Description

Technical Field

[0001] The invention relates to the field of solid propellant charging technology, and in particular to an automatic core inserting device for a combustion chamber. Background Art

[0002] The traditional thin-layer solid propellant charging process generally does not involve pre-loading of the core rod prior to casting and molding due to limited pouring space. Instead, the core rod is inserted after the combustion chamber is vacuum-sprayed with propellant, and the core rod is removed after the propellant solidifies. The propellant surface is then shaped so that the product finally has a propellant surface shape that meets the process index requirements.

The two positioning members can move synchronously toward or away from the positioning ring, and the two positioning members can move synchronously toward and away from the positioning ring until the positioning groove is coaxial with the positioning ring.

[0008] Preferably, the second conveying mechanism comprises: A second positioning block for supporting the combustion chamber, wherein a second positioning hole with a vertical axis is provided on the top of the second positioning block, wherein the second positioning hole is used for the combustion chamber with a vertical axis to be inserted, and the combustion chamber is restricted from moving radially relative to the second positioning block; The second driving assembly is used to drive the second positioning block to circulate through the second position.

[0009] Preferably, the clamping assembly comprises a clamping jaw and a clamping jaw seat, the clamping jaw is connected to the clamping jaw seat, and the clamping jaw seat can reciprocate between the first position and the second position and can be lifted and lowered vertically.

[0010] Preferably, a pressure sensor is provided between the clamping jaw and the clamping jaw seat, and the pressure sensor is used to detect the pressure between the clamping jaw and the clamping jaw seat in the vertical direction.

[0011] Preferably, it also includes a material receiving trough for connecting to the combustion chamber, the material receiving trough is annular and is used to coaxially surround the combustion chamber and close to the top of the combustion chamber, and the material receiving trough is used to receive the medicine slurry overflowing from the combustion chamber.

[0013] Compared with the prior art, the technical solution of the present application has at least the following beneficial technical effects: 1. The present application sets a clamping assembly, a first conveying mechanism, and a second conveying mechanism. The mandrel is conveyed to the first position by the first conveying mechanism, and the mandrel can be lowered and clamped by the clamping assembly at the first position; the combustion chamber is conveyed to the second position by the second conveying mechanism, and the clamping assembly can rise and move to the second position after clamping the mandrel at the first position. At this time, the mandrel is located directly above the combustion chamber, and then the mandrel is inserted into the combustion chamber by lowering the clamping assembly holding the mandrel, thereby realizing the automation of the core insertion work. By setting a positioning mechanism at the second position, the mandrel is inserted into the combustion chamber in a coaxial state with the combustion chamber through the positioning mechanism, so as to ensure the matching accuracy of the mandrel and the combustion chamber and improve the installation accuracy of the mandrel. Therefore, the present application can realize the automation of the core insertion work, reduce the danger, and improve the installation accuracy of the mandrel and ensure production efficiency.

[0014] 2. The positioning mechanism of the present application guides and positions the mandrel through a positioning ring. When the mandrel is driven down by the clamping assembly at the second position, it passes through the positioning ring. The inner diameter of the positioning ring is set to be consistent with or slightly larger than the outer diameter of the mandrel, so that the mandrel after passing through the positioning ring remains coaxial with the positioning ring, that is, the mandrel is accurately positioned. The combustion chamber at the second position is kept coaxial with the positioning ring by setting a positioning assembly. At this time, the mandrel after passing through the positioning ring is coaxial with the combustion chamber, so that the mandrel is inserted into the combustion chamber in a coaxial state with the combustion chamber to ensure the installation accuracy of the mandrel.

[0015] 3. The positioning assembly of the present application includes two positioning members, and positioning grooves are set on the two positioning members. When the combustion chamber is transported to the second position, the two positioning members move synchronously toward each other until the combustion chamber is embedded in the positioning groove and the combustion chamber contacts the two positioning members. Since the positioning groove is adapted to the outer diameter of the combustion chamber, that is, the diameter of the positioning groove is the same as the outer diameter of the combustion chamber, the combustion chamber is coaxial with the positioning grooves on the two positioning members at this time, and the two positioning grooves are coaxial with the positioning ring when they are coaxial, so that the combustion chamber remains coaxial with the positioning ring. This setting can ensure that the combustion chamber remains coaxial with the positioning ring, and with the positioning function of the positioning ring on the mandrel, the mandrel can be inserted into the combustion chamber while remaining coaxial with the combustion chamber, so as to improve the installation accuracy of the mandrel.

