Description

Technical Field

[0001] The utility model belongs to the technical field of screw-less height-fixing modules, and specifically relates to a height-fixing locking device. Background Art

[0002] Currently, the module industry does not have a screw thread height setting process. The only way to set the height in the industry is to adjust the height column and the base. The standard locking height is achieved by repeatedly adjusting the height of the height adjustment column. The process of adjusting the height of the machine is cumbersome and time-consuming, and the risk factor of height fluctuation is high.

[0003] Chinese patent publication number CN113953154A discloses a jig for assembling a threadless lens, comprising a base, a jig chassis, and a jig gland. The jig chassis is mounted on the base and is provided with a number of mounting holes for mounting a lens motor assembly. The jig chassis also comprises a clamping assembly and a height-fixing assembly. The clamping assembly is provided on both sides of the jig gland. The height-fixing assembly comprises a gland float provided in the jig gland and a gland float cover provided above the gland float. Before use, the jig chassis and the base are first mounted together. Place the lens motor assembly into the mounting hole on the jig chassis, and then use the clamping assembly to press the jig cover and jig chassis to prevent the entire jig from shaking and misalignment. Subsequently, use the height-fixing assembly to fix the height of the lens motor assembly, and then apply glue to fix the height of the lens in the motor, so as to achieve accurate and fast height setting of small batches of threadless lenses. However, the structure of the jig is relatively complex and may be difficult to clean and maintain. In particular, dust and impurities are prone to accumulate in the mounting holes, arc-shaped grooves and other parts, affecting the installation accuracy of the lens motor assembly.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] See also Figure 1-4 As shown, in this embodiment, a fixed locking height device is provided, including: a workbench 1, a base 2 is connected to the surface of the workbench 1, a first fixing hole 4 is opened on the surface of the base 2, the base 2 is connected to the workbench 1 through the first fixing hole 4, a mounting groove 9 is opened in the center of the surface of the base 2, a height adjustment column 7 is provided below the mounting groove 9, and the height adjustment column 7 and the base 2 are an integrated structure, an air outlet 6 is opened on the inner wall of the mounting groove 9, a cover plate 3, which is located above the mounting groove 9, a fixing column 10 is connected to the bottom end of the cover plate 3, a second fixing hole 8 is opened on the bottom end surface of the mounting groove 9, the cover plate 3 is fixedly connected to the base 2 through the fixing column 10 and the second fixing hole 8, and a chip removal groove 5 is opened between the first fixing hole 4 and the second fixing hole 8.

[0030] The workbench 1 provides a support platform for the entire device. The base 2 is connected to the workbench 1 through the first fixing hole 4 to ensure the stability of the base 2 on the workbench 1. The mounting groove 9 in the center of the surface of the base 2 is used to place the lens that needs to be locked and adjusted in height. The height adjustment column 7 below the mounting groove 9 is an integrated structure with the base 2, so that the height adjustment column 7 is fixed in the base 2 and cannot be adjusted, eliminating the problems of long time and low efficiency and height instability in machine modification, improving the modification efficiency and reducing the risk of unstable locking height. The cover plate 3 is fixedly connected to the base 2 through the fixing column 10 and the second fixing hole 8, and can fix the components in the mounting groove 9 after the height is adjusted to avoid shaking or displacement during subsequent operations, ensuring the stability of the locking height. The chip groove 5 can discharge dust and impurities in time to prevent them from accumulating in the device and affecting the accuracy and performance of the device. At the same time, the chip groove 5 also helps to keep the device clean and reduce the difficulty of cleaning and maintenance.

[0031] In this embodiment, the chip groove 5 is opened on the surface of the base 2, and one end of the chip groove 5 is communicated with the mounting groove 9. The chip groove 5 is sloped, and one end located at the mounting groove 9 is the bottom end. The side wall of the base 2 is provided with a connecting hole 13 corresponding to the external air pump. The connecting hole 13 is connected to the air outlet 6, and the connecting hole 13 and the air outlet 6 are in a "Y" shape.

