Description

Technical Field

[0001] This utility model belongs to the technical field of defect detection devices, and more specifically, relates to a device for detecting surface defects in hardware casings. Background Technology

[0002] A magnetic particle flaw detector is a flaw detection instrument. This equipment is suitable for detecting cracks and minor defects on the surface and near the surface of various small and medium-sized hardware parts caused by casting, quenching, processing, fatigue, etc. using the wet magnetic particle method. It is the preferred model for single-piece inspection, small-batch sampling inspection, and large-volume inspection.

[0003] When using a magnetic particle flaw detector, fluorescent magnetic suspension is sprayed onto the surface of the metal casing. Then, the detector's spotlight is used to illuminate the outer surface of the metal casing. Defects and scratches on the outer surface of the metal casing will be revealed under the light. However, if foreign objects bump or knock the spotlight while the flaw detector is being carried or when it is not in use, the spotlight may be damaged, which will affect the normal use of the flaw detector. Utility Model Content

[0004] The main purpose of this utility model is to provide a device for detecting surface defects in hardware casings.

[0005] According to a first aspect of the present invention, a surface defect detection device for hardware casings is provided, comprising a flaw detector body. Two extension rods are fixedly connected to one side of the flaw detector body, and an adjustable support rod is fixedly connected to one end of each extension rod. A searchlight is fixedly connected to one side of one of the extension rods, and a protective device is provided on one side of the searchlight. The protective device includes two first L-shaped plates, one end of each of the two first L-shaped plates being symmetrically fixedly connected to the outer surface of one end of the searchlight. A round rod is slidably connected to the inner wall of each L-shaped plate. An auxiliary block is fixedly connected to one close end of each of the two round rods. A protective plate is fixedly connected to one side of each auxiliary block, and one side of the protective plate abuts against one side of the searchlight. A fixing block is fixedly connected to one close side of each of the two protective plates. A pin is fixedly connected to one side of one fixing block, and the outer surface of the pin is inserted into the inner wall of the other fixing block. A rubber block is fixedly connected to one end of the pin. An interface end is fixedly connected to one end of the flaw detector body, and fixing devices are provided on both sides of the interface end.

[0006] By setting two protective plates and pushing them to move on one side of the searchlight, the protective plates will cause the round rod to slide on the inner wall of the first L-shaped plate until the two protective plates abut against each other. At this time, the rubber block and the pin will enter the inner wall of another fixing block. One end of the rubber block is small, making it easy to insert into the inner wall of the fixing block, while the other end of the rubber block is larger, which can limit the movement between the pin and the fixing block, thereby fixing the two protective plates. The two protective plates can protect one side of the searchlight, which helps to prevent debris from directly hitting the side of the searchlight when carrying the flaw detector or when the flaw detector is not in use, thus preventing damage to the searchlight and facilitating the normal use of the flaw detector.

[0007] According to the hardware casing surface defect detection device of the first aspect embodiment of this utility model, a spring is sleeved on the outer surface of the round rod, and the two ends of the spring are respectively fixedly connected to one side of the auxiliary block and the first L-shaped plate. By setting the spring, when the two protective plates abut against each other, the spring is in a stretched state. When the searchlight needs to be used, the two protective plates are pushed in the opposite direction, so that the rubber block is disengaged from the inner wall of the fixed block. Then the spring will reset and drive the two protective plates away from each other until one side of the searchlight is not completely blocked, which facilitates the quick use of the searchlight.

[0008] According to the hardware shell surface defect detection device of the first aspect of the present invention, a circular block is fixedly connected to one end of each of the two circular rods that are far apart from each other, and the outer diameter of the circular block is larger than the outer diameter of the circular rod.

[0009] By setting a circular block, one end of the circular rod can be limited, which helps to prevent the circular rod from detaching from the inner wall of the first L-shaped plate. At the same time, when the two protective plates abut against each other, one side of the circular block abuts against one side of the first L-shaped plate, which can fix the two protective plates and help prevent the protective plates from shifting on one side of the searchlight.

