Large-stroke, rapid and accurate linear feeding production line

Abstract

The invention discloses a large-stroke, rapid and accurate linear feeding production line, and belongs to the technical field of servo positioning control. Two parallel linear guide rails are installed on a tool body, and a rack is fixed on the inner side of one of the linear guide rails; linear sliding blocks are slidably installed on the linear guide rails, and a sliding plate is fixedly connected to the two linear sliding blocks; a servo motor is installed on the sliding plate, and the servo motor is connected with the rack through a transmission mechanism; an automatic lubricating device is further installed on the sliding plate; and two ends of the tool body are provided with adjustable tug mechanisms respectively. According to the linear feeding production line, when the sliding plate works every time, a mechanical zero point serves as a reference, so that the accumulative error is avoided, and rapid and accurate positioning is realized; a gear, the rack, linear guide rails and aplanetary gear are adopted, so that large rigidity power is provided for the production line, and axial positioning can be accurately realized; and the automatic lubricating device provides continuous lubricating oil for the gear, racks, the linear guide rails and the like, so that the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of servo positioning control, in particular to a large-stroke, fast and precise linear feed production line suitable for automatic and precise positioning of longer profiles and instructing other equipment for automatic processing. Background technique [0002] At present, one of the processing methods for longer workpieces (profiles) is manual positioning, that is, placing the workpiece on the rollers of the workbench, positioning it behind, pushing the workpiece to the positioning plate manually, and processing the workpiece (drilling, punching, sawing, etc.), when processing the next step, repositioning, the accumulation of errors is serious; another processing method is circular guide rail guidance, gear and rack transmission, and the transmission mode is that the servo motor transmits power through the synchronous belt. [0003] The first processing method is more traditional and widely used, but the po...

Problems solved by technology

[0003] The first processing method is more traditional and widely used, but the positioning speed is slow, the cumulative error is large, and more human resources are used, which is not conducive to the production of modern processing methods.

The second processing method greatly improves the production efficiency. However, due to the low precision of the guide rail used and the insufficient rigidity of the transmission method (synchronous belt), the error is large, and the lubrication of the gear, rack, guide rail, etc. requires the operator to work in advance. , Completed after work, sometimes when the workload is large, it is easy to be ignored, resulting in a greatly reduced service life of gears, racks and guide rails
