Definitions

  • the present invention relates to a grinding machine for grinding non-horizontal grinding surfaces, particularly surfaces comprising non-planar or curved portions, and more particularly to a grinding machine comprising a grinding pad which performs a grinding stroke for adapting the continuous irregular non-horizontal grinding surfaces correspondingly.
  • a driving unit of the grinding machine is connected to a receiving plate, and the receiving plate and a grinding pad are connected with a deforming member.
  • the grinding pad and the receiving plate are horizontal and the deforming member is not deformed.
  • the deforming member is deformed and relatively offset based on the center line of the grinding pad, allowing the two ends of the grinding pad being deformed along the radian of the non-horizontal grinding surface to fit to the non-horizontal grinding surface.
  • the deforming members of the above patents adopt a lever shaft connection method or a design of an elastic element such as a spring, they comprise only a single deformed state between the grinding pad and the receiving plate, limiting the deformation degree of the deforming members. Therefore, when grinding a non-horizontal grinding surfaces with a large radian, it is practically impossible to fit to the grinding surface and the grinding efficiency is reduced.
  • the conventional lever shaft connection method such as U.S. Patent No. US 9,833,871 , the deforming members on both sides must simultaneously deform to maintain a horizontal state between the receiving plate and the grinding pad.
  • the non-horizontal grinding surface cannot provide the same radian corresponding to both ends of the grinding pad, especially in a continuous uneven wave-like non-horizontal grinding surface.
  • This type of grinding machine will not be able to effectively conform to the changes of the non-horizontal grinding surface to perform grinding operations.
  • a primary object of the present invention is to solve the problem in the conventional techniques being unable to effectively fit to continuous irregular non-horizontal grinding surfaces correspondingly to perform grinding strokes.
  • the present invention provides a grinding machine for grinding non-horizontal grinding surfaces, particularly surfaces non-planar or (convexly and/or concavely) curved portions, comprising a deformation device disposed between a grinding power source and a grinding pad driven by the grinding power source.
  • the deformation device comprises at least one receiving unit for holding the grinding power source.
  • the receiving unit defines a reference horizontal line.
  • the deformation device comprises a set of an offset unit, a first deformation member and a second deformation member disposed near one end of the grinding pad, wherein the offset units, the first deformation member and the second deformation member define a first deformation angle and a second deformation angle.
  • one end of the grinding pad is fitted to various non-horizontal grinding surfaces, especially continuous irregular non-horizontal grinding surfaces, independently through the variable angles of one of the first and the second deformation angles or the combination of the both. Furthermore, the receiving unit of the present invention maintains the reference horizontal line during the grinding operation and provides excellent grinding effectiveness.
  • the two second deformation members and the first deformation member disposed at a central position of the two second deformation members assist the grinding pad to generate a deformed state in response to the non-horizontal grinding surface.
  • the two sets of the second deformation members respectively disposed at four ends of the offset unit and the two first deformation members disposed at the central position of the second deformation members assist the grinding pad to generate a deformed state in response to the non-horizontal grinding surface.
  • the grinding power source is manual
  • the receiving unit comprises an outer housing to assist in applying an external force.
  • the receiving unit further comprises a covering portion extended to the grinding pad and including an opening for connecting an external dust remover.
  • the grinding power source is a power grinding machine of one of an electric grinder or a pneumatic grinder, and the power grinding machine includes a power shaft connected to the grinding pad for carrying out grinding strokes.
  • either end of the grinding pad is correspondingly fitted to various non-horizontal grinding surfaces independently through the variable angles of the deformation angle, especially for continuous irregular non-horizontal grinding surfaces.
  • the present invention has an excellent grinding effectiveness.
  • the present invention provides a grinding machine for grinding non-horizontal grinding surfaces, comprising a grinding power source 10 and a grinding pad 30 driven by the grinding power source 10 to perform a grinding stroke on a non-horizontal grinding surface.
  • the grinding pad 30 is made of an elastic material and configured to take a deformed state for adapting the shape of the grinding pad 30 to the shape or profile of the non-horizontal grinding surface.
  • the grinding pad 30 includes a flexible metal layer at the top, a compression layer made of a flexible material such as rubber or sponge in the middle, and a deformable soft grinding layer at the bottom.
  • the grinding pad 30 with a deformed state generally is known from the prior art and has various implementation forms. That is, other embodied forms of the grinding pad 30 will not be described again because they do not belong to the technical limitations of the specification.
  • a deformation device 20 is disposed between the grinding power source 10 and the grinding pad 30.
  • the deformation device 20 comprises at least one receiving unit 21 for holding the grinding power source 10, and two offset units 22 disposed between the grinding pad 30 and the receiving unit 21.
  • the receiving unit 21 defines a reference horizontal line and the two offset units 22 are respectively disposed near two opposite ends of the receiving unit 21.
  • the deformation device 20 comprises at least one first deformation member 23 connected between each of the offset units 22 and the receiving unit 21, and at least two second deformation members 24 disposed oppositely and connected between each of the offset units 22 and the grinding pad 30.
  • the at least one first deformation member 23 is deformed independently to define a first deformation angle R1 formed between anyone of the offset units 22 and the reference horizontal line of the receiving unit 21, and at least two second deformation members 24 are deformed to define a second deformation angle R2 is formed between the grinding pad 30 and the reference horizontal line of the receiving unit 21.