[0010] According to the hardware casing surface defect detection device of the first aspect embodiment of the present invention, a slider is fixedly connected to one side of the auxiliary block, and the outer surface of the slider is slidably connected to the inner wall of the first L-shaped plate. By setting the slider, when the protective plate moves under the drive of the spring, it will drive the slider to slide synchronously on the inner wall of the first L-shaped plate, which can make the protective plate more stable during the movement.

[0011] According to the hardware casing surface defect detection device described in the first aspect of this utility model, rubber strips are adhered to the adjacent sides of the two protective plates, and one side of the two rubber strips abuts against each other. By setting two rubber strips, the abutting surfaces of the two protective plates can be auxiliaryly sealed, thereby improving the protective performance of the two protective plates against the searchlight.

[0012] According to the hardware shell surface defect detection device of the first aspect embodiment of the present utility model, the fixing device includes two second L-shaped plates. One end of each of the two second L-shaped plates is symmetrically fixedly connected to both sides of one end of the flaw detector. A threaded rod is slidably connected to the inner wall of the second L-shaped plate. A clamping plate is fixedly connected to the adjacent ends of the two threaded rods. The two clamping plates are symmetrically arranged on both sides of the interface end. A nut is threadedly connected to the outer surface of the threaded rod. The nut is arranged between the clamping plate and the second L-shaped plate.

[0013] By setting two clamping plates, when the power cord terminal is connected to the interface terminal, pushing the two clamping plates towards the interface terminal will cause the threaded rod to slide on the inner wall of the second L-shaped plate until the two clamping plates completely clamp the power cord terminal. Then, rotate the nut so that one side of the nut abuts against one side of the second L-shaped plate. The nut can limit the threaded rod and the clamping plates, and the two clamping plates provide auxiliary fixation between the power cord terminal and the interface terminal, which helps to prevent the power cord terminal from separating from the interface terminal.

[0014] According to the hardware casing surface defect detection device described in the first aspect of this utility model, a rubber plate is fixedly connected to one side of each of the two clamping plates that are close to each other. One side of the rubber plate is arc-shaped, and a stop block is fixedly connected to the other end of the threaded rod. By setting the rubber plate, one side of the clamping plate can abut against the outer surface of the terminal, thus providing a certain degree of protection for the power terminal. The stop block can block one end of the threaded rod, which helps to prevent the nut from dislodging from the threaded rod due to misoperation.

[0015] According to the hardware casing surface defect detection device of the first aspect embodiment of the present invention, a sliding rod is fixedly connected to one side of the clamping plate, and the outer surface of the sliding rod is slidably connected to the inner wall of the second L-shaped plate. By setting the sliding rod, when the clamping plate moves under the drive of the threaded rod, it will drive the sliding rod to slide synchronously on the inner wall of the second L-shaped plate, which can limit and guide the clamping plate.

[0016] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0017] In this hardware casing surface defect detection device, two protective plates are set up. When the two protective plates are pushed until one side of the two protective plates abuts, the rubber block and the pin will limit and fix the pin and the fixing block. The two protective plates can protect one side of the searchlight, which helps to prevent debris from directly hitting the searchlight side when carrying the flaw detector or when the flaw detector is idle, thereby preventing damage to the searchlight and facilitating the normal use of the flaw detector.

[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] Reference Figures 1 to 5 As shown, a surface defect detection device for hardware casings is provided, including a flaw detector body 1. Two extension rods 2 are fixedly connected to one side of the flaw detector body 1. An adjustable support rod 3 is fixedly connected to one end of each extension rod 2. A searchlight 4 is fixedly connected to one side of one of the extension rods 2. A protective device 5 is provided on one side of the searchlight 4. The protective device 5 includes two first L-shaped plates 51. One end of each first L-shaped plate 51 is symmetrically fixedly connected to the outer surface of one end of the searchlight 4. A round rod 52 is slidably connected to the inner wall of the L-shaped plate. An auxiliary block 53 is fixedly connected to the adjacent ends of the two round rods 52. A protective plate 54 is fixedly connected to one side of the auxiliary block 53. One side of the protective plate 54 abuts against one side of the searchlight 4. A fixing block 55 is fixedly connected to the adjacent sides of the two protective plates 54. A pin 56 is fixedly connected to one side of one of the fixing blocks 55.

