Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a fixing fixture for assisting in the winding of sandpaper and abrasive belt. Background Technology

[0002] In the sandpaper production process, sanding tape needs to be wrapped around the sandpaper for packaging and protection. Therefore, a fixed tool is needed to position the sanding tape so that workers can wrap the sanding tape around the sandpaper.

[0003] A sanding belt fixing fixture is a device used to position and support the sanding belt during installation, use, or replacement.

[0004] However, since different sizes of sandpaper require different sizes of sanding belts, existing methods can only fix sanding belts of specific sizes, which has certain limitations and inconveniences and needs to be improved.

[0005] Therefore, this utility model provides a fixing fixture for assisting in the winding of sandpaper and sanding belt, in order to solve the problems in the background art. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides a fixing fixture for assisting in the winding of sandpaper and abrasive belt, comprising: a threaded rod, an abrasive belt roller, and a fixing mechanism;

[0007] A sanding belt roller is fitted onto the threaded rod, and two fixing mechanisms are provided on the threaded rod, which are respectively connected to both ends of the sanding belt roller.

[0008] The fixing mechanism includes a housing, a connecting plate, a rotating shaft, a lever, a ball one, a ball two, a pressing plate, a plane bearing, and a conical tube. The threaded rod is fitted with two housings, each housing having a plane bearing fixedly mounted on one side. Each plane bearing has a conical tube fixedly connected to one side. Both conical tubes are fitted onto the threaded rod, with one end of each tube abutting against the sanding belt roller. Through the cooperative design between the threaded rod and the two fixing mechanisms, by sequentially installing the two fixing mechanisms and the sanding belt roller on the threaded rod and adjusting the distance between the two fixing mechanisms, it is possible to fix sanding belt rollers of different specifications, improving convenience and applicability. It also allows for fine-tuning of the distance between the two conical tubes, enhancing flexibility.

[0009] Preferably, the housing has two mounting slots symmetrically opposite each other, and a connecting plate is slidably installed in each of the two mounting slots. One end of each connecting plate is threadedly connected to the threaded rod. Through the threaded action between the two connecting plates and the threaded rod, the housing cannot move quickly on the threaded rod. At the same time, through the self-locking property of the threads between the connecting plates and the threaded rod, the housing can be limited.

[0010] Preferably, each of the two connecting plates has a second mounting groove on one side, and a ball is movably mounted in each of the two second mounting grooves for transmission.

[0011] Preferably, a rotating shaft is rotatably installed in each of the two mounting slots, and a lever is fixedly connected to each of the two rotating shafts. One end of each lever is fixedly connected to one of the two balls, which serve as levers and are used for direction-changing transmission.

[0012] Preferably, one end of each of the two levers is fixedly connected to a ball, and each of the two balls is movably connected to a pressing plate. Both pressing plates are slidably connected to the housing, which facilitates the adjustment of the two connecting plates by the operator.

[0013] Preferably, one end of each of the two connecting plates is threaded and adapted to the thread on the threaded rod, so as to facilitate threaded transmission between the two connecting plates and the threaded rod.

[0014] Preferably, torsion springs are fixedly sleeved at both ends of the two rotating shafts, and one end of each of the four torsion springs is fixedly connected to the housing. The elastic potential energy of the four torsion springs can restore the two connecting plates and the pressing plate to their original state.

[0015] Preferably, one end of the threaded rod is fixedly connected to a support rod for supporting the threaded rod, and one end of the support rod is fixedly connected to a mounting plate for facilitating the installation and fixing of the threaded rod.

[0016] Compared with related technologies, the fixing fixture for assisting in the winding of sandpaper and abrasive belt provided by this utility model has the following beneficial effects:

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1-4 A fixing fixture for assisting in the winding of sandpaper and abrasive belt includes: a threaded rod 1, an abrasive belt roller 2, and a fixing mechanism 3;

[0025] A sanding belt roller 2 is fitted onto the threaded rod 1, and two fixing mechanisms 3 are provided on the threaded rod 1. The two fixing mechanisms 3 are respectively connected to the two ends of the sanding belt roller 2.

[0026] The fixing mechanism 3 includes a housing 31, a connecting plate 32, a rotating shaft 33, a lever 34, a ball 1 35, a ball 2 36, a pressing plate 37, a flat bearing 38, and a conical tube 39. The threaded rod 1 is fitted with two housings 31. A flat bearing 38 is fixedly installed on one side of each of the two housings 31. A conical tube 39 is fixedly connected to one side of each of the two flat bearings 38. The two conical tubes 39 are fitted onto the threaded rod 1. One end of each conical tube abuts against the sanding roller 2. Through the cooperative design between the threaded rod 1 and the two fixing mechanisms 3, by sequentially installing the two fixing mechanisms 3 and the sanding roller 2 on the threaded rod 1 and adjusting the distance between the two fixing mechanisms 3, it is possible to fix sanding rollers 2 of different specifications, thereby improving convenience and applicability. It also allows for fine-tuning of the distance between the two conical tubes 39, improving flexibility.

