Description

Technical Field

[0001] The utility model relates to the technical field of flexible shaft processing, in particular to a flocking device used for flexible shaft processing. Background Art

[0002] In the field of automobiles or other mechanical equipment, flexible shafts are often used to transmit torque. In order to prevent the gap between the square head of the flexible shaft and the square hole of the coupling in the engine or output device from being too large, it is necessary to flock the surface of the flexible shaft. There are two main existing flocking methods. One is to heat the wool thread after winding it around the periphery of the flexible shaft to make the wool thread adhere to the periphery of the flexible shaft. The other is to apply a mixture of wool and flocking glue on the periphery of the flexible shaft, and then heat and cure the mixture of wool and flocking glue to form a flocking layer on the periphery of the flexible shaft.

[0003] For example, a Chinese patent document with publication number CN210257311U discloses a processing equipment for flocking a flexible shaft, including a flexible shaft to be flocked, a first silo, a heating device and a second silo. A first I-shaped wheel is provided in the first silo, on which a wound solid silk thread is provided. A second I-shaped wheel is provided in the second silo, on which a wound wool thread is provided. The flexible shaft is pulled through the first silo, the heating device and the second silo in sequence.

[0004] It can be seen from the above disclosed content that in the above technical scheme, by heating the solid silk thread, the heated solid silk thread can bond the wool thread and the soft shaft, and the produced flocked soft shaft is of high quality and the wool thread is not damaged. However, only a single soft shaft can be flocked one by one during flocking, so the overall flocking efficiency can be further improved. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a flocking device for flexible shaft processing, which can perform batch flocking on flexible shafts and improve the overall flocking efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flocking device for flexible shaft processing, comprising a heating furnace, a heating chamber is provided in the heating furnace, a support frame for placing the flexible shaft is provided in the heating chamber, the support frame comprises a base, a top tray and a bottom tray for placing the flexible shaft are provided on the base, the top tray and the bottom tray are symmetrically arranged, a top clip is provided on the top tray, and the top clips are multiple and spaced apart from each other, a bottom clip is provided on the bottom tray, and the bottom clips are multiple and spaced apart from each other, and the base can slide in or out of the heating chamber.

[0007] The utility model is further configured as follows: a symmetrical slide rail is provided in the heating chamber, a first sliding block opposite to the slide rail is provided at the bottom of the base, the first sliding block is coupled to the slide rail and can form a sliding fit between the two, and a handle is provided on one side of the base.

[0008] The utility model is further configured as follows: the base is connected to a bidirectional lead screw in a horizontal direction, and both ends of the bidirectional lead screw are respectively provided with a movable seat that forms a threaded fit with the two ends of the bidirectional lead screw, and the top and bottom of the movable seat respectively extend outward as a top connecting end and a bottom connecting end, and a guide groove is provided on the base, and a guide block extending toward the guide groove is provided at the bottom connecting end, and the guide block is coupled to the guide groove and can form a sliding fit between the two.

[0009] The utility model is further configured as follows: the top tray is fixed to the top connecting end, a slide groove is provided on the bottom connecting end, the bottom tray is provided with a second sliding block extending toward the slide groove, and the second sliding block is coupled to the slide groove and can form a sliding fit between the two.

[0010] The utility model is further configured as follows: the top bayonet and the bottom bayonet are arranged staggered with each other.

[0011] The utility model is further configured as follows: a spacing is left between the top tray and the bottom tray and the bidirectional lead screw.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting a top tray and a bottom tray, a double-layer structure can be formed, and the top tray and the bottom tray are respectively provided with multiple top snap-ins and bottom snap-ins. By snapping the two ends of the flexible shaft into the top snap-ins or the bottom snap-ins, the flexible shaft can be clamped and limited, so that multiple flexible shafts can be placed on the support frame.

