Description

Technical Field

[0001] This utility model belongs to the field of blade disc structure technology, specifically relating to a grinding machine blade disc structure with a protective cover. Background Technology

[0002] A grinding machine is a grinding machine used to grind the surface of a workpiece during the processing and production of a workpiece. During the grinding process, the grinding machine needs to install a cutter head on its drive end for grinding. The existing cutter head structure is a grinding component used for grinding workpieces during the processing and production of a grinding machine, which is convenient for installation and driving grinding.

[0003] Existing cutter disc structures are directly protected by a protective cover when used on a grinding machine. However, even with the cover, debris still flies up, increasing the accumulation of abrasive particles inside the cover during grinding. This makes dust collection difficult, and prolonged accumulation can affect grinding performance. Furthermore, foreign matter can be generated on the surface of the product after grinding. Additionally, prolonged grinding can generate excessive heat in the cutter disc, hindering heat dissipation and compromising the ease of preventing splashing, uniform dust collection, and heat dissipation when the cutter disc is used on the grinding machine. Therefore, this invention proposes a grinding machine cutter disc structure with a protective cover. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding machine cutter head structure with a protective cover, so as to solve the problems mentioned in the background art. When the cutter head structure is installed on the grinding machine for processing, debris will still be raised when protected by the protective cover, and it is not easy to clean the dust. The accumulation of debris over a long period of time will affect the grinding process, and foreign objects will be generated on the surface of the product after grinding. At the same time, the cutter head will generate a lot of heat during long-term grinding, which is not easy to dissipate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding machine cutter head structure with a protective cover, comprising a cutter head structure body, the cutter head structure body including a mounting shell, the grinding cutter head being fixed inside the mounting shell by a mounting shaft and bolts, a mounting seat integrally provided at the top of the mounting shell, and internal threaded holes provided on both sides of the interior of the mounting seat; the cutter head structure body is also provided with:

[0006] A splash-proof dust collection mechanism, comprising a splash-proof protective component disposed on the front surface of the mounting housing located on the outer surface of the grinding disc, wherein a uniform dust collection component is disposed inside the splash-proof protective component, and a return air connection component is disposed at one end of the splash-proof protective component;

[0007] The reinforcement mechanism includes a screw-in adjustment assembly located inside the mounting base at the connection of two internal threaded holes, wherein the end of the screw-in adjustment assembly is provided with a reinforcement assembly located inside the internal threaded hole.

[0008] Preferably, the anti-splash protection assembly includes a metal protective cover fixedly mounted on the front surface of the mounting housing located on the outer surface of the grinding disc by screws, and a brush protective cover is fixedly mounted on the front surface of the metal protective cover by screws.

[0009] Preferably, the brush guard has an arc-shaped structure, and the rear surface of the brush guard matches the surface structure of the metal guard.

[0010] Preferably, the uniform dust collection component includes a dust collection chamber inside a metal protective cover, and a uniform air intake plate is welded and fixed to the surface of the dust collection chamber inside the metal protective cover.

[0011] Preferably, the return air connection assembly includes a dust suction hood that is sealed and fixedly installed on one side of the metal protective cover and the brush protective cover, and the dust suction hood is connected to the interior of the dust suction chamber. The end of the dust suction hood extends into the interior of the brush protective cover, and a return air pipe is fixedly installed at the tail end of the dust suction hood.

[0012] Preferably, the screw-in adjustment assembly includes an adjustment groove located inside the mounting base at the connection of two internal threaded holes. A compression cone is provided inside the adjustment groove. Two return springs are fixed at the connection between the upper surface of the compression cone and the top of the adjustment groove.

