[0021] Please refer to the following: Figures 1 to 8 The fixture for processing the outer casing of a power bank, provided in this embodiment of the invention, will now be described. Please refer to the following for further details. Figure 1 , Figure 2 , Figure 3 and Figure 8The fixture for processing power bank casing parts provided in this embodiment of the utility model includes a fixing component 1 and a fixture body 2. The fixing component 1 includes a mounting base 11, multiple support columns 12, and multiple bolts. The mounting base 11 is used to be fixedly installed on the processing platform of the power bank casing processing equipment. The multiple support columns 12 are vertically and spaced apart on the mounting base 11. The mounting base 11 is provided with multiple through holes 13 for bolts to pass through. The multiple bolts are used to fix the mounting base 11 to the processing platform of the power bank casing processing equipment. The fixture body 2 includes a fixture seat 21, two first inner support components 22, two second inner support components 23, a first actuator 24, a second actuator 25, a sliding shaft 26, and a drive mechanism 27. The fixture seat 21 is fixedly connected to the top ends of the multiple support columns 12. The two first inner support components 22 are movably disposed on the fixture seat 21 and are arranged in pairs along the left-right direction. The two second inner support components 23 are movably disposed on the fixture seat 21 and are arranged in pairs along the front-back direction. The first actuator 24 can actuate the two first inner support components 22 to move away from each other to expand the corresponding inner sidewalls of the power bank shell 6. The second actuator 25 can actuate the two second inner support components 23 to move away from each other to expand the corresponding inner sidewalls of the power bank shell 6. The sliding shaft 26 is slidably mounted on the clamp seat 21 in the vertical direction. The first actuator 24 and the second actuator 25 are fixedly mounted on the sliding shaft 26. The drive mechanism 27 is fixedly mounted on the mounting base 11. When the drive mechanism 27 drives the sliding shaft 26 to move axially, the sliding shaft 26 drives the first actuator 24 and the second actuator 25 to move. The first actuator 24 is a first wedge block with a first inclined surface 241 on each of its two opposite sides. Two first inner support components 22 are symmetrically arranged on both sides of the first wedge block with the first inclined surface 241. Each of the two first inner support components 22 has a second inclined surface 2221 that slides in contact with the first inclined surface 241. The slope direction of each first inclined surface 241 is opposite to that of the corresponding second inclined surface 2221. With the above structure, the two first inner support components 22 can be moved away from each other by the first wedge block to expand the corresponding inner sidewall of the power bank shell 6. The second actuator 25 is a second wedge block with a third inclined surface 251 on each of its opposite sides. Two second inner support components 23 are symmetrically arranged on both sides of the second wedge block with the third inclined surface 251. Each of the two second inner support components 23 has a fourth inclined surface 2321 that slides in contact with the third inclined surface 251. The slope direction of each second inclined surface 2221 is opposite to that of the corresponding fourth inclined surface 2321. With the above structure, the two second inner support components 23 can be actuated by the second wedge block to move away from each other and expand the corresponding inner sidewall of the power bank shell 6.

[0022] Compared with the prior art, the fixture for processing the power bank casing in this embodiment of the utility model uses a drive mechanism 27 to drive a sliding shaft 26 to move axially upward. The sliding shaft 26 drives the first wedge block and the second wedge block to move upward. The upward-moving first wedge block, under the sliding cooperation of the first inclined surface 241 and the second inclined surface 2221, actuates the two first inner support components 22 to move away from each other to expand the corresponding inner sidewalls of the power bank casing 6. At the same time, the upward-moving second wedge block, under the sliding cooperation of the third inclined surface 251 and the fourth inclined surface 2321, actuates the two second inner support components 23 to move away from each other to expand the corresponding inner sidewalls of the power bank casing 6. In this way, the two outwardly expanding first inner support components 22 and the two outwardly expanding second inner support components 23 can uniformly and stably support the inner sidewalls of the power bank casing 6 from the inside, which can maintain the stability of the clamping and positioning of the power bank casing 6, avoid deformation of the power bank casing 6, and effectively prevent damage to the outer surface of the power bank casing 6.

