The anodized layer can significantly improve the wear resistance, corrosion resistance, and aesthetics of the housing. However, its impact resistance directly determines the protective effect of the power tool in scenarios such as accidental drops and collisions. If the anodized layer peels off or cracks under impact, it will not only affect the appearance and service life of the housing, but may also damage internal components and cause safety hazards.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: As Figures 1-8 As shown, the present invention provides a technical solution: a device for testing the impact resistance of anodized layers of power tool housings, including a testing box 1, an impact testing mechanism 2 is provided on the top inner side of the testing box 1, and a positioning mechanism 3 is provided on the bottom inner side of the testing box 1.

A connecting frame 208 is fixedly connected to the bottom of the iron plate 207, and a lifting sliding frame 209 is fixedly installed at the bottom of the connecting frame 208. An impact head 210 is provided at the bottom of the lifting sliding frame 209. The top of the lifting sliding frame 209 is symmetrically fixedly connected with guide mounting tubes 214. Multiple counterweights 215 are provided on the top of the lifting sliding frame 209. The guide mounting tubes 214 all pass through the inner side of the counterweights 215. The top of the guide mounting tubes 214 is threadedly connected with fastening screws 216. A spring compression member 217 is connected to the outside of the fastening screws 216. The spring compression member 217 is sleeved on the outside of the guide mounting tubes 214. The bottom of the spring compression member 217 abuts against the top of one of the counterweights 215.

[0022] In this embodiment, the housing 101 provides operating space and installation location, which facilitates efficient and safe impact resistance testing. The take-up roller 202, in conjunction with the top cover 201, is installed on the top of the housing 101, providing installation space for the take-up roller 202. Simultaneously, the first motor 203 drives the hoisting rope 204 for winding or releasing. The hoisting rope 204 is connected to the controllable electromagnetic block 206, facilitating lifting and lowering adjustment. The controllable electromagnetic block 206 is electromagnetically controlled and can be magnetically connected to the iron plate 207. The strength of the magnetic force can be adjusted according to usage, facilitating rapid adsorption and release operations. The connecting frame 208 is fixed to the bottom of the iron plate 207, facilitating further connection to the lifting sliding frame 209. An impact head 210 is provided at the bottom of the lifting sliding frame 209. This allows the impact head 210 to fall freely and impact the power tool housing when the controllable electromagnetic block 206 is released from the iron plate 207, enabling rapid and efficient testing of the impact resistance of the anodized layer. During the testing process, the top of the lifting sliding frame 209 can be fitted with different numbers of counterweights 215 according to the required testing force to change the impact force, thereby altering the testing parameters. This allows for adjustments to suit different needs, effectively expanding the testing range and ensuring testing efficiency and versatility. The guide mounting tube 214 provides guidance when stacking the counterweights 215. The fastening screws 216 are threaded onto the guide mounting tube 214, facilitating the pressing of the spring compression component 217 onto the surface of the counterweights 215. This provides effective limiting, ensuring stability during use and preventing excessive impact force from damaging the guide mounting tube 214, thus avoiding difficulties in disassembly and replacement later.

[0023] Example 2: As Figure 1 , Figure 7 and Figure 8As shown, the positioning mechanism 3 includes a base plate 301. Hydraulic cylinders 302 are mounted at both ends of the top of the base plate 301. A connecting guide rail 303 is connected to the output end of each hydraulic cylinder 302. A second motor 309 is mounted at one end of the connecting guide rail 303. A bidirectional adjusting screw 310 is connected to the output end of the second motor 309. A right-angle clamping member 311 is symmetrically threaded onto the outer wall of the bidirectional adjusting screw 310. A pneumatic lifting column 313 is mounted on the top of the right-angle clamping member 311. A right-angle slider 315 is mounted on the top of the pneumatic lifting column 313. A pressure plate 316 is fixedly connected to the inner side of the right-angle slider 315. Guide crossbars 304 are symmetrically fixedly connected to one side of the connecting guide rail 303. The two ends of the hydraulic cylinders 302... A guide member 305 is fixedly connected to the side, and a guide crossbar 304 is movably passed through the inner side of the guide member 305. An oil supply pipe 306 is fixedly connected to one side of the hydraulic cylinder 302. A hydraulic oil reservoir 308 is fixedly installed on the side of the base plate 301. A hydraulic oil pump 307 is set on the top of the hydraulic oil reservoir 308. One end of each of the two oil supply pipes 306 is fixedly connected to both ends of the hydraulic oil pump 307. Several first anti-slip strips 312 are evenly distributed on the inner side of the right-angle clamp 311. Vertical guide plates 314 are symmetrically fixedly connected to the top of the right-angle clamp 311. The vertical guide plates 314 are all movably passed through the inner side of the right-angle slider 315. Several second anti-slip strips 317 are evenly distributed on the bottom of the pressure plate 316.

