Description

Technical Field

[0001] This utility model relates to the field of integrated lens barrel processing technology, specifically to a fixture for cleaning and coating integrated lens barrels. Background Technology

[0002] As a core component of optical instruments, the cleanliness of the inner and outer walls and the uniformity of the coating of the integrated lens barrel directly affect the imaging quality of the optical system. During the production process, the lens barrel needs to undergo strict cleaning and coating treatment, and the positioning accuracy and adaptability of the fixture, as the positioning carrier, are crucial to ensuring the processing quality.

[0003] Existing lens barrel fixtures are mostly of fixed size and can only be used for a single specification of lens barrel. When processing lens barrels of different sizes, it is necessary to change to the corresponding fixture, which is not only cumbersome and time-consuming, but also may cause positioning reference deviation due to frequent changes, affecting the accuracy of cleaning and coating. Utility Model Content

[0004] In view of the problems existing in the above-mentioned fixtures for cleaning and coating of integrated lens barrels, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a fixture for cleaning and coating integrated lens barrels, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixture for cleaning and coating an integrated lens barrel includes a base plate, a fixed L-shaped block, and a movable L-shaped block. The fixed L-shaped block is fixedly disposed at one corner of the upper surface of the base plate, and the movable L-shaped block is slidably disposed at another corner of the upper surface of the base plate. A first strip-shaped opening is provided on the upper surface of the base plate between the fixed L-shaped block and the movable L-shaped block. A sliding rod is fixedly disposed inside the first strip-shaped opening. A slider is movably sleeved on the wall of the sliding rod. The upper side of the slider is fixedly connected to the movable L-shaped block. A rotating rod is rotatably disposed on the lower surface of the base plate on the side away from the slider. A pushing mechanism for moving the slider is provided on the wall of the rotating rod. A transmission mechanism for driving the rotating rod to rotate is provided on the upper surface of the base plate.

[0008] Preferably, the pushing mechanism includes a push rod and a pin. The push rod is fixedly sleeved on the wall of the rotating rod. The wall of the push rod has a second slot. The pin is rotatably disposed on the lower side of the slider, and the lower end of the pin passes through the second slot.

[0009] Preferably, the transmission mechanism includes a gear and a rack. The gear is fixedly sleeved on the upper end of the rotating rod, and the rack is meshed on one side of the gear. A threaded rod is threaded inside the rack, and both ends of the threaded rod are rotatably connected to side plates. One side of the side plate is fixedly connected to the base plate.

[0010] Preferably, a limit rod is provided parallel to one side of the threaded rod, and both ends of the limit rod are fixedly connected to the corresponding side plate.

[0011] Preferably, the longitudinal section of both the slider and the first strip opening is rectangular, and both sides of the slider abut against the inner wall of the groove.

[0012] Preferably, the lower end of the round pin is fixedly sleeved with an anti-detachment ring.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model uses a rotating rod to drive a push rod to rotate, which in turn causes the push rod to move a round pin. This causes the round pin to move a slider along a sliding rod, thereby moving the movable L-shaped block relative to the fixed L-shaped block. This facilitates efficient and labor-saving positioning of integrated lens barrels of different specifications.

[0015] 2. In this utility model, by rotating the threaded rod, the rack moves, and the rack drives the gear to rotate, thereby stably driving the rotating rod to rotate. At the same time, because the transmission of the threaded rod has self-locking properties, it can maintain the stability of the position of the movable L-shaped block after adjustment.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a fixture for cleaning and coating an integrated lens barrel.

