Description

Technical Field

[0001] The utility model belongs to the field of light-proof pipes, and particularly relates to a light-proof pipe grinding and processing device. Background Art

[0002] With the stringent requirements of special high-performance equipment on the working light environment, some pipes are required to be light-proof, and light-proof pipes came into being.

[0003] The light-proof tube uses light-proof paint on the inner wall of the tube to minimize the reflection of incident light while ensuring that external light can enter the tube. Among light-proof tubes, those with a length of 3000mm and a diameter of 50mm-100mm are ultra-long, small-diameter glass fiber reinforced polymer-based light-proof tubes, which pose great challenges to the treatment of the inner wall, the coating of light-proof paint, and the detection of light leakage. The small diameter and ultra-long length make it impossible for general tools to operate normally.

[0004] Before applying light-proof paint to extra-long and small-diameter light-proof tubes, it is crucial to grind the inner wall. However, the characteristics of extra-long and small-diameter light-proof tubes bring technical difficulties to the grinding work. Because the diameter is too large, the grinding head of the grinding device cannot penetrate into the interior of the light-proof tube; if the grinding head is set too small, the durability of the grinding head will be relatively poor and the grinding efficiency will be low. Utility Model Content

[0005] In view of this, the utility model aims to provide a light-shielding tube grinding and processing device to solve the problem of difficulty in grinding super-long and small-diameter light-shielding tubes.

[0006] In order to achieve the above-mentioned purpose, a light-shielding tube polishing device is provided, comprising:

[0007] A light-shielding tube fixing mechanism, including a fastening assembly for fixing the light-shielding tube;

[0008] The grinding mechanism includes a driver, a rod connected to the rotating end of the driver, and a grinding head assembly connected to the distal end of the rod. The diameter of the grinding head assembly is larger than the inner diameter of the light-proof tube. The grinding head assembly includes a flexible layer that can be compressed along the radial direction of the light-proof tube and a grinding layer sleeved on the circumferential side of the flexible layer. The flexible layer is used to support the grinding layer to adhere to the inner wall of the light-proof tube when grinding the inner wall of the light-proof tube.

[0009] Furthermore, the light-shielding tube fixing mechanism also includes a base, and the fastening assembly is connected to the base.

[0010] Furthermore, the number of the fastening components is at least two and they are arranged at intervals along the axial direction of the light-shielding tube.

[0011] Furthermore, the fastening assembly is in an annular shape as a whole and comprises a fastening lower ring and a fastening upper ring connected to each other, and one end of the base is connected to the fastening lower ring.

[0012] Furthermore, the rod member includes a driver connector, a hollow grinding rod and a grinding head connector, wherein one end of the driver connector is connected to the driver rotating end and the other end is connected to the hollow grinding rod, and the other end of the hollow grinding rod is connected to the grinding head connector.

[0013] Furthermore, the driver connecting piece and the grinding head connecting piece are both stepped cylindrical.

[0014] Furthermore, the driver connector and the grinding head connector are both bonded and connected to the hollow grinding rod.

[0015] Furthermore, the grinding head assembly also includes a connecting rod and an inner core, one end of the connecting rod is connected to the grinding head connecting piece, and the other end is connected to the inner core, and the flexible layer is sleeved on the peripheral wall of the inner core.

[0016] Furthermore, the connecting rod is a threaded rod.

[0017] Furthermore, the fixed light-proof tube is a glass fiber reinforced polymer-based light-proof tube.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The device supports the grinding layer by setting a flexible layer. In this way, under the premise that the diameter of the grinding head assembly is larger than the inner diameter of the light-proof tube, the grinding head assembly can enter the light-proof tube through reasonable compression and the grinding layer can be well attached to the inner wall of the light-proof tube. In this way, the small-diameter light-proof tube can be polished and the excessive consumption of the grinding head assembly can be prevented;

[0020] 2. This device can reduce the weight of the entire grinding mechanism by setting a hollow grinding rod to connect the grinding head and the driver. Because the light-proof rod is long, the use of a hollow grinding rod can reduce the overall weight. When grinding by hand, it can reduce the load of the operator. When the machine is used for carrying, it can also reduce power consumption. The length of the hollow grinding rod can be set to be slightly longer than half the length of the light-proof tube. In this way, grinding from both sides once can completely cover the entire length of the light-proof tube.

