Description

Technical Field

[0001] The utility model relates to the technical field of protection fixtures, and more specifically, to a spraying protection fixture for a connecting rotating shaft iron. Background Technique

[0002] In the mechanical field, a rotating shaft generally refers to a shaft rod that can rotate, and a connecting rotating shaft iron is an iron part used to connect a rotating shaft with other components. In some large-scale mechanical equipment, there may be special iron connectors to connect the rotating shaft for power transmission with the rotating shaft of a working component to achieve energy transfer and work progress. Or in some small mechanical devices, similar iron connectors play a role in fixing the position of the rotating shaft and ensuring its stable rotation. In order to extend the service life of the connecting rotating shaft iron, it is usually necessary to spray it to increase its surface hardness and reduce friction and wear. During the spraying process, in order to make the spraying of the connecting rotating shaft iron more accurate, fixtures are usually used to fix it to ensure the accuracy of spraying.

[0003] However, the existing spraying protection fixtures for connecting rotating shaft irons have the following problems when in use:

[0004] When spraying the connecting rotating shaft iron, usually only the rotating shaft iron is clamped, and the rotating shaft iron cannot be protected. When spraying, the entire rotating shaft iron is sprayed as a whole, and the effect of spraying only the specified part without spraying other parts cannot be achieved, which is likely to cause waste of paint and easily lead to the accidental spraying of areas that do not need to be sprayed, and the spraying is not precise enough.

[0005] The utility model can play a role in spraying the specified area without accidentally spraying other areas when spraying the rotating shaft iron, reducing paint waste and making the spraying more accurate. Content of the Utility Model

[0006] The purpose of the utility model is to solve the technical problems proposed in the above background technique, and provide a spraying protection fixture for a connecting rotating shaft iron.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a spraying protection fixture for a connecting rotating shaft iron, including: a rotating shaft iron body, a clamping mechanism is arranged around the surface of the rotating shaft iron body, rotating mechanisms are fixedly installed at equal distances at the front and rear ends of the clamping mechanism, a protective sleeve is fixedly installed on the outer side surface of the rotating mechanism, the clamping mechanism is composed of a connecting plate, a baffle plate, and a rotating shaft I. The connecting plate is movably installed above the rotating shaft iron body, baffle plates are movably installed on the left and right sides of the bottom of the connecting plate, rotating shafts I are rotatably installed on the left and right sides of the bottom of the connecting plate, and the baffle plates are fixedly installed at the bottom of the rotating shafts I;

[0008] The rotating mechanism is composed of a fixed block, a connecting arm, a second rotating shaft, and a fixing plate. The fixed block is fixedly installed above the outer end face of the baffle. Connecting arms are rotatably installed at both the left and right ends of the fixed block. The second rotating shafts are embedded and installed in the middle of the bottom of the connecting arm and the fixed block respectively. A fixing plate is fixedly installed above the inner side surface between the two connecting arms. The protective sleeve is fixedly installed on the outer end face of the fixing plate.

[0009] Further preferred solution: Raised columns are fixedly connected at equal distances at the front and rear ends of the rotating shaft iron body, and the raised columns are all movably connected to the baffle.

[0010] Further preferred solution: A number of limiting holes are provided in the middle of the baffle. The structure, size, and quantity of the limiting holes are the same as those of the raised columns. The raised columns pass through the limiting holes and are connected to the baffle. A number of jacks are provided above the limiting holes, and the jacks are located behind the fixing plate.

[0011] Further preferred solution: A plug rod is fixedly installed in the middle of the rear end of the fixing plate. The plug rod is provided in a matching manner with the jack, and the plug rod is embedded and connected inside the jack.

[0012] Further preferred solution: A cover plate is movably installed on the front of the protective sleeve. An embedding block is fixedly installed at the rear end of the cover plate, and a connecting strip is fixedly installed at the upper end of the cover plate.

[0013] Further preferred solution: The embedding block is embedded inside the protective sleeve, and the other end of the connecting strip is fixedly connected to the upper end of the protective sleeve.