[0016] 4. The second conveying mechanism of the present application is provided with a second positioning block and a second positioning hole for the combustion chamber to be embedded, so as to position the combustion chamber through the second positioning hole, so that the combustion chamber is conveyed with its axis vertical, and the second positioning block is driven by the second driving assembly to circulate through the second position, so as to achieve the purpose of conveying the combustion chamber and passing through the second position. By setting the moving track of the second positioning block to be annular and passing through the second position, it can be ensured that the second positioning block moves with the axis of the second positioning hole vertical, so that the combustion chamber maintains a vertical axis during the conveying process.

[0017] 5. The clamping assembly of the present application is configured to include a clamping jaw and a clamping jaw seat. The mandrel is clamped by the clamping jaw, and the clamping jaw and the mandrel are moved and lifted by the movement and lifting of the clamping jaw seat to complete the automatic core insertion work. A pressure sensor is provided between the clamping jaw and the clamping jaw seat, and the pressure between the clamping jaw and the clamping jaw seat is detected by the pressure sensor to indirectly detect the pressure between the mandrel and the combustion chamber during the process of inserting the mandrel into the combustion chamber, so as to prevent the pressure between the mandrel and the combustion chamber from exceeding the safety value.

[0018] 6. The present application provides a receiving trough, and connects the receiving trough to the combustion chamber. The receiving trough coaxially surrounds the combustion chamber and is close to the top of the combustion chamber. The receiving trough receives the slurry overflowing from the combustion chamber when the core rod is inserted into the combustion chamber, which facilitates recovery and avoids contamination of the equipment and possible safety accidents caused by the overflowing slurry.

[0019] 7. This application sets up a flameproof box. When the combustion chamber reaches the second position, the flameproof box moves close to the second position to allow the combustion chamber to enter the flameproof box through the inlet and outlet. The core insertion groove on the top of the flameproof box allows the clamping assembly holding the core rod to move vertically through, so that the core insertion can proceed normally. If an explosion occurs during the process of inserting the core rod into the combustion chamber, the flameproof box can reduce the damage to the surrounding equipment caused by the explosion, and can reduce the risk of causing the combustion chamber filled with slurry to explode.

[0027] Reference Figure 1-11As shown, the embodiment of the present application provides an automatic core insertion device for a combustion chamber, which includes a frame 1, a first conveying mechanism 2 and a second conveying mechanism 3 arranged on the frame 1, a clamping assembly 4 and a positioning mechanism 5. The frame 1 provides an installation base for each mechanism and component. A core insertion station 11 is provided on the frame 1. The core insertion station 11 is provided with a first position 111 and a second position 112 spaced apart in the horizontal direction. The first conveying mechanism 2 is used to convey a core rod with its axis vertical to the first position 111, and the second conveying mechanism 3 is used to convey a combustion chamber with its axis vertical and make the combustion chamber pass through the second position 112. The clamping assembly 4 is arranged in the core insertion station 11 and can reciprocate between the first position 111 and the second position 112, and the clamping assembly 4 can be lifted and lowered vertically, and is suitable for clamping the core rod with its axis vertical at the first position 111 by the clamping assembly 4, moving the core rod to the top of the combustion chamber located at the second position 112 while maintaining the state, and vertically inserting the core rod into the combustion chamber. The positioning mechanism 5 is disposed at the second position 112, and the positioning mechanism 5 is used to insert the core rod into the combustion chamber in a coaxial state with the combustion chamber.

[0028] Reference Figure 2-4 As shown, the clamping assembly 4 includes a clamping jaw 41 and a clamping jaw seat 42, the clamping jaw 41 is connected to the clamping jaw seat 42, and the clamping jaw seat 42 can reciprocate between the first position 111 and the second position 112 and can be lifted and lowered vertically. Specifically, the clamping jaw 41 adopts a pneumatic centering clamping jaw 41, and the axis of the clamping jaw 41 is vertical, so as to stably and accurately clamp the core rod in the vertical axis state. In this embodiment, the clamping jaw seat 42 is configured to be able to reciprocate horizontally between the first position 111 and the second position 112, and the horizontal movement and vertical lifting of the clamping jaw seat 42 are respectively realized by linear modules, and correspondingly, one linear module is vertically arranged, and the other linear module is horizontally arranged, and the horizontal linear module is installed on the slide of the vertical linear module. This setting can realize the function of reciprocating and lifting of the clamping jaw seat 42 and the clamping jaw 41 between the first position 111 and the second position 112, thereby moving the core rod in the first position 111 to the second position 112 and completing the core insertion action.

