[0024] 3. After the arc-shaped clamping plate clamps the threaded sleeve, the rotating ring drives the plug rod to move to the position of the insertion hole, so that the plug rod is inserted into the corresponding insertion hole, fixing the position of the rotating ring, thereby avoiding the situation that its rotation under the action of an external force affects the clamping effect of the arc-shaped clamping plate.

Detailed implementation manners

[0033] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] As Figures 1 - 7 shown, a digital display tool wear measurement device includes a support table 1. A groove 101 is formed on the upper surface of the support table 1. A support column 2 is movably arranged in the groove 101. An installation sleeve 3 is fixedly installed at the upper end of the support column 2. A detection component 4 for detecting the wear degree of the tool tip is arranged in the installation sleeve 3;

[0035] A threaded section 201 is arranged on the column body of the support column 2. A control component 5 for controlling the movement of the support column 2 is arranged on the upper surface of the support table 1.

[0036] Through the above technical solution, the staff fixes the support table 1 on the working surface, and then controls the lifting system to drive the tool tip to descend, so that the detection component 4 can detect the wear condition of the tool tip. When the support table 1 is fixed on working surfaces at different horizontal heights, the staff uses the control component 5 to control the detection component 4 to rise, so that the staff can quickly adjust the height of the position where the detection component 4 is located, without the need for the staff to make additional adjustments or take other measures, greatly reducing the complexity and difficulty of the operation and improving the work efficiency.

[0037] In this embodiment, the detection component 4 includes a sliding plate 401. The sliding plate 401 is slidably arranged inside the installation sleeve 3. A top plate 403 is fixedly installed on the upper surface of the sliding plate 401 through a support rod 402. A pressing plate 404 is fixedly installed on the upper surface of the top plate 403;

[0038] A positioning frame 405 is fixedly installed on the lower surface of the top plate 403. An infrared lamp 406 is arranged on one side of the inner wall of the positioning frame 405. A photodiode receiver 407 is arranged at one end of the positioning frame 405 away from the infrared lamp 406. Connecting frames 408 are fixedly installed on both sides of the positioning frame 405. A grid window 409 is arranged between the two connecting frames 408. A support plate 410 is fixedly installed inside the installation sleeve 3. A scale glass 411 is fixedly installed on the lower surface of the support plate 410. A first spring 412 is arranged at the bottom inside the installation sleeve 3;

[0039] One end of the photodiode receiver 407 is provided with a wire 413. An avoidance groove 414 is formed on the inner wall surface of the installation sleeve 3. One end of the wire 413 passes through the avoidance groove 414 and is provided with a digital display 415. The digital display 415 is fixedly installed on one side of the support table 1 through a fixing frame 416.

[0040] On both sides of the inner wall of the installation sleeve 3, limiting grooves 6 are provided, and limiting blocks 601 are slidably arranged in the two limiting grooves 6. The sliding plate 401 is fixedly installed between the two limiting blocks 601.

[0041] When the lifting system drives the tool head to descend and press the pressing plate 404, the pressing plate 404, the sliding plate 401, the grid window 409, the photodiode receiver 407 and the infrared lamp 406 move along the installation sleeve 3, and the first spring 412 is compressed under force. When the grid window 409, the photodiode receiver 407 and the infrared lamp 406 move relative to the grating glass 411, the infrared light generated by the infrared lamp 406 forms Moiré fringes through the superposition of the grating glass 411 and the grid window 409. These fringes produce light and dark changes on the photodiode receiver 407, thereby generating an electrical signal. Subsequently, the electrical signal is transmitted to the digital display 415 through the wire 413, enabling the digital display 415 to display the displacement information of the grating scale. After the lifting system drives the tool head to reset, the first spring 412 resets and drives the top plate 403 to reset.

[0042] It should be noted that the control assembly 5 includes a connecting ring 501. The connecting ring 501 is fixedly installed in the middle of the upper surface of the support table 1. A threaded sleeve 503 is rotatably installed in the connecting ring 501 through a first bearing 502, and the threaded section 201 is threadedly arranged inside the threaded sleeve 503.

[0043] Two limiting rods 7 are fixedly installed at the lower end of the support column 2. Two limiting holes 8 are provided on the bottom surface of the groove 101, and the two limiting rods 7 are respectively slidably arranged inside the corresponding limiting holes 8.

[0044] The staff rotates the threaded sleeve 503, and the rotating threaded sleeve 503 drives the threaded section 201, the support column 2, the top plate 403 and the limiting rods 7 to move along the direction of the limiting holes 8 by means of screw-in, so that the staff can quickly control the lifting of the top plate 403, and further can quickly adjust the height of the position where the top plate 403 is located.

