Description

Technical Field

[0001] This utility model relates to the technical field of gas generator testing, and in particular to a quick change tooling for a gas generator venting device. Background Technology

[0002] During the production of gas generators, a series of tests are required, including a gas release performance test. This performance test necessitates the use of a venting device, which contains fixtures used to stabilize and fix the gas generator.

[0003] In particular, due to the variety of gas generators, in order to meet the requirements of testing the venting effect of gas generators with different diameters, it is necessary to match tooling of different diameters to fix the gas generator. When changing tooling, the operation is difficult and the tooling changeover time is long, resulting in low testing efficiency.

[0004] To reduce the operation time for changing fixed tooling, the tooling needs to be improved. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing tools that can only be used with gas generators of a single size, have long operation time when changing tools, and have poor performance. It provides a quick tooling changeover tool for gas generator venting equipment that is convenient to change tools, has short operation time, and has good performance.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick-change tooling for a gas generator venting device, comprising:

[0007] The base has a stepped assembly cavity inside, and an exhaust hole is provided at the bottom of the assembly cavity;

[0008] A support ring is detachably installed at the upper end of the assembly cavity, and the support gas generator tube is placed inside the support ring.

[0009] A stabilizing ring is detachably installed in the middle of the assembly cavity. The gas generator outlet end is embedded in the stabilizing ring. A stabilizing block that can be pushed outward is provided on the outer wall of the stabilizing ring. The stabilizing block is in contact with the assembly cavity.

[0010] This fixture includes a base, a support ring, and a stabilizing ring. The base is mounted on the venting device of the gas generator. The base has an internal assembly cavity with a stepped, perforated structure and an exhaust port at the bottom. Both the support ring and the stabilizing ring are detachably mounted within the assembly cavity. When the support ring and stabilizing ring are not installed, a large-diameter gas generator can be directly mounted inside the assembly cavity, with the gas generator's tube contour contacting the inner cavity to secure it. This ensures stable mounting of the large-diameter gas generator during venting tests. When the support ring and stabilizing ring are installed within the assembly cavity of the base, reducing the cavity's inner diameter, the support ring, mounted at the upper end of the assembly cavity, supports the tube of the smaller-diameter gas generator when mounted on the base. A stabilizing ring is installed in the middle of the assembly cavity. A stabilizing block is set on the outer wall of the stabilizing ring, which can be pushed outward. After the stabilizing block is pushed outward, it contacts the middle side wall of the assembly cavity, making the stabilizing ring and the assembly cavity stable. A small-diameter gas generator is installed inside the support ring, with the end face of the gas generator contacting the end face of the stabilizing ring for stable installation. The gas generator's outlet end is embedded in the stabilizing ring, facilitating operation during subsequent venting tests. This structure can stably fix a small-diameter gas generator. Furthermore, by installing the support ring and stabilizing ring inside the assembly cavity, the time required to replace the base is avoided, enabling rapid tooling changeover, improving operational convenience, and increasing testing efficiency.

[0011] Preferably, the assembly cavity is provided with an upper cavity, a middle cavity, and a lower cavity in sequence, with the inner diameters of the upper, middle, and lower cavities decreasing sequentially. The exhaust port is connected to the bottom surface of the lower cavity. The upper and middle cavities are used to stably support the gas generator tube, and the gas generator outlet is embedded in the lower cavity. Specifically, the assembly cavity includes the upper, middle, and lower cavities arranged in sequence, with the inner diameters decreasing sequentially. During the venting test of a large-diameter gas generator, the gas generator is directly inserted into the assembly cavity. The upper and middle cavities support the gas generator tube, while the gas generator outlet is embedded in the lower cavity. Simultaneously, the exhaust port is connected to the bottom surface of the lower cavity, allowing gas to be discharged from the exhaust port during venting. This structure can meet the venting test requirements of large-diameter gas generators and ensure the stability of the gas generator during the test.

[0012] Preferably, the upper chamber sidewall is provided with a vent hole, and the lower chamber sidewall is provided with a buffer hole. The vent hole in the upper chamber sidewall allows for venting when the gas generator or stabilizing ring is inserted, facilitating operation. The buffer hole in the lower chamber sidewall acts as a buffer, preventing excessive impact force during venting of the gas generator, thus avoiding relative vibration between the gas generator and the tooling, ensuring the normal operation of the venting equipment and guaranteeing the test results.

