[0043] The present application is described in detail below, examples of embodiments of the present application are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar components or components having the same or similar functions throughout. In addition, if a detailed description of known technology is unnecessary for the features of the present application shown, it is omitted. The embodiments described below by reference to the accompanying drawings are exemplary and are for the purpose of explaining the present application only, and cannot be interpreted as a limitation on the present application.

[0044] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as that generally understood by those skilled in the art to which the present application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have meanings consistent with those in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as such.

[0045] Those skilled in the art can understand that, unless otherwise stated, the singular forms "a", "an" and "the" used herein also include the plural forms. It should be further understood that the phrase "comprising" used in the specification of the present application means that the features, integers, steps, operations, elements and / or components exist, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof. It should be understood that the phrase "and / or" used herein includes all or any one of the associated listed items and all combinations thereof.

[0046] The inventors of the present application have found that, in the assembly process of the carrier, the self-destroying cigarette needs to be bent from a straight strip into a closed ring shape, and the self-destroying cigarette is bonded to the engine head of the carrier by adhesive, and the contact position of the self-destroying cigarette and the engine head needs to be manually maintained unchanged until the self-destroying cigarette and the engine head are stably bonded (e.g. the liquid adhesive is completely cured).

[0047] In the assembly process of the carrier, several groups of pressing blocks can be used to extrude the self-destruction propellant in some areas to realize the fixation between the propellant and the engine head. Since the self-destruction propellant is in a straight strip shape and is relatively hard, it is not easy to be bent into a ring shape. The assembly tooling of this type of pressing block does not have the functions of positioning and fixing the shape, and needs to rely on the circular ring line drawn in advance in the propellant mounting area of the engine head to bend the self-destruction propellant into a circular ring shape in sections. After each section is bent, the self-destruction propellant is glued and pressed by the pressing block until the self-destruction propellant is bent into a ring shape along the circular ring line and is fixed. It can be seen that this way is low in efficiency, and it is difficult for the self-destruction propellant to be completely bent into a ring shape consistent with the circular ring line. The adhesive area between the propellant and the engine head is prone to adhesive failure, and secondary adhesive is often needed. The installation effect of the self-destruction propellant is largely dependent on the experience and operation level of workers, that is, higher requirements are put forward for the experience and operation level of the assembly workers.

[0048] The assembly tooling and the assembly method of the self-destruction propellant of the carrier provided in the application are aimed at solving the above technical problems of the prior art.

[0049] The technical solutions of the application and how the technical solutions of the application solve the above technical problems will be described in detail below with specific examples.

[0050] The embodiment of the application provides an assembly tooling of a self-destruction propellant of a carrier, and a structure diagram of the assembly tooling is as shown in Figure 1 and Figure 2 The assembly tooling comprises at least one first arc fixing assembly 100.

[0051] Each first arc fixing assembly 100 comprises a first arc fixing section 110 and at least one first pressing structure 120. The first arc fixing section 110 has a first propellant clamping groove 110a for limiting at least a part of the self-destruction propellant 300. A part of each first pressing structure 120 is connected with the first arc fixing section 110.

[0052] Another part of each first pressing structure 120 is used to be connected with the engine flange 420 of the carrier, so that at least a part of the self-destruction propellant 300 is tightly attached to the engine head 410 of the carrier.

[0053] In the embodiment, the first arc fixing assembly 100 is used to assist in bending the self-destruction tobacco rod 300 from a straight rod into a ring shape. Specifically, the first rod clamping slot 110a of the first arc fixing segment 110 can limit at least a part of the self-destruction tobacco rod 300 to keep the bending state, and each first pressing structure 120 can apply pressure to the first arc fixing segment 110 by taking the engine flange 420 as the fulcrum, so as to tightly attach the self-destruction tobacco rod 300 limited by the first arc fixing segment 110 to the engine head 410 of the carrier, so that the self-destruction tobacco rod 300 can be quickly positioned and fixed on the engine head 410, greatly improving the bonding firmness between the self-destruction tobacco rod 300 and the engine head 410, without the need for secondary glue filling, improving the assembly efficiency of the self-destruction tobacco rod 300, and greatly reducing the experience and operation level requirements of the assembly workers.

[0054] Moreover, in the bending process of the self-destruction tobacco rod 300, the first rod clamping slot 110a of the first arc fixing segment 110 can limit at least a part of the self-destruction tobacco rod 300 to keep the bending state, which greatly reduces the bending difficulty. And in the process of bonding the self-destruction tobacco rod 300 to the engine head 410 of the carrier, the first arc fixing assembly 100 can keep the contact position of the self-destruction tobacco rod 300 with the engine head 410 unchanged.

[0055] Optionally, the first arc fixing segment 110 can be a circular arc shape.

[0056] Optionally, the first arc fixing segment 110 can be a circular arc shape not more than a semicircular arc.

[0057] In some possible implementations, one first rod clamping slot 110a in at least one first arc fixing segment 110 is used to limit both ends of the self-destruction tobacco rod 300 in a ring shape.

[0058] In the embodiment, the first rod clamping slot 110a of one first arc fixing segment 110 simultaneously limits both ends of the self-destruction tobacco rod 300 in a ring shape, that is, the ring shape of the self-destruction tobacco rod 300 can be basically maintained, which can facilitate reducing the parts of the assembly tooling of the self-destruction tobacco rod 300 of the carrier, reducing the assembly cost, and reducing the assembly and disassembly steps.

[0059] In some possible implementations, each first arc fixing assembly 100 includes two or more first pressing structures 120.

[0060] Optionally, each first pressing structure 120 is uniformly arranged along the circumference of the first arc fixing segment 110. In this way, the first arc fixing segment 110 in each first arc fixing assembly 100 can be provided with more uniform pressure, which is conducive to the self-destruction tobacco rod 300 obtaining more uniform bonding pressure, and further improving the bonding firmness between the self-destruction tobacco rod 300 and the engine head 410.

