[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Specific examples are given below.

[0031] See also Figure 1-Figure 5 , the utility model describes a connection assembly for a sewing machine and a servo motor, comprising a connection assembly 1, wherein the connection assembly 1 is arranged between a machine head 2 and a servo motor 3 for fixed assembly therebetween, the connection assembly 1 comprising a fixing seat 101 and a docking seat 102, the fixing seat 101 comprising a bottom plate 1011 and an adapter seat 1012, the outer shape of the bottom plate 1011 being adapted to fit the inner wall of the housing 4, the adapter seat 1012 being provided with a through hole 10121 docking with the protrusion 202 on the machine head 2, the size of the through hole 10121 being fine-tuned accordingly according to the size of the protrusion 202, the fixing seat 101 further comprising an assembly through hole 10122 located on the adapter seat 1012 and mating with the first fixing hole 201 on the machine head 2, the assembly through hole 10122 being provided with several groups of different specifications for adapting to a variety of different models of sewing machine heads 2;

[0032] The adapter seat 1012 is provided with a first break 10123 for fine-tuning the size of the through hole 10121, and the first break 10123 breaks the adapter seat 1012 into a C shape. The adapter seat 1012 is fixedly provided with fixing ears 10124 at both ends of the first break 10123, and the fixing ears 10124 are provided with screw holes 10125. The fixing seat 101, the docking seat 102, and the servo motor 3 are respectively provided with a first assembly seat 1013, a second assembly seat 1021, and a third assembly seat 301 for fixing and assembling the three. When the staff assembles the sewing machine, when the assembled sewing machine When the first fixing hole 201 for fixing the servo motor 3 is not provided on one side of the machine head 2, the staff first assembles and fixes the fixing seat 101, the docking seat 102, and the servo motor 3 with fixing bolts, and then aligns the through hole 10121 on the fixing seat 101 with the protrusion 202 on the machine head 2, and inserts the protrusion 202 into the through hole 10121. If the protrusion 202 is larger than the through hole 10121, the user can slightly bend the connecting component 1 to enlarge the aperture of the through hole 10121, so that the protrusion 202 can be inserted into it, and then the external fixing bolt is inserted into the screw hole 10125 and tightened to make the through hole 101 21 firmly holds the protrusion 202, so that the servo motor 3 is firmly assembled on the machine head 2. The connecting component 1 can install the servo motor 3 on the machine head 2 that is not provided with the first fixing hole 201. On the contrary, if the sewing machine to be installed is the opposite of the above-mentioned sewing machine, its protrusion 202 is slightly smaller than the through hole 10121, then it can be directly assembled and fixed. If it is too small compared to the through hole 10121, a gasket can be used to pre-sleeve the protrusion 202 to complete the subsequent assembly, which greatly improves the practicality and adaptability. There is another situation when assembling the sewing machine. A first fixing hole 201 for assembly is provided on one side of the machine head 2, but different models The first fixing hole 201 provided on the sewing machine has different distances from the aperture, which leads to very different specifications of connectors on the market. The adapter seat 1012 in the connecting component 1 of the utility model is provided with several groups of assembly through holes 10122 of different specifications, which can be adapted to the first fixing hole 201 on the sewing machine head 2 of various models. The staff can fix the connecting component 1 on the machine head 2 by inserting the fixing screw into the assembly through hole 10122 corresponding to the first fixing hole 201. Different models of machine heads 2 only need to correspond to the assembly through holes 10122 of the same specifications, which further improves the practicality and applicability of the connecting component 1.

[0033] Furthermore, the docking seat 102 is provided with a third break 1024 for its micro-deformation, and the third break 1024 is located on the same vertical line as the first break 10123 and the second break 101231; after the docking seat 102 is assembled with the fixed seat 101 and the servo motor 3, when the fixed seat 101 is fixed on the machine head 2, the third break 1024 can allow the docking seat 102 to deform accordingly according to the deformation of the fixed seat 101, to assist in adaptation.

[0034] Furthermore, the adapter seat 1012 is provided with a second break 101231 opposite to the first break 10123, and the angle of the second break 101231 is an arc chamfer; the bottom plate 1011 is provided with an arc groove 10111 for the bottom plate 1011 to slightly deform; when the size of the through hole 10121 does not match the size of the protrusion 202 and the size of the through hole 10121 needs to be adjusted, the first break 10123 and the second break 101231 allow the adapter seat 1012 to be slightly deformed within the allowable range to change the size of the through hole 10121, and the arc groove 101 The opening of 11 allows the base plate 1011 to deform accordingly, and since the inner angle of the second fracture 101231 is an arc-shaped chamfer, the arc-shaped groove 10111 is also an arc-shaped structure. When the above-mentioned adapter 1012 and the base plate 1011 are deformed, the arc-shaped structure makes its structure curved and soft, providing a smooth transition, which helps to disperse the stress generated during bending. In material mechanics, the arc-shaped structure greatly reduces the stress concentration effect during deformation, so that the stress can be distributed over a wider area instead of being concentrated at one point. Such a structural design greatly improves the structural strength and reliability of the fixing seat 101.

[0035] Furthermore, the adapter seat 1012 is provided with a fixing portion 10126 for fixing the fixing seat 101 to the protrusion 202 on the machine head 2. One side of the fixing portion 10126 is connected to the outside of the adapter seat 1012, and a fixing screw hole 10127 connected to the through hole 10121 is provided in the fixing portion 10126. When the adapter seat 1012 is assembled on the protrusion 202, the staff can insert the fixing screw into the fixing screw hole 10127 in the fixing portion 10126, and use a tool to continuously rotate the fixing screw and make one end of it press against the side of the protrusion 202, so as to further fix the adapter seat 1012, thereby ensuring the firmness of its fixed state and improving the practicality and applicability of the connecting component 1.

[0036] Furthermore, a positioning bar 10128 is fixedly provided on the assembly surface of the adapter seat 1012 and the docking seat 102, and a positioning groove 1022 is provided on the docking seat 102 to cooperate with the positioning bar 10128. When the fixed seat 101 and the docking seat 102 are assembled and fixed, the positioning bar 10128 is inserted into the positioning groove 1022 to limit the docking seat 102 and the fixed seat 101 so that their central axes always remain consistent, thereby ensuring stable and reliable assembly.

[0037] Furthermore, a positioning block 1023 for positioning with the external shell 4 is fixedly provided on the docking seat 102, and a second fixing hole 10231 for fixing with the shell 4 is opened on the positioning block 1023. In the final assembly work, the shell 4 needs to be mounted on the outside of the connecting component 1 and the servo motor 3. The inner wall of the shell 4 is provided with a positioning component for limiting the positioning block 1023 to ensure the firmness and accuracy of the shell 4 when it is mounted. Finally, the external fixing screw is inserted into the hole on the shell 4 and turned into the second fixing hole 10231 to complete the fixed assembly of the shell 4.

[0038] Furthermore, a plurality of reinforcing ribs 10129 are provided on the adapter seat 1012 , and the cooperation of the plurality of reinforcing ribs 10129 makes the structure of the adapter seat 1012 more tough and reliable.
