[0026] The positioning assembly 400 in this embodiment is a structure for positioning the automobile cushion.
[0027] As shown in Figure 1 and Figure 2 , the positioning assembly 400 includes two slide rods 401 fixedly installed between the front and rear inner side walls of the box 1 and symmetrically distributed left and right. The outer side of the slide rod 401 is slidingly connected with a sliding block 402. The top of the sliding block 402 is fixedly installed with a T-shaped mounting plate 403. The top of the T-shaped mounting plate 403 is fixedly installed with an electric push rod 404. The top end of the electric push rod 404 is fixedly connected with a lifting column 405. The top of the two lifting columns 405 is fixedly installed with a lifting plate 406. The bottom of the lifting plate 406 is fixedly installed with a positioning rod 407. The bottom end of the positioning rod 407 is fixedly connected with a positioning block 408.
[0028] It should be noted that the bottom end of the T-shaped mounting plate 403 penetrates through the box 1 and extends to the center of the top of the sliding block 402. The top of the box 1 is provided with a sliding hole for the front and rear movement of the T-shaped mounting plate 403, which is used to facilitate the front and rear movement of the electric push rod 404 driven by the sliding block 402 through the T-shaped mounting plate 403.
[0029] The moving assembly 500 in this embodiment is a structure for driving the positioning mechanism and the automobile cushion to move forward and backward.
[0030] As shown in Figure 1 , Figure 3 and Figure 4As shown, the moving component 500 includes a servo motor 501 fixedly installed on the right side wall inside the housing 1. A rotating rod 502 is fixedly installed on the output shaft of the servo motor 501. Two first bevel gears 503 are fixedly installed on the outer side of the rotating rod 502. A second bevel gear 504 meshes with the back of the first bevel gears 503. A rotating screw 505 is fixedly connected to the back of the second bevel gear 504. A moving block 506 is threadedly connected to the outer side of the rotating screw 505. A support block 507 is fixedly installed on the top of the moving block 506. A moving plate 508 is fixedly installed between the tops of the two support blocks 507.
[0031] Understandably, the left end of the rotating rod 502 is rotatably connected to the housing 1 via a bearing to make the rotation of the rotating rod 502 more stable. The end of the rotating screw 505 away from the second bevel gear 504 is rotatably connected to the housing 1 via a bearing to make the rotation of the rotating screw 505 more stable. A fixing plate is fixedly installed between the front and rear inner side walls of the housing 1, and a support pad is fixedly installed on the top of the fixing plate. The support pad is rotatably connected to the rotating screw 505 via a bearing to enhance the stability of the rotation of the rotating screw 505.
[0032] It should be noted that the bottom end of the support block 507 passes through the housing 1 and extends to the center of the top of the movable block 506. The top of the housing 1 is provided with a movable hole for the support block 507 to move back and forth. This is to facilitate the movable block 506 to move the car seat cushion back and forth through the support block 507 and the movable plate 508. The height of the movable plate 508 is the same as the height of the edge pad 3, which is to facilitate the edge sewing machine body 2 to perform edge sewing on the car seat cushion.
[0033] It should be further explained that the positioning block 408 is located above the top of the moving plate 508, which is to facilitate the better clamping and fixing of the car seat cushion by the moving plate 508 and the positioning block 408. The bottom of the moving block 506 slides against the fixing plate to ensure that the moving block 506 will not rotate with the rotating screw 505, so that the moving block 506 can move back and forth on the rotating screw 505.
[0034] The working principle of the above embodiments is as follows:
[0035] (1) When it is necessary to position the car seat cushion, place the side of the car seat cushion that needs to be sewn on the sewing pad 3 and the other side on the moving plate 508. Then start the electric push rod 404. The electric push rod 404 drives the lifting plate 406 to move up and down through the lifting column 405. The lifting plate 406 drives the positioning block 408 to move up and down through the positioning rod 407, so that the positioning block 408 squeezes the car seat cushion. The car seat cushion is fixed under the squeezing force of the moving plate 508 and the positioning block 408, and the positioning process of the car seat cushion can be completed.
[0036] (2) when the automobile seat cushion needs to be edge stitched, the servo motor 501 and the edge stitching machine body 2 are started, the servo motor 501 drives the first bevel gear 503 to rotate through the rotating rod 502, the first bevel gear 503 drives the rotating screw 505 to rotate through the meshing second bevel gear 504, since the bottom of the moving block 506 is in close sliding fit with the fixed plate, the moving block 506 will not rotate with the rotating screw 505, so that the moving block 506 only moves forward and backward on the rotating screw 505 under the rotating thrust of the inner thread, so that the moving block 506 drives the moving plate 508 to move forward and backward through the supporting block 507, and then the automobile seat cushion moves forward and backward under the extrusion force of the moving plate 508 and the positioning block 408, thereby driving the positioning block 408 to move forward and backward, and at the same time, the sliding block 402 moves forward and backward on the outside of the sliding rod 401, so that the automobile seat cushion can be kept positioned at all times, and the edge stitching of the automobile seat cushion can be completed under the operation of the edge stitching machine body 2.
[0037] Compared with the prior art, the edge stitching machine positioning mechanism can position the automobile seat cushion through the cooperation of the positioning assembly 400 and the moving assembly 500 on the box body 1, ensure the uniformity of the edge stitching, reduce the labor intensity of the workers through manual positioning, and the positioning mechanism can move synchronously with the automobile seat cushion, so that the automobile seat cushion can be kept positioned at all times, and the automobile seat cushion can be moved forward and backward, reducing the labor intensity of manually moving the automobile seat cushion for edge stitching, further improving the edge stitching effect and efficiency of the automobile seat cushion, better meeting the actual use requirements of people, effectively improving the use effect and practicality of the existing edge stitching machine, and solving the problem that the existing edge stitching machine is inconvenient to position the automobile seat cushion.
[0038] The electrical components in the present application are electrically connected with the main controller and the power supply. The main controller can be a conventional known device such as a computer, and the existing disclosed power connection technology and power supply also belong to the common knowledge in the art, so the present application will not be described in detail.
