[0060] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

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

[0062] Clamping assembly 130 is connected with workbench 110, and clamping assembly 130 is used to clamp the cylinder 10 to be rusted;Movable assembly 150 is movably connected with workbench 110, and rust removal assembly 170 is connected with movable assembly 150;

[0063] Wherein, movable assembly 150 is used to drive rust removal assembly 170 to move in space along at least one direction relative to the cylinder 10 clamped by clamping assembly 130, to remove rust on the end face, 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 workbench 110, clamping assembly 130, movable assembly 150 and rust removal assembly 170;

[0066] The clamping assembly 130 is connected with the workbench 110, and is used for clamping the cylinder 10 to be derusted. In addition, the clamping assembly 130 can adapt to clamping work of the cylinder 10 with various size parameters during clamping. In addition, the clamping assembly 130 can also clamp other structures other than the cylinder 10 during use, thereby expanding the use range.

[0067] The movable assembly 150 is movably connected with the workbench 110, and the derusting assembly 170 is connected with the movable assembly 150. The movable assembly 150 is used for driving the derusting assembly 170 to move in at least one direction relative to the cylinder 10 clamped by the clamping assembly 130 in space, so as to derust the end face, inner wall or outer wall of the cylinder 10. Thus, the derusting assembly 170 can move relative to the cylinder 10 clamped by the clamping assembly 130 in space under the action of the movable assembly 150 during use, thereby adjusting the relative position of the derusting assembly 170 relative to the cylinder 10. Thus, multi-position derusting of the cylinder 10 can be realized, that is, the end face, inner wall or outer wall of the cylinder 10 can be derusted.

[0068] In summary, the cylinder derusting device 100 can flexibly adjust the position of the derusting assembly 170 in space through the movable assembly 150, thereby improving the flexibility and expanding the derusting range. Thus, multi-position derusting of the cylinder 10 can be realized. In addition, the derusting assembly 170 and the clamping assembly 130 are separately arranged during use. Through this way, the clamping assembly 130 can adapt to clamping requirements of various sizes and structures based on clamping, thereby expanding the clamping range and adapting to derusting work of the cylinder 10 with various diameters. In addition, the cylinder derusting device 100 has simple structure and flexible operation, thereby reducing the labor intensity of workers and improving the derusting efficiency.

[0069] Further, please refer to Figures 1-5In the embodiment, when the clamping assembly 130 is configured, it plays a role in completing the clamping work of the cylinder 10, and based on this, it can adopt the setting mode of the jaw chuck, specifically, the clamping assembly 130 comprises a clamping shell 131, a spiral wheel disc 132, at least one adjusting wheel 133, a clamping motor 134 and a plurality of clamping chucks 135; the spiral wheel disc 132 is rotatably connected with the clamping shell 131; the adjusting wheel 133 is rotatably connected with the clamping shell 131 and is engaged with the spiral wheel disc 132; all the clamping chucks 135 are slidably connected with the clamping shell 131 along the radial direction of the spiral wheel disc 132, and all the clamping chucks 135 are threadedly engaged with the spiral wheel disc 132; the clamping motor 134 is connected with the clamping shell 131, and the clamping motor 134 is drivingly connected with at least one adjusting wheel 133 through an adjuster.

[0070] Therefore, when the cylinder 10 needs to be clamped, taking the process of clamping the cylinder 10 as an example, the clamping motor 134 is operated to drive the adjusting wheel 133 to rotate, and the adjusting wheel 133 is engaged with the spiral wheel disc 132, so that the spiral wheel disc 132 can be driven to rotate around its axis, and the clamping chuck 135 engaged with the spiral wheel disc 132 can be driven to move along its radial direction, so that the clamping work of the cylinder 10 can be completed through the movement of the clamping chuck 135; in the foregoing process, since the plurality of clamping chucks 135 are engaged with the same spiral wheel disc 132, they are synchronized relative to movement; and when the adjusting wheel 133 is configured, a plurality of adjusting wheels 133 can be distributed around the axis of the spiral wheel disc 132, and the clamping motor 134 can be engaged with one of the adjusting wheels 133.

[0071] In the embodiment, when the clamping assembly 130 is configured, it plays a role in completing the clamping work of the cylinder 10, and based on this, it can adopt the setting mode of the jaw chuck, specifically, the clamping assembly 130 comprises a clamping shell 131, a spiral wheel disc 132, at least one adjusting wheel 133, a clamping motor 134 and a plurality of clamping chucks 135; the spiral wheel disc 132 is rotatably connected with the clamping shell 131; the adjusting wheel 133 is rotatably connected with the clamping shell 131 and is engaged with the spiral wheel disc 132; all the clamping chucks 135 are slidably connected with the clamping shell 131 along the radial direction of the spiral wheel disc 132, and all the clamping chucks 135 are threadedly engaged with the spiral wheel disc 132; the clamping motor 134 is connected with the clamping shell 131, and the clamping motor 134 is drivingly connected with at least one adjusting wheel 133 through an adjuster.

