Description

Technical Field

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

[0002] One step in optical lens manufacturing involves sealing the lens mount with adhesive using a dispensing machine. This process requires a fixture to secure the lens mount, which is then fixed to the three-jaw chuck of the dispensing machine. Currently, the fixture for securing the lens mount typically uses positioning pins that engage with holes on the lens mount to position it. A detachable locking mechanism then presses the lens mount firmly onto the fixture, preventing movement during the sealing process. However, this method requires operators to install or remove the locking mechanism each time the lens mount is sealed, resulting in low production efficiency.

[0003] CN201920694800 discloses an infrared lens mount housing fixture, including a worktable. A first positioning pin is mounted on the upper surface of the worktable. A second positioning pin is mounted on one side of the first positioning pin. A third positioning pin is mounted on one side of the second positioning pin. A fourth positioning pin is mounted on one side of the third positioning pin. A fifth positioning pin is mounted on one side of the fourth positioning pin. A sixth positioning pin is mounted on one side of the fifth positioning pin. A threaded hole is provided on the inner side of the worktable. A connecting cylinder is mounted below the worktable. A workpiece is mounted above the workpiece. A pressure cap is mounted above the pressure cap. A rubber ring is mounted below the pressure cap. A nut is mounted above the pressure cap. An anti-slip sleeve is fitted on the outer side of the nut. The pressure cap is connected to the worktable via a connecting rod, and one end of the connecting rod is threaded. This fixture uses multiple locating pins to position the workpiece, and then uses a combination of a pressure cap and a connecting rod to press the pressure cap onto the workpiece, thereby fixing the workpiece. However, this method requires the pressure cap to be installed and removed in each processing operation, resulting in low production efficiency.

[0004] The technical problem that this utility model needs to solve is: how to improve the production efficiency of lens mounts in the sealing process. Utility Model Content

[0005] The main purpose of this utility model is to provide a lens mount fixing fixture. The lens mount is positioned by a positioning pin, and an elastic clamping module is set on the side of the receiving groove. When the operator places the lens mount in the receiving groove, the elastic clamping module elastically deforms along the axial direction of the through hole, generating an elastic compressive force. This allows the elastic clamping module to automatically clamp the side of the lens mount, thereby completing the positioning and fixing of the lens mount, reducing operation steps and improving production efficiency.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A lens mount fixing fixture includes a base and an elastic clamping module; the base has a receiving groove for placing the lens mount, a plurality of positioning posts are vertically arranged on the bottom surface of the receiving groove, and a through hole is provided on the side surface of the receiving groove, the through hole extending horizontally in the axial direction; the elastic clamping module is connected in the through hole and partially extends into the receiving groove, the elastic clamping module is used to press the side surface of the lens mount with elastic force.

[0008] Preferably, the elastic clamping module includes a sliding rod, an elastic element, and a fixing element; the sliding rod, elastic element, and fixing element are arranged sequentially in the through hole along the direction away from the receiving groove; the axis of the sliding rod extends axially along the through hole, and the sliding rod portion extends into the receiving groove to clamp the lens mount; the outer circumferential surface of the sliding rod is provided with a coaxially arranged annular support boss, which is connected in the through hole; along the axial direction of the through hole, one end of the elastic element contacts the end face of the annular support boss, and the other end contacts the end face of the fixing element; the fixing element is connected to the end of the through hole away from the receiving groove.

[0009] Preferably, the fixing element is a set screw; the through hole includes a smooth section and a threaded section arranged sequentially in a direction away from the receiving groove, and the smooth section and the threaded section are connected; the annular support boss is slidably connected to the smooth section; the fixing element is threadedly connected to the threaded section.

[0010] Preferably, the inner wall of the through hole facing the receiving groove is provided with an annular limiting boss. The annular limiting boss is coaxially arranged with the through hole, and the annular limiting boss cooperates with the annular supporting boss to limit the extension length of the sliding rod from the through hole to the receiving groove.

[0011] Preferably, a clamping block is provided on the side of the sliding rod facing the receiving groove, and the clamping block is located inside the receiving groove; the shape of the clamping block is hemispherical or frustum-shaped; the axis of the clamping block extends along the axial direction of the through hole.

[0012] Preferably, the outer surface of the clamping block is covered with a buffer layer.

