Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] In the figure, the direct-connected servo motor for resistance spot welding includes a power execution system and a power device, preferably the power device is a motor 1, the motor 1 is connected to the power execution system, and the motor 1 drives the power execution system to move , the specific structure of the power execution system is described below:

[0016] The most important part in the power actuator system is the push rod 2, on which the electrode cap is sleeved for welding. The push rod 2 needs to move back and forth. It is used to accommodate the screw rod 3, the sleeve nut 4 fitted on the screw rod 3, and there is a gap between the screw rod 3 and the shaft hole 1, the screw rod 3 rotates, and the nut 4 can push the push rod 2 Linear reciprocating motion;

[0017] The screw mandrel 3 needs to be driven by a power device, so one end of the scr...

Abstract

The invention relates to a direct connection servo motor for resistance spot welding. The direct connection servo motor comprises a power execution system and a power device. The power device is equipped with the power execution system. The power execution system comprises a push rod. The push rod is internally provided with a shaft hole 1. The shaft hole 1 is internally equipped with a screw rod. One end of the screw rod is connected with the power device. The power device drives the screw rod to move. A gap is formed between the screw rod and the shaft hole 1. The screw rod is sleeved by a matched nut; the nut is fit to the push rod; and when the screw rod rotates, the nut can push the push rod to move back and forth in a straight line. The direct connection servo motor is simple in structure and high in welding precision.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a direct-connected servo motor for a power output device used in robot resistance spot welding equipment Background technique [0002] In the field of resistance welding technology, the parallel connection mode of the motor and the power actuator (also known as the foldback connection) is mainly used. [0003] attached figure 1 It shows the existing switchback servo motor, which is composed of Fanuc robot motor a1 and power actuator. The motor a1 and the ball screw a4 are placed in parallel within a certain distance. The belt pulley a5 and the driving pulley a2 are connected with the timing pulley a5 through the timing belt a3, and the ball screw nut a6 is installed on the motor push rod a7 through screws. The robot controls the rotation of the motor 1 to drive the ball screw a4 through the connection of the pulleys a2, a5 and the synchronous belt a3, and the rotation of the ...
