Precise workbench based on LED light source

Abstract

The invention discloses a precise workbench based on an LED light source in the technical field of precise machinery. The precise workbench comprises an X-direction workbench body. Two sets of same-structure support legs are installed at the front end and the rear end of the bottom of a Y-direction workbench body symmetrically. A Z-direction motor is installed at the top of an L-shaped vertical plate. The outer wall of a Z-direction ball screw is sleeved with a bearing table. A lampholder is arranged at the top of the bearing table, and the LED light source is installed on the lampholder. Theprecise workbench is simple to operate, an X-direction motor, a Y-direction motor and the Z-direction motor are all servo motors, the LED light source can move precisely in three-dimensional space, and the lighting range of the LED light source is widened effectively. The left side and the right side of the bottom of an arc-shaped reflector are provided with an air inlet and an air outlet correspondingly, and thus air mobility of an inner cavity of the arc-shaped reflector is improved. A heat dissipation plate is provided with heat dissipation holes matched with a circuit board, heat generatedduring working of an LED lamp bead and the circuit board can be absorbed and removed conveniently, the two sets of same-structure support legs are installed at the front end and the rear end of the bottom of the Y-direction workbench body symmetrically, and thus the Y-direction workbench body can be supported conveniently.

Description

technical field [0001] The invention relates to the technical field of precision machinery, in particular to a precision workbench based on an LED light source. Background technique [0002] LED light source (Light-Emitting Diode) is a light source with a light-emitting diode (LED) as the illuminant. It has the characteristics of high efficiency and long life. Most of the existing LED light sources are used for lighting purposes. Realize lighting in different positions. [0003] In Chinese Patent No. CN206509993U, a precision workbench based on LED light source is proposed, including a precision workbench body based on LED light source composed of a workbench and an LED light source group. The workbench consists of an X-direction workbench and a Y-direction workbench. The X-direction workbench is vertically set above the Y-direction workbench. The X-direction workbench is composed of a support mechanism and a transmission mechanism. The support mechanism is composed of a ba...

AI Technical Summary

Problems solved by technology

[0004] 1. The range of motion of the LED light source is limited, and the workbench can only achieve precise movement in two-dimensional space, resulting in a narrowing of the lighting range of the LED light source, which is not convenient for the staff to work and affects work efficiency;

[0005] 2. The heat dissipation performance of the LED light source is poor, and it is easy to burn out the light-emitting diode due to excessive temperature after working for a long time, reducing the normal service life of the light-emitting diode;

[0006] 3. The structure of the patent is too simple, the stability is poor, and the practicability is low. Therefore, we propose a precision workbench based on LED light source
