Description

Technical Field

[0001] The utility model relates to the technical field of microscope, projector and imager measurement calibration test, in particular to a glass line ruler auxiliary adjustment device. Background Art

[0002] In the process of using glass linear scale to verify and calibrate the displacement indication error of instruments such as universal tool microscope, measuring microscope, projector and image measuring instrument, it is necessary to first adjust and align the glass linear scale placed on the workbench, and then the metrological verification and calibration work of the instrument can be carried out.

[0003] The adjustment and alignment of the glass line ruler consists of three parts: Figure 1 First, align the auxiliary alignment "-" lines at both ends of the glass line scale with the "-" level of the calibration crosshairs in the instrument eyepiece field of view, and then refer to Figure 2 , align the scale lines of the glass wire scale with the "I" level of the calibration crosshairs in the instrument's eyepiece field of view, and finally make the scale lines of the glass wire scale at the front, middle and back ends all at the best imaging position in the instrument's eyepiece field of view.

[0004] The preliminary alignment adjustment of the glass scale is the most time-consuming part of the entire instrument measurement work. It requires repeated horizontal and vertical micro-movement of the glass scale to make alignment adjustments to ensure the accuracy of verification and calibration.

[0005] In order to realize the rapid alignment process of the glass wire ruler with the calibration crosshairs in the field of view of the instrument eyepiece, the prior art adopts some positioning and adjustment devices to realize the rapid positioning of the glass wire ruler. These positioning fixtures are usually composed of an adjustment mechanism and a fixture with a receiving cavity. The glass wire ruler is placed in the receiving cavity for positioning, and the position of the fixture is adjusted by the adjustment mechanism so that the calibration crosshairs of the glass wire ruler are aligned. For example, the patent with publication number CN216523656U discloses a glass wire ruler positioning device. The glass wire ruler is placed in the receiving cavity, the length and width of the glass wire ruler are limited by the receiving cavity, and then the glass wire ruler is positioned by the adjusting mechanism. The adjustment mechanism causes the glass linear ruler to rotate horizontally to achieve the alignment process. However, since this adjustment device needs to clamp the glass linear ruler through the cavity, it has certain requirements on the length specification of the glass linear ruler to be placed. The length of the glass linear ruler needs to match the length of the cavity before it can be placed. Therefore, the above-mentioned patent can only position a glass linear ruler with a length of 200 mm. The glass linear ruler often has different length specifications depending on the object of its calibration and verification, and the fixed cavity obviously cannot accommodate glass linear rulers of different length specifications, resulting in certain limitations and an inability to adjust glass linear rulers of different length specifications.

Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the utility model, unless otherwise specified, "plurality" means two or more.

[0029] Example

[0030] like Figures 3 to 7As shown, the embodiment of the utility model provides a glass line scale auxiliary adjustment device, including two placement seats 1, at least two groups of first adjustment mechanisms and second adjustment mechanisms; the two placement seats 1 are horizontally collinearly arranged, and placement grooves 11 are provided on the side walls directly facing the two placement seats 1; at least two groups of first adjustment mechanisms are respectively arranged in the two placement grooves 11, and the first adjustment mechanism includes a first linear motion component 2, a first clamping plate 3 and a first elastic abutment component 4, the first linear motion component 2 is arranged along the first direction of the placement groove 11, and the output end of the first linear motion component is connected to the first clamping plate 3, so as to drive the first clamping plate 3 to move along the placement groove 11. The first elastic abutment component 4 moves in the first direction of the placement groove 11, and the first elastic abutment component 4 is arranged on the opposite side of the first clamping plate 3; the second adjustment mechanism includes a second linear motion component 5, a second clamping plate 6 and a second elastic abutment component 7, the second linear motion component 5 is arranged in one of the placement grooves 11, and the second linear motion component 5 is arranged along the second direction of the placement groove 11, and the second direction is perpendicular to the first direction. The output end of the second linear motion component is connected to the second clamping plate 6, which is used to drive the second clamping plate 6 to move along the second direction of the placement groove 11, and the second elastic abutment component 7 is arranged in another placement groove 11 and is located on the opposite side of the second clamping plate 6.

