Description

Technical Field

[0001] This utility model relates to the field of chamfering equipment technology, specifically to a vertical chamfering machine with adjustable chamfering cutting thickness. Background Technology

[0002] Large-size panels typically refer to panels with a side length greater than or equal to 800mm. They come in various sizes to suit different spatial needs. Existing panels generally have a regular square structure, with the decorative side perpendicular to the panel's sides. In actual renovations, due to the diversity of wall structures, when encountering interior and exterior corners, corner columns, window sills, etc., the panels need to be cut and polished to create a chamfer of approximately 45 degrees. This facilitates the splicing and combination of two panels, ensuring the panel shape meets the decoration requirements and improves the aesthetics of the renovation.

[0003] Manual handheld cutting machines are laborious for chamfering sheet metal and cannot guarantee the accuracy and quality of the chamfering. Therefore, chamfering machines are needed when chamfering sheet metal. However, existing chamfering machines have the following shortcomings when dealing with the chamfering needs of large-sized sheet metal:

[0004] 1. Large-sized boards are very heavy, and adjusting their position is difficult and inconvenient when positioning and fixing them.

[0005] 2. Although most chamfering machine structures can adjust the cutting angle of the angle grinder, they cannot adjust the thickness of the chamfer cut on the board, which is a limitation. Summary of the Invention

[0006] The main purpose of this invention is to provide a vertical chamfering machine with adjustable chamfering thickness, in order to solve the problems of existing chamfering machines being laborious to adjust the position and unable to adjust the thickness of the chamfered cutting when dealing with large-sized plates.

[0013] Furthermore, the roller assembly includes a roller fixing plate and two sets of rollers fixedly mounted on the back of the roller fixing plate. The two sets of rollers are slidably mounted on a vertical frame, and the vertical frame is provided with corresponding track grooves.

[0014] Furthermore, the angle grinder fixing component is symmetrically provided with two right-angled folded edges that are fixedly assembled with the roller fixing plate. The angle grinder fixing component is provided with mounting holes corresponding to the angle grinder in the middle. Each of the two right-angled folded edges is provided with at least one set of adjustment holes arranged in an oblique line. The oblique lines of each set of adjustment holes are parallel to each other. The roller fixing plate is provided with positioning holes that correspond one-to-one with each set of adjustment holes. One positioning hole corresponds to one set of adjustment holes.

[0015] Furthermore, the angle between the oblique line where the adjustment hole is located in each group and the vertical line where the center of the first adjustment hole is located is β, where 1°≤β≤3°.

[0016] Furthermore, the angle grinder fixture is provided with two mudguards corresponding to the angle grinder cutter. The first one is an arc-shaped structure and is fixedly mounted on the right-angle folded edge to cover the angle grinder cutter. The other one is a strip-shaped structure and is fixedly mounted on the angle grinder fixture and is positioned opposite to the first mudguard.

[0017] Furthermore, a limit switch is provided at the bottom of the roller fixing plate, and a trigger block corresponding to the limit switch is provided on the back of the bottom end of the vertical frame.

[0018] Furthermore, the included angle α ranges from 45±5°.

[0019] Furthermore, the angle grinder fixture is also provided with a handle on its outer side.

[0020] Furthermore, the vertical frame has an inclined surface on its outer side, and the roller fixing plate is arranged parallel to the inclined surface.

[0021] Furthermore, the connection end between the horizontal frame and the vertical frame is provided with a second inclined surface, which is parallel to the angle grinder cutter.

[0046] Please refer to Figures 1 to 9 This utility model provides a vertical chamfering machine with adjustable chamfering thickness, mainly used for chamfering large-size plates with a side length greater than or equal to 800mm. It includes a positioning frame 1, a lower positioning component 2, a limiting component 3, a roller assembly 4, and an angle grinder 5, wherein:

[0047] Positioning bracket 1 is used to position the bottom edge and back of the board, such as... Figure 1 , Figure 2 and Figure 3 The device includes a horizontal frame 11 and a vertical frame 12 arranged vertically in an "L" shape, one in front of the other. The top surface of the horizontal frame 11 is provided with several horizontally arranged pulleys 13. The top surface of the horizontal frame 11 is provided with a groove for installing the pulleys 13. All the pulleys 13 are fixedly assembled in the groove in a horizontal line. The back of the horizontal frame 11 and the vertical frame 12 are also provided with a diagonal support 14 for positioning the back of the board. The horizontal frame 11 positions the bottom edge of the board, and the diagonal support 14 positions the back of the board. The bottom edge of the large-sized board rests on the pulleys 13, which can easily realize the adjustment of its lateral position, saving time and effort.

