Description

Technical field

[0001] The invention belongs to the technical field of measuring devices, and in particular relates to a tool measuring device. [Background Technology]

[0002] When measuring a tool, existing measuring devices secure the tool to the device. A one-dimensional laser sensor then scans the tool using a laser beam perpendicular to its axis. The scanned data is analyzed to produce a result, measuring the tool's diameter and runout. However, when the tool's diameter varies along the axial direction, it's impossible to accurately determine the axial position of the tool corresponding to the test result. This results in poor repeatability and reproducibility of the tool's diameter, and the smaller the tool's diameter, the lower the measurement accuracy. Therefore, it is necessary to provide a tool measuring device that accurately reflects the tool's axial position corresponding to the measurement result. [Summary of the invention]

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1 and Figure 2 A tool measuring device includes: a base 100, a measuring component 3 installed on the base 100, a first driving mechanism 1 installed on the base 100, and a fixture component 2 slidably assembled on the base 100 and connected to the first driving mechanism 1, the measuring component 3 includes a first support member 31 installed on the base 100 and a measuring head 33 installed on the side of the first support member 31 away from the base 100, the sliding assembly direction of the fixture component 2 intersects with the measuring direction of the measuring head 33, the measuring head 33 is provided with a measuring area, the fixture component 2 is used to clamp the measured tool 200 so that the extension direction of the measured tool 200 is perpendicular to the measuring direction, and the first driving mechanism 1 is used to drive the fixture component 2 to slide in a direction close to or away from the measuring area.

[0026] The first drive mechanism 1 drives the fixture assembly 2 to slide toward or away from the measurement area, allowing the tool 200 to be measured, which is clamped by the fixture assembly 2, to move within the measurement area, thereby achieving precise control of the axial position of the tool 200 to be measured. Furthermore, the extension direction of the tool 200 to be measured, which is clamped by the fixture assembly 2, is perpendicular to the measurement direction of the measuring head 33, enabling the measuring head 33 to ensure measurement accuracy when measuring the tool 200 to be measured. The fixture assembly 2 clamps the tool 200 to be measured, and the first drive mechanism 1 drives the fixture assembly 2 to move, thereby driving the tool 200 to be measured to move within the measurement area of ​​the measuring head 33, enabling the measuring head 33 to measure any axial position of the tool 200 to be measured, ensuring a one-to-one correspondence between the measurement results obtained by the measuring head 33 and the axial position of the tool 200 to be measured. This enables the tool measuring device to accurately feedback the measurement results corresponding to the tool axial position, while also improving the repeatability and reproducibility of tool diameter testing.

