Description

A Simple Measuring Tool for Dimension Measurement of Two Arc Surfaces of Double R Blades

technical field

The utility model relates to a simple measuring tool, in particular to a simple measuring tool for measuring the dimensions of two circular arc surfaces of double R blades.

Background technique

The distance dimension W between the two arc surfaces of the oil pump vane is relatively strict (W±0.01), while the distance dimension between the two arc surfaces of the traditional double-arc small blade is W±0.1, which is easier to process and inspect, especially the W dimension , due to the large tolerance, it is usually sufficient to use a micrometer to perform a random inspection according to a certain ratio. However, the oil pump blades are more difficult to process and inspect. Through the improvement of the process, the W size can meet the requirements of the drawings, and full inspection is required. Then there is the problem of inspection. The usual inspection method is to use a micrometer as a single piece. Inspection, for small batches, can barely cope with it. With the mass production of blades, single-piece inspection methods appear to be inefficient and inaccurate, which can no longer keep up with the pace of mass production.

Utility model content

Aiming at the problems existing in the prior art, the utility model provides a simple measuring tool for measuring the dimensions of the two arc surfaces of the double R blades to solve the above problems.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A simple measuring tool for measuring the dimensions of two arc surfaces of double R blades, including a base, characterized in that: a square groove is longitudinally arranged in the middle of the base, and a blade to be measured is arranged in the square groove. One side of the blade to be tested leans against the upper edge on the left side of the square groove, and the other side leans against the bottom surface of the square groove and contacts the right side of the square groove. A meter frame is fixed on the left edge of the base, and the meter frame There is a through hole inclined to the lower right, the direction of the through hole passes through the upper left edge of the square groove and the lower edge of the right side and is perpendicular to the upper left edge of the square groove. The dial gauge measuring head is in contact with an edge of the blade to be tested, and the dial gauge and the gauge frame are fixed by pressure gauge screws. The design of square groove, table frame and dial indicator makes it possible to use standard blocks for comparison and detection during detection, and accurately and quickly conduct full inspection of workpiece size, which greatly improves the detection efficiency and detection accuracy.

Further, the base is square, simple in structure and reasonable in design.

Further, the watch frame is in an inverted "T" shape, simple in structure and reasonable in design.

Compared with the prior art, the simple measuring tool for measuring the dimensions of the two arc surfaces of the double R blades of the utility model adopts the design of a square groove, a table frame and a dial indicator, so that the standard block can be used for comparison and detection during detection, which is accurate and accurate. Quickly carry out full inspection on the workpiece size, which greatly improves the detection efficiency and detection accuracy.

Detailed ways

In order to further understand the utility model, the utility model is described below in conjunction with the accompanying drawings.

As shown in Figure 1, a simple measuring tool for measuring the dimensions of two arc surfaces of a double R blade provided in this embodiment includes a base 1, and a square groove 2 is longitudinally arranged in the middle of the base 1, and the square groove 2 The blade to be tested is arranged in the groove, and the blade to be tested 3 leans against the upper edge on the left side of the square groove 2 on one side, and the other side leans against the bottom surface of the square groove 2 and contacts the right side of the square groove 2, and the base 1. A watch frame 4 is fixed on the left edge, and the watch frame 4 is provided with a through hole 5 obliquely to the lower right. The direction of the through hole 5 passes through the square groove 2 on the left upper edge and the right lower edge And perpendicular to the upper edge on the left side of the square groove 2, a dial gauge 6 is provided in the through hole 5, and the measuring head of the dial gauge 6 is in contact with an edge of the blade 3 to be measured. Frame 4 is fixed by gauge screw 7.

Each component of this embodiment is explained:

1) Base 1 is square.

2) The table frame 4 is an inverted "T" shape.

Working principle: Use the standard block for comparison and detection, first select the standard block that is the same as the workpiece W to be inspected, place the standard block in the square groove, place one side in the square groove, and lean on the left edge of the square groove, Then use the dial gauge measuring head to touch the edge of the standard block, adjust the dial gauge to 0, fix the position of the dial gauge with the pressure gauge screw, and then push the workpiece along the square groove through the dial gauge measuring head , at this time, the hands will swing left and right. If the indication value of the hands is between +0.01 and -0.01, it means that the size of the workpiece is qualified, and if it exceeds this range, it is unqualified.

The above are only preferred embodiments of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, various deformations and improvements can also be made, which should also be regarded as Protection scope of the present utility model.