[0031] In some embodiments of this utility model, the outer surface of the pin 56 is inserted into the inner wall of another fixing block 55, one end of the pin 56 is fixedly connected to a rubber block 57, one end of the flaw detector body 1 is fixedly connected to an interface end 6, and fixing devices 7 are provided on both sides of the interface end 6.

[0032] By setting two protective plates 54, the two protective plates 54 are pushed to move on one side of the searchlight 4. The protective plates 54 will drive the round rod 52 to slide on the inner wall of the first L-shaped plate 51 until the two protective plates 54 abut on one side. At this time, the rubber block 57 and the pin 56 will enter the inner wall of another fixing block 55. One end of the rubber block 57 is small, which makes it easy to insert into the inner wall of the fixing block 55. At the same time, the other end of the rubber block 57 is larger, which can limit the pin 56 and the fixing block 55, thereby fixing the two protective plates 54. The two protective plates 54 can protect one side of the searchlight 4, which helps to prevent debris from directly hitting the searchlight 4 side during the carrying of the flaw detector and during the process of the flaw detector being idle, thereby preventing damage to the searchlight 4 and facilitating the normal use of the flaw detector.

[0033] In some embodiments of this utility model, the adjustable support rod 3 is composed of three rotatable metal blocks, which are fixed at the connection with bolts and nuts. The three metal blocks of the adjustable support rod 3 can be rotated according to the size of the hardware shell, so that the adjustable support rod 3 can support the top of hardware shells of different sizes and adapt to metal shells of different sizes.

[0034] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a spring 58 is sleeved on the outer surface of the round rod 52. The two ends of the spring 58 are fixedly connected to one side of the auxiliary block 53 and the first L-shaped plate 51, respectively. By setting the spring 58, when the two protective plates 54 abut against each other, the spring 58 is in a stretched state. When the searchlight 4 needs to be used, the two protective plates 54 are pushed in the opposite direction, so that the rubber block 57 is separated from the inner wall of the fixed block 55. Then the spring 58 will reset and drive the two protective plates 54 away from each other until one side of the searchlight 4 is not blocked at all, which facilitates the quick use of the searchlight 4.

[0035] Two circular rods 52 are fixedly connected to circular blocks 59 at their far ends. The outer diameter of the circular blocks 59 is larger than the outer diameter of the circular rods 52. By setting the circular blocks 59, one end of the circular rods 52 can be limited, which helps to prevent the circular rods 52 from detaching from the inner wall of the first L-shaped plate 51. At the same time, when the two protective plates 54 abut against each other, one side of the circular blocks 59 abuts against one side of the first L-shaped plate 51, which can fix the two protective plates 54 and help to prevent the protective plates 54 from shifting on one side of the searchlight 4.

[0036] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a slider 510 is fixedly connected to one side of the auxiliary block 53. The outer surface of the slider 510 is slidably connected to the inner wall of the first L-shaped plate 51. By setting the slider 510, when the protective plate 54 moves under the drive of the spring 58, it will drive the slider 510 to slide synchronously on the inner wall of the first L-shaped plate 51, which can make the protective plate 54 more stable during the movement.

[0037] Rubber strips 511 are glued to the sides of the two protective plates 54 that are close to each other. The two rubber strips 511 abut against each other. By setting two rubber strips 511, the abutting surfaces of the two protective plates 54 can be sealed, which helps to improve the protective performance of the two protective plates 54 against the searchlight 4.