[0014] Beneficial effects:

[0015] 1. By providing a connecting plate, a baffle, a rotating shaft, and limiting holes, the connecting plate provides an installation basis for the baffle and the rotating shaft, enabling them to be combined together in an orderly manner. The baffle rotates flexibly through the rotating shaft, and the limiting holes cooperate with the raised columns on the connecting rotating shaft iron. When the baffle rotates around the rotating shaft to a suitable position, the raised columns pass through the limiting holes, achieving the accurate connection and positioning of the baffle and the connecting rotating shaft iron, improving the versatility of the fixture. During the spraying process, the connecting rotating shaft iron can be firmly clamped, providing a reliable basis for subsequent precise spraying.

[0016] 2. By providing a plug rod and a jack, when the connecting arm does not need to be lowered, the plug rod at the rear end of the fixing plate can accurately be embedded into the corresponding jack on the baffle, enabling the fixing plate to be more firmly connected to the baffle, thereby fixing the connecting arm in the current position and preventing it from shaking and moving randomly.

[0017] 3. By providing a protective sleeve, a cover plate, an embedded block, and a connecting strip, a more refined and flexible operation method is provided for the spraying protection of the connecting rotating shaft iron. The protective sleeve can block the protruding columns that do not need to be sprayed, ensuring the accuracy and consistency of spraying. For the area of the protruding columns that need to be sprayed, the cover plate can protect the inside of the protective sleeve to prevent the inside of the protective sleeve from being accidentally sprayed. The embedded block and the connecting strip can enhance the connection stability between the cover plate and the protective sleeve and make the cover plate not easy to be lost when it is opened;

[0018] 4. In summary, for this kind of spraying protection fixture for the connecting rotating shaft iron, through the structures such as the baffle and the protective sleeve, comprehensive and accurate spraying protection for the connecting rotating shaft iron is realized. The baffle is movably connected to the connecting plate through a rotating shaft, and with the cooperation of the limiting hole and the protruding column, a firm clamping is provided to ensure that the rotating shaft iron does not displace during the spraying process. Secondly, the protective sleeve is connected through a rotating mechanism, and with the cooperation of the second rotating shaft and the connecting arm, the protective position can be adjusted to effectively block the areas that do not need to be sprayed. While improving the spraying efficiency and quality, its applicability and operation convenience are greatly enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Please refer to Figures 1-5, in the embodiment of the present utility model, a spraying protection fixture for a connecting rotating shaft iron includes: a rotating shaft iron body 1, a clamping mechanism is arranged around the surface of the rotating shaft iron body 1, rotating mechanisms are fixedly arranged at equal distances at the front and rear ends of the clamping mechanism, a protective sleeve 4 is fixedly installed on the outer side surface of the rotating mechanism, the clamping mechanism is composed of a connecting plate 2, a baffle 201, and a rotating shaft 202. The connecting plate 2 is movably installed above the rotating shaft iron body 1, baffles 201 are movably installed on the left and right sides of the bottom of the connecting plate 2, rotating shafts 202 are rotatably installed on the left and right sides of the bottom of the connecting plate 2, and the baffle 201 is fixedly installed at the bottom of the rotating shaft 202; the rotating mechanism is composed of a fixed block 3, a connecting arm 301, a rotating shaft 302, and a fixing plate 303. The fixed block 3 is fixedly installed above the outer end surface of the baffle 201, connecting arms 301 are rotatably installed at both the left and right ends of the fixed block 3, rotating shafts 302 are embedded and installed at the middle parts of the connecting arm 301 and the bottom of the fixed block 3, a fixing plate 303 is fixedly installed above the inner side surface between the two connecting arms 301, the protective sleeve 4 is fixedly installed on the outer end surface of the fixing plate 303, convex columns 101 are fixedly connected at equal distances at the front and rear ends of the rotating shaft iron body 1, the convex columns 101 are all movably connected with the baffle 201, a plurality of limiting holes 203 are opened in the middle of the baffle 201, the structure, size, and quantity of the limiting holes 203 are the same as those of the convex columns 101, the convex columns 101 pass through the limiting holes 203 and are connected with the baffle 201. When using the protection fixture to protect the rotating shaft iron body 1 during spraying, first, the connecting plate 2 is located above the rotating shaft iron body 1, providing an installation basis for the baffle 201 and the rotating shaft 202, playing a role in connection and support. Through the rotating shaft 202, the baffle 201 can rotate towards the rotating shaft iron body 1 to surround and clamp the rotating shaft iron body 1. Secondly, the convex columns 101 cooperate with the limiting holes 203 on the baffle 201 to play a role in positioning and fixing the baffle 201, ensuring that the baffle 201 remains stable, thereby improving the clamping and protection effects. Subsequently, by fixedly installing the fixed block 3 on the baffle 201, the fixed block 3 provides an installation position for the connecting arm 301 and the rotating shaft 302. The connecting arm 301 is connected with the fixed block 3 through the rotating shaft 302 and can rotate, thereby adjusting the position of the protective sleeve 4. During spraying, first, the baffle 201 is lowered so that the convex columns 101 pass through the limiting holes 203. Then, the connecting arm 301 is lowered so that the protective sleeve 4 can be nested on the surface of the convex columns 101 to protect them. According to the spraying requirements, it is possible to freely choose whether to lower the protective sleeve 4 above the convex columns 101 for protection. The convex columns 101 protected by the protective sleeve 4 will not be affected by spraying, preventing the paint from being sprayed onto the areas that do not need to be sprayed.

