Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of visual inspection devices, and in particular relates to a visual inspection device for surface defects of shaft components. Background Technology
[0002] Currently, all spindles undergo surface defect inspection after production. Initially, this was done by visually inspecting under bright light, often revealing microcracks finer than a hair, requiring a high level of experience and meticulousness from the inspectors. With technological advancements, microscopes and monitors are now commonly used to magnify these microcracks, significantly reducing the complexity of the inspection process. However, this process still requires operators to hold the spindle and move it axially and circumferentially. Hand tremors often necessitate adjusting the microscope or spindle height for focusing, ensuring clear visualization on the monitor. Furthermore, this manual inspection method increases worker fatigue and workload over extended periods, negatively impacting efficiency and accuracy. Therefore, we propose a visual inspection device for spindle surface defects to address these issues. Utility Model Content
[0003] In view of this, in order to solve the problem that the traditional manual component inspection method is affected by hand tremors, which causes frequent adjustments to focus during the inspection process, and the long-term operation increases the labor intensity and fatigue of the workers, thus greatly affecting the inspection efficiency and accuracy, this utility model provides a visual inspection device for surface defects of shaft components.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for surface defects of shaft components, comprising a worktable;
[0005] It also includes a monitor and a microscope, both of which are fixedly connected to one side of the top of the worktable, and are used for magnified display and inspection of shaft components, respectively;
[0006] It also includes a sliding base, which is slidably connected to the top of the worktable;
[0007] It also includes a nut block, which is slidably connected to the top of the sliding seat;
[0008] It also includes an adjustment component, located on top of the sliding seat, for sliding adjustment of the nut block;
[0009] It also includes a shaft end support block, which is fixedly connected to the top of the nut block. A positioning hole is provided on one side of the shaft end support block for positioning one end of the shaft.
[0010] Furthermore, the adjustment assembly includes two fixed blocks and an adjustment screw. The two fixed blocks are symmetrically fixedly connected to the top two sides of the sliding seat, and the nut block is located between the two fixed blocks. The adjustment screw is rotatably connected between the two fixed blocks, and the nut block is threaded onto the threaded section of the adjustment screw. One end of the adjustment screw extends outward and is fixedly connected to an adjustment handwheel.
[0011] Furthermore, the top of the shaft end support block has two symmetrical screw holes, and the top of the nut block has two symmetrical threaded holes that correspond to the screw holes. The shaft end support block and the nut block are connected by two fixing screws.
[0012] Furthermore, a support block is fixedly connected to the side of the sliding seat away from the display. A locking screw is threaded through the top of the support block. The bottom end of the locking screw extends downward and is rotatably connected to an abutment plate. The top end of the locking screw extends upward and is integrally formed with a knob.
[0013] Furthermore, an anti-slip rubber pad is fixedly provided at the bottom of the contact plate.
[0014] Furthermore, four limiting blocks are symmetrically positioned and engaged on the top of the workbench, and the four limiting blocks are respectively located at both ends of the two first slide rails, for limiting the contact of the sliding seat.
[0015] The embodiments of this utility model have the following beneficial effects:
[0016] This invention features a sliding seat on the worktable and a shaft end support block for positioning the shaft.

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] Example 1: Please refer to Figures 1-3As shown, this embodiment provides a visual inspection device for surface defects of shaft components, including a worktable 1. A display 3 and a microscope 6 are fixedly connected to one side of the top of the worktable 1, respectively for magnified display and inspection of the shaft components. Two first slide rails 2 are symmetrically fixedly connected to the top of the worktable 1, and a sliding seat 5 is slidably connected to the top of the worktable 1 via the two first slide rails 2. Two second slide rails 12 are symmetrically fixedly connected to the top of the sliding seat 5, and a nut block 8 is slidably connected to the top of the sliding seat 5 via the two second slide rails 12. A shaft end support block 11 is fixedly connected to the top of the nut block 8, and a positioning hole 111 is provided on one side of the shaft end support block 11 for positioning one end of the shaft component. In use, one end of the shaft component is first inserted into the positioning hole 111 and positioned and inserted by the shaft end support block 11. Then, the height of the microscope 6 is adjusted and fixed. At this time, by moving the sliding seat 5 on the first slide rails 2, the shaft component can be moved and inspected under the microscope 6, and the inspected image is magnified by the display 3, thus facilitating the observation of surface defects of the shaft component. This inspection method effectively avoids the shaking that easily occurs when manually handling shafts, as well as the need for constant height and focus adjustments that could affect the normal inspection of the shafts. Furthermore, when it is necessary to observe the circumferential surface of the shaft, it can be done simply by manually rotating the shaft, making the inspection operation very convenient.
