Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical lens processing technology, and specifically relates to a lens clamp. Background Technology
[0002] In lens processing, there is a high-temperature dyeing step that requires a dyeing machine. The conventional method involves clamping two lenses in the same fixture. This fixture includes a support frame and clamps on either side of the support frame. Each clamp has an upper clamp and a lower clamp. The lower clamp is fixed, while the upper clamp can slide up and down along the support frame. The sliding of the upper clamp clamps tightens or loosens the lens positioned between the upper and lower clamps. However, in existing fixtures, the two upper clamps move synchronously up and down, while the lens is vertically mounted between the clamps. If the two lenses are mounted separately, the first lens is prone to falling off when the second lens is installed. Mounting both lenses simultaneously reduces the risk of falling to some extent, but increases the installation difficulty. Furthermore, springs are installed between the upper clamp supports, using spring force to press the upper clamps downwards onto the lens. During the high-temperature dyeing process, the lens is easily deformed due to heat and pressure, affecting the pass rate of the high-temperature dyeing. Summary of the Invention
[0003] The purpose of this invention is to provide a lens clamp to solve at least one of the technical problems of existing lens clamps, which easily lead to lens falling off and deformation during high-temperature dyeing operations.
[0004] To achieve the above objectives, the technical solution of this utility model includes:
[0005] A lens clamp includes a support and two sets of clamp assemblies disposed on both sides of the support. Each clamp assembly includes a movable clamp and a fixed clamp. The relative position direction of the movable clamp and the fixed clamp is defined as the Z-axis direction. The two movable clamps are respectively connected to the support through an adjustment mechanism. The movable clamps are connected to the support in a manner that allows them to move along the Z-axis direction by means of the adjustment mechanism, thereby enabling the clamp assembly to clamp or release the lens.
[0006] In one embodiment, the adjustment mechanism is provided with a locking structure, by means of which the movable clamp is held in a certain position on the bracket, thereby clamping the lens.
[0007] In one embodiment, the adjustment mechanism includes an adjustment block fixedly connected to the bracket. The adjustment block has two first adjustment holes extending along the Z-axis. The movable chuck has an adjustment part, and the adjustment parts of the two movable chucks are respectively movably inserted into the first adjustment holes along the Z-axis. The adjustment part has a second adjustment hole. The adjustment block also has a locking operation member, which passes through the first adjustment hole and is inserted into the second adjustment hole. The movable chuck is held at a certain position on the bracket by means of the locking operation member, so that the locking operation member, the adjustment hole, and the adjustment part cooperate to form the locking structure.
[0008] In one embodiment, the second adjustment hole is an elongated hole extending along the Z-axis direction, and the locking operation component is a locking bolt threaded to the adjustment block. The locking bolt is fitted with a pressing block. By locking the locking bolt, the pressing block is pressed onto the adjustment part, thereby pressing the adjustment part against the side wall of the first adjustment hole, and thus keeping the movable chuck in a certain position on the bracket.
[0009] In one embodiment, the adjustment part is a flat plate structure, and the locking operation member is inserted into the second adjustment hole along the thickness direction of the flat plate.
[0010] In one embodiment, the direction in which the two sets of clamp assemblies are arranged opposite each other is defined as the X-axis direction, and the direction perpendicular to the Z-axis direction and the X-axis direction is defined as the Y-axis direction. The bracket extends along the Z-axis direction and includes a support portion and a hanging portion distributed along the Z-axis direction. The hanging portion is used to suspend the lens clamp on an external device. The support portion extends along the plane formed by the Y-axis and the Z-axis, and the hanging portion extends along the plane formed by the X-axis and the Z-axis. The two movable clamps are connected to the support portion through the adjustment mechanism.
[0011] In one embodiment, the bracket is formed by bending a slender metal rod, with both ends of the metal rod fixedly connected to a base between the two fixed clamps. The handle portion is a ring structure formed by bending the metal rod, and the support portion is formed by the two ends of the metal rod spaced apart along the Y-axis. A connecting portion is also provided between the handle portion and the support portion.
