Description

Technical Field

[0001] This utility model relates to the field of processing and positioning technology, and in particular to a rapid positioning structure for processing optical components. Background Technology

[0002] In routine manufacturing of optical components, CNC machining is commonly used to achieve high precision and reduce the number of setups. During CNC machining, rapid and accurate positioning of the optical component blank is a crucial step in ensuring both machining quality and efficiency.

[0003] Currently, fixtures are typically used to position the billet in the front-to-back direction, while the left-to-right position control relies on the operator's experience or auxiliary positioning methods to ensure that the billet is stable and accurately centered during processing.

[0004] However, existing positioning methods have obvious drawbacks. For example, the common scribing alignment method is simple to operate, but the positioning process relies on manual visual alignment, which is inefficient. Another improvement method is to add positioning screws or positioning pins for limiting, which can improve some operational efficiency, but because the position of the screws or positioning pins is fixed, it can only be used for blanks of a specific length or less, and cannot flexibly adapt to the processing needs of optical components of different sizes, thus greatly limiting its applicability.

[0005] To address this, we propose a rapid positioning structure for optical component processing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid positioning structure for optical component processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a rapid positioning structure for processing optical components, including a vise and a positioning mechanism, wherein a guide hole is provided on the left outer wall of the vise, extending through to the right outer wall; The positioning mechanism includes an assembly base, which is detachably and fixedly connected to the outer right side wall of the vise. A manual transverse movement component is mounted through the assembly base. A slide rod is fixedly sleeved on the movable end of the manual transverse movement component, and the right side of the slide rod is partially slidably inserted into the guide hole. The left outer wall of the slide bar is detachably fixedly connected to a diagonal bar, and the top of the right outer wall of the diagonal bar is detachably fixedly connected to a positioning pin, and the positioning pin matches the clamping step of the vise. The front outer wall of the mounting base is provided with a locking screw that extends into the interior, and the locking screw is threadedly connected to the mounting base and matches the manual lateral movement component.

[0008] Furthermore, a screw hole is provided above and below the guide hole, and the screw hole is opened on the right outer wall of the bench vise, providing a stable and reliable mounting base for the entire positioning mechanism.

[0009] Furthermore, two first hidden grooves are symmetrically opened on the upper and lower sides of the right outer wall of the mounting base. Each of the two first hidden grooves is provided with a first connecting bolt, and the first connecting bolt extends through the inner wall of the first hidden groove to the left side of the mounting base and is threadedly connected to the adjacent screw hole. This structure realizes a compact and detachable connection between the mounting base and the bench vise.

[0010] Furthermore, the manual lateral movement assembly includes a knob, which is located on the right side of the mounting base. A screw is fixedly connected to the left side of the knob, and the mounting base is rotatably sleeved on the outer surface of the screw. The end of the locking screw rubs against the outer wall of the screw. A nut is threaded onto the outer surface of the screw, and a slide rod is fixedly sleeved on the outer surface of the nut. The knob facilitates manual driving of the screw rotation.

[0011] Furthermore, two limiting rings are symmetrically fixedly sleeved on the outer surface of the screw, and the two limiting rings are respectively attached to the left and right sides of the mounting base. The limiting rings axially position the screw to prevent it from moving axially during operation.

[0012] Furthermore, the left outer wall of the inclined rod is provided with three second hidden grooves, and each of the three second hidden grooves is provided with a second connecting bolt. The second connecting bolt extends through the inner wall of the second hidden groove to the right side of the inclined rod. Two of the second connecting bolts are threadedly connected to the slide rod, and the remaining second connecting bolt is threadedly connected to the positioning pin, which can realize the separation of the inclined rod, the positioning rod, and the slide rod.

