The technical scheme that the utility model is further limited is:

The aforementioned electric telescopic arm device, the sliding sleeve and the telescopic arm have a rectangular structure, and at least two sliding seats arranged in series are arranged on the inner wall of the sliding sleeve, which is arranged in a rectangular structure, which is convenient for installation and maintenance, and is connected in series through two sliding blocks The setting can increase the stability and reliability of the telescopic arm movement, ensure the accuracy of welding, ensure the quality of welding, and increase the service life of the equipment.

In the aforementioned electric telescopic arm device, the geared motor is a worm geared motor, and the worm geared motor has good transmission stability, high safety factor, simple control and high precision.

The aforementioned electric telescopic arm device is provided with a limit block at the end of the T-shaped screw rod away from the deceleration motor. The limit block is threadedly connected with the T-shaped screw rod, and the limit block can prevent the telescopic arm from exceeding the stroke and slipping during the moving process. cause production accidents.

The beneficial effects of the utility model are: by setting a linear slide rail on the telescopic arm, and setting a slider inside the sliding sleeve, the T-shaped screw rod is driven by a deceleration motor, so that the telescopic arm moves on the slide block, and the linear slide rail is used to move the telescopic arm. The cooperation with the linear slider increases the precision of the telescopic arm movement, improves the welding quality of the equipment at work, reduces the scrap rate and repair problems, and has a simple structure, convenient processing and maintenance, simple operation, high work efficiency and long service life; It is set in a rectangular structure, which is convenient for installation and maintenance, and the stability and reliability of the telescopic arm movement can be increased by setting two sliders in series, ensuring the accuracy of welding, ensuring the quality of welding, and increasing the service life of the equipment; through the limit block It can prevent the telescopic arm from exceeding the stroke during the moving process, and prevent production accidents caused by slipping.
