Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for detecting the quality of the inner wall of a hole, and in particular to a device for detecting the quality of the inner wall of a hole. Background Technology

[0002] After machining deep holes in shaft-type parts, it is necessary to inspect the machining quality of the inner wall of the hole. The existing method for inspecting the inner wall of the hole involves using a smooth-walled plug with an outer diameter that matches the inner diameter of the hole to be tested. If the plug can be easily inserted, it indicates that the inner wall quality of the hole is relatively good; if it cannot be easily inserted, it indicates that the inner wall quality of the hole is poor. The above inspection method has poor accuracy and is time-consuming. It also requires machining plug structures adapted to different hole diameters, which increases production costs. Therefore, it is particularly important to design a hole inner wall quality inspection device to solve the above technical problems. Utility Model Content

[0003] The purpose of this invention is to solve the problems of existing methods for detecting the inner wall quality of holes in parts. These methods involve using a smooth-walled plug rod with an outer diameter matching the inner diameter of the hole to be tested. If the plug rod can be easily inserted, it indicates that the inner wall quality of the hole is relatively good; if it cannot be easily inserted, it indicates that the inner wall quality is poor. These methods are inaccurate, time-consuming, and require the fabrication of plug rod structures adapted to different hole diameters, increasing production costs. Therefore, this invention proposes a hole inner wall quality detection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hole inner wall quality inspection device, comprising a working seat, a receiving groove provided in the working seat, a motor installed in the receiving groove, a rotor rotatably connected to the motor, a test platform fixedly connected to the rotor, limit seats evenly distributed on the test platform, a part to be tested installed on the limit seats, a stand installed on the left side of the test platform, an electric cylinder installed on the stand directly above the part to be tested, a sliding rod slidably connected in the electric cylinder, the sliding rods being symmetrically distributed in the electric cylinder, a motor installed at the end of the sliding rod away from the electric cylinder via a connecting seat, a rotating shaft rotatably connected in the motor, and a measuring rod fixedly connected to the rotating shaft.

[0005] Preferably, a convex ball is fixedly connected to the top of the measuring rod, a rectangular block is fixedly connected to the measuring rod, a camera module is slidably connected in the rectangular block, and a central processing unit is also installed at the bottom of the stand. The central processing unit and the camera module are connected by a cable.

[0006] Preferably, the rectangular block has a cavity, the camera module is slidably disposed in the cavity, a sliding groove is also installed in the cavity, a slider is fixedly connected to the camera module, the sliding groove is provided in the cavity, and the slider is slidably disposed in the sliding groove.

[0007] Preferably, the rectangular block has mounting holes evenly distributed throughout, and the slider is connected to the rectangular block by bolts, the bolts being adapted to the mounting holes.

[0008] Preferably, a display screen is also installed on the support frame, and the display screen is connected to the central processing unit via a data cable.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] 1. In this utility model, during use, a test bench structure is installed on the workbench, and a limiting seat is set on the test bench. The part to be tested is placed on the limiting seat, and then a test component is set on the stand directly above the part to be tested. An electric cylinder drives a sliding rod to move the motor and the test rod structure up and down above the hole. The camera module on the test rod collects data, which is then transmitted to the central processing unit via cable. After data analysis and conversion by the central processing unit, the data is finally transmitted to the display screen via a data cable and displayed as an image. The operator can directly observe the display screen. Compared with the conventional method of manually making plugs by the operator, this method is much more efficient. The present invention employs a method of semi-automatic testing of the parts to be tested, reducing the workload of workers. The overall structure is compact and easy for workers to install and maintain. It solves the problems of existing methods for testing the inner wall of holes, which involve using a smooth-walled plug rod with an outer diameter matching the inner diameter of the hole to be tested. If the plug rod can be easily inserted, it indicates relatively good quality of the inner wall of the hole; if it cannot be easily inserted, it indicates poor quality. These methods are inaccurate, time-consuming, and require custom plug rod structures for different hole diameters, increasing production costs.

[0011] 2. In this utility model, during use, a slider structure is fixedly connected to the camera module. The slider slides in the rectangular block. When the diameter is within the detection range, the operator manually screws in bolts to install and limit the camera module in the rectangular block. The camera module adopts a miniature camera structure to capture images of the inner wall of the hole. At the same time, the motor drives the rotating shaft to rotate the measuring rod in the hole, completing the data acquisition of one circle of the inner wall of the hole at that position. The data is then transmitted to the central processing unit via cable. After data processing by the central processing unit, the data is transmitted to the display screen via data cable. The display screen shows the condition of the hole wall in real time. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] This utility model employs a hole inner wall quality inspection device, including a working seat 1, a receiving groove 101 provided in the working seat 1, a motor 102 installed in the receiving groove 101, a rotor 103 rotatably connected to the motor 102, a test platform 104 fixedly connected to the rotor 103, limit seats 105 evenly distributed on the test platform 104, a part to be tested 106 installed on the limit seats 105, a stand 2 installed on the left side of the test platform 104, an electric cylinder 3 installed on the stand 2 directly above the part to be tested 106, a sliding rod 301 slidably connected in the electric cylinder 3, the sliding rods 301 being symmetrically distributed in the electric cylinder 3, a motor 303 installed at the end of the sliding rod 301 away from the electric cylinder 3 via a connecting seat 302, a rotating shaft 304 rotatably connected in the motor 303, the rotating shaft... A measuring rod 305 is fixedly connected to the 304. A convex ball 306 is fixedly connected to the top of the measuring rod 305. A rectangular block 4 is fixedly connected to the measuring rod 305. A camera module 401 is slidably connected in the rectangular block 4. A central processing unit 402 is also installed at the bottom of the stand 2. The central processing unit 402 and the camera module 401 are connected by a cable 403. A cavity 404 is provided in the rectangular block 4. The camera module 401 is slidably disposed in the cavity 404. A sliding groove 405 is also installed in the cavity 404. A slider 406 is fixedly connected to the camera module 401. The slider 406 is slidably disposed in the sliding groove 405. When the slider 406 slides in the sliding groove 405, it guides the camera module 401 to slide in the rectangular block 4.