[0027] Reference Figure 1 and Figure 2 The first driving mechanism 1 includes a shell 11 mounted on the base 100, a first guide rail 12 mounted on the side of the shell 11 away from the base 100, and a first driving source 13 mounted at one end of the shell 11. The measuring direction of the measuring head 33 intersects with the length direction of the first guide rail 12. The clamp assembly 2 is slidably assembled on the first guide rail 12, and the first driving source 13 is connected to the clamp assembly 2. In some implementations of this embodiment, the base 100 can be a marble platform, the first driving source 13 can be a motor, and a screw rod 14 is connected to the output end of the first driving source 13 through a coupling. The screw rod 14 is rotatably assembled on the side of the shell 11 away from the base 100. The first guide rail 12 is slidably assembled with a slider connected to the screw rod 14. A mounting plate 15 is fixedly mounted on the side of the slider away from the shell 11. The mounting plate 15 is connected to the clamp assembly 2 on the side away from the slider. The first driving source 13 drives the slider to slide on the first guide rail 12 through the screw rod 14, so that the clamp assembly 2 follows the slider to slide on the first guide rail 12. Preferably, in one embodiment, the first driving mechanism 1 can be a PA300 linear module manufactured by Zhuoli Hanguan, which has a stroke of 300 mm and can perform motion control of the linear module through a motion control card and a driver; wherein, the first driving source 13 is a stepping motor, and the screw rod 14 is a ball screw rod 14, which can realize the precise movement of the fixture assembly 2; the first guide rail 12 is a linear guide rail, and two first guide rails 12 are arranged in parallel with the screw rod 14 on the side of the shell 11 away from the base 100, and the two ends of the slider are respectively slidably assembled on the two first guide rails 12, which is conducive to the smooth sliding of the fixture assembly 2 on the first guide rail 12; the length direction of the first guide rail 12 is perpendicular to the measuring direction of the measuring head 33, so that the measured tool 200 clamped by the fixture assembly 2 can enter the measuring area in a direction perpendicular to the measuring direction of the measuring head 33, thereby ensuring the measurement accuracy of the measuring head 33. In other implementations of this embodiment, the first drive mechanism 1 can also be replaced with a linear module of other brands or models according to actual needs, such as a linear module driven by a servo motor; the first drive mechanism 1 can also be driven by manual control, and the first drive source 13 is a rotating handle, and the rotating handle is connected to the screw rod 14. When the rotating handle is rotated, the screw rod 14 rotates with the rotating handle, thereby realizing the sliding of the slider on the first guide rail 12. It can be understood that a scale can be marked on the rotating handle, and the scale can be used to achieve precise control of the movement of the clamp assembly 2, such as: when the rotating handle is rotated 5°, the clamp assembly 2 moves 0.1mm.

[0028] Reference Figure 1 、 Figure 3 and Figure 4The fixture assembly 2 includes a second support member 21 slidably assembled on the first guide rail 12, a clamping mechanism 23 movably mounted on the side of the second support member 21 away from the base 100, and a clamping member 22 mounted on the side of the second support member 21 away from the base 100. A limiting groove 221 for accommodating the measured tool 200 is provided on the side of the clamping member 22 away from the base 100. The length extension direction of the limiting groove 221 intersects with the measuring area. The clamping mechanism 23 is used to press the measured tool 200 in the limiting groove 221. The clamping mechanism 23 is used to drive the measured tool 200 to rotate in the limiting groove 221. In some implementations of this embodiment, the second support member 21 includes a second base plate 211 mounted on the side of the mounting plate 15 away from the slider, and a first connecting plate 212 mounted on the side of the second base plate 211 away from the mounting plate 15 and perpendicular to the plate surface of the second base plate 211. The clamping mechanism 23 is mounted on the side of the first connecting plate 212 away from the second base plate 211. The clamping member 22 is mounted on the side of the first connecting plate 212 away from the second base plate 211 and is located below the clamping mechanism 23. When the clamping mechanism 23 rotates a predetermined angle toward the direction close to the first connecting plate 212, the clamping mechanism 23 can clamp the measured tool 200 within the limiting groove 221. The clamping member 22 can be a rectangular block, and a limiting groove 221 is defined on the side of the clamping member 22 away from the first connecting plate 212. Preferably, in one embodiment, the length extension direction of the limiting groove 221 is perpendicular to the measuring area. After the measured tool 200 is placed in the limiting groove 221, the length direction of the measured tool 200 is parallel to the length direction of the limiting groove 221, so that the measured tool 200 is perpendicular to the measuring direction of the measuring head 33, thereby improving the measurement accuracy.

