Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, specifically, it relates to the structure of an optical calibration plate alignment auxiliary device. Background Technology

[0002] An optical calibration plate is an optical calibration standard that can be used to calibrate the probes of measuring machines.

[0003] Before calibration, ensure that the X and Y sides of the center frame of the optical calibration plate are the same as the X and Y directions of the measuring machine, and that the light source point of the probe is located at the center of the center frame.

[0004] Therefore, before calibration, the positions of the optical calibration plate and the probe need to be adjusted so that both meet the calibration standard requirements.

[0005] The existing position adjustment method is as follows: First, the optical calibration plate is placed on the table of the measuring machine. Under the optical display, the center frame of the optical calibration plate will be displayed in the display window of the measuring machine. Then, the coordinate measuring machine is controlled to move the probe to be tested, so that the probe moves to one end of the horizontal side of the center frame. Then, the probe is controlled to move along the X direction to see if it can move to the other end of the horizontal side. If not, the optical image plate is rotated accordingly so that the light source point of the probe is aligned with the other end of the horizontal side, so as to achieve the purpose of adjusting the center frame to be the same as the X and Y directions of the measuring machine. However, because the size of the center frame is very small and the adjustment accuracy requirement is high, manual operation may cause over-adjustment with a little force. Manual adjustment is difficult and requires repeated adjustment, which takes a lot of time to align.

[0006] After aligning the center frame with the X and Y directions of the measuring machine, continue to adjust the light source point of the measurement to place it in the center position of the center frame. At this time, it is necessary to move the center light source of the probe to the center of the optical calibration plate by using the coordinate measuring machine. Since the center frame of the optical calibration plate is very small, it is difficult to place the center within the frame by moving the coordinate measuring machine, which requires multiple jog operations, making the operation difficult.

[0007] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0070] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0071] In some embodiments of this application, an optical calibration plate alignment auxiliary device is proposed. The optical calibration plate 200 is an optical calibration standard, which can be used to perform optical calibration on the probe to be calibrated in the measuring equipment, such as calibrating the probe to be calibrated in the coordinate measuring machine.

[0072] Multiple frames are provided on the optical verification plate 200, including the smallest frame located at the center, namely the central frame 210, and the center frame 210 has a center point at its center.

[0073] Before calibrating the probe to be calibrated on the corresponding measuring equipment, it is necessary to ensure that the X and Y directions of the central frame 210 of the optical calibration plate 200 are in the same direction as the X and Y directions of the measuring equipment such as a coordinate measuring machine, and that the light source point of the probe to be calibrated is aligned with the center point of the central frame 210, that is, the light source point is just projected onto the center point of the central frame 210, before the next step of calibration can be carried out.

[0074] Before calibration, the optical calibration plate 200 and the probe to be calibrated need to be aligned. In order to enable the optical calibration plate 200 and the probe to be calibrated to be quickly aligned, this embodiment proposes an optical calibration plate 200 alignment auxiliary device, which can help the optical calibration plate 200 to be quickly aligned with the machine's coordinate axis and the probe to be calibrated.

[0075] The optical calibration plate 200 alignment auxiliary device includes:

[0076] The substrate 100 is used to support the optical verification plate 200 and is rotatably connected to the optical verification plate 200.

[0077] When adjusting the position of the optical calibration plate 200, it can be achieved by rotating it relative to the substrate 100.

[0078] A rotation adjustment assembly 300 is connected between the substrate 100 and the optical verification plate 200, and is used to drive the optical verification plate 200 to rotate relative to the substrate 100 and to lock the optical verification plate 200 onto the substrate 100 when the optical verification plate 200 is rotated into position.

[0079] By using the rotation adjustment component 300, the optical calibration plate 200 can be rotated when needed, thereby quickly adjusting the optical calibration plate 200 to the correct position. After adjustment, the adjustment component 300 can be rotated to lock and fix the optical calibration plate 200 in place, preventing it from wobbling and avoiding the need for readjustment due to position changes caused by the movement of the optical calibration plate 200.

[0080] Specifically, during adjustment, the optical calibration plate 200 is placed on the measuring machine, such as... Figure 6 As shown, the center frame 210 on the optical calibration plate 200 will be displayed on the display window of the measuring machine. At this time, the probe to be calibrated can be moved to the A end position of the center frame 210 by adjusting the three-coordinate operation box on the measuring machine. Then, the probe to be calibrated can be moved along the X direction to the B end position of the center frame 210, which is opposite to the A end position. Check whether the light source point of the probe to be calibrated is at point B. If the light source point of the probe to be calibrated is not at point B, the optical calibration plate 200 can be rotated along the substrate 100 by rotating the adjustment component 300 so that the light source point of the probe to be calibrated coincides with the B point of the center frame 210.

