Description

Technical Field

[0001] The utility model relates to the technical field of gear processing equipment, in particular to a device with the function of removing dust from the surface of gear parts after shot blasting. Background Art

[0002] In the field of mechanics, shot blasting refers to a cold treatment process, which is divided into shot blasting and shot blasting. Shot blasting, as the name suggests, is to remove impurities such as surface oxide and improve the appearance quality. Shot blasting is to use a high-speed moving projectile (60-110m / s) to continuously impact the surface of the workpiece to be strengthened, forcing the target surface and surface layer (0.10-0.85mm) to undergo the following changes during the cyclic deformation process: (1) The microstructure is modified; (2) The non-uniform plastic deformation of the outer surface introduces residual compressive stress, and the inner surface generates residual tensile stress; (3) The outer surface roughness changes (Ra Rz). After shot blasting, the workpiece can improve its fatigue fracture resistance, prevent fatigue failure, plastic deformation and brittle fracture, and also improve the fatigue life of the workpiece. Therefore, in the processing of gear parts, it is also necessary to set up a shot blasting process to improve the fatigue fracture resistance and fatigue life of gear parts. Conventional shot blasting equipment mostly only has a shot blasting function. After the shot blasting of gear parts, dust or foreign matter will adhere to the surface, which requires manual cleaning. This will inevitably increase the workload of workers and prolong the unloading operation time of the gear parts, resulting in long equipment downtime, thus restricting the shot blasting efficiency of gear parts. To this end, the utility model proposes a device that can remove dust from the surface of gear parts after shot blasting, in order to solve the above technical problems. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects existing in the prior art and provide a device with the function of clearing dust from the surface of gear parts after shot blasting. A purge and dust cleaning component for blowing high-pressure compressed air into the interior of the box is fixedly provided on the side wall of the box, so that after the shot blasting of the gear parts placed inside the box is completed, high-pressure compressed air is blown to the gears inside the box through the purge and dust cleaning component, so that dust and other impurities attached to the surface of the gears are blown away, and then when the gear parts are unloaded after the shot blasting is completed, there is no need to manually clean the gear surface, which effectively reduces the labor of the operator and helps to shorten the unloading time of the gears, thereby greatly improving the shot blasting efficiency of the gear parts; the overall structural design is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0004] To achieve the above-mentioned purpose, the technical solution of the present utility model is to design a device with the function of removing dust from the surface of gear parts after shot blasting, including a box body and a dust collector. The front side of the box body is provided with a door body, and a shot blasting emission assembly is provided on the side wall of the box body. The emission end of the shot blasting emission assembly faces the inner side of the box body, and a number of blowing and cleaning assemblies are also fixedly connected to the side wall of the box body. The air inlet ends of several of the blowing and cleaning assemblies are externally connected to high-pressure compressed air, and the air outlet ends of several of the blowing and cleaning assemblies face the inner side of the box body, and the air outlet ends of several of the blowing and cleaning assemblies are provided with a cover that can be flipped open, and the air inlet end of the dust collector is docked with the dust removal port on the side wall of the box body.

[0005] The utility model relates to a device with the function of cleaning dust on the surface of gear parts after shot blasting. A purge and dust cleaning component for blowing high-pressure compressed air into the interior of the box is fixedly provided on the side wall of the box. After the shot blasting of the gear parts placed inside the box is completed, high-pressure compressed air is blown to the gears inside the box through the purge and dust cleaning component, so that dust and other impurities attached to the gear surface are blown away. Furthermore, when the gear parts are unloaded after the shot blasting, there is no need to manually clean the gear surface, which effectively reduces the labor of the operator and helps to shorten the unloading time of the gear, thereby greatly improving the shot blasting efficiency of the gear parts. The overall structural design is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0006] The preferred technical solution is that the purge and dust cleaning assembly includes a main body, which is fixedly mounted on the side wall of the casing. The upper edge of the cover plate is hingedly connected to the upper edge of the main body located at the inner end of the casing via a connector. The end of the main body located outside the casing is provided with a connecting head for connecting to an external high-pressure compressed air pipeline. The purge and dust cleaning assembly has an ingenious and reasonable structural design. During shot blasting, no high-pressure compressed air is introduced into the main body. The cover plate droops due to its own gravity and is pressed against one end of the main body located inside the casing, thereby preventing sand and powder ejected from the launch end of the shot blasting assembly from entering the main body and preventing a large amount of sand and powder from being lost.

[0007] A further preferred technical solution is that the connecting member is a hinge or a pin assembly. The connecting member has a simple structural design, ensuring that the cover plate can be smoothly hingedly installed on the end of the main body of the purge and dust cleaning assembly located inside the box.

[0008] A further preferred technical solution also includes a conical air deflector, wherein the small-diameter end of the conical air deflector is coaxially docked and fixedly connected to the end of the main body located inside the box, and the large-diameter end of the conical air deflector faces the inside of the box. The upper side of the conical air deflector has a fan-shaped notch, and the cover plate is located correspondingly in the fan-shaped notch of the conical air deflector. The air outlet end of the main body of the purge and dust cleaning assembly is provided with a conical air deflector, so that the high-pressure compressed air blown out of the main body is guided by the conical air deflector and better concentratedly blown onto the gears located inside the box, helping to improve the cleaning efficiency of dust attached to the gear surfaces.

