Claims (1)

[Scope of utility model registration request] In a pitch feed device that moves a table on which a workpiece is placed at a fixed pitch, a position indexing hole corresponding to the table feed pitch is provided in the table guide track attached to the fixed base, and the table guide is attached to the table. The first plunger, which is fitted into the position indexing hole provided in the track and urged toward the projecting side by a spring or the like, locks the table each time the pitch is set, and a linear guide groove provided in the housing integrated with the table. A slider that slides inside and is stably locked at both sliding ends by a first plunger and a second plunger attached to the housing, and has two recesses for engaging the plungers, and a slider that is L-shaped in shape. A swinging lever is provided which is swingably connected to the slider at an L-shaped corner, and one end of the swinging lever is rotatably connected to a linear drive means such as an air cylinder. A claw that can be engaged with the position indexing hole is attached to the other end, and a switch is provided at both ends of the linear guide groove to change the sliding direction of the linear drive means, and the position of the position index hole provided on the table guide track is connected to the table. A slider with a swing lever and a propulsion function that equalizes the spacing and the travel distance in the linear guide groove of the slider that slides in the linear guide groove in the housing, and performs pitch feeding of the table by linear movement in the front and back direction by the linear drive means. A pitch feeding device characterized by a configuration of functions.