  • the at least two second deformation members 24 and the at least one first deformation member 23 are arranged in a staggered configuration.
  • the at least one first deformation member 23 comprises fixing segments 232, 233 at two ends and a central deforming segment 232.

  • the fixing segments 232, 233 of the first deformation member 23 are respectively connected to the receiving unit 21 and the offset units 22, and the fixing segments 242, 243 of the second deformation members 24 are respectively connected to the offset units 22 and the grinding pad 30.
  • the first deformation member 23 and the second deformation member 24 are one of a spring, a spring piece or rubber.
  • Fig. 3A and Fig. 3B are schematic views of the deformed states of the present invention when grinding a concave surface.
  • the grinding power source 10 applies a force to the receiving unit 21 when operated by the user to grind a concave surface
  • the force applied by the grinding power source 10 and the feedback force generated from two ends of the grinding pad 30 cause the deformation of the central deforming segments 231, 241 of the first deformation member 23 and the second deformation members 24.
  • the grinding pad 30 is deformed into the deformed state in which the surface of the grinding pad 30 is fitted to the radian of the curved surface.
  • the deformation forms of the central deforming segments 231 and 241 vary according to different materials, including but not limited to the forms of one or a combination of compression or bending of the central deforming segments 231 and 241. Then, when the central deforming segment 231 of the first deformation member 23 is deformed, a first deformation angle R1 is formed between the reference horizontal line of the receiving unit 21 and the offset unit 22 since the fixing segments 232 and 233 of the first deformation member 23 is respectively connected to the receiving unit 21 and the offset units 22. Meanwhile, a second deformation angle R2 is formed between the grinding pad 30 and the reference horizontal line when the second deformation members 24 are deformed. Accordingly, the relative variations of the first deformation angle R1 and the second deformation angle R2 constitute the deformed state of the grinding pad 30, so that the grinding pad 30 effectively fits to the curved surface as shown in Fig. 3A .
  • Fig. 4A and Fig. 4B are schematic views of the deformed states of the present invention when grinding a convex surface.
  • the second deformation members 24 are deformed to define a second deformation angle R4 formed between the grinding pad 30 and the reference horizontal line of the receiving unit 21, and the first deformation members 23 is deformed to define a first deformation angle R3 formed between the offset unit 22 and the reference horizontal line of the receiving unit 21.
  • the relative variations of the first deformation angle R3 and the second deformation angle R4 constitute the deformed state of the grinding pad 30, so that the grinding pad 30 effectively fits to the convex surface as shown in Fig. 4A .
  • each end of the grinding pad 30 is able to independently fit to the non-horizontal grinding surface based on the variable angles of the first deformation angles R1, R3 and the second deformation angles R2, R4.
  • This is important for an irregular and continuous non-horizontal grinding surface as shown in Fig. 5 , when grinding a surface comprises both convex and curved surfaces simultaneously, the grinding pad 30 of the present invention is independently deformed at two ends without interlinking each other, so that the grinding pad 30 includes different radians at two ends in the deformed state to keep fitting to the grinding surface.
  • Fig. 5 when grinding a surface comprises both convex and curved surfaces simultaneously, the grinding pad 30 of the present invention is independently deformed at two ends without interlinking each other, so that the grinding pad 30 includes different radians at two ends in the deformed state to keep fitting to the grinding surface.
  • the grinding surface of one end of the grinding pad 30 is in a convex-deformed state, and the grinding surface of another end of the grinding pad 30 is in a concave-deformed state. Therefore, the grinding pad 30 of the present invention maintains the independent deformed state of each end of the grinding pad 30 to fit to the grinding surface for effectively performing the grinding strokes.
  • the grinding power source 50 of the present invention is configured for use in a power grinding machine of an electric grinder or of a pneumatic grinder.
  • the power grinding machine includes a power shaft 51 connected to the grinding pad 30, and the power grinding machine is used as the grinding power source 50 to drive the grinding pad 30 with the power shaft 51 to perform grinding strokes of linear or eccentric track.
  • the grinding pad 30 of the present invention is mainly of a rectangular shape, and the number of disposing sets of a first deformation members 23a and a second deformation members 24a are based on the different sizes of the grinding pad 30. For example, if the grinding pad 30 is larger in size, it requires a finer and more stable deformation balance during the grinding strokes.
  • the first deformation members 23a are more than two disposed, the first deformation members 23a are preferably disposed in two sets, and the two sets of the second deformation members 24a are disposed at the four end points of the offset unit 22.
  • Each of the first deformation members 23a is preferably maintained to be arranged on a vertical line at a central position of the two second deformation members 24a in a staggered manner.
  • the deformation variable of the central deforming segment 231 of the first deformation members 23a of the present invention is greater than or equal to the deformation variable of the central deforming segment 241 of the second deformation members 24a.
  • the shape of the receiving unit 21 basically corresponds to the rectangular shape of the grinding pad 30.
  • the grinding power source 10 is configured to be disposed at the central position or at the positions on the two sides of the grinding pad 30 depending on the size of the grinding pad 30.
