Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a grinding angle plate for a belt sander. Background Technology

[0002] A belt sander is a common processing equipment for both metallic and non-metallic materials, primarily used for grinding and cutting. It operates based on the grinding and cutting principles of a belt sander, using the rotation and friction of the belt to grind and finish the workpiece.

[0003] Currently, belt sanders typically require a sharpening fixture to support the blades during sharpening. Existing sharpening fixtures are mounted on the belt sander's mounting plate via a sleeve. The sleeve contains spring plates that clamp the belt sander's mounting plate for installation. A blade support plate is rotatably mounted on the sleeve to facilitate sharpening.

[0004] The existing technology has at least the following problems: First, because the sharpening fixture is mounted on the mounting plate through a sleeve, the same product can only achieve one of the sharpening methods, either forward or reverse, requiring two sets of symmetrical fixtures to complete both sharpening methods; second, the tool support plate cannot be raised or lowered, and cannot be well adapted to abrasive belts of different thicknesses. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a grinding angle plate for belt sanders. This invention is easy to install, allows for both forward and reverse grinding of the same product, and is compatible with sanding belts of different thicknesses, effectively improving the efficiency and effectiveness of belt sander grinding.

[0006] The technical solution of this utility model to solve the technical problem is as follows: a grinding angle plate for a belt sander includes an installation angle steel, a lifting plate slidably provided on the outer side of the side plate of the installation angle steel, an adjustment plate rotatably provided on the lifting plate, and a support plate vertically provided on the top of the adjustment plate, the support plate being located above the top plate of the installation angle steel.

[0007] As an optimization, a U-shaped steel section is horizontally installed on the inner side of the angle steel side plate. A gap is provided between the top of the U-shaped steel section and the top plate of the angle steel, and a mounting bolt is provided at the bottom of the U-shaped steel section. By setting the U-shaped steel section and the mounting bolt, the angle steel section can be used to clamp the mounting plate on the belt sander, thereby completing the installation.

[0008] As an optimization, adjusting bolts are provided on the inner side of the mounting angle steel, and slotted holes are provided at both ends of the mounting angle steel side plate. The shank of the adjusting bolt passes through the slotted hole and connects to the lifting plate. By setting the slotted hole and adjusting bolt, the lifting plate can be adjusted, thereby raising and lowering the adjustment plate and support plate. The slotted hole ensures the stability of the raising and lowering, and the adjusting bolt can lock the position of the lifting plate to ensure stability during sharpening.

[0009] As an optimization, a guide plate is provided on the outer side of the angle steel side plate, and a guide groove is provided on the lifting plate to cooperate with the guide plate. By setting the guide plate and guide groove, the left and right swaying of the lifting plate can be prevented, further ensuring the stability of the lifting plate during lifting and lowering, as well as the stability during sharpening.

[0010] As an optimization, the lifting plate has an arc-shaped guide rail on the side facing the adjusting plate, and the adjusting plate has an arc-shaped hole that matches the arc-shaped guide rail. By setting the arc-shaped guide rail and the arc-shaped hole, the stability of the adjusting plate during rotation can be ensured, and the rotation angle can be guaranteed to be accurate.

[0011] As an optimization, both ends of the arc-shaped guide rail are equipped with positioning bolts, and the adjusting plate is connected to the lifting plate through the positioning bolts. By setting the positioning bolts, the adjusting plate can be easily loosened or locked, facilitating adjustment and locking.

[0012] As an optimization, the adjustment plate is equipped with angle scale lines, and the lifting plate also has a pointer plate on the side facing the adjustment plate, with pointers corresponding to the angle scale lines. By setting the angle scale lines and pointer plate, it is convenient for operators to rotate the adjustment plate to the required angle for sharpening.

[0013] As an optimization, the edge of the adjustment plate is rounded, and the edge of the pointer plate mates with the edge of the adjustment plate. This, combined with the arc-shaped guide rail and arc-shaped hole, further ensures the stability of the adjustment plate's rotation and allows the pointer to accurately point to the angle scale line, avoiding skewness.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By incorporating an angle iron, the device can be connected to the mounting plate on the belt sander, and can be installed from either the left or right side of the sander. This allows for both forward and reverse grinding with the same product. A lifting plate allows for adjusting the height of the adjustment plate and the gap between the support plate and the top plate of the angle iron, thus accommodating belts of different thicknesses. An adjusting plate allows for adjusting the tilt angle of the support plate, thereby adjusting the grinding angle. The support plate also supports the blade body, facilitating grinding. This invention is convenient to install, allows for both forward and reverse grinding with the same product, and is compatible with belts of varying thicknesses, effectively improving the efficiency and effectiveness of belt sander grinding.

[0023] Example 1

[0024] Figures 1 to 5 As one embodiment of this utility model, such as Figures 1 to 5 As shown, a grinding angle plate for a belt sander includes a mounting angle steel 1, which includes a side plate and a top plate. A lifting plate 2 is slidably provided on the outer side of the side plate of the mounting angle steel 1. An adjusting plate 3 is rotatably provided on the lifting plate 2. A support plate 4 is vertically provided on the top of the adjusting plate 3. The adjusting plate 3 and the support plate 4 are integrally formed. The support plate 4 is located above the top plate of the mounting angle steel 1. The bottom end of the support plate 4 near the top plate of the mounting angle steel 1 has a chamfer.