[0018] When using the hole inner wall quality inspection device, the electric cylinder 3 and the measuring rod 305, along with other related inspection components, mounted on the stand 2 are positioned directly above the product to be inspected, allowing for rapid inspection of the hole inner wall quality. Then, the camera module 401 is adjusted relative to the rectangular block 4 according to the required hole diameter. A slider 406 is fixedly connected to the camera module 401, sliding within the rectangular block 4. When the diameter is within the acceptable range, the operator manually tightens bolts 501 to secure the camera module 401 within the rectangular block 4. Then, the electric cylinder 3 drives the slider 301, which in turn drives the motor 303 on the connecting seat 302 towards the hole position of the product to be inspected. The probe is moved until the protruding ball 306 at the end of the probe 305 abuts against the bottom wall of the hole. At this point, the electric cylinder 3 stops working, and the camera module 401 starts working. The camera module 401 uses a miniature camera structure to capture images of the inner wall of the hole. At the same time, the motor 303 drives the rotating shaft 304 to rotate the probe 305 in the hole, completing the data acquisition of one circle of the inner wall of the hole at this position. The data is then transmitted to the central processing unit 402 via the cable 403. After data processing by the central processing unit 402, the data is transmitted to the display screen 502 via the data cable 503. The display screen 502 displays the condition of the hole wall in real time. Then, the electric cylinder 3 starts working again, driving the probe 305 and the motor 303 to test the assembly. The device moves upwards to measure the inner wall quality of the previous section of the hole, gradually proceeding until the measuring rod 305 leaves the hole position, thus completing the inner wall quality inspection. The inspection results are directly displayed on the screen 502 for easy observation by the staff. After the measuring rod 305 resets, the motor 102 drives the rotor 103 to rotate the test platform 104, moving the next part to be tested 106 to a position below the measuring rod 305 to begin a new measurement. By installing the test platform 104 structure on the workbench 1 and setting a limit seat 105 on the test platform 104, the part to be tested 106 is placed on the limit seat 105. Then, the test assembly is set on the stand 2 directly above the part to be tested 106, and the device is powered by an electric motor. The cylinder 3 drives the slide bar 301, which in turn drives the motor 303 and the measuring rod 305 to move up and down above the hole. The camera module 401 on the measuring rod 305 collects data, which is then transmitted to the central processing unit 402 via the cable 403. After data analysis and conversion by the central processing unit 402, the data is finally transmitted to the display screen 502 via the data cable 503 and displayed as an image. The staff can directly observe the display screen 502. Compared with the conventional method of manually making a plug rod for testing, the technical solution adopted by this utility model can realize semi-automatic testing of the part 106 to be tested, which can reduce the labor intensity of the staff. The overall structure is compact and easy for the staff to install and maintain.

[0019] like Figure 1-2As shown, mounting holes 5 are evenly distributed in the rectangular block 4. The slider 406 is connected to the rectangular block 4 by bolts 501, which are adapted to the mounting holes 5. A display screen 502 is also mounted on the stand 2, and the display screen 502 is connected to the central processing unit 402 by a data cable 503.

[0020] The overall effect of Embodiment 1 is that, during use, a slider 406 structure is fixedly connected to the camera module 401. The slider 406 slides in the rectangular block 4. When the diameter is within the detection range, the operator manually screws in the bolt 501 to install and limit the camera module 401 in the rectangular block 4. The camera module 401 adopts a miniature camera structure to capture images of the inner wall of the hole. At the same time, the motor 303 drives the rotating shaft 304 to rotate the measuring rod 305 in the hole, completing the data acquisition of one circle of the inner wall of the hole at that position. Then, the data is transmitted to the central processing unit 402 via the cable 403. After the data is processed by the central processing unit 402, it is transmitted to the display screen 502 via the data cable 503. The display screen 502 displays the condition of the hole wall in real time.

[0021] Working Principle: Because the electric cylinder and measuring rod, along with other related detection components, are positioned directly above the product under test on the stand, the inspection of the inner wall quality of the hole in the product can be performed quickly. Then, the camera module is adjusted relative to the rectangular block according to the required diameter of the hole to be inspected. A slider structure is fixedly connected to the camera module, and the slider slides within the rectangular block. When the diameter is within the acceptable range, the operator manually tightens bolts to secure the camera module within the rectangular block. Then, the electric cylinder drives the sliding rod, which in turn moves the motor on the connecting seat towards the hole in the product under test until the convex ball at the end of the measuring rod abuts against the bottom wall of the hole. At this point, the electric cylinder stops working, and the camera module begins operation. The camera module uses a miniature camera. The head structure captures images of the inner wall of the hole using a camera. Simultaneously, a motor drives a rotating shaft to rotate the measuring rod within the hole, completing a full circle of data acquisition for that location. The data is then transmitted via cable to a central processing unit (CPU). After processing, the data is transmitted again via a data cable to a display screen, which shows the real-time condition of the hole wall. The electric cylinder then drives the measuring rod and motor-driven testing assembly upwards to complete the measurement of the previous section of the hole wall quality. This process continues until the measuring rod leaves the hole, completing the quality inspection of the inner wall. The inspection results are directly displayed on the screen for easy observation by staff. After the measuring rod resets, the motor drives a rotor to rotate the testing platform, moving the next part to be measured to a position below the measuring rod to begin a new measurement.