[0061] In some possible implementation manners, as shown in Figure 3 In a radial cross section of the first arc fixed segment 110, an axis of symmetry of the first cigarette clamping groove 110a is at an angle a with an axial direction of the first arc fixed segment 110, 0 < a < 90°, and an opening of the first cigarette clamping groove 110a is deviated to an inner arc surface of the first arc fixed segment 110.

[0062] In this embodiment, the opening of the first cigarette clamping groove 110a is deviated to the inner arc surface of the first arc fixed segment 110, which can relieve the bending stress of the self-destruction cigarette 300 when it is bent from a straight strip into a ring shape, reduce the risk of breakage of the self-destruction cigarette 300, ensure the integrity of the self-destruction cigarette 300 assembled at the engine head 410, and further ensure the working performance of the self-destruction cigarette 300. On the other hand, it is beneficial to adapt the bonding surface of the self-destruction cigarette 300 limited by the first cigarette clamping groove 110a to the surface shape of the engine head 410, increase the bonding area between the self-destruction cigarette 300 and the engine head 410, and further improve the bonding reliability between the self-destruction cigarette 300 and the engine head 410.

[0063] Optionally, a is a real number.

[0064] Optionally, in the radial cross section of the first arc fixed segment 110, the axis of symmetry of the first cigarette clamping groove 110a is perpendicular to the surface of the engine head 410, so as to improve the degree of adaptation of the bonding surface of the self-destruction cigarette 300 limited by the first cigarette clamping groove 110a to the surface shape of the engine head 410.

[0065] The inventors of the present application consider that when the self-destruction cigarette 300 limited by the first cigarette clamping groove 110a of the first arc fixed segment 110 is bonded with the engine head 410, the end of the first arc fixed segment 110 can be pressed first for rapid positioning. For this purpose, the present application provides the following possible implementation manner for the first arc fixed assembly 100:

[0066] As shown in Figure 1 and Figure 10 At least one first arc fixed assembly 100 of the embodiment of the present application further comprises at least one third pressing structure 130.

[0067] Part of each third pressing structure 130 is connected with the end of the first arc fixed segment 110.

[0068] The other part of each third pressing structure 130 is used to be connected with the engine flange 420 of the carrier, so that at least part of the self-destruction cigarette 300 is tightly attached to the engine head 410 of the carrier.

[0069] In the embodiment, the third pressing structure 130 can also take the engine flange 420 as a fulcrum to apply pressure to the end of the first arc fixed segment 110, so as to tightly attach the self-destruction cartridge 300 limited by the end of the first arc fixed segment 110 to the engine head 410 of the carrier, so that the self-destruction cartridge 300 can be quickly positioned and fixed on the engine head 410, and the assembly efficiency of the self-destruction cartridge 300 is improved.

[0070] In some possible embodiments, the third pressing structure 130 comprises a pressing plate, a third connecting piece 131 and a fourth connecting piece 132.

[0071] One end of the pressing plate is provided with a mounting hole (not shown in the figure), and the other end is provided with a third adjusting hole 130a.

[0072] The third connecting piece 131 connects the pressing plate and the end of the first arc fixed segment 110 through the mounting hole.

[0073] The fourth connecting piece 132 is used to connect the pressing plate and the engine flange 420 through the third adjusting hole 130a.

[0074] In the embodiment, one end of the pressing plate is connected to the end of the first arc fixed segment 110 through the third connecting piece 131, and the other end of the pressing plate is connected to the engine flange 420 through the fourth connecting piece 132, so that pressure can be applied to the end of the first arc fixed segment 110, and the self-destruction cartridge 300 limited by the end of the first arc fixed segment 110 can be tightly attached to the engine head 410 of the carrier, so that the self-destruction cartridge 300 can be quickly positioned and fixed on the engine head 410, and the assembly efficiency of the self-destruction cartridge 300 is improved. The third adjusting hole 130a at the other end of the pressing plate can facilitate the pressing plate to adapt to the installation distance between the first arc fixed segment 110 and the flange hole of the engine flange 420, that is, to ensure that the self-destruction cartridge 300 limited by the first arc fixed segment 110 can be attached to the cartridge mounting area of the engine head 410, and the third pressing structure 130 can also take the engine flange 420 as a fulcrum to apply pressure to the first arc fixed segment 110.

[0075] Optionally, the third connecting piece 131 can be a bolt or a screw, so as to facilitate disassembly and assembly between the pressing plate and the first arc fixed segment 110.

[0076] Optionally, the fourth connecting piece 132 can be a bolt or a screw, so as to facilitate disassembly and assembly between the pressing plate and the engine flange 420.

[0077] Optionally, the third adjusting hole 130a is a third strip-shaped hole.

[0078] Optionally, the third adjusting hole 130a comprises at least two third adjusting sub-holes distributed at a specified interval.

[0079] In some possible implementation manners, the third compression structure 130 comprises a pressing plate and a fourth connecting piece 132.

[0080] One end of the pressing plate is fixedly connected with the end of the first arc fixed segment 110, and the other end of the pressing plate has a third adjusting hole 130a.

[0081] The fourth connecting piece 132 is used for connecting the pressing plate with the engine flange 420 through the third adjusting hole 130a.

[0082] In the embodiment, the pressing plate in the third compression structure 130 can be integrally connected with the first arc fixed segment 110, so as to reduce the probability of missing parts.

[0083] Alternatively, the pressing plate in the third compression structure 130 can be integrally connected with the first arc fixed segment 110 by welding or riveting.

[0084] The inventor of the present application considers that the assembly tooling of the carrier self-destruction cartridge 300 can increase the second arc fixed assembly 200 on the basis of the first arc fixed assembly 100, so as to make the assembly of the self-destruction cartridge 300 more flexible. Therefore, the present application provides one possible implementation manner for the assembly tooling of the carrier self-destruction cartridge 300 as follows:

[0085] As shown in FIG. 1, the assembly tooling of the embodiment of the present application further comprises at least one second arc fixed assembly 200. Figure 1

[0086] Each second arc fixed assembly 200 comprises a second arc fixed segment 210 and a second compression structure 220.

[0087] The second arc fixed segment 210 has a second cartridge clamping slot 210a for limiting at least another part of the self-destruction cartridge 300. The arc length of the second arc fixed segment 210 is smaller than the arc length of the first arc fixed segment 110.

