[0001] This utility model relates to the field of lens technology, and in particular to a lens mount fixture. Background Technology

[0002] In the production process of mirrorless lenses, production information needs to be laser-printed on the lens mount. However, due to the different sizes of lens mounts, multiple sets of fixtures are required to fix the lens mounts, necessitating repeated line changes and adjustments, which increases production costs. Specifically, the lens mount has positioning holes, but the distance between these holes and the center of the lens mount varies for different sizes. Therefore, how to adapt a single fixture to different lens mount sizes, simplify the line-changing printing process, and reduce production costs is a problem that needs to be solved by those in the field. Utility Model Content

[0003] The purpose of this utility model is to provide a lens mount fixture that can be adapted to different lens mount specifications by adjusting a single fixture, simplifying the process of changing the printing information and reducing production costs.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Lens mount fixture, including:

[0006] A fixed base, with at least two sets of adjustment components spaced apart along its circumference, each set of adjustment components being slidably disposed on the fixed base along its radial direction;

[0007] An adjustment disc is rotatably mounted within the fixed base. The adjustment disc has at least two guide channels, each corresponding to an adjustment component. A portion of the adjustment component passes through the fixed base and extends into the corresponding guide channel. The adjustment disc rotates relative to the fixed base, and through the guide channels, it drives each set of adjustment components to move synchronously along the radial direction of the fixed base toward or away from the center of the fixed base, in order to position the lens mount of the corresponding size.

[0008] Alternatively, each of the guide channels is spiral-shaped, and the distance from one end of the guide channel to the central axis of the adjusting disc gradually increases or decreases.

[0009] Optionally, the adjustment assembly includes a guide pin, a slider, and a positioning pin. The slider is slidably disposed within the fixed base. The guide pin and the positioning pin are respectively disposed on opposite sides of the slider. The guide pin passes through the fixed base and extends into the corresponding guide channel. The positioning pin can be inserted into the positioning hole of the lens mount.

[0010] Optionally, at least two guide grooves are evenly arranged circumferentially on the top of the fixed base, each guide groove extending radially along the fixed base, the slider being provided in a one-to-one correspondence with the guide groove, and being able to move in the guide groove along the length direction of the guide groove.

[0011] The bottom of the guide groove is provided with an adjustment elongated hole that extends along the length of the guide groove. The guide pin passes through the adjustment elongated hole and can move along the length of the adjustment elongated hole.

[0012] Optionally, the bottom of the fixing base is provided with a receiving groove, the opening of the receiving groove is opposite to the guide groove, the adjusting plate is rotatably disposed in the receiving groove, and the adjusting elongated hole is connected to the receiving groove.

[0013] Optionally, the lens mount fixture may also include a lever, and the receiving groove has an adjustment port on its side. One end of the lever is connected to the adjustment plate, and the other end extends out of the adjustment port, and the lever can move within the adjustment port.

[0014] Optionally, a central groove is provided at the top center of the fixing base, and each set of guide grooves is connected to the central groove.

[0015] Optionally, the lens mount fixture also includes a top cover, which is disposed on the top of the fixing base. A sliding channel is provided through the top cover, and the sliding channel is provided one-to-one with the adjustment component. The extension direction of the sliding channel is consistent with the sliding direction of the corresponding adjustment component. A part of the structure of the adjustment component passes through the corresponding sliding channel and extends out of the sliding channel, and can move along the length direction of the sliding channel.

[0016] Optionally, the lens mount fixture may also include a base plate, with the fixing cover located outside the adjustment disc and fixed to the base plate.

[0017] Alternatively, the adjustment assembly is provided in three sets, with the three sets of adjustment assemblies being equally spaced along the circumference of the fixed base; the adjustment disc is provided with three guide channels.