[0031] In this embodiment, refer to Figure 5It should be noted that the first direction recorded actually refers to the direction in which the glass line ruler moves forward and backward in the placement groove 11, and the second direction recorded actually refers to the direction in which the glass line ruler moves left and right in the placement groove 11. Therefore, when adjusting the glass line ruler to align with the calibration crosshairs in the field of view of the instrument eyepiece, first put the two ends of the glass line ruler into the placement grooves 11 opened on the two placement seats 1. When it is necessary to horizontally align the "one" line at the head and end of the glass line ruler with the horizontal line in the calibration crosshairs, the first adjustment mechanism provided in each placement groove 11 is used to adjust the forward and backward movement position of the glass line ruler. Specifically, the first straight-line moving component 2 drives the first clamping plate 3 to move along the first direction of the placement groove 11, and at the same time, the first elastic abutment component 4 cooperates to realize elastic clamping of the front and rear sides of the glass line ruler, so that the first straight-line moving component 2 continues to move to drive the glass line ruler to move forward and backward fine-tuning until the "one" line at the head and end of the glass line ruler is aligned horizontally with the horizontal line in the calibration crosshairs. The second adjusting mechanism is used to adjust the left and right movement positions of the glass line ruler. Specifically, the second linear moving component 5 drives the second clamping plate 6 to move along the second direction of the placement groove 11, and the second elastic abutting component 7 cooperates with the second elastic abutting component 7 to realize elastic clamping of the left and right sides of the glass line ruler, so that the second linear moving component 5 continues to drive the glass line ruler to move for left and right fine-tuning, until the scale line of the glass line ruler is vertically aligned with the vertical line of the calibration crosshairs. Since the adjustment process is carried out in an elastic clamping manner, the glass line rulers of different lengths can be adjusted and aligned. Therefore, in the metrological verification and calibration work of instruments such as universal tool microscopes, measuring microscopes, projectors and impact measuring instruments, the glass line rulers of different lengths can be adjusted and aligned without being restricted by the length of the glass line ruler.

[0032] Specifically, Figure 7 and Figure 8 As shown, the structure of the first linear motion component 2 is the same as that of the second linear motion component 5. The first linear motion component 2 includes a first shaft body 21, a first internally threaded sleeve 23 and a first rotating portion 24. One side of the first shaft body 21 is an optical axis section, and the other side of the first shaft body 21 is a threaded section. The optical axis section is provided with a first limiting groove 22 arranged along its axial direction. The placement seat 1 is provided with a through hole for the first shaft body 21 to pass through. A first limiting column is fixed in the through hole. The optical axis section is fixed to the first clamping plate 3 after passing through the through hole. The first limiting column is slidably connected in the first limiting groove 22. The first internally threaded sleeve 23 is threadedly sleeved on the threaded section, and one end of the first internally threaded sleeve 23 is rotatably connected to the outer wall of the placement seat 1. The first rotating portion 24 is connected to the other end of the first internally threaded sleeve 23 for driving the first internally threaded sleeve 23 to rotate.

[0033] When the first clamping plate 3 is driven to move forward and backward by the first linear motion component 2, the first internal threaded sleeve 23 is driven to rotate by rotating the first rotating part 24, and the rotation of the first internal threaded sleeve 23 drives the threaded section on the first shaft body 21 to move. Since the first limiting groove 22 opened on the optical axis section of the first shaft body 21 is limited by the first limiting column, when the first internal threaded sleeve 23 is rotated, the first shaft body 21 can only move along the direction of the first limiting groove 22, thereby driving the first clamping plate 3 to translate. Since the second linear motion component 5 has the same structure as the first linear motion component 2, the process of the second linear motion component 5 driving the second clamping plate 6 to move left and right is the same as the above principle.

[0034] Further, as an optional implementation of the first rotating portion 24 , the first rotating portion 24 in this embodiment is a rotating handle or a rotating wheel, which is fixed on the outer wall of the first internally threaded sleeve 23 .

[0035] Furthermore, in order to facilitate installation and allow the first internally threaded sleeve 23 to rotate, a first cylindrical boss 25 is fixed on the outer wall of the first internally threaded sleeve 23 close to one end of the placement seat 1, and a first bearing seat 26 is fixed on the outer wall of the placement seat 1 facing the first cylindrical boss 25. The first cylindrical boss 25 is located in the first bearing seat 26 and is rotatably connected to the first bearing seat 26.

