Description

Technical Field

[0001] This invention relates to a device for measuring the rollover of small and medium-sized solid rocket motors. Background Technology

[0002] During the assembly of small and medium-sized solid rocket motors, pyrotechnic components need to be installed into the housing, and a compensation pad of appropriate thickness should be added between the pyrotechnic component and the housing to ensure that the depth of the pyrotechnic component after installation meets the process requirements, and this depth value needs to be measured.

[0003] During assembly, to ensure safety, a compensation pad is typically placed on the upper surface of the pyrotechnic component before the housing is fitted onto it from top to bottom. Therefore, based on these process requirements, in existing small and medium-sized solid rocket motor assembly technologies, the depth of the pyrotechnic component inserted into the housing is usually measured directly after assembly, requiring manual intervention, especially for pressing and multi-point measurements of products of different sizes. Furthermore, to ensure accurate measurements, pressure must be applied to the pyrotechnic component during measurement, with varying pressures applied to different product specifications. Simultaneously, stable positioning of the product must be ensured, further increasing the difficulty of manual operation. Moreover, due to varying skill levels among operators, the efficiency and accuracy of existing methods often fail to meet production requirements. Additionally, during assembly and measurement, the pyrotechnic component and housing are prone to combustion or explosion due to compression, increasing the risk of accidents during manual operation. Summary of the Invention

[0017] 1. This invention enables automatic clamping, flipping, and measurement of small and medium-sized stationary engine products, improving measurement efficiency. After the pyrotechnic components, supplementary pads, and housing are placed, they are initially clamped by the clamping mechanism and the measuring block in the measuring mechanism to eliminate gaps between them. Then, the flipping frame is rotated 180°, at which point the pyrotechnic components further clamp the supplementary pads by their own weight.

[0019] 3. This invention can achieve multi-point measurement in the circumferential and horizontal directions. The pressure seat in the pressing mechanism clamps the closed end of the housing and drives the entire product under test to rotate, thereby achieving multi-point measurement in the circumferential direction. The limiting and moving component in the measuring mechanism can adjust the horizontal degree of freedom of the measuring pressure block, thereby achieving multi-point measurement in the horizontal direction, thus further ensuring measurement accuracy.

[0020] 4. When placing pyrotechnic items, supplementary pads, and housings, the clamping mechanism in the avoidance clamping unit is driven to move laterally to the avoidance position by the lateral drive component, so that there will be no interference affecting the placement. When measuring and flipping, the product under test is clamped by the anti-tipping units on both sides of the middle of the flipping frame to prevent it from tipping over, thereby ensuring the smooth progress of the measurement.

[0021] 5. This invention can meet the measurement requirements of products of different specifications.

Detailed Implementation

[0031] The invention will now be described in further detail with reference to the accompanying drawings.

[0032] like Figures 1-7 As shown, the present invention includes a main frame 5, a flipping unit 4, an avoidance and clamping unit 1, and a measuring unit 2, wherein... Figure 7 As shown, the flipping unit 4 includes a flipping frame 401, and the flipping frame 401 is rotatably mounted on the main frame 5, as shown. Figure 1 As shown, the avoidance and clamping unit 1 is located at one end of the tilting frame 401, and the measuring unit 2 is located at the other end of the tilting frame 401, as follows. Figures 2-3 As shown, the avoidance and clamping unit 1 includes a clamping and lifting assembly, a lateral drive assembly, and a clamping mechanism 107. The lateral drive assembly and the clamping mechanism 107 are driven to move up and down via the clamping and lifting assembly, and the clamping mechanism 107 is driven to move laterally via the lateral drive assembly. Figures 4-5As shown, the measuring unit 2 includes a measuring lifting assembly and a measuring mechanism 204, and the measuring mechanism 204 is driven to lift and lower via the measuring lifting assembly.

