The clamping part of the clamping arm is an L-shaped surface, and the clamping part of the positioning arm is provided with a V-shaped opening, and the shape of the V-shaped opening matches the shape of the tenon of the precision forged blade.

The lower end of the V-shaped opening of the positioning arm is provided with a groove.

Both the clamping arm and the positioning arm are provided with threaded holes, and are fixed with a common bench vise by screws.

Compared with the prior art, the utility model fixes the universal vise on the three-coordinate measuring machine platform, uses the clamping arm and the positioning arm with adjustable position distance to clamp the precision forging blade, and the clamping arm and the positioning arm clamp the forging blade. The shape of the clamping part matches the shape of the mortise of the precision forged blade. After the same batch of blades are aligned at one time, the specific blade does not need to be aligned, and it is directly clamped in the clamping surface of the positioning arm. The blade can be measured; the precision forging blade three-coordinate measuring fixture is used for alignment, which greatly shortens the alignment time and improves the measurement efficiency; because the utility model is connected with the general bench vise, the general bench vice does not need to make any changes, Compact structure, low manufacturing cost, simple maintenance, universal and interchangeable, stable structure, easy to use, very high utilization rate and long-term use.

Further, the clamping arm is fixed on the moving side of the general bench vise, and the positioning arm is fixed on the fixed side of the general bench vise, and the handle of the general bench vise is turned, and the clamping arm moves with the moving side, so that the clamping arm and the positioning arm Direct distance is adjustable.

Furthermore, the clamping surface of the positioning arm is provided with a V-shaped opening, and the tenon of the precision forged blade is clamped in the V-shaped opening, which can fully fit the clamping surface. The clamping arm is in point contact with the precision forging blade, and the positioning arm It is in surface contact with the precision forged blade, which ensures the stability of the clamping and facilitates the alignment.

Furthermore, the V-shaped bottom of the V-shaped opening of the positioning arm is provided with grooves to prevent the interference of the burrs at the corners of the tenon of precision forged blades on the positioning, and ensure the alignment of the position.

Detailed ways

Referring to Figures 1-4, the utility model includes a general-purpose bench vise 1 arranged on a three-coordinate measuring machine platform, the jaws of the general-purpose bench vise 1 are provided with a clamping arm 2 and a positioning arm 3, and the clamping The distance between the arm 2 and the positioning arm 3 is adjustable, and the clamping parts on the clamping arm 2 and the positioning arm 3 match the shape of the tenon of the precision forged blade 4 . The clamping arm 2 is fixed on the moving side of the universal bench vise 1 , and the positioning arm 3 is fixed on the fixed side of the universal bench vise 1 . The clamping arm 2 is arranged in an L shape, and the positioning arm 3 is arranged in an inverted L shape capable of cooperating with the clamping arm 2 . The clamping part of the clamping arm 2 is an L-shaped surface, and the clamping part of the positioning arm 3 is provided with a V-shaped opening. The lower end of the V-shaped opening of the positioning arm 3 is provided with a groove. Both the clamping arm 2 and the positioning arm 3 are provided with threaded holes, and are fixed with the universal bench vise 1 by screws.

The utility model is composed of a universal bench vise 1, a clamping arm 2 and a positioning arm 3. The universal bench vise 1 is fixedly installed on the workbench of a three-coordinate measuring machine, and clamping is installed on both sides of the universal bench vise 1 jaw. The arm 2 and the positioning arm 3; the clamping arm 1 is processed into an L-shaped surface, and the positioning arm 3 is processed into a V-shaped surface; both arms have threaded holes for connecting with the general bench vise 1.

The process of using the utility model is as follows: firstly fix the fixture on the working platform of the three-coordinate measuring machine, then adjust the distance between the jaws of the universal bench vise 1 to clamp the precision forging blade 4, and establish the initial coordinate system based on the fixture for the first piece, Then call the blade shape measurement program to automatically measure the blade shape. Because the clamping part of the fixture can fit with the tenon of the blade, it can ensure that the blade clamping position remains high and consistent each time. Except for the manual alignment of the first piece, the automatic blade measurement procedure is only required for multiple consecutive measurements, which simplifies the operation content and shortens the alignment time, so that the measurement can enter the measurement state faster.

The utility model takes the universal bench vise 1 as the main component, and installs the clamping arm 2 and the positioning arm 3 through the threaded hole in the jaw of the universal bench vise 1. It has the advantages of stable structure, convenient use, high utilization rate and long-term use. advantage. Fix the precision forging blade three-coordinate measuring fixture on the three-coordinate measuring machine platform, and after aligning the blades of the same batch at one time, there is no need to align the specific blades, and it is directly clamped on the V-shaped surface of the positioning arm The blade can be measured within the blade; the precision forging blade three-coordinate measurement fixture is used for alignment, which greatly shortens the alignment time and improves the measurement efficiency; because the utility model is connected with the general bench vise, the general bench vice does not need to do anything The utility model has the advantages of compact structure, low manufacturing cost, simple maintenance, general purpose and interchangeability.