[0048] The lower positioning component 2 is fixedly installed at the connection end between the horizontal frame 11 and the vertical frame 12, such as... Figure 1 It has a positioning surface 21 that is flush with the outer side of the vertical frame 12 and is used to position the chamfered side of the board. When adjusting the horizontal position of the board located on the pulley 13, it needs to be adjusted horizontally until the chamfered side of the board touches the positioning surface 21 to achieve the positioning of the chamfered side of the board.

[0049] The limiting member 3, which is slidably installed on the front of the vertical frame 12, is used to position the top edge and front of the plate. Figure 2 The system includes a limiting mounting base 31 and a pressing and positioning component 32 threaded onto the limiting mounting base 31 for positioning the front of the plate. When positioning the top edge of the plate, the position of the limiting mounting base 31 is adjusted downward so that it abuts against the top edge of the plate after the bottom edge, back edge and chamfer side edge positioning have been completed. Then, it is locked to achieve positioning of the top edge of the plate. Finally, the tightness of the pressing and positioning component 32 is adjusted so that it abuts against the front of the plate to achieve positioning of the front of the plate. Through the cooperation of the positioning frame 1, the lower positioning component 2 and the limiting component 3, the plate is stably positioned in all directions, which facilitates subsequent chamfering and cutting operations.

[0050] The roller assembly 4 is slidably mounted on the vertical frame 12, and includes a roller fixing plate 41 and two sets of rollers 42 fixedly mounted on the back of the roller fixing plate 41, such as... Figure 3 and Figure 4 Two sets of rollers 42 are slidably mounted on the vertical frame 12, and the vertical frame 12 is provided with corresponding track grooves 121, such as... Figure 8The roller assembly 4 is designed to enable the angle grinder 5 to move up and down.

[0051] Angle grinder 5 is fixedly mounted on roller assembly 4, such as Figure 1 , Figure 2 and Figure 7 The cutting blade of the angle grinder 5 forms an angle α with the plane of the board, with the angle α ranging from 45±5°. The angle grinder 5 is fixedly assembled with the roller assembly 4 via the angle grinder fixing part 6. The assembly position of the angle grinder fixing part 6 and the roller assembly 4 is adjustable, so that the cutting thickness can be adjusted when the angle grinder 5 is chamfering the vertical edge of the board. Specifically,

[0052] like Figure 5 and Figure 6 The angle grinder fixing component 6 has two symmetrical right-angled flanges 61 that are fixedly assembled with the roller fixing plate 41. The angle grinder fixing component 6 has mounting holes 62 in the middle corresponding to the angle grinder 5. Each of the two right-angled flanges 61 has at least one set of adjustment holes 63 arranged diagonally. Each set of adjustment holes 63 contains multiple holes, and the diagonal lines of each set of adjustment holes 63 are parallel to each other. The roller fixing plate 41 has positioning holes 43 that correspond one-to-one with each set of adjustment holes 63. One positioning hole 43 corresponds to one set of adjustment holes 63. By fixing the positioning holes 43 to the adjustment holes 63 in different sequences, the relative position between the angle grinder 5 and the plate is adjusted, thereby adjusting the thickness of the chamfer cut. The positioning holes 43 and the adjustment holes 63 are fixedly assembled using bolts and nuts. More specifically…

[0053] like Figure 6 The angle between the diagonal line where each set of adjustment holes 63 is located and the vertical line where the center of the first adjustment hole 63 (counted from top to bottom or from bottom to top) is β, 1°≤β≤3°. There is a certain lateral distance between two adjacent holes in each set of adjustment holes 63. By fixing the positioning hole 43 to the adjustment holes 63 in different sequences, the relative distance between the angle grinder 5 and the roller fixing plate 41 and the side of the plate is adjusted, thereby adjusting the thickness of the chamfer cut of the side of the plate by the angle grinder 5.