[0088] The second compression structure 220 is connected with the second arc fixed segment 210. The second compression structure 220 is used for making at least another part of the self-destruction cartridge 300 tightly contact with the engine head 410 of the carrier.

[0089] ​In the embodiment, the second strip clamping groove 210a of the second arc fixing segment 210 in the second arc fixing assembly 200 can keep the at least part of the self-destruction tobacco strip 300 not limited by the first arc fixing assembly 100 in the bent state, and each second pressing structure 220 can also take the engine flange 420 as the fulcrum to apply pressure to the second arc fixing segment 210, at least to tightly adhere the self-destruction tobacco strip 300 limited by the second arc fixing segment 210 to the engine head 410 of the carrier, so that the self-destruction tobacco strip 300 can be quickly positioned and fixed on the engine head 410, greatly improving the adhesion between the self-destruction tobacco strip 300 and the engine head 410, without the need for secondary glue filling, improving the assembly efficiency of the self-destruction tobacco strip 300, and greatly reducing the experience and operation level requirements of the assembly workers.

[0090] In addition, the arc length of the second arc fixing segment 210 is smaller than that of the first arc fixing segment 110, which is beneficial on the one hand to fill the limited vacancy of the part of the self-destruction tobacco strip 300 outside the first arc fixing assembly 100, and to provide the part of the self-destruction tobacco strip 300 outside the first arc fixing assembly 100 with the adhesion pressure tightly adhering to the engine head 410 of the carrier; on the other hand, it is beneficial to the cooperation of the second arc fixing assembly 200 and the first arc fixing assembly 100 to realize the personalized assembly layout of the self-destruction tobacco strip 300.

[0091] Optionally, each second arc fixing assembly 200 comprises a second arc fixing segment 210 and two or more second pressing structures 220. In this way, the second pressing structures 220 can cooperate to provide the second arc fixing segment 210 with more uniform pressure, which is beneficial to the self-destruction tobacco strip 300 to obtain more uniform adhesion pressure, thereby improving the adhesion between the self-destruction tobacco strip 300 and the engine head 410.

[0092] In some possible embodiments, as shown in Figure 7 In the radial cross section of the second arc fixing segment 210, the symmetry axis of the second strip clamping groove 210a forms an angle β with the axial direction of the second arc fixing segment 210, 0 < β < 90°, and the opening of the second strip clamping groove 210a is deviated to the inner arc surface of the second arc fixing segment 210.

[0093] In the embodiment, the opening of the second strip clamping groove 210a is inclined to the inner arc surface of the second arc fixing segment 210. On the one hand, the bending stress of the self-destruction strip 300 caused by the bending from a straight strip into a ring shape is relieved, the risk of breakage of the self-destruction strip 300 is reduced, the integrity of the self-destruction strip 300 assembled to the engine head 410 is ensured, and the working performance of the self-destruction strip 300 is ensured. On the other hand, the bonding surface of the self-destruction strip 300 limited by the second strip clamping groove 210a is adapted to the surface shape of the engine head 410, the bonding area between the self-destruction strip 300 and the engine head 410 is increased, and the bonding reliability between the self-destruction strip 300 and the engine head 410 is improved.

[0094] Optionally, β is a real number.

[0095] Optionally, in the radial section of the second arc fixing segment 210, the symmetry axis of the second strip clamping groove 210a is perpendicular to the surface of the engine head 410, so as to improve the adaptability of the bonding surface of the self-destruction strip 300 limited by the second strip clamping groove 210a to the surface shape of the engine head 410.

[0096] The inventor of the present application considers that in each first arc fixing assembly 100, the first pressing structure 120 needs to apply effective pressure to the first arc fixing segment 110, or in each second arc fixing assembly 200, the second pressing structure 220 needs to apply effective pressure to the second arc fixing segment 210. Therefore, the present application provides the following possible implementation for the first pressing structure 120 or the second pressing structure 220:

[0097] The first pressing structure 120 and / or the second pressing structure 220 of the embodiment of the present application comprises a connecting bracket, an adjusting rod, a pressing piece and a connecting piece.

[0098] One end of the connecting bracket has a threaded hole, and the other end has an adjusting hole.

[0099] The connecting piece is used to connect the connecting bracket and the engine flange 420 through the adjusting hole.

[0100] The adjusting rod comprises an adjusting part and a connecting part. The connecting part is located at one end of the adjusting part and is rotatably connected with the pressing piece. At least part of the adjusting part has a thread, which is threadedly matched with the threaded hole.

[0101] The pressing piece abuts against the first arc fixing segment 110, and / or the pressing piece abuts against the second arc fixing segment 210.

[0102] The first pressing structure 120 and the second pressing structure 220 will be described respectively as follows.

[0103] In some possible implementation manners, as Figure 4The first pressing structure 120 includes a first connecting bracket 121, a first adjusting rod 122, a first pressing piece 123, and a first connecting piece 124.

[0104] As shown in FIG. 1, the first adjusting rod 122 includes a first adjusting portion 122a and a first connecting portion 122b. Figure 6 As shown in FIG. 1, one end of the first connecting bracket 121 has a first threaded hole 121a, and the other end has a first adjusting hole 121b.

[0105] The first connecting piece 124 is used to connect the first connecting bracket 121 with the engine flange 420 through the first adjusting hole 121b.

[0106] The first adjusting rod 122 includes a first adjusting portion 122a and a first connecting portion 122b. The first connecting portion 122b is located at one end of the first adjusting portion 122a and is rotatably connected with the first pressing piece 123. At least part of the first adjusting portion 122a has a first thread which is threadedly matched with the first threaded hole 121a.

[0107] The first pressing piece 123 abuts against the first arc fixed segment 110.

