Problems solved by technology
[0002] At present, the robot joint reduction devices on the market include high-precision and medium-precision ones. Among them, the high-precision ones have harmonic reducers or RV reducers, which are expensive. The medium and low-precision ones have planetary reducers, which are low in cost but poor in precision. , the gap is large, which will cause the shaking phenomenon when the robot arm moves and stops, reducing the repeated positioning accuracy

The invention discloses a robot joint deceleration device, which includes a first-stage deceleration device and a second-stage deceleration device. The first-stage deceleration device includes a bottom plate, a linear guide rail and a nut connecting block. The first screw rod and the second screw rod are coaxially connected to the On the rod bearing, the diameter of the first screw rod is greater than the diameter of the second screw rod, and the first nut and the first screw rod, and the second nut and the second screw rod cooperate with each other. Beneficial effects of the present invention: the first-stage reduction device and the second-stage reduction device are arranged on the reduction device, and the first-stage reduction device is coaxially connected through screw rods of different sizes, and the screw rods drive matching nuts to connect block, and then achieve different revolutions under the same stroke to achieve the effect of deceleration, and the deceleration effect is outstanding through the cooperation of the first-stage deceleration device and the second-stage deceleration device. In addition, the deceleration device of the present invention has high flexibility, The effect of high precision, in addition, the present invention also has the characteristics of simple operation and low manufacturing cost.
