Description

Technical Field

[0001] This invention relates to the field of camera photography, and more particularly to a camera lighting device and a Brinell hardness tester standard machine using the camera lighting device. Background Technology

[0002] Brinell hardness testers are mainly used for hardness determination of materials such as cast iron, steel, non-ferrous metals, and soft alloys. The Brinell hardness test produces the largest indentation among all hardness tests, reflecting the comprehensive properties of the material and is unaffected by microscopic segregation or compositional inhomogeneity in the sample structure. Therefore, it is a highly accurate hardness testing method. Brinell hardness testers are typically calibrated using standard hardness blocks. A Brinell hardness tester that can be calibrated using standard hardness blocks is called a Brinell hardness tester standard machine or a standard Brinell hardness tester.

[0003] Existing Brinell hardness tester standard machines, such as the "Brinnell Hardness Tester Standard Machine" disclosed in Chinese Patent CN209727675U, include a frame, on which a slide rail seat is installed that can move up and down driven by a loading mechanism. The slide rail seat is provided with a straight guide rail that extends horizontally. A mounting seat is mounted on the straight guide rail. A Brinell indenter and a shooting device are arranged side by side on the mounting seat. A mounting seat drive mechanism is provided between the slide rail seat and the mounting seat to drive the mounting seat to move back and forth linearly. The shooting device is a vertically arranged industrial camera.

[0004] In use, the mounting base moves back and forth along a straight guide rail under the drive of the mounting base drive mechanism. When pressure needs to be applied to the workpiece to be tested or the standard hardness block to be pressed, the mounting base moves the Brinell indenter above the workpiece, and the loading mechanism moves the Brinell indenter downward to apply pressure to the workpiece. After pressure is applied, the loading mechanism moves the Brinell indenter upward, and the mounting base drive mechanism moves the mounting base, carrying the imaging device, above the workpiece. The imaging device then photographs the workpiece to obtain indentation information. The existing Brinell hardness tester standard machine has the problem that the operating environment lacks appropriate supplementary lighting equipment, making it difficult for the industrial camera to capture ideal patterns due to lighting conditions. Summary of the Invention

[0005] The purpose of this invention is to provide a camera illumination device for providing supplemental lighting to a camera; another purpose of this invention is to provide a Brinell hardness tester standard machine using the camera illumination device.

[0006] To solve the above-mentioned technical problems, the technical solution of the camera supplementary lighting device in this invention is as follows: A camera lighting device includes an outer cylinder and an inner cylinder that is guided and moved to the lower end of the outer cylinder. The camera lighting device also includes an inner cylinder driving mechanism for driving the inner cylinder to move up and down. An angle adjustment component is provided at the lower end of the inner cylinder, and the angle adjustment component forms a conical camera penetration channel with a diameter that gradually decreases from bottom to top. The camera lighting device also includes a taper adjustment mechanism for adjusting the taper of the conical camera penetration channel. At least two rings of lighting lamps are arranged at intervals along the vertical direction on the channel wall of the conical camera penetration channel, and each lighting lamp group includes at least two lighting lamps arranged at intervals along the circumferential direction.

[0007] Furthermore, the outer cylinder has an outer cylinder guide groove extending in the vertical direction, and the inner cylinder has a guide rod that extends radially from the outer side of the corresponding outer cylinder guide groove. The inner cylinder drive mechanism includes a first electric push rod that is connected to the guide rod in a transmission manner.

[0008] Furthermore, the angle adjustment component is a hollow annular airbag structure with a triangular cross-sectional shape. The lower sidewall of the angle adjustment component forms the through-channel of the cone-shaped camera. The taper adjustment mechanism includes an air pipe communicating with the inner hole of the angle adjustment component and an air pump for drawing air into and releasing air into the air pipe.

[0009] Furthermore, the angle adjustment component includes multiple adjustment plates arranged at intervals along the circumference. The conical camera through-channel is surrounded by the adjustment plates. The lower end of each adjustment plate is hinged to the lower end of the inner cylinder. The fill lights of each fill light group are evenly distributed on the inner wall of the corresponding adjustment plate. The taper adjustment mechanism includes a second electric push rod corresponding to the adjustment plate. One end of the second electric push rod is hinged to the inner cylinder, and the other end is hinged to the outer side of the upper end of the corresponding adjustment plate.