[0023] Please refer to the following: Figure 1 , Figure 3 , Figure 6 and Figure 8In some embodiments, the first inner support assembly 22 includes a first inner support block 221 for supporting the outer wall of the power bank casing 6 from the inside out, a first rectangular sliding block 222 capable of driving the first inner support block 221 to slide in the left and right direction, and a first guide post 223 for guiding the first inner support block 221 to slide in the left and right direction. The clamp base 21 is provided with a first guide sliding hole 211 that slidably engages with the first guide post 223. The first end of the first guide post 223 is connected to the first inner support block 221, and the second end of the first guide post 223 is slidably inserted into the first guide sliding hole 211. The clamp base 21 is also provided with a first sliding groove 212 that engages with the first rectangular sliding block 222. The first rectangular sliding block 222 is slidably installed in the first sliding groove 212. The first end of the first rectangular sliding block 222 located outside the clamp base 21 is fixedly connected to the first inner support block 221, and the second end of the first rectangular sliding block 222 located inside the clamp base 21 is provided with a second inclined surface 2221. The fixture seat 21 is provided with a central hole 213 that communicates with two first sliding grooves 212. The axis of the central hole 213 is parallel to the axis of the sliding shaft 26. The sliding shaft 26 passes through the central hole 213. The first wedge block is located in the central hole 213, and the first inclined surface 241 on the first wedge block slides in contact with the second inclined surface 2221 on the first rectangular sliding block 222. In this embodiment, the sliding connection between the first rectangular sliding block 222 and the first sliding groove 212 allows the first inner support block 221 to slide in the left-right direction. The sliding shaft 26 is driven axially upward by the driving mechanism 27, causing the first wedge block to move upward. The upward-moving wedge block, through the sliding engagement between the first inclined surface 241 on the first wedge block and the second inclined surface 2221 on the first rectangular sliding block 222, actuates the two first rectangular sliding blocks 222, causing the two first inner support blocks 221 to move away from each other. This allows the two first inner support blocks 221 to expand and support the corresponding inner walls of the power bank casing 6, achieving the purpose of clamping the power bank casing 6 from within. Furthermore, the sliding engagement between the first guide post 223 and the first guide sliding hole 211 guides the movement of the two first inner support blocks 221, improving the stability and reliability of their left-right movement. It should be noted that there can be multiple first guide posts 223, and multiple first guide sliding holes 211 are provided on the fixture seat 21.

[0024] Please refer to the following: Figure 1 , Figure 2 and Figure 4In some embodiments, the first inner support assembly 22 further includes a first elastic support block 224 for elastically supporting the inner wall of the power bank casing 6, the first elastic support block 224 being fixedly mounted on the first inner support block 221. In this embodiment, by providing the first elastic support block 224 on the first inner support block 221, the first elastic support block 224 provides elastic support to the inner wall of the power bank casing 6. This increases the friction between the first elastic support block 224 and the inner wall of the power bank casing 6, and also provides flexible support to the inner wall of the power bank casing 6, preventing damage to the power bank casing 6. It should be noted that the first elastic support block 224 may be, but is not limited to, an elastic element made of rubber or silicone.

[0025] Please refer to the following: Figure 3 , Figure 6 and Figure 8 In some embodiments, the first inner support block 221 is provided with a first positioning groove 2211 for accommodating and positioning the first elastic support block 224, and the first elastic support block 224 is fixedly disposed in the first positioning groove 2211.

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 5 and Figure 8In some embodiments, the second inner support assembly 23 includes a second inner support block 231 for supporting the outer wall of the power bank casing 6 from the inside out, a second rectangular sliding block 232 capable of driving the second inner support block 231 to slide in the left and right direction, and a second guide post 233 for guiding the second inner support block 231 to slide in the left and right direction. The clamping base 21 is provided with a second guide sliding hole 214 that slidably engages with the second guide post 233. The first end of the second guide post 233 is connected to the second inner support block 231, and the second end of the second guide post 233 is slidably inserted into the second guide sliding hole 214. The clamping base 21 is also provided with a second rectangular sliding block 232 that engages with the second rectangular sliding block 232. The second sliding groove 215 is fitted together, and the second rectangular sliding block 232 is slidably installed in the second sliding groove 215. The first end of the second rectangular sliding block 232 located outside the clamp seat 21 is fixedly connected to the second inner support block 231. The second end of the second rectangular sliding block 232 located inside the clamp seat 21 is provided with a fourth inclined surface 2321. The clamp seat 21 is provided with a central hole 213 communicating with the two second sliding grooves 215. The axis of the central hole 213 is parallel to the axis of the sliding shaft 26. The sliding shaft 26 passes through the central hole 213. The second wedge block is located in the central hole 213, and the third inclined surface 251 on the second wedge block slides in contact with the fourth inclined surface 2321 on the second rectangular sliding block 232. In this embodiment, the sliding connection between the second rectangular sliding block 232 and the second sliding groove 215 allows the second inner support block 231 to slide in the left-right direction. The sliding shaft 26 is driven axially upward by the driving mechanism 27, causing the second wedge block to move upward. The upward-moving second wedge block, through the sliding engagement between the third inclined surface 251 on the second wedge block and the fourth inclined surface 2321 on the second rectangular sliding block 232, actuates the two second rectangular sliding blocks 232, causing the two second inner support blocks 231 to move away from each other. This allows the two second inner support blocks 231 to expand and support the corresponding inner walls of the power bank casing 6, achieving the purpose of clamping the power bank casing 6 from within. Furthermore, the sliding engagement between the second guide post 233 and the second guide sliding hole 214 guides the movement of the two second inner support blocks 231, improving the stability and reliability of their left-right movement. It should be noted that multiple second guide posts 233 can be provided, and multiple second guide sliding holes 214 are provided on the fixture seat 21 accordingly.

The second elastic support block 234 is fixedly disposed on the second inner support block 231. In this embodiment, by providing the second elastic support block 234 on the second inner support block 231, the inner wall of the power bank casing 6 is elastically supported by the second elastic support block 234. On the one hand, this increases the friction between the second elastic support block 234 and the inner wall of the power bank casing 6. On the other hand, it provides flexible support to the inner wall of the power bank casing 6, preventing damage to the power bank casing 6. It should be noted that the second elastic support block 234 may be, but is not limited to, an elastic element made of rubber or silicone.