[0029] Reference Figure 3 and Figure 4The limiting groove 221 includes two oppositely disposed side walls. Both side walls of the limiting groove 221 have positioning grooves 222 extending in a direction perpendicular to the length of the limiting groove 221. The bottom surface of the positioning groove 222 is parallel to the corresponding side walls. The fixture assembly 2 also includes a positioning rod 223 embedded in the positioning groove 222. The positioning rod 223 is cylindrical, and the diameter of the positioning rod 223 is greater than the depth of the positioning groove 222. In some embodiments of this embodiment, the limiting groove 221 can be a V-shaped groove, and the positioning rod 223 can be a cylindrical ceramic rod. When the tool 200 to be tested rolls in the limiting groove 221, the positioning rod 223 being a cylindrical ceramic rod can reduce the friction between the tool 200 to be tested and the positioning rod 223, thereby reducing the wear of the tool 200 to be tested. The two side walls of the limiting groove 221 can each have a plurality of positioning grooves 222 spaced apart. Preferably, in one embodiment of the present invention, two spaced apart positioning grooves 222 are respectively formed on the two side walls of the limiting groove 221, and the positioning grooves 222 on the two side walls are arranged relative to each other, so that the positioning rods 223 embedded in the positioning grooves 222 are symmetrically distributed within the limiting groove 221 with the length extension direction of the limiting groove 221 as the symmetry axis. This facilitates the stable placement of the measured tool 200 within the limiting groove 221, and ensures the rotation accuracy of the measured tool 200 when the measured tool 200 rolls, thereby improving measurement accuracy. One end of the positioning groove 222 extends to the bottom of the limiting groove 221, and the other end of the positioning groove 222 extends to the edge of the side wall of the limiting groove 221, making it easier to embed the positioning rod 223 into the positioning groove 222. The bottom of the limiting groove 221 protrudes toward the positioning groove 222 to form a raised portion 2211. The raised portion 2211 is located in the middle of one end of the positioning groove 222. The raised portion 2211 helps ensure that the positioning rod 223 is embedded in the positioning groove 222 parallel to the sidewalls of the limiting groove 221. The diameter of the positioning rod 223 is greater than the depth of the positioning groove 222, ensuring that the circumference of the positioning rod 223 protrudes from the sidewalls of the limiting groove 221. In other implementations of this embodiment, the number of positioning grooves 222 provided in the limiting groove 221 can be adjusted according to actual needs, such as six or eight.

[0030] Reference Figure 3 、 Figure 4 and Figure 5The pressing mechanism 23 includes a rotating member 231 rotatably connected to the side of the second support member 21 away from the base 100, a pressing wheel 232 rotatably assembled on one end of the rotating member 231, and a second driving mechanism 233 assembled on the rotating member 231 and connected to the pressing wheel 232. The rotating member 231 is used to drive the pressing wheel 232 to press against the limiting groove 221. The wheel surface of the pressing wheel 232 is perpendicular to the length direction of the limiting groove 221. The second driving mechanism 233 is used to drive the pressing wheel 232 to rotate. In some embodiments of this embodiment, the rotating member 231 can be a rectangular pressing block, and the pressing wheel 232 can be a circular disc. The first connecting plate 212 is fixedly connected to the pressure rod bracket 25 on the side away from the second bottom plate 211. The rotating member 231 is rotatably assembled on the end of the pressure rod bracket 25 away from the first connecting plate 212, and one end of the rotating member 231 is located above the clamping member 22. The pressing wheel 232 is provided at the end of the rotating member 231 located above the clamping member 22. The wheel surface of the pressure wheel 232 is perpendicular to the length direction of the limiting groove 221, which can ensure that when the pressure wheel 232 contacts the measured tool 200, the measured tool 200 is only subjected to the radial force applied by the pressure wheel 232, preventing the measured tool 200 from being subjected to axial force and thus moving axially. The second drive mechanism 233 drives the pressure wheel 232 to rotate, causing the measured tool 200 to roll within the limiting groove 221, achieving the rolling of the measured tool 200 within the measurement area of ​​the measuring head 33, and completing the runout test of the measured tool 200. Preferably, a rubber ring 2321 is installed on the pressure wheel 232 to increase the friction between the pressure wheel 232 and the measured tool 200. At the same time, due to the elasticity of the rubber ring 2321, the pressure wheel 232 can prevent damage to the measured tool 200. One end of the rotating part 231 is arranged above the end of the clamping part 22 away from the limiting groove 221, and the material is dug out at the end of the clamping part 22 away from the limiting groove 221 to form an avoidance space. When one end of the rotating part 231 is located in the avoidance space, the pressing wheel 232 abuts against the tool 200 to be measured, which is beneficial to ensure that when measuring tools 200 of different diameters, the pressing wheel 232 can press the tool 200 to be measured.