[0010] Furthermore, each fill light unit has its fill light hinged to the inner wall of the adjustment plate. The hinge axis of each fill light is perpendicular to the vertical direction, allowing the fill light to swing up and down. The inner cylinder is also equipped with a fill light angle adjustment mechanism that drives the corresponding fill light to swing up and down.

[0011] Furthermore, each fill light has an upper wire lug at its upper end and a lower wire lug at its lower end. The fill light angle adjustment mechanism includes a motor-driven winding drum corresponding to each fill light group. A first elastic pull rope is threaded through the upper wire lug of each fill light in each fill light group, and a second elastic pull rope is threaded through the lower wire lug of each fill light in each fill light group. The two ends of the first elastic pull rope are wound and connected to one end of the corresponding winding drum, and the two ends of the second elastic pull rope are wound and connected to the other end of the corresponding winding drum. The winding direction of the first elastic pull rope and the winding drum is opposite to the winding direction of the second elastic pull rope and the winding drum.

[0012] The technical solution of the Brinell hardness tester standard machine in this invention is as follows: The Brinell hardness tester standard machine includes a frame, on which a slide rail seat capable of vertical movement driven by a loading mechanism is mounted. A straight guide rail extending horizontally is mounted on the slide rail seat, and a mounting seat is mounted on the straight guide rail. A Brinell indenter and a camera are arranged side-by-side on the mounting seat. A mounting seat drive mechanism is provided between the slide rail seat and the mounting seat to drive the mounting seat to reciprocate linearly. The Brinell hardness tester standard machine also includes a camera supplementary lighting device, comprising an outer cylinder and an inner cylinder guided and moved at the lower end of the outer cylinder. The camera supplementary lighting device also includes an inner cylinder drive mechanism for driving the inner cylinder to move vertically. An angle adjustment component is provided at the lower end of the inner cylinder, forming a tapered camera penetration channel with a gradually decreasing diameter from bottom to top. The camera supplementary lighting device also includes a taper adjustment mechanism for adjusting the taper of the tapered camera penetration channel. At least two rings of supplementary lighting lamps are arranged at intervals in the vertical direction on the channel wall of the tapered camera penetration channel, and each supplementary lighting lamp group includes at least two supplementary lighting lamps arranged at intervals in the circumferential direction.

[0013] Furthermore, the angle adjustment component is a hollow annular airbag structure with a triangular cross-sectional shape. The lower sidewall of the angle adjustment component forms the through-channel of the cone-shaped camera. The taper adjustment mechanism includes an air pipe communicating with the inner hole of the angle adjustment component and an air pump for drawing air into and releasing air into the air pipe.

[0014] Furthermore, the angle adjustment component includes multiple adjustment plates arranged at intervals along the circumference. The conical camera through-channel is surrounded by the adjustment plates. The lower end of each adjustment plate is hinged to the lower end of the inner cylinder. The fill lights of each fill light group are evenly distributed on the inner wall of the corresponding adjustment plate. The taper adjustment mechanism includes a second electric push rod corresponding to the adjustment plate. One end of the second electric push rod is hinged to the inner cylinder, and the other end is hinged to the outer side of the upper end of the corresponding adjustment plate.

[0015] Furthermore, each fill light in each fill light group is hinged to the inner wall of the adjustment plate. The hinge axis of each fill light is perpendicular to the vertical direction, allowing the fill light to swing up and down. The inner cylinder is also equipped with a fill light angle adjustment mechanism that drives the corresponding fill light to swing up and down. Each fill light has an upper wire lug at its upper end and a lower wire lug at its lower end. The fill light angle adjustment mechanism includes a motor-driven rope drum corresponding to each fill light group. A first elastic pull rope is threaded through the upper wire lug of each fill light in each fill light group, and a second elastic pull rope is threaded through the lower wire lug of each fill light in each fill light group. The two ends of the first elastic pull rope are wound and connected to one end of the corresponding rope drum, and the two ends of the second elastic pull rope are wound and connected to the other end of the corresponding rope drum. The winding direction of the first elastic pull rope and the rope drum is opposite to the winding direction of the second elastic pull rope and the rope drum.

