A drilling transverse beam moving mechanism of a drilling machine

Abstract

The invention discloses a drilling transverse beam moving mechanism of a drilling machine, which comprises two side support plates, and the upper part between the two side support plates is welded and fixed with two transverse beam plates arranged up and down. There is a transverse guide plate between the beams and plates, and the upper and lower parts of the rear wall of the transverse guide plate are formed with horizontal extensions, which are driven by two small-diameter transmission screws while ensuring the same strength as the original single screw. , the two small-diameter transmission screws used are light in weight, thereby reducing the weight of the entire transverse beam mechanism, and at the same time, the low-power main drive servo motor is used to reduce manufacturing costs and energy consumption, and it is passed through the rotation of the main drive servo motor While controlling the moving position of the main moving block driven by the number, by adjusting the position of the two vertical sensing blocks and the sensing of the limit proximity switch, double limit is realized to prevent the rotation speed of the main drive servo motor from being input incorrectly, and it can still work normally. run.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a drilling transverse beam moving mechanism of a drilling machine tool. Background technique [0002] The main machine head at the drill bit or milling cutter of the existing drilling machine or engraving machine generally moves left and right along the transverse beam to realize position adjustment, while the existing transverse beam is generally equipped with a single screw for rotational drive, and The single screw needs to ensure that its strength meets the load-bearing requirements of the main machine head, and the diameter of the screw needs to be large, so that the power of the driving motor needs to be large enough, which increases the weight of the entire transverse beam; [0003] At the same time, the limit of the moving position of the existing main engine head is determined by the rotation speed of the rotating shaft of the driving motor. The driving mo...

Problems solved by technology

[0002] The main machine head at the drill bit or milling cutter of the existing drilling machine or engraving machine generally moves left and right along the transverse beam to realize position adjustment, while the existing transverse beam is generally equipped with a single screw for rotational drive, and The single screw needs to ensure that its strength meets the load-bearing requirements of the main machine head, and the diameter of the screw needs to be large, so that the power of the driving motor needs to be large enough, which increases the weight of the entire transverse beam;

[0003] At the same time, the limit of the moving position of the existing main engine head is determined by the rotation speed of the rotating shaft of the driving motor. The driving motor needs to use a servo motor, and when the number of rotations is controlled by an input error, the stroke will be affected. walk around