[0031] Reference Figure 3 、 Figure 4 and Figure 5The second driving mechanism 233 includes a first synchronous wheel 2331 rotatably connected to the rotating member 231, a second synchronous wheel 2332 rotatably connected to the rotating member 231, a transmission member 2334 connected to the first synchronous wheel 2331 and the second synchronous wheel 2332, and a driving member 2333 connected to the second synchronous wheel 2332. The clamping wheel 232 is coaxially fixed to the first synchronous wheel 2331, and the driving member 2333 is used to drive the second synchronous wheel 2332 to rotate. In some implementations of this embodiment, the transmission member 2334 can be a conveyor belt, the driving member 2333 can be a driving handwheel, and the driving member 2333 is rotated. At this time, the second synchronous wheel 2332 rotates following the driving member 2333, and the second synchronous wheel 2332 drives the first synchronous wheel 2331 to rotate through the transmission member 2334. The pressure wheel 232 rotates coaxially with the first synchronous wheel 2331, so that the pressure wheel 232 rotates with the length direction of the limiting groove 221 as the rotation direction, thereby ensuring that no axial force is generated between the pressure wheel 232 and the measured tool 200, causing the measured tool 200 to move axially. Preferably, in one embodiment, the transmission member 2334 is provided with a gear, and the second synchronous wheel 2332 and the first synchronous wheel 2331 are also provided with gears. The second synchronous wheel 2332 and the first synchronous wheel 2331 are of the same composition. The transmission member 2334 and the second synchronous wheel 2332, as well as the transmission member 2334 and the first synchronous wheel 2331, are meshed and assembled, ensuring smoother and more stable force transmission between the second synchronous wheel 2332 and the first synchronous wheel 2331. The first synchronous wheel 2331 is connected to the pressure wheel 232 via a core shaft 2335. The core shaft 2335 passes through the transmission member 2334 and is rotatably assembled on the transmission member 2334. The length of the core shaft 2335 is parallel to the rotation axis of the rotating member 231. This allows the pressure wheel 232 to rotate with the rotating member 231 to compress the tool 200 being measured, and also to rotate with the first synchronous wheel 2331 to drive the tool 200 being measured. This simple structure is advantageous in cost savings. In other implementations of this embodiment, the second synchronous wheel 2332 and the first synchronous wheel 2331 can be directly meshed and assembled together; the driving member 2333 can be a motor, and the second synchronous wheel 2332 can be a gear fixed to the output end of the driving member 2333. The driving member 2333 directly drives the first synchronous wheel 2331 to rotate. It can be understood that when the driving member 2333 is a motor, the clamping wheel 232 can also be directly driven to rotate by the driving member 2333. At this time, the driving member 2333 is installed on the rotating member 231 and rotates with the rotating member 231.

