摘要： A woodworking lathe adjustment structure includes a base having an axial slide trough thereon, a head unit and a tail unit disposed on the base. An adjustment block is provided between the head unit/the tail unit and the slide trough. The adjustment block includes a groove, a space adjustment bolt, and an adjustment bolt. The groove has a compelling hole therein. The compelling hole has a threaded section and a non-threaded section therein. The space adjustment bolt is screwed to the threaded section. The adjustment block is secured to the bottom of the head unit/the tail unit by fixing bolts, respectively, and inserted in the slide trough. When the space adjustment bolt passes the non-threaded section of the compelling hole, the sides of the groove will be deformed outward and curvedly to offset a gap which is caused by wear and tear of the adjustment block and the slide trough.

摘要： A movement auxiliary device for a machine stand includes a foot stand. Two sides of the lower end of the foot stand are provided with first and second side seats having vertical rail grooves, respectively. A movable lever, a pivot seat and a lifting roller assembly are provided between the two rail grooves. The foot stand is provided with a support seat. A connecting board having a pedal is pivotally connected between the support seat and the pivot seat, which can be pivoted on the pivot seat. The movable lever is pivotally connected with a pneumatic cylinder to provide a buffering function for the lifting roller assembly and the machine stand. The pedal is controlled for the connecting board and the pivot seat to generate a link pivot, such that the lifting roller assembly is descended to the ground or ascended upward.

摘要： A working height adjustment device of a processing machine includes a retaining frame, a slide seat, and a lever having a connecting rod pivoted between the retaining frame and the slide seat. An adjustment seat of the slide seat has an accommodation hole. The accommodation hole is provided with an elastic member, a movable member, and an eccentric rod. The movable member has an engaging hole. The engaging hole has a diameter greater than that of a micro adjustment screw rod. The engaging hole has a toothed portion. Thereby, the eccentric rod is turned to push or release the movable member for the toothed portion of the engaging hole to engage with or disengage from a threaded section of the micro adjustment screw rod, such that the micro adjustment screw rod is tuned or the lever is pulled up and down to adjust the cutter seat quickly.