[0033] like Figures 2-3 As shown, in this embodiment, the clamping mechanism 107 in the avoidance clamping unit 1 includes a rotary drive motor 1071, a transmission assembly, and a pressure seat 1075. The pressure seat 1075 is driven to rotate by the rotary drive motor 1071, and the rotary drive motor 1071 transmits torque through the transmission assembly. A floating pressure head 1076 is provided inside the pressure seat 1075. When the invention is in operation, the avoidance clamping unit 1 is initially positioned at the upper end of the tilting frame 401. The lateral drive assembly first drives the clamping mechanism 107 to move laterally to avoid the placement of the pyrotechnic item 601, the compensation pad 602, and the housing 603. After the pyrotechnic item 601, the compensation pad 602, and the housing 603 are in place, the lateral drive assembly drives the clamping mechanism 107 to return to its original position so that the center of the pressure seat 1075 is aligned with the center of the upper closed end of the housing 603. Then, the clamping lifting assembly drives the pressure seat 1075 to descend and fit onto the end of the housing 603. The floating pressure head 1076 inside the pressure seat 1075... The moving pressure head 1076 presses the housing 603 to eliminate the gap between the inner bottom surface of the housing 603, the compensation pad 602, and the pyrotechnic item 601. The pressure seat 1075 is fitted onto the end of the housing 603 and can drive it to rotate. When measuring, the flipping frame 401 will flip 180°. At this time, the avoidance pressure unit 1 is located at the lower end of the flipping frame 401, and the pyrotechnic item 601 relies on its own weight to compact the compensation pad 602 to ensure measurement accuracy. The pressure seat 1075 drives the closed end of the housing 603 to rotate, thereby achieving the purpose of multi-point measurement in the circumferential direction at the open end of the upper housing 603.

[0034] like Figures 2-3 As shown, in this embodiment, the clamping and lifting assembly in the avoidance clamping unit 1 includes a clamping and lifting motor 101, a clamping and lifting screw 102, and a clamping and lifting seat 103, wherein the clamping and lifting seat 103 is slidably connected to the tilting frame 401, as shown.

Figures 2-3 As shown, the lower side of the pressing and lifting seat 103 is provided with a pressing and lifting slider 1031 that cooperates with the lifting slide rail 405. The pressing and lifting motor 101 and the pressing and lifting screw 102 are both provided on the tilting frame 401, and the pressing and lifting screw 102 is driven to rotate by the pressing and lifting motor 101. The lower side of the pressing and lifting seat 103 is provided with a pressing and lifting connecting seat, and the pressing and lifting connecting seat is provided with a pressing and lifting nut that is fitted onto the pressing and lifting screw 102. The pressing and lifting motor 101 drives the pressing and lifting screw 102 to rotate, thereby driving the pressing and lifting seat 103 to rise and fall.

[0035] like Figures 2-3 As shown, in this embodiment, the lateral drive assembly in the avoidance and pressing unit 1 includes a lateral drive motor 104, a lateral lead screw 105, and a lateral seat 106.

A spring 1078 is fitted on the pressure head shaft 1077, with one end of the spring 1078 abutting against the bottom surface of the pressure base 1075 and the other end abutting against the floating pressure head 1076. When the invention is working, as follows... Figure 1 As shown, the pressure base 1075 is fitted onto the closed end of the housing 603 of the product under test 6 and can drive the product under test 6 to rotate as a whole, so as to achieve the purpose of multi-point measurement by rotating the open end of the housing 603. The floating pressure head 1076 abuts against the housing 603 and presses it tightly. At the same time, the floating pressure head 1076 is a floating pressure, which can drive the pressure head shaft 1077 to float and move and compress the spring 1078 during the pressing process, thereby avoiding the danger of rigid contact between the floating pressure head 1076 and the product under test 6.