[0029] Reference Figure 3-4 As shown, further, a pressure sensor 43 is provided between the clamping jaw 41 and the clamping jaw seat 42, and the pressure sensor 43 is used to detect the pressure between the clamping jaw 41 and the clamping jaw seat 42 in the vertical direction. Specifically, the clamping jaw 41 is connected to the clamping jaw seat 42 through the pressure sensor 43, so as to indirectly detect the pressure between the clamping jaw 41 and the combustion chamber through the pressure sensor 43. The pressure sensor 43 is connected to the control system, and the clamping jaw 41 is controlled to stop descending when the pressure exceeds the set value, so as to avoid the pressure between the mandrel and the combustion chamber exceeding the safe value during the insertion of the mandrel into the combustion chamber and causing safety risks.

[0030] Reference Figure 1-2 and Figure 5As shown, the mandrel and the combustion chamber are transported by the first conveying mechanism 2 and the second conveying mechanism 3 respectively, wherein the first conveying mechanism 2 includes a first driving assembly and a first positioning block 21 for supporting the mandrel, and a first positioning hole with a vertical axis is provided on the top of the first positioning block 21, the first positioning hole is used for the mandrel with a vertical axis to be embedded, and the mandrel is restricted from radial movement when embedded in the first positioning hole, and the first driving assembly is used to drive the first positioning block 21 to circulate through the first position 111. Specifically, since the mandrel needs to be inserted vertically downward into the combustion chamber, one end of the mandrel inserted into the combustion chamber needs to be set downward, so the first positioning hole is set according to the outer diameter of one end of the mandrel inserted into the combustion chamber, i.e., the lower end, so that the lower end of the mandrel can be stably embedded in the first positioning hole and keep the axis vertical for transportation.

[0031] Reference Figure 6-7 As shown, the second driving mechanism includes a second driving assembly and a second positioning block 31 for supporting the combustion chamber. A second positioning hole 311 with a vertical axis is provided on the top of the second positioning block 31. The second positioning hole 311 is used for embedding the combustion chamber with a vertical axis, and the combustion chamber is restricted to move radially relative to the second positioning block 31. The second driving assembly is used to drive the second positioning block 31 to circulate through the second position 112. Specifically, the second positioning hole 311 is configured to include multiple sections with different diameters, and the diameter of each section gradually increases from bottom to top. Each section with different diameters is adapted to a combustion chamber with an outer diameter specification, so that the combustion chamber can be stably embedded in the second positioning hole 311 and keep the axis vertical for transportation, and can meet the transportation requirements of combustion chambers of different specifications. In this embodiment, the second positioning hole 311 is illustrated as including two sections with different diameters.

[0032] Reference Figure 1-2 As shown, the first drive assembly and the second drive assembly both adopt an annular guide rail mechanism, which includes an annular guide rail, a plurality of sliders adapted to and connected to the guide rail, and a drive chain that drives the slider to move on the guide rail. The annular guide rail is horizontally arranged, the rotation axis of the drive chain is vertical, and the slider is fixed to the drive chain. The annular guide rail mechanism is a prior art and will not be described in detail here. Correspondingly, the annular guide rail in the first drive assembly passes through the first position 111, and the annular guide rail in the second drive assembly passes through the second position 112. The first positioning block 21 and the second positioning block 31 are installed on a slider of the corresponding annular guide rail mechanism. This arrangement can realize the functions of conveying the core rod to the first position 111 and conveying the combustion chamber through the second position 112, so as to realize the automatic conveying and loading of the core rod and the combustion chamber.

[0033] Furthermore, in the first driving assembly, each slider of the annular guide mechanism is provided with a first positioning block 21, and in the second driving assembly, each slider of the annular guide mechanism is provided with a second positioning block 31. With this arrangement, after manually loading multiple core rods and combustion chambers onto the corresponding conveying mechanism at one time, the first conveying mechanism 2, the second conveying mechanism 3 and the clamping assembly 4 cooperate to sequentially complete the core insertion work of multiple combustion chambers, without the need for human operation during the process, and after completion, the assembled product is manually removed, thereby improving safety.

