring 436 can pump the air inside the sleeve 432 and the suction cup 433, so that the suction cup 433 adsorbs to the inner bottom surface of the metal workpiece.

[0032] Among them, the outer wall of the air pipe 443 is fixedly installed inside the bracket 1, and the outer wall of the blowing plate 444 is fixedly installed on the inner side of the bracket 1. Under the restriction of the connection of the air pipe 443, the air pump 442 can supply air to the blowing plate 444.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
