Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking equipment, in particular to a computer sewing machine template rapid replacement device. Background Art

[0002] Computer sewing machines (computer pattern machines) need to cooperate with templates to turn materials. Different products require different templates. The template is connected to the XY moving axis of the computer sewing machine, the cutting piece is fixed on the template, and the shape to be turned is hollowed out. In this way, different shapes can be accurately turned on the material. However, the existing templates are generally directly connected to the moving axis of the computer sewing machine through bolts and nuts. When replacing the template, workers or special mechanics need to use wrenches to replace it, which will affect work efficiency. Direct use of bolts to connect may cause the model position on the template to need to be fine-tuned. Some materials will be scrapped during the adjustment process, increasing production costs. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A device for quickly replacing templates for a computer sewing machine, comprising a moving shaft of a computer sewing machine and a template; a mounting plate is fixedly connected to the moving shaft of the computer sewing machine via a bolt and nut assembly, and a plurality of connecting holes are evenly distributed on the mounting plate, which are used to cooperate with the bolt and nut assembly to connect with the moving shaft of the computer sewing machine; a connecting plate is provided on the template, and positioning bosses are symmetrically provided at both ends of the connecting plate, and the positioning bosses pass through the positioning holes provided at both ends of the mounting plate, which are used to start the positioning effect on the template, and a rotating clamping plate is provided on the top of the positioning boss, which is used to fix the connecting plate on the mounting plate.

[0006] Preferably, a positioning frame is provided on the mounting plate, the inner shape of which matches the outer shape of the moving axis of the computer sewing machine, and is used for positioning and installing the mounting plate.

[0007] Preferably, the rotating clamping plate is connected to the positioning boss via a bolt and nut assembly, so that the rotating clamping plate can rotate and is firmly connected.

[0008] Preferably, the connecting plate and the template are bonded by glue or tape, or riveted by rivets, or are integrally formed.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: compared with the prior art method of directly connecting the template and the moving shaft of the computer sewing machine through a bolt and nut assembly, the installation and replacement of the template does not require the use of a wrench to turn the bolts and nuts, thereby improving work efficiency and reducing the workload of workers; and the connection method of the utility model does not require fine-tuning of the template, which can save materials.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figures 2 to 4As shown, the embodiment of the utility model includes a computer sewing machine moving shaft 1 and a template 2; the computer sewing machine moving shaft 1 is fixedly connected with a mounting plate 4 through a bolt and nut assembly 3, and a plurality of connecting holes 403 are evenly distributed on the mounting plate 4, which are used to cooperate with the bolt and nut assembly 3 to connect with the computer sewing machine moving shaft 1; a connecting plate 5 is arranged on the template 2, and positioning bosses 501 are symmetrically arranged at both ends of the connecting plate 5, and the positioning bosses 501 pass through the positioning holes 402 arranged at both ends of the mounting plate 4, which are used to start the positioning effect on the template 2, and a rotating clamping plate 502 is arranged on the top of the positioning boss 501, which is used to fix the connecting plate 5 on the mounting plate 4.

[0019] like Figure 2 and Figure 3 As shown, a positioning frame 401 is provided on the mounting plate 4, and its inner shape matches the outer shape of the moving shaft 1 of the computer sewing machine, and is used to position and install the mounting plate 4; Figure 4 As shown, the rotating clamping plate 502 is connected to the positioning boss 501 through a bolt and nut assembly, so that the rotating clamping plate 502 can rotate and is firmly connected.

[0020] like Figure 2-4 As shown, first place the mounting plate 4 under the moving shaft 1 of the computer sewing machine. The positioning frame 401 makes the mounting plate 4 accurately installed. The bolt and nut assembly 3 can accurately pass through the positioning hole 402 and the connecting hole 403 on the moving shaft 1 of the computer sewing machine, so that the mounting plate 4 is fixedly connected to the moving shaft 1 of the computer sewing machine; then connect the connecting plate 5 fixed to the template 2 with the mounting plate 4, and the positioning boss 501 is inserted into the positioning hole 402, so that the template 2 can be positioned, and there is no need to adjust the position of the template 2.