[0037] like Figures 4-5As shown, in this embodiment, the measuring lifting assembly in the measuring unit 2 includes a measuring lifting motor 201, a measuring lifting screw 202, and a measuring lifting seat 203. The measuring lifting seat 203 is slidably connected to the tilting frame 401. A measuring lifting slider 2031, cooperating with a lifting slide rail 405 on the tilting frame 401, is provided on the lower side of the measuring lifting seat 203. Both the measuring lifting motor 201 and the measuring lifting screw 202 are mounted on the tilting frame 401, and the measuring lifting screw 202 is driven to rotate by the measuring lifting motor 201. A measuring lifting connecting seat is provided on the lower side of the measuring lifting seat 203, and a measuring lifting nut is fitted onto the measuring lifting screw 202 within the measuring lifting connecting seat. The measuring mechanism 204 is located within the measuring lifting seat 203. Additionally, as shown... Figure 4 as well as Figures 1-2 As shown, both ends of the measuring lifting screw 202 and the pressing lifting screw 102 are provided with screw mounting blocks 2021 fixed on the flipping frame 401.

[0038] like Figures 4-5 As shown, in this embodiment, the measuring mechanism 204 includes a horizontal fine-tuning component 2049, a measuring cylinder 2046, a measuring sensor 2044, a floating connecting plate 2041, and a measuring pressure block 2043. The measuring pressure block 2043 is located on the front side of the floating connecting plate 2041, and the rear side of the floating connecting plate 2041 is floatingly connected to the power end of the measuring cylinder 2046. The measuring sensor 2044 is located on the rear side of the floating connecting plate 2041, and the measuring probe 20441 used in conjunction with the measuring sensor 2044 protrudes after passing through the floating connecting plate 2041 and the measuring pressure block 2043. The measuring cylinder 2046 is located on the horizontal fine-tuning component 2049, and the horizontal fine-tuning component 2049 is located in the measuring lifting seat 203.

[0039] like Figure 5As shown, the power end of the measuring cylinder 2046 is connected to a measuring movable seat 2045, and the measuring sensor 2044 is disposed in the measuring movable seat 2045. Floating guide columns 2047 are provided at both ends of the rear side of the floating connecting plate 2041, and guide blocks 20451 are provided at both ends of the front side of the measuring movable seat 2045. The rear end of the floating guide column 2047 is movably inserted into the corresponding guide block 20451. A floating spring 2048 is sleeved on the floating guide column 2047, and one end of the floating spring 2048 abuts against the floating connecting plate 2041, and the other end abuts against the guide block 20451. A limiting block is provided at the tail end of the floating guide column 2047 to prevent it from disengaging from the guide block 20451. During measurement, after the pyrotechnic item 601, compensation pad 602, and housing 603 are placed, they need to be pressed together to eliminate gaps. At this time, the upper end of the product under test 6 is elastically floated and pressed by the floating pressure head 1076 in the pressure seat 1075, while the lower end of the product under test 6 is elastically floated and pressed by the measuring pressure block 2043. The measuring moving seat 2045 is driven to move by the measuring cylinder 2046, thereby driving the measuring pressure block 2043 to enter the opening end on the lower side of the housing 603 and press the pyrotechnic item 601. The floating connecting plate 2041, floating guide post 2047, and floating... The structure, including the movable spring 2048, ensures elastic contact between the measuring pressure block 2043 and the pyrotechnic item 601, preventing rigid contact and collisions that could cause danger. During measurement, the flipping frame 401 rotates 180° so that the open end of the housing 603 faces upward. At this time, the measuring sensor 2044, in conjunction with the measuring probe 20441, detects whether the distance between the edge of the open end of the housing 603 and various points on the surface of the pyrotechnic item 601 meets the requirements, that is, whether the depth value of the pyrotechnic item 601 within the housing 603 meets the requirements. Furthermore, during measurement, the measuring cylinder 2046 can apply different pressures depending on the specific product. The measuring sensor 2044 is a known technology in the art and is a commercially available product.

