[0003] At present, rubber sealing rings are cut by a cutting machine during processing and production, that is, a plate-shaped rubber sheet is placed on a cutting table, and the corresponding sealing ring is cut out on the rubber sheet by moving the cutting knife. However, during the cutting process, the rubber sheet may slide due to the movement of the cutting knife, thereby affecting the finished product effect of the sealing ring. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A rubber sealing ring processing positioning tool comprises an operating table 1, a box body 19 is installed at the bottom of the operating table 1, an opening is arranged at the bottom of the box body 19, and a cover plate 21 is installed on the opening, wherein a first mounting seat 20 is installed at the bottom corner of the box body 19, and a second mounting seat 22 corresponding to the first mounting seat 20 is installed at the corner of the cover plate 21. In actual use, holes for placing bolts are opened on the mounting seat, so that the cover plate 21 can be fixed to the box body 19 by bolts to ensure the airtightness of the bottom of the box body 19, and at the same time, it is convenient to stably fix the positioning tool on the rubber sealing ring cutting machine through the mounting seat for use.

[0023] like Figure 1 and Figure 4 As shown, a carrying plate 2 is installed on the top of the operating table 1, and the carrying plate 2 is located in the middle of the operating table 1. A sliding seat 3 is provided on the side of the carrying plate 2 along the length direction of the side of the carrying plate 2. The sliding seat 3 is arranged on the operating table 1 and penetrates the operating table 1. A slider 4 is slidably installed in the sliding seat 3. A rotating shaft 6 is arranged above the slider 4 in parallel. A fixed seat 5 is rotatably connected to the end of the rotating shaft 6. The fixed seat 5 is fixed on the slider 4, and an "L"-shaped pressing plate 7 bent toward the carrying plate 2 is installed on the rotating shaft 6. The formal projection of the bottom of the pressing plate 7 is as follows: Corresponding to the inner cavity of the sliding seat 3, the slider 4 can pull the bottom of the pressing plate 7 to slide into the sliding seat 3, so that the bottom of the pressing plate 7 is limited by the sliding seat 3, so that its top can be pressed parallel to the top surface of the supporting plate 2, and then the rubber sheet placed on the supporting plate 2 is pressed down and fixed. Due to the "L" shape of the pressing plate 7, after the pressing plate 7 is pressed on the rubber sheet, the side of the rubber sheet can be wrapped to position the rubber sheet, prevent the rubber sheet from being dislocated or sliding on the supporting plate 2, and allow the rubber sheet to be more stably positioned and fixed on the supporting plate 2.

[0024] Furthermore, a torsion spring 8 is sleeved on the end of the rotating shaft 6, one end of the torsion spring 8 is fixed on the pressure plate 7, and the other end of the torsion spring 8 is fixed on the fixed seat 5. After the slider 4 pulls the pressure plate 7 into the sliding seat 3, the torsion spring 8 will undergo elastic deformation, thereby increasing the elastic force of rotation to the pressure plate 7. Therefore, after the slider 4 pushes the pressure plate 7 out of the sliding seat 3, the pressure plate 7 can be pushed away from the supporting plate 2, so as to open the positioning and fixation of the rubber plate by the pressure plate 7, which is convenient for manual picking and placement of the rubber plate.

[0025] like Figure 4 As shown, the slider 4 extends into the box body 19, and the bottom of the slider 4 is vertically fixed on the connecting plate 9, the connecting plate 9 is fixed on the lifting seat 10, and the lifting seat 10 is connected with a screw rod 11 through a nut thread, the top of the screw rod 11 is vertically fixed on the top of the box body 19, the bottom of the screw rod 11 is rotatably mounted on the support plate 13, and the side of the support plate 13 is fixed to the inner wall of the box body 19, and a driving mechanism for driving the screw rod 11 to rotate is connected to the bottom of the screw rod 11. Under the rotation of the screw rod 11, the lifting seat 10 drives the slider 4 to rise and fall, thereby controlling the positioning operation of the pressure plate 7;

[0026] Among them, Figure 2 and Figure 4 As shown, the screw 11 passes through the support plate 13, and the driving mechanism includes a driving shaft 12. The top of the driving shaft 12 is coaxially connected to the screw 11, and a worm wheel 15 is coaxially installed on the driving shaft 12. The side of the worm wheel 15 is meshed with a worm 16, and the ends of the worm 16 are rotatably installed with a fixing frame 17, which is fixed on the support plate 13, and a driving motor 18 is connected to one end of the worm 16. The driving motor 18 is fixed to the fixing frame 17 through a bracket, and the screw 11 is driven to rotate by the worm wheel 15 and the worm 16. At the same time, the driving motor 18 can be placed horizontally in a box 19, thereby reducing the volume of the box 19, so as to improve the adaptability of the positioning tooling during installation.

[0027] It needs to be further explained that if Figure 4 As shown, a plurality of guide shafts 14 are provided in parallel on the side of the screw rod 11. The guide shafts 14 slide through the connecting plate 9. The top of the guide shafts 14 is fixed on the top of the box body 19, and the bottom of the guide shafts 14 is fixed on the supporting plate 13, providing a guiding effect for the lifting and lowering of the slider 4.

[0028] It should be further explained that an "L"-shaped limiting plate 23 is provided at a corner of the supporting plate 2, and the inner wall of the limiting plate 23 is fixed corresponding to the side of the supporting plate 2, so as to limit the placement position of the rubber plate on the supporting plate 2 when placing the rubber plate, so as to position and fix the pressure plate 7.

[0029] Specifically, when in use, first fix the positioning tool on the rubber sealing ring cutting machine, then take the rubber sheet for cutting the sealing ring and place it on the supporting plate 2, and place the corners of the rubber sheet against the limit plate 23, then start the driving motor 18, let the slider 4 pull the pressing plate 7 into the sliding seat 3, at this time, the top of the pressing plate 7 will be parallel to the top surface of the rubber sheet, as the pressing plate 7 continues to fall, it will press on the rubber sheet, thereby positioning and fixing the rubber sheet, and then you can start to control the cutting machine to cut the required sealing ring on the rubber sheet, after the cutting is completed, control the driving motor 18 again to push the pressing plate 7 back to the initial position, at this time the torsion spring 8 will expand the pressing plate 7 outward, and then the worker takes away the waste of the rubber sheet, replaces it with a new rubber sheet, and then the sealing ring processing operation can be carried out again.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
