DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to specific embodiments, but the protection scope of the present invention is not limited thereto.

[0032] Note: The embodiment of the present utility model describes the spatial position relationship of each part when the bolster is placed horizontally.

[0033] refer to Figures 1 to 3 The embodiment of the present utility model provides a bolster flexible positioning and marking device, comprising:

[0034] Positioning seat 1, in the shape of a flat plate;

[0035] The support rod 4 is vertically fixed to the middle of the top surface of the positioning seat 1;

[0036] The crossbeam 5 is fixed to the top of the support rod 4 and extends in a direction parallel to the positioning seat 1;

[0037] The slide 3 surrounds the support rod 4 and is loosely fitted with the support rod 4. The slide 3 can move along the length of the support rod 4 and can rotate around the support rod 4.

[0038] A plurality of positioning plates 2 are fixed to the outer circumference of the slide 3 at intervals, have the same shape and size, extend radially along the slide 3, and have their free ends monotonically moving away from the slide 3 along the direction of the positioning seat 1 pointing to the crossbeam 5. If any positioning plate 2 is rotated about the center line of the slide 3 as the axis, it will coincide with the other positioning plates 2.

[0039] The longitudinal beam (composed of a longitudinal rod 6 and a slide rod 7 in this embodiment) is fixed to the cross beam 5 and extends in a direction away from the cross beam 5 and parallel to the positioning seat 1 (in this embodiment, the longitudinal beam is perpendicular to the cross beam 5), with the end close to the cross beam 5 being the first end and the end away from the cross beam 5 being the second end;

[0040] The marking plates (in this embodiment, the first marking plate 8, the second marking plate 9, and the third marking plate 10) have a through hole at one end and are sleeved on the longitudinal beam. The other end extends along the cross beam 5 in the direction of the positioning seat 1 (extending downward when in use). The marking plates can move along the extension direction of the longitudinal beam and cannot rotate around the longitudinal beam. One long side is used for positioning and marking.

[0041] The baffle 11 is fixed to the second end of the longitudinal beam and is used to limit the extreme position of the movement of the marking plate.

[0042] Combine Figures 4 to 7 The present invention also provides a method for marking and positioning using the above-mentioned device, comprising:

[0043] Place the positioning seat 1 in the middle of the bottom plane 101 of the bolster core plate, covering the center hole 100 of the core plate;

[0044] Rotate and move the slide 3 so that each positioning plate 2 overlaps the top of the inner circumference 102 of the core plate so that the positioning seat 1 is close to the center of the bottom plane 101 of the core plate;

[0045] Move the marking plate horizontally and rotate the positioning base 1 so that the marking plate is in close contact with the marking surface 103 of the bolster, and mark the bolster along the long side of the marking plate for marking.

[0046] Even if the bolster core plate has a large diameter tolerance, by moving and rotating the slide 3, the positioning plates 2 can be moved and rotated. When each positioning plate 2 overlaps the top of the core plate inner circumference 102, the center of the slide 3 can be ensured to be aligned with the center of the bolster center hole. This ensures that the bolster flexible positioning and marking device is placed in the correct reference position, and the orientation of the bolster flexible positioning and marking device is precisely controlled. The word "flexible" indicates the device's flexibility and adaptability.

[0047] The marking surface 103 in the present invention is a surface perpendicular to the plane of the bolster and parallel to the longitudinal direction of the bolster. If the crossbeam 5 is not strictly parallel to the longitudinal direction of the bolster, the marking plate and the marking surface 103 may not fit tightly together. The operator can then rotate the positioning base 1 appropriately (for example, by rotating the crossbeam 5) to ensure that the marking plate and the marking surface 103 fit tightly together, thereby ensuring that the crossbeam 5 is strictly parallel to the longitudinal direction of the bolster.

[0048] By adopting the device and method provided by the utility model, the bolster has strong adaptability to the dimensional tolerance of the bolster when marking the bolster, is easy to operate, saves time and is highly efficient, and the marking position is accurate and reliable.

[0050] Optionally, the end opening of the scoring plate is polygonal, and the section of the longitudinal beam away from the cross beam 5 is gap-fitted with the scoring plate.

[0051] refer to Figure 1, the opening on the upper end of the scoring plate is a rectangular hole. In other embodiments, the opening on the upper end of the scoring plate can also be other polygonal shapes such as a triangle or a trapezoid.

[0052] Such a design can prevent the scribing plate from rotating around the crossbeam 5 .

The first end of the longitudinal rod 6 is the first end of the longitudinal beam, the second end of the longitudinal rod 6 is connected to the first end of the sliding rod 7, the second end of the sliding rod 7 is the second end of the longitudinal beam, and the sliding rod 7 is clearance-matched with the marking plate.

[0054] The marking plate and the slide rail 7 may also be matched in other ways such as slide rail matching.

[0055] In this embodiment, the slide bar 7 is welded to the end of the longitudinal bar 6. In other embodiments, the longitudinal beam is an integral structure. The longitudinal bar 6 and the slide bar 7 have equal or unequal diameters.

[0056] Optionally, the slide cylinder 3 is a cylinder, and the support rod 4 is a cylindrical rod.

[0057] Optionally, the positioning plate 2 is perpendicular to the positioning seat 1 and is a trapezoidal plate. In this case, the positioning plate 2 can be designed to be relatively thin. In other embodiments, the positioning plate 2 is a thick plate and is parallel to the positioning seat 1.

[0058] Optionally, the positioning plates 2 are evenly distributed around the slide 3. Figure 2 , the dihedral angle between two adjacent positioning plates 2 is 90°. The number of positioning plates 2 can also be 3 or 5 or more.

[0059] Optionally, refer to Figure 2 The number of longitudinal beams is multiple, and the number of the marking plates and the baffles 11 are both multiple and are arranged in one-to-one correspondence with the longitudinal beams.

[0060] In some other embodiments, the number of the longitudinal beam is one.

[0061] Optionally, the longitudinal beams are distributed on the same side of the cross beam 5 (eg Figure 2 shown) or distributed on both sides of the beam 5.

[0062] Optionally, refer to Figure 1 A groove is provided on the long side of the marking plate that is not used for marking. The groove is used to prevent the operator from selecting the wrong long side for marking.

[0063] By adopting the device and method provided by the utility model, the bolster has strong adaptability to the dimensional tolerance of the bolster when marking the bolster, is easy to operate, and the marking position is accurate and reliable.

[0064] The various embodiments of the present invention are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0065] The scope of protection of the present invention is not limited to the above-described embodiments. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the scope and spirit of the present invention.