[0081] Since the optical calibration plate 200 is rotatably connected to the substrate 100, when the rotation adjustment component 300 drives the optical calibration plate 200 to rotate, the optical calibration plate 200 can rotate along the set path by the corresponding angle. This allows the optical calibration plate 200 to be quickly rotated and adjusted into position, avoiding the problems of repeated adjustments caused by manual adjustment leading to deviation of the rotation path or inaccurate control of the rotation angle. This allows the optical calibration plate 200 to quickly become parallel to the X-axis and Y-axis of the measuring machine.

[0082] The X-axis adjustment mechanism 400 is connected to the substrate 100 and is used to drive the substrate 100 and the optical verification plate 200 to move along the X-axis so that the light source point of the probe to be verified is located at the center of the edge of the central frame 210 in the X direction.

[0083] The X-axis adjustment mechanism 400 is connected to the substrate 100. When the X-axis adjustment mechanism 400 moves, it will drive the substrate 100 and the optical verification plate 200 to move along the X direction. The center frame 210 of the optical verification plate 200 moves along the X direction. By continuously moving the optical verification plate 200, the light source point of the probe to be verified can be located at the center of the edge of the center frame 210 in the X direction.

[0084] The Y-axis adjustment mechanism 500 is connected to the X-axis adjustment mechanism 400 and is used to drive the optical verification plate 200 to move along the Y-axis so that the light source point of the probe to be verified is located at the center of the edge of the central frame 210 in the Y direction.

[0085] The Y-axis adjustment mechanism 500 and the X-axis adjustment mechanism 400 are connected. When the Y-axis adjustment mechanism 500 moves, it will drive the X-axis adjustment mechanism 400, the substrate 100 and the optical verification plate 200 to move along the Y direction. The center frame 210 of the optical verification plate 200 moves along the Y direction. By continuously moving the optical verification plate 200, the light source point of the probe to be verified can be located at the center of the edge of the center frame 210 in the Y direction.

[0086] The X-axis adjustment mechanism 400 and the Y-axis adjustment mechanism 500 can ensure that the light source point of the probe to be calibrated is aligned with the center point of the center frame 210.

[0087] By setting the X-axis adjustment mechanism 400 and the Y-axis adjustment mechanism 500 in cooperation, the optical calibration plate 200 can be precisely controlled to move along the X and Y directions. There will be no problem of position deviation or excessive or insufficient position movement during the movement. This allows the center point of the center frame 210 of the optical calibration plate 200 to be quickly aligned with the light source point of the probe to be calibrated, achieving a rapid alignment effect.

[0088] The Z-axis adjustment mechanism 600 is connected to the Y-axis adjustment mechanism 500 and is used to drive the optical verification plate 200 to move along the Z-axis.

[0089] The Z-axis adjustment mechanism 600 drives the optical calibration plate 200 to move up and down, which can change the distance between the optical calibration plate 200 and the probe to be calibrated in the Z-axis. By continuously adjusting the distance in the Z-axis, the calibration plate can be adjusted to the clearest state in the display window.

[0090] In some embodiments of this application, the substrate 100 is provided with:

[0091] A fixing part 110 passes through the optical verification plate 200 and is rotatably connected to the optical verification plate 200;

[0092] And an arc-shaped sliding part 120 is disposed opposite to the fixed part 110.

[0093] The fixing part 110 is a fixing protrusion or fixing shaft fixed on the substrate 100. An insertion hole is provided on the optical verification plate 200. The fixing part 110 passes through the insertion hole so that the optical verification plate 200 can rotate relative to the substrate 100 along the fixing part 110.

[0094] A limiting flange is provided on the fixing part 110 to prevent the optical calibration plate 200 from coming out of the fixing part 110.

[0095] The arc-shaped sliding part 120 is an arc-shaped sliding groove provided on the substrate 100.

[0096] The rotation adjustment assembly 300 includes:

[0097] A toggle element 310 is slidably disposed within the arc-shaped sliding portion 120, passing through the optical calibration plate 200.

[0098] The actuating element 310 includes a first actuating section 311 and a second actuating section 312 connected to the first actuating section 311, wherein the outer diameter of the first actuating section 311 is smaller than the outer diameter of the second actuating section 312.

[0099] The second actuating section 312 is inserted into the arc-shaped sliding part 120 to slide along the arc-shaped sliding part 120. Setting the outer diameter of the second actuating section 312 to be large can ensure its structural strength and prevent breakage when the arc-shaped sliding part 120 of the stove slides.

