Description

Technical Field

[0002] Automobile safety has always been a factor that car buyers attach great importance to. The number and type of airbags are directly related to the performance of the passive safety of the car. As a curtain airbag that protects people in the event of a vehicle rollover, its core component is the hybrid gas generator. Different from the traditional pyrotechnic gas generator, the hybrid gas generator requires the high-pressure mixed gas to be filled into a sealed cylinder in advance, and the sealing of the cylinder is inseparable from the welding process.

[0060] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0061] Please refer to Figure 1 and Figure 2 , this embodiment provides a cylinder rust removal device 100, the cylinder rust removal device 100 includes a workbench 110, a clamping assembly 130, a movable assembly 150 and a rust removal assembly 170;

[0062] The clamping assembly 130 is connected to the workbench 110, and the clamping assembly 130 is used to clamp the cylinder 10 to be derusted; the movable assembly 150 is movably connected to the workbench 110, and the derusting assembly 170 is connected to the movable assembly 150;

[0063] The movable component 150 is used to drive the rust removal component 170 to move in at least one direction in the space relative to the cylinder 10 clamped by the clamping component 130 to remove rust from the end surface, inner wall or outer wall of the cylinder 10 .

[0064] Please refer to Figure 1 and Figure 2 The working principle of the cylinder rust removal device 100 is:

[0065] The cylinder rust removal device 100 includes a workbench 110, a clamping assembly 130, a movable assembly 150 and a rust removal assembly 170;

[0066] The clamping assembly 130 is connected to the workbench 110, and is used to clamp the cylinder 10 to be derusted; and in the process of clamping, the clamping assembly 130 can adapt to the clamping work of cylinders 10 with various size parameters; in addition, in the process of use, it can also clamp other structures other than the cylinder 10, thereby expanding its scope of use in this way;

[0067] The movable assembly 150 is movably connected to the workbench 110, and the rust removal assembly 170 is connected to the movable assembly 150, and the movable assembly 150 is used to drive the rust removal assembly 170 to move in at least one direction in the space relative to the cylinder 10 clamped by the clamping assembly 130, so as to remove rust from the end face, inner wall or outer wall of the cylinder 10; thus, through such an arrangement, the rust removal assembly 170 can move in the space relative to the cylinder 10 clamped by the clamping assembly 130 during use under the action of the movable assembly 150, and then adjust the relative position of the rust removal assembly 170 relative to the cylinder 10, thereby realizing multi-position rust removal of the cylinder 10, that is, the end face, inner wall or outer wall of the cylinder 10 can be rust removed;

[0068] In summary, the cylinder rust removal device 100 can flexibly adjust the position of the rust removal component 170 in space through the setting of the movable component 150, thereby improving its flexibility and expanding its rust removal range, so it can realize multi-position rust removal of the cylinder 10; and during its use, it adopts a method of separately setting the rust removal component 170 and the clamping component 130. In this way, it can adapt to the clamping requirements of various sizes and structures based on the clamping of the clamping component 130, and then it can adapt to the rust removal work of cylinders 10 with multiple diameter ranges based on the expansion of its clamping range; and the cylinder rust removal device 100 has a simple overall structure and is flexible and convenient to operate, which can reduce the labor intensity of the staff while improving the rust removal efficiency.

[0069] For further information, please refer to Figure 1-Figure 5 In this embodiment, when the clamping assembly 130 is configured, its function is to complete the clamping work of the cylinder 10. Based on this, it can adopt a claw-type chuck setting method. Specifically, the clamping assembly 130 includes a clamping shell 131, a spiral wheel 132, at least one adjusting wheel 133, a clamping motor 134 and a plurality of clamping chucks 135; the spiral wheel 132 is rotatably connected to the clamping shell 131; the adjusting wheel 133 is rotatably connected to the clamping shell 131 and meshes with the spiral wheel 132; all the clamping chucks 135 are slidably connected to the clamping shell 131 along the radial direction of the spiral wheel 132, and all the clamping chucks 135 are threadedly matched with the spiral wheel 132; the clamping motor 134 is connected to the clamping shell 131, and the clamping motor 134 is transmission-connected to at least one of the adjusting wheels 133 through an adjuster.