[0108] In the embodiment, the first thread on the first adjusting portion 122a of the first adjusting rod 122 is threadedly matched with the first threaded hole 121a at one end of the first connecting bracket 121, so that the first adjusting rod 122 and one end of the first connecting bracket 121 form a screw rod connecting pair. In the process of circumferential rotation of the first adjusting rod 122 with its axial direction as the rotation axis, the first adjusting rod 122 can be advanced or retreated in the axial direction, and the distance between the first pressing piece 123 rotatably connected with the first adjusting portion 122a of the first adjusting rod 122 and one end of the first connecting bracket 121 can be adjusted, i.e., the first pressing piece 123 can be abutted against the first arc fixed segment 110, and the pressing force of the first pressing piece 123 against the first arc fixed segment 110 can be adjusted, so as to improve the bonding firmness between the self-destruction tobacco rod 300 and the engine head 410.

[0109] The first adjusting hole 121b at the other end of the first connecting bracket 121 is beneficial for the first pressing piece 123 at one end of the first connecting bracket 121 to abut against the first arc fixed segment 110 after the self-destruction tobacco rod 300 limited by the first arc fixed segment 110 is bonded to the tobacco rod mounting area of the engine head 410, and the other end of the first connecting bracket 121 can also be connected with the flange hole of the engine flange 420 and use the engine flange 420 as the fulcrum, so that the first pressing piece 123 can apply a pressing force to the first arc fixed segment 110.

[0110] In some possible embodiments, the second pressing structure 220 includes a second connecting bracket, a second adjusting rod, a second pressing piece, and a second connecting piece. The first pressing structure 120 shown in FIG. 1 can be referred to. Figure 4 ​

[0111] The second connecting support has a second threaded hole at one end and a second adjusting hole at the other end. For reference Figure 6 the first connecting support 121 shown.

[0112] The second connecting support is connected with the engine flange 420 through the second adjusting hole.

[0113] The second adjusting rod comprises a second adjusting part and a second connecting part. The second connecting part is located at one end of the second adjusting part and is rotatably connected with the second pressing piece. At least part of the second adjusting part has a second thread, which is threadedly matched with the second threaded hole.

[0114] The second pressing piece abuts against the second arc fixed segment 210.

[0115] In the embodiment, the second thread on the second adjusting part of the second adjusting rod is threadedly matched with the second threaded hole at one end of the second connecting support, so that the second adjusting rod and the one end of the second connecting support form a screw rod connecting pair. In the process of circumferential rotation of the second adjusting rod with its axial direction as the rotation axis, the second adjusting rod can advance and retreat in the axial direction, and further adjust the distance between the second pressing piece rotatably connected with the second adjusting part of the second adjusting rod and the one end of the second connecting support, that is, the second pressing piece can abut against the second arc fixed segment 210, and the adjustment of the pressing force of the second pressing piece against the second arc fixed segment 210 can be realized to improve the bonding firmness between the self-destruction tobacco rod 300 and the engine head 410.

[0116] The second adjusting hole at the other end of the second connecting support is beneficial to the abutment of the second pressing piece at one end of the second connecting support against the second arc fixed segment 210 after the self-destruction tobacco rod 300 limited by the second arc fixed segment 210 is bonded to the tobacco rod mounting area of the engine head 410, and the other end of the second connecting support can also be connected with the flange hole of the engine flange 420, and the second pressing piece can exert a pressing force against the second arc fixed segment 210 by taking the engine flange 420 as the fulcrum.

[0117] The inventor of the present application considers that in the first pressing structure 120 or the second pressing structure 220, the connecting part of the adjusting rod needs to be rotatably connected with the pressing piece. Therefore, the present application provides the following possible implementation manner for the first pressing structure 120 or the second pressing structure 220:

[0118] In the first pressing structure 120 or the second pressing structure 220 of the embodiment of the present application, the connecting part is a ball head part, and the radial dimension of the ball head part is greater than the radial dimension of the adjusting part.

[0119] The pressing piece comprises a base and a limiting plate. The base has a semi-spherical cavity accommodating a part of the spherical head, and the limiting plate has a hinge through hole sleeving another part of the spherical head.

[0120] The maximum aperture of the hinge through hole is smaller than the radial dimension of the spherical head, and the minimum aperture of the hinge through hole is larger than the radial dimension of the adjusting part.

[0121] The first pressing structure 120 and the second pressing structure 220 will be described respectively as follows.

[0122] In some possible embodiments, as shown in Figure 4 and Figure 5 The first connecting part 122b is a first spherical head, the radial dimension of the first spherical head is larger than the radial dimension of the first adjusting part 122a, the first pressing piece 123 comprises a first base 1231 and a first limiting plate 1232. The first base 1231 has a first semi-spherical cavity accommodating a part of the first spherical head, and the first limiting plate 1232 has a first hinge through hole sleeving another part of the first spherical head. The maximum aperture of the first hinge through hole is smaller than the radial dimension of the first spherical head, and the minimum aperture of the first hinge through hole is larger than the radial dimension of the first adjusting part 122a.

[0123] In the embodiment, the first semi-spherical cavity of the first base 1231 cooperates with the first limiting plate 1232 to realize the ball hinge connection structure of the first pressing piece 123 and the first spherical head of the first adjusting rod 122, and realize the rotatable connection between the first connecting part 122b of the first adjusting rod 122 and the first pressing piece 123, so that the abutting surface of the first pressing piece 123 can better adapt to the surface angle of the first arc fixed segment 110, that is, the abutting area of the first pressing piece 123 and the first arc fixed segment 110 can be improved, the stability of the first pressing piece 123 and the first arc fixed segment 110 when abutting can be improved, stress concentration can be reduced, wear between the first pressing piece 123 and the first arc fixed segment 110 can be reduced, and the service life of the parts can be prolonged.

[0124] The radial dimension of the first spherical head is larger than the radial dimension of the first adjusting part 122a, the maximum aperture of the first hinge through hole is smaller than the radial dimension of the first spherical head, and the minimum aperture of the first hinge through hole is larger than the radial dimension of the first adjusting part 122a, so that a certain degree of freedom can be provided for the rotation of the first spherical head in the first semi-spherical cavity, and the first spherical head can be prevented from escaping from the first semi-spherical cavity to cause connection failure.