[0025] By setting the mounting angle steel 1, it can be connected to the mounting plate on the belt sander 15, and can be installed from both the left and right sides of the belt sander 15. The same product can realize both forward and reverse edge sharpening. By setting the lifting plate 2, the height of the adjusting plate 3 can be raised or lowered, and the gap between the support plate 4 and the top plate of the mounting angle steel 1 can be adjusted, thereby adapting to sanding belts 16 of different thicknesses. By setting the adjusting plate 3, the tilt angle of the support plate 4 can be adjusted, thereby adjusting the sharpening angle. By setting the support plate 4, the blade body can be supported, making sharpening convenient.

[0026] like Figures 1 to 5 As shown, a U-shaped steel 5 is horizontally provided on the inner side of the side plate of the mounting angle steel 1. There is a gap between the top of the U-shaped steel 5 and the top plate of the mounting angle steel 1, and a mounting bolt 6 is provided at the bottom of the U-shaped steel 5. By setting the U-shaped steel 5 and the mounting bolt 6, the mounting angle steel 1 can be used to clamp the mounting plate on the belt sander 15, thereby completing the installation.

[0027] like Figures 2 to 4As shown, an adjusting bolt 7 is provided on the inner side of the mounting angle steel 1, and slotted holes 8 are provided at both ends of the side plate of the mounting angle steel 1. The slotted holes 8 are located on both sides of the U-shaped steel 5, and the rod of the adjusting bolt 7 passes through the slotted holes 8 and connects to the lifting plate 2. By setting the slotted holes 8 and the adjusting bolt 7, the lifting plate 2 can be adjusted, thereby raising and lowering the adjusting plate 3 and the support plate 4. The slotted holes 8 can ensure the stability of the raising and lowering, and the adjusting bolt 7 can lock the position of the lifting plate 2 to ensure the stability during sharpening.

[0028] like Figure 1 and Figure 4 As shown, a guide plate 9 is provided on the outer side of the side plate of the mounting angle steel 1, and a guide groove 10 is provided on the lifting plate 2 to cooperate with the guide plate 9. By setting the guide plate 9 and the guide groove 10, the left and right swaying of the lifting plate 2 can be prevented, further ensuring the stability of the lifting plate 2 during lifting and lowering, as well as the stability during sharpening.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the lifting plate 2 has an arc-shaped guide rail 11 on the side facing the adjusting plate 3, and the adjusting plate 3 has an arc-shaped hole 12 that matches the arc-shaped guide rail 11. By setting the arc-shaped guide rail 11 and the arc-shaped hole 12, the stability of the adjusting plate 3 during rotation can be ensured, and the rotation angle can be guaranteed to be accurate.

[0030] like Figure 1 and Figure 4 As shown, both ends of the arc-shaped guide rail 11 are equipped with positioning bolts 13, and the adjusting plate 3 is connected to the lifting plate 2 through the positioning bolts 13. By setting the positioning bolts 13, the adjusting plate 3 can be easily loosened or locked, facilitating adjustment and locking.

[0031] like Figure 1 and Figure 4 As shown, the adjusting plate 3 has angle scale lines, and the lifting plate 2 has a pointer plate 14 on the side facing the adjusting plate 3. The pointer plate 14 has a pointer corresponding to the angle scale lines. By setting the angle scale lines and the pointer plate 14, the operator can easily rotate the adjusting plate 3 to the required angle for sharpening.

[0032] like Figure 1 and Figure 4 As shown, the edge of the adjusting plate 3 is arc-shaped, and the edge of the pointer plate 14 mates with the edge of the adjusting plate 3. This mates with the arc-shaped guide rail 11 and the arc-shaped hole 12, further ensuring the stability of the rotation of the adjusting plate 3 and ensuring that the pointer accurately points to the angle scale line, avoiding skewness.

[0033] When using, such as Figure 5As shown, first, the mounting angle steel 1 is installed onto the mounting plate of the belt sander 15, so that the mounting plate of the belt sander 15 is inserted between the U-shaped steel 5 and the top plate of the mounting angle steel 1. The sanding belt 16 is located between the top plate of the mounting angle steel 1 and the support plate 4. Then, the mounting bolts 6 are tightened so that the shank of the mounting bolts 6 abuts against the bottom of the mounting plate of the belt sander 15. Then, according to the thickness of the sanding belt 16, the two sets of adjusting bolts 7 are loosened to adjust the position of the lifting plate 2. After adjustment, the adjusting bolts 7 are tightened to lock the lifting plate 2. Finally, the two sets of positioning bolts 13 are loosened, and the adjusting plate 3 is rotated. The operator can determine the tilt angle of the support plate 4 by the angle scale line pointed to by the pointer, thereby adjusting the grinding angle. This utility model is convenient to install, can achieve both forward and reverse grinding with the same product, and can be adapted to sanding belts 16 of different thicknesses, effectively improving the grinding efficiency and effect of the belt sander 15.