[0072] Further, from the above content, it can be known that in the embodiment, the cylinder 10 of the hybrid gas generator is taken as an example to be rusted, based on this, the both ends of the cylinder 10 have the need to be rusted, so that the rusting efficiency and the flexibility in the rusting process can be improved.

[0073] Therefore, please refer to Figures 1-6The embodiment adopts a mode that the clamping assembly 130 can adjust the clamped cylinder 10. Specifically, the clamping assembly 130 further comprises a gear box 136, a rotating table 137 and a rotating motor 138.

[0074] The gear box 136 is connected with the workbench 110, the rotating table 137 is drivingly connected with the rotating motor 138 through the gear box 136, and the rotating table 137 is connected with the clamping shell 131.

[0075] The axis direction of the cylinder 10 clamped by the clamping assembly 130 is the first direction, the rotating 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 structure, 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, in the rotating process, the rotating 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, which is perpendicular to the second direction. Therefore, when the rotating motor 138 operates and drives the rotating table 137 to rotate 180 degrees through the gear box 136, the cylinder 10 can be adjusted to change the direction, so that after the rust removal work is completed at one end of the cylinder 10, the other end of the cylinder 10 can be quickly adjusted to the position for rust removal through the action of the rotating motor 138.

[0077] It should be noted that when the rotating motor 138 drives the cylinder 10 to change the direction, the spatial position of the rust removal assembly 170 needs to be adjusted by the movable assembly 150. The purpose is to avoid the movable assembly 150 and the rust removal assembly 170 being in the activity radius of the clamping assembly 130 and the cylinder 10, so as to avoid the motion interference between the clamping assembly 130 and the cylinder 10 and the movable assembly 150 or the rust removal assembly 170 when rotating.

[0078] When the gear box 136 is configured, the 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 can comprise a box body 139, a support shaft 141, a transmission turbine 142, a mounting bearing 143, a shaft coupling 144 and a transmission worm 145.

[0079] The support shaft 141 is arranged in the box body 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 with the rotating table 137. The shaft coupling 144 and the transmission worm 145 are arranged in the box body 139.

[0080] The main shaft of the rotating motor 138 is drivingly connected with the transmission worm 145 through the shaft coupling 144.

[0081] Therefore, through the above structural arrangement, when the rotating motor 138 is started, the transmission worm 145 is driven to rotate by the coupling 144, and in turn, the transmission turbine 142 cooperating with the transmission worm 145 is driven to rotate, thereby driving the rotating table 137 connected with the transmission turbine 142 to rotate. The rotating table 137 is connected with the clamped transmission turbine 142, and in turn, the rotating stability and the rotation control precision can be improved through the above manner.

[0082] Further, please refer to Figures 7-9 , and in combination with Figures 1-5 From the above, in the present embodiment, the purpose of driving the rust removal assembly 170 to move in space by the movable assembly 150 is to adapt to the rust removal requirements of different types of structures. For example, the structure to be rusted is the cylinder 10. The device can rust the end face, outer peripheral surface and inner wall of the cylinder 10. In order to rust the outer peripheral surface and inner wall at different positions, the rust removal assembly 170 needs to be able to move along the axis of the cylinder 10 and also move along the radial direction of the cylinder 10. Therefore, in the present embodiment, the movable assembly 150 is taken as an example to move along the axis and radial direction of the cylinder 10. Specifically, the axis direction of the cylinder 10 clamped by the clamped assembly 130 is the first direction.

[0083] The movable assembly 150 includes a first moving mechanism 151, a first movable table 152, a second moving mechanism 153 and a second movable table 154.

[0084] The first moving mechanism 151 is connected with the workbench 110. The first movable table 152 is in transmission connection with the first moving mechanism 151, and the first moving mechanism 151 is used to drive the first movable table 152 to move along the first direction.

[0085] The second moving mechanism 153 is connected with the first movable table 152. The second movable table 154 is in transmission connection with the second moving mechanism 153, and the second moving mechanism 153 is used to drive the second movable table 154 to move along the second direction perpendicular to the first direction.

[0086] The rust removal assembly 170 is connected with the second movable table 154.

[0087] Therefore, through the above structural arrangement, the first moving mechanism 151 and the second moving mechanism 153 can cooperate with each other, and in turn, drive the rust removal assembly 170 connected with the second movable table 154 to change position along the first direction or the second direction.