[0125] In some possible implementations, the second connecting portion is a second spherical head, the radial dimension of which is larger than the radial dimension of the second adjusting portion. The second pressing member includes a second base and a second limiting plate. The second base has a second hemispherical cavity accommodating a portion of the second spherical head, and the second limiting plate has a second hinged through-hole fitted onto the other portion of the second spherical head. The maximum diameter of the second hinged through-hole is smaller than the radial dimension of the second spherical head, and the minimum diameter of the second hinged through-hole is larger than the radial dimension of the second adjusting portion. See also... Figure 4 and Figure 5 The first clamping structure 120 shown.

[0126] In this embodiment, the second hemispherical cavity of the second base cooperates with the second limiting plate to form a ball joint connection structure between the second pressing member and the second ball head of the second adjusting rod. This enables a rotatable connection between the second connecting part of the second adjusting rod and the second pressing member, allowing the contact surface of the second pressing member to better adapt to the surface angle of the second arc fixing segment 210. This increases the contact area between the second pressing member and the second arc fixing segment 210, improves the stability when the second pressing member and the second arc fixing segment 210 are in contact, reduces stress concentration, reduces wear between the second pressing member and the second arc fixing segment 210, and extends the service life of the components.

[0127] The radial dimension of the second ball head is greater than the radial dimension of the second adjusting part, the maximum diameter of the second hinge through hole is less than the radial dimension of the second ball head, and the minimum diameter of the second hinge through hole is greater than the radial dimension of the second adjusting part. This provides a certain degree of freedom for the rotation of the second ball head in the second hemispherical cavity, and also prevents the second ball head from escaping from the second hemispherical cavity, which would lead to connection failure.

[0128] In some possible implementations, the adjustment holes in the first clamping structure 120 and / or the second clamping structure 220 are strip-shaped holes.

[0129] Optionally, the first adjustment hole 121b is a first strip hole.

[0130] Optionally, the second adjustment hole is a second strip hole.

[0131] In some possible implementations, the adjustment holes in the first clamping structure 120 and / or the second clamping structure 220 include at least two adjustment sub-holes distributed at a specified interval.

[0132] Optionally, the first adjustment hole 121b includes at least two first adjustment sub-holes distributed at a specified interval.

[0133] Optionally, the second adjustment hole includes at least two second adjustment sub-holes distributed at a specified interval.

[0134] The inventors of the present application consider that in the first pressing structure 120, the pressing piece needs to be in effective abutment with the first arc fixed segment 110; in the second pressing structure 220, the pressing piece is in effective abutment with the second arc fixed segment 210. For this purpose, the present application provides the following possible implementation for the first pressing structure 120 or the second pressing structure 220:

[0135] In the first pressing structure 120 or the second pressing structure 220 of the embodiments of the present application, the first arc fixed segment 110 has a limiting groove and / or the second arc fixed segment 210 has a limiting groove, the groove bottom of the limiting groove is in abutment with the pressing piece, and the groove wall of the limiting groove at least limits the rotation of the pressing piece along the axial direction of the adjusting rod.

[0136] The first pressing structure 120 and the second pressing structure 220 will be described respectively as follows.

[0137] In some possible implementation manners, as shown in Figure 3 The first arc fixed segment 110 has a first limiting groove 110b, the groove bottom of the first limiting groove 110b is in abutment with the first pressing piece 123, and the groove wall of the first limiting groove 110b at least limits the rotation of the first pressing piece 123 along the axial direction of the first adjusting rod 122.

[0138] In the present embodiment, the first limiting groove 110b on the first arc fixed segment 110 can be in certain fitting cooperation with the first pressing piece 123, which is conducive to the quick positioning of the first pressing piece 123 on the first arc fixed segment 110 during the assembly process, thereby improving the assembly efficiency of the first arc fixed assembly 100. The groove wall of the first limiting groove 110b at least limits the rotation of the first pressing piece 123 along the axial direction of the first adjusting rod 122, which can constrain the degree of freedom of the rotation of the first pressing piece 123 along with the first adjusting rod 122 when the first adjusting rod 122 and one end of the first connecting bracket 121 form a screw rod connecting pair to adjust the pressing force of the first pressing piece 123 on the first arc fixed segment 110, thereby reducing the probability of the first pressing piece 123 deviating from the abutment with the first arc fixed segment 110 and improving the effectiveness of the abutment of the first pressing piece 123 with the first arc fixed segment 110.

[0139] In some possible implementation manners, as shown in Figure 7 The second arc fixed segment 210 has a second limiting groove 210b, the groove bottom of the second limiting groove 210b is in abutment with the second pressing piece, and the groove wall of the second limiting groove 210b at least limits the rotation of the second pressing piece along the axial direction of the second adjusting rod.

[0140] In the embodiment, the second limiting groove 210b on the second arc fixed segment 210 can be embeddedly matched with the second pressing piece, which is beneficial to the quick positioning of the second pressing piece on the second arc fixed segment 210 in the assembling process, and improves the assembling efficiency of the second arc fixed assembly 200. The groove wall of the second limiting groove 210b at least limits the axial rotation of the second pressing piece along the second adjusting rod, which can constrain the freedom degree of the rotation of the second pressing piece along the second adjusting rod when the second pressing piece is adjusted by the screw rod connecting pair formed by the second adjusting rod and one end of the second connecting support, and further reduces the probability of the disengagement of the second pressing piece from the abutment with the second arc fixed segment 210, and improves the effectiveness of the abutment of the second pressing piece with the second arc fixed segment 210.

[0141] Based on the same inventive concept, the embodiment of the present application provides an assembly method of the self-destruction drug strip of the carrier, based on the assembly tool of the self-destruction drug strip of the carrier provided in any one of the preceding embodiments, a flowchart of the assembly method is shown in Figure 8 The method comprises steps S101-S103.

[0142] S101: limiting a part of the self-destruction drug strip in the first drug strip clamping groove of the first arc fixed segment of at least one first arc fixed assembly.

[0143] S102: bonding the self-destruction drug strip to the engine head of the carrier by adhesive.

[0144] S103: connecting one part of at least one first pressing structure in the first arc fixed assembly with the first arc fixed segment, and connecting the other part with the engine flange of the carrier, so that at least a part of the self-destruction drug strip is tightly attached to the engine head of the carrier.

