Efficient low-cost linear guide rail device

The utility model discloses an efficient low-cost linear guide rail device which comprises a linear guide rail, a sliding block, an upper sealing baffle, a lower sealing baffle, a rolling body, a rolling body sliding way, a rolling body pipeline and a rolling body return way, and the lower sealing baffle is assembled at the bottom of the sliding block in a welding mode. The lower sealing baffle at the bottom of the sliding block is assembled and fixed to the sliding block in a welding mode, the welding mode replaces a bolt assembly mode to assemble the lower sealing baffle, on one hand, threaded holes can be prevented from being machined in the bottom of the sliding block, the production efficiency is improved, on the other hand, the bolt locking assembly time can be saved, and the production efficiency is improved. The assembling time of the lower sealing baffle is greatly shortened, and the production cost is reduced. 本实用新型公开了一种高效低成本直线导轨装置，包括直线导轨、滑块、上密封挡板、下密封挡板、滚动体、滚动体滑道、滚动体管道及滚动体回道，下密封挡板通过焊接的方式进行组装在滑块底部，本实