[0013] The beneficial effects of this utility model are: In use, this utility model connects to the vise via a detachable mounting base and uses a manual lateral movement component to drive the positioning pins on the slide bar and the inclined bar to move laterally. This enables flexible and stepless adjustment of the position of the positioning pins relative to the clamping step of the vise, allowing the structure to quickly adapt to the accurate positioning of optical component blanks of different sizes. It effectively overcomes the shortcomings of the scribing alignment method in the background technology, which is inefficient and the fixed positioning pins have limited applicability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] like Figures 1-6 As shown, a rapid positioning structure for processing optical components is disclosed, including a vise 1 and a positioning mechanism 2. The vise 1 has a guide hole 11 extending through to the right outer wall on its left side. The positioning mechanism 2 includes a mounting base 211, which is detachably fixed to the right outer wall of the vise 1. A screw hole 12 is provided above and below the guide hole 11, and the screw hole 12 is located on the right outer wall of the vise 1. The right outer wall of the mounting base 211 has two first hidden grooves 24 symmetrically arranged vertically. Each of the two first hidden grooves 24 is provided with a first connecting bolt 210, which extends through the inner wall of the first hidden groove 24 to the left side of the mounting base 211 and is threadedly connected to the adjacent screw hole 12. The guide hole 11 is a square hole to ensure subsequent guidance of the slide rod 26.

[0019] The mounting base 211 is fitted with a manual lateral movement assembly. The movable end of the manual lateral movement assembly is fixedly sleeved with a slide rod 26, and the right side of the slide rod 26 is partially slidably inserted into the guide hole 11. The manual lateral movement assembly includes a knob 25, which is located on the right side of the mounting base 211. A screw 27 is fixedly connected to the left side of the knob 25, and the mounting base 211 is rotatably sleeved on the outer surface of the screw 27. A nut 23 is threaded onto the outer surface of the screw 27, and the slide rod 26 is fixedly sleeved on the outer surface of the nut 23. Two limiting rings 29 are symmetrically fixedly sleeved on the outer surface of the screw 27, and the two limiting rings 29 are respectively attached to the left and right sides of the mounting base 211. The thread helix angle of the screw 27 is less than the friction angle, which gives the screw 27 a self-locking capability and can prevent it from shifting due to vibration or load.

[0020] A diagonal rod 22 is detachably fixed to the left outer wall of the slide rod 26, and a positioning pin 21 is detachably fixed to the top of the right outer wall of the diagonal rod 22. The positioning pin 21 matches the clamping step of the bench vise 1. Three second hidden grooves 212 are provided on the left outer wall of the diagonal rod 22. Each of the three second hidden grooves 212 is provided with a second connecting bolt 213. The second connecting bolt 213 extends through the inner wall of the second hidden groove 212 to the right side of the diagonal rod 22. Two of the second connecting bolts 213 are threadedly connected to the slide rod 26, and the remaining second connecting bolt 213 is threadedly connected to the positioning pin 21. A threaded hole is provided at the left end of the positioning pin 21, and two threaded holes are also provided at the left end of the slide rod 26. The threaded holes match the second connecting bolts 213.

[0021] The front outer wall of the mounting base 211 is provided with a locking screw 28 that extends into the interior, and the locking screw 28 is threadedly connected to the mounting base 211. The end of the locking screw 28 rubs against the outer wall of the screw 27. The locking screw 28 is a conventional hand-tightening screw that can be manually tightened for easy operation.

[0022] Working principle: First, insert the slide rod 26 into the guide hole 11. Then, connect the mounting base 211 to the screw hole 12 on the right outer wall of the bench vise 1 through the first connecting bolt 210 to fix the mounting base 211. Finally, the second connecting bolt 213 is used to complete the fixed connection between the diagonal rod 22, the positioning pin 21, and the slide rod 26.

[0023] In use, the lateral position of the positioning pin 21 is adjusted manually using the lateral movement component according to the length of the optical component blank. The operator rotates the knob 25, causing the screw 27 to rotate within the mounting base 211. The rotation of the screw 27 is converted into lateral movement via the nut 23, thereby driving the slide bar 26 to slide left and right along the guide hole 11. The movement of the slide bar 26 is transmitted to the positioning pin 21 via the inclined bar 22, causing the position of the positioning pin 21 relative to the clamping step of the vise 1 to change. This adjustment process requires no tools and can achieve stepless adjustment, adapting to the positioning requirements of blanks of different sizes and ensuring rapid and accurate positioning of the blank in the left and right directions.

[0024] After the locating pin 21 moves to the desired position, tighten the locking screw 28 on the mounting base 211. The end of the locking screw 28 rubs against the outer wall of the screw 27, effectively preventing the screw 27 from rotating unexpectedly and ensuring that the locating pin 21 remains in a fixed position during processing, avoiding displacement due to vibration or external force.

[0025] The entire structure is designed for efficient machining of optical components. Repeated positioning can be achieved through simple manual operation, significantly improving clamping efficiency in CNC machining.

Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