[0145] In the embodiment, the self-destruction drug strip 300 can be first bent, and at least one first arc fixed assembly 100 is used to assist in bending the self-destruction drug strip 300 from a straight strip into a ring shape. Specifically, at least a part of the self-destruction drug strip 300 is limited in the bent state by the first drug strip clamping groove 110a of the first arc fixed segment 110, which greatly reduces the bending difficulty.

[0146] Then, the self-destruction drug strip 300 is bonded to the engine head 410 of the carrier, and the first arc fixed assembly 100 is used to keep the contact position of the self-destruction drug strip 300 with the engine head 410 unchanged. Specifically, the self-destruction drug strip 300 is kept in the bent state by continuously using the first drug strip clamping groove 110a of the first arc fixed segment 110.

[0147] The first compression structure 120 is used as a fulcrum to apply pressure to the first arc fixed segment 110 by means of the engine flange 420, so that the self-destruction drug strip 300 is limited by the first arc fixed segment 110 and tightly attached to the engine head 410 of the carrier, so that the self-destruction drug strip 300 can be quickly positioned and fixed on the engine head 410, the adhesion between the self-destruction drug strip 300 and the engine head 410 is greatly improved, secondary glue filling is not needed, the assembly efficiency of the self-destruction drug strip 300 is improved, and the experience and operation level requirements of the assembly workers are greatly reduced.

[0148] The embodiment of the present application provides a deployment method of a carrier self-destruction drug strip assembly method, a flowchart of the method is as shown in Figure 9 The method comprises the following steps S201-S207.

[0149] S201: A part of the self-destruction drug strip is limited in the first drug strip clamping groove of the first arc fixed segment of the at least one first arc fixed assembly.

[0150] In step S201, the first drug strip clamping groove 110a of the first arc fixed segment 110 is used to limit at least a part of the self-destruction drug strip 300 in a bent state, so that the bending difficulty is greatly reduced.

[0151] In some possible implementation manners, the step S201 of limiting a part of the self-destruction drug strip in the first drug strip clamping groove of the first arc fixed segment of the at least one first arc fixed assembly can comprise the following steps.

[0152] The self-destruction drug strip is bent into a ring shape.

[0153] Both ends of the self-destruction drug strip in the ring shape are limited in the first drug strip clamping groove of the first arc fixed segment of the first arc fixed assembly.

[0154] In some possible implementation manners, the step S201 of limiting a part of the self-destruction drug strip in the first drug strip clamping groove of the first arc fixed segment of the at least one first arc fixed assembly can comprise the following steps.

[0155] One end of the self-destruction drug strip is limited in the first drug strip clamping groove of the first arc fixed segment of the first arc fixed assembly.

[0156] After the other end of the self-destruction drug strip is bent into a ring shape, the other end is also limited in the first drug strip clamping groove.

[0157] S202: A part of the at least one third compression structure is connected with the end of the first arc fixed segment. Then, step S204 is performed.

[0158] A state diagram after step S202 is as shown in Figure 10 .

[0159] S203: The self-destruction drug strip is adhered to the engine head of the carrier by the adhesive. Then step S204 is performed.

[0160] The state after step S203 is shown in Figure 11 .

[0161] Alternatively, step S202 can be performed before step S203, that is, first connect a part of the at least one third pressing structure 130 with the end of the first arc fixing segment 110, then apply adhesive to the self-destruction drug strip 300, and adhere the self-destruction drug strip 300 to the engine head 410 of the carrier by the adhesive.

[0162] Alternatively, step S202 can be performed after step S203, that is, first apply adhesive to the self-destruction drug strip 300, and adhere the self-destruction drug strip 300 to the engine head 410 of the carrier by the adhesive, and then connect a part of the at least one third pressing structure 130 with the end of the first arc fixing segment 110.

[0163] Alternatively, step S202 can be performed simultaneously with step S203.

[0164] S204: Connect another part of the third pressing structure with the engine flange of the carrier, so that at least a part of the self-destruction drug strip is tightly attached to the engine head of the carrier.

[0165] After step S204, at least the part of the self-destruction drug strip 300 limited to the end of the first arc fixing segment 110 is tightly attached to the engine head 410 of the carrier, so that the self-destruction drug strip 300 can be quickly positioned and fixed on the engine head 410, improving the assembly efficiency of the self-destruction drug strip 300.

[0166] S205: Connect a part of the at least one first pressing structure in the first arc fixing assembly with the first arc fixing segment, and connect another part with the engine flange of the carrier, so that at least a part of the self-destruction drug strip is tightly attached to the engine head of the carrier.

[0167] After step S205, as shown in Figure 12 , each first pressing structure 120 can apply pressure to the first arc fixing segment 110 by taking the engine flange 420 as the fulcrum, at least the self-destruction drug strip 300 limited by the first arc fixing segment 110 is tightly attached to the engine head 410 of the carrier, so that the self-destruction drug strip 300 can be quickly positioned and fixed on the engine head 410, greatly improving the adhesion between the self-destruction drug strip 300 and the engine head 410, without the need for secondary adhesive, improving the assembly efficiency of the self-destruction drug strip 300, and greatly reducing the experience and operation level requirements of the assembly workers.

[0168] Optionally, in step S205, each first pressing structure 120 is arranged uniformly along the circumference of the first arc fixing segment 110. In this way, the first arc fixing segment 110 in each first arc fixing assembly 100 can be provided with more uniform pressure, which is conducive to obtaining more uniform bonding pressure of the self-destructive tobacco rod 300, and further improves the bonding firmness between the self-destructive tobacco rod 300 and the engine head 410.

[0169] Optionally, in the process of circumferential rotation of the first adjusting rod 122 in the first pressing structure 120 with the axial direction of the first adjusting rod 122 as the rotation axis in step S205, the first adjusting rod 122 is advanced and retreated in the axial direction, and the distance between the first adjusting part 122a of the first adjusting rod 122 and one end of the first connecting bracket 121 is adjusted, that is, the first pressing piece 123 can be abutted to the first arc fixing segment 110, and the adjustment of the pressing force of the first pressing piece 123 to the first arc fixing segment 110 is realized, so as to improve the bonding firmness between the self-destructive tobacco rod 300 and the engine head 410.

