Definitions

  • the present disclosure relates to composite saws, and particularly to a table-cutting type protective cover for a composite saw.
  • table cutting type protective covers for a composite saw.
  • One is a passive type where the table cutting type protective cover is raised to a certain height according to the height of the workpiece before cutting.
  • the other is an automatic type where the table cutting type protective cover is an integrated body; a surface for guiding a workpiece is arranged in front of the protective cover, the surface having an arc shape and extending upwards with a long front part.
  • This type of protective cover is rather long, thus fully occupying the table for placing the workpiece due to the long shape of table cutting type protective cover.
  • the workpiece cannot be put on the table for operation, leading to much inconvenience.
  • the automatic opening of the protective cover is not very sensitive. Therefore, it is necessary to improve the prior art protective covers.
  • the present disclosure aims at providing a new table-cutting type protective cover for a composite saw.
  • the new protective cover can not only prevent the saw blade from being exposed thus ensuring the safety of the saw, it is also easy to use, occupies a small space and opens well. More importantly, the new protective cover can reserve space for accommodating the workpiece to be machined on the table so that the workpiece can be operated directly on the table.
  • a table-cutting type protective cover for a composite saw comprising a follower plate, a left and right auxiliary cover plate, and a movable cover body, wherein the follower plate and the movable cover body are respectively hinged to the two ends of the left and right auxiliary cover plate.
  • the left and right auxiliary cover plate may comprise a left cover plate and a right cover plate which together form the left and right auxiliary cover plate through splicing.
  • a torsional spring for driving the movable cover body to automatically restore it to its original position may be arranged at the hinge connecting the left and right auxiliary cover plate and the movable cover body.
  • a supporting part may be set at the bottom of the left and right auxiliary cover plate.
  • the top of the movable cover body may be hinged onto the left and right auxiliary cover plate, a supporting surface may be set at the bottom of the movable cover body, and a surface for withstanding the workpiece may be set at an outer surface of the movable cover body.
  • the new protective cover of the present disclosure provides the following advantages: It can prevent the saw blade from being exposed and thus improve the safety of the saw. It has a simple structure, requires low cost, and is convenient to assemble and disassemble. It occupies a small space, is flexible, and reserves more space for placing the workpiece to be machined. More importantly, it can reserve sufficient space for accommodating the workpiece to be machined on the table so that the workpiece can be directly operated on the table.
  • the present disclosure relates to composite saws, and particularly to a table-cutting type protective cover for a composite saw.
  • FIG. 1 is a schematic diagram of the new protective cover when in use
  • FIG. 2 is another schematic diagram of the new protective cover when in use.
  • the present disclosure relates to composite saws, and particularly to a table-cutting type protective cover for a composite saw.
  • a table cutting type protective cover for a composite saw comprises a follower plate 4, a left and right auxiliary cover plate 5 and a movable cover body 6, wherein the follower plate 4 and the movable cover body 6 are respectively hinged to the two ends of the left and right auxiliary cover plate 5.
  • the left and right auxiliary cover plate 5 comprises a left cover plate and a right cover plate which together form the left and right auxiliary cover plate 5 through splicing.
  • a torsional spring for driving the movable cover body 6 to automatically restore the movable cover body to its original position is arranged at the hinge connecting the left and right auxiliary cover plate 5 and the movable cover body 6.
  • a supporting part 7 is set at the bottom of the left and right auxiliary cover plate 5.
  • the top of the movable cover body 6 is hinged onto the left and right auxiliary cover plate 5, a supporting surface is set at the bottom of the movable cover body 6 and a workpiece withstanding surface 9 is set at an outer surface of the movable cover body 6.
  • the table cutting type protective cover can prevent the saw blade from being exposed and thus improve the safety of the saw. It has a simple structure, requires low cost, and is convenient to assemble and disassemble. It occupies a small space, is flexible, and reserves more space for placing the workpiece to be machined. More importantly, it can reserve sufficient space for accommodating the workpiece to be machined on the table so that the workpiece can be directly operated on the table.
  • the working principle of the protective cover of the present disclosure can be further illustrated hereinafter by referring to the use thereof on a composite saw:
  • the composite saw with a table cutting type protective cover comprises a base 10, a panel assembly 1, a frame 2, a saw blade 3 and a table cutting type protective cover, wherein the frame 2 is fixed or hinged onto the base 10, the angle of the frame 2 relative to the base 10 is adjustable and changeable, the panel assembly 1 is fixed onto the frame 2, the saw blade 3 is fixed onto the frame 2 through a bearing seat and can be driven by a driving device into rotation, an opening for the saw blade is provided on the panel assembly 1, an upper part of the saw blade 3 extends from the panel assembly 1 through the opening to the upper surface of the panel assembly 1, and the table cutting type protective cover is mounted on the upper surface of the panel assembly 1. A lower part of the saw blade 3 is exposed on the lower surface of the panel assembly 1.
  • the composite saw can switch between using the upper part and the lower part of the saw blade 3.
  • the workpiece When the composite saw is in use, the workpiece is placed on the upper surface of the panel assembly 1, and it is pushed towards the saw blade 3 (as shown in FIG. 2 , the workpiece is pushed leftwards), then the front end of the workpiece pushes against the withstanding surface of the movable cover body 6.
  • the workpiece pushes the movable cover body 6 to enable the movable cover body 6 to rotate around the hinge point of a first end, and in turn to enable the movable cover body 6 to rotate towards the inner cavity of the left and right auxiliary cover plate 5.
  • the movable cover body 6 With the forwarding of the workpiece, the movable cover body 6 pushes the left and right auxiliary cover plate 5 open to thus enable the left and right auxiliary cover plate 5 to rotate around the hinge point of the first end.
  • the workpiece contacts the saw blade 3 which then cuts the workpiece.
  • the panel assembly 1, the frame 2, and the saw blade 3 have been widely used. Their structures and principles are the same as those in the prior art, thus a detailed description of these parts is not necessary.
