[0033] A radial positioning and axial pressurizing bonding device for an adhesive, characterized in that it comprises a base plate 1, two crescent positioning blocks 2, a clamping block 3, a clamping circular plate 4 and a locking screw 5; wherein a base plate screw hole 12 is provided at the center of the base plate 1, a clamping block screw hole 31 is provided in the middle of the clamping block 3, and a clamping circular plate screw hole 41 is provided in the center of the clamping circular plate 4; the crescent positioning block 2 is a portion smaller than a semicircle obtained by vertically cutting a circular plate, and a square groove 21 is provided in the middle of the cut surface of the crescent positioning block 2;

[0034] During operation, the clamping block 3 is placed in the middle of the substrate 1, and the two ends of the clamping block 3 are clamped in the square grooves 21 of the two crescent positioning blocks 2. The annular component Ⅰ10 and the annular component Ⅱ20 that need to be tightly bonded together are arranged on the outer sleeve of the crescent positioning block 2; the clamping circular plate 4 is pressed on the clamping block 3, the two crescent positioning blocks 2 and the upper surface of the annular component Ⅱ20; the locking screw 5 is screwed into the clamping circular plate screw hole 41 on the clamping circular plate 4, the clamping block screw hole 31 on the clamping block 3 and the substrate screw hole 12 on the substrate 1, and the locking screw 5 fastens the clamping circular plate 4, the clamping block 3 and the substrate 1 together.

[0035] The specific implementation of the present invention, such as the shape and features of each component and the positional relationship between the various parts, will be further explained below through practical description with reference to the accompanying drawings.

[0036] As attached Figure 7It is a schematic diagram of the crescent positioning block 2 of the present invention. During the bonding process, the annular component I10 and the annular component II20 need to be radially positioned and axially pressurized. When positioning and pressurizing the annular component I10 and the annular component II20, the operating steps are as follows: apply adhesive to the bonding surfaces of the annular component I10 and the annular component II20. Then, the bonding surface of the annular component I10 coated with adhesive faces upward and is placed on the substrate so that the center position of the adhesive corresponds to the center of the threaded hole of the substrate. Then, the arcs of the two crescent positioning blocks 2 are facing outward so that the notch of the square groove is aligned with the middle of the annular component I10 on the substrate. Then, the bonding surface of the annular component II20 coated with adhesive is aligned with the bonding surface of the annular component I10 and pressed. Put the pressing block 3 into the square groove of the crescent positioning block. Then, place the gasket 6 on the pressing block 3 so that the middle hole of the gasket 6 is aligned with the middle hole on the pressing block 3. Then put the clamping circular plate 4 on the gasket, aligning the middle hole of the clamping circular plate 4 with the middle hole of the gasket 6. Then use a torque wrench to screw the locking bolts into the threaded holes of the clamping circular plate 4, gasket 6, clamping block 3 and base plate to radially position and axially clamp the annular component I10 and the annular component II20.

[0037] The present invention is directed to the existing bonding methods. The bonded products have uneven thickness of the adhesive layer 30, poor consistency of the overall bonding strength, and are difficult to control the relative positions of the parts after bonding. It can be seen that the adhesive parts bonded by the existing bonding methods and bonding devices do not meet the use requirements. A radial positioning axial pressure bonding method and bonding device are introduced. The adhesive parts bonded by the bonding method and bonding device introduced in the present invention have uniform thickness of the adhesive layer, good consistency of the bonding strength, and high relative position accuracy of the bonding parts.

[0038] The above describes the device and method used in the present invention in conjunction with the accompanying drawings. The specific implementation of the present invention is not limited to the bonding of the above-mentioned components. As long as the bonding device and method of the present invention are adopted to carry out various improved designs, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.

[0039] A method for radial positioning and axial pressure bonding of adhesive parts, characterized in that the bonding device comprises: a substrate 10, a crescent positioning block, a clamping block 3, a clamping circular plate 4, a gasket 6, and a locking screw 5. The substrate 1, the crescent positioning block 2, and the clamping plate 3 limit the radial movement of the annular component I10 and the annular component II20, the substrate 1 and the clamping plate 3 limit the axial movement of the annular component I10 and the annular component II20, and the gasket 6 limits the thickness of the adhesive layer. The locking screw 5 plays a locking role in the overall bonding process. The steps include:

[0040] ① Apply adhesive to the bonding surfaces of the annular component Ⅰ10 and the annular component Ⅱ20.

[0041] ② Place the annular component I10 coated with adhesive with the adhesive surface facing upward on the substrate, so that the center position of the adhesive corresponds to the center of the threaded hole of the substrate.

