Description

Technical Field

[0001] The present application relates to the technical field of detection equipment, and in particular to a detector mounting structure and a sphericity detection device. Background Art

[0002] The contents of this section merely provide background information related to the present application and may not constitute prior art.

[0003] In the field of monitoring equipment, spherical covers are widely used and suitable for various indoor and outdoor environments, such as traffic flow monitoring, school and hospital security, public place safety, etc. Due to the changeable outdoor environment, rain, snow, fog, clear weather, cloudy and sunny changes, etc. will cause impressions on the monitoring screen. The fundamental reason is that the light changes caused by environmental changes will affect the lighting of the monitoring equipment lens. In addition, natural weather such as wind, sand, rain and snow will also have a certain impact on the reliability and monitoring quality of the monitoring equipment. Therefore, the spherical cover can not only protect the monitoring equipment, but also reduce the impact of light changes on the monitoring quality, enhance the quality of lighting and imaging of the equipment lens, and ultimately achieve the effect of improving the monitoring quality.

[0004] For spherical covers, the higher the sphericity accuracy of the spherical cover, the clearer the video images taken by the surveillance camera can be. Therefore, in today's social production, especially with the popularization of 4K and even 8K imaging equipment, the demand for high-precision spherical covers is also increasing. For monitoring equipment, it is often no longer the shooting lens but the accuracy of the spherical cover that limits the imaging quality. With the development of industrial production technology, the production problem of high-precision spherical covers has been solved. However, a certain defective rate is inevitable in industrial production. Therefore, it is necessary to perform sphericity detection on the completed spherical covers to eliminate defective products.

[0005] When testing a spherical cover body, the spherical cover body to be tested must first be placed on a testing table, and then a detector of a suitable model is selected according to the size of the spherical cover body to be tested, and the detector is installed on the mounting rod above the testing table. After the installation of the detector is completed, the sphericity of the spherical cover body can be tested; however, in the above process, whenever it is necessary to test spherical covers of different sizes, the detector must be replaced, and the installation accuracy of the detector directly affects the subsequent detection accuracy. At the same time, the speed of replacing the detector also directly affects the detection efficiency. Existing detectors are usually installed on the mounting rod by bolt connection. It is difficult to ensure rapid installation between multiple bolts, and large errors may occur in the installation, which affects the detection accuracy and efficiency. Utility Model Content

[0011] In some possible embodiments, the anti-slip portion is configured as a retaining edge, and the anti-slip portion is fixedly arranged on the inner wall of the hole opening of the mounting hole along the vertical direction. A protrusion is fixedly arranged on the side wall of the limiting member, and the protrusion is used to abut against one side of the anti-slip portion located in the mounting hole to limit the deflection angle of the limiting member in the mounting hole.

[0012] In some possible embodiments, a sliding layer is provided on a side of the limiting member away from the mounting block, and the sliding layer is used for being slidably connected to a bottom notch of the mounting groove.

[0013] In some possible embodiments, an abutment portion is slidably arranged at the top of the mounting block along the vertical direction, and the top of the abutment portion is used to abut against the inner top wall of the mounting groove.

[0020] In summary, the technical solution of the embodiment of the present application has at least the following advantages and beneficial effects:

[0021] 1. In actual use, the mounting block is inserted into the mounting slot from the bottom of the mounting slot. The mounting block simultaneously drives the limit piece to move upward in the mounting slot, and finally drives the limit piece to be snapped into the snap slot, thereby limiting the position of the mounting block in the mounting slot. At this time, the position of the fixed plate and the detector on the mounting portion is also limited. When the detector needs to be disassembled, the mounting block is continued to be driven to move upward in the mounting slot. When the limit piece moves to the through hole, it can be removed from the limit piece through the through hole, thereby removing the mounting block from the mounting slot. At this time, the mounting block can be taken out to realize the disassembly of the detector. The operation is convenient and fast, and the work efficiency is high. At the same time, it is not connected by bolts, and the horizontal accuracy is reliable, thereby ensuring the accuracy of subsequent sphericity detection.

