Abstract
Description
Technical Field
[0001] This utility model relates to the field of tungsten wire mold testing technology, specifically to a testing device for tungsten wire molds. Background Technology
[0002] The working principle of a wire drawing die is that the metal wire passes through the die and gradually thins to achieve the required size.
[0003] The core of a silk die is generally made of natural diamond or synthetic diamond (such as GE, PCD, synthetic materials, etc.);
[0004] Tungsten wire molds are used to gradually refine tungsten wires from thick to thin to achieve the required dimensions. After production and forming, the tungsten wire molds undergo optical image inspection to detect defects. These defects are displayed or marked on a monitor or automatic indicator to ensure the quality of the molds before they leave the factory. Optical image inspection of tungsten wire molds requires a detection device, but existing devices cannot clamp and fix tungsten wire molds of different sizes during inspection, affecting the accuracy of the inspection. Furthermore, insufficient light intensity often occurs during optical image inspection of tungsten wire molds, leading to inaccurate results. Summary of the Invention

One end of the movable rod is connected to the supplementary lighting plate through damping rotation. A fixing rod is fixedly installed on the side surface of the mounting frame, and the fixing rod is threadedly connected to the second fixing bolt.
[0008] A further option is that the three mounting blocks are arranged in a triangular pattern on the fixing block.
[0009] A further embodiment is that two electric telescopic rods are symmetrically fixedly connected to the left and right sides of the top of the detection base, and the movable ends of the two electric telescopic rods are fixedly connected to the same crossbeam.

Detailed Implementation
[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] like Figure 1-5 As shown, one embodiment of this utility model discloses a detection device for tungsten wire molds, including a detection base 1, a detection groove 10 is provided in the middle of the detection base 1, and a fixing mechanism for fixing the tungsten wire mold is provided in the detection groove 10.
[0024] The fixing mechanism includes a fixing block 30 and three screws 31. The fixing block 30 is cylindrical. Three arc-shaped mounting blocks 32 are fixedly installed on the top of the fixing block 30. Each of the three mounting blocks 32 has a through hole that passes through the mounting block 32. The through hole has an internal thread. One end of the screw 31 passes through the through hole and is fixedly connected to an arc-shaped clamping block 33. The other end of the screw 31 is fixedly connected to a handle 34.
[0025] This embodiment, through the above-described configuration, allows the tungsten wire mold to be placed at the center of the top of the fixing block, ensuring that the vertical axis of the mold is aligned with the vertical axis of the fixing block. Then, the three handles are rotated one by one, moving the three clamping blocks toward the tungsten wire mold until they contact the outer surface of the mold. This allows for the clamping and fixing of tungsten wire molds of different sizes using the fixing mechanism.
[0026] In this embodiment, a camera device 2 is provided above the detection slot 10; the camera device 2 can be a CCD camera or other equipment capable of capturing images of the tungsten filament mold. In this embodiment, a CCD camera is used. Two electric telescopic rods 50 are symmetrically fixedly connected to the left and right sides of the top of the detection base 1, and the movable ends of the two electric telescopic rods 50 are fixedly connected to the same crossbeam 51; a drive motor 52 is fixedly provided at the bottom of the crossbeam 51, and the power output shaft of the drive motor 52 is fixedly connected to a lead screw 53. A moving block 54 is threadedly connected to the lead screw 53, and the camera device 2 is fixed at the bottom of the moving block 54.
[0027] This embodiment, through the above-described configuration, enables the simultaneous up-and-down movement of a crossbeam by activating two electrically operated telescopic rods. This movement, via the vertical movement of the rods' movable ends, moves the CCD camera fixed below the crossbeam vertically. Simultaneously, a drive motor rotates a lead screw, causing a horizontally moving block fitted onto the lead screw. This, in turn, moves the CCD camera at the bottom of the moving block horizontally, allowing for adjustment of the CCD camera's position both vertically and horizontally. This facilitates accurate focusing of the CCD camera when performing optical image inspection of the clamped tungsten filament mold plate below, improving inspection accuracy.
[0028] The top of the detection base 1 is equipped with a supplementary lighting mechanism for optical image detection of tungsten filament molds. The supplementary lighting mechanism includes a mounting base 40 and a sliding ring 41. The mounting base is fixedly installed on the top of the detection base 1. The sliding ring 41 is located on top of the mounting base 40. A groove 42 is provided at the bottom of the sliding ring 41, allowing it to be movably connected to the mounting base 40 via the groove 42. Several equidistant mounting slots 43 are provided at the top of the sliding ring 41. One end of a first fixing bolt 44 penetrates the side surface of the sliding ring 41 and extends into the interior of the mounting slot 43. A mounting bracket 45 is installed inside the mounting slot 43. A movable groove 46 is provided on the side surface of the mounting bracket 45, movably connected to a movable rod 47. One end of the movable rod 47 is connected to a supplementary lighting plate 48 via damped rotation. A fixing rod 49 is fixedly installed on the side surface of the mounting bracket 45, and the fixing rod 49 is threadedly connected to a second fixing bolt 490. The bottom of the second fixing bolt 490 contacts the top of the movable rod 47.
[0029] In this embodiment, through the above settings, when there is insufficient light during the optical image detection of the tungsten wire mold, the light supplement mechanism of this embodiment can supplement the light, which can avoid affecting the detection accuracy due to insufficient light conditions. Specifically, the mounting bracket can be installed inside the mounting groove and fixed with the first fixing bolt. Then, the position of the movable rod is adjusted to adjust the position of the light supplement plate, and then the angles of the light supplement plate and the light supplement lamp can be freely adjusted. The light supplement lamp irradiates to supplement the light in an environment with insufficient light conditions, avoiding affecting the accuracy of the optical image detection of the tungsten wire mold due to insufficient light conditions and improving the detection accuracy.
[0030] In this embodiment, the three mounting blocks 32 are distributed in a "pin" shape on the fixed block 30.
[0031] Through the above settings in this embodiment, it can be realized that the clamping blocks distributed in a "pin" shape can stably clamp and fix the tungsten wire mold.
[0032] In this embodiment, the upper part of the mounting bracket 45 is inclined.
[0033] Through the above settings in this embodiment, it can be realized that better light supplement can be provided for the top of the tungsten wire mold.
[0034] In this embodiment, two symmetrically arranged support blocks 60 are arranged inside the detection groove 10. The fixed block 30 is arranged between the two support blocks 60. One side of the fixed block 30 is fixedly connected to the power output shaft of the rotation motor 62 through a rotating shaft 61, and the rotation motor 62 is fixedly arranged on the top of one of the support blocks 60.
[0035] Through the above settings in this embodiment, it can be realized that by starting the rotation motor, the power output shaft of the rotation motor rotates to drive the rotating shaft and the fixed block to rotate a certain angle between the two support blocks, and then带动 the tungsten wire mold to rotate a certain angle. Then, the surface of different positions and angles of the tungsten wire mold can be optically imaged and detected by the CCD camera.
[0036] Finally, it should be noted that the above only describes the specific embodiments of the present invention in detail. However, the present invention is not limited to the above-described specific embodiments. Equivalent modifications and substitutions made by those skilled in the art to the present invention are also within the scope of the present invention. Therefore, equivalent transformations and modifications made without departing from the spirit and scope of the present invention are all covered by the present invention.