[0016] The beneficial effects of the present invention are as follows: When the camera supplementary lighting device of the present invention is in use, the inner cylinder is fitted around the camera, and the camera passes through the conical camera through-channel. The supplementary lights on the channel wall of the conical camera through-channel are used to supplement the camera. The axial movement of the inner cylinder relative to the outer cylinder can adjust the position of the supplementary lights relative to the camera lens. The conical channel wall structure of the conical camera through-channel itself is conducive to the supplementary lights facing the camera shooting direction. The taper adjustment mechanism can adjust the supplementary lighting direction of each supplementary light by adjusting the taper of the conical camera through-channel, so as to find the optimal supplementary lighting angle.

[0017] Furthermore, the taper adjustment mechanism is equivalent to the first step of adjusting the orientation of the fill light. By rotating the winding drum, when the drum rotates clockwise, one elastic cord retracts the rope while the other elastic cord releases the rope, allowing the fill light to swing in one direction. When the drum rotates counterclockwise, one elastic cord releases the rope while the other elastic cord retracts the rope, allowing the fill light to swing in the other direction. This achieves the second step of adjusting the fill light's direction, further ensuring the fill light's effect on the camera. The reason for using elastic cords is to ensure that the cords do not interfere with the angle adjustment of the adjustment plate. Attached Figure Description

[0019] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0020] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0021] Example 1 of the Brinell hardness tester standard machine in this invention is as follows: Figures 1-4 As shown: The device includes a frame, on which a slide rail base capable of vertical movement driven by a loading mechanism is mounted. The slide rail base has a straight guide rail extending horizontally. A mounting base 1 is mounted on the straight guide rail, and a Brinell indenter and a camera 2 are arranged side-by-side on the mounting base 1. A mounting base drive mechanism is provided between the slide rail base and the mounting base to drive the mounting base to reciprocate linearly. All of the above are prior art and will not be described in detail here.

[0022] The Brinell hardness tester standard machine also includes a camera supplementary lighting device, which includes an outer cylinder 4 whose upper end is fixedly connected to the mounting base, an inner cylinder 6 that is guided and moved at the lower end of the inner hole of the outer cylinder, and an inner cylinder drive mechanism for driving the inner cylinder to move up and down.

[0023] In this embodiment: the outer cylinder 4 is provided with an outer cylinder guide groove 5 extending in the vertical direction. There are two outer cylinder guide grooves 5, which are symmetrically arranged. The inner cylinder is fixed with a guide rod 7 that passes through the outer side of the corresponding outer cylinder guide groove in the radial direction of the inner cylinder. The inner cylinder drive mechanism includes a first electric push rod 3 that is connected to the guide rod for transmission. The two first electric push rods 3 are arranged vertically, and the upper end of the first electric push rod 3 is connected to the mounting base.

[0024] An angle adjustment component is provided at the lower end of the inner cylinder 6. The angle adjustment component forms a cone-shaped camera through-channel with a diameter that gradually decreases from bottom to top. The camera lighting device also includes a taper adjustment mechanism for adjusting the taper of the cone-shaped camera through-channel. Three rings of fill light groups are arranged at intervals in the vertical direction on the channel wall of the cone-shaped camera through-channel. Each fill light group includes multiple fill light 10 arranged at intervals in the circumferential direction.

[0025] In this embodiment, the angle adjustment component includes multiple circumferentially spaced adjustment plates 8. The conical camera through-channel is formed by these adjustment plates 8. The lower end of each adjustment plate 8 is hinged to the lower end of the inner cylinder. The hinge axis of the adjustment plate is perpendicular to the vertical direction. The fill lights of each fill light group are evenly distributed on the inner wall of the corresponding adjustment plate. The taper adjustment mechanism includes a second electric push rod 9 corresponding to the adjustment plate. One end of the second electric push rod 9 is hinged to the inner cylinder, and the other end is hinged to the outer upper side of the corresponding adjustment plate. Through the linear movement of the second electric push rod 9, the corresponding adjustment plate 8 can be driven to rotate around its hinge axis, changing the angle between the adjustment plate and the inner cylinder, thereby changing the normal direction of the fill light, i.e., the fill light direction.

[0026] In this embodiment, the fill lights of each fill light group are hinged to the inner wall of the adjustment plate. The hinge axis of each fill light is perpendicular to the vertical direction, so that the fill light can swing up and down. The inner cylinder is also provided with a fill light angle adjustment mechanism to drive the corresponding fill light to swing up and down.