[0022] 2. In the process of driving the limit piece to fit into the limit groove, the limit piece first enters the installation groove through the notch at the bottom of the installation groove. During the entry process, sliding friction occurs between the limit piece and the notch of the installation groove. By setting a sliding layer, the friction coefficient between the limit piece and the notch at the bottom of the installation groove can be effectively reduced, thereby reducing the friction force generated between the limit piece and the notch at the bottom of the installation groove, thereby improving the convenience of installation and reducing wear.

[0023] 3. After the detector is installed, the top of the abutting portion abuts against the inner top wall of the mounting groove. At this time, the second elastic member is in a compressed state, acting on the mounting block to make the mounting block tend to move downward, thereby pressing the limit member tightly into the slot, which can effectively reduce the shaking and deviation of the mounting block during the detection process, and at the same time improve the reliability of the device during actual use.

[0024] 4. In actual use, the mounting part can be disassembled from the mounting rod as a whole, and the internal structure of the mounting part can be repaired and maintained, thereby increasing the service life of the entire device.

[0025] In summary, the utility model can improve the accuracy of detector installation, and for different spherical cover detection workpieces, the application can facilitate the replacement of detectors, thereby improving the efficiency of spherical cover detection.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] The following reference Figures 1 to 7 This application is described in further detail.

[0036] In one aspect, the present application provides a detector mounting structure.

[0037] Reference Figure 1 A detector mounting structure includes a mounting portion 1, the mounting portion 1 is an inverted "L" shaped structure, including a horizontal plate and a vertical plate, the horizontal plate is used to connect with the mounting rod 62 of the sphericity detection device, specifically as Figure 7 A mounting groove 11 is provided on the vertical plate of the mounting portion 1 in the vertical direction, the bottom of the mounting groove 11 is penetrated downward, a mounting block 12 is slidably provided in the mounting groove 11, a fixing plate 13 is provided on the mounting block 12, and a detector 2 is provided on the fixing plate 13. Figure 1 The attached figure is an exploded view, so Figure 1 The connection between the fixing plate 13 and the mounting block 12 is not shown in FIG. Figure 7 shown.

[0038] Furthermore, a partition 14 may be provided between the mounting block 12 and the fixing plate 13, one side of the partition 14 being fixedly connected to the side wall of the mounting block 12, and the other side being fixedly connected to the side wall of the fixing plate 13. Due to the provision of the partition 14, a certain gap exists between the fixing plate 13 and the mounting block 12.

[0039] Reference Figure 1 The detector 2 includes a detection probe 21 and a rotating motor 22. The rotating motor 22 is fixedly mounted on the side wall of the fixed plate 13 away from the mounting block 12. The detection probe 21 is fixedly connected to the output shaft of the rotating motor 22, and the detection probe 21 can be driven to rotate by the rotating motor 22. In actual use, the detection probe 21 can be driven to deflect within a certain angle range by the rotating motor 22, thereby improving the comprehensiveness and accuracy of the sphericity detection of the inner circumference of the spherical cover workpiece.

[0040] During the operation of the rotating motor 22, the rotating motor 22 will generate a certain amount of heat. By setting the partition 14 to create a gap between the fixing plate 13 and the mounting block 12, the heat dissipation efficiency of the rotating motor 22 can be effectively improved, thereby protecting the rotating motor 22 and increasing the service life of the rotating motor 22.

[0041] Reference Figure 2 A limiting member 3 is arranged on the side wall of the mounting block 12, a slot 31 for the limiting member 3 to be inserted is provided on the side wall of the mounting groove 11, and a through hole 32 connected to the slot 31 is provided on the side of the mounting portion 1 close to the fixing plate 13, that is, the through hole 32 is provided on the left and right sides of the slot opening of the mounting groove 11 close to the fixing plate 13, and the slot 31 is provided on the two sides of the slot wall of the mounting groove 11 away from the fixing plate 13, and the through hole 32 is located outside the slot 31. The through hole 32 is used for the limiting member 3 to pass through, and the lower edge of the through hole 32 is higher than the lower edge of the slot 31.

