Specific implementation mode

[0023] The following will cooperate with the drawings and embodiments to detail the implementation mode of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying 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 to the present utility model.

[0025] Figures 1 - 3 This is an embodiment of the present utility model. The specific problem targeted by this specific embodiment is that the steering wheel cover sewing machine is a device specifically used for making vehicle steering wheel covers. The inventor found in the retrieval process that the Chinese patent application number 202221365426.3 discloses a steering wheel cover sewing machine. However, after understanding the solution, it is found that although the above-mentioned disclosed patent realizes the sewing work of the steering wheel cover, the mechanism structure for conveying the steering wheel leather material that needs to be sewn is relatively complex, and the manufacturing cost is relatively high. Moreover, during the edge sealing process, the edge of the leather material will curl. Without a corresponding pressing device, the situation of folded edge sewing will occur, and the usability is relatively poor. In response to the above existing problems, the inventor elaborated an automobile steering wheel cover processing and sewing device, in which the edge eaves pushing member 5 sliding on the top plate 4 spreads the edge eaves of the leather material through the edge spreading block 52 before the sewing machine head 6 intervenes, and the acting position of the sewing machine head 6 is between two edge spreading blocks 52. Therefore, during the sewing process of the leather material, it is always in a flat state, thus avoiding the situation of folded edges during the sewing process and enhancing the sewing effect.

[0026] A processing and sewing device for an automobile steering wheel cover described in this solution is specifically provided with a processing base 1, a processing backing plate 2 is arranged on the processing base 1, a support plate 3 is arranged at the upper end of the processing base 1, and a top plate 4 for cooperatively clamping leather materials with the processing backing plate 2 is arranged between the support plate 3 and the processing base 1. An edge eaves pushing member 5 is slidably installed on the top plate 4, and a sewing machine head 6 that moves synchronously with the edge eaves pushing member 5 is arranged on the support plate 3. The sewing machine head 6 is installed on the bottom surface of the support plate 3. Processing grooves 7 are opened on both the top plate 4 and the processing backing plate 2, and the processing grooves 7 penetrate through the processing backing plate 2 and the top plate 4. An extension groove 10 adapted to the processing groove 7 is opened on the support plate 3, and the opening positions of the extension groove 10 and the processing groove 7 are adapted. The support plate 3 and the processing backing plate 2 are connected by a telescopic column 9, and the sewing machine head 6 reciprocates left and right on the support plate 3 and extends downward into the extension groove 10. A processing cushion block 8 is arranged in the processing groove 7 of the processing backing plate 2. The processing cushion block 8 forms a working surface different from that of the processing backing plate 2 in this solution. The diameter of the processing cushion block 8 is set to be adapted to the width of the processing groove 7. The top surface of the processing cushion block 8 is arc-shaped, and the processing cushion block 8 is connected to the side wall of the processing backing plate 2 and the chamfer is rounded. The setting of the processing cushion block 8 can produce a guiding effect on the edge eaves pushing member 5, facilitating the interaction between the processing cushion block 8 and the edge eaves pushing member 5.

[0027] The edge eaves pushing member 5 includes a slide bar 51 installed in the processing groove 7 of the top plate 4. Slide grooves 11 are opened on the front and rear side walls of the processing groove 7 of the top plate 4. The slide bar 51 is placed inside the slide groove 11 and reciprocates along the slide groove 11. The movement of the slide bar 51 in the slide groove 11 is specifically realized by a linear slide rail in this embodiment. Two edge spreading blocks 52 are installed at both ends of the slide bar 51. The edge spreading block 52 includes an installation end 521 connected to the slide bar 51 and a docking end 522 connected to the installation end 521. The lower end surface of the docking end 522 is arc-shaped and is adapted to the upper end surface of the processing cushion block 8. The bottom surface of the docking end 522 protrudes from the bottom surface of the top plate 4. The bottom surface of the top plate 4 and the top surface of the processing backing plate 2 are both horizontal. The acting position of the sewing machine head 6 is located between the two edge spreading blocks 52. The support plate 3 is connected to the top plate 4 and moves synchronously. With the synchronous movement of the top plate 4 on the support rod, when the telescopic rod drives the top plate 4 and the support plate 3, the distance between the top plate 4 and the support rod can be gradually reduced, finally completing the clamping of the leather material in the vertical direction, and the two edge spreading blocks 52 flatten the edge eaves of the leather material, enhancing the stability of the leather material during the sewing process.

[0028] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art, and the present utility model mainly aims to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0029] It should be noted that in this text, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0030] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
