Abstract

The utility model provides a grinding clamp of a blade lacing wire and relates to a grinding clamp. The grinding clamp aims at solving the problem that blade processing accuracy is low at present. The grinding clamp comprises a clamp body, a pressing plate, a plurality of compression springs, a plurality of positioning screws and a plurality of clamping screws, a boss is respectively arranged on the front lateral side and the rear lateral side of the clamp body, a semi-circular groove is arranged on the upper end face of the side wall of the clamp body, a process clearance groove is arranged at the root of the semi-circular groove, a plurality of threaded holes are arranged on the upper end face of the clamp body, the positioning screws penetrate through the compression springs and the corresponding threaded holes so as to enable the pressing plate to be positioned on the clamp body, and the clamping screws penetrate through the corresponding threaded holes and utilize the pressing plate to enable the blade lacing wire to be clamped on the clamp body. The grinding blade is used for processing the blade lacing wire.

Description

The blade lacing clamp

Technical field

The utility model relates to a kind of clamp.

Background technology

Lacing wire is installed in the blade lacing hole during assembling, and every circle blade is connected as a single entity.This lacing wire radical length is 12.45 (+0.1/0), adopts the manual two ends radius that grinds of pincers worker in the past, and not only the radius size of processing is uneven, and working (machining) efficiency is low.

The utility model content

The purpose of the utility model provides a kind of blade lacing clamp, to solve the lower problem of present blade processing precision.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: said anchor clamps comprise clamp body, pressing plate, a plurality of compression spring, a plurality of dog screw and a plurality of pinching screw; The front and back sides of clamp body respectively is provided with a boss; Have half-arc groove on the sidewall upper face of clamp body; The root of half-arc groove has the technology undercut; Have a plurality of screwed holes on the upper surface of clamp body, dog screw passes the compression spring and corresponding screwed hole is positioned at pressing plate on the clamp body, and pinching screw passes corresponding screwed hole and utilizes pressing plate that blade lacing is clamped on the clamp body.

The utlity model has following beneficial effect: the utility model replaces the manual lacing wire two ends radius that grinds with machine tooling, and not only each part blade lacing dimensional uniformity of processing is good, and working (machining) efficiency also greatly improves.Use through actual, effect is fine, has not only satisfied radical length 12.45 (+0.1/0) required precision, and has improved the uniformity of each part blade lacing radial dimension processing, can reach in the 0.03mm.

Fig. 1 is the utility model overall structure front view, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the vertical view of Fig. 1, and Fig. 4 is the structural front view of clamp body, and Fig. 5 is the left view of Fig. 4, and Fig. 6 is the vertical view of Fig. 4.

The specific embodiment

The specific embodiment one: combine Fig. 1 and Fig. 2 that this embodiment is described; The said anchor clamps of this embodiment comprise clamp body 1, pressing plate 2, a plurality of compression spring 3, a plurality of dog screw 4 and a plurality of pinching screw 5; The front and back sides of clamp body 1 respectively is provided with a boss 1-1; Have half-arc groove 1-2 on the sidewall upper face of clamp body 1; The root of half-arc groove 1-2 has technology undercut 1-3; Have a plurality of screwed hole 1-4 on the upper surface of clamp body 1, dog screw 4 passes compression spring 3 and corresponding screwed hole 1-4 is positioned at pressing plate 2 on the clamp body 1, and pinching screw 5 passes corresponding screwed hole 1-4 and utilizes pressing plate 2 that blade lacing 6 is clamped on the clamp body 1.

Half-arc groove 1-2 cooperates with blade lacing 6, is used for location, mounting blades lacing wire 6, and technology undercut 1-3 makes blade lacing 6 and half-arc groove 1-2 fit tightly, and utilizes boss 1-1 that this clamp body 1 is clamped on the platen.

The specific embodiment two: combine Fig. 1 that this embodiment is described, the bottom face both sides of the clamp body 1 of this embodiment respectively have a concave station 1-5, are used to lay the terminal of pressing plate 2 and support pressing plate 2.Other embodiment is identical with the specific embodiment one.