[0013] Preferably, both the base and the sliding rod are made of plastic.

[0014] Preferably, the bottom side of the base is provided with a mounting boss.

[0015] Compared with existing technologies, this solution has the following advantages:

[0016] The fixing fixture in this case first positions the lens mount using locating pins. Then, an elastic clamping module is installed on the side of the receiving groove. When the operator places the lens mount into the receiving groove, the side of the lens mount contacts the elastic clamping module, causing the elastic clamping module to elastically deform along the axial direction of the through hole. The lens mount can then be placed in the receiving groove. At this time, the elastic clamping module has an elastic compressive force, causing it to press against the side of the lens mount, thus fixing the lens mount in place. In this way, the operator only needs to place the lens mount normally into the receiving groove for fixing. When it is necessary to remove the lens mount, only the lens mount needs to be pulled out; no operation on the elastic clamping module is required, reducing the operator's steps and improving production efficiency.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Example 1

[0024] refer to Figure 1-4A lens mount 3 fixing fixture includes a base 1 and an elastic clamping module 2. The base 1 is provided with a receiving groove 11 for placing the lens mount 3. A plurality of positioning posts 12 are vertically provided on the bottom surface of the receiving groove 11. A through hole 13 is provided on the side surface of the receiving groove 11, and the through hole 13 extends horizontally in the axial direction. The elastic clamping module 2 is connected in the through hole 13 and extends partially into the receiving groove 11. The elastic clamping module 2 is used to clamp the side surface of the lens mount 3 with elastic force.

[0025] In this embodiment, the bottom of the lens mount 3 is provided with a mounting base 31. The mounting base 31 is square in shape, and mounting holes 32 are provided at each of the four corners of the mounting base 31. The shape of the receiving groove 11 matches the shape of the mounting base 31, and the position of the positioning post 12 corresponds to the position of the mounting hole 32. The through hole 13 is located in the middle of two adjacent mounting holes 32.

[0026] The specific operating procedure of this fixing fixture is as follows: The operator aligns the mounting hole 32 and the positioning post 12, and places the mounting base 31 of the lens mount 3 into the receiving groove 11. At this time, the side of the mounting base 31 contacts the elastic clamping module 2. The operator applies a slightly larger downward pressure to the lens mount 3. Due to the pressure, the elastic clamping module 2 elastically deforms along the axial direction of the through hole 13, allowing the operator to place the mounting base 31 into the receiving groove 11. Simultaneously, the elastic clamping module 2 generates a spring compression force. Due to the elastic compression force, the end of the elastic clamping module 2 presses against the side of the mounting base 31, thereby fixing the lens mount 3. When it is necessary to remove the lens mount 3, simply pull it out.

[0027] Preferably, the elastic clamping module 2 includes a sliding rod 21, an elastic element 22, and a fixing element 23; the sliding rod 21, the elastic element 22, and the fixing element 23 are arranged sequentially in the through hole 13 in a direction away from the receiving groove 11; the axis of the sliding rod 21 extends axially along the through hole 13, and part of the sliding rod 21 extends into the receiving groove 11 to press against the lens mount 3; the outer peripheral surface of the sliding rod 21 is provided with a coaxially arranged annular support boss 211, and the annular support boss 211 is connected in the through hole 13; along the axial direction of the through hole 13, one end of the elastic element 22 contacts the end face of the annular support boss 211, and the other end contacts the end face of the fixing element 23; the fixing element 23 is connected to the end of the through hole 13 away from the receiving groove 11.

[0028] In this embodiment, the end of the sliding rod 21 extends into the receiving groove 11 through the through hole 13. By providing an annular support boss 211, it can not only contact the elastic element 22, but also reduce the friction between the sliding rod 21 and the through hole 13. The elastic element 22 is a spring.

[0029] The specific working process of the elastic clamping module 2 is as follows: During the process of placing the mounting base 31 of the lens mount 3 into the receiving groove 11, after the mounting base 31 contacts the end of the sliding rod 21, the operator applies pressure to the lens mount 3. Due to the pressure, the sliding rod 21 slides away from the receiving groove 11. During the sliding process, the annular support boss 211 compresses the elastic element 22, thereby generating an elastic compressive force in the elastic element 22. After the lens mount 3 is installed, the end of the sliding rod 21 will press against the side of the mounting base 31. Moreover, the elastic element 22 provides elastic force to the annular support boss 211, so that the sliding rod 21 remains in a clamping state against the mounting base 31.

