Description

Tool Precision Grinding Fixture

technical field

The utility model relates to a tool sharpening fixture, in particular to a tool precision grinding fixture.

Background technique

The quality of the grinding groove and back of the cemented carbide micro-drill directly affects the drilling quality, processing efficiency and service life. At present, most of the cemented carbide micro-drills use a combination of three fixtures for grinding grooves and backs: collet clamping, tungsten steel guide sleeves with the same diameter as the drill shank guiding, and ejector rods for auxiliary tightening. The disadvantages are: the machining accuracy of each part of the fixture is high, and the three are difficult to be coaxial, resulting in rapid wear of the tungsten steel guide sleeve and the spring collet, the quality and life of the drill bit cannot be guaranteed, and the production cost is high; the aperture of the tungsten steel guide sleeve is fixed. , cannot adapt to the clamping of micro-drills with different shank diameters; the machining accuracy of the tungsten steel guide sleeve is high, it is a special part, and the production cost is high.

Contents of the invention

The utility model is realized in this way, which includes clamp body, screw rod, adjusting nut, lock nut, same seat, adjusting screw, V-shaped block, locking screw, guide key, adjusting screw rod, spring, pressing plate, rotating support , revolving pin, pin shaft, loose clamp oil cylinder, V-shaped pressure block, which is characterized in that there is a through hole with an axial slit in the clamp body, and one end of the screw passes through the through hole to cooperate with the adjustment nut and the lock nut. The other end is connected to the fixed seat, and the fixed seat is connected to the V-shaped block through the adjustment screw. Two locking screws perpendicular to the axial slit shrink the slit and clamp the screw tightly. The side wall of the screw has a guide key, and the clamp body One side of the adjustment screw is connected to the adjustment screw, the adjustment screw is connected to the spring, the spring is connected to one end of the pressure plate, the other end of the pressure plate is connected to the revolving pin through the rotating support, the pressure plate is connected to the release cylinder through the pin shaft, and the release cylinder is fixed on the other end of the clamp body , the middle part of the pressing plate is connected with a floating V-shaped pressing block, and the V-shaped pressing block corresponds to the position of the V-shaped block.

The technical effect of the utility model is: adopting the V-shaped block with adjustable position for guiding and positioning can ensure that the V-shaped block is coaxial with the spring collet, and the processing quality of the workpiece can be guaranteed; the standard V-shaped block is selected, and the replacement is convenient and fast , Low cost; the position of the V-shaped block can be adjusted, which can adapt to the clamping and processing of micro-drills with different shank diameters.
