However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Example:

[0029] See also Figure 1-Figure 2The present embodiment provides a gluing fixture for rubber sealing products, comprising a base 1 and a clamping block 4 and a clamping block 8 both arranged on the base 1; the clamping block 4 is provided with a gluing working surface 6 at one end close to the clamping block 8, the clamping block 4 is provided with a placement hole 3, and one end of the placement hole 3 is connected to the gluing working surface 6; the clamping block 8 is provided with a gluing working surface 7 at one end close to the clamping block 4, the clamping block 8 is provided with a placement hole 9, and one end of the placement hole 9 is connected to the gluing working surface 7;

[0030] The placement hole 1 3 is used to fix a bonding end of the rubber sealing product to be bonded, and the bonding end surface of the bonding end is flush with the bonding working surface 1 6; the placement hole 2 9 is used to fix another bonding end of the rubber sealing product to be bonded, and the bonding end surface of the bonding end is flush with the bonding working surface 2 7;

[0031] At least one of the clamping block 1 4 and the clamping block 2 8 is slidably disposed on the base 1 , and the sliding is used to achieve the bonding working surface 1 6 and the bonding working surface 2 7 to be bonded together and the end of the placement hole 1 3 and the end of the placement hole 2 9 to be butted together.

[0032] Furthermore, in this embodiment, the placement hole 1 3 and the placement hole 2 9 are coaxially arranged, wherein the placement hole 1 3 passes through the clamping block 1 4, and the placement hole 2 9 passes through the clamping block 2 8; the placement hole 1 3 and the placement hole 2 9 are respectively used to place the two bonding ends of the rubber sealing product that need to be bonded, and the placement hole 1 3 and the placement hole 2 9 are coaxially arranged to ensure that the two bonding end faces can be smoothly docked and to ensure that the center lines of the two bonding ends after bonding are as close as possible to each other.

[0033] Preferably, the bonding working surface 1 6 and the bonding working surface 2 7 are both inclined surfaces, and the bonding working surface 1 6 and the bonding working surface 2 7 are parallel to each other. The bonding working surface 1 and the bonding working surface 2 are both set as inclined surfaces. After the bonding end of the rubber sealing product is placed in the placement hole 1 or the placement hole 2, the bonding end can be cut along the inclined surface to obtain a bonding end surface in the form of an inclined surface. The use of the bonding end surface in the form of an inclined surface can increase the area of ​​the bonding end surface, making the bonding between the two bonding ends more stable.

[0034] Preferably, the angles between the bonding working surface 1 6 and the bonding working surface 2 7 and the horizontal plane are 30°-60°, and more preferably 30°-45°. In this embodiment, the angle is set to 30° to achieve the effect of increasing the bonding area.

[0035] Preferably, the base 1 is provided with a slide rail 2, and the clamp block 1 4 and / or the clamp block 2 8 are provided with a slide groove 12, and the sliding setting is realized by the cooperation between the slide rail 2 and the slide groove 12. Specifically, according to the needs, both the clamp block 1 4 and the clamp block 2 8 can be set to a sliding form, or only one of them can be set to a sliding form and the other can be set to a fixed form; the purpose of sliding is to make the gluing working surface 1 6 and the gluing working surface 2 7 fit together and to make the end of the placement hole 1 3 and the end of the placement hole 2 9 butt together, so that the two gluing end faces of the rubber sealing product can fit together for gluing. Figure 1 and Figure 2 As shown, in this embodiment, a slide groove 12 is provided at the bottom of the clamping block 1 4 , and the clamping block 1 slides on the base 1 through the cooperation of the slide rail 2 and the slide groove 12 , while the clamping block 2 8 is fixedly arranged on the base 1 .

[0036] Preferably, the clamp block 1 4 is provided with a fastening bolt hole 10 connected to the placement hole 1 3, the clamp block 2 8 is provided with a fastening bolt hole 2 11 connected to the placement hole 2 9, and fastening bolts 5 are provided in the fastening bolt hole 10 and the fastening bolt hole 2 11. By screwing the fastening bolts 5 into the placement hole 1 3 and the placement hole 2 9 respectively, the adhesive ends of the rubber sealing products in the placement hole 1 and the placement hole 2 can be fixed, which is convenient for subsequent adhesive bonding.

[0037] Furthermore, the fastening bolt hole 10 is located at one end of the clamping block 4 close to the bonding working surface 6, and the fastening bolt hole 2 11 is located at one end of the clamping block 2 8 close to the bonding working surface 2 7, so as to ensure that the bonding end is in a fixed state; since the rubber sealing product itself has the characteristics of flexibility and variability, if the fastening bolt 5 is fixed at a position far away from the bonding end face, its restraining effect on the bonding end face is poor, and the two bonding end faces may not be truly fitted together; therefore, the fastening bolt hole 10 is set at one end of the clamping block 4 close to the bonding working surface 6, and the fastening bolt hole 2 11 is set at one end of the clamping block 2 8 close to the bonding working surface 2 7, so that the fastening bolt 5 can be as close to the bonding end face as possible and play a restraining effect, thereby ensuring that the two subsequent bonding end faces can be truly fitted together.