[0012] In one embodiment, the direction in which the two movable clamps face each other is defined as inward, and the direction away from each other is defined as outward. The movable clamps are provided with handles that protrude outward.
[0013] In one embodiment, the direction in which the two sets of clamping assemblies are arranged relative to each other is defined as the X-axis direction, and the direction perpendicular to the Z-axis direction and the X-axis direction is defined as the Y-axis direction. The movable clamping head includes two movable jaws spaced apart along the Y-axis direction, and the fixed clamping head includes two fixed jaws spaced apart along the Y-axis direction. The movable jaws are provided with a bent structure protruding away from the fixed jaws, and the fixed jaws are provided with a bent structure protruding away from the movable jaws. Thus, the bent structures of the movable jaws and the bent structures of the fixed jaws cooperate to form a recessed clamping structure, which is used to limit the lens.
[0014] The beneficial effects of this utility model include:
[0015] 1. The movable clamps of the two sets of clamping assemblies are connected to the bracket through an adjustment mechanism, so that the two movable clamps can move up and down independently. Thus, the two clamping assemblies can be operated independently to clamp or release the lens. The two clamping assemblies do not interfere with each other, which can not only clamp the two lenses separately, reducing the difficulty of the lens clamping process, but also prevent the clamping assemblies from affecting the fixation of the other lens when clamping one lens. In other words, it reduces the risk of the clamped lens falling off and improves the convenience and stability of installation.
[0016] 2. The movable chuck is held in a certain position on the bracket by the locking structure, so it will not continuously apply a force toward the fixed chuck to the lens. This can prevent the lens from deforming due to simultaneous heat and pressure in a high-temperature environment, and help maintain the shape of the lens in a high-temperature environment.
[0017] 3. The chuck assembly is set along the X-axis and located on both sides of the support part of the bracket. The support part extends along the plane formed by the intersection of the Y-axis and Z-axis. The hanging handle extends along the plane formed by the X-axis and Z-axis. Thus, when the hanging handle is suspended on external equipment (such as a dyeing machine), the center of gravity of the clamp is on the support part between the two lenses, which helps to maintain the stability of the clamp and prevent the clamp and lenses from tilting.

Detailed Implementation
[0025] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. This utility model is not limited to the descriptions of the following embodiments.
[0026] like Figures 1-6 The image shows one embodiment of the lens clamp of this utility model.
[0027] like Figures 1-4 As shown, a lens clamp in this embodiment includes a bracket 1 and two sets of clamping assemblies 2 disposed on both sides of the bracket 1. The clamping assemblies 2 are used to clamp the lens J. Each set of clamping assemblies 2 includes a movable clamp 21 and a fixed clamp 22. The direction in which the two sets of clamping assemblies 2 are disposed relative to each other is defined as the X-axis direction. The direction in which the movable clamp 21 and the fixed clamp 22 are positioned relative to each other is defined as the Z-axis direction. The direction perpendicular to the Z-axis direction and the X-axis direction is defined as the Y-axis direction.
[0028] The bracket 1 extends along the Z-axis and includes a support portion 11 and a hanging handle portion 12 distributed along the Z-axis. The hanging handle portion 12 is used to suspend the lens clamp on the dyeing machine. The support portion 11 extends along the plane formed by the Y-axis and Z-axis, and the hanging handle portion 12 extends along the plane formed by the X-axis and Z-axis. Two movable clamps 21 are connected to the support portion 11 through an adjustment mechanism 3. In this embodiment, the lens clamp is suspended on the dyeing machine for high-temperature dyeing of lens J. In other embodiments, the lens clamp can be suspended on other external equipment besides the dyeing machine, such as an ultrasonic cleaner, a decolorizing machine, etc.