[0017] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, the utility model discloses a flocking device for processing a flexible shaft, comprising a heating furnace 1, a heating chamber 101 is arranged in the heating furnace 1, a support frame 2 for placing the flexible shaft is arranged in the heating chamber 101, the support frame 2 comprises a base 21, a top tray 22 and a bottom tray 23 for placing the flexible shaft are arranged on the base 21, the top tray 22 and the bottom tray 23 are symmetrically arranged, a top bayonet 221 is arranged on the top tray 22, and the top bayonet 221 is multiple and spaced apart from each other, a bottom bayonet 231 is arranged on the bottom tray 23, and the bottom bayonet 231 is multiple and spaced apart from each other, the base 21 can slide into or out of the heating chamber 101, and a double-layer structure can be formed by arranging the top tray 22 and the bottom tray 23, and the top tray 22 and the bottom tray 23 are respectively provided with multiple top bayonet 221 and bottom bayonet 23. 231. After the fluff and flocking glue mixture is applied to the flexible shaft, the two ends of the flexible shaft are inserted into the top snap-in 221 or the bottom snap-in 231 to achieve clamping and limiting of the flexible shaft, so that multiple flexible shafts can be placed on the support frame 2. In this way, multiple flexible shafts can be heated and cured at the same time, so that the fluff and flocking glue mixture applied on the surface of the flexible shaft can form a flocking layer on the surface of the flexible shaft, and then the flexible shaft can be flocked in batches to improve the overall flocking efficiency. When the flexible shaft is placed in the top tray 22 and the bottom tray 23, or when the flexible shaft is removed from the top tray 22 and the bottom tray 23, the top tray 22 and the bottom tray 23 are driven to slide out of the heating chamber 101 by the slidable base 21, so that the placement of the flexible shaft is more convenient, wherein the heating furnace 1 can adopt conventional technology, such as an infrared heating furnace, an electric heating wire heating furnace, etc.

[0020] In the present embodiment, the sliding structure of the base 21 is that a symmetrical slide rail 3 is provided in the heating chamber 101, and a first slider 4 opposite to the slide rail 3 is provided at the bottom of the base 21. The first slider 4 is coupled to the slide rail 3 and can form a sliding fit between the two. A handle 7 is provided on one side of the base 21. By pulling the base 21, the first slider 4 and the slide rail 3 can form a sliding fit, thereby driving the top tray 22 and the bottom tray 23 to slide in or out of the heating chamber 101, and the handle 7 can be used to apply force, thereby facilitating the pulling of the base 21 to slide.

[0021] In this embodiment, the base 21 is connected to a bidirectional lead screw 5 in a horizontal rotation direction, and the two ends of the bidirectional lead screw 5 are respectively provided with a movable seat 6 that is threadedly matched with the two ends of the bidirectional lead screw 5. The top and bottom of the movable seat 6 extend outward as a top connection end 61 and a bottom connection end 62, respectively. The base 21 is provided with a guide groove 211, and the bottom connection end 62 is provided with a guide block 63 extending toward the guide groove 211. The guide block 63 is coupled to the guide groove 211 and can form a sliding fit between the two. Since the length of the soft shaft to be flocked is not the same during actual use Therefore, by setting the bidirectional screw 5, the moving seats 6 on both sides can be moved toward or away from each other by rotating the bidirectional screw 5, so as to adjust the distance between the adjacent top trays 22 and the adjacent bottom trays 23, so as to adapt to flexible shafts of different lengths and expand the scope of application. When the bidirectional screw 5 is rotated, the guide block 63 can slide along the guide groove 211, so as to guide the moving path of the moving seat 6, prevent the moving seat 6 from rotating with the rotation of the bidirectional screw 5, and ensure the stability of the movement of the moving seat 6.

[0022] In addition, the top tray 22 is fixed to the top connecting end 61, and a slide groove 621 is provided on the bottom connecting end 62. The bottom tray 23 is provided with a second slider 232 extending toward the slide groove 621. The second slider 232 is coupled to the slide groove 621 and can constitute a sliding fit between the two. Therefore, the top tray 22 and the bottom tray 23 are respectively connected to the movable seat 6 through the top connecting end 61 and the bottom connecting end 62. In this way, by rotating the bidirectional lead screw 5, the spacing between adjacent top trays 22 and the spacing between bottom trays 23 can be adjusted at the same time to improve the adjustment efficiency. Moreover, by setting the second slider 232 and the slide groove 621, the bottom tray 23 can slide, so that it can be staggered with the top tray 22 to prevent the top tray 22 above the bottom tray 23 from interfering when the flexible shaft is placed in the bottom tray 23, thereby facilitating the placement of the flexible shaft into the bottom tray 23.

[0023] In this embodiment, the top snap-in 221 and the bottom snap-in 231 are staggered with each other, so that the flexible shaft inserted into the top snap-in 221 and the flexible shaft inserted into the bottom snap-in 231 can be staggered with each other, thereby preventing the mixed liquid of the fluff and flocking glue applied on the flexible shaft in the top tray 22 from dripping into the flexible shaft in the bottom tray 23 below, thereby affecting the uniformity of the flocking layer formed on the surface of the flexible shaft below;

[0024] In addition, there is a spacing between the top tray 22 and the bottom tray 23 and the bidirectional lead screw 5. Since the soft shaft is elastic, the soft shaft will sag when placed in the top tray 22 and the bottom tray 23. The spacing can prevent the sagged soft shaft from contacting the bidirectional lead screw 5 and affecting the formation of the flocking layer on the surface of the soft shaft.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