[0054] It should be understood that one positioning hole 43 corresponds to a set of adjustment holes 63. Taking two positioning holes 43 as an example, if the first positioning hole 43 is assembled and connected with the first hole of the corresponding set of adjustment holes 63, the other positioning hole 43 should also be fixedly connected with the first hole of the other set of adjustment holes 63.

[0055] If the first positioning hole 43 is assembled and connected to the third hole of the corresponding group adjustment hole 63, the other positioning hole 43 should also be fixedly connected to the third hole of the other group adjustment hole 63, and so on.

[0056] Normally, when the angle grinder 5 is performing chamfering operations, an external water pipe needs to be installed to rinse the chamfered area to reduce dust and cool the cutting blade. The dust generated will form mud when it comes into contact with the rinsing water, which is prone to splashing. Therefore, the angle grinder mounting bracket 6 is equipped with two mudguards 7 corresponding to the cutting blade of the angle grinder 5. Figure 1 and Figure 2 The first one is an arc-shaped structure and is fixedly mounted on the right-angle folded edge 61 to cover the cutter of the angle grinder 5. The other one is a strip-shaped structure and is fixedly mounted on the angle grinder fixing part 6, opposite to the first mudguard 7. The two mudguards 7 can effectively block the splashing of debris, mud and other particles.

[0057] This utility model is a vertical chamfering machine. After the board is positioned, it can automatically chamfer and cut the sides of the board without manual intervention, relying on the weight of the roller assembly 4, the angle grinder 5, and the angle grinder fixing part 6. To achieve the function of automatically shutting off the angle grinder 5 after the entire cutting stroke is completed in automatic mode, a limit switch 8 is provided at the bottom of the roller fixing plate 41, and a trigger block 9 corresponding to the limit switch 8 is provided on the back of the bottom end of the vertical frame 12. Figure 2 and Figure 3 Limit switch 8 should be associated with the angle grinder 5 switch and the external water pump switch. After the entire cutting stroke is completed, when the roller assembly 4 moves the angle grinder 5 to the bottom of the vertical frame 12, limit switch 8 contacts the trigger block 9, and limit switch 8 immediately closes, causing the angle grinder 5 and the external water pump to stop simultaneously. The circuit connection involved is a conventional circuit, such as... Figure 9 You can connect it yourself according to the circuit principle.

[0058] To prevent interference between the cutting blade of the angle grinder 5 and the end of the horizontal frame 11, an inclined surface 111 is provided at the connection end between the horizontal frame 11 and the vertical frame 12, such as... Figure 1 and Figure 8 The second inclined plane 111 is parallel to the cutter of the angle grinder 5. Note that the setting of the second inclined plane 111 should ensure that the cutter of the angle grinder 5 will not interfere with the end of the horizontal frame 11 when the cutting thickness of the angle grinder 5 is at its maximum.

[0059] To facilitate the positioning and installation of the angle grinder 5 and the setting of the chamfer angle, the outer side of the vertical frame 12 is provided with an inclined surface 122, such as... Figure 2 , Figure 7 and Figure 8 The roller fixing plate 41 and the inclined plane 122 are set in parallel. The acute angle between the cutter of the angle grinder 5 and the plane where the board is located is the chamfer angle α. The cutter of the angle grinder 5 and the roller fixing plate 41 are set in perpendicular. In this way, by setting the angle between the inclined plane 122 and the plane where the board is located to 90°-α, the chamfer angle of the angle grinder 5 on the board can be determined by setting the angle of the inclined plane 122.

[0060] To facilitate manual operation, a handle 10 is provided on the outside of the angle grinder fixture 6. Holding the handle 10 allows for the purposeful movement of the angle grinder 5 by hand.

[0061] This utility model achieves stable positioning of large-sized plates through positioning frame 1, lower positioning component 2 and limiting component 3. The positioning adjustment of large-sized plates can be easily achieved by several pulleys 13 set on the horizontal frame 11. Furthermore, the thickness of the chamfering cut of the side edge of the plate can be adjusted by adjusting the assembly position of the angle grinder 5 and the roller assembly 4 (the positioning hole 43 is fixedly assembled with the upper adjustment hole 63 in different sequences).

[0062] This invention is also applicable to other fields that require chamfering, such as chamfering of tiles, boards, and profiles, and can also achieve the purpose of adjustable chamfering cutting thickness.

[0063] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
