Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and specifically to a pressure head assembly for lens processing. Background Technology

[0002] In the field of lens processing, the pressure head assembly, as a core tooling device, plays a decisive role in the processing quality and efficiency of lenses. Lens processing involves multiple delicate steps such as grinding and polishing. During this process, it is not only necessary to accurately fix the lens, but also to apply appropriate pressure according to the characteristics of the lens to ensure the stability of the lens position at each processing stage, thereby ensuring processing accuracy and surface quality.

[0003] However, current pressure head assemblies for lens processing have certain shortcomings in terms of clamping space adjustment. Many pressure heads use a fixed structure with a fixed clamping space size, making it impossible to flexibly adjust according to differences in lens thickness, shape, etc. When dealing with lenses of different thicknesses, it is difficult to provide a suitable clamping space. If the clamping space is too large, the lens is prone to shaking during processing, resulting in scratches on the lens surface, reduced precision, and seriously affecting product quality; if the clamping space is too small, the lens may break due to excessive compression, causing material waste and increasing production costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a pressure head assembly for lens processing.

[0005] To achieve the above objectives, this application discloses a pressure head assembly for lens processing, including a connecting seat, a base at the lower end of the connecting seat, a stud at the middle part of the base, an outer sleeve at the outer end of the stud by means of a thread, the lower end of the outer sleeve extending to the outside of the stud, and a placement space for accommodating a lens is formed between the end face of the outer sleeve and the stud.

[0006] The outer sleeve is a plastic sleeve, and a metal sleeve is fitted onto the lower end face of the plastic sleeve.

[0007] The lower end of the plastic sleeve extends to the outside of the metal sleeve.

[0008] A pressure ring is fitted on the inner end of the stud near the outer sleeve. One end of the pressure ring contacts the outer sleeve, and the other end contacts and engages with a spring fitted on the stud.

[0009] The outer sleeve has a serrated protrusion on the side facing the pressure ring, and the pressure ring has a groove that matches the serrated protrusion.

[0010] The lens processing pressure head assembly proposed in this application includes a connecting seat, a base at the lower end of the connecting seat, and a stud in the middle of the base. The outer end of the stud is threadedly connected to an outer sleeve, the lower end of which extends outward from the stud, forming a space for accommodating the lens. In use, the operator can easily and precisely adjust the size of the space by simply rotating or replacing the outer sleeve, quickly adapting to the processing needs of lenses of different thicknesses. This assembly effectively solves the problem of difficult adjustment of the clamping space in pressure head assemblies, bringing an efficient, stable, and cost-effective solution to the lens processing industry.

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] Example 1: As Figure 1-3 As shown, a pressure head assembly for lens processing is disclosed. This assembly functions to fix, position, and apply pressure to the lens during processing, ensuring the accuracy and quality of the lens processing. In this embodiment, the pressure head assembly specifically includes a connecting seat 1, which connects the pressure head assembly to external processing equipment (such as a lens grinding machine, with a threaded connection). Through the connecting seat, the power generated by the external equipment and the pressure provided by the pressure head assembly can be combined to make the lens fit against the mold below, and the lens processing operation can be achieved by the oscillation of the mold below.

[0018] The lower end of the connecting seat 1 is provided with a base 2, and the middle part of the base 2 is provided with a stud 3. The base 2 is an intermediate support structure, providing a stable foundation for the installation of the stud. The outer end of the stud 3 is threadedly connected to an outer sleeve 4. The outer end of the stud has threads, and the threaded connection with the outer sleeve enables a detachable connection between the two. The threaded connection not only facilitates the installation and removal of the outer sleeve, making it easy to maintain and replace components, but also allows the relative position between the outer sleeve and the stud to be adjusted by rotating the outer sleeve according to actual processing needs. The lower end of the outer sleeve 4 extends to the outside of the stud 3, and a placement space 5 for accommodating the lens is formed between the end face of the outer sleeve 4 and the stud 3. A rubber ring is provided on the end face of the stud 3 to buffer the collision between the lens and the end face. The outer sleeve is threadedly connected to the stud, and its lower end extends to the outside of the stud. A placement space 5 is formed between the end face of the outer sleeve and the stud, which is specifically used to accommodate the lens to be processed. The design and dimensions of the outer tube determine the size and shape of the placement space, thus accommodating lenses of different specifications and sizes. The placement space is the area enclosed by the end faces of the outer tube and the stud, and its function is to provide a stable placement position for the lens. During lens processing, the lens is placed within this space, and the pressure head assembly applies appropriate pressure to ensure that the lens does not shift during processing, thereby guaranteeing processing accuracy.

[0019] Example 2: As Figure 3 As shown, the outer sleeve 4 is a plastic sleeve, and a metal sleeve 6 is fitted onto the lower end face of the plastic sleeve. Plastic possesses a certain degree of flexibility and elasticity. During lens processing, when the pressure head assembly applies pressure to the lens, the plastic sleeve can buffer the pressure to a certain extent, preventing damage to the lens due to excessive pressure. Compared to rigid materials such as metal, plastic adheres better to the lens surface, reducing scratches and wear, and helping to protect the lens's optical performance and appearance quality.

[0020] During lens manufacturing, the lower surface of the outer sleeve frequently comes into contact with and rubs against the lens or other processing components. Prolonged use may lead to excessive internal stress, causing overall deformation and making it difficult to hold the lens in place. A metal sleeve, with its high rigidity, fitted over the plastic sleeve, prevents this problem from occurring.

[0021] Furthermore, the lower end of the plastic sleeve extends to the outside of the metal sleeve 6. The protruding plastic portion acts as a buffer before the lens comes into direct contact with the metal sleeve. When the pressure head assembly contacts the lens, the protruding plastic portion contacts the lens first, further dispersing the pressure and preventing the metal sleeve from directly squeezing the lens, thereby better protecting the lens from damage.

[0022] Example 3: As Figure 1-5As shown, a pressure ring 7 is fitted onto the inner end of the stud 3 near the outer sleeve 4. One end of the pressure ring 7 contacts the outer sleeve 4, and the other end engages with the spring 8 fitted onto the stud 3. The pressure ring 7 is an intermediate component for pressure transmission and adjustment. When the spring 8 deforms and generates elastic force, the pressure ring transmits the spring force to the outer sleeve 4, thereby applying pressure to the outer sleeve 4 to keep it stable and reduce the possibility of the outer sleeve 4 loosening.

[0023] The outer sleeve 4 has a serrated protrusion 9 on the side facing the pressure ring 7, and the pressure ring 7 has a corresponding groove 10 on the serrated protrusion 9. The serrated structure increases the contact area and friction between the outer sleeve 4 and the pressure ring 7, making their connection tighter. This ensures that the relative position between the outer sleeve 4 and the pressure ring 7 is accurately fixed. Simultaneously, the cooperation between the serrated protrusion and the groove ensures accurate positioning between the outer sleeve 4 and the pressure ring 7. During lens processing, when the outer sleeve 4 is subjected to pressure from the spring and the pressure ring, this cooperative structure prevents the outer sleeve 4 from rotating relative to the pressure ring 7, thereby ensuring the stability and accuracy of the placement space 5 and avoiding any impact on the lens processing precision due to outer sleeve rotation.

[0024] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