[0088] It should be noted that in the embodiment, the axis 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 directly opposite the movable assembly 150, the axis direction of the cylinder 10 coincides with the moving 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, the embodiment adopts a mode in which the first moving mechanism 151 and the second moving mechanism 153 are both screw moving modules. 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 with the workbench 110. The first guide rod 156 is connected with the first mounting seat 155, and the first screw 157 is rotatably connected with the first mounting seat 155. Both the first guide rod 156 and the first screw 157 extend along the first direction. The first screw motor 158 is connected with the first mounting seat 155 and is in transmission connection with the first screw 157. The first movable table 152 is slidably matched with the first guide rod 156 and is in threaded connection with the first screw 157.

[0090] The second moving mechanism 153 includes a second mounting seat 159, a second guide rod 161, a second screw 162, and a second screw motor 163. The second mounting seat 159 is connected with the first movable table 152. The second guide rod 161 is connected with the second mounting seat 159, and the second screw 162 is rotatably connected with the second mounting seat 159. Both the second guide rod 161 and the second screw 162 extend along the second direction. The second screw motor 163 is connected with the second mounting seat 159 and is in transmission connection with the second screw 162. The second movable table 154 is slidably matched with the second guide rod 161 and is in threaded connection with the second screw 162.

[0091] Therefore, 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 can be driven to rotate, thereby driving the first movable table 152 to move along the first guide rod 156 and driving the second movable table 154 to move along the second guide rod 161. The movement in the two directions can be independent movement or combined movement, and the specific movement can be adjusted by controlling the first screw motor 158 and the second screw motor 163 according to actual needs.

[0092] Further, please refer to Figures 10-13 , and in combination with Figures 1-9 , in the embodiment, when configuring the rust removal assembly 170, the rust removal assembly 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 with the second movable table 154; the transmission mechanism 172 is in transmission connection with the sealing cover 173 and the main shaft of the rotating motor 171, and the rust removal terminal is connected with the sealing cover 173. Thus, on the basis of being connected with the second movable table 154, the second movable table 154 can be moved in the space along the first direction and the second direction under the driving action of the first lead screw motor 158 and the second lead screw motor 163, and in this process, the sealing cover 173 is driven to rotate by the rotating motor 171, so as to drive the rust removal terminal connected with the sealing cover 173 to rotate, so as to contact the rust removal terminal with the position to be removed rust, and remove the rust; it should be noted that in the configuration of the rust removal terminal, the rust removal blade or the rust removal brush in the prior art can be used, or other structure capable of removing rust can be used.

[0094] In the embodiment, in the configuration of the transmission mechanism 172, the transmission mechanism 172 drives the sealing cover 173 to rotate; specifically, the transmission mechanism 172 includes a connecting piece 174, a connecting bearing, an planet carrier 175, a sun gear 176, a ring gear 177 and a plurality of planet gears 178; the connecting piece 174 is fixedly connected with the rotating motor 171, the planet carrier 175 is connected with the connecting piece 174, and the plurality of planet gears 178 are rotatably connected with the planet carrier 175; the sun gear 176 is connected with the main shaft of the rotating motor 171, the sealing cover 173 is connected with the main shaft of the rotating motor 171 through the connecting bearing; the ring gear 177 is connected with the sealing cover 173; the plurality of planet gears 178 are arranged at the outer periphery of the sun gear 176 and are in meshing connection with the sun gear 176; the ring gear 177 is located at the outer periphery of the plurality of planet gears 178 and is in meshing connection with all the planet gears 178.

[0097] Please refer to Figures 1-13 The cylinder derusting device 100 includes the clamping assembly 130, the movable assembly 150 and the derusting assembly 170 described above; wherein the clamping assembly 130 and the movable assembly 150 are connected to the workbench 110 by bolts; and the derusting assembly 170 is connected to the second movable table 154 of the movable assembly 150 by a fixed sleeve and a screw; the cylinder 10 to be derusted is radially positioned by the automatic self-centering three-jaw chuck, and is axially positioned according to the pressing depth of the two end components, 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, so that the direction of the cylinder 10 can be adjusted; the cooperation of the lead screw and the lead screw motor of the movable assembly 150 can drive the derusting assembly 170 to move in two directions; the derusting assembly 170 realizes fixed shaft rotation based on the planetary gear 178 mechanism, and the derusting terminals are fixed on the sealing cover 173 by 120° uniformly distributed internal hexagonal bolts.

[0098] Therefore, the cylinder derusting device 100 can realize fast, efficient and dead angle free derusting of the inside and outside of the two ends of the cylinder 10 according to the geometric size of the cylinder 10 and the generator pressing and welding process, and can separately process the rusted parts of the two ends of the high pressure cylinder 10 according to the actual rusted position, is suitable for fast and dead angle free derusting of the two ends of the mixed type high pressure cylinder 10, the derusting terminals of the derusting assembly 170 are convenient to disassemble and assemble, and can adapt to high pressure cylinders 10 of various diameters; greatly reduces the manpower, and can realize flow operation, high operation efficiency.