[0024] In this embodiment, hydraulic cylinders 302 are symmetrically mounted on the top of the base plate 301, and the output end of the hydraulic cylinders 302 is connected to the connecting guide rails 303. This facilitates the control of the two connecting guide rails 303 moving towards each other, achieving the function of opposing clamping. Simultaneously, guide crossbars 304 are symmetrically arranged on the outer side of the connecting guide rails 303, and are connected through guide members 305 on the outer side of the hydraulic cylinders 302, providing effective guidance and improving stability during use. The hydraulic cylinders 302 are connected to the hydraulic pump 307 via the oil supply pipe 306, and the hydraulic pump 307 is connected to the hydraulic oil reservoir 308. This allows hydraulic oil to be drawn from the hydraulic oil reservoir 308 and then transported through the oil supply pipe 306 to the interior of the hydraulic cylinders 302 for hydraulic extension and retraction, facilitating the positioning and clamping function. A right-angle clamping member 311 is located inside the connecting guide rail 303 and works in conjunction with a second motor 309 to drive a bidirectional adjusting screw 310 to rotate, facilitating the adjustment of the position of the right-angle clamping member 311 and achieving a centered positioning effect for both longitudinal and transverse clamping, thus ensuring the accuracy of the impact. A right-angle slider 315 is connected to the top of the right-angle clamping member 311 via a pneumatic lifting column 313. A pressure plate 316 is provided inside the right-angle slider 315. The pneumatic lifting column 313 controls the lifting height adjustment of the right-angle slider 315, thereby providing a certain clamping effect at the top. A vertical guide plate 314 provides guidance to help the right-angle slider 315 maintain stability during lifting. The first anti-slip strip 312 symmetrically arranged inside the right-angle clamping member 311 and the second anti-slip strip 317 distributed at the bottom of the pressure plate 316 both provide anti-slip effects, further improving stability.

[0025] Example 3: As Figures 1-6 As shown, a guide sleeve 205 is provided on the inner side of the top of the outer shell 101. The hoisting rope 204 passes through the inner side of the guide sleeve 205. A top cover 201 is provided on the outer side of the take-up roller 202. The top cover 201 is fixedly installed on the top of the outer shell 101. The two ends of the lifting sliding frame 209 are movably connected to the lifting guide rails 211. The inner side of the lifting guide rails 211 is symmetrically fixedly connected to the lifting guide rods 212. The lifting guide rods 212 all movably pass through the two ends of the lifting sliding frame 209. Limit strips 213 are provided on the four sides of the top of the lifting sliding frame 209. The limit strips 213 are located on the outer side of one of the counterweights 215. The front of the outer shell 101 is provided with an upper door 102 and a side door 103. The side door 103 is located below the upper door 102. A controller 104 is provided on one side of the outer shell 101.

[0026] In this embodiment, the guide sleeve 205 serves as a dedicated guide component for the lifting rope 204, precisely constraining the winding and unwinding trajectory of the lifting rope 204. This effectively prevents the lifting rope 204 from shifting, tangling, or wearing during the lifting and lowering of the counterweight 215, ensuring that the lifting rope 204 always runs smoothly along the preset path, providing a fundamental guarantee for the accuracy of the impact test. The top cover 201, through its rigid connection with the main frame of the equipment, provides a closed and stable mounting cavity for the winding roller 202. This not only protects the winding roller 202 and its transmission components from external dust and debris intrusion that could affect transmission stability, but also prevents the winding roller 202 from axial movement or radial displacement during high-speed winding and unwinding through structural limiting, further ensuring the operational reliability of the winding roller 202. The lifting guide rails 211 are symmetrically connected to both ends of the lifting sliding frame 209 and are adapted to the end sliding structure of the lifting sliding frame 209. Simultaneously, the lifting guide rod 212 passes through a pre-drilled hole in the lifting sliding frame 209 along the height direction of the equipment, forming a dual guide structure of rails and rods. This dual guide design can precisely constrain the lifting movement of the lifting sliding frame 209 in both horizontal and vertical dimensions, effectively offsetting the lateral impact force generated by the falling counterweight 215 during the impact test, preventing the lifting sliding frame 209 from tilting, swaying, or jamming, and significantly improving the stability of the equipment operation and the repeatability of test data during the impact test. The limiting strip 213 is fixedly installed along the side of the counterweight 215, and its inner sidewall forms a clearance fit with the outer sidewall of the counterweight 215. This allows for precise positioning of the counterweight 215, preventing it from shifting left or right or moving forward or backward on the lifting sliding frame 209. At the same time, the limiting strip 213 can also offset part of the lateral impact force during the moment the counterweight 215 falls and impacts, preventing the counterweight 215 from tilting due to uneven force distribution. This further improves the structural stability of the counterweight 215 after installation and the accuracy of the impact test. Both the top-opening door 102 and the side-opening door 103 are located on the front of the main body of the equipment and adopt an openable hinged structure design, providing convenient opening and closing functions. During equipment debugging, sample clamping, or internal component maintenance, operators can quickly access the internal structure of the equipment by opening either the top-opening door 102 or the side-opening door 103, significantly improving operational convenience. During impact testing, the top-opening door 102 and the side-opening door 103, when closed, form a sealed cavity with the main body of the equipment, effectively blocking any debris that may splash during the impact and preventing accidental contact with moving parts by the operator, providing reliable safety protection for impact testing. The controller 104 is integrated into the front operating area of ​​the main body of the equipment. It establishes signal connections with the drive components, sensor components, and actuators inside the equipment via wired or wireless means, and has multiple integrated functions such as parameter setting, start control, emergency stop, and data display.Operators can easily set key parameters such as impact height, counterweight mass, and number of tests through the controller 104, and monitor the equipment's operating status and test data in real time without having to manually intervene in the internal structure of the equipment. This significantly reduces the difficulty of operation and improves the convenience and intelligence of equipment operation.