The end of the pressure plate is integrally formed with an arc-shaped surface, and the surface of the arc-shaped surface is in contact with the surface of the extrusion cone.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing an anti-splash dust collection mechanism, the metal protective cover and brush protective cover effectively prevent grinding debris from flying up during the grinding process after the main body of the blade disc structure is installed. Then, the return air pipe and dust collection cover create negative pressure inside the dust collection chamber. The debris generated on the inner surface of the metal protective cover and brush protective cover enters the dust collection chamber evenly through the uniform air inlet plate. The dust collection removes the grinding debris, reduces foreign objects on the end face of the product after grinding, and absorbs the heat generated on the surface of the grinding blade disc during the dust collection process, facilitating heat dissipation. This improves the convenience of anti-splash, uniform dust collection and heat dissipation when the main body of the blade disc structure is installed on the grinding machine.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a grinding machine cutter head structure with a protective cover, including a cutter head structure body 100, the cutter head structure body 100 including a mounting shell 101, a grinding cutter head 102 fixed inside the mounting shell 101 by a mounting shaft and bolts, a mounting seat 103 integrally provided at the top of the mounting shell 101, and internal threaded holes 104 provided on both sides of the interior of the mounting seat 103. The cutter head structure body 100 is also provided with:

[0025] The anti-splash dust collection mechanism includes an anti-splash protection component located on the front surface of the mounting housing 101 and on the outer surface of the grinding disc 102. The anti-splash protection component has a uniform dust collection component inside and a return air connection component at one end. When the main body of the disc structure 100 is fixedly installed and in use, the anti-splash dust collection device can effectively prevent grinding debris from being lifted up, increase the probability of it being sucked away by the return air pipe 1015, reduce foreign objects on the end face of the product after grinding, and facilitate heat dissipation.

[0026] In order to facilitate the removal of debris generated during grinding by the grinding disc 102, in this embodiment, preferably, the anti-splash protection component includes a metal protective cover 1011 fixedly mounted on the front surface of the mounting housing 101 on the outer surface of the grinding disc 102 by screws. A brush protective cover 1012 is fixedly mounted on the front surface of the metal protective cover 1011 by screws, and the rear surface of the brush protective cover 1012 matches the surface structure of the metal protective cover 1011. This allows the metal protective cover 1011 and the brush protective cover 1012 to prevent the debris generated during grinding by the grinding disc 102 from being lifted, thus facilitating protective use.

[0027] In order to facilitate uniform dust collection inside the metal protective cover 1011 and the brush protective cover 1012 through the uniform dust collection component, in this embodiment, preferably, the uniform dust collection component includes a dust collection chamber 1016 for collecting dust inside the metal protective cover 1011. A uniform air inlet plate 1013 is welded and fixed to the surface of the dust collection chamber 1016 inside the metal protective cover 1011. When debris is being collected inside the metal protective cover 1011 and the brush protective cover 1012, the uniform air inlet plate 1013 can again uniformly draw the debris inside into the dust collection chamber 1016 for dust collection.

[0028] To facilitate the installation and cleaning of external vacuum equipment via the return air connection assembly, in this embodiment, preferably, the return air connection assembly includes a vacuum hood 1014 that is sealed and fixedly installed on one side of the metal protective cover 1011 and the brush protective cover 1012. The vacuum hood 1014 is connected to the interior of the vacuum chamber 1016, and the end of the vacuum hood 1014 extends into the interior of the brush protective cover 1012. A return air pipe 1015 is fixedly installed at the tail end of the vacuum hood 1014. A vacuum equipment can be installed at the tail end of the return air pipe 1015 to generate negative pressure inside the vacuum chamber 1016 for uniform vacuuming, while also facilitating heat dissipation.

[0029] The reinforcement mechanism includes a screw-in adjustment component located inside the mounting base 103 at the connection of the two internal threaded holes 104. The end of the screw-in adjustment component is located inside the internal threaded hole 104 and is reinforced. After the cutter head structure body 100 is fixedly installed, the reinforcement mechanism can further strengthen the fixing bolts and mounting shell 101, making the reinforcement installation more stable.