[0027] In this method, two mounting slots are provided in the housing 31. The two mounting slots are symmetrical to each other. A connecting plate 32 is slidably installed in each of the two mounting slots. One end of each connecting plate 32 is threadedly connected to the threaded rod 1. Through the threaded action between the two connecting plates 32 and the threaded rod 1, the housing 31 cannot move quickly on the threaded rod 1. At the same time, through the self-locking property of the thread between the connecting plate 32 and the threaded rod 1, the housing 31 can be limited.

[0028] In this configuration, each of the two connecting plates 32 has a mounting groove 2 on one side, and a ball 35 is movably mounted in each of the two mounting grooves 2 for transmission. A rotating shaft 33 is rotatably mounted in each of the two mounting grooves 1, and torsion springs are fixedly sleeved at both ends of the two rotating shafts 33. One end of each of the four torsion springs is fixedly connected to the housing 31. The elastic potential energy of the four torsion springs can restore the two connecting plates 32 and the pressing plate 37 to their original state. A lever 34 is fixedly connected to each of the two rotating shafts 33, and one end of each lever 34 is fixedly connected to the two balls 35 respectively, which act as levers and are used for direction-changing transmission. A bearing 1 is fixedly mounted on each of the two rotating shafts 33, and its outer wall is fixedly connected to the housing 31.

[0029] In this configuration, one end of each of the two levers 34 is fixedly connected to a ball 36, and each of the two balls 36 is movably connected to a pressing plate 37. Both pressing plates 37 are slidably connected to the housing 31, which facilitates the adjustment of the two connecting plates 32 by the operator.

[0030] In this method, one end of each of the two connecting plates 32 is threaded and is adapted to the thread on the threaded rod 1, which facilitates the threaded transmission between the two connecting plates 32 and the threaded rod 1.

[0031] In this method, a support rod 4 is fixedly connected to one end of the threaded rod 1 to support the threaded rod 1, and a mounting plate 5 is fixedly connected to one end of the support rod 4 to facilitate the installation and fixation of the threaded rod 1.

[0032] The working principle of the fixing fixture for assisting in the winding of sandpaper and abrasive belt provided by this utility model is as follows:

[0033] In use, first install one of the two fixing mechanisms 3 on the threaded rod 1, then put the sanding belt roller 2 on the threaded rod 1 and put one end of it on the conical tube 39, then install the other fixing mechanism 3 on the threaded rod 1 and put the conical tube 39 in contact with the sanding belt roller 2, thereby achieving the effect of limiting and fixing the sanding belt roller 2.

[0034] During the installation of the fixing mechanism 3, firstly, press the pressing plates 37 on both sides of the housing 31 and slide them into the housing 31 a certain distance. At the same time, the two pressing plates 37 are driven by the cooperation of the two balls 36 and the lever 34, causing the two rotating shafts 33 to rotate a certain angle on the housing 31. At the same time, the four torsion springs are further charged. Meanwhile, the two levers 34 are driven by the two balls 35, causing the two connecting plates 32 to slide a certain distance on the housing 31, and preventing the two connecting plates 32 from being connected to the threaded rod 1.

[0035] Then, one end of the threaded rod 1 is passed through the housing 31, thereby fitting the housing 31 and the conical tube 39 onto the threaded rod 1. After that, the pressing plate 37 is released and, through the elastic potential energy of the four torsion springs and the transmission between the two rotating shafts 33, the lever 34, the ball 1 35 and the ball 2 36, the two pressing plates 37 are restored to their original state, and one end of the two connecting plates 32 is connected to the threaded rod 1.

[0036] At this time, through the threaded action between the two connecting plates 32 and the threaded rod 1, the housing 31 is unable to move quickly on the threaded rod 1. At the same time, through the self-locking property of the thread between the connecting plates 32 and the threaded rod 1, the housing 31 can be limited.

[0037] In summary, by sequentially installing the two fixing mechanisms 3 and the sanding belt roller 2 onto the threaded rod 1, the sanding belt roller 2 can be fixed. At the same time, by adjusting the distance between the two fixing mechanisms 3, sanding belt rollers 2 of different specifications can be fixed, thus improving convenience and applicability.

[0038] When the two connecting plates 32 are threadedly connected to the threaded rod 1, the housing 31 can be rotated to enable the two connecting plates 32 and the threaded rod 1 to perform threaded transmission, thereby achieving the effect of fine adjustment of the housing 31 and improving flexibility.

[0039] Compared with related technologies, the fixing fixture for assisting in the winding of sandpaper and sanding belt provided by this utility model has the following beneficial effects: through the cooperation of various components, it can not only achieve the effect of fixing sanding belt rollers 2 of different specifications, improving convenience and applicability, but also achieve the effect of fine adjustment of the distance between the two conical tubes 39, improving flexibility. Moreover, the structure is simple and the practicality is higher.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