[0045] It can be understood that in this application, a plurality of sliding grooves 9 are provided on the upper surface of the support table 1. A slider 901 is slidably arranged in each sliding groove 9, and a first right-angle bracket 902 is fixedly installed on the upper surface of each slider 901. An arc-shaped clamping plate 903 is fixedly installed on one side of each first right-angle bracket 902 close to the threaded sleeve 503.

[0046] An installation ring 10 is fixedly installed on the upper surface of each support table 1. A rotating ring 1002 is rotatably installed in the installation ring 10 through a second bearing 1001, and a plurality of first hemispherical blocks 1003 are fixedly installed on the inner wall of the rotating ring 1002;

[0047] A second hemispherical block 16 is fixedly installed on one side of each first right-angle bracket 902 away from the threaded sleeve 503.

[0048] A slide bar 11 is fixedly installed between the two sides of the inner wall of each chute 9. Each slider 901 is slidably arranged on one side of the corresponding slide bar 11, and a second spring 1101 is sleeved on the other side of each slide bar 11.

[0049] After adjusting the top plate 403 to a suitable height, the staff rotates the rotating ring 1002, so that the first hemispherical block 1003 can rotate with the rotating ring 1002 based on the second bearing 1001, thereby pushing the second hemispherical block 16, causing the first right-angle bracket 902 and the slider 901 to move along the chute 9, and further clamping the threaded sleeve 503 with the arc-shaped clamping plate 903, avoiding that after the pressure plate 404 is adjusted to a suitable height by the staff, the threaded sleeve 503 rotates under the action of an external force, resulting in the movement of the pressure plate 404, and the pressure plate 404 cannot maintain its original position and height, affecting the accuracy during tool setting.

[0050] It can be understood that in this application, two second right-angle brackets 12 are fixedly installed at the upper end of the rotating ring 1002. A plug rod 1201 is movably penetrated through one side of each second right-angle bracket 12 away from each other. A push block 1202 is fixedly installed at the common end of the adjacent plug rods 1201 away from the support table 1. A limiting plate 1203 is sleeved on the common side of the adjacent plug rods 1201 close to the support table 1. A third spring 1204 is sleeved on one side of each plug rod 1201 close to the corresponding limiting plate 1203;

[0051] A number of jacks 13 are formed on the outer wall surface of the support table 1.

[0052] After the arc-shaped clamping plate 903 clamps the threaded sleeve 503, the rotating ring 1002 drives the plug rod 1201 to move to the position of the jack 13, so that the plug rod 1201 is inserted into the corresponding jack 13, fixing the position of the rotating ring 1002 and avoiding the situation that its rotation under the action of an external force affects the clamping effect of the arc-shaped clamping plate 903.

[0053] It can be understood that in this application, an air pipe 15 is fixedly installed on the body of each pressure plate 404 through a pipe rack 14.

[0054] By providing the air pipe 15, after the tool tip is separated from the pressure plate 404, the staff conveys gas into the air pipe 15, and the gas can blow the upper surface of the pressure plate 404, so that the debris remaining on the upper surface of the pressure plate 404 and falling from the tool tip is blown off.

[0055] The working principle of this digital display tool wear measurement device:

[0056] During use, first, the staff fix the support table 1 on the working surface, and then control the lifting system to drive the cutter head to descend. When the lifting system drives the cutter head to descend and press the pressure plate 404, the pressure plate 404, the slide plate 401, the grid window 409, the photodiode receiver 407, and the infrared lamp 406 move along the mounting sleeve 3, and the first spring 412 is compressed. When the grid window 409, the photodiode receiver 407, and the infrared lamp 406 move relative to the grating glass 411, the infrared light generated by the infrared lamp 406 forms Moiré fringes through the superposition of the grating glass 411 and the grid window 409. These fringes produce brightness changes on the photodiode receiver 407, thereby generating an electrical signal. Subsequently, the electrical signal is transmitted to the digital display 415 through the wire 413, enabling the digital display 415 to display the displacement information of the grating scale. After the lifting system drives the cutter head to reset, the first spring 412 resets and drives the top plate 403 to reset. When the support table 1 is fixed on working surfaces at different horizontal heights, the staff rotate the threaded sleeve 503, and the rotating threaded sleeve 503 drives the threaded section 201, the support column 2, the top plate 403, and the limit rod 7 to move along the direction of the limit hole 8 by means of screw-in, so that the staff can quickly control the lifting of the top plate 403, and thus can quickly adjust the height of the position where the top plate 403 is located, without the need for the staff to make additional adjustments or take other measures, greatly reducing the complexity and difficulty of the operation and improving the work efficiency.

[0057] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