[0018] The beneficial effects of this utility model are:

[0019] In this invention, the rotation of the adjusting disc controls the synchronous movement of the adjusting component within the fixed base. This allows the adjusting component to move radially toward or away from the center of the fixed base, thereby altering the distance between the end of the adjusting component used to fix the lens mount and the center of the fixed base. This makes it suitable for different lens mount sizes. By controlling the position of the adjusting component through the rotation of the adjusting disc, this invention solves the problem of adapting to different sizes of lens mounts where the distance between the positioning hole and the center of the lens mount varies. This not only expands the scope of application, enabling a single fixture to fix multiple lens mount sizes, but also further simplifies the process of changing printing information, thus reducing production costs.

[0038] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0040] like Figures 1-4As shown, this embodiment provides a lens mount fixture, including a base plate 10, a fixing seat 20, an adjusting disc 30, a lever 40, an adjusting assembly 50, and a top cover 60. Optionally, in this embodiment, the fixing seat 20 is fixed to the base plate 10, and the fixing seat 20 covers the outside of the adjusting disc 30 to restrict the position of the adjusting disc 30, so that the adjusting disc 30 can rotate smoothly without falling off. Specifically, the adjusting disc 30 is rotatably disposed within the fixing seat 20, and one end of the lever 40 is connected to the adjusting disc 30, while the other end extends out of the side of the fixing seat 20, so that the operator can rotate the adjusting disc 30 by using the lever 40, making the operation simpler.

[0041] Furthermore, in this embodiment, at least two sets of adjustment components 50 are spaced apart along the axial direction on the fixed base 20, and each set of adjustment components 50 is slidably disposed on the fixed base 20 along the radial direction. The top cover 60 is placed on the top of the fixed base 20 to limit the adjustment components 50, so that the adjustment components 50 can slide smoothly within the fixed base 20 without falling off. Specifically, part of the structure of the adjustment component 50 passes through the fixed base 20 and extends into the adjustment disk 30. Thus, by rotating the adjustment disk 30 with the lever 40, when the adjustment disk 30 rotates relative to the fixed base 20, it can drive each set of adjustment components 50 to move synchronously along the radial direction of the fixed base 20 toward or away from the center of the fixed base 20, so as to position the lens mount 100 of the corresponding size, realize the fixation of lens mounts 100 of different specifications for laser printing of information, expand the scope of application, and at the same time, multiple sets of adjustment components 50 can fix the lens mount 100 at multiple points, improving the stability during the printing process. Specifically, a portion of the structure of the adjustment component 50 extends through and out of the upper cover 60 and can be inserted into the positioning hole 101 of the lens mount 100, thereby fixing the lens mount 100.

[0042] For example, in this embodiment, a locking device may also be provided at the lever 40 or the adjustment dial 30 so that after the position of the adjustment component 50 is adjusted, the position of the lever 40 is locked to prevent the position of the adjustment component 50 from moving. The locking device can be set as needed, and will not be described in detail here.

[0043] like Figure 5 As shown, in this embodiment, the base plate 10 is a square plate, and the base plate 10 is provided with a first fixing hole 11 to facilitate the connection of the fixing seat 20. Combined with... Figure 7 As shown, in this embodiment, the bottom of the fixing base 20 is provided with a second fixing hole 204, and the first fixing hole 11 and the second fixing hole 204 are provided one-to-one to ensure the stable installation of the fixing base 20 on the base plate 10. Furthermore, the base plate 10 is also provided with several fastening holes, and the base plate 10 can be fixed to the laser engraving machine table by screws to realize the printing of information of the lens mount 100.

[0044] like Figure 6 and Figure 7 As shown, in this embodiment, at least two guide grooves 21 are evenly arranged circumferentially on the top of the fixed base 20, and each guide groove 21 extends radially along the fixed base 20. The adjustment component 50 is also arranged in a one-to-one correspondence with the guide groove 21, so that when the adjustment disk 30 rotates, the adjustment component 50 can move in the guide groove 21 along the length direction of the guide groove 21, that is, along the radial direction of the fixed base 20 toward or away from the center of the fixed base 20, thereby realizing the change of the distance between the fixed end of the adjustment component 50 and the center of the fixed base 20, which is suitable for the installation of lens mounts 100 of different sizes.

