Abstract
The utility model discloses a thread grinding fixture for screw taps. The thread grinding fixture comprises a matrix, a positioning cutting board, an apex and a clamping mechanism; the positioning cutting board and the apex which correspond to each other are mounted on the matrix; the clamping mechanism comprises a movable block, a fixed block and a rotary block, the fixed block is fixed onto the matrix, the movable block is mounted on the matrix by a rotary pin, and the rotary block is mounted on the matrix by a rotary pin; a pull pin is disposed on the rotary block, and a slide groove corresponding to the pull pin is arranged on the movable block; and grooves with semicircular sections are arranged on both the movable block and the fixed block, and sections of the two grooves form a circle after the two grooves are closed. When the thread grinding fixture is used, a threaded portion of a screw tap is centered by the movable block and the fixed block which are matched with each other, the movable block is opened and closed to clamp a workpiece, and is matched with the apex to position the workpiece, and the thread grinding fixture has the advantages of convenience in operation, accuracy in positioning, high positioning efficiency and the like.
Description
Technical field
The utility model relates to a kind of screw tap thread grinding anchor clamps.
Background technology
Pitch is used first the cylindrical die roll rolled thread at the machine tap more than 0.7 before quenching, the allowance of regrinding after the quenching.The screw thread mill is with the top dead axle heart of two ends, and screw tap itself is clamped with " peach " chuck in the angle position, refills dialling on the justice at grinding machine spindle.Prior art generally all be before back centre location, to the spiral shell button, and by dial gauge counterpart position, its weak point is that location efficiency and precision are lower with 60 ° of edges of a knife.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of screw tap thread grinding anchor clamps, to improve positioning accuracy and the efficient of screw-tap threaded processing.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of screw tap thread grinding anchor clamps comprise matrix, are installed on the described matrix and corresponding location knife plate and top, also comprise clamp mechanism; Described clamp mechanism comprises movable block, fixed block and switch block, and described fixed block is fixed on the described matrix, and described movable block is installed in by shipping and reselling on another market on the described matrix, and described switch block is installed on the described matrix by shipping and reselling on another market; Be provided with finger on the described switch block, be provided with the chute of corresponding described finger on the described movable block; Be provided with the groove that the cross section is semicircle on described movable block and the fixed block, and the cross section after two described groove closures is rounded.
Preferably, also be fixed with fixture block on the described switch block, shipping and reselling on another market on described fixture block and the described switch block is fixedly connected with.
Pass through technique scheme, the screw tap thread grinding anchor clamps that the utility model provides, movable block and the fixed block that cooperatively interacts adopted in the centering at screw-tap threaded position, opening and closing clamping work pieces by movable block, and cooperate toply with workpiece location, have easy to operate, registration, location efficiency advantages of higher.