[0021] 3. This device can detect whether there is light transmission by setting a light source to coaxially inject light into the light-proof tube and rotating the light-proof tube. It can cooperate with the brushing mechanism to apply light-proof paint, which can ensure good coating of the light-proof paint and reduce the occurrence of light leakage defects.

Therefore, it cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0037] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Referring to the accompanying drawings, this embodiment is described. According to one aspect of the utility model, a light-shielding tube processing device is provided, comprising:

[0039] The light-shielding tube fixing mechanism 1 comprises a fastening assembly for fixing the light-shielding tube 5; after the light-shielding tube 5 is fixed by the fastening assembly, it is convenient to grind the inner wall of the light-shielding tube 5 and to apply light-shielding paint to the grinded inner wall.

[0040] The light source mechanism 2 is arranged on one side of the light-proof tube 5 for incident light into the light-proof tube 5; it should be noted that no matter what form the light source mechanism 2 is arranged in, it is necessary to ensure that the light of the light source can be incident from one end of the light-proof tube 5 and emitted from the other end coaxially, so that the light can be completely transmitted in the light-proof tube 5, so that when the light-proof paint is tested for light leakage, the whole picture of the light-proof tube 5 can be observed at one time, and the observation and detection efficiency is high. If necessary, the corresponding fastening component can be made of transparent material, so that it is convenient to observe whether the light-proof tube 5 has light leakage when the light-proof tube 5 cannot be rotated. The light-proof tube fixing mechanism 1 and the light source mechanism 2 are both installed on the platform 6. The flatness of the platform 6 ensures that the light-proof tube fixing mechanism 1, the light source mechanism 2 and the light-proof tube 5 are coaxial with the light after installation.

[0041] The grinding mechanism 3 includes a driver 3-1, a rod connected to the rotating end of the driver 3-1, and a grinding head assembly 3-5 connected to the distal end of the rod. The diameter of the grinding head assembly 3-5 is larger than the inner diameter of the light-shielding tube 5. The grinding head assembly 3-5 includes a flexible layer 3-5-3 that can be compressed along the radial direction of the light-shielding tube 5 and a grinding layer 3-5-4 sleeved on the circumference of the flexible layer 3-5-3. The flexible layer 3-5-3 is used to support the grinding layer 3-5-4 to fit on the inner wall of the light-shielding tube 5 when grinding the inner wall of the light-shielding tube 5. When the inner wall of the light-proof tube 5 is polished, the rod is driven to rotate by the driver 3-1, and the rotation of the rod can drive the coaxially arranged polishing head assembly 3-5 to rotate. Since a flexible layer 3-5-3 that can be compressed in the radial direction is provided in the polishing head assembly 3-5, under the premise that the diameter of the overall polishing head assembly 3-5 is larger than the inner diameter of the light-proof tube 5, the polishing head assembly 3-5 can be inserted into the light-proof tube 5 to polish the inner wall of the light-proof tube 5 by reasonably compressing the flexible layer 3-5-3. During the polishing process, since the flexible layer 3-5-3 has a certain support, it can ensure that the flexible layer 3-5-3 supports the polishing layer 3-5-4, thereby ensuring that the polishing layer 3-5-4 is always attached to the inner wall of the light-proof tube 5 during the rotation polishing process, and ensuring that the polishing efficiency is maintained at a high level. As for the selection of materials for the flexible layer 3-5-3, a flexible soft foam layer can be selected. The flexible soft foam layer is easy to obtain and inexpensive, which can reduce the cost of use and replacement. For the polishing layer 3-5-4, materials such as sandpaper can be selected, and the corresponding roughness is selected according to the actual polishing technical requirements. For the light-proof tube 5 to be processed in this application, it is generally around 60-120 mesh. After polishing to the standard of technical requirements, use compressed air to blow away the polishing dust on the inner wall of the tube, and then wipe the inner surface with a special cleaning agent before entering the light-proof paint coating stage. For the specific selection of the driver 3-1, the most economical selection is a hand drill.

[0042] The brushing mechanism 4 is used for brushing the light-proof paint on the inner wall of the light-proof tube 5 .

