detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The utility model is a flexible grinding machine for natural jujube stone beads, as shown in Figure 1, including a bottom cover 2, the upper surface of the bottom cover 2 is equipped with a cylinder 23 through a hexagon socket head screw b3, and the upper end of the cylinder 23 passes through a hexagon socket cylinder The head screw b3 is equipped with a cover 11; the middle part of the upper surface of the bottom cover 2 is equipped with a motor mounting seat 21 through the M5 socket head cap screw a1, and a motor 22 is installed in the motor mounting seat 21; two pairs of bearings are installed outside the motor mounting seat 21 6. A spacer 5 is sleeved on the outside of the motor mounting seat 21 between the two pairs of bearings 6; the two pairs of bearings 6 are fitted with a bearing seat 20, and the upper pair of bearings 6 are connected to the motor through the elastic retaining ring 19 for the shaft. The mounting seat 21 is fixed, and the following pair of bearings 6 are fixed with the bearing seat 20 by the circlip 4 through the hole. A turntable 7 is connected to the bearing seat 20, and a support rod 14 is fixed vertically at the center of the upper surface of the turntable 7. A bead support frame 16 is installed on the support rod 14, and the middle part of the bead support frame 16 passes through a spring washer 12 and a hex nut 13. Connected to the upper end of the support rod 14; the bead installation shaft 17 for installing the beads 18 is arranged between the support frame 16 and the rotating disk 7, and the inner bottom surface of the cover 11 is located next to the bead installation shaft 17. A brush clip mounting seat 10 is installed, and the brush clip is installed A brush clip 8 is installed on the seat 10, and a brush 9 for grinding beads 18 is installed on the side of the brush clip 8 facing the bead installation shaft 17, and the brush 9 adopts copper wire to make. The motor 22 is a DC geared motor. A handle 15 is installed in the middle part of the cover 11 .

As shown in Fig. 2 and Fig. 3, the turntable 7 and the bearing seat 20 are connected by hexagon socket head screws, and the bearing seat 20 is connected with the circlip 4 for the hole, the spacer 5, the bearing 6 and the circlip 19 for the shaft. The shaft is fixed outside the motor mounting base 21; at the same time, the DC geared motor 22 is fixed on the motor mounting base 21 by screws; the frequency-variable DC geared motor 22 drives the bearing housing 20 to rotate through the flat hole 26 on the bearing housing 20, Thereby drive rotating disk 7 to rotate. The spindle speed of the DC geared motor 22 is steplessly adjustable from 0 to 400 rpm. As shown in Figure 4, the brush 9 is mounted on the brush clip 8 and screwed to the top; the brush clip 8 is mounted on the brush clip mount 10 through a hexagon socket head screw; the brush clip mount 10 is on the inner bottom surface of the cover 11 A plurality of staggered installations, a plurality of positioning slots 25 are arranged on the inner bottom surface of the cover 11, a U-shaped hole 24 is opened on the brush clip mounting seat 10, and the brush clip mounting seat 10 is installed in the positioning position by the screw connected in the U-shaped hole 24. In the card slot 25. The brush clip mount 10 can move back and forth through the U-shaped hole 24 to control the radial distance between the brushes, and control the radial movement of the brush clip mount 10 on the cover 11 through the positioning slot 25; The mouth is positioned and installed on the cylinder 23. Since the brush 9 is subjected to torque during grinding, two socket head cap screws b3 are installed on the cover 11 to fix it with the cylinder 23 to prevent the cover 11 from rotating and bouncing up and down during grinding. . The handle 15 is convenient for opening the cover 11 during maintenance.

When the beads 18 rotate with the turntable 7, due to the axial force of the brush 9 on the bead installation shaft 17, they can shake slightly in the axial direction, which helps to grind the edges; the installation position of the brush is preferably as shown in Figure 4. The three brushes on the inner ring and the three outer rings are evenly distributed, and the brushes on the inner ring and the outer ring are staggered by a certain angle. The uniform arrangement of the brushes in the inner and outer rings is to enable the beads to be ground over the entire circumference where the edges are present. It is based on the principle of intermittent grinding that the brushes on the inner ring and outer ring are staggered at a certain angle. Intermittent grinding is helpful for grinding and the shedding of debris. Reduce the temperature, so as to avoid burning the original texture of the beads due to excessive temperature.

Grinding, as an important precision and ultra-precision machining method, uses grinding tools and abrasives to grind away a very thin layer of metal from the surface of the workpiece, so that the surface of the workpiece can achieve precise dimensions, accurate geometry and low Surface roughness value. The grinding machine of the utility model discretizes and softens the continuous grinding process, and then it is used for polishing the edges of jujube stone beads. The grinding machine uses a brush made of copper wire as a grinding tool, and finally achieves the purpose of edge polishing through the relative rotation between the fixed brush and the date stone beads. It has good processing performance, stable and reliable processing quality, and advanced processing equipment. The advantages of being simple and easy to operate have effectively improved the efficiency of edge finishing processing of jujube stone beads.