[0036] Furthermore, the thread profile of the threaded section of the first shaft body 21 is triangular or sawtooth-shaped. This configuration enables the threaded section to have a self-locking function and to offset the reaction force given by the elastic abutment component.

[0037] Specifically, the structure of the first elastic abutment component 4 is the same as that of the second elastic abutment component 7. The first elastic abutment component 4 includes a butt plate 41 and a spring 42. The front side of the butt plate 41 is arranged parallel to and opposite to the first clamping plate 3. One end of the spring 42 is connected to the back side of the butt plate 41, and the other end of the spring 42 is connected to the groove wall of the placement groove 11.

[0038] Furthermore, in order to reduce the friction between the front and rear sides of the glass linear scale and the first clamping plate 3 and the abutment plate 41 when the glass linear scale moves forward and backward to achieve horizontal alignment and then moves left and right to achieve vertical alignment, a smooth wear-resistant layer is provided on the contact surface of the abutment plate 41 and the contact surface of the glass linear scale and the first clamping plate 3 and the glass linear scale. The wear-resistant layer is made of a material such as melamine resin.

[0039] Furthermore, there are at least two springs 42 which are arranged in parallel, so as to increase the elastic clamping force.

[0040] like Figure 8 and Fig. 9As shown, in another embodiment of the utility model, in order to achieve clear focus of the engraved lines, two sets of height adjustment mechanisms are also included, which are arranged one by one at the bottom of the two placement seats 1 for adjusting the height of the placement seats 1. The height adjustment mechanism includes a support seat 81, a second shaft body 83, a second internal threaded sleeve 85, a second bearing seat 87 and a second rotating portion 88. A positioning sleeve 82 is fixed to the top of the support seat 81, and a second limiting column is arranged inside the positioning sleeve 82. One side of the second shaft body 83 is an optical axis section, and the other side of the second shaft body 83 is a threaded section, and a second limiting column arranged along its axial direction is opened at the optical axis section. Groove 84, the optical axis section is slidably inserted into the positioning sleeve 82, the second limiting column is slidably connected to the second limiting groove 84, the second internal threaded sleeve 85 is threadedly sleeved on the threaded section, and one end of the second internal threaded sleeve 85 is rotatably connected to the outer wall of the placement seat 1, a second cylindrical boss 86 is fixed on the outer wall of one end of the second internal threaded sleeve 85, the second bearing seat 87 is fixed to one end of the positioning sleeve 82 away from the support seat 81, the second cylindrical boss 86 is sleeved in the second bearing seat 87, and is rotatably connected to the second bearing seat 87, the second rotating portion 88 is connected to the other end of the second internal threaded sleeve 85, and is used to drive the first internal threaded sleeve 23 to rotate.

[0041] When fine-tuning of the focus is required, it can be achieved by adjusting the height of the placement seat 1 through the height adjustment mechanism. The specific adjustment process is as follows: the second internal threaded sleeve 85 is driven to rotate by rotating the second rotating portion 88, and the rotation of the second internal threaded sleeve 85 drives the threaded section on the second shaft body 83 to move. Since the second limiting groove 84 opened on the optical axis section of the second shaft body 83 is limited by the second limiting column, when the second internal threaded sleeve 85 is rotated, the second shaft body 83 can only move vertically along the direction of the second limiting groove 84, thereby driving the placement seat 1 to rise and fall.

[0042] At the same time, during the entire measurement and adjustment process, you need to adjust the focus first, and then adjust the horizontal and vertical alignment operations. The normal calibration is to place the glass line ruler on the stage of the imager, but this stage is not necessarily flat, so it will cause the focal length of the entire glass line ruler to be inconsistent. Therefore, two sets of height adjustment mechanisms are set to solve the problem of focus adjustment. The focus adjustment range is very small. First adjust the focus, and then adjust the horizontal and vertical alignment, so it will not affect the horizontal and vertical. In addition, the focus adjustment ensures that the elastic abutment components on the left and right ends of the glass line ruler can still clamp and fix the glass line ruler when it is tilted.

[0043] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