[0042] Preferably, the lower edge of the through hole 32 is 3-5 mm higher than the lower edge of the slot 31 .

[0043] As an implementation method of this application, refer to Figure 2 The limiting member 3 is configured as a limiting sheet. Preferably, the limiting sheet is configured as a spring sheet having a certain elastic modulus. Two limiting members 3 are provided. The two limiting members 3 are respectively provided on both sides of the mounting block 12. The top of the limiting member 3 is fixedly connected to the side wall of the mounting block 12. Specifically, the upper end of the limiting member 3 is obliquely inserted into the socket provided on the side wall of the mounting block 12 and fixed, forming a Figure 2The bottom end of the stopper 3 is lifted off the mounting block 12 and a gap is formed between the stopper 3 and the mounting block 12. When the bottom end of the stopper 3 is lifted off the mounting block 12, a "human" shaped structure is formed between the stopper 3 and the side wall of the mounting block 12. The side of the stopper 3 away from the mounting block 12 can be slidably connected with the groove wall of the mounting groove 11. When the stopper 3 is pushed into the slot 31, the bottom end of the stopper 3 abuts against the bottom wall of the slot 31 to limit the position of the mounting block 12 in the mounting groove 11.

[0044] In actual use, when the detector 2 needs to be installed, the mounting block 12 is first driven to be inserted into the mounting groove 11 through the opening at the bottom of the mounting groove 11, and then the mounting block 12 is driven to move upward in the mounting groove 11, and the mounting block 12 drives the limiting member 3 to move upward until the side of the limiting member 3 away from the mounting block 12 abuts against the notch at the bottom of the mounting groove 11. At this time, as the mounting block 12 continues to move upward, the limiting member 3 deflects and contracts toward the mounting block 12 under the action of the groove wall of the mounting groove 11 until the limiting member 3 falls into the card groove 31, as shown in FIG. Figure 2 As shown, at this time, the lower end of the limiting member 3 is deflected in the direction away from the mounting block 12 under the action of its own elastic force, so that the lower end of the limiting member 3 is inserted into the slot 31, and the position of the mounting block 12 in the mounting slot 11 can be limited.

[0045] When the detector 2 needs to be disassembled, Figure 3 As shown, the mounting block 12 is driven to continue to move upward, and the mounting block 12 drives the limiting member 3 to move upward in the slot 31. Since the lower edge of the through hole 32 is higher than the lower edge of the slot 31, the mounting block 12 needs to drive the limiting member 3 to move upward in the slot 31 for a certain distance before the limiting member 3 can be separated from the slot 31 through the through hole 32, thereby driving the mounting block 12 to separate from the mounting slot 11. At this time, the mounting block 12 can be taken out to complete the disassembly of the detector 2.

[0046] As an embodiment of the present application, a sliding layer is covered on the side of the limit member 3 away from the mounting block 12, and the sliding layer is used to be slidingly connected to the groove wall of the mounting groove 11. The specific material of the sliding layer is set to polytetrafluoroethylene (Teflon), which can effectively reduce the friction coefficient between the limit member 3 and the bottom groove of the mounting groove 11, thereby reducing the friction force on the limit member 3, making it convenient for the staff to drive the mounting block 12 to move.

[0047] Reference Figure 2 A contact portion 4 is slidably provided at the top of the mounting block 12 in the vertical direction, and the top of the contact portion 4 is used to abut against the inner top wall of the mounting groove 11. A second elastic member 41 is provided on the mounting block 12, and the second elastic member 41 is used to drive the contact portion 4 to move in a direction away from the mounting block 12, thereby having the potential energy to push the mounting block 12 toward the bottom of the mounting groove 11.

[0048] Reference Figure 2 , 3 A receiving hole 42 is opened in the top of the mounting block 12 in the vertical direction, the abutment portion 4 is slidably arranged in the receiving hole 42 in the vertical direction, and the second elastic member 41 is arranged in the receiving hole 42. As an embodiment of the present application, the second elastic member 41 is arranged as a compression spring, one end of the second elastic member 41 abuts against the bottom of the abutment portion 4, and the other end abuts against the inner bottom wall of the receiving hole 42. As an embodiment of the present application, the elastic modulus of the second elastic member is greater than the elastic modulus of the limiting member itself.