[0100] External threads are provided on the first actuating section 311.

[0101] The locking member 320 is sleeved on the actuating member 310, located above the optical verification plate 200, and is threadedly connected to the actuating member 310.

[0102] The locking element 320 is a locking sleeve with an internal threaded hole, which is fitted onto the first actuating section 311 and threadedly connected to the first actuating section 311.

[0103] When adjusting the optical calibration plate 200, loosen the locking member 320, and drive the optical calibration plate 200 to rotate along the fixed part 110 by sliding the toggle member 310 along the arc-shaped sliding part 120.

[0104] After the locking member 320 is loosened, it will not press the optical verification plate 200. At this time, a force can be applied to the actuating member 310 to make it slide along the arc-shaped sliding part 120, causing the optical verification plate 200 sleeved on it to rotate relative to the substrate 100, changing its position for adjustment.

[0105] When the calibration plate is adjusted to the correct position, tighten the locking member 320 to press and fix the optical calibration plate 200 onto the substrate 100.

[0106] After the optical calibration plate 200 is rotated to the adjustment position, the locking member 320 is screwed on to press it onto the optical calibration plate 200, thus firmly locking and fixing the optical calibration plate 200 in the locked position.

[0107] In some embodiments of this application, the X-axis adjustment mechanism 400 includes:

[0108] The first base 410 is a first base, and a first accommodating space 412 is formed inside it;

[0109] The first lead screw 420 is disposed within the first base 410 and within the first receiving space 412.

[0110] The first threaded component 430 connected to the substrate 100 is threadedly engaged with the first lead screw component 420 and is connected to the substrate 100.

[0111] The first threaded component 430 is located within the first receiving space 412 and is sleeved on the first lead screw component 420.

[0112] A first sliding limiting structure is provided on the first base 410 and the first threaded component 430 to limit the rotation of the first threaded component 430, so that the first threaded component 430 moves along the first base 410 in the X direction.

[0113] When making X-axis adjustments, the first screw lever can be rotated to drive the first threaded component 430 to make a spiral linear motion. However, due to the limitation of the first sliding limit structure, the first threaded component 430 can only move along the X-axis, driving the connected substrate 100 to move in the X-axis.

[0114] By adopting the threaded adjustment method of the first lever and the first threaded part 430, the adjustment of the moving distance of the optical calibration plate 200 is more precise, and there will be no problem of over-adjustment or under-adjustment, which allows the optical calibration plate 200 to be quickly adjusted into place.

[0115] In some embodiments of this application, the first sliding limiting structure includes:

[0116] A first sliding groove 411 is formed on the first substrate 410;

[0117] And a first sliding part 431 is formed on the first threaded part 430 and is slidably disposed in the first sliding groove 411.

[0118] Two first sliding grooves 411 are provided, respectively formed on both sides of the first receiving space 412. Two first sliding parts 431 are provided, symmetrically arranged on both sides of the first threaded member 430, respectively inserted into the first sliding grooves 411 on both sides of the first receiving space 412. When the first threaded member 430 moves along the first lead screw member 420, it can slide smoothly by being guided by the two first sliding parts 431 on both sides, thus ensuring the smoothness of adjustment.

[0119] In some embodiments of this application, a first bearing is provided at one end of the first base 410, one end of the first lead screw 420 is rotatably connected to the first bearing, and the other end extends out of the first base 410, with a first rotating operating part 421 formed on the part extending out of the first base 410.

[0120] The first bearing enables a rotatable connection between the first lead screw 420 and the first base 410. The first rotary operation part 421 is a first rotary handle part, which is used to grip and rotate the first lead screw 420 for adjustment.

[0121] In some embodiments of this application, the first sliding part 431 includes a straight section and an arc-shaped section connected to the end of the straight section. The outer surface of the arc-shaped section is an arc-shaped surface. By inserting the straight section into the first sliding groove 411, the first sliding part 431 can be ensured to slide smoothly along the first sliding groove 411. By contacting the inner wall of the first sliding groove 411 with the arc-shaped surface, the friction between the first sliding groove 411 and the first sliding part 431 can be reduced, making the sliding smoother and more stable.

[0122] In some embodiments of this application, the Y-axis adjustment mechanism 500 includes:

[0123] Second base 510; the second base 510 is a second base, and a second accommodating space 512 is formed inside it.

[0124] And a second lead screw 520 arranged in the second base 510, the second lead screw 520 being disposed in the second receiving space 512;

[0125] The second threaded component 530, connected to the substrate 100, is threadedly engaged with the second lead screw component 520 and connected to the first base 410.

