Description

Technical Field

[0001] The utility model relates to the field of saw blade processing devices, in particular to a centering tool used for laser cutting of saw blade substrates. Background Art

[0002] As the core component of various saw blades (such as stone saw blades, metal saw blades, woodworking saw blades, etc.), the saw blade base has strict requirements on its processing accuracy. The saw blade base usually needs to be precisely processed to ensure its geometric shape, thickness uniformity and precise matching with the subsequently installed cutter head or teeth. Laser cutting, as an efficient and accurate non-contact thermal cutting technology, is widely used in the manufacturing process of saw blade bases to achieve complex shape cutting, hole opening, contour processing and other tasks.

[0003] In the laser cutting of saw blade base, the centering tool is particularly important, because the saw blade needs to rotate at high speed in actual use, which requires that the center hole of the base and the overall outer contour must be highly concentric to ensure smooth operation, reduce vibration, extend service life, and ensure cutting quality. Therefore, it is necessary to design a centering tool for laser cutting of saw blade base, which can be quickly fixed in the center of the saw blade base and provide precise positioning for laser cutting equipment to process the saw blade base.

DETAILED DESCRIPTION

[0020] like Figure 1 and Figure 2As shown, a centering tool for laser cutting of a saw blade base includes an alignment device 3. A center hole 2 is opened at the center position of the saw blade base 1. The alignment device 3 is mounted at the center hole 2 through a support rod 4. The alignment device 3 includes a top plate 301, a rotating disk 302 and an extended card plate 303. The extended card plate 303 is radially extended and retracted under the drive of the rotating disk 302. The extended card plate 303 abuts against the inner wall of the center hole 2 and keeps the position of the alignment device 3 fixed. During use, the device is firstly mounted at the center hole 2 of the saw blade base 1 through the support rod 4 to complete preliminary positioning. By extending the extended card plate 303 and fixing the position of the alignment device 3, precise positioning has been achieved. The axis of the saw blade base 1 can be quickly determined through the extended card plate 303, so that the cutting equipment and the saw blade base 1 can be quickly and accurately aligned.

[0021] The preferred solution is Figure 2 As shown, a vertical plate 11 is vertically arranged on the outer side of the rotating disk 302, and the other end of the vertical plate 11 is vertically clamped with the lower end surface of the top plate 301. The vertical plate 11 is movably connected to the lower end surface of the top plate 301 and can rotate freely around the axis of the top plate 301. A mounting hole 6 is opened at the axis of the top plate 301, and a boss 7 is correspondingly arranged at the axis of the rotating disk 302. The boss 7 passes through the mounting hole 6. The extended card plate 303 is installed between the top plate 301 and the rotating disk 302. The rotating boss 7 can drive the rotating disk 302 to rotate around its own axis, thereby driving the extended card plate 303 to extend and retract along the radial direction.

[0022] The preferred solution is Figure 3 As shown, a knob 8 is provided on the upper end surface of the boss 7, and the knob 8 is coaxial with the boss 7. A center scale bar 9 is engraved at the center position of the upper end surface of the knob 8. By rotating the knob 8, the boss 7 and the rotating disk 302 can be driven to rotate synchronously. When the position of the alignment device 3 is fixed, the axis of the saw blade base 1 (the center position of the center scale bar 9) can be quickly located through the center scale bar 9.

[0023] The preferred solution is Figure 4 and Figure 5 As shown, the upper end surface of the rotating disk 302 is provided with a volute tooth plate 10, and the volute tooth plate 10 is arranged around the boss 7. The volute tooth plate 10 is annularly symmetrically provided with an extension card plate 303, and the lower end surface of the extension card plate 303 is provided with an arc-shaped tooth plate 12 and meshed with the volute tooth plate 10. The rotating disk 302 drives the extension card plate 303 to slide forward and backward along the radial direction by rotating;

[0024] When the alignment device 3 is mounted on the center hole 2 of the saw blade base 1 through the support rod 4, the boss 7 and the rotating disk 302 can be driven to rotate synchronously by rotating the knob 8. The rotation of the rotating disk 302 drives the spiral tooth plate 10 to rotate synchronously, and then drives the expansion card plate 303 to slide radially outward until all the expansion card plates 303 are against the inner wall of the center hole 2. Because the expansion card plates 303 all slide synchronously and their positions are annularly symmetrical, when all the expansion card plates 303 are against the inner wall of the center hole 2, the position of the alignment device 3 remains fixed and coaxial with the saw blade base 1, and the center position of the center scale bar 9 is the axis of the saw blade base 1.

[0025] The preferred solution is Figure 6 As shown, connecting seats 5 are provided on both sides of the upper end surface of the top plate 301, and a socket 501 is opened on the connecting seat 5. The support rod 4 is plugged into the connecting seat 5 through the socket 501. When the device is used up, the support rod 4 can be pulled out to reduce the size of the device. The support rod 4 of a suitable length can be replaced according to the size of the center hole 2 to ensure that the alignment device 3 can be erected at the center hole 2.

Under the premise of non-conflict, the various technical features recorded in the utility model can be combined with each other. The protection scope of the utility model shall be the technical solution recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solution recorded in the claims.