[0049] During actual use, after the position of the mounting block 12 in the mounting groove 11 is defined, the top of the abutting portion 4 abuts against the inner top wall of the mounting groove 11, and the second elastic member 41 is in a compressed state. The second elastic member 41 acts on the mounting block 12, causing the mounting block 12 to have a downward movement tendency. At this time, the lower edge of the limiting member 3 abuts against the bottom of the card slot 31 to define the position of the mounting block 12, thereby ensuring that the limiting member 3 will not be separated from the card slot 31 through the through hole 32 due to vibration of the machine or human error, thereby effectively improving the reliability and stability of the device during actual use.

[0050] As an implementation mode of the present application, when the limiting member 3 is set as a limiting plate, there is a certain gap between the side wall of the mounting block 12 and the inner wall of the mounting groove 11, and the size of the gap is adapted to the thickness of the limiting member 3. When the mounting block 12 is installed, the limiting member 3 is deflected toward the mounting plate under the action of the groove wall of the mounting groove 11, and the limiting member 3 undergoes elastic deformation to store a certain elastic potential energy. The gap between the side wall of the mounting block 12 and the inner wall of the mounting groove 11 is used to accommodate the limiting member 3 after the deflection. When the limiting member 3 is located in the card slot 31, the limiting member 3 is deflected in the direction away from the mounting block 12 and releases the elastic potential energy previously stored. At this time, the limiting member The lower end of the second elastic member 41 is inserted into the slot 31, thereby limiting the height position of the mounting block 12 in the mounting slot 11. At the same time, since the second elastic member 41 is in a compressed state, the mounting block 12 has a downward movement tendency under the action of the second elastic member 41. The mounting block 12 applies a downward force to the limiting member 3, thereby pressing the bottom end of the limiting member 3 against the inner wall of the slot 31. On the one hand, the position of the limiting member 3 in the vertical direction is limited, and on the other hand, the position of the limiting member 3 in the horizontal direction is also limited, so as to avoid the limiting member 3 from shaking in the horizontal direction, thereby further improving the detection accuracy and stability of the device during the detection process.

[0051] As another embodiment of the present application, refer to Figure 4The limiting member 3 is configured as a limiting block, and mounting holes 5 are provided on both side walls of the mounting block 12. The limiting member 3 is disposed in the mounting hole 5. A side of the limiting member 3 away from the mounting hole 5 is configured as an inclined surface 51. In the direction from the outside to the inside of the mounting hole 5, the inclined surface 51 is inclined upward, and the inclined surface 51 is used for sliding connection with the groove wall of the mounting groove 11. A mounting shaft 52 is rotatably provided in each mounting hole 5, and the top of the limiting member 3 is fixedly connected to the mounting shaft 52. A first elastic member 53 is provided in the mounting hole 5, and the first elastic member 53 is used to drive the limiting member 3 to deflect in a direction away from the mounting hole 5.

[0052] like Figure 5 As shown, an anti-slip portion 54 is provided on the mounting block 12, and the anti-slip portion 54 is used to limit the deflection angle of the limiting member 3. When the limiting member 3 is located in the slot 31, the bottom of the limiting member 3 abuts against the bottom of the slot 31 to limit the position of the mounting block 12 in the mounting slot 11.

[0053] As an implementation method of this application, refer to Figure 4 The first elastic member 53 is configured as a torsion spring and is sleeved on the mounting shaft 52. One end of the first elastic member 53 is fixedly connected to the mounting shaft 52, and the other end is fixedly connected to the side wall of the mounting hole 5. Two first elastic members 53 are provided, and the two first elastic members 53 are respectively arranged at both ends of the mounting shaft 52.

