Description

Technical Field

[0001] This application relates to the field of polishing equipment technology, and more particularly to a flat iron pusher block for abrasive belts. Background Technology

[0002] A belt sander is a common surface treatment tool, mainly used for grinding, polishing, and deburring various materials. It is typically driven by an electric motor, which drives one or more rotating rollers fitted with a sanding belt (also called a sandpaper belt). The sanding belt is used to grind, polish, and deburr the workpiece surface to improve its surface quality and smoothness. Due to the flexibility and adjustability of the sanding belt, belt sanders can be used to process complex-shaped workpiece surfaces, such as curves and chamfers.

[0003] When grinding a flat workpiece surface, the surface of the abrasive belt must also be flat. This requires a flat pad on the back of the abrasive belt to engage with the belt and keep the front of the belt flat. However, the flat pads on existing belt sanders are usually a single piece. Prolonged and high-intensity friction from the abrasive belt causes wear on the contact surface of the flat pad, resulting in an uneven contact surface. This necessitates frequent replacement of the flat pad.

[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0032] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as there is no conflict between them.

[0033] The utility model provides a kind of Figure 1 、 Figure 2 、 Figure 4The utility model discloses a flat iron push block for abrasive belt is used to abut against the abrasive belt on the abrasive belt machine, makes the front surface of abrasive belt keep flat, and the flat surface of workpiece is polished through the flat surface of abrasive belt. Its main structure includes: push block body 1, at least two driven rollers 2 and abutment plate 3, push block body 1 is installed on the abrasive belt machine, and located on the abrasive belt path. Push block body 1 is provided with abutment platform 121 on one side;Two driven rollers 2 are arranged on the both sides of abutment platform 121 in the first direction respectively, and driven roller 2 is used to roll the abrasive belt. When using, the outer periphery of driven roller 2 is passed through by the abrasive belt, and the abrasive belt moves and drives driven roller 2 to rotate, and the rolling resistance of abrasive belt can be reduced through the rolling of driven roller 2, and the energy consumption is reduced;Abutment plate 3 is detachably connected on abutment platform 121, and abutment plate 3 includes abutment surface 31, and the abutment surface 31 keeps smooth and flat, and the abutment surface 31 is used to abut against the abrasive belt;Wherein, the abutment surface 31 is tangent to the outer periphery of two driven rollers 2, and then the abrasive belt can move through driven roller 2 and abutment plate 3. The gap between the back surface of abrasive belt and the abutment surface 31 of abutment plate 3 is as small as possible, and the part corresponding to the abutment surface 31 on the abrasive belt keeps flat, so that the flat surface of workpiece is polished better.

[0034] It should be noted that the existing flat iron push block for abrasive belt machine is usually integrally arranged, and the long-time and high-strength friction of the abrasive belt can cause the abutment surface 31 of the flat iron push block to be worn, and then the abutment surface 31 of the flat iron push block is not flat. The whole flat iron push block needs to be frequently replaced.

[0035] The utility model discloses a flat iron push block for abrasive belt is used to abut against the abrasive belt on the abrasive belt machine, makes the front surface of abrasive belt keep flat, and the flat surface of workpiece is polished through the flat surface of abrasive belt. Its main structure includes: push block body 1, at least two driven rollers 2 and abutment plate 3, push block body 1 is installed on the abrasive belt machine, and located on the abrasive belt path. Push block body 1 is provided with abutment platform 121 on one side;Two driven rollers 2 are arranged on the both sides of abutment platform 121 in the first direction respectively, and driven roller 2 is used to roll the abrasive belt. When using, the outer periphery of driven roller 2 is passed through by the abrasive belt, and the abrasive belt moves and drives driven roller 2 to rotate, and the rolling resistance of abrasive belt can be reduced through the rolling of driven roller 2, and the energy consumption is reduced;Abutment plate 3 is detachably connected on abutment platform 121, and abutment plate 3 includes abutment surface 31, and the abutment surface 31 keeps smooth and flat, and the abutment surface 31 is used to abut against the abrasive belt;Wherein, the abutment surface 31 is tangent to the outer periphery of two driven rollers 2, and then the abrasive belt can move through driven roller 2 and abutment plate 3. The gap between the back surface of abrasive belt and the abutment surface 31 of abutment plate 3 is as small as possible, and the part corresponding to the abutment surface 31 on the abrasive belt keeps flat, so that the flat surface of workpiece is polished better.

[0036] Further, the abutment plate 3 is a ceramic plate.

[0037] It should be noted that the hardness of ceramic is usually higher than that of many metals and plastics. This makes ceramic widely used in some occasions that require high wear resistance, such as cutters, bearings, etc. Moreover, ceramic has good high-temperature resistance and can be used in high-temperature environments for a long time without deformation or softening. Therefore, the flat surface of the ceramic plate is smooth and wear-resistant, and can be rubbed with the surface of the abrasive belt for a long time at high strength without wear and deformation.