[0030] To facilitate the pressing, moving, and fixing of the pressure plate 1046 via the screw-in adjustment assembly, in this embodiment, preferably, the screw-in adjustment assembly includes an adjustment groove 1042 located inside the mounting base 103 at the connection of two internal threaded holes 104. An extrusion cone 1043 is disposed inside the adjustment groove 1042. Two return springs 1047 are fixed at the connection between the upper surface of the extrusion cone 1043 and the top end of the adjustment groove 1042. An adjustment bolt 1041 is threadedly connected to the top end of the mounting base 103, and the bottom end of the adjustment bolt 1041 is in pressing contact with the middle position of the upper surface of the extrusion cone 1043. The adjustment bolt 1041 can be rotated to press and move the extrusion cone 1043, facilitating the movement of the extrusion cone 1043 to move and press the pressure plate 1046 for reinforcement.

[0031] To facilitate reinforcement installation using the reinforcement components, in this embodiment, preferably, the reinforcement components include limiting and moving grooves 1045 formed on both sides of the bottom end of the adjusting groove 1042. A pressure plate 1046 is limited inside the limiting and moving groove 1045. An arc-shaped surface 1044 is integrally formed at the end of the pressure plate 1046, and the surface of the arc-shaped surface 1044 is in contact with the surface of the extrusion cone 1043. When the extrusion cone 1043 moves down, it can press and move the surface of the arc-shaped surface 1044 against the pressure plate 1046, which facilitates the extrusion and moving reinforcement installation.

[0032] The working principle and usage process of this utility model: When using this grinding machine cutter head structure with a protective cover, firstly, the rotating shaft installed inside the grinding cutter head 102 is fixedly installed to the end of the motor output shaft on the grinding machine. Then, the mounting base 103 connected to the top of the mounting shell 101 is brought into contact with the installation position on the grinding machine. The fixing bolt is rotated into the internal thread hole 104 for rotation and fixing, thereby facilitating the fixed installation of the cutter head structure body 100 and driving the grinding cutter head 102 to perform grinding processing through the motor.

[0033] Then, before use after installation, the metal protective cover 1011 and the brush protective cover 1012 are fixedly installed on the surface of the mounting shell 101 on the outer surface of the grinding disc 102. During the grinding process of the grinding disc 102, the metal protective cover 1011 and the brush protective cover 1012 effectively prevent grinding debris from flying up. At the same time, when the return air pipe 1015 is connected to the external vacuum cleaner to generate negative pressure suction, the vacuum chamber 101 is then suctioned through the return air pipe 1015 and the vacuum cover 1014. The internal negative pressure of 6 causes the debris generated on the inner surfaces of the metal protective cover 1011 and the brush protective cover 1012 to enter the dust collection chamber 1016 evenly through the uniform air inlet plate 1013. The dust collection process removes the grinding debris and reduces foreign objects on the end face of the product after grinding. At the same time, the heat generated on the surface of the grinding disc 102 is also removed during the dust collection process, which facilitates heat dissipation and improves the convenience of anti-splash uniform dust collection and heat dissipation when the disc structure body 100 is installed on the grinding machine.

[0034] Finally, after the main body 100 of the cutter head structure is installed, the adjusting bolt 1041 is inserted through the connection hole at the installation location and embedded into the interior of the mounting base 103. As the adjusting bolt 1041 moves downward, it presses against the surface of the extrusion cone 1043, causing the extrusion cone 1043 to move downward. When the extrusion cone 1043 moves downward, it contacts the surface of the arc-shaped surface 1044, pressing and moving the pressure plate 1046 inside the limiting movement groove 1045 until the pressure plate 1046 is pressed and clamped against the surface of the fixing bolt for reinforcement and installation. This facilitates reinforcement and installation again after the fixing bolt is rotated and installed. When subjected to force and vibration, the mounting shell 101 is less likely to loosen, thus improving the reinforcement and fixation of the mounting shell 101 when the main body 100 of the cutter head structure is installed on the grinding machine.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