[0070] Therefore, when it is necessary to clamp the cylinder 10, taking the process of clamping the cylinder 10 as an example, the clamping motor 134 works, thereby driving the adjusting wheel 133 to rotate, and the adjusting wheel 133 is engaged with the spiral wheel 132, so that the spiral wheel 132 can be driven to rotate around its axis, and then the clamping chuck 135 matched with the spiral wheel 132 can be driven to move along its radial direction, so that the clamping work of the cylinder 10 can be completed by the movement of the clamping chuck 135; in the aforementioned process, since multiple clamping chucks 135 are all matched with the same spiral wheel 132, they are synchronized with each other in relative movement; and when configuring the adjusting wheel 133, multiple adjusting wheels 133 can be set, and multiple adjusting wheels 133 are distributed around the axis of the spiral wheel 132, and the clamping motor 134 can be matched with one of the adjusting wheels 133.

[0071] Among them, when configuring the spiral wheel 132, along its axis, the two sides thereof are respectively provided with teeth cooperating with the adjustment wheel 133 and threads cooperating with the clamping chuck 135, and when configuring the aforementioned clamping housing 131 and the spiral wheel 132, they are jointly formed with a channel for the cylinder 10 to be derusted to pass through, the purpose of which is to reduce the difficulty of installation and improve the flexibility of the clamping process. It should be noted that in this embodiment, the clamping assembly 130 adopts a configuration mode of configuring three clamping chucks 135, and its function is roughly the same as the function principle of the automatic self-aligning three-jaw chuck in the prior art, so it is not repeated here.

[0072] Further, it can be seen from the above content that in this embodiment, the rust removal of the cylinder 10 of the hybrid gas generator is taken as an example for explanation. Based on this, there is a need for rust removal at both ends of the cylinder 10. Therefore, in order to improve the rust removal efficiency and flexibility in the rust removal process;

[0073] Therefore, please refer to Figure 1-Figure 6 In this embodiment, the clamping assembly 130 is capable of adjusting the clamped cylinder 10. Specifically, the clamping assembly 130 further includes a gear box 136, a rotating table 137 and a rotating motor 138.

[0074] The gear box 136 is connected to the workbench 110 , the rotating table 137 is connected to the rotating motor 138 through the gear box 136 , and the rotating table 137 is connected to the clamping housing 131 ;

[0075] The axial direction of the cylinder 10 clamped by the clamping assembly 130 is the first direction, the rotational axis direction of the rotating table 137 is the second direction, and the first direction is perpendicular to the second direction.

[0076] Therefore, through the above-mentioned structural arrangement, the rotating table 137 can be driven to rotate by the rotating motor 138 through the gear box 136, so that the position of the cylinder 10 can be adjusted. Moreover, during the rotation, the rotation axis direction of the rotating table 137 is the second direction, and the axis direction of the cylinder 10 clamped by the clamping assembly 130 is the first direction, and the first direction is perpendicular to the second direction. Therefore, when the rotating motor 138 is running and the rotating table 137 is driven to rotate 180 degrees through the gear box 136, the cylinder 10 can be turned around, and then after the rust removal work is completed at one end, the other end of the cylinder 10 can be quickly turned to a position where rust removal can be performed through the action of the aforementioned rotating motor 138.

[0077] It should be noted that when the above-mentioned rotating motor 138 notifies and drives the cylinder 10 to change direction, the spatial position of the rust removal component 170 needs to be adjusted through the movable component 150. The purpose is to avoid the movable component 150 and the rust removal component 170 being within the active radius of the clamping component 130 and the cylinder 10, so as to avoid the clamping component 130 and the cylinder 10 from interfering with the movable component 150 or the rust removal component 170 during rotation.

[0078] When the gear box 136 is configured, its function is to transmit the power of the rotating motor 138 to the rotating table 137. When the gear box 136 is configured, the gear box 136 may include a housing 139, a support shaft 141, a transmission turbine 142, a mounting bearing 143, a coupling 144 and a transmission worm 145;

[0079] The support shaft 141 is disposed in the housing 139, the transmission turbine 142 is rotatably connected to the support shaft 141 through the mounting bearing 143, and the transmission turbine 142 is connected to the rotating table 137; the coupling 144 and the transmission worm 145 are both disposed in the housing 139;

[0080] The main shaft of the rotary motor 138 is connected to the driving worm 145 via a coupling 144 .

[0081] Therefore, through the above-mentioned structural setting, when the rotating motor 138 is started, the transmission worm 145 can be driven to rotate through the coupling 144, and when the transmission worm 145 rotates, the transmission turbine 142 matched with the transmission worm 145 is driven to rotate, thereby driving the rotating table 137 connected to the transmission turbine 142 to rotate, and the rotating table 137 is connected to the clamping transmission turbine 142, so that the rotation stability and the accuracy of rotation control can be improved in this way.