[0170] Optionally, in step S205, the first adjusting hole 121b at the other end of the first connecting bracket 121 can be used to adjust the position of the first connecting bracket 121, so that the first pressing piece 123 at one end of the first connecting bracket 121 can abut to the first arc fixing segment 110, and the other end of the first connecting bracket 121 can also be connected to the flange hole of the engine flange 420, and the first pressing piece 123 can exert a pressing force to the first arc fixing segment 110 by taking the engine flange 420 as the fulcrum.

[0171] S206: Another part of the self-destructive tobacco rod is limited in the second tobacco rod clamping groove of the second arc fixing segment of at least one second arc fixing assembly.

[0172] After step S206, the second tobacco rod clamping groove 210a of the second arc fixing segment 210 in the second arc fixing assembly 200 can keep at least part of the self-destructive tobacco rod 300 that is not limited by the first arc fixing assembly 100 in a bent state,

[0173] In addition, the arc length of the second arc fixing segment 210 is smaller than that of the first arc fixing segment 110, which is conducive to filling the limitation vacancy of the part of the self-destructive tobacco rod 300 outside the first arc fixing assembly 100, and is also conducive to the cooperation of the second arc fixing assembly 200 and the first arc fixing assembly 100 to realize the personalized assembly layout of the self-destructive tobacco rod 300.

[0174] Optionally, in step S206, each of the second arc fixing components 200 is evenly arranged along the circumference of the self-destructing strip 300 that is not limited by the first arc fixing component 100. This provides more uniform pressure to the self-destructing strip 300 that is not limited by the first arc fixing component 100, which helps the self-destructing strip 300 obtain more uniform bonding pressure, thereby improving the reliability of the bond between the self-destructing strip 300 and the engine head 410.

[0175] S207: Connect a portion of the second clamping structure in the second arc fixing assembly to the second arc fixing section, and another portion to the engine flange of the carrier, such that at least another portion of the self-destructing strip is in close contact with the engine head of the carrier.

[0176] After step S207, as Figure 1 As shown, each second clamping structure 220 can also apply pressure to the second arc fixing section 210 using the engine flange 420 as the force point, at least ensuring that the self-destructing strip 300 limited by the second arc fixing section 210 is tightly adhered to the engine head 410 of the carrier. This allows the self-destructing strip 300 to be quickly positioned and fixed on the engine head 410, greatly improving the reliability of the bond between the self-destructing strip 300 and the engine head 410. No secondary adhesive application is required, improving the assembly efficiency of the self-destructing strip 300 and significantly reducing the experience and skill requirements for assembly workers. Since the arc length of the second arc fixing section 210 is less than the arc length of the first arc fixing section 110, the second arc fixing assembly 200 can also provide adhesive pressure to the engine head 410 of the carrier for the portion of the self-destructing strip 300 located outside the first arc fixing assembly 100.

[0177] Optionally, in step S207, during the circumferential rotation of the second adjusting rod in the second pressing structure 220 about its own axis, the second adjusting rod moves forward and backward in the axial direction, thereby adjusting the distance between the second pressing member rotatably connected to the second adjusting part of the second adjusting rod and one end of the second connecting bracket. This allows the second pressing member to abut against the second arc fixing section 210, and also allows for adjustment of the pressure applied by the second pressing member to the second arc fixing section 210, thereby improving the reliability of the adhesion between the self-destructing strip 300 and the engine end cap 410.

[0178] Optionally, in step S207, the position of the second connecting bracket can be adjusted using the second adjustment hole at the other end of the second connecting bracket, so that the second pressure member located at one end of the second connecting bracket can abut against the second arc fixing section 210, and the other end of the second connecting bracket can also be connected to the flange hole of the engine flange 420. With the engine flange 420 as the force point, the second pressure member can apply pressure to the second arc fixing section 210.

[0179] It can be understood that after step S207, the adhesive bonding between the to-be-destroyed medicine strip 300 and the engine head 410 is stable (for example, the liquid adhesive is completely cured), and then the first arc fixing assembly 100 and the second arc fixing assembly 200 are successively fixed, so that the assembly of the to-be-destroyed medicine strip 300 is completed.

[0180] By applying the embodiment of the present application, the following beneficial effects can be achieved:

[0181] 1. At least one first arc fixing assembly 100 is used to assist in bending the to-be-destroyed medicine strip 300 from a straight strip into a ring shape. Specifically, during the bending process of the to-be-destroyed medicine strip 300, the first medicine strip clamping groove 110a of the first arc fixing segment 110 can limit at least a part of the to-be-destroyed medicine strip 300 in a bent state, which greatly reduces the bending difficulty.

[0182] 2. During the process of bonding the to-be-destroyed medicine strip 300 to the engine head 410 of the carrier, the first arc fixing assembly 100 can keep the contact position of the to-be-destroyed medicine strip 300 with the engine head 410 unchanged. Specifically, the first medicine strip clamping groove 110a of the first arc fixing segment 110 can keep the to-be-destroyed medicine strip 300 in a bent state, and each first pressing structure 120 can apply pressure to the first arc fixing segment 110 by taking the engine flange 420 as a fulcrum, so as to tightly bond at least the to-be-destroyed medicine strip 300 limited by the first arc fixing segment 110 to the engine head 410 of the carrier, so that the to-be-destroyed medicine strip 300 can be quickly positioned and fixed on the engine head 410, which greatly improves the bonding firmness between the to-be-destroyed medicine strip 300 and the engine head 410, eliminates the need for secondary glue filling, improves the assembly efficiency of the to-be-destroyed medicine strip 300, and greatly reduces the experience and operation level requirements for the assembly workers.

[0183] 3. The first medicine strip clamping groove 110a of one first arc fixing segment 110 simultaneously limits the two ends of the to-be-destroyed medicine strip 300 in a ring shape, so as to basically keep the to-be-destroyed medicine strip 300 in a ring shape, which can facilitate reducing the parts of the assembly tooling of the carrier to-be-destroyed medicine strip 300, reducing the assembly cost and reducing the assembly and disassembly steps.

