Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a speed measurement and lighting device, including: a device ring 1; an outer wall of the device ring 1 is provided with a placement groove 2, a PCB component board 3 is clamped in the placement groove 2, an outer wall of the PCB component board 3 is respectively provided with a pair of LED lamp beads 4 and two symmetric Hall sensors 5, the outer wall of the device ring 1 is sequentially provided with a plurality of connection holes 8, and fastening screws 9 are inserted into the connection holes 8;

[0024] The device ring 1 is a relatively convenient detachable device, which is fixedly installed through the fastening screw 9 of the connection hole 8 and the magnetic drill press. The PCB component board 3 in its placement groove 2 adopts the structure of double LED lamp beads 4 and double Hall sensors 5. The LED lamp beads 4 are used for lighting, and the Hall sensors 5 are used to sense and feedback the spindle speed of the magnetic drill press. It can still perform the functions of lighting and testing when a single lamp or a single Hall fails, making it more reliable to use.

[0025] Preferably, one end of the PCB component board 3 is fixed with a lead wire 6, and one end of the lead wire 6 is fixed with a plug;

[0027] Preferably, a cover plate 7 for blocking the placement groove 2 is clamped on the outer wall of the device ring 1, and a lighting hole is opened on the outer wall of the cover plate 7;

[0028] The placement ring daily blocks the placement groove 2 through the cover plate 7 to protect the internal components of the placement groove 2, and ensures the normal output of the lighting source through the opened lighting hole.

[0029] Preferably, the irradiation end of the LED lamp bead 4 extends into the lighting hole of the cover plate 7;

[0030] The extended setting of the LED lamp bead 4 facilitates the light emitted by it to irradiate the part during the operation of the spindle tool through the cover plate 7.

[0031] Preferably, a plurality of positioning pins 10 are sequentially fixed on the outer wall of the device ring 1;

[0032] By inserting the positioning pin 10 into the reduction gearbox, the device ring 1 can be quickly positioned on the reduction gearbox for screwing the fastening screw 9.

The inner ring surface of the device ring 1 is concentric with the spindle. Then, the lead wire 6 of its PCB component board 3 is connected to the machine body and connected to the whole machine controller of the magnetic drill press;

The whole machine controller supplies power to the LED lamp beads 4 on the PCB component board 3, and the LED lamp beads 4 light up to illuminate the tool head area of the spindle. When the spindle rotates forward and backward, the Hall sensor 5 on the PCB component board 3 senses the magnetic field of the magnetic beads on the spindle and sends the signal to the whole machine controller. The whole machine controller sends the rotation speed signal to the instrument display, and the operator can adjust the rotation speed plus and minus buttons according to the display to obtain the rotation speed matching the diameter of the spindle tool.