[0029] The chuck assembly 2 is arranged along the X-axis, and the two movable chucks 21 are located on both sides of the support part 11 of the bracket 1. The support part 11 extends along the plane formed by the intersection of the Y-axis and the Z-axis. The hanging handle part 12 extends along the plane formed by the X-axis and the Z-axis. Thus, when the hanging handle part 12 is suspended on external equipment (such as a dyeing machine), the center of gravity of the clamp is on the support part 11, that is, approximately at the midpoint between the two lenses J, which helps to maintain the stability of the clamp and prevent the clamp and lenses from tilting.
[0030] In this embodiment, the bracket 1 is formed by bending a slender metal rod. The two ends of the metal rod are fixedly connected to a base between two fixed clamps 22. The handle portion 12 is a ring-shaped structure formed by bending the metal rod, specifically a circular ring. The support portion 11 is formed by the two ends of the metal rod spaced apart along the Y-axis. A connecting portion 13 is also provided between the handle portion 12 and the support portion 11. The connecting portion 13 mainly serves as a transition between the handle portion 12 and the support portion 11, ensuring that the handle portion 12 is formed in the middle of the support portion 11 in the Y-axis direction, further maintaining the center of gravity of the clamp at the midpoint between the two lenses J. The bracket structure formed by bending a slender metal rod is simple, resulting in fewer heat storage structures around the lenses J, which is beneficial for the rapid heat dissipation and cooling of the lenses J after high-temperature processing.
[0031] Two movable clamps 21 are connected to the bracket 1 via an adjustment mechanism 3. The movable clamps 3 are connected to the bracket 1 in a way that allows them to move along the Z-axis, thereby enabling the clamp assembly 2 to clamp or release the lens J. When the movable clamps 21 approach the fixed clamps 22 until they press against the lens J, the lens J is clamped. When the movable clamps 21 move away from the fixed clamps 22 until the lens J can be removed from the gap between them, the lens J is released. Furthermore, since the two movable clamps 21 are connected to the bracket 1 via an adjustment mechanism 3, the two movable clamps 21 can move up and down independently. Therefore, the movable clamps 21 of the two clamp assemblies 2 can be adjusted independently to clamp the lens J. The two clamp assemblies 2 do not interfere with each other, which can clamp the two lenses J separately, reducing the difficulty of clamping the lens J. It can also prevent the clamp assembly 2 from affecting the fixation of the other lens J when clamping one lens J, thereby reducing the risk of the clamped lens J falling off and improving the convenience and stability of installation.
[0032] The adjustment mechanism 3 is equipped with a locking structure. The movable chuck 21 is held in a certain position on the bracket 1 by means of the locking structure, thereby clamping the lens J.
[0033] like Figures 5-6As shown, the adjustment mechanism 3 in this embodiment includes an adjustment block 31 fixedly connected to the bracket 1. The adjustment block 31 is fixed to the support portion 11 of the bracket 1 by a set bolt 4. The adjustment block 31 has two first adjustment holes 311 extending along the Z-axis direction. The movable chuck 21 has an adjustment portion 211, and the adjustment portions 211 of the two movable chucks 21 are respectively movably inserted into the first adjustment holes 311 along the Z-axis direction. The adjustment portion 211 has a second adjustment hole 212, which is an elongated hole extending along the Z-axis direction. Block 31 is also equipped with a locking mechanism that passes through the first adjustment hole 311 and is inserted into the second adjustment hole 212. The locking mechanism is a locking bolt 32 threadedly connected to the adjusting block 31. A clamping block 33 is fitted onto the locking bolt 32. By tightening the locking bolt 32, the clamping block 33 is pressed against the adjusting part 211, thereby pressing the adjusting part 211 against the side wall of the first adjustment hole 311. This keeps the movable chuck 21 in a certain position on the bracket 1. Thus, the locking bolt 32, the adjustment hole 212, and the adjusting part 211 cooperate to form a locking structure. The adjusting part 211 is a flat plate structure. The locking bolt 32 is inserted into the second adjustment hole 212 along the thickness direction of the flat plate. The flat plate structure of the adjusting part 211 makes the movable chuck lighter and easier to adjust and fix.
