[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a grinding device for parts processing, comprising a base 1, a motor 2 is fixedly mounted on the upper surface of the base 1, a rotating wheel 3 is fixedly mounted on the output end of the motor 2, sandpaper 4 is glued to the side wall of the rotating wheel 3, a fixed block 6 is fixedly connected to the upper surface of the base 1, two guide rails 7 are fixedly connected to the surface of the fixed block 6, a telescopic plate 5 is slidably connected to the side walls of the two guide rails 7, a screw rod 10 is internally threadedly connected to the telescopic plate 5, the screw rod 10 is internally rotatably connected to the fixed block 6, an adjustment structure 8 is provided on the upper surface of the telescopic plate 5, and a cleaning structure 9 is provided on the surface of the motor 2.

[0030] The specific settings and functions of the adjustment structure 8 and the cleaning structure 9 are described in detail below.

[0031] Reference Figure 1-Figure 3As shown, in this embodiment: the adjustment structure 8 includes a support frame 801 fixedly connected to the upper end of the telescopic plate 5, and two sliders 803 are slidably connected to the inner wall of the support frame 801. The upper ends of the two sliders 803 are fixedly installed with a limit bar 804. The side wall of the limit bar 804 is provided with a reserved groove 811 with a "V"-shaped cross section. The internal thread of the support frame 801 is connected with a screw rod 802, and the screw rod 802 and the limit bar 804 are internally rotatably connected. The staff can clamp the parts inside the two limit bars 804 with a "V"-shaped cross section to prevent the cylindrical parts from shaking up and down during the clamping process. The screw rod 802 is rotated, and the screw rod 802 will push the limit bar 804 to move, so as to realize the clamping work of the cylindrical structure parts, thereby improving the stability of the cylindrical structure parts in the later clamping process. The inner part of the limit bar 804 is slidably connected to a slide bar 805, and the inner part of the slide bar 805 is slidably connected to a slide bar 806. A filling bar 809 with a triangular cross-section is fixedly installed on the end surface of the slide bar 806. The slide bar 806 is pulled to lift the filling bar 809, and the slide bar 805 inside the limit bar 804 is slid to move the filling bar 809 to a position corresponding to the reserved groove 811, so that the reserved groove 811 can be filled.

[0032] The end surface of the slide bar 806 is fixedly mounted with a stopper 807, and the surface of the slide bar 806 is covered with a first spring 808, and the two ends of the first spring 808 are fixedly connected to the stopper 807 and the slide bar 805, respectively. The slide bar 806 is sleeved into the inner side of the reserved groove 811 by the elastic force of the first spring 808 between the stopper 807 and the slide bar 805. The side wall of the filling bar 809 is fixedly connected with two auxiliary blocks 810, and the auxiliary blocks 810 are "V"-shaped structures. By setting the auxiliary blocks 810 on both sides of the filling bar 809, the shaking of the filling bar 809 after being filled in the inner side of the reserved groove 811 is avoided.

[0033] Reference Figure 1-Figure 2 and Figure 4 As shown, specifically, the cleaning structure 9 includes a connecting strip 91 fixedly mounted on the surface of the motor 2, a draw strip 92 is slidably connected inside the connecting strip 91, a brush plate 93 is fixedly mounted on the end surface of the draw strip 92, and a plurality of steel bristles 96 are evenly and fixedly connected on the surface of the brush plate 93. When the steel bristles 96 on the brush plate 93 are attached to the surface of the sandpaper 4, the steel bristles 96 arranged in the arc surface structure improve the tightness of the attachment to the sandpaper 4, and the steel bristles 96 can realize the cleaning work of the powder stuck inside the sandpaper 4.

[0034] A groove block 94 is fixedly installed at one end of the draw bar 92, and the cleaning surface on which a plurality of steel bristles 96 are arranged is an arc surface. The arrangement of the groove block 94 facilitates the hand to push the draw bar 92. Two second springs 95 are fixedly installed between the brush plate 93 and the connecting bar 91. When the groove block 94 is released, the brush plate 93 is lifted by the pulling force of the second spring 95, thereby avoiding the situation where the steel bristles 96 are attached to the surface of the sandpaper 4 for a long time and are worn out.

[0035] Working principle: when it is necessary to clamp and process the cylindrical structural parts, the staff can clamp the parts on the inner sides of the two limit bars 804 with a "V"-shaped cross-section for clamping, which can prevent the cylindrical parts from shaking up and down during the clamping process. By rotating the screw 802, the screw 802 will push the limit bar 804 to move, so as to realize the clamping of the cylindrical structural parts, thereby improving the stability of the cylindrical structural parts in the later clamping process. At this time, the screw 10 can be rotated to realize the movement of the telescopic plate 5 and the support frame 801, which is convenient for pushing the parts during the grinding process. The setting of the telescopic plate 5 can be adjusted for the grinding processing of parts of different heights. When it is necessary to clamp the rectangular structural parts before grinding, pull the sliding bar 806 to lift the filling bar 809, slide the sliding bar 805 on the inner side of the limit bar 804, and move the filling bar 809 to the position aligned with the reserved groove 811. The corresponding position is released, and the moving bar is released. At this time, the sliding bar 806 is inserted into the inner side of the reserved groove 811 by the elastic force of the first spring 808 between the stop block 807 and the sliding bar 805, so that the filling of the reserved groove 811 can be realized, and the flatness of the relative position of the two limit bars 804 during use is improved, thereby facilitating the stable structural processing of the planar structural parts. By setting the auxiliary blocks 810 on both sides of the filling bar 809, the shaking of the filling bar 809 after filling the inner side of the reserved groove 811 is avoided, and the stability of the filling bar 809 when filling the inner side of the reserved groove 811 is improved. By setting the adjustment structure 8 and adjusting the structure of the opposite surfaces of the two limit bars 804, the stable clamping of different structural parts such as cylinders or rectangles is facilitated, thereby improving the stability during the grinding of parts with different shapes of structures, and to a certain extent improving the performance of the grinding device.

[0036] When powder is stuck on the inner side of the sandpaper 4, the motor 2 is started and the staff can press the groove block 94. The setting of the groove block 94 facilitates the hand to push the draw bar 92. When the steel bristles 96 on the brush plate 93 are in contact with the surface of the sandpaper 4, the steel bristles 96 arranged in the arc structure improve the tightness of the contact with the sandpaper 4. The steel bristles 96 can clean the powder stuck on the inner side of the sandpaper 4, thereby improving the performance of the sandpaper 4. The groove block 94 is released, and the brush plate 93 is lifted up by the pulling force of the second spring 95, thereby avoiding the situation where the steel bristles 96 are long-term in contact with the surface of the sandpaper 4 and are damaged. By setting the cleaning structure 9, the regular cleaning of the sandpaper 4 on the rotating wheel 3 is facilitated, and the performance of the grinding device is further improved.