[0032] When dust and impurities accumulate in the mounting groove 9, gas is generated by an air pump, and the gas is discharged from the air outlet 6 through the connecting hole 13, thereby blowing out the dust and impurities in the mounting groove 9. The chip removal groove 5 can improve the efficiency of blowing out the dust and impurities, and the slope shape can facilitate the blowing out of dust and impurities.

[0033] A positioning hole 14 is provided above the first fixing hole 4. The positioning hole 14 is opened at the chip groove 5 and is conical. A positioning column 15 is provided on the surface of the fixing column 10. The positioning column 15 corresponds to the positioning hole 14. The conical design of the positioning hole 14 can play a guiding role when the positioning column 15 is inserted, making the positioning more accurate and faster. When the cover plate 3 is fixedly connected to the base 2, the positioning column 15 is inserted into the positioning hole 14 to ensure that the relative position of the cover plate 3 and the base 2 is accurate, thereby improving the installation accuracy and stability of the device.

[0034] A fixing groove 12 is provided at the bottom end of the cover 3, and a through hole 11 is provided at the top end of the fixing groove 12. The through hole 11 passes through the surface of the cover 3. The fixing groove 12 is used to accommodate the lens located in the mounting groove 9, so that the top end of the lens is against the top end of the inner wall of the fixing groove 12 to achieve better fixing efficiency.

[0035] Working principle:

[0036] Place the workbench 1 in a suitable position as a stable support platform for the entire device. Connect the base 2 to the workbench 1 through the first fixing hole 4 to ensure the stability of the base 2 on the workbench 1. At this time, the mounting slot 9, height adjustment column 7, air outlet 6, chip removal groove 5, connection hole 13 and other structures are all in a ready state. Since the height adjustment column 7 below the mounting slot 9 is an integrated structure with the base 2 and cannot be adjusted, this design eliminates the problems of traditional machine modification such as long time consumption, low efficiency and height instability. Place the lens that needs to be adjusted for locking height in the mounting slot 9. The height of the lens is predetermined by the integrated height adjustment column 7, which improves the efficiency of the machine modification while reducing the risk of unstable locking height.

[0037] The fixing post 10 at the bottom end of the cover plate 3 corresponds to the second fixing hole 8 on the bottom surface of the mounting groove 9. The fixing post 10 is inserted into the second fixing hole 8 to fix the cover plate 3 to the base 2. In this way, the lens can be fixed in the mounting groove 9 after the height is adjusted to avoid shaking or displacement during subsequent operations, thereby ensuring the stability of the locking height. The positioning post 15 provided on the surface of the fixing post 10 corresponds to the conical positioning hole 14 at the chip groove 5 above the first fixing hole 4. When the cover plate 3 is fixedly connected to the base 2, the positioning post 15 is inserted into the positioning hole 14. The conical design of the positioning hole 14 plays a guiding role, making the positioning more accurate and quick, ensuring that the relative position of the cover plate 3 and the base 2 is accurate, and improving the installation accuracy and stability of the device;

[0038] During the use of the device, when dust and impurities accumulate in the installation groove 9, the external air pump is started, and the gas generated by the air pump enters through the connecting hole 13 on the side wall of the base 2. Since the connecting hole 13 and the air outlet 6 are in a "Y" shape, the gas flows smoothly to the air outlet 6. After the gas is discharged from the air outlet 6, the dust and impurities in the installation groove 9 are blown out. At this time, the chip groove 5, which is connected to the installation groove 9 and is in a sloped shape, comes into play. The sloped design facilitates the rapid blowing out of dust and impurities under the push of the gas, thereby improving the efficiency of blowing out dust and impurities. The chip groove 5 can discharge dust and impurities in time to prevent them from accumulating in the device and affecting the accuracy and performance of the device. It also helps to keep the device clean and reduce the difficulty of cleaning and maintenance.

[0039] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention.
