Embodiment Construction

[0010] Below the present invention will be further described in conjunction with the embodiment of accompanying drawing:

[0011] The gap adjustment mechanism of the CNC cutting machine of the present invention is mainly composed of a frame 1, a fixed seat 2, a copper sleeve 3, a rotating shaft 4, a mounting seat 5, a gear 6, a rack 7, a bearing 8, a spacer 9, a reducer 10, and a screw 11. Spring 12, nut 13, first bolt 14, second bolt 15 and so on.

[0012] The transmission gap adjustment mechanism of the CNC cutting machine of the present invention mainly adopts the fixed seat 2 to be installed on the frame 1 by the second bolt 15, and the left and right vertical can be adjusted by the first bolt 14, and the mounting seat 5 is connected by the rotating shaft 4 and the copper sleeve 3. Rotation, the gear 6 is connected with the output shaft of the reduction box 10, the outer ring of the gear 6 is equipped with a bearing 8 to play a protective role, the spacer 9 presses the out...

Abstract

The invention relates to a transmission gap adjusting mechanism of a gantry numerical control cutting machine, which is mainly as follows: bearings are mounted in a mounting seat, a spacing sleeve is used for positioning between the bearings, the spacing sleeve compresses outer rings of the bearings, a speed reducer is fixed on the mounting seat, a gear is connected with an output shaft of the speed reducer, a fixed seat is arranged in a copper sleeve, the mounting seat is connected with the fixed seat by a rotating shaft, the fixed seat is mounted on a frame by a first bolt and a second bolt, a screw rod is screwed in the frame, a spring is arranged in the screw rod, a nut is screwed in and compresses the gear, and the gear is meshed with a rack. The first bolt is used for regulating the verticality between the gear and the rack. The transmission gap adjusting mechanism of the numerical control cutting machine has simple structure, convenient regulation and large assembly space, and can facilitate the processing of the frame, improve the rigidity of the frame, reduce the phenomenon of fracture of the expensive output shaft of a reduction gearbox, reduce the maintenance ratio of replacing the reduction gearbox, further reduce the manufacturing cost and improve the product quality.

Description

technical field [0001] The invention relates to a transmission gap adjustment mechanism of a gantry numerical control cutting machine, specifically a longitudinal reciprocating movement mechanism applied in numerical control cutting equipment, and belongs to the technical field of cutting equipment. Background technique [0002] At present, the transmission gap adjustment mechanism used in CNC cutting equipment is installed in the middle of the frame, with small gap adjustment space, high requirements for frame processing, and a long cycle. The limit error during processing is difficult to adjust, and it is easy to cause the gear and rack to mesh poorly. Therefore, the phenomenon of gear wear is prone to occur during operation, resulting in frequent maintenance and correspondingly increasing manufacturing costs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, thereby providing a transmission gap adju...