[0013] Preferably, the support ring is installed in the upper cavity, and a transition platform is provided between the upper cavity and the middle cavity. The transition platform has a transition chamfer, and the lower end face of the support ring contacts the transition platform. The inner diameter of the support ring is the same as the inner diameter of the middle cavity. The support ring is a ring-shaped structure installed in the upper cavity, which forms a stepped structure with the middle cavity. A transition platform is provided at the connection between the upper and middle cavities. When the support ring is installed in the upper cavity, the end face of the support ring contacts the transition platform, ensuring stable installation. Simultaneously, the transition chamfer on the transition platform reduces the contact area between the transition platform and the support ring, facilitating tool insertion from the chamfer during support ring disassembly. This makes operation simple and convenient, improving the efficiency of tooling changeover.

[0014] Preferably, the stabilizing ring is installed within the central cavity, and a clearance groove is provided on the outer wall of the stabilizing ring. A clearance platform is provided at the connection between the central cavity and the lower cavity, and the clearance groove engages with the clearance platform. Specifically, the stabilizing ring is installed within the central cavity, and a clearance groove is provided at the lower end of the outer wall of the stabilizing ring. Simultaneously, the central and lower cavities have a stepped structure, and a clearance platform is provided at the connection. The clearance grooves are matched and installed to ensure the installation of the stabilizing ring. Furthermore, the lower end face of the stabilizing ring is positioned above the buffer hole. This structure ensures stable installation of the stabilizing ring, alters the inner diameter of the central cavity, accommodates the fixing of small-diameter gas generators, ensures the normal operation of the venting equipment, and guarantees good experimental results.

[0015] Preferably, the stabilizing ring has a mounting cavity on its side wall, a pull rod is installed in the mounting cavity, a locking block is provided at the lower end of the pull rod, and a mounting groove is provided on the outer side wall of the stabilizing ring. The stabilizing block is installed in the mounting groove, and the stabilizing block and the locking block are matched and engaged. Specifically, the mounting cavity is provided inside the side wall of the stabilizing ring, the pull rod is installed inside the mounting cavity, the upper end of the pull rod is provided with a ring-shaped buckle, and the lower end of the pull rod is provided with a locking block. Simultaneously, the mounting groove is provided on the outer side of the stabilizing ring, and the stabilizing block is installed inside the mounting groove. When the pull rod moves within the mounting cavity, it allows the locking block to engage with the stabilizing block, controlling the outward and inward movement of the stabilizing block. When the stabilizing block moves outward, it contacts the inner wall of the cavity, improving the installation stability of the stabilizing ring. When the stabilizing block retracts, it facilitates the disassembly of the stabilizing ring. This structure allows for convenient tooling changeover operations and shortens the operation time.

[0016] Preferably, the mounting groove and the mounting cavity are provided with a connecting hole, the stabilizing block is provided with a push rod, the push rod is placed in the connecting hole, the side wall of the locking block is provided with a wedge-shaped surface, the wedge-shaped surface is provided with a locking hole, and the push rod can be embedded in the locking hole. The design incorporates a connecting hole between the mounting slot and the mounting cavity, allowing the push rod within the stabilizing block to be inserted. Simultaneously, the end of the push rod extends beyond the connecting hole into the lower end of the mounting cavity. A wedge-shaped surface with a locking hole is provided on the side wall of the locking block. This locking hole matches the push rod. When the pull rod is pushed down, the wedge-shaped surface pushes the push rod outward, propelling the stabilizing block outward to contact the inner wall of the central cavity, thus stabilizing the ring. To disassemble the stabilizing ring, the pull rod is pulled upward, removing the push rod from the locking hole and causing the stabilizing block to retract, facilitating ring disassembly. Furthermore, when the pull rod is pulled upward, the locking block contacts the stepped surface of the mounting cavity, allowing the stabilizing ring to move upward and facilitating disassembly. This design allows for convenient tooling changeover operations with short operation times.