[0030] Preferably, the fixing member 23 is a set screw; the through hole 13 includes a smooth section 131 and a threaded section 132 arranged sequentially in a direction away from the receiving groove 11, and the smooth section 131 and the threaded section 132 are connected; the annular support boss 211 is slidably connected to the smooth section 131; and the fixing member 23 is threadedly connected to the threaded section 132.

[0031] In this embodiment, the fixing member 23 is threadedly connected to the threaded section 132, which not only ensures that the elastic member 22 can be supported when compressed, but also allows the elastic force of the elastic member 22 to be adjusted by adjusting the screwing depth of the fixing member 23. In addition, the smooth section 131 is set to contact the annular support boss 211, so that the sliding rod 21 can slide smoothly within the through hole 13.

[0032] Preferably, the inner wall of the through hole 13 facing the receiving groove 11 is provided with an annular limiting boss 133. The annular limiting boss 133 is coaxially arranged with the through hole 13. The annular limiting boss 133 and the annular supporting boss 211 cooperate to limit the extension length of the sliding rod 21 from the through hole 13 to the receiving groove 11.

[0033] In this embodiment, an annular limiting boss 133 is provided. When the elastic member 22 generates elastic force after being compressed, the elastic member 22 will push the sliding rod 21 to move in the direction toward the receiving groove 11 by pushing the annular support boss 211. The annular limiting boss 133 will block the annular support boss 211, thereby preventing the sliding rod 21 from being too long from the part of the sliding rod 21 extending from the through hole 13 into the receiving groove 11, and thus preventing the sliding rod 21 from breaking when the lens mount 3 is placed next time.

[0034] Secondly, the position of the annular support boss 211 on the sliding rod 21 can be set according to the required length of the sliding rod 21 extending from the through hole 13 to the receiving groove 11, thereby controlling the extension length of the sliding rod 21 when the annular support boss 211 contacts the annular limiting boss 133.

[0035] Preferably, the sliding rod 21 has a clamping block 212 on the side facing the receiving groove 11, and the clamping block 212 is located inside the receiving groove 11; the clamping block 212 is hemispherical or frustum-shaped; the axis of the clamping block 212 extends along the axial direction of the through hole 13.

[0036] In this embodiment, the clamping block 212 is the portion of the sliding rod 21 that extends into the receiving groove 11, and the sliding rod 21 contacts the side of the mounting base 31 through the clamping block 212. During design, it is necessary to ensure that the clamping block 212 extends completely into the receiving groove 11, or that a portion of the clamping block 212 is still within the through hole 13. The clamping block 212 is preferably hemispherical, but a frustum shape can also be chosen as needed. By setting the outer peripheral surface of the clamping block 212 to an arc shape, a guide surface is formed. After the mounting base 31 contacts the clamping block 212, as the mounting base 31 continues to move downwards, the clamping block 212 can smoothly move axially along the through hole 13 and retract into the through hole 13, thereby allowing the mounting base 31 to be placed within the receiving groove 11, reducing the probability of the sliding rod 21 being broken by the mounting base 31.

[0037] Preferably, the outer surface of the clamping block 212 is covered with a buffer layer.

[0038] In this embodiment, the buffer layer can be made of polyurethane or rubber. By setting the buffer layer, the side of the mounting base 31 can be prevented from being scratched by the clamping block 212.

[0039] Preferably, both the base 1 and the sliding rod 21 are made of plastic.

[0040] In this embodiment, the lens mount 3 is made of aluminum alloy. By using a plastic base 1 with a sliding rod 21, the fixing fixture can be prevented from scratching the lens mount 3.

[0041] Preferably, the bottom side of the base 1 is provided with a mounting boss 14.

[0042] In this embodiment, the peripheral dispensing machine is equipped with a three-jaw chuck. The lens mount 3 is fixed and positioned by a fixing fixture. Then, the fixing fixture is connected to the three-jaw chuck of the peripheral dispensing machine by a mounting boss 14, so that the dispensing head of the dispensing machine can operate the lens mount 3.