[0034] Reference Figure 1-2 As shown, further, in order to improve the efficiency of the core insertion work, a plurality of core insertion stations 11 are provided on the frame 1, and the plurality of core insertion stations 11 are sequentially spaced in the horizontal direction, and a clamping assembly 4 and a positioning mechanism 5 are respectively provided in each core insertion station 11. The annular guide rail of the first drive assembly sequentially passes through a plurality of first positions 111 corresponding to the plurality of core insertion stations 11, and the annular guide rail of the second drive assembly sequentially passes through a plurality of second positions 112 corresponding to the plurality of core insertion stations 11. The distance between two adjacent first positions 111 is set to be twice the distance between two adjacent sliders of the first drive assembly, and the distance between two adjacent second positions 112 is set to be twice the distance between two adjacent sliders of the second drive assembly. Specifically, in this embodiment, in each core insertion station 11, the first position 111 and the second position 112 are spaced along the horizontal first direction, and the plurality of core insertion stations 11 are sequentially spaced along the horizontal direction and perpendicular to the first direction, and the corresponding first drive assembly and the second drive assembly are spaced along the first direction and are located on both sides of the core insertion station 11.

[0035] Through the above arrangement, multiple core rods can be transported one by one to multiple first positions 111, and multiple combustion chambers can be transported one by one to multiple second positions 112. The clamping assembly 4 and the positioning mechanism 5 in each core insertion station 11 operate simultaneously to complete the core insertion work of multiple combustion chambers at the same time, thereby improving production efficiency.

[0036] Reference Figure 6 and Figure 8As shown, further, when the core rod is inserted into the combustion chamber, the slurry in the combustion chamber may overflow. In order to avoid the overflowing slurry from contaminating the equipment and the possible safety risks, a receiving trough 6 for connecting to the combustion chamber is also provided. The receiving trough 6 is annular and is used to coaxially surround the combustion chamber and close to the top of the combustion chamber. The receiving trough 6 is used to receive the slurry overflowing from the combustion chamber. Specifically, the receiving trough 6 includes an annular bottom plate 61, and the outer edge and the inner edge of the bottom plate 61 are bent in the same direction to form a side plate 62 perpendicular to the bottom plate 61, thereby forming an annular trough body with a U-shaped cross section. In order to facilitate the connection of the receiving trough 6 to the combustion chamber, the side plate 62 of the receiving trough 6 located on the inner side is bent away from the edge of the bottom plate 61 toward the inner side of the receiving trough 6 to form a folded edge 63, and the folded edge 63 is used to overlap the end face of the top of the combustion chamber. The receiving trough 6 is connected to the combustion chamber by overlapping the folded edge 63. When the slurry overflows in the combustion chamber, the slurry flows through the folded edge 63 into the trough formed by the two side plates 62 and the bottom plate 61 of the receiving trough 6, so that the overflowed slurry is received by the receiving trough 6.

[0037] Reference Fig. 9 As shown, in order to achieve the purpose of the positioning mechanism 5 to make the core rod be inserted into the combustion chamber in a coaxial state with the combustion chamber, the positioning mechanism 5 includes a positioning ring 51 with a vertical axis and a positioning assembly connected to the positioning ring 51. When the combustion chamber is conveyed to the second position 112, it is located directly below the positioning ring 51. When the core rod moves to the second position 112, it is located directly above the positioning ring 51. The positioning ring 51 allows the core rod to pass through and makes the core rod coaxial with the positioning ring 51 after passing through the positioning ring 51. The positioning assembly is used to keep the combustion chamber at the second position 112 coaxial with the positioning ring 51.

[0038] Reference Fig. 9 As shown, specifically, the positioning ring 51 is in a circular shape and has a diameter that is consistent with or slightly larger than the outer diameter of the largest part of the mandrel diameter, so that the mandrel remains coaxial with the positioning ring 51 after passing through the positioning ring 51. A coaxial guide ring 511 is connected to the top of the positioning ring 51, and the diameter of the guide ring 511 gradually increases from bottom to top, so as to ensure that the mandrel smoothly enters the guide ring 511 when it descends vertically.

