Embodiment Construction

[0013] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0014] As shown in the figure: the transmission locking device includes a mounting plate 1, a servo motor 10, a reducer 7, a rack 9 and an elastic device. Wherein the servo motor 10 is connected with the reducer 7 and is slidably installed on the mounting plate 1 by the motor base 3 , and the output shaft of the reducer 7 is provided with a gear 8 . The gear 8 is pressed against the rack 9 by an elastic device, and the rack 9 and the elastic device are located on the same side of the gear 8. To ensure transmission accuracy, the gear 8 and the rack 9 adopt high-precision structures. The elastic device comprises a screw mandrel 6, a nut seat 4, a nut 5 and a spring 2, wherein the nut seat 4 is installed on the mounting plate 1, and one end of the screw mandrel 6 passes through the nut seat 4 to connect to the motor seat 3, and is used to drive the nu...

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a transmission locking device, which is suitable for large and long machine tools. Background technique [0002] In the prior art, the transmission of machine tools mainly adopts screw nut pair and rack and pinion pair. Among them, the screw shaft is not suitable for long distances, and the rack can be extended freely. At the same time, the conventional rack and pinion pair has poor contact when moving. , jumping teeth, jamming when there are foreign objects and other defects. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provides a transmission locking device, which is suitable for long-distance transmission, and has stable performance, and will not cause poor contact, tooth jumping, and jamming. [0004] According to the technical solution of the present invention, the transmission locking device includes a mounting pla...