[0045] Specifically, the bottom of the guide groove 21 is provided with an adjustment elongated hole 202 through the fixed base 20, and the adjustment elongated hole 202 extends along the length direction of the guide groove 21. Thus, a portion of the structure of the adjustment component 50 passes through the adjustment elongated hole 202 and then extends into the adjustment plate 30, allowing it to move within the adjustment elongated hole 202 along its length direction to avoid interference with the movement of the adjustment component 50. For example, the length direction of the adjustment elongated hole 202 is the same as the length direction of the guide groove 21, both arranged radially along the fixed base 20, ensuring the synchronous movement of the entire adjustment component 50. Optionally, in this embodiment, three sets of adjustment components 50 are provided, and the three sets of adjustment components 50 are equally spaced along the circumference of the fixed base 20. Correspondingly, three guide grooves 21 and three adjustment elongated holes 202 are also provided. In other embodiments, the position and number of these three components can be set as needed or according to the distribution differences of the positioning holes 101 on the lens mount 100, which will not be elaborated here.

[0046] like Figure 6 As shown, in this embodiment, a central groove 22 is provided at the center of the top of the fixing base 20, and each set of guide grooves 21 is connected to the central groove 22, thereby ensuring the smooth movement of the adjustment component 50 and avoiding restriction of the adjustment component 50 during movement. Furthermore, an avoidance groove 23 is also provided on the circumferential side of the top of the fixing base 20 to ensure the smooth placement and removal of the lens mount 100.

[0047] Exemplarily, the top of the mounting base 20 is also provided with a first hole 2031 and a second hole 2032 for connection to the upper cover 60. (Combined) Figure 9As shown, the upper cover 60 is provided with a third hole 603 and a fourth hole 604, wherein the third hole 603 corresponds to the first hole 2031, and the fourth hole 604 corresponds to the second hole 2032, thereby achieving a stable connection between the upper cover 60 and the fixing base 20. Exemplarily, it is also possible to connect only the third hole 603 and the first hole 2031, using the fourth hole 604 and the second hole 2032 for positioning, to achieve quick docking between the fixing base 20 and the upper cover 60. This can be configured as needed and will not be elaborated further.

[0048] like Figure 7 As shown, in this embodiment, the bottom of the fixed base 20 is provided with a receiving groove 24, and the opening of the receiving groove 24 is positioned away from the guide groove 21. The adjusting plate 30 is rotatably disposed in the receiving groove 24, and the adjusting elongated hole 202 communicates with the receiving groove 24. Thus, the adjusting component 50 can pass through the adjusting elongated hole 202 and connect to the adjusting plate 30 located in the receiving groove 24. Specifically, the side of the receiving groove 24 is provided with an adjusting port 201, and the lever 40 can extend out of the adjusting port 201 and move within the adjusting port 201 to facilitate operation by the operator.

[0049] like Figure 8 As shown, in this embodiment, at least two guide channels 301 are provided on the adjusting disk 30, and the guide channels 301 are corresponding one-to-one with the adjusting components 50, so as to ensure that when the adjusting disk 30 rotates, it can drive all the adjusting components 50 to move simultaneously. Specifically, each group of guide channels 301 is spiral-shaped, and the distance from one end of the guide channel 301 to the other end from the central axis of the adjusting disk 30 gradually increases or decreases, to satisfy the arrangement of the Archimedean spiral. Further, part of the structure of the adjusting component 50 extends into the corresponding guide channel 301, and when the adjusting disk 30 rotates, it can drive each group of adjusting components 50 to move radially along the fixed base 20 through the guide channel 301. For example, the rotation angle of the adjusting disk 30 is proportional to the movement distance of the adjusting component 50 in the guide groove 21 of the fixed base 20, thereby realizing the uniform movement of the adjusting component 50 radially within the fixed base 20. Correspondingly, three guide channels 301 are also provided.