[0025] Example 1

[0026] Reference Figure 1-4 A fixture for cleaning and coating an integrated lens barrel includes a base plate 1, a fixed L-shaped block 2, and a movable L-shaped block 3. The fixed L-shaped block 2 is fixedly disposed at one corner of the upper surface of the base plate 1, and the movable L-shaped block 3 is slidably disposed at the other corner of the upper surface of the base plate 1. A first strip-shaped opening is provided on the upper surface of the base plate 1 between the fixed L-shaped block 2 and the movable L-shaped block 3. A sliding rod 5 is fixedly disposed inside the first strip-shaped opening. A slider 6 is movably sleeved on the wall of the sliding rod 5. The longitudinal section of both the slider 6 and the first strip-shaped opening is rectangular. Both sides of the slider 6 abut against the inner wall of the groove, so that the slider 6 cannot rotate, i.e., it can slide stably. The upper side of the slider 6 is fixedly connected to the movable L-shaped block 3. A rotating rod 7 is rotatably disposed on the lower surface of the base plate 1 on the side away from the slider 6. A pushing mechanism for moving the slider 6 is provided on the wall of the rotating rod 7. A transmission mechanism for driving the rotating rod 7 to rotate is provided on the upper surface of the base plate 1.

[0027] Example 2

[0028] Reference Figure 1-4 The pushing mechanism includes a push rod 8 and a round pin 9. The push rod 8 is fixedly sleeved on the rod wall of the rotating rod 7. The rod wall of the push rod 8 has a second slot. The round pin 9 is rotatably set on the lower side of the slider 6. The lower end of the round pin 9 passes through the second slot. The lower end of the round pin 9 is fixedly sleeved with an anti-detachment ring to prevent the round pin 9 from slipping out of the second slot as much as possible.

[0029] Example 3

[0030] Reference Figure 1-4The transmission mechanism includes a gear 12 and a rack 10. The gear 12 is fixedly sleeved on the upper end of the rotating rod 7. The rack 10 is meshed on one side of the gear 12. A threaded rod 13 is threaded inside the rack 10. Both ends of the threaded rod 13 are rotatably connected to side plates 11. One side of the side plate 11 is fixedly connected to the base plate 1. A limit rod 4 is provided parallel to one side of the threaded rod 13. Both ends of the limit rod 4 are fixedly connected to the corresponding side plate 11, so that the rack 10 cannot rotate, that is, it can slide stably.

[0031] In this invention, when positioning the integrated lens barrel, the lens barrel is placed on the base plate 1, with one corner abutting against the inner wall of the fixed L-shaped block 2 as a positioning reference. The threaded rod 13 is rotated. Since the rack 10 is threadedly connected to the threaded rod 13 and is restricted from rotation by the limiting rod 4, the rack 10 moves along the direction of the limiting rod 4. The rack 10 meshes with the gear 12, driving the gear 12 and the rotating rod 7 to rotate. When the rotating rod 7 rotates, the push rod 8 on its rod wall rotates synchronously. The second slot on the push rod 8 engages with the round pin 9, pushing the round pin 9 to move... The round pin 9 drives the slider 6 to slide along the slide bar 5 (the slider 6 with a rectangular cross section cooperates with the first strip opening to ensure stable sliding). The slider 6 drives the movable L-shaped block 3 to move closer to the fixed L-shaped block 2 until the inner side wall of the movable L-shaped block 3 is in close contact with the other corner of the lens barrel, thus completing the clamping and positioning of the lens barrel. The anti-disengagement ring prevents the round pin 9 from slipping out of the second strip opening, ensuring the reliability of the transmission. Since the threaded transmission of the threaded rod 13 has self-locking properties, the movable L-shaped block 3 can maintain a stable position after positioning, preventing the lens barrel from loosening during cleaning or coating.

[0032] When it is necessary to change to a different size lens barrel, rotate the threaded rod 13 in the opposite direction. The rack 10 drives the gear 12 to rotate in the opposite direction, and the rotating rod 7 and push rod 8 rotate in the opposite direction. The round pin 9 pulls the slider 6 and the movable L-shaped block 3 away from the fixed L-shaped block 2. After releasing the lens barrel, the new lens barrel can be inserted. Repeat the above steps to complete the positioning. The whole process does not require changing the fixture. The movable L-shaped block can be accurately moved by adjusting the threaded rod, which can adapt to the positioning requirements of different sized lens barrels. The operation is time-saving and labor-saving, and effectively improves the work efficiency of cleaning and coating.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