[0126] The second sliding limit structure is provided on the second base 510 and the second threaded member 530, and is used to limit the rotation of the second threaded member 530, so that the second threaded member 530 moves along the second base 510 in the Y direction.

[0127] When making Y-axis adjustments, the second screw lever can be rotated to drive the second threaded component 530 to make a spiral linear motion. However, due to the limitation of the second sliding limit structure, the second threaded component 530 can only move along the Y-axis, causing the first base 410 connected to it to move in the Y-axis.

[0128] By adopting the threaded adjustment method of the second lever and the second threaded part 530, the adjustment of the moving distance of the optical verification plate 200 is more precise, and there will be no problem of over-adjustment or under-adjustment. This allows the Y-axis center position of the center frame 210 of the optical verification plate 200 to be quickly aligned with the light source point of the test head.

[0129] In some embodiments of this application, the second sliding limiting structure includes:

[0130] A second sliding groove 511 is formed on the second substrate 510;

[0131] And a second sliding part is formed on the second threaded part 530 and is slidably disposed in the second sliding groove 511.

[0132] Two second sliding grooves 511 are provided, respectively formed on both sides of the second receiving space 512. Two second sliding parts are provided, symmetrically arranged on both sides of the second threaded member 530, respectively inserted into the second sliding grooves 511 on both sides of the second receiving space 512. When the second threaded member 530 moves along the second lead screw member 520, it can slide smoothly by being guided by the two second sliding parts on both sides, ensuring the smoothness of adjustment.

[0133] In some embodiments of this application, a second bearing is provided at one end of the second base 510, and one end of the second lead screw 520 is rotatably connected to the second bearing, while the other end extends out of the second base 510, and a second rotating operating part 521 is formed on the part of the lead screw extending out of the second base 510.

[0134] The second bearing enables a rotatable connection between the second lead screw 520 and the second base 510. The second rotation operation part 521 is a second rotation handle part, which is used to grip and rotate the second lead screw 520 for adjustment.

[0135] In some embodiments of this application, the Z-axis adjustment mechanism 600 includes:

[0136] Mounting bracket 610;

[0137] And a movable seat 620, which is connected to the second base 510 and is disposed opposite to the fixed seat 610, forming a receiving space between it and the fixed seat 610, and an operating handle 640 is provided on the movable seat 620;

[0138] An elastic element 630 is arranged between the fixed base 610 and the movable base 620;

[0139] Positioning component 650 is used to position the movable seat 620 when it is moved into place.

[0140] The elastic element 630 is a spring, which can be connected at one end to the bottom of the movable base 620 and at the other end to the fixed base 610.

[0141] During adjustment, the movable seat 620 can be moved up or down by applying force to the operating handle 640, thereby adjusting the position of the movable seat 620 in the Z direction. After the movable seat 620 is moved up or down into place, it can be locked and fixed by the positioning component 650.

[0142] By applying force to the movable seat 620 through the operating handle 640, the elastic element 630 is compressed, thereby realizing the Z-axis position adjustment of the movable seat 620, making the adjustment operation more convenient and faster.

[0143] Furthermore, compared with the existing method of adjusting the Z-axis position of the optical calibration plate 200 and the probe to be calibrated by moving the probe to be calibrated, the adjustment method in this embodiment is to move the optical calibration plate 200, which makes the adjustment more convenient.

[0144] In some embodiments of this application, a sliding groove 621 is formed on the movable seat 620 along the height direction of the movable seat 620;

[0145] The positioning component 650 includes:

[0146] Positioning plate 651 is fixed on the fixing base 610;

[0147] The positioning element 652 passes through the positioning plate 651 and is inserted into the sliding groove 621, and is threadedly connected to the positioning plate 651.

[0148] When adjusting the movable seat 620, screw the positioning part 652 away from the bottom wall of the sliding groove 621;

[0149] After the movable seat 620 is adjusted to the correct position, the positioning component 652 is screwed on so that it abuts against the bottom wall of the sliding groove to limit the movable seat 620.

[0150] The positioning component 652 is a positioning bolt or positioning screw, which is threadedly connected to the positioning plate 651. When it is necessary to move the moving seat 620, the positioning component 652 can be unscrewed outward so that it does not abut against the bottom wall of the sliding groove 621, thus allowing the moving seat 620 to move up and down.

[0151] After the movable seat 620 is adjusted to the correct position, the movable seat 620 can be fixed by tightening the positioning part 652 so that its bottom abuts against the bottom wall of the sliding groove 621.

[0152] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