[0184] 4. Each first pressing structure 120 is uniformly arranged along the circumference of the first arc fixing segment 110. In this way, more uniform pressure can be provided for the first arc fixing segment 110 in each first arc fixing assembly 100, which is beneficial to the to-be-destroyed medicine strip 300 to obtain more uniform bonding pressure, thereby improving the bonding firmness between the to-be-destroyed medicine strip 300 and the engine head 410.

[0185] 5. The opening of the first strip groove 110a is biased towards the inner arc surface of the first arc fixing section 110. On the one hand, this can alleviate the bending stress on the self-destructing strip 300 when it is bent from a straight strip into a ring shape, reduce the risk of the self-destructing strip 300 breaking, ensure the integrity of the self-destructing strip 300 assembled to the engine head 410, and thus ensure the working performance of the self-destructing strip 300. On the other hand, it is beneficial for the bonding surface of the self-destructing strip 300 limited by the first strip groove 110a to adapt to the surface shape of the engine head 410, increase the bonding area between the self-destructing strip 300 and the engine head 410, and thus improve the reliability of the bonding between the self-destructing strip 300 and the engine head 410.

[0186] 6. The third clamping structure 130 in the first arc fixing assembly 100 can also use the engine flange 420 as the force point to apply pressure to the end of the first arc fixing section 110, so that at least part of the self-destructing strip 300 located at the end of the first arc fixing section 110 is tightly attached to the engine head 410 of the carrier, so that the self-destructing strip 300 can be quickly positioned and fixed on the engine head 410, thereby improving the assembly efficiency of the self-destructing strip 300.

[0187] 7. The second strip slot 210a of the second arc fixing section 210 in the second arc fixing assembly 200 can keep at least a portion of the self-destructing strip 300 that is not limited by the first arc fixing assembly 100 in a bent state. Each second clamping structure 220 can also apply pressure to the second arc fixing section 210 with the engine flange 420 as the force point, so that at least the self-destructing strip 300 limited by the second arc fixing section 210 is tightly attached to the engine head 410 of the carrier. This allows the self-destructing strip 300 to be quickly positioned and fixed on the engine head 410, which greatly improves the reliability of the bond between the self-destructing strip 300 and the engine head 410. No secondary glue application is required, which improves the assembly efficiency of the self-destructing strip 300 and greatly reduces the requirements for the experience and operation level of the assembly workers.

[0188] 8. The arc length of the second arc fixing segment 210 is less than that of the first arc fixing segment 110. On the one hand, this helps to fill the limiting gap of the self-destructing explosive strip 300 located outside the first arc fixing component 100, and also provides the bonding pressure of the engine head 410 of the carrier for the self-destructing explosive strip 300 located outside the first arc fixing component 100. On the other hand, it helps the second arc fixing component 200 to cooperate with the first arc fixing component 100 to achieve a personalized assembly layout for the self-destructing explosive strip 300.

[0189] 9、The first screw thread on the first adjusting part 122a of the first adjusting rod 122 is threadedly connected with the first threaded hole 121a on one end of the first connecting bracket 121, so that the first adjusting rod 122 and the one end of the first connecting bracket 121 form a screw connection pair, and the first adjusting rod 122 can move forward and backward in the axial direction during the circumferential rotation of the first adjusting rod 122 with the axial direction as the rotation axis, and the distance between the first pressing piece 123 rotatably connected with the first adjusting part 122a of the first adjusting rod 122 and the one end of the first connecting bracket 121 can be adjusted, that is, the first pressing piece 123 can be abutted to the first arc fixed segment 110, and the pressure applied by the first pressing piece 123 to the first arc fixed segment 110 can be adjusted to improve the bonding strength between the self-destruction tobacco rod 300 and the engine head 410.

[0190] 10、The first adjusting hole 121b on the other end of the first connecting bracket 121 can be used to abut the first pressing piece 123 on the one end of the first connecting bracket 121 to the first arc fixed segment 110 after the self-destruction tobacco rod 300 limited by the first arc fixed segment 110 is bonded to the tobacco rod mounting area of the engine head 410, and the other end of the first connecting bracket 121 can also be connected with the flange hole of the engine flange 420, and the first pressing piece 123 can apply pressure to the first arc fixed segment 110 by taking the engine flange 420 as the fulcrum.

[0191] 11、The first half-spherical cavity of the first base 1231 cooperates with the first limiting plate 1232 to form a spherical hinge connection structure between the first pressing piece 123 and the first ball head part of the first adjusting rod 122, and the rotatable connection between the first connecting part 122b of the first adjusting rod 122 and the first pressing piece 123 is realized, so that the abutting surface of the first pressing piece 123 can better adapt to the surface angle of the first arc fixed segment 110, that is, the abutting area between the first pressing piece 123 and the first arc fixed segment 110 can be increased, the stability of the first pressing piece 123 and the first arc fixed segment 110 when abutting can be improved, stress concentration can be reduced, wear between the first pressing piece 123 and the first arc fixed segment 110 can be reduced, and the service life of the parts can be prolonged.

[0192] 12、The first limiting groove 110b on the first arc fixed segment 110 can be embedded with the first pressing piece 123, which is beneficial for the first pressing piece 123 to be quickly positioned on the first arc fixed segment 110 during the assembly process, thereby improving the assembly efficiency of the first arc fixed assembly 100. The groove wall of the first limiting groove 110b at least limits the axial rotation of the first pressing piece 123 along the first adjusting rod 122, so that when the first pressing piece 123 is adjusted by the first adjusting rod 122 and the one end of the first connecting bracket 121 to form a screw connection pair to adjust the pressing force of the first pressing piece 123 to the first arc fixed segment 110, the freedom of the first pressing piece 123 rotating with the first adjusting rod 122 is constrained, thereby reducing the probability of the first pressing piece 123 disengaging from the abutment with the first arc fixed segment 110, and improving the effectiveness of the abutment of the first pressing piece 123 with the first arc fixed segment 110.