[0050] Furthermore, the side of the adjusting disc 30 is cut with a mounting surface, and the mounting surface is set as a plane. A mounting hole 302 is provided on the mounting surface along the radial direction of the adjusting disc 30. One end of the lever 40 is connected to the mounting hole 302 to achieve stable installation of the lever 40 on the adjusting disc 30 and to ensure that the adjusting disc 30 can rotate clockwise or counterclockwise around the central axis when the lever 40 is driven. Specifically, the mounting hole 302 is provided with an internal thread, and the lever 40 is screwed into the mounting hole 302.

[0051] like Figure 4As shown, the adjustment assembly 50 includes a guide pin 51, a slider 52, and a positioning pin 53. Both the guide pin 51 and the positioning pin 53 are tightly connected to the slider 52 to ensure the mechanical strength of the adjustment assembly 50. Specifically, the slider 52 is slidably disposed within the fixed base 20. The guide pin 51 and the positioning pin 53 are respectively disposed on opposite sides of the slider 52, located at both ends of the slider 52. Thus, the guide pin 51 passes through the fixed base 20 and extends into the corresponding guide channel 301, and the positioning pin 53 can pass through the top cover 60 and be inserted into the positioning hole 101 of the lens mount 100, thereby achieving stable installation of the adjustment assembly 50.

[0052] Specifically, in this embodiment, both the guide pin 51 and the positioning pin 53 are cylindrical structures, and at least the end of the positioning pin 52 is spherical to facilitate smooth insertion into the positioning hole 101 without causing abrasion or damage to the lens mount 100. Furthermore, the slider 52 and the guide groove 21 are arranged in a one-to-one correspondence, and the guide pin 51 is inserted into the guide channel 301 after passing through the adjustment elongated hole 202. Thus, when the adjustment disc 30 rotates, the guide pin 51 can move along its extension direction within the guide channel 301, driving the slider 52 to move synchronously. This allows the slider 52 to move radially along the fixed base 20 within the guide groove 21, thereby changing the distance between the positioning pin 53 and the center of the fixed base 20. This adapts to lens mounts 100 with different center distances in the positioning holes 101, thus achieving an adjustable function for the lens mount fixture, suitable for lens mounts 100 of different sizes and specifications.

[0053] like Figure 9 As shown, in this embodiment, at least two sliding channels 601 are provided from top to bottom on the upper cover 60, and the sliding channels 601 are corresponding one-to-one with the adjustment components 50. Specifically, the positioning pin 53 in the adjustment component 50 passes through the corresponding sliding channel 601 and extends out of the sliding channel 601 to be inserted into the positioning hole 101. Further, when the adjustment disk 30 rotates, the positioning pin 53 can move in the sliding channel 601 along the extension direction of the sliding channel 601, and the extension direction of the sliding channel 601 is consistent with the sliding direction of the corresponding adjustment component 50, thereby ensuring that its movement is not interfered with while adapting to the position of the positioning hole 101 of the lens mount 100 of different sizes. Exemplarily, three sliding channels 601 are also provided, and they are evenly distributed along the circumference of the upper cover 60. Furthermore, a clearance opening 602 is provided on the circumferential side of the top cover 60, and the clearance opening 602 is provided in a one-to-one correspondence with the clearance groove 23 of the fixing seat 20 to ensure smooth loading and unloading of the lens mount 100.

[0054] Working process: Assemble the adjustment plate 30 and lever 40, and place the adjustment plate 30 on the base plate 10; then cover the outside of the adjustment plate 30 with the fixing seat 20 containing the adjustment component 50, so that the lever 40 extends out of the adjustment port 201 and the guide pin 51 extends into the guide channel 301; then cover the top cover 60, so that the positioning pin 53 passes through and extends out of the sliding channel 601; finally, according to the distance between the positioning hole 101 on the lens mount 100 to be printed and the center of the lens mount 100, adjust the adjustment plate 30 by rotating the lever 40, so that the distance between the positioning pin 53 and the center of the fixing seat 20 matches it, and then lock the position of the lever 40 or the adjustment plate 30, then place the lens mount 100 so that the positioning pin 53 can be inserted into the positioning hole 101, complete the installation of the lens mount 100, perform laser printing of information, and finally repeat the above steps with different specifications of lens mount 100.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here.