[0026] In one aspect of this embodiment, four limiting blocks 4 are symmetrically positioned and engaged on the top of the worktable 1 in pairs. These four limiting blocks 4 are located at the two ends of the two first slide rails 2, serving to limit the contact of the sliding seat 5. The limiting blocks 4 limit the movement distance of the sliding seat 5 at both ends, preventing excessive sliding and thus preventing the sliding seat 5 from disengaging from the first slide rail 2. Furthermore, the limiting blocks 4 are engaged with locking holes integrally formed on them, facilitating disassembly. Alternatively, only two limiting blocks 4 on the same side can be engaged. After disassembling the limiting blocks 4, the entire sliding seat 5 can be easily slid out and removed, facilitating replacement and maintenance.
[0027] This invention can be used in the field of visual inspection devices for surface defects of shafts, and can also be applied to other fields.
[0028] Example 2: This example is a further improvement on the previous example: as follows Figures 1-3As shown, two fixed blocks 7 are symmetrically fixedly connected to the top of the sliding seat 5, and a nut block 8 is located between the two fixed blocks 7. A single adjusting screw 10 is rotatably connected between the two fixed blocks 7, and the nut block 8 is threaded onto the threaded section of the adjusting screw 10. One end of the adjusting screw 10 extends outward and is fixedly connected to an adjusting handwheel 13. The adjusting handwheel 13 facilitates pushing or pulling the sliding seat 5, allowing it to slide back and forth on the worktable 1. When fine observation of a shaft is required, the traditional method of manually pushing the sliding seat 5 to move and adjust the shaft under the microscope 6 is not easy to accurately determine the display position, requiring repeated back-and-forth adjustments, which is time-consuming. In this case, after moving the approximate area of the shaft to be inspected to the microscope 6, rotating the adjusting handwheel 13 rotates the adjusting screw 10, which moves the nut block 8 within the sliding seat 5 and simultaneously moves the shaft end support block 11, thus achieving fine adjustment of the shaft and allowing it to be quickly adjusted to the precise area to be inspected, facilitating accurate display on the monitor 3.
[0029] Example 3: This example is a further improvement on the previous example: as follows Figure 3 As shown, the top of the shaft end support block 11 has two symmetrically arranged screw holes 112, and the top of the nut block 8 has two symmetrically arranged threaded holes 81 that correspond to the screw holes 112. The shaft end support block 11 and the nut block 8 are connected by two fixing screws 14. By placing the shaft end support block 11 on top of the nut block 8, aligning the screw holes 112 with the threaded holes 81, and then inserting the fixing screws 14 to connect with the threaded holes 81, the shaft end support block 11 can be fixed to the nut block 8. Conversely, by removing the fixing screws 14, the shaft end support block 11 can be disassembled to replace the positioning holes 111 of different sizes, thus adapting to the positioning and detection of shafts of different sizes and improving the practicality of the entire device.
[0030] Example 4: This example is a further improvement on the previous example: as follows Figures 1-4As shown, a support block 9 is fixedly connected to the side of the sliding seat 5 away from the display 3. A locking screw 15 is threaded through the top of the support block 9. The bottom end of the locking screw 15 extends downward and is rotatably connected to a contact plate 16. The top end of the locking screw 15 extends upward and is integrally formed with a knob 17. When the contact plate 16 is not in contact with the table surface of the worktable 1, the sliding seat 5 can be pushed back and forth normally. When precise inspection of a part of the shaft is required, or when only a certain part of the shaft in a batch needs to be inspected on its circumferential surface, the sliding seat 5 can be adjusted to the corresponding position on the worktable 1. Then, by rotating the knob 17, the locking screw 15 is rotated. At the same time, the locking screw 15 drives the contact plate 16 to move downward, and the bottom of the contact plate 16 is made to tightly contact the table surface of the worktable 1. This completes the movement limit effect of the entire sliding seat 5, making the entire inspection process more stable and facilitating better inspection operations. An anti-slip rubber pad 18 is fixedly provided on the bottom of the contact plate 16. By setting the anti-slip rubber pad 18, the contact tightness between the contact plate 16 and the worktable 1 can be improved, thereby improving the braking effect on the sliding seat 5.
[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the display 3 and the microscope 6 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