[0039] Reference Figure 9-10 As shown, the positioning assembly includes two positioning members 52, and the two positioning members 52 are spaced apart in the horizontal direction. When the combustion chamber passes through the second position 112, it passes between the two positioning members 52. The side where the two positioning members 52 are close to each other is provided with an arc-shaped positioning groove 521 adapted to the outer circle of the combustion chamber. The two positioning members 52 can move synchronously toward or away from the positioning ring 51, and the two positioning members 52 can move synchronously toward and away from the positioning groove 521 and the positioning ring 51.

[0040] Reference Fig. 9As shown, specifically, two vertical mounting plates 53 are arranged on the frame 1 at the second position 112, the surface of the mounting plate 53 is perpendicular to the first direction, and the combustion chamber passes between the two mounting plates 53 when passing the second position 112, two positioning members 52 are respectively connected to the two mounting plates 53, and the moving direction of the positioning members 52 is perpendicular to the surface of the mounting plates 53, and the two positioning members 52 are respectively connected to the corresponding mounting plates 53 through electric cylinders 54, so as to drive the positioning members 52 to move through the electric cylinders 54, and the two electric cylinders 54 are started and stopped synchronously to realize the synchronous movement of the two positioning members 52 towards or away from each other. In this embodiment, the positioning member 52 is a positioning block. A horizontal support plate 55 is arranged at the second position 112, and the support plate 55 is located at the same height as the positioning ring 51, and a through hole is opened on the support plate 55 for the positioning ring 51 to pass through, and the positioning ring 51 passes through the through hole and is fixed to the support plate 55, and the support plate 55 is fixed to the top of the two mounting plates 53, so as to realize the purpose of installing the positioning ring 51 at the second position 112.

[0041] Through the above arrangement, when the combustion chamber is transported to the second position 112, the two positioning members 52 are synchronously moved toward each other until the combustion chamber is embedded in the positioning groove 521 and the combustion chamber contacts the two positioning members 52. Since the positioning groove 521 is adapted to the outer diameter of the combustion chamber, that is, the diameter of the positioning groove 521 is the same as the outer diameter of the combustion chamber, the combustion chamber is coaxial with the positioning grooves 521 on the two positioning members 52 at this time, and the two positioning grooves 521 are coaxial with the positioning ring 51 when they are coaxial, so that the combustion chamber remains coaxial with the positioning ring 51. After the mandrel is driven by the clamping assembly 4 to descend through the positioning ring 51 at the second position 112, it remains coaxial with the positioning ring 51, so that the mandrel is inserted into the combustion chamber in a state coaxial with the combustion chamber to ensure the installation accuracy of the mandrel. Further, see Figure 2 and Fig.11 As shown, in order to avoid the situation where the explosion of slurry in one combustion chamber during the core insertion process causes the explosion of other combustion chambers filled with slurry, a flameproof box 7 is connected to the frame 1 and can be moved relative to the frame 1 in the horizontal direction close to or away from the second position 112. The flameproof box 7 can be moved away from the second position 112 to the outside of the conveying track of the combustion chamber. An inlet and outlet for the combustion chamber located at the second position 112 is provided on the side of the bottom of the flameproof box 7 close to the second position 112, and a side of the flameproof box 7 close to the second position 112 is set as an opening. The flameproof box 7 can be moved to allow the combustion chamber to enter the flameproof box 7 through the opening and the inlet and outlet, and a core insertion opening for the clamping assembly 4 holding the core rod to move vertically through is provided on the top of the flameproof box 7.

[0042] Reference Fig.11As shown, the moving direction of the explosion-proof box 7 is set to be parallel to the first direction, and the movement of the explosion-proof box 7 is also achieved by the linear module. The explosion-proof box 7 is fixedly mounted on the slider of the corresponding linear module. The explosion-proof box 7 can be moved close to the second position 112 so that the combustion chamber and the positioning mechanism 5 can enter the explosion-proof box 7 through the inlet and outlet. At this time, the explosion-proof box 7 and the two mounting plates 53 and the support plate 55 cooperate to form a protective cover arranged outside the combustion chamber. When the slurry explodes, the protective cover formed by the explosion-proof box 7, the support plate 55 and the two mounting plates 53 can minimize the damage to the surrounding equipment caused by the explosion, and reduce the risk of explosion of the surrounding combustion chamber filled with slurry, thereby improving safety.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