[0032] Reference Figure 3 and Figure 5The clamp assembly 2 further includes a connecting shaft 234 that passes through the second support member 21. The middle portion of the rotating member 231 is rotatably connected to the connecting shaft 234. The second synchronous wheel 2332 is rotatably connected to the connecting shaft 234. In some implementations of this embodiment, the pressure rod bracket 25 extends from one end away from the first connecting plate 212 to form two brackets spaced apart. The rotating member 231 is located between the two brackets of the pressure rod bracket 25. The connecting shaft 234 passes through the rotating member 231 and the two brackets of the pressure rod bracket 25 and is assembled to the pressure rod bracket 25. The second synchronous wheel 2332 is rotatably connected to one end of the connecting shaft 234. Preferably, in one embodiment, the driving member 2333 is sleeved on the circumference of the connecting shaft 234 and fixed to the connecting shaft 234, the second synchronous wheel 2332 includes a connecting portion fixed to the connecting shaft 234 and sleeved on the circumference of the connecting shaft 234 and a rack portion connected to the connecting portion and sleeved on the circumference of the connecting shaft 234, the connecting portion is provided with two pin holes set at intervals, and the connecting shaft 234 is fixed with a pin 2341 matching the pin hole. When the pin 2341 of the connecting shaft 234 is embedded in the pin hole, the connecting portion is fixed to the connecting shaft 234. At this time The second synchronous wheel 2332 is fixed to the connecting shaft 234. By fixing the driving member 2333 and the second synchronous wheel 2332 to the connecting shaft 234, the driving member 2333 and the second synchronous wheel 2332 can be ensured to rotate coaxially. It can be understood that the core shaft 2335 is also fixed with a pin 2341. The first synchronous wheel 2331 is provided with a pin hole that matches the pin 2341. After the pin 2341 on the core shaft 2335 is embedded in the pin hole of the first synchronous wheel 2331, the first synchronous wheel 2331 is fixed to the core shaft 2335. A blocking ring 2342 is fixed to the end of the connecting shaft 234 away from the driving member 2333. The side of the blocking ring 2342 close to the pressure rod bracket 25 abuts against the pressure rod bracket 25 to ensure that the connecting shaft 234 does not disengage from the pressure rod bracket 25 when rotating. In other implementations of this embodiment, the connecting shaft 234 can also be fixed to the pressure rod bracket 25, the rotating member 231 can be movably assembled on the connecting shaft 234, the second synchronous wheel 2332 can be rotatably assembled on the connecting shaft 234, the driving member 2333 is connected to the second synchronous wheel 2332, and the driving member 2333 drives the second synchronous wheel 2332 to rotate.

[0033] Reference Figure 1 、 Figure 3 and Figure 4The limiting groove 221 has openings at both ends in the longitudinal direction. A push rod 24 is mounted on the side of the second support member 21 away from the measuring assembly 3. The length direction of the push rod 24 is parallel to the length direction of the limiting groove 221, and the length direction of the push rod 24 extends through the opening. In some implementations of this embodiment, the opening of the limiting groove 221 can be V-shaped. A second connecting plate 213 is mounted on the side of the first connecting plate 212 away from the measuring assembly 3. The second connecting plate 213 defines a channel for mounting the push rod 24. The push rod 24 can slide within the channel of the second connecting plate 213, so that the distance between the push rod 24 and the limiting groove can be adjusted. After the push rod 24 abuts against the measured tool 200, the measured tool 200 cannot move axially. Preferably, in one embodiment, the second connecting plate 213 is perpendicular to the plate surface of the first connecting plate 212 away from the second bottom plate 211, and the second connecting plate 213 is located on the plate surface of the first connecting plate 212 away from the measuring component 3. The second connecting plate 213 is provided with an adjustment through hole 2131, and the adjustment through hole 2131 can be a waist-shaped hole. The length extension direction of the adjustment through hole 2131 is perpendicular to the length direction of the positioning groove 222. A screw is installed between the second connecting plate 213 and the first connecting plate 212, and the screw is located in the adjustment through hole 2131. It can be understood that after the screw is loosened, the second connecting plate 213 can slide relative to the first connecting plate 212, and the push rod 24 follows the movement of the second connecting plate 213 to adjust the height of the push rod 24, which is conducive to enabling the push rod 24 to resist the measured tools 200 of different diameters, thereby enhancing the practicality of the push rod 24. The second connecting plate 213 defines a through hole that communicates with the channel of the second connecting plate 213 . Screws can be installed in the through hole of the second connecting plate 213 to press and fix the push rod 24 to the second connecting plate 213 .

The second guide rail 37 extends perpendicular to the surface of the base 100. The measuring head 33 is mounted on the side of the beam 34 away from the base 100. The third driving mechanism 32 is used to drive the beam 34 to slide on the second guide rail 37.
