Description

Technical Field

[0001] The utility model relates to the field of cavity filters, and particularly relates to a spraying fixture for a cavity filter with a rotation adjustment structure. Background Technique

[0002] The cavity filter is integrally cut from metal, has a good frequency selection and filtering effect in circuits and electronic high-frequency systems, can suppress useless signals and noise outside the frequency band, and is applied in aviation, aerospace, radar, communication, electronic countermeasure, radio and television, and various electronic test equipment. During the production process of the cavity filter, painting treatment is required, and during the painting process, the cavity filter needs to be clamped and fixed to improve the painting effect.

[0003] After retrieval, a spraying device for the production of a utility model cavity filter with a publication number of CN211887512U relates to the field of spraying technology. The spraying device for the production of the cavity filter includes a spraying vertical plate, a cavity is arranged inside the spraying vertical plate, a dividing net is arranged inside the cavity, the dividing net is fixedly connected with the spraying vertical plate, a storage bin is arranged on one side of the dividing net, an extrusion bin is arranged on one side of the storage bin, a piston plate is arranged inside the extrusion bin, the extrusion bin is slidably connected with the piston plate, and a push rod is fixedly connected to the top of the piston plate. The spraying device for the production of the cavity filter adjusts the discharge amount during spraying by setting an active limiting component to make the spraying more uniform. The structure of the utility model is simple and reasonable, avoiding the problem that the spraying cannot be guaranteed to be very uniform during spraying, which affects the quality of the cavity filter, making the inner wall of the cavity filter more uniform during spraying, improving the spraying accuracy, and significantly improving the production quality of the cavity filter.

[0004] The existing cavity filter painting fixtures basically use single-sided clamping of the cavity filter for painting treatment, and the cavity filter painting fixtures rarely have a rotation function. Therefore, when painting other angles of the cavity filter, it is necessary to manually remove and adjust it. The cavity filter painting device in the above comparison case only simply uses a limit block to clamp the cavity filter and does not have a rotation function either. It can only manually adjust the height and painting angle of the cavity filter by hand, resulting in a delay in the painting work efficiency.

[0005] Therefore, it is very necessary to invent a spraying fixture for a cavity filter with a rotation adjustment structure to solve the above problems. Content of the Utility Model

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] The present utility model provides a spraying fixture for a cavity filter with a rotation adjustment structure as Figures 1-5 shown, which includes a base 1;

[0029] A lead screw 3 is movably arranged inside the base 1 and is used to adjust the distance between the fixtures;

[0030] A movable frame 4 is movably installed outside the lead screw 3. A second driving motor 5 is fixedly arranged on one side of the movable frame 4. The second driving motor 5 is used to drive the fixture and the cavity filter to rotate and adjust. A first gear 6 is fixedly installed at one end of the second driving motor 5. A second gear 7 is movably connected to one side of the first gear 6. A movable sleeve 8 is fixedly installed inside the second gear 7. A housing 9 is fixedly installed on one side of the movable sleeve 8;

[0031] A clamping block 17 is movably arranged inside the housing 9 and is used to clamp the cavity filter. When the cavity filter needs to be adjusted according to the painting angle, the second driving motor 5 is started to drive the first gear 6 and the second gear 7 to engage and drive, so that the movable sleeve 8 inside the second gear 7 rotates and adjusts with the housing 9 and the clamping block 17, thereby adjusting the cavity filter at different angles for painting treatment.

[0032] As Figure 1 and Figure 2 shown, a first driving motor 2 is fixedly arranged on one side of the base 1. One end of the lead screw 3 is fixed to the output end of the first driving motor 2. The two sides of the lead screw 3 are arranged in a clockwise and counterclockwise order respectively. The first driving motor 2 is started to drive the lead screw 3 to rotate inside the base 1. At the same time, the two sides of the lead screw 3 are arranged in a clockwise and counterclockwise order respectively, and the two groups of movable frames 4 are moved towards the middle to clamp the cavity filter.

[0033] As Figure 3 shown, the movable sleeve 8 is meshed and connected with the first gear 6 through the second gear 7. The movable sleeve 8 and the second gear 7 are integrally arranged. Through the meshing and driving between the second gear 7 and the second gear 7, the cavity filter clamped inside the clamping block 17 is rotated and adjusted.

[0034] As Figure 3 and Figure 4As shown, on the other side of the movable sleeve 8, a cylinder 10 is fixedly arranged. A piston rod 11 is movably connected inside the cylinder 10. A connecting block 12 is installed on one side of the piston rod 11. Limiting blocks 13 are fixedly installed on both sides of the connecting block 12. Movable blocks 14 are movably connected to both sides of the connecting block 12. A limiting groove 15 is formed on one side surface of the connecting block 12. When the cylinder 10 is started to push the piston rod 11 and the connecting block 12 inside, the movable blocks 14 are moved to both sides to clamp both sides of the cavity filter.

[0035] As Figure 4 and Figure 5 shown, the connecting block 12 is trapezoidally arranged. The connecting block 12 is slidably connected to the movable block 14 through the limiting blocks 13. The trapezoidal dimensions on both sides of the connecting block 12 match the internal dimensions of the movable block 14. By sliding the trapezoidally arranged connecting block 12 inside the movable block 14, the movable block 14 and the clamping block 17 are pushed to both sides, thereby adjusting the width of the cavity filter.

[0036] As Figure 4 and Figure 5 shown, sliding blocks 16 are fixedly installed on the upper and lower sides of the movable block 14. The clamping block 17 is fixed on one side of the movable block 14. The clamping block 17 is installed on the movable block 14 by means of threaded connection, which is convenient for disassembly. The setting of the sliding blocks 16 improves the stability when the movable block 14 expands and contracts inside the outer shell 9.

[0037] The working principle of this utility model: First, connect the external power supply. Then, place the cavity filter between the two groups of movable frames 4. Next, turn on the switch of the first driving motor 2 to drive the lead screw 3 to rotate. The two sides of the lead screw 3 are arranged in a clockwise and counterclockwise order respectively, and the two groups of movable frames 4 are moved towards the cavity filter in the middle for clamping. When the clamping block 17 touches the cavity filter, turn off the switch of the first driving motor 2. Then, according to the width of the cavity filter, turn on the switch of the cylinder 10 to pull the piston rod 11 and the connecting block 12 inside to expand and contract. The retracted connecting block 12 pulls the movable blocks 14 on both sides closer to the front and rear sides of the cavity filter through the limiting blocks 13. When the clamping block 17 clamps the cavity filter, turn off the switch of the cylinder 10 to clamp and fix both sides of the cavity filter. At this time, the painting treatment of the cavity filter can be started. When it is necessary to paint other angles of the cavity filter, turn on the switch of the second driving motor 5 to drive the first gear 6 and the second gear 7 to engage and transmit, so that the movable sleeve 8 inside the second gear 7 rotates and adjusts with the outer shell 9 and the clamping block 17, thereby painting the cavity filter at different angles. When the appropriate angle is adjusted, turn off the switch of the second driving motor 5. Finally, when the painting is completed, take out the cavity filter through the above steps. Finally, cut off the external power supply. Just like this, the use process of the cavity filter spraying fixture with a rotation adjustment structure is completed.

[0038] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