[0082] For further information, please refer to Figure 7-Figure 9 , and combined with Figure 1-Figure 5As can be seen from the above content, in this embodiment, the purpose of driving the rust removal component 170 to move in space by the movable component 150 is to adapt to the rust removal needs of different types of structures. Taking the structure to be rusted as the cylinder 10 as an example, the device can remove rust from the end face, outer peripheral surface and inner wall of the cylinder 10. Based on this, in order to enable it to remove rust from the outer peripheral surface and inner wall at different positions, it is necessary to enable the rust removal component 170 to move along the axis of the cylinder 10 and also move along the radial direction of the cylinder 10. Based on this, in this embodiment, the movable component 150 can move along the axis direction and radial direction of the cylinder 10 as an example for explanation. Specifically, the axis direction of the cylinder 10 clamped by the clamping component 130 is the first direction;

[0083] The movable assembly 150 includes a first movable mechanism 151, a first movable platform 152, a second movable mechanism 153 and a second movable platform 154;

[0084] The first moving mechanism 151 is connected to the workbench 110, the first movable platform 152 is transmission-connected to the first moving mechanism 151, and the first moving mechanism 151 is used to drive the first movable platform 152 to move along the first direction;

[0085] The second moving mechanism 153 is connected to the first movable platform 152, and the second movable platform 154 is transmission-connected to the second moving mechanism 153, and the second moving mechanism 153 is used to drive the second movable platform 154 to move along a second direction perpendicular to the first direction;

[0086] The rust removal assembly 170 is connected to the second movable platform 154 .

[0087] Therefore, through the above-mentioned structural setting, the first moving mechanism 151 and the second moving mechanism 153 can cooperate with each other to drive the rust removal component 170 connected to the second movable platform 154 to change its position along the first direction or the second direction.

[0088] It should be noted that, in this embodiment, the axial direction of the cylinder 10 clamped by the clamping assembly 130 is the first direction, which means that when the cylinder 10 clamped by the clamping assembly 130 is in a position opposite to the movable assembly 150, the axial direction of the cylinder 10 coincides with the movable direction of the first moving mechanism 151, and both are the first direction.

[0089] When configuring the first moving mechanism 151 and the second moving mechanism 153, this embodiment adopts the method of using a screw moving module for both the first moving mechanism 151 and the second moving mechanism 153. Specifically, the first moving mechanism 151 includes a first mounting seat 155, a first guide rod 156, a first screw 157 and a first screw motor 158; the first mounting seat 155 is connected to the workbench 110; the first guide rod 156 is connected to the first mounting seat 155, the first screw 157 is rotatably connected to the first mounting seat 155, and the first guide rod 156 and the first screw 157 both extend in the first direction; the first screw motor 158 is connected to the first mounting seat 155 and is transmission-connected to the first screw 157; the first movable platform 152 is slidably matched with the first guide rod 156 and is threadedly connected to the first screw 157.

[0090] The second moving mechanism 153 includes a second mounting seat 159, a second guide rod 161, a second lead screw 162 and a second lead screw motor 163; the second mounting seat 159 is connected to the first movable platform 152; the second guide rod 161 is connected to the second mounting seat 159, the second lead screw 162 is rotatably connected to the second mounting seat 159, and the second guide rod 161 and the second lead screw 162 both extend along the second direction; the second lead screw motor 163 is connected to the second mounting seat 159 and is transmission-connected to the second lead screw 162; the second movable platform 154 is slidably matched with the second guide rod 161 and is threadedly connected to the second lead screw 162.

[0091] Therefore, through the above-mentioned structural setting, based on the operation of the first screw motor 158 and the second screw motor 163, the first screw 157 and the second screw 162 are driven to rotate, thereby driving the first movable platform 152 to move along the first guide rod 156 and driving the second movable platform 154 to move along the second guide rod 161, and the movement in the two directions can be a separate movement or a compound movement, and the specific movement can be controlled and adjusted according to actual needs to control the first screw motor 158 and the second screw motor 163.

[0092] For further information, please refer to Figure 10-13 , and combined with Figure 1-Figure 9 In this embodiment, when the rust removal component 170 is configured, its function is to remove rust. Based on this, the rust removal component 170 includes a rotating motor 171, a transmission mechanism 172, a sealing cover 173 and a rust removal terminal;

[0093] The rotating motor 171 is connected to the second movable platform 154; the transmission mechanism 172 is connected to the main shaft of the sealing cover 173 and the rotating motor 171, and the rust removal terminal is connected to the sealing cover 173. Therefore, on the basis of being connected to the second movable platform 154, the second movable platform 154 can change its position in the space along the first direction and the second direction under the driving action of the first screw motor 158 and the second screw motor 163, and in this process, the sealing cover 173 is driven to rotate by the rotating motor 171, thereby driving the rust removal terminal connected to the sealing cover 173 to rotate, so that the rust removal terminal contacts the position to be rusted and removes the rust; it should be noted that when configuring the rust removal terminal, it can adopt the rust removal blade or rust removal brush in the prior art, or other structural parts that can be used for rust removal.

