Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The embodiment of the present application solves the problem that the current oil pump nozzles are mainly cleaned by clamping them with a clamping ring on a cleaning device, and the clamping ring can usually only clamp one group of oil pump nozzles for cleaning, resulting in low overall cleaning efficiency of the oil pump nozzles.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a grinding and cleaning device for processing a fuel injection pump nozzle.

[0027] According to the attached Figure 1-6 As shown, the grinding and cleaning device for processing the fuel injection pump nozzle includes a cleaning box 1, and a storage assembly 2 is arranged inside the cleaning box 1. The storage assembly 2 includes a bottom frame 201, a top frame 202, a support rod 203 and an electric telescopic rod 205;

[0028] The top frame 202 is rotatably connected to the top of the bottom frame 201, the support rod 203 is fixedly connected to the top of the bottom frame 201, the electric telescopic rod 205 is fixedly connected to the top of the support rod 203, and the end of the electric telescopic rod 205 is fixedly connected to the inner wall of the cleaning box 1. By arranging the bottom frame 201 and the top frame 202 on the cleaning box 1, multiple groups of fuel injection pump nozzles can be clamped and placed at the same time, thereby improving the efficiency of cleaning the fuel injection pump nozzles.

[0029] The bottom of the bottom frame 201 is fixedly connected with a hard net 2011, and the top of the top frame 202 is fixedly connected with a flexible net 2021. The hard net 2011 and the flexible net 2021 are in corresponding positions, and the injection pump nozzle can be clamped and cleaned by the meshed hard net 2011 and the flexible net 2021.

[0030] The storage assembly 2 further includes a connecting member 204 and a clamping member 206 . The connecting member 204 is fixedly connected to the bottom of the bottom frame 201 , and the clamping member 206 is rotatably connected to the top of the bottom frame 201 .

[0031] The support rod 203 is placed inside the connecting member 204 , and a fixing plate 2041 is rotatably connected to the top of the connecting member 204 .

[0032] The fixed plate 2041 and the side wall of the bottom frame 201 are fixedly connected with a magnetic plate 2042. The fixed plate 2041 is magnetically fixed to the side wall of the bottom frame 201 through the magnetic plate 2042. By placing the support rods 203 on another group of bottom frames 201 in the connecting piece 204 and rotating the fixed plate 2041 upward so that it is magnetically fixed to the magnetic plate 2042 on the side wall of the bottom frame 201, the number of fuel injection pump nozzles that can be cleaned simultaneously can be increased through multiple groups of storage components 2.
