[0001] The utility model relates to the technical field of automobile processing tooling, in particular to an automobile spare tire cover plate edge binding mechanism. Background Art

[0002] A spare tire cover is a movable partition between the trunk and the spare tire compartment. It serves as both the cover and the floor of the compartment, primarily decorating the compartment, carrying items within, and covering the spare tire and onboard tools. Currently, the most commonly used spare tire cover is based on PHC board, with the front and sides of the PHC board covered in fabric.

[0003] Existing edging devices generally use a horizontal pushing plate structure for horizontal pushing operations. However, due to the certain thickness of the edging, the edging will be damaged when a horizontal hard pushing operation is adopted. In addition, the traditional edging device only uses a horizontal pushing mechanism to stick the felt cloth and the PHC board together. Since there is no corresponding re-pressing device, it is easy to cause the problem of loose adhesion. Therefore, the present application proposes an automobile spare tire cover edging mechanism to solve the above problems. Utility Model Content

As the edging pusher 3 moves toward the center position of the cover plate, the re-pressing roller 10 moves to the connection position between the cover plate and the felt cloth, and realizes the re-pressing operation under the action of the abutment spring 8, thereby ensuring that the edging between the felt cloth and the cover plate is more firm.

[0026] The depth adjustment mechanism includes an auxiliary frame 12, which is U-shaped and fixed to the lower end of the support platform 1. The left and right inner walls of the auxiliary frame 12 are respectively located in the same plane as the left and right inner walls of the operating hole 2. The left and right ends of the support base 5 are slidably connected to the left and right inner walls of the operating hole 2 and the left and right inner walls of the auxiliary frame 12 through limiting sliding grooves.

[0027] The lower end of the auxiliary frame 12 is fixedly connected to an adjusting motor 13, and the output end of the adjusting motor 13 is fixedly connected to an internally threaded adjusting cylinder 14, and the internally threaded adjusting cylinder 14 is internally threaded with an adjusting screw 15.

At the same time, after the hemming is completed, the supporting base plate 5 is pushed upward by cooperation between the adjusting motor 13, the internally threaded adjusting cylinder 14 and the adjusting screw 15, thereby facilitating the staff to take out the cover plate;

The infrared ranging device 19 is located directly above the supporting base plate 5. The infrared ranging device 20 is located directly above the support platform 1. The difference between the infrared ranging device 19 and the infrared ranging device 20 is the distance between the upper end surface of the supporting base plate 5 and the upper end surface of the support platform 1, that is, the depth of the operating hole 2.

[0029] The upper end of the top plate 16 is fixedly connected to a clamping cylinder 17, the output end of the clamping cylinder 17 passes through the top plate 16 and is fixedly connected to a connecting plate 18, a pressing plate 24 is provided below the connecting plate 18, the four corners of the upper end of the pressing plate 24 are fixedly connected to sliding rods 22, the upper end of the sliding rod 22 passes through the connecting plate 18 and is fixedly connected to a baffle 21, a buffer spring 23 is provided on the sliding rod 22, the upper end of the buffer spring 23 abuts against the lower end of the connecting plate 18, the lower end of the buffer spring 23 is fixedly connected to the upper end of the pressing plate 24, and a protective pad 25 is provided at the lower end of the pressing plate 24. The provision of the protective pad 25 ensures that the cover plate will not be damaged when the pressing plate 24 is used to clamp the cover plate.

[0030] Working principle: When in use, the size between the upper end surface of the support platform 1 and the upper end surface of the support base plate 5 is adjusted according to the cover plate to be wrapped and the thickness of the felt cloth. The adjusting motor 13 is turned on to drive the internal thread adjusting cylinder 14 to rotate. The internal thread adjusting cylinder 14 cooperates with the adjusting screw 15 to adjust the position of the support base plate 5 in the up and down directions. During the adjustment process, the infrared ranging device 19 and the infrared ranging device 20 respectively adjust the distance between the support base plate 5 and the upper end surface of the support platform 1 and the ranging device. The difference between the infrared ranging device 19 and the infrared ranging device 20 is the distance between the upper end surface of the support base plate 5 and the upper end surface of the support platform 1, which is the depth of the operating hole 2. When the depth of the operating hole 2 is adjusted appropriately, the felt cloth is placed on the bottom of the operating hole 2. The size of the felt cloth is larger than the size of the operating hole 2. The edge of the felt cloth covers the wrapping pusher 3. The adhesive material is applied on the felt cloth. The cover plate is then placed on the felt cloth, and the cover plate is located inside the operating hole 2. The pressing cylinder 17 is opened to push the connecting The connecting plate 18 and the pressing plate 24 move downward. When the pressing plate 24 contacts the cover plate, the connecting plate 18 continues to move downward, the sliding rod 22 slides relative to the connecting plate 18, and the connecting plate 18 compresses the buffer spring 23, thereby ensuring that the cover plate and the felt cloth are closely fitted and the adhesive is firmly attached. During the hemming operation, several driving cylinders 4 alternately push the hemming pusher 3 toward the cover plate. A contact arc surface 11 is provided on the side of the lower end of the hemming pusher 3 close to the cover plate, thereby ensuring that the felt cloth will not be damaged during the hemming process. Cause damage, as the edging pusher 3 moves toward the center of the cover plate, the re-pressing roller 10 moves to the connection position between the cover plate and the felt cloth, and realizes the re-pressing operation under the action of the abutment spring 8, thereby ensuring that the edging between the felt cloth and the cover plate is more firm. After the edging is completed, the support base plate 5 is pushed upward by adjusting the motor 13, the internal thread adjustment cylinder 14 and the adjustment screw 15, so that the staff can take out the cover plate. After the cover plate is taken out, the support base plate 5 is reset under the action of the adjustment motor 13, and the edging operation can be repeated.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