[0043] In the present embodiment, the light-shielding tube fixing mechanism 1 further includes a base 1-1, and the fastening assembly is connected to the base 1-1. The fastening assembly is in an annular shape as a whole and includes a fastening lower ring 1-2 and a fastening upper ring 1-3 that are connected to each other, and one end of the base 1-1 is connected to the fastening lower ring 1-2. Specifically, the fastening lower ring 1-2 and the fastening upper ring 1-3 can be connected by bolts, or by snap-fitting, and the connection method is selected according to actual needs. As an alternative, sliding balls can be provided in the fastening lower ring 1-2 and the fastening upper ring 1-3, which can allow the light-shielding tube 5 to rotate along its own axis to a certain extent while satisfying the overall fixation of the light-shielding tube 5. When checking whether the light-shielding tube 5 has a light-shielding paint leakage defect, the light-shielding tube 5 can be rotated and observed. The flexibility of rotation should not be too large to prevent the light-shielding tube 5 from rotating and affecting the polishing when the light-shielding tube 5 is polished. An additional clamping assembly can also be used to further fix the light-shielding tube 5, so as to ensure that the light-shielding tube 5 can ensure its own fixation during the polishing stage. When there is a light leakage defect in the light-shielding paint, the light-shielding tube 5 can be rotated to facilitate light leakage observation.

[0044] In this embodiment, the light source mechanism 2 includes a light source support base 2-1, a light source fixing ring 2-2 and a light source 2-3, one end of the light source support base 2-1 is connected to the light source fixing ring 2-2, the light source fixing ring 2-2 is connected to the light source 2-3, and the light of the light source 2-3 is coaxial with the light-shielding tube 5.

[0045] In this embodiment, the rod member includes a driver connector 3-2, a hollow grinding rod 3-3 and a grinding head connector 3-4, one end of the driver connector 3-2 is connected to the rotating end of the driver 3-1, and the other end is connected to the hollow grinding rod 3-3, and the other end of the hollow grinding rod 3-3 is connected to the grinding head connector 3-4. For the hollow polishing rod 3-3, the hollow structure can be well adapted to the use conditions of the extra-long and small-diameter light-proof tube 5. Because the light-proof tube 5 is long and small in diameter, a longer length is required for polishing it, so a longer cantilever structure is needed to support the polishing head. The use of a hollow polishing rod can reduce the overall weight, reduce the load of the operator or the load of the machine. For the material selection of the hollow polishing rod 3-3, an epoxy carbon fiber thin-walled tube can be selected, which can meet the structural strength and reduce the overall weight. For the length selection of the hollow polishing rod 3-3, too long will increase the cantilever length, and deformation will inevitably occur, affecting the polishing effect. Therefore, the length of the hollow polishing rod 3-3 is set to be slightly longer than half the length of the light-proof tube 5. In this way, during the polishing process, the hollow polishing rod 3-3 is respectively inserted into the bearing polishing head assembly from both sides of the light-proof tube 5 for polishing, and the polishing efficiency is high. The same light-proof tube 5 only needs two polishings to complete the polishing work, and can overcome the disadvantages of the long cantilever, and the polishing efficiency and polishing accuracy are improved. The driver connector 3-2 and the polishing head connector 3-4 can be set as metal processing parts, and can be connected to the hollow polishing rod 3-3 by bonding, or by snap-fitting or bolting. However, for snap-fits or bolts, it is easy to cause looseness when the cantilever is too long. The best way is bonding. By setting the driver connector 3-2 and the polishing head connector 3-4 to the shape of a stepped cylinder, the hollow polishing rod 3-3 is sleeved on the driver connector 3-2 and the polishing head connector 3-4 and snapped on the step. By bonding, a reliable connection advantage can be obtained, and the connection process is simple and efficient.

[0046] In this embodiment, the grinding head assembly 3-5 also includes a connecting rod 3-5-1 and an inner core 3-5-2. One end of the connecting rod 3-5-1 is connected to the grinding head connector 3-4, and the other end is connected to the inner core 3-5-2. The flexible layer 3-5-3 is sleeved on the peripheral wall of the inner core 3-5-2. The connecting rod 3-5-1 can be connected to the grinding head connector 3-4 by means of a snap or a bolt, which is selected according to actual needs. For the inner core 3-5-2, it can be made of wood material, and the specific shape can be cylindrical or rectangular. The cylindrical shape is convenient for meeting the coaxiality between the inner core 3-5-2 and the rotating end of the driver, while the rectangular shape can improve the adhesion between it and the flexible layer 3-5-3, which is selected according to actual needs. The connecting rod 3-5-1 is hollow, which can also reduce weight and reduce the deformation effect caused by the cantilever.