[0009] A further preferred technical solution is that the main body, cover plate, conical air guide cover, and connector are all made of a wear-resistant alloy. The components of the dust cleaning assembly that come into contact with the sand powder during shot blasting inside the box are all made of a wear-resistant alloy, thereby preventing rapid wear of the dust cleaning assembly components by the high-speed sand powder, thereby increasing the maintenance cycle and service life of the device.

[0010] A further preferred technical solution is that the shot blasting assembly is mounted on one of the left or right side walls of the box, and the plurality of purge and dust cleaning assemblies are mounted on the other of the left or right side walls of the box. The shot blasting assembly and the purge and dust cleaning assemblies are mounted separately on the left and right side walls of the box, ensuring ease of installation and maintenance of the two on the box.

[0011] A further preferred technical solution is that a guide slot is provided in the middle of the top of the box body along the front-to-back direction, a hook is provided inside the box body for hanging the parts placement rack, a suspension rod fixed to the upper end of the suspension rod is movably connected to the inside of the guide slot, and the upper end of the suspension rod is rotatably connected to the lower end of the guide vertical rod through a connecting sleeve, and the upper end of the guide vertical rod is slidably installed in the guide slot at the bottom of the horizontal longitudinal beam. When loading or unloading, the driving mechanism on the horizontal longitudinal beam drives the guide vertical rod and the suspension hook to move forward and backward along the guide slot on the horizontal longitudinal beam;

[0012] The boom is fixed with a driven gear located above the top of the box. The top of the box is fixed with a drive motor. The output shaft of the drive motor is fixed with a driving gear. During shot blasting, the driven gear and the driving gear mesh with each other. This ensures that the parts rack loaded with gears can be quickly loaded or unloaded within the box, which helps improve the efficiency of gear shot blasting. During shot blasting or cleaning and dust removal, the drive motor always drives the parts rack loaded with gears in a rotating state, which helps improve the efficiency of gear shot blasting and dust cleaning.

[0013] A further preferred technical solution is that there are two sets of purge and dust cleaning components, which are arranged at intervals on the left or right wall of the box body. During shot blasting, the high-pressure air areas blown out by the air outlet ends of the two sets of purge and dust cleaning components correspond to covering the entire part placement rack suspended on the hook. The high-pressure air areas blown out by the air outlet ends of the two sets of purge and dust cleaning components correspond to covering the entire part placement rack suspended on the hook, thereby ensuring that the outer surfaces of the gears loaded on the part placement rack can be efficiently blown and cleaned, which helps to significantly improve the purge and dust cleaning efficiency of the gears after shot blasting.

[0014] A further preferred technical solution is that a "7"-shaped bracket is fixedly provided on the top of the box body, and the driving motor is fixedly provided on the "7"-shaped bracket.

[0015] A further preferred technical solution is that the dust removal port and the dust collector are both arranged on the top of the box.

[0016] The advantages and beneficial effects of the utility model are:

[0017] 1. The utility model provides a device with the function of removing dust from the surface of gear parts after shot blasting. A purge and dust cleaning component for blowing high-pressure compressed air into the interior of the box is fixedly provided on the side wall of the box. After the shot blasting of the gear parts placed inside the box is completed, the purge and dust cleaning component blows high-pressure compressed air to the gears inside the box, so that dust and other impurities attached to the gear surfaces are blown away. When the gear parts are unloaded after the shot blasting, there is no need to manually clean the gear surfaces, which effectively reduces the labor of the operator and helps to shorten the unloading time of the gears, thereby greatly improving the shot blasting efficiency of the gear parts. The overall structural design is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0018] 2. The structure design of the purge and dust cleaning component is ingenious and reasonable. During shot blasting, no high-pressure compressed air is introduced into the main body. The cover plate hangs down by its own gravity and is pressed against one side of the main body inside the box, thereby preventing the sand and powder ejected from the emission end of the shot blasting emission component from entering the main body and avoiding a large amount of sand and powder loss.

[0019] 3. The connecting piece is a hinge or a pin assembly. The connecting piece has a simple structural design, ensuring that the cover plate can be smoothly hinged and installed on the end of the main body of the purge and dust cleaning assembly located inside the box.

[0020] 4. A conical air guide cover is provided at the air outlet end of the main body of the purge and dust cleaning component, so that the high-pressure compressed air blown out from the main body can be better concentrated on the gears located inside the box after being guided by the conical air guide cover, which helps to improve the cleaning efficiency of the dust attached to the gear surface.

[0021] 5. The main body, cover, conical guide cover, and connectors are all made of wear-resistant alloy. The dust cleaning component and the parts that come into contact with the sand powder during shot blasting inside the box are all made of wear-resistant alloy. This prevents the high-speed sand powder from causing rapid wear on the dust cleaning component parts that come into contact with the sand powder, helping to increase the maintenance cycle and service life of the device.

[0022] 6. The shot blasting component and the purge and dust cleaning component are separately arranged on the left and right walls of the box, ensuring the convenience of both installation or maintenance on the box.

[0023] 7. The high-pressure air area blown out by the air outlet of the two sets of blowing and cleaning components covers the entire part placement rack hung on the hook, thereby ensuring that the outer surface of the gear loaded on the part placement rack can be efficiently blown and cleaned, which helps to greatly improve the blowing and cleaning efficiency of the gear after shot blasting.