[0017] The beneficial effects of this utility model are: by installing a support ring and a stabilizing ring to change the inner diameter of the assembly cavity, it can meet the requirements of gas generators of different diameters for gas release tests. This tooling is simple and convenient to operate in the changeover operation, and at the same time has good stability, ensuring good test results. Attached Figure Description

[0027] Example 1, such as Figure 1-5 As shown, a quick-change tooling for a gas generator venting device includes: a base 1, wherein a stepped assembly cavity is provided inside the base 1, and an exhaust hole 2 is provided at the bottom of the assembly cavity; a support ring 3, wherein the support ring 3 is detachably installed at the upper end of the assembly cavity, and the gas generator tube is placed inside the support ring 3; and a stabilizing ring 4, wherein the stabilizing ring 4 is detachably installed in the middle of the assembly cavity, and the gas generator outlet end is embedded in the stabilizing ring 4, and a stabilizing block 5 that can be pushed outward is provided on the outer wall of the stabilizing ring 4, and the stabilizing block 5 is in contact with the assembly cavity.

[0028] The assembly cavity is provided with an upper cavity 6, a middle cavity 7 and a lower cavity 8 in sequence. The inner diameters of the upper cavity 6, the middle cavity 7 and the lower cavity 8 decrease in sequence. The exhaust hole 2 is connected to the bottom surface of the lower cavity 8. The upper cavity 6 and the middle cavity 7 are used to stably support the gas generator tube. The gas generator outlet end is embedded in the lower cavity 8.

[0029] The upper cavity 6 has a vent hole 60 on its side wall, and the lower cavity 8 has a buffer hole 80 on its side wall.

[0030] The support ring 3 is installed in the upper cavity 6. A transition platform 9 is provided between the upper cavity 6 and the middle cavity 7. The transition platform 9 is provided with a transition chamfer 90. The lower end face of the support ring 3 is in contact with the transition platform 9.

[0031] The stabilizing ring 4 is installed in the middle cavity 7. The outer wall of the stabilizing ring 4 is provided with a relief groove 40. A relief platform 10 is provided at the connection between the middle cavity 7 and the lower cavity 8. The relief groove 40 is engaged with the relief platform 10.

[0032] The stabilizing ring 4 has a mounting cavity 41 on its side wall. A pull rod 42 is installed in the mounting cavity 41. A locking block 43 is provided at the lower end of the pull rod 42.

The side wall of the locking block 43 is provided with a wedge-shaped surface 46, and the wedge-shaped surface 46 is provided with a locking hole 47.

[0034] The working principle of this utility model is as follows: Figure 1-5As shown, this fixture includes a base 1, a support ring 3, and a stabilizing ring 4. The base 1 is mounted on the venting device of the gas generator. The base 1 has an internal assembly cavity with a stepped, perforated structure and an exhaust port 2 at its bottom. Both the support ring 3 and the stabilizing ring 4 are detachably mounted within the assembly cavity of the base 1. When the support ring 3 and stabilizing ring 4 are not installed, a large-diameter gas generator can be directly mounted inside the assembly cavity, with the outline of the gas generator's tube contacting the inner cavity to secure it. This ensures stable mounting of the large-diameter gas generator during venting tests. When the support ring 3 and stabilizing ring 4 are installed within the assembly cavity of the base 1, reducing the inner diameter of the cavity, and the support ring 3 is mounted at the upper end of the assembly cavity, with the gas generator mounted on the base 1, the support ring 3 supports the tube of the smaller-diameter gas generator. A stabilizing ring 4 is installed in the middle of the assembly cavity. A stabilizing block 5 is set on the outer wall of the stabilizing ring 4. The stabilizing block 5 can be pushed outward. After the stabilizing block 5 is pushed outward, it contacts the middle side wall of the assembly cavity, making the stabilizing ring 4 and the assembly cavity stable. A small-diameter gas generator is installed inside the support ring 3 within the stabilizing ring 4, with the end face of the gas generator contacting the end face of the stabilizing ring 4 for stable installation. The outlet end of the gas generator is embedded in the stabilizing ring 4, facilitating operation during subsequent venting tests. This structure can stably fix a small-diameter gas generator. Furthermore, by installing the support ring 3 and the stabilizing ring 4 within the assembly cavity, the time required to replace the base 1 is avoided, enabling rapid tooling changeover, improving operational convenience, and increasing testing efficiency.

