Abstract

The utility model relates to a chute grinding clamp, which comprises a clamp body and a pressing plate positioned on the clamp body, wherein one end of the pressing plate is supported by a supporting column, the other end of the pressing plate is pressed on a processed part, and the center of the pressing plate is fastened to the pressing plate by a hexagon screw with a shoulder and a stud; the clamp comprises a clamp body and is characterized in that a V-shaped block for bearing a processed part is arranged on the upper portion of the clamp body and below a pressing plate, the V-shaped block is fixed on the clamp body through an inner hexagonal cylindrical head screw and a positioning pin in a matched mode, positioning columns and stop blocks are arranged on two sides of the V-shaped block respectively, the positioning columns are arranged on positioning column bases, and the positioning columns can move back and forth and are fixed through set screws. By arranging the adjustable positioning column, the length of the machined part can be adjusted, and the adaptability is strong; meanwhile, the contact area between the part and the supporting part can be reduced through the support of the V-shaped block and the sliding supporting block, the resonance of the part and the supporting structure in the machining process is reduced, the machining precision is improved, the position of the sliding supporting block can be flexibly adjusted according to the gravity center position of the part, and the minimum deformation of the part in the machining process is ensured.

Description

Clamp for grinding chute

Technical Field

The utility model relates to a fixture device field specifically is a grind chute anchor clamps.

Background

Chinese utility model patent CN204321842U discloses an anchor clamps of oblique notch is ground to axle sleeve for processor, its bottom plate is platelike cuboid, the bottom plate four corners has the hole fixed with grinding machine table surface, bottom plate one side surface has the chute parallel with part notch root inclined plane, the V type frame has been inlayed on the chute, the inside symmetric connection of V type frame and V type clamp plate, V type frame, bottom plate extremely up and down by the bolt fixed connection at V type clamp plate both ends, this anchor clamps can swiftly conveniently clamp irregularly shaped part on the grinding machine, only need add the adjustment slightly, and correction that can be accurate has shortened operating time and improvement work efficiency to let the operating stability and the reliability of product improve greatly. But still has the following disadvantages: when the inclined groove is drilled, the part is subjected to forces in two directions, and when the position of the part on the bottom plate is adjusted according to the size of the part, the position of the center of gravity changes, so that errors caused by the change of the center of gravity can be large for machining precision parts, and the machining precision of the part is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a grind chute anchor clamps is provided to solve the defect that exists among the prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

a chute grinding clamp comprises a clamp body and a pressing plate positioned on the clamp body, wherein one end of the pressing plate is supported by a supporting column, the other end of the pressing plate is pressed on a machined part, and the center of the pressing plate is fastened to the pressing plate through a hexagon screw with a shoulder and a stud; a V-shaped block for bearing a processed part is arranged on the upper part of the fixture body and below the pressing plate, the V-shaped block is fixed on the fixture body through an inner hexagonal cylindrical head screw and a positioning pin in a matching way, a positioning column and a stop block are respectively arranged on two sides of the V-shaped block, the positioning column is arranged on a positioning column seat, and the positioning column can move back and forth and is fixed through a set screw;

furthermore, the stop block is fixed by an inner hexagonal socket head cap screw and a set screw;