[0042] ③ Place the two crescent positioning blocks 2 with their arcs facing outwards, and align the notch of the square groove 21 with the middle of the annular component Ⅰ10 on the substrate.

[0043] ④Align the adhesive surface of the annular component II 20 and the adhesive surface of the annular component I 10 and press lightly.

[0044] ⑤ Place the pressing block 3 into the square groove 21 of the crescent positioning block 2.

[0045] ⑥ Place the gasket 6 on the pressing block 3 so that the middle hole of the gasket 6 is aligned with the middle hole on the pressing block 3.

[0046] ⑦ Place the pressing circular plate 4 on the gasket 6 so that the middle hole of the pressing circular plate 4 is aligned with the middle hole of the gasket 6.

[0047] ⑧ Use a torque wrench to screw the locking screw 5 into the clamping circular plate 4, the gasket, the clamping block 3 and the threaded hole 12 of the base plate.

[0048] ⑨ After curing is completed, remove the locking screw 5, the pressing circular plate 4, the gasket 6, and the pressing block 3.

[0049] The base plate 1, the pressing block 3, the gasket 6 and the pressing circular plate 4 are used to axially lock the adhesive parts, see the attached Figure 3 .

[0050] The shape of the crescent positioning block is crescent-shaped, with a square groove at the right angle. The middle surface of the square groove has a certain taper. See attached Figure 4 .

[0051] The shape of the clamping block 3 is a hexahedron with a hole in the middle, in which the two faces parallel to the axis of the middle hole have the same taper angle, see the attached Figure 4 .

[0052] The two tapered surfaces of the clamping block 3 and the tapered surface of the square groove 221 of the crescent positioning block cooperate with each other to form a wedge-shaped compression. The crescent positioning block 2 tightens the annular component I10 and the annular component II20 under the action of the wedge-shaped compression force. Figure 3 The protrusion of the ring 43 on the pressing circular plate 4 is in contact with the non-bonding surface of the annular component II 20, see attached Figure 3 .

[0053] The base plate 1, the crescent positioning block 2, the pressing block 3, the gasket 6 and the pressing circular plate 4 play a positioning role during the bonding process.

[0054] The gasket 6 is in the shape of a cuboid with a hole in the middle.

[0056] A method and device for radial positioning and axial pressure bonding of adhesive parts, the device used in the bonding method includes: a substrate, a crescent positioning block, a clamping block 3, a clamping circular plate 4, a gasket, and a locking screw. The substrate, the crescent positioning block, and the clamping plate 1 limit the radial movement of the annular component I10 and the annular component II20, the substrate and the clamping plate 2 limit the axial movement of the annular component I10 and the annular component II20, and the gasket limits the thickness of the adhesive layer. The locking screw plays a locking role in the overall bonding process during the bonding process. Therefore, this method solves the problems of difficult control of the thickness of the adhesive layer, uneven adhesive layer, low consistency of the overall bonding strength, and difficult control of the relative position of each part after bonding, ensuring that the thickness of the adhesive layer of the adhesive part is stable and controllable, and the consistency of the bonding strength is high. In addition, the accuracy of the relative position of each part after bonding is also ensured. The bonding method and bonding device used in the present invention are suitable for bonding metal and metal rings, metal and non-metal rings, and non-metal and non-metal rings.

[0057] There is a threaded hole in the middle of the base plate, see attached Figure 3 The threaded holes on the substrate, the clamping block 3, the gasket, and the clamping circular plate 4 jointly axially lock the adhesive component, see attached Figure 1 The shape of the crescent positioning block is crescent-shaped, with a square groove at the right angle side, and the middle surface of the square groove has a certain taper, see attached Figure 4 The shape of the clamping block 3 is a hexahedron with a hole in the middle, wherein the two faces parallel to the axis of the middle hole have the same taper angle, see attached Figure 5 The two tapered surfaces of the clamping block 3 and the tapered surface of the square groove of the crescent positioning block cooperate to form a wedge-shaped compression. The crescent positioning block supports the annular component I10 and the annular component II20 under the action of the wedge-shaped compression force. See attached Figure 1 The shape of the pressing circular plate 4 is a whole circular cake with a hole in the middle, and one surface of the circular cake is close to the outer circle and has an annular protrusion, see the attached Figure 6 The annular protrusion on the pressing circular plate 4 is in contact with the non-bonding surface of the annular component II 20, see attached Figure 1 The substrate, crescent positioning block, pressing block 3, gasket, and pressing circular plate 4 play a positioning role during the bonding process.
