Description

Technical Field

[0001] This utility model relates to the field of machining fixtures, and in particular to a side drilling fixture for optical inspection components. Background Technology

[0002] In the manufacturing process of optical inspection components, side drilling is a crucial step in ensuring the assembly accuracy of optical elements. Traditional side drilling processes for optical inspection components typically employ general-purpose fixtures or manual clamping and positioning, which suffers from insufficient positioning accuracy and low clamping efficiency. Most existing fixtures use a single-plane positioning method, which is insufficient for effectively securing the optical inspection component during drilling, especially for components with double-sided raised edges, where conventional fixtures cannot simultaneously achieve precise positioning on both the sides and below the raised edges. Furthermore, traditional clamping mechanisms often use bolt locking, which is not only cumbersome and time-consuming but also prone to workpiece deformation or positioning misalignment due to uneven clamping force, affecting drilling position accuracy. During drilling, the lack of a dedicated clearance structure makes it easy for the tool path to interfere with the fixture, leading to reduced processing efficiency or even tool damage. Therefore, there is an urgent need to develop a high-efficiency drilling fixture that can achieve rapid and accurate positioning and reliable clamping of optical inspection components, along with tool clearance functionality, to meet the stringent requirements of modern optical manufacturing for processing accuracy and production efficiency.

It has advantages such as accurate positioning, stable clamping, and convenient operation, significantly improving the processing accuracy and production efficiency of side drilling for optical inspection components, and is particularly suitable for mass production needs.

A first positioning support block and a second positioning support block are respectively provided on the left and right sides of the top surface of the mounting base. The sides of the first positioning support block and the second positioning support block respectively abut against the sides of the optical detection component for positioning. The top surfaces of the first positioning support block and the second positioning support block respectively abut against the lower part of the protruding edges supporting the sides of the optical detection component. The upper side of the mounting base is provided with a clearance notch, which allows a tool to drill holes in the side of the optical detection component. The clamping mechanism includes a first clamping component and a second clamping component disposed on the base plate on both sides of the mounting seat. The first clamping component includes a first pressure rod and a first cylinder that drives the first pressure rod to clamp one side of the protruding edge of the optical detection element.

The positioning mechanism uses a first positioning support block and a second positioning support block to abut against the optical inspection component from both sides, and combined with the support structure below the convex edge, effectively constrains the six degrees of freedom of the workpiece, ensuring stability during the drilling process and avoiding machining errors caused by inaccurate positioning. The clearance notch on the mounting base provides an unobstructed machining path for the tool, reducing the risk of interference and improving machining efficiency. The clamping mechanism uses a first pressure rod and a second pressure rod driven by a cylinder, which can quickly and evenly clamp the two convex edges of the optical inspection component, avoiding the cumbersome operation and uneven clamping force problems caused by traditional bolt locking methods, while also reducing the risk of workpiece deformation. The overall structure is compact, the clamping is stable and reliable, suitable for mass production, and significantly improves the machining accuracy and production efficiency of side drilling of optical inspection components.

[0032] The following is for reference. Figures 1-3 A side drilling fixture for an optical inspection component is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0033] like Figure 1 As shown, the side drilling fixture for the optical inspection component 140 mainly consists of three parts: a base plate 100, a positioning mechanism, and a clamping mechanism. A mounting base 110 is provided on the base plate 100 as the main support structure. A first positioning support block 120 and a second positioning support block 130 are respectively provided on the left and right sides of the top surface of the mounting base 110. The sides of these two positioning support blocks are in close contact with the sides of the optical inspection component 140 to achieve precise positioning. Simultaneously, their top surfaces support the undersides of the protruding edges 150 on both sides of the optical inspection component 140, forming multi-directional positioning constraints. Furthermore, the top surface of the mounting base 110 is also provided with positioning posts 280 for abutting the optical inspection component 140. The positioning posts 280 serve to supplement positioning and fixation, further ensuring the positioning accuracy and processing stability of the optical inspection component 140. In addition, a square clearance notch 160 is machined on the upper side of the mounting base 110. This notch provides an unobstructed path for the drilling tool, ensuring that no interference occurs during processing. To further expand the operating space for the cutting tools, the base plate 100 is also provided with a larger square supplementary notch 250 on the side of the avoidance notch 160. The two notches work together to provide ample operating space for drill bits of different sizes.

[0034] In the specific implementation of positioning mechanisms, such as Figure 2As shown, the top surface of the mounting base 110 is provided with a first mounting port 230 and a second mounting port 240 on both sides, respectively. These two mounting ports are used to install the first positioning support block 120 and the second positioning support block 130. This adjustable design allows the fixture to adapt to the positioning requirements of optical inspection components 140 of different sizes. Figure 1 and Figure 3 As shown, the clamping mechanism includes a first clamping assembly 170 and a second clamping assembly 180 symmetrically arranged on both sides of the mounting base 110, each clamping assembly being driven by a cylinder. The first clamping assembly 170 includes a first pressure rod 190 and a first cylinder 200, and the second clamping assembly 180 includes a second pressure rod 210 and a second cylinder 220. Both sets of cylinders are fixed to the bottom surface of the base plate 100, making the upper structure more compact. The middle portions of the first pressure rod 190 and the second pressure rod 210 are rotatably connected to the first support base 260 and the second support base 270, respectively. This design optimizes the swing trajectory of the pressure rods, making the clamping force distribution more uniform.

[0035] The overall working process of this fixture is as follows: The optical inspection component 140 is placed on the mounting base 110, ensuring that its two sides are in close contact with the first positioning support block 120 and the second positioning support block 130, while the two side protrusions 150 are stably supported by the support blocks. The first cylinder 200 and the second cylinder 220 are activated, driving the first pressure rod 190 and the second pressure rod 210 to swing around the support base, evenly pressing the protrusions 150 on both sides of the optical inspection component 140. The drilling tool performs precise drilling on the side of the optical inspection component 140 through the avoidance notch 160 and the supplementary notch 250. After machining, the cylinder releases the pressure rod, allowing for quick removal of the workpiece. This fixture, through the synergistic effect of multi-directional positioning constraints and cylinder-driven clamping, achieves high-precision and high-efficiency clamping and drilling of the optical inspection component 140, effectively solving the problems of insufficient positioning accuracy and low clamping efficiency of traditional fixtures, significantly improving machining quality and production efficiency, and is particularly suitable for mass production environments.