[0027] In this invention, the impact resistance testing equipment for the anodized layer of an electric tool housing is first used by symmetrically mounting hydraulic cylinders 302 on the top of the base plate 301. The output end of the hydraulic cylinders 302 is connected to the connecting guide rails 303, facilitating the control of the opposing movement between the two connecting guide rails 303 and achieving the function of opposing clamping. Simultaneously, guide crossbars 304 symmetrically arranged on the outer side of the connecting guide rails 303 are connected through guide members 305 arranged on the outer side of the hydraulic cylinders 302, providing effective guidance and improving stability during use. The hydraulic cylinders 302 are connected to the hydraulic pump 307 via an oil supply pipe 306, and the hydraulic pump 307 is connected to the hydraulic oil reservoir 308, facilitating the extraction of hydraulic oil from the reservoir 308 and its delivery via the oil supply pipe 306 to the hydraulic cylinders 302 for hydraulic extension and retraction, thus achieving the positioning and clamping function. A right-angle clamping member 311 is located inside the connecting guide rail 303 and works in conjunction with a second motor 309 to drive a bidirectional adjusting screw 310 to rotate, facilitating the adjustment of the position of the right-angle clamping member 311 and achieving a centered positioning effect for both longitudinal and transverse clamping, thus ensuring the accuracy of the impact. A right-angle slider 315 is connected to the top of the right-angle clamping member 311 via a pneumatic lifting column 313. A pressure plate 316 is provided inside the right-angle slider 315. The pneumatic lifting column 313 controls the lifting height adjustment of the right-angle slider 315, thereby providing a certain clamping effect at the top. A vertical guide plate 314 provides guidance to help the right-angle slider 315 maintain stability during lifting. A first anti-slip strip 312 is symmetrically arranged on the inner side of the right-angle clamping member 311, and a second anti-slip strip 317 is distributed at the bottom of the pressure plate 316, both providing anti-slip properties.

[0028] The take-up roller 202, in conjunction with the top cover 201, is installed on the top of the housing 101, providing installation space for the take-up roller 202. Simultaneously, the first motor 203 drives the hoisting rope 204 for winding or releasing. The hoisting rope 204 is connected to the controllable electromagnetic block 206, facilitating lifting and lowering adjustment. The controllable electromagnetic block 206 is electromagnetically controlled and can be magnetically connected to the iron plate 207. The strength of the magnetic force can be adjusted according to usage, facilitating rapid adsorption and release operations. The connecting frame 208 is fixed to the bottom of the iron plate 207, facilitating further connection to the lifting sliding frame 209. An impact head 210 is provided at the bottom of the lifting sliding frame 209. This allows the impact head 210 to fall freely and impact the power tool housing when the controllable electromagnetic block 206 is released from the iron plate 207, enabling rapid and efficient testing of the impact resistance of the anodized layer. During testing, the top of the lifting sliding frame 209 can be fitted with different numbers of counterweights 215 according to the required testing force to change the impact force, thereby altering the test parameters. This allows for adjustments to suit different needs, effectively expanding the testing range and ensuring testing efficiency and versatility. The guide mounting tube 214 provides guidance during the stacking of counterweights 215. The fastening screws 216 are threaded onto the guide mounting tube 214, facilitating the pressing of the spring clamp 217 onto the surface of the counterweights 215, providing effective limiting and ensuring stability during use. This also prevents excessive impact force from damaging the guide mounting tube 214. The guide sleeve 205 guides the lifting rope 204, while the top cover 201 ensures the stable installation of the take-up roller 202. The lifting guide rail 211 connects to both ends of the lifting sliding frame 209, and the lifting guide rod 212 runs through it, providing lifting guidance and ensuring stability during the impact test. The limiting strip 213 provides lateral restraint for the counterweight 215, improving stability after installation. Both the top-opening door 102 and the side-opening door 103 are located on the front, facilitating opening and closing. Opening allows for convenient internal operation, while closing ensures safety during impacts. The controller 104 provides equipment control, enhancing operational convenience.