[0035] The assembly cavity includes an upper cavity 6, a middle cavity 7, and a lower cavity 8 arranged sequentially. The inner diameters of the upper cavity 6, middle cavity 7, and lower cavity 8 decrease sequentially. When conducting a venting test on a large-diameter gas generator, the gas generator is directly inserted into the assembly cavity. The upper cavity 6 and middle cavity 7 serve to support the gas generator tube. The gas generator's outlet is embedded in the lower cavity 8. At the same time, the exhaust port 2 is connected to the bottom surface of the lower cavity 8, so that when the gas generator vents, the gas can be discharged from the exhaust port 2. This structure can meet the venting test requirements of large-diameter gas generators and ensure the stability of the gas generator during the test.

[0036] The upper chamber 6 has a vent hole 60 on its side wall, which allows for venting when the gas generator or stabilizing ring 4 is inserted, facilitating operation. The lower chamber 8 has a buffer hole 80 on its side wall, which acts as a buffer to prevent excessive impact force when the gas generator is venting, thus avoiding relative vibration between the gas generator and the tooling, ensuring the normal operation of the venting equipment and ensuring the test results.

[0037] The support ring 3 is a ring-shaped structure installed in the upper cavity 6. The upper cavity 6 and the middle cavity 7 form a stepped structure. A transition platform 9 is provided at the connection between the upper cavity 6 and the middle cavity 7. When the support ring 3 is installed in the upper cavity 6, the end face of the support ring 3 contacts the transition platform 9, ensuring the stability of the support ring 3 installation. At the same time, a transition chamfer 90 is provided on the transition platform 9. This transition chamfer 90 can reduce the contact area between the transition platform 9 and the support ring 3. When disassembling the support ring 3, it is convenient to insert tools from the transition chamfer 90, which facilitates the disassembly of the support ring 3, making the operation simple and convenient, and improving the tooling changeover efficiency.

[0038] The stabilizing ring 4 is installed inside the middle cavity 7. A relief groove 40 is provided at the lower end of the outer wall of the stabilizing ring 4. The middle cavity 7 and the lower cavity 8 have a stepped structure, and a relief platform 10 is provided at the connection. The relief groove 40 is matched and installed to ensure the installation of the stabilizing ring 4. At the same time, the lower end face of the stabilizing ring 4 is placed on the upper end of the buffer hole 80. This structure can stabilize the installation of the stabilizing ring 4, change the inner diameter of the middle cavity 7, meet the requirements for fixing small-diameter gas generators, ensure the normal operation of the venting equipment, and ensure good test results.

[0039] The stabilizing ring 4 has an installation cavity 41 inside its side wall. A pull rod 42 is installed inside the installation cavity 41. The upper end of the pull rod 42 is provided with an annular buckle, and the lower end of the pull rod 42 is provided with a locking block 43. Meanwhile, an installation groove 44 is provided on the outside of the stabilizing ring 4. The stabilizing block 5 is installed inside the installation groove 44. When the pull rod 42 moves in the installation cavity 41, the locking block 43 can cooperate with the stabilizing block 5 to control the outward movement and inward retraction of the stabilizing block 5. When the stabilizing block 5 moves outward, it contacts the inner wall of the middle cavity 7, improving the installation stability of the stabilizing ring 4. When the stabilizing block 5 retracts, it facilitates the disassembly of the stabilizing ring 4. This structure makes tooling changeover operations convenient and reduces operation time.

[0040] A connecting hole 45 is provided between the mounting groove 44 and the mounting cavity 41. This connecting hole 45 allows the push rod 50 in the stabilizing block 5 to be inserted. Simultaneously, the end of the push rod 50 extends beyond the connecting hole 45 into the lower end of the mounting cavity 41. A wedge-shaped surface 46 is provided on the side wall of the locking block 43, and a locking hole 47 is provided on this wedge-shaped surface 46. The locking hole 47 matches the push rod 50. When the pull rod 42 is pushed down, due to the structure of the wedge-shaped surface 46, the push rod 50 can be pushed outwards. The stabilizing block 5 is pushed outward to contact the inner wall of the central cavity 7, completing the stable installation of the stabilizing ring 4. When it is necessary to remove the stabilizing ring 4, the pull rod 42 is pulled upward to move the push rod 50 out of the locking hole 47, so that the stabilizing block 5 is retracted, which facilitates the removal of the stabilizing ring 4. At the same time, when the pull rod 42 is pulled upward, the locking block 43 can contact the stepped surface of the mounting cavity 41, which facilitates the upward movement of the stabilizing ring 4 and makes it easy to remove the stabilizing ring 4. Thus, the design of this structure makes tooling change operation convenient and the operation time short.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