[0047] In this embodiment, the brushing mechanism 4 includes a handheld portion 4-1, a hollow roller brush rod 4-2, a roller brush fixing member 4-3 and a roller brush assembly 4-4, one end of the hollow roller brush rod 4-2 is connected to the handheld portion 4-1, and the other end is connected to one end of the roller brush fixing member 4-3, and the other end of the roller brush fixing member 4-3 is connected to the roller brush assembly 4-4. The hollow roller brush rod 4-2 is set to be hollow, which is also based on the consideration of reducing the weight of the cantilever. A rubber sleeve or the like can be set on the outside of the handheld portion 4-1, which can improve the comfort of holding and increase the friction, making it more secure when the user grasps it. The roller brush fixing member 4-3 and the hollow roller brush rod 4-2 can also be in the form of buckles, bolts or glue. For the glue form, refer to the connection form between the hollow grinding rod 3-3 and the driver connector 3-2, which will not be repeated here.

[0048] In this embodiment, the roller brush assembly 4-4 includes a roller brush connecting rod 4-4-1, a hair roller 4-4-2 and a base roller 4-4-3. One end of the roller brush connecting rod 4-4-1 is connected to the roller brush fixing member 4-3, and the other end is connected to the base roller 4-4-3. The hair roller 4-4-2 is coaxially coupled with the peripheral wall of the base roller 4-4-3. The roller brush connecting rod 4-4-1 and the roller brush fixing member 4-3 are connected by bolts. Specifically, a thread is set on the roller brush connecting rod 4-4-1, and bolts are set on both sides of the base roller 4-4-3 to match the thread, so that the base roller 4-4-3 is fixed between two double bolts. This fixing method is easy to obtain materials and has reliable connection, which reduces costs. The size of the hair roller 4-4-2, especially the outer diameter, is generally about one-third to one-half of the inner diameter of the light-shielding tube body. The existing roller brushes on the market can be purchased for modification or homemade.

[0049] According to another aspect of the utility model, a method for applying light-shielding paint using the above-mentioned light-shielding tube processing device is provided, characterized in that it includes the following steps: immersing the roller brush assembly 4-4 into the prepared light-shielding paint, and controlling the amount of light-shielding paint contained in the roller brush fixing part 4-3, and applying it on the inner wall of the light-shielding tube 5 within a certain period of time, based on the light-shielding paint not flowing when the roller brush fixing part 4-3 is suspended, and repeatedly dipping and brushing until all the inner walls are evenly coated with light-shielding paint is one coating. Apply multiple times as required, and wait for the paint film to dry before applying the next time until multiple coatings are completed.

[0050] According to another aspect of the utility model, a light transmission detection method using the above-mentioned light-shielding tube processing device is provided, comprising the following steps:

[0051] S1. Fix the light-proof tube 5 coated with light-proof paint in a relatively dark place; specifically, fix the light-proof tube 5 between the lower fastening ring 1-2 and the upper fastening ring 1-3. To increase the stability of the light-proof tube 5, at least two sets of lower fastening rings 1-2 and upper fastening rings 1-3 are arranged along the axial direction of the light-proof tube 5, which can improve the fixing stability of the light-proof tube 5. It is set in a relatively dark place to observe whether there is light leakage.

[0052] S2, place the light source mechanism 2 at the tube opening on one side of the light-shielding tube 5 and inject light into the light-shielding tube 5; the light enters from the tube opening on one side of the light-shielding tube 5 and exits from the tube opening on the other side, so that the light-shielding tube 5 can be observed over the entire length, thereby improving the observation efficiency. For the light source mechanism 2, a strong light flashlight can be selected for use.

[0053] S3. Rotate the light-proof tube 5 and observe whether there is light leakage. The selection is made here according to actual needs. Whether the light-proof tube 5 can be rotated depends on the specific structural form of the lower fastening ring 1-2 and the upper fastening ring 1-3. If it is fixed, the lower fastening ring 1-2 and the upper fastening ring 1-3 can be set to transparent material. In this way, it is possible to detect whether there is light leakage in the light-proof tube 5 as a whole without rotating the light-proof tube 5.

[0054] S4, brushing the light leaking part with the brushing mechanism 4 until there is no light leakage in the light-shielding tube 5, and the inspection and repair are completed.
