Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile processing, specifically to a grinding device. Background Technology

[0002] Whether sawing, shearing, or other cutting methods are used, aluminum profiles will inevitably produce sharp burrs, flash, and acute angles at their ends. These edges are extremely sharp, like knives, and can easily cut workers' hands during subsequent handling, installation, and operation. Grinding is the most direct and effective method to blunt these dangerous sharp edges, creating a smooth transition and fundamentally eliminating safety hazards, thus complying with safety production regulations.

[0003] Currently, there are two common methods for grinding the ends of aluminum profiles: manual grinding and semi-automatic grinding equipment. Manual grinding involves a person holding the grinding machine and grinding the ends of the aluminum profile. The grinding machine can use a grinding disc or a flap wheel. Semi-automatic grinding equipment can use a rotating cutting disc or a rotating flap wheel. When using a cutting disc, the aluminum profile needs to be precisely positioned so that the cutting disc can accurately remove burrs from the ends. When using a flap wheel, there are no strict positioning requirements for the aluminum profile; it is only necessary for the end of the aluminum profile to contact the flap wheel. Compared to cutting discs, the operational requirements are relatively lower, and the impact on the precision of the aluminum profile is smaller. However, regardless of whether semi-automatic equipment uses a cutting disc or a flap wheel, it can generally only grind the end of one aluminum profile at a time, requiring the replacement of the profile after grinding, resulting in low efficiency. Therefore, a grinding device needs to be designed. Utility Model Content

[0004] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem of low efficiency in existing aluminum profile grinding equipment.

[0005] To achieve the above objectives, this utility model provides a grinding device, comprising: a worktable through which a plurality of parallel first strip-shaped grooves are provided; a mounting top frame mounted on the worktable; a plurality of vertical positioning plates spaced apart along the length of the first strip-shaped grooves and each mounted detachably at the first strip-shaped groove; a plurality of pressing mechanisms detachably mounted on the mounting top frame and corresponding one-to-one with the plurality of positioning plates and adjustable along the length of the first strip-shaped grooves; a housing fixedly mounted on the side of the worktable and close to the mounting top frame; and a grinding unit mounted inside the housing. The housing is provided with a window portion corresponding to the first strip-shaped through groove, and the polishing unit includes a sandpaper flap wheel that can slide and rotate along the length direction of the first strip-shaped through groove.

[0006] Preferably, the top of the mounting bracket is provided with at least one second strip-shaped through groove, and the pressing mechanism includes a vertical pressing cylinder, a pressure plate connected to the moving end of the pressing cylinder, a connecting frame fixedly connected to the pressing cylinder, a plurality of first mounting bolts passing through the second strip-shaped through groove and assembled on the pressure plate, and a button box assembled on the connecting frame.

[0007] Preferably, the positioning plate has several vertical mounting holes, and each mounting hole is fitted with a second mounting bolt that slides through the first strip groove and is assembled on the worktable.

[0008] Preferably, a washer is fitted on the lower end of a plurality of second mounting bolts, and the upper surface of the washer is provided with anti-slip texture that contacts the lower surface of the workbench.

[0009] Preferably, the grinding unit further includes a horizontal moving mechanism assembled inside the housing and whose moving end moves in a direction parallel to the length direction of the first strip groove, a motor assembled on the moving end of the horizontal moving mechanism, and a vertical transmission shaft assembled on the moving end of the horizontal moving mechanism via at least one bearing and whose upper end is connected to the output shaft of the motor. The sandpaper flap wheel is detachably assembled on the transmission shaft.

[0010] Preferably, the drive shaft has a flange protruding from the middle that can contact the top of the sandpaper flap wheel, and a hexagonal pressure plate is threaded onto the lower end of the drive shaft.

[0011] Preferably, the pressure plate includes a rigid pressure plate and a rubber pressure plate fitted on the lower surface of the rigid pressure plate.

[0012] Preferably, the housing is provided with an openable cabinet door on the side away from the workbench.

[0013] According to the above technical solution, the grinding device provided by this utility model has the following beneficial effects during use: Firstly, the sandpaper flap wheel can grind the ends of the aluminum profiles it passes through during its movement. After grinding, it continues to grind the aluminum profiles located behind it. At this time, the pressing mechanism corresponding to the already ground aluminum profile can be activated, thereby adjusting the end of the aluminum profile or replacing it with an unground aluminum profile. When the sandpaper flap wheel grinds other aluminum profiles, it can replace the already ground aluminum profiles, thereby improving grinding efficiency. Secondly, the spacing between two adjacent positioning plates and the number of positioning plates can be adjusted, and the pressing mechanism can also be adjusted accordingly, enabling the grinding of aluminum profiles of different specifications, or grinding of aluminum profiles of different specifications simultaneously. It is highly practical.

[0017] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0019] like Figure 1-5As shown, a grinding device includes: a worktable 2 through which a plurality of parallel first strip-shaped grooves 1 are provided; a mounting bracket 3 mounted on the worktable 2; a plurality of vertical positioning plates 4 spaced apart along the length direction of the first strip-shaped grooves 1 and detachably mounted at the first strip-shaped grooves 1; a plurality of pressing mechanisms detachably mounted on the mounting bracket 3 and corresponding one-to-one with the plurality of positioning plates 4 and adjustable along the length direction of the first strip-shaped grooves 1; a housing 5 fixedly mounted on the side of the worktable 2 and close to the mounting bracket 3; and a grinding unit mounted inside the housing 5. The housing 5 is provided with a window portion 6 corresponding to the first strip-shaped through groove 1, and the polishing unit includes a sandpaper flap wheel 7 that can slide along the length direction of the first strip-shaped through groove 1 and can rotate.