[0038] In some embodiments, the fastening bolt hole 10 may be arranged on the side of the clamping block 4, and the fastening bolt hole 11 may also be arranged on the side of the clamping block 8. When the fastening bolt hole 10 and the fastening bolt hole 11 are opened on the side, the fastening bolt hole 10 and the fastening bolt hole 11 can be as close to the ends of the placement hole 1 and the placement hole 2 as possible, thereby improving the restraining effect of the fastening bolt 5 on the adhesive end face.

[0039] Furthermore, the gluing fixture of the rubber sealing product also includes a clamping piece, which is used to clamp the clamping block 1 4 and the clamping block 2 8 together to achieve gluing of the two gluing end faces. Preferably, the clamping piece can be an existing product such as an I-shaped clamp or a G-shaped clamp. After the relative sliding between the clamping block 1 4 and the clamping block 2 8 realizes the gluing working surface 1 6 and the gluing working surface 2 7 are attached together, the clamping piece is used to clamp the clamping block 1 4 and the clamping block 2 8 together and let it stand for a certain period of time, so that the gluing between the two gluing end faces can be completed.

[0040] In some embodiments, the cross-sectional shape of the placement hole 1 3 and the placement hole 2 9 is consistent with the cross-sectional shape of the rubber sealing product, so that the gluing end of the rubber sealing product can be easily inserted into the placement hole 1 or the placement hole 2; when the cross-sectional shape of the rubber sealing product is square or irregular, setting the cross-sectional shape of the placement hole 1 3 and the placement hole 2 9 to be consistent with the cross-sectional shape of the rubber sealing product can also play a certain limiting role on the gluing end of the rubber sealing product. Of course, in some embodiments, the placement hole 1 and the placement hole 2 can be set in the form of round holes, and the gluing end can be fixed in the placement hole 1 or the placement hole 2 by the fastening bolt 5. In this case, the versatility of the gluing fixture can be improved. No matter what the cross-sectional shape of the gluing end is, it can be fixed by the fastening bolt 5 after being placed in the placement hole 1 3 or the placement hole 2 9.

[0041] In some embodiments, the clamp block 1 4 and the clamp block 2 8 can both be symmetrical structures, that is: the clamp block 1 4 includes a first clamp block and a second clamp block symmetrically arranged in a vertical plane where the axis of the placement hole 1 3 is located, wherein the first clamp block is provided with a half hole 1, and the second clamp block is provided with a half hole 2, and the first clamp block and the second clamp block are assembled to form clamp block 1 4, and the half hole 1 and the half hole 2 constitute the placement hole 1 3; similarly, the clamp block 2 8 includes a third clamp block and a fourth clamp block symmetrically arranged in a vertical plane where the axis of the placement hole 2 9 is located, wherein the third clamp block is provided with a half hole 3, and the fourth clamp block is provided with a half hole 4, and the third clamp block and the fourth clamp block are assembled to form clamp block 2 8, and the half hole 3 and the half hole 4 constitute the placement hole 2 9. Under this structural form, after the gluing is completed, the clamping block 1 and the clamping block 2 can be disassembled to take out the rubber sealing product after gluing, which can be suitable for the gluing of annular rubber sealing products; at the same time, under this structural form, the gluing end of the rubber sealing product can be clamped by cooperating between half hole 1 and half hole 2, and between half hole 3 and half hole 4 (that is, the fastening bolt 5 can be omitted in this structural form); further, in order to increase the versatility of the gluing clamp, under this structural form, a fastening bolt hole 10 can be provided on the first clamping block or / and the second clamping block, and a fastening bolt hole 2 11 can be provided on the third clamping block or / and the fourth clamping block. When the gluing end cannot be clamped by cooperating between half hole 1 and half hole 2, and between half hole 3 and half hole 4, the fastening bolt 5 is used for clamping.

[0042] The technical solution of this embodiment is specifically:

[0043] Place one bonding end to be bonded in the placement hole 1 3 and the bonding end protrudes from the bonding working surface 1 6, place the other bonding end to be bonded in the placement hole 2 9 and the bonding end protrudes from the bonding working surface 2 7, and complete the fixation of the two bonding ends (fixation is completed by clamping with half holes according to the structure of the bonding fixture, or by clamping with fastening bolts 5);

[0044] Cut the glued end in the placement hole 1 3 along the glued working surface 1 6 to obtain a beveled glued end surface, cut the glued end in the placement hole 2 9 along the glued working surface 2 9 to obtain a beveled glued end surface, and apply glue on the two glued end surfaces;

[0045] Push the clamping block 1 and the clamping block 2 to move relative to each other, so that the bonding working surface 1 6 and the bonding working surface 2 7 are bonded together and the two bonding end surfaces are bonded together, and then stand still for a period of time to complete the bonding between the two bonding end surfaces; after the bonding is completed, take out the bonded rubber sealing product; wherein, in the static state, the clamping block 1 and the clamping block 2 can be clamped by a clamping piece.