[0038] Further, as Figure 2 , Figure 4As shown, the push block body 1 comprises a mounting base 11 for fixing the connection of the belt sander and a platform base 12 arranged on the mounting base 11, and an abutting platform 121 arranged on one side of the platform base 12.

[0039] The two ends of the platform base 12 in the second direction are respectively detachably provided with two abutting pieces 122, the abutting pieces 122 are used for abutting the fixed abutting plate 3, and the two first directions are perpendicular to the second direction. The second direction is the vertical direction. The two abutting pieces 122 are respectively abutted at the two ends of the abutting plate 3 in the vertical direction, that is, the two side positions of the belt. The abutting piece 122 is detachably connected to the platform base 12. When the abutting plate 3 needs to be replaced, only the abutting piece 122 at one end of the abutting plate 3 needs to be detached, and the abutting plate 3 can be pulled out from one side of the belt for replacement.

[0040] Further, as shown in Figure 2 , Figure 4 At least one abutting piece 122 is provided with an adjusting plate 123, the abutting piece 122 is fixed to the platform base 12 through the adjusting plate 123, and the installation position of the adjusting plate 123 can be adjusted along the third direction perpendicular to the first direction and the second direction. The adjusting plate 123 can adjust the gap between the abutting piece 122 and the contact surface of the abutting plate 3. In actual installation, the gap between the abutting piece 122 and the contact surface of the abutting plate 3 is zero. The adjusting plate 123 is provided to make the abutting piece 122 adapt to abutting plates 3 of different thicknesses.

[0041] Further, as shown in Figure 3 The adjusting plate 123 is provided with an elastic member 124, and the elastic member 124 is used for extending the adjusting plate 123 in the direction away from the abutting platform 121. When the abutting piece 122 is not tightened with a bolt, the abutting plate 3 can be preliminarily clamped by the abutting piece 122 through the elastic member 124.

[0042] Further, as shown in Figure 4 The two abutting platforms 121 are provided with limiting grooves 125 matched with the abutting plate 3, the limiting grooves 125 are used for accommodating the abutting plate 3, and the depth size of the limiting grooves 125 is smaller than the thickness size of the abutting plate 3. Therefore, the abutting surface 31 of the abutting plate 3 is higher than the height of the side wall of the limiting groove 125. The abutting surface 31 can directly contact the back surface of the belt.

[0043] Further, as shown in Figure 4As shown, the limiting groove 125 is provided with a notch 126 on one side in the second direction, and the notch 126 is used for pulling out the abutting plate 3 or inserting the abutting plate 3. When the abutting plate 3 is worn and the surface is uneven, the abutting plate 3 can be loosened by disassembling the abutting piece 122 close to the notch 126. Then the abutting plate 3 is pulled out from the notch 126, and a new abutting plate 3 is inserted into the limiting groove 125 from the notch 126, without the need to replace the entire push block, effectively saving the cost of replacing the flat iron push block.

[0044] Further, as shown in Figure 2 、 Figure 4 , the mounting base 11 is provided with two limiting bases 111, and the two limiting bases 111 are respectively arranged on both sides of the platform base 12. The platform base 12 is provided with an upper base 127 at one end away from the mounting base 11, and the upper base 127 and the limiting base 111 are respectively used for mounting two ends of the driven roller 2.

[0045] The driven roller 2 is provided with bearings at both ends, and the bearings at both ends of the driven roller 2 are respectively fixed on the upper base 127 and the limiting base 111.

[0046] Further, the mounting positions of the two upper bases 127 and the limiting bases 111 can be adjusted in a third direction.

[0047] The third direction is perpendicular to the first direction and the second direction, that is, the third direction is perpendicular to the plane of the abrasive belt. By adjusting the mounting positions of the two upper bases 127 and the limiting bases 111 in the third direction, the outer periphery of the driven roller 2 and the abutting surface 31 of the abutting plate 3 can be tangent as much as possible, and then the abutting surface 31 is in contact with the back surface of the abrasive belt. Finally, the abrasive belt presents a flat polishing surface to polish the flat surface of the workpiece.

[0048] In summary, the application provides a flat iron push block for an abrasive belt. The abutting plate 3 which is wear-resistant and replaceable is used to abut the back surface of the abrasive belt, so that the front surface of the abrasive belt presents a flat state to polish the flat surface of the workpiece. When the abutting plate 3 is worn and the surface is uneven, it can be replaced. Moreover, the flat iron push block does not need to be disassembled as a whole during the replacement of the abutting plate 3, and the effect of quick replacement can be achieved. The cost of replacing the flat iron push block and the operating cost of the polishing machine as a whole are effectively saved.

[0049] Obviously, the above embodiments are only examples for clear illustration, and are not limitations on the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments do not need to be exhausted, and the obvious changes or variations still fall within the protection scope of the application.
