[0014] Beneficial effects

[0015] This invention provides an easily adjustable vacuum coating processing fixture. Compared with the prior art, it has the following advantages:

[0016] (1) When the main body needs to be disassembled, the electric push rod is turned on, and the electric push rod drives the inclined ring to move downward. At this time, the inclined slide rod will drive the insert block to move outward under the action of the spring force, so that the insert block is removed from the inner wall of the placement cylinder. At this time, the placement cylinder and the main body can be removed from the rotating cylinder, which makes it convenient to clean and maintain the main body. When the main body needs to be installed, first align the snap strip on the placement cylinder with the snap groove on the rotating cylinder, and then insert the placement cylinder into the bottom of the inner wall of the rotating cylinder. At this time, the insertion hole on the placement cylinder is aligned with the insert block. Then turn on the two electric push rods, and the two electric push rods drive the inclined ring to rise. During the rise of the inclined ring, the inclined slide rod will be squeezed. After the inclined slide rod is squeezed, it drives the insert block to be inserted into the insertion hole on the placement cylinder, thus completing the fixation of the placement cylinder. The main body can be installed quickly. The installation and disassembly components can quickly install and disassemble the main body, which makes it convenient to clean and maintain the main body.

[0017] (2) When the workpiece to be vacuum coated needs to be rotated, and the workpiece is coated from different angles, the motor can be turned on. The motor drives the gear to rotate, and the gear drives the outer gear ring to rotate. The outer gear ring then drives the rotating ring and the main body above to rotate, so that the workpiece on the main body can rotate. This allows the angle of the workpiece to be adjusted, so that the coating material can be evenly distributed on the surface of the workpiece, thereby improving the quality of the workpiece coating.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 The first embodiment is shown: an easily adjustable vacuum coating processing fixture, including a base 1, a rotating component 3 is provided at the top of the base 1, a mounting and dismounting component 4 is provided at the top of the rotating component 3, a main body 5 is provided at the top of the mounting and dismounting component 4, the main body 5 may have a cavity inside, and a set of adsorption holes is provided at the top. When the main body 5 is connected to an air compressor, a negative pressure can be generated at the top of the main body 5, thereby adsorbing and fixing the workpiece.

[0028] The rotating assembly 3 includes a rotating ring 31, which is rotatably mounted on the top of the base 1, and an outer toothed ring 32 is fixedly sleeved on the outer wall of the rotating ring 31.

[0029] The assembly 4 includes a rotating cylinder 41, which is fixedly connected to a rotating ring 31. A placement cylinder 46 is inserted into the inner wall of the rotating cylinder 41 and is fixedly connected to the main body 5. Four L-shaped plates 42 are fixedly installed on the outer wall of the rotating cylinder 41. A slanted slide rod 43 slides through the outer wall of each of the four L-shaped plates 42. An insert block 45 is fixedly installed at the output end of each of the four slanted slide rods 43. A spring 44 is sleeved on the outer wall of each of the four slanted slide rods 43. Under the action of the spring force of the spring 44, the insert block 45 can be moved.

[0030] One end of the outer wall of each of the four insert blocks 45 penetrates the outer wall of the rotating cylinder 41. The outer wall of the placement cylinder 46 has four insertion holes. The four insert blocks 45 are matched with the four insertion holes respectively. One end of each of the four springs 44 is fixedly connected to the outer wall of each of the four L-shaped plates 42. The other end of each of the four springs 44 is fixedly connected to the outer wall of each of the four insert blocks 45. The insert blocks 45 can be inserted into the insertion holes, thereby completing the fixation of the placement cylinder 46.

[0031] Two snap-fit ​​grooves 48 are provided at the top of the rotating cylinder 41. Two snap-fit ​​strips 47 are fixedly installed on the outer wall of the placement cylinder 46. The two snap-fit ​​strips 47 are respectively matched with the two snap-fit ​​grooves 48. When the snap-fit ​​strips 47 are inserted into the snap-fit ​​grooves 48, the insertion block 45 can be aligned with the insertion hole, making it convenient for the insertion block 45 to be inserted into the insertion hole. At the same time, the snap-fit ​​strips 47 inserted into the inner wall of the snap-fit ​​grooves 48 can also improve the stability of the placement cylinder 46 inside the rotating cylinder 41.

[0032] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that two electric push rods 49 are fixedly installed at the top of the base 1. An inclined ring 410 is fixedly installed at the output end of the two electric push rods 49. The inner wall of the inclined ring 410 and four inclined slide rods 43 are fitted together. The electric push rods 49 can drive the inclined ring 410 to rise and fall. When the inclined ring 410 rises, it can squeeze the inclined slide rods 43, thereby driving the inclined slide rods 43 to move. At the same time, when the inclined slide rods 43 rotate, the inclined ring 410 can continuously squeeze the inclined slide rods 43. When the inclined ring 410 falls, the inclined slide rods 43 are not squeezed by the inclined ring 410.

[0033] A motor 33 is fixedly installed at the bottom of the base 1. The output end of the motor 33 passes through the top of the base 1 and is fixedly installed with a gear 35. The gear 35 meshes with the external gear ring 32. The motor 33 can drive the gear 35 to rotate, thereby driving the external gear ring 32 to rotate.

[0034] A circular groove 7 is provided through the bottom end of the base 1. A rotary joint 2 is fixedly connected to the bottom end of the main body 5. An air inlet pipe 6 is fixedly connected to the bottom of the rotary joint 2. The circular groove 7 allows the rotary joint 2 to be fixedly connected to the bottom end of the main body 5. The rotary joint 2 is existing technology and will not affect the rotation of the main body 5, and can always be connected to the main body 5.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, first connect the air compressor's air pipe to the air inlet pipe 6. Then, place the workpiece to be vacuum coated on the top of the main body 5. A negative pressure is generated at the top of the main body 5 to adsorb the workpiece, fixing it in place. Coating can then be applied to the workpiece. When the workpiece needs to be rotated to be coated from different angles, the motor 33 can be turned on. The motor 33 drives the gear 35 to rotate, which in turn drives the outer gear ring 32 to rotate. The outer gear ring 32 then drives the rotating ring 31 and the main body 5 above to rotate, allowing the workpiece on the main body 5 to rotate. This allows the angle of the workpiece to be adjusted, ensuring that the coating material is evenly distributed on the workpiece surface, thus improving the coating quality. When the main body 5 needs to be disassembled, activate the two electric push rods 49. The electric push rods 49 drive the inclined ring 410 downwards. At this time, the inclined slide rod 43 will be driven by the spring force of the spring 44. The insert 45 moves outward, removing it from the inner wall of the placement cylinder 46. This allows the placement cylinder 46 and the main body 5 to be removed from the rotating cylinder 41, facilitating cleaning and maintenance of the main body 5. When the main body 5 needs to be installed, first align the snap-fit ​​strip 47 on the placement cylinder 46 with the snap-fit ​​groove 48 on the rotating cylinder 41. Then, insert the placement cylinder 46 into the bottom of the inner wall of the rotating cylinder 41. At this point, the insertion hole on the placement cylinder 46 is aligned with the insert 45. Then, activate the two electric push rods 49. The two electric push rods 49 drive the inclined ring 410 upward. During the upward movement of the inclined ring 410, it will press against the inclined slide rod 43. After being pressed, the inclined slide rod 43 drives the insert 45 to insert into the insertion hole on the placement cylinder 46, thus fixing the placement cylinder 46. This allows for quick installation of the main body 5. The installation and removal assembly 4 allows for quick installation and removal of the main body 5, facilitating cleaning and maintenance.