[0020] In the above technical solution, the aluminum profile is first attached to the corresponding positioning plate 4. The function of the positioning plate 4 is to facilitate the positioning of the aluminum profile. The aluminum profile is adjusted so that the end is inserted into the window part 6. The corresponding pressing mechanism moves down to press the aluminum profile. After each pressing mechanism presses on the corresponding aluminum profile, the sandpaper flap wheel 7 in the grinding unit moves along the length direction of the first strip groove 1, and the sandpaper flap wheel 7 rotates while moving. During the movement, the sandpaper flap wheel 7 can grind the end of the aluminum profile it passes through. When the sandpaper flap wheel 7 passes over the aluminum profile, it will grind the end of the aluminum profile. After grinding, it will continue to move and grind the aluminum profiles located behind it. At this time, the pressing mechanism corresponding to the aluminum profile that has been ground can be activated, so as to adjust the end of the aluminum profile or replace it with an unground aluminum profile. When the sandpaper flap wheel 7 grinds other aluminum profiles, it can replace the aluminum profiles that have been ground, thereby improving the grinding efficiency. After the sandpaper flap wheel 7 grinds a row of aluminum profiles, it stops rotating and returns to its original position, and then starts again. When aluminum profiles have different specifications, the spacing between two adjacent positioning plates 4 can be adjusted, as can the number of positioning plates 4. Simultaneously, the pressing mechanism can be adjusted accordingly, allowing for the grinding of aluminum profiles of different specifications, or even simultaneous grinding of aluminum profiles of different specifications. It is highly practical.

[0021] In a preferred embodiment of this utility model, at least one second strip-shaped through groove 8 is provided through the top of the mounting bracket 3, and the pressing mechanism includes a vertical pressing cylinder 9, a pressure plate 10 connected to the moving end of the pressing cylinder 9, a connecting frame 11 fixedly connected to the pressing cylinder 9, a plurality of first mounting bolts passing through the second strip-shaped through groove 8 and assembled on the pressure plate 10, and a button box 12 assembled on the connecting frame 11.

[0022] In the above technical solution, loosening the first mounting bolt allows it to slide within the second strip groove 8, thereby adjusting the position of the pressing cylinder 9; loosening and removing the first mounting bolt allows the pressing mechanism to be removed from the mounting top frame 3; passing the first mounting bolt through the second strip groove 8 and the connecting frame 11 and tightening it allows the pressing mechanism to be assembled onto the mounting top frame 3. Each pressing cylinder 9 is equipped with a separate button, which facilitates the control of the lifting and lowering of the moving end of the pressing cylinder 9.

[0023] In a preferred embodiment of this utility model, the positioning plate 4 is provided with a plurality of vertical mounting holes, and a second mounting bolt 13 is inserted into each mounting hole and slidably passes through the first strip groove 1 and is assembled on the workbench 2.

[0024] In the above technical solution, by loosening the second mounting bolt 13, the second mounting bolt 13 can slide within the first strip groove 1, thereby adjusting the position of the positioning plate 4 and facilitating the installation and removal of the positioning plate 4.

[0025] In a preferred embodiment of this utility model, a washer 14 is fitted on the lower end of a plurality of second mounting bolts 13, and the upper surface of the washer 14 is provided with anti-slip texture that contacts the lower surface of the workbench 2.

[0026] In the above technical solution, both the gasket 14 and the anti-slip texture can play a role in preventing loosening.

[0027] In a preferred embodiment of the present invention, the grinding unit further includes a horizontal moving mechanism 15 assembled inside the housing 5 and whose moving end moving direction is parallel to the length direction of the first strip groove 1, a motor 16 assembled on the moving end of the horizontal moving mechanism 15, and a vertical transmission shaft 17 assembled on the moving end of the horizontal moving mechanism 15 through at least one bearing and whose upper end is connected to the output shaft of the motor 16. The sandpaper flap wheel 7 is detachably assembled on the transmission shaft 17.

[0028] In the above technical solution, the horizontal moving mechanism 15 is an existing mature technology. It can be a lead screw slide table. The horizontal moving mechanism 15 drives the motor 16 and the transmission shaft 17 to move. The motor 16 drives the transmission shaft 17 to rotate, thereby driving the sandpaper flap wheel 7 to rotate, so that a row of aluminum profiles can be polished in sequence.

[0029] In a preferred embodiment of the present invention, the transmission shaft 17 has a flange protruding from the middle that can contact the top of the sandpaper flap wheel 7, and a hexagonal pressure plate 10 is threaded onto the lower end of the transmission shaft 17.

[0030] In the above technical solution, the sandpaper flap wheel 7 can be replaced by loosening the hexagonal pressure plate 10, and the new sandpaper flap wheel 7 can be fitted onto the lower end of the drive shaft 17 and the hexagonal pressure plate 10 can be tightened. The operation is simple and convenient.

[0031] In a preferred embodiment of the present invention, the pressure plate 10 includes a rigid pressure plate and a rubber pressure plate fitted on the lower surface of the rigid pressure plate.

[0032] In the above technical solution, the combination of rigid pressure plate and rubber pressure plate can both compress the aluminum profile and avoid damaging it.

[0033] In a preferred embodiment of this utility model, the housing 5 is provided with an openable cabinet door on the side away from the workbench 2.

[0034] In the above technical solution, opening the cabinet door allows for the replacement of the sandpaper flap wheel 7, and also facilitates the inspection and maintenance of other damaged parts.
