[0005] A further improvement is that the positioning device comprises a positioning piece placed in the first sewing hole and having a size close to the first sewing hole, and a protrusion block arranged on the positioning piece and matching the hole position of the sewn component.

[0006] A further improvement is that a center device for further improving the center positioning accuracy is also provided on the bottom plate.

[0007] A further improvement is that the central device comprises a positioning plate which is flippably arranged on the bottom plate, and a positioning hole which is provided on the positioning plate and matches the protruding block.

[0008] A further improvement is that an alignment device is also provided on the bottom plate to facilitate rapid positioning.

[0009] A further improvement is that the alignment device comprises a plurality of alignment blocks which are arranged on the bottom plate and match the shape of the edge of the upper.

[0010] A further improvement is that the alignment block is provided with a plurality of positioning grooves which match the protrusions on the upper and are used to improve the positioning accuracy.

[0011] A further improvement is that the fixing device comprises: a clamping hole provided on the pressing plate, and a clamping block rotatably arranged on the bottom plate for clamping with the clamping hole.

[0012] A further improvement is that: a heightening frame is further arranged on the bottom plate, the first sewing hole is located inside the heightening frame, and the pressing plate can be flipped and arranged on the heightening frame.

[0013] The advantages and beneficial effects of the utility model are:

[0014] The structure is simple and easy to use. The sewn parts and the upper are positioned by the clamp, so that the relative positions of the sewn parts and the upper are fixed and the positioning is accurate. The production personnel only need to sew along the gaps of the holes to accurately sew the upper and the parts together, which greatly reduces the production difficulty, improves the processing accuracy, has stable quality and high production efficiency.

DETAILED DESCRIPTION

[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] like Figure 1-Figure 4As shown, a sports shoe hollowing precision positioning sewing device comprises a bottom plate 1, a pressing plate 2 which is flippably arranged on the bottom, a fixing device is arranged between the pressing plate 2 and the bottom, a plurality of first sewing holes 3 which match the sewing lines are opened on the bottom plate 1, a second sewing hole 4 which corresponds to the first sewing holes 3 is opened on the pressing plate 2, and a positioning device for positioning the upper and the sewn parts is also arranged between the pressing plate 2 and the bottom plate 1.

[0022] In order to facilitate the positioning of the upper and the sewn component, the positioning device includes: a positioning piece 5, which is placed in the first sewing hole 3 and has a size similar to the first sewing hole 3, and a protrusion 6 arranged on the positioning piece 5 and matching the hole position of the sewn component.

[0023] In order to further improve the concentricity between the sewn parts and the holes of the upper, a center device for further improving the center positioning is also provided on the base plate 1, and the center device includes: a positioning plate 7 that can be flipped on the base plate 1, and a positioning hole 8 opened on the positioning plate 7 and matching the protrusion block 6.

[0024] In order to further improve the concentricity between the sewn parts and the holes of the upper, an alignment device for quick positioning is also provided on the base plate 1, and the alignment device includes: a plurality of alignment blocks 9 arranged on the base plate 1 and matching the edge shape of the upper, and the alignment blocks 9 are also provided with a plurality of positioning grooves 13 matching the protrusions on the upper for improving positioning accuracy.