[0040] In addition to utilizing the aforementioned pressure seat 1075 to drive the overall rotation of the product under test 6 to achieve multi-point measurement in the circumferential direction, this invention can also achieve multi-point measurement in the horizontal direction by driving the position of the measuring probe 20441 along the horizontal degree of freedom through the horizontal fine-tuning component 2049.

[0044] The working principle of this invention is as follows:

[0045] like Figure 1 and Figure 8 As shown, the product to be tested 6 of this invention includes a pyrotechnic component 601, a compensation pad 602, and a housing 603.

When the invention starts working, the avoidance and clamping unit 1 is located at the upper end of the tilting frame 401, and the measuring unit 2 is located at the lower end of the tilting frame 401. The clamping mechanism 107 in the avoidance and clamping unit 1 is driven to move laterally to an avoidance position by the lateral drive assembly. Then, the pyrotechnic component 601 is first placed on the support sleeve 205 on the upper side of the measuring lifting seat 203. Next, the compensation pad 602 is placed on top of the pyrotechnic component 601, and then the housing 603 is fitted onto the compensation pad 602 and the pyrotechnic component 601. Then, the clamping mechanism 107 in the avoidance and clamping unit 1 is driven to move above the housing 603 by the lateral drive assembly. Then, the clamping mechanism 107 is driven to descend by the clamping lifting assembly, and the pressure seat 1075 of the clamping mechanism 107 is fitted onto the housing. At the closed end of the upper side of the body 603, the floating pressure head 1076 in the pressure seat 1075 elastically presses the housing 603, while the measuring pressure block 2043 in the measuring mechanism 204 rises into the open end of the lower side of the housing 603 and elastically presses the pyrotechnic item 601. The above process is to eliminate the gap between the bottom surface of the housing 603, the compensation pad 602 and the pyrotechnic item 601, and to prevent rigid contact from causing danger during the pressing process. Then, the flipping frame 401 of the flipping unit 4 flips 180° so that the open end of the housing 603 faces upward. At this time, the weight of the pyrotechnic item 601 is applied to the compensation pad 602 to ensure compaction, thereby ensuring accurate measurement. Then, the measuring sensor 2044 in the measuring mechanism 204 uses the measuring probe 20441 to measure the distance between multiple points between the open end face of the housing 603 and the surface of the pyrotechnic item 601, thereby determining whether the depth value of the pyrotechnic item 601 after being installed in the housing 602 meets the process requirements.

[0046] This invention can achieve multi-point measurement in both the circumferential and horizontal directions. The limiting and moving component 2049 in the measuring mechanism 204 can adjust the horizontal degree of freedom of the measuring block 2043. This not only ensures that the measuring block 2043 and the measuring probe 20441 can be aligned with the product under test 6 and enter the open end of the housing 603, but also allows for fine-tuning of the horizontal movement of the measuring block 2043 and the measuring probe 20441, thereby achieving multi-point measurement in the horizontal direction. Meanwhile, the pressing seat 1075 in the pressing mechanism 107 locks the closed end of the housing 603 and can drive the entire product under test 6 to rotate, thereby achieving multi-point measurement in the circumferential direction.

[0047] When placing the pyrotechnic item 601, the compensation pad 602, and the housing 603, the clamping mechanism 107 in the avoidance clamping unit 1 is driven to move laterally to the avoidance position by the lateral drive assembly, so that there will be no interference affecting the placement. When measuring, the anti-tipping unit 3 is provided on both sides of the middle of the flipping frame 401 to clamp the product to be measured 6 to prevent it from tipping over, thereby ensuring the smooth progress of the measurement.

[0048] The present invention can meet the measurement requirements of products of different specifications. The clearance clamping unit 1 and the measuring unit 2 can be raised and lowered to change the distance between them, thereby adapting to the measurement needs of products of different lengths. The measuring pressure block 2043 can apply different measuring pressures according to the actual product specifications through the measuring cylinder 2046.