[0054] Reference Figure 4 , 5 The anti-slip part 54 is set as a retaining edge, and the anti-slip part 54 is fixedly set on the inner wall of the hole of the mounting hole 5 in the vertical direction. A protrusion 55 is fixedly set on the side wall of the limiter 3, and the protrusion 55 is used to abut against the side of the anti-slip part 54 located in the mounting hole 5 to limit the deflection angle of the limiter 3 in the mounting hole 5. In actual use, the mounting shaft 52 has a deflection movement tendency under the action of the first elastic member 53, thereby driving the limiter 3 to have a movement tendency to deflect in the direction away from the mounting hole 5. At this time, the position of the limiter 3 in the mounting hole 5 is limited by the protrusion 55 and the anti-slip part 54, which can prevent the limiter 3 from being separated from the mounting hole 5, and facilitate the subsequent disassembly of the detector 2.

[0055] On the other hand, the present application also provides a sphericity detection device.

[0056] Reference Figure 6 A sphericity detection device includes a frame 6 and a detector mounting structure as described above, wherein a detection table 61 is arranged in the frame 6, and a mounting rod 62 is arranged in the frame 6 along the vertical direction, and the mounting rod 62 is located above the detection table 61.

[0057] Among them, refer to Figure 6 , 7A connecting plate 63 is fixedly provided at the bottom of the mounting rod 62, and a through hole 64 is provided on the connecting plate 63 which passes through the connecting plate 63 from top to bottom. There are four through holes 64, which are respectively arranged at the four corners of the connecting plate 63. A connecting bolt 65 is slidably inserted in each through hole 64, and a connecting hole 66 for threaded connection of the connecting bolt 65 is provided at the top of the mounting portion 1.

[0058] During actual use, the mounting part 1 can be removed from the mounting rod 62 as a whole, and the internal structure of the mounting part 1 can be repaired and maintained, thereby increasing the overall service life of the device. The mounting part 1 and the connecting plate 63 are connected by connecting bolts 65, which is simple, reliable and has good practicality.

[0059] In a normal detection process, different detectors 2 are selected for different models of spherical cover bodies to be detected, and the detectors 2 are disassembled and installed on the mounting part 1. The number of times the detector 2 is disassembled and installed is related to the model of the spherical cover body to be detected. When it is necessary to detect the sphericity of multiple spherical cover bodies, the detector 2 needs to be disassembled and installed multiple times. In the prior art, when the detector 2 is disassembled and installed by bolts, the detector 2 needs to be recalibrated for accuracy each time it is installed, which makes it difficult to ensure the accuracy and efficiency of the detection. The present application disassembles and installs the detector 2 by a sliding connection, which improves the installation accuracy, avoids multiple calibrations, and further improves the detection efficiency. The position of the mounting part 1 on the mounting rod 62 is usually installed and disassembled only once within a complete detection cycle. Therefore, there is no problem of multiple disassembly of the mounting part 1 affecting the accuracy. Therefore, the mounting part 1 is connected and fixed on the mounting rod 62 by connecting bolts 65, which can reduce costs.

[0060] In actual use, when it is necessary to detect the sphericity of the workpiece to be detected, first place the workpiece to be detected on the detection table 61, and then install the detector 2. First, drive the mounting block 12 to insert into the mounting groove 11 through the opening at the bottom of the mounting groove 11, and then drive the mounting block 12 to move upward in the mounting groove 11. The mounting block 12 drives the limit member 3 to move upward until the side of the limit member 3 away from the mounting block 12 abuts against the bottom groove of the mounting groove 11. At this time, as the mounting block 12 continues to move upward, the limit member 3 deflects and shrinks toward the mounting block 12 under the action of the groove wall of the mounting groove 11 until the limit member 3 falls into the card groove 31. At this time, the position of the mounting block 12 in the mounting groove 11 can be limited, thereby completing the installation of the detector 2. Then start the detector 2 to detect the sphericity of the workpiece to be detected. During the detection process, start the rotating motor 22. The rotating motor 22 drives the detection probe 21 to deflect within a certain angle range, which can perform a more precise detection of the sphericity of the workpiece to be detected.

[0061] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