[0027] In the embodiment of the present utility model, a plurality of jacks 204 are provided above the limit hole 203. The jacks 204 are located behind the fixing plate 303. A plug rod 304 is fixedly installed in the middle of the rear end of the fixing plate 303. The plug rod 304 is arranged in a matching manner with the jacks 204. The plug rod 304 is embedded and connected inside the jacks 204. When spraying is not carried out, the connecting arm 301 is lifted upward. The fixing plate 303 is located above the fixing block 3, and the plug rod 304 is embedded inside the jacks 204, realizing the further connection and fixation between the fixing plate 303 and the baffle 201, enhancing the stability of the position of the fixing plate 303, and making it not easy to shake when it is not in the working state. When it is necessary to use the protective sleeve 4 at the current position for protection, only need to pull out the plug rod 304 from the jacks 204 and lower the fixing plate 303.

[0028] In the embodiment of the present utility model, a cover plate 401 is movably installed on the front surface of the protective sleeve 4. An embedding block 402 is fixedly installed at the rear end of the cover plate 401. A connecting strip 403 is fixedly installed at the upper end of the cover plate 401. The embedding block 402 is embedded inside the protective sleeve 4. The other end of the connecting strip 403 is fixedly connected to the upper end of the protective sleeve 4. When it is necessary to use the protective sleeve 4 to protect the convex column 101, pull out the cover plate 401 from the protective sleeve 4, so that the embedding block 402 is pulled out from the protective sleeve 4. Since both ends of the connecting strip 403 are respectively fixed on the cover plate 401 and the protective sleeve 4, after the cover plate 401 is pulled out, it is restricted by the connecting strip 403 and will not fall and be lost randomly. After the cover plate 401 is pulled out, nest the protective sleeve 4 on the surface of the convex column 101 to protect it. And the inner wall of the protective sleeve 4 fits with the convex column 101 and can be stably nested on the surface of the convex column 101. After the protective sleeve 4 is not needed, pull out the protective sleeve 4 from the convex column 101 and insert the embedding block 402 back into the protective sleeve 4, so that the cover plate 401 can be stably combined with the protective sleeve 4, and it can also ensure that the inside of the protective sleeve 4 is not affected by spraying. The cover plate 401 can block the spraying paint from entering the inside of the protective sleeve 4.

[0029] Working principle: When performing the spraying operation on the rotating shaft iron, first place the rotating shaft iron body 1 in a suitable position, and the clamping mechanism starts to function. The connecting plate 2 is located above the rotating shaft iron body 1. By rotating the first rotating shafts 202 installed on both sides of the bottom of the connecting plate 2, the baffle plates 201 rotate around the first rotating shafts 202 until the limiting holes 203 on the baffle plates 203 pass through the protruding columns 101 at the front and rear ends of the rotating shaft iron body 1, thereby realizing the preliminary clamping and fixing of the rotating shaft iron body 1. Then, the rotating mechanism is adjusted to pull out the insertion rod 304 from the insertion hole 204. The connecting arms 301 at the left and right ends of the fixed block 3 rotate around the second rotating shaft 302, driving the fixing plate 303 and the protective sleeve 4 installed thereon to move to the position of the protruding column 101. The cover plate 401 is pulled out from the protective sleeve 4, and then the protective sleeve 4 is nested on the surface of the protruding column 101 to protect it, ensuring that the protective sleeve 4 can accurately cover the areas that do not need to be sprayed.