[0027] Each fill light has an upper wire lug 17 at its upper end and a lower wire lug 18 at its lower end. The fill light angle adjustment mechanism includes a rope drum 14 driven by a motor 15, which is provided corresponding to each fill light group. A first elastic pull rope 11 is threaded through the upper wire lug of each fill light in each fill light group, and a second elastic pull rope 12 is threaded through the lower wire lug of each fill light in each fill light group. The two ends of the first elastic pull rope are wound and connected to one end of the corresponding rope drum, and the two ends of the second elastic pull rope 12 are wound and connected to the other end of the corresponding rope drum. The winding direction of the first elastic pull rope and the rope drum is opposite to the winding direction of the second elastic pull rope and the rope drum.

[0028] In this embodiment, there are three rings of supplementary lights from top to bottom, therefore there are also three rope drums. The rope drums and motor are mounted on the inner wall of the inner drum. The inner wall of the inner drum is also provided with a reversing pulley 16 for changing the direction of the corresponding elastic pull rope, and a drum wall threading lug 13 for changing and positioning the corresponding elastic pull rope. After the first elastic pull rope passes through the upper threading lug 17 corresponding to one ring of supplementary lights, one end passes through the corresponding drum wall threading lug and is then wound around the rope drum, while the other end passes through the corresponding drum wall threading lug 13 and is then wound around the rope drum. The drum wall threading lug has a ring structure, which can realize the limiting and reversing of the elastic pull rope. Providing threading lugs or reversing pulleys for reversing the elastic pull rope where it needs to be reversed is a conventional technical means in the prior art and will not be described in detail here.

[0029] The second elastic pull cord passes through the lower cable lug 18 corresponding to the fill light, one end goes around the reversing pulley 16, then through the corresponding cable lug on the drum wall, and then around the rope drum. The other end goes around the reversing pulley, then through the corresponding cable lug on the drum wall, and then around the rope drum. Rotating the rope drum in one direction allows one elastic pull cord to be wound up while the other elastic pull cord is unwound; rotating the rope drum in the other direction allows one elastic pull cord to be unwound while the other elastic pull cord is wound up.

[0030] In use, the first electric push rod moves the inner cylinder up and down, thereby changing the vertical position of each fill light. The second electric push rod changes the tilt angle of the adjustment plate. The change in the tilt angle of the adjustment plate changes the taper of the cone camera's through-channel, thereby changing the orientation of each fill light. The elasticity of the first and second elastic pull ropes can adapt to the angle change of the adjustment plate. The movement of the adjustment plate is a coarse adjustment in terms of the fill light's fill light direction.

[0031] Subsequently, the motor drives the corresponding rope drum to rotate, which can adjust the tilt angle of the supplementary light relative to the adjustment plate, essentially fine-tuning the direction of the supplementary light's illumination. Figure 4 For example, when the first elastic cord is retracted and the second elastic cord is released, the fill light can swing upwards; when the first elastic cord is released and the second elastic cord is retracted, the fill light can swing downwards, thereby adjusting to the best fill light effect for the camera, ensuring that the camera captures the indentation clearly without shadows.

[0032] Example 2 of Brinell hardness tester standard machine Figure 5 As shown: In Embodiment 2, unlike Embodiment 1, the supplementary light 10 does not undergo fine-tuning of its illumination direction. The angle adjustment component 19 is a hollow annular airbag structure with a triangular cross-sectional shape. The lower sidewall of the angle adjustment component forms the through-channel of the cone-shaped camera. The taper adjustment mechanism includes an air pipe communicating with the inner hole of the angle adjustment component and an air pump for pumping air into and out of the air pipe 20. By inflating and deflating the inner cavity of the angle adjustment component with the air pump, the degree of inflation of the angle adjustment component is changed, thereby changing the tilt angle of the lower sidewall of the angle adjustment component relative to the horizontal direction, and thus changing the illumination direction of the supplementary light.

[0033] Implementation of camera lighting devices, for example Figures 1-5 As shown: The specific structure of the camera lighting device is the same as that of the camera lighting devices described in the above embodiments of the Brinell hardness tester standard machine, and will not be described in detail here.