[0038] Reference Figure 4 and Figure 5As shown, in some embodiments of this utility model, the fixing device 7 includes two second L-shaped plates 71. One end of each of the two second L-shaped plates 71 is symmetrically fixedly connected to both sides of one end of the flaw detector. Threaded rods 72 are slidably connected to the inner walls of the second L-shaped plates 71. Clamping plates 73 are fixedly connected to the adjacent ends of the two threaded rods 72. The two clamping plates 73 are symmetrically arranged on both sides of the interface end 6. Nuts 74 are threadedly connected to the outer surfaces of the threaded rods 72. Nuts 74 are arranged between the clamping plates 73 and the second L-shaped plates 71.

[0039] By setting two clamping plates 73, when the power cord terminal is connected to the interface end 6, the two clamping plates 73 are pushed to move towards the interface end 6. The clamping plates 73 will drive the threaded rod 72 to slide on the inner wall of the second L-shaped plate 71 until the two clamping plates 73 completely clamp the power cord terminal. Then, the nut 74 is rotated so that one side of the nut 74 abuts against one side of the second L-shaped plate 71. The nut 74 can limit the threaded rod 72 and the clamping plates 73. The two clamping plates 73 provide auxiliary fixation between the power cord terminal and the interface end 6, which helps to prevent the power cord terminal from separating from the interface end 6.

[0040] Reference Figure 4 and Figure 5 As shown, in some embodiments of this utility model, a rubber plate 75 is fixedly connected to one side of each of the two clamping plates 73 that are close to each other. One side of the rubber plate 75 is arc-shaped, and a stop block 76 is fixedly connected to the other end of the threaded rod 72. By setting the rubber plate 75, one side of the clamping plate 73 can be replaced to abut against the outer surface of the terminal, which can play a certain role in protecting the power terminal. The stop block 76 can block one end of the threaded rod 72, which helps to prevent the nut 74 from disengaging from the threaded rod 72 due to misoperation. A sliding rod 77 is fixedly connected to one side of the clamping plate 73. The outer surface of the sliding rod 77 is slidably connected to the inner wall of the second L-shaped plate 71. By setting the sliding rod 77, when the clamping plate 73 moves under the drive of the threaded rod 72, it will drive the sliding rod 77 to slide synchronously on the inner wall of the second L-shaped plate 71, which can play a role in limiting and guiding the clamping plate 73.

[0041] The two protective plates 54 are pushed to move on one side of the searchlight 4. Under the limit of the slider 510, the protective plates 54 will drive the round rod 52 to slide on the inner wall of the first L-shaped plate 51 and stretch the spring 58, causing the spring 58 to deform until the rubber strips 511 on one side of the two protective plates 54 abut against each other. At this time, the rubber block 57 and the pin 56 will enter the inner wall of another fixing block 55. One end of the rubber block 57 is small, which makes it easy to insert into the inner wall of the fixing block 55. At the same time, the other end of the rubber block 57 is large, which can limit the pin 56 and the fixing block 55, thereby fixing the two protective plates 54. The two protective plates 54 can protect one side of the searchlight 4, which helps to prevent debris from directly hitting the searchlight 4's illumination side when carrying the flaw detection instrument or when the flaw detection instrument is idle.

[0042] When the searchlight 4 is needed, push the two protective plates 54 in the opposite direction to disengage the rubber block 57 from the inner wall of the fixing block 55. The spring 58 will then reset and move the two protective plates 54 away from each other until one side of the searchlight 4 is completely unobstructed, facilitating the quick use of the searchlight 4. After the power cord terminal is connected to the interface terminal 6, push the two clamping plates 73 towards the interface terminal 6. The clamping plates 73 will cause the sliding rod 77 to slide on the inner wall of the second L-shaped plate 71 and the threaded rod 72 to slide on the inner wall of the second L-shaped plate 71 until the rubber plate 75 on one side of the two clamping plates 73 completely clamps the power cord terminal. Then rotate the nut 74 so that one side of the nut 74 abuts against one side of the second L-shaped plate 71. The nut 74 can limit the threaded rod 72 and the clamping plates 73. The two clamping plates 73 provide auxiliary fixation between the power cord terminal and the interface terminal 6, which helps to prevent the power cord terminal from separating from the interface terminal 6.