[0034] When the position of the movable chuck 21 needs to be adjusted along the Z-axis, the locking bolt 32 is loosened, allowing the adjusting part 211 of the movable chuck 21 to slide along the first adjusting hole 311. After adjusting to the target position, the locking bolt 32 is tightened, causing the adjusting block 31 to deform until the side wall of the first adjusting hole 311 clamps the adjusting part 211. Since the second adjusting hole 212 is an elongated hole extending along the Z-axis, the locking bolt 32 can remain inserted into the second adjusting hole 212 during the movement of the movable chuck 21. During the tightening and loosening adjustment, only a small rotation of the locking bolt 32 is needed without completely unscrewing it. Furthermore, the cooperation between the second adjusting hole 212 and the locking bolt 32 allows for stepless adjustment of the distance between the movable chuck 21 and the fixed chuck 22, suitable for various lens sizes.
[0035] In another embodiment, the second adjustment hole 212 can also be a plurality of circular holes spaced apart along the Z-axis. The locking bolt 32 can be replaced by a pin. When it is necessary to adjust the movable chuck 21, the pin is pulled out. After the movable chuck 21 is adjusted to the position, the pin is inserted into the corresponding second adjustment hole 212. This adjustment method makes the distance between the movable chuck 21 and the fixed chuck 22 have multiple levels, which reduces the trouble of fine-tuning the distance between the movable chuck 21 and the fixed chuck 22 for less experienced operators.
[0036] In addition to the two adjustment methods mentioned above, in other embodiments different from the two embodiments, the adjustment mechanism 3 can be formed by a gear and rack structure. For example, a gear is provided on the bracket 1, and a rack extending along the Z-axis is provided on the adjustment part 211 of the movable chuck 21. The movable chuck 21 is adjusted by the meshing of the gear and rack, and the movable chuck 21 can be held at a certain position on the bracket 1 by means of the anti-rotation of the gear.
[0037] The position of the movable clamp 21 on the bracket 1 includes not only the position where the movable clamp 21 and the fixed clamp 22 cooperate to clamp the lens J, but also the position where the movable clamp 21 moves away from the fixed clamp 22 and releases the lens J.
[0038] The movable chuck 21 is maintained in a certain position on the bracket 1 by the locking structure, so it will not continuously apply a force toward the fixed chuck 22 to the lens J. This can prevent the lens J from deforming due to simultaneous heating and pressure in a high-temperature environment, which is beneficial to maintaining the shape of the lens J in a high-temperature environment and improving the pass rate of dyeing processing.
[0039] In the X-axis direction, the direction in which the two movable chucks 21 face each other is defined as "inward," and the direction away from each other is defined as "outward." Each movable chuck 21 has a handle 213 protruding outward. The handle 213 facilitates user operation of the movable chucks 21, enabling adjustment of the movable chucks 21 along the Z-axis. Furthermore, the handle 213 also serves to limit the movement of the movable chucks 21. When the clamp is suspended, if the locking structure fails to reliably lock, causing the movable chucks 21 to slide downward, the protruding handle 213, engaging with the first adjustment hole 311, prevents the movable chucks 21 from continuously falling.
[0040] like Figures 1-4 As shown, the movable chuck 21 includes two movable jaws 210 spaced apart along the Y-axis, and the fixed chuck 22 includes two fixed jaws 220 spaced apart along the Y-axis. The movable jaws 210 and fixed jaws 220 are spaced apart along the Y-axis, thus forming a four-point clamping limit for the lens J, improving the reliability of lens J clamping. The movable jaws 210 have a bent structure protruding away from the fixed jaws 220, and the fixed jaws 220 also have a bent structure protruding away from the movable jaws 210. The bent structures of the movable jaws 210 and the fixed jaws 220 cooperate to form a recessed clamping structure, which is used to limit the lens and further improve the stability of lens clamping.