[0094] In this embodiment, when the transmission mechanism 172 is configured, its function is to drive the sealing cover 173 to rotate; specifically, the transmission mechanism 172 includes a connecting member 174, a connecting bearing, a planetary carrier 175, a sun gear 176, a ring gear 177 and a plurality of planetary gears 178; the connecting member 174 is fixedly connected to the rotating motor 171, the planetary carrier 175 is connected to the connecting member 174, and the plurality of planetary gears 178 are rotatably connected to the planetary carrier 175; the sun gear 176 is connected to the main shaft of the rotating motor 171, and the sealing cover 173 is connected to the main shaft of the rotating motor 171 through a connecting bearing; the ring gear 177 is connected to the sealing cover 173; the plurality of planetary gears 178 are arranged at intervals on the outer periphery of the sun gear 176 around its axis and mesh with the sun gear 176; the ring gear 177 is located on the periphery of the plurality of planetary gears 178 and meshes with all the planetary gears 178.

[0095] Therefore, through such a setting, the rust removal mechanism realizes fixed-axis rotation based on the planetary gear 178 mechanism, and the rust removal terminal is fixed to the sealing cover 173 by the hexagon socket bolts evenly distributed at 120°, and then the sun gear 176 can be driven to rotate by the rotation of the rotating motor 171, and multiple planetary gears 178 are meshed with the sun gear 176 and the ring gear 177, and then when the sun gear 176 rotates and drives the planetary gear 178 to rotate, it can drive the ring gear 177 to rotate, and since the ring gear 177 is connected to the sealing cover 173, and the rust removal terminal is connected to the sealing cover 173, therefore, when the sealing cover 173 rotates, it can drive the rust removal terminal to rotate, and then when it moves to the rust removal position, the rust removal work can be completed.

[0096] On the basis of the above structure, since the inner wall of the cylinder 10 needs to be derusted, in order to facilitate the insertion into the cylinder 10, the derusting assembly 170 further includes an adjusting rod 179, which is connected to the second movable platform 154 and the rotating motor 171. Through the setting of the adjusting rod 179, one end of the adjusting rod 179 is connected to the rotating motor 171, and the other end of the adjusting rod 179 is connected to the clamp 181 on the second movable platform 154, so that the adjusting rod 179 can be detachably set, or set as a telescopic rod, and then by adjusting the length of the adjusting rod 179, the spacing distance between the derusting assembly 170 and the second movable platform 154 can be adjusted, so as to adapt to different requirements for derusting the inner wall of the cylinder 10.

[0097] Please refer to Figure 1-Figure 13 The cylinder rust removal device 100 includes the above-mentioned clamping assembly 130, movable assembly 150 and rust removal assembly 170; wherein the clamping assembly 130 and movable assembly 150 are connected to the workbench 110 by bolts; and the rust removal assembly 170 is connected to the second movable platform 154 of the movable assembly 150 by a fixed sleeve and screws; the cylinder 10 to be rusted is radially positioned by an automatic self-aligning three-jaw chuck, and axially positioned according to the press-fit depth of the parts at both ends, that is, clamped to the clamping assembly 130; and the lower part of the clamping assembly 130 adopts a worm gear mechanism to drive the clamped cylinder 10 to rotate, thereby adjusting the direction of the cylinder 10; the cooperation between the lead screw of the movable assembly 150 and the lead screw motor can drive the rust removal assembly 170 to move in two directions; the rust removal assembly 170 realizes fixed-axis rotation based on the planetary gear 178 mechanism, and the rust removal terminal is fixed to the sealing cover 173 by 120° uniformly distributed hexagon socket bolts.

[0098] Therefore, the cylinder rust removal device 100 can realize rapid, efficient and dead-angle rust removal inside and outside the two ends of the cylinder 10 according to the geometric dimensions of the cylinder 10 and the press-fitting and welding process of the generator, and can separately treat the rusted parts at both ends of the high-pressure cylinder 10 according to the actual rust location, which is suitable for rapid and dead-angle rust removal at both ends of the hybrid high-pressure cylinder 10. The rust removal terminals of the rust removal assembly 170 are easy to disassemble and assemble, and can be adapted to high-pressure cylinders 10 of various diameters; it greatly reduces manpower, can realize assembly line operation, and has high operating efficiency.
